ANCHOR PRESSURE PLATE
To surely press a slope even with a branch-like pressure portion extending branch-like from a central pressure portion through which an anchor material is passed.SOLUTION: An anchor pressure plate 1 that transmits the tension force of a rock bolt 2 to the ground, when an end of the rock bolt 2 protruding from the ground is tightened with a tightening nut 3, comprises a pressure plate body 11 having a central pressure portion 11a provided with a bolt through hole 11a1 through which the rock bolt 2 is passed, and a plurality of branch-like pressure portions 11b extending outward from the central pressure portion 11a in a branch shape, and a stress transmitting member 12 that is provided with the bolt through hole 11a1 through which the rock bolt 2 is passed, and presses the central pressure portion 11a and the plurality of branch-like pressure portions 11b of the pressure plate body 11 by tightening the tightening nut 3.SELECTED DRAWING: Figure 1
【課題】アンカー材が通される中央受圧部から枝状に延びる枝状受圧部でも斜面を確実に押圧する。【解決手段】地盤から突出したロックボルト２の端部を緊結ナット３で緊結した際のロックボルト２の緊張力を当該地盤に伝達するアンカー用受圧板１であって、ロックボルト２が通されるボルト通し孔１１ａ１が設けられた中央受圧部１１ａおよびその中央受圧部１１ａから外側に向かって枝状に延びる複数の枝状受圧部１１ｂを有する受圧板本体１１と、ロックボルト２が通されるボルト通し孔１１ａ１が設けられ、緊結ナット３の緊結によって受圧板本体１１の中央受圧部１１ａおよび複数の枝状受圧部１１ｂを押圧する応力伝達部材１２とを備える。【選択図】図１
