DISMANTLING THE SAME

TECHNICAL FIELD

[001] The present disclosure relates to common towers configured to allow hoisting facilities to be installed adjacent and along building structures, providing transportation of personnel and materials into high-rise buildings under construction. More particularly, the present disclosure relates to assemblies for erecting and dismantling common towers adjacent high-rise buildings under construction and to methods of erecting and dismantling the same.

BACKGROUND

[002] Common towers are well known in the art for allowing hoisting facilities, machines and/or equipment to be installed adjacent and along building structures, such as new building constructions and renovation projects, providing minimum interferences to the construction site itself. Such towers allow for transportation of personnel and materials into high-rise buildings under construction.

[003] Hoisting facilities, machines and/or equipment of all types may be tied to and grouped around common tower structures. Usage of a common tower therefore maximizes access to the building structure while minimizing the number and size of access openings provided into the building under construction.

[004] Common towers found in the art that are configured to receive up to six hoisting equipment, each comprises a heavy mast structure (up to 400-500 pounds for a 5 feet mast section) that is adapted to receive the numerous flooring structures as well as the hoisting equipment themselves.

[005] There is therefore a need for mast-free lighter assemblies and components configured to easily/safely erect and dismantle common towers such as to provide easy/safe transportation of personnel and materials into high-rise buildings under construction.

DETAILED DESCRIPTION

[0080] Referring now to the drawings and more particularly to Figures 1 and 2, there is shown an assembled/erected common tower 10, or tower 10, which is configured to be mounted/positioned adjacent a high-rise building structure in construction (not shown), such as adjacent a new building construction or adjacent a renovation project. Up to six hoisting equipment, facilities and/or machines of all types may thus be tied to and grouped around tower 10 once assembled/erected.

[0081] Still referring to Figures 1 and 2, there is shown that tower 10 comprises four spaced apart columns 12a, 12b, 12c, 12d adapted to be spacedly and vertically positioned adjacent the building structure and a plurality of vertically spaced apart flooring structures 14a, 14b, 14c which are releasably and slidably supported by spaced apart columns 12a, 12b, 12c, 12d. Columns 12a, 12b, 12c, 12d together with flooring structures 14a, 14b, 14c define three common tower floors 13a, 13b, 13c. A person skilled in the art to which tower 10 pertains (provided for high-rise building constructions) would understand that even if only three flooring structures 14a, 14b, 14c, or common tower floors 13a, 13b, 13c, are shown in Figures 1 and 2, tower 10 may include two flooring structures or more (or two common tower floors or more), as long as it provides the needed number of flooring structures to fully support the hoisting equipment along the building structure, which itself includes a predetermined number of building levels. Generally, tower 10 will include a number of flooring structures (or a number of common tower floors) that corresponds to the number of levels associated with the high-rise building structure.

[0082] As better shown in Figure 3, where only one flooring structure 14a and only one common tower floor 13a are illustrated, tower 10 further comprises an anchoring system 18 which is adapted to be fixed to (to securely engage) the building structure to maintain columns 12a, 12b, 12c, 12d as well as flooring structure 14a upright. Each common tower floor (one common tower floor shown in Figure 3) may include its own anchoring system 18, but alternatively, only some of the common tower floors may include an anchoring system 18, as long as the plurality of anchoring systems 18 together provide sufficient strength to maintain tower 10 upright adjacent the building structure (usually provided where elevator's anchors are provided). Additionally, it is to be noted that a person skilled in the art to which tower 10 pertains would understand that even if four spaced apart columns 12a, 12b, 12c, 12d are illustrated in Figures 1 and 2, three or more columns may be used to assemble/erect such a common tower. According to these plurality of scenarios, less or more hoisting equipment may be tied to and grouped around the common tower. Moreover, such as to increase the number of hoisting equipment that may be tied to, and grouped close to, the building structure, more than one common tower 10 may be positioned adjacent one to the other. For example, a second tower 10 may be installed adjacent a first common tower 10 (where first common tower 10 is found to be adjacent building structure), using columns 12a, 12d. According to such a scenario, for one common tower floor, only six columns would support two horizontally aligned flooring structures, such as to provide ten individual accesses to the building structure. Such second tower 10 may also be provided to support a stairwell or a staircase opening, for example.

