FR2462525A1 - Wall block of square U-shape in plan - uses quarter length leg width and is placed in staggered rows with legs interlocking to form voided wall - Google Patents

Abstract

The range of prefabricated wall blocks uses a module (1) of a square angled 'U' shape in plan, the leg (7,8) thickness being equal to a quarter of the overall length (2). A cavity wall is built by using two staggered longitudinal rows with the legs projecting into the cavity. The internal leg faces include vertical tongue and groove formations (12,13), and the geometry is such that the legs of an internal block house and connect to the adjacent legs of two external blocks and vice versa. The cavity may be filled with site concrete and 'T' section insert tiles (4) may define partial permanent voids (5). Corner blocks may include a square full thickness permanent form (6) for cast in situ concrete columns.

Description

Technical area.

The present invention relates to improvements to devices for constituting building walls using prefabricated elements comprising two wings symmetrical with respect to the vertical median plane, said wings being perpendicular to the facing and their sides facing each other being a quarter of the width of each element and have teeth cooperating with identical elements, the facing of which is turned on the other side of the wall, the thickness of the wings being such that there are free spaces within the wall. between the wings of the elements.

Problem.

I1 'is to be able to quickly realize walls or walls by stacking elements that can be easily handled without external equipment and attached to one another without mortar except concrete for the posts. It is also a question of making these walls with suitable thermal insulation.

State of the prior art and drawbacks.

 The state of the art in this area is constituted by French patent 1,461,207 filed on December 10, 1965 in the names of the inventors. This device allowed rapid construction of walls or walls, but these had a constant thickness with the same element and the insulation could not be easily achieved. In addition, difficulties were encountered in making the ends of the walls and the angles as well as the rebates of the bays.

 The present invention is intended to remedy these various drawbacks by certain improvements and certain additions.

Statement of the invention.

The invention is mainly characterized by the fact that the assembly of profiles in
T filling most of said free spaces, said sections engaging vertically over at least part of the total height of the wall 3 the rest of the free space being filled with hydraulic binder, possibly reinforced to constitute a post.

To obtain the insulation, it is convenient to choose an insulating material to constitute the T-profiles.

 To be able to make walls of different thicknesses, the sides facing each other have several vertical teeth.

In addition, corner and end elements are provided, one half of which, situated on one side of the vertical median plane, has a hollow square horizontal section the sides of which are the thickness of a wall, the hollows of several elements superimposed constituting a lost formwork for a post made of cast material. In addition, for the construction of the window rebates, the two outer edges of the square section of the corner and end element comprise a vertical square duct with thin walls, the two outer faces of which can easily be destroyed, on request, to form the rebate.

 A final characteristic of the invention consists in providing that the wings of the elements have notches on their lower part, said notches whose axes are common and parallel to the facing. These notches are intended to constitute distribution ribs or chaining between the posts.

Solution to the problem, advantages and industrial result.

Thanks to the device of the invention, the problem of insulation, of making walls of several thicknesses, of the ends of the walls and of the angles as well as the constitution of the rebates for the bays is solved.

 The invention will be better understood with the aid of the following description which is given by way of nonlimiting example and which is illustrated by the attached drawings.

Description of some embodiments.

The walls of the device of the invention consist of basic elements 1, normal corner and end elements 2, corner and end elements for rebate 3, T-sections 4 and mortar that is poured vertically into free spaces for posts 6.

 The prefabricated elements 1 comprise two symmetrical wings 7, 8 which are perpendicular to the facing 9 of the element 1. The sides of the wings 7, 8 which face each other are, according to the state of the prior art, to a quarter of the width 1 of each element; they have teeth 12, 13 cooperating with identical elements, the facing 9 of which is turned on the other side of the wall.

The thickness of the wings 7, 8 is such that it remains within the wall of the free spaces 14, 15 (FIG. 4).

Most of what has just been described is part of the state of the art.

 What is new consists essentially of the assembly of several elements 1 stacked with the aid of a T-shaped section 4 which fills most of the spaces 14, 15, as can be seen in FIG. 2. This section is thread as shown by arrows 16 and 17 in Figure 1.

The rest of the free space which is not filled with the profiles 4 (Figure 2) is filled with a hydraulic binder or a concrete 18 constituting the posts 5. These posts can obviously be reinforced according to a conventional technique.

T 4 profiles can be made of any material. However, it is preferred to make them from insulating material, for example from polystyrene, which considerably reduces the transmission coefficient of the wall thus formed.

Another characteristic of the present invention consists in providing (FIG. 4) wings 71, 81 comprising several teeth 121, 131. These teeth 121, -131 are regularly spaced and arranged vertically so that it is possible to provide several possible spacings d 'elements 11 and therefore several wall thicknesses.

 Another characteristic of the invention consists in providing the corner and end elements 2, one half of which 19 has a hollow square horizontal section whose sides have the thickness of the wall or of the wall. The hollowed-out median part 20 constitutes a lost formwork for a post made of cast material which is poured into the space thus formed. Here, too, the posts can be reinforced with reinforcement.

Yet another feature of the invention consists in providing a special corner and end element 3, part of which 191 also has a square section with a central recess 201 which can be used to form a post.

However, the particularity consists in providing along the two outer edges of the conduits 21, 22 square, vertical, with walls 23, 24 thin. If you want to form a rebate, it suffices, using a blunt tool, to destroy the walls 23, 24.

 The element III shown in FIG. 5 has notches 25, 26 under its wings 7, 8. These notches have a square section and their axis is parallel to the facing.

They are intended to let the concrete pass to form ribs or chaining.
