    [0004] Technical sector
    [0005]
    [0006] The present invention is related to the construction of plant platforms and vertical walls (walls) in building works, in general they are ribbed plate structures, for horizontal (forged) or vertical (walls) use, proposing a base Modular for said ribbed plates, developed with characteristics that facilitate the assembly of construction and improve the behavior in eventualities such as a building fire.
    [0007]
    [0008] State of the art
    [0009]
    [0010] Lightweight slab construction systems are known that improve the structural capacity and thermal and acoustic insulation of building plant platforms where such slabs are used, facilitating the assembly of the construction and reducing the labor necessary for its execution .
    [0011]
    [0012] These lightened slabs are formed with pieces of light material, such as polystyrene, polyurethane or other similar materials, which are joined together with longitudinal metal stringers, determining a surface provided with longitudinal channels configured by the pieces of light material. In said channels, reinforcements formed by metal bars are arranged, to extend on the surface formed a layer of concrete that is introduced into the longitudinal channels, thus determining a resistant floor with reinforcing ribs.
    [0013]
    [0014] These floors have, however, the disadvantage that, when a building fire occurs, the pieces of light material from the base of the floors are consumed, so that the metal stringers are not secured and fall, together with all the layers of coatings, which are precisely those that provide the first fire protection barrier, only the concrete layer of the floor remains, which is dangerous, since the concrete layer is directly exposed to the fire and can collapse (if reaches the critical temperature in steel armor, which are already only protected by the concrete coating) and sink the platform.
    [0015]
    [0016] On the other hand, in conventional systems the lightweight material pieces of the base of the slabs are assembled together by means of tongue and groove of the longitudinal ends thereof, which makes it necessary first to arrange these parts in the assembly of the slab base , and then place the reinforcements in the longitudinal channels, which determines the process of construction of the slabs.
    [0017]
    [0018] Object of the invention
    [0019]
    [0020] In accordance with the invention, a modular construction base is proposed for platforms (horizontal) and wall walls (vertical) in building works, in which structural characteristics are provided that improve the construction conditions and increase safety in case of building fire.
    [0021]
    [0022] The modular base object of the invention comprises modules formed by pieces of lightweight material, such as polyurethane, polystyrene or the like, which centrally have a longitudinal channel for receiving concrete in the upper part, said pieces being arranged consecutively in a longitudinal direction , joined by metal stringers, for example "C" profile, which are facing each other passing through the set of consecutive pieces of light material, incorporating metal plates between the consecutive pieces of light material, which are established as crossbars separators between the metal stringers, said plates presenting at the top a recess that partially corresponds to the height of the upper longitudinal channel determined by the consecutive pieces of light material, and leaving the lateral edges of said upper recess of the metal plates about prominent inward tabs q They partially penetrate the longitudinal channel, such that when a concrete layer is spread over the modular base, the metal plates are attached to the concrete by means of the flanges.
    [0023]
    [0024] In this way, the metal structure formed by the metal stringers of the modules of the construction base and the metal plates that make crossbars between said stringers is joined in a resistant way to the concrete layer, so, if consumed by light pieces of light material, the metal structure of the base is attached to the concrete layer, avoiding the direct exposure of said concrete layer to the fire as the metal structure is suspended from the primary structure of reinforced concrete and gives solid support to fire resistant coatings.
    [0025]
    [0026] In the tabs of the metal plates fit frames that have on the upper and lower sides some conformations as tweezers, in which longitudinal bars are formed that form a reinforcement in the channel of the consecutive pieces of light material.
    [0027]
    [0028] The metal plate tabs that are embedded in the concrete are shaped like a dovetail, which provides a solid anchor between the metal plates and the concrete structure.
    [0029]
    [0030] The frames of support of the bars of the reinforcements, have a recess in the front of one of the lateral sections and another recess in the back of the opposite lateral section, with which said racks can be mounted very easily by means of a lace of bayonet on the tabs of the metal plates that go between the consecutive pieces of light material, introducing said racks in a laterally inclined position in the longitudinal channels defined by the consecutive pieces of light material, then turning said racks to a perpendicular position transverse in which they fit on the tabs of the metal plates.
    [0031]
    [0032] On the other hand, the bars with which the reinforcements are formed in the channels defined by the consecutive pieces of lightweight material fit into the conformations as clamps of the mounting frames, with the possibility of rotation and longitudinal displacement, thus facilitating the positioning of said bars as necessary, in the construction of the base assembly, in each application.
    [0033]
    [0034] The metal plates that are arranged between the consecutive pieces of light material in the base are provided with an opening in its middle area, to pass through said opening cables and tubes of the building facilities, which facilitates the assembly of the installations; also allowing suspended ceilings or temporary elements used during construction works to hang from the metal plates. On the lower edge the metal plates also have a small signal notch, corresponding to the position of the opening of the plates, to facilitate the work of the installers, by providing them with a reference of the situation in which the opening of the metal plates, once the construction is done.
    [0035]
    [0036] Likewise, the metal stringers with which the base modules are formed have, along the soul of the profile of said stringers, openings for the passage of cables and pipes, with signal notches on the sides of the profile, corresponding to the positions of the openings, to facilitate the work of the installers.
    [0037]
    [0038] A module is thus obtained to form a construction base by means of the collateral union of consecutive modules, which are associated with each other by fitting between reciprocal tongue and groove conformations that the light material pieces possess on the sides.
