Description

Technical Field

[0001] The utility model relates to the technical field of steel structure reinforcement, in particular to a steel structure reinforcement device. Background Art

[0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. Specifically, steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The purpose of steel structure reinforcement is to improve the bearing capacity, ensure the safety and stability of the structure, extend the service life, and adapt to new uses or environmental changes. Reinforcement is especially needed in environments such as natural disasters, long-term wear and tear, design or construction defects, functional changes or expansions. Currently, it mainly includes welding reinforcement, bolt connection reinforcement, and steel plate bonding reinforcement. In particular, when the bearing capacity of the beam is insufficient, it is necessary to increase the reinforcement amount of the beam, increase its bending bearing capacity of the positive section and the shear bearing capacity of the oblique section, and increase the structural stability of the beam. Conventional bolt connection reinforcement will cause the nuts to rust due to the humid environment, thereby causing the screws to loosen. The conventional diagonal brace reinforcement method has a small force area, resulting in weak stability and insufficient support strength, and all diagonal braces are exposed to the outside, affecting the appearance.

[0003] Therefore, it is necessary to provide a new steel structure reinforcement device to solve the above technical problems. Utility Model Content
