Problems solved by technology
Beam-column joints are an important part of maintaining the load-bearing performance of steel structures. When the use functions of existing steel structures or the seismic fortification requirements change, it is easy to happen that the bearing capacity of beam-column joints of steel structures cannot meet the new use requirements, or the existing steel structures Due to the design and construction of the structure at that time, the bearing capacity of the beam-column joints was insufficient
How to strengthen the beam-column joints of steel structures whose bearing capacity cannot meet the requirements of use, so as to restore the use function of the structure under the premise of ensuring the safety of the structure, is an urgent problem to be solved in engineering practice

The invention discloses a steel structure beam-column joint haunching reinforcing structure and a manufacturing method thereof. A steel structure beam-column joint is composed of a steel column and a steel beam and is reinforced through a haunch. The haunch is formed by a haunch flange and a haunch web in a welding connection and reinforcing mode. The two ends of the haunch flange are provided with welding grooves, and the haunch web is provided with a first overwelding hole, a second overwelding hole and a clearance hole. The boundary, on the haunch web, of the first overwelding hole is composed of a horizontal line segment, an arc and an oblique line segment. The boundary, on the haunch web, of the second overwelding hole is composed of an arc. The boundary, on the haunch web, of the clearance hole is composed of a horizontal line segment, an arc and an oblique line segment. The haunch flange and a column flange are connected through a first welding line, the haunch flange and a beam flange are connected through a second welding line, the haunch web and the column flange are connected through a third welding line, and the haunch web and a beam web are connected through a fourth welding line.
Description
technical field [0001] The invention relates to the technical field of structural engineering steel structures, in particular to a steel structure beam-column node adding haunch reinforcement structure and a manufacturing method thereof. Background technique [0002] With the development of the economy and society and the increase in the number of existing steel structures, the number of existing steel structures that need to be reinforced and transformed is gradually increasing. Beam-column joints are an important part of maintaining the load-bearing performance of steel structures. When the use functions of existing steel structures or the seismic fortification requirements change, it is easy to happen that the bearing capacity of beam-column joints of steel structures cannot meet the new use requirements, or the existing steel structures Due to the design and construction of the structure at that time, the bearing capacity of the beam-column joints was insufficient.
