Division of materials
(1) a single standard steel scaffolding. It only uses a specification of steel, such as steel tubular scaffold, only Ф48 × 3.5 welded pipes.
(2) a combination of a variety of specifications of steel scaffolding. It consists of two or more different specifications of steel pipes, such as gantry scaffolding.
(3) consisting mainly of steel scaffolding. Namely steel-based, supplemented by other types of scaffolding steel rod member constituted as provided base channel backwater or scaffolding, there are connecting plate pick scaffolding.
Press the vertical force
(1) by friction of the contact surface force transmission. Namely by frictional contact surfaces at the node after pressing reaction force to support the rail loading and pass pole, such as the role of fasteners, bolts through positive pressure on the friction force;
(2) by weld force transmission. Most of the bar and the pole of the socket coupling is to use this way, the door frame also belong in this way;
(3) direct pressure force transmission. This way is more common in the bar resting on top of the scaffolding pole;
(4) by the pin shear force transmission. That is with the pin through the crossbar and uprights vertical coupling plate holes achieve coupling, the pin-sided by the shear force.
In the pole and the pole coupling, there are three kinds of power transmission mode:
(1) docking socket supporting force transmission. That butt up and down the pole, using connecting rods or intubation to ensure docked in good condition;
(2) the pin connected to the pin shear force transfer;
(3) connected to the fastener engaging force transmission. That is externally threaded inner tube and the outer (sleeve) female engagement force transmission tube. The latter two of which pole used for power transmission mode to adjust the height requirements connection.
Press the fixation mode
(1) fixed pitch connection: the coupling rod weldment on the fixed distance set, rod length stereotypes, stereotypes junction point spacing;
(2) variable from the junction: the coupling member is provided as a single piece, can be clamped by tightening the bolt on any part of the rod member.
Press the operation mode
(1) Insert the matter;
(2) Tighten the bolts.
