Coaxial screw connector for scaffolding framework assemblies - has tubular struts with conical inserts for tensile and thrust forces and threaded spacer

摘要

the coupling end of the tubular frame (2) has a conical tension support (8) screwed into the profile and an outer conical thrust support (5). The inner cone faces inwards and has a threaded centre for the inner end of the connector shaft (10). The outer end of the connector shaft is threaded into joint (1), and the thrust is taken up by the the thrust cone via an outer threaded sleeve (16), inside whose smooth bore the connector slides. The joint is made via the coupling shaft, and the outer threaded sleeve is adjusted to press against the joint to take the thrust forces. The coupling shaft has a collar (13) to limit the adjustment into the tension support and an alignment collar (14) to slide inside the thrust sleeve. ADVANTAGE - Simple adjustment for tolerances, robust frame connections.
