Description

Technical Field

[0001] This utility model relates to the technical field of steel column connection brackets, and specifically to a connection bracket for steel columns. Background Technology

[0002] Steel columns are industrial products, constructed from steel. They are used in large and medium-sized industrial plants, long-span public buildings, and high-rise buildings. Steel columns are commonly used in large and medium-sized industrial plants, long-span public buildings, high-rise buildings, lightweight mobile homes, work platforms, trestle bridges, and scaffolding. Steel columns can be classified by cross-sectional shape into solid-web columns and lattice columns. Solid-web columns have a single, integral cross-section, most commonly an I-shaped section; lattice columns have a cross-section divided into two or more limbs, connected by bracing or plates, which reduces steel consumption when the load is large and the column is wide. Steel columns are also generally classified by stress conditions into axially compressed columns and eccentrically compressed columns. The longitudinal pressure on an axially compressed column coincides with the centroidal axis of the column's cross-section. An eccentrically compressed column bears both axial pressure and bending moment, and is also called a compression-bending member.

[0003] Some existing steel structure components typically use a single bolt and sliding sleeve to reinforce the steel column. Because the bolt has a small point of action on the steel column, its stability is poor, and it is prone to loosening in the later stages of use, which may cause certain safety hazards. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a connecting bracket for steel columns.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connecting bracket for steel columns, comprising a connecting seat, the upper surface of which is slidably connected to the lower surfaces of two connecting frames, and two mounting plates are welded to opposite sides of the inner walls of the two connecting frames, the upper surface of the connecting seat is fitted to the lower surface of the base, and a steel column body is fixedly connected to the upper surface of the base, the front and back sides of the steel column body being fitted to opposite sides of the inner walls of the two connecting frames.

[0006] Preferably, the upper surface of the connector has two slots, the inner wall of the slots is fitted with inserts, and the upper surfaces of the two inserts are fixed to the lower surfaces of the two connectors respectively.

[0007] Preferably, four screw holes a are respectively opened at the four corners of the upper surface of the connecting seat, and the inner wall of the screw hole a is threaded with a stud a.

[0008] Preferably, the two connecting brackets are connected by bolt threads on opposite sides.

[0009] Preferably, the upper surface of the mounting plate is provided with a screw hole b, the inner wall of the screw hole b is threaded with a stud b, the bottom end of the stud b is rotatably connected to the upper surface of the fixing plate, and the front of the fixing plate is slidably connected to the front of the inner wall of the connecting frame.

[0010] Preferably, two sliding rods are fixedly connected to the upper surface of the fixing plate, and sliding holes are slidably connected to the outer surface of the sliding rods. Two sliding holes are opened on the upper surface of the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses two connecting brackets that are close to each other and fixed with bolts. The two connecting brackets clamp the base and the steel column body. Rotating the stud b causes the fixing plate to move downwards. The fixing plate moves downwards and fits against the upper surface of the base, fixing the base and the steel column body within the connecting brackets and connecting seats. This solves the problem that the existing device has poor stability and is prone to loosening in the later stages of use, which may cause certain safety hazards. Attached Figure Description
