Description

[0001] This invention is a divisional application of a patent application for an invention titled "Modular Hollow Load-Bearing Panel for Manufacturing Floor Slabs and the Like", with an application date of January 8, 2018, an international application number of PCT / ES2018 / 070009, and a national phase entry application number in China of 201880078278.7. Technical Field

[0002] As determined by the title, the object of the present invention is a modular hollow load-bearing panel for manufacturing floor slabs (slabs) and the like.

[0003] The present invention is defined by the structural and design characteristics of each of the elements that form part of the panel. These characteristics enable the panel to be used as a floor slab or the like, and since the panel has a grid of multi-directionally continuous holes on the inside of the panel, the panel is particularly light and does not negatively affect the load-bearing characteristics of the panel. In addition, the panel can effectively incorporate all the necessary features for such use, including housing installations and the like, and allows these necessary features to pass through.

[0004] Therefore, the present invention falls within the field of floor slab construction elements and the like used in the construction of buildings. Background Art

[0005] A floor slab is a structural element in the form of a horizontal plane (or an inclined plane in the case of a roof), which supports its own weight as well as overloads from use, partitioning, dynamic forces, etc., and does not require support over the entire surface of the floor slab. The said loads are transmitted to the ground through other elements of the structure such as beams, columns, walls, and foundations.

[0006] Currently, the most common floor slabs are made of reinforced concrete, usually consisting of concrete beams and joists (cast-in-place reinforced, precast, prestressed, etc.), blocks (or lightweight ceramic elements, concrete elements, etc.), and an upper layer of compacted concrete, and are slightly reinforced with steel mesh. Other types of floor slabs that are less common today, or are used for more specific purposes, are made using boards - the boards are laid on joists or beams arranged unidirectionally or bidirectionally made of wood or steel - or using structural panels - the structural panels include two wood boards adhered to both sides of a core of a lightweight material such as expanded polystyrene.

[0007] Among the different types of reinforced floor slabs, the following reinforced floor slabs are the most common:

[0008] - One-way floor slabs, which include a supporting beam (a supporting beam made of reinforced concrete or metal), blocks (installed between the supporting beams), or precast floor slabs, and a compressed reinforced concrete layer. The supporting beam transfers the load from the compressed layer to the perimeter beam or the edge beam.

[0009] - Two-way floor slabs or grid floor slabs: Two-way floor slabs or grid floor slabs are composed of coffers (or other lightweight elements) arranged as a grid. Between these coffers and on top of these shelves, a steel bar framework is installed in two directions and filled with concrete. The load is transferred to the columns by means of solid capitals. The coffers are usually removed (recycled).

[0010] - Other reinforced concrete floor slabs. Solid floor slabs are of a heavier type. Lighter floor slabs made of reinforced concrete with lighter fillers or one-way internal holes completely covered in concrete are usually called hollow floor slabs. Less thick reinforced floor slabs are also manufactured on one-way corrugated steel sheets, thus forming a structural component commonly called a composite floor slab. The described floor slabs are based on a one-way design and must be additionally supported by perimeter beams or edge beams.

[0011] Reinforced concrete floor slabs are the most commonly used type due to advantages such as the rigidity of the material, the availability of the material, and the low cost, despite disadvantages such as excessive weight and the inefficiency of the previously mentioned construction process. This type of floor slab can bear heavy loads, even for relatively wide spans, and this type of floor slab can form a monolithic component that is highly fire-resistant and has an acceptable sound insulation effect.

[0012] Therefore, in all of the aforementioned reinforced concrete floor slabs, whether one-way or two-way, although at the cost of their weight, the necessary structural endurance is achieved. Also in all of the aforementioned cases, the corresponding floor slabs do not have an accessible space in the form of a gap for placing or passing through installation parts or pipes. Therefore, the floor slabs used in building construction must be additionally supplemented by one or two hollow layers or chambers, which can be accessible or non-accessible, and are constructed to be attached to the upper or lower surface of the floor slab for placing the necessary installation parts or pipes, or for passing through installation parts or pipes. These construction layers additionally increase the actual thickness of the floor slab, but do not cooperate with the main structural function.

