Description

[0001] The present invention relates to a modular industrial construction system for the construction of slabs and lightweight roofs, which are formed by one or more prefabricated lightweight modules in order to be able to form structurally resistant and stable slabs, even using dry construction techniques.Background of the invention

[0002] Various modular construction systems are known, that is, those that are composed of at least some prefabricated modules of polymeric material incorporated into metal trays and, therefore, of a light weight with respect to the slabs of usual construction materials.

[0003] Among these known systems, there are modular construction systems with cores of polymeric material that are characterized in that they have mesh rods that at some point are associated with the modules of polymeric material, either in auxiliary parts that are fitted to said polymeric module, or by having a common base on which various polymeric modules rest, between which the rods are placed that will then form the reinforcement of the slab once the setting material has been poured. These previous systems require the installation of said mesh, as well as the organization of the polymeric modules in the common base.

[0004] In other modular construction systems, individual blocks of polymeric material wrapped in corrugated sheet metal are used, which are perimetrically adapted to the complete shape of the block and which are coupled with other individual blocks to form a slab assembly, thanks to the combination of the corrugated sheet metal that completely covers and is geometrically adapted to the outer perimeter of the block.

[0005] Construction systems are also known, wherein the structural function is provided by high-strength structural profiles such as IPN, HEB or similar profiles, to which lower enclosures are coupled, on which they are independent and which contain the polymeric blocks and which are joined together structurally by means of a metal mesh and a setting compound that joins the assembly.

[0006] Thus, it is necessary to provide a modular construction system that provides strength and structural stability with an on-site installation that can be carried out dry or with setting material and, in both cases, allows having a complete upper surface installation.Description of the invention

[0007] The purpose of the present invention is to provide a modular industrial construction system for the construction of slabs and lightweight roofs, in accordance with the claims provided, which solves the aforementioned drawbacks, presenting the advantages of a modular industrial construction system that allows the complete installation prior to surface finish coatings, both dry construction techniques and with setting material in its final layer prior to finishing. This has advantageous configurations both for installation on site and for carrying out additional installations in the building, presenting other advantages that will be described herein.

[0008] In accordance with the indicated objectives, and according to a first embodiment, the present invention provides a modular industrial construction system for the construction of slabs and lightweight roofs, including a piece / block of lightening polymeric material and a lower metal base thereof with metal side walls, which form modules that are joined at the side to form the assembly.

[0009] Advantageously, the modular industrial construction system, object of the invention, comprises, for each of the modules: a metal tray with a horizontal lower base and two vertical side ribs extending longitudinally along the entire length of the base of the metal tray, the module having a "U" cross section, wherein at least one of the two vertical side ribs comprises an upper free end with a flange-like geometry with at least one horizontal lip, the height of which from its horizontal base is the same as a maximum height of the upper surface of the piece / block of polymeric material; at least one piece / block of polymeric material, wherein this piece / block is configured with a width that fits in the lower base between the vertical side ribs and with a maximum height of its upper surface equal to the height of the horizontal lip of the end flange of the at least one vertical side rib, leaving free, in this upper surface of the piece / block, the height corresponding to a previous side section which corresponds to the location of the flange, the lower part of said accessible flange being free to be occupied by the piece / block; means of connection between modules by at least their side ribs.

[0010] The modular industrial construction system is formed by one or more modules joined together and with a final covering layer, at least, on the upper surface of the piece / block and on the horizontal lip of the end flange of at least one vertical side rib.

[0011] With this advantageous configuration, it is possible to have a modular industrial construction system that allows its installation on site: with a final upper surface with a covering layer of setting material, such as concrete or the like, allowing the metal structure to pass through the space created by the free height on the upper surface of the piece / block corresponding to the previous side section, which corresponds to the location of the flange, configured to leave the lower part of said flange accessible, so as to allow the entry of setting material under said flange and the possible installation of mesh prior to the pouring of the setting material, or the use of setting material with non-ferrous fibres, or with a finishing board or sheet that, without modifications in its flat configuration, supports, in a balanced way, the part of the upper surface of the piece / block of polymeric material and the horizontal lip of the flange of the vertical side ribs, since both have the same maximum upper level, allowing their installation in a simple and effective way and achieving a stable flat finishing surface, without the use of setting elements, or other dry levelling systems.

