FR2542783A2 - Insulating block of the precast concrete block type - Google Patents

Abstract

The invention relates generally to building blocks intended for building externally insulated load-bearing walls. Insulating block for building blank walls with acoustic and thermal insulation. The block forming the subject of the invention is made from a block of cast concrete, or other material, and of an insulating panel; these two elements are joined together by a reinforcing element made of concrete or other material. The block forming the subject of the invention allows a simple and easy installation which does not require any special tools or skills. This building block makes it possible to construct a load-bearing wall with external insulation by self-centring and self-aligning in a single operation. The invention finds a main application in the construction of thermally and acoustically insulated walls, complying perfectly with the new standards in force.

Description

The invention relates generally to blocks for use in the construction of the breeze block type and more particularly to improvements to the main patent No. 82-19 'applied for on November 25, 1982 in the name of the applicant
In the main patent, a block of the concrete block type has been described, characterized in that it consists, on the one hand, of a load-bearing concrete block serving as a support for the insulating element from the outside, on the other hand , of a thermal insulating plaster support material.

According to a provision of the main patent, this insulating block is characterized in that the carrier block comprises, on the one hand, a honeycomb wall serving as a partition inside, on the other hand, dovetail-like studs, on the other hand finally, vertical reservations arranged in the inner wall of the wall allow the passage of electrical conduits.

The purpose of this addition is to improve the main patent, in particular as regards the assembly of concrete blocks.

To this end, the invention relates to a concrete block according to the first claim of the main patent, characterized in that the two components, namely, the concrete block, on the one hand, and the insulating block, on the other hand, are provided with: '' vertical and horizontal ends allowing assembly on site by self-centering and self-alignment e thus ensuring perfect stability of the construction structure.

The block includes cells (Fig. 1 Ref. 6) to be filled with concrete during the mounting of the load-bearing walls. Recesses (Fig. 1 Ref; 5) are provided in the upper part of the studs (Fig. 2 Ref. 3) in order to ensure good locking of the construction structure.

Embossed key fittings (Fig. 1 and Fig. 2 Ref. 14 A) and hollow (Fig. 1 and
Ref; 14 B) are provided above and below the internal partition of the concrete block (Fig. 1 Ref. 2 and Fig. 2 Ref. 1) in the longitudinal direction.

Horizontal and vertical relief fittings (Fig. 3 Ref. 9) and hollow (Fig. 3 Ref; 15) are provided around the edge of the insulating panel to ensure perfect thermal insulation, as well as. good stability of the construction structure.

Assembly studs (Fig. 2 Ref. 13 A and Fig. 3 Ref. 13 B) allow the creation of a corner block.

The assembly of these two components linked together by tenons (Fig. 2 Ref. 3) and mortises (Fig. 3 Ref. 7) makes it possible to obtain a shuttering block intended for the realization of load-bearing walls insulated by the 'outside.

The installation of these blocks on the site will be done by self-centering and self-alignment thanks to keying tips provided for this purpose.

Claims (1)

 CLAIM Insulating block of the sorting block type, characterized in that the two components are provided with horizontal and vertical keying tips, in relief (14 A and 9) and hollow 14 B and 15) allowing the assembling of the blocks by self-centering and self-alignment.
