PVC boards shall be qualified products meeting environmental protection requirements, and product performance test reports, ex factory quality certificates and product specifications shall be provided in a timely manner. Plastic welding rods shall be provided by PVC suppliers with triangular or circular plastic welding rods, whose thickness, color and performance shall be the same as those of plates, and product quality certificates and construction instructions shall be submitted.
PVC board is usually laid on cement mortar or concrete base. In order to ensure the laying quality of the plastic floor, the gap between the plate surface and the base course shall be reduced as far as possible. The residual mud, dust, soil and sand on the base course surface shall be cleaned and wiped with a wet cloth.
When laying PVC plates, the sump of the water storage tank shall be laid first. There are many welds here. PVC welding rods of the same specification shall be used for steel welding. Before laying, it should be noted that there is no water at the bottom of the well. Before setting out, measure the actual size of the sump, and reduce the welds as much as possible.
After the details of the sump are laid and welded, they can be laid from the bottom plate to the top of the pool wall. PVC is laid in a whole roll and laid horizontally along the longitudinal direction of the swimming pool. First, press one end of PVC onto the top surface of the pool wall with 80mm 80mm PVC plate and expansion bolt, and then lay it flat on the bottom of the pool. It shall be paved to the top surface of the pool wall at the other end along the longitudinal straight line, and the return edge shall be flush with the outer wall of the top surface. The paved PVC push plate shall be flattened with rubber roller. After expansion, the other end of PVC is compressed with an 80 mm 80 mm PVC and an expansion bolt. When the second row of PVC is spread longitudinally, a 50mm lap joint shall be reserved with the first row. When the joint is overlapped, the second row of PVC shall be flat. After overlapped with the first row, it shall be evenly compacted and leveled with a rubber roller. One person shall level before the other person and weld after the other. While welding, leveling shall be carried out. At the same time, it shall be timely checked that there is no bulge in the fusion joint, and the fusion degree of the fusion joint shall be checked.
