Classified according to the material of the rods: shelf tubes of single-standard steel pipes (for example: fastener-type scaffolding), shelf tubes of steel pipes of various specifications (for example: door-type scaffolding), scaffolds mainly made of steel pipes (for example: with connections and fixed Steel plate scaffolding, roommate base scaffolding, channel steel top bracket scaffolding)
Classification according to the vertical force of vertical poles and crossbars:
2.1 According to the frictional force transmission of the scaffold in contact with the ground, for example: the role of the fastener, that is, the friction force generated by the normal pressure of the fastening bolt.
2.2 Force transmission according to the weld: the socket connection between the vertical bar and the horizontal bar. Example: door frame
2.3 According to the direct pressure transmission force: Most of the force transmission occurs in the form of scaffolding at the top of the pole.
2.4 Relying on the pin rod shear force transmission: the vertical connecting plate of the horizontal bar and the hollow of the vertical bar are used to complete and realize the connection with the pin bar, and the pin bar receives the shear force at this time. This is not common.
