Title:
KIT FOR CONSTRUCTING DRY-MOUNTED WALLS
Document Type and Number:
WIPO Patent Application WO/2019/106700
Kind Code:
A1
Abstract:
The novelty and the inventive step of this process for constructing walls start from the overpassing of the concept of self-supporting wall as a solid and compact structure. We create a "moving wall", a wall that"must" be able to move, so hindering earthquakes and major thrusts. We get this through the elimination of binders and locking joints, the positioning of the elements using the diamond configurations and the creation of grooves and pins which, when in place, never block the elements but, in case of thrusts, leave them free to move aligned with the axes of the wall, along a system of transversal planes created by the surrounding elements in diamond configuration, like cars on their rails, allowing the gravity to reposition each element at the center of the wedge created by the underlying elements at the end of the shakes.

Description:
DESCRIPTION

Field of Application

The field of constructions and masonry together with the field of construction toys are the main fields of application of this invention, but snot the only ones; from these fields terminology and examples are taken, with an explanatory and non restrictive aim.

The main objective of this invention is the creation of a kit for the construction of dry-mounted walls having an innovative modality of resistance to earthquakes,

loAnother innovative characteristic of this invention is the form of the modular element, which allows the easy and cheap creation of any single piece, making industrially profitable its production.

State of the art

The benefits of the dry-mounted self-standing walls assembled in a i5diamond configuration, that is the inclination at 45° of the internal faces of the elements from the horizontal plane, have already been disclosed by previous patents, mainly Patent Blair U.S.3238680 and Patent Henderson U.S.4429506, which illustrate in detail its benefits and advantages, such as the way to implement it on field. These patents have 20the main aims of facilitating and standardising the processes of construction and reducing their related problems. The solutions disclosed by these patents do not tackle directly the possibility of optimising the resistance of their products to earthquackes that could compromise their utilization and actually they provide indirectly to this problem the 25standard solution of blocking the elements once in place, by grouting the

1

SUBSTITUTE SHEETS (RULE 26) elements (Pat. Blair) or by creating male/female joints shaped in order to block completely any movement once definitely in place (Pat. Henderson).

The attempt of a solution has been done by me, filing the Italian patent srequest nr. 102017000002158, rejected because considered as lacking of novelty; this file identifies a possible innovation in joining the diamond configuration with a different sort of joints allowing the elements to move, but it remains in the generality of the assumption, without providing any concrete solution for granting the proper movement, and lowithout proposing the insertion of pins and groves into the internal faces of the elements, solution that is proposed now and of which the protection in claimed in this patent request.

Furthermore the complexity of all previous solutions makes expensive their industrial production and jeopardise their diffusion

is Presentation of the invention.

The core of the novelty and the inventive step of this process for constructing walls is the abandoning of the concept of self-supporting wall as a solid and compact structure.

We get this through the elimination of both the binders and the locking 2ojoints, the positioning of the elements using the diamond configuration and the creation into the elements of a system of grooves and pins which, when in place, do not block the elements but keep them free to move, in case of thrusts or quakes, always aligned with the axis of the wall, along the system of transversal planes created by the surrounding elements

2

SUBSTITUTE SHEETS (RULE 26) with the diamond configuration.

This transversal planes transform any sort of thrust, into an upwards transversal thrust, always hampered by the force of gravity and the weight of the structure; at the end of the stresses the force of gravity will 5reposition each element in its original position, at the center of the wedge created by the underlying elements, using the same transversal planes.

This actions of repositioning the elements along the transversal planes back to their original position utilising the force of gravity is part of the inventive step and it is not possible on horizontal planes and if elements loare locked.

In addition to creating an extremely ergonomic basic element, functional to the purpose and industrially reproducible, the novelty and inventive step of this process of drywall construction is found in the identification, definition and use of four conditions, all necessary and sufficient to lscreate what we could call a“moving wall”, a wall that“must” be able to move, to hinder the seismic shakes and the major thrusts in a way that has to be considered inventive and innovative in the process of building vertical walls.

These four conditions are:

201) the shape of the elements and their correct positioning,

2) the shape of the grooves and pins that, while avoiding the locking

3

SUBSTITUTE SHEETS (RULE 26) joints, maintain their function of guide,

3) the diamond configuration of the elements, which allows the creation of wedges and transverse planes and the consequent absence of horizontal planes, which are identified as a major problem to be avoided sin this construction technique,

4) the dry construction, free of binders and free of locking joints, which prevents the solid welding of the elements once in place, keeping them in a static equilibrium.

