A reinforcement (4,5) for fixing the rail is provided at each intersection between the rail and a post. An independent claim for an expandible clamp element used between 2 interfitting parts is also included.

Description

The invention relates to a mullion and transom façade accordingly the preamble of claim 1.

In mullion-transom facades is a substantially vertical or horizontally extending support profile provided. That the Façade elements bearing fastening profile is either pressed directly on the support profile or with appropriate Fasteners attached to this. The supporting profiles themselves consist of a metal, such as steel, aluminum or The like, however, for the facades and support profiles Used wood. Such facades are, for example, too referred to as wood aluminum facades.

Be on the horizontally extending fastening profiles partially turned off large windows with considerable weight.

Due to the off-center load corresponding forces act on the bar profile. It comes to tilting the bolt construction because of the burden.

The invention has set itself the task of a mullion-transom façade, as described above, available too in which a stable and torsionally stiff Connection between the horizontal and vertical facade element consists.

To solve this problem, the invention is based on a Post and beam facade, as described above, and proposes before, that in the junction of posts and bars a bolt torsion-fixing, defining stiffening is provided.

The proposal according to the invention is a stiffening on Node between pole and latch. The node is doing through those areas on the post or bar defined, which in the finished facade in operative connection stand or touch each other. The arrangement is according to of the invention chosen so that the stiffener in the post or Bar is integrated and so the design of the facade is not impaired. By the proposal according to the invention is the Node stiffened so that even at a considerable Load of the bolt this distortion remains.

The invention proposes a total of three variants, such as this can be achieved. In the first variant, how will be described below, two interacting with each other Parts suggested. In the second variant, the Stiffening of a profile projection of the arranged on the bolt Fastening profiles achieved, this profile projection then attached to the post accordingly and / or if necessary directly above the post or on top of the post Post arranged profile is able to remove the load. In the third variant, the two aforementioned Suggestions combined, which is even more significant Increasing the stiffening results. With these Variants make it possible to remove even higher glass loads or alternatively, the profiles accordingly slimmer too dimensioning at the same load transfer, for example, the To be able to positively influence the design accordingly.

In a preferred variant of the invention it is provided that the stiffener consists of two parts which can be joined together, with a first part at the side of the post and a second part is arranged on the front side of the bolt. Plugging means in this context, the insertion of the two parts into each other and their longitudinal mobility as a sliding movement. Between the first and the second part is a channel formed, which preferably over the entire length of the part extends. The attached to the front side of the bolt part is according to an embodiment of the invention on the bolt front side placed. According to a further embodiment of the invention However, it is intended to sink the part in a recess. In this way, the front side of the bolt is directly at the post, although between the posts and bars the Reinforcement is located. In this way it is achieved that no gap between the posts and bars. The two-piece Design of the stiffener has the advantage that this easy to assemble and, for example, already on the workshop side can be prepared, reducing the assembly effort the construction site is shortened considerably. The inventive Arrangement also allows that the horizontally extending Riegel can be retrofitted into the facade. By the invention, therefore, for example, a transformation of Post and beam façade easily possible. This works even with existing facades, with corresponding Elements equipped to be supplemented. The arrangement of a Channel between the two parts serves to appropriate To include clamping elements and the like. Since preferably the parts are made as profiled goods, extends Conveniently, the channel also equal over the entire length of the part.

Both parts are fixed by bracing against each other. The Bracing is advantageously carried out by means of a tensioning element that can be used in the channel formed by the parts or is screwed. By bracing the two parts These are set to each other and thus the entire Reinforced stiffening, so for transmitting corresponding Loads usable. It cleverly the arrangement is so chosen that even the two be joined together Elements, ie posts and bars, exactly through the stiffening are positioned.

In a further variant of the invention it is provided that the parts to each other, at least during the attachment of the Riegels at the post, have a fitting-in game. This installation play of course facilitates the assembly of the Tie at the post. The installation play allows a certain Alignment of the two elements to each other in order to optimize this align and also compensate for certain dimensional tolerances. is but then the bolt is placed in the desired position on the post, so by the use of the clamping element, as described, eliminated this installation play and the two parts tightly clamped together.

According to the invention it is proposed that the cooperating Parts of several channels, each for receiving a tensioning element, exhibit. It is sufficient in the first variant of the invention already off, with a clamping element success of the invention to realize. But are the parts that work together formed several channels, so it is of course favorable by increasing the number of tensioning clamping elements to achieve an improvement in stability. The The invention thus comprises both solutions in which only one Clamping element is used, as well as solutions in which a variety of clamping elements (two or more) used become.

