H-shaped steel and square pipe assembly type joint and construction method

Abstract

The invention discloses an H-shaped steel and square pipe assembly type joint and a construction method. The H-shaped steel and square pipe assembly type joint comprises a square pipe and H-shaped steel, and further comprises a T-shaped plate, a supporting steel bar, an upper limiting piece and a lower limiting piece; the supporting steel bar is horizontally welded to the side face of the square pipe; an inserting groove corresponding to the supporting steel bar is formed in the side face of a bottom plate of the T-shaped plate; a connecting groove is formed in an end web of the H-shaped steel; a longitudinal plate of the T-shaped plate is in butt joint with the connecting groove and is welded to an upper flange plate and a lower flange plate of the H-shaped steel; high-strength screws are welded to the positions, located above and below the H-shaped steel, of the side face of the square pipe; the upper limiting piece and the lower limiting piece are connected with the high-strength screws in an inserted mode and fixed through high-strength nuts; and the upper limiting piece and the lower limiting piece are connected with the flange plates of the H-shaped steel through high-strength bolts. The H-shaped steel and square pipe assembly type joint is easy to assemble on a construction site, few in assembly procedure, convenient to assemble and disassemble, convenient to use repeatedly, high in construction efficiency, capable of effectively exerting the stress performance of a square pipe column, wide in application range and capable of being widely applied to connection of an H-shaped steel beam and the square pipe.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to an assembled joint of H-shaped steel and square pipes and a construction method. Background technique [0002] The prefabricated steel structure has become a hot spot in the development of the construction industry due to its advantages of light weight, high strength, good seismic performance, fast construction, short cycle, reusable use, and less pollution, especially the modular characteristics, which are more in line with my country's industrialization Development requirements, with good application prospects and market potential. The node is the most critical component of the fabricated steel structure. Its form and performance directly determine the degree of industrialization and structural form of the structure.

Problems solved by technology

The node is the most critical component of the fabricated steel structure. Its form and performance directly determine the degree of industrialization and structural form of the structure. Square steel pipes are the main vertical force members often used in steel structures, and "H" steel is also the most commonly used For laterally stressed members, most of the existing connection methods between H-shaped steel beams and square pipe columns are welded connectors. This method is stable in connection, high in stress strength, and strong in rigidity. The operation is difficult, which affects the construction progress and is not conducive to disassembly. There are also some bolts and connections that adopt the assembled connection method. This method is fast in construction and easy to operate, but it is necessary to open bolt holes on the square pipe in advance. It is easy to cause stress concentration, cause damage to the bolted joints, and make it difficult to use again. Therefore, there is an urgent need for a beam-column assembled joint that is convenient and quick to assemble and disassemble, and has good overall performance.
