In such Profiles result in difficulties when the sight glasses of the two profiles joined together in the overlap should run essentially parallel, what from Degree of strength if it is absolutely necessary «,

There are already clamping connections for an overlap of such profiles, in which segments have an inner flange inserted into the hook of the adjacent profile and an outer flange that extends over the inserted flange of the adjacent profile with their webs essentially parallel, so that the visual axes of the two profiles are essentially parallel. In the area of the overlap, the known clamping connections of this type use brackets that hold the profiles together "possibly also by means of a clamping screw", which are intended to prevent the overlap from opening up when the two profiles are pushed in and then the The necessary cohesion of the overlap is more guaranteed. According to known embodiments, these brackets encompass both profiles at one end of the overlap and accordingly lie on the outer faces of the profiles, but only touch the inner flanges on their outwardly directed edges.

Me known, close-fitting clamping connections are, inaessen not free of specialist parts »In particular, they do not allow tilting of the" two extension profiles. For this, it must be taken into account that the "two extension profiles are only placed on top of one another with the relatively narrow edges of two of their flanges and that the" known BiIgI also only rest against the edges of the flanges at this point. Pole-wise, there is a slight tilting of the two profiles in such a way that their axes of gravity are no longer parallel to one another, but rather form an "angle". As a result, the durability and the ability to be sewn into place in a superstructure bracket made up of segments are considerably reduced, and the brackets are also loosened, which can lead to the frames collapsing.

Such inserts, however, change the tensioning pressure in a disadvantageous way: and also represent additional components which, under certain circumstances, make the tensioning connection considerably more expensive and complicated.

In addition, the control can be practically implemented in various ways . So Each preferred embodiment is already the arrangement of the clamping screw within the Sehellen "arbitrary. Of!

It is known that in the course of the insertion process of swei connected to one another within an overlap in a pressure-resilient manner The extension frame is used by the bracket from the Segeaent be taken along * where they have their largest contact surface own. If the length of the overlap in the course of the insertion of the extension frame segments connected to one another suniraat, it can then happen that one or "both Hangers left behind and then the risk of impaling the overlap occurs. It is known for this on the temples To attach drivers »which are in front of the face of a of the profiles and thereby be taken along by this ", Laugh the! Price increases are the parts of the gate of such a pressure drop Clamping connection realized ^ that the ELsnsehlasche one of the two clamps forming the clamps has a cuff-like extension, the edge region of which Clasps like the Außenflanseh and in front of it the end face of the associated profile laying driver nose ends.

The technical gate parts that can be achieved by the inflation exist especially in the fact that a completely tilt-proof pressure-friendly clamping connection is created that

see from the sections of commercially available rolled profiles, namely from Plaeheisen and! E-Profiles "can be produced and is therefore comparatively" cheap. This pressure-resilient © tensioning connection also has an essential door pull that it also reliably maintains its predetermined position in the overlap in the course of inserting the extension profiles, so that sie. Loc & eruagen or can not result in three turns of the expansion profiles. It is therefore possible for the control system to orient and maintain the axis of the shafts of the profiles in such a way that the expansion frame made from them can develop its maximum resistance.

The detailsι other features and advantages of the control result from the following description of a preferred, however, an exemplary embodiment of the subject matter the! price increase based on the figures in the drawings! show it

In the figures, a drue & aaehgiehige spam connection for expansion frame segments is shown in accordance with the embodiment shown! -Profile. In detail, one recognizes from fig. 1 "that the pressure-yielding tension connection is used in the sabiaen of an overlap of the two extension profiles designated 1 and 2 ".

At the ends of the overlap , brackets are provided that can be tightened with two tensioning screws each and are generally designated by 3 and 4 in FIG. 1, as shown in FIG.

The Bi | pl 3 bsw. 4 are each made up of two bells »von deaen the two sehellen of the bracket 3 in fig. 2 are denoted by 31 and 322. Each clamp consists of a flat joint lying on the outer flange 22 or 12, which in
