System and method for mounting facade elements.

[0001] The invention relates to a system and a method for fixing according to the preambles of claims 1 and 18 facade elements.

[0002] In the market are different fastening systems for facade elements known. But these have the disadvantage, that individual facade elements usually cannot be removed easily, the dismantling of respectively adjacent elements necessary power. In particular photovoltaic panels, which are often also always shuts on building facades, it is necessary, that is able, subsequently exchanging individual defective panels. It can also be necessary, existing behind the photovoltaic modules, exchange defective inverter. A further problem is the wiring of the photovoltaic module, which must be fastened behind the modules separately.

[0003] It is therefore of the present invention, a system for fastening facade elements, in particular clothing elements such as glass sheets or photovoltaic module, to propose a facade, allowing, individual defects exchange facade elements, adjacent elements therefore also without having to be disassembled. Another aim it, provide a fastening system, allowing, facade elements of different sizes and shapes is secure. Another objective is, to propose a fastening system, for mounting the mounting facade elements ranging from strong edges projecting roof or window sills. Another aim is, that the facade elements can be prepared and ready for assembly work, so that these must be secured on the construction only at pre-assembled support profiles. Another objective is, to propose a fastening system, the mounting photovoltaic modules on facades and suitable is designed specifically for the subsequent replacement of modules makes possible also, adjacent modules must be disassembled without. Another aim that a solution to the electric lines of photovoltaic modules is, .

[0004] The invention relates to a system for fastening facade elements, in particular glass panels or photovoltaic modules, at a facade with support sections arranged on a building wall. By connecting means, the rear side of the facade elements can be connected on the one hand and on the other hand with the support rails, the facade elements can be attached to the supporting profiles.

[0005] Invention the connecting means comprise the following components:

- first and second support profiles for substantially horizontal disposition to a substructure of a building wall,

- a guide profile for placement at the back of the facade elements,

- an anchor for releasable positioning on the guide profile, and

a second support profiles can be arranged to be displaceable on the sliding - blank,

- wherein the support profiles, the armature and the sliding blank are formed, to form a first positive connection between the armature and the first support section and a second positive connection between the armature and the sliding handling. The invention fastening system has the advantage, that facade elements are mounted on the support profiles as quickly and as safely, as a facade element are respectively attached to the substructure by means of positive locking below and above. This counteracts the form fit in particular forces, such as wind sucking forces, acting perpendicular to the curtain wall. Only in the horizontal direction is not present form fit.

[0006] The fastening system comprises a third support profile advantageously still, the a combination of the first and second support profile. This allows, for the same profile attachment of two superposed to use facade elements.

[0007] Are expediently for fixing a facade element to the support profiles at least four anchor used. So that the facade elements are each held securely on the support structure.

[0008] According to an especially preferred embodiment are provided a first and second guide profile, wherein the first guide profile for vertical arrangement at the rear of the facade element and a second guide profile for horizontal arrangement at the rear of the cladding panel is designed. The customer has the opportunity to/fitter, to obtain the individual components or all system parts/pre-assembled mounting construction itself, wherein it requires no special tools. Depending on the format of the facade elements one or the other guide profile can be used. For example low but must be mounted very broad facade elements, then the guide profile better than the other is suitable to be arranged horizontally.

[0009] The sliding along a guide longitudinally displaceable in the second supporting section is advantageous handling receivable. This makes it possible, to position the sliding bearing profile already previously blank, blank so that the slide must be moved only compound for the manufacture of form weft.

[0010] Is conveniently by means of a screw pushes the blank, preferably allen screw, fixed on the second support bar. The screw is also present between two superposed by the facade elements, small gap of 6 to 10 mm in readily accessible.

[0011] Advantageously has a U - or hook-shaped foot of the anchor. This can with a rail or projection of the supporting profile of undergoing positive connection, so that the element is secured against Fierunterfallen and wind suction.

[0012] According to a particularly advantageous embodiment of the U - or hook-shaped foot has a stop surface, the facade element with the supporting section as an abutment in a particular pivotal position to note. This has advantages during assembly and for servicing purposes. The facade element such for example for servicing purposes can be pivoted forwardly into a rock position, in which the space behind the facade elements for fitters is accessible from outside. This can be used, for waiting behind the facade elements existing installations (electrical lines, inverter etc) or repairing.

