Description

The invention is directed to a device for clamping surface elements on the edge, preferably glass panes for the construction of greenhouses, winter gardens or other parts of the building provided with glazing, with at least one cross-sectionally substantially T-shaped first profile element, the T-bar of which is used as a clamping web for the holder the surface elements and its T-web are designed as a fixing web protruding from the end face of the respective surface element and with a sawtooth catch and with a second profile element designed as a cover profile with an inner recess with additional clamping webs opposite the clamping webs of the first profile element in the position of use and with fixing elements for fixing to the Sawtooth rasterization of the first profile element, the first profile element being formed by an outer plastic profile which is T-shaped in cross section and an inner metal profile which is also essentially T-shaped in cross section is.

Such a device is known for example from DE-C-2 808 155. There, for retrofitting existing support structures for greenhouses, the respective T-metal profile is retrofitted with a plastic jacket element that can be clamped over it and has saw teeth on the central web. After inserting the glass panes or wall elements, a cover strip is slipped on, which is equipped with sloping legs, one free end of which lies on the pane, while the other free end snaps into the saw toothing.

In this known solution, the metal profile is only partially covered with plastic.

The object of the invention is to provide a solution in which, in particular, the static loads occurring, but also the tightness and strength, while maintaining a light profile shape and adequate heat protection and avoiding cold bridges, are not only taken over by a metal profile, but also at least partially by one Plastic profile.

This object is achieved according to the invention in that the plastic profile is designed as a hollow box-shaped profile enclosing a cavity in the T-head area and the metal profile introduced therein as a rolled sheet metal profile which has an internal recess in the T-head area or is hollow.

With the invention it is achieved that a statically stable plastic hollow profile is provided, in which a likewise statically favorable metal profile is inserted.

A solution according to DE-A-1 943 513 relates to the frame of a window. Such frames do not inherently perform any static or constructive functions for the elements in which they are installed.

In an embodiment, the invention provides that the T-web of the metal profile is formed in two layers.

Another possibility of reinforcing the profile is taken into account by the fact that the hollow profile area of the metal profile is approximately trapezoidal in cross section.

The invention is explained below with reference to the drawing, for example. This shows in

• Figure 1 is a simplified, perspective view of a greenhouse as an application example for the invention.
• Fig. 2 is an enlarged sectional view along line 11-11 in Fig. 1 and in the
• 3-6 further, modified exemplary embodiments of the invention in the representation according to FIG. 2.

The greenhouse 1 shown in FIG. 1 consists of a multiplicity of glass panes 2 which are connected at the edges with the device 3 according to the invention to form the overall greenhouse 1.

2 shows a section through the device 3 of an embodiment variant. In the example shown, the device 3 consists of two profile elements, namely a first profile element 4 which is essentially T-shaped in cross section and a second profile element 5 which is C-shaped in cross section in the example shown.

The first profile element 4 has an internal metal or steel reinforcement 6, which e.g. is formed from a rolled sheet metal profile. This steel reinforcement 6 itself is essentially of a T-shaped cross section, a hollow, approximately trapezoidal T-head 7 being formed, with the shorter side to the T-center web 8. This is designed in two layers, one layer 9 being shorter than the other Location is 10. The longer area of the layer 10 is crimped or flanged or rolled over the free end of the layer 8, as can be seen in FIG. 2. The reinforcement profile 6 thus maintains a high degree of inherent rigidity and bending or the like is prevented.

This reinforcement profile 6 is encapsulated by a plastic profile 11, which is also T-shaped in cross section. In the example shown, the T-head region 12 is approximately rectangular in cross section. The T-web 13 starting from the head region 12 is hollow and surrounds the T-web 8 of the reinforcing profile 6. In the same orientation as that of the T-web 13, clamping or edge webs 14 are injection-molded onto the head region 12, which are clamped when a pane 2 is clamped or 2 'lie against them and form a drainage channel 15 with the central web 13 for the outflow of condensation or rainwater.

The T-web 13 is designed as a fixing web, ie the second profile element 5 is fixed to it with a clamping interposition of glass panes 2 or 2 '. For this purpose, the T-center web is equipped on both sides with a sawtooth grid 16 into which the sawtooth side flanks 17 of the second profile element 5 can engage.

This second profile element 5 carries these sawtooth side flanks 17 on the inside, i.e. it overlaps the fixing web 13 on both sides with these fixing elements 17 for engaging in the corresponding grid on the fixing web 13.

In the exemplary embodiment according to FIG. 2, the second profile element has at least two clamping webs 18 on both sides, which either serve to rest against the pane 2 to be clamped in or from z. B. door rail profiles 19 or other cover profiles can be accessed. These clamping webs 18 can also be designed as separate components, if corresponding dovetail guides or undercuts or the like are introduced into the body of the profile 5 and these clamping webs can then be drawn in there as rubber strips or the like (FIG. 3). A slightly different hatching indicates that the second profile element 5 can be equipped in one piece on the edge side with sealing lips 20, which can rest on the pane 2 or edge profiles 19, as shown.

As can be seen from FIG. 2, the assembly of panes and thus the assembly of entire greenhouses 1 is particularly simple, regardless of how thick the panes are. Two disk thicknesses are shown in FIG. 1, a thicker disk 2 and a thinner disk 2 '. The disks are placed on the profile 4, the edge webs 14 forming the clamping webs of the first profile element 4. When the disks are in place, only the second profile element 5 is pressed on and snaps in according to the sawtooth pattern according to a certain path when the second clamping web 18 rests on the outer surface of the disk 2 or 2 '. The sealing lip 20 is already in contact with the outer surface of the clamped disc. Obviously, additional assembly aids are not necessary, in particular any screw connection is unnecessary. Disassembly is also very easy. It only requires the intervention of a corresponding tool in the central cavity 21 of the second profile element 5 in order to spread the sawtooth side flanks 17 a little so that they come out of engagement with the sawtooth grid 16 on the first profile element 4.

4-5 further exemplary embodiments of the device 3 are shown. For better readability, the reference numerals are deleted (Fig. 4), twice (Fig. 5) and triple (Fig. 6) insofar as they refer to components that correspond to the exemplary embodiments according to FIGS. 2 and 3. Elements not mentioned there are given new reference numerals.

In an exemplary embodiment according to FIG. 4, the sealing lips 20 'are designed as separate rubber profile elements which are inserted into clamping grooves. In the example shown there, the clamping web 14 'on the first profile element 4' also has a seal. The reinforcement profile 6 'is designed there in cross-section as an open trapezoid in the head region in order to enable the design of a T-groove 22 into which, for example, assembly elements can engage, as is shown in FIG.

In an exemplary embodiment according to FIG. 5, a design is shown which corresponds approximately to the left half of the figure in FIG. 3, where a separate seal or a cover strip 20 "is again inserted into grooves on the second profile element 5".

Finally, the exemplary embodiment according to FIG. 6 has a design in which the second profile element 5 "'is also designed as a hollow chamber profile. The profile of the rubber seals 20"' shown there, also as a partial hollow chamber profile with special sealing webs, is particularly suitable for residential construction suitable.

Of course, the described embodiment of the invention can be modified in many ways. For example, another profile of the T-head 7 is shown in broken lines in FIG. the metal reinforcement can also be profiled differently. Of course, it is also possible to provide arch shapes, rectangles, squares or combined profile shapes instead of the trapezoidal shape of the head.
