Angular pipe guide bend

The present innovation relates to an angular pipe guide bend For the connection of heating pipes laid in the floor area with radiators or a heating circuit distributor, with the pipe guide bend the heating pipe laid in the floor area when it emerges from the screed layer, for connection to a radiator or a heat distributor, is supported in a certain bending radius. This ensures that the heating pipe is guided and deflected accordingly, without the risk of kinking the heating pipe. This bend has two connections, the central axes of which are at right angles to each other stand. One connection takes the pipe laid in the ground, while the other connection, which is perpendicular to it, the heating pipe in the direction of the radiator or heating distributor connection.

The pipes are usually laid on a concrete cast Ceiling with insulation attached. After installation, the pipes are cast in what is known as the screed. It is therefore necessary

so that the pipe guide bends are attached. Ji

Since it often happens that several pipe bends next to each other each arch must be attached, which is particularly difficult because the distance between the arches is small. Through this the time required is also increased.

The present innovation is therefore based on the task of a to design angled pipe guide bend of the type mentioned so that the installation is facilitated with simple means.

To solve the problem, it is provided according to the innovation that on the outer surfaces of the pipe guide bend in the corner area coupling elements for a form-fitting connection with a correspondingly designed one Rohrführungboyen are provided.

It is now possible in a very simple way, several pipe guide bends to be lined up and put together to form a block, since the coupling elements are only engaged by a force application are bring. The block formed in this way can then with relatively few fasteners attached to the ground. To connect the individual arches, the fact that they are made of an elastic material, such as plastic, whereby the resilient properties of the material and the shape of the coupling elements are used can be.

According to a preferred embodiment it is provided that the Coupling elements are arranged on three outer surfaces. This makes it possible for the pipes to be connected to be at an angle to one another can stand.

Further characteristics and features of an advantageous embodiment of the present innovation are the subject of further subclaims and result from the following description of preferred embodiments

leadership example. Show it:

1 two pipe guide bends connected to one another in a perspective view with parallel arrangement of the pipe connections,

2 shows a representation corresponding to FIG. 1, but in which the Pipe connections are at an angle to each other,

3 an elevation of a pipe guide bend in accordance with the innovation,

4 is a top view corresponding to FIG. 3,

5 shows a further embodiment in elevation; and FIG. 6 shows a plan view corresponding to FIG. 5.

In the embodiment shown in FIGS. 1 and 2, there are two angular pipe guide bends 1 connected to one another by coupling elements 2, which will be explained in more detail. Each pipe guide bend 1 is with a horizontal connection 3 for one on the Floor laid heating pipe and a vertically extending connection 4 for receiving the heating pipe in the direction of a not shown radiator or a heating circuit s' ·? distributor provided. In the corner of the pipe guide bend 1 are on three sides the coupling elements 2 provided in the projection seen describing a U-shaped contour. Provided that the pipes connected to the horizontally extending connection 3 are parallel to one another run, the connection of two pipe guide bends takes place as shown in FIG. 1, after which the legs of the U-shaped contour that are parallel to one another are used in each case. Unless the

Pipes are at an angle according to FIG. 2 to each other, is at

a pipe guide bend of the legs that are parallel to one another connecting web of the U-shaped contour connected to a parallel web of the other pipe guide bend. Results from the figures easily that more than two pipe bends together can be set.

3 and 4, a first embodiment of the coupling elements 2 can be seen in more detail, according to which a locking groove 5 and on each side

Viegener - 4 -

a locking cam 6 is provided. The locking groove 5 and the locking cam 6 are, seen in cross section, designed in the manner of a segment of a circle, the central angle being over 180 °. As in particular from the Fig. 4 recognizable, a weiterar pipe guide bend can be connected in alignment with the bend shown there, since the locking groove and the Latching cams on the opposite sides of the pipe guide bend are mutually offset from one another. From Fig. 3 it can be seen that the coupling elements or the locking grooves 5 and the Latching cams 6 extend over part of the height of the pipe guide arch. To fix it on the floor 3 fastening tabs 7 are also provided in the area of the horizontally extending connection.

In the embodiment shown in dew FIGS. 5 and 6, the Locking grooves 5 and the locking cams 6 are trapezoidal. The connection is therefore designed in the manner of a dovetail guide.

Further forms of the coupling elements are within the scope of the present Innovation conceivable. What is essential here is a connection that can be established without tools.
