Abstract

The invention relates to a post- and horizontal tie-connection for a frame construction, in particular for windows, doors, facades and the like. For this the horizontal ties are mounted in a post opening (27) of the vertical post (1). The post-opening (27) in the region of a respective tie connection position has a prefabricated sealing section insert (28) which is adapted in the assembled position of the tie to grip around the latter partly in tight abutment therewith, which insert is releasably fixed in the post- opening. Preferably the U-shaped seal section insert (28) is so formed, that it can be pressed in by hand into the post opening and engaged with corresponding shaped sections of the post cross section. Further to secure good sealing and effective compensation for expansion in the region of the junctions, the seal section insert (28) is preferably made of rubber or other elastic material. To secure the tie (2) in post (1) there may additionally be provided a fastening member (42) which is slidable in a longitudinal groove (43) of the tie. <IMAGE>

Description

SPECIFICATION Connection of a tie to a post of a frame construction The invention relates to a connection of a tie to a post of a frame construction, in particular for windows, doors, facade- and indoor-swimming-pool constructions and the like, in which the tie with its front end engages into an opening of the connection-post embracing and regionally spaced from the circumference of the tie, and is held in the latter sealed against the post, with fillings such as panes, panels or the like, being fitted in frame fields formed between the posts and the ties.

A tie connection of this type is known from DE-PS 29 16 800 of the applicant. In order to achieve effective sealing in the region of abutment between the vertical posts and the horizontal ties, which further allows sufficient compensation for expansion between the posts and the ties, the known construction provides that the individual post cross sections are each provided with two longitudinal grooves lying spaced one behind the other for the reception and guidance of sealing strips.

The first longitudinal groove here serves for the guidance of the sealing strip outside the respective tie-junction, whereas the second longitudinal groove receives the sealing strip in the region of the junction, so that it can be guided continuously, and without overlapping the tie sealing strips which run at right angles thereto projecting into the post, about the outer contours of the tie sections and back into its original position in the first longitudinal groove.

In this situation the sealing strip is guided and supported in the second groove for the total height of the displaced region in the post cross section, and with its sealing lips closely abuts the external contours of the tie, so that effective sealing is ensured between posts and ties at the junctions.

With respect to their sealing function at the junctions such connections have proved themselves in practice. However it has turned out that threading in the continuous sealing strips into the seal reception grooves which lie behind one another in the region of the junctions is relatively inconvenient, because due to their great elasticity the seal cross sections normally change their cross-sectional shape in the region of their right angled bends when guided around the outer edges of the tie, which impairs the optical appearance of the seal connection. Further sometimes this makes it necessary for two seal strips which cross one another between the post and the tie to be stuck together where they touch, in order to achieve a clean transition in the region of the point of diversion.

The invention is based on the object of providing a constructionally compact seal arrangement between tie and post which can easily be assembled.

Starting from a frame construction of the above mentioned kind, this is achieved according to the invention in that, the postopening in the region of a respective tie connection position has a prefabricated sealing section insert which in the assembled position of the tie grips around the latter regionally in tight abutment therewith, which insert is releasably fixed in the post-opening.

According to a second aspect of the invention there is provided a connection for use in assembling a frame construction in which one or more ties engages with its front end into an opening of a post, said connection comprising a prefabricated sealing section insert adapted in the assembled position of the frame to be releasably fixed in the post opening and to grip around the tie regionally in tight abutment therewith.

In this manner it is possible to let the panel seals of the posts and the ties run towards each other without diversions.

The sealing effect on the outer surfaces of the tie is exclusively provided by the seal section insert onto which the ends of the panel sealing sections of the post or tie respectively abut bluntly in the region of the junction. Due to the tight abutment of the sealing section both in the post as well as on the tie circumference effective sealing is ensured.

Suitably the seal section insert has a Ushaped cross section and has on both sides of its shank exterior surfaces projecting retaining shoulders or the like which engage into longitudinal hollow spaces of the post. These retaining shoulders serve in the first line for fixing the sealing section insert in the post in a manner which makes for easy assembly.

Preferably the retaining shoulders have positioning surfaces running obliquely to the longitudinal central plane of post. Suitably the positioning surfaces end on the outer edges of the retaining shoulders.

