Description

facade

The present invention relates to a facade for the cladding of buildings, under a facade a plurality of to be fixed to a primary structure supporting structures for receiving point holders for facade elements made of insulating glass, a plurality of facade elements made of insulating glass and a plurality of point holders for fixing the facade elements made of insulating glass to the supporting structure.

Facade elements made of insulating glass consist of two or more panes of glass, which are separated by one or more spaces filled with air or with a noble gas. Usually, such a facade elements composed of two glass panes, which are glued to a spacer profile made of aluminum or stainless steel. The space created by the bonding with the spacer profile is filled with air or inert gas. For hermetic sealing of the insulating glass, the edge joint formed by the spacer profile and the two glass panes is sealed by means of a silicone sealant.

From DE 201 10 192 Ul a point holder for double-pane insulating glass with an outer glass pane and a spaced-apart inner glass pane is known. The point holder is anchored by means of a head of a threaded bolt forming expansion body in the form of an expansion cone and a spreader, which is pushed onto the spreader in a conical undercut having blind hole on one of the inner glass pane facing side of the outer glass. Starting from this anchorage, the point holder extends through a gap separating the two glass panes and through a through hole in the inner glass pane to the outside, so that the shaft of the point holder protrudes for the most part on the inner glass of the double-pane insulating glass to be attached to a corresponding support structure can.

Such an arrangement of the point holder within the double-pane insulating glass is based on the disadvantage that the through-hole in the inner glass pane, through which the shaft of the point holder extends outwardly, must be sealed in order to maintain the insulating effect of the insulating glass. The sealing of the double-pane insulating glass disclosed in DE 201 10 192 U1 is relatively complicated.

For this purpose, on the one hand a arranged between the two glass panes and sitting on the shaft of the point holder spacer sleeve frontally provided on one of the inner glass pane facing side with a first sealing ring which seals the gap against the through hole. On one side of the inner glass pane facing away from this end face of the spacer sleeve, on the other hand, an annular sealing element, which is provided on the inner glass pane with a second sealing ring at the end, is arranged in a clamping manner between the inner glass pane and the shaft of the point holder projecting beyond the inner glass pane. This second annular sealing member seals the through hole to the outside.

In addition, the annular sealing element of the point holder has an injection opening, which is accessible from the outside and opens into a space between the spacer sleeve and the annular sealing element in the through hole of the inner glass pane. In this space a sealant is introduced for hermetic sealing of the through hole, which completely fills the gap.

If, contrary to expectations, a leak occurs in such a point holder, air can penetrate into the space separating the two glass panes. Consequently, the moisture contained in the air can destroy the insulating effect of the insulating glass. In addition, the moisture contained in the air can condense and precipitate on one of the two glass panes. Since the gap between the two glass panes is not accessible, such a precipitate can not be removed. Rather, this precipitate clouds the double-pane insulating glass milky. This has the consequence that the double-pane insulating glass must be replaced.

From EP 0 314 120 B2 a facade panel made of an insulating glass is known, the outer or outer glass pane is formed from a single-pane safety glass. The tempered safety glass is designed such that it extends over the edge bond of the insulating glass and thereby forms a protruding edge region, which may be provided on its back with undercut blind holes, in each of which an expansion body and a spreading element for fixing a substructure is arranged. The substructure can additionally be glued to the single-pane safety glass by means of an adhesive layer. This substructure is used to attach the facade panel to a support structure which is attached to a building exterior wall.

A disadvantage of this facade panel and its external arrangement of the single-pane safety glass is that the blind holes can not be arbitrarily arranged on the single-pane safety glass, but rather only along the protruding edge region of the same.

From DE 199 39 172 Al a point holder for connecting an insulating glass to a substructure is known, which is glued to an outside of the insulating glass with the same by means of an adhesive only

DE 198 59 888 C2 also describes a point mount for connecting an insulating glass to a substructure, which, however, is positively connected to the insulating glass. The insulating glass is on the substructure facing side glued over the entire surface with a mounting glass, which is provided with a hole which is widened conically insulating insulating glass side and forms an undercut blind hole due to the bonding of the mounting glass with the insulating glass. In this blind hole, a part of a holding element is arranged, which has a conically widened end, which is inserted in the conical widening of the hole of the fixing plate and braces the holding element with the fixing plate.

