FR2651816A1 - Method for employing hollow bricks of large dimensions in order to make up, in sandwich form, the outer wall, the insulation and the inner wall at the same time - Google Patents

Abstract

Method for construction and insulation of outer/inner vertical walls, known as "BATI-BRIC". The invention relates to the method for employing well-known traditional materials. It makes it possible to produce simultaneously: the outer wall, the inner wall, the thermal and acoustic insulation, as well as the holding of the assembly, this being of superior quality and at low cost. The method according to the invention is intended particularly for individual or collective construction.

Description

DESCRIPTION
The present invention relates to an implementation process, the particularity of which is to use materials reputed to be traditional, commonly used in construction.

 The basic principle is to replace materials such as concrete block, hollow brick 20x20x40, 20x20x50, or similar.

The process is in the form of a sandwich composed of
- exterior wall: a hollow brick of 0.10 x 0.55 x 0.66
- interior wall: a hollow brick of 0.07x0.55x0.56
0.10 thick insulation separates these two walls, and can be made up of glued solid elements, or of cast elements between these two walls using a whole range of products, such as light concrete, vermiculite in the form mortar, sawdust in the form of mortar, etc.

and in general all materials deemed insulating.

 In all cases of sandwich walls with intermediate insulation, a concrete post of section 0.17x0.20 is recommended every four meters (4m) as well as at each angle, section 0.17x0.20 on each height of floor.

 The upper assembly is linked by a concrete chaining of section 0, lOxO, 2S for full-floor constructions. For repeated storey constructions, the chaining will have the minimum section of 0.20x0.28.

 In the case of individual construction, the hollow brick structure serves as formwork.

In the case of repetitive construction on a building, on the principle of post-slabs, the hollow brick panels replace directly the traditional bricks or concrete blocks
The main advantages of the system are
- use of large products: three per square meter
- the perfect planimetry allows exterior plasters at the pump, rzputrs more economical than traditional plasters and on all interior walls, distribution linings, thickness 0.07, a film coating surfacing ready to paint.

 Significant advantage, all the drawbacks associated with the use of elements such as prefabricated plasterboard, with or without insulation, plasterboard all sections are eliminated, such as for example the attachment of domestic elements which do not poses more particular problems.

 The use of the process brings the advantage of a clean, fast, light, healthy, economical implementation. The setting up of work is facilitated for the user, by the lightening and the volume handled.

 The binder recommended for the exterior walls is "Granicol Rouge (registered trademark) or similar. Its resistance to bad weather is no longer to be demonstrated.

 For interior lining walls, in the case of individual constructions, the binder "Granicol Rouge (registered trademark) is recommended.

 For distribution walls and building lining walls, the binders made available by manufacturers of large hollow bricks have proven themselves.

 In the case of insulation poured over any height in a single operation, the holding of the external / internal walls is ensured by the installation of "Butterfly Threaded Rod" forming an average square of 1.30 ml for concrete, and 1.80 ml for light products.

 The process facilitates the intervention of secondary trades and allows their intervention 48 hours after its implementation.

Claims (3)

 1) Method for the implementation of large hollow bricks composing, in the form of a sandwich, the exterior wall, the insulation and the interior wall at the same time, characterized in that one carries out, in a single operation, thermal and sound insulation by the use, between the two walls formed by the large hollow bricks, of glued elements or elements cast between the walls.  2) Method according to claim 1 characterized in that a concrete post is recommended every four meters, as well as at each angle and on each floor height, the upper assembly being linked by concrete chaining.  3) Method according to claim 1 or 2, characterized in that the hollow brick panels serve as formwork in the case of individual construction, while in the case of repetitive construction on building, they replace the traditional elements.
