Hoisting method of reinforcement cage

Abstract

The invention discloses a hoisting method of a reinforcement cage. The hoisting method of a reinforcement cage comprises the following steps: a, mounting a reinforcement cage; b, mounting positioning devices on the reinforcement cage; c, adjusting positioning blocks on fixing bases in a sliding mode; d, taking out the reinforcement cage; e, mounting separation mechanisms on the reinforcement cage; f, hoisting the reinforcement cage into a pile casing; and and g, recovering the separation mechanisms. The reinforcement cage can be positioned and stability and safety of the reinforcement cage in a hoisting process are improved. Therefore, a single-group separation mechanism can be arranged and the number of the separation mechanisms is reduced. The positioning devices are horizontally fixed to the reinforcement cage through rotary block installation of the positioning devices, a welding operation of the fixing bases and the positioning blocks are carried out on an outer side of the reinforcement cage, a welding operation space is increased, the positioning blocks are subjected to a sliding adjustment on the fixing bases, the positioning blocks extend out of the fixing bases by a designed distance, the positioning blocks always abut against an inner wall of the pile casing, and a positioning effect of the positioning devices on the reinforcement cage is fully achieved.

Description

technical field [0001] The invention belongs to the technical field of steel cage hanging, and in particular relates to a steel cage hanging method. Background technique [0002] The main function of the reinforcement cage is the same as that of the longitudinal reinforcement of the column. It mainly plays the role of tensile resistance. The reinforcement cage plays a role in restraining the concrete of the pile body so that it can bear a certain axial tension. [0003] During the construction of bridges, culverts or high-rise buildings, the foundation may be required to 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 into the casing in the pile hole, and then insert the conduit. Concrete pouring is performed. [0004] The prior art discloses an invention patent titled a steel cage hanging bar detachment device, steel cage and method of ...

Problems solved by technology

[0005] However, in the above-mentioned detachment device, the hanging plate is plugged into the steel plate at the lifting point, and the top of the hanging plate is connected to the hanging bar. The firmness of the connection between the plate and the hanging bars, if there is a disengagement between the hanging plate and the hanging bars in the detachment device, it will lead to poor stability of the entire steel cage, and there are potential safety hazards; and the steel cage is set When the depth of the pile hole is deep, the hanging bar cannot meet the requirements of lowering the reinforcement cage to a deeper position in the pile hole.