The part attached to the post almost extends over the entire post width. In this way, a large contact surface achieved, reducing the strength of the mullion-transom facade is increased. The part attached to the post extends however, according to an embodiment of the invention, almost only about entire post width so that it fits well in a recess insert and is not necessarily visible from the outside. Correspondingly long is the part attached to the bolt, so that both parts intermesh over their full length.

In a variant according to the invention for this purpose is also provided that the part attached to the post almost over the entire Bar width extends. There are also post-and-beam facades known that a narrower, smaller building bolt have opposite a larger post. The advantage of this Embodiment is that as possible, the entire surface of the Riegel, minus a margin to cover the fortification, is exploited.

In this respect, this invention includes both solutions, depending on the in which proportions posts and bars installed to each other become.

Advantageously, the clamping element acts on at least two Channel areas on the parts spanning a. Preferably lie these areas in the front and rear channel area. This can done by two short pins or screws, by both Ends of the channel are introduced into the channel. From The clamping force is introduced in front and from behind. The bracing However, it can also be done by means of a pen, the extends over the entire length of the channel and the Clamping force over the entire length of the parts extends. By distributing the clamping force over the entire length of the parts There is no game that can make you wobble. By the Distribution of the clamping areas on the front and rear Channel area is, without the bracing over the entire Length takes place, but evenly distributed. cleverly The fact is exploited the fact that the parts relatively are long, so almost over the entire width of the Extend the post, and the channel areas on which the Clamping element acting on the parts, as far as possible are away from each other. Mechanically, it turns out then, that a relatively long lever at its ends is held or fixed what the torsion-free or Low-torsional absorption of higher loads easier.

It is by the inventive proposal with the clamping elements also achieved that a flat tensing the Riegel at the post is possible. Namely, two clamping elements offset from one another in the manner described, this results in two times two channel areas, where the Clamping element is effective, the arrangement is essentially flat and with skillful design only a little smaller than the cross-sectional area of the bolt. By a possible flat tensioning of the bolt on the post is but achieved a correspondingly high stability of the stiffener.

The exact execution of the clamping element according to the invention is later described in detail.

At least one of the parts is substantially U-shaped. This U-shaped part substantially decreases positively the second part in itself. This second part may consist of a profile part whose cross section at least the width of the U corresponds, so that both legs of the U include the profile part between them. The thigh The U's lie directly on two opposing Outside of the profile part. For an off-center load for example, the bolt through the on the mounting profile Overlying facade elements, the Latch, characterized in that the profile part is received by the "U", do not twist.

According to a further embodiment of the invention, the second Part of the stiffener also from a U-profile, with the Legs of this U-profile with their outsides on the insides abut the leg of the first part.

According to a further embodiment of the invention, the second Part C-shaped, that is, the ends of the legs of the U have inwardly directed bends. This C-shaped part surrounds with the bends at least partly the first part. In this way is the contact surface enlarged between the first and second part, whereby the torsional strength is increased. So that from the Legs angled ends - so the bends - the can embrace the first part is either the first part with attached to the bolt a certain distance, or it is provided an undercut, which absorb the bends.

For example, a part that has undercuts can have a T-shaped cross-section. The T is with his vertical foot attached to the post or latch, while the C-shaped Part of the crossbeam of the T absorbs. The crossbeam is dimensioned such that it with its end faces on the insides of the legs of the U or the C's positive fit. The bearing surface should be as possible be chosen large, so that when applying a torque to the Latch, in the stiffening no play exists and so the Power is dissipated over the post.

The parts are formed so that one part of the respective completely absorbs the other part. This means, if both parts are inserted into each other, none of the Parts over the other. This will be a very compact design for the stiffener formed, which is fine between posts and bars accommodate or slightly in a recess is recessed on the front side of the bolt can be.

The bends at the ends of the legs of the U are in hereinafter referred to as supernatants. Not just the first part is U-shaped with provided at the ends of the legs supernatants formed, but, according to a variant of the invention, the second part is also U-shaped with the Ends of the legs provided on supernatants.

The overhangs of one of the parts can be aligned towards each other be. By this configuration, the substantially C-shaped Training one of the parts formed. After another Variant, the supernatants are aligned away from each other.

This projection limits the parts edge-like. At the first Part is the edge to the outside and the second part inside directed.

An essential feature of a variant according to the invention consists in that the end overhang of the first part opposite the end-side projection of the second part is aligned. In this way it is possible that the two Supernatants interact with each other. The two parts are bordered by the supernatants.

By means of a sliding movement along its longitudinal axis the two parts are engaged with each other. A movement perpendicular to the longitudinal axis is thus locked out. Both parts are holding together. These Bracket is sufficient to lock the latch opposite the jamb Fasten. To avoid that the bolt against the Posts warps, the two parts are designed in such a way that the outer dimension of the first part to fit in the inner dimension the leg of the second part sits. In this way results a torsion-free connection between posts and Bars.

