★Construction Technology
1、Construction Procedure：
Grassroots acceptance→Construction layer to be cleaned→Configure agent (used with the configuration)→Complex parts→Waterproof layer (or gas barrier layer)→construction→test→Protective layer construction→acceptance
2、Procedures and methods of construction:
(1) Construction Quality leveling layer should be consistent with "the level of engineering and technical norms" (GB50345-2012) requirements.
(2) leveling layer should be conducive to the web development and apply paste; leveling layer should be smooth calendered, the surface smooth, clean, no cracking, Jiecha flat. Obviously does not allow sharp protrusions, dents, peeling, sand phenomenon; flatness leveling layer should be gradual change within the permissible range, slope uniform, consistent aspect, and in accordance with the requirements of design drawings.
(3) flat roof eaves, gutters, gutter and other screed slope must meet the design requirements.
(4) junction screed and facade structures (parapet, chimney, vent and Deformation, skylights wall, etc.) should be rounded to.
(5) gutter longitudinal slope should not be less than 5%, the fall-mouth around the drain should be made a little pit bottom.
(6) the choice of adhesive glue and cement 801 cement mortar <note has been made of plastic containers and tools must be clean, hard particles and impurities are not allowed into the inner plastic>. 801, plastic, water, cement volume ratio is 2: 4:10, first adhesive 801 into the prepared container, while stirring with a stirrer, water (water temperature 5 ℃ -50 ℃), water was added with stirring to 801 after glue dissolved, then added with stirring cement, cement addition is complete stir until evenly without clots, no precipitation can be used. Adhesives made should be used within four hours.
(7) waterproofing membrane adhesive and laying highlights include:
① construction conditions and preparation
Composite membrane suitable for construction temperature above 5 ℃ 25 ℃ or less carried rain prohibit construction, the construction should be prepared in case of rain waterproofing, roll after pasting prevent the wind blowing, the available heavy objects.
② leveling layer aqueous layer surface moisture content should be between 30-50%; leveling layer of cement mortar strength should reach 7.5Mpa when waterproof construction can be carried out, if too dry spray the water until qualified.
③ thoroughly cleaned screed surface while cleaning up the web site construction.
④ open web, carefully check the certificate should be retained, while the web to see if damage in transit handling.
Before
⑤ body waterproof layer construction, should be good drainage drawings more concentrated parts and additional parts of the additional layer <connection chimney and leveling layer, fall-mouth, gutters, eaves, gutters, etc.>.
⑥ Paste the web direction is determined according to drawings, drawings undetermined, free to determine the actual situation. Paste before lacing the web site in advance 3-12m, after looking in the positive direction, fixed in the middle at the beginning of the web roll to a fixed place, apply adhesive coating, and then pre-release coil rewind to Pasted good location, serials forward glue laying. The following are not allowed in the web laying rigid particles and impurities, so as not to damage the membrane. Glue laying method: First, a previously prepared with a small plastic container fell on the leveling layer at the pre-glued, rubber scraper to scrape continuous right amount to a uniform thickness should be maintained at more than 1mm, then apply no web and compacted with another blade exhaust, expel excess adhesive, construction workers should be careful, coating thickness should be uniform, the web should be firmly affixed. Without hollowing, wrinkled, paste area should reach 90%.
After construction according to GB50207-2012 "Roof Engineering Quality Acceptance" or GB50208-2011 "underground waterproof project quality inspection norms" for acceptance.
★Storage and transportation
Sheet during transportation and storage, should pay attention not to damage the packaging, placed in ventilated, dry place, storage stack height should not exceed five flat sheet roll height. When stacked, should be placed on a dry, level ground, avoid direct sunlight, NO contact with acids, alkalis, oils and organic solvents, and heat isolation.
