Description

Technical Field

[0001] This utility model belongs to the field of building steel structure technology, and specifically relates to a seismic reinforcement device for building steel structure nodes. Background Technology

[0002] Steel structures are structures primarily made of steel and are an important structural form in modern construction engineering. They consist mainly of steel beams, columns, and trusses made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets, resulting in numerous connection nodes. The connection methods between these nodes are designed according to the specific building requirements. Steel column structures are a common building form, and in actual construction, the steel column nodes are often fully welded. These welds are too close together, even intersecting, creating a large heat-affected zone within a small area of ​​the column node. This affects the load-bearing capacity of the node and weakens its seismic resistance. While this may initially ensure the building's safe use, it cannot guarantee safe use over a long period, thus posing potential safety hazards after prolonged use.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0006] In a preferred embodiment, the building steel structure consists of three sets of steel columns arranged vertically in pairs. The upper left steel column is in contact with the upper support plate, and the two sides of the lower steel column are respectively in contact with the two sets of side support plates.

[0007] In a preferred embodiment, a set of fitting grooves for positioning and fixing the ring hoop are provided on the lower surface of the upper support plate and the rear side of the side support plate.

The two sets of reinforcement seats are respectively placed below the two sets of steel columns set above for auxiliary support and reinforcement. The three sets of fixing rings are respectively fitted onto different positions on the outside of the steel column and the reinforcement seat, thus completing the seismic reinforcement support for the steel structure node of the building.

A set of mounting threaded holes is provided on the rear side of the reinforcing mounting grooves. Two sets of reinforcing mounting blocks are provided in the staggered support member.

[0012] In a preferred embodiment, each of the reinforcing mounting block 1 and the reinforcing mounting block 2 is fixedly connected to a set of connecting rods on the side near the middle support rod 1 and the middle support rod 2, respectively.

[0013] The other end of the connecting rod and both ends of the intermediate support rod one and intermediate support rod two are fixedly connected to a set of mating plates.
