Abstract

PURPOSE:To improve the bearing force of a column and construction efficiency by disposing main reinforcements at four corners and hoop reinforcements around to form a precast concrete column member having a hollow part of circular cross section, then disposing a reinforcement cage and a steel frame in the hollow part, and casting concrete therein. CONSTITUTION:Main reinforcements 2 are disposed at four corners, and hoop reinforcements 1 are arranged around. Concrete is then cast in leaving a hollow part 4 of circular cross section, beam jointing spaces 6 and main reinforcement joint spaces 7 with the upper ends of the main reinforcements 2 in the protruded state to form a precast concrete column member 5-1. A reinforcement cage and a steel frame are further disposed in the hollow part 4, then beam members are fitted into the beam jointing spaces 6, and concrete is cast therein. The column members 5-l are added in succession, and the column member 5-1 is used also as a form. The yield strength of the column is thereby improved, and construction efficiency can be improved.

2. Description of the Related Art Conventionally, as a precast concrete column material composed of a half-made surface layer portion and a hollow portion used for construction of a concrete column, a cover concrete type shown in FIG. 9 and a hoop reinforcement driving type shown in FIG.
There was a hoop muscle and a main muscle driving type shown in. In the cover concrete type, neither the hoop reinforcement 1 nor the main reinforcement 2 is located inside the hollow portion 4 but inside the concrete of the surface layer portion 3. For this reason, the cover concrete type has a larger column diameter than usual because the cross-sectional area of the ineffective portion that is not reinforced is large. In the hoop driven type, the main bar is pushed into the inner hollow portion 4 and the cross-sectional performance is deteriorated, so that the column diameter is also larger than usual. In the hoop reinforcement and the main reinforcement driving type, since the main reinforcement is connected inside the hollow portion 4, it is pushed inward and the cross-sectional performance deteriorates, so that the column diameter becomes larger than usual. Moreover, since the lateral pressure of concrete is applied when pouring concrete, it is necessary to increase the thickness of the plate and increase the strength of concrete.