[0013] Therefore, the object of the present invention is to develop a slab that is significantly lighter in weight than currently common floor slabs, and whose load-bearing capacity and resistance are equal to or greater than those of currently common floor slabs, that combines all the indicated characteristics, and that can be manufactured in a quick, efficient, and systematic manner. The development of the slab is described as follows, and the basic characteristics of the slab are included in the first claim. SUMMARY OF THE INVENTION

[0014] An object of the present invention is a modular hollow endurance plate, which comprises two flat strips arranged in parallel, and the two flat strips are connected by an intermediate layered structure, and the layered structure forms repeated folding parts, bending parts or undulating parts in multiple directions.

[0015] The term "strip" refers to a structural element in the form of a two-dimensional rigid surface, which is not necessarily flat and has a relatively small thickness with respect to the remaining dimensions of the strip. Although the strip can be made by joining several different components, the structural element has a substantially continuous appearance, and / or the structural element can include some surface holes and / or linear stiffeners, and the linear stiffeners are included on the surface or longitudinally attached to the surface.

[0016] The folded, bent or undulating intermediate structure of the plate extends in the space included between the two flat outer strips and joins to the two flat outer strips at a plurality of points or regions that are intermittently joined and distributed, and the plurality of points or regions are defined by folding parts, bending parts or undulating parts in the form of slightly truncated tops or peaks, or coincide with some regions of the intermediate structure having larger folding parts or bending parts.

[0017] Due to the plurality of points or regions that are intermittently positioned and distributed, the flat outer strips can be relatively thin, and the flat outer strips are joined to the intermediate folding structure by means of the plurality of points or regions. In a specific case, the flat outer strips can include linear stiffeners, and the linear stiffeners are oriented according to the plane of the strip and connect the joining points or joining regions to the folded, bent or undulating intermediate structure, and / or the flat outer strips can also include surface holes or perforations distributed between the joining regions.

[0018] Due to the arrangement of the folded, bent or undulating intermediate structure that is intermittently fixed to the two flat outer strips arranged in parallel as described, at least two continuous gap-type chambers, channels or hollow spaces extending in at least two directions along the plate are obtained, and the chambers, channels or hollow spaces are at least included between each of the two flat outer strips and the intermediate structure.

[0019] For a specific use or application, the described design of the plate is advantageous due to additional functions, which result from the presence and geometry of the indicated chambers or hollow spaces, from the multi-directionally folded, curved or undulating form of the intermediate structure, and also from the special properties of the physical behavior (mechanical, thermal, acoustic, etc.) of the plate - said special properties being obtained due to the shape of the plate and being different from the properties of other existing structures.

[0020] One possible way to systematically generate forms of folded, curved or undulating intermediate structures like the described intermediate structure involves joining repeating modules, which enables the manufacture of the intermediate structure using a small number of types of components. In one possible implementation, the modules are in the form of truncated, hollow and trimmed pyramidal pieces with a specific number of sides or repeating combinations thereof.

[0021] Similarly, another possible way to systematically generate forms of folded, curved or undulating intermediate structures like the described intermediate structure is obtained by means of a surface that results from the movement of a flat, continuous and interrupted, curved or undulating generatrix along a likewise flat, continuous and interrupted, curved or undulating directrix, which even enables the manufacture of the intermediate structure by a continuous process.

[0022] Without excluding other possible uses or applications, the plate of the present invention offers several advantages for the integral manufacture of floor slabs and for the construction of enclosures including other structural systems and analogues. The modularity and light weight of the plate allow the plate to be substantially prefabricated in the form of wide plate panels or sections, which are transported to the site and assembled on site rather than being built in place. As previously mentioned, the structural arrangement of the multi-directionally separated plates enables the plates to be self-supporting. This means that when the plates are arranged horizontally, the plates can be supported over spans of typical building dimensions without the need to construct beams directly supported by columns. Similarly, the lighter weight of the plates facilitated by the structural arrangement of the plates enables the weight of the remaining structural elements that support the plates to be reduced. The presence of wide internal chambers or hollow spaces promotes significant sound and heat insulation capabilities for the specified use. The multi-directional continuity of the internal hollow spaces, as well as the adjacency of the internal hollow spaces to the flat outer strips, enables the hollow spaces to be used as permanently integrated channels, accessible for the placement of fittings and pipes, and even for the distribution of heat and cold to adjacent living spaces, thus eliminating the need to construct additional chambers, hollow spaces or channels.

