Description

Technical Field

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

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. During the casting process, steel structures may bend due to process issues, and bent steel structures can be straightened using straightening equipment.

[0003] Chinese patent application publication number CN220461804U discloses a straightening device for steel structures. This invention uses manual traction of a limiting plate to move the slider and upper roller, thereby adjusting the distance between the upper and lower rollers. This allows the straightening equipment to straighten steel of different specifications, increasing its adaptability. The upper and lower rollers perform initial straightening, followed by secondary straightening using an upper and lower pressure plate.

[0004] Although the above-mentioned patented solution can perform secondary correction of steel structures, the correction device in the patent is not convenient for simultaneous correction of all four sides of the steel structure. Currently, most correction devices can only correct the two sides of the steel structure. If it is necessary to correct a circular or narrow steel structure, it is necessary to insert the device into the correction equipment multiple times, which affects the correction efficiency of the steel structure.

[0005] Therefore, a straightening device for steel structures is proposed here. Utility Model Content