The result of this invention is a dry-mounted wall, assembled in a lodiamond configuration composed of modular elements, their related completion elements and the containment bars and pillars.

The modular element is a six faces parallelepiped having a squared or rhomboid basis; the height of the parallelepiped when positioned will be the thickness of the wall and its basis will constitute the two facades of isthe wall. In the diamond configuration the two diagonals of its basis are disposed vertically and horizontally. When in its final position the element has two external parallel faces placed vertically, two internal faces laying upwards and two internal faces laying downwards. Into two contiguous internal faces two pins are inserted per each face, disposed at 20the same height and at the same distance from their closest external face, simmetrically (FIG.1,2,7).

The two opposite contiguous internal faces have two grooves each, laying symmetrically in correspondence of the pins which are on the opposite faces (FIG.1,3 ,7, 8); starting from the edge in common between

4

SUBSTITUTE SHEETS (RULE 26) the two faces, these grooves run along the faces in parallel with the external face of the element, for its entire length (FIG.1,3) or just to the height of their matching pins (FIG.7,8); these grooves will always be slightly wider than the thickness of the forecasted pins, and slightly sdeeper than their height, in order not to block or stress or press or strain anyhow the pins when the elements are assembled in their final position of static equilibrium. The force of gravity and the friction between the elements in the diamond configuration will grant the stability of the wall; the pins, together with the friction between the opposite faces, will lohinder the thrusts avoiding the misalignment of the wall along the axis of the facade. When assembling the elements, both faces holding pins have to face upwards or both downwards and in the same way for all the elements of that wall. For technical reasons the number of pins, their shapes, materials and/or dimensions may vary, provided that the ^corresponding grooves are matching the selected pins.

These characteristics make the production of the elements extremely cheap: the initial form to be created is a plain six faces block, into which you just have to carve the grooves and to insert the pins. With many materials grooves may be already forecasted when preparing the mold 2oand, for materials such as concrete or conglomerates, pins may be replaced by metal bars inserted into the mold, having one extremity remaining external to form the pin and the internal part utilised to reinforce the concrete. When using materials such as wood, pins allow to reduce wastage due to the carving and increase the resistance of the male 25joint in front of thrusts and stresses; for wood, so much as for many

5

SUBSTITUTE SHEETS (RULE 26) other materials, a pin inserted in an element, even if the two of them are composed of different materials, provides a much higher endurance in front of thrusts and stresses than a pin carved from the same piece. The specific materials utilised for pins and for elements will determine 5dimensions, profile, shape, height and thickness of pins.

In the proposed sample, the modular element is a square basis block with dimensions 70x70x100 mm (millimiters), excluding pins; its volume is 490 cc (cubic centimeters), excluding the variations due to pins and grooves. The four internal faces measure 70x100 mm and 100 mm is at lothe same time the length of the basis of the internal faces, the length of the vertical section and the thickness of the element when in its correct position. The two external faces measure 70x70 mm, and their diagonals both are 70L/2, that is 98,9 mm, which can be considered as 100, because of the tolerances of materials; therefore vertical and horizontal lssections in place can be considered as 100x100mm. The volume of almost half a cubic decimeter and the 100x100mm section make easy many evaluations and rough calculations also for unskilled labor; due to the diamond configuration, any layer of elements will raise the wall by 50 mm and its 100 mm thickness can be increased by 50 mm a time, by 2oplacing aside entire elements or halves of them, alternately. The dry construction technique makes all these measures compatible with those of the constructions requiring mortars or binders, so allowing the utilisation of all the finishing, the tools and the accessories already in use in the construction sector.

25The squared basis, the element dimensions and the proportions between

6

SUBSTITUTE SHEETS (RULE 26) its parts may be varied in case of technical or aestetic needs.

Grooves are 10 mm large and their depth is 20 mm; any of them is 20 mm distant from its closest external face and 40 mm distant from the other groove. The external part of pins is 8 mm thick and 19 mm high. sApart from minimising the production costs, the form of these elements, the shape of their joints and the diamond configuration allow an innovative reaction of the structure to earthquakes.