[0012] By way of clarification, when reference is made herein to sections, surfaces or any element or assembly in a horizontal position or orientation, it should be understood that it is used when taking as reference the position and orientation of a conventional and usual configuration of the assembly in said substantially horizontal arrangement of the assembly, wherein any other inclined or vertical arrangement must be taken into account to simply modify the reference terminology on the elements originally indicated as horizontal.

[0013] Preferably, with the aim of improving the properties of the optional configuration of having a final upper covering layer based on setting material, the flange comprises at least one lip of vertical configuration at its outermost section, at the back of the horizontal lip.

[0014] According to a possible embodiment of the invention, the horizontal section that forms the horizontal lip of the flange has a clearance from the vertical rib of at least 4 cm. This allows the anchoring / fixing of the elements forming the upper surface covering layer with dry elements, as well as allowing improvement of the properties of the fixing of the upper surface covering layer by setting material.

[0015] Also preferably, the metal tray with the horizontal lower base and the vertical side ribs containing the flange with horizontal lip, are made of the same continuous piece of metal material, usually achieved by a bending operation thereof. This configuration of a metal tray that includes in one and the same continuous piece, both the lower base and the side ribs and their corresponding flanges, allows having an element with mechanical properties superior to the products of the state of the art that form the metal tray in different parts.

[0016] According to a preferred embodiment of the invention, the modular industrial construction system is formed by one or more modules joined together laterally between vertical ribs, wherein at least the end modules positioned more on the outside of the formed assembly, comprise an outer vertical rib with a terminal horizontal lip at the maximum height of the piece / block that extends towards the outside of the module, and wherein the intermediate modules comprise both vertical side ribs with their upper free ends with flange-like geometry with the horizontal lip at the maximum height of the upper surface of the piece / block.

[0017] This preferred configuration allows a construction system to be made wherein its side ends have a horizontal lip facing away from the construction system, allowing better support and fixing to the structural support element thereof.

[0018] According to another preferred embodiment of the invention, the modular industrial construction system is formed by one or more modules joined together laterally between side ribs, wherein at least the end modules positioned further outside the formed assembly, comprise an outer vertical end side rib with a height lower than the maximum height of the piece / block and without a flange at its upper free end, and wherein the intermediate modules comprise both vertical side ribs with their upper free ends with flange-like geometry, with the lip horizontal at the maximum height level of the upper surface of the piece / block.

[0019] This configuration allows a set of several modules, conventionally three or more, to be made, although other configurations of one or more modules are possible, wherein the modules of the two ends have an outermost vertical side rib of smaller size, to avoid having the entire height of the rib up to the maximum dimension of the piece / block, or having configured sets of modules with interior and / or exterior modules of this type.

[0020] Alternatively to the above, the modular industrial construction system is formed by one or more modules joined together, wherein all the modules, internal and ends, comprise both vertical side ribs with their upper free ends with flange-like geometry, having at least the horizontal lip at a maximum height level from its horizontal base, equal to the height of the upper surface of the piece / block of polymeric material.

[0021] According to a possible embodiment of the invention, at least the inner modules, which are not terminal at the ends of the construction system, have both horizontal lips facing the same side, configured so that each inner module fits the horizontal lip of one above the flange of the adjacent module, on one side, while on the other side it receives above its other flange the horizontal lip of the other adjacent module on the other side.

[0022] This configuration allows making a support between modules in a vertical direction, by placing the horizontal lips of the flanges of the side vertical ribs, one on top of the other contiguous module, which improves the stability of the assembly and allows a fixation between modules, in addition to that made in the vertical sections of the ribs, in the horizontal plane of superposition of the two horizontal lips, one of each module.

[0023] According to an optional, although preferred embodiment of the invention, the vertical side ribs comprise die-cuts, at least at their longitudinal ends, configured to receive the insertion of reinforced beams and transverse brackets. This allows simple and adequate integration of the set of modules to the adjoining structure.

[0024] According to an optional embodiment on the configuration of the piece / block, it is necessary that at least one piece / block, of at least one of the modules that make up the modular industrial construction system, comprises a grooving, passage or housing on at least one of its perimeter surfaces, this grooving, passages or housings being configured to house both pre-installations of services and supplies, tubes, wiring or the like, as well as, possibly, equipment.

