Description

The invention relates to a pipe duct according to the preamble of claim 1 for the production of watertight ceiling, floor and wall openings for the passage of water and sewage pipes.

To achieve a watertight wall penetration, two different techniques are used.

1. Empty pipes are cast into the walls/ceilings when the concrete parts are poured and enable pipes to be subsequently installed in a watertight manner. The tightness is achieved by clamping two flanges against each other and radially compressing a seal arranged between the empty pipe and the pipe feedthrough, which seals the outer empty pipe against the inner pipe feedthrough.

2. Before pouring the ceiling or wall formwork, wooden boxes are installed or the recess is made using recess blocks made of polystyrene, for example. Then after removing the formwork or the recess blocks, the media-carrying pipe is encased in concrete to make it watertight.

Both techniques have the disadvantage that the actual feedthrough pipe must be subsequently installed and sealed, which requires both additional material and time.

Based on the latest state of the art, the invention is based on the task of creating watertight wall openings in concrete walls for the passage of water, waste water, gas, pipes, etc. in one operation and without additional formwork and formwork material and without significant damage to the formwork. The pipe duct, which is attached to the formwork using polystyrene rings before the concrete walls are poured, is also the media-carrying pipe, which can be connected to further pipes using commercially available couplings without additional assembly effort.

For sealing, a metal ring is attached in the middle and covered with bitumen-SBS block polymer rubber sealing tape, thus ensuring double security against water permeability.

Details are described in the drawings using the schematically illustrated embodiments.

Figure 1 shows the pipe duct (1) with the retainers (3) in the installed state. When installing the pipe duct, a cover flange (2) is attached to the formwork wall at the appropriate point using the retaining ring (3). The pipe duct is then inserted into the retaining ring. This is designed in such a way that the pipe duct is fixed in the horizontal direction by the press fit. The second cover flange with the retaining ring is then placed on the pipe duct and the second formwork can be installed. This is shown in Figure 2.

Figure 2 illustrates the pipe duct after removing the formwork and the cover flange with the retaining rings. By removing the retaining rings, the required working space is created, which is needed to connect the further pipes.

Claims (6)

Protection claims 1. Pipe penetration in concrete components characterized in that the duct pipe (1) is used as a formwork body and media carrier. 2. Pipe duct according to claim 1, characterized in that the attached cover flanges (2a, 2b) and retaining rings (3a, 3b) can be used to fasten the pipe duct to the formwork without causing significant damage. 3. Pipe duct according to claim 2, characterized in that the retaining rings (3a, 3b) create the free space (4a, 4b) for the connecting couplings (5a, 5b) of the continuing pipes after removal. 4. Pipe duct according to claim 1, characterized in that lugs (7a, 7b) are attached to the lead-through pipe for fastening to the reinforcement. 5. Pipe duct according to claim 1, characterized in that a metal ring (8) is attached approximately centrally to the entire circumference of the feedthrough tube (1). 6. Pipe feedthrough according to claim 5, characterized in that a sealing strip (9) is attached to the entire circumference of the metal ring (8) and the feedthrough pipe (1).
