摘　　要：预制混凝土外墙板的防水措施按原理可分为材料防水(密封防水)和构造防水(排水)两大类。材料防水是依靠防水材料阻断水的通路,达到防水的目的,如接缝嵌填耐候建筑密封胶、外挂墙板周边设置橡胶空心气密条等;构造防水是采取合适的构造形式阻断水的通路,以达到防水的目的,如采用外低内高企口缝、设置排水空腔构造等。By principles, waterproofing measures for pre-fabricated concrete external walls can be divided into two types：material waterproof（sealing） and structure waterproofing（draining）. The former＇s waterproofing target is realized through cutting off water＇s passage by waterproofing material, for example： filling the joints with weather-proof building sealant,setting hollow rubber airtight strip around external wall panels et cetera; while the latter, i.e. structure waterproofing, achieves its waterproofing goal through blocking water passage with proper structures, like tongue and groove joint of which outside part is lower and inside part is higher, setting drain cavum structure etc.