The present invention has for its object to provide a facade for the cladding of buildings, in addition to a variety of point holders and a variety of to be fixed to a primary structure supporting structures for receiving the point holder and a plurality of facade elements made of insulating glass, in particular double-pane insulating glass, provide.

The object is achieved according to the invention with the features specified in claim 1. Preferred embodiments of the invention are subject of the dependent claims.

In addition, the present invention has for its object to provide a point holder for a facade element made of insulating glass, in particular double glazed insulating glass, which requires no additional sealing over the sealing of the bonded edge composite.

Moreover, the present invention has the object to provide a point holder, which allows an elastic attachment of the facade element made of insulating glass to the support structure.

In addition, the present invention has for its object to provide a point holder, which can be arranged arbitrarily on the facade element. The facade according to the invention comprises a plurality of supporting structures to be attached to a primary structure for receiving point holders for facade elements made of insulating glass, a plurality of facade elements made of insulating glass and a plurality of point holders for attachment to the facade elements of insulating glass on the one hand and for fastening the facade elements of insulating glass to a the supporting structures on the other.

According to the point holder is anchored on the one hand in the facade element and on the other hand preferably glued by means of a special adhesive for glass in the form of an adhesive tape with the facade element.

For anchoring in the facade element, the point holder has at least one expansion body in the form of an expansion anchor and at least one spreading / fastening means for spreading the expansion anchor on the one hand and for anchoring the point holder in the facade element of insulating glass on the other.

For this purpose, the facade element has, according to the invention, an insulating glass with an inner pane of glass formed as toughened safety glass (ESG) and at least one further pane of glass arranged adjacent to this inner pane of glass. On one of the at least one further glass pane facing away from the inner glass pane is provided with at least one undercut blind hole in which the expansion body is arranged in the form of an expansion anchor for anchoring the point holder in the facade element.

Compared to the disclosed in DE 201 10 192 Ul point holder, the present point holder of the facade according to the invention for anchoring does not extend through the inner glass of the facade element made of insulating glass. Consequently, the effort to be driven according to DE 201 10 192 Ul for an additional hermetic seal at the point of passage through the insulating glass is eliminated. In addition, the assembly of such a facade element made of insulating glass significantly simplified by the elimination of the additional hermetic seal.

In a preferred embodiment of the invention, the expansion anchor of the point holder on the one hand on an expansion element and on the other hand on a holding and stop element. Preferably, the expansion anchor of the point holder is formed with an internal thread, wherein the internal thread of the expansion anchor can extend from the holding and stop element to the expansion element expediently.

Preferably, the expansion element of the expansion anchor is provided with expansion lugs, which engage in the installed state of the expansion anchor in one of the blind holes of the inner glass of the facade element in the undercuts of the blind hole.

The holding and stop element of the expansion anchor is preferably cylindrical. Alternatively, the holding and stop element of the expansion anchor can also be formed four or more polygonal.

As a spreading / fastening means for spreading the expansion dowel on the one hand and for fixing the point holder to one of the facade elements of insulating glass on the other hand is a screw, preferably a cylinder screw with hexagon socket.

In a particularly preferred embodiment of the invention, the facade element is designed as a double-pane insulating glass, in which an outer glass pane is arranged by means of a spacer profile made of aluminum at a desired distance from the inner glass pane. The inner and outer glass sheets are glued to the spacer profile. In the . Disc space is either dried air or a noble gas. The edge joint formed by the spacer profile and the two glass panes is hermetically sealed by means of a silicone sealant.

In a further particularly preferred embodiment of the invention, the inner glass pane of the facade element is glued on a side facing away from the outer glass pane with a glass pane formed as teilvorgespanntes glass (TVG) by means of a film of polyvinyl butyral (PVB) as an intermediate layer material. This glass pane designed as partially tempered glass (TVG) has in its corner regions in each case a through hole through which the expansion dowel of one of the point holders extends into the blind hole of the inner glass pane.

The point holder of the façade according to the invention consists essentially of a holder axis and an axle receptacle for the holder axis.