[0023] Unless otherwise indicated, all technical and scientific terms used in this specification have the meanings commonly understood by one of ordinary skill in the art to which this invention pertains. When practicing the present invention, methods and materials similar or equivalent to those described in this specification may be used.

[0024] Throughout the specification and claims, the word "comprising" and its variations do not exclude other technical features, additives, components, or steps. For those skilled in the art, other objects, advantages, and features of the present invention can be inferred from both the description of the present invention and its practical applications.

[0029] For some possible embodiments of the modular hollow plate, Figure 3A 、 Figure 3B and Figure 3C show the disassembly of different types of modules or module components of the intermediate structure.

[0030] For possible alternatives to the embodiments of different components, the combination mechanism and joining mechanism of the modules in the foregoing figures are provided in Figure 4 .

[0031] Figure 5A 、 Figure 5B 、 Figure 5C and Figure 5DA perspective view of a preferred embodiment of the board object of the present invention based on the aforementioned figures is shown. The board object serves as an integral system for the floor slab of a building. In the figure, some parts of the board are successively pressed, so that the internal details of the components can be seen in this preferred embodiment of the board, and in particular, the internal details of the flat upper strip board and the lower strip board, as well as the connection mechanism between the individual modules that make up the intermediate structure can be seen. Detailed implementation

[0032] Referring to the accompanying drawings, different aspects of the modular hollow board object of the present invention will be described in detail below, and a preferred embodiment of the modular hollow board object will be described.

[0033] Figure 1A and Figure 1B A lightweight board object of the present invention is shown. In the most simplified embodiment of the present invention, the lightweight board object includes:

[0034] - A flat upper strip board 1,

[0035] - A flat lower strip board 2,

[0036] - A multi-directionally folded, curved or undulating intermediate structure 3 arranged between the upper strip board 1 and the lower strip board 2, and the intermediate structure 3 is joined to the upper strip board 1 and the lower strip board 2 at contact areas or connection points 4, 5 that are intermittently positioned and distributed, so that the intermediate structure 3 defines at least two gap-type and continuous chambers, channels or hollow spaces 6, 7 that extend in at least two different directions across the entire board.

[0037] Figure 1B Shows Figure 1A A simplified diagram of a perspective view of the same embodiment of the board shown in, in which the flat upper strip board 1 has been moved so that the intermediate structure 3 is visible.

[0038] In other possible embodiments of the board, the flat upper strip board 1 and the flat lower strip board 2 may respectively include perforations 10, 11 similar to those shown in Figure 1C The specific arrangement and geometric structure of the perforations do not necessarily coincide with those shown in Figure 1C shown, but the perforations cannot coincide with the joint areas or connection points 4, 5 of the flat strip board and the intermediate structure. Also in a supplementary manner, the flat upper strip board 1 and the flat lower strip board 2 may have linear strengthening elements oriented according to their respective planes.

[0039] In the case where the upper strip board 1 and the lower strip board 2 respectively include perforations 10, 11 similar to those of the Figure 1C perforations, the perforations respectively facilitate entry into the continuous gap-type chambers, channels or hollow spaces 6, 7 from the outside of the board.

[0040] Figure 1B , Figure 1D , Figure 1E and Figure 1F show general schematic views of other possible embodiments of the plate, wherein the intermediate structure may be in the form of a multi-directionally foldable, curved or undulating strip.

[0041] - In Figure 1B and Figure 1D , the intermediate structure 3 or 3.1 is in the form of a folded strip, wherein the corresponding multi-directional folds are formed by joining flat surfaces in different orientations, thereby defining a slightly truncated top or peak, and the top or peak constitutes the connection point or connection area 4, 5 between the folded strip and the flat upper strip 1 and the flat lower strip 2.

