Construction method of high-rise steel tube concrete composite column

Abstract

The patent of the present invention relates to building construction, and specifically relates to a construction method for high-rise concrete-filled steel pipe composite columns, including the following steps: establishing a BIM model of steel pipe concrete composite columns; performing BIM construction simulation to construct steel pipe concrete composite columns; Anchor bolts corresponding to concrete-filled steel pipe composite columns built by model; hoisting steel pipes for composite columns; column reinforcement binding, concealment and acceptance; column formwork erection; , the front end and rear end of the anchor bolt are inserted into the positioning plate used to fix the anchor bolt; the BIM model can be used for convenient and quick material management during the installation process, and the front end and rear end of the anchor bolt can be set before pre-embedding Insert the above positioning plate without worrying about greater deviation due to the addition of other components. Combined with fixing the above positioning plate with anchor bolts front and back, it can improve construction efficiency and ensure accurate positioning and installation of construction components to improve safety performance.

Description

technical field [0001] The patent of the present invention relates to building construction, in particular to a construction method for high-rise concrete-filled steel tube composite columns. Background technique [0002] In recent years, with the continuous and rapid development of my country's social economy and construction science and technology, there are more and more high-rise and super high-rise buildings. "Technical Regulations for Concrete Structures of High-Rise Buildings" (JGJ 3-2010) stipulates that residential buildings with 10 or more floors or a height greater than 28m or other high-rise civil buildings with a height greater than 24m are called high-rise building structures. When the building height exceeds 100m, it is called a super high-rise building. In order to meet the rigidity, strength and seismic performance of buildings, more and more concrete-filled steel tube composite columns are used in high-rise buildings, especially super high-rise buildings. ...

AI Technical Summary

Problems solved by technology

However, in the construction of traditional concrete-filled steel pipe composite columns, there are large dimensional deviations in the manufacture of steel pipe components that affect on-site installation, inaccurate opening sizes and positions make it difficult to intersect beams and reinforcements, waste corners formed by processing are a waste of materials, and the installation sequence and direction are difficult. Errors, rework, etc. are insufficient, and in the construction of pre-embedded anchor bolts in concrete composite columns, if the matching size deviation between the anchor bolt and the steel tube concrete composite column is too large, the installation and assembly will be unstable, and multiple debugging is required. In the case of uneven force on the bolts, repeated effect adjustments are required, which also leads to low construction efficiency and even potential safety hazards
