The water -stop steel plate is generally 300mm wide, and half of the new and old concrete is buried in half.The principle of function is: the location of the new and old concrete seams is called the construction seam. This belongs to the weak link of waterproof concrete and waterproof. After increasing the water and steel plate, the water can no longer go to the water -stopd steel plate along the gap in the new and old concrete stubble positions.The infiltration, the water -stop steel plate plays a role in cutting off the water penetration path.The gap penetration of the water -stop steel plate and concrete in time penetrates, and the water -stop steel plate has a certain width, which also extend the water penetration path, which can also play a waterproof effect.
Water -stop steel plate price
The price of water -stop steel plates is about 10 yuan to 26 yuan.
Welding requirements for water stop steel plate
The length of the water -stop steel plate is 50mm.The steel plate welding should be survived twice, and 2mm welded seams should be left at the joint. When the first time is cast, first welding in the middle and ends is fixed, and then welded from the middle to the upper end.After the first time, the medicine skin was knocked off immediately with a welded hammer to check whether there are sandy eyes and missing welding.The second pass should be welded from the lower end.
Standard Water Steel Specification
Article 6.1.10 of the "Construction and Acceptance Specification Specifications for Water Drainage Construction Engineering Construction and Acceptance" stipulates that the length of the metal waterproof band at the metal water stop at the construction of the structure of the structure must not be less than 20mm, and double-sided welding must be used.The process specifications of the water -stop steel plate are: 1. There is no oil on the surface of the water -stop steel plate, no obvious bending.2. The location of water -stop steel plates and buried depth must meet the requirements.If there is no requirement for the design, the position of the water -stop steel plate should be the middle position of the cross -section of the structure of the structure. The middle value of the width of the water steel plate should be built.3. The specifications of water-stop steel plates meet the requirements (generally 3㎜ thick water steel plates, width is not less than 300㎜, folded border 30-50㎜), and the overlap of two water-stop steel plates should not be less than 50mm.Fully welded.4. The reinforcement measures should be proper and firm. The welding must be full welding. The weld must not miss the welding.
Practice of water -stop steel plates
1. Water -stop steel plate installation is fixed with steel bars.Welded the steel plate supporting rack on the structural reinforcement, and the supporting rack is welded after cutting the steel bar of φ12. Generally, it is welded into a triangle to support the bottom plate and the top plate.The supporting rack and the main tendon welding, the steel plate and the supporting frame welding, the wall of the wall is a steel plate, the steel plate is welded at the bottom of the steel plate to support the steel bars, and then the support frame is located.The specifications and material performance of the welding stripes should meet the design requirements.2. The centerline of the steel plate is overlapped with the construction sewing, installed on the 1/2 plate (wall) thick, and half of the concrete and rear concrete are poured first to ensure the horizontal and verticality of the steel plate.3. Galvanized steel plate stops the tour of the tour of the tour of the tour of the tail -tailed direction as: top and bottom plate swallow tails facing up, the horizontal construction seam of the side wall is facing the back of the back water, and the vertical construction seam of the side wall faces the water side.
