Description

The invention relates to a bracket on facade panels, the several retaining bolts projecting on the wall have plate-parallel retaining collars by at least one hook-like wall anchors are engaged with an anchor bolt can be anchored in the wall and the retaining bolts in suspension slots takes up, with a releasable assembly tool is available.

A bracket on facade panels, several on the wall projecting retaining bolts with retaining collars parallel to the plates, which engage behind at least one hook-like wall anchor are anchored in the wall with an anchor bolt, is known from DE-A-3 737 081. The well-known retaining bolt is axially positively connected to the facade panel and supports a threaded nut on the wall that holds the plate-parallel retaining collar forms. This collar or the well-known mother becomes gripped by a wall anchor, the frame construction is formed, which with fastening screws in the wall is anchored. This connection of the wall anchor to the wall and also the connection of the wall anchor to the facade panels or whose retaining bolt is due to the necessary individual Adaptation and also cumbersome due to the large number of parts to handle. Problems also arise in particular in the positioning and in the production of connection points on the wall on the one hand and on the facade side of the other on the part of

DE-A-1 916 590 discloses lightweight concrete slabs and Screw the retaining strips together using retaining bolts and the retaining strips to be provided with wall anchors in the existing ones in the wall large pear-shaped, undercut anchor holes inserted in which mortar is then poured in around the lightweight concrete slabs to fix. The wall anchors are bolts with nuts to be attached to the retaining bar, which via spacers screwed to the back of the lightweight concrete slabs. The bracket is accordingly constructed in many parts and complex to manufacture. The positioning of the lightweight concrete slabs is not uncritical as you have to wait until the mortar is cured. The assembly effort with the known bracket is accordingly high.

From FR-A-2 540 160 is a bracket with the entry known features known. The facade panel is large in size and correspondingly heavy, so it will be with a hoist raised to a position in the lower retaining bolt of the facade panel positioned in slots of anchor bolts are. Around the top edge of the facade panel for fixing it Securing to the wall is a wall-side metal bracket used, the tilting of the facade panel from the wall as long prevents up to the upper retaining bolts in the facade panel are screwed in and hold them against tipping. Then it will be the metal clip is removed. The well-known metal clip is in essentially an assembly safety device. On your application can be dispensed with if that takes place in the usual way mechanical connection between wall anchor and retaining bolt is done quickly enough. As a result, it complicates known metal bracket the attachment of the facade panels.

In contrast, the invention is based on the object To improve the bracket with the features mentioned above, that the facade panels with simple means and in simple Way can be attached to the wall.

This object is achieved in that as a releasable assembly aid a spring element between the retaining bolt and the wall anchor is present, the wall anchor against the retaining bolt pulls and is fixed on a plate edge.

Of importance for the invention is that of a screw connection the facade panels with a substructure, namely is moved away with the wall anchors. Rather, they are hook-like Wall anchors available, into which the retaining bolts with their plate-parallel retaining collars are attached. Accordingly the assembly of the facade panel with the wall anchors is extremely simple. A screw connection is not necessary. Accordingly the assembly effort is drastically reduced. The for the permanent connection of the facade panels with the wall anchors required holes in the facade panels and as retaining bolts Items to be used can be manufactured in the factory and can also be used on site in a simple manner.

Of particular importance for the assembly of the facade panel with the wall over the wall anchors it is that the wall anchors and the retaining bolts always have the same relative position to one another. Only then is it guaranteed that the anchor bolts of all wall anchors can be used correctly in the wall holes, which according to the scheme of the distribution of the retaining bolts over the facade panel were manufactured. So in order to achieve that Anchor bolts of the wall anchors have the same distribution pattern, like the retaining bolts, the bracket is designed so that before the plate assembly a permanent cohesion between the retaining bolts given a plate and its associated wall anchors is. The detachable connection of both components makes it possible to the insertion of the anchor bolts into the wall or after fastening the anchor bolt in the wall, e.g. with an adhesive anchor, remove the plate again to check whether the anchor bolts sit sufficiently deep in the wall and in the adhesive. Subsequently the facade panels can be easily attached to the retaining collar their retaining bolts hooked back into their wall anchors be, the wall hole filled with adhesive the anchor bolt through unsolvable Adhesion holds so that a change in the desired Position of the facade panel relative to the wall is not he follows.

