In physics, pressure is defined as the pressure on a unit of area. We regard the area through the wall screw as a unit area, then, the pressure on the screw through the wall is equal to the pressure. The pressure of concrete on the through-wall screw can be calculated by the pressure of the liquid, ie pressure = liquid density x gravity x depth. We know that the density of concrete is determined and gravity is determined. The only uncertainty is the depth, which is the height of the wall. Therefore, the higher the wall height, the greater the pressure, ie, the greater the pressure, and vice versa. We have seen that there is no question of wall thickness at all during the entire process. Therefore, the important influence factor of the pull force applied by the wall screw is the height of the wall, not the thickness of the wall.
Now everyone should understand it. When we need to use a wall screw, do not know how to use the specifications, we can say about the height of the wall to the boss who sells through the wall screw, without worrying about the thickness of the wall. La!
Talking about the factors affecting the penetration of the screw of the wall - height? thickness?
Through the wall screw that is the pull screw, we have engaged in the production process of the screw for many years and found that many customers have the misunderstanding of the screw to bear the understanding of the pull: Some customers think that the wall is thicker, through the wall screw will withstand more pull Big. Below, we will analyze through the knowledge of physics, if it is really the case.
