DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a holding device for the anchorage of single- or multilayer webs to a stationary structural member according to the preamble of claim 1. The invention furthermore relates to a process for anchoring such webs, in particular in the form of air-cushions, to structural members.
From DE-OS 21 22 167 a generic holding device is known by means of which a single-layer web provided with a peripheral thickening can be anchored. Said web can also be called a membrane. In this context a membrane is a structural member consisting of flexible and optionally reinforced plastic material that can e.g. be used for forming roof surfaces. The bead-like peripheral thickening of such membranes is called a piping rim. In addition to single-layer webs, it is also possible to form the webs in particular in a two-layer form, whereby the edges are closed in an air-tight manner. Such two-layer webs can be inflated with air, thus forming cushions, which are mainly used as structural parts for roofs and walls. This kind of cushion has the advantage of being of low weight compared to glass, while being just as light-permeable as glass. This kind of air-filled cushion also has the advantage of guaranteeing a good thermal insulation.
Particularly for the anchorage of such cushions there is merely a construction known so far wherein a holding device usually consisting of aluminum is shaped in a manner that it embraces the piping rim, thus positioning the cushion to a primary structure after fixing. However, the main disadvantage of this construction resides in the fact that the holding device cannot be opened and closed as frequently as desired, as the material will break.
It is therefore the problem of the present invention to provide a holding device for the anchorage of single- or in particular multilayer webs to a stationary structural member, allowing a simple assembly and disassembly of the webs at low costs.
This problem is solved by the holding device of the present invention.
SUMMARY OF THE INVENTION
With the holding device according to the invention single-layer webs in the form of membranes provided with a piping rim or also multilayer webs, in particular in the form of the above mentioned air cushions, can be mounted to optional primary structures, like walls, scaffoldings or roof sections, in a most simple and economical manner. It is merely necessary to fix the peripheral thickening or the piping of the web or the cushion in the piping profile and, thereafter, to arrange the piping profile in a receiving space of a girder profile, without requiring a deformation of the profiles or the use of particularly expensive tools.
The holding device according to the invention has the further advantage to consist of individual elements that can be produced easily and economically, that can be exchanged against each other also after the assembly of the holding structure, e.g. when one of the parts is defective.
There also results the advantage of a self-supporting structure which must be supported, on average, only every two meters.
The preferred materials for the holding device are aluminum or glass-fiber reinforced plastic materials (GFK).
It is preferred that the holding device is provided with a top profile which is fixed to the girder profile by means of the web attached to the piping profile, after the piping profile has been inserted. Thus it is possible to additionally secure the piping profile arranged in the receiving space of the girder profile against sliding out, as the receiving space is closed after the top profile has been attached. For fixing the top profile to the girder profile the use of a screwed connection is preferred, which extends through the top profile and engages into a groove at the girder profile. In order to avoid the penetration of dust and water, the screw either is a sealing screw or additional screws are provided in the area of the passage through the top profile.
In order to achieve at least temporary fixing of the piping profile in the receiving