The bracket is in view of the detachable connection the retaining bolt with its wall anchors designed so that for the detachable connection between the retaining bolt and the wall anchor a spring element is present that against the wall anchor pulls the retaining bolt and fixes it to a plate edge is. The spring element clamps the retaining bolt with the wall anchor, so that both together with the facade panel form a structural unit. On the other hand, the spring element because of its detachable attachment to the plate edge can be easily removed so that a solution of the connection between the retaining bolt and the wall anchor, for example after the wall anchor is fixed in place is. The repeal of the setting of the spring element on the Panel edge makes this assembly tool easy from the space between the facade panel and the wall remove what there is enough space for, e.g. because of that in this Thermal insulation still to be installed, for example after after removing the facade panels and after check that the anchor bolts are properly seated in the wall has been.

To a simplified detachable connection with the spring element between the retaining bolt and the wall anchor, the bracket is designed so that the spring element with a rigid hook the wall anchor and with another dimensionally stable hook engages behind a plate edge. The rigid Hooks allow a secure attack on the wall anchor or at the edge of the plate with simultaneous freedom in the Design of the spring element between these two hooks. A secure fit is guaranteed.

The holder is advantageously designed such that that the hook engaging behind the wall anchor has a plate flanged lower edge for a plate-shaped anchor hook with a slanted bottom edge. With such a configuration can the hook behind the wall anchor without further consist of a sheet, the manufacture of which with simple Funding is done and also for a variety of applications of the assembly aid is sufficiently durable is.

For analog reasons, the holder can also be designed in this way be that the hook engaging behind the plate edge a sheet metal plate with the sheet edge encompassing the plate edge is. The hooks described above must on the one hand on the designs consider the retaining bolt and the wall anchor, on the other hand also that on the back of the Facade plate a variety of brackets or retaining bolts and wall anchors are present. In view of this, the Bracket designed so that the behind the wall anchor Hook a slot open in the area of a hook edge for embracing the anchor bolt and the game Has retaining collar and / or that the behind the plate edge Hook a recess to enclose a plate edge near Bracket. The open slot can be used during manufacture the hook is punched out by punching be, whereby the game is dimensioned so that the hook without long trials can be put. When designing the hook behind the plate edge can take this into account be taken that two retaining bolts are aligned and that Assembly aids of a retaining bolt in or over the area the other retaining bolt would have to be relocated. The one with it associated difficulties are exacerbated by the the hook behind the plate edge avoided.

It is necessary to design the bracket so that the hooks engaging behind the wall anchor or the plate edge Have fasteners for the spring element, so a variety of separate parts for each other a single securing point or a single retaining bolt is avoided.

It is particularly advantageous if the holder is designed in this way is that the spring element is a perforated rubber band that with its holes over at least one each as a locking projection trained fastener one of the rear engaging Hook is buttoned. The rubber perforated tape can with the Snap projections of the hooks can be easily assembled. This assembly is reliable and cannot be solved accidentally. On the other hand, the perforated rubber band can easily be used again unbuttoned, for example if it is very worn or torn out at one end, or when another Length should be set, if with the same assembly tool a facade panel of a different size can be installed should.

