Steel reinforcement cage overall precast scaffold for wide pier body of cross-sea bridge

Abstract

The invention discloses a steel reinforcement cage overall precast scaffold for a wide pier body of a cross-sea bridge, and belongs to the field of under bridge component construction tools. The steel reinforcement cage overall precast scaffold for the wide pier body of the cross-sea bridge comprises a frame component with all edges detachable, a plurality of grooves are formed in the upper surface of the top edge and the upper surface of the bottom edge of the frame assembly in the length direction, and a plurality of grooves are also formed in the inner surface of the left side edge and the inner surface of the right side edge of the frame assembly in the length direction. The steel reinforcement cage overall precast scaffold for the wide pier body of the cross-sea bridge is high in construction efficiency, high in quality, safe, reliable, and particularly suitable for construction of wide pier body reinforcing bar engineering under severe marine environments.

Description

technical field [0001] The invention belongs to the field of construction devices for bridge substructures, and in particular relates to a construction device suitable for wide pier bodies of cross-sea bridges. Background technique [0002] 1) Construction of traditional pier body reinforcement: [0003] Traditional pier body reinforcement engineering construction: the reinforcement is centrally cut and bent into semi-finished products in the processing plant, and then the semi-finished reinforcement is transported to the construction site for binding. The site reinforcement needs to be assisted by setting up a temporary scaffolding system. Basic construction sequence: Workers bind vertical bars one by one at the site → bind horizontal and horizontal stirrups → install tie bars or supporting steel bars. [0004] 2) Limitations of traditional construction: [0005] In traditional construction, steel bars are centrally unloaded in the processing plant, and steel bars are bou...

[0004] 2) Limitations of traditional construction:

[0005] In traditional construction, steel bars are centrally unloaded in the processing plant, and steel bars are bound on site. It is difficult to accurately control the spacing and protective layer of steel bar binding. In addition, in the marine environment, the working environment of workers is poor, and the steel bars bound on site are vulnerable to typhoons, monsoons, gusts, Influenced by harsh environments such as heavy rain, high temperature, and severe cold, the work efficiency is low, and the working environment is poor, which has a great negative impact on the health and labor enthusiasm of the workers, and is accompanied by a relatively large safety risk. It is difficult to effectively guarantee the construction quality

It can be seen that traditional construction has certain limitations, especially in the construction of wide piers of cross-sea bridges, the limitations are even greater
