Prefabricated supporting device for cross-sea bridge pier body reinforcement cage and supervision method thereof

Abstract

The invention relates to a prefabricated supporting device for a cross-sea bridge pier body reinforcement cage, and belongs to the technical field of reinforcement cage machining. The device comprisesa supporting frame, and a supporting assembly is arranged at the top of the supporting frame; the supporting assembly comprises a first wheel disc and amplitude rods; a through hole is formed in themiddle of the first wheel disc; a fixing block is clamped from the circumferential surface of the first wheel disc to the through hole; the fixed block comprises an inner arc part, an outer arc part and a connecting part; the inner arc part is propped against the inner wall of the through hole; the outer arc part is propped against the circumferential surface of the first wheel disc; the connecting part is fixedly connected with the inner arc part and the outer arc part; and the outer arc part is in threaded connection with a fixing screw, the end of the fixing screw abuts against the circumferential face of the first wheel disc, the spoke rods are connected with the fixing block, and the ends, away from the axis of the first wheel disc, of the spoke rods are fixedly connected with fixators used for fixing reinforcing steel bars.

Description

technical field [0001] The invention relates to the technical field of reinforcement cage processing, in particular to a prefabricated support device for a reinforcement cage of a pier body of a cross-sea bridge and a supervision method thereof. Background technique [0002] At present, the reinforcement cage is formed by setting multiple main reinforcements parallel to each other and stirrups welded on the multiple main reinforcements. The circular reinforcement cage needs to fix the main reinforcement first, and then weld the stirrups around the main reinforcement, but the fixing of the main reinforcement requires welding. Temporary steel bar fixing rings not only waste materials but also consume time and energy, which is very uneconomical. [0003] The existing Chinese patent whose notification number can be referred to is CN107119673B discloses a steel cage support device suitable for different pile diameters, which is mainly used for processing steel cages of cast-in-pl...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: there are multiple holes on the outer edge of the wheel, and the lower end of the casing is screwed into the holes. When the number of main ribs is greater than the number of holes, the wheel cannot be used for this type of steel cage. support, and when the number of holes is not an integral multiple of the main ribs, the main ribs cannot be evenly distributed in the circumferential direction of the wheel disc, making the applicability of the support device poor
