    • A roof tile construction includes a ventilation tile having pliable portions provided by a membrane of PVC (polyvinyl chloride) which is readily deformable to complement the shapes and configurations of adjacent roof tiles, whereby gaps between the headlap, side-lock and tail portions of tiles immediately adjacent the ventilation tile are substantially closed. The ventilation tile also includes a rigid body portion for supporting the membrane, the body portion being generally of planar configuration and being provided with adapter means for accommodating ventilation means such as a ventilation cap, or a soil pipe. The membrane is also of generally planar configuration and includes a headlap portion, oppositely disposed side-lock portions and a tail portion which extends beyond the rigid body portion. The tail portion is provided with an adhesive coating and with stiffening means in order to secure the tail portion to and maintain conformity of the tail portion with the profile of the headlap portion of an adjacent tile, and is also provided with corrugations extending across the width thereof. A depending wall portion at the headlap portion of the rigid body portion assists in locating the ventilation tile on a roof batten.
    • 屋顶瓦结构包括具有由PVC(聚氯乙烯)膜提供的柔韧部分的通气瓦,其易于变形以补充相邻屋顶瓦的形状和构造,由此,瓦片,侧锁和瓦片的尾部之间的间隙 紧邻通风瓦片基本上封闭。 通气瓦还包括用于支撑膜的刚体部分,主体部分大致为平面构造,并且设置有用于容纳诸如通气盖或土壤管道的通风装置的适配器装置。 膜还具有大致平坦的构造,并且包括头部部分,相对设置的侧面锁定部分和延伸超出刚体部分的尾部部分。 尾部设置有粘合剂涂层和加强装置,以便将尾部部分固定并保持尾部与相邻瓦片的头皮部分的轮廓的一致性,并且还设置有跨越宽度的波纹 其中。 在刚体部分的头皮部分处的悬垂壁部分有助于将通气瓦片定位在屋顶板条上。
