The waterproof work of the building is of vital importance. The waterproof work will directly affect the service life of the building. PVC PVC waterproofing membrane is a very good roofing waterproof polymer material. It is generally used in Stadiums, convention centers and other large venues in major cities. Polyvinyl chloride PVC waterproofing membrane construction precautions Precautions for the construction of polyvinyl chloride PVC waterproofing membranes 1. Consider the environment at the construction site when constructing them. The use temperature of the coils should be above -5°C. Precautions for the construction of polyvinyl chloride PVC waterproofing membranes 2. When laying the membranes for special parts, it is necessary to treat the additional layers so that they can effectively waterproof; PVC PVC waterproofing membrane construction precautions 3, to protect the construction phenomenon, before each construction is completed, the coil must be temporarily fixed, so as to avoid being blown away by the wind; Precautions for the construction of polyvinyl chloride PVC waterproofing membranes 4. The waterproof layer must be constructed in an orderly manner, and construction must not be poor. If it is necessary to install equipment on the waterproof membrane, then the basic part will be necessary. Do additional layer processing. How to install Installation Method 1. Cold Bonding Method The use of pvc coil special adhesives for the cold work to paste the film on the grassroots construction method, called cold sticking method. According to different waterproof design requirements, the cold-bonding method can be divided into full-bonded or partially bonded. (1) Full-stick method is a construction method in which all pvc coils are bonded to the base layer. 1) During the construction, the pre-paving shall be carried out first, and the PVC coiled material shall be naturally laid on the surface of the payline (not bonded first), and shall be flat and straight and shall not be twisted. 2) The web is overlapped with a width of 50mm in the longitudinal direction, and is cut appropriately. The butt joints are used in the transverse direction, on which 200-250mm wide non-composite layers (N-type) are used. The PVC web covers the overlap welding. 3) Fold the long edge of one or more webs in half (approximately 10m). Apply a special adhesive from the folds to the surface of the substrate and the web, respectively. When the glue dries until it is not sticky, pre-spread the web surface. After folding and pasting, press with a roller to compaction. Then fold the other unfolded part again, continue to operate from the folding point as described above, and then press and paste to firmly compact. Finally, the joint welding is performed. (2) Partially pasted coils. When laying on PVC coils, the coils and the base layer are glued on the base layer by sticking or sticking. Point and stick: The spot material of the coil is bonded to the base layer. Adhesion per square meter is not less than 5 points, and the area per point is 100mm×100mm. Stickiness: The coil is bonded to the base layer in strip form. Each coil has at least two bonding surfaces with the base layer, and the width of each strip is not less than 150mm. Installation Method 2. Empty Shop Method That is, when laying PVC waterproofing membranes, the coils and the ground layer are bonded only within a certain width around the entire waterproof layer; the rest of the construction method is not bonded. The construction process flow of the empty paving method is as follows: Grass-leveling leveling cleans a line of wire and a coil of material for pre-laying a coil of seam. lap welding a special part of a fixed, edge-pressing edge of a sealing material acceptance. First, the coils are pre-paved with reference to the full-stick method with a vertical lap width of 50 mm. Next, only the entire perimeter of the entire waterproofing project is fully bonded and the lap seams are welded. Horizontally using butt joints with 200 to 250 mm Wide non-composite layer (N type) PVC sheet covering overlap, welding. I believe that after reading our above article introduction, we should understand what PVC PVC waterproofing membranes need to pay attention to during construction and how to install them. Only by grasping the construction details can we better highlight the products. Superiority and usefulness. We hope that the above introduction will help everyone. |
