Method and a system for fastening an object to a facade

Abstract

A method and a system for fastening an object to a faade comprising at least one supporting wall made in a hard material coated externally with a thermal insulation coat made in a crumbly material, the object being fastened to the wall by means of a fastening member received in an area for receiving a plot made in a hard material arranged in projection out of the wall. The object is fastened to the wall in an indirect way offsetting towards the outside of the faade the area of the plot. The plot is fastened to the wall by a fastening area extending between the wall and the receiving area. The plot is a straight cylinder extending through the insulation coat.

Claims

1. A method for fastening an object to a faade comprising at least one supporting wall made of a hard material being coated externally with a thermal insulation coat made of a crumbly material, the method comprising fastening the object to the wall by means of a fastening member received in a receiving area, and first fastening an intermediary supporting part to the wall before the insulation coat is laid down against the wall and around the intermediary part, the intermediary supporting part being configured to be subsequently cut so that it is flush with the insulation coat, the method further comprising subsequently cutting the intermediary supporting part so that it is flush with the insulation coat, wherein the object is fastened to the wall in an indirect way offsetting to the outside of the faade the receiving area, and the receiving area is fastened to the wall via a fastening area extending between the wall and the receiving area.

2. The method according to claim 1 further comprising arranging the intermediary supporting part on the wall that is fastened to the wall and to which the object is fastened such that the receiving area of the fastening member is offset towards the outside of the faade.

3. The method according to claim 1, wherein the action of cutting the intermediary supporting part is accomplished based at least in part on at least one of a length measuring ruler or precut grooves that are integral with the intermediary supporting part.

4. The method according to claim 1, wherein the action of cutting the intermediary supporting part is accomplished based at least in part on a length measuring ruler and precut grooves that are integral with the intermediary supporting part.

5. The method according to claim 1, wherein the fastening area further includes a cavity for receiving a nut and/or bolt for fastening the plot to the wall.

Description

(1) This invention will be better understood from the following description of the fastening system of this invention, with reference to the appended drawing wherein:

(2) FIG. 1 is an exploded view of a thermally insulated building faade;

(3) FIG. 2 is a perspective view of an intermediary supporting plot of the fastening system of this invention;

(4) FIG. 3 is an exploded view of the fastening system; and

(5) FIG. 4 is a view illustrating the application of the system of the invention to fastening a rainwater pipe.

(6) With reference to FIG. 3, the faade is schematically shown to which an object is to be fastened, being limited to a hard material supporting wall 1 and a crumbly material thermal insulation coating 3.

(7) The fastening system comprises an intermediary supporting plot 9, made in a hard material, fastened to the wall 1 and to which the object to be fastened to the wall 1 will be fastened.

(8) With reference to FIG. 2, the intermediary fastening plot has the shape of a small I-shaped girder, more particularly a two area parallelepiped, with one area 10 for fastening to the wall and one area 11 for receiving at least one member for fastening and adapting to the thickness of the insulation coat 3. The plot 9 is a straight cylinder.

(9) The fastening area 10 comprises, herein the one opposite the other, two small fastening clearances or cavities 12 for receiving each a member for fastening the plot to the wall. In the present case, the base 13 of a cavity 12 is drilled with a through-hole 14 through which a threaded pin 19 fastened to an end 15 by means of an anchoring dowel 16 in the wall 1 can pass and having its other end 17, when the plot 9 is firmly stuck against the wall 1, projecting in the cavity 12 so as to receive a fastening bolt 18 and thus fasten the plot 9 to the wall 1.

(10) The receiving area 11 of a fastening member is also an area for adapting the length of the intermediary plot 9 so as to adapt it to the thickness of the insulation coat 3. Such an area 11 comprises, on the one hand, a length measuring ruler 20 and, on the other hand, precut grooves 21.

(11) The fastening members 22 for the object to be fastened in the intermediary plot 9 are engaged through the end side 31 of the area 11.

(12) The plot 9 is here and preferably made in polyurethane loaded with expanded clay beads.

(13) The object fastening system having been described, the fastening method will be now explained.

(14) Instead of fastening the object directly to the wall 1, it is fastened thereon in an indirect way arranging on the wall the intermediary plot 9 and fastening it through its fastening area 10, extending between the wall and its receiving area 11, by means of dowels 16, before fastening the object to the plot 9 by means, here, of screws 22.

(15) The receiving area of the screws 22 has thereby been offset to the exterior of the faade.

(16) The insulating coating 3 is subsequently laid down. To this end, the insulating panel(s) is/are cut up so as to release a cavity 23 corresponding to the section of the plot 9it is shown on FIG. 3 as a shoulderand the panel(s) is/are laid down against the wall 1 (or against a first coating layer) around the plot 9. The plot 9 projecting out of the external side of the coating 3, its length is adapted and the plot 9 is cut through a precut groove 21 so that, finally, the end side 31 of the plot 9 that should receive the screws 22 is flush with the external side 32 of the insulation coat 3. Thus, the plot 9 can be referred to as being multi-purpose.

(17) Of course, there will be fastened to the wall 1 as many intermediary plots as necessary for fastening all the objects thereto.

(18) With reference to FIG. 4, a rainwater pipe 40 is fastened to a faade, here comprising a wall 1, an insulating coating 3 and an external coating layer 4, by means of a plot 9, fastened to the wall 1 and embedded in the insulating coating 3. The pipe 40 is fastened to the wall 1 by a clamp 42 fastened to the plot 9, in its receiving area 11, via a pin 41. It should be noticed that the plot 9 is flush with the external side 32in fact that of the external coating layer 4, nearly merged into thatof the coating 3.
