Device for joining several pipes on different levels, comprising of enveloping tensioning belt and adjustment bolt, acting on combination of concave and convex parts

摘要

The pipe (2) is encircled by a belt (5) made of spring steel with a longitudinal slot (6) positioned at each of its ends, which have a short outer segment (7) bent towards each other. A holding element (11) with one concave area (14) attached to the pipe (2) and concave areas (13) at the top and at the bottom can be joined to the pipe (2) by the insertion of a threaded bolt (17) into a central bore, holding a convex shaped elements (21) attached to the top and the bottom. The matching shapes facilitate a precise tensioning. The resulting system can be joined to other pipes (2) with joint elements (28).
