Description

Casetons composed of polystyrene blocks and concrete blocks for the execution of unidirectional slabs and bidirectional.

Object of the invention

The purpose of this model is the execution on site of unidirectional and / or bidirectional slabs through the placement of a lightening block piece of expanded polystyrene anchored laterally and / or transversely by concrete blocks The concrete blocks set with their weight to lightening blocks made of polystyrene; and so they constitute and delimit the longitudinal and transverse nerves of the forged

The structure is applicable in the building.

Background of the invention

Previously the lightening blocks that were used were primarily concrete or ceramic. In the unidirectional forging regulations a new material called expanded polystyrene appears, with which lightening blocks are manufactured reducing the weight of the floor due to the low density it has with respect to the other materials. In recent years the polystyrene has been gaining strength and with the implementation of total formwork due to the safety of the work has been cemented in the execution of forged unidirectional both bidirectional situ and with lightening expanded polystyrene blocks.

Currently, they are trying to get new systems that lower not only the amounts but also the hand of work. Therefore, more resistant elements are used to achieve greater lights or that bear greater loads or decrease their weight own using lightening elements.

Description of the invention

Characterize the casetones object of the present invention its special configuration to be a system mixed achieving the following constructive advantages:

- Reduction of the slab's own weight when having expanded polystyrene pieces. This reduction is observed in a decrease in amounts of steel in plants, pillars and Above all the foundation.

- Easy assembly with respect to the slab with lightening concrete blocks because there are pieces of less weight, which improves the man / m2 performance.

- The proposed system mix in the lattice concrete pieces that serve as lateral and / or transverse anchorage to the expanded polystyrene piece, which avoids the possibility of displacement of the polystyrene piece due to its low weight.

- Currently, in bidirectional slabs with lightening block of expanded polystyrene it is not possible to lower check of a correct concreting since it looks covered by a sheet of polystyrene. With our system you remove that porexpan plate so you could verify the correct concrete slab.

- With the removal of the sheet polystyrene the useful edge of the slab increases between a 5-15% achieving reductions in the amounts of steel.

- There is a smaller proportion of blocks of expanded polystyrene, no movement or swelling of the ferralla, by the passage of the operators, in the pieces of polystyrene decreasing the coatings and even, in some cases the absence of these.

- There is a versatility to perform a square or rectangular reticle just by changing the piece of polystyrene. In this way you can optimize the number of nerves depending on the load and the light that the slab carries.

The mixed lightening system consists of the mixture of concrete pieces (1), which will serve as an anchor for the polystyrene pieces (2). This anchor is guaranteed by the friction that occurs between both pieces, although you can make the piece of polystyrene with some convexity so that increase the adhesion between both pieces (Figure 7).

The plan form of the piece may be square (Figure 3) or rectangular (Figure 4) only increase the length of expanded polystyrene piece according to constructive needs, and their employment will be indicated both in bidirectional slabs (Figure 3 and 4) as unidirectional (Figure 6).

Description of the drawings and embodiment

Figs. 1 and 2 show lightening blocks for bidirectional forging, with the shape of a square block and rectangular respectively; being 1 piece of concrete and 2 piece from Porexpan. Figs. 3 and 4 represent a lightened area of a bidirectional forging; with square and rectangular block respectively. Fig. 5 shows the shape of the blocks lightening for unidirectional slab being 1 piece of concrete and 2 piece of porexpan. Fig. 6 represents a lightened area of a Forged one way. Fig. 7 shows geometric shapes of the lightening piece and as seen in the two bottom views, it it can give the piece some convexity to increase its effectiveness in the anchor.

Claims (1)

1. Lightening structure for bidirectional and / or unidirectional slabs designed to be executed on a flat formwork and in which lightening elements called cassettes or vaults constituted by a series of expanded polystyrene and concrete pieces participate, the latter being the ones that serve as lateral and / or transverse anchor to the first. The placement of these pieces determine longitudinal and / or transversal channels to each other, for the implementation of the corresponding reinforcement and construction of respective beams by filling with concrete. This system is characterized in that it is a mixed system with lightening pieces of expanded polystyrene and concrete. The first being between two pieces of the last material.
