Connection structure of concrete steel column and profile steel

Abstract

The invention provides a connection structure of a concrete steel column and a profile steel. The connection structure comprises a steel column, a channel steel, a connecting plate and a plurality ofconnecting units. The channel steel is fixedly connected on the connecting plate, the connecting plate is fixedly connected with the steel column through the connecting units, and the connecting unitsare closely contacted with the connecting plate and the steel column respectively. The connection structure of the concrete steel column and the profile steel is added with the connecting plate structure, the contact area between the channel steel and the steel column is enlarged, and the hazard of stress concentration is reduced. Bolts and nuts are applied as connecting units, the operation is simple, the connection strength is high, and the plastic deformation caused by the welding thermal stress caused by the welding connection at the joint between the steel column and the channel steel isavoided, meanwhile the discontinuity of concrete pouring is avoided.

Description

technical field [0001] The invention creates a connection structure between a concrete steel column and a section steel for connecting a steel column and a channel steel beam in a steel 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. Generally speaking, in high-rise buildings with steel structures, steel columns are used as the building skeleton, and concrete needs to be filled in the steel columns at the construction site. On the outer side of the column,...

Problems solved by technology

[0003] In view of this, the present invention aims to propose a connection structure between concrete steel columns and section steel to solve the problem of directly welding channel steel beams on the outside of steel columns, which requires high welding quality and avoids weld penetration and air holes. At the same time, the thermal stress of welding will cause the plastic deformation of the steel column at the connection with the channel steel beam
