Connecting structure of fabricated truss beam and square steel pipe column

Abstract

The invention discloses a connecting structure of a fabricated truss beam and a square steel pipe column. An upper column seat and a lower column seat are correspondingly arranged above and below thesquare steel pipe column, and the truss beam are connected to the two sides of the square steel pipe column; the center of the square steel pipe column is a regular quadrangular prism, a first flangeand a second flange are correspondingly arranged on the regular quadrangular prism in an upper and lower mode, a H-shaped connecting piece is connected to the two sides of the regular quadrangular prism, a connecting plate is arranged outside the H-shaped connecting piece, and bolt holes are uniformly formed in the connecting plate; the truss beam comprises a web member and a channel steel beam, wherein the upper part of the web member is an upper chord member and the lower part is a lower chord member, the upper chord member and the lower chord member are of hollow quadrangular prism structures, and a wing plate is arranged on one surface of the end portion, and the wing plate is connected with the channel steel beam; the upper column seat comprises a square steel pipe upper column and athird flange; the lower column seat comprises a square steel pipe lower column and a fourth flange; and the third flange is connected with the first flange, and the fourth flange is connected with thesecond flange. According to the connecting structure, the bearing capacity of a beam-column joint is improved, the welding process is not performed on site, the construction speed is greatly accelerated, and the construction period is shortened.

Description

technical field [0001] The invention relates to a connection structure between an assembled truss beam and a square steel pipe column, belonging to the field of structural engineering. Background technique [0002] The fabricated steel structure system is a component produced in accordance with specifications and standards. Transport to the construction site, and then quickly assemble and install the produced components. The prefabricated steel structure system has the advantages of light weight, green and environmental protection, so this structure system is widely used. In addition, this structural system has the advantages of fast construction speed and high strength, which meets the needs of my country's construction industrialization. [0003] The fabricated steel structure system requires the structure to have sufficient strength, stiffness and ductility in normal use. Beam-column joints are the key parts of the entire structural system, and the quality of the joint...

Problems solved by technology

[0005] The upper and lower flanges of the middle girder and the web of the traditional all-welded joint are welded together with the square steel pipe column on site. This connection method not only has poor ductility, but also has too many welding parts, resulting in more residual stress. In addition, it also hinders the process of industrialization

As for the full-bolt connection, the traditional connection method is to carry out full-bolt connection between the beam end sealing plate and the column, but this connection method requires workers to put their hands into the square steel pipe column when tightening the bolts, which brings great inconvenience to the construction. At the same time, the bolt holes weaken the column section, which greatly reduces the mechanical performance of the joints