[0083] Still referring to Figures 1 and 2, there is shown that tower 10 further comprises protection structures 20a, 20b, 20c which are releasably mounted on each flooring structure 14a, 14b, 14c and/or columns 12a, 12b, 12c, 12d so as to upwardly extend from the flooring structures. Each protection structure is adapted to surround a main deck, and alternatively a secondary deck, being part of the flooring structure, as it will be described in more details below. Protection needs may vary from one common tower to another, such as to accommodate different hoisting needs. As it will be described in more details below, tower 10 further comprises a plurality of connectors releasably connecting the multiple components together, namely, columns 12a, 12b, 12c, 12d, flooring stmctures 14a, 14b, 14c, anchoring system 18, and protection structures 20a, 20b, 20c. Moreover, as it will be shown, many of the connectors provided to assemble/erect and disassemble/dismantle tower 10 are secured to columns 12a, 12b, 12c, flooring structures 14a, 14b, 14c, anchoring system 18, and/or protection structures 20a, 20b, 20c, providing a safer use of tower 10, during and after its erection.

[0084] Referring now more particularly to Figures 4A to 4L, there is shown that each column 12a, 12b, 12c, 12d is made from a plurality of longitudinally aligned column hollow sections 24 (lower column hollow section 24 and upper column hollow section 24 shown in Figures 4I, 4K).

[0085] As well illustrated in Figures 4A, 4B, each column hollow section 24 defines a column section axis 25. Each column hollow section 24 is further configured to be releasably connected/assembled to an adjacent column hollow section 24. Indeed, each column 12a, 12b, 12c, 12d further comprises a plurality of column section-to- section connecting members (Figures 4F, 4G, 4H). Each column section-to-section connecting member 26 is adapted to releasably engage with two adjacent column hollow sections (Figure 4K).

[0086] As well illustrated in Figures 4A-4E, each column hollow section 24 defines an inner surface 27, an outer surface 28 and four spaced apart longitudinal grooves 30a, 30b, 30c, 30d (the primary longitudinal grooves) radially aligned and formed within outer surface 28 (along overall length of column hollow section 24). Each column hollow section 24 further defines four spaced apart longitudinal grooves 31a, 31 b, 31c, 31d (the secondary longitudinal grooves), formed inbetween longitudinal grooves 30a, 30b, 30c, 30d. As better shown in Figures 4A, 4C, 4D, spaced apart openings 32 are longitudinally aligned within longitudinal grooves 30a, 30b, 30c, 30d. Openings 33 are further formed/provided within longitudinal grooves 31a, 31 b, 31c, 31 d.

[0087] Referring now more particularly to Figures 4F, 4G, 4H, there is shown that column section-to-section connecting member 26 comprises a hollow main body 34, a first set of apertures 36 and a second set of apertures 37 formed therethrough. Each column sectiori-to-section connecting member 26 defines a connecting member axis 29 (Figure 4G). As shown in Figure 4I, two adjacent column hollow sections 24 are releasably secured together via a first/lower column section-to- section connecting member (not shown), and a third column hollow section (not shown) may be releasably secured to hollow main body 34 of second/upper column section-to-section connecting member 26. For example, for each column 12a, 12b, 12c, 12d, two column hollow sections 24 may be longitudinally aligned and releasably secured together for each one of the common tower floors, as one column hollow section may have a length, for example, of about 6 feet. More or less column hollow section(s) may however be used to assemble/erect one common tower floor. Still referring to Figures 4F-4H, there is shown that hollow main body 34 defines a main body outer surface 38 adapted to interface with inner surface 27 of column hollow sections.

[0088] Referring now to Figure 4A, there is shown that each one of the plurality of column hollow sections 24 together forming the spaced apart columns 12a, 12b, 12c, 12d, defines a first end/edge (or lower end/edge) 41a and a second end/edge (or upper end/edge) 41b. Therefore, each column 12a, 12b, 12c, 12d may be supported by a column base member 40a, 40b, 40c, 40d (Figures 1 and 2), the column base member 40 (Figures 4C, 4D, 4E, 4J, 4L) that is adapted to receive first or second ends 41a, 41b of column hollow sections 24 (as each column hollow section is symmetric). Indeed, it is important to be mentioned that column hollow sections 24 forming columns 12a, 12b, 12c, 12d are identical and symmetric, so they are all configured to interface/interconnect with column base members 40a, 40b, 40c, 40d (which are also identical/symmetric). As shown more particularly in Figures 4C-4E, 4J, 4L, each column base member 40 includes a plate member 43 and a hollow base structure 45 which upwardly extends from plate member 43 when column base member 40 is positioned on the surface adjacent the building structure, with two sets of vertically aligned apertures 47 formed therethrough.

