[0002] The early sealing of the floor temperature post-casting strip refers to the sealing of the concrete surface within a period of time after the concrete is poured to maintain moisture and temperature, thereby improving the strength and quality of the concrete. The post-casting strip is a concrete strip with a certain width reserved in the beam, slab (including the foundation slab), wall and other structures and poured after a certain period of time to adapt to the influence of factors such as environmental temperature changes, concrete shrinkage, and uneven structural settlement. It can effectively absorb the differential settlement of various parts of large buildings during construction and use, and reduce cracking of beams, slabs, and beams;

[0003] After the current post-cast strip closing plate is installed, a support frame needs to be set at the bottom to support it. However, when the post-cast strip of the floor slab is closed, multiple closing plates need to be installed. Support frames need to be set at the bottom of the closing plates to support the closing plates. Installing the support frames takes a lot of time, which leads to slow installation efficiency of the closing plates. Summary of the invention

At the same time, the extrusion plate 17 pushes the closed bottom plate 2 to move upward through the fixing rod 13, so that the closed top plate 1 and the closed bottom plate 2 can be close to each other to squeeze the floor 3, thereby improving the sealing of the floor 3 after closing. The closed top plate 1 and the closed bottom plate 2 can be fixed by directly twisting the threaded rod 24, thereby improving the convenience of the closed top plate 1 and the closed bottom plate 2 during installation.

When the closed top plate 1 and the closed bottom plate 2 of the present invention approach each other, they push the circular plate 39 to contact, and the circular plate 39 pushes the triangular spring plate 33 to deform through the sliding rod 38. When the center of the triangular spring plate 33 moves, the inclined panel 31 is pushed by the connecting rod 30 to squeeze the sealing block 37. The sealing block 37 is squeezed and moves toward the outer end of the through hole 11 to squeeze the floor 3, thereby further improving the sealing of the floor 3 after closing. The center of the triangular spring plate 33 extends to the inside of the extension groove 32, and the end of the sliding rod 38 away from the triangular spring plate 33 passes through the extension groove 32 and extends to the outer end of the closed top plate 1.

After the contact plate 50 is under pressure, it will contact the end of the floor 3 and squeeze the floor 3. The contact plate 50 positions the closed top plate 1 through the pressure with the floor 3, thereby improving the stability of the closed top plate 1 and the closed bottom plate 2 after installation. The ends of the two center rods 51 that are away from each other are respectively connected with the ends of the closed top plate 1 and the closed bottom plate 2 that are close to each other, and the end of the spring 53 that is away from the positioning plate 55 is fixedly connected to the surface of the contact plate 50, and the end of the contact plate 50 that is away from the telescopic plate 54 is in contact with the end of the floor 3.

After the extrusion plate 17 is limited, the extension of the telescopic rod 16 will push the closed top plate 1 to move downward to squeeze the floor 3. At the same time, the extrusion plate 17 will push the closed bottom plate 2 to move upward through the fixed rod 13, so that the closed top plate 1 and the closed bottom plate 2 can be close to each other. The floor slab 3 is squeezed to improve the sealing performance of the floor slab 3 after being closed. The closed top plate 1 and the closed bottom plate 2 can be fixed by directly twisting the threaded rod 24, which improves the convenience of installing the closed top plate 1 and the closed bottom plate 2. When the closed top plate 1 and the closed bottom plate 2 are close to each other, the circular plate 39 is pushed to contact.
