Concrete column connection reinforcing method and device

The invention discloses a concrete column connection reinforcing method and device.The method comprises the steps that through holes are formed in a concrete slab, the positions of the through holes correspond to the positions of the four corners of a concrete column, and the shapes of the through holes are the same as the shapes of the L-shaped cross sections of the four corners of the concrete column; one end of the column reinforcing member is arranged on the concrete plate, and the other end penetrates through the through hole to be connected with the column corner of the concrete column; and a beam reinforcing member is arranged on the concrete beam and is fixedly connected with the column reinforcing member. The invention further discloses a concrete column connecting and reinforcing device. According to the method, the bearing capacity of the beam column can be remarkably improved, mounting and positioning are fast, the construction technology is simple, the structural safety is high, and the construct
