Segmental comparison processing method for reinforcement cage

Abstract

The invention discloses a segmental comparison processing method for a reinforcement cage, and belongs to the field of bridge engineering construction. When a seam welder is adopted to machine the reinforcement cage section by section, a main reinforcement temporary connecting sleeve is arranged at the joint of the reinforcement cage, so that the main reinforcement of the to-be-machined section ofthe reinforcement cage is compared and positioned by taking the main reinforcement of the machined section of the reinforcement cage as a reference; after comparison and positioning are completed, alocking stiffening ring is welded near the joint of the reinforcement cage; after the relative positions of the main reinforcements are locked, subsequent processing is carried out; therefore, it is ensured that all the main reinforcements at the reinforcement cage joint are located in the same axis and abut against each other. The butt joint precision of the main reinforcements of reinforcement cage is improved, the problems that in the prior art, the main reinforcements at reinforcement cage joint are often dislocated, different in length, too large in gap and the like are solved, the structure is simple, operation is easy and convenient, the construction efficiency of reinforcement cage lengthening and lowering is improved, the procedure circulation time is shortened, the risk of pile hole collapse is reduced, and the overall construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of bridge engineering, relates to pile foundation engineering, in particular to a segmented processing technology for realizing high-precision docking of pile foundation reinforcement cages. Background technique [0002] Seam welding machine is the main equipment for pile foundation reinforcement cage processing at present. On the basis of manual assistance, this equipment can organically combine the main reinforcement feeding, stirrup straightening and winding, stirrup and main reinforcement welding and forming processes, so that the reinforcement Cage processing basically achieves standardization, automation, scale and factoryization, improving production efficiency and product quality. In bridge engineering, when the length of the pile foundation is large, the reinforcement cage must be processed in sections, transported to the site and then lowered. When the seam welding machine is used for the segmental processi...

AI Technical Summary

Problems solved by technology

Since there is a gap between the anchoring fixture of the steel bar in the moving plate of the seam welding machine and the main bar of the steel cage, and at the same time, it is affected by the deformation of the main bar itself such as bending and sliding, it is difficult to ensure a one-to-one correspondence between the position and length of the main bar at the joints of the steel cage segments. Problems such as dislocation of the main reinforcement, different lengths, and excessive gaps are prone to occur at the joints of the steel cage segments, which will take a long time to adjust on site, affect the efficiency of pile foundation construction, and increase the risk of pile hole collapse

[0004] Chinese patent CN 205967224 U discloses a device for butt jointing of reinforcement cages, but the device actually only corrects the connection of the formed reinforcement cages, and cannot solve the problem of uneven spacing between the main bars of the reinforcement cage itself, and this application aims to The position of the main reinforcement of the reinforcement cage in the previous section is taken into account during the formation of the reinforcement cage
