Further, the fixed knot constructs including the dovetailed clip and its outside nut, the dovetailed clip inboard with enclose the purlin card and fasten through the nut.
Further, the water stopping part is a square or round water stopping gasket with a hole in the middle.
Furthermore, the cushion block is a round plug made of a bamboo plywood.
The utility model has the advantages and technical effects that:
the utility model has simple structure, can be manufactured by using the existing materials of the construction site, and the water stop gasket is welded in the middle of the screw body, so that the water seepage path is enlarged, and the water stop effect is ensured; manufacturing two-side round cushion block plugs by using bamboo plywood scraps and waste bamboo plywood, and positioning by a segmented screw main body to prevent cushion blocks from moving in the concrete pouring process; the outer side is fixed by using a dovetail clamp and a screw cap, so that the detachable screw cap is convenient to process and reduces environmental pollution.