[0025] This additional characteristic of the pieces / blocks allows pre-installations to be carried out prior to the installation of the construction system in the final location, or even to be carried out on site, once installed, without having to make modifications to the metal trays and the pieces / coffers, to carry out the unseen passage of said installations or the installation of equipment.

[0026] According to a specific embodiment of the above concept, the upper surface of the piece / block of polymeric material comprises a multiple grooving configured to receive an underfloor heating installation, such that it is at the upper end of the construction system and in contact with the final covering layer. This specific configuration allows the upper part of the piece / block to be pre-configured to be able to receive this installation of water tubes for underfloor heating, without having to carry out complementary actions on the installation surface, which accelerates the time and reduces costs of this installation, which is to be carried out prior to the placement of the upper final covering layer.

[0027] Also specifically on these latter embodiments, the bottom surface of the piece / block of polymeric material, comprises at least one grooving configured to receive an installation of tubes, wiring or the like, between the piece / block of polymeric material and the base of the metal tray. This specific configuration allows the passage of installations by pre-established steps at the base of the piece / coffer of polymeric material, which minimises the time and costs of cutting or installing pipes that pass through the module.

[0028] Preferably, all these passages, grooves or housings of a module, have service hatches in the closing surfaces of this module, configured for maintenance and / or installation access to these grooves, passages or housings, including when they have been installed on site. Usually, these service hatches are made at the bottom of the module, creating hatches or similar for access to these pre-established cavities in the pieces / blocks or between these pieces / blocks and the metal tray.

[0029] According to one possible embodiment of the invention, the upper final covering layer is a board, plate or similar that is fixed directly on the horizontal lip of the end flange of at least one vertical side rib of the metal tray of each module, the surface of said board, plate or similar being between fixing points on the horizontal lip in contact with the upper surface of the piece / block. Thanks to having the same maximum height of the horizontal lip of the flange of the vertical side rib, as the maximum height of the upper surface of the piece / block, this achieves the installation of a simple board or similar acting as a final covering surface without further actions, achieving an effective and stable rest on both surfaces of the two elements, reducing in turn the costs and times of this final covering by dry material.

[0030] According to an alternative embodiment with respect to the one above, the upper final covering layer is a layer of setting material that covers the upper surface of the piece / block, also remaining in the interior spaces between said upper surface of the piece / block and the end flange of the at least one vertical side rib. The main configuration of the module that forms the construction system of the invention allows this alternative configuration of the final covering layer, allowing finishing by means of setting material that, when introduced into the gaps between the piece / coffer and the lower area of the flange of the vertical rib, achieves an efficient joining of this covering layer with the module.

[0031] Preferably for this latter embodiment, the upper final covering layer of setting material comprises metal reinforcement, also referred to herein as mesh, or non-ferrous fibres in place of the mesh.

[0032] According to a preferred embodiment of the invention, complementary to the previous embodiments, the modular industrial construction system comprises a lower back plate configured as a support element to support and join the set of modules. Optionally with respect to this embodiment, the lower back plate has a composition or finish that is fire-retardant or fire-resistant.

[0033] With this back plate it is possible to improve the joining and support conditions of the modules thanks to the properties of the plate itself, among which can be found compositions and / or coatings of these plates that have fire-retardant, fire-resistant, water-repellent or other properties associated with the plate or board itself

[0034] In this way, this is a modular industrial construction system for the construction of slabs and lightweight roofs that by itself allows safe and resistant slabs to be made with its dry installation and with a surface finishing solution that can be both dry and by means of setting material, including means that optimize and reduce the times and costs of passing installations through them or installing equipment in an accessible way.Brief description of the drawings

[0036] The construction system (10) of the modular industrial type of construction of slabs and lightweight roofs, as can be seen in figures 1 to 7, is formed in a common way to all the embodiments by one or more modules (20) formed by a metal tray (21) wherein its cross section is "U" shaped with a horizontal lower base (22) and vertical sides in the form of ribs (23, 23') that extend longitudinally along the tray. This metal tray (21), with its base (22) and its side ribs in the different configurations indicated below, are made of a single piece of steel-type material, with a thickness that will preferably be between 2 and 3 mm with a preferred maximum height of its vertical side ribs between 150 to 330 mm, although they can reach 400 or more. These measurements are preferred, but others dimensioned to obtain particular structural properties can be carried out without altering the essence of configuration of the invention adapting to the needs of particular projects.

