Description

Technical Field

[0001] The utility model relates to a multi-functional construction operation platform for precast stairwells, belonging to the technical field of precast stairwell construction. Background Art

[0002] With the continuous development of the construction industry, prefabricated buildings have gradually been recognized by people, and a large number of prefabricated buildings have continuously emerged in urban construction. As an advanced way of stair design and construction, precast reinforced concrete stairs are widely used in prefabricated buildings. However, the precast stairs need to be installed after the main structure construction is completed. Before installation, the temporary up and down channels for construction at the stairwell position mostly use standardized steel stairs. Although going up and down is relatively convenient, it is very inconvenient for workers to carry out construction processes such as the installation, reinforcement, form removal, and concrete pouring of the shear wall aluminum formwork on both sides of the stairwell, and there are certain safety risks. To solve the above problems, there is an urgent need for a device that can improve construction efficiency, safety, and save construction costs. Summary of the Utility Model

The first U-shaped clamp is used for clamping between the vertical steel pipe and the horizontal steel pipe.

[0010] The second clamping member includes a second adjusting rod, a second rotating pipe fitting, a second U-shaped clamp, and a j-shaped clamp. Both ends of the second adjusting rod are threaded posts. The second rotating pipe fitting is threadedly connected to the threaded posts. The second U-shaped clamp and the j-shaped clamp are respectively connected to the two end parts of the second rotating pipe fitting. The second U-shaped clamp is used for clamping on the vertical steel pipe or the horizontal steel pipe. The j-shaped clamp is used for abutting against the side wall of the stairwell ring beam.
