Description:
SCAFFOLDING SYSTEM FOR USE WITH CURVILINEAR WALLS AND METHOD

OF USE

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The priority of U.S. Provisional Patent Application No. 62/450,375 for "Integrated Modular Scaffolding System," filed January 25, 2017, is hereby claimed and the specification thereof is incorporated herein by reference.

FIELD OF THE DISCLOSURE

[0002] The present disclosure generally relates to systems and methods for scaffolding systems for use with curvilinear walls. More particularly, the present disclosure relates to scaffolding which fits about the curved wall of a holding tank and which can be readily moved to varying heights of the holding talk wall.

BACKGROUND

[0003] Scaffolding systems, or staging, are well known, originating in ancient times. It provides a temporary structure of sufficient strength to safely support workers at elevated heights in construction and repair. The use of horizontally-aligned lateral support members and longitudinal work surfaces arose during ancient times. At the beginning of the 20th century, changes included the use of mechanical means to maintain the scaffolding parts in position, particularly the development of the Universal Coupler, the use of tubular steel pipes instead of wooden poles, the standardization of scaffolding dimensions, and the use of diagonal bracings. Scaffolding today uses those couplers, in connection with tubes and boards, to provide a rectilinear structure which abuts a rectilinear wall.

[0004] Traditional scaffolding systems, however, are not well-suited for use in connection with curvilinear surfaces, such as buildings, whose surfaces are curved for architectural aesthetics, and storage tanks, whose surfaces are curved to address the internal pressures and avoid stress concentrations. While traditional scaffolding can be positioned adjacent the entirety of the work surface of a rectilinear wall, traditional scaffolding provides, at best, a point of tangency with a curvilinear surface, and increasing gaps along the scaffolding surface thereafter between the work surface and the boards.

[0005] Standard components to address a curvilinear wall are not commercially available. There are no "off the shelf reusable scaffolding systems, particularly for use with the erection of storage tanks and their curved planes. Instead, a custom fabricated plate scaffold must be constructed, which is job specific and which thereafter is scrapped or must be reconstructed with modifications for the next use. In such systems, the gap between the work surface and the boards is reduced by the use of shorter traditional boards and a shorter support structure, but such a system becomes cumbersome as the number of components increase and is limited to a particular radius. It is also known that the scaffolding may be somewhat fitted about a curvilinear surface by the use of planks which are pivotally attached to one another, which still provides a point of tangency and increasing gaps on each side thereof. Such gapping provides unsafe work conditions.

[0006] Traditional board and bracket tank building systems are antiquated, labor intensive, and unsafe in light of today's safety standards. The currently available scaffolding systems for concrete wall tank construction are heavy, burdensome, and cannot be replicated on the metal tank side of a double wall containment tank. The resulting gaps between board and wall permit dropped objects to fall below the work surface and potentially onto those below. The workspace is often further cluttered with the supporting hoses and power cables for tools used, as well as the tools themselves, all of which are positioned on the boards of the scaffolding systems. Moreover, repositioning of such scaffolding may require complete disassembly, repositioning, and reassembly, requiring substantial manpower and resulting in downtime.

Preferably the first decking body 104 is a box of welded metal of a thickness sufficient to support workers, such as 0.125 inch (3.175 mm) ASTM A36 steel. The first decking body 104 may include a first decking body reinforcement 132, extending from the first decking body third edge 118 to the first decking body fourth edge 210, to support the first decking body top surface 202 and provide reinforcement for the receiver 204.

[0030] The first decking 102 has a receiver 204 in the first decking body top surface 202 on the first decking central axis 110 sized to receive the first decking extension plate capture member 130 which is downwardly dependent and preferably does not extend above the first decking top surface 202. The receiver 204, which may be circular to permit varied alignment upon installation, is aligned to the first decking body central axis 110. The receiver 204 is positioned and sized to align with and retain the first decking extension plate capture member 130 from a second, adjacent first decking 102, while permitting the two first decking bodies to be unaligned on a first decking central axis 110, permitting the succession of first deckings 102 to provide a non-linear profile.