To a suitable connection of the two parts together received, it is immaterial whether it is the interior Part around a U-shaped with outwardly angled supernatants, or a profile with a rectangular cross section, or around a tee acts. It is essential that this part with his Outside dimensions abut the legs of the outer part.

In the execution of the inner part with angled outwards Overhangs and the outer part with after inside angled projections are the end faces of the Projections on the thighs of the other part.

According to one embodiment of the invention, the contact surfaces are at spaced apart composite parts. To this Way, a channel or two channels is formed, which limits are from thighs and supernatants.

According to one embodiment of the invention, it is provided Part multi-element execute. The individual elements of the Parts are located, for example, aligned on the post and / or on the bar. The aligned arrangement causes the individual elements together like a longitudinal, profile-like part to act. The design the individual elements, for example, shorter ones Profile sections, it allows in a simple way the invention to adapt to the different post and bolt dimensions. Also Here it is again advantageous, the first and last element spaced as far as possible to order a To obtain as large as possible plant area and clamping range.

The invention also makes it possible that, for example, on the Post the individual elements of the part are arranged or at the bar. Also, a combination of these two suggestions possible, for example, such that both the part of Post as well as the part of the bolt each multi-element is formed and these elements cooperate within the meaning of the invention.

Again, it is possible by a sliding movement this Engage elements with each other. These subelements can be placed directly against each other or even spaced apart be arranged on the post or bar. Training the sub-elements is the same as a part, which extends almost over the entire width of the post. In cross section here they also have a U-shape with a right angle molded projections on or the female part is in cross-section C-shaped and the recorded part in cross section T-shaped. In plan view are different these sub-elements to the effect that they are opposite to a rectangular Training, as previously described, an equally polygonal, may have round or oval contour.

Advantageously, it is picked up by the C-shaped part Part formed like a button, so that the supernatants of the C's Head of the button absorbs. The neck of the button is located then between the supernatants of the C-shaped part.

By bracing the recorded first part against the receiving second part they are fixed to each other.

The clamping takes place by inserting a tensioning element, For example, screwing a screw in the channel, so that slipping of both parts now in their longitudinal orientation is prevented. For clamping it is also possible pins, insert a wedge or other parts in the channel.

However, the legs of both parts should not be different from each other be pressed away, otherwise the desired fit no longer is guaranteed. That is, the diameter of the screw is allowed be just as big as the distance between the legs of both parts from each other. The front sides of the supernatants remain on the legs of the other part fitting. By the Inserting a screw, a wedge or other clamping element in the channel, however, causes at a loose connection of posts and bars to each other the two Parts are moved further into each other. To this It is achieved that the bolt pressed against the post is, creating a gap-free connection between posts and Bar is reached. After clamping the two parts together is a torsion-fixing attachment between Bar and posts reached.

In this embodiment of the parts, the cross section is over the entire length of the channel the same. The thread of a screw cuts into the material of the parts and fixes on this way both parts together. According to another embodiment The invention is already threaded in the parts provided, in which the clamping screw are used can. In both cases, the channel is screwed through the clamping screw widened, so that the two parts together be tense. It can be with these clamping screws are short screws acting from either side or only be screwed into the canal from one side. To A further embodiment of the invention is provided which two parts with a pin to brace each other, wherein the diameter of the pin is slightly larger than that Diameter of the channel itself. Again, it is possible that It can, however, cause distortion by means of a pin also pins from both ends of the channel pressed into the channel become.

According to another variant is provided, the channel in one certain area to be provided with a constriction, so that the Diameter of the clamping element corresponds to the diameter of the channel and the tension effect occurs only in the area of the constriction. In this way, since in most cases the channel only accessible from one side, a clamping effect several places in the channel are effected. With a clamping element, has the differently shaped sections, is it is possible to set the clamping points targeted. For example the narrowing is provided in the end region of the channel, wherein the cross section of the clamping element is slightly larger than the Cross-section of the canal in the area of the narrowing, but smaller is the cross section of the channel in the remaining area. By Insertion of the clamping element has the effect of clamping in the area the narrowing. To tighten in the beginning of the channel to achieve, is provided, the clamping element in this area with a diameter greater than that of the channel, so that with inserted clamping element bracing in this Area is effected. It is also possible, of course several places in the channel a corresponding clamping effect, that is, to form a channel region as described above. Therefor is suitably a gradation of the clear diameter of the clamping element in relation to the channel or chosen his constrictions, namely such that the constriction at the rearmost area is the largest and the diameter of the Tensioning element therefore smallest, so this area of the Clamping element passed through all previous constrictions can be. Thus, it is possible more than two To create channel areas where the clamping elements his Tensioning effect on the two parts unfolded.