[0089] Therefore, when assembling a column hollow section 24 with a column base member 40, column base member 40 is positioned on a surface adjacent the building structure. First section end 41a of column hollow section 24 is introduced within hollow base structure 45 of column base member 40 and releasably secured introducing bolts within first and second sets of apertures 47 formed within hollow base structure 45 and further within the lower ones of the spaced apart openings 32 found in longitudinal grooves 30a, 30b, 30c, 30d (Figure 4L). A person skilled in the art to which common tower 10 pertains would however understand that other securing members and/or mechanisms may be used in a way to releasably secure a column hollow section end to a column base member 40 in a way to support each one of columns 12a, 12b, 12c, 12d.

[0090] Referring now more particularly to Figure 4K, column section-to section

connecting member 26 is then introduced within column hollow section 24 about at

its second end 41b in a way that outer surface 38 defined by hollow main body 34

interfaces with inner surface 27 defined by column hollow section 24. First/lower end

41a of an adjacent/upper column hollow section 24 is then positioned over column

section-to-section connecting member 26, until first/lower end 41a (or edge) of upper

column hollow section 24 interfaces with second/upper end 41b (or edge) of lower

column hollow section 24. Still referring to Figure 4K, height pin-like members 46 are

introduced in spaced apart openings 32 (formed within longitudinal grooves 30a,

30b, 30c, 30d) that are aligned with first set of apertures 36 (formed within hollow

main body 34), such as to secure upper and lower column hollow sections 24 to

(over) column section-to-section connecting member 26. It is important to be

mentioned that pin-like members 46 are linked by chains, steel wires or any other

connections, so that no connector may fall from tower 10 during/after its

erection/assembly (or during steps of assembling column hollow sections together).

An upper column section-to-section connecting member 26 (Figure 4I) is introduced

within upper column hollow section 24 about its second/upper end 41 b, as defined

above, and by aligning their respective column section axis 25 and connecting

member axis 29. Therefore, when columns 12a, 12b, 12c, 12d are assembled and

aligned together, column section-to-section connecting members 26 are concentric

with longitudinally aligned column hollow sections 24 that are longitudinally aligned

one over another (Figure 4E). The remaining column hollow sections for each

column 12a, 12b, 12c, 12d will be installed after one flooring structure, or

alternatively two flooring structure(s), is/are releasably and slidably supported by the

first two column hollow sections 24 of each column 12a, 12b, 12c, 12d. In other

words, one common tower floor may be assembled/erected at a time. Additionally, it

is to be mentioned that even if column base member 40 was described as firstly

connected with first/lower column hollow section 24, it is further possible to

releasably connect first/lower and second/upper column hollow sections 24 together

first, and then to secure lower end 41a of one of the two column hollow sections 24

with column base member 40.

[0091] Referring now more particularly to Figures 5A and 5B, as mentioned above,

tower 10 comprises a plurality of vertically spaced apart flooring structures (14a, 14b,

! 14c shown in Figures 1 and 2), referred to as 14 in Figures 5A and 5B. Indeed, Figures 5A and 5B illustrate flooring structure 14 that is releasably and slidably supported by and/or connected to spaced apart columns 12a, 12b, 12c, 12d. Flooring structure 14 shown in Figure 5A is illustrated in its lowermost position, while flooring structure 14 shown in Figure 5B is illustrated in its uppermost position.

[0092] Referring now more particularly to Figures 6A and 6B, there is shown that flooring structure 14 is made of four primary beam sections 48a, 48b, 48c, 48d, and a fifth primary beam section 48e, namely the primary landing beam sections, that will be, once slidably mounted on columns 12a, 12b, 12c, 12d, perpendicularly (48a, 48b, 48c, 48d) assembled one about another (in the scenario where four columns are provided). Each one of primary beam sections 48a, 48b, 48c, 48d, 48e defines a beam first end 50a, 50b, 50c, 50d, 50e and a beam second end 52a, 52b, 52c, 52d, 52e. Beam first ends 50a, 50b, 50c, 50d are adapted to releasably and slidably engage with a respective column 12a, 12b, 12c, 12d, while beam second ends 52a, 52b, 52c, 52d are adapted to releasably and slidably engage with an adjacent one of the spaced apart columns 12a, 12b, 12c, 12d. In other words, still referring to Figures 6A and 6B, ends 50a, 52d of primary beam sections 48a, 48d are adapted to releasably and slidably engage with column 12a, ends 52a, 50b of primary beam sections 48a, 48b are adapted to releasably and slidably engage with column 12b, ends 52b, 50c of primary beam sections 48b, 48c are adapted to releasably and slidably engage with column 12c and ends 52c, 50d of primary beam sections 48c, 48d are adapted to releasably and slidably engage with column 12d, thanks to sliding members 54a, 54b, 54c, 54d, 54e, 54f, 54g, 54h that will be described in more details below.

