Arc-shaped reinforcing steel bar plate structure applied to pre-constructed concealed hole construction

An arc-shaped reinforcing steel bar plate structure applied to pre-constructed concealed hole construction comprises an arc-shaped reinforcing steel bar plate and an arc-shaped reinforcing steel bar frame, a reinforcing steel bar frame groove is formed in the arc-shaped reinforcing steel bar plate, and the arc-shaped reinforcing steel bar frame is fixedly connected into the reinforcing steel bar frame groove. A large amount of working hours and labor force can be saved, consumption and waste of materials are reduced, occupation of a construction site is reduced, and good economic benefits are achieved. The arc-shaped steel bar frame has the following functions that firstly, the bearing capacity of the arc-shaped profiled steel sheet in the hidden hole large-size cast-in-place concrete pouring process can be improved; the problems of overall instability, overlarge deformation and the like are avoided; secondly, the bonding capacity between the concrete and the arc-shaped profiled steel sheet can be improved; t
