Prefabricated building laminated slab abutted seam mortar leakage prevention structure
The invention discloses a prefabricated building laminated slab abutted seam mortar leakage prevention structure. An abutted seam is formed between two laminated slabs. The prefabricated building laminated slab abutted seam mortar leakage prevention structure comprises a supporting formwork, a caulking plate and a foam adhesive tape, the supporting formwork is arranged at a lower end opening of the abutted seam in a blocking mode, and the two opposite sides of the supporting formwork are correspondingly in lap joint with the two laminated slabs; the caulking plate is arranged in the abutted seam and laid on the inner side of the supporting formwork, and a miniature gap is formed between the caulking plate and the two opposite side walls of the abutted seam; the foam adhesive tape is bonded to the inner side of the supporting formwork, the foam adhesive tape is arranged in the length direction of a micro-shrinkage gap, the foam adhesive tape is provided with a first side and a second side which are opposite, the first side of the foam adhesive tape is arranged between the supporting formwork and the laminated slabs in a cushioned mode, and the second side of the foam adhesive tape extends to the micro-shrinkage gap and is filled in the micro-shrinkage gap. The problems that when an uneven aluminum alloy formwork is adopted for fixing and plugging at the joint of the prefabricated building laminated slab, grout leaks when concrete is poured at the joint of the laminated slab, and the concrete forming quality is poor are solved.
本发明公开了一种装配式建筑叠合板拼缝防漏浆结构，两叠合板之间形成拼接缝，该结构包括：支承模板，封堵于拼接缝的下端口，支承模板的相对两侧分别搭接于两叠合板；设置于拼接缝中的嵌缝板，铺设于支承模板的内侧，嵌缝板与拼接缝的相对的两侧壁之间形成微缩间隙；以及泡棉胶带，粘接于支承模板的内侧，泡棉胶带沿微缩间隙的长度方向设置，泡棉胶带具有相对的第一侧和第二侧，泡棉胶带的第一侧垫设于支承模板和叠合板之间，泡棉胶带的第二侧延伸至微缩间隙且填充于微缩间隙中。本发明解决了装配式建筑叠合板拼缝连接处采用不平整的铝合金模板进行固定和封堵时，导致叠合板拼缝连接处的混凝土浇筑时漏浆，混凝土成型质量差的问题。
