Description

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

PRIOR ART Various fastening systems for facade elements are known on the market. However, these have the disadvantage that individual facade elements usually can not be removed so easily, respectively. makes the disassembly of adjacent elements necessary. Especially with photovoltaic panels, which are increasingly installed on building facades, it is necessary to be able to subsequently replace individual defective panels. It may also be necessary to replace existing, defective inverters behind the photovoltaic modules. Another problem is the cabling of the photovoltaic modules, which must be attached separately behind the modules.

Object of the invention The object of the present invention is therefore to propose a system for fastening facade elements, in particular of clothing elements such as glass panes or photovoltaic modules, on a façade, which makes it possible to exchange individual defective facade elements, without therefore also dismantling adjacent elements Need to become. Another object is to provide a fastening system that allows to fasten facade elements of different sizes and shapes. Another goal is to propose a mounting system that assemble the assembly of facade elements in the area of highly projecting roof edges or window sills. Another goal is that the façade elements can be prepared in the factory ready for installation, so that they must be attached to the building only on pre-assembled support profiles. Yet another goal is to propose a mounting system that is especially suitable for the installation of photovoltaic modules on facades and also makes the subsequent replacement of modules possible without the need for disassembling adjacent modules. Another goal is to find a solution for the electrical cables of photovoltaic modules.

Description: The invention relates to a system for fastening facade elements, in particular glass panes or photovoltaic modules, on a facade with support profiles arranged on a building wall. With the help of connecting means, which are connected on the one hand to the back of the facade elements and on the other hand with the mounting rails, the facade elements can be attached to the support profiles.

According to the invention, the connecting means comprise the following components: first and second supporting profiles for substantially horizontal arrangement on a substructure of a building wall, a guide profile for arrangement on the rear side of the facade elements, an anchor for detachable arrangement on the guide profile, and a displaceable one - The support profiles, the anchor and the slide are designed to form a first positive connection between the armature and the first support profile and a second positive connection between the armature and the Schiebling. The fastening system according to the invention has the advantage that facade elements are mounted quickly and securely on the support profiles, since a facade element is attached to the substructure at the bottom and top by means of positive locking. In this case, the form-fit counteracts particular forces, such as wind suction forces acting perpendicular to the facade wall. Only in the horizontal direction is no positive connection available.

Advantageously, the fastening system comprises a third support profile, which is a combination of the first and second support profile. This makes it possible to use the same profile for the attachment of two superimposed facade elements.

Conveniently, at least four anchors are used to attach a facade element to the support profiles. Thus, the facade elements are each securely held on the support structure.

According to a particularly preferred embodiment, a first and second guide profile are provided, wherein the first guide profile is designed for vertical arrangement on the back of the facade element and a second guide profile for horizontal arrangement on the back of the facade element. Thus, the customer / installer has the opportunity to get the individual components / system parts pre-assembled or to assemble everything yourself in the construction, where he does not need any special tools. Depending on the format of the facade elements, one or the other guide profile can be used. If, for example, low but very wide façade elements have to be mounted, then the guide profile to be arranged horizontally is better suited than the other.

Advantageously, the slide along a guide longitudinally displaceable in the second support profile is receivable. This makes it possible to position the Schiebling already on the support profile, so that for the production of the molded connection of the sliding slide only has to be moved.

Conveniently, the Schiebling by means of a screw, preferably Allen screw, detectable on the second support profile. The screw is also easily accessible through the existing between two superimposed facade elements, small gap of 6 to 10 mm.

Advantageously, the anchor has a U-shaped or hook-shaped foot. This can form a positive connection with a rail or projection of the support profile, so that the element is secured against falling and wind suction.

According to a particularly advantageous embodiment of the U- or hook-shaped foot has a stop surface to determine the facade element with the support profile as an abutment in a particular pivot position. This has advantages in assembly and for service purposes. Thus, the facade element can be pivoted forward, for example, for service purposes in a tilted position in which the space behind the facade elements for fitters is accessible from the outside. This can be used to maintain or repair existing installations behind the façade elements (electrical lines, inverters, etc.).

Advantageously, the same anchor can be used both in conjunction with the first guide profile and in conjunction with the second guide profile. As a result, fewer parts must be kept in stock.

