Rear-mounted semi-self-adhesive cross-shaped middle-buried waterstop structure

The utility model discloses a rear-mounted semi-self-adhesive cross-shaped middle-buried water stop belt structure which comprises a main belt body, the main belt body is in a cross shape, a plurality of cavities are formed in the middle of the main belt body, and separation seams are formed between the cavities. The middle-buried water-stop belt has the advantages that the main belt body is in the cross shape and is provided with the cavities, the separation seams are arranged between the cavities, and therefore the stretching and compression deformation capacity of the middle-buried water-stop belt is improved, and when the main belt body deforms oppositely or deforms in a separated mode, the middle-buried water-stop belt has the self-water-closing function, and water seepage is avoided. 本实用新型公开了一种后安装的半自粘十字形中埋止水带结构，包括主带体，主带体呈"十"字型，且主带体中部开设有若干空腔，且每个空腔之间设置有分离缝。本实用新型的有益效果是：主带体呈"十"字型，并且设置有空腔，每个空腔之间设置有分离缝，从而提高了中埋止水带拉伸、压缩变形的能力，且主带体发生相向变形或分离变形时，均具有自闭水功能，避免渗水。
