A hinged steel structure node

Abstract

The invention belongs to the technical field of steel structures and particularly relates to a hinged type steel structure joint. The hinged type steel structure joint comprises a square steel columnand a steel I-beam; the left side surface and the right side surface of the square steel column are each provided with a pair of installing lugs; an upper connecting plate and a lower connecting plateare installed between each pair of installing lugs, wherein a reinforcing plate is connected to the upper connecting plate and the lower connecting plate; the reinforcing plates on the two sides forma closed loop; flange plate fixing lugs and web fixing lugs are fixedly connected to the surfaces of the reinforcing plates; the flange plate fixing lugs are connected with flange plates of the steelI-beam; and deformation plates are arranged between the web fixing lugs and a web of the steel I-beam. Through the annular structure formed by the reinforcing plates, the square steel column and thesteel I-beam are fixedly connected, the welding surface is small, or the number of holes is small, damage to the structure of an original square steel column and an original steel I-beam is small, andthe structural strength of the connecting point position is relatively high.

Description

Technical field [0001] The invention belongs to the technical field of steel structures, and specifically relates to an articulated steel structure node. Background technique [0002] The steel structure is mainly composed of steel beams, steel columns, steel truss and other load-bearing components made of section steel and steel plates. The components or parts are usually connected by welds, bolts or rivets to form an engineering structure. Because of its high strength and light weight, the steel structure is highly industrialized and easy to construct. The environmental protection is widely used in large-scale factories, stadiums, super high-rises and other fields. [0003] Square steel columns and I-beams are common types of steel structures. For the convenience of transportation, connection nodes are usually not reserved on steel columns. The beams and columns are connected together by welding or bolting at the construction site. Welding or drilling will change the stress stru...

Problems solved by technology

[0004] Welding and bolt connections are rigid connections. When the temperature difference is too large or vibration occurs, the joint position may be damaged under horizontal tension or vibration, which will affect the overall stability and safety of the steel structure.
