Thus, the two-layer concrete silo top ring beam construction platform is formed.
The second layer steel-pipe layer is close to the upper opening of the barrel body and sets up in the steel-pipe layer 2 to form the operation platform who is used for erectting the ring beam template, the interval is 1.2 ~ 1.5m usually between first layer steel-pipe layer and the second layer steel-pipe layer. The interval between the steel pipes 21 of each layer of steel pipe layer 2 is related to the pipe diameter of the selected cantilever scaffold pipe 3, and the interval between the steel pipes 21 of each layer of steel pipe layer 2 is usually 1.2-1.35 m.
The upright pole scaffold tubes 7, the cross rod scaffold tubes 8, the diagonal bracing scaffold tubes 4 and the overhanging scaffold tubes 3 are connected by the existing scaffold tube-to-tube fasteners; cantilever scaffold pipe 3 plays the effect of the roof beam of encorbelmenting, and horizontal pole scaffold pipe 8 is used for connecting every layer of cantilever scaffold pipe 3 in order to form wholly, and two-layer cantilever scaffold pipe 3 about pole setting scaffold pipe 7 is used for connecting plays the effect of supporting upper operation platform, and 4 one ends of bracing scaffold pipe are supported and are leaned on section of thick bamboo wall 1, and one end is connected with the free end of encorbelmenting scaffold pipe 3 to keep the stability of scaffold. The upright pole scaffold tube 7, the cross rod scaffold tube 8, the inclined strut scaffold tube 4 and the cantilever scaffold tube 3 all adopt carbon structural steel tubes with phi 48 multiplied by 3.5.
