Problems solved by technology

[0004] However, as an important part of the external prestressed structure, the external prestressed tendon steering device still has some shortcomings: the turning radius of the existing steering device cannot be changed arbitrarily, that is, the turning radius of the external prestressed tendon cannot be flexibly controlled. Steering blocks with a specific turning radius need to be customized, and steering devices with different turning radii cannot be used universally

Abstract

The invention discloses a curvature-variable multipurpose turning device for external prestressed reinforcing steel. The curvature-variable multipurpose turning device comprises a supporting system and a curvature-variable turning system and is characterized in that the supporting system comprises a supporting body and a support plate, and the support plate is fixed to the supporting body; the supporting body is provided with a plurality of displacement adjusting grooves; the curvature-variable turning system comprises a turning component, a first fastening device and a second fastening device, the turning component comprises a plurality of turning units, and the bottom of each turning unit is provided with a groove for placing prestressed reinforcing steel; the first fastening device andthe second fastening device are connected with the turning component, and different turning radiuses can be achieved by adjusting the positions of different turning units on the displacement adjustinggrooves. The curvature-variable multipurpose turning device is safe, reliable, adjustable in turning radius, applicable to the external prestressed reinforcing steel of various diameters, convenientto transport, convenient to mount and the like.

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...
