Hebei Factory teaches you how to correctly use back stick rubber waterstop
With the increasing demand for rubber waterstops, the application market of back attached rubber waterstops is also becoming more and more extensive. How to use rubber waterstops correctly has become an important issue. If the construction operation is improper, the rubber waterstops of the best quality will lose its role. How to use rubber waterstops rationally? If you want to know something, please follow the small editor of Hebei Tushun Rubber Products Company to have a look! If there are any more other Technical problems can be discussed in detail with our Manager Wang
Back stick rubber waterstop Natural rubber And various synthetic rubber As the main raw material, mixed with various auxiliary And filling materials, after plastic refining, mixing and pressing, have many varieties and specifications. The back stick rubber waterstop has good elasticity, wear resistance, aging resistance and tear resistance, strong adaptability to deformation and good waterproof performance.
Principle of construction and production of external (back) rubber waterstop:
In practical application, it is mainly used in deformation joints with small water pressure and deformation expansion joint , settlement joints, etc., which have the characteristics of tight anchoring with concrete, water stop sealing, and adaptation to the tensile deformation of expansion joints, etc. The back stick waterstop of the structure can also be used as a common waterstop, which can be used in the foundation engineering where the deformation joints and construction joints are integrated with the concrete structure when the concrete is poured in situ, To solve the problem of water leakage at the gap, the back stick waterstop is mainly applicable to the outside of the concrete structure floor or wall panel (concrete facing surface). It has the characteristics of tight anchoring with concrete, water sealing and elastic tensile deformation. The externally attached waterstop is a waterproof layer behind the waterproof board, which is crucial to the prevention of tunnel water seepage.
Specific construction method of external (back) rubber waterstop:
method one . On the back of waterstop 30mm The width and length of thick wood formwork shall meet the requirements of waterstop installation. The wood formwork shall be integrated with the overall formwork of the external wall to prevent displacement, slurry leakage and loss of waterstop effect of the wood formwork during concrete pouring. Simultaneous use 212in （ lin=25mm ）Double cap nails are used to fix the externally attached rubber waterstop with the wood formwork, and double cap nails are used to nail the outer edges on both sides of the waterstop 200mm Nail a double cap nail. The installed waterstop shall be flat without sagging. After pouring concrete, the strength of this part shall reach the design strength 80% The formwork can be removed above.
method two Masonry on the back of waterstop 2400mm The thick brick wall is used as the external formwork. The width and length of the brick wall shall meet the requirements for the installation of the waterstop. The brick wall shall be connected with the overall formwork of the external wall (steel formwork, bamboo formwork, etc.) to avoid mortar leakage during pouring and loss of water stop. Paste in advance inside the brick wall 3mm Thick EPDM waterproof roll or lv Butadiene rubber sheet (pasted on the plastering layer inside the brick wall, which should be firm), and then use the rubber waterstop with four hundred and one The waterproof adhesive is firmly pasted.
Application scope of back stick rubber waterstop:
External (back) rubber waterstop, as the auxiliary material of waterproof board, can be widely used for waterproofing of basement, subway tunnel, highway and * * * tunnel projects, as well as waterproofing and seepage prevention of concrete structure floor or outer side of wall board (structure facing surface) of dam, artificial lake, pool, sewage treatment plant, garbage landfill and other projects.
The above is the summary of Hebei Tushun Xiaobian based on years of construction experience of our factory's technicians. It may not be very integrated, and I hope it can help you.