To make the bracket as flat as possible, it is designed so that the retaining bolt one in the plate arranged dowels with a radially projecting ring collar and a dowel retaining screw with a radial ring collar outstanding head that forms the plate-parallel collar and that the ring collar of the dowel in a hanging slot a plate-parallel anchor hook is attached. As a result, the retaining bolt is a two-part component, whose dowel holding screws perform two functions, namely on the one hand, securing the position of the dowel in the facade panel in the intended spread position and on the other the secure connection to the wall anchor by the plate parallel Retaining collar is designed so that it from the anchor hook of the wall anchor can be accessed. Between the retaining collar of the retaining bolt and the facade panel only needs a comparatively narrow, due to the thickness of the Ring collar of the anchor to certain distance or space into which the anchor hook can be inserted that its suspension slot encompasses the ring collar of the dowel. Since the plate of the assembly aid that engages behind the wall anchor is also flat, like that e.g. as a rubber tape trained spring element, no part of the bracket jumps in the direction of the anchor bolt far forward, so that the space between the back of the facade panel and the Wall can be narrow or in the remaining distance between enough space for the assembly tool and the wall Is available to remove the need if necessary Carry out the necessary manipulations to be able to.

The holder can advantageously be developed in this way be that the anchor bolt near its wall end one covering the associated wall hole on the bolt when it is pushed into the bore elastic cover plate is provided. The elastic cover plate leaves out excess adhesive a wall hole, but prevents it from flowing out unintentionally.

A further development of the bracket is that the Anchor bolt with one after applying a thermal barrier coating pluggable between the wall and the facade panel Insulation layer holding disc is provided. Consequently it is possible to count the number of others outside the range the anchor bolts to be used to hold the thermal insulation layer at least to decrease.

The bracket can also be perfected be that attached to the wall over the top plate edge Facade panel at least one on the facade side projecting mounting aid rail is releasably hooked, the Retaining hook after attaching another facade panel from the joint between the two facade panels after twisting can be pulled out by 90 °. The auxiliary mounting rail allows it, a facade panel assembled with wall anchors guided on the lower edge with the anchor bolts leading to the Push the wall closed, the anchor bolts of the wall anchors being correct engage in the holes in the wall and load the Facade panel over their retaining bolts due to tilting of the Facade panel is minimized. Accordingly, the the mounting bolts holding the mounting bolts and the wall anchors together relieved. Because the retaining hook on the joint width can be adjusted, it is possible to use the auxiliary mounting rail easy to remove.

Another specialization of the bracket is given if the retaining hook with the mounting aid rail crosswise to Plate connected in an adjustable manner and in its screw-in positions can be fixed with a locking screw. A Bracket or an auxiliary mounting rail with such Holding hook makes it possible to also use the mounting aid rail for different Use plate thicknesses.

In particular, the holder can be designed that the mounting aid rail is removable after next to it support in the joint between the two facade panels are introduced. The early removal of an assembly aid rail allows you to use it elsewhere, when fixing the anchor bolt in a hole in the Wall is not yet immovable. Secure during this time the support means the position of the facade panel sufficiently.

The holder is advantageously designed such that that the wall anchor has an anchor bolt parallel to the retaining bolt, the plate-side end of a plate-parallel anchor hook Has. The anchor bolt is designed so that the wall anchor can be conveniently anchored in the wall. The design of the anchor bolt can be left to the respective application stay. However, this is the end of the anchor bolt on the plate side provided with a plate-parallel anchor hook that the hanging of the facade panels or the retaining bolts Facade panels made easier.

The holder is advantageously designed so that the plate-parallel anchor hook from a flat plate consists of an anchor bolt designed as a threaded bolt is welded. The level forming the anchor hook Plate can be easily made by punching and their welding to the anchor bolt is easy mechanically possible. Because the anchor bolt as a threaded bolt is formed, it can easily in a wall Dowels are used, but preferably as adhesive anchors, by filling the threaded bolt with a wall hole filled with adhesive takes up, with an inseparable bond of the threaded bolt takes place with the wall.

The bracket is advantageously designed so that the plate-parallel anchor hook has a vertical, open top Has a slot that is longer than that Joint width between two facade panels. For permanent A simple slit is sufficient to hold the facade panels in the wall anchor. The hanging length is dimensioned so large that a facade panel located in a composite panel not unintentionally from the associated suspension slots of the wall anchors can be removed, namely larger than the joint width between two facade panels. On the other hand, it is not difficult possible to replace a facade panel by using the other facade panels located so far be raised that the suspension slot for the retaining bolts become accessible to the facade panel to be renewed.

