Connection method of high-rise steel structure steel column base and bottom plate reinforcing steel bar

Abstract

The invention relates to a connection method of a high-rise steel structure steel column base and a bottom plate reinforcing steel bar, which comprises the following steps of: welding horizontally arranged reinforcing ring plates on the steel column base, wherein outer edges of the ring plates are rectangular, and a bar penetrating hole is arranged in a plate surface; welding reinforcing steel bar connectors on the end edges at the four sides of the reinforcing ring plates, wherein grooves are arranged on one group of corresponding sides of the four sides of the reinforcing ring plates; welding the reinforcing steel bar connectors through inserting reinforcing steel bars into the grooves; welding the reinforcing steel bar connectors at the other group of corresponding sides through a welding upright plate, wherein the reinforcing steel bar connectors on the two groups of corresponding sides are staggered with each other; transporting steel columns welded with the reinforcing ring plates and the reinforcing steel bar connectors to a construction site; processing external threads on the reinforcing steel bar end heads on the top layer of the bottom plate, and then screwing and connecting the reinforcing steel bar end heads with the reinforcing steel bar connectors to complete the connection of the steel column base and the floor reinforcing steel bar. The invention solves the problem that the site reinforcing steel bars cannot be connected with the steel columns, avoids reserved counterbores without secondary pouring, improves the efficacy and also improves the integral stress performance of the bottom plate and the steel columns.

Description

[0001] Technical field [0002] The invention relates to a construction method of high-rise and super-high-rise steel structure buildings, in particular to a method for connecting the steel column foot of a high-rise steel structure and the steel bar of the bottom plate. Background technique [0003] During the construction of high-rise steel structure buildings, the problem of connection between steel columns and steel bars has become more and more prominent in front of design and construction units. How to effectively and conveniently connect steel components and steel bars is the key point to realize the organic combination of steel structure and steel-concrete structure. At present, in the construction process of inserting the steel column into the bottom plate, the connection between the bottom plate reinforcement and the steel structure generally adopts the conventional bottom plate reserved column pit and welded reinforcement connection plate. The installation accuracy and ...
