Abstract

Prestressed ceramic slab, which being especially suitable for biapoyados and also recessed openings, is characterized by being constituted from a plurality of prefabricated plates, structured on the basis of two rows of ceramic pieces, which define superiorly open openings and which affects mainly at the height of the plate, in which respective inner and longitudinal ribs are established, of prestressed concrete in the manufacturing workshop.

Description

Prestressed ceramic floor.

Object of the invention

The present invention relates to a slab, structured on the basis of a series of prefabricated plates in which ceramic pieces joined together by means of ribs of prestressed concrete, also in origin, that is to say in workshop, whose plates, of considerable dimensions, are intended to be inter-coupled on site, to form the total width of the floor, using concrete ribs made " in situ ".

The floor of the invention offers a magnificent Bending behavior positive, sharp and deformations.

Although specially designed for vain biapoyados, its use is also possible by embedments

Background of the invention

Within the scope of the practical application of the invention, that of construction, within the wide range of types of existing floor slabs, the ceramic floor slabs are structured based on ceramic vaults that are conveniently aligned, either on operating beams and previously established, or on a formwork of boards in which said alignments of vaults determine longitudinal grooves for obtaining " in situ " of said beams, the vaults being finally covered by a compression layer, in which the transverse reinforcement wires are established, especially when vault alignments are not interrupted to establish cross beams.

This building system of the floors presents a problem that focuses primarily on two aspects, on the one hand it is not feasible to obtain them without compression layer, and on the other the prestressing of the same forces, well to the use of prestressed beams, fully practiced in disuse, or to perform the prestressing of the floor slab itself work, which evidently makes the process.

Description of the invention

The floor that the invention proposes, despite its ceramic nature, allows prestressing in origin, that is in the prefabrication workshop, with the consequent cheaper costs that this implies.

For this purpose and more specifically, said floor is structured based on a plurality of sixty centimeters wide plates, each of which is constituted by two rows of equal ceramic pieces, being placed symmetrically with respect to each other, which define between yes a groove occupied by an inner and also longitudinal rib, of prestressed concrete, with its reinforcements conveniently prestressed in the manufacturing workshop, defining among them longitudinal grooves intended for the connection between such plates, by means of concrete contribution " in situ ".

According to another of the characteristics of the It is provided that the said plates also incorporate as essential feature a series of cross braces of reinforced concrete, established in transverse grooves of the ceramic pieces, also executed in the workshop, which obviously they have the purpose of giving resistance to bending transverse during lifting.

The floor is therefore made up of prefabricated slabs or plates, with prestressed longitudinal ribs of total height, also obtained with a prefabricated character, and joined together by partial height concrete ribs, obtained " in situ ", which are easily inter-coupled until achieve the final width required for said floor.

The slab thus structured needs a layer of compression.

The number, diameter and positioning of the prestressed steel wires or cords that participate in the said plates will be variable depending on the type of forged to obtain, and more specifically depending on the benefits planned for it.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a front elevation view of one of the prefabricated plates that participate in the slab prestressed ceramic object of the present invention.

Figure 2.- Shows a side elevation view of the same plate.

Figure 3.- Shows, finally, and according to a representation similar to that of figure 1, the side coupling between two slabs.

Preferred Embodiment of the Invention

In view of these figures and more specifically Figure 1, can be seen as each of the plates that participate in the prestressed ceramic slab that is recommended structured by two rows of ceramic pieces (1) -, which define each other a groove (2), which mostly affects in height to the plate and which is destined to materialize, by the contribution of concrete, in a longitudinal rib (3), in which The metal reinforcement (4) is conveniently embedded. gives the plate, and the floor as a whole, the character pretended to have repeatedly been mentioned with anteriority.

The two alignments of ceramic pieces (1) are equal and symmetrical with each other, defining on the side edges of the plates (5), also closed lower, as can be seen especially in Figure 3, but of lower height, so that in these grooves (5) the concrete (6) is poured " in situ " that is to constitute the connecting element between plates in the shaping of the floor.

Since these junction ribs (6) are carried out " in situ ", and as previously stated one of the objects of the invention is to avoid prestressing on site, such ribs (6) will lack armor and consequently prestress, which does not adversely affect the slab as such nerves (6) are not considered in the calculation.

Complementarily and as observed in the Figure 2, each slab plate is provided with grooves cross-sections (7), which are also filled in the workshop of prefabrication with individual concrete cords (8), also equipped with armor (9) of arming.

As also stated previously, the number, arrangement and diameter of the reinforcement rods (4) and (9) participating in the slab will be variable depending on the benefits required for it.

In this way a prestressed floor is achieved in the prefabrication workshop, based on wide plates easily interacoplables, which is especially suitable for spans biapoyados, also embedded, with a magnificent behavior to positive flexion, shear and deformations, entering partial collaboration of ceramic material, concrete and steels

It should only be noted finally that the structure described for the aforementioned prestressed ceramic plates shows directly the ceramic components that participate in it, so that by partial breaking of its base you access easily to its inner alveoli (10) for implantation of electrical or other conduits, prior to definitive coating of the underside of the floor, with plaster or with any other appropriate material.

It is not considered necessary to extend this description so that any subject matter expert understands the scope of the invention and the advantages thereof drift

The materials, shape, size and layout of the elements will be subject to variation as long as it do not suppose an alteration in the essentiality of the invention.

The terms in which this report has been written they should always be taken in a broad and non-limiting sense.