In a preferred variant of the invention it is provided that the clamping element over a portion or over the entire length of the channel and stretching on the parts acts. It is not mandatory that the Clamping element only over a certain, short area of the channel extends, according to the invention, it is possible that possible the entire length of the channel used by the clamping element is or the clamping element is also shorter.

Cleverly provided that the clamping element extends at least into the region of the narrowing in the channel.

In this variant, it is provided that the constriction, the in the rear, the insertion opening of the clamping element on Channel is located remote end. In this area is the Clamping element for the second time in the context of the invention an expansion cause the two parts. So it's enough the length of the clamping element to be dimensioned so that this flat only this narrowing is achieved and it has a tightening effect. conveniently, but this narrowing is in the back of the canal, possibly at this rear end, provided.

The consequence of inserting the clamping element in the channel, in particular in the area of the constriction, is that the channel widened and the parts of the stiffener are pressed together. But this pressing apart presses the merged two parts together so that they fixed connection are and thus also those with the respective parts connected Make post and bolt to each other firmly.

The combination of constriction and screwing is also possible. Here is the area of the clamping element that is used in the State cooperates with the beginning region of the channel, formed with a thread that holds the two parts in this area clamped together. The constriction is advantageously produced by deforming the projections of the parts. In this way it is possible to narrow the constriction only in to provide a direction so that the height of the channel is smaller is as the width of the channel.

The dimensions of the tension element one side and the arrangement the narrowing in the channel on the other hand is chosen so that the tip of the clamping element then prefers the constriction interacts when the thread is in the starting area of the channel intervenes. In this way, the clamping element so far in the Channel can be inserted until the thread engages and through Further rotation of the pin comes the tip of the clamping element in contact with the constriction, but can by the rotation easily be introduced into the narrowing.

In a preferred variant of the invention it is provided that the clamping element consists of a pin, which is a smooth Pin area and a threaded area. Through the threaded area, it is possible, the clamping element in to fix and fix the channel. At the same time causes the thread also a nip of the parts.

It is envisaged that the smooth pin area in the area the tip of the pen is provided and the area with the Thread is disposed at the opposite end of the pin. In this respect, the clamping element so illustrated is not like a Screw formed, as with a screw normally the Thread at the lower end, the screw head remote end, is arranged. It should also be noted that the top of Clamping element is also used clamped. In a Namely, preferred variant of the invention is provided that the dimensions of the clamping element on the one hand and the arrangement the constriction in the channel on the other hand is chosen so that the Tip of the clamping element preferably only then with the constriction cooperates when the thread in the beginning of the Channel already intervenes. So will be in two places at the same time of the channel, ie two channel areas, in the same way Spreading causes and so the two parts set to each other.

These are, for example, self-tapping screws provided or the channel already has a corresponding Thread or a thread-like ribbing.

According to a further embodiment of the invention is a clamping element provided, consisting of two mutually parallel There is a pin connected by a bracket are. This clamping element is advantageously made made of a bent wire. The diameter of the pins is over their entire length the same, so that the clamping effect only in Area of narrowing in the channel acts. After another execution invention, the pins on a bend, the interact with the constrictions in the channel when the bracket is inserted. In this way, the clamping effect is increased, so that the compound is given a higher strength.

It is intended to insert the stirrup only in the channels, when both parts engage with each other. To however, it is a further embodiment of the invention possible to insert the bracket already in the female second part and only then the first part to be recorded in the to take in the receiving part. The clamping effect then occurs when bending and narrowing are aligned. In order to Prevent the strap from going too far into the receiving part slips in, is provided, the end of the temple on which both pins are interconnected to run wider, as the inside dimension of the two legs of the female part to each other. Advantageously, the bracket dominates the outer dimensions the receiving part not. To the location of the temple in the receiving Part to fix, the ends of the pins are bent and surround the receiving part on the front side.

In a further variant of the invention is a stop one of the parts provided, which prevents the male Part all too far into the receiving part slips or slip out on the other side. For this purpose, a stopper is provided on one of the Parts molded or attached. This stop is advantageously provided on the male part, wherein the Width is greater than the height of the female part. This Stop consists of a T-shaped component, the is advantageously formed or punched out of a metal sheet is, wherein the crossbar of the T is longer than the distance the leg of the male part.

According to one embodiment of the invention is provided, one of Parts with its longitudinal axis parallel to the post axis align. The part connected to the latch, is attached to the front of the bolt. Through a movement transverse to the longitudinal direction of the post are both parts stuck together. For a vertically oriented facade Thus, the insertion direction from front to back or from the back to the top. According to this embodiment it is provided the part taken up by the outer part with a stop provided so that the bolt is not absorbed by the recording of the first part can slip through.

According to another embodiment, the two parts of the stiffener transversely to the alignment of the post twisted on posts and bolts attached. With upright facade is thus the Latch inserted horizontally between two posts.

