scaffolding scaffolding pole at the bar and the vertical force between the mode of transmission

Steel scaffolding pole at the bar and the vertical force between the mode of transmission:

1) by the friction force transfer contact surface. By the node that is pressed after the contact surface of the friction reaction force to support and pass the bar load pole, such as the role of fasteners, bolts through the positive pressure on the friction force;

2) Transmission by the weld. Most of the bar and the pole of the socket connection is used in this way, the door frame also belong in this way;

3) direct pressure force transmission. In this way more common in the top bar in shelving in the pole scaffolding ;

4) The shear force transfer lever by pin. The bar through the bar with a vertical pin link plates and the holes to achieve coupling pole, double pole off by shear force. This method of connection in the bar and the pole has been rare.

In addition, the pole and the pole of the connection, there are also three kinds of power transmission by:

1) The docking of the supporting socket load transfer. The upper and lower pole docking, the use of connecting rods or intubation to ensure that the dock in good condition;

2) connecting rod pin pin shear force transfer rod;

3) Connect the meshing screw buckle load transfer. That is outside the inner pipe and outer threads (sets) of pipes force transmission within the thread engagement. The latter two of which means more power transmission requirements for regulating the height of pole connection.
