in step S3, the waterproof roll further includes a first external corner waterproof roll, where the first external corner waterproof roll includes a first external corner edge overlapped with the planar waterproof roll and a second external corner edge overlapped with the adjacent vertical waterproof roll, the first external corner edge is overlapped above the edge of the planar waterproof roll to form a first external corner overlapping edge, and the second external corner edge of the first external corner waterproof roll is overlapped above the edge of the vertical waterproof roll to form a second external corner overlapping edge;
further comprising step S31: at the external corner a second external corner waterproofing roll is also laid, which is laid over the corner of the planar waterproofing roll at the external corner opposite to the external corner and overlaps the first external corner edge.
2. The method for integrally laying the external corner and the internal corner of the PVC waterproof coiled material as claimed in claim 1, wherein a welding gun is used for welding the first external corner waterproof coiled material and the plane waterproof coiled material together along the overlapping edge of the first external corner; and welding the second external corner waterproof coiled material and the vertical face waterproof coiled material together along the second external corner overlapping edge by using a welding gun.
3. The method of claim 1, wherein in step S3, a rectangular first external corner waterproofing membrane is folded to form a first external corner part and a second external corner part on the left and right and a first folding mark in the middle, the first external corner waterproofing membrane is cut along the folding mark of the first external corner waterproofing membrane from bottom to top by 8-10cm, and then the first external corner waterproofing membrane is folded at a distance of 8-10cm from the lower edge to form a rectangular first external corner edge.
4. The method of claim 1, wherein in step S4, when the first external corner waterproofing roll is laid on the external corner, after the first fold of the first external corner waterproofing roll is aligned with the junction of two vertical faces of the external corner, the first external corner waterproofing roll is attached to the external corner, so that the first external corner is attached to one vertical face of the external corner, the second external corner is attached to the other vertical face of the external corner, and the edge of the first external corner is attached to the plane waterproofing roll.
5. The method of claim 1, further comprising, in step S1, starting to lay the flat waterproofing membrane by finding one side of the flat waterproofing membrane at the lowest position of the flat surface, so that the adjacent flat waterproofing membranes are overlapped, and when the adjacent flat waterproofing membranes are overlapped, the flat waterproofing membrane near the side of the lowest position of the flat surface is overlapped above the flat waterproofing membrane far from the side of the lowest position of the flat surface.
6. The method for integrally laying an external corner and an internal corner of a PVC waterproof coiled material as claimed in claim 1, wherein in step S1, the plane waterproof coiled material is formed by overlapping each other, and in step S3, the vertical waterproof coiled material is formed by overlapping each other; the distance between the longitudinal overlapping edge of the plane waterproof coiled material and the longitudinal overlapping edge of the vertical face waterproof coiled material is not less than 30 cm.
