Water stop screw and ordinary bolts are the same as building bolts, they are used for formwork reinforcement, can form an aspect of the shear wall after construction, the so-called ordinary bolts, refers to the ordinary concrete wall with formwork reinforcement, whether wood formwork or aluminum formwork, but reinforcement auxiliary pouring, here we can define the ordinary bolt for the pull bolt, can be reused, but does not have other functions For example, waterproof like a water stop screw. The water stop screw is not the same, it is used for the formwork of waterproof concrete and the reinforcement of shear walls with waterproof requirements. It is a consumable material, so the algorithm of the water stop screw should find Party A to do the visa, and it is better to calculate according to the root. The ordinary bolts are included in the template turnover material, and there is no need to calculate the cost.
Ordinary bolts are wall bolts and pull bolts, just a section of tie rod type, which belongs to the double-headed bolt or wire bolt without water stop sheet. This bolt can be reused in construction, and the template can be used to build the poured concrete wall to ensure the completion of the wall pouring, and then the hole sealing is completed after construction. Assume that welding a water stop sheet in the middle of the ordinary bolt, or welding three water stop sheet process requirements, play the effect of water stop and waterproof deformation into a water stop screw, it is the same as the ordinary bolt to build the template, for more than a water stop role, in the construction node, do a good job of sealing, do a good job of additional waterproof layer, the two node sealing is roughly similar.