[0093] Now referring to Figures 8A-8E, there is shown that each primary beam section 48a, 48b, 48c, 48d is configured to be releasably and slidably connected to or supported by two adjacent columns 12a, 12b, 12c, 12d by releasably connecting a sliding member 54a, 54b, 54c, 54d, 54e, 54f, 54g, 54h to a beam first or second end 50a, 50b, 50c, 50d, 52a, 52b, 52c, 52d and by releasably and slidably connecting the sliding member to a column 12a, 12b, 12c, 12d. Indeed, each sliding member, referred to as sliding member 50 in Figures 8A-8E, comprises a sliding member main body 55 and a longitudinal sliding surface or elongated portion 56 extending from the sliding member main body 55. Longitudinal sliding surface or elongated portion 56 is configured to releasably and slidably engage with spaced apart longitudinal grooves 30a, 30b, 30c, 30d. A person skilled in the art to which tower 10 pertains would here understand that even if sliding surface or elongated portion 56 is shown to adopt a T- like shape, sliding surface or elongated portion 56 may adopt any cross-sectional size, shape and/or configuration, as long as it can be introduced in, and secured to, longitudinal grooves 30a, 30b, 30c, 30d of a column hollow section 24 in a downward or upward sliding movement relatively to columns 12a, 12b, 12c, 12d, such as to provide a strong connection between sliding member 54 and columns 12a, 12b, 12c or 12d when sliding member 54 is pulled away from its respective column (or alternatively pushed upward or downward within grooves 30a, 30b, 30c, 30d).

[0094] Still referring to Figures 8A-8E, sliding member main body 55 further defines a beam receiving groove 57 (opposite longitudinal sliding surface or portion 56), a sliding member first/upper end 58 and a sliding member second/lower end 60. Each sliding member 54 thus further comprises a first spring loaded pin 62 operatively mounted on sliding member main body 55 about sliding member upper end 58 and a second spring loaded pin 64 also operatively mounted on sliding member main body 55 about sliding member lower end 60. First and second spring loaded pins 62, 64 are adapted to engage with two of the spaced apart openings 32 formed within each one of the longitudinally aligned column hollow sections 24. Therefore, when first and second spring loaded pins 62, 64 are disengaged from longitudinally aligned column hollow sections 24 or columns 12a, 12b, 12c, 12d, primary beam sections 48a, 48b, 48c, 48d are capable of horizontal displacement relatively to spaced apart columns 12a, 12b, 12c, 12d. One may pull first or second spring loaded pin 62, 64 to disengage spring loaded pins 62, 64, or may turn it to lock in place. Height of each flooring structure relatively to the ground surface or to an adjacent flooring structure may thus be adjusted independently, so it is possible to make correspond the common tower floors with the building levels of the high-rise building into construction. Indeed, a penthouse, or a mechanical room, usually provided with high ceilings, for example, will require the distance between two adjacent common tower floors to be increased.

[0095] Still referring to Figures 8A-8E, each sliding member 54 further comprises spaced apart sliding member apertures 66 formed through beam receiving groove 57 of sliding member main body 55 (opposite longitudinal sliding surface or portion/connector 56), while primary beam sections 48a, 48b, 48c, 48d (illustrated as 48) each comprises corresponding spaced apart beam apertures 68 (Figure 8E) at their beam first and second ends (50a, 50b, 50c, 50d, 52a, 52b, 52c, 52d), in Figure 8E illustrated as 50. Therefore, additional pin-like members 70 are here used to releasably connect sliding member 54 with beam end 50 that is introduced within beam receiving groove 57. Pin-like members 70 are introduced within spaced apart sliding member apertures 66 and further within corresponding spaced apart beam apertures 68 that are aligned one with another, such as to provide a "beam-to-sliding member* assembly. It is further important to be mentioned that pin-like members 70 are fixed/secured to sliding member 54 using chains 71 or similar elements, and that first and second spring loaded pins 62, 64 are integrated into sliding member main body 55 so that security during installation is increased (no such connector can fall from tower 10 during or after its erection). It is further important to be mentioned that sliders 54 are symmetrically formed, so it can be oriented according to two different positions (spring loaded pin 62 above spring loaded pin 64, or below spring loaded pin 62, when installed on column/beam). Such symmetricity of the column hollow sections 26, but further of the sliding members 54, makes it easier to assemble components of tower 10 together.

