More optionally, a plurality of wing plate waterproof strips are arranged on two sides of the water stop strip.
More optionally, the tail end of the wing plate waterproof strip is provided with a tail fin with a width larger than that of the wing plate waterproof strip.
Preferably, the left side and the right side of the wing plate waterproof strip extend to form a plurality of wing claws.
By the above-mentioned the technical scheme of the utility model can see out, the utility model discloses following technological effect has:
the utility model discloses a tip at the stagnant water strip of waterstop structure is provided with the fin, can prevent that it from contracting to warp to can reduce the influence to the stagnant water effect, can improve the stagnant water effect from this.
The utility model discloses set out from the stagnant water principle of waterstop structure, through improving its structure, make its stagnant water strip both sides be equipped with the pterygoid lamina waterproof strip respectively to can prolong the rivers return circuit, bury the stagnant water ability in the waterstop structure in improving.
The utility model discloses a wing claw extends out in the both sides of the waterproof strip of pterygoid lamina to can further prolong the rivers return circuit, bury the stagnant water ability of waterstop structure in improving.