Preferably, the armature is held positively against the guide profiles on two opposite side. This ensures a good support of the anchor.

Advantageously, arranged on the guide profile anchors are oriented with their feet outwards. By the opposite arrangement of the anchors, which are arranged at the bottom of the facade element, and those which are arranged at the upper edge of the facade element, the anchor hooks are each in the region of the edge of the facade elements, which is an advantage during assembly and for accessibility is. Accordingly, the anchors are oriented on a vertically arranged guide profile in each case in opposite directions. At the horizontally arranged guide profiles, however, the anchors are each oriented in the same direction.

Advantageously, the guide profile has a clamping groove, in which a part of a fastening means is preferably received against rotation. Thus, the clamping groove itself is the counter bearing for the fastening means, wherein the one part of the fastening means may be a screw or a clamping shoe.

According to an advantageous embodiment, the support profiles each have two channels, in which for the purpose of connecting two adjacent support profiles a Stossprofil is inserted. Thus, the problem of thermal expansion of the profiles can be got under control.

Preferably, the Stossprofile are held in a form-fitting manner in guide grooves. As a result, the support profiles interconnected via the shock profiles can not be twisted against each other. Also, the bumps of the support profiles can be at any point.

The present invention is also a method for producing a building facade formed from individual facade elements, in which the facade elements are attached to support profiles, which in turn are arranged on a substructure of a building floor. This inventive method is characterized in that at the back of the facade elements guide profiles are fixed with anchors that are attached to the building wall at a distance from each other supporting profiles substantially horizontally, that the facade elements are mounted by means of anchors to a lower support profile and a first Form-fit connection is made, and that the facade element is then realized at an upper support profile by means of a arranged in Tragprofillängsrichtung on the support rail sliding a second positive connection. This manufacturing method is particularly advantageous because the facade elements can also be easily mounted by a person.

Advantageously, the facade element is pivoted during assembly after hanging on a lower support section against the upper support section, then brought the shift with the armature into engagement and found on the support profile.

Embodiments of the invention will now be described in detail with reference to the following figures. It shows:

1 to 11 show the structure and the individual components of a curtain wall structure 11, for example, with two superposed facade elements 13a and 13b. The facade elements, hereinafter referred to collectively by the reference numeral 13, according to the embodiment shown, glass plates 15 which are releasably secured by means of a guide profile 17 and anchors 19 disposed thereon horizontal support profiles 21,23, 25. The glass plates 15 may of course also comprise photovoltaic modules (not shown) applied to glass plates. However, this is a secondary aspect in the context of the present invention, since the subject of the invention has a system for fixing facade elements, in particular of photovoltaic modules and glass plates, the object.

As is apparent from Fig. 1, the support profiles 21,23,25 are fastened by means of rivets or screws 27 to a substructure of a building facade, not shown. The anchors 19 in turn are fastened with screws or rivets 29 to the guide profile 17. Incidentally, the connection of the facade elements by means of form-locking connections of the armature 19 with the support profiles 21,23, 25, as will be explained below.

The lower support section 21 has two channels 31,33, which are formed by a long base wall 35 and from this at a right angle protruding and mutually parallel webs 37, 39, 41. On the webs 37, 39, 41 each protruding ribs 43, 45, 47 are formed at the same height at a right angle, which extend parallel to the base wall 35. Between the ribs 43, 45, 47 are correspondingly in the direction of the webs 37, 39, 41 extending and indicated by arrows column 49, 51 available. This makes it possible to fasten the base wall 35 to a substructure of a building facade by screwing the screws 27 (FIG. 1) in the region of the gaps 47, 49 through the base wall 35 into the substructure.

In the channel 31 guide grooves 51, 53 are provided, which by projections 55, 57 in conjunction with the rib 43, respectively. the web 39 are formed. Likewise, two guide grooves 59, 61 are provided in the channel 33, which by projections 63, 65 in conjunction with the web 39, respectively. the rib 47 are formed. The Führungsnutenpaare 51, 53 and 59, 61 are used for the positive reception of a Stossprofils described below, which serves to connect two separate by a dilation gap support profiles 21. The Führungsnutenpaare 51, 53 and 59, 61 are formed so that they can each receive the same Stossprofil.