With the execution of a connection described so far the parts outside on the post or on the front side of the Bolt fastened. However, another variant is provided that the stiffener, consisting of the two parts, find in a recess in the bolt recording. To this Purposes, the recess pocket-like design. In arrangement the stiffening perpendicular to the longitudinal direction of the post is advantageously the recess in the direction Facade outside open. From this side is the bar inserted between two posts. The recess may be in the direction Facade inside also be open. However, to the inward facing of the facade a continuous Appearance is advantageously the recess closed in this direction.

To the outside of the mullion-transom construction are for the Fixing of facade elements fastening profiles provided. These fastening profiles are directly attached to the supporting structure pressed or usually on the posts and attached to the bolts by means of screws. According to the invention is provided that the second part openings for receiving Having fastening means, so that the fastening profiles this stiffener can be attached.

The openings are advantageously channel-like, so they in the production of a profile from which the parts the stiffening consist, for example, in the extrusion process can be made.

The parts of the stiffener are designed such that, for example the first part with the bolt and the second part with the post or the first part with the post and that second part are connected to the latch. Both parts are thus exchangeable. To achieve sufficient strength, The parts of the stiffener are made of metal. When Metals are iron, wrought iron or sheet metal. Prefers however, aluminum is provided as it is in processing in the Extrusion can be made, is easy and does not rust. Furthermore, it is provided according to the invention, that the parts of the stiffener also made of plastic, in particular Fiber-reinforced plastic, are created, including composite materials can be used.

It has proven to be advantageous, the depth of the nested To make parts smaller than half Width of the post. As a result, the recess on the front side of the post are not trained too deeply and it decreases the height of the edge boundary of the recess, the This has a higher stability, a higher counterforce can pick up and the risk of chipping the end wood strongly lowered.

According to another variant is provided for stiffening the arranged on the bolt mounting profile a Form profile overhang. This profile projection is with the Connected post. As already on the post itself a fastening profile is arranged, it is possible to the profile supernatant to arrange between posts and fastening profile. So that the fastening profile of the post smooth on the post rests, can for the profile projection a recess in the Post be provided. According to another embodiment has the attachment profile of the post a recess on, in which the profile supernatant stands. In this way you have to no gaps are made on the post and the both mounting profiles, that of the post and that of the Riegel, just get up on the post.

The attachment profile is by means of a fastener attached to the post. As fasteners own Bolts, rivets and the like, but screws are preferred used, since these are easy to attach to the post, are solvable again and in relation to smooth parts like Bolt or nails make a tighter connection with the post. The fastening profile of the bolt is in the range of Profilüberüberes prefabricated with the post. Because the mounting profile as well as being in touch with the tie at the same time connected posts and bars. By Pressure on the outside of the mounting profile, for example from above, resulting from the arrangement of facade elements causes a torque on the mounting profile exercised and the profile supernatant communicating with the post stands, supported on the post. This way will also a stiffening of the mullion-transom construction in Node reached.

According to a further embodiment of the invention, the fastening profile with the clamping elements on the stiffener and in addition attached to the bolt with other fasteners.

So far, a reinforcement has been described by means of two cooperating Parts and a stiffener by a profile projection, wherein both devices for stiffening each other can be combined. When fastening the bolt on the Post by means of the first variant of a stiffener can at the same time the fastening profile with a profile projection be provided in turn, in addition to the post in connection stands. For one thing, the connection between posts and solidified with it, on the other hand, the torque, the is exerted on the transverse mounting profile over the Derived from Pfesten.

In a preferred variant of the invention it is provided that the support profile is designed as a wooden support profile. The invention is preferably used in wooden support profiles to here to achieve sufficient stiffening. On it is the Invention but not limited, it can also be used by others Post-and-beam facades are used, in which the Example supporting profiles made of other materials, for example metal and so on. Furthermore, in a variant proposed the invention that the support profile made of plastic consists, for example, straw-filled plastic profiles Can be used according to their outer sides are laminated. The invention is very variable in this regard used. Of course, there are also appropriate composite materials or equipped with Stahlarmierung hollow profiles Plastic and so on can be used.

The invention is also directed to a spit-like tensioning element, which for clamping two interlocking Parts is provided, wherein the clamping element is an element head below which there is a first connection area followed and followed by a pencil report. The cross section of the smooth pen area is smaller than the upper one first Connection area. Advantageously, the tensioning element runs pointed in the front, with which it is in one another connection region is introduced, whose cross-section is smaller than the cross section of the first connection area. In the first connection region, the clamping element a thread on which it is the parts in the first connection area braced together. Cleverly, the pen area is which is below the first connection area located, equipped with a smooth outer surface. Just when the clamping element is helical and in the first connecting portion carries a thread is provided in that this pin area is opposite the first connection area stands back, so is designed narrower.

