Connection structure of H-shaped steel and concrete rectangular steel column

Abstract

The invention provides a connection structure of H-shaped steel and a concrete rectangular steel column. The connection structure comprises the rectangular steel column, the H-shaped steel and a connection unit; the H-shaped steel is fixedly installed on a side of the rectangular steel column through the connection unit; the connection unit comprises a connection plate and a fixed element, and theconnection plate is respectively in close contact with the H-shaped steel and the rectangular steel column. The connection structure described in the invention adopts a thread-fastened connection mode, the problem that the joint strength of the rectangular steel column and the H-shaped steel is lowered due to the existence of welding thermal stress after welding connection is avoided, the problemthat the whole strength of a concrete structure is reduced as the local deformation of the rectangular steel column caused by welding gives rise to concrete pouring discontinuity is avoided, and theexpenditure of time for carrying out the welding connection at a construction site is simultaneously reduced.

Description

technical field [0001] The invention relates to a connection structure between H-shaped steel and concrete rectangular steel columns in a cylinder structure building. Background technique [0002] Steel structure building is a new type of building system. In recent years, compared with brick-concrete structure, steel structure building has obvious advantages in environmental protection, energy saving, and factory production. It uses steel plate or section steel instead of reinforced concrete. It has high strength and better earthquake resistance. It adopts on-site installation, which speeds up the construction speed, and at the same time greatly reduces construction waste, making it more environmentally friendly. In general, in high-rise buildings with steel structures, rectangular steel columns are used as the building skeleton, and concrete needs to be filled in the rectangular steel columns at the construction site. However, for H-shaped steel beams, due to their small en...

Problems solved by technology

[0003] In view of this, the present invention aims to propose a connection structure between H-shaped steel and concrete rectangular steel columns to solve the problem of directly welding the H-shaped steel beams on the outside of the rectangular steel columns. The welding thermal stress will cause the rectangular steel columns to The plastic deformation of the joints of the steel beams leads to the discontinuity of the concrete during pouring, which reduces the overall strength of the steel columns
