Description

【０００１】
【発明の属する技術分野】
本発明は、棒状の木材製法枠の保持装置、法面安定化構造及び法面安定化工法に関する。
【０００２】
【従来の技術】
近年、法面上に間伐材などの木材を使用して、法面を安定化させたり、緑化させる工法が提案されている。この工法は、法枠が木材で構成されるため、自然環境に適合的であり、また、木材として間伐材などの伐採木材を利用する場合は、資源の有効利用などに資する有用な工法である。
【０００３】
このような工法においては、法枠となる木材（本明細書では、単に木材製法枠ともいう。）を法面に保持する装置が必要となり、この保持装置としては、例えば、図１に示すものがある。
この保持装置１００は、各端部１０１ａ，１０１ａ…が開口する十字状、Ｌ字状又はＴ字状（図１では、十字状。）の筒体１０１からなっている。法枠の構築にあたっては、かかる保持装置１００をアンカーＶで法面Ｇに固定した後、各開口に順次木材製法枠Ｗを挿入し、もって法枠を構築する（例えば、特許文献１参照。）。
【特許文献１】
特開２００１−３２９５４１号公報
【０００４】
【発明が解決しようとする課題】
しかしながら、かかる保持装置１００には、以下のような問題がある。
すなわち、木材製法枠Ｗを筒体１０１の開口に挿入するにあたっては、木材製法枠Ｗを法面Ｇと平行な状態で法面Ｇ近傍に位置させ、そのまま法面Ｇと平行にスライドさせなければならない。したがって、かかる木材製法枠Ｗの開口への挿入作業は、大変な重労働となり、また、作業場所が傾斜面であることから、危険をともなうことにもなる。当然、何人もの作業員によって、かかる作業を行えば、かかる不都合は、減少するが、これでは、作業効率が著しく悪い。また、以上のような木材製法枠Ｗの挿入作業にあたって、かかる木材製法枠Ｗの径が大きい場合には、筒体１０１の開口の大きさに合わせて、削るなどの加工作業をなさなければならず、さらに作業効率が低下する。
【０００５】
そこで、本発明の主たる課題は、木材製法枠を法面に簡易に保持することができる木材製法枠の保持装置、法面安定化構造及び法面安定化工法を提供することにある。

下側保持部材及び上側保持部材が多孔性部材で形成されていると、保持装置が軽量となる。したがって、保持装置の運搬、固定作業などを行い易く、木材製法枠の保持作業効率を向上させることができる。
また、下側保持部材や上側保持部材の各孔を水や空気が通るので、法面を緑化する場合において、特に好適な保持装置となる。

木材製法枠を法面に保持するにあたっては、法面に木材製法枠の下側保持部材を固定し、この下側保持部材上に、木材製法枠の少なくとも一端部を載置した後、この載置部を木材製法枠の上側保持部材で覆う作業で足り、木材製法枠を法面と平行な状態で法面近傍に位置させ、そのまま法面と平行にスライドさせるという重労働は不要である。したがって、木材製法枠を法面に簡易に保持することができ、作業性に優れた法面安定化工法となる。
【００１８】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
〔第１の実施の形態〕
図２に第１の実施の形態に係る法面安定化構造１０を示した。本法面安定化構造１０は、法面Ｇに棒状の木材製法枠Ｗ，Ｗ…を格子状に組んだものである。格子状法枠の各格点１１，１１…においては、法面Ｇに対して、本実施の形態に係る木材製法枠の保持装置２０が固定されており、相互に左右又は上下に隣接する本保持装置２０，２０によって、木材製法枠Ｗの両端部Ｗａ，Ｗａが保持された構造になっている。
【００１９】
