The present invention relates to a column-integrated foundation to effectively transmit an upper load to the ground by extending a concrete column into a pre-excavated boring hole. A column-integrated foundation according to the present invention comprises: a column formed into a concrete tube of which the cross section is circular; multiple full thread bolts coupled to the bottom of the column and extended downwards; and multiple anchor plates coupled to the bodies of the respective full thread bolts and separated from each other at regular intervals, wherein each of the anchor plates is thread-coupled to the body of the full thread bolt by having a coupling hole of which the center has female threads. According to the present invention, a column load can be safely transmitted to the ground when the column formed into the concrete tube of which the cross section is circular is extended into the pre-excavated boring hole, and can be integrated with the foundation without damage to or deformation in a column main body. In addition, a prefabricated concrete structure having the column and the foundation, which are integrated with each other, can be constructed only by a process of placing concrete after inserted into the pre-excavated boring hole, thereby simplifying an installation process, minimizing construction errors, and reducing construction periods and construction costs. |
