PROBLEM TO BE SOLVED: To provide a mounting structure of a concrete wall railing in which collision energy at the time when a vehicle collides is transmitted to a concrete floor plate while being reduced, and thereby the breakage of the concrete floor plate can be avoided.SOLUTION: A concrete wall railing 12 is a precast concrete member obtained by integrally forming a wheel guard part 14 to a wall body part 13, and a bolt insertion hole 15 and a fastening recess 16 are formed in a lower end portion of the concrete wall railing 12. A spring structure fixing bracket 17 is mounted in the inside lower end of the wheel guard part 14. Embedding rebars 19a, 19b of the spring structure fixing bracket 17 are embedded to the concrete wall railing 12 without being connected with the rebar of the wall railing 12. The tip of an outside anchor bolt 20a is fastened to the fastening recess 16, and the tip of an inside anchor bolt 20b is fastened to an overhang fixing part 18b of the spring structure fixing bracket 17, and thereby the concrete wall railing 12 is installed at a side edge of a concrete floor plate 11. |
