[0002] The composite floor is an assembled integral floor made of prefabricated panels and cast-in-place reinforced concrete layers. Post-cast strips are set at the joints of the composite floors for the later stable connection of two adjacent composite floor slabs. Special filling material slurry is poured on the post-cast strips. In order to prevent excessive leakage of the filling material slurry, it is often necessary to set a corresponding anti-leakage slurry structure at the post-cast strips.

[0003] The existing patent number is CN202222719189.2, which discloses a leakage-proof structure for the post-cast strip of a prefabricated composite floor slab. It discloses that a fastening component is passed through the steel bars and the support plate from top to bottom in sequence and then fastened and connected, so that the support plate and the prefabricated cast-in-place slab are firmly and stably fixed together. However, the connection modules and other structures in the technical solution need to remain in the filling material after pouring, and the connection modules lack stable support for the supporting mold during the connection process, which makes the supporting mold easy to fall during the support installation process and cause danger, and the construction is difficult. Therefore, a leakage-proof structure for the post-cast strip of a prefabricated composite floor slab is needed to improve the stability of the device during use. Utility Model Content

[0039] In actual use, by setting a supporting mechanism, it is convenient to make the aluminum alloy plate 3 abut against the lower surface of the prefabricated floor 2, by setting a mounting hole 10 on the mounting plate 9 and a mounting block 8 on the aluminum alloy plate 3, the mounting block 8 is convenient to be stably clamped in the mounting hole 10, so as to realize the connection between the mounting plate 9 and the aluminum alloy plate 3, and by setting the outer sleeve 12 and the inner sleeve 13 to be mutually socketed, it is convenient to change the height of the outer sleeve 12 and the inner sleeve 13 after the combination, that is, by extending the inner sleeve 13 out of the outer sleeve 12 until the aluminum alloy plate 3 abuts against the lower part of the prefabricated floor 2, and then inserting the limiting bolt 15 on the outer sleeve 12 into the limiting hole 14 on the inner sleeve 13, so as to realize the connection between the outer sleeve 12 and the inner sleeve 13, and at the same time cooperating with the adjusting mechanism, it is convenient to raise the aluminum alloy plate 3 to different heights, so as to adapt to floors of different heights, and the flexibility is strong.

[0040] It should be noted that by setting a limiting mechanism, it is convenient to hang the limiting steel bar 6 on the prefabricated floor 2, so that the aluminum alloy plate 3 is tightly attached to the lower part of the prefabricated floor 2. By setting the screw rod 5 and the nut 7, when the screw rod 5 is rotated, the length of the screw rod 5 extending out of the nut 7 can be changed, thereby changing the height of the limiting steel bar 6 at the end of the screw rod 5, that is, changing the distance between the limiting steel bar 6 and the aluminum alloy plate 3, which is convenient for clamping prefabricated floor slabs 2 of different thicknesses, and has strong flexibility.

[0041] In this embodiment, a sponge rubber strip 4 for abutting against the prefabricated floor slab 2 is provided at the edge of the upper surface of the aluminum alloy plate 3 .

[0042] In actual use, the sponge rubber strip 4 is enclosed at the edge of the upper surface of the aluminum alloy plate 3 to form a rectangle, which is convenient for blocking the gap between the aluminum alloy plate 3 and the prefabricated floor 2 to prevent the concrete poured later from flowing out. In this embodiment, the number of the mounting blocks 8 and the mounting holes 10 are both multiple and correspond to each other one by one.

[0043] In actual use, multiple mounting blocks 8 and multiple mounting holes 10 are arranged in an array, and the mounting blocks 8 are inserted into the mounting holes 10 to achieve assembly of the aluminum alloy plate 3 and the mounting plate 9. Moreover, through the cooperation between the multiple mounting blocks 8 and the multiple mounting holes 10, the aluminum alloy plate 3 is not easy to move on the mounting plate 9, and the connection stability is high.

[0044] In this embodiment, the adjustment mechanism includes a mounting seat 18, a rotating block 21, a threaded rod 22 arranged on the rotating block 21, and a connecting tube 24 threadedly sleeved on the threaded rod 22, the connecting tube 24 is fixedly connected to the lower part of the inner sleeve 13, a bearing 19 is arranged in the mounting seat 18, a rotating rod 20 is arranged in the bearing 19, and the upper end of the rotating rod 20 extends out of the bearing 19 and is connected to the rotating block 21.

By rotating the rotating block 21, the rotating rod 20 and the threaded rod 22 will be driven to rotate at the same time. When the threaded rod 22 rotates, the length of the threaded rod 22 extending out of the connecting tube 24 will change, thereby changing the height of the connecting tube 24, thereby achieving fine adjustment of the height of the inner sleeve 13 at the upper part of the connecting tube 24, so that the aluminum alloy plate 3 and the prefabricated floor slab 2 are more closely abutted; when the rotating rod 20 rotates, it will only drive the bearing 19 to rotate, but will not drive the mounting seat 18 to rotate, thereby utilizing the mounting seat 18 to provide stability.

[0046] In this embodiment, a bottom plate 16 is provided at the lower part of the mounting seat 18 . The bottom plate 16 is fixed to the floor through expansion bolts. Anchor holes 17 for the expansion bolts to pass through are provided on the bottom plate 16 .

[0047] In actual use, there are multiple anchor holes 17, which are arranged circumferentially along the outer side of the mounting seat 18. Expansion bolts are passed through the anchor holes 17 to fix the base plate 16 to the floor or the ground, thereby providing better support.

[0048] In this embodiment, an anti-skid cover 23 is provided on the outer side of the rotating block 21. The technician rotates the rotating block 21 through the anti-skid cover 23, which increases the friction force of the technician rotating the rotating block 21 and facilitates the operation.

[0049] When the utility model is used specifically, the aluminum alloy plate 3 is installed on the mounting plate 9, and the outer sleeve 12 is slid so that the aluminum alloy plate 3 abuts against the lower surface of the precast floor slab 2 and is located below the post-cast strip between two adjacent precast floor slabs 2. Then, the rotating block 21 is rotated to enhance the interaction force between the aluminum alloy plate 3 and the precast floor slab 2 to avoid the height of the aluminum alloy plate 3 being reduced due to the increased load when pouring concrete in the post-cast strip. Then, the nut 7 on the screw rod 5 is rotated so that the limiting steel bar 6 abuts against the upper surface of the precast floor slab 2, thereby limiting the precast floor slab 2 between the limiting steel bar 6 and the aluminum alloy plate 3. Then, concrete is poured in the post-cast strip to the designed thickness to form a cast-in-place slab 1. Then, the aluminum alloy plate 3 is removed from the lower part of the precast floor slab 2, and the screw rod 5 extending out of the cast-in-place slab 1 is cut off.

[0050] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