[0042] - In Figure 1E , the intermediate structure 3.2 is in the form of a multi-directionally undulating strip arranged in a curved and continuous form, thereby defining peaks and valleys, and the peaks and valleys constitute the connection point or connection area 4, 5 between the undulating strip and the upper strip 1 and the lower strip 2.

[0043] - In Figure 1F , the intermediate structure 3.3 has the shape of a curved strip formed by corresponding multi-directional protrusions, and the points with a greater degree of protrusion or depression of the curved strip constitute the connection point or connection area 4, 5 between the curved strip and the upper strip 1 and the lower strip 2.

[0044] For possible embodiments of the plate, such as those shown in Figure 1B , Figure 1D , Figure 1E and Figure 1F , the intermediate structure can be produced by joining repeating modules and by using known materials, mechanisms and processes for manufacturing and connection.

[0045] Relative to the foregoing embodiments, for some possible embodiments of the plate, such as those shown in Figure 1B , Figure 1E and Figure 1F , it must also be considered that in these cases, the shape of the folded, curved or undulating strip constituting the intermediate structure can be obtained by the following surface: the surface is slightly truncated if necessary, and is generated by the movement of a continuous and interrupted, curved or undulating flat generating surface through a flat, continuous and interrupted, curved or undulating directrix.

[0046] The joints between the upper contact region 4 of the intermediate structure and the flat upper strip 1, and between the lower contact region 5 of the intermediate structure and the flat lower strip 2 can be formed by means of known mechanisms which, in some possible embodiments, can include sheet metal or connectors, profiles, screws, male-female couplings, joints by means of adhesives, etc.

[0047] If the plates are used as an integral system for the floors of a building, the wide continuous interstitial spaces 6, 7 defined internally in the plates serve as integral hollow chambers, which are permanently accessible for the placement of installations and conduits and are even used for distributing heat and cold to adjacent living spaces, thus eliminating the need to construct additional chambers, spaces or conduits as is currently the case for floors used in the prior art.

[0048] In a possible embodiment of the plate used as an integral system for the floors of a building - in which the continuous channels 6, 7 are effectively used - the flat outer strips 1, 2 are arranged at a distance from each other such that the total thickness of the plate is not greater than the actual thickness of a typical plate in the prior art (where this actual thickness includes not only the edges of the load-bearing floor but also the thickness occupied by installations or pipes that have to be arranged attached to said load-bearing floor). In this case, it has been demonstrated by models and simulations that a lightweight plate with the said characteristics can be supported, in the span of typical building dimensions, in a manner of being directly rested on columns without the need to be supported by beams in any direction, due to the cooperation of the total thickness of the lightweight plate with the main structural function, thus supporting the weight of the overloads specified by the corresponding regulations, as Figure 2 shown.

[0049] Figure 2 Schematically shown is a typical construction process of an integral system for the floor 13 of a building based on the plate object of the present invention. First, the modules, the panels or the wide sections of the plate 12 are prefabricated. These modules or panels are transferred to the construction site and are supported directly by columns or posts, or by other previously placed modules or panels, and these modules or panels are dry-connected by means of mechanical joints and the application of adhesives or joint sealants. Finally, the necessary installations and pipes are placed inside the plate, and the flat upper strip is completed by installing the corresponding paving layer.

[0050] In some possible embodiments of the plate which can be made from a very small number of types of simple components, a multi-directionally folded, curved or undulating intermediate structure 3 is obtained by joining repeated modules. In a simpler possible embodiment, for the uses described above, the modules have the shape of hollow and trimmed truncated pyramidal pieces or pyramidal bodies, or repeated combinations of these shapes, such as Figure 3A , Figure 3Band Figure 3C As shown in Figure 3A In the embodiment, the truncated pyramid-shaped member 14 has a triangular base. Figure 3B In the embodiment, the truncated pyramid-shaped member 14 has a quadrilateral base. Figure 3C In the embodiment of FIG. 1 , the truncated pyramid-shaped element 14 has a hexagonal base. In all cases, the pyramidal shape can be obtained by means of different flat elements corresponding to the faces 15 of the body of the pyramid-shaped element, as in FIG. Figure 4 Schematically and generally shown in FIG.