If the plate-parallel anchor hook several each other has parallel suspension slots for one retaining bolt each it is possible to use a facade panel with fewer wall anchors Attach to wall. In the case of an anti-twist in the wall A single such wall anchor is sufficient, the one with its mutually parallel suspension slots a corresponding Number of retaining bolts and the facade panel with it supported in several places.

The position of the plate anchor of the wall anchor on the retaining bolt or relative to the facade panel determined by the fact that the dowel holding screw between their Head and the thread one in the installation position directly or has a spacer collar that supports the dowel via an annular collar, whose height is slightly larger than the plate thickness of the anchor hook is. As a result of the minor due to the spacing covenant the dowel retaining screw with its axial play Spacer collar lightly in the hook slot of the anchor hook be hung up. The spacer collar ensures that the head the anchor screw always for the thickness of the anchor hook maintains the required distance from the dowel.

So that the wall anchor with a dowel parallel anchor bolt always has the desired exact axis-parallel position, the Bracket designed so that the anchor hook on the plate side Spacer projections is provided, whose projection is approximately the same the thickness of the ring collar of the anchor and / or the anchor screw is.

The bracket can advantageously be designed such that a U-shaped resilient bracket is available for Holding a wall anchor together with a facade panel fastening the facade panel to the wall with a Leg over the retaining bolt and with the other leg below the wall anchor is clamped. The two legs of the bracket apply the retaining bolt and the wall anchors to each other to, whereby the arrangement of the dowel holding screw in Slot base of the suspension slot is guaranteed and thus as close as possible to the anchor bolt.

So that the retaining clip of the bracket is as immovable as possible is, the latter is designed so that the retaining clip the mutually facing leg edges locking recesses and / or has an insertion stop.

Another option, the retaining bolt and the wall anchor as immovable as possible in a predetermined relative position To connect with each other is to design the bracket so that to hold together a wall anchor with a facade panel before fastening the facade panel to the wall a clamping part is pushed onto the head of the dowel holding screw and / or is attached, which latches the anchor bolt. The fastening of the clamping part on the dowel holding screw can meet the requirements for connection strength be designed accordingly, for example as a clamp seat, while the locking takes place exclusively on the anchor bolt. It is also a very material-saving design.

It can be advantageous if the retaining clip or the Clamping part with a plate-length handle and / or with spacing projections is provided. With the plate-length handle the bracket can be removed once the wall anchor is sufficiently firmly connected to the wall. That is with one Glue the case when the adhesive has hardened sufficiently. By removing the retaining clips, they can be used again be and so it is not necessary for everyone Connection point of a facade panel each a clamp to use. The spacing projections serve an improved Alignment of the retaining clip or the clamping part between the facade panel and the wall parallel to both.

If the wall anchor is assembled with the retaining bolt should be free of play, the bracket is designed so that the anchor hook and / or the retaining collar is a conical or the like. Clamping spring bridging with the hanging game turned off across the facade panel.

A facade panel shown partly in section in FIG 11 is intended with a wall 14 shown in FIG several places. For example three connection points distributed over the facade panel 11, namely two near the bottom longitudinal edge nearby the side edges and one above for explanatory purposes only a lower connection point near the upper longitudinal edge 11. According to this distribution of the connection points three holes must be drilled in the wall Placement taking into account the used Bracket 10 has to be done.

