Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of convertible support devices for steel pipe scaffold. BACKGROUND

[0002] Steel pipe scaffold, disc type scaffold, bowl type scaffold and other steel pipe scaffolds are mainly used for various forms of concrete cast-in-place structure support and operation platform frame, and a small number of them are used for temporary support of steel structure hoisting horizontal components. As steel structures can meet the needs of various shapes in the construction market, they have gradually become the mainstream structure form in today's construction market. Therefore, steel structure installation measures are also diverse. For special-shaped net rack steel structures and under site restrictions, the mainstream overall lifting, overall hoisting and sliding method installation are not applicable. Various operation platforms and temporary support jigs are required, such as Bailey beam support, scaffold temporary support and work platform. Among them, special-shaped (hyperbolic) net rack steel structures use strip-by-strip and block-by-block installation, and scaffolds can be used as operation platforms and temporary support measures during high-altitude bulk loading. The advantages are reliable, safe and convenient to operate. However, the scaffold uprights and support jacks correspond one-to-one, and the uprights can only be arranged in rectangular intervals. Therefore, when used for special-shaped net rack member support, the jacks and net rack members cannot be correspondingly supported. Therefore, it is the research direction of the utility model to design a device that can use conventional scaffolds as operation platforms during steel structure strip-by-strip and block-by-block installation and high-altitude bulk loading, and can also solve the flexible support of jacks and net rack members when conventional scaffolds are used for special-shaped steel structure net rack strip-by-strip and block-by-block installation and high-altitude bulk support.