Formed on the support profile is an L-shaped nose 67, which is designed as an extension of the web 37 and projects beyond the lying in the same plane webs 43, 45, 47 ribs. The leg 69 of the nose 67 extends parallel to the base wall and towards the center of the support profile 21. In the finished facade construction, the leg 69 carries the whole weight of a facade element 13, which is supported on the leg 69.

At the side remote from the base wall 35 side of the rib 43, a guide groove 68 is provided with an undercut 70. This serves to receive a rubber profile, not shown in detail, on which the facade element rests in the mounted state. The rubber profile prevented a possible noise in wind and lateral slippage of the adjacent facade element.

The upper support section 23 and the middle support section 25 will now be described below. Since these support profiles 23, 25 partially have the same functionalities as the support profile 21, the same reference numerals are used for functionally identical parts.

Like the support profile 21, the support profiles 23, 25 each have two channels 31,33 with guide grooves 51, 53, 59, 61, which serve to receive Stossprofilen, with which two axially spaced apart support profiles are interconnected can.

The support section 23 differs from the support section 21 essentially in that, instead of a rail 69 for supporting a lower armature, a guide device formed by two mutually oriented guide grooves 71, 73 is provided. This serves to receive a sliding member, as will be described in detail below (FIG. 5). In addition, the support section 23 has yet another web 75 at a distance from the web 37. At these a cable clamp can be infected (see below description of Fig. 11).

The middle support profile 25 (FIG. 4) is a combination of the two support profiles 21 and 23 described above, the upper support profile 23 in the lower portion and the lower support profile 21 in the upper portion of the support profile 25 are reproduced. Accordingly, the same reference numerals have been used for the functionally identical elements as in the description of the support profiles 21,23. Accordingly, reference may be made to the above description of the support profiles 21,23.

The shift 77 shown in FIG. 5 comprises a substantially rectangular base plate 79 whose height is matched to the spacing of the guide grooves 71, 73 (FIG. 3). The shift 77 has a peripheral and upwardly open, U-shaped guide channel 81 which can cooperate with the armature to form a positive connection. In the walls 83a, 83b of the guide channel 81, a bore 85 is provided, which serves to receive a screw (not shown). With the help of this screw, the shift 77 can be fixed to a once taken along the support profile position, so that lateral slippage is impossible. In addition, the shift 77 still has a base plate 79 spaced and parallel stop plate 87 which is connected via a web 89 with the base plate 79. On the side facing away from the base plate 79 of the stop plate 87 is an elastic pad 91, e.g. a foamed plastic, arranged. At this pad 91, the facade element 13 is in the finished assembled state.

Figs. 6 and 7 show two embodiments of the armature 19 in more detail. The armature 19 comprises a rectangular base plate 93, in which on one side and at a distance from the nearer end side 95 a channel 97 having an undercut 99 is provided. The inside width of the channel opening 101 is greater by 0.5 to 2 mm than the thickness of the leg 69.

For a facade element to be mounted or dismounted, even if a facade element is already mounted above it, on the one hand on the outer channel wall 103, a bevel 105 and the edge 107 a bevel 109 is provided. This allows a facade element to be easily hooked onto the leg 69 of the rail 67, and it is e.g. to be left in a stable tilted position during assembly, repairs or servicing (see position 4 of Fig. 14).

To mount the armature 19 on the guide profile 17 (FIGS. 1 and 8), three bores 111 are provided which serve to receive the screws 29 or rivets (FIG. The armature 19 according to FIG. 7 has a further bore 115 in the channel base 113. This serves to receive an adjusting screw (not shown) with the aid of which the facade element can be aligned horizontally during assembly. The concept provides that the weight of the facade elements is removed via the adjusting screw on the rail 67.

Fig. 8 shows the guide profile 17 in more detail. This is formed as an extruded aluminum tube profile with a cavity 117 which also allows the insertion of a rivet for fastening the armature 19. The guide profile is preferably glued to the back of the facade element.

In Fig. 9, a support bracket 119 is shown, which can be mounted on demand or appropriate legal requirements on the guide profile to prevent falling of facade elements in case of fire. In this case, the leg 121 of the support bracket 119 is inserted into the cavity 117 of the guide profile 17 and positioned so that the second leg 123 rests against the front side of the facade element, and then screwed or riveted to the bottom 125 (FIG. However, it is also conceivable first to attach the support bracket to the guide profile and only then to glue the guide profile on the facade element.

