Abstract

Design of an insulating panel which, in addition to its heat-insulating and cold-insulating property, in particular ensures a high degree of light transmission and, from the point of view of the practical application, makes possible problem-free installation by virtue of a profiled and compacted configuration of the panel periphery. It is characterised in that it consists of a largely light-transmissible capillary-structured core of low density with transparent cover layers on both sides and has on its circumference a profiled peripheral structure of higher density.

Description

The present invention relates to the configuration of a insulating plate, which in addition to its warm and cold insulating property especially high light transmission ge guarantees and application technology through a profiled and compacted plate circumference shaping a problem-free Assembly enables.

There are panels with heat and cold insulation properties as is known in the form of insulation boards in the construction industry, e.g. out Plastic foams, mineral wool or glass fiber mats. Such panels have high quality insulation properties, but are opaque.

Translucent or transparent insulation panels are up to now less in use in the market, their insulation effect is less. If you want to increase it, this works Cost of transparency, the passage of light becomes worse. Examples include the double-wall sheets or the Polymethacrylate foams.

So far, the capillary-structured plate has developed here transparent plastics best proven, their light Passage due to the capillary arrangement (lower axial direction right to the plate surface) with increasing plate thickness and thus increasing insulation effect only slightly goes. However, such plates are mainly used in relatively small thickness with double-sided glass cover used as double glazing.

The use of capillary structured plates for use areas that have the high insulation values of today's known light Requiring impermeable panels requires other constructions modes of operation. The plates must have a suitable shape easy and secure connection options to Nach ensure bar constructions. Are the neighboring construction tion e.g. other insulation materials (such as rock wool, glass wool, Plastic foams), the capillary plates must be light and be as stiff as possible and have the same thickness dimensions exhibit. At the same time, simple assembly must be possible be given.

The present invention solves this problem by a gan ze set of shapes that the advantageous application of such highly insulating translucent capillary allow plates.

Above all, it takes into account the possible combinations commercially available insulating plates, so that e.g. in industrial halls construction in a surface made of foam sheet laid under a roof th light strips can be inserted, with the same or approximately the same insulation for illuminating the interior of the building contribute. Safe and simple installation is essential possibility that also a lightweight construction of the Requires capillary plates.

In the present patent application such Lö solution options described.

Starting from a capillary produced in series production plate which e.g. of thermoplastic plastic capillaries made of polyethylene terephthalate, polycarbonate, polymethacrylate or polystyrene is formed and the top of the plate areas at the tube ends of the capillaries through cover layer ten are completed, this capillary plate is attached to their Scope made a change in shape, once by density increase the intercapillary space (between the capillaries) closes at the plate circumference and thus at the same time geo receives metric form for follow-up to bar plates, neighboring profiles or end constructions are suitable.  

The plate then has a more or less on its border niger non-translucent structure and has Ver seal the structure receive mechanical strengthening.

The main feature of the present invention is the design an insulating plate made from a largely light permeable capillary structured core with low density transparent cover layers on both sides and on their Perimeter a profiled border structure of greater density having.

The profiled border ensures that described above connection options to neighboring constructions. she will preferably by thermal melting processes on the plate start generated.

But also the pouring or sticking of e.g. thermosetting Material or the attachment of metallic or nonme metallic profiles on the plate circumference can be such a pro Form filleted border.

Another special feature of the present invention is the additional gain of those described so far Capillary plate types on their borders.

This has the advantage of another mechanical edge reinforcement in the connection area to neighboring constructions, however also for the plate itself with regard to handling or also lower transport risks (it represents the capillary plate It also represents "packaging", so to speak).

On the other hand, it can be done with extended design options on the outer edge advantageous to facilitate assembly wear.

The transition from the capillary plate edge to the edge reinforcement is advantageous to form as a positive connection. By the proposed in the present patent application This is easy to implement. Doing the reinforcement on the plate side is one of the circumferential shape of the plate to have the appropriate profile design.  

Accordingly, such a plate is characterized in that the reinforcement border is compatible with the panel side for plate edging and compatible shape on the circumference tion to neighboring structures.

In particular, the reinforcement border can be made from an art consist of foam.

The addition of a circumferential shape to the capillary plate such plastic foam can be made by directly foaming the Remove material with simultaneous shaping in one tool.

It is also possible to have a frame made of reinforcing material to form and place this around the capillary plate. A such a frame can in turn be made from a whole molded part stand or be assembled from several individual strips, their profiling e.g. can also be done by milling can.

Finally, it is possible that the area between plat circumference and border reinforcement, if sealed should be mutually provided with a sealing material is.

Here a positive connection between plat te and reinforcement very advantageous. You can use it to or save welding processes.

The profile-like formation of the capillary plate edge he also allows the enclosure of two or more, with Individual plates spaced from each other by the order edge reinforcement. The single plate package can do this preferably get the same thickness of the edge reinforcement.