By the manner of making the retaining shoulders in accordance with the invention it is easily possible to push the sealing section inserts into the openings in the post by hand.

As a further development of the subject of the invention the shank ends of the seal section insert have contoured cut outs, which correspond in their contours to the seal reception cross sections for the fillings and which in the assembled position of the seal section insert in the post-opening form continuations of the seal reception cross sections.

In this manner it is possible to let the ends of the panel seals in the region of the post opening run into the shank cut outs of the sealing section insert, so that with their front ends they abut immediately on the respective outer surfaces of the tie and thus ensure an unbroken sealing effect right up to the outer surface of the tie.

Suitably along the exterior of the basis of the U-section there extends a shaped web, having an undercut along its whole length, which can be engaged in a corresponding shaped web in the longitudinal hollow space of the post. Preferably, the shaped web extends beyond the length of the basis and with its ends extending beyond the basis merges into the retaining shoulders on either sides of the shanks. In this manner the engagement of the sealing section insert in the post which is in any case secure and firm is still further stabilised.

To faciliate pressing in or engaging the seal section insert in the post opening according to a further characteristic of the invention it is suggested that the front end of the seal section insert facing the longitudinal central plane of the post has bevelled positioning surfaces.

Additionally it may be provided that the positioning surfaces are formed in web tongues projecting forward in the longitudinal direction of the seal section insert from its front edges.

The seal section insert is suitably made of an elastic material, for example rubber. The exterior contour of the seal section insert advantageously substantially corresponds to the contour of the post opening. Preferably the retaining shoulders are narrower than the breadth of the seal section insert. For additional fastening the seal section insert may be screwed to the post.

According to a particularly inventive characteristic there is provided that, the tie has a fastening member which is slidable in a iongitudinal groove, and which in its assembled position has an end which projects beyond the front face of the tie and engages in a cut out formed in the post. Such a fastener forms the only securement of the tie to the post.

Additional screw connections between the post and the tie are not necessary, as the total retention of each tie in the longitudinal and transverse direction relative to the post is taken up by the shanks and basis portion of the section insert and in the direction of suction solely by the fastening member, which on one side is guided in the cut out in the post cross section and on the other in a contoured shape of the tie.

Preferably the fastener has a rectangular cross section. Suitably the front end of the tie in its assembled position ends up spaced from the interior wall of the post opposite it. In this manner there is sufficient compensation for expansion not only in the transverse direction of the tie via the elastic insert piece, but beyond this also in the longitudinal direction of the tie.

Whereas it is usual for the posts to be vertical and the ties to be horizontal, and the posts to support the framework as a whole the use of embodiments of the invention is not limited to such a situation. The posts could run horizontally and the ties vertically, or they could both be angled.

The invention is hereinafter described with reference to an embodiment shown in the drawings.

In the drawings there is shown in: Figure 1 a frame construction with vertical posts and ties connected thereto in the region of the junctions, Figure 2: a junction cut out A of the frame construction of Fig. 1, in a perspective view.

Figure 3: a longitudinally split post with an assembled seal section insert prior to insertion of the tie, in perspective view, Figure 4: front, side and top views of a seal section insert Figure 5: a sectional view on line V-V of Fig. 1, Figure 6: a view of the junction A of Fig. 1 on an enlarged scale, Figure 7: a cross section on line VII-VII of Fig. 6.

In the embodiment shown in the drawings the vertical posts of a facade curtain wall are indicated by 1 and the horizontal ties which run at right angles thereto by 2. The frame fields defined by the posts and ties are filled with panes 3. Instead of these any other desired filling elements could be inserted. In the following description and in the drawings the vertical posts 1 form static sections. As a variation on this it is also possible for the horizontal ties to take over the static function.

In such a case the ties 2 are made greater than the posts 1. The suggestion according to the invention can be applied in both cases in a suitable manner.

As can be seen in Fig. 2, which shows the cut out "A" of Fig. 1 in the region of a junction between the post 1 and the tie 2, each of the posts 1 consists of two partial sections 4,5 of which the partial section 5 comprises a section cross section 6 and a cover strip 7. The partial section 4 is heat insulated against the partial section 5 arranged on the outside of post 1 by means of an insulating web 8. The partial section 6 abuts via seals 9 on the edges 3' of the panes and is screwed to partial section 4 at 10.

