A kind of application method of clamping component for prefabrication of reinforcement cage of building foundation

Abstract

The invention discloses an application method of a clamping assembly for prefabricating of a reinforcement cage of a building foundation. The application method comprises the following steps that twooppositely-arranged cylinder bodies are made to act on the two ends of a longitudinal bar correspondingly; one ends of the cylinder bodies penetrate through mounting holes in rotating discs, and nutsare screwed to enable the cylinder bodies to be fastened on the rotating discs; the ends of the longitudinal bar and the axes of the cylinder bodies are aligned till the ends of the longitudinal bar are inserted into the cylinder bodies; pressing rings are rotated and made to move in the direction close to clamping rings along the axes of the cylinder bodies, and contacting blocks arranged obliquely on pressing blocks are made to make contact with the inner side walls of annular bulges; the bulges squeeze the contact blocks to enable the inner side walls of the pressing blocks to get close tothe axes of the cylinder bodies, and thus squeezing between the inner side walls of the pressing blocks and the outer circumferential wall of the longitudinal bar is achieved; in this way, repeated operation is conducted on multiple residual longitudinal bars; and when the two ends of the multiple longitudinal bars are both fixed, transverse bars are wound on the outer wall of a reinforcement skeleton formed by the multiple longitudinal bars according to the spiral track, and the contact points of the transverse bars and the longitudinal bars are welded.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an application method of a clamping component for the prefabrication of a building foundation reinforcement cage. Background technique [0002] During the construction of bridges, culverts or high-rise buildings, the foundation may be piled according to requirements. The method is to use machine punching and water mill drilling, and the hole depth meets the design requirements, and then lower the reinforcement cage to the pile hole, and then insert the conduit for concrete pouring . And when the concrete structure is a columnar or strip-shaped member, the central part does not need to be reinforced, and only the reinforcement is arranged under the surface of the concrete member that contacts the air. If the component is independent, it is necessary to prefabricate the reinforcement around the component during construction, and usually the prefabricated reinforcement structur...

Problems solved by technology

[0003] According to the depth of the pile hole, the axial length of the general steel cage is the same as the depth of the pile hole. However, when pouring a pile hole with a relatively long depth, the construction personnel usually splice multiple steel cages of equal length, and then hoist them to In the pile hole, concrete is poured at the end to shorten the construction time; however, since there are many longitudinal bars on the steel cage and they are distributed in a circle, that is, each longitudinal bar needs to be fixed one by one during production to complete the horizontal alignment. Helical winding and welding of ribs; however, the existing fixing parts tend to move relative to the longitudinal ribs when the horizontal ribs are wound, which leads to uneven distribution of the transverse ribs and unsatisfactory welding effect of the transverse ribs. Moreover, when the steel cage is hoisted , the transverse reinforcement is easy to separate from the longitudinal reinforcement, and eventually the strength of the pile hole after pouring cannot meet the construction requirements
