PURPOSE:To enable construction to be executed safely and economically without adverse effect from ground side by casting a bridge pier in-place by making use of an inverse triangular supporting bracket wherein weight in the vertical direction is supported by the basement of the bridge pier, and horizontal displacement is restrained by the bridge pier. CONSTITUTION:The supporting bracket 1 of a truss structure made of steel members composed of a vertical column 2, a support section 3, an oblique column 4 and truss members 5, is rested on the footing 8 of a bridge pier 7. Then, the vertical column 2 is fixed onto the bridge pier 7 with connecting members 10 such as PC steel bars and the like. Following which, a frame 6 is assembled using the top of the support section 3 as a work stand. After the frame has been assembled, concrete is placed in the frame so that an in- place girder 11 is constructed integrally with block bodies 9b, 9c, 9d and the like. |