Each bracket 10 consists essentially of one of the Facade panel 11 associated retaining bolt 12 and one essentially the wall anchor 15 assigned to the wall 14. Around the retaining bolt 12 to be able to connect to the facade panel 11 the latter per attachment point with one not through the facade panel 11 continuous undercut borehole 20 provided so that the visible side of the facade panel 11 through the attachment points and in particular through the retaining bolt 12 remains optically unaffected. In the borehole 20 is a Dowel 21 used, which is substantially sleeve-shaped and has a coaxial threaded bore 23. Its bore side The end is slit lengthways so that appropriate spreading tabs arise, the radial at their bottom ends Protrusions 22 'carry which in the undercut, not designated of the hole 20 can intervene, since they are the corresponding Have shape. When inserting the dowel 21 in the borehole 20, the spreading lobes are initially so widely compressed that they insert the plug 21 in do not obstruct borehole 20. After that, the spreading lobes pushed apart by a dowel retaining screw 24 in the threaded bore 23 is screwed in until the spreading tabs of the dowel 21 assume the position shown in FIG. 1, in which its projections 22 'undercut the bore 20 to complete. In this position, the spreading flaps are removed the dowel holding screw 24 held so that it can be pulled out of the plug 21 impossible within the predetermined pull-out forces is. The dowel holding screw 24 has a screw head 24 ', the outer circumference of which is circular and concentric with the Screw axis an internal hexagon recess 24 "for screw actuation having. To the exact positioning of the dowel 21 to facilitate this is with a ring collar 25 Mistake. The ring collar 25 is expediently as a hexagon trained to the dowel when screwing in the dowel holding screw 24 to be able to hold on. A corresponding ring collar 25 has the dowel holding screw 24 of FIG. 9a. Of the However, ring collar 25 of this screw does not need to be a hexagon to be trained. This ring collar 25 can to the Kick the ring collar 25 of the dowel 21. Both ring collars have the thickness 29, which is the distance between the wall anchor 15 determined by the wall-side surface of the facade panel 11.

The dowel holding screws 24 of FIGS. 9.9a have one Screw head 24 ', the outer circumference of which is circular, and the A hexagon socket recess concentric with the screw axis 24 "for screw actuation. On the screw head 24 'closes a spacer collar up to the screw thread 26 37, which in both cases ensures that between the head 24 'and the ring collar 25 one for receiving a Part of the wall anchor 15 required clear width guaranteed becomes. The outer diameter of the ring collar 25 and Screw head 24 "of the dowel holding screw 24 of FIG. 9a same size.

For engagement between the screw head 24 "and the wall side Plate back 11 "comes a plate-parallel anchor hook 17 of the wall anchor 15. This wall anchor 15 consists in essentially from this plate-parallel anchor hook 17 and an anchor bolt 16. The anchor hook 17 is a flat plate with a suspension slot 18, the width of the diameter the ring collar 25 or the spacer collar 37 is coordinated. The anchor bolt 16 is on the plate-parallel anchor hook 17 attached at right angles, for example by welding. While the plate-side end 16 ′ of the anchor bolt 16 the connection with the anchor hook 17 is the other End 16 "of the anchor bolt 16 in a bore 40 in the wall 14 used and fixed there for example by gluing, see Fig. 3. For this purpose, the anchor bolt 16 is threaded provided, which the required pull-out strength of the anchor bolt 16 guaranteed from the wall 14. So that the anchor bolt 16 the position shown in FIGS. 1 and 7 exactly; can take, the plate of the anchor hook 17 of the facade plate 11 be parallel. In particular, the anchor hook 17 not around the vertical axis in the display plane be pivoted. This is ensured by spacing projections 28 8 at the same distance from the axis of the Anchor bolt are arranged and on the back of the plate can support. Accordingly, their lead is the same Thickness 29 of the ring collar 25 of the retaining bolt 12. If one 9a screw used together with a dowel, the has an annular collar 25, the double thickness 29 determines the Distance between the plate-parallel anchor hook 17 and the wall anchor 15 from the back of the plate 11. Larger accordingly must also be the protrusions of the spacer protrusions 28.

