Steel frame reinforced column and reinforcing method thereof

Abstract

The invention relates to a steel frame reinforced column and a reinforcing method thereof. The steel frame reinforced column is characterized in that sealing reinforcing steel plates are welded between two flanges at two sides of an H-shaped steel frame column along the overall length of the column, are arranged in pair at two side openings of the H-shaped steel frame column and are welded with two flanges at the opening of the H-shaped steel frame column, and two sealing reinforcing steel plates adjacent up and down are mutually welded. In the invention, the reinforcing steel plates are prefabricated into parts in advance, are directly hoisted to the position during construction, pass through the steel column in over length along the direction of a weak shaft of the H-shaped steel frame column and are welded in pair, thereby enabling the structure stress of the steel reinforced column to be more reasonable and the structural bearing of an original building to be enlarged and satisfying the structural bearing stress requirement. By adopting the construction method of the invention, the original structure can be used for reinforcing the frame steel column of the original steel structure without being disassembled, thereby not influencing the normal work in the original building. All the reinforcing steel plates can be precast in factories, thereby not only shortening the time limit for a project and reducing the construction cost but also ensuring project quality and satisfying the requirement of building extension.

Description

technical field [0001] The invention relates to a reinforcement structure of a building steel frame column and a reinforcement construction method. Background technique [0002] With the rapid development of large-span spatial structure buildings, the structural spans designed by architects are also increasing, the shapes are becoming more and more novel and unique, and the structural connections are becoming more and more complex. Due to historical reasons and the passage of time, the original steel structural components are prone to local damage and corrosion, or due to the small cross-section and low bearing capacity of the components, they cannot meet the requirements of project quality. The existing reinforcement methods cannot transform and reinforce the original structural steel frame columns without unloading the original building. The existing structural reinforcement methods have complex procedures, large investment in turnover materials, and long construction per...
