Fastener type steel pipe scaffold composed of two components? What are the roles?
Bowl buckle steel pipe scaffolding when using steel pipe, as a "single steel pipe scaffolding"; when using the steel cross bar, for the "steel pipe based scaffold".2.2 according to the vertical and horizontal transmission force between the vertical and horizontal1) the frictional force acting on the contact surface. That is, the friction force at the contact surface of the joint is pressed to support the load of the cross bar and is transmitted to the vertical rod;2) welding force. 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. This method is more common in the horizontal bar placed in the top of the scaffolding;4) shear force of pin. That is to say, the connecting rod and the hole of the vertical rod are connected by the pin rod through the vertical connecting plate of the transverse rod to realize the double side shear action of the connecting rod and the pin rod. This method is rarely seen in the connection between the rod and the vertical rod.
Classification of steel pipe scaffoldThe domestic steel pipe scaffold material production with steel tubular scaffolding, bowl button steel scaffolding, socket type steel pipe scaffolding, scaffolding doors, and every kind of the scaffolding, hanging scaffold steel pipe scaffolding and other materials. Proceed from its material and structure, and can be roughly divided as follows:
2.1 divide the material according to the bar1) single specification steel pipe scaffold. It only uses a steel pipe specifications, such as steel tubular scaffolding, welded steel pipe using only 48 * 3.5.2) a variety of specifications of steel pipe scaffolding. The utility model is composed of two or more steel pipes of different specifications, such as a door type scaffold.3) steel tubular 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 and so on.
