Method for controlling deformation during transverse hoisting of reinforcement cage

Abstract

The invention relates to the field of building construction, in particular to a method for controlling deformation during transverse hoisting of a reinforcement cage. The method is characterized by involving steel pipes, two-way hooks, fasteners and a crane, the control method comprises the specific steps that the reinforcement cage is manufactured; the fasteners correspondingly sleeve the two ends of the steel pipes; the steel pipes with the fasteners are correspondingly inserted into the two ends of the reinforcement cage; the two-way hooks are used for correspondingly hooking the fastenersat the two ends of the steel pipes and a main bar of the reinforcement cage, so that the steel pipes are bound on the main bar of the reinforcement cage; and a steel wire rope connected with the cranepenetrates into the steel pipes, the crane is started, and the reinforcement cage is transversely hoisted. When the hoisting method is used, the fasteners can effectively prevent the steel wire ropefrom slipping, the hooks can ensure that the steel pipes can not fall off at will before and after hoisting, so that the deformation of the reinforcement cage in the hoisting process can be effectively reduced through the hoisting method, the whole construction method is simple, convenient, feasible, safe and controllable, and the construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for controlling deformation of a reinforcement cage when it is hoisted horizontally. Background technique [0002] At present, pile foundations in construction are widely used in highways, civil buildings, bridges, etc. Reinforcement cages are an important part of pile foundations, and the quality of reinforcement cages directly affects the quality of pile foundations. In the actual construction process, since there is a certain distance between the steel bar processing site and the pile hole, it needs to be transferred to the hoisting position after the steel bar cage is made. The lifting of steel cages has always been a problem, especially for the lifting of super-long steel cages. During the lifting process, steel cages are prone to deformation and fall, causing casualties and damage to finished products. [0003] After research and investigation, it is found tha...

Problems solved by technology

The lifting of steel cages has always been a problem, especially for the lifting of super-long steel cages. During the lifting process, steel cages are prone to deformation and falling, causing casualties and damage to finished products.

[0003] After research and investigation, it is found that the current common lifting method on the construction site is to use truck cranes or crawler cranes. The lifting point is at the stiffening hoop of the steel cage, or lifting through the lifting lug welded at the position of the stiffening hoop. This lifting method is not safe. , due to reasons such as the welding level of the lifting lugs, the steel cage is prone to fall off during the lifting process, and the steel cage is likely to be deformed during lifting, which affects the quality of the subsequent pile foundation

Or make it in sections, and then weld it at the pile mouth during hoisting. This method is not easy to control the quality of the steel cage, and welding needs to be continued at the pile mouth, which is prone to accidents such as hole collapse