[0051] In the complete assembly of the board, the face 15 of the truncated pyramid 14 passes from the flat lower strip 2 to the flat upper strip 1, said face remaining flat and connected to the flat outer strip, and in the case of manufacturing using flat components by any known method, not necessarily with Figure 4 The components can be connected to each other in a manner consistent with that shown in FIG, or even by means of metal plates or connectors, angle profiles, screws, tongue and groove connections, joints made by means of adhesives, etc.

[0052] For a possible embodiment of the intermediate structure 3 comprising a panel of joined modules in the shape of truncated pyramids 14, use can be made of members 16 having a geometry corresponding to the ends of the body of the pyramid, in order to facilitate the anchoring of the modules to the flat outer strips 1 and 2 in the respective connection areas or connection points 4 and 5. If the modules in the shape of truncated pyramids 14 are produced by joining flat members corresponding to the faces 15 of the truncated pyramids 14, according to Figure 4 As shown in FIG. 1 , the members 16 arranged on the ends of the main body of the pyramid-shaped element also serve to facilitate the connection of the flat members.

[0053] For a possible embodiment of a panel based on modules in the shape of truncated pyramids 14, the intermediate structure 3 is formed by joining said various modules, in Figure 4 In one of the two alternative possibilities shown, as shown at 17, the modules are arranged in a matrix that is repeated in accordance with their specific geometry, and the connection can be facilitated by means of the described members 16. Another possibility shown in the figures consists in the individual modules being arranged in a matrix that is repeated in accordance with their specific geometry, overlapping and close to each other, so that only these modules need to be connected to the flat outer strips 1 and 2, and the modules themselves serve as tongue and groove mechanisms for coupling the modules to each other.

[0054] Figure 5A , Figure 5B , Figure 5C and Figure 5D Shown based on Figure 3B and Figure 4Perspective view of a preferred embodiment of the plate object of the invention of a module in the shape of a truncated pyramid-shaped member, which plate object serves as an integral system for a floor slab 13 of a building.

[0055] It can be seen how the linear elements, members or reinforcing battens 8 can be attached to the flat upper strip 1. In this case, the linear elements, members or reinforcing battens 8 are oriented in two transverse directions and are regularly spaced apart from each other. The linear elements, members or reinforcing battens 8 can also be used as means for fastening by fitting or tongue-and-groove coupling of the modules of the intermediate structure 3, where the modules are truncated pyramid-shaped members 14 in the case shown.

[0056] The same consideration can be made for the lower strip 2. In other words, the linear reinforcing elements, members or battens 9 can also be used to couple the lower end portion of the body of the pyramid-shaped member to the lower strip.

[0057] Another possible similar embodiment form for fastening the individual modules includes: on the lower surface of the flat upper strip 1 and the upper surface of the flat lower strip 2, similar to Figure 5D as shown in, a series of protrusions, textures or perforations are made in the corresponding connection areas or connection points 4, 5 with geometries consistent with the geometries of the ends of the body of the pyramid-shaped member, such that the fastening of the elements of the intermediate structure to the flat outer strips is achieved by fitting.

[0058] Figure 5A , Figure 5B , Figure 5C and Figure 5D The preferred embodiments of the plates in will consist of a very small number of simple types of members with simple joining mechanisms, which can be made of common materials, such as fiber-reinforced or laminated gypsum board, wood fiber board, any other type of lightweight board, wooden profiles, metal profiles, etc.

[0059] Thus, the nature of the present invention and how to put the present invention into practice have been fully described. It must be noted that within the essential nature of the present invention, as long as the basic principles of the present invention are not changed, altered or modified, the present invention can be implemented according to other embodiments that are different in details from the embodiments shown by way of example and that will be equally covered by the sought protection.