[0096] Referring now more particularly to Figures 7A and 7B, there is shown that flooring structure 14 further comprises a plurality of secondary beam sections 72, namely the secondary landing beam sections, which are releasably connected to primary beam sections 48a, 48b, 48c, 48d, 48e (via connectors 73) in a way to secure the primary beam sections together before, during and after their releasable sliding connection with columns 12a, 12b, 12c, 12d. The secondary beam sections together with the primary beam sections (first and second landing beams) together form the deck supporting structure.

[0097] Now referring to Figures 9A and 9B, there is shown that each flooring structure 14 (here illustrated as comprising a main deck 49 and a secondary deck 51 or deck extension, that extends from primary deck 49) further comprises a plurality of spaced apart primary floor supporting elongated members 74, namely the primary ledger beams, which are configured to be releasably supported by, or mounted on, primary beam sections 48a, 48b, 48c, 48d, 48e or at least some of them (and further supported by secondary beam sections 72). Flooring structure 14 further comprises a plurality of spaced apart secondary floor supporting elongated members 76, namely the secondary leger beams, which are configured to be supported by, or mounted on, a primary beam section (48a) and perpendicularly and releasably connected to a primary floor supporting elongated member 74 (the one adjacent primary beam section 48a).

[0098] As better shown in Figures 9B, 9C and 9D, each primary/secondary floor supporting elongated member 74, 76 (Figure 9D) comprises a base member 80, a wall section 82 which upwardly extends from base member 80, and a top member 84 supported by (extending from) wall section 82. Top member 84 defines a top member longitudinal groove 86 which is adapted to receive an elongated wood strip 88. Flooring structure 14 therefore further comprises a plurality of pressure release connectors 90 (Figures 9B, 9D) that are adapted to releasably connect with respectively the primary floor supporting elongated members 74, the primary ledger beams, and the primary beam sections (48b, 48d, 48e) in order to releasably connect primary/secondary floor supporting elongated members 74, 76 to, or to mount them on, primary beam sections, and the secondary beam seconds 72. Indeed, referring to Figure 9B, there is shown that, for each primary floor supporting elongated member 74, two pressure release connectors 90 are releasably connected thereon (one at each end) so the primary/secondary floor supporting elongated members may be releasably connected to primary beam sections 48b, 48d, 48e.

[0099] Still referring to Figures 9A and 9B, there is shown that flooring structure 14 further comprises a plurality of flooring elements 78a, 78b that can be supported by or fixed (secured to) the primary and secondary floor supporting elongated members 74, 76. A first layer of flooring elements 78a such as, without limitation, wood planks, are fixedly or releasably secured (using nails, screws or the like) on a perpendicular manner on top of primary and secondary floor supporting elongated members 74, 76 by nailing or screwing flooring elements 78a onto elongated wood strips 88 that are introduced within top member longitudinal groove 86 of primary and secondary floor supporting elongated members 74, 76 (Figures 9C and 9D). A second layer of flooring elements 78b such as, without limitation, plywood sheets, are fixedly or releasably secured (using nails, screws or the like) on top of first layer of flooring elements 78a.

[00100] Still referring to Figures 9A and 9B, flooring structure 14 may include a main deck 49 and further a deck extension 51 that may be releasably connected to main deck 49. Main deck 49 will be responsible of regrouping/receiving the hoisting equipment, while deck extension 51 will be responsible of providing a bridge between main deck 49, receiving workers and materials, and the building structure itself.

[00101] Therefore, when assembling the components of flooring structure 14 together, sliding members 54a, 54b, 54c, 54d, 54e, 54f, 54g, 54h are releasably connected to their respective beam first and second ends 50a, 52a, 50b, 52b, 50c, 52c, 50d, 52d (Figures 6A and 6B), using pin-like members 70, as they are here used to releasably connect each sliding member 54 with a beam end 50 that is introduced within beam receiving groove 57 of sliding member 54 (Figure 8E). Pinlike members 70 are introduced within spaced apart sliding member apertures 66 and further within corresponding spaced apart beam apertures 68 that are aligned one with another.