The strength of the anchor hook 17 is such that it with slight axial play between the head 24 'of the dowel holding screw 24 and the rear 11 "of the facade panel 11 engages, whereby the game is dimensioned so that an effortless Handling is possible, namely when assembling the wall anchor 15 with the retaining bolt 12, as with a disassembly of these two components after attaching the anchor bolt 15 in the wall 14. If this game is undesirable is, the anchor hook can be used with play-bridging clamping springs 38 are provided, which are shown in Fig. 13, 14. Fig. 13 shows a clamp spring 38 which on the fork projections of the anchor hook 17 can be plugged on, so that its conical Tip 38 'between the ring collar 25 and the holding collar 13 takes hold. If the provided with a clamping spring 38 according to Fig.13 Anchor hook 17 assembled with the retaining bolt 12, see above the conical clamping spring 38 slides on, bridging the play, as well as the clamping spring 38 of Fig. 14, which bead projections 38 "to bridge the game. A hanging game then no longer exists.

In Fig.1a the suspension slot 18 can be seen with the the plate-parallel anchor hook 17 designed as a hexagon Grips ring collar 25. The game of the hanging slot 18 is dimensioned so that the angular position or rotational position of the ring collar 25 in the plate 11 can be any. There is only one position line from the dowel holding screw 24 24 '' 'of the outer circumference of the screw head 24'.

2 shows a view of the rear side 11 " Facade panel 11 one panel edge 11 'and two over the facade panel distributed attachment points 42 at which one Top view of the screw head 24 with the hexagon socket 24 " is shown, as well as an anchor bolt 16. Furthermore Two assembly aids are shown, each from two hooks 45, 46 and a spring element connecting them 44 exist.

The hook 45 is in the area of a fastening point 42 a plate made of sheet metal with flanged according to Fig.1 Lower edge 47. This includes the lower edge 48 of the plate-shaped Anchor hook 17. The lower edge 48 is beveled so then securely grip the lower edge 47 of the hook 45 can if the anchor plate is close to the plate rear wall 11 " is present. A slot 50 is provided in the hook 45, which is in the area of the hook 45 game for embracing the anchor bolt 16 and of the holding collar 13 forms. As a result, the hook 45 1, the head 24 ′ functioning as a holding collar 13 Fastening screw 24, like the anchor bolt 16, whereby it does not bulge in its axial direction.

The hook 46 of the upper arranged on the plate edge 11 ' Fastening point 42 engages around the plate edge 11 'in similar to how the lower edge 47 of the hook 45 the lower edge 48 engages around the anchor hook 17. He lies with his essential area on the back 11 "of the facade panel 11 on.

Both hooks 45, 46 have fasteners 52 that act as mushroom-shaped locking projections are formed. They serve in Connection with the spring element designed as a rubber perforated band 44 the mechanical connection of all three components. The Rubber perforated tape is with a hole 43 over a locking projection buttoned and therefore cannot be unintentionally off the hook 45.46 to be removed. To secure the connection is on the hook 46 a slot 53 near the other hook 45 facing Edge provided through which the rubber perforated tape from the Plate back 11 "is pushed through. This serves the additional Fuse.

The hook 45 of the lower attachment point 42 is with provided two fastening elements 52 arranged one above the other, so that the hook 46 correspondingly by the spring element 44 is kept straight, what its handling in the area of this lower attachment point 42 facilitated.

Because of the two aligned mounting points 42 is the hook 46 for the lower fastening point 42 formed so large that it has a recess 51 with which he can use the entire assembly aid of the upper fastening point 42 engages so that it is just as flat on the back 11 "of the facade panel 11 rests, like the hook 46 of the Assembly aid for the upper fastening point 42. In both In some cases, the hooks 46 encompass the plate edge 11 ' Sheet edge 49 similar to the lower edge 47 of the hook 45.

The assembly tool described above is used in such a way that first the hook 46 is assembled with the wall anchor 15 is after this with the retaining bolt 12 on the Hook slot 18 and the retaining collar 13 was coupled. After that the perforated rubber band is tightened and the upper hook 45 with its sheet metal edge 49 inserted over the plate edge 11. The Elasticity of the rubber perforated tape pulls the two hooks 45, 46 towards each other, which thereby the cohesion between the Ensure the retaining bolt 12 and the wall anchor 15. Elasticity and hole spacing are coordinated so that on the one hand a secure fit and different on the other Plate dimensions can be mastered safely. It has been shown that with such an assembly tool an essential higher laying performance can be achieved than with the conventional brackets for facade panels.

