As we all know, the extensive application of water stop screw in the project brings a lot of benefits to the project, especially in the water stop, waterproof, it is also important to highlight the obvious, nearly the construction unit are using the water stop screw to the project quality The greatest guarantee is that in the process of continuous innovation and upgrading of products, various models of water-blocking screws follow. The construction unit is faced with the need to choose the right screw, and the next one is to calculate the amount of the screw. The new three-stage water-blocking screw has a full advantage and is the preferred construction unit.
Example: basement negative two-story external wall: The project underground outdoor wall thickness is 40 cm. The height of the wall is 420 cm, and the perimeter of the outer wall is 1166 cm. According to the three-stage sealing screw, the lower half of the wall is arranged, and the distance between the water stop screw bolts is 40 centimeters. The two ends of the outer rod are matched with two mountain cards. 2 A nut; the top half of the four water stop screw spacing 50 cm, the outer pole 2 mountain card, 2 nuts.
Three-stage sealing screw length=(wall thickness)+2*(stencil thickness+square thickness+steel diameter+mountain card thickness+nut thickness+external rod elongation 4 cm), three-stage sealing screw The amount used = 1166 divided by 0.45 * (6 + 4) = 25912, while the amount of mountain type nut nut is: 25,912 * 2 = 51,824, through the calculation of the sample, we can easily understand the total cost of three-stage sealing screw Probably about how much, and the three-stage sealing screw can be repeated because the outer rod and the joint nut can save a lot of cost. Therefore, the three-stage water-blocking screw has recently been favored by construction friends.
