Disengaging device of reinforcement cage, reinforcement cage and use method

Abstract

The invention discloses a disengaging device of a reinforcement cage, the reinforcement cage and a use method. The disengaging device comprises a lifting plate, a movable plate and a latch part, wherein the bottom end of the lifting plate is provided with an opening groove for insertion into a steel plate at a lifting point; one end of the movable plate is rotationally connected with the lifting plate and is positioned at one side of the opening groove; the top end of the latch part is rotationally connected with the lifting plate, and is positioned at the other side of the opening groove; thedisengaging device has a hanging state, and when the disengaging device is in the hanging state, the movable plate is rotated, so that the other end and the latch part are positioned at the same sideof the opening groove; an accommodation area is formed between the movable plate and the opening groove, and is used for accommodating the steel plate at the lifting point; the bottom end of the latch part is arranged on the movable plate and the lifting plate in a penetrating way. The disengaging device has the advantages that the movable plate can be closed and opened by the latch part, so as to enable the reinforcement cage to disengage and be repeatedly used; the manufacturing of a lifting bar or an auxiliary cage of the reinforcement cage is reduced, the construction period is shortened,and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of building and bridge engineering pile foundation construction, in particular to a reinforcement cage hanging bar detachment device, a reinforcement cage and a use method. Background technique [0002] In today's building and bridge construction fields, bored piles have become a generally applicable type of pile foundation. With the increasing construction load and later operating load, the requirements for the length of the pile foundation are also getting higher and higher, especially In the field of bridges, 100-meter-long piles have become the norm. As the drilling gets deeper and deeper, the lowering of the reinforcement cages also faces more difficulties. [0003] For bored piles with deep and long holes, the design height of the top of the reinforcement cage is often much lower than the height of the opening, so it is necessary to make reinforcement bars to hang the reinforcement cage at the design height.

Problems solved by technology

[0004] At present, the method of making the auxiliary cage is basically the same as the method of making the steel cage, and the post-hoisting and lowering process is also basically the same, which increases the production time of the steel cage and is very inefficient; and the connection between the auxiliary cage and the steel cage is firm, which is unfavorable. Recycling can only be recycled when the pile head is processed in the later stage, resulting in a great waste of resources and an increase in construction costs