In this context, it is noted that all in the Regarding the clamping element described features of the mullion-transom façade as well as properties and so on, also with regard to the formulation of the spit-like invention Clamping element, transferable and within the meaning of the invention can be used and apply as disclosed. same for of course in the opposite direction. That means features that now only in connection with the pike-like clamping element are of course also considered as the post and Bolt facade disclosed as essential to the invention. there the invention includes not only the subject pike-like Clamping element, but also the use of a corresponding designed element as a clamping element, namely at a According to the invention, the post-rail façade parts of the stiffener to be stretched and set accordingly.

In Fig. 1 is a detail of the invention mullion-transom facade shown. The invention is shown here in view, the view is directed from outside to inside. Above and on the left (FIGS. 1 to 4) are each in a vertical one Partial sectional view of the arrangement of the fastening profile 2 on the post 1 with screws 3 (for the post 1) and on the left, the arrangement of the fastening profile 2a with the aid of Screws 3a are shown on the latch 1a.

It should be noted that in the aforementioned wood aluminum facades the facade elements (not shown) on the outside are arranged, therefore, the fastening profiles 2, 2a at the post 1 or bar 1a on the outside itself are located.

It is convenient, the fastening profiles 2, 2 a of aluminum produce, since the profile in an extrusion with Aluminum proven good to produce.

In Fig. 1 is a variant of the invention on the right side Solution shown. In the latch 1a is located the post 1 facing the end 13 a recess 9. Die Recess 9 is designed so that this only on the Outside (as shown here) is open in the inside directed inside but the node is completely in Wood executed to the consistent appearance of the wooden facade not to interfere. In this respect, the recess 9 pocket-like.

In the first variant, a first part 4 with one or a plurality of screws 6 attached to the post 1. This first Part 4 is designed for example as an aluminum profile and can be cut to length according to the desired dimensions. In cross section this first part 4 is essentially U-shaped, with the two legs 4a of the U an end-side projection 4b or edge, whereby the first part 4 at the leg end wider is like in the foot area.

This first part 4 cooperates with a second part 5, which with fastening screws 6a in the pocket-like Recess 9 is fixed to the front side of the bolt 1a. Also, the second part 5 is substantially U-shaped, exactly taken C-shaped, such that the two above Leg 5a at their ends an inner curvature, in a C-profile typical.

The dimensions of the first part 4 and the second part. 5 are dimensioned so that the outer dimension of the legs 4a and the supernatants 4b of the first part 4 a fit in the inner dimension of the legs 5a of the C-shaped second part. 5 results, that is, the supernatants 4b lie with their end faces on the inner sides of the legs 5a and the supernatants 5b on the outsides of the legs 4a. This will achieve that the two parts 4 and 5 along its longitudinal axis are nestable. Will be the first one Part 4 with one or more screws 6 on the post 1 fixed, it creates a torsion or torsion resistant Connection, if the second part 5 attached thereto is.

Conveniently, both the first and the second parts 4, 5 formed as an aluminum part. It gets through, for example gained an extrusion process. But it is also possible corresponding iron parts, forgings or bent sheet metal parts and so on here.

The assembly of the bolt 1a is carried out by attaching the Bolt 1a from the inside out. At first, of course, that was first part 4 mounted on the post 1 in the desired position, the Bar 1a has in its recess 9, the second part. 5 By plugging in from the inside out it is clear that the Recess 9 is oriented to the outside. Backside from the outside are the nested parts 4 and 5 accessible and now there is a screwing of the two parts 4 and 5 such that a clamping screw 8 is screwed into the channel 14 becomes. The channel 14 is limited on the one hand by the Inner wall of the outer C-profile and here in particular the supernatant 5b on the outer leg 5a of the C's inward points and the outer edge of the flange-like projection 4b of the Leg 4a of the U-shaped first part 4, which in the C-shaped Part 5 is inserted.

The clamping screw 8 is according to the invention, for example a conventional screw, but it has the hereby Task to stretch the two parts 4 and 5 apart, since the dimension of the screw in relation to the channel dimensions are designed so that a longitudinal movement of the bolt profile 1a takes place on the post 1, whereby the latch 1a the post 1 is pressed.

Therefore, this invention not only achieves a torsion resistant Connecting or stiffening the latch profile 1a on Post 1, but at the same time a gap-free assembly, as desired, the bolt 1a on the post 1.

The arrangement is chosen so that two channels 14 at the respective legs 4a, 5a of the part 4 and 5, respectively result.

