Pipe fastening.

The innovation relates to a provision for attachment of pipes with axial mobility in pipe clamps, on one half of which a bridge with a sliding foot is attached,

When laying pipelines, the ira use through the medium flowing through them or thermal expansion and thermal expansion that changes due to external atmospheric influences Shrinkage forces are exposed to raüsbon dio fasteners be designed for the pipeline at least in places so that it is under the action of this thermal axial forces on the pipe allow displacement of the same.

Pipelines are usually fixed upright in pipe ducts or pipe bridges and suspended. When hung Pipes, it is possible to compensate for thermal axial forces in a relatively simple manner. The suspension of the

In the device according to the innovation, the web is with its sliding foot in the screwed, welded or otherwise fixedly arranged on the base Sliding shoe guided. Since the friction forces are low due to the slide rails on the slide foot and by using stainless steel for the sliding foot and the sliding shoe, the sliding due to rust formation does not occur can be hindered, is a displaceability when thermal expansion or shrinkage forces occur guaranteed at all times in the longitudinal direction of the pipe.

Fig. 5 is a side view of another embodiment for a pipe fastening device according to FIG

The device for fastening pipes shown in FIGS. 1 to k consists of a web 1 which is connected to a pipe clamp half 3, for example by welding. A sliding foot h , which is guided in a sliding shoe 5, is attached to the bottom of the web 1. The sliding shoe 5 is attached to the base, for example by screwing, welding or the like. In order to reduce the friction between the sliding foot k and the sliding shoe 5, the sliding foot k can have slide rails in the form of studs or webs in the sliding direction or, as in the examples shown in the drawing, knob-shaped or bead-shaped bulges 6 on the sliding surface.

After fastening the sliding shoe 5 on the base and inserting the sliding foot k into the sliding shoe 5, the pipe 8 to be fastened is placed on the pipe clamp half Z> and fixed by placing the other pipe ^{clamp half 3 f} and screwing the pipe clamp together (Fig. And k) .

Basically, it is possible to design the web 1 in the form of a plate and to attach a further plate extending transversely to it as a sliding foot k, e.g. by welding, at its lower end, the web 1, e.g. also by welding, with the pipe clamp half 3 can be connected. On the sliding surface of the sliding foot ^; 4 can then cam- or web-shaped slide rails for

Reduction of friction be molded. In the special embodiment of the innovation-compliant Rohrbef estigun _t '; s device shown in the figures, the web 1 together with its sliding foot k is formed by two sheets la and Ib pressed or folded into the desired shape, which are placed mirror-inverted and connected, for example, by spot welding at 7 could be. Via the ends 2a and 2b of the web parts 1 a and 1 b, which are bent towards opposite sides, the web 1 is connected to the pipe clamp half 3, for example by welding. The sliding foot h is formed by the lower ends of the metal sheets la and Ib, which are also bent horizontally towards opposite sides. In the sliding foot h , knob-like or bead-like bulges 6 are worked into the sliding surface towards the sliding surface, for example pressed in, which extend in the axial direction of the tube 8. In this way, a stable and lightweight design of the fastening device according to the invention for pipes that is advantageous in terms of production technology is created.

5 shows a modification of the device for fastening pipes according to the invention, in which two pipe clamps 3t 3 ¹ arranged at a distance from one another in the longitudinal direction of the pipe to be fastened are connected by a common web 1 which, with its sliding foot, is connected to: Slide shoe 5 is slidably guided in the longitudinal direction of the tube 8 via slide rails 6. With such a fastening device, larger pipes can be fastened in a permanent manner in a longitudinally displaceable manner.

Although the stationary mounting is shown of tubes in the drawing, according to the innovation fastening device can also be used for suspended pipes, with the same design, but rotated about loo ^c and with the nub or bead-shaped bulges 6 in the opposite surface of the Gleitfußes 4, can be chosen.