[0013] Advantageously is the same anchor both in communication with the first guide profile and useful in connection with the second guide profile. Characterized in less parts must be kept in stock.

[0014] Preferably is the anchor on the guide profiles on two opposite side is held positively. This makes for a good support of the armature.

[0015] Are advantageously arranged on the guide profile with its foot anchor each outwardly oriented. By the opposite arrangement of the armature, disposed on the bottom edge of the facade element, and those, which are arranged at the upper edge of the facade element, the anchor hooks are each located in the region of the edge of the facade elements, which is an advantage during assembly and accessibility. In accordance with the anchor at a vertically arranged guide profile are each oriented in opposite directions. To the horizontally disposed guide profiles are each oriented in the same direction but the anchor.

[0016] The guide profile has advantageously a clamping groove, in which said one part a fastener preferably is rotatably received. So that the clamping groove is itself the abutment for the fixing means, wherein a portion of the fastener may be a screw or a clamping shoe.

[0017] According to an advantageous embodiment the support sections respectively have two channels, into which a shock profile for connection of two adjacent supporting profiles can be pushed. The problem of thermal expansion of the profiles in the handle can be given.

[0018] The shock profiles in guide grooves are preferably held positively. Contact for the shock profiles interconnected support profiles can not twisting relative to one another. The shocks of the support profiles can be at any point.

[0019] The object of the present invention is also a process for preparing a facade elements formed from individual building facade, wherein the facade elements on supporting profiles, the turn take a building substructure are arranged, are fixed. This method is distinguished in the invention, at the rear facade elements guide profiles are fixed with anchors, that support profiles are fixed to the building wall a distance substantially horizontally, by means of that the facade elements are suspended from a support bar and a first lower anchor made positive connection is, and the facade element is realized by means of a longitudinal direction of the supporting profile then at an upper support on the support rail Schieblings arranged a second form-locking connection. This production method is especially advantageous, because the facade elements can be mounted easily even by a person.

First the spacer (not shown) are screwed to the building wall 139 and the insulation (not shown) then applied. Thereafter vertical mounting rails are mounted on the spacers 141 139. 141 To the mounting rails the support profiles (step 2) are then mounted 21.25 at predetermined intervals. The facade elements 13 with the guide profiles 17 are prepared on site and factory at the lower supporting section 21 (step 4 suspended into figfig. 14). The facade element on the supporting section 25 is prepared thereafter pivoted and the form fit between the shift 77 and the armature 19, the former is displaced along the support profile by and engaged with the anchor 25 19. Thereafter the shift 77 is fixed to the carrier profile still, a fixing screw is screwed into the bore by 85.

[0042] The figfig. 15 to 17 show an alternative embodiment of a guide profile 147 and 149 to a mating anchor. First embodiment of the invention described above for essential difference that the guide profile 147 has a longitudinal clamping groove 151, in which the armature is 149 is attachable, . This embodiment has the advantage, that the armature 149 must be pre-assembled at the factory need not, but can still be mounted on the building site or offset.

[0043] Since the armature 149 and the same as the anchor 17 has further functionalities, were for the description of the same effect as with the same reference symbols as used features each anchor also has a base plate 17 of the armature 147 17th anchor 93, 93 integrally formed on the front side of the base plate a channel 97, external to the channel wall and spaced from the end face of the base plate 105 103 a chamfer 93 109 a chamfer. In connection with the undercut 99 of the channel 93 a with the guide profile 147 149 and the armature 13 at an angle to the plane carrying facade element can be looped the curtain wall at a lower supporting section 21. The same aforementioned technical characteristics allow further pivoting of the facade element, wherein said chamfer 109 and optionally the bevel 105 serves as a stop surface (s) in one extreme position.

[0044] The armature 149 is equipped with an adjusting screw 152, the 113 115 is provided in a bore in the channel base.

[0045] Unlike the base plate 93 of the anchor after the anchor 17 has a shoulder 153 and a chamfer 109 147 still adjoining, tapered guide portion 155. This can further cooperate with a guide groove of the guide profile described below (see description below figfig. to 20) horizontal. Two round holes are provided 155a and 155b in the base plate, a lock screw 157 (figfig. 15) intended to contain. Depending on the lock screw must be 147,157 coming for use either in the central guide profile round hole 155a (vertical guide profile, p. figfig. 15) or in the round hole 155b (horizontal guide profile, p. figfig. 20 below) used.