[0037] This configuration of the metal tray (21) forms a space with its upper part open where one or more pieces / blocks (30) of polymeric material fit, to thus complete said space of the metal tray (21) at least in its width and in the majority of its length, being able to leave small terminal areas free, longitudinally speaking, for its better attachment to the adjacent structure of the installation point. The width of each piece / block will be that of the base (22) reduced between approximately 7 and 13 mm for its assembly.

[0038] According to a preferred embodiment of the invention, as can be seen in figures 1 and 2, the metal tray comprises at least one side rib (23') with a flange (24) at its upper end that comprises a horizontal lip (24.1) with a height with respect to the lower base (22), equal to the maximum height of the upper surface (31) of the piece / block (30). This piece / block (30) is coupled laterally to the width of said "U"-shaped metal tray, the width being understood as the transverse dimension of the module (20), as shown in the sections of figures 2 to 7.

[0039] The metal tray (21) has several alternative embodiments that can coexist in the same set of modules that form the construction system (10). According to a first embodiment, as can be seen in figures 1 and 2, the modules (20"), preferably the ends, are formed in a metal tray (21) with a single side rib (23') with upper flange (24) and another rib (23) with a lower height without upper flange (24).

[0040] As another embodiment of the metal trays (21), the inner modules (20) have another tray configuration (21), wherein their two side ribs (23') have said upper flange (24) flush with the maximum level of the upper surface (31) of the piece / block (30).

[0041] Also as an alternative to the other two embodiments of the metal trays (21) above, we have in the end modules (20'), located on the sides of the construction system (10), the tray (21) comprising a vertical rib (23 ") in its outermost position that comprises a flange (24) with a terminal horizontal lip (24.3), at the maximum height of the piece / block (30), which extends towards the outside of the module configured. Said terminal horizontal lip (24.3) rests on the structure of the construction and can be fixed more easily and safely to it.

[0042] In these embodiments of the metal tray (21), this metal tray (21) is formed by a single continuous metal piece that completely forms its "U" section forming by bending or a similar process the horizontal lower base (22), the side ribs (23, 23', 23") and, where appropriate, the flange with the corresponding lip(s) (24.1, 24.2, 24.3).

[0043] In figures 1 and 3 another preferred embodiment can be seen, based on the combination of the different metal trays (21) of the invention, wherein the modules (20) comprise on both vertical side ribs (23') the upper flanges (24) facing towards the inside of the piece / coffer (30) itself, increasing the support surface for a covering surface (40) formed by a board that is fixed to them, creating a dry construction system, without the need for setting material.

[0044] Alternatively, as can be seen in figures 4 and 6, the inner modules (20") are formed by metal trays (21) with a single rib (23') with a flange, while the other rib (23) has a lower height and does not have a flange (24). There may be embodiments that alternate the two embodiments of metal trays (21) within the same construction system (10), having specific embodiments that have the modules at the side ends of the construction system (10) with the side ribs (23) located at the end without a flange (24), but the rest of the modules are configured with two ribs (23') with a flange (24).

[0045] As can be seen in figure 7, the construction system (10) comprises a module (20') at each of its two ends wherein the metal tray (21) comprises an outer vertical rib (23") with a flange (24") that comprises a terminal horizontal lip (24.3) at the maximum height of the piece / block (30) that extends towards the outside of the module (20'). Intermediate modules (20) are joined to each of these two end modules (20') both comprising vertical side ribs (23') with their upper free ends with flange-like geometry (24) with the horizontal lip (24.1) at the maximum height of the upper surface (31) of the piece / block (30). In this embodiment, both horizontal lips (24.1) extend in the same direction within the plane along which they extend, one facing towards the interior of the module (20) itself and the other facing towards the adjacent module, wherein when joining between modules a coupling or support is made between a vertical rib (23) with a flange facing away from the module resting on a flange of the vertical rib (23) of the adjacent module facing towards the interior of its own module. This configuration allows better support between modules as well as the possibility of applying the attachment means, in addition to the vertical side sections, on the overlapping sections of the horizontal lips of the flange.

