DE3323187A1 - Device for the noise-damping attachment, especially of pipelines - Google Patents

Abstract

The invention relates to a device for the noise-damping attachment of objects, especially pipelines, to an attachment part which is composed of two attachment angles, which are essentially arranged in mirror-image form with respect to one another, and has two limbs which are parallel to one another as well as two attachment flanges which are in each case bent outwards at right angles and are located in a plane, and having a supporting part which has a contact plate, for the object which is to be attached, as well as two clamping surfaces which run at right angles to the contact plate, and which is clamped in between the limbs of the attachment angles with the interposition of prestressed damper plates consisting of rubber-elastic material, the two attachment angles, the supporting part and the damper plates, which are arranged between the two clamping surfaces of the supporting part and the limbs of the attachment angles, being held together by clamping bolts which pass through at least one of these parts, to form a unit. In order that this device can absorb large forces in the pipe longitudinal direction and transversely thereto, with a simple production capability and easy installation capability, the supporting part (2) is a section of a quadrilateral tube whose one wall forms the contact plate (10), whose walls which are at right angles thereto form the clamping surfaces (11) with their outsides, and whose wall which is opposite the contact plate (10) is clamped in between two damper plates (3), and on at least one ...

Damper plates 3 made of rubber-elastic material. As shown in FIGS. 2, 3 and 4 is to both Side of a pipe clamp 4 such a fastening device arranged.

The fastening part 1 is composed of two essentially mirror images to each other. Mounting bracket 5 and 6, each one leg 7 and one at right angles to it have angled mounting flange 8. The mounting part 1 can. means screws that through screw holes 9 in the mounting flanges 8 on a wall or on a ceiling be screwed on '·· ·

The carrier part 2 has a support plate 10 and two parallel clamping surfaces 11. This support part 2 is formed from a section of a square tube, one wall of which as' Support plate 10 is used, the two walls of which extend at right angles to this support plate 10 their outer sides form the clamping surfaces 11 'and its fourth, running parallel to the platen Wall is supported on at least one support länsch .1 5 of a mounting bracket 5 or 6.

Between the two side walls 11 ' of the support part 2 and the two legs 7 of the fastening part 1 and between the lower, Wall des extending parallel to the support plate 10 Carrier part 2 and the support flange Ί5 of the fastening part 1 are arranged damper plates 3. These Damper plates 3 are so under by means of a clamping bolt and a clamping screw 118 .Tension is set so that the best possible sound insulation is achieved. Here are the clamping bolts 12 and the clamping screw 18 guided through the walls of the support part 2 that a metallic Contact with the walls of the support part 2 is impossible

For this purpose the passages 13 and 14 are provided in the side walls of the support part 2 is considerably larger than the diameter of the clamping bolt 12. Likewise, the passage 17 in the lower wall of the support part ^ 2 is larger than the diameter of the Clamping screw 18. The clamping bolt 12 can, as shown, be a screw bolt, he ■ ■ but can also be a rivet bolt, which extends over annular collars against the clamping surfaces 11 of the Supports mounting bracket 5.6. So that the damper plates 3 their required preload the distance between the coils must be correct to the width of the square tube · as well as be matched to the thickness of the damper plates 3.

To make metallic contact of the

Clamping screw 18 with the lower wall of the support part 2, a damper plate 3 is arranged on both sides of this lower wall of the carrier part 2 and between the inner damper plate 33 and the head of the clamping screw 18 is at least a pressure plate 19 is arranged, which the biasing force Distributed over the surface of the damper plates 3.

The tensioning screw 18 can also be a correctly dimensioned bolt must be replaced. . '

In the illustrated embodiment, 5 and 6 are attached to both mounting brackets one support flange 15 and 16 each arranged, the support plate 16 being arranged so that its' upper side exactly at the level of the underside of the support flange 15 of the other mounting bracket lies. So that the side damper plates 3 can be properly pre-tensioned, the length of the "supporting flanges" is 15 and 16 slightly shorter than the distance between the legs 7 of the two mounting brackets 5 and 6

from each other.

As Figure 3 shows, two

Fastening devices according to the invention serve a fixed bearing a pipeline. large diameter by placing a pipe clamp under the two side flanges 22 4 each has a fastening device arranged. By means of fastening screws these flanges are attached to the support plates of the support parts 2 mounted in a damping manner. The forces acting in the longitudinal direction of the pipe are transmitted by the legs 7 of the mounting brackets 5, 6 recorded. The forces acting transversely to the longitudinal direction of the pipe, in particular the weight the pipeline is taken up by the Tragf lansche.n 15, 16 of the mounting bracket 5.6.