The spreading / fastening means attached on the one hand the holding and stop element of the expansion anchor to the holder axis of the point holder and on the other hand, the holder axis of the point holder to the inner glass of the facade element.

At its facade end, the holder axis has a cylindrical recess for receiving the preferably cylindrical holding and stop element of the expansion anchor. In order to import the spreading / fastening means of the point holder at the end facing away from the facade element end of the holder axis through the holder axis in the expansion dowel, the holder axis is advantageously formed hollow.

In order to form a suitably designed end face required for bonding to the inner glass pane of the façade element, the holder axis of the point holder can be produced during the machining or turning from a corresponding blank having a large diameter. Conveniently, to form the required for the bonding with the inner glass pane of the facade element end face on the facade side paragraph alternatively a ring element can be arranged, which is preferably welded to the shoulder of the holder axis. For example, such a ring element could be laser-welded to the shoulder of the holder axis. Consequently, the holder axis could be made in the machining or turning of smaller blanks, which would be useful for reasons of material savings in the machining.

At the end facing away from the facade element, the holder axis is provided with a thread for receiving a corresponding nut.

The Achsaufhahme, in which the holder axis is arranged, has a socket and an insert for the socket. To accommodate the holder axis of the use of the axle is provided with a suitably cylindrical recess.

In a preferred embodiment of the invention, the socket and the use of the Achsaufhahme advantageously form a conical press connection or cone connection, wherein the insert has a conical portion and the socket is provided with a conical recess for receiving the conical portion of the insert.

When inserting the holder axis in the use of Achsaufhahme the end facing away from the facade element of the holder axis protrudes expediently beyond the insert.

On a side facing the fastening device, the bushing of the axle receptacle has a hub-shaped end which carries a thread on its entire inner side. In this hub-shaped end of the socket, a lid screwed with a thread.

To form a closed space within the hub-shaped end of the sleeve, a spacer ring is arranged between the lid and the conical portion of the insert, which is braced when screwing the lid into the socket against the conical portion of the insert.

hi this closed space of the socket protrudes the facade element facing away from the end of the holder axis. On the thread of this end of the holder axis, a washer is placed on the conical recess of the socket for clamping the conical portion of the insert and a corresponding nut turned on.

The cover of the socket further has a cylindrical recess with a thread into which a threaded bolt for fixing the point holder is screwed to the fastening device of the facade according to the invention. By means of a lock nut, the threaded bolt is fixed relative to the lid.

Apart from the elastic silicone insert of the axle holder, the point holder of the façade according to the invention is expediently made of a stainless steel.

According to the invention, the fastening device for one of the point holders is adjustable in at least two mutually orthogonal directions. For this purpose, the fastening device for one of the point holder has an outer body fixed to one of the supporting structures with a recess and a in the Recess of the outer body arranged to the supporting structure movable inner body with a recess which serves to receive the threaded bolt for fixing the point holder to the fastening device. The inner body is adjustable relative to the outer body by means of adjusting and fastening means in at least two mutually orthogonal directions.

Preferably, the fastening device is adjustable in two mutually orthogonal directions.

The movable arrangement of the inner body of the fastening device allows on the one hand a precise alignment for receiving the point holder in the attachment of the facade element to the supporting structure. On the other hand, this movable arrangement of the inner body of the fastening device allows the point holder a translational movement possibility in one of the at least two mutually orthogonal directions to compensate for temperature-induced deformation of the facade element.

For receiving the adjusting and fastening means, the inner body expediently has a plurality of through-holes, whereas the outer body for receiving the adjusting and fastening means expediently has a plurality of elongated holes.

To introduce the spreading / fastening means M _SB in the expansion anchor SD, the holder axis 2 is hollow. At the end facing away from the facade element FE end of the spreading / fastening means M _SB is screwed through a second, cylindrical recess 8 of the holder axis 2 and a through hole 10 in the interior of the holder axis 2 in the expansion anchor SD. At the transition from the cylindrical recess 8 to the through hole 10 of the head of the cylinder screw is located on an inwardly projecting, circumferential projection 12.

