LB-SP工法在防水工程中的研究、设计及应用

Study,design and application of LB-SP working method in waterproofing works

LB-SP工法是一种建筑物防水构造层次的复合工法,它是指用1～2mm厚SBS单组分橡胶防水涂料加上1.0～1.5mm氯化聚乙烯—橡胶共混卷材作为一个防水层粘结复合整体,用于屋面、地下室等防水工程的一种施工新工法。这种方法的关键点在于用SBS涂料作为防水层、卷材和基面粘结层、密封层,使涂料和卷材密封粘结在一起共同工作,充分发挥涂料和卷材的优点,弥补两者的弱点,从而使该复合防水层成为可靠、有效的防水层之一。

The LB -SP working method is a new complex waterproofing method which include1～2mm thick SBS modified asphalt single part coating and1.0～1.5mm chlorinated polyethylene -rubber mixed sheet that are bonded together and work as one.The SBS coating layer functions as waterproofing,sealing and sticking to both substrate and sheet.The method makes full use of advantages of the two materials and makes up for their disadvantages.
