Abstract

The prefabricated construction elements comprise a freely expandable reinforced concrete outer wall (1) which is fixed (2) on an internal reinforced concrete bearing wall (3). Between the two concrete walls is a thick, continuous layer of thermally insulating material (4). An Independent claim is included for a method of building construction from the elements.

Description

The present invention relates to precast molded concrete elements

including a

  equal thickness of thermal insulation and a building construction method using these elements.

  Buildings of this type are generally designed to be thermally insulated, but it can be seen that the thermal insulation is not regular, it is either interrupted or reduced in terms of the chaining of the floors, of the partition walls, at the level of the design. or at the junction of the elements, which affects the insulating function of the construction. The object of the present invention is to remedy these drawbacks by providing prefabricated molded panels with high incorporated thermal insulation, of equal thickness, external to the load-bearing structure of the construction, without any interruption or reduction of the material.

thermally insulating.

  The subject of the invention is in fact a molded prefabricated panel comprising a layer of thermally insulating material, of equal and continuous thickness, capable of coming into contact with

  all layers of insulating material from neighboring panels.

  According to a preferred embodiment, the panels consist of an outer wall of reinforced thin concrete, freely expandable, fixed to an inner wall of reinforced concrete thick. They are located on either side of the thick layer of material

  thermally insulating, the 2 concrete walls being designed to be at their ends slightly set back from the insulating layer to ensure the contact of the latter with the layers of insulating material of neighboring panels.

  Each of the elements thus formed therefore constitutes both an external member supporting the facade coatings, a thermally insulating material of equal thickness capable of entering

  in contact with neighboring insulating materials, an internal member carrying the construction.

  The invention also extends to the construction method formed using the above elements.

  Each panel comprises, at the two ends of the concrete load-bearing wall, a cavity with, in waiting, reinforcement in the form of a loop. These cavities allow the realization, during the implementation of the panels, of connecting cores connecting the elements together ensuring, on the one hand, the cohesion and solidity of the structure, and on the other hand, the continuity of the layer

  of thermally insulating material outside the building support system.

  The description, below, of an embodiment given by way of example, without limitation and

  shown in the accompanying drawings, will also highlight the advantages and characteristics of the invention. On the drawings

  As shown in these drawings, the element (6) is a sandwich panel which comprises a layer of thermally insulating material (4) fixed between two thicknesses of reinforced concrete (1) and (3) respectively. The outer wall (1) which is formed of a relatively thin concrete thickness, is

  the support for facade coverings, while the interior concrete wall (3) which is significantly thicker forms the support member of the construction.

  The outer wall (1) is adjacent to the layer of insulating material (4) and slightly set back (11) at its vertical ends from the layer of insulating material (4) to facilitate its contact with the layers of material insulating adjacent panels. The inner wall (3) is

  also recessed at its vertical ends from the layer of insulating material.

  The thick inner wall (3) is close to the layer of insulating material <4) and has at its

  2 vertical ends a cavity comprising reinforcements, pending, in the form of a loop (9).

  During the implementation of the panels, [Us cavities are drowned in concrete, after putting in place the vertical anchoring frame (8) placed between the loops (9), waiting, thus forming the

  connecting cores (5) which ensure the consistency and solidity of the construction (10).

  According to a preferred embodiment, the external wall (1) is held integral with the internal wall (3) by means of reinforcements in the form of pins and lines (2) which pass through the layer

thermally insulating (4).

  As shown in these drawings, the layer of thermally insulating material (4) of the various panels is in contact with all the other layers of insulating material (7), horizontally

  and vertically, constituting an insulating envelope.

  Consequently, when the elements are in place, they provide continuous and regular thermal insulation external to the load-bearing structure of the construction, even at the level of chaining and splitting.

  A construction is thus obtained which ensures regular thermal insulation while retaining

  ease of assembly and rapidity of execution usual in constructions of this type.
