[0037] The implementation principle of the embodiment of the application is that the plate body 1 is a waterproof plate body, the column body 2 is a column pier structure body, the column body 2 is installed on the base plate 21, a plurality of base plates 21 can be selectively inserted into the column body 2, and the column pier layout is dynamically planned, so that the structure can better adapt to complex and changeable use requirements as a whole, a plurality of column piers can more evenly disperse various loads borne by the underground garage, which is helpful to resist external forces from different directions, and if one of the column piers has a problem, the other three column piers can still maintain the stability of the waterproof plate to a certain extent, providing protection for the safety of the underground garage, and the safety and stability are stronger.

[0038] The connection of the column 2 and the base plate 21 adopts a multiple positioning and reinforcing mechanism. In the initial installation, the cooperation of the positioning column 26 and the positioning groove 27 can accurately determine the center position of the column 2 on the base plate 21, and limit the horizontal displacement of the column 2. Subsequently, the cooperation of the side block 22 and the block groove 23 and the insertion of the insertion column 24 into the column groove 25 further restricts the degree of freedom of the column 2 from multiple angles, so that the installation position of the column 2 on the base plate 21 is more accurate and stable.

[0040] When splicing the waterproof plate, the clamping strip 3 on one side of one plate body 1 is inserted into the clamping groove 32 on the clamping plate 31 on the other side of the other plate body 1. Since the cross section of the clamping strip 3 is T-shaped, the clamping groove 32 cooperates with it, so that the two plate bodies 1 can be tightly connected in the horizontal direction and are not easy to be separated. Then the sealing plate 33 on one side of the top surface of the clamping plate 31 is fixed by bolts, and the sealing block 34 on one side of the sealing plate 33 is in movable contact with the clamping strip 3, further sealing and fixing the spliced part, preventing gaps from occurring during use and causing water leakage, thereby ensuring the overall waterproof performance of the waterproof plate. The splicing method of the T-shaped clamping strip 3 and the clamping groove 32, combined with the sealing and fixing of the sealing plate 33 and the sealing block 34, makes the splicing operation of the waterproof plate relatively simple and fast. At the same time, this splicing structure can effectively prevent groundwater from seeping from the splicing gap, ensuring the overall waterproof performance of the waterproof plate.
