To provide a concrete product preventing a reinforced concrete bridge pier or building from falling in an earthquake or telegraph poles from bending and further preventing a steel encased reinforced concrete pile or a reinforced concrete column embedded in the underground by the earth drill method from winding due to the loosened ground.

A wide flange-shaped steel column 3 with an appropriate width is erected as a column for a reinforced concrete building or at the center of a bridge pier and a cross-shaped receiver body 2A made of wide flange-shaped steel is provided at the lower part thereof and the contact parts are welded together. This structure is put on a concrete foundation laid on a piled zone. And four bracings 4 made of wide flangeshaped steel are welded between an appropriate position of the upper part of the cross-type H-shaped steel receiving body and an appropriate position of the side face of the H-shaped steel column 3. In a bridge pier, the lower side of the central part of a H-shaped steel beam with the same length with the width of a road is welded with the upper end of the column 3 so as to make a T-shaped form and reinforcements are arranged around the peripheral parts and concrete is placed therein to construct a bridge pier.
