DE6950007U - LINING PIPE FOR WALL PIPES - Google Patents

Description

Wall penetrations for pipes, cables and earthing devices require a gas- and moisture-proof seal against the surrounding masonry. In the gas and water compartments as well as in the supply of electricity it has become due Naturalized according to existing guidelines and regulations, pipes and cables through walled-in, made of plastic, asbestos-cement or other materials to guide existing protective pipes, so-called casing pipes, and the space between the service pipe (Cable) and casing pipe to be sealed. In most cases this is done by caulking plastic wraps or Strands or elastic rings, preferably made of synthetic rubber, mounted on the ends of the casing pipes, which get to their final place by "rolling up" after they have previously been pulled onto the pipe or cable.

For the much thinner grounding conductors of electrical systems or other facilities to be grounded, there were So far, a suitable wall or wall penetration has not been made, and the earth electrode - in the form of galvanized Round steel or galvanized strip steel - were mortared directly into a wall chisel or wall hole. This type of wall penetration did not provide a reliable seal against gas or gas that could be found in the ground against moisture.

The requirement for a secure seal against the ingress of water or from defective pipelines outside However, gas originating from buildings arises for safety reasons in the wall penetration of earth electrodes to the same extent as with pipes and cables, so that considerations are made, this problem also applies to the To solve the earthing of electrical systems and similar devices.

The content of the present innovation is a moisture and gas-tight wall or wall duct for earth electrodes, which by the nature of their construction from a safe and thereby but very simple construction, high economic efficiency consists.

The wall or wall duct for egg-the (2) electrical systems and similar devices consists, according to the innovation, of a hose or thin-walled plastic tube (6) fitted into a wall bore, preferably with an external Klcberbelag, the ends of which by Guranixstopfcn (31 and ( ¹ I ', through which the earthing element made of galvanized iron or steel band is passed, are tightly closed. The space ζτ, -i.chen is the earthing lciter, the inner wall of the hose (liolires) and the two plugs filled with a plastic sealant used for corrosion protection.

In a modification of the innovation, the space is covered with an elastic, microcellular plastic foam from closed pore structure filled.
