Method of manufacturing column base hardware and column base hardware

摘要

PROBLEM TO BE SOLVED: To provide a column base hardware capable of efficiently transmitting a shearing force acting on a column base portion of a column member to a foundation concrete, simplifying the manufacturing process thereof, and reducing the manufacturing cost, and a method for manufacturing the column base hardware. I will provide a. SOLUTION: This is a column base metal fitting 24 provided at a lower end of a column member 5 erected on a foundation concrete 3, and is formed so that its planar shape is larger than the horizontal cross-sectional shape of the column member 5. A plate-shaped base plate 26 in which the lower end portion of the pillar member 5 is fixed to the upper surface thereof, and a plurality of pillar-shaped projecting portions 28 provided so as to project downward from the lower surface of the base plate 26, the base plate 26 and The plurality of projecting portions 28 are integrally molded by casting, and the projecting portions 28 are embedded inside the foundation concrete 3 so that the lower end portion of the projecting portion 28 is located below the surface of the foundation concrete 3. It was configured in. [Selection diagram] Fig. 1
