?Bearing structure for a wall panel?

DESCRIPTION

Technical field

The present invention ? relating to a load-bearing structure for a wall panel, in particular for the construction of dry prefabricated buildings, cio? without the need for the use of binders such as cement mortars, resins and the like.

This load-bearing structure for a wall panel is used in the building sector, in particular in the production of components for prefabricated buildings and building organisms in general

State of the art

Time ago ? note the building prefabrication, cio? the construction process of buildings by means of elements made, at pi? work or in industry, and then assembled with highly codified procedures.

This mode? of construction of buildings allows to speed up the process of construction of building structures, anticipating part of the operations that are traditionally carried out on site.

? It is therefore evident that the prefabrication of the building allows to obtain higher speeds? of construction and fewer uncertainties in construction times compared to traditional building site construction techniques.

Typically, building prefabrication takes place through the industrial construction of individual building components, such as beams, pillars, trusses, closing panels and the like, which are then assembled on site using hydraulic binders to form the load-bearing and closing framework of the building.

The prefabricated construction elements require finishing interventions, at most? of work, suitable for adapting the prefabricated construction element to the particular building under construction.

For example, in the state of the art ? the use of prefabricated panels for the construction of walls is known.

These panels, typically rectangular in shape, are of the multilayer sandwich type, ie? include a plurality of layers, of different materials, capable of cooperating to guarantee the desired mechanical resistance, acoustic and thermal insulation.

In detail, these prefabricated panels have a perimetric edge suitable for abutting against the perimetric edge of other panels, adjacent to them, to define a wall of a building.

However, before installation, these prefabricated panels require finishing operations so that they can they can be correctly laid and blocked on the appropriate structural support elements, such as beams and columns.

Disadvantageously, these finishing and preparation operations for laying the prefabricated panels increase construction times on site.

Furthermore, disadvantageously, the finishing operations increase the uncertainty of execution times since, like all operations on site, they are subject to delays.

Furthermore, disadvantageously, these prefabricated panels are not configured to interact mechanically with the other elements of the prefabricated building to increase their non-deformability, as they are simply glued to the load-bearing structure by means of adhesives such as cement mortars, resins and the like

Purpose of the invention

In this context, the task of the technician at the basis of the present invention is propose a load-bearing structure for a wall panel and a related wall panel which overcome the drawbacks of the prior art mentioned above.

In particular, ? The object of the present invention is to provide a load-bearing structure for a wall panel and a wall panel for prefabricated buildings which is both quick and easy to install, i.e. that does not require finishing operations and preparation for installation on site.

Furthermore, ? object of the present invention to make available a wall panel configured to interact with the other structural elements of the building in order to increase the non-deformability? and the mechanical performance of the building.

SUMMARY OF THE INVENTION

The technical task specified and the aims specified are substantially achieved by a load-bearing structure for a wall panel and by a wall panel which overcomes the drawbacks of the known art mentioned above.

In particular, the bearing structure object of the present invention has an upper edge, a lower edge, and a pair of lateral edges.

This bearing structure comprises a lower profile defining the lower edge, and an upper profile defining the upper edge; wherein, each profile extends between the pair of side edges.

Furthermore, the bearing structure object of the present invention comprises a pair of tubular bodies parallel to the lateral edges but not coinciding with them.

? object of the present invention is also a wall panel comprising a plurality? of layers presenting properties? thermal and/or acoustic insulators, and the aforementioned load-bearing structure.

In detail, the supporting structure? integrated between the plurality? of layers of the wall panel, that is? ? placed between them.

Advantageously, the lower and upper profile are configured to interact and be connected with other structural elements of the building, thus that in the building site the load-bearing structure and the wall panel that includes it can be directly installed on the building under construction, without the need for? of any finishing or gluing operation.

Furthermore, advantageously, the pair of tubular bodies, thanks to their hollow conformation, allows to accommodate reinforcing elements suitable for connecting the load-bearing structure and the relative wall panel to a structural element of the floor and/or to a load-bearing element of a building, doing what? collaborate the various elements of the building by raising its non-deformability? and mechanical performance.

