BRIEF SUMMARY
SUSPENDED SURFACES FOR THE APPLICATION OF PLASTERS
The present invention relates to a method for the suspension of panels from a building to form a final surface, on which plasters are to be applied.
According to the art of building construction, as reported in the pertinent literature, the plasters are applied on the walls as follows:
a) Directly on the surface of the main wall.
b) On surfaces of materials, which are directly attached to the single leaf walls, as for example on plates of insulation materials, metallic screen etc.. In the case, where plates of insulation materials are used, before the application of plasters the plates are reinforced with metallic, fiberglas or plastic screens.
c) Directly on the surface of the exterior wall, in the case of twin leaf walls with an air gap, four to six centimetres wide, between the two leafs, whereby the air gap may be filled with insulating material. It should be noted, that due to its small thickness, the brick wall constituting the exterior leaf, must be supported to the inner wall with ties and with concrete beams.
Further, document WO-89/01550 discloses a method to construct a surface covering a wall using brackets, which are mounted in a dense arrangement on the wall. In particular FIG. 15 of this document shows the rows of brackets 149 screwed in the wall, with insulating material 150 being suspended on the horizontal portion of the brackets. Subsequently beams are inserted into the hooks of the brackets to anchor the insulating material, and facade sheets 157 are attached by rivets on the outside of the beams in the way shown in FIG. 10 of the WO-document. With such a construction an air gap is formed between the insulating material and the facade sheet. It is noted that according to this method of construction the brackets transfer the loads which act on the panels, to the wall. Further the depth of the air gap thus formed, depends on the dimension of the web of the beams (see FIG. 10 of WO-document, beam 128) and subsequently the dimensions of the beams must be selected according to the thickness of the insulating material and the thickness of the air gap.
It would be desirable if there were available a method and the necessary means for the construction of panels covering the walls of the building, whereby the construction is on one hand simple and not time consuming and on the other hand the loads acting on the panels do not dangerously load the walls of the building.
The present invention provides a method for the suspension of panels from a building, to form a final surface, on which plasters are to be applied, whereby the building consists of a load bearing structure and a curtain wall and has an outer surface, which faces the panels, and which is covered with an insulating material. In accordance with the invention, supports made of non-rusting material are clamped on the load bearing structure of the building, to form at least one horizontal array of supports, whereby the supports project from the outer surface of the building and from the insulating material. The supports of each of the horizontal arrays are bridged by at least one beam-member made of non-rusting material, whereby the connection between the supports of each horizontal array and the beam-members bridging the supports allows the beam-members to slide on the supports, so that to avoid the development of stresses in the beam-members as a result of temperature variations. At least one comb element having teeth connected to stop means, penetrates the insulating material, to locate the comb element, so that the stop means projects from the insulating material. Then the panels are hung on the beam-members, in such a way so that adjacent panels overlap, whereby the stop means form an abutment for the panels to maintain them at a distance from the outer surface, the distance exceeding the thickness of the insulating material so that an air gap is formed. Finally the overlapping areas of the adjacent panels are fastened to each other, to form the final surface, on which the plasters
