Prefabricated self-supporting module for making building structures, more particularly swimming pools

Abstract

A prefabricated self-supporting module for making building structures, more particularly swimming pools, is provided. The module comprises a matrix made of foamed material and a supporting structure made of metal coupled to the matrix. The supporting structure made of metal may be embedded in the matrix made of foamed material (internal supporting structure) and/or cover the matrix made of foamed material (external supporting structure). Thanks to the provision of the supporting structure made of metal, the module is self-supporting, and it does not need any further reinforcements of reinforced concrete. Thanks to the provision of the supporting structure made of metal, the module can be used for making structural supporting elements such as floors, side walls, and so on. This module can be completely made and finished in the factory, so that the steps to be carried out on the construction site are extremely limited, with consequent economic saving.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

(9) With reference to FIG. 1, a prefabricated self-supporting module according to the invention, denoted as a whole by reference 1, is schematically shown. According to its more general features, the module 1 comprises a matrix made of foamed material 3 and a supporting structure made of metal 5 coupled to said matrix. Herein, foamed material means a material having a density lower than 0.1 kg/m.sup.3, more particularly a polymeric material having a density lower than 0.1 kg/dm.sup.3. Expanded polystyrene foam (EPS) and extruded polystyrene foam (XPS) may be advantageously used for making the matrix 3. The supporting structure 5 is preferably made of steel, more preferably made of stainless steel or steel with an anti-corrosion treatment (galvanizing, varnishing, and the like). However, other metals (e.g. aluminum) could also be used.

(10) Said supporting structure 5 can be an internal supporting structure, as in the example illustrated in FIG. 1: in this case the supporting structure made of metal 5 includes a plurality of beams 5a and/or uprights 5b embedded in the matrix made of foamed material 3. In this respect, it is evident that the supporting elements 5a, 5b of the supporting structure 5 do not necessarily have to be arranged horizontally or vertically, but they could also be differently oriented. Furthermore, they do not necessarily have to be straight.

(11) In addition or as an alternative to said beams and uprights, the supporting structure 5 could include elements made of metal which partially or completely cover the surface of the matrix made of foamed material 3 (external supporting structure).

(12) It is evident from FIG. 1 that the module 1 is intrinsically self-supporting and that the use of concrete is not necessary.

(13) It is also evident from FIG. 1 thatthanks to the provision of the supporting structure made of metal 5it is possible to use the module according to the invention for making structural elements such as floors, side walls and the like, as well as complex elements as in the example shown in FIG. 1, wherein the module 1 is a corner element of a building structure, comprising a first side wall portion 1a, a second side wall portion 1b orthogonal to said first portion, and a floor portion 1c orthogonal to both side wall portions 1a, 1b.

(14) It should be noted in this connection that, although in the example shown in FIG. 1 the walls 1a, 1b and 1c are flat and orthogonal to each other, such configuration is in no way to be understood in a limiting sense. The walls of the module 1 according to the invention could also be inclined with respect to one another by an angle other than 90. Furthermore, according to the invention it is also possible to make modules comprising one or more curved walls.

(15) Finally, it is evident that the modules 1 according to the invention can be completely made inside the production factory and that the only steps to be carried out on the construction site are laying said modules and connecting them to form the desired building structure.

(16) In this respect, FIG. 2 shows an example of a module 1 according to a second embodiment of the invention, in which said module 1 forms a side wall portion of a building structure and in FIG. 3 a building structure, namely a swimming pool 10, obtained by connecting together four modules 1 is schematically illustrated.

(17) Said modules 1 can be connected to each other and to the floor of the structure by means of any suitable technique known to the person skilled in the art, for example by gluing or by using dowels. Preferably, said connection mainly occurs at the supporting structure 5.

(18) It should be noted that, thanks to the provision of the supporting structure made of metal, the modules 1 can have a considerable size; for example, they can have a length of more than 4-5 meters, which allowsas in the case of FIG. 3to use only one module 1 for each side wall of the swimming pool 10.

(19) In this second embodiment, the modules 1 according to the invention are advantageously provided with a levelling system which allows to align each module with the adjacent modules and with the surrounding external structures.

(20) As more clearly seen in FIGS. 4 and 5, said system comprises a plurality of threaded bars 7, which are vertically arranged through the module 1, from the upper edge to the lower edge of said module. Each threaded bar passes through an upper metallic bored plate 9a, which is glued or otherwise fixed on the upper edge of the module 1, and through a lower metallic bored plate 9b, which is glued or otherwise fastened beneath the lower edge of the module 1. An internally threaded nut 11 is welded to one of said two plates (to the lower plate 9b in the example shown in the Figures).

(21) Since the nut 11 is integral with the plate and, therefore, with the module 1, turning the threaded bar 7 from its upper end in a clockwise or counterclockwise direction will result in a raising or, respectively, a lowering of the corresponding portion of the module 1 relative to the bar itself.

(22) In order to obtain the levelling of the module 1, it will therefore be sufficient to appropriately rotate each threaded bar 7 provided in the module 1.

(23) In the example shown in the Figures, the threaded bars 7 are inserted into the matrix made of foamed material 3. However, in an alternative embodiment of the invention, they could also be connected to uprights of the supporting structure made of metal.

(24) The aforesaid levelling arrangement can also be used when the module according to the invention is used for making floor elements (as in the case of the module 1 of FIG. 6) and when the module according to the invention is used for making secondary structures (as in the case of the module 1 shaped like a seat of FIG. 7).

(25) From the above disclosure, it will be evident to the person skilled in the art that the prefabricated self-supporting module according to the invention allows to achieve the objects set forth above, as it completely eliminates the need to use concrete and minimizes the steps to be carried out on the construction site.

(26) It will also be evident to the person skilled in the art that the detailed description given herein of a preferred embodiment of the invention has been provided merely by way of example and many variations and modifications are possible without departing from the scope of protection as defined by the appended claims.
