Waterproof structure of prefabricated external wall panel
The invention provides a waterproof structure of a prefabricated external wall panel. The waterproof structure comprises a left prefabricated wall panel component, a right prefabricated wall panel component, an upper prefabricated wall panel component and a lower prefabricated wall panel component; a horizontal splicing seam is in a tongue-and-groove shape with a high inner part and a low outer part; a joint material, a rubber airtight strip, a first pressure reduction cavity, a first polyethylene rod and a first sealant are sequentially arranged on a vertical splicing seam from the indoor side to the outdoor side; and the first pressure reduction cavity comprises a first cavity and a second cavity which are in communication with each other, the polyethylene rod is located between the first cavity and the sealant, and the rubber airtight strip is located between the second cavity and the joint material. According to the waterproof structure of the prefabricated external wall panel, the pressure reduction cavity is formed in the splicing seam, water flow is prevented from seeping into a room through the pressure difference between the pressure reduction cavity and the external air pressure, the waterproof effect is enhanced on the basis of self-waterproofing of the structure, moreover, even if a local water seepage phenomenon occurs, the water can be drained to the outside through the reserved cavity, so that the later maintenance cost is reduced.
本申请提供一种预制外墙板的防水结构，包括：左预制墙板构件、右预制墙板构件、上预制墙板构件和下预制墙板构件；水平拼接缝采用内高外低的企口形状；竖直拼接缝由室内侧至室外侧依次设置有接缝材、橡胶气密条、第一减压空腔、第一聚乙烯棒和第一密封胶；其中，第一减压空腔包括相互连通的第一腔室和第二腔室，聚乙烯棒位于第一腔室与密封胶之间，橡胶气密条位于第二腔室与接缝材之间。在本申请提供的预制外墙板的防水结构中，通过在拼接缝中设置减压空腔，并利用减压空腔与外部气压之间的压力差防止水流渗入室内，在结构自防水的基础上增强了防水效果，而且，即使出现局部渗水现象也能够通过预留的空腔引流至室外，由此减少后期维护成本。
