Construction method:
Waterproof construction should be carried out after the completion of masonry, equipment installation and pipeline. The junction of coiled material waterproof layer and protruding roof should be arc-shaped. Arc radius: 50mm for modified asphalt and 20mm for synthetic polymer. Make a pit with a slope of not less than 5% within 500mm around the water outlet, and coat it with waterproof coating with a thickness of not less than 2mm; Impinges contact with the grassroots, leaving a groove with a width of 20mm and a depth of 20mm, and filling in the sealing material. The ends of the coiled materials in the gutter, eaves gutter and floodplain should be cut, and the coiled materials should be laid on the roof and covered with metal or reinforced concrete. The leveling layer around the pipeline protruding from the roof should be made into a cone shape, and a groove is left between the pipeline and the leveling layer and filled with dense materials; Metal hoop is used for waterproof sealing and filled with sealing material. The shape of tile roof and protruding roof, gable, skylight, high-low span junction, chimney, exhaust pipe, etc. should be flooded and waterproof layer should be added. Requirements for relevant dimensions of tile roof: ① The length of tile extending into gutter and eaves gutter is 50-70 mm; (2) The length of the wall protruding from the roof or the side tile of the chimney extending into the floodwater shall not be less than 50mm(3) The structure protruding from the surface of the ceramic tile shall be made with waterproof mortar not less than 30mm on the water surface; (4) The lap joint on both sides of the ridge tile shall not be less than 40 mm The roof shall be tested by spraying water or storing water.
Precautions:
All cuts and seams should be bonded and sealed with Toyo brand special glue. After installation, all tees, elbows, valves, flanges and other accessories should reach the design thickness. Don't use too much force when bonding with glue, and the interface between all materials should be bonded under slight extrusion. During installation, large pipes should be followed by small pipes, elbows and tees should be followed by straight pipes, and valves and flanges should be followed. When installing chilled water pipes and refrigeration equipment, the gaps at both ends of rubber-plastic pipes and iron pipes should be coated with glue, and the bonding width should not be equal to the thickness of rubber-plastic materials. The cuts of pipes should be installed in inconspicuous places as far as possible, and the cuts of two pipes should be staggered. Do not install the machine in use. Do not turn on the machine within 36 hours after installation. Large-diameter rubber-plastic pipe has become oval due to packaging. Please cut the flat side when cutting.