In Figure 3 is a facade panel attached to the wall 14 below 11 shown. Of the z. B. three for attachment provided anchor bolt 16 is one near the top Plate edge 11 'shown. The attachment of the anchor bolt 16 in the associated bore 40 is done by gluing, what was used a common adhesive anchor, the adhesive 59 the space between the anchor bolt 16 and the wall the hole 40 fills. Because an exact dosage of the adhesive is not possible, e.g. B. because of different insertion depth the anchor bolt 16, the adhesive is here generously dimensioned and must pass through the penetrating anchor bolt 16 are pressed out of the bore 40. On the other hand, must to ensure that no voids are created. Consequently is the anchor bolt 16 with an elastic cover plate 53 provided on the end 16 "of the not yet inserted Anchor bolt 16 sits and when inserted is supported in the bore 40 on the wall 14. About exiting Adhesive can drain off because the cover plate is elastic is. On the other hand, the cover plate 53 can be sufficient be stiff to completely fill the bore 40 between to ensure the bore wall and the anchor bolt 16.

Between the facade panel 11 and the wall 14 is one Thermal barrier layer 54 is arranged on the wall and must be fastened there will. The usual fasteners can be used for this be used. Fig.3 shows that an additional, the number of the conventional fasteners used if necessary down to zero reducing possibility is on the anchor bolts 16 an insulating layer holding disc shown in Figure 4 55, which are provided with a slot 55 ' is. This disc 55 sits in the axial direction the formation of the anchor bolt 16 as a threaded bolt and can thus press the insulation layer 54 against the wall. The The thermal insulation layer 54 is arranged on the wall in such a way that slits are cut in the thermal barrier coating, so that this with removed facade panel 11 over the wall anchor 15 can be inserted. After that it is not a problem that To install insulating layer retaining washer 55.

So that another facade panel 58 above the facade panel 11 of Figure 3 arranged simply and quickly can be, auxiliary mounting rails 56 according to Fig.5 used. The facade panel 58 is in the area of its retaining bolts 12 completed with wall anchors 15, both through the tools shown in Figures 1,2 held together are. The auxiliary mounting rail 56 serves accordingly to guide the facade panel 58 on the lower edge 58 ', when the facade panel 58 with its anchor bolts 16 in the Bores 40 is inserted. There is a relief the installation of the facade panel 58 on the wall 14 through the alignment achieved with the auxiliary rail 56 with respect to FIG the upper panel edge of the lower facade panel 11. The assembly aid rail 56 consists of one from the visible side of the Facade panel 11 projecting angle, the two angle legs 60,61 connected by a reinforcing plate 62 are. The thickness of the angle leg 60 is expedient equal to the gap width between the two plates 11.58. Consequently is the facade panel 58 with the help of the mounting aid 56 in the one applicable to the facade panel 11 Position pushed, so that it with the facade panel 11 is aligned. Here is just the vertical alignment control in the display level if the Facade panel 11 with two horizontally arranged one behind the other Assembly auxiliary rails 56 is provided.

The auxiliary mounting rail 56 is provided with a holding hook 57 provided that the facade panel 11 with the hook leg 63rd engages behind. The holding hook 57 is dimensioned so that its horizontal or screwed into the auxiliary mounting rail 56 Hook leg 67 corresponding to the desired plate distance Has thickness and that the vertical angle leg 61 of Auxiliary mounting rail 56 close to the visible side of the facade panel 11 is present. As a result of this arrangement must be in use the auxiliary mounting rail 56 to the panel thickness of the facade panel 11 must be respected. Therefore, the holding hook 57 be a separate part from the auxiliary mounting rail 56. Both Parts are screwed together, for what the auxiliary mounting rail 56 has a bore 64 and the retaining hook 57 has a screw thread pin 65. The latter can be in the bore 64 of the given panel thickness of the facade panel 11 are screwed in correspondingly deep. So that position cannot be changed unintentionally, is not shown Locking screw in place in the mounting aid rail 56 is screwed in and transversely onto the retaining hook 57 presses.

