Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a waterproof board for building construction comprises a plastic base plate 1 supported and mounted with a construction structure and a waterproof convex shell 2 in an upper arc shape and integrated with the plastic base plate 1, wherein the waterproof convex shell 2 is integrally arranged at the end of the plastic base plate 1 at equal intervals, and the bottom of the waterproof convex shell 2 is integrally provided with an inclined branch 3;

two ends of the waterproof convex shell 2 are provided with concrete flowing edges 4 which are inclined inwards;

the concrete layer 5 is poured outside the waterproof convex shell 2 and the plastic substrate 1, and concrete constructed by the concrete layer 5 flows into the waterproof convex shell 2 through the concrete flowing edge 4 and is closely fixed between the waterproof convex shell 2 and the plastic substrate 1.
