PROTECTOR OF UNDERGROUND BURIED OBJECT
To provide a protector of an underground buried object, having light weight, nonetheless having high cutting resistance.SOLUTION: A protector of an underground buried object comprises: a plate-shaped member 11 having a surface 11a on one side in a thickness direction, and a rear surface 11b on the other side in the thickness direction; and a pair of L-shaped members 12 which are fixed to the rear surface 11b, extend in a first direction orthogonal to the thickness direction, and are arranged while separated from each other in a second direction orthogonal to the thickness direction and the first direction. In a cross-section vertical to the first direction, each of the L-shaped member 12 has a first flat plate portion 12a extending in the other side in the thickness direction from the rear surface 11b, and a second flat plate portion 12b extending to the outside of the plate-shaped member 11 in the second direction, from an end on the rear surface side of the first flat plate portion 12a. The plate-shaped member 11 is composed of a metal material having a Brinell hardness of 100 or less, the L-shaped member 12 is formed of a metal material having a Brinell hardness more than 100.SELECTED DRAWING: Figure 2
【課題】軽量であっても高い切断抵抗性を有する地中埋設物の保護体を提供する。【解決手段】厚み方向における一方側に表面１１ａを有し、かつ厚み方向における他方側に裏面１１ｂを有する板状部材１１と、前記裏面１１ｂに固定され、前記厚み方向に直交する第１方向に延び、かつ前記厚み方向および前記第１方向に直交する第２方向に互いに離れて配置される一対のＬ字状部材１２と、を備え、前記第１方向に垂直な断面において、前記Ｌ字状部材１２のそれぞれは、前記裏面１１ｂから前記厚み方向における前記他方側に延びる第１平板部１２ａと、前記第１平板部１２ａの前記裏面側の端部から、前記第２方向における前記板状部材１１の外方に向かって延びる第２平板部１２ｂと、を有し、前記板状部材１１は、ブリネル硬さが１００以下である金属材料で構成され、前記Ｌ字状部材１２は、ブリネル硬さが１００を超える金属材料で構成される。【選択図】図２
