DE2615428A1 - Tube joint for masonry or concrete wall - has sockets for seals and plain tube ends for flexible connection - Google Patents

Abstract

The pipe joint is used in masonry and concrete walls. Flexibility of the connection at the penetration is ensured by flexible seals. The joint is formed by a tube element provided with integral sockets (3, 4) on both ends. The plain tube ends (5, 6) are simply pushed into these sockets. Flexible ring seals (7, 8) are placed in the sockets and the tube ends are rolled over them into sockets. The outside face of the penetration tube element can have anchoring features or surface roughness for better embedding into the wall.

Description

Pipe penetration

The invention relates to a pipe penetration for masonry, Concrete walls or the like.

The implementation of pipes through walls prepares for sealing reasons often difficulties and is work and thus according to the previously known solutions expensive.

So-called "pipe-in-pipe constructions" are usually used, the outer pipe being used and walled in when the wall is being built up, and the actual inner tube is now arranged in a sealing manner within the outer tube will.

It can be seen that the cost of materials and the cost of sealing this construction is expensive and it is not even guaranteed that the Inner tube is stored absolutely tight within the outer tube, especially when Earth movements that can affect the inner pipe.

The attachment of sealing flanges is also known.

This construction is also expensive in terms of material and requires expert knowledge Able to achieve the seal in an impeccable manner.

The invention is based on the object of a simply constructed To create pipe penetration. This object on which the invention is based is achieved solved by a push-in end to be connected with sleeves for receiving at both ends provided tubular element.

Through the use of such a double socket pipe is a Bringing up the masonry or the like when pouring the concrete wall. immediately usable Component created, which is preferably in terms of its length of the corresponding Wall thickness corresponds.

After integrating the double socket pipe, it is now possible to in particular using a rolling ring that provides the required flexibility of the connection with simultaneous shear load security, the corresponding to be connected Place pipes with their spigot ends. It is of course possible to use corresponding pipe bends, such pipe bends also already can be provided in the double socket pipe, which then has a length which is of course greater than the respective wall thickness.

The pipe element is preferably made of a wall-friendly material manufactured, for example asbestos cement, so that an intimate connection of the masonry takes place with the double socket pipe, which automatically creates the required seal, for example against groundwater or the like.

is guaranteed.

On the outside of the pipe element, the ability of the pipe element to hold anchoring or roughening that improves the masonry can be provided.

The socket width at both ends of the pipe can be different so that a reduction is achieved automatically, which is often required is. Such special requests are without difficulty in the production of the Pipe element, i.e. the double socket pipe, possible.

An exemplary embodiment of the invention is described below with reference to FIG Drawing explained.

In the drawing, a masonry area is shown very schematically and denoted by 1, which should have a pipe leadthrough. This pipe penetration is created by the double socket pipe 2, the two actual sleeves with 3 and 4 are designated. The pipe can be made of asbestos cement, of course but also from any other known and customary for the production of pipes Be formed material.

Two pipes 5 and 6 connect to the double socket pipe, of which the spigot ends are recognizable. The seal between the inside of the sleeve and the outside of the insertion end 5 or 6 is in each case via a rolling ring 7 or 8, this rolling ring having an essentially round cross-section and with a protruding beyond the ideal cross-sectional circumference of the ring and in The circumferential direction of the ring extending flag is provided, which is opposite her back has a vertically extending stop surface and perpendicular to it an approximately horizontal one running contact surface for the pipe end creates, as well as with an im cross-section of the ring, seen from the back of the flag, less than 1800 away in the circumferential direction of the ring have running groove. This is preferably according to the Teaching of German Patent 2 252 468 proceeded so that the stop surface in is arranged substantially in the region of the central vertical axis of the ring that the flag by a small approach protruding over the circumference of the ring and an incision provided on the side opposite the back of the flag is formed # and that finally the groove in a known manner in the form of a Sector is formed with an apex angle of more than 700.

Through the formation of the rolling ring and the use of such Rollring becomes a flexible, but shear-resistant connection between the spigot ends 5.6 and the sleeves 3.4 reached, so that earth movements of the pipes to be connected without affecting the sealing, which makes the sealing factor the real one Pipe penetration is increased significantly.

It cannot be seen from the drawing, but it is within the scope of the invention that the outside of the pipe is roughened or with anchoring means is equipped, whereby the iiaftbarkeit of the pipe within the wall improves will.

The drawing also does not show the possibility of that the actual double socket pipe 2 is also designed as a reducer, i.e. so that the inner diameter of the sleeves 3 and 4 is different.

Finally, it is possible to use the double socket pipe 2 at the same time to equip one or two elbows so that a corresponding change in the Line routing of the pipes in the area of the pipe penetration can take place.
