A sway brace fitting clamp is used for lateral bracing of sprinkler or other types of pipe (designated the service pipe) to a structure, to prevent movement of the service pipe perpendicular to the axis of the pipe relative to the structure to which it is attached. The sway brace fitting clamp includes a U-bolt which fits around the service pipe, and a pair of hooks that are coupled to straight ends of the U-bolt, for hooking the sway brace pipe. A pair of nuts engages threaded portions of the U-bolt ends. The nuts may be tightened to pull the sway brace pipe into contact with the service pipe, firmly clamping the sway brace pipe and the service pipe together.

The invention relates to an ascending pipe (10; 110) for guiding thick substances, in particular liquid cement, in order to construct a building. Said ascending pipe comprises a plurality of tubes (14) which are arranged one behind the other in the longitudinal direction of the pipe and are detachably connected to coupling points. According to the invention, at least one of the tubes (14) is supported in a fixed position (40; 140), and at least one other tube (14) is guided in an axially displaceable manner in a guiding element (26) which is mounted in a fixed manner to the construction.
摘要:
Gegenstand der vorliegenden Erfindung ist eine Kupplung, insbesondere eine Rohrkupplung für Hochdruckrohre (1) oder Hochdruckschläuche. Die Kupplung ist mit jeweils an zu verbindenden Enden (3) vorgesehenen Kupplungsstücken (2), und mit einer die Kupplungsstücke (2) mit Hilfe von wenigstens zwei Scherelementen (6) koppelnde Muffe (5) ausgerüstet. Erfindungsgemäß übergreifen die Kupplungsstücke (2) in nahezu durchmessergleicher Verlängerung der Enden (3) die innen liegende Muffe (5).

Die Rohrschelle (1) für die Halterung von Bauteilen, insbesondere in Form eines Rohres besitzt eine im wesentlichen U-förmig ausgebildete Einlage (2), wobei die dem Bauteil zugewandte Seite der Einlage (2) wenigstens teilweise mit einer reibungsmindernden Beschichtung (7) in Form einer Beflockung versehen ist.
摘要:
An electric pipe snubber having an annular housing (15), fixed to a supporting structure (17), surrounding a pipe (3) and a plurality of brake means (23) fixed to the housing (15) and radially disposed about the pipe (31), which are biased into engagement with a serrated section on the pipe (3), and a means for electromagnetically releasing the brake means (23) to permit axial displacement of the pipe (3) relative to the annular housing (15). The brake means (23) have teeth (51) which mesh with the serrations (7) on the pipe. A series of the electric pipe snubbers are provided along a length of pipe (3) together with a control means adapted to release the brake means (23) of one of the series of the snubbers while the remainder of the series remain engaged with the pipe (3).
