Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a multifunctional all-in-one machine for section steel maintenance and Bailey plate disassembly. Background Art

[0002] Traditional Bailey plate disassembly construction mostly adopts methods such as hammering and burning on the pin shaft. During use, Bailey plates are often easily locked and formed into "multi-pieces" due to uneven force, rust and deformation of Bailey pins. If the "burning + hammering" method is used for disassembly, it will be time-consuming and labor-intensive, with low efficiency and high labor costs.

[0003] Traditional steel straightening construction mostly uses manual straightening methods. During the use of steel, due to collisions, uneven force and other reasons, the upper and lower wing plates are prone to curling and rib bending. In this case, manual steel straightening work has low construction efficiency and high maintenance costs, which is not worth the cost. Therefore, there is an urgent need for a construction method that can be efficient, simple and safe for steel straightening and Bailey plate disassembly. Summary of the Invention
