What is scaffolding pole, bar, scissors support?
2.2 according to the vertical and horizontal transmission force between the vertical and horizontal1 by the contact surface friction force transmission, that is, at the junction of the contact surface of the pressure after the friction force to support the transverse load and transfer it to the vertical pole, such as the role of the fastener, through the positive pressure of the bolt to produce friction;2 by the welding force transmission. Most of the cross bar and vertical rod socket connection is used in this way, the door frame is also this way;3) direct pressure transmission force. This method is more common in the horizontal bar on the top of the scaffolding;4. The shear force of the dowel bar is connected with the vertical connection plate of the cross bar and the hole of the vertical rod to realize the connection and the shear force between the two sides of the pin rod
Bowl buckle steel pipe scaffolding when using steel pipe, as a single steel scaffolding, when the use of steel when the edge of the cross bar, for the steel based scaffolding
1 divide the material according to the bar1) a single standard steel scaffolding steel pipe. It uses only one standard, such as steel tubular scaffolding, welded steel pipe using only 48 * 3.5.2, a variety of specifications of steel scaffolding, which consists of more than two kinds of different specifications of the steel pipe, such as door scaffolding3) steel based scaffolding. As to the steel pipe, and combined with other type of steel pieces composed of scaffolding, such as the channel has a base in the backwater or scaffolding, connecting steel scaffolding.