[0031] The first decking first capture member 106 is affixed to the first decking body 104 intermediate the first decking body first edge 114 and the first decking body central axis 110 at the first decking body bottom surface 120 at the first decking body lateral axis 112 while the second decking second capture member 108 is affixed to the first decking body 104 intermediate the first decking body second edge 116 and the first decking body central axis 110 at the first decking body bottom surface 120 at the first decking body lateral axis 112.

However, the first decking extension plate 124 may present other profiles, such as a trapezoid or rounded rectangular.

[0032] The first decking extension plate capture member 130 is affixed at the first decking extension plate bottom surface 128 to the first decking extension plate 124 on the first decking extension central axis 126.

[0033] A first decking first attachment member 190 and a first decking second attachment member 192 may be affixed to each first decking 102 at the first decking body bottom surface 120 and adjacent the first decking body first edge 114 and the first decking body second edge 116, respectively, and descend downwardly from the first decking body 104.

The attachment member receiver 804 may include a capture member retention pin 806, which passes through the attachment member 190, 192, 490, 492, 690, 692, and is maintained in position by a nut, lock or pin 808. Adjacent the attachment member receiver 804 in the base 802 may be a handrail support 810, over which, or into which, the handrail stanchion may fit.

[0041] Referring to FIG. 9, a double truss 902, a telescoping longitudinal support member, for the present disclosure is provided. The double truss 902 may be of an initial width 904 at a first end in a box and may be extendable at its first and second ends 906, 908 with telescoping members 910, 912, as well as extendable laterally with lateral telescoping member 916

[0042] Each double truss 902 may further include a friction clamp 950 or other mechanism to fix the telescoping member 910, 912 in relation to the balance of the double trusses 902 to prevent further telescoping after installation, such as by constricting the outer body of the double truss 902 about the telescoping member 910, 912. Other systems, such as pins, may also be used. When engaged, the friction clamp 950 prevents a change in the position of any lateral support member attached to the double truss 902 and any change in position of any first decking 102

[0043] Referring to FIG 1, so that the first decking 102 and second decking 302 may be maintained in positioned on the double truss 902, the first decking first capture member 106 and the first decking second capture member 108 may be comprised of an opening in the first decking body 104 to which truss retention clips may be affixed, or may be brackets which affix, such as by bolting, about the double truss 902 and to the first decking body 104, or may be a U- bolt. The first decking first capture member 106 and second decking second capture member 108 may thus tie the first decking body 104 to the underlying double truss 902, preferably so the components form and integral whole resisting lateral movement of the first decking body 104 and permitting the first decking body 104 and underlying double truss 902 to be moved upward as a whole. The capture member distance 122 may be sized to ensure attachment to the underlying double truss truss 902. The capture member distance 122 is adjustable, to permit the first decking first capture member 106 and the second decking second capture member 108 to tie the first decking body 104 to the double truss 902, while accommodating the variance in the capture distance 122 resulting from increasing deviations on a curvilinear profile.

[0044] Referring to FIG. 10, to accommodate the varying radii, the resultant rotation of the first decking 102, and the associated differences in length on the inside and outside of any wall, two independent longitudinal support members, two single trusses 1002, rather than the double truss 902 may be used. The single trusses 1002 may be extendable at each of their first and second ends 1006, 1008 with telescoping members 1010, 1012.

[0045] Referring to FIGS. 9 and 10, further improvements may be provided by providing the longitudinal support members, trusses 902, 1002, may be sized to the appropriate length to obtain the desired arc length. Each truss 902, 1002 may further include a friction clamp 950 or other mechanism to fix the telescoping member 910, 912 in relation to the balance of the trusses 902, 1002 to prevent further telescoping after installation, such as by constricting the outer body of the trusses 902, 1002 about the telescoping member 910, 912. Other systems, such as pins, may also be used.

[0046] Referring to FIG. 11, a further improvement may be provided by provision of a telescoping lateral support member 1102. While each lateral support member 1102 may be constructed as a box it may be constructed to include a horizontal support 1154 and a knee brace 1156. Construction of each lateral support member 1102 to include a knee brace 1156 permits each lateral support member 1102 to be attached to the adjacent wall, such that the knee brace 1156 contacts a lower portion of the adjacent wall and thus maintains the telescoping lateral support member 1102 in position.