本実施の形態に係る保持装置２０は、法面Ｇに面して固定される木材製法枠Ｗの下側保持部材と、この下側保持部材に対向して固定される木材製法枠Ｗの上側保持部材と、に分離可能とされている。
具体的には、図３及び図４に示すように、下側保持部材２１は、法面Ｇに面して配される、真円形、楕円形、長方形などの適宜の形状の、本実施の形態では、正方形の平板２２と、この平板２２から法面Ｇ方向と反対方向（図３では、紙面手前方向。）に延在する掛止部２３，２３と、から主になる。この掛止部２３，２３は、平板２２上に木材製法枠Ｗが載置された場合において、この木材製法枠Ｗの載置部の法尻ＧＤ方向への移動（落下）を阻止するためのものである。したがって、その形状は特に限定されず、例えば、棒状とすることや、本実施の形態のようにＬ字状金具の一端面２３ａ，２３ａを利用するなどした面状とすることができる（本実施の形態では、Ｌ字状金具の他端面２３ｂ，２３ｂが平板２２に固定されている。）。また、掛止部２３，２３の配置位置は、木材製法枠Ｗをどのように載置するかに応じて、適宜設計する。本実施の形態では、支圧板２５の設けられた平板２２の略中央部に、アンカー挿通孔２４が形成されており、このアンカー挿通孔２４から両側方に延在する状態で、一対の木材製法枠Ｗ，Ｗが、その先端部Ｗａ，Ｗａが平板２２上に位置するように載置される（図１３の（３）参照）。そこで、掛止部２３，２３は、アンカー挿通孔２４の法尻側両側部に位置するように備えている。これにより、木材製法枠Ｗ，Ｗの先端部Ｗａ，Ｗａ（木材製法枠Ｗ，Ｗの載置部）の法尻ＧＤ方向への移動が阻止されることになる。したがって、本実施の形態に係る下側保持部材２１によると、相互に左右に隣接する下側保持部材２１，２１の、他の下側保持部材２１，２１側の掛止部２３，２３に、木材製法枠Ｗの両先端部Ｗａ，Ｗａを掛けるのみで、木材製法枠Ｗを仮保持することができるので、作業が著しく行い易くなる。また、本実施の形態の下側保持部材２１は、その上に載置される木材製法枠Ｗの重みをも利用して法面Ｇを圧するため、法面の安定化にも資する。
【００２０】
他方、図５〜図７に示すように、本実施の形態の上側保持部材３１は、別体とされた２つの保持体３２，３２から主になっており、この２つの保持体３２，３２を十字状に組み合わせて上側保持部材３１として使用するようになっている。
【００２１】
各保持体３２は、下側保持部材２１の平板２２に対向して配される略中央部にアンカー挿通孔３５が形成された長方形の覆い部３３と、この覆い部３３の側縁３３ａ，３３ａの前後両端部から法面Ｇ方向に延在する掛かり部３４，３４と、を主に有する。各保持体３２は、これら覆い部３３及び掛かり部３４，３４で、図７に示すように、断面略コ字状となっている。木材製法枠Ｗの保持作業にあたっては、かかるコ字状の保持体３２を、その内側に木材製法枠Ｗが位置するように、つまり木材製法枠Ｗを覆うように、配置し、固定する。この保持体３２の固定により、木材製法枠Ｗは、覆い部３３によって、法面Ｇ方向と反対方向への移動が阻止され、掛かり部３４，３４によって、木材製法枠Ｗの長手方向と直交する方向への移動が阻止される。
【００２２】
以上、本実施の形態では、上側保持部材３１を２つの部材（３２，３２）の組み合わせで構成したが、本発明の上側保持部材をこれに限る趣旨ではない。上側保持部材は、木材製法枠Ｗの法面Ｇ方向と反対方向への移動を阻止するためのものであるから（なお、本実施の形態では、木材製法枠Ｗの長手方向と直交する方向への移動をも阻止する構成となっている。）、例えば、３つ、４つ、あるいはそれ以上の部材の組み合わせによって構成することも、１つの部材のみによって構成することもできる。