[00102] As shown in Figures 7A and 7B, primary beam sections 48a, 48b, 48c,

48d, 48e (primary landing beams) are perpendicularly positioned one relatively to another so that the plurality of secondary beam sections 72 (secondary landing beams) may releasably connect the primary beam sections 48a, 48b, 48c, 48d, 48e together, via connectors 73, and maintain them in a perpendicular relationship one to another.

[00103] Now referring to Figures 9A and 9B, main deck 49, and alternatively main deck 49 and secondary deck 51 , via their primary floor supporting elongated members 74, are positioned over primary beam sections 48a, 48b, 48c, 48d, 48e that are releasably linked with secondary beam sections 72, so that primary floor supporting elongated members 74 are spaced apart and parallel one to another, but also perpendicular to primary beam sections 48b, 48d, 48e. Once base members 80 of all primary floor supporting elongated members 74 are releasably secured to primary beam sections (48b, 48d, 48e) and to secondary beam sections 72 using spaced apart pressure release connectors 90 (Figures 9B, 9D), main deck 49 and secondary deck 51 are strongly secured to the deck supporting structure, made of the primary beam sections 48a, 48b, 48c, 48, 48e, the secondary beam sections 72 and the connectors 73. Elongated wood strips 88 were prior inserted into top member longitudinal grooves 88 formed within top members 84 of primary and secondary floor supporting elongated members 76, 78, so that first and second layers of flooring elements 78a, 78b may be supported by primary and secondary floor supporting elongated members 74, 76. Indeed, flooring elements 78a such as, without limitation, wood planks, were fixedly or releasably (using nails, screws or the like) secured on a perpendicular manner on top of primary and secondary floor supporting elongated members 74, 76 by nailing or screwing wood planks onto elongated wood strips 88 introduced within longitudinal groove members 86 of primary and secondary floor supporting elongated members 74, 76. Plywood sheets 78b, for instance, may therefore be fixedely or releasably (using nails, screws or the like) secured on the wood planks. It is to be noted that a person skilled in the art to which the common tower assembly pertains would understand that flooring structure 14 may be assembled according to different steps order (1- providing the deck supporting structure using the landing beams; 2- mounting the ledger beams onto the landing beams; 3- fixing the flooring elements to the ledger beams vs. 1- providing the deck supporting structure using the landing beams; 2- fixing the flooring elements to the ledger beams; 3- mounting the ledger beams onto the landing beams).

[00104] Referring now to Figures 10A and 10B, once flooring structure 14 (or part of a flooring structure 14) is assembled for one common tower floor, a pair of sliding members 54a, 54b is installed, on each column 12a, 12b, 12c, 12d, by downwardly sliding longitudinal sliding surface or elongated portion 56 of sliding members 54a, 54b along longitudinal grooves 30a, 30b of column hollow section 24, sliding through grooves 30a, 30b (3" sliding adjustment for a main beam/sliding member assembly and for up to 6” adjustment for a sliding member/column hollow section assembly). Therefore, when first and second spring loaded pins 62, 64 of sliding members 54a, 54b are disengaged from longitudinally aligned column hollow section 24, primary beam sections 48a, 48b are capable of horizontal displacement within grooves 30a, 30b. One may turn them to lock sliding members 54a, 54b in place (one flooring is aligned with a corresponding building level).

[00105] Referring now more particularly to Figures 7A, 7B, 12, there is shown anchoring system 18 that is releasably connected to a primary beam section 48c. Anchoring system 18 is configured to be anchored with the wall of a building structure and comprises a set of main arms 92 that are independently pivotably and releasably connected to a first anchoring member 94, which is releasably mounted on primary beam section 48c. Main arms 92 each comprises a plurality of main arm sections 96, as well as an anchoring plate 98 pivotably extending from distal main arm sections 96. Anchoring plates 98 each define a set of apertures 100, so that fasteners may be used to anchor anchoring plates 98 to the wall of the building structure. Anchoring system 18 further includes a set of secondary arms 102 that are independently pivotably and releasably connected to second and third anchoring members 104, 106, which are also releasably mounted on primary beam section 48c, distant from first anchoring member 94. Secondary arms 102 each comprises a plurality of secondary arm sections, as well as an anchoring plate 108 pivotably extending from secondary arms 102. Anchoring plates 108 each defines a set of apertures 110, so that fasteners may be used to anchor anchoring plates 108 to the wall of the building structure. The tower structure may therefore be anchored to the wall of the building with multiple configurations tumbuckles (possible displacement of the system in the x, y, and z axis).

