- a layer of lightweight concrete mortar few centimeters thick,

the d * - a film coating consisting of cement, a builder. resin and fiberglass, covering one desfaces layer of lightweight concrete,

" sheet material or of a thin and flexible film covering said film coating, and, optionally

- on the other side of the layer of lightweight concrete, with a filmy coating finish reinforced fiber.

Such structure based EJne. has very good physical qualities and sound and heat insulation and allows a low cost and with great ease and rapidity of implementation, many applications to the construction of buildings as well as the natural β * habitatien use of industrial use. Æ

b.' invention also relates to methods of making such a structure as well as the walls or constructs thus obtained.

Other features and advantages of the invention shall become apparent from the description which will follow of several applications such a composite structure, described by way of example only and facing of attached drawings on

Figure 6 illustrates the embodiment - of a construction similar to that of fig. 4 but with framework embedded in the wall, and

- Figure 7 represents a, horizontal section of a vertical wall of the construction of fig. 6.

The composite wall shown in Figure 1 consists of a base layer 1 in concrete mortar lightweight flanked, on one side, with a filmy coating 2 GFP - and, on the other side, with a filmy coating 3 covered itself of a material 4 in thin flexible sheet or film.

The layer 1 has a thickness of several centimeters, for example ten, and consists of a lightweight concrete density of about 250/m in the ky^J a binder composed of foamed cement with special additives and having aggregate various varieties of polystyrene beads.

These beads could be, but 'yield worse, replaced with perlite, aggregate polyurétha' does granulates or other insulators.

This low-density concrete is inevitably very rich binder relative to volume of beads to obtain mechanical strengths increased.

The film coating 2 is a topcoat with fiber reinforced, water repellent and smoothed if desired.

The coating film 3 is a plaster having cement and adjuvant resin. It is glass reinforced processed against the action of alkali cement. There results a high strength fiber cement particularly rigid and tight.

Such a composite structure moves into place according to the following method.

The attempt any ^'d ' first on a framework or supporting structure suitable the sheet or film which is stretched to 4 of carpet.

On this tension support is projected the coating 3, and then, on this coat, 1e concrete house is proji T-<'•could in successive about 5 cm for example up to the oLo nor ion of the desired thickness. Finally, the coating 2 is projected on the neck - derriLer

i-goosefoot.

Fig. 2 illustrates a back many applications possibles.de the technique.

This Figure 2 illustrates the packing-framed, e.g. of a medieval house to be restored.

Is shown in 5 the stud of which is populating the intervals for performing. a wall even epaissor that the trusswork 5.

According to a variant of the above process for this particular application, is applied on the outer face of 1' wooden frame 5 a sheet of a V-C. 6 via a plate 7 for example of plywood, with interposition of a thin layer of soft foam polyether PALs example 8. The plate 7 is for example nailed or tacked to the wooden frame 5.

Then, projected by 1' interior, through the framework 5, 1¹ film coating 9 of about 4 mm of¹ for example thickness, type of the coating 3, the sheet P V 6 corresponding to the sheet 4 of fig. 1.

Then lightweight concrete 10 type concrete 1 is projected in successive layers in the gaps between the wooden frame 5 to be flush with the inner face.

Finally, projected on both the concrete 10 and 1' wooden frame 5 a topcoat 11 high-strength type of layer 2, this layer being planed and smoothed and having a thickness of 5 to 6 mm for example.

After removal of the plates 7 (as well as the foam 8 and the PVC film 6) the outer face of the wall thus reconstructed, as well as the inside, have a finished appearance. The strength of the assembly is excellent and protecting wood 5 provided by the sheet 6 and the coating 11.

The role of the foam 8 is to ensure good contact of the sheet G with the faces of the wooden frame 5 which do not lie in the same plane in particular " because deformations of 1' framework.

This technique is of course applicable to traditional construction with a supporting framework.

According to a variant, after projection of the coating 9, may be placed internally signs of the type 7 leaving passages for injecting into the cavities between the lightweight concrete framework 10. After which, removed the panels and projects the top coating it.

This technique has the advantages of being very quick to implement and inexpensive, in contrast to conventional methods of restoring such walls trusswork. In addition is carried out at the same time excellent thermal and sound while in current techniques restoration must, upon reconstitution of the wall, performing internally doubling with interposition of insulating materials, thereby increasing the cost of as many such restorations.

The fig., 3 illustrates the embodiment according to the invention of a vertical wall having the structure of fig. 1 from a wooden frame consisting of two horizontal rafters 12.

One side of the rafters 12 is secured and tensioned tissue plasticized 13 on the inner face of which, between the rafters 12, 14 is projected a film coating such that the coating 3. Then a lightweight concrete mortar 15 is projected to fill all space between the rafters and, finally, a film coating such that the coating 16 2 or 11 is projected onto lightweight leïïséton 15 and the rafters 12.

This variant of the method of implementation can be extended to any type of supporting framework, both for wooden metal or plastic.

Figures 4 and 5 illustrate the performance of a cell in residential or industrial or agricultural from a single metal frame 17 formed of tubes which are first mounted.

This framework being self-supporting is covered on the outside with a sheet or film 18 (e.g. tissue plasticized]. The fabric 13 is tensioned between the tubes 17 (vertical, horizontal or sloped).

The following layers (19 - 20 - coated concrete coated 21} are put into place in succession in the same manner as above.

The set of the resulting structure is both lightweight, strong and thermally and acoustically insulating.

Can be achieved upon cells of all shapes and sizes.

Apertures may be provided in the wall (e) at any desired location, or by reserving the passages into the fabric 18 using a suitable frame integral or otherwise to the frame 17, or after completion of the structure by cutting the sidewall to the desired dimensions, the wall structure according to the invention being self-supporting.

Figures 6 and 7 illustrate the an alternative technology * fig. 4 and 5 in which the frame 17 is integrated ' in the mass of the composite wall.

To this end, the fabric 18 has hems 22 into which are, threaded tubes 17 which are also optionally provided with corner ' of anyle 23 defining the thickness of the wall, snapped on the tubes 17.

The other layers 19-20-21 are used as above.

^ According as a further alternative of the invention, it is possible to obtain slabs or angle sections which, after assembly, are susceptible to providing ventilation ducts to high fire resistance, as well as some construction (building block, precast slabs with structures semblage aces).

These slabs, angle irons or other elements are made by molding.

Of course, the invention is not limited to the embodiments shown and described above but covers on the contrary all variants in particular with regard to the nature or composition of the different layers 1 to 4 of the composite wall or its various possible applications.