[0047] Referring to FIGS. 9, 10 and 11, preferably two lateral support members 1102, each with a particularly knee brace 1156, may be provided at each end 914, 1014 of a truss 902, 1002 where each lateral support member 1102 is telescoped to fit about the first decking 102 when positioned on the truss 902, 1002. Each lateral support member 1102 may provide a locking surface 1104 to which the truss 902, 1002 may lock, and therefore become attached to the lateral support member 1102, rendering the two components an integral whole and thus preventing any independent movement in the vertical plane between the two components. This may be dual- flanged surface 1106 which provides an upper flange 1109 at its top 1108 and the lower surface 1111 at its bottom 1110 to mate to a locking mechanism 1050 at the end 914, 1014 of each truss 902, 1002, or may be other systems known in the art, such as a pin and connector, which capture the lateral support member and make it integral. Such a locking mechanism 1050 may include an upper jaw 1052 sized to engage the upper flange 1109 when lowered into position and include an adjustable lower jaw 1054 to engage the lower surface 1111, thereby tying the truss 902, 1002 and the lateral support member 1102 together. The lateral support member 1102 may include two connecting points 1112 at the first end 1114 and the second end 1116 positioned above the top surface of the first decking 102 when installed. The lateral support member 1102 therefore has a lateral support member width 1118 greater than the first decking body width 140. The lateral support member 1102 may be constructed to provide a telescoping support rail 1120 and a receiver 1122, which may be retained in relation to one another by systems known in the art, such as a pin 1126. The telescoping support rail 1120 is fitted telescopically to a receiver 1122. The relative positions of the telescoping support rail 1120 and a receiver 1122 may be adjusted to accommodate the effective width of the first decking 102. The truss 902, 1002 may be deployed from one lateral support member 1102 to another and telescoped to address the distance between each of the lateral support member 1102.

[0048] Referring to FIG. 12, each lateral support member 1102 may be constructed to hang from a wall-mounted drop-in connector 1202. Such a connector 1202 may be affixed to the wall surface and may be directional, such that the lateral support member 1102 may be lowered onto the connector 1202 and, by virtue of the knee brace 1156, fully engages the wall surface and transfer all loads to the wall. As a result, the lateral support member 1102 is attached to the adjacent wall, such that the knee brace 1156 contacts a lower portion of the adjacent wall and thus maintains the telescoping lateral support member 1102 in position.

[0049] Referring to FIG. 13, an assemblage of components in the scaffolding system is illustrated with handrails and other equipment. The lateral support members 1102 are provided and serve as the point of attachment for the trusses 902, 1002. The trusses 902, 1002 may be sized to the appropriate length to obtain the desired arc length and by providing lateral support members 1102 which may be telescoped to the appropriate distance to accommodate the deflection of the first decking 102 necessary to fit the radius of the adjacent structure. The relative positions of the telescoping support rail 1120 and a receiver 1122 may be adjusted to accommodate the effective width of the first decking 102 as the system 1350 abuts a surface which may be non-linear. The handrail stanchion 1302 may be affixed to each attachment member receiver 804 and may provide a support for further component for safety or ease of operation. To each handrail stanchion 1302 may be mounted a top rail 1304, which preferably includes a telescoping end 1306 to accommodate the varying distance of the system 1350 at its outer edges. A mid rail 1316 may be likewise provided which also provides an adjustable length. Similarly, an integrated toe board 1308 may be provided with incorporates the rigidity of a mid rail 1316, such as by an angled in metal worksurface. Further, a bottom rail with a toe board may be provided. Gates, netting, and other safety equipment known in the art may likewise be attached to the handrail stanchions 1302 and/or to the top rail 1304 or other hand rails, or to the trusses 902, 1002, so as to be fixedly attached to the system 1350 without interfering with the workspace and while permitting the entire system 1350 to be moved as an integral whole. Similarly, other equipment, such as air hose reels 1310, electrical conduit, water jugs 1314, and toolboxes 1312, may be mounted external with work area above the first decking 102 for ease of access and elimination of workspace clutter. Such mounting may be accomplished by clips mounts sized to the rails, stanchions or trusses or by other mounting systems known in the art.

