Rely on the contact surface friction force transmission, that is, by the contact surface of the node after the compression of the friction force to support the transverse load and transfer it to the vertical pole, such as the role of the fastener, by tightening 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
1) a single standard steel scaffolding steel pipe. It uses only one standard, such as steel tubular scaffolding, welded steel pipe using only 48.3 * 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. A bowl type steel tube scaffold when using steel bar when the "scaffolding" when using the single pipe; take the side of the steel bar, "steel based scaffolding".
Single row of scaffolding is generally used for internal wall plastering, brush paint, and so do not need to bear the work of a single row of scaffolding need to hold the pole against the wallChinese now used in the steel pipe scaffold material made of 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. The materials and structures to proceed, and can be roughly divided as follows:Material division according to bar
Single row scaffolding -- only a row of pole, one end of a short bar on the wall. Use the scaffolding scaffolding double row scaffolding consisting of two rows from the outside pole and longitudinal and transverse horizontal bar (low grade can not add pictures). Double row scaffolding generally used for masonry masonry bearing to throwing cement brick. The single row scaffolding for internal wall plastering, paint brush, do not need the single row bearing engineering scaffold to pole support against the wall
