Referring to fig. 3 and 4, the steps of construction of the S6 roof waterproof layer include:
s61, preparing a coiled material: cutting the coiled material 6 for later use according to the paving length by adopting a 3 mm-thick SBS modified asphalt waterproof coiled material (II type) +4.0-thick SBS modified asphalt root-penetration-resistant waterproof coiled material;
s62, paving coiled materials: the end of the coiled material 6 is compared with the starting point of the flat paving, the blast lamp is debugged to be ready, then the interface between the coiled material 6 and the substrate (the distance between the blast lamp and the coiled material 6 is kept about 0.3 m), when the hot melt adhesive on the surface of the coiled material 6 is melted and black gloss is generated, rolling and pasting are carried out, the air below the coiled material should be removed when rolling and pasting is carried out, so that the coiled material is flat, the wrinkles are reduced, the coiled material is firmly pasted, the force is required to be uniform, and no air is generated; when the waterproof SBS coiled material 6 is paved and lapped, the length direction and the short direction are both more than or equal to 1 mm, the waterproof construction method of the top plate is that the joint of the coiled material 6 is heated by a blast lamp until the edge is extruded and firmly stuck. The upper and lower coiled materials 6 must not be vertically paved, and the lap joint of the upper and lower coiled materials 6 and the adjacent coiled materials should be 1/3 of the width.