[00106] As mentioned above and referring now to Figures 1 , 2, 11 A, 11 B, 11C, and 12, tower 10 comprises protection structures 20a, 20b, 20c (or 20) that are releasably mounted on each flooring structure 14a, 14b, 14c (and/or slidably connected to columns 12a, 12b, 12c, 12d) so as to upwardly extend from the flooring structures. As better shown in Figures 11 A, 11 B, 11C, each protection structure 20 comprises protection walls 112a, 112b, 112c, 112d, 112e, 112f, 112g. Protection walls 112a, 112b, 112c, 112d, 112e, 112f, 112g each comprises a main frame 116 defining a plurality of horizontally oriented members 117 and a plurality of vertically oriented members 119. First and second opposite edges of each wall adjacent a column may be adapted to slidably engage with spaced apart secondary longitudinal grooves 31a, 31 b, 31c, 31 d of column hollow sections 24 by downwardly sliding first and second opposite edges along longitudinal grooves 31 a, 31 b, 31c, 31 d. Other connection possibilities between the protection walls and the columns and/or the flooring structure may be provided. For example, the protection wall may be releasably mounted directly on the flooring structure, so they upwardly extend from the flooring elements 78a, 78b. Protection walls 112a, 112b, 112c, 112d, 112e, 112f, 112g each further comprises a protection that is connected to the horizontally and vertically oriented members 117, 119, such as, without limitation, a protection mesh, glass or membrane (that is fixed to main frame 116). Also, as shown, main frame 116, for some protection walls (112c, 112d, 112e) defines one or more openings or doors 122a, 122b, 122c, 122d, 122e, 122f so that workers can have access to the building structure 125 via building access 123 (Figure 12). A sturdy protection may therefore protect the whole landing area, even around the extension deck. [00107] Referring now more particularly to Figure 12, according to its configuration, tower 10, once erected/assembled, enable installation of up to six hoisting machines 124a, 124b, 124c, 124d, 124e, 124f (such as transport platform, construction elevator and the like) of the same type on a single common tower structure, where all hoisting machines are able to share a single access point 123 to building structure 125, up to a 1500’ elevation.

[00108] According to its novel configuration and components, tower 10, once assembled, brings an improved solution for high-rise installation. Indeed, it enables multiple machines of the same type to be used together as part of the same installation. It further provides less openings on the building structure’s walls. The design of the plurality of components, namely, the spaced apart columns (and the column sections), the vertically spaced apart flooring structures (and their components, namely the sliders, the landing beams, the ledger beams, etc.), the anchoring system, the protection structure as well as the plurality of connectors, leads to a faster installation of the tower that requires less fasteners, thanks to, for example, the sliding members that releasably and slidably connect each one of the flooring structures to the spaced apart columns 12a, 12b, 12c, 12d, as well as to a faster installation. Tower 10 may further be erected/assembled by a reduced number of workers and machinery (tool-less erection), thanks to the light weighted components, mostly made of aluminum extruded components/parts. Indeed, one 6- feet column hollow section weights about 130 pounds (in comparison, a mast section used for prior art towers may weight up to about 400-500 pounds for a 5-feet section). Safer use and installation of the tower itself is further provided, thanks to easy to install protection structures or meshes (that are configured to be slidably and releasably, or alternatively mechanically, connected to the columns and/or the flooring structures) and to the chain retaining pins that prevent falling fasteners during and/or after installation of the tower onsite. Flexibility of the tower design are further provided.

[00109] Referring now more particularly to Figures 14A-14G and to Figures 15A-15C, there is shown a protection enclosure 130 that is designed to provide a safe erection of common tower 10. Indeed, protection enclosure 130 is configured to be releasably and slidably supported by spaced apart columns 12a, 12b, 12c, 12d, when erecting tower 10, before all flooring structures 14a, 14b, 14c, etc. (Figures 1 and 2) are releasably secured to spaced apart columns 12a, 12b, 12c, 12d. Protection enclosure 130 is capable of vertical displacement relatively to spaced apart columns 12a, 12b, 12c, 12d when supported by them, as it will be described

below, such as to securely assemble one common tower floor at a time.

[00110] Protection enclosure 130 comprises a protection enclosure main frame

132 which defines a plurality of access openings 146a, 146b, 148, 150. Indeed,

Figure 14A shows access openings 146a and 146b, where opening 146a relates to

an upper building access and opening 146b relates to a lower building access.