Fig. 10 shows a formed as an angle profile Stossprofil 127 which fits positively and with little play in the guide grooves formed by the pairs of grooves 51,53 and 59, 61 guide. Due to the positive reception of the impact profile 127 in the channels 31, 33 of the support profiles 21, 23, 25, the support profiles can be lengthened without twisting. Because building facades can become very hot, the supporting profiles should not be longer than approx. 3m due to the length changes associated with them. The Stossprofil 127 has approximately in the middle of a downwardly bent nose 129, which prevents slippage of the Stossprofils.

The cable clamp 131 shown in Fig. 11 made of a spring steel or plastic can be, for example, to the rib 47 of the support sections 21,25 or the free web 75 of the support sections 23, 25 infected by the clasp 133 on the rib 47 or the Bridge 75 is clamped.

Fig. 12 shows the roof edge of a flat roof and the structure of the facade construction with the inventive fastening system. Reference numeral 135 denotes a building wall and numeral 137 an insulating layer attached thereto. Screwed to the building wall is a spacer 139, on which a vertical mounting rail 141 is arranged. At this turn, the support section 23 is arranged horizontally. It can be seen that the shift 77 can be fixed with a screwdriver 145, even if the roof closure 143 projects beyond the facade.

In Figs. 13 and 14, the individual steps of the production of a building facade are shown. First, the spacers 139 are screwed to the building wall (not shown) and then the insulation (not shown) attached. Thereafter, vertical mounting rails 141 are mounted to the spacers 139. Thereafter, the support profiles 21, 25 are mounted at predetermined intervals on the mounting rails 141 (step 2). The facade elements 13 with the guide profiles 17 are prepared at the factory and hung on the construction site on the lower support section 21 (step 4 in Fig. 14). Thereafter, the facade element is pivoted to the support section 25 and made the positive connection between the shift 77 and the armature 19 by the former moved along the support profile 25 and brought into engagement with the armature 19. Thereafter, the shift 77 is still fixed to the support section by a locking screw is screwed into the bore 85.

FIGS. 15 to 17 show an alternative embodiment of a guide profile 147 and an anchor 149 which fits thereto. The essential difference from the first embodiment of the invention described above is that the guide profile 147 has a longitudinally extending clamping groove 151 in which the anchor 149 can be fastened. This embodiment has the advantage that the anchor 149 does not necessarily have to be preassembled in the factory, but mounted on the site or can still be moved.

Since the anchor 149 has the same and even more functionalities such as the armature 17, the same reference numerals have been used for the description of the same effect features as the armature 17. Like the armature 17, the armature 147 has a base plate 93, a on the front side of the base plate 93 formed channel 97, outside of the channel wall 103 a bevel 105 and at a distance from the end face of the base plate 93 has a bevel 109. In conjunction with the undercut 99 of the channel 93 may be with the guide profile 147 and the armature 149th equipped facade element 13 are mounted at an angle to the plane of the facade wall to a lower support section 21. In addition, allow the same aforementioned technical features pivoting of the facade element, wherein the bevel 109 and optionally the bevel 105 in the one extreme position serves as a stop surface (s).

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

In contrast to the armature 17, the base plate 93 of the armature 147 after the chamfer 109 still a paragraph 153 and an adjoining, tapered guide portion 155. This can with a guide groove of the horizontal guide profile described below interaction (see description to FIG. 20 below). In the base plate two round holes 155a and 155b are provided, which serve to receive a carriage bolt 157 (FIG. 15). Depending on the guide profile used, the carriage bolt 157 must be inserted either in the central round hole 155a (vertical guide profile 147, see Fig. 15) or in the round hole 155b (horizontal guide profile, see Fig. 20 below).

In Fig. 17 is a finished with guide profile 147 and anchor 149 equipped facade element and the mounting of the armature 149 on the back 159 of a facade element 13 is shown in an exploded view. It can be seen that the guide profile 147 is set back by a certain distance from the upper and lower end faces 161, 163 of the facade element 13. In this case, the armature 147 is mounted on the guide profile 147, that the guide portion 154 projects beyond the guide profile 147 frontally. In order to secure the anchor 149 in addition, this is secured by a preferably self-drilling screw 165 which is screwed through the free round hole 155 a.

