Pipe clamp, in particular for heating pipes, water pipes, gas pipes, gutter pipes etc.

The invention relates to a pipe clamp for installation purposes, in particular for heating and plumbing installations, which consists of a clamp ring encompassing the pipe with a clamp upper part and a clamp lower part, which are connected to one another via an articulation point and at their free ends devices for closing of the clamp, wherein an attachment element for attaching the clamp to a wall or the like on Clamp lower part is attached or formed.

In known pipe clamps of this type, the upper part of the clamp and the lower part of the clamp are movable in a hinge-like manner connected with each other. Pipe clamps of this design are particularly suitable for fastening gutter drainpipes known, in which the two clamp ring parts each have a hinge that is connected by a pin. At the two free ends, the clamp ring parts have brackets which are bent at almost right angles and which are connected to a Bore for receiving a screw bolt are provided so that the clamp ring parts engaging around the pipe with one another can be connected. Pipe clamps of this embodiment are due to the design of the hinge, the The associated material and labor costs are relatively expensive.

Finally, pipe clamps made of plastic are known in which the clamp lower part and the clamp upper part are integral are formed, both parts being movably connected to one another by a target bending part. Means This predetermined bending point, the upper part formed on the lower part of the clamp can be moved to a limited extent. The locking both parts are made by a snap-in connection or a snap-lock fastener. It has been found to be disadvantageous in the case of pipe clamps However, this embodiment found that only relatively small pipe diameters - especially in one hanging attachment of the pipelines - from these

Pipe clamps are held because the snap-in connection or the snap-lock fastener absorb only relatively low tensile forces can. Another disadvantage is that the plastic pipe clamp is exposed to the cold becomes brittle and there is a risk that the clamp upper part from the clamp lower part at the predetermined bending point rips off.

The object of the invention is therefore to provide an integrally formed pipe clamp or clamp ring with a clamp upper part and to create clamp base, which is characterized by low manufacturing costs and is able to To accommodate and carry larger diameter pipes.

This is achieved according to the invention in that the Articulation point as merging directly and in one piece in the clamp lower part or clamp upper part on both sides preformed bend or predetermined bending point is formed.

This articulation point in the form of a preformed bend or predetermined bending point can be in a relatively narrowly delimited circumferential area of the clamp ring and arranged essentially opposite to the locking device of the clamp be. However, the invention also offers any other possibility of adaptation to the respective requirements, For example, there is the option of using the clamp lower

part or to extend the upper part of the clamp over a much larger circumferential area of the clamp ring. It is also possible to adjust the joint between the upper part of the clamp and the lower part of the clamp to a relatively wide one To extend circumferential area of the clamp ring.

In the context of the invention, it is also advantageous that the clamp formed from the lower part and the upper part of the clamp The clamp ring and the joint are pressed entirely from sheet metal. The material thickness of the sheet metal strip used can be varied depending on the intended use.

To increase the stability of the clamp lower part and the clamp upper part is preferably up to the Formed joint point extending stiffening beads, but in the supporting clamp lower part Corrugations can be made stronger than in the upper part of the clamp. This allows the suspension in an advantageous manner the upper part of the clamp can be increased or varied.

Due to the one-piece production from only one sheet metal strip, an economical and Achieve efficient production of the pipe clamp according to the invention.

As can be seen from the example in FIG. 1, the pipe clamp according to the invention consists of the half-ring-shaped one Clamp upper part and the semi-ring-shaped clamp lower part 2. Both clamp ring parts 1 and 2 are made in one piece Steel band shaped and formed by a bead 3 forming the bending point, which extends over the entire width extends, and runs parallel to the joint axis 4, connected to each other. The clamp foot 5 is immediately on Clamp lower part 2 molded or arranged. Both clamp ring parts have outwardly projecting beads 6, 7 stiffened, which are parallel to the respective side edges of the clamp lower part and the clamp upper part extend. The beads 6, 7 are designed with a semicircular cross section. It comes instead, however any other conceivable cross-sectional shapes are also possible. At the two free ends of the clamp ring parts 1 and 2, the elements of a locking connection known per se are attached or formed. The locking connection elements 8, 10 are designed so that for locking (see FIGS. 4 and 5) the nose 8 in the im substantial right-angled flap 9 fully occupies the slot 10 so that the Locking connection elements 8, 9 are secured against lateral displacement.

In the pipe clamp shown in Figure 2 is the Connection between the clamp ring parts 1a, 2a given by the predetermined bending point 11, the beads 12 and 13 extend from both sides to the actual intended bending point 11 (see also FIG. 8).

One would first have to assume that the hinge point formed by a preformed bend H or a predetermined bending point 11 does not provide sufficient stability to hold the latching lug 8 securely in the latching slot 10, but surprisingly this design of the hinge point ensures that these latching fastener parts 8 and 8 are held together securely 10 guaranteed when the clamp is closed.

The pipe clamp shown in Fig. 3 has a clamp lower part 15 which is also reinforced by beads 14, however, in this embodiment, the upper part of the clamp 16 is smooth, that is to say without beading. At the predetermined bending point A slot 18 is formed for the purpose of weakening the material. Due to the bead-free training, the Resilience of the upper part 16 increased.

In contrast to the embodiments already described, both free ends of the clamp ring parts 15, 16 is provided with tabs 19, 20 which are also substantially bent at right angles (see FIG. 6). The one when closing

the pipe clamp superimposed tabs 17, 18 are each provided with a bore 21 and are through connected by a screw bolt.

Figures 7 and 8 show different embodiments of a predetermined bending point. For the purpose of material weakening For example, a slot 22 extending parallel to the joint axis can be formed at a predetermined bending point be. However, it is also possible to have a number of bores 23 or the material weakening on a sole bending part through a series of offset holes 24.

In the Sollbiegestsllen shown in Figure 8 the beads 25, 26 are designed such that they come from both sides up to the actual intended bending point are formed.
