Construction method of steel box column-concrete beam joint

Abstract

The invention relates to a method for constructing a steel box column-concrete beam joint. The method comprises the following steps of: processing and manufacturing a steel box column, embedding a steel column positioning bolt, hoisting and positioning the steel column, performing concrete pouring and curing in the steel column, performing concrete pouring outside the steel column, installing a frame beam bottom die at the joint, welding frame beam steel bars and the steel box column at the joint, binding and installing the frame beam steel bars, installing a frame beam side die, and performing concrete pouring on a frame beam-column joint. The method is suitable for constructing a concrete frame column-steel box column-concrete frame beam joint in the construction process of a mixed structure, is high in application and popularization value, and has the characteristics that the joint is simply and quickly constructed, the method is easy to master, a transfer joint has high structural integrity, comprehensive construction cost is low, and the like.

Description

technical field [0001] The invention relates to the general building construction technology of E04B in the international patent classification patent classification, especially the steel box column-concrete beam node construction method in which the concrete structure is converted into a steel structure concrete column in the field of special node construction technology of building mixed structure. Background technique [0002] In the known technology, with the wide application of hybrid structures in high-rise buildings and long-span public buildings, more and more hybrid structures are converted from concrete frames to steel structures, and the construction of the conversion nodes is the key to determine the construction quality of the entire structure. [0003] At present, the main traditional methods for converting concrete frames to steel structures are: [0004] 1. Use the pre-embedded high-strength bolts or embedded parts on the top of the concrete column, and reali...

Problems solved by technology

[0004] 1. Use the pre-embedded high-strength bolts or embedded parts on the top of the concrete column, and realize the structural transformation from the column through the bolting of the steel column and the embedded bolts or welding with the embedded parts. This method has high requirements for the embedded high-strength bolts or embedded parts. , the integrity of the transition node is not very good;

[0005] 2. By welding the threaded sleeve on the steel column, the processing thread of the main reinforcement head in the concrete beam and its connection realize the transformation of the steel column-concrete beam transition node. This method has a lot of interference in construction, it is difficult to achieve accurate transition, and the construction quality is difficult to ensure;

[0006] 3. By welding a certain length of strong steel corbel on the steel column and extending into the concrete beam to realize the transformation of the steel column-concrete beam transition node, this method greatly increases the amount of steel used and the project cost is high
