Description

The present invention relates to prefabricated wall elements as described in the preamble of claims 1 and 2.

A course of action has emerged over the past few decades. in the construction of buildings, especially office buildings enforced, which usually results in large floors, whose ceilings are supported by pillars and none Space division by bricked or cast from the outset Own walls. For the greatest possible flexibility in design to maintain the respective floors, partition walls are used a, which is usually back-lined with insulation material Gypsum plasterboard exist. Let her through create any room layouts that go beyond that can also be changed afterwards.

The disadvantage of such constructions is that they are made of Plasterboard and insulation material existing walls in complex Way put together at the point of their installation and must be connected to each other, in particular the laying of cable material behind the plasterboard and the attachment of sockets and the like consuming, time consuming and is destabilizing what the cost of such partitions in the Height drives.

The object of the present invention is to provide a way to form To provide partitions that are easy on the spot of their installation assemble and adapt to the local conditions and the easy laying of cables and the like as well as the installation of Allows sockets and the like.

In this connection, US-A-4 439 966 is a prefabricated wall device Known for installation in unfinished buildings and completed rooms, which come from over a kind of tongue and groove connection of modular prefabricated wall elements that can be connected to one another exists, which are insulated on the inside, in the horizontally and vertically running empty tubes for subsequent retraction of lines are arranged. The side access to the empty pipes can here only done through a hole to be set, so that even at disassembly of the prefabricated wall elements constructed as composite elements exact map of the empty pipes must be available, which z. B. in a possible Renovation will not always be the case and therefore presents difficulties brings. Also, the insertion of the empty pipes in the known Ferigwand elements relatively complex. Furthermore, they are provided with a tongue and groove connection Prefabricated wall elements only in one certain direction to each other. From US-A-439 966 known prefabricated wall device has the features of the preamble of Claims 1 and 2.

The height of the prefabricated wall element according to the invention is the local one Circumstances adapted by cutting, the width of the wall elements is customizable through conventional measures. The connection of the individual Wall elements are made from each other by preferably perforated U-profiles, that formed at the construction site in at least on the side edges of the wall elements Grooves are inserted. These U-profiles are also on site adapted to the room height and with connection angles Ceiling and floor attached. The individual wall elements can in this way be assembled one by one until they are on an opposite wall be connected. The connection can be conventional Way, for example with plasterboard, but also with a specially designed fitting element.

The wall element is provided in different module widths suitable for construction, preferably a width of 62.5 cm at full room height. The Wall element consists of a core element that is either a monolithic Structure in the form of a foamed sheet made of PU or PSD foam, a mineral wool compact or another has a suitable filler, but also can be formed as a composite element, with one Gypsum, insulation and / or cardboard supports e.g. horizontal and vertical mineral wool insulation strips are upset. The wall surface is also made of a corresponding flat element or from a mass formed according to the needs and requirements of the Surface made of different materials and can have different thicknesses.

The core element has a thermal insulation Function. In addition, the core element is at least one horizontal and a number of vertical distribution channels provided, the shape of which depends on the production. The horizontal distribution channels are preferably included provided on one side of the core element, while the vertical distribution channels on the opposite side of the core element are arranged. The core element is as Composite element, so the horizontal and vertical distribution channels can be designed such that the spaced insulation strips glued to the carrier material are. If the core element has a monolithic structure, see the horizontal and vertical distribution channels are direct formed in the material of the core element.

By the construction of the wall elements according to the invention including the horizontal and vertical distribution channels the installation of cables is in the respective core element greatly simplified in an advantageous manner, which in turn translates into significant installation time savings. For the electrical installation is on the one Place where there is a switch, an outlet, or something similar to be installed, a hole with the diameter the device box to be installed in the surface element drilled. Above the device installation box is in height of a horizontal distribution channel also a hole for a cavity junction box drilled, which the respective horizontal and vertical channel separating material of the Core element, be it foam or carrier material Plaster, etc. is pierced, so that a connection between the two channels and the cable to be pulled in without additional effort to any point on the wall element can be pushed.

It is possible to design the wall elements in such a way that the wall surface elements at a Initial installation either completely or with regard to individual Have ducts removed to make it easier to lay cables. It is also possible to use the prefabricated wall element exclusively to be provided with vertical distribution channels, whereby this embodiment is particularly suitable for use with suspended ceilings over which the respective Cables are routed to the vertical duct in the desired wall element become.

Finally, a variant of the wall element is also provided, which are applied as a plaster plate on solid walls leaves. The structure of this wall element for solid walls corresponds essentially that of those described above Wall elements, with a core element in turn a has a heat-insulating function. This is preferred only a horizontal channel provided between the vertical distribution channels of the element at the top of the Plate lies. To facilitate horizontal feeding The horizontal channel of cables is on both sides provided with a thin, easily penetrable bridge. The surface of the wall element facing the respective room for solid walls is according to those described above Wall elements covered with a wall surface element, depending on the needs and requirements of the surface from different Materials and thicknesses can exist.
