Description
技术领域 technical field
本实用新型属于结构防水技术领域,具体涉及一种防水产品及其防水结构。 The utility model belongs to the technical field of structure waterproofing, in particular to a waterproof product and its waterproof structure.
背景技术 Background technique
随着城市建筑物规模不断的增加和抗震技术的不断发展,越来越多的高低建筑物连成一个整体,形成错落有致的建筑美感,同时也会给房屋建筑带来由于高度差异所导致的差异沉降等安全隐患,如果在施工过程中不能很好的解决这些隐患,极有可能造成结构裂缝甚至破坏。为了解决上述问题,目前通常的做法是从基础到墙体均设置预留的后浇带或者沉降缝,待两侧的高低建筑物沉降稳定之后浇筑后浇缝混凝土。 With the continuous increase in the scale of urban buildings and the continuous development of anti-seismic technology, more and more high and low buildings are connected into a whole, forming a well-proportioned architectural aesthetic, and at the same time, it will also bring the buildings due to height differences. Potential safety hazards such as differential settlement, if these hidden dangers are not well resolved during the construction process, it is very likely to cause structural cracks or even damage. In order to solve the above problems, the current common practice is to set reserved post-casting belts or settlement joints from the foundation to the wall, and pour the post-casting concrete after the settlement of the high and low buildings on both sides is stable.
目前后浇带或者沉降缝处为了防水构造的通常是在后浇带或者沉降缝内直接填塞止水条。但是后浇混凝土水化收缩后,后浇混凝土与先浇筑混凝土之间不可避免的会出现大于止水条的缝隙,因此在实际工程中这种填塞止水条的办法经常丧失此种构造的止水作用。还可以在后浇带或沉降缝处放置止水带,止水带与混凝土之间由于材料结合不紧密,通过后浇带或沉降缝向上渗水的现象也十分普遍。 At present, the post-cast belt or settlement joint is usually directly filled with water-stop strips in the post-cast belt or settlement joint for waterproof construction. However, after the post-cast concrete hydrates and shrinks, there will inevitably be a gap larger than the water-stop strip between the post-cast concrete and the first-cast concrete. water action. It is also possible to place a water stop at the post-pouring belt or settlement joint. Due to the lack of tight material bonding between the water-stop belt and the concrete, it is also very common for water to seep upward through the post-pouring belt or settlement joint.
