Description

Technical Field

[0001] The utility model relates to the technical field of cantilever beams, in particular to a cantilever beam reinforcement structure of a steel structure office building with high assembly efficiency. Background Art

[0002] A cantilever beam refers to a lateral supporting structural element used to support upper beams or floor slabs in a building structure. It is usually composed of steel beams, concrete beams or prestressed concrete beams. It carries the load of the upper structure and transfers it to the lower load-bearing structure.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN220433933U discloses a reinforced beam body connecting steel structure, which belongs to the field of cantilever beams. Its technical key points include connecting steel and a square tube inserted inside the connecting steel, wherein the connecting steel is provided with a first mounting hole, and the square tube is provided with a second mounting hole, wherein the first mounting hole is connected to the second mounting hole, and the connecting steel is provided with a bolt movably inserted through the first mounting hole, and one end of the bolt is provided with a nut through the first mounting hole and the second mounting hole; and a reinforcing structure for reinforcing the bolt is provided inside the connecting steel. By providing the reinforcing structure, the square tube is subjected to excessive force and the middle part is bent downward instantly, and the bolt is subjected to the tensile force of the square tube and has a tendency to deform and break. When the bolt is slightly bent, the force-bearing plate uses the tensile force of the spring to counteract the tensile force of the square tube, which helps to reduce the probability of bolt breakage, thereby achieving the effect of avoiding the square tube from being separated from the steel structure as much as possible.

[0004] At present, most cantilever beam reinforcement structures on the market still have certain deficiencies when used. As shown in the above-mentioned document, the device increases the tensile force of the beam through the load-bearing plate, thereby increasing the strength of the beam. However, the reinforcement structure is more troublesome to install, usually using bolts or welding technology, which makes the operation more troublesome and inconvenient for subsequent maintenance. The bolts are also prone to rust and lock, and there are certain deficiencies when used. Utility Model Content

[0008] The supporting steel and the side of the cross beam are both fixed with fixing blocks, and an extrusion mechanism is arranged inside the fixing block, and the position of the external sleeve block is positioned by the extrusion mechanism.
