Generic name: the bolt expansion sealing ring, type expansion ring, ring expansion, product type water expandable sealing ring
A product profile
In the traditional concrete wall formwork design, to pull the bolt or lath type pull rod is connected with two sets of vertical template inside and outside the main connector, due to the fixed steel template used by the tens of thousands of bolt tension because of its full-length penetrate walls, thus losing the waterproof concrete itself with the waterproof function. In order to solve this problem, currently in use in the construction is in the bolt central welding a 2-3mm thick. 80mmx80mm steel sealing plate. This method is: the quality of the weld is difficult to check and guarantee, and it is a passive waterproof once there are cracks in the weld, slag, burning, needle, and other defects, and it will be difficult to cure.
The rubber water stop sheet with PN-300 water swellable rubber made, performance reached the GB/T18173 the polymer waterproof material, the third part encounter water expansion rubber in the index. It can be round or rectangular plate and the size of the general specifications for the outer diameter size D=40mm, thickness H=10mm. When in use, as long as the water stop sleeve on the bolt or strip the middle part of the pull rod can be, was eventually buried in the cast-in-place concrete will be able to play to the best waterproof effect.