The following figures show examples of different types design options of the plate according to the invention. For the sake of clarity, the drawings are to scale shown distorted. The outlined solution possible speeds apply to thermal deformation of the plate edge. which is filled in homogeneously black here, really However, there are differences in density in the forming zone.  

FIG. 1a shows the cross section of a capillary plate with double-sided transparent cover layer in the form of a thin film.

The capillaries 1 stand with their axial directions perpendicular to the plate surface 2 , which is covered with the film 3. The film here protrudes somewhat beyond the plate surface, this for the further molding process on the plate circumference according to FIG. 1b.

Fig. 1b shows a plate as it is written in Fig. 1a be, after making a change in shape on the plates. Here, only the cover foils are folded over from the top and bottom of the panel and welded together in a sealing manner. The profiled circumferential structure represents the simplest option for a compacted plate border with a rectangular profile.

The picture shows a cross section across the plate width. At the same process is carried out on the longitudinal plate ends, with the protruding film at the corners of the panels or received clippings.

Fig. 2 shows another possibility of changing the shape of the plate circumference. Using thermoplastic material for capillaries and cover layers, the reshaping (profiling and compression) has been carried out at the edge of the plate by melting processes, which has also covered areas of the capillary structure at the edge of the plate. It is not absolutely necessary to fold over the protruding film according to FIG. 1b, since the entire edge zone is compressed.

Fig. 3 shows a different shape of the plate edge.

Fig. 3a shows the original plate represents a cross-section through the plate width. Their cover layers 3 only extend to the extent of the final plate surface, as is the case after the edge deformation. (The same also applies to the plate length, where the film top layer does not run to the end of the plate either before it is formed.)

In Fig. 3b you can see the plate cross-section after the formation of the plate edge. The reshaping not only compresses the structure, but also seals the intercapillary space.

The centrally arranged in Fig. 3b nose 4 of the border can also be arranged offset, as shown in Fig. 4a is provided with a rabbet-like nose on the upper plate surface.

Finally, the nose 4 can also be configured as an inner groove, as shown in FIG. 4b.

A rounded outer shape is sketched in Fig. 4c.

The border shapes shown in FIGS . 2 to 4 can be compatible connection options to neighboring constructions. For example, the variant shown in FIG. 4b is to be connected to neighboring plates via "tongue and groove".

In Fig. 5a is a capillary plate is represented as a cross section over the length of plate with a reinforcement rim of a plastic foam. 5 The border, which forms a frame of the same thickness as the capillary plate, is formed on the inside as a counter-shape 6 to the border shape of the capillary plate, on the outside it is shaped to be compatible with a neighboring plate connection with a groove 7 . The for the connection to neighboring plates in the groove 7 a sliding "tongue" (a rectangular profile) is not drawn here (it sits in this case on the neighboring plate or is as a separate profile part in the groove 7 or just if in a groove Neighboring plate inserted).

The advantage of such a construction lies particularly in the form-fitting mounting of the capillary plate in its Reinforcement frame.

This is, for example, mitred from 4 parts, as shown in Fig. 5b as a top view of such a plate construction.

Of course, the frame can also be assembled differently. Its connection at the joints can be adhesive or by plugging together with the appropriate passfor men can be made, which is not shown here.

Fig. 6 finally shows a further possibility to add to the construction of Fig. 5:

A sealing material 8 is introduced between the frame and the capillary plate. This only needs to be pinched, for example. It can also be attached by adding adhesive material.

Fig. 6a shows a cross section through such a plate structure. As a further example of the connection to neighboring structures, the reinforcement edge is provided with a fold 10 here.

Fig. 6b shows the top view of Fig. 6a. Here you can see the shape of the inner groove at the end of the plate, in which the seal is inserted and by the edge "spring" 9 is pressed sealingly.

The joints of the reinforcement frame are shown with dashed lines Lines indicated.

It should also be noted that within the capillary plate catch or also within the reinforcement material additive reinforcing strips, e.g. made of metal or solid art fabric that can be built in, which stiffen the edge have as a consequence. Such deposits can also be made from the umran protrude and e.g. as connecting parts to the neighbor serve constructions. They can also be used as inserts  e.g. with thread (inside or outside) to be Bolting techniques for anchoring such panels to make it usable.

Finally, it is possible that the border reinforcement two or more, spaced one encloses individual panels on their profiled circumferences.

Fig. 7 shows a cross section through such a plate construction. There are two capillary plates (the upper surfaces of which are closed, for example, only on the outside by a cover film) are arranged within a plastic reinforcement frame.

The use of thin translucent capillary plates, the overall arrangement of the same plate thickness the reinforcement border results in cost-saving Advantages.

The thickness of the plate construction does not always need to be the same that of the border reinforcement.

Fig. 8 shows the arrangement of a thin capillary plate within a thicker reinforcement frame.

Such a structure can e.g. advantageous for transportation or storage, because the capillary plate surface is spared.