In a further variant of the invention is provided that the fastening profile 2a, which horizontally oriented is threaded, also bolted to the stiffener. For this purpose, in the second part 5 channel-like openings 8a provided, in which corresponding fastening screws 7 for attaching the fastening profile 2a are screwed. The Openings 8a are channel-like and at a Extrusion process for the production of the second part 5 easily to incorporate. The arrangement of the openings 8a is in particular advantageous as the load on the mounting profile 2a, introduced directly into the stiffening and in the second part 5, the first part 4, directly in the post 1 is transferred.

A further variant of the invention is shown in FIG which the fastening profile 2, which runs vertically, a recess 9 has, in which a profile projection 10 of the horizontally extending fastening profiles 2a stands. This profile projection 10 is provided with a screw 11 in the Post 2 screwed. Again, there is a load dissipation of the profile 2a directly into the post 1. According to the invention provided that both variants can be combined.

In Fig. 3, the principle of kinematic reversal is particular shown in the arrangement of parts 4 and 5. The C-shaped, larger part 5 is not in this variant on the bolt 1a, but on the post 1 with appropriate mounting screws 6a attached. The small first part 4 is in the recess 9 attached to the front of the latch 1a. Form in the same way again the channels 14, in which the clamping screws. 8 are rotatable. In this case then lie the openings 8a with respect to the bar profile not inside but outside.

This kinematic reversal of Fig. 3 is the same can also be combined with the proposal of a profile supernatant 10, this is shown in FIG. 4.

Another advantage of the invention is that in the workshop-side preparation of the facade assembly of the both parts 4 and 5 is prepared, which achieves that the relative positioning of bar 1a and post 1 is set equal workshop. This is simply the Length of parts 4 and 5 selected according to the depth of the bolt. This ensures that the latch 1a with respect pinned in the right place, so a smooth, internal surface of wood results, which is gap-free.

In general, the part 4 and the part 5 are carried out in this way, that a Verpressmöglichkeit such that no Gap formed between post 1 and latch 1a. this will by appropriate pre and residues on the parts 4 and 5 generally achieved, but it is also possible to appropriate Wedge constructions to be chosen with inclined planes at the Share 4, 5 interact and so compressing the Bolt and the post at the junction result.

According to Fig. 5 is a stiffener for a mullion and transom construction presented in a more compact design. The depth of the Parts 4, 5 is compared to the embodiment of FIGS. 1 to 4 much lower, the arrangement is in this case, however identical to the previously described embodiments. The two U-shaped parts 4, 5, at the legs at right angles formed projections 4 a, 5 a are formed form, as well previously described, the channel 14, in the one for bracing Both parts provided clamping element 15 can be inserted. at this clamping element 15 are screws, pins, Wedges and the like, which will be described later. Also in this embodiment of the invention, the two parts 4, 5 interchangeable, so that part 4 in the recess in the bolt and part 5 are to be fastened to the outside of the post 1. Due to this compact design, the edge of the recess is relatively low, that is, he can have a greater power pick up and the risk of chipping is at this point of the bolt substantially reduced.

FIGS. 6 to 8 show three variants of a connection between post 1 and latch 1a shown. After Fig. 6 is the first part 4 receiving second part 5 on the side wall a post 1 attached. By means of screws 6 takes place the attachment. By a sliding movement of the Bar 1a, in the recess part 4 is fixed to the Part 5 inserted so that their supernatants 4b, 5b with each other in Intervention can be brought. A stop 29 on part 4 prevents that the latch 1a pushed out too far over part 5 is, so that its position relative to the post 1 aligned is. This stop 29 consists of one, advantageously molded or punched from a sheet metal component with a screw 6b on the latch 1a can be fastened. This stop 29 is also like the first part 4 in the recess 9 of Riegels 1a sunk. After nesting of both parts 4, 5 together, the front edge of the recess 9 of the Riegelels 1a flush to the side wall of the post 1 at. through the clamping elements 15 are both parts 4, 5 with each other braced. The attachment profile 2a is by means of additional Screws (not shown) attached to the latch 1a. At this fastening element can now be attached to the facade element with the stiffener acting on them Torque in the post 1 derived.

According to Fig. 7, the fastening profile 2a is also by means of Clamping elements 15 on the stiffener and by another Screws (not shown) attached to the latch 1a. By this variant of the invention is achieved that of the Mounting profile 2a recorded load of the facade element (at least partially) directly over the clamping elements 15 in the introduced for the parts 4, 5 stiffening formed and so in the post 1 is removed.

