Hoisting device for prefabricated reinforcement cage

Abstract

The invention discloses a hoisting device for a prefabricated reinforcement cage. A plurality of bearing plates are arranged on the outer circumferential wall of a sleeve I in the circumferential direction of the sleeve I, a plurality of vertical plates are arranged on the inner wall of the sleeve I in the circumferential direction of the sleeve I, and a rectangular groove I is formed in the sidewall, deviating from the sleeve I, of each vertical plate; two baffles are arranged at the groove bottom of each rectangular groove I in the axial direction of the sleeve I, the two ends of each baffle are subjected to arc treatment, arc grooves I are formed in the end faces of the two ends of each baffle, and rectangular grooves II are formed in the two side walls of each baffle in the vertical direction; the two rectangular grooves II and the two arc-shaped grooves I communicates end to end to form an annular channel, cavities I are formed in the two ends of each baffle, a chain meshing witha corresponding gear I is movably arranged in each annular channel, the chains are connected end to end, and a sliding block is arranged on the outer circumferential wall of each chain; and a clamping assembly used for clamping a main reinforcement of the reinforcement cage is arranged on the end face, deviating from the groove bottom of the rectangular groove I, of each sliding block.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a hoisting device for a prefabricated steel cage. Background technique [0002] Due to the complexity of the foundation in modern building construction, it is necessary to use concrete piles as foundation support. In the existing concrete column construction technology, the concrete pile and the prefabricated steel cage are constructed separately in the punching hole. The steps are to first level and harden the construction ground, and then position the pile position on the construction ground to build Pile hole, use the crane to put the steel cage into the pile hole; insert the pipe into the pile hole to pour the concrete pile, so that the concrete fills the pile hole section with the steel cage and forms a concrete pile; the concrete pile is removed after hardening The upper layer is inferior; use a crane to lift the steel pipe vertically and put it into the pile hole, and...

AI Technical Summary

Problems solved by technology

[0003] In the current construction method of concrete piles and steel pipe columns, in the construction process, it is necessary to wait for the concrete pile to harden and go deep into the pile hole to remove the inferior layer on the upper layer of the concrete pile, and then carry out the construction of the steel pipe column, which has a long construction period and high cost; The connection strength between concrete piles and steel pipe columns is not ideal. Large-scale pier column reinforcement cages require high dimensional accuracy. Existing hoisting tools are mostly hoisted in sections, and holes have been formed because the reinforcement cages have not been placed for a long time and it is easy to pour concrete. Cause hole collapse or contact between the reinforcement cage and the inner wall of the pile hole when the reinforcement cage is lowered, causing the collapse of the pile hole, easily causing the size deformation of the reinforcement cage, and also causing the contact between the reinforcement cage and the inner wall of the pile hole, resulting in the collapse of the pile hole, affecting the later stage The molding process and the quality of the piers
