Reinforcing Construction Method for Main Reinforcement of Platform Beam

Abstract

The invention provides a reinforcement construction method for the main reinforcement of a platform beam: 1) Partially remove the formwork at one end of the beam or open a hole in the formwork at the end of the beam; second step: process a corresponding number of reinforcements in advance according to the number of main reinforcements to be reinforced Reinforcement ribs; 2) Penetrate the reinforcement ribs from the end of the beam in turn, use the pair of wire rods set in the beam to reinforce and lock the side formwork as a backing, and the PVC pipe on the wire rod as a sliding roller, and use a hook to move from Probe into the gap between the main ribs of the beam to hook the ends of the reinforcing ribs, lift and pull forward to guide the reinforcing ribs, and push the reinforcing ribs to the corresponding parts in the beam with force at the same time; 3) Put all the reinforcing bars that need to be reinforced Penetrate all the ribs one by one, lift and adjust the reinforcing ribs to the corresponding height position with hooks, and bind and fix them with iron wires; 4) After the reinforcement of the reinforcing ribs is completed, the formwork or holes at the end of the beam are closed, and the next process is carried out after passing the inspection and acceptance , This method is implemented to reduce the labor intensity of workers, and the amount of labor is less.

Description

technical field [0001] The invention belongs to the construction technical scope of platform beams in construction engineering, and in particular relates to a construction method for reinforcing the main reinforcement of platform beams. Background technique [0002] In the field of building construction, whether it is a civil building or an industrial building, reinforced concrete beams, slabs and columns are our most common structural subjects. Especially in the metallurgical industry, such as high wires, bars, heating furnaces, etc., are almost all reinforced concrete frame structures. The platform beams and slabs have large cross-sectional dimensions, dense steel bars, many bolts and embedded parts, and there are many shear grooves and Reserve holes, etc. [0003] During the construction, the work is usually divided into teams according to the process. After the formwork is erected, it is handed over to the steel bar operation team to bind the steel bars, and then the bo...

Problems solved by technology

[0004] The present invention solves the situation that the beam main reinforcement and stirrups are arranged densely and the beam is provided with reserved holes during the construction of the platform girder reinforcement in the prior art, which leads to the need to cut off the original main reinforcement in the beam and adopt reinforcement reinforcement or The technical problem of inconvenient construction when changing and increasing the main reinforcement
