The embedded frame 2 of the concrete slab 1 is inserted into the outer side of the block 4 of the first precast concrete slab 1. During the splicing process, the top of the ball 9 is squeezed by the inner wall of the embedded frame 2 and is completely retracted to the inner side of the block 4 in cooperation with the spring 6. Then, in the process of pushing the precast concrete slab 1 to splice, the ball 9 rolls on the inner wall of the embedded frame 2 to just below the limiting hole 3. At this time, the top of the ball 9 is not pressed by the inner wall of the embedded frame 2, and the spring 6 can push the ball 9 to move up to the position where the outer wall of the ball 9 bounces into the inner wall of the limiting hole 3.

[0035] The working principle and use process of the utility model are as follows: when in use, after the first precast concrete slab 1 is flattened to a predetermined position, the second precast concrete slab 1 is hoisted and lowered, and the embedded frame 2 of the second precast concrete slab 1 is inserted into the outer side of the block 4 of the first precast concrete slab 1. During the splicing process, the top of the ball 9 is squeezed by the inner wall of the embedded frame 2, and the spring 6 is completely retracted to the inner side of the block 4. Then, in the process of pushing the precast concrete slabs 1 to splice, the ball 9 rolls on the inner wall of the embedded frame 2 to just below the limiting hole 3. At this time, the top of the ball 9 is not pressed by the inner wall of the embedded frame 2, and the spring 6 can push the ball 9 to move up to the position where the outer wall of the ball 9 bounces into the inner wall of the limiting hole 3. At this time, the positioning of the two precast concrete slabs 1 after splicing is completed. At the same time, due to the influence of the ball 9 stuck in the inner wall of the limiting hole 3, the offset amplitude between the two precast concrete slabs 1 will be greatly reduced, which can effectively reduce the offset amplitude of the spliced ​​precast concrete slab 1 caused by the accidental touch of the equipment in the construction environment, and ensure the stability after splicing.
