DE3228055A1 - Cable duct - Google Patents

Abstract

The cable duct proposed by the invention consists of several individual tubes, which are combined into a bundle and drawn into the cable duct. The individual tubes are connected into a tube bundle by means of a profile strip, which extends in the so-called "neutral" fibre in the space between the individual tubes and is pressed in the thermoplastic state against the walls delimiting the intermediate space and welded to this. Here, the individual tubes can consist of smooth as well as corrugated tubes. Advantageously both the tubes and the profile are made of a plastic, preferably thermoplastic.

Description

Cabel Canal

The invention relates to a cable duct with several cable-guiding pipes, preferably corrugated pipes, is occupied, for example from a thermoplastic plastic, whereby the individual tubes of the pipe bundle through a flexible tape are positively connected to each other and the attachment of the The tape on each individual pipe is tangential to the pipe bundle on one side, according to patent application P 3210404.9.

With the invention, an embodiment variant of the main application becomes proposed, which trains this further and can be used for any pipe associations designed.

The invention was based on the object of a cable duct with several own cable ducts in which. the individual pipes of the brought in Pipe association retain their initially predetermined position and with the exception of an improvement the tensile strength of the bandage is reduced by the pulling in of the pipe bandage in the cable duct or when the cable is drawn into the individual pipe reduced and very small bending radii permitted on winding routes with an economical production.

According to the invention this is achieved in that the individual tubes of the pipe bundle at the location of the neutral "fiber in the space between the juxtaposed Pipes are connected to one another by means of a profile running there.

The profile is advantageously that between the individual tubes of the pipe association remaining space adjusted.

The connection of the individual pipes of the pipe association is advantageous made with the profile by placing an extruded plastic profile in the thermoplastic State presses against the surface of the pipes of the pipe association and welded to them.

The advantages of a pipe association produced in this way are especially in it-. that a considerable improvement in the tensile strength of the Association is achieved as well as a significant reduction in the fine pull of the bandage caused by cables as well as the elongation that occurs when the Pipe association itself occurs in the cable duct .. Another.Yorteil is in it to see that thus winding routes even with small bending radii are possible and the use of one or more extrusion profiles at the same time is possible, whereby pipe bundles of different geometries and different Radii of the individual tubes can be produced.

The invention is illustrated below by means of one of the figures Embodiment explained in more detail.

It shows Figure 1 a pipe bundle Figure 2 - another pipe bundle Figure 3 Another pipe bundle and Figure 4 Different profiles.

The pipe association shown in Figure 1 consists of three individual pipes 1, 2 and 3, which are arranged so that the connection of their centers is an isosceles Triangle results. The space that remains between the three tubes 1, 2 and 3 becomes filled with the profile c, the profile at the places def'neutraledt fiber itself is located and connected at its flanks to the surface of the tubes 1, 2 and 3 is, whereby this connection is flawless both with smooth pipes and with corrugated pipes holds because it is made in the thermoplastic state of the profile.

The pipe association shown in Figure 2 consists of four individual pipes 4, 5, 6 and 7, the space between which is filled with profile e.

Figure 3 shows a pipe association with four pipes 8, 5, 10 and 11, whereby tubes of different diameters are interconnected by a profile c between the tubes 8, 9 and 10 and a profile c- between the tubes 8, 10 and 11 connected are, where the profile c- is slightly narrower than the profile c, but the same Has shape.

In this way, larger pipe assemblies with very different Pipe diameters are connected.

Profiles a, b, c, d and e can be full or full Be formed round profiles.

The object of the invention is of course not on the Embodiments shown in the figures and the description are limited. It can also other pipes besides cable duct pipes with each other in this way get connected. Pipes of different materials can also be used. The same goes for the profiles.
