Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will be explained in greater detail on the basis of preferred embodiments that are schematically depicted in the accompanying figures, whereby individual features of the embodiments presented below can be implemented in conjunction with the invention either individually or else in any desired combination. The figures show the following schematically:

(2) FIG. 1: a first embodiment of a console according to the invention, in a perspective view;

(3) FIG. 2: a detailed view of the console according to FIG. 1, from the side; and

(4) FIG. 3: a second embodiment of a console according to the invention, in a perspective view.

DETAILED DESCRIPTION

(5) Identically functioning elements are designated by the same reference numerals in the figures.

(6) A first embodiment of a console according to the invention is shown in FIGS. 1 and 2. The console has a wall part 1 that is mounted on a building wall 100, a faade part 2 that is mounted on a faade, as well as a bridge part 3 that mechanically holds the faade part 2 on the wall part 1, thereby creating a heat barrier between the wall part 1 and the faade part 2.

(7) The wall part 1 has a mounting plate 19 that lies flat on the building wall 100, and a plate element 11 which projects from the mounting plate 19 at a right angle and on which the bridge part 3 is arranged. The faade part 2 likewise has a plate element 21. The plate element 21 of the faade part 2 is supported by the bridge part 3. In this context, the plate element 21 of the faade part 2 runs paralleland coplanar in the embodiment shownto the plate element 11 of the wall part 1.

(8) The plate element 11 of the wall part 1 has two opposing flat sides 12 and 13, two opposing narrow lengthwise sides 14 and 15 as well as a narrow, free end face 16. The plate element 21 of the faade part 2 likewise has two opposing flat sides 22 and 23, two opposing narrow lengthwise sides 24 and 25 as well as a narrow, free end face 26. The free end face 26 of the faade part 2 and the free end face 16 of the wall part 1 face each other as well as the bridge part 3.

(9) When the flat sides 12, 13, 22 and 23 and/or the end faces 16 and 26 have been properly installed, as a rule, they run vertically, that is to say, the lengthwise sides 14 and 24 are above the lengthwise sides 15 and 25, respectively. Fundamentally, however, installation in which the flat sides 12, 13, 22 and 23 run horizontally or obliquely is also possible.

(10) The bridge part 3 is an injection-molded part made of fiber-reinforced plastic. It has a first, preferably upper, support flange 31, and a second, preferably lower, support flange 32. The two support flanges 31, 32 run at a distance from each other, preferably in the horizontal direction, each from the wall part 1 to the faade part 2, and they join the faade part 2 to the wall part 1. In this context, the two support flanges 31 and 32 of the bridge part 3 are injection-molded around the wall part 1 and the faade part 2 so as to encapsulate them. Each one of the two support flanges 31 and 32 is in contact with the two flat sides 12 and 13 of the wall part 1 and with the two flat sides 22 and 23 of the faade part 2. Preferably, the first support flange 31 can also be in contact with the lengthwise side 14 of the wall part 1 and the lengthwise side 24 of the faade part 2, and/or the second support flange 32 can be in contact with the lengthwise side 15 of the wall part 1 and with the lengthwise side 25 of the faade part 2.

(11) The bridge part 3 also has four bars 35, 36, 37, 38 which are joined together by means of the two support flanges 31, 32 and which stiffen the two support flanges 31 and 32 with respect to each other. The four bars 35, 36, 37, 38 form a cross shape and run in a parallel, especially coplanar, plane to the plate elements 11 and/or 21, whereby the intersection area of the four bars 35, 36, 37, 38, in other words, the area where the four bars 35, 36, 37, 38 meet, is situated in the center between the two support flanges 31 and 32. The four bars 35, 36, 37, 38 and the two support flanges 31 and 32 are configured so as to be mirror-symmetrical to a plane that is perpendicular to the cross shape of the four bars 35, 36, 37, 38 and that runs between the two support flanges 31 and 32 (in FIG. 2, this plane of symmetry is perpendicular to the drawing plane and runs from left to right). The four bars 35, 36, 37, 38 and the two support flanges 31 and 32 are also configured so as to be mirror-symmetrical to another plane of symmetry which is perpendicular to the cross shape of the four bars 35, 36, 37, 38 and which intersects the two support flanges 31 and 32 (in FIG. 2, this second plane of symmetry is perpendicular to the drawing plane and runs from top to bottom).

