Facade element holder and method for mounting same

Abstract

A facade element holder includes first and second profile elements, the first profile element having two sections A and B. Here, section A has a first surface shape X and section B as a second surface shape Y. The second profile element has two sections C and D with a first surface shape X′ and a second surface shape Y′. X and X′ and Y and Y′ have substantially the same contour diametrically oppositely in pairs, the spacings from A to B and from C to D being chosen to be substantially equal. The first and second profile elements can thus inter-engage in a form-fitting manner in section A and C and in section B and D. A method for mounting facade elements with such a facade element holder includes providing first and second profile elements and facade elements, and fitting the second profile elements to the rear side of the facade elements and installing the first profile elements horizontally as outer terminating elements of a substructure on a load-bearing building envelope. Individual facade elements are mounted by the second profile element(s) being brought into engagement with the first profile elements such that a form-fitting connection is achieved.

(1) The figures show the invention in various views:

(2) FIG. 1 shows the profile elements 100 and 200 in the unmounted state next to one another, in cross section,

(3) FIGS. 2A-2C show three different stages of joining or inter-engaging two profile elements,

(5) FIG. 4 shows a preferred embodiment of a holder.

DETAILED DESCRIPTION

(6) FIG. 1 shows in cross section, in the left half of the image, a profile element 200 in a state of exemplary connection, via spacing pieces 350, 350′ to a facade element 300. With reference to the image, “upper” or “at the top” corresponds to “upper” or “at the top” in the mounting situation. The upper end comprises the section C, 210, which substantially forms an inverted U. The inner surfaces of the U form the surface shape X′, 211. The lower end of the profile element 200 forms the section D, 220 with the surface shape Y′, 222. D is substantially formed as an L-shaped component. Nevertheless, as indicated by the arrows, the component comprises three surfaces which can contribute to the form-fitting connection. Also included here is the outer terminating surface of the lower leg of the L-shaped component (section D).

(7) Depicted alongside is the mating piece, a profile element 100. It will be clear to the observer that, in the depicted special case, the cross-sectional profile of element 200 represents the profile of element 100 rotated through 180°. However, this is not mandatory, as the comparison with FIG. 4 shows. Analogously to the profile element 200, the profile element 100 has a section A, 110, which is L-shaped in form and, as surface shape X, 111, analogously provides three surfaces at the top. The lower end of profile 100, section B, 120 has the surface shape Y or 121. The formation as a trough (Y, X′) and L-angles (X, Y′) allows adjustment of the two elements 100, 200 with respect to one another during mounting without losing the form-fitting connection. The position of a threaded hole is marked by reference sign 250.

(8) The sequence of drawings 2A to 2C shows the operation of the inter-engagement or the mounting of two profile elements as shown in FIG. 1. FIG. 2A shows how the sections A-C and B-D are aligned with one another, FIG. 2B shows the production of the form-fitting connection, and FIG. 2C shows how the two profile elements inter-engage in the end position. In FIG. 2c, the reference sign 399 (securing element) schematically indicates the position of a screw pin whose under-head thread engages in the profile element 200 and fixes the relative position. The fact that the pin is free from a thread (apart from the under-head portion in engagement with profile element 200) ensures that, in a reversal of the mounting operation, the profile element 200 can be lifted out of the profile element 100 without requiring the screw pin/screwing element 399 to be loosened.

(9) FIG. 2C shows a complete form-fitting connection between the two profile elements 100, 200 without the use of an adjusting screw 500 (FIG. 4). In FIG. 2C, therefore, all three surfaces Y, 121 with Y′, 222 are involved in the form-fitting connection. If an adjusting screw is used, a situation as shown in FIG. 2B is possible. Only 2 of the 3 surfaces are in engagement, with nevertheless the form-fitting connection being effectively achieved.

(10) FIG. 3 explains the construction of a screw pin 400 by comparison with the securing element 399. Starting from the head 440 with a force-application means 450, there adjoins an under-head thread portion 430. Subsequently shown are the thread-free shank 420 and the drill tip 410. The diameter of the drill tip 410 and diameter of the thread-free shank 420 are selected such that they jointly allow pinning.

(11) FIG. 4 shows a perspective view of a partially cutaway configuration of an actual facade element holder. The two profile elements 100 and 200 are in engagement and in form-fitting connection. The adjusting element 500, anchored in a threaded hole of profile element 200, makes it possible, by turning, to adjust the vertical spacing of the two elements without forfeiting the form-fitting connection. The screw pin 400 is shown once as being anchored and once in axial extension from the mounting position.

(12) 600 and 600′ designate two fasteners which could connect the profile element 200 to a facade element (not shown here). This type of connection with the facade element is only one of many possible types.

(13) The features of the invention that are disclosed in the above description, in the drawings and in the claims may be essential, both individually and in any desired, but technically expedient or advantageous combination, for implementing the invention.
