Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and more specifically to a maintenance and reinforcement device for an I-beam of a steel structure. Background Art

[0002] Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which have higher strength and better earthquake resistance. In addition, since the components can be manufactured in factories and installed on site, the construction period is greatly reduced.

[0003] I-beams are commonly used in steel structure buildings. They are the main load-bearing beams. During the maintenance and construction of steel structures, workers need to carry out construction work on the surface of the steel structures, so temporary reinforcement devices are needed to reinforce and support the I-beams.

[0004] For example, a steel structure I-beam maintenance and reinforcement device with patent publication number CN216517061U includes an I-beam body, and two abdominal cavities of the I-beam body are both provided with adhesive plates. In the steel structure I-beam maintenance and reinforcement device, when the moving plate moves inward, it presses the two slope blocks to separate and move, so that the two slope blocks are tightly attached to the inner side of the upper and lower wing plates of the I-beam body, thereby enhancing the bearing capacity between the upper and lower wing plates of the two I-beam bodies, and by rotating the rotary plate, the threaded rod presses each pressure plate to fit and press each reinforcement plate, thereby increasing the bending resistance of the upper and lower wing plates, thereby improving the reinforcement effect of the device on the I-beam body.

[0005] When the I-beam maintenance and reinforcement device proposed in the above patent document is actually used, the reinforcement structure needs to be installed between the upper plate and the lower plate of the I-beam, which not only increases the overall weight of the I-beam and increases the burden on the I-beam, but also lacks reinforcement support at the bottom of the I-beam, which easily causes the support strength of the I-beam to be insufficient, affecting the maintenance work of the construction personnel. Therefore, it is necessary to improve the above problems. Utility Model Content