These prefabricated buildings 1 comprise a plurality of 3000 load-bearing beams interconnected to create the load-bearing framework. As shown in figure 13, at least part of these load-bearing beams 3000 are arranged parallel to a support plane 1a of the prefabricated building 1.

The prefabricated building 1 comprises at least one structural floor element 100 configured to be arranged on at least one pair of load-bearing beams 3000, oriented parallel to the support plane 1a, to define at least part of the floor of a prefabricated building 1.

In particular, the structural element of the floor 100 ? configured to be placed between at least two load-bearing beams 3000 so as to be at least partially embedded between the latter, as shown in figure 13.

With reference to figures 1 - 4, the structural element of the floor 100 comprises a frame 110 configured to abut against the load-bearing beams 3000 to support the structural element of the floor 100.

Preferably, but not necessarily, this frame 110 ? made of metal material, more? preferably in steel, or in aluminium.

Furthermore, the floor structural element 100 has a seat 120 extending between an upper plane S and a lower plane I parallel to each other. Seat 120 ? configured to accommodate one or more? layers 130 of a floor.

As shown in figure 1, the frame 110 is arranged around the perimeter with respect to the seat 120, that is? the frame 110 surrounds the seat 120 limiting it laterally.

Preferably, the frame 110 comprises a plurality of of sides L interconnected and delimiting the perimeter of seat 120. Even more? preferably, the frame 110 comprises four sides L, optionally parallel in pairs, i.e. has a quadrangular shape. Consequently, the seat 120 delimited laterally by the frame defines a volume in the shape of a parallelepiped which is usually quadrangular but potentially with a plurality of of sides and angles within which one or more are available? layers 130 constituting the floor.

With particular reference to figure 3, it should be noted that the frame 110 comprises a first flange 111 projecting into the seat 120 and lying in the lower plane I. In other words, the first flange 111 extends inside the seat 120 in correspondence with the lower plane I by making a cantilevered shelf capable of receiving one or more supports layers 130 of the floor, as shown in figure 4. The first flange 111 is configured then to support one or more? floor layers 130 which are inserted in the seat 120.

The frame 110 also comprises a second flange 112 which projects outside the seat 120, i.e. in the opposite direction with respect to the first flange 111. The second flange 112 ? configured to rest on at least one load-bearing beam 3000 to support the structural element of the floor 100.

? it is therefore evident that the floor structural element 100, by means of the first and second flanges 111, 112, allows to contain and support one or more? layers of the attic.

With reference to figure 3, preferably, the second flange 112 lies in the upper plane S, so that when it abuts against the support beam 3000, the structural element of the floor 100 is completely recessed. This allows you to reduce the thickness of the floor of the prefabricated building, in such a way as to arrange one more? slab layers between the supporting beams 3000.

Again with reference to figure 3, the frame preferably has an S-shaped section; that is? it has the main portion 110a extending between the lower I and upper plane S connecting the first and second flanges 111, 112 which project from the main portion 110a in opposite directions.

With reference to figure 1, preferably, the first flange 111 comprises a plurality of portions of first flange 111a, each of which ? associated with a respective side L of the frame 110. In other words, the plurality? of first flange portions 111a perimetrically surround the seat 120. The first flange portions 111a are configured to come into contact simultaneously with one or more? layers 130 of the floor to support them stably and arrange them inside the seat 120.

Furthermore, preferably, the second flange 112 comprises a plurality of of portions of second flange 112a, each of which ? associated with a respective side L of the frame 110. In other words, the plurality? of portions of the second flange 112a surround the seat 120 perimetrically. The portions of the second flange 112a are configured to abut against respective load-bearing beams 3000 to stably support the structural element of the floor 100 and fix it firmly to the load-bearing framework of the prefabricated building 1.

