Aluminium Scaffolds The force transfer method between the verticals, ledgers and other components

May 29, 2018

For the aluminum scaffolding, a variety of different force transmission methods can also be presented during the connection of the vertical pole and the vertical pole, including the supporting force of the socket and the butt, and the shear resistance of the pin and the bolt connected to the bolt. The meshing transmission force of the connection can maintain the overall structure of the aluminum scaffold in a stable and good state.


The supporting force of the aluminum scaffolding pole butt-joint is the butting of the upper and lower poles, and the connecting rod or the socket-inserting tube is used to ensure the good state of the docking; and the so-called screw-coupling of the meshing transmission force is to make The outer thread of the inner tube is in mesh with the inner thread of the outer tube, and the latter two force transmission methods are mostly used to adjust the height of the pole connection.


In addition to the different transmission methods of the connection between the vertical pole and the vertical pole, the way of transmitting vertical plum between the horizontal rod and the vertical pole of the aluminum scaffold is also different. On the one hand, it is possible to rely on the frictional force of the contact surface, that is, to rely on the frictional reaction force after the contact surface at the node is pressed to support the ledgers load and transfer it to the vertical rod, such as the action of the fastener, by tightening the bolts. Positive pressure generates friction.


On the other hand, the force will be transmitted through the weld, and most of the ledgers and poles are connected in this way. The portal scaffold is also in this way; there are also direct pressure transmission force, which is more common in ledgers. An aluminum scaffold rests on top of the pole.


In addition, the shear transmission force of the pin is also one of the ways for the aluminum scaffold ledgers and the vertical bar to transmit the force. It is necessary to use the pin to penetrate the holes of the vertical connecting plate and the vertical bar of the horizontal bar so as to realize The coupling and the pin are subject to shear forces on both sides, thus ensuring the stability of the entire scaffold.


In the actual application process, the user needs to select an appropriate force transmission method according to the different types of aluminum scaffolds and the actual operation requirements and conditions. This can not only ensure the stability of the structure, but also can operate more efficiently and save time.
