DE20301075U1 - Utility service pipe aperture lining bush has circular flange flush-fit with cellar wall - Google Patents

Abstract

A house has a cellar with foundation walls with one or more apertures for gas, water or electricity lines. The aperture (1) is lined by an externally- and internally-threaded bush located by end-flanges (2, 4), seals (6) and lock nuts (7). The flanges (2, 4) are esp. positioned to provide an almost flush surface between the flange outer face and the cellar inner wall.

Description

The invention relates to a wall duct for supply lines, in particular water, gas and electricity lines. The wall duct is fixed in the masonry using flanges and cast using a casting compound.

Flange and centering systems for filling a wall duct are known from the state of the art, but an internal, flush installation of the wall duct with the masonry is not possible without problems with the known systems. Flush installation of the wall duct has the advantage that the supply line can be laid directly in a 90° bend without stress.

As a result, the invention is based on the object of realizing a flange filling system which is particularly suitable for assembly work in narrow areas and allows a flush finish between the wall duct and the masonry (on the basement side).

This object is achieved according to the invention in that a flange is screwed into the wall duct on the inside of the cellar, and a further flange with a locking system is mounted from the outside over the wall duct.

If the wall duct is installed correctly, the cables to be passed through must be able to be laid without stress.

Before the wall duct is placed in the core hole, spacers are clipped on to keep the wall duct centered in the core hole later. The threaded flange is screwed into the wall duct.

The unit is inserted into the core hole from the inside of the cellar. A locking flange is placed on the wall duct from the outside. By moving the locking flange towards the masonry, the clamps on the locking flange lock into the grooves of the wall duct and thus fix the wall duct in the masonry.

The filling compound is introduced via a funnel attached from the outside and the air trapped in the annular space can escape on the inside of the cellar through an opening in the threaded flange.

After the filling process and the mortar hardening, the flanges can be dismantled and reused. The supply line can then be inserted and screwed tightly using sealing packages.

An embodiment of the invention is explained in more detail with reference to the following figures 1, 2, 3, 4 and 5, which show:

Figure 1: A side view of a wall duct with flanges.

Figure 2: A perspective view of the wall duct.

Figure 3: A front view of the wall duct with locking flange and

brackets.

Figure 4: Threaded flange in different views.

Figure 5: Locking flange with clamps in different views.

Figure 1 shows a side view of the wall duct 1 for supply lines that must be laid inside the building (I). The wall duct 1 is fixed with flanges, threaded flange 2 on the inside and locking flange 4 on the outside.

As can be seen from Figure 1, the connection on the inside of the waiter is flush mounted and the wall duct is fixed in the masonry (III) using the clamps 9 of the locking flange 4. The annular space 12 can now be filled using the funnel 8 and the trapped air can escape via an opening 11 on the threaded flange 2. The working position of the clamps 9 is better shown in Figure 2. This shows how the clamps 9 engage in the grooves 10 of the wall duct and fix it.
The clamps 9 are released by pressing the clamps outwards.

Claims (6)

1. Wall duct ( 1 ) for supply lines, in particular for water, gas and electricity lines, which consists of a pipe ( 1 ) with internal threads ( 3 ) on both sides, sealing packages ( 6 ), nuts ( 7 ) and flanges ( 2 , 4 ), characterized in that the flanges ( 2 , 4 ) enable the wall duct ( 1 ) to be installed flush on the inside (I) of the waiter. 2. Wall duct according to claim 1, characterized in that the threaded flange ( 2 ) is equipped with a thread ( 3 ) corresponding to the wall duct. 3. Wall duct according to claim 2, characterized in that the fixing of the wall duct ( 1 ) is effected from the outside (II) via the locking flange ( 4 ). 4. Wall duct according to claim 3, characterized in that the locking flange ( 4 ) is locked via clamps ( 9 ) which engage in the grooves ( 10 ) of the wall duct ( 1 ). 5. Wall duct according to claim 1 to 4, characterized in that the centering of the wall duct ( 1 ) is carried out via spacers ( 5 ). 6. Wall duct according to one or more of the preceding claims, characterized in that the supply line is sealed via sealing packages ( 6 ) and nuts ( 7 ).
