Reinforcement cage main reinforcement connector connection structure and integral hoisting construction method

Abstract

The invention provides a reinforcement cage main reinforcement connector connection structure and an integral hoisting construction method. The structure comprises a sleeve, a lock net and two main reinforcement connectors which are butted, wherein the wire winding length of one of the main reinforcement connectors equals to the sum of the length of the sleeve, the wire winding length of the lock net and the deviation allowed by the specification, and the length of the other main reinforcement connector equals to the sum of half of the length of the sleeve and the deviation allowed by the specification; internal threads in the same direction are arranged on the inner wall of the sleeve, the end parts of the two main reinforcement connectors are positioned in the sleeve, and half of the long wire connector and half of the short wire connector are positioned in the sleeve. The construction method comprises the following steps: processing a reinforcement cage; numbering each pair of main reinforcement connectors of the reinforcement cage; sequentially hoisting the upper reinforcement cage and the lower reinforcement cage, and connecting pairs of main reinforcement connectors according to the numbers so as to complete the integral hoisting of the reinforcement cage. The construction structure and the construction method are simple, the construction cost is low, the operation is realized easily, and the quality is ensured easily.

Description

technical field [0001] The invention relates to a joint connection structure of main reinforcement cages and an integral hoisting construction method. Background technique [0002] At present, the existing multi-section cylindrical pier reinforcement cage mechanical connection construction method is to build scaffolding around the cylindrical pier, and then lift a single steel bar for butt joint; It takes a lot of time and severely restricts the construction period. During the construction process, the efficiency of single hoisting construction is extremely low; if the steel bars are hoisted manually, the safety factor is low, and if the hoisting is performed by a crane, the machine idle rate is too high; there is currently another The construction method of the overall hoisting of the multi-section cylindrical pier reinforcement cage adopts positive and negative wire sleeves for the joints.

[0002] At present, the existing multi-section cylindrical pier reinforcement cage mechanical connection construction method is to build scaffolding around the cylindrical pier, and then lift a single steel bar for butt joint; It takes a lot of time and severely restricts the construction period. During the construction process, the efficiency of single hoisting construction is extremely low; if the steel bars are hoisted manually, the safety factor is low, and if the hoisting is performed by a crane, the machine idle rate is too high; there is currently another The construction method of the overall hoisting of the multi-section cylindrical pier reinforcement cage, the joint adopts the positive and negative wire sleeves, and the positive and negative wire sleeves are the same as the conventional sleeves when making the overall reinforcement cage

However, the dismantling and hoisting construction before the reinforcement cage is hoisted is extremely difficult. When dismantling, it is necessary to move the two sections of the reinforcement cage to both ends in different directions at the same time to remove the sleeve. The removal requires a lot of manpower, and it is easy to operate carelessly. Distort the cage

When hoisting, because it is a positive and negative thread, it is very difficult to align all the threads and screw in one or two threads and then tighten them at the same time.
