pOM.r; INSULATING CARRIER WALL FOR PREFABRICATED CONSTRUCTION.

i; 1 The invention relates to a prefabricated load-bearing wall. Of thermal insulation which is advantageous in relation to its | thickness, designed in particular for electric heating. j I 1 The use of electric heating involves,

I I

'5 for reasons of savings a high degree of insulation. 1 i '

These insulation standards imposed by law in, "j in the case of electric heating are advised and frequently! J adopted by builders in residential construction! I '1 tions, including individual houses whatever the mode ji : 10 and heating energy.

: In traditional houses, it happens in; I; core that the contractors adopt interior insulation by “interposition of insulating plates taken between the external walls' and against partitions.

^ 5 This solution, which is very costly in terms of manpower and materials, is completely out of date today and therefore rarely used. We prefer insulating panels with a finished surface on the inside. In the prefabricated house, it is not possible to design or .20 provide for structural work outside the basic assembly. The insulating layer must be integrated into the wall or 1 section of wall at the time of manufacture.

In prefabrication, floors have already been made thermally insulating by bonding a layer 25 of insulating material on the underside.

Prefabricated insulating walls also exist. These walls are formed of insulating material attached to the interior faces.

The integration of the insulation into the walls is not resolved correctly at all, which does not guarantee that the insulation will be maintained over time.

In addition, the problem of the continuity of the insulation at the right of the junctions and the means of assembly is badly regulated.

35 There are indeed undesirable thermal bridges, generally of large extent.

The insulation breakage thus created causes inconvenience in terms of comfort and aesthetics because it generates the formation of cold zones, but also points of weakness and cracking in the construction. j, _ _ t 2

The prefabricated wall according to the invention provides appreciable improvements in the insulation of individual houses and.

"To their construction.

| It is remarkable for its composite structure in ar- i i. ; 5. - ches and intermediate plate with dense reinforcement combined with two lattices of interior wall and facade panel ensuring: a great overall mechanical resistance and a homogeneous insulation. ; '. This wall simultaneously has a coefficient of insulation: i 1 interesting thermal jio tion, below the minimum required for! electric heating and great homogeneity of insulation.

This double characteristic brings the feeling of desired comfort. The assembly technique used ensures rapid and careful i .15 mounting.

Furthermore, this wall and the construction thus produced offer all the guarantees of solidity and maintenance of its quality over time. j

The cracks no longer appear at the right of the rushes.

20 connections and connections. Despite its relatively small thickness for a load-bearing wall, it has very remarkable sound insulation qualities. It reconciles the requirements of solidity and lightness which are particularly sought after in prefabricated construction.

The following description highlights all the technical characteristics of the invention. This is done by way of nonlimiting example with reference to the drawing (attached in which: * - Figure 1 is a perspective view of a section of wall i30 according to the invention; - Figure 2 is a cross-sectional view on the current part of the prefabricated wall shown in FIG. 1; FIG. 3 is a cross-sectional view of the lifting and hooking loop of the external slab; FIG. 4 is a vertical sectional view of two walls assembled vertically for the manufacture of two levels; 40 - Figure 5 is a perspective view of the same assembly-> • 'y 3, Sjf * · * yr wiring showing the connection plates and the V chaining; ... ....

The prefabricated wall according to the invention has the general configuration as illustrated in FIG. 1.

It is called upon to constitute the external walls of an individual house, at the height of the floor.

v Its transverse profile consists of a succession of open rectangular arches • 15 such as 1, extending over the entire height of the wall.

It ends on the edge of the wall with a groove 2 with a flat bottom of prof 11 - in - • "-y ··"! ··· £ o-rroan-t — cof .f-gage-.po.ur- I - 3jQijxt - of ______ sealing 3 in concrete.

20 Each edge comprises, over the entire height of the wall to the right of the grooves 2, on the outside, a rectangular recess 4 provided with a connection plate 5.

The arches 1 delimit with a closure plate 6 on the outside of the cells 7 filled with insulating material 8 such as expanded polystyrene, or empty wine.

The wall has a dense reinforcement formed of metallic rods 9 vertical at the level of the feet 10 of the arches 1 connected together by horizontal crosspieces arranged at regular intervals over the entire height of the wall. These crosspieces 30 are interconnected by external vertical rods embedded in a concrete plate 12 forming the external face.

This plate is internally reinforced with a metal mesh '·.' An analogous trellis 14 arms the front face.

A pair of horizontal rods such as 15, made of steel, known under the name TOR for example with a diameter of 8 mm, reinforces the wall according to the invention at the top and bottom.

This wall has at the end of each arch foot or each arch of even rank a lifting loop such as 16 secured to the inner frame for handling 40 and the establishment on site.

cm J II-has a smooth interior wall ready to receive! I the wall coverings and a uniform exterior face for the! j! J projection of an external coating.

The prefabricated insulating wall thus formed has a total thickness of 25 cm.

This thickness is the smallest that we know for load-bearing walls of individual houses.

{I After describing the general structure of the object wall

J I

! | of the present invention, we will examine its connections with jtO! the floor element, with the foundations, with the upper wall j! and its anchoring on the frame.

! | j These characteristics are shown in Figures 4 and: t 5.

In a second step, we will describe the horizontal L5 assemblies.

The vertical section 4 reveals in the upper part an anchor bolt 17 fixing the frame 18 secured to a (! Upper plate 19 provided in the upper part of the wall, or sealed in the inner wall of the element.

2o The connection between two vertical elements is ensured by a self-adhesive compression joint 20. The vertical immobilization is carried out by an element plate 21 anchored in the lower part of the wall and by a metal chaining plate 22 or foundation 23 secured to each other by welding. The 25 chaining plates or foundations are immobilized by a hook 24 taken in the mass.

The junction between the bearing wall and the first floor is made by pouring a perimeter in the form of a concrete beam 25 forming chaining.

3o ‘Immobilization results from the interweaving of steel rod frames. At least one longitudinal chaining frame 26 passes through the lifting loops 16 of the load-bearing walls and the similar lifting loops 27 of the floor elements 28.

The horizontal assemblies are of the bolt-on type 35 with bolts such as 29 and concrete sealing joint 3.

The assembly is completed on the interior side by the soli-darization of the vertical plates 5. These have, to the right of the partitions, a metallic reminder 30 in the form of an additional plate 31 strongly anchored on the partition walls. 40 The assembly at angles 32 is carried out in a similar way cm j j by bolting and forming a sealing joint in! i concrete.

i ·> •: The technical configuration at the end of the wall is i as shown in FIG. 8. The connection by 5 plates takes place in the corner of the recessed part 33.

The section on window shown in FIG. 9 shows J the particular structure of the wall according to the invention at level j | an opening to the outside. It comprises in the lower part j · shapes in profiles of the water jet type 34 and 35 and in! ! jlO j upper part a beam 36 and an upper structure 37 î j! comprising a special frame 38 forming a lintel, j J j The last figure represents the junction of a wall element with the ceiling. An annex profile 39 supports by its perimeter a layer of plaster in canvas 40. The upper part is strongly insulated by means of several layers 41 of insulating material.
