CONNECTING STRUCTURE FOR PRECAST CONCRETE COLUMN TO CAST-IN-PLACE FOOTING

PURPOSE: A connecting structure of a pre-cast concrete column and field placing concrete base plate are provided to efficiently prevent a punching shear and reduces costs because a structural steel base plate of high strength is not necessary. CONSTITUTION: A connecting structure of a pre-cast concrete column and field placing concrete base plate comprises a pre-cast concrete column(10), a cast-in-place concrete footing plate, a plurality of shim plates, a plurality of anchor bolts, and a non-shrinkage mortar. An expansion type column base is formed into a body in the lower part of the pre-cast concrete column. The plurality of shim plates is installed between the base plate and PC post to adjust a height. The plurality of anchor bolts penetrates the expansion type column base. End parts of the anchor bolts are mounted in the base, thereby joining the columns to the base plate as one body. An interval of the upper part of the base plate and the bottom surface of the expansion type column base are filled with the non-shrinkage mortar.