    [0039]
    [0040] The modular base is thus easy to build, and the necessary modules can be mounted in the workshop, and then incorporated on site by simple placement of lateral tongue and groove fittings between them, thus forming the base to extend the concrete layer on it, which penetrates the Longitudinal channels defined by the consecutive pieces of light material, where the tabs of the upper recess of the metal plates arranged between the consecutive pieces of light material are embedded in the concrete.
    [0041]
    [0042] With all this, the construction base that is recommended results from very advantageous characteristics for the application to which it is intended, acquiring its own life and preferential character with respect to the conventional bases of the same application.

    [0056]
    [0057] Detailed description of the invention
    [0058]
    [0059] The object of the invention relates to a construction base, for horizontal platforms of building plants or vertical walls (walls), in general for all types of vertical or horizontal ribbed plates. The base is formed by association of modules that are joined by collateral tongue and groove fitting between them.
    [0060]
    [0061] Each module of the base comprises a succession of pieces (1) of light material, such as polyurethane or polystyrene, which are joined by two metal stringers (2) that pass through the pieces (1), to join extreme pieces (3) which are also of light material, presenting both the pieces (1) and the extreme pieces (3), centrally at the top, a depression (4) by means of which they determine a longitudinal channel in the module assembly that is it forms with the succession of said pieces (1) and (3), said longitudinal channel being configured to receive a concrete layer.
    [0062]
    [0063] The metal stringers (2) are of a "C" profile, arranged facing each other in the passage through the pieces (1), including a metal plate (5) between the fronts of the consecutive pieces (1), the which fits into the profiles of the metal stringers (2), making the separating crossbar between them.
    [0064]
    [0065] The aforementioned metal plates (5) that are included between consecutive pieces (1), have a recess (6) in the upper part that corresponds partially to the height of the depression (4) of the pieces (1), leaving the lateral edges of that recess (6) of the metal plates (5) prominent inward tabs (7) that partially penetrate the depression (4) of the pieces (1) where the concrete is applied.
    [0066] In the longitudinal channel defined by the depression (4) of the pieces (1), frames (8) are arranged which are fastened by bayonet fit on the said tabs (7) of the metal plates (5); for which, said frames (8) have a recess (9) at the front of one of their lateral sections and a similar recess (9) at the rear of the opposite side, so that each frame (8) can enter the longitudinal channel defined by the depression (4) of the pieces (1), in a laterally inclined position, as seen in figures 3 and 3A, and then rotate it to a transversely perpendicular position in which the recesses (9 ) fit on the tabs (7) of the corresponding metal plate (5).
    [0067]
    [0068] The frames (8) have in their upper section and in their lower section some conformations (10) by way of tweezers, which allow the mounting of bars (11), as seen in Figure 4, to form a armor along the longitudinal channel defined by the depression (4) of the pieces (1); the bars (11) being held in the conformations (10) as tweezers, with the possibility of being able to rotate and move longitudinally, thus facilitating their positioning as required.
    [0069]
    [0070] In this way it is very easy to form and assemble a reinforcement in the longitudinal channel of the module, since the frames (8) of support of the reinforcement are incorporated by simple insertion and a small turn, so that they are held in the channel longitudinally defined by the components (1) components of the module, while the bars (11) of the reinforcement are held by a simple fit in the conformations (10) by way of tweezers, then said bars can be rotated and displaced longitudinally ( 10), to adjust its positioning.
    [0071]
    [0072] The light component parts (1) components of the module, have on their sides some conformations (12) of reciprocal configuration to establish a tongue and groove joint, so that successive modules can be collaterally associated by means of corresponding tongue and groove joints between them, simply placing successively one module after another, which makes it possible to form a construction base like that of figure 5, of the desired dimension, to extend a concrete layer on it.
    [0073]
    [0074] The concrete layer that extends over the base penetrates the longitudinal channels defined by the depressions (4) of the pieces (1) of light material, where the layer of concrete determines ribs reinforced by the reinforcements formed by the bars (11), the tabs (7) of the metal plates (5) being embedded in the concrete, whereby the base is attached to the concrete layer in a resistant manner , so that if there is a fire in the building that consumes the pieces (1) of light material, the metal structure of the base remains attached to the concrete layer.
    [0075]
    [0076] This avoids the direct exposure of the construction to the fire, since gypsum boards or plastering supports are screwed onto the metal structure that have the ability to resist a certain time to the flames, avoiding direct exposure of the primary concrete structure . In addition, ultimately, the frames (8) for placing the reinforcements guarantee the coating of the reinforcements with the concrete and therefore a certain fire resistance according to the project.
    [0077]
    [0078] In a particular way, the flanges (7) of the metal plates (5) are shaped like a dovetail (13), which anchor the plates (5) solidly to the primary structure of reinforced concrete, which makes it more resistant clamping between the base and the concrete layer.
    [0079]
    [0080] The metal plates (5) have in their middle area an opening (14) for the passage of cables and pipes of the building facilities, facilitating the assembly of said facilities; and in correspondence with that opening (14) the lower edge of the metal plates (5) has a signal notch (15), which serves as a reference of the position of the opening (14), facilitating the work of the installers.
    [0081]
    [0082] The profiles of the metal stringers (2) that hold the pieces (1) of light material, have, in turn, distributed along its soul, openings (16), for the passage of cables and tubes of the building facilities, said openings (16) being referenced by corresponding signal notches (17) at the edges of the profiles, to also facilitate the work of the installers.