[0046] The flanges (24) of the side ribs (23') comprise, in addition to the horizontal lip (24.1), a terminal vertical configuration lip (24.2), which allows better reception and joining of the covering layer (40) and its metal structure as a mesh or reinforcement, as shown in figures 4 and 6. In addition, as can be seen in figure 7, in the case of overlapping horizontal lips of adjacent modules, when there is this terminal vertical lip (24.2), an anchorage between both geometries is achieved both in a horizontal plane and in a vertical plane.

[0047] The pieces / blocks (30) of polymeric material are of expanded polystyrene (EPS) in these embodiments, of 15.0 kg / m3 nominal density, although other materials and densities can be used. The geometry of these pieces / blocks (30) allows them to fit into the space formed by the metal tray (21) in its transverse direction, and multiple pieces / blocks (30) can be placed longitudinally fully or partially contiguous to the complete length of the module. In height, taken from the base (22) of the metal tray (21) the upper surface (31) of the coffered piece at its maximum level is that of the horizontal lip (24.1) of the flange (24) of the rib (23') of the tray, leaving free of polymeric material a side section (26) before the flange (23) to preferably house the metal structure to be incorporated at the structural and / or reinforcement level (41) of joining of the covering layer (40) by setting material, of concrete.

[0048] The joining of the modules (20) is carried out in these embodiments by mechanical joints between the adjoining vertical ribs (23,23') of two modules (20), either in the perforations that the ribs (23, 23') may comprise or in specific holes made a posteriori for this purpose of joining. In this case, steel nails, although they can be conventional alternative mechanical systems that provide the joint with sufficient tensile and shear strength. For applications wherein setting material is used to have a final covering layer, the joining of the modules (10) is also carried out in an additional or alternative way, by adding said setting material and passing it through the longitudinal holes in the ribs (23') at a dimension wherein they are accessible by having the height of the piece / block (30) less than the height of the flange (24), as indicated above.

[0049] The vertical side ribs (23, 23') of the metal tray (21) comprise die-cuttings at their longitudinal ends, configured to receive the insertion of reinforced beams and transverse brackets, these having, in these described embodiments, holes for the passage of metal structures if necessary and holes for the passage of setting material, as indicated.

[0050] The pieces / blocks (30), as can be seen in figures 5 and 6, can comprise grooves, passages or housings (32) to incorporate pipes, tubes, wiring or even equipment in parts of pieces / blocks (30) with said spaces or partially replacing the number of pieces / blocks (30) of a module. In these figures, grooves can be seen in the upper surface (31) for the installation, for example, of the ducts corresponding to the installation of underfloor heating, as well as spaces, channels or the like in the lower surface (33) that are accessible from the bottom by hatches or the like.

[0051] Common to these previous embodiments, the modular industrial construction system (10) comprises a lower back plate (16) configured as an aid to the support and joining of the set of modules (20), which helps the grouping of the modules being able to provide this lower part with: finishing surfaces, accesses-service hatches to the passages, housings and spaces created in the pieces / blocks (30), coinciding with the accesses-service hatches of the metal tray (21), properties with respect to the environment wherein the construction system is installed, such as fire-retardant or fire-resistant properties, water-repellent properties or others that are applied in a conventional manner to surface coatings in buildings or structures.

[0052] As indicated in the previous embodiments, the construction system can incorporate a final covering layer (40) where it can preferably be made with: setting material, including a metal or mesh structure and a final finishing surface; or dry material such as OBS board, preferably class / quality III.

[0053] By way of example, as can be seen in figure 8, a construction system (10) can be predimensioned with respect to the desired limit load, by adjusting thicknesses of the metal tray, the width of the metal tray itself and the thickness of the compression layer, i.e. the concrete that forms the covering surface in this example.

[0054] Although reference has been made to a specific embodiment of the invention, it is evident to a person skilled in the art that the industrial construction system of slabs and lightweight roofs described herein is susceptible to numerous variations and modifications, and that all the aforementioned details can be replaced by other technically equivalent details, without departing from the scope of protection defined by the attached claims.
