Application of water-stop steel plates and the importance of water-stop steel plates

When pouring the upper layer of concrete with the water-stop steel plate, a layer of cement mortar was not laid at the construction joint first, and the upper and lower concrete layers of the butterfly buckle could not be firmly bonded. The construction joints should be set up in strict accordance with the regulations and should be taken seriously to avoid improper positioning or improper handling. To prevent quality accidents, to ensure structural safety and service life, for one-way slabs, construction joints should be left at any position parallel to the short side of the slab. Floor slabs with primary and secondary beams should be poured in the direction of the secondary beams, and construction joints should be left in place. Within the middle 1/3 of the secondary beam span, it can also be left at the intersection of longitudinal and transverse walls.
The construction quality of water-stop steel plates is to regulate the distance from the center height to the foundation floor surface should be greater than or equal to 250mm. In order to facilitate construction, the width is processed to 300mm and the length is 3m, so there is a relatively generous progress space.
 After determining the horizontal elevation of the steel plate waterstop, a line should be drawn at the upper end of the steel plate waterstop according to the elevation control point of the building to keep its upper end straight. If it is a shear wall, it should be installed at the center line of the wall, and the top and bottom must be vertical.
 When installing the steel plate waterstop, 10-15cm of the steel plate is exposed. When pouring concrete next time, pour this part of the steel plate together to prevent the penetration of pressure water from the outside.
  Externally attached water-stopping steel plates are used for water-stopping construction of deformation joints and expansion joints. According to their construction methods, they are also called back-attached type. This kind of water stop is made of rubber and other plastic materials. It is mainly based on the elasticity and flexibility of the material and closely fits the gap. When it encounters water, it will expand and deform, which is very good at blocking gaps. It can achieve the purpose of sealing and blocking water leakage into the wall. The material of the externally attached waterstop itself is flexible, so special attention must be paid to ensuring its straightness during installation and construction. Once misunderstood, it will directly affect the water blocking effect, so it is recommended to tie it with a tie to ensure that it will not move. , which saves effort when backfilling.
Classification and common specifications of water-stop steel plates. Water-stop steel plates can be mainly divided into: ordinary steel plate waterstops, galvanized steel plate waterstops, stainless steel plate waterstops. The specifications are: 200*2, 200*3, 300*2, 300*3, 350*2, 350*3, 400*4, 330*5 and other specifications. Can be customized according to user requirements. Each section is usually processed into ≤2m for ease of operation. During construction, attention should be paid to overlapping, the weld surface should be welded well, and the corners should be handled reasonably. A good steel plate water stop should be firmly fixed with the steel bars of the wall (or plate) . The steel plate should be straight and not twisted. Caution should be exercised if steel plate waterstops are used in horizontal joint construction.
Therefore, in the future market competition, we should have a clear and clear understanding of the development trend of the construction industry. After all, in the complex real environment, only by gradually expanding the application of water-stop steel plates can more and more people Many construction projects improve the level of waterproofing. It is precisely because of the continuous formation of these objective factors that the development level of the entire industry has been greatly improved.
Everyone can imagine the future of water-stop steel plates. It has so many advantages and has attracted attention all over the world. Water-stop steel plates are not only developing well in China. Society is constantly progressing. Water-stop steel plates We are also making continuous progress to meet human needs. In the future, water-stop steel plates will have more advantages and will be used in more and more industries. Water-stop steel plates will become an indispensable material for us and slowly become popular all over the world. front end.
