Description

A kind of multiple waterstop and its waterproof structure

technical field

The utility model belongs to the technical field of structure waterproofing, in particular to a waterproof product and its waterproof structure.

Background technique

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.

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.
