Furthermore, the number and the size of the grooves are equal to those of the bumps, so that the bumps and the grooves are matched to form the sealing wall;
further, the inner side surface of the lower layer of the second lap joint end is provided with a heating layer, the heating layer is a PET metal electric heating film, and the PET metal electric heating film can be connected with an external heating device for heating treatment.
Furthermore, the inner slope surfaces of the upper port of the second lap joint end and the lower port of the second lap joint end are provided with waterproof sealing strips, so that the sealing is carried out after the lap joint is in place.
Further, the slope angle between the slope surface and the horizontal plane is 30-60 degrees, so that the upper layer and the lower layer of the first lap joint end and the second lap joint end are better overlapped to form sealing.
Compared with the prior art, the invention has the beneficial effects that: the utility model discloses can effectually guarantee to avoid the condition emergence of the overlap joint irregularity in the course of being under construction, through the mutual matching of a plurality of recesses and lug, the effectual overlap joint effect that has prevented between coiled material and the coiled material is not good and appear scurrying water, simultaneously, lug and groove connection through the overlap joint make the overlap joint more firm, be difficult for breaking off, and the overlap joint does not have the arch, can not influence construction and aesthetic measure on next step, in addition, because the waterproof sealing strip that the slope of second overlap joint end set up, the adhesive quantity is less, the construction is more high-efficient; the practicability is strong.