Due to the high clamping force required for anchoring the expansion anchor SD on the one hand and the direct contact of the metallic Spreading element With the blind-hole wall of the inner glass pane GS1 of the facade element FE on the other hand, the inner glass pane GS1 is designed as single-pane safety glass (ESG). An outer glass pane GS2 of the facade element FE is arranged at a desired distance from the inner glass pane GS1 by means of a spacer profile AH made of aluminum. The two glass panes (GS1, GS2) are glued to the spacer profile AH. In the space between the panes ZR is dried air. The edge joint RF formed by the spacer profile AH and the two glass panes (GS1; GS2) is hermetically sealed by means of a silicone sealant (not shown here).

For this purpose, the inner glass pane GS1 in its corner regions on each of the outer glass plate GP2 side facing away from an undercut blind hole SL for receiving one of the spreading elements SE.

In a particularly preferred embodiment of the invention (FIG. 4), another or second safety glass pane GS3, which is preferably in the form of partially tempered glass (TVG), is glued to the first safety glass pane GS1 by means of an adhesive film KF made of polyvinyl butyral (PVB) as interlayer material , so that the first and the second safety glass pane GS1, GS3 form a laminated glass pane, which in turn forms the inner pane of the insulating glass. The second safety glass pane GS3 has in its corner regions in each case a through hole LQ _S3 , through which the expansion anchor SD of one of the point holders PH extends into the blind hole SL of the first, relative to the laminated glass outer safety glass pane GSL. An advantage of this embodiment is that in case of failure of the positive connection between the expansion element Es of the expansion anchor SD, which is arranged in the blind hole SL of the first safety glass GSl, and the first safety glass GSl a Restragfähigkeit by the then supporting anchoring of the through hole L _G s _{3 of} the second safety glass pane GS3 seated holding and stop element E _H A of the expansion anchor SD is ensured.

To form a suitable for bonding with the inner glass GSl of the facade element FE, appropriately trained face 14, the holder axis 2 of the point holder PH is provided at its facade end with a paragraph 16 on which a ring member 18 is seated, which laser-welded to the shoulder 16 is. This ring member 18 is formed and arranged on the shoulder 16, that both its facade side end face 14a flush with a facade side end face 14b of the shoulder 16 and its facing away from the facade element FE end face flush with a facade element FE facing away from the end face of the paragraph 16. In this case, the useful for the arrangement of the adhesive K face 14 is composed of the facade side end face 14a of the ring member 18 and the end face 14b of the shoulder 16 of the holder axis 2 together.

The Achsaufhahme 4, in which the holder axis 2 of the point holder PH is arranged, has a sleeve 20 and an insert 22 for the sleeve 20, which together form a conical interference fit or conical connection.

The bush 20 of the axle receptacle 4 has on the facade side a through hole 24, through which a cylindrical section ZA of the insert 22 extends completely. At this through hole 24 includes a tapered in the direction of the facade element FE conical recess 26, in which a conically shaped portion KA of the insert 22 is arranged. At the transition from the conical recess 26 to the through hole 24, the bushing 20 has an inwardly projecting, circumferential projection 28 on which the insert 22 rests with a shoulder 30.

hi a cylindrical recess 23 of the insert 22, the holder axis 2 is inserted to the stop on the facade element FE facing away from the end face of the shoulder 16. The holder axis 2 penetrates completely the Recess 23 of the insert 22 and projects beyond an end face of the insert 22 facing away from the facade element FE. This projecting end of the holder axis 2 is provided with a thread 32, on which a corresponding nut 34 is turned up for clamping the conical connection. Between the nut 34 and the facade element FE facing away from the end face of the insert 22, a metallic washer 36 is also arranged.

Fastening device side, the sleeve 20 of the axle 4 is provided with a hub-shaped end 40 which carries a thread 40 b on its entire inner side into which a cover 42 is screwed with a thread 44. Between the cover 42 and the conical portion KA of the insert 22, a spacer ring 38 is arranged to form a closed space R, which is clamped during insertion of the cover 42 in the hub-shaped end 40 against the conical portion KA of the insert 22. The lid 42 also has a cylindrical recess 45 with a thread into which a threaded bolt 48 is screwed for fastening the point holder PH to the fastening device BV of the facade F according to the invention. A lock nut 46 fixes the threaded bolt 48 to the cover 42.

