  The present invention relates to the field of thermal insulation of buildings from the outside and more particularly to a small insulating element of facade cladding and its application to the realization of a

vUture process.

  Current insulation techniques for the exterior of buildings generally involve either the installation of an insulation on the wall and then an exterior protective and finishing coating, or the laying of an insulation and then a external skin protection maintained by a secondary frame attached to the wall by means of legs, clamps ... secured to the carcass work by a mechanical attachment of the ankle type. All these processes

  costly because of a multitude of tasks to be carried out on the

  during the installation, research has been carried out in recent years on prefabricated insulation-outer skin complexes, which can be glued

  and / or mechanically attached to the outer support wall to be protected and assembled.

  Wheats most often with live joints by clipping. These complexes, which are more commonly known as vetures, usually consist of a skin

  associated with an insulator, each element of clothing generally covering

  large areas of the order of m2 or more.

  Despite the large number of studies carried out on the subject and the proof of which is offered to us by the numerous patent applications filed in France in particular, it turns out that these products have difficulty to impose on the market as a result of a part of the difficulties of adaptation of the products to all the cases of figure encountered to isolate the facades of a building, and on the other hand of the presence of multiple fixings more or less easy to implement and which strain the price posed insulating coating. As a result, veture elements of smaller dimensions have recently appeared, ie covering small areas (SC 0.25 m 2), and which give more flexibility to the installation, in particular for the production of bay frames. However, the different models currently proposed still impose

  several fastening points per element, whether mechanical fasteners or

  nails or sticks of glue. The purpose of the present invention is to remedy

  these disadvantages by proposing a small insulating element for

  building facade, which has a simple structure, a single maximum point of attachment to the support wall, excellent insulation without thermal bridge and which, once installed, gives the insulated wall the appearance of a traditional coating says ordinary vertical light. The said small insulating element of facade cladding is characterized in that it comprises two parts constituted, the first of a rigid, protective and decorative outer skin plate, and the second of an insulating core shaped T glued on the underside of the outer skin plate and such

  so that the underside does not have on its lower periphery.

  Preferably, the insulating core is made using a rigid insulator

  expanded polystyrene or injected polyurethane, while the outer skin

  re is fiber-cement-silica autoclave. In addition, the T-shaped core is provided at mid-thickness, over the entire length of its slices, with a system of male and / or female rabbets as the case may be, and characterized in that the longitudinal slices of the insulating core

  are provided on the part corresponding to the lateral wings of the sheet T

  female lures and on the part corresponding to the foot of the rabbet T

  males, and in that the transverse slices of the insulating core are

  views on the part corresponding to the vertex of the T of a male rebate, on the part corresponding to the middle of the T of the rebates females and on the part

  corresponding to the base of the T of a female rabbet.

  The invention also relates to a cladding method made from the small insulating elements described above, characterized in that the said

  small insulating elements allow the realization of a clear coating.

  vertical normal way, that is to say that the outer skin plates are arranged in vertical rows in which each upper plate partially covers the respective lower plate, the contiguous vertical rows being continuously offset from each other by a distance corresponding to half of the difference between the height of the outer skin plates and the overlap within said rows, the outer skin plates of the neighboring rows overlapping partially longitudinally, each plate being inserted between

  two adjacent plates of the adjacent row considered. Thanks to this agency

  As well as the shape and layout of the T-core of the small elements, the simple and close fitting of the male and female rabbets of the various small elements, at the same time a continuous thermal insulation of the wall, a waterproof protection of the insulation and wall, as well as the possibility

  to use at most one fixation per element.

  According to another characteristic of the invention, the vature is fixed at

  wall with a nail-peg assembly inserted into the single hole

  at the top of the element and in the median axis, ie in the zone

  corresponding to the transversal overlap between two small adjoining

  cent in the same vertical row, so that no fasteners are

  rent once the coating is finished. This arrangement significantly improves the aesthetics of the coating while avoiding the problems inherent in the

  - 3 - corrosion of mechanical fasteners (nails, screws or the like) left behind

  apparent and therefore directly exposed to bad weather.

  Other features or features of the present invention

  will appear on reading the following description of a non-example

  limiting with reference to the appended figures among which: FIGURE I is an elevational view of the front face of a small element

  FIGURE 7 is a side elevational wall-support view of the breeding process. FIG. 8 is a section along C C. FIGURE 9 is a section along D D. As shown in FIG. 1, the small building facade cladding insulation element comprises an outer skin lacquer (1) made

  in this example in Glasal - (fiber-cement-siliceautocla-

  vé, compressed) of thickness 4 mm and format 60 X 30 cm; this material having the particularity of being permeable to water vapor, of great dimensional stability, and having on the surface an aesthetic and durable colored coating. On the underside of the plate (1) is fixed either by bonding an insulating core (2) of polystyrene, or by self-adhesive insulating core (2) polyurethane, one or the other having the particularity of being T-shaped so that the underside of the plate (1) is devoid of insulation on its lower periphery, that is to say in the area (3) of

  transverse and / or longitudinal overlap between adjacent elements.

  The insulating core (2), and as shown in Figures 1-2 and 3, overflows

  slightly above the plate (1) the value corresponding to the thick-

  with a small rabbet (4 '). It will be noted in FIGS. 2-3-4-5 that the insulating core (2) is provided at mid-thickness, over the entire length of its slices and alternately, male rabbets (4-4 ') and / or females (55'-5 ") as appropriate to ensure self-locking.between contiguous elements and allow the maximum use of one fixation per element.This fixation is made through the hole (6) located at the head of

  forming outer skin and insulating core. -

  FIGS. 4 and 5 show two sections of the insulating core (2) at the AA section of the upper half of the T-core and at the BB section of the lower half of the T-core. on the AA cut the presence of two female rabbets (5), while on the BB cut the presence of two

rabbets (4).

  This arrangement allows, on the one hand vertically to the male rabbet (4) of an element of a row considered to become positioned in the female rabbet (5) of the adjoining element of the adjacent row and vice versa, and other horizontally to the female rabbet (5 ') of an element of a row considered and to the female rabbets (5 ") of the two contiguous elements of the two adjacent rows, to be positioned in the male rabbet (4')

  of the lower element of the same row considered.

  For the realization of the cladding method according to the invention, the external skin of which is laid down with ordinary vertical skylight and using small insulating elements as described above, the following procedure has been followed. and as shown in FIGS. 6 and 7. Firstly, a small standard element (7) and a "doubling" element (8) are alternately placed on the same level line, the latter corresponding substantially to the part completely covered with insulation on the underside of an outer skin plate (1), increased by a band of 2 to 6 cm without insulation and acting as a drop of water. Once this first rank is achieved,

  standard elements (7 ') of the lower rank are interlocked in the cre-

  formed in such a way that the insulating islands (2-2'-2 ") of the different ranks are perfectly interwoven with one another and so

  that the outer skin plates (1-1'-1 ") have after covering

  longitudinally and transversely the traditional configuration of scales

  laid with ordinary vertical light.

  As shown in FIG. 8, the fastening made at the top of the elements and which is invisible on the first row of standard elements (7) because of the transversal overlap of the upper elements (7 ") makes it possible to avoid

  any direct attack of the ankle-pin package (9) by the atmospheric agents

  and improves the aesthetics of the facade cladding.

  FIG. 7 has been shown to improve the understanding of the rear side on the wall-support side of the cladding process, it being understood that this

  face is not apparent in the reality of the work because intimately solidari-

  wall-mounted. This figure shows the perfect interweaving of souls

  insulation (2-2'-2 ") and the resulting continuity on the insulation plan.
