When the structural strength between the prefabricated floor slabs and the prefabricated walls or the structural strength between the prefabricated floor slabs and the prefabricated beams reaches the design requirements, the installation part 100 is removed to facilitate recycling. It is understandable that before hoisting the prefabricated floor slab, it is necessary to check the drawings and the prefabricated floor slab model to prevent wrong hoisting, and at the same time, check the hoisting equipment, do not hoist overweight, and draw the position of the slab on the prefabricated wall or prefabricated beam before hoisting. After hoisting, use the measuring instrument to check the plane position and elevation of the prefabricated floor, check the plane position and elevation are correct, and then connect the joints.