Characteristic of the point holder PH, the insert 22 of the axle 4 as a non-metallic, elastic body, namely as a silicone insert, formed, which gives the point holder PH a rotational movement possibility. As a result, the facade elements FE of the façade F according to the invention can bend slightly elastically when wind pressure or wind suction forces act.

With the exception of this silicone insert for the socket 20 of the point holder PH of the facade according to the invention F is made of stainless steel.

A provided with four point holders PH facade element FE is connected by four fastening devices BV (loose and fixed bearing) tolerance-compensating with one of the supporting structures TK, wherein two of the four Fixing devices BV as a floating bearing and the remaining two fastening devices BV are designed as a fixed bearing.

The fastening device BV for the point holder PH is according to the invention in two mutually orthogonal directions, which are here marked with X and Y, adjustable. For this purpose, the fastening device BV has an outer to the support structure TK fixed body BVl with a four-edged recess 52 and disposed in the four-cornered recess 52 inner to support structure TK movable body BV2 with a cylindrical recess 54, wherein the inner body BV2 relative to the outer body BVL is adjustable by means of adjusting and fastening means in two mutually orthogonal directions.

As a result, a precise alignment of the fastening device BV for receiving the point holder PH is possible in the attachment of the facade element FE.

Through the cylindrical recess 54 of the inner body BV2 extends the threaded bolt 48 which on a point holder PH side facing the inner body BV2 by means of a first nut 50a and on a side facing away from the dot holder PH side of the inner body BV2 by means of a second nut 50b the inner body BV2 is fixed.

The fastening device BV shown in FIG. 5 is based on the function of a movable bearing, which allows the inner body BV2 to be translationally movable with respect to the two directions X and Y to compensate for temperature-induced deformations of the facade element FE. For this purpose, the adjusting and fastening means comprise four bolts which form two mutually orthogonal, offset pairs of bolts.

A first aligned in the X direction pair of bolts, which allows the adjustment of the inner body BV2 in the X direction, comprises a bolt 60 and a Bolt 64, whereas a second oriented in the Y direction pair of bolts, which allows the adjustment of the inner body BV2 in the Y direction, a bolt 62 and a not visible here pin 63 includes.

The two bolts (60, 64) of the first pair of bolts each extend through one of two aligned in the X direction through holes 56a in the inner body BV2 and two aligned in the X direction slots 58a in the outer body BVL. In contrast, the two bolts (62, 63) of the second pair of bolts each extend through one of two aligned in the Y direction through holes 56b and two aligned in the direction Y, but not visible here, slots 58b in the outer body BVL. By means of retaining rings 68, the bolts (60; 62; 63; 64) are fixed relative to the outer body BV1.

In the case of a fixing device BV designed as a fixed bearing, at least one of the bolts (60; 62; 63; 64) would be replaced by a screw, preferably a hexagon screw, in order to prevent the possibility of movement of the inner body BV2 with respect to one of the two directions X and Y. ,

If, for example, the bolt 62 were replaced by a hexagon head screw, the head of which rested on the washer 70, the possibility of movement of the inner body BV2 in one of two X directions could be achieved by turning a corresponding nut onto the screw shaft at the opposite end 80 Prevent hex screw against outer body BVL. The same applies to the suppression of the possibility of movement of the inner body BV2 with respect to one of two Y directions.

For attachment to the supporting structure TK, the outer body BV1 has both four through holes 66a aligned in the direction X and four through holes 66b aligned in the direction Y (FIG. 6). The support structure TK for receiving the point holder PH consists of a closed support frame, which is arranged directly behind the facade elements FE (Figure 2). In the corner areas on the inside 67 of this support frame one of the point holder PH is connected to the support frame. By means of two flanges 68 of the support frame in turn is attached to a primary construction not shown here with posts and bars.

The weather gaps WF or glass joints (FIG. 3, FIG. 4) resulting from the arrangement of the facade elements FE are sealed by means of silicone profiles pressed into the weather joints WF and additionally sealed with a silicone sealant. Such a sealing of glass joints as such is known to the person skilled in the art. For this reason, in the present embodiment of the invention has been dispensed with a representation of the sealing of one of the glass joints.
