PROBLEM TO BE SOLVED: To provide a reinforcement structure of a rigid guard fence capable of satisfactorily improving the proof stress of an existing rigid guard fence at a collision of a vehicle so as to bear a collision of a vehicle which has increased in size as compared to the time when the rigid guard fence is constructed, and capable of being constructed in a short period with little industrial wastes.SOLUTION: The reinforcement structure of a rigid guard fence vertically disposed along a road includes a top beam member 11 which is provided to a top part 90A of a rigid guard fence 90 extending in a direction along a road. The top beam member 11 includes: a pair of gripping parts 12B and 14B which are opposite to each other while gripping both sides of the top part 90A of the rigid guard fence 90; and a connection part 12A which is disposed above the top part 90A of the rigid guard fence 90 and connects the opposing gripping parts 12B and 14B. The top beam member 11 is attached to the rigid guard fence 90 by means of an anchor 50 embedded in the top part 90A of the rigid guard fence 90.SELECTED DRAWING: Figure 1 【課題】剛性防護柵の建設当時と比べて大型化した車両の衝突に耐えられるように、既存の剛性防護柵の車両衝突時の耐力を十分に向上させることができ、かつ、短工期での施工が可能であるとともに施工の際に産業廃棄物もほとんど発生しない剛性防護柵の補強構造を提供する。【解決手段】道路に沿って立設された剛性防護柵の補強構造であって、剛性防護柵９０の頂部９０Ａに設けられて道路に沿う方向に延びる頂部梁部材１１を備えてなり、頂部梁部材１１は、剛性防護柵９０の頂部９０Ａの両側面を挟み込むように対向する挟み込み部１２Ｂ、１４Ｂと、剛性防護柵９０の頂部９０Ａよりも上方に配置されて対向する挟み込み部１２Ｂ、１４Ｂ同士を連結する連結部１２Ａと、を有し、かつ、頂部梁部材１１は、剛性防護柵９０の頂部９０Ａに埋め込まれたアンカー５０によって剛性防護柵９０に取り付けられている。【選択図】図１