In Fig. 8, an embodiment of the invention is shown in the combination of a stiffening means of the parts 4, 5 and a stiffening means of a profile projection 10 shown is. Again, the clamping elements 15 are used for attachment the fastening profile 2a with the stiffener, wherein In addition, the profile projection 10 in a recess 12 in Mounting profile 2a of the post 1 engages. In this way the load is over the first (through the parts 4, 5) and over the second reinforcement (profile projection 10 in recess 12) derived on the post 1. This variant according to the invention, as described and shown in Fig. 8, achieved that even higher loads on facade elements in the inventive Post-and-beam facades are absorbed and diverted can. Part of the load is passing through the parts 4, 5 formed stiffening introduced in the posts 1, another Part of the load is via positive or positive interaction the profile supernatant 10 in the recess 12 in the perpendicular profile 2 initiated. This works Profile 2 with to carry the load picked up by the latch 1a becomes.

Fig. 9 is a side view and a bottom view consisting from the parts 4, 5, shown. The one by the supernatants and leg-shaped channel 14 points in the region of Channel 18b has a narrowing 16. This narrowing 16 will by a deformation 19 of the supernatant 4b of the male first part 4 formed. This deformation 19 extends only over a partial region of the supernatant 4b.

FIG. 9 shows an embodiment of the invention, in which only one deformation 19 on the supernatant 4b is provided. The 19 caused by this deformation constriction 16 of the channel 14 is in the region of the channel end 18b. In the channel 14, the clamping element 15 is inserted. This Clamping element 15 consists of a smooth pin portion 21 and a thread 23 having area 22. The thread 23rd cuts into the material of the channel boundary. The Length of the pin is chosen such that first the thread 23rd engages the channel boundary before the tip 24a of the pin-shaped portion 21 enters the region of the constriction 16. By further screwing the pin comes the pointed tapered tip 24a of the pin in the constriction 16 and clamped the two parts 4, 5 with each other. By the deformation 19 causes the channel 14 to narrow in one direction only while the diameter is the same in the other direction remains wide. In this way it is caused that not the Legs of the U-shaped parts 4, 5 unfolded, but only the supernatants are moved away from each other. To this It is achieved that part 4 is further pressed into part 5 is, with which the latch 1a against the side wall of the post. 1 is pulled. Between side wall of the post 1 and front side of the bolt 1a thus becomes a possibly existing gap reduced. The screw head 24b prevents too far Screwing the clamping element in the channel 14 or has the Function, the fastening profile 2a when attached by means of To fix clamping element 15 to the stiffener.

According to FIGS. 10a to 10d, the further embodiment of a Clamping element 15 for clamping the parts 4, 5 with each other shown. This clamping element consists of a bracket 25, consisting of two mutually substantially parallel Pins 26 consists. Both pins are at one end with each other connected. Advantageously, the bracket 25 is made bent a wire. The bracket 25 is with its pins 26 in the channels 14 of the stiffener insertable. Not after one illustrated embodiment, the straight pins 16 act the bracket 25 with the constriction 16 bracing together, so that a longitudinal movement of the two parts 4, 5 avoided each other becomes.

According to the illustrated embodiment of the invention, the Pins 26, a bend 27 which is connected to the constriction 16 of the Channel 14 interact and so the two parts 4, 5 against each other fix.

In Fig. 10b an embodiment is shown, in which see how the bend 27 with the constriction 16 in the channel 14th interacts.

Compared to the previously illustrated embodiments, in which the clamping element 15 is then inserted into the channel is when both parts 4, 5 already engaged are brought, according to this embodiment, the first Bracket 25 in the angle range between leg 5a and supernatant 5b inserted and then part 4 in part 5 inserted. When the bend 27 and constriction 16 toward each other come lie, sets the clamping action of the clamping element 15th one.

To fix the position of the bracket 25 relative to the part 5, is provided, the bracket 25 in the area in which the two pins 26 are interconnected to make wider than the clear width between the legs 5a of the part 5, so that the Bracket 25 does not slip too far in part 5. On the other end the pins 26 on bent ends 28, which slip of the bracket 25 in the other direction also prevent. The fact that the two pins 26 against each other are elastic, the bracket 25 can be easily used in Part 5 become. When pulling out the part 4 of Part 5 remains the Bracket 25 by the broadening and bent ends 28 in Part 5 fixed so that with this bracket 25 a simple releasable Connection between the parts is created.

11, an embodiment of a stiffener is shown, at the part 4 to be picked up by the second part 5 consists of two sub-elements 30. These two sub-elements 30th are also in cross section, as the originally shown Part 4, T-shaped, wherein the crossbar of the T's of part 5 is added. Again, between the Transverse web of the T and the supernatants 5 b formed a channel, the is widened with the clamping screws. Two or more such sub-elements 30 can be used to form the stiffening on Post 1 may be provided. Again, it is possible both To interchange parts with each other, so that the elements 30 am Bar 1a and part 5 is fixed to the post 1. At a not shown version of the part 4 receiving part 5, part 5 may also be formed multi-element, so that the parts are associated with the parts 30. On This way is an even easier and easier way formed to form a stiffener.