(12) The gate mark 40 of the bridge part, in other words, the area where the fiber-reinforced plastic material was fed into the mold during the injection-molding process, is located in the intersection area of the four bars 35, 36, 37, 38. In the four bars 35, 36, 37, 38, the preferential direction of the fibers of the fiber-reinforced plastic material is approximately parallel to the appertaining bar, as indicated by arrows in FIG. 2.

(13) In the plane of their cross shape, the four bars 35, 36, 37, 38 enclose four fields 41, 42, 43, 44, namely, two diametrically opposing crosswise fields 41 and 42 that, starting from the intersection area of the bars 35, 36, 37, 38, open towards the support flange 31 or the support flange 32, and two diametrically opposing lengthwise fields 43 and 44 that, starting from the intersection area of the bars 35, 36, 37, 38, open towards the wall part 1 or the faade part 2. The crosswise fields 41 and 42 have a smaller opening angle than the lengthwise fields 43 and 44.

(14) In the embodiment shown, the fields 41, 42, 43, 44 are not filled with plastic material and they each form an opening. However, the fields 41, 42, 43 and/or 44 can also be filled with plastic material. The following then preferably applies to the material thicknesses: 0abc, wherein a stands for the material thickness in the individual lengthwise field(s) 43 and/or 44, b stands for the material thickness in the individual crosswise field(s) 41 and/or 42, and c stands for the material thickness in at least one of the bars 35, 36, 37, 38, preferably in all of the bars.

(15) This relationship is not limited to the embodiment shown in FIGS. 1 and 2, but rather, can also be employed for other geometries according to the invention.

(16) The console shown in FIGS. 1 and 2 especially can withstand the force F1, for example, the wind force on the faade and the force F2, for instance, the force of the weight of the faade.

(17) Another embodiment of the console according to the invention is shown in FIG. 3. The embodiment of FIG. 3 implements a number of features of the embodiment from FIGS. 1 and 2 in an analogous manner, so that the above-mentioned description can be employed analogously and only the differences will be elaborated upon below.

(18) The support flanges 31 and 32 in the embodiment of FIG. 3 are structured. They have struts and depressions located between the struts.

(19) The crosswise fields 41 and 42 in the embodiment of FIG. 3 are completely filled. In the lengthwise fields 43 and 44, there are struts 53 and 54 that adjoin the intersection area of the bars 35, 36, 37, 38 and whose material is thinner than that of the bars 35, 36, 37, 38. Moreover, the lengthwise fields 43 and 44 have openings 45 and 46. The strut 53 is located between the opening 45 and the intersection area, while the strut 54 is located between the opening 46 and the intersection area. The surface area of the strut 53 is smaller than the adjacent opening 45, and the surface area of the strut 54 is smaller than the adjacent opening 46.

(20) In the embodiment of FIG. 3, the plate elements 11 and 12 of the wall part 1 and the faade part 2, respectively, have a ribbed structure 18 and 28, on which the bridge part 3 is joined to the wall part 1 or to the faade part 2. The mounting plate 19 of the wall part 1 has a hole through which an anchor bolt can be inserted in order to anchor the mounting plate 19 to the building wall. The faade part 2 of FIG. 3 has a holding clamp 70 that is arranged on the plate element 21 of the faade part 2. During the installation procedure, a support profile 101only shown in rough schematic form in sectionsof the support profile structure of the faade can be held temporarily by clamping between the holding clamp 70 and the plate element 21. In the plate element 21 of the faade part 2, there are openings that allow the temporarily clamped support profile 101 to be permanently screwed to the faade part 2.
