Description

Support frame and use method suitable for bracing rod installation in net rack or net shell TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure construction, in particular to a support frame and use method suitable for bracing rod installation in net rack or net shell. BACKGROUND

[0002] In the process of bracing rod installation in steel structure net rack or net shell (both of which are welded type circular pipes), a crane or a tower crane is often used for hoisting and positioning. Since the bracing rod is embedded in the main pipe component, the angle and position of the component need to be constantly adjusted for installation accuracy. However, the driver is far away from the installation position when hoisting with the crane or the tower crane, and the signal needs to be transmitted by the command personnel. Moreover, the hook steel wire rope is long and swings greatly, which increases the difficulty of accurate positioning of the bracing rod and prolongs the adjustment time. This not only wastes labor and machinery, but also delays the construction period.
