Abstract

An open-ended duct for installation of e.g. electrical cables is closed by an end-plug with an inner sleeve-fit (1) and an end-cover with a conical array of inedible bristles (7). The plug is firmly anchored in the surrounding duct by e.g. adhesive (6). In a further embodiment the end-plug incorporates an air bleed valve.

Description

The The invention relates to a device for the protection of reusable Sealing elements for pressure gas and watertight sealing of gaps and End points of cable channels, pipes, core holes or concrete troughs.

With Cables occupied or unused cable channels and house entries are currently only sporadically at the endpoints of tubes, canals and structures sealed with gas-tight and watertight sealing elements. Not sealed spaces between cables (bundle) and conduit, tubing or trough, however, allow rodents access into the sewer / pipe / trough system or through core drill holes (house entries) into the interior of buildings.

From the DE 103 43 040 A1 is a protective device for cables known which additionally envelops the cables in the axial direction and protects against Verbiss. This Abdichtmöglichkeit can not be found in the prior art in tube / duct and trough cables, since the prior art, for economic reasons, no additional outer cable sheaths are required. One reason for this is that, on the one hand, the cables themselves can be manufactured with rodent protection elements, and the tubes, channels and troughs themselves protect the laid cables from the outside against biting. Another reason is that the main purpose of tubing and trough cables, the arbitrary insertion and removal of the cable, with additional wrapping with the described protective cover is no longer possible.

From the patent application DE 94 13 888 U1 a device is known which prevents bite damage inside and outside the bodywork of vehicles and which consists of an elastically flexible bristles occupied with fastening strip. Possibilities to use the rodent repelling device described here at end points of compressed gas and watertight cable conduits / ducts or structural waterproofing, for example in buildings with flush mounted to the building and / or projecting from the building Kabelkanalzügen, is not possible for safety and technical reasons. The use of Verbissschutzes described in multiple occupied Kabelkanalzügen (KKZ), for example, in buildings to ZTV-TK network 13, consisting of juxtaposed KK-shaped bricks or KK-introduction plates whose Kabelkanal- (KK) distance is about 36 mm and the KK flush attached to the building, an attachment by means of screwing is impossible. When attached to the cable ducts protruding from the structure, the 0.5 bar gas and water tightness of the duct system prevents the injection of cables with overpressure up to about 16 bar and damages the cables drawn or blown in the cable duct system. For the indicated economic reasons, electrical safety cables also have safety reasons; ungrounded metal fastening strips and / or bristles as rodent defense are inadmissible.

One way to effectively seal the spaces between cable (bundle) and cable duct / tube are in the DE 41 05 625 C2 and DE 692 20 786 T2 described. The seal is realized here from a plastic laminate with metal insert, which is filled by air pressure of about 300 KPa and formed into a sealing body and the space between the cable channel space / core hole and cable (bundle) pressure gas and waterproof seals. The disadvantage of this device is that this is a disposable product. Furthermore, the probe filling system of this device is inefficient to use. For cable assignment, cable re-allocation or biting the device up to 60 minutes must be expended for disassembly. When Verbiss the device this is ineffective as a seal of the system.

Despite the above-mentioned sealing options, it is presumably up to now for economic reasons which due to the one-time application of the products and the lengthy dismantling of patent applications DE 41 05 625 C2 or DE 692 20 786 T2 are given, only a small proportion of cable ducts / tubes and core holes (house entries) with sealing gas pressure and waterproof sealed. For concrete troughs along rails so far no closure is known. The majority of the open channels, pipes, and troughs provide rodents with unimpeded access to the sewer, pipe, trough system or through core drill holes (house entries) even into the interior of buildings.

Rodents, those who live in the (cable) channel systems use these Ways to quickly bypass Distances. additionally Rodents in the canal system are damaged by the plastic sheathing Tighten and damage the cable the cables when sharpening the teeth. Obstacles u.a. Also sealing elements, the usual ways obstruct, can also to be gnawed.

To the Protection against rodents becomes cables without additional rodent-resistant reinforcement or sheathing in cable ducts / pipes laid. Unlocked cable ducts / pipes that provide adequate space for ingress and locomotion, nullify this precaution.

Out the reasons mentioned is the entry of rodents into cable ducts, pipes, concrete troughs or core holes and the unimpeded locomotion in the system through appropriate protective measures to prevent.

The The object of the invention is a reusable device at the interstices and end points of cable ducts, pipes, concrete troughs and core holes is used and the reliable against the entry of rodents into the sewer / pipe system or in buildings seals and protects sealing elements against damage by rodents.

Of the Rodent protection must be universal in a wide range of applications be used, without assistance and without much effort quickly, retroactively and reliable can be assembled and disassembled and even after aging still reliable against the ingress of Protect rodents. About that In addition, the rodent protection for several Applications reusable and represent a cost effective solution.

These The object is achieved with the features of claim 1.

Advantageous embodiments and further developments of the invention will become apparent from the dependent claims.

The final, the respective field of application corresponding modifications of the aforementioned Basic components show the following descriptions.

at Use as a device for the protection of cables or unused cable channels, pipes, concrete troughs or core holes against the ingress of rodents, the device contains bristles from rotting plastic filamants beyond that of rats crushed and destroyed can be. These bristles are fixed to a bracket, for the sake of simple assembly preferably designed at least two parts are. The bristles lie after assembly outside the pipe, channel or Kernbohrlochs or are in troughs as an intermediate protection device within of the trough system so diagonally arranged at unused pipes, channels etc. towards the center of the pipe are aligned. Are occupied pipes, channels, troughs or core holes the bristles of the assembled rodent defense device from outside or at channel intervals to achieve a rodent-proof seal to the cable duct tube.

To the rodent tight sealing of any gaps in multiple cables, is in the gusset in addition a sealing star inserted.

The Rodent repellent device according to the invention Can also be used in cable ducts, the means of compressed air again usable sealing elements pressure gas and watertight sealed are. The two-part holder of the rodent defense device is during assembly introduced between the sealing member and the pipe and with filling of the Tightly attached sealing element.

The The invention is based on exemplary embodiments explained in more detail.
