【考案の詳細な説明】
本考案は山肌傾斜面の落石防止ネットの張設等のために
岩盤に打ち込んで使用される基礎杆に関するもので、岩
盤上に表土層がある場合に、この表土層中に埋入された
部分での曲がりを最小限に抑制できるようにせんとする
ものである。[Detailed description of the invention] This invention relates to a foundation rod that is driven into bedrock to install rock fall prevention nets on mountain slopes. The aim is to minimize bending at the part embedded inside.
以下、本考案の実施例を図に依拠して説明する。Embodiments of the present invention will be described below with reference to the drawings.
１は軸体で、この軸体１には管体２とこれの下部におい
て拡張筒体３がそれぞれ外嵌されている。Reference numeral 1 denotes a shaft body, and a tube body 2 and an expansion cylinder 3 are fitted onto the shaft body 1 at the lower part thereof.
拡張筒体３は周壁に複数の摺り割り３１を有し、該筒体
３の上部に管体２の下端部が挿入されている。The expansion cylinder 3 has a plurality of slots 31 in its peripheral wall, and the lower end of the tube 2 is inserted into the upper part of the cylinder 3.
４は締付ナツトで、筒体３の上端面に接して軸体１の上
端雄ネジ部１１に螺合されている。Reference numeral 4 denotes a tightening nut which is in contact with the upper end surface of the cylindrical body 3 and is screwed into the upper end male threaded portion 11 of the shaft body 1.
この締付ナツト４の上部には、二枚の座金５，６が互い
の間にスペーサ７を介して取着され、ロックナツト８で
゛固定される。Two washers 5 and 6 are attached to the upper part of the tightening nut 4 with a spacer 7 interposed therebetween, and fixed with a lock nut 8.
９は土圧抵抗板で、裏面に筒状部９１を有し、この筒状
部９１を介して管体３に着脱自在に取付けられる。Reference numeral 9 denotes an earth pressure resistance plate, which has a cylindrical portion 91 on its back surface, and is detachably attached to the tubular body 3 via this cylindrical portion 91.
なお、筒状部９１の内径寸法は締付ナツト４の外径寸法
よりも大きく形成され、該ナツト螺着状態のまま筒状部
９１が管体３に嵌合されうるようになっている。The inner diameter of the cylindrical portion 91 is larger than the outer diameter of the tightening nut 4, so that the cylindrical portion 91 can be fitted into the tube body 3 while the nut is screwed.
また、土庄抵抗板９の左右両側は表側に折曲され、この
折曲部９２．９２が補強効果を果すと同時に、土中に喰
い込んで抵抗板９を安定させる作用をなす。Further, both left and right sides of the Tonosho resistance plate 9 are bent toward the front side, and the bent portions 92 and 92 have a reinforcing effect and, at the same time, work to stabilize the resistance plate 9 by digging into the soil.
この基礎杆を使用するときには、岩盤Ａに予備孔を穿設
してこれに該基礎杆を打ち込む。When using this foundation rod, a preliminary hole is drilled in the bedrock A and the foundation rod is driven into this.
この際、土庄抵抗板９および座金５，６、スペーサ７、
ロックナツト８は取外しておく。At this time, the Tonosho resistance plate 9, washers 5, 6, spacer 7,
Remove lock nut 8.
こうして、基礎拝上端部のみが表土層Ｂから突出する状
態となるまで打ち込んだ後、締付ナツト４を締付けて管
体２を降下させ、その下端部を拡張筒体３に圧入させる
。After driving the foundation until only the upper end of the foundation protrudes from the topsoil layer B, the tightening nut 4 is tightened to lower the pipe body 2, and its lower end is press-fitted into the expansion cylinder body 3.
こうすれば、該筒体３が拡開して岩盤Ａ内で強固に固定
され、もって基礎杆全体が抜は止めされる。In this way, the cylindrical body 3 is expanded and firmly fixed within the rock mass A, thereby preventing the entire foundation rod from being pulled out.
この後、土圧抵抗板９を管体２に取着して表土層Ｂ中に
埋設する。Thereafter, the earth pressure resistance plate 9 is attached to the tube body 2 and buried in the topsoil layer B.
