Description

Technical Field

[0001] The utility model relates to the technical field of floor deck hoisting, in particular to an adjustable steel bar truss floor deck hoisting tool. Background Art

[0002] The truss made of steel bars as the upper chord, lower chord and web members connected by resistance spot welding is called a steel truss. The combined load-bearing plate connected to the bottom plate by resistance spot welding is called a steel truss floor deck, which is conducive to uniform spacing of steel bars and uniform thickness of concrete protective layer, and improves the construction quality of the floor. Prefabricated steel truss floor deck can significantly reduce the amount of on-site steel bar binding work, speed up the construction progress, increase construction safety assurance, and achieve civilized construction. Prefabricated formwork and connectors are easy to disassemble and assemble, can be reused many times, save steel, and meet the national energy-saving and environmental protection requirements.

[0003] During the construction process, due to the heavy weight and large volume of the steel truss floor deck, it needs to be lifted with the help of lifting equipment before construction and installation can be carried out.

[0004] The length of the lifting rope at the end of most lifting tools is fixed. When working in a relatively small or height-restricted space, due to the limited lifting height, an overly long lifting rope will cause the machine to be unable to be lifted to a height sufficient for rotation and adjustment, thereby affecting the normal progress of the lifting work.

[0005] Therefore, it is necessary to provide an adjustable steel truss floor deck hoisting tool to solve the above technical problems. Utility Model Content

When working in a highly restricted space, the equipment can operate normally, by mounting the hook 2 located below on the lower part of the floor deck, and then connecting the hook 1 to the upper part of the floor deck. Through such a connection method, when the connecting mechanism of the lifting tool is broken or other faults occur, the upper hook structure can still stably mount the floor deck, effectively avoiding accidents during the lifting process.

[0008] As a further description of the above technical solution:

[0009] A rotation groove is provided inside the connection frame, and four transfer grooves are provided outside the connection frame.
