Abstract

For fastening and suspending pipelines (13), pipe clamps (1) are known which have a support anchor (3) and an opposite holding element (5) which are connected to one another by means of tensioning brackets (6). The clamps (6) have a thread (11) at their free ends so that they can be clamped around the pipeline (13) using a screw nut (12). In order to adapt the pipe clamp to different pipe diameters, the support anchor and / or the holding element has holding bores (19) running in the longitudinal direction of the pipe, into which bolts (20) with bores (21) for passage of the ends (10) of the clamping bracket (6) can be inserted. By rotating the bolts (20) in the respective holding bores (19), the tensioning brackets can be aligned without bending in accordance with the pipe diameter.

Description

The invention relates to a pipe clamp for fastening and Pipe suspension with one placed on the pipe bar and one opposite the anchor on the pipe arranged holding element. The support anchor and the Holding element receiving elements on their free ends have a thread on which to clamp or fix the Clamp on the pipe screw nuts are screwed on. The Clamping brackets are in the middle of the tube shape fits and taper tangentially in their end areas. The Bores are in the receiving elements in the direction of the tan potential extending bracket parts formed and the tra ganker and the holding element are mirror-symmetrical forms. With the pipe clamp, the receiving elements are with the Bores arranged laterally to the mirror plane. A pipe clamp of the type mentioned above is for example from DE 25 16 092 A1 known.

Such pipe clamps are used for suspension and fastening of pipelines used, the clamping bracket a radial Pipe expansion, for example at different temperatures doors of the medium conveyed in the respective pipeline, enable. The use of such pipe clamps is also due to the flexible clamping bracket for different pipe dimensions possible.

In the case of the pipe clamp known from the above-mentioned publication  are used to adapt to different pipe diameters knife in the connections between the support anchor or holding device element and clamping bracket spherical washers and conical cups between switched so that a bend-free self-alignment of the Clamping bracket is made possible. This self-alignment is only in a small frame possible because the holes of the clutch piece through which the tensioning brackets are guided, not from can be judged.

Furthermore, the connection is spherical washer and conical socket only suitable small angle differences between the plane in the one side of the conical pan is flat on a receptacle plate, and the level in which the mother is flat on the the side of the spherical disc facing away from the tape same. With larger angular differences it can be too big Pressures between the spherical washer and the conical socket due to the decreasing contact surface of the spherical washer and cone pan come. In addition, there are those presented here Means for bending self-alignment of the clamping bracket many individual parts, resulting in an elaborately constructed pipe clamp leads.

The invention is therefore based on the object of a tube to create a clamp that is simple and one Bend-free self-alignment of the clamps for adjustment different pipe diameters in a wide range possible.

The object is achieved in that the support anchor and / or the holding element laterally to the mirror plane, in the pipe longitudinal direction device running retaining holes in the bolt with Holes for the threaded ends of the clamping bracket are settable.

The bending-free self-alignment of a clamping takes place bracket by rotating the bolt within the bore of the Holding element through which the corresponding thread end of the Clamping bracket passes through. The rotation of the bolt in the hole  the holding element can be in a wide angular range done so that an adjustment of the clamp to difference lightest pipe diameter is possible. The rotating bolts can on the side facing the nuts, with which the pipe clamp on the pipe are fixed, at least be partially flattened. The nuts can go through Insert a corresponding locking washer against one unintentional loosening can be secured.

The invention is described in the drawing, for example, and is explained in detail with reference to FIG. 1. Here, FIG. 1 shows a sectional view and a side view through an off execution of the invention, wherein as the recording elements, a flattened longitudinal side bolts are seen with through-holes before.

The position number 1 in Fig. 1 denotes a pipe clamp, which essentially consist of a support armature 3 , a holding element 5 and four side clamps 6 , through which the support armature 3 and the holding element 5 are connected.

The clamps 6 have at their free ends 10 a thread 11 on which the screw nuts 12 are screwed. By tightening the screw nuts 12 , the pipe clamp 1 is fixed on the pipeline 13 .

The support anchor 3 or the holding element 5 have holding bores 19 which serve to receive a bolt 20 which is flattened on one side. The bolt 20 in turn has bores 21 for the passage of the free ends 10 of the clamping bracket 6 . By tightening the nuts 12 , the pipe clamp 1 is clamped ge or fixed to the pipe 13 . Between the flattened side 22 of the bolts 20 and the screw nuts 12 there is in turn a locking washer 15 which prevents the screw nuts 12 from being unintentionally loosened. The support anchor 3 has a fastening hole 18 for fastening the clamp 1 . It should be mentioned at this point that only two clamps 6 are provided for the pipe clamp.
