Quick construction device and construction method for precast concrete

The invention relates to the technical field of concrete prefabricated part building devices, and discloses a rapid concrete prefabricated part building device and method.The rapid concrete prefabricated part building device comprises a stand column body, the stand column body is used for building a cross beam body, reinforcing steel bars are fixedly arranged on the two sides of the stand column body, and auxiliary supporting plates are fixedly arranged on the outer sides of the reinforcing steel bars; the auxiliary supporting plate is arranged and used for positioning and pre-tightening when the cross beam body is installed, the plate grabbing mechanism is connected with a crane traction rope and used for adjusting the distance between the clamping plate mechanisms, and through the arrangement of the plate grabbing mechanism and the clamping plate mechanisms, the plate grabbing mechanism can drive the two clamping plate mechanisms to be close to each other or away from each other. Therefore, the effect of cl
