Supply: step by step tight sealing of high-strength steel screw shut net mountain-type card Sealing sealing screw high-strength steel screw sealing principle is: the old and new concrete construction joints called joint position, this belongs to waterproof concrete waterproof weakness, increasing After sealing plate, sealing plate when the water ran along the slit position of penetration Jiecha old concrete that is unable to go down to seepage, sealing plate has played a role in cutting off water penetration path. Along the sealing plate and the gap in time between the penetration of concrete, sealing plate with a width, but also extend the water infiltration route, can also play the role of water. Sealing plate construction methods and procedures: the need to seal the floor plate steel linked plate steel in the construction, can be made of 12 # steel gate-shaped bracket to the base plate steel top, between the use of the gantry and the sealing plate welding, concrete steps are as follows: 1, the first two 12 # steel perpendicular to the base plate is fixed, the sealing plate placed in the middle of two bars, reinforced by a horizontal penetration sealing plate, and the horizontal bars above the welding seal ring, sealing ring between the fully welded steel connections and sealing. Sealing plate width of not less than 400mm, are embedded in the concrete floor of 200mm, the first poured concrete should be higher than 200mm above the surface of the base plate, the plate thickness of not less than 3mm, in order to ensure a certain stiffness of steel construction, preferably steel longitudinal direction 50mm folding sides, about 30 degrees off the edge; 2, sealing plate to be substantially in place, should be minimized among excuse plate, the interface between the steel plates can be welded lap, lap length should be greater than 400mm, the weld must fully welded. Steel water stop and rubber water-stop compared to the advantages than rubber water-stop, one of the most obvious drawback is rusty, post-processing trouble, so far as possible the use of rubber water-stop construction; (there, Gigi brief rubber water-stop installation requirements: water stop is in the concrete casting process in which part or all of the water embedded in concrete, concrete has many sharp stones and sharp steel head due to the tear strength plastics and rubber Bira Strong stretch 3-5 times lower, water stop once punctured or torn, no outside force large gap will expand, so water stop position and concrete pouring process, should pay attention to positioning methods and pouring pound pressure, in order to avoid water stop was punctured, so water stop position and concrete pouring process, should pay attention to positioning methods and pouring pressure, in order to avoid water stop was punctured, affect the sealing effect) 3, Mounting direction question, whether horizontal or vertical steel plate water stop stop, must make two warped surface mount towards the positive side; (bent surface facing the pressure of water "positive side", it is necessary, because you can stop the water along the sealing plate sink in.) If the construction site do backwards, you must be reworked. Otherwise, there would be no effect of the sealing plate. 4, water stop are generally mounted in a position after pouring, water requirements of Basement board Reveals or construction joints, exposed to long out period, to make protective treatment, such as brushing rust and other measures .
