PROTECTIVE FENCE, METHOD FOR INSTALLING PROTECTIVE FENCE, AND METHOD FOR REPLACING FLOOR SLAB

To shorten a traffic regulation period required for fixing a guard fence.SOLUTION: A guard fence 1A partitioning a road 50 formed by floor slabs 21, 22, 23, 24 includes: the floor slabs 22, 23; a guard fence part 10A partitioning the road 50; a floor slab through-hole part 20h vertically penetrating the floor slabs 22, 23; and a fixing member 30 inserted into the floor slab through-hole part 20h and fixing the guard fence part 10A to the floor slabs 22, 23. Since the guard fence part 10A is fixed to the floor slabs 22, 23 by the fixing member 30 which is inserted into the floor slab through-hole part 20h vertically penetrating the floor slabs 22, 23 and fixes the guard fence part 10A to the floor slabs 22, 23, more works required for fixing the guard fence part to the floor slab can be performed from a lower surface of the floor slab compared with a conventional technique in which a temporary guard fence is fixed to the floor slab by an anchor driven into an upper surface of the floor slab.SELECTED DRAWING: Figure 3 【課題】防護柵を固定するために要する交通規制期間を短縮する。【解決手段】床版２１，２２，２３，２４により形成された道路５０を区画する防護柵１Ａにおいて、床版２２，２３と、道路５０を区画する防護柵部１０Ａと、床版２２，２３を上下に貫通する床版貫通孔部２０ｈと、床版貫通孔部２０ｈに挿通され、床版２２，２３に防護柵部１０Ａを固定する固定部材３０とを備える。床版２２，２３を上下に貫通する床版貫通孔部２０ｈに挿通されて床版２２，２３に防護柵部１０Ａを固定する固定部材３０により、床版２２，２３に防護柵部１０Ａが固定されるため、従来の床版の上面に打ち込まれたアンカーにより仮設の防護柵が床版に固定される技術に比べて、床版に防護柵部を固定するために必要な作業のより多くを床版の下面からの作業にできる。【選択図】図３
