Pipe-suspension bracket

Abstract: A pipe-suspension bracket comprises at least a first bracket part (1) which is provided with an attachment means (4) for suspension of the bracket, the bracket part (1) extending over an angle of more than 180°, preferably between 220° and 230°, in the circumferential direction. The attachment means (4) is attached to a first end section of the first bracket part (1). Consequently, the first bracket part (1) is in the shape of a hook into which a pipe can be placed. A second bracket part (2) may complete the suspension bracket so as to form a bracket which extends over an angle of 360° in the circumferential direction. On the inside, the suspension bracket may be provided with a layer (14) of thermally insulating, vapour-tight material in order to make the suspension bracket suitable for the suspension of pipes for transporting cold media.

Description: The invention relates to a pipe-suspension bracket according to the preamble of claim 1. A bracket of this type is known from CH 278 700 A. In the known pipe-suspension bracket the first bracket part extends over an angle of approximately 180°. A second bracket part is connected to the first bracket part and completes the bracket. The known pipe-suspension bracket has the drawback that, when it is fixed to a ceiling by means of the attachment means, the fitter will have to use both hands to fit a pipe in the bracket, one hand for holding the pipe in the first bracket part and the other hand for fixing the second bracket part. The object of the present invention is to provide a pipe-suspension bracket of the abovementioned type which does not exhibit the abovementioned drawback and which makes it considerably easier to fit a pipe in the bracket. This object is achieved by means of a pipe-suspension bracket according to claim 1. With this pipe-suspension bracket, it is possible, after the first bracket part has been fixed to, for example, the ceiling, a support or the like, to introduce the pipe which is to be placed in the bracket via the bracket opening, after which the fitter can let go of the pipe and carry out other operations which are required. Preferred embodiments of the pipe-suspension bracket according to the invention are defined in the dependent claims. Hereinafter, the invention will be explained with reference to the drawing, in which the single figure is a perspective illustration of a preferred embodiment of the pipe-suspension bracket in a closed state. The substantially annular pipe-suspension bracket which is shown in the drawing comprises a substantially hook-shaped first bracket part 1, which on a first end section is provided with an attachment means 4 for suspending the bracket from a ceiling, a support or the like. From the attachment means 4 the first bracket part 1 extends over an angle of more than 180° and preferably over an angle of between 200° and 250°. In practice, the angle will be between 220° and 230°. The attachment means 4 may, for example, be a welded-on nut into which a threaded rod can be screwed. However, the attachment means 4 may also be of a different form. The first end section of bracket part 1, to which the attachment means 4 is attached, is designed, in the embodiment illustrated, as a protuberance 3 which is directed outwards with respect to the bracket and is substantially U-shaped in cross section, the protuberance 3 comprising two substantially vertical legs 5, 6. In this case, the attachment means 4 is mounted on the connecting part between the legs 5, 6. The pipe-suspension bracket shown in the drawing comprises a second bracket part 2 which by means of one end section is attached to that end section 7 of the first bracket part 1 which is opposite to the first end section, by means of a hinge 8. In the pipe-suspension bracket shown in the drawing, the hinge 8 is composed of a T-shaped end section of the end section 7 of the first bracket part 1, the legs 9 of the T-shaped end section being surrounded by folded-over lips 10 of the corresponding end section of the second bracket part 2. However, the hinge 8 may also be designed in some other way. The second bracket part 2 is designed with a flange 11 which bears against the leg 5 of the U-shaped protuberance 3 of the first bracket part 1 when the bracket is closed. In order to close the pipe-suspension bracket shown in the drawing in a dimensionally stable manner, the bracket part 2 is designed with a drilled hole (not shown), and the leg 5 is designed with a drilled hole (not shown), so that the flange 11 can be fixed to the leg 5 by using a connecting means 13. The connecting means 13 may, for example, be a threaded bolt, in which case the drilled hole in the leg 5 is provided with a screw thread in order to receive the threaded bolt 13. Other components may also be used to form the connecting means 13. The design of the connecting means 13 is not limited to a threaded bolt. On its inside, the substantially annular pipe-suspension bracket shown in the drawing is designed with a layer 14 of thermally insulating, vapour-tight material 14 and is intended to be used for suspending pipes for the transportion of cold media. The size of the layer 14 in the axial direction preferably substantially corresponds to the width of the bracket parts 1 and 2 in the axial direction. The layer 14 preferably consists of a flexible material. Consequently, in the open position of the bracket the layer 14 can simply be bent sideways, so that the pipe which is to be fitted can be placed in the open bracket via a bracket opening 15 which extends between the free end of the leg 5 and the end section 7 of the first bracket part 1, after which the layer 14 can be placed around the pipe, the bracket part 2 can be pivoted upwards and can be securely connected to the bracket part 1 with the aid of the connecting means 13. When the layer 14 is being fitted around the pipe which is to be fitted, a second end section 19 of the layer 14 is joined to a first end section 18 of the layer 14, for example by means of an adhesive. In order to be able to absorb the compressive force imposed by a fitted pipe, the layer 14 is provided with a compression-resistant section 16 which is embedded in a thermally insulating and vapour-tight manner in the layer 14. The section 16 is positioned substantially diametrically opposite the attachment means 3, is substantially rectangular in shape and is matched to the annular shape of the bracket and the pipe which is to be fitted. The layer 14 is preferably glued to the inside of the bracket part 1 at least in the area of the compression-resistant section 16.
