Constructing Method of Non-Bridge Seat Bridge

摘要

The present invention is characterized in that a horizontal shear resistance and a shear key for hinge behavior are formed in a basic alternation and a horizontal shear resistance and a shear key groove corresponding to a shear key for hinge behavior are formed on the girder, The present invention relates to a method of constructing an unshifted left and right unshifted bridges, wherein a horizontal shear resistance and a shear key for hinge movement are interlocked with a shear key groove so as to perform a hinge movement. According to a preferred embodiment of the present invention, (a) a girder having a shear key groove is formed at one end in the longitudinal direction or at both ends in the width direction, step; (b) excavating the bottom of the ground to be installed at a certain depth; (c) a horizontal shear resistance and a shear key for hinge behavior are formed by projecting upward at an entire length in the width direction or at regular intervals in the width direction, and a shear key for horizontal shear resistance and hinge behavior is formed by a Dowel bar Constructing a basic shift; (d) installing an elastic support on an upper part of the foundation alternation in which the widthwise center portion of the girder end is fixed; (e) placing a girder on an upper portion of the basic shift so that the shear key groove engages the shear resistance for lateral shear resistance and the shear key for hinge behavior; (f) casting concrete to form a hinge behavior block so that a dowel bar is embedded between the girder and the girder on the upper part of the basic alternation; (g) installing a bottom plate reinforcing bar on top of the girder, foundation alternating and hinge building blocks; (h) casting concrete on the upper and back sides of the girder, foundation alternating and hinge behavior blocks to form a wall alternation and a bottom plate; (i) forming a backfill by backfilling the backside of the basic shift and the wall shift; (j) installing a connecting slab on top of the backfill on the backside of the wall and alternating between the bottom plate and the roadway.