[0050] As the wall-mounted drop-in connector is directional, the system 1350 may be lifted an an integral unit at the two connecting points 1112. Beneficially, when trusses 902, 1002 are locked to at each end to a lateral support member 1102, and each of lateral support member 1102 are constructed to hang from and contact a wall-mounted drop-in connector 1202 as a temporary, directional attachment or hanger, such as by a lateral support hanger 1124, then the system 1350, including the first deckings 102, any intermediate deckings 602 and the end deckings 402 positioned between a first lateral support member 1102 and a second lateral support member 1102 (which may include one or more lateral support members 1102 intermediate), may be lifted as a unit by connection of lifting cables to the connecting points 1112 to a higher elevation where a further set of connecting points 1112 may be positioned. When engaged, the friction clamp 950 prevents a change in the position of any lateral support member attached to the truss 902 during relocation of the system 1350 and any change in position of any first decking 102. The system 1350 thus may serve as the main methodology for erection of walled constructions having curvilinear surfaces, particular storage tanks, may be attached to steel surfaces and may be integrated into formwork systems to provide work platforms on curved surfaces.

Method Description

[0051] Referring now to FIG. 14, a flow diagram illustrates one embodiment of a method 1400 for implementing the present disclosure. The method 1400 is performed during construction operations. [0052] In step 1402, a plurality of wall-mounted drop-in connectors 1202 are affixed to a wall.

[0053] In step 1404, each of a plurality of lateral support members 1102, each having a horizontal support 1154 and two locking surfaces 1104, is each lowered to engage, and be maintained in position, by one of the wall-mounted drop-in connectors 1202 at a lateral support hanger 1124. The lateral support member 1102 also includes a connecting point 1112 at each of the first end 1114 and the second end 1116 positioned above the top surface of the first decking 102 when installed.

[0054] In step 1406, a longitudinal support member 1002 is attached at each end 906, 908 to one of the plurality of lateral support members 1102. The longitudinal support member 1002 may have telescoping members 910, 912 at one or both of its first end 906 and second end 908 and a locking mechanism to engage the locking surfaces 1104 of the lateral support member 1102

[0055] In step 1408, a second longitudinal support member 1002 is attached at each end 906, 908 to one of the plurality of lateral support members 1102.

[0058] In step 1414, a first decking 102, is positioned atop the longitudinal support member 1002 and the second longitudinal support member 1002 such that the first decking extension plate capture member 130 is retained by the end decking receiver 428. The first decking body 104 has a first decking first capture member 106 and a first decking second capture member 108, and a receiver 204.

[0059] In step 1416, the first decking 102 is coupled to the longitudinal support member 1002 by the first decking first capture member 106 and to the second longitudinal support member 1002 by the first decking second capture member 108.

[0060] In step 1418, each of a plurality of support lines is attached to each of the connecting points 1112 of the each of a plurality of lateral support members 1102.

[0061] In step 1420, a second plurality of wall-mounted drop-in connectors 1202 are affixed to the wall. The second plurality of wall-mounted drop-in connectors 1202 may be laterally adjacent the plurality of wall-mounted drop-in connectors 1202 or may be above or below the plurality of wall-mounted drop-in connectors 1202.

[0062] In step 1422, each of the plurality of lateral support members 1102 is lifted vertically by the plurality of support lines attached at each of the connecting points 1112 of the each of a plurality of lateral support members 1102 to disengage from the wall-mounted drop-in connectors 1202.

[0063] In step 1424, each of the plurality of lateral support members 1102 are relocated to a position above the second plurality of wall-mounted drop-in connectors 1202.

[0064] In step 1426, each of the plurality of lateral support members 1102 is lowered vertically by the plurality of support lines attached at each of the connecting points 1112 of the each of a plurality of lateral support members 1102 to engage from the second wall-mounted drop-in connectors 1202.

[0065] While the present disclosure has been described in connection with presently preferred embodiments, it will be understood by those skilled in the art that it is not intended to limit the disclosure to those embodiments. It is therefore, contemplated that various alternative embodiments and modifications may be made to the disclosed embodiments without departing from the spirit and scope of the disclosure defined by the appended claims and equivalents thereof.