The attachment of the guide profiles is advantageously carried out by gluing. The guide profiles are first glued two self-adhesive strips 167 at a distance from the side edge 169 of the base wall 35 of the guide profile and the latter then on the back of the facade element. Thereafter, the remaining cavities between the adhesive profiles 167 and the side edges 169 with an appropriate high-performance adhesive, an adhesive joint 171 created.

In conjunction with the guide profile 147, a support bracket 173 may be used, which connects to the connecting webs 175, the side walls 177 of the clamping groove 151 with the intermediate walls 179, which are provided for manufacturing considerations, connects (Fig. 15). The mounting bracket has a first leg 123 which rests in the mounted state on the facade element, and two second legs 125 which fit into the space between the side wall 177 and the intermediate wall. The attachment of the second leg 125 is preferably carried out by means of rivets 181st

The reference numeral 183, a third embodiment of a guide profile is shown in Figs. 20 and 21, which is suitable for horizontal mounting on the back of a rectangular facade element low height and large width. By low height is meant a height of less than about Im or preferably less than 80 cm, wherein the width is equal to or greater than or a multiple, in particular more than twice or three times the height. For fixing such facade elements two or more vertical guide profiles would have to be used, which would mean an increased production cost. In a horizontal arrangement of the guide profiles, however, two sufficient.

The guide profile 183 is mirror-symmetrical with respect to a central web 185. It has two clamping grooves 187, can be inserted into the carriage bolts 157 for attachment of an armature 147. A rotation of the screw 157 is prevented by the square in the clamping groove 187 positively received square 189 of the carriage bolt 157 (analogous to the guide profile 147). In the upper third of the side walls 191 of the clamping grooves 187 is a web 193 with an oriented to the profile center U-shaped guide groove 195. When mounting the armature 147 this is first inserted with the guide portion 154 in the groove 195 and then pivoted against the front of the guide profile 183 , In this case, the carriage bolt 157 must first be brought into the correct position so that the screw shaft 197 can be inserted into the laterally arranged round hole 155b and then screwed tight with a screw nut 199. As can be seen from FIG. 20, the cavity beneath the web 193 serves to attach the adhesive profile 167 and the adhesive joint 171.

In Fig. 21 the assembly of the armature 147 is shown in exploded view. The guide profile 183 has the advantage that it can never be installed incorrectly due to the symmetry. In the horizontal arrangement, the long side wall of the guide profile is flush with the upper or lower side edge 161, respectively. 163 of the facade element, but may also little, i. by max. 2 mm, opposite the upper or lower side edge 161 resp. Be set back 163 of the facade element.

The last-described alternative embodiment of the fastening system has the advantage that one and the same anchor 149 can be used both in the vertical guide profile 147 and the horizontal guide profile 183. In addition, the anchor 149 can be set only on the site.

Finally, Fig. 21 shows a third embodiment of an armature 201, which can be used in conjunction with the guide profiles 147, 183, when, in the case of a highly cantilevered component, e.g. a Dachrandabschluss or a windowsill, the accessibility to the shift is no longer possible. In this case, the facade element is merely suspended from a support profile 203 of a fourth embodiment (FIG. 22). The fourth embodiment of a support profile 203 has a base wall 35, on which on one side to the base wall 35 perpendicular side wall 205 is formed with an oriented to the profile center crosspiece 207 with a nose 208, and on the other side a remote from the base wall heel 209, which can be engaged behind by an anchor hook. At paragraph 209, a web 211 is formed with a nose 213.

Starting from a base plate 215, the armature 201 has two projecting hooks 217 and 219, the upper, first hook 217 engaging behind the shoulder 209 and the lower second hook 219 resting against the nose 208. A curved arcuate portion 221 narrows the opening of the first hook 217, so that the web 211 is received with the nose 213 with little play. Of course, the support profile 203 and the armature 201 are compatible with the remaining components of the fastening system, i. in the same depth applies as the other combinations of support profiles 147, 183 and Ankerl9. The mounting and support profiles of the inventive fastening system are preferably extruded profiles and advantageously aluminum extruded profiles, as well as the various embodiments of the anchor, which can be cut to length from a longer profile.
