Facade fastening system having profile elements

Abstract

A profile element for attachment to the rear side of a faade panel, which in turn is fastened to a base such as a building surface or substructure. The profile element is formed in one piece and includes three functional sections arranged one after another: a fixing section for fixing the profile element to a base; a support section for attachment to the faade panel; and a spacer element which, in the installed state, ensures the correct distance between the base and the rear side of the faade panel. The profile element is extendible by a supplementary element, which has functionally similar elements and is only used if required by the geometry of the faade panel. The supplementary element is usable for positive connection to the profile element of an adjacent faade panel. Such a faade system provides flexibility for a wide variety of types and dimensions of faade panels.

DETAILED DESCRIPTION

(6) FIG. 1 shows a basic configuration of a profile element 10 and a supplementary element 50. Two faade panels 1 (cut away) are spaced apart by a narrow gap 3, the width of which is determined by the engagement of the pin 84 (supplementary element 50) in the groove formed between the edge region 26 of the profile element 10 and the base 5. Profile element 10 and supplementary element 50 are connected to the rear side 2 of the faade panels 1 on the one hand and rest against the base 5 on the other. Base 5 is shown schematically and can represent a building surface or a substructure. The profile element 10 is fixed to the base 5 by means of a fastener 7. Also marked in FIG. 1 is the clear distance d between the facing and opposite surface sections of the fixing section and the support section.

(7) FIG. 2 shows some of the components of the profile element 10. These are, in the drawing from top to bottom, the fixing section 20, the support section 30 and the spacer element 40. The fixing section 20 extends, in the drawing upwards, into the edge area 26, which no longer lies flat on the base 5 like the contact surface 22. The marking 25 marks the plane of the contact surface 22 or of the base 5 in FIG. 2. The groove, slot or pocket 27 is thus formed between the edge area 26 and plane 25.

(8) In the support section 30, the support surface for a faade panel 1 (omitted) can be seen; in the drawing, it terminates at the top with stop means (edge, lug, claw) 36. This function is easily seen in the cross comparison of FIG. 1 with FIG. 2. At the lower end, the support section 30 merges into the spacer element 40, which is simply realized here as a beveled element that helps ensure the distance between the support section 30 and the plane 25.

(9) FIGS. 3 and 4 show a supplementary element 50 that can be used together with a profile element 10. It is of simpler construction than a profile element 10, but has functionally similar sections. In the drawing above, arranged similarly to the intended use, is spacer 60, which has the same functions and limitations as spacer element 40 of a profile element 10. It transitions into a support area 70, which is intended to rest against the lower edge of a faade panel. Similar to the stop means 36, the support area 70 also has a stop edge, stop lug(s) or claw(s) 76 that can determine the relative position of the supplementary element 50 on the lower edge of a faade panel. Further arranged in the support area 70 is the connecting section 80, which opens into a support part 82, which in turn merges into the pin 84. In FIG. 3, various pilot holes/through-holes 52, 52 can also be seen, which can be used for the connection to a faade panel

(10) FIGS. 5 and 6 show a variant of a profile element 10 similar to FIG. 2. The differences relate to the fixing section 20, more precisely the edge area 26, which still forms a pocket or groove 27 with a base 5 or the associated plane 25. However, compared to FIG. 1, the contact surface 22 is reduced in size because part of this surface recedes from the plane 25 earlier than necessary for the groove 27. This forms an additional recess 28, the function of which becomes clear when viewed together with FIG. 5. In the area of the recess 28, a through-hole 24 (oblong hole) and a marking are provided. The recess allows drill chips to be accommodated when setting a fastener and prevents the profile element from being pressed out of the nominal position on the base 5/plane 25 by this drill material. In FIG. 5, predrilled holes 34, 34 can also be seen, which are used for fastening the faade panel/support section 30 via fastening surface 32.

(11) FIG. 7 in turn shows a perspective view of two faade panels 1 from the rear side 2, with a profile element 10 and a supplementary element 50 being in positive engagement with each other.