In a compact construction quakes release their energies over the weakest points of the structure; in this kit of construction the wall does not hinder lothe shake as a compact ensamble: on the contrary, any single element remains free to move; the enormous earthquake forces are parcelled in vectors aligned to the form and the positioning of the elements and they discharge their forces on any single element, causing their movement. The dry building technique allows the pieces movement, and the specific isplay created by pins and grooves forces elements to slide like cars over their rails, uniquely in a direction aligned to the axis of the facade and trasversal to the ground due to the diamond composition, while the two parallel grooves minimise the possibility of swinging and the risk of misalignment of the single elements, which are forced to slide and climb 2oalong the planes created by the contiguous elements, transforming all the strains into transversal and ascensional thrusts always hindered by the force of gravity that, at the end of the quakes, will reposition any single element at the center of its wedge in the diamond composition, bringing back the entire structure in the original position of static equilibrium. 25The downwards positioning of pins and the upwards positioning of

7

SUBSTITUTE SHEETS (RULE 26) grooves contribute to lower the barycenter of the element and help its balance during movements. The weight of the structure, the undulatory and discontinuous nature of the shakes and the continuous detachments of any single element from at least one of the contiguous ones, will tend sto parcel and hinder constantly the effects of the thrusts and the wall will react to eartquakes in a way which is much more similar to the reaction of gravel terrains than the reaction of the compact ones, dispersing the forces instead of discharging them against the weakest points.

Apart from the eartquakes, in which forces and thrusts are exceptional, lothe wall will maintain all the characteristics of static equilibrium and stability given by the dry-mounted building with diamond configuration already illustrated in the previous patents.

Finishing elements: being the modular elements set in a diamond configuration, finishing elements are junction elements connecting them i5to the basement (FIG 4), to lateral pillars (FIG 5) and with the top of the wall or the ceiling (FIG 6); they are also used to create doors, windows or technical holes for cabling or plumbing; they are obtained by dividing the modular element along one or more of its axes; their use is of immediate understanding (FIG 9-10-11). The section in two halves along 20the plane parallel to the external face results in two symmetrical pieces that can be use to enlarge the thickness of the walls by multiples of 50 mm. These finishing elements may have additional pins along the faces obtained by the splitting, allowing the anchoring to the facing elements (FIG 5), or allowing to satisfy technical needs (FIG 9-11).

25Containment elements: they are poligonal pillars into which other

8

SUBSTITUTE SHEETS (RULE 26) elements can be anchored or leant: differently from the rest of the construction, they can be fastened to the ground or to the basement; one or more lateral faces have male or female joints matching those of the elements used. In case of grooves, they will run vertically and they are sintended to transform the transversal thrusts into vertical ones allowing the finishing elements to make a vertical sliding movement which will lift the element, avoiding the possibility of being crashed by other elements, uplifting its contiguous elements up words and so discharging its lateral thrusts. As closing elements, U shaped bars can be used, lohaving joints or not; these bars have been already illustrated and they are part of the state of the art.

Many variants of the modular elements can be forecasted, such as two different elements, one with all male joints and one with all female joints, to be laid alternately, or having other variants with more than two lsdifferent elements having different shapes, creating different configuration with the same sort of joints, grooves and pins and without horizontal planes, always allowing any element to move, remaining within the perimeter of the invention.

Dimensions, colors, the sort of material utilized, the fact of being 2ointernally empty or compact or having any sort of holes, cavities or canalizations, the fact of being homogeneous or stratified or composed by one or more materials, all these are irrelevant details for the functionality of the process over which we claim the protection of the patent and may vary as per the needs or the requests.

25AII the elements utilized in the work should have dimensions,

9

SUBSTITUTE SHEETS (RULE 26) proportions, faces, joints, contact faces and profiles that must be compatible and matching with the modular element utilized; therefore for any modular element“A”, it will be necessary to create a“Type A” set of finishing elements having all the requested characteristics 5compatible with “A”. In future the development of this building technique will multiply the possible variety of elements, designed to solve specific problems or aesthetic necessities, always remaining in the perimeter of the invention.

As per what we have explained until here, it seems evident that the loprocess reaches its goals. The means of the process may have innumerable variations, all within the border and the perimeter of the invention and included into the attached claims. Any detail can be changed with other elements technically equivalent and materials will be diversified as per the local needs without going out of the protection of isthe requested patent. Even if elements are described referring specifically to the attached figures, the figures themselves and the reference numbers used in the description and in claims have to be solely intended as mere means for better understanding the process and they are not intended to put any limit to the protection claimed with the requested 2opatent.
