<3>Differentiate according to the vertical force of vertical poles and horizontal poles ① Relying on the friction of the scaffolding contacting the ground to transmit force: that is, it can be understood as relying on the reaction force of the scaffolding nodes when they are in contact with the ground to support the crossbar load. Measure the force and then transmit it to the vertical pole (for example: the function of the fastener is the friction force generated by the positive pressure of the tightening bolt)
② Relying on the weld to transmit the force: it can be understood as the horizontal pole and the vertical pole The socket connection of the rod (with socket joint), such as the door frame, is constructed in this way.
③ Relying on direct pressure to transmit force: Most of the force is transmitted by scaffolding placed on the top of the vertical pole
④ Relying on shear resistance of pin rods to transmit force: that is, using a pin rod to pass through the horizontal bar The vertical connecting plate and the hole in the vertical pole are used to complete and realize the connection. At this time, both sides of the pin pole are subjected to shear force. This method of use is no longer very common in connecting horizontal bars and vertical bars.
Uses of rack pipes
Shelf pipes are mainly used for construction pipes, construction site supports, and safety protection supports. Its function is also commonly used in natural gas transmission pipelines, because the wall thickness of the pipeline meets the standards and the tensile strength and cold bending properties are relatively in line with regulations.
