PRESSURE PLATE AND SLOPE PROTECTION SYSTEM
PROBLEM TO BE SOLVED: To provide a pressure plate that inhibits breaking of a net-like body due to stress concentration on a mesh part of the net-like body, the net-like body being in contact with a side part of an anchor underneath the pressure plate.SOLUTION: A pressure plate 10 has a body part 12 fitted on an anchor 18 from above a net-like body 20 stretched on a slope surface. The pressure plate 10 has one or a plurality of protrusions 16a to 16d protruding from one side surface 12e when the pressure plate is fitted on the anchor 18, the protrusions inserted into meshes of the net-like body 20 other than at least that into which the anchor 18 is inserted, and a side part of the protrusions 16a to 16d is in a close proximity at least of a corner 23a of the mesh at an uppermost part of the slope surface and a corner 23b of the mesh at a lowermost part of the slope surface. Thus, when the net-like body is pulled upward (in a direction of arrow H) or downward (in a direction of arrow L) in a direction of slope inclination, stresses exerted on the net-like body 20 are dispersed toward the corner 23a and the corner 23b, reducing possibility of the net-like body 20 being broken at a portion where the anchor 18 and the net-like body 20 come in contact with each other.SELECTED DRAWING: Figure 6
【課題】受圧板下部においてアンカーの側部に当接する網状体の網目部位への応力集中による網状体の破断を抑制しうる受圧板を提供する。【解決手段】斜面に展設された網状体２０の上方から本体部１２がアンカー１８に取り付けられる受圧板１０である。受圧板１０は、アンカー１８への取付け状態で、一方の面１２ｅから突出して網状体２０の少なくともアンカー１８が挿通される網目とは別の網目内に挿通される一又は複数の突起部１６ａ〜１６ｄを有し、且つ突起部１６ａ〜１６ｄの側部は少なくとも上記網目における斜面最上部の角部２３ａ及び斜面最下部の角部２３ｂに近接する。これにより、斜面傾斜方向上方（Ｈ矢視方向）及び下方（Ｌ矢視方向）に網状体が引っ張られた場合、網状体２０に作用する応力が角部２３ａ及び角部２３ｂにそれぞれ分散し、アンカー１８と網状体２０との当接部位における網状体２０の破れのおそれが低減する。【選択図】図６