In the region, in which the edges 3' of the panes 3 engage in the posts 1, the latter have on both sides of the insulating webs 8 a spacing gap running along their length which is laterally bordered by abutment webs 11, 12 respectively and the partial section 6.

The abutment webs 11 12 have continuous longitudinal grooves 13,14 for reception of sealing strips 15,16 respectively.

The horizontal ties 2 are constructed in a similar manner. The interior partial section is indicated by reference numeral 17, the insulating webs by 18 and the external partial section by 19 and the cover strip by 20. The abutment webs 21,22 of tie 2 also have longitudinal grooves 23,24 in which sealing strips 25,26 are received.

The post 1 in the region of the junction has a U-shaped cut out 27 which hereinafter is called the post opening. It has such a height and depth that each tie 2 can with its front end project a short distance into opening 27.

Opening 27 was cut out of the abutment webs 11,12 including the longitudinal grooves 13,14. The post openings 27 are located everywhere in the region of a junction where a tie is to be received in a post. Its cross section is larger than the circumference of the tie by a determined amount.

In accordance with the invention an elastic sealing section insert 28 is inserted into each post opening 27, which insert is so formed that in the assembled position it grips in tight abutment around the end of the tie running into post 1, the front end of which tie terminates at a distance from the insulating webs 8. The sealing section insert 28 consists for example of an elastic rubber, and has a Ushaped contour adapted to the post opening 27 and is removably engageable in the post opening, but can additionally be screwed in. It has on each side of its shanks 29,30 outwardly projecting retaining shoulders 31,32 as well as positioning surfaces 33,34 running obliquely to the longitudinal central plane of the post 1 which surfaces end at the outer edges of the retaining shoulders 31,32 respectively.

The shank ends of the seal section insert 28 have contoured cut outs 35,36 whose contour corresponds to the cross section of longitudinal grooves 13,14, so that with the sealing section insert in the assembled position the cut outs 35,36 coincide with the longitudinal grooves 13,14 and together form a through channel for reception of seal strips 15,16.

Along the exterior of the basis 37 of the sealing section insert there projects from the back of the basis a shaped web 38 integrally formed therewith and having an undercut 38' (Fig. 4), which in the assembled position engages with a corresponding groove 39 which is provided behind and spaced from the longitudinal groove 13 of post 1. The shaped web 38 extends beyond the length of the basis 37 of the sealing section insert, and on each side merges into retaining shoulders 31,32. In order further to facilitate assembly of the sealing section insert, the front ends of the seal section insert facing the longitudinal central plane have bevelled positioning surfaces 40, which are formed in web tongues 41 of shanks 29,30 which tongues project therefrom in the longitudinal direction;.

A fastening member 42 serves to fasten each tie 2 in the post opening 27, which member is guided in a longitudinal groove 43 of the tie. In the assembled position it projects with its protruding front end into a cut out 44 and is thus guided on one side by cut out 44 and the other side in the longitudinal groove 43 of tie 2. If in a frame construction there is a tie 2 abutting each side post 1, (Figs. 5, 6, 7) then the fastening member 42 is pushed so far through the cut out 44 of an intermediate section 44' until it engages on the other side of post 1 in a longitudinal groove 43' of the connecting tie 2. In addition the fastening member is secured by means of a worm screw 45.

For assembly of the sealing section insert 28, the latter is pressed with its front face having the web tongues 41 foremost into into the post opening 27 in arrow direction 46, until retaining shoulders 31,32 after sliding along positiioning surfaces 40 engage into the abutment edge of the post opening 27 in a guiding groove 47 forming a longitudinal hollow space along the interior wall of the abutment webs 11. During this movement the positioning surfaces 34 simultaneously support themselves on the corresponding cut out edge of the post opening 27. After engagement the shaped web 38 also takes its resting position in the groove 39 of the guiding groove 47.

Subsequently the tie 2 while leaving a gap between its front face and the insulating webs 8 is pushed into the sealing section insert 28 and post 1. This final fixing is carried out, in that the groove 43 guiding the fastening member 42 is pushed into the cut out 44 of the intermediate section 44' and secured by a screw 45. Subsequently there take place mounting of the panes 3, insertion of the sealing strips 15,16 respectively 25,26 and the mounting of the cover strip 5.
