Mobile scaffold Varied specifications Installation is simple

(1) a single specification of steel pipe scaffold. It USES only one kind of specifications of steel pipe, such as the fastener type steel pipe scaffold, using only 48 x 3.5 Ф welded steel pipe.

(2) combination of a variety of specifications of steel pipe scaffold. It is composed of two or more different specifications of steel pipe, such as gantry scaffolding.

(3) is given priority to with steel tube scaffold. I.e., according to the steel tube is given priority to, supplemented by other steel bar of the scaffold, such as a channel steel top or base of scaffolding, have connection steel scaffolding, etc.

(1) the contact friction force. That rely on node interface after compaction friction reaction to support rail load and its to the stud, such as the role of the fasteners, created by the positive pressure of tightening bolts friction;

(2) the weld force. Most of the rail and socket connection is in this way, the door frame also belong to this way;

(3) direct pressure force. This way, see more at bar shelved in the vertical bar at the top of the scaffold;

(4) the pin rod shear force. In which vertical pin rod through the cross bar connecting plate and the vertical rod, pin holes to realize connection double shear effect.

In the vertical rod connected with the stud, there are 3 kinds of force transmission mode:

(1) socket docking handing down force. The poling docking, connecting rod or socket pipe is used to ensure the docking in good condition;

(2) the pin rod connecting pin rod shearing force;

(3) the screw connection of meshing force. The external thread of inner tube and outer tube (set) the internal thread of meshing force. Among them after more than two kinds of force transmission way used to regulate the stud connection to the height requirement.
