Description

technical field

[0001] The invention relates to a multi-purpose steering device for external prestressed tendons with variable curvature, which belongs to the field of structural engineering. More specifically, when the present invention uses external prestressed tendons to reinforce existing bridges and buildings, or uses external prestressing technology in new structures, the multi-purpose steering device can well realize various external prestressed tendons. Muscle turning. Background technique

[0002] Prestressed concrete technology is an advanced technology with broad development space in structural engineering. In recent years, my country's prestressed concrete technology has developed rapidly. The design and construction of ordinary prestressed structures have been developed comprehensively, while the research and application of external prestressed structures are relatively few. Compared with ordinary prestressed structures, external prestressed structures have t...
