Will the metal support glass curtain wall aluminum alloy pillars on the support of the round hole is appropriate to use long hole, what does that mean?
Round hole directly fixed, long hole is used to adjust the spacing.
On the fulcrum for the fixed bearing, the lower fulcrum for the movable bearing. So that the aluminum alloy vertical bar in the state of tension, the force calculated by bending components calculated.
Upstairs to say on the fulcrum for the fixed bearing, the lower fulcrum for the movable bearing, because the curtain wall belongs to the subordinate structure, there must be some anti-settling deformation ability, such as aluminum alloy column elongated metal components such as tensile capacity Pressure and strong, stable, so the design of its design for the pull-bending components, so that you can explain the fulcrum for the fixed bearing (round hole), the lower bearing long hole (can be vertical displacement)
