The bottom and the top adopt an adjustable base and an adjustable jacking to increase the stability of the bottom support and the top support and simultaneously improve the applicability of the formwork system under the requirements of different bottom elevations and top elevations. Therefore, the socket type disc buckle type scaffold is convenient to mount and dismount, rapid in turnover, high in safety and attractive in vertical face, and is widely applied to building of a formwork system of building engineering.

However, at present, although some temporary stands have been tried to adopt socket-and-spigot type disk buckle type scaffolds and have achieved a good effect, the existing disk buckle type temporary stands have a low standardization degree, a slow assembling speed and a high early-stage design cost. Therefore, how to realize the modularized rapid assembly of the temporary stand with the steel structure on the premise of meeting the requirements of structural safety and building fire prevention becomes a technical problem to be solved urgently by technical personnel in the field.