Preferably, the floor structural element 100 comprises first stiffening means 140 suitable for increasing its mechanical performance, in particular its stiffness and non-deformability. In detail, as shown in Figure 1, the first stiffening means 140 are configured to connect two contiguous sides L of the frame 110, i.e. two adjacent sides L having a common end.

In greater detail, the first stiffening means 140 comprise a plurality of of plates 141 connected to the frame 110. In particular, each plate ? arranged on the lower floor I and ? connected to two respective adjacent sides L of the frame 110. Even more? in detail, each plate ? triangular in shape and has a pair of legs respectively integrally connected to portions of the first flange 111a associated with adjacent sides of the frame 110.

Preferably, moreover, the floor structural element 100 comprises second stiffening means 150 capable of further increasing its mechanical performance. In particular, the second stiffening means 150 are configured to increase the load capacity of the floor structural element 100, i.e. the maximum load that ? able to hold. In detail, as shown in figures 1 and 2, the second stiffening means 150 are configured to connect two sides L of the frame 110 arranged on opposite sides of the seat 120. Preferably, the sides L connected by the second stiffening means 150 are parallel.

It should be noted that the second stiffening means 150 comprise a plurality of bars 151 arranged in the seat 120 and extending between two opposite sides L of the frame 110. In greater detail, each bar 151 has a pair of ends 151a connected to respective opposite sides L of the frame. Preferably, the extremities? 151a of each rod are integrally connected to respective portions of the first flange 111a associated with opposite sides L of the frame 110a.

Preferably, in accordance with what is shown in figure 1, the bars 151 are arranged parallel to each other and equidistant. even more preferably the bars 151 are arranged parallel to a side L of the frame 110. It should be noted that the greater ? the capacity of the structural element of the floor 100 desired, the greater it will be? the number of bars 151 necessary, and consequently less sar? the spatial spacing between one bar 151 and another.

Preferably, the floor structural element 100 comprises an anchoring element 160 connected to the second flange 112 and projecting from the upper plane S on the opposite side with respect to the lower plane I. This anchoring element 160 is? configured to mate with a prefabricated 2000 wall panel. More details on the wall panel 2000 and on the connection with the structural member of the floor 100 will be provided in a later part of the description.

With reference to figures 1-3, the anchoring element 160 extends mainly along a respective side L of the frame 110 and ? fixed to the respective portion of the second flange 112a. Preferably, the anchor element 160 is integrally connected to the respective portion of the second flange 112a.

The insertion section 165a has an extension perpendicular to the prevailing direction P-P of the opening 165 which is larger than the blocking section 165b. Therefore, the insertion portion 165a has a cross section greater than that of the locking portion 165b, to allow insertion inside the opening 165 of the reinforcing element 300.

even more preferably, the insertion portion 165a and the locking portion 165b are arranged in series along the prevailing development direction P-P and connected to each other. In this way, when the reinforcing element 300 ? inserted into the insertion portion 165a of the opening 165 and subsequently translated along the prevalent development direction P-P within the locking portion, it results constrained along a direction orthogonal to the surface S, given the smaller cross-section of the locking portion 165b.

In other words, preferably the wall panel 2000 ? predominantly rectangular but pu? assume a different shape if the edges 201, 202 and 203 do not extend parallel to the horizontal O-O and vertical V-V direction. So, the wall panel 2000 can? take on different geometric shapes with 3 or more? sides.

Such wall panel 2000 comprises a plurality of of layers 2100 presenting properties? thermal and/or acoustic insulators arranged between the pair of surfaces 204.

It should be noted that the sector technician ? able to select the number and material of the plurality? of 2100 layers of the panel according to the technical design characteristics of the prefabricated building 1. Examples of materials used to make the plurality? of layers can be laminated wood, solid wood, fiber cement, sheet metal, polymeric industrial panels, plasterboard, wood-cement, different coupled plates, panels in polymeric or natural fiber or glass. The interspace can? be filled with loose, compact or cast materials, whether natural or synthetic, such as for example mineral, vegetable or glass fibres, volcanic stones, polymers, conglomerates or combinations of these.
