Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a convenient assembly and recyclable hydraulic reverse jacking and tightening device. Background Art

[0002] In recent years, with the rapid development of building construction technology, the requirements for the bearing capacity of structures during building construction have become higher and higher. During the construction of many buildings, large equipment or measures are required for the operation on top of the concrete floor slab, which will cause the designed bearing capacity of the concrete floor slab to be unable to meet the on-site construction requirements, and there are certain safety hazards. Therefore, it is necessary to temporarily reinforce the concrete floor slab to meet the construction requirements. For the temporary reinforcement of the concrete floor slab, a more commonly used method is to use round steel pipes to perform reverse jacking at the bottom of the concrete beam. However, if a conventional whole round steel pipe is used for reverse jacking, the phenomenon of inability to tighten will occur, which will cause large deformation of the concrete beam and have an adverse impact on the structure.
