1、满贴法又称全粘法,是一种传统的施工方法,适用于屋面结构变形不大,屋面面积较小且基层较干燥的条件。其优点在于因为有了一定的胶结材料,所以整体防水性能好。但若找平层湿度较大或赋予面变形较大时,防水层易起鼓、开裂。
Full-paste method, also known as whole stick method, is a traditional construction methods, structural deformation is not applicable to the roof, the roof area is small and grassroots drier conditions. The advantage is that because of some cementing material, so overall good waterproof performance. But if screed humidity or given surface deformation is large, waterproof layer easy to play drums, cracking.
2、空铺法指卷材与基层仅在四周一定宽度内粘贴,其余部分不粘贴。适用于基层潮湿,而保温层和找平层干燥有困难时的屋面,或用于埋压法施工的屋面,沿海地区不宜。其优点是能减少基层变形对防水层的影响,有利于解决防水层起皱、开裂问题。但因为缺少粘结,防水性能降低,不易找到漏点。
Empty shop law refers paste with the primary coil only within certain width around the rest is not pasted. Suitable for damp grass, while leveling layer insulation layer and dry when there are difficulties in the roof, or to bury construction method of the roof, coastal areas should not be. Its primary advantage is to reduce the impact of deformation on the waterproof layer, waterproof layer is conducive to resolving wrinkling, cracking problem. But because of the lack of bonding, waterproof performance degradation, easy to find the leak.
3、条粘法是卷材与基层采用条状黏结,每幅卷材与基层粘贴面不少于2条,每条宽度不少于150mm,卷材与卷材搭接应满粘,叠层铺也应满粘,其优点是由于卷材与基屋有一部分不黏结,故增大了防水层适应基层的变形能力,有利于防止卷材起鼓、开裂。其缺点是操作比较复杂,部分地方能减少一油,影响防水功能。
Article stick method is the use of a strip bond with the primary coil, roll each piece of adhesive surface with the grass roots of not less than two, each width of less than 150mm, coil and sheet lap should be full of sticky, laminated shop also should be fully adhered, the advantage is due to the membrane and the base part of the house there is no bond, it increases the waterproof layer deformation capacity to adapt to the grass roots, and prevent the coil from the dark, cracking. The disadvantage is that the operation is more complex, some parts can reduce an oil, affecting the waterproof function.
4、点粘法是指卷材与基层采用点黏结,要求每平米至少有5个黏结点,卷材搭接处应满粘,防水层周边一定范围内也应与基层满粘。适用于留槽排汽不能可靠地解决防水层开裂和起鼓的无保温层屋面,或温差大,基层潮湿的排汽屋面。其优点是增大了防水层适应基层变形的能力,有利于解决防水层起皱、开裂问题。但是仅可用于卷材多叠层铺贴施工,操作比较复杂。
Point stick method is the use of point of bonding with the primary coil, requiring at least 5 per square meter bonding points should be fully adhered membrane lap, they should stick with the grassroots full waterproof layer surrounding a certain range. Apply to stay tank exhaust waterproof layer can not be reliably resolved without cracking and played drums roofing insulation, or the temperature difference between the exhaust damp grass roof. The advantage is the ability to adapt to increased grassroots waterproof layer deformation conducive to resolving the waterproof layer
wrinkling, cracking problem. But only available for multi-laminated membrane paving construction, operation is relatively complex.
