Material classification of scaffold pipe :

(1) From a single specification of steel pipe scaffold pipe: it is used with the same specification of steel pipe

(2) by a variety of specifications of steel pipe combination of scaffold pipe: it is composed of two or more different specifications of steel pipe combination (such as: door scaffold)

(3) all steel pipe - based scaffolding: its meaning can be understood as all steel pipe - based, and by other types of steel rod auxiliary composed of scaffolding (such as: with the base type of scaffolding or the channel steel roof support type of scaffolding and scaffolding with a connection fixed steel plate)

Distinguish the vertical force of scaffold pipe by vertical rod and horizontal rod:

(1) Rely on the scaffold contact ground friction effect transmission force: that is, can be understood as by the scaffold node in the ground contact friction compression after the counterforce to support the load of the bar and then pass it to the vertical rod form (for example: the role of the fastener is through the positive pressure of the bolts friction force)

(2) depending on the weld transmission force: can be understood as the crossbar and vertical rod socket connection (with socket joints), for example: the door frame is composed of this way.

(3) rely on direct pressure transmission force: most in the very dry use at the top of the scaffold pole transmission force

(4) rely on pin shear type transmission: that is, through the horizontal rod vertical connecting plate and vertical rod hole to complete and realize the connection, then the pin by shear action on both sides.This method of use is not very common in crossbar and vertical bar connections.
