After the positioning block 2 is inserted into the top of the PHC pipe pile, it can restrict the spreader beam 1. When the main beam is suspended on the end of the spreader beam 1, the main beam can be suspended at both ends of the spreader beam 1 at the same time, or the main beam can be suspended on one side of the spreader beam 1.

[0021] The middle part of the upper surface of the spreader beam 1 is fixedly connected to the lifting ring 6 for connecting the lifting device.

[0022] The hook on the lifting lug 3 is used to hang the hand-operated hoist 4.

[0023] The suspension unit is provided in two sets, with adjacent spreader beams 1 fixedly connected by crossbeams 5. Multiple crossbeams 5 are provided and symmetrically arranged at both ends of the spreader beams 1, such as... Figure 1 As shown, the spreader beam 1 and the crossbeam 5 form a rectangular frame structure. Fixing bolts 51 are installed on the crossbeam 5, and through holes matching those on the spreader beam 1 are formed on the crossbeam 5. Multiple through holes for the fixing bolts 51 are formed on the crossbeam 5, allowing workers to adjust the position of the spreader beam 1 on the crossbeam 5 according to the distance between adjacent PHC pipe piles.

[0024] The positioning block comprises a first positioning plate 21 fixedly connected to the beam 1, a second positioning plate 22 slidably connected to the beam 1, and a driving assembly for driving the first positioning plate 21 to slide on the beam 1.

[0025] Working principle: first, the operator rotates the hand wheel to make the first sliding block 203 slide, and the first hinged rod 203 and the second hinged rod 204 contract or expand, so that the distance between the first positioning plate 21 and the second positioning plate 22 matches the inner diameter of the PHC pipe pile. Then, the operator places the temporary suspension device on the top of the PHC pipe pile 7 by using the lifting equipment to hoist the lifting ring 6, and inserts the positioning block 2 into the hole of the PHC pipe pile 7. The temporary suspension device is placed on the top of two PHC pipe piles 7 in the same row to ensure that two or more lifting points are formed on the same side. After the suspension device is placed, the main beam is hoisted below the suspension device by using the lifting equipment, and then the main beam is hoisted by the hoist connected to the hand-operated hoist 4, forming a temporary suspension system. At this time, the lifting equipment for hoisting the main beam can be removed, and the steel is adjusted to the preset position and elevation by the hand-operated hoist 4. After the formwork support system is formed by using the lifting rib and other methods, the hand-operated hoist 4 is loosened, and the temporary suspension device is removed for use in the next working face.