The auxiliary mounting rail 56 must be removed, either happens after the anchor bolt 16 of the wall anchor 15th firmly in the wall 14, or by in the through the auxiliary rail 56 defined plate joint support means z. B. in shape are introduced by spacer blocks. This rail 56 is then 90 ° with respect to the representation level of FIG rotated so that the hook 57 is also pulled out with its leg 63 can be. The leg 53 is flattened accordingly.

In Fig. 10 is the outline of a plate-parallel anchor hook 17 shown in dashed lines. Likewise, the head 24 ' Dowel holding screw and the diameter of the anchor bolt 16 dashed shown. The retaining bolt 12 and the wall anchor 15 are resiliently compressed by a retaining clip 30 or clamped together by a U-shaped resilient Holding bracket 30 is provided, which has two legs 31,32. The leg 31 is above the head 24 of the dowel holding screw 24 arranged while the leg 32 the anchor bolt 16 engages. Due to the spring action of the bracket 30 are the retaining bolt 12 and the wall anchor 15 so squeezed as tightly as possible, with the reason of the Hook slot 18 is supported on the spacer collar 37. So that Position of the retaining clip 30 is ensured are in the edges the leg 31,32 locking recesses 33 are present, which to the Curvatures of the head 24 of the anchor bolt 16 are adapted. Further there is an insertion stop 34 against the head 24 bumps when the retaining clip 30 in the position shown is pushed.

The application of the holding clip 30 is such that a facade panel 11 according to Figure 12 with the visible side a mounting surface is laid. Then the dowels 21 inserted and screwed in the dowel holding screws 24. The Wall anchors 15 are then with their anchor bolts 16 in the Fig.7 brought clear position so that the retaining clips 30 can be pushed from right to left according to FIG. All connecting parts are now on the back the facade panel 11. After the holes 40 in the Wall 14 were made using the drilling template for the Bores 20 of the facade panel 11 also for the bores 40 the wall 14 was used and after in the holes 40th Glue was introduced, the facade panel 11 with the there holding clips 30 attached to the wall 14 are, the retaining clips 30 remain until the Adhesive is cured. Then the brackets 30 from the Screw heads 24 'and the anchor bolt 16 are withdrawn. For this serves a handle 35 provided on each holding clip 30, which protrudes laterally over the surface of the facade panel 11 and removing the clips 30 allowed. Each handle 35 consists 11 from a hollow profile, which is dimensioned in this way is that it is in the space between the facade panel 11 and the wall 14 fits. Around the bracket 30 in this Keeping the space vertically aligned is the retaining clip provided with spacing projections 36, for example from a threaded pin inserted through the clamp 30 lock nuts turned on both sides can exist. Out 10 to 12 it can be seen that the handles 35 on the Longitudinal edges of the retaining clips 30 are attached. Consequently can by turning the brackets 30 around in the display plane horizontal acnse that can be achieved also two horizontally aligned connection points with retaining clips 30 can be loaded without their handling 35 disturb.

15, 16 show a clamping part 39, which also the cohesion of the wall anchor 15 and the retaining bolt 12 before serve to attach the facade panel 11 to the wall 14. For this purpose, the clamping part 39 has an annular body 40 equipped, that on the head 24 'of the dowel holding screw 24 is pushed and / or fastened. An annular collar 41 of the dowel holding screw 24 keeps the clamping part 39 at a distance from the anchor hook 17 of the wall anchor 15. On the ring body 40 of the clamping part 39 are parallel projecting locking legs 42, the clasp the anchor bolt 16 into place. In this case, too So the anchor bolt 16 and thus the entire wall anchor 15 pulled as close as possible to the retaining bolt 12 and thus the relative position of the two connecting components 12, 15 all joints between the facade panel 11 and the wall 14 ensures.
