The Function Requirements And Force Transmission Mode Of Aluminum Alloy Double Width Moving Scaffold

Apr 03, 2019

In the course of operation, the aluminum double width moving scaffold mainly transmits force by the friction of the contact surface. That is, the frictional reaction force after the contact surface of the joint is pressed to support the crossbar load and transmit it to the pole. If the fastener acts, the frictional force is generated by tightening the positive pressure of the bolt.

The aluminum double width moving scaffold is transmitted by the weld. Most of the cross-bar and the pole's socket connection are in this way, and the gantry also belongs to this way, directly bearing the force. This method is more common in the scaffolding where the crossbar rests on the top of the pole.

Aluminum double width moving scaffolds rely on pin shear resistance. That is, the pin is passed through the vertical coupling plate of the cross bar and the hole of the vertical rod to realize the coupling, and the pin is subjected to the shearing force on both sides.

The force transmission method of aluminum alloy double width moving scaffold

(1) The bearing force of the socket butt joint. That is, the upper and lower vertical bars are butted, and a connecting rod or a socket is used to ensure a good state of docking;

(2) The pin shear transmission force of the pin connecting pin;

(3) Engagement force of the screw connection. That is, the external thread of the inner tube meshes with the internal thread of the outer tube. The latter two types of force transmission are mostly used to adjust the height requirements of the pole connection.
