[0028] When in use, first install the composite board body 2 on the left and right sides of the mounting plate 1 by pressing the fixing assembly 3, and tightly install the pressing and fixing assembly 3 and the composite board body 2. Then set the utility model at the place of use, and then pour concrete on the mounting plate 1 until the concrete is level with the upper end of the composite board body 2, thereby reducing the contact area between the concrete and the side of the composite board body 2, so that the composite board body 2 will not be squeezed when the concrete expands, thereby reducing concrete leakage.
[0029] In addition, the pad 4 is U-shaped, and the U-shaped opening of the pad 4 is set toward the mounting plate 1. The U-shaped structure of the pad 4 allows concrete to enter the interior of the pad 4, thereby reducing the squeezing and pressing of the fixing component 3 and the composite plate body 2 when the concrete expands, thereby reducing the leakage of concrete.
[0030] like Figure 4 and Figure 5 As shown, the pressing and fixing assembly 3 includes a lifting plate 301, which is evenly fixedly installed on both sides of the upper end of the mounting plate 1, and a lifting groove 302 is provided on the upper end of the lifting plate 301, and the upper end of the lifting groove 302 extends to the upper part of the outer part of the lifting plate 301, and a lifting block 303 is slidably installed in the lifting groove 302, and a threaded hole 304 is provided in the lifting block 303, and a lifting screw 305 is threadedly installed in the threaded hole 304, and the lower end of the lifting screw 305 extends to the lower part of the outer part of the mounting plate 1, and the lower end of the lifting screw 305 is located at the lower end of the outer part of the mounting plate 1, and the lifting screw 305 can be rotated by a tool such as a screwdriver through the lower end.

[0031] When in use, first place the composite board body 2 between the pressing plate 306 and the pad 4, then rotate the lifting screw 305 to make the lifting block 303 rise and fall in the lifting groove 302, so that the fixing column 307 is clamped in the fixing hole 7, and at the same time, the composite board body 2 can be pressed by the pressing plate 306 to fix it, so that the composite board body 2 can be isolated when pouring concrete to prevent the concrete from expanding and squeezing the composite board body 2, causing concrete leakage.
[0032] like Figure 6 As shown, the reinforcing assembly 6 includes a clamping rod 601, the clamping rod 601 is located on one side of the fixing plate 5, and reinforcing steel bars 602 are evenly fixedly installed between the clamping rods 601, and clamping holes 603 are opened at both ends of one side of the clamping rod 601, and mounting holes 8 are evenly opened at both ends of the fixing plate 5.

[0034] When in use, first place the composite plate body 2 between the pressing plate 306 and the pad 4, then rotate the lifting screw 305 to make the lifting block 303 rise and fall in the lifting groove 302, so that the fixing column 307 is clamped in the fixing hole 7, and at the same time, the composite plate body 2 can be pressed by the pressing plate 306 to fix it, so that the composite plate body 2 can be isolated when pouring concrete to prevent the expansion of the concrete from squeezing the composite plate body 2 and causing leakage of the concrete. The reinforcing component 6 is poured in the concrete, so that the strength of the concrete can be improved. At the same time, the height of the reinforcing component 6 can be adjusted by adjusting the height of the fixing bolt 9 and the clamping rod 601, which is convenient for the user to adjust.