この場合、該抵抗板９は、筒状部９１を管体２に嵌合さ
せた状態で土中に打ち込んでもよいし、前もって上面を
適当深さに掘り、抵抗板９を管体２に取着した状態で降
下させて土を埋め戻してもよい。In this case, the resistance plate 9 may be driven into the soil with the cylindrical portion 91 fitted into the tube body 2, or the upper surface may be dug to an appropriate depth in advance and the resistance plate 9 is attached to the tube body 2. It is also possible to lower the soil and backfill with soil.
また、同抵抗板９は荷重作用方向に向けて土中に埋設す
る。Further, the resistance plate 9 is buried in the soil facing the direction of load application.
なお、抵抗板埋込後、座金５，６、スペーサ７、ロック
ナツト８を取付け、座金５，６間に落石防止ネットの張
索等を止めつける。After embedding the resistance plate, the washers 5 and 6, the spacer 7, and the lock nut 8 are installed, and a rock fall prevention net rope or the like is fastened between the washers 5 and 6.
かかる状態で本基礎杆を使用すれば、該杆の表土層Ｂ内
に位置する部分に大きな曲げ荷重Ｐが作用しても、該荷
重に対して土圧抵抗板９による大きな土庄抵抗が反力と
して作用するため、基礎杆の曲がりが最小限に抑制され
る。If this foundation rod is used in such a state, even if a large bending load P acts on the portion of the rod located in the topsoil layer B, the large bending resistance by the earth pressure resistance plate 9 will be a reaction force against the load. Since the bending of the foundation rod is suppressed to a minimum.
このため、たとえば落石防止ネットが大きく移動したり
部分的にゆるんだりする危険性がなくなる。This eliminates the risk of the rock fall prevention net moving significantly or becoming partially loosened, for example.
なお、上記実施例では土圧抵抗板９を管体２と別体とし
たから、基礎杼打ち込み時には上記したように抵抗板９
を取外しておくことによって、表土層Ｂから受ける打ち
込７六抵抗が少なくてすむ。In the above embodiment, the earth pressure resistance plate 9 is made separate from the pipe body 2, so when driving the foundation shuttle, the resistance plate 9 is
By removing it, the driving resistance received from the topsoil layer B can be reduced.
また、同抵抗板９を荷重作用方向に向けてｊＥ確（、−
セラ１へし易い。Also, with the same resistance plate 9 facing the direction of load application,
Easy to change to Sera 1.
さらに、表−上層Ｂがない現場においては従前通り土圧
抵抗板９を除外した状態で使用することができる。Furthermore, at sites where there is no surface-upper layer B, it can be used without the earth pressure resistance plate 9 as before.
一方、管理面において（＋ １．＋−ＩｇＥ抵抗板９を
装着、非装塙いずれの状態でも収納、保管または運搬で
きるため便利となり、また製造面でも、抵抗板付きと抵
抗板なしの〆別を一つける必要がないため有利どなる。On the other hand, in terms of management (+ 1.+-IgE resistance plate 9 can be stored, stored, or transported with or without it, it is convenient, and in terms of manufacturing, it is possible to differentiate between with and without a resistance plate. It is advantageous because there is no need to attach one.
但し、本考案においては、上圧抵抗板９を管体２に一体
に固着しておいてもよく、こうしても、曲がり抑制効果
に些かも遜色はない。However, in the present invention, the upper pressure resistance plate 9 may be integrally fixed to the tube body 2, and even if this is done, the effect of suppressing bending is not inferior in the slightest.
また、同抵抗板９の形状および大きさは実施にあたり適
宜選択しうるどころである。Furthermore, the shape and size of the resistor plate 9 can be selected as appropriate for implementation.
ト、記のように本考案の基礎杆によれば、表土層に覆わ
ｉ′した岩盤に打ち込んて゛使用する場合に、土圧抵抗
板によって、表土層に埋入された部分の曲がりを最小限
に抑制することができる。According to the foundation rod of the present invention, as described in G and D, when used by driving it into rock covered with a topsoil layer, the earth pressure resistance plate minimizes the bending of the part embedded in the topsoil layer. can be suppressed to
このため、落石防ＩＬネット等０支持状態の安定性を向
上さゼ゛ることかできるものである。Therefore, it is possible to improve the stability of the zero support state, such as a rock fall prevention IL net.
