2195GM Insulation and/or light guide element

The invention relates to an insulating and/or light-guiding element for use as an intermediate layer in constructions that serve for sound and/or thermal insulation.

Insulating and/or light-guiding elements or panels with a capillary structure for use in constructions that serve for sound and/or thermal insulation are well known from the state of the art.

DE OS 33 05 885, for example, describes a capillary piece plate for use as an intermediate layer of insulating glass, which consists of capillary pieces made of a thermoplastic that are arranged in a row and are connected to one another by a thermal cut at their end face zones.

DE - GM 91 15 940.7 describes a translucent construction profile for the creation of roof and wall surfaces in conjunction with heat-insulating construction profiles, which consist of a one-piece extruded hollow chamber panel made of a translucent plastic. These hollow chamber panels, which are not comparable to capillary panels in terms of their properties and manufacturing processes due to the dimensions of the chambers, have molded grooves and corresponding sealing folds for connecting individual panels to one another and to connecting profiles of construction profiles.

The object of the invention is to create an insulating and/or light-guiding element for use as an intermediate layer in constructions for sound and/or thermal insulation, which has a capillary structure and can be manufactured in one piece from extruded plastic as the only material component and whose shape enables the elements to be assembled in several levels to form larger blocks to increase stability, for a seamless structure and to minimize waste.

♦♦

According to the invention, the object is achieved by the features of claim 1. Advantageous further developments of the invention are contained in claims 2 to 8.

According to this, the insulation and/or light-guiding element consists of at least one one-piece extruded plastic capillary plate, whereby the opposing front and rear sides as well as side walls of the plates have either at least one groove-shaped depression running over the entire height of the plate or a bead designed as a hollow body for the positive connection of several capillary plates to one another.

The plastic capillary plates consist entirely of a single material component, which enables endless production and whereby these plates can be joined together in a form-fitting manner to form larger and thus more stable blocks by means of the inventive arrangement of the groove-shaped depressions and beads formed as hollow bodies in two levels.

The formation of the beads as hollow bodies results in a lower weight of the panels and a not inconsiderable saving of material.

Furthermore, these beads also serve as spacers in the structures in which these plastic capillary plates are to be used as an element for sound and/or thermal insulation.

Depending on requirements, the capillary plates can consist entirely of a material component made of transparent, crystal-clear, UV-stable plastic or of an opaque plastic material to cover as many areas of application as possible.

Capillary plates made entirely of polymethyl methacrylate (PMMA) or polycarbonate (PC), polyvinyl chloride (PVC), polyether ketone (PEK), polyether ether (PEEK), or polypropylene (PP) have proven to be particularly preferred materials.

According to a further feature of the invention, the individual capillaries (8) have an approximately rectangular, square or triangular cross-section and the side surfaces of the capillaries are approximately 3 -10 mm long. This creates a structure that is responsible for optimal strength and thermal insulation.

According to a further feature of the invention, capillaries are also possible which have an approximately circular to elliptical cross-section with a diameter between 3 and 10 mm.

According to a preferred feature of the invention, the individual plastic capillary plates are approx. 200 mm to 2000 mm wide and approx. 40 mm thick, with the height or length of the plates being adjusted as required. These dimensions of the plates are intended to cover a wide range of applications.

According to a particularly preferred feature of the invention, the wall thickness of the plastic in areas of the plate where forces have to be absorbed is between 200 and 500 μm and in the other areas between 20 and 50 mm. With this special gradation of the wall thickness of the plastic, in addition to optimal material utilization, a high level of stability of the individual plate and of a plate composite is achieved.

The invention will be explained in more detail below using an embodiment.

The elements according to the invention consist of at least one plastic capillary plate (1) extruded in one piece, wherein the respective opposite front and rear sides (2 and 3) and side walls (4 and 5) of the plates have either at least one groove-shaped depression (6) running over the entire height of the plate or a bead (7) designed as a hollow body for the positive connection of several capillary plates to one another.

The elements are used as an intermediate layer in constructions for sound and/or thermal insulation, for example between insulating glass constructions.

The elements are attached within the glass construction, for example, on the outside of the elements in a simple manner using silicone adhesive.

The capillary plates are transparent and are manufactured from a single material component made of crystal-clear, UV-stable plastic in continuous production and cut to the required length using a hot wire.

Preferred plastic materials are polymethyl methacrylate (PMMA), polycarbonate (PC), polyvinyl chloride (PVC), polyether ketone (PEK), polyether ether (PEEK) or polypropylene (PP).

In the present embodiment, the individual capillaries (8) have an approximately square cross-section and the side surfaces of the capillaries are approximately 4 mm long.

The individual plastic capillary plate is approx. 250 mm wide and approx. 40 mm thick, with the height or length of the plates being cut as required.

For example, the wall thickness of the plastic near the areas with the groove-shaped depressions is around 200 mm, since forces have to be absorbed here to connect individual plates. The inner walls of the capillaries in the middle areas of the plate, on the other hand, are only around 30 μm thick and the outer walls in these areas have a wall thickness of around 50 pm.
