A kind of prefabricated support device and supervision method of steel cage for pier body of cross-sea bridge

Abstract

The invention relates to a prefabricated support device for a steel cage of a pier body of a cross-sea bridge, which belongs to the technical field of steel cage processing, and includes a support frame, a support assembly is arranged on the top of the support frame, and the support assembly includes a first wheel disc and a spoke , the middle part of the first wheel disc is provided with a through hole, and the circumferential surface of the first wheel disc is connected to the through hole with a fixed block. The fixed block includes an inner arc, an outer arc and a connecting part. The inner arc and the through hole The inner wall abuts, the outer arc part abuts against the circumferential surface of the first wheel, the connecting part is fixedly connected with the inner arc part and the outer arc part, and the outer arc part is threadedly connected with a fixed screw, and the end of the fixed screw rod is in contact with the first wheel The circumferential surface of the disc is in contact with each other, the spoke rod is connected with the fixed block, and the end of the spoke rod away from the axis of the first wheel disc is fixedly connected with a fixer for fixing steel bars. The present invention has the effect of improving the applicability of the supporting device.

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
