Scope of application (1) this recommendation is applicable to new, expanded or renovated roofing waterproofing works. Construction of 1-4 class durable years specified in ministerial standards (see table 1). (2) in recent years, the development new waterproof materials, waterproof construction processes were changed, roofing felt waterproofing construction in addition to using common linoleum thermal bonding process, various new coil used in roof of cold sticking method, melt method, since the glue method technology has been used for many years, It has some advanced nature, scientific and practical. Will now can use a new type of asphalt waterproof coiled material roofing waterproof engineering, polymer modified asphalt waterproofing materials, synthetic polymer waterproof coiled material roofing waterproof coiled material is much more mature and reliable, recommended for design and construction personnel, for your selection. Ii. Basic requirements of design (a) roof engineering according to the nature of the building, importance, function requirements, building structure and waterproof durability, etc., the waterproofing roof is divided into four grades, and according to the different levels of security (see chart 2). (2) the new waterproof rolling materials adopted in the design of the recommended practice shall be strictly constructed according to the technical requirements of the rolling materials. (3) the roofing and the roofing. The person roofing according to the design person chooses cement sand mortar, floor tile and so on protective layer. Do not have a person's roofing should make protective layer, such as brushs reflective paint, cover coarse sand, green bean stone and so on. (4) the drainage slope of the flat roof is 2%, the drainage slope of the outer cornice is greater than 1%, the drainage slope of the water outlet is 3 ~ 5%, and the slope of the roof of the person's roof should be 2%. (5) there are four methods for rolling stock. 1. Hot melt method: refers to the hot melt adhesive which is used to melt the bottom of the waterproof rolling material by using the heater. The method to realize the bonding between the coil and the base is called the hot melt method. 2. Cold bonding method: refers to the method of using cementing material to directly realize the bonding of the waterproof rolling material with the base. 3. Self-adhesive method: refers to the use of waterproof rolling materials with self-adhesive adhesive, which do not require thermal processing, and do not need to be coated with other materials, and the method of directly implementing the water-proof rolling materials and the base bond is called self-adhesive method. 4. Hot asphalt method: refers to the method of using hot bituminous cementing material to realize the waterproofing rolling materials directly with the base bond. (6) roof rolls are constructed according to the construction process, which can be used in the construction of a full paste, stick, stick, and empty shop. When placing the tiling, the air under the coil should be discharged at the same time, the coil shall be smooth and solid, and the joints must be full of adhesion and tight joints. 1. Full adhesion: the construction method for the adhesive construction of the whole area of the rolling material and the base area when the waterproof rolling material is covered. 2. Adhesive: when the waterproof rolling materials are covered, the rolling materials and the grass roots only make the construction method with adhesive. That is to make a band of 200 ~ 250mm in the width of the coil. The slime is also known as a strip method, with a bond area of no less than 25%. 3. Sticky-stick: the construction method of only point bonding with the base at the base of the waterproof rolling material is also called the flower shop method. The total area of bond is 6%, Each square metre is bonded to 5 points, each area is 100 x 100mm. 4. Empty shop: when it is covered with waterproof rolling materials, the coil shall be bonded to the base only in a certain width, and the rest shall not be bonded. (7) roofing waterproofing shall be constructed according to the design materials and construction requirements. General roof coil shall be determined according to the slope and roof of the roof. When the roof slope is less than 3 %, the roll shall be covered by parallel roof. When the roof slope is 3 % ~ 15 %, the roller can be parallel or vertical roof. The roof slope is greater than 15% or the roof of the roof is affected by the vibration of the vertical roof, the upper and lower rolling materials may not be perpendicular to each other. When the slope is more than 25%, it is not suitable to make the coil waterproof. (8) the width of the coil width shall be in accordance with table 3 requirements. (9) it must be treated with additional layer of water, such as yin-yang Angle, tube root and water outlet.
