Telescopic pull-crack-preventing water stop belt and using method thereof

ZHAO PENGFEI / LUO ZHONGPING

The invention belongs to the technical field of building construction, and particularly discloses a telescopic anti-pull-crack water-stop belt which comprises a middle water-stop belt, side water-stop belts, a telescopic structure, a shaping structure and an anti-tearing structure. Side edge water-stop belts are arranged on the two sides of the middle water-stop belt; telescopic structures are arranged between the middle water-stop belt and the side water-stop belts, and anti-tearing structures are detachably arranged at the two ends of the side water-stop belts. And shaping structures are arranged between the two ends of the middle water stop belt and the corresponding anti-tearing structures. The telescopic structure comprises a folding telescopic belt; cavities are formed in the two sides of the middle water stop belt correspondingly, and folding telescopic belts are connected to the upper sides and the lower sides in the cavities correspondingly. Through the arrangement of the telescopic structure, when the two sides of the deformation joint displace, the folding telescopic belt deforms, and the folding telescopic belt is pulled outwards to be flat, the pull crack resisting effect is achieved, so that the flexibility of the water stop belt is effectively guaranteed, the service life of the water stop belt is prolonged, and meanwhile the water stop effect of the water stop belt is guaranteed.

本发明属于建筑施工技术领域，具体公开一种可伸缩防拉裂的止水带，包括中部止水带、侧边止水带、伸缩结构、定型结构和防撕裂结构；中部止水带两侧均设置有侧边止水带；中部止水带和侧边止水带之间均设置有伸缩结构，侧边止水带的两端均可拆卸的设置有防撕裂结构；中部止水带的两端和对应的防撕裂结构之间均设置有定型结构。伸缩结构包括折叠伸缩带；中部止水带两侧均设置有空腔，且空腔内上下两侧皆连接有折叠伸缩带。本发明通过伸缩结构的设置，当变形缝两侧产生位移，折叠伸缩带产生形变，将折叠伸缩带向外拉平，达到了抗拉裂的效果，从而有效保证了止水带的伸缩性，延长了止水带的使用寿命，并同时保证了止水带的止水效果。
