DE4231663A1 - Clamp for suspending pipeline - with upper and lower brackets joined by flexible braces around pipe and with angled attachments for tangential clamping to pipe - Google Patents

Abstract

The upper bracket (3) is T-shaped with the ends of the crossbar angled (8, 9) and bored to take the threaded ends of the braces (6). The bottom bracket (4) is flat, with similarly angled ends (14) to take the ends of the braces. The braces are set tangentially to the pipe at the fitting ends. The upper bracket has mounting fittings in the long arm of the T-shape. The ends of the braces are threaded and are secured in the brackets by washers (15) and nuts (11, 12). The washers have tags to prevent rotation. USE/ADVANTAGE - Pipelines for heated fluids. Tangential brace mounting reduces shear strain. Less risk of clamp breakage.

Description

The invention relates to a pipe clamp for fastening and hanging pipes with one on the pipe attachable support anchor and one of the support anchor on the pipe opposite holding element, the support anchor and the holding element receiving elements with holes for Have passage of at least two clamps that have at their free ends a thread on which to Tensioning or fixing the clamp on the tube screw nut tern are screwable and with the clamps in their middle area of the tube shape are adapted and in their End areas end tangent to the pipe.

A generic pipe clamp is, for example, from known from DE 39 15 769.

Such pipe clamps are used for suspension and fastening supply of pipelines used, the clamping bracket a radial pipe expansion, for example under different temperatures of the respective Rohrlei medium promoted. The Ver use of such pipe clamps due to the flexible Clamping bracket possible for different pipe dimensions.  

In the case of the above Publication known pipe clamp are for the passage of the ends of the clamping bracket in one Holding bracket arranged obliquely bores. Two between the retaining tab and the thread on the instep screw nuts screwed on are Di punching sleeves, the end face of which faces the hanging tab Chen beveled so that they are plugged in Fit the condition flat on the hanging tab.

The pipe clamp known from the cited publication is due to the holes to be drilled diagonally and the beveled spacer sleeves to produce relatively complex len and not easy to assemble. There is also especially with vibrating pipes or too tight tensioned ironing the danger that shear forces occur, which can lead to tearing of the clamps.

The invention is therefore based on the object To create pipe clamps that are less expensive to manufacture len and to be assembled and where no shear forces may occur.

This object is achieved in that the support anchor and the holding element are mirror-symmetrical that the receiving elements with the holes to the side of the game are arranged level and that the holes in the Receiving elements in the direction of the tangential Clamping bracket parts are formed.

The pipe clamp according to the invention can essentially consist of there are only three components. The support anchor is in front preferably designed as a rigid T-profile, the Side legs are angled upwards from the tube circumference and its middle leg for attachment or suspension the pipeline. The ones bent upwards  Side legs each have holes for passage the clamping bracket and are preferably arranged so that the top and bottom of the bent parts perpendicular to the tangentially tapering part of the clamping bracket run. Since the support anchor is rigid, in this way the occurrence of shear forces the ends of the clamps avoided.

When designing the support anchors, the on the pipe on the side of the T-profile to be inserted in such a way be bent that the top on part of the Pipe wall fits positively.

In the same way, a U-profile can be used as a holding element bent side legs can be used.

The pipe clamp according to the invention is easy to assemble and can be used for different pipe tolerances will.

To prevent the nuts from coming off which the pipe clamp is fixed to the pipe, for example Loosen vibrating pipes by themselves, can the nuts and legs of the T-Profi les or the U-profile inserted a locking washer be the z. B. with a comprehensive margin over the En the leg rests and is therefore non-rotatable.

In another embodiment of the pipe according to the invention the support anchor can be clamped sideways to the mirror plane have running retaining holes into which bolts are inserted are cash. The bolts can have one or more holes for the passage of the threaded ends of the clamping bracket. Since the bolts can rotate in the holding holes, when tensioning the clamp they lie so that the circumference  area of the hole with the tangentially tapered clamping Align ironing areas. This way, very large ß pipe tolerances are covered, since only under different length clamps must be used.

The rotating bolts can be on the the nuts facing side be at least partially flattened and by inserting an appropriate fuse The screw nuts can prevent an unintentional secured loosening.

The invention is for example be in the drawing is written and is based on the drawings in individual explained. It shows

Fig. 1 shows a section or a side view through a first embodiment with a T-shaped support anchor or a U-shaped holding element and

Fig. 2 is a section or a side view through a second embodiment of the invention, where are provided as receiving elements flattened longitudinal bolts with through holes hen hen.

The position number 1 in Fig. 1 denotes a pipe clamp, which consist essentially of a T-profile 2 as a support armature 3 , a U-profile 4 as a holding element 5 and two side clamps 6 through which the support armature 3 and the holding element 5 are connected are.

The side legs 7 of the T-profile 2 are bent upwards with their outer ends 8 and have bores 9 for the passage of the clamping bracket 6 . The clamps 6 have at their free ends 10 a thread 11 on which the screw nuts 12 are screwed. By pulling on the nuts 12 , the pipe clamp 1 is fixed to the pipe 13 . Between the side legs 7 of the T-profile 2 or between the side legs 14 of the bent U-profile 4 are hedging discs 15 which grip the ends of the respective side legs with a bent edge 16 against rotation.

The surfaces of the T-profile 2 or the U-profile 4 facing the pipe 13 are positively on the circular pipe circumference. The middle leg 17 has a fastening bore 18 for fastening the pipe clamp.

In the embodiment of the pipe clamp 1 shown in FIG. 2, the support anchor 3 or the holding element 5 has holding bores 19 which serve to receive a bolt 20 which is flattened on one side. The bolt 20 in turn has holes 21 for the passage of the free ends 10 of the clamping bracket 6 . By tightening the screw nuts 12 , the pipe clamp 1 is tensioned or fixed to the pipe 13 . Between the flattened side 22 of the bolt 20 and the screw nuts 12 there is in turn a locking washer 15 , which prevents unintentional loosening of the screw nuts 12 .

The support anchor 3 in turn has a fastening hole 18 for fastening the clamp 1 . In contrast to the pipe clamp from FIG. 1, two clamping brackets 6 are provided in the pipe clamp according to FIG. 2.
