PROBLEM TO BE SOLVED: To inhibit the promotion of corrosion, and to exchange columns simply as required by deforming the front end section of the buried column, burying a column bearing part in conformity with the deformed section and fixing the column bearing part by concrete. SOLUTION: In a body section, a cylindrical bottom sections formed in a cross-shaped base, and an upper section is held down by packings for fixing. The packings 2, 3 for fixing bury a clearance between a support 1, in which notches are formed to the cross-shaped column bearing part in a cross shape, and a cylinder 4, fasten the support and the upper section, and fill the role of the prevention of rainwater and the effect of impact relaxation. The cross- shaped projecting sections of a column bearing obviate inclinations to the front- rear and left-right directions by a wind and rotation of the support, and stabilize the bottom section by combining the support and the irregularities of the column bearing part. |
