Problems solved by technology

[0003] At present, there are a large number of welds in the plate-reinforced and flange-enlarged reinforced rigid beam-column joints that are often used in high-rise steel structure industrial and civil buildings. Under the action of earthquakes, stress concentration is prone to occur at the welds, resulting in cracking of the welds. Brittle failure of beam-column joints before the formati

Abstract

The invention discloses an L-shaped special-shaped column and beam fabricated connecting joint, and belongs to the technical field of structural engineering. The L-shaped special-shaped column and beam fabricated connecting joint is composed of a special-shaped column, I-shaped beams, channel steel connecting pieces and high-strength bolt groups. Manufacturing and welding parts of steel componentsare completed in a factory, the welding quality is easy to control, only each prefabricated component needs to be hoisted, and is connected through a high-strength bolt on a construction site, and the construction efficiency is high; and the connecting joint has the advantages of mechanical property and practical property at the same time, and specifically, in the aspect of the mechanical property, the connecting joint makes full use of the bearing capacity and the lateral stiffness of the special-shaped column, and has the good anti-seismic property; and in the aspect of the practical property, the connecting joint emphatically achieves the rapid assembly concept, and solves the "protruding column" problem in a house.

Description

technical field [0001] The patent relates to an L-shaped special-shaped column-beam assembled connection node, which belongs to the technical field of structural engineering. Background technique [0002] The development of steel structure buildings is closely related to the development of steel structure housing industrialization. To realize the industrialization of steel structure housing requires the standardization of parts and components. At present, high-rise buildings are the main direction of my country's construction industry. Therefore, a method suitable for high-rise buildings is proposed. The new high-efficiency assembled standardized steel structure system and the assembled standardized components based on the new steel structure system are the basis for realizing the industrialization of steel structure housing and promoting the development of steel structure buildings. [0003] At present, there are a large number of welds in the plate-reinforced and flange-enl...
