Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a tool for lifting and placing a reinforcement cage of a supporting pile. Background Art

[0002] Pile foundation is an important part of the structure of building engineering. Pile foundation is in contact with the foundation and is an underground project. When constructing pile foundation, it is necessary to install steel cage and pour concrete. The main role of steel cage is the same as the force of longitudinal steel bars of column. It mainly plays a tensile role. Concrete has high compressive strength but low tensile strength. It restrains the concrete of pile body so that it can withstand a certain axial tension. When constructing bridges, culverts or high-rise buildings, the foundation may be required to be piled according to requirements. The method is to use machine punching and water grinding to drill holes, and the hole depth meets the design requirements. Then lower the steel cage into the pile hole, and then insert the conduit to pour concrete.

[0003] However, when the steel cage is lowered into the pile hole, it usually needs to be lifted and lowered by a crawler crane, and the hook of the crawler crane and the steel cage are connected by only one lifting rod. The lifting rod and the steel cage are welded together. The above method will cause the steel cage to tilt after being lifted, and it is difficult to align the steel cage with the pile hole during the lowering process. Additional personnel are required to assist the steel cage in inserting into the pile hole, which is time-consuming and labor-intensive. It not only does not meet the construction specifications, but also is prone to safety accidents. In addition, the lifting rod is difficult to disassemble, has a poor reuse rate, and is relatively wasteful. In addition, the position of the lifting rod welded on the steel cage is fixed and difficult to adjust. When the position of the lifting rod is not suitable, the lifting rod needs to be welded again at a suitable position, resulting in low lifting efficiency and many defects.