Furthermore, Figure 14C shows access opening 148, which relates to a material

access opening (such as to receive materials from hoisting equipment that will be

needed to assemble common tower 10). Figure 14C also shows access opening

150, which relates to a roll-up door access for a hoist car. As it will be described in

more details below, protection enclosure main frame 132 is configured to releasably

and slidably engage with spaced apart longitudinal grooves 30a, 30b, 30c, 30d i defined in column hollow sections 24.

[00111] Protection enclosure 130 further comprises a roofing structure 134

which extends from protection enclosure main frame 132, as well as a plurality of

lifting assemblies 136 (usually a number of lifting assemblies that corresponds to the

number of spaced apart columns is provided). Each lifting assembly 136 is

operatively coupled to protection enclosure main frame 132 and further to a

corresponding spaced apart column 12a, 12b, 12c or 12d.

[00112] Referring now more particularly to Figures 15A, 15B and 15C, each

lifting assembly 136 comprises an elongated jack 138 which defines a first jack end

137 and a second jack end 139. Assembly 136 further comprises an upper slider 140

connected to first jack end 137 and protection enclosure main frame 132 and further

adapted to releasably and slidably engage with spaced apart longitudinal grooves

30a, 30b, 30c, 30d. Assembly 136 further comprises a lower slider 142 connected to

second jack end 139 and further adapted to releasably and slidably engage with

spaced apart longitudinal grooves 30a, 30b, 30c, 30d. It is to be mentioned that

design of upper and lower sliders 140, 142 may look like design of above described

slider 54, as they all need to slidably interreact with same longitudinal grooves 30a,

30b, 30c. 30d. Upper and lower sliders 140, 142 may therefore include a portion

similar to longitudinal sliding surface 56 defined above. Upper and lower slider main

bodies will however slightly differ from sliding member main body defined above as

they need to interact with first and second jack ends 137, 139 of elongated jacks 138 or actuators instead of with main beam ends. Therefore, according to its configuration, when protection enclosure main frame 132 is supported by the spaced apart columns, via upper sliders 140, protection enclosure main frame 132 is capable of vertical displacement between a protection enclosure lower position (Figure 15A) and a protection enclosure upper position (Figure 15B), as lifting assemblies 136 may extend from a compressed position (Figure 15A) to an extended position (Figure 15B). Such vertical displacement provides to securely assemble/disassemble common tower 10 one floor at a time, as it will be described in more details below.

[00113] Indeed, Figures 16A-16E illustrate a method of erecting/assembling a common tower 10 using the common tower assembly described above, where protection enclosure 130 is releasably and slidably connected to the partly assembled spaced apart columns.

[00114] According to Figure 16A, convey or hoist car 156, slidably and operatively mounted on crane 164 adjacent common tower 10 being assembled, brings material on common tower floor 154 being constructed. Hoist car enclosure 160 is provided above hoist car main frame 158 and configured to receive such material that will help in assembling common tower 10. Two already installed common tower floors, linked to building levels 162a, 162b, are shown in Figure 16A (see common tower installed floor 152).

[00115] According to Figure 16B, protection enclosure 130 is moved along spaced apart columns while providing lifting assemblies in their extended position (until bottom of protection enclosure main frame reaches flooring structure) so it protects the common tower floor being constructed. Additional column hollow sections may be aligned with, and connected to, the already installed column hollow sections.

[00116] According to Figure 16C, as required, column hollow sections are aligned with, and connected to, the already installed column hollow sections.

[00117] According to Figure 16D, another deck supporting structure is releasably and slidably connected to the assembled column hollow sections forming the spaced apart columns, and further adjusted in height, so as it is possible to construct a new common tower floor.

[00118] According to Figure 16E, protection enclosure 130 is moved along spaced apart columns (until bottom of protection enclosure main frame reaches flooring structure) so it protects the common tower floor being constructed. Additional column hollow sections may be aligned with, and connected to, the already installed column hollow sections. Anchoring system may further be installed to engage with the building structure.

[00119] Protection enclosure 130 therefore allows to quickly and safely assembly/disassemble common tower 10, as it frames the common tower floor that is constructed, prior moving up to provide safe construction of an adjacent common tower floor.

[00120] While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made therein without departing from the essence of this disclosure. Such modifications are considered as possible variants comprised in the scope of the disclosure.
