An assembly method of a steel pipe column and a steel beam

Abstract

The invention discloses a novel steel pipe column and shaped steel beam assembling method. Top flange U-shaped steel or channel steel provided with multiple bolt holes is vertically welded to the two sides faces of a steel pipe column with the section closed and is symmetrical about the axis, lower flange U-shaped steel or channel steel provided with multiple bolt holes is correspondingly welded to the lower portion of the steel pipe column, and a shear web provided with bolt holes is welded to the gap between the top flange U-shaped steel or channel steel and the lower flange U-shaped steel or channel steel; an open type steel beam has an open section, a beam end plate is welded to the end of one side of the open type steel beam, a beam end lug plate is welded to the middle of the beam end plate, bolt holes in the beam end plate correspond to those in the top flange U-shaped steel or channel steel and the lower flange channel steel, and the beam end lug plate corresponds to the bolt holes in the shear web. The method is suitable for assembly and connection between the steel pipe column with the closed section and the steel beam with the open section, the anti-seismic property and ductility of a joint can be improved, the bearing capacity of the joint can be improved, brittle failure of the steel pipe column under static force or earthquake action is avoided, and then high earthquake-resistant ductility of a steel frame structure is guaranteed.

Description

technical field [0001] The invention relates to a construction engineering technology, in particular to an assembly method of a steel pipe column and a shaped steel beam. Background technique [0002] Steel pipe columns have the advantages of reasonable stress, beautiful appearance, and convenient anti-corrosion and fire-resistant treatment. They are widely used in towers, bridges, public buildings, medium and high-rise buildings and high-rise structures. However, due to the closed section of the steel pipe column, it is difficult to achieve direct assembly connection with the H-shaped steel beam. At present, the commonly used joint connection methods of steel pipe columns and H-shaped steel beams are: diaphragm type, rib plate type, sleeve type, through-bolt type, single-sided bolt type, etc. Among the above methods, the diaphragm type and the rib plate type connection have higher rigidity and bearing capacity, but the construction is more complicated, and there is a cut o...

Problems solved by technology

[0003] In order to solve the problems of complex assembly of steel pipe columns and shaped steel pipes, low load action and relatively high cost in current construction projects; the invention provides a method for assembling steel pipe columns and shaped steel beams

This method is suitable for the assembly connection between steel pipe columns with closed sections and steel beams with open sections. It can solve the problem that closed sections are not easy to assemble, effectively improve the seismic performance and ductility of joints, increase the bearing capacity of joints, and protect steel pipe columns in static conditions. There will be no brittle failure under force or earthquake, thereby ensuring that the steel frame structure has good seismic ductility
