ROAD BRIDGE GUARD FENCE AND INSTALLATION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a road bridge guard fence superior in durability and capable of reducing work period, and an installation method thereof.SOLUTION: A continuous fiber reinforcement 3 is used as a reinforcement material of a precast wall handrail 1. A fixed reinforcing portion 3c is formed by untwisting a part of a portion which is inserted into a through hole 4a in a precast wall material 4. In the fixed reinforcing portion 3c, the tip part of a plurality of untwisted strands is formed in a lantern shape by bundling on a core material using a binder.SELECTED DRAWING: Figure 1
【課題】耐久性に優れ、工期短縮が可能な道路橋防護柵及びその設置工法を提供する。【解決手段】連続繊維補強材３をプレキャスト壁高欄１の補強材として用いるとともに、連続繊維補強材３として、より線状のものを使用し、プレキャスト壁材４の貫通孔４ａ内に挿入される部位の一部のよりを解いて定着補強部３ｃを形成した。また、定着補強部３ｃは、よりを解いた複数の素線の先端部分を結束具を用いて芯材の周りに束ねることによって提灯状に形成した。【選択図】図１
