The invention provides a mold for manufacturing a
reinforced concrete circular column. The mold comprises circular hoop film, wherein the innermost layer of the circular hoop film is in contact with circular column concrete, the circular hoop film is externally provided with a circular hoop
keel composed of a plurality of wooden keels, two
layers of composite nested plates are composed of A platesand B plates, and the inner sides of the A plates and B plates are provided with semicircular concave dies respectively; one part of the wooden keels forming the circular hoop
keel is fixedly connected to the surface of the concave die at the A plate side, and the other part of the wooden keels is fixedly connected to the surface of the concave die at the B plate side. The invention further provides a construction method of the mold for manufacturing the
reinforced concrete circular column. Two multi-layer laminated plates covered with film and a wood square layer sandwiched in the middle aremade into the composite nested plates; the composite nested plates are
cut and divided into the A plates and the B plates from the middle, the A plate on the upper layer and the A plate on the lowerlayer are fixedly connected with the wooden keels, and the B plate on the upper layer and the B plate on the lower layer are fixedly connected with the wooden keels; the inner surface of the circularhoop
keel is covered with the circular hoop film; and the circular hoop film is coated with a separant. The mold for manufacturing the
reinforced concrete circular column and the construction method thereof have the advantages that the weight is smaller, the reshipment is convenient, turnover can be carried out many times, the cost is reduced, the integrality is good, the strength and rigidity aregood, the
assembly and disassembly are simple, and the construction efficiency is improved.