【００２３】
次に、以上の本実施の形態の保持装置２０を使用して、木材製法枠Ｗを法面Ｇに保持する工法を、特に、格子状に組まれた法枠の格点１１，１１…部分について、施工手順に従って説明する。
まず、はじめに、図１３の（１）に示すように、法面Ｇに対して、基端部に図示しない雄ねじ部が形成されたアンカーＶを打ち込む。そして、このアンカーＶを利用して、前述した下側保持部材２１を固定する。この下側保持部材２１の固定は、図１３の（２）に示すように、下側保持部材２１の略中央部に形成されたアンカー挿通孔２４に前記アンカーＶを挿通させることにより行う。ただし、この工程は、例えば、まず、法面Ｇに面して下側保持部材２１を配し、この下側保持部材２１のアンカー挿通孔２４を挿通するように法面ＧにアンカーＶを打ち込むというように、その工程を逆転させることもできる。また、下側保持部材２１の材質によっては、下側保持部材２１として、アンカー挿通孔２４の形成されていないものを用いつつ、法面ＧにアンカーＶを打ち込むに際して、アンカーＶによって下側保持部材２１にアンカー挿通孔２４を形成することもできる。この他、下側保持部材２１の法面Ｇに対する固定を、アンカーＶを打ち込むという方法以外の方法によって、行うこともできる。
【００２４】
以上の作業が終了したら、次に、図１３の（３）に示すように、一対の木材製法枠Ｗ，Ｗを、その先端部Ｗａ，Ｗａが平板２２上に位置するように、アンカー挿通孔２４から両側方に延在する状態で、かつ木材製法枠Ｗの先端部Ｗａの法尻ＧＤ方向（紙面下側）への移動が阻止されるように、載置する。なお、木材製法枠Ｗの他方の先端部Ｗａは、左右に隣接する下側保持部材２１上に載置する。これにより、横方向に延在する木材製法枠Ｗ，Ｗが、仮保持された状態となる。
【００２５】
さらに、この仮保持作業が終了したら、次に、図１３の（４）に示すように、一対の木材製法枠Ｗ，Ｗを、その先端部Ｗａ，Ｗａが平板２２上に位置するように、かつアンカー挿通孔２４から法頭法尻方に延在する状態となるように、載置する。この際、アンカー挿通孔２４から法頭ＧＵ方向に延在する状態となる木材製法枠Ｗは、前記アンカー挿通孔２４から両側方に延在する木材製法枠Ｗ，Ｗの先端部Ｗａ，Ｗａによって、法尻ＧＤ方向への移動が阻止される。他方、アンカー挿通孔２４から法尻ＧＤ方向に延在する状態となる木材製法枠Ｗは、本下側保持部材２１の下方に隣接固定された下側保持部材２１（厳密には、木材製法枠Ｗの先端部Ｗａ。）によって、同様に、その法尻ＧＤ方向への移動が阻止される。
【００２６】
以上のようにしてアンカー挿通孔２４から上下（法頭ＧＵ，法尻ＧＤ）方向に延在する木材製法枠Ｗ，Ｗは、仮保持されるが、本実施の形態では、この仮保持をより確実なものとするために、図３及び図４に詳細に示すように、あらかじめ平板２２に支持材２７，２７…を設けている。この支持材２７，２７…は、平板２２から法面Ｇ方向と反対方向に延在しており、平板２２の法頭側端部及び法尻側端部に、法頭法尻方に延在する木材製法枠Ｗ，Ｗを挟む位置となるように、設けられている。本実施の形態においては、かかる支持材２７，２７…として、Ｌ字状金具を使用しており、その一端面２７ａ，２７ａ…が法面Ｇ方向と反対方向に延在し、他端面２７ｂ，２７ｂ…が平板２２に固定されている。加えて、かかるＬ字状金具の一端面２７ａ，２７ａ…には、図４に示すように、孔２７ｃ，２７ｃ…が形成されており、この孔２７ｃ，２７ｃ…を通して、釘などを適宜木材製法枠Ｗに打ち込むことができるようになっている。ただし、この釘などの打ち込みは、必須のものではなく、仮保持の確実性と作業の迅速性を利益衡量し、適宜行うとよい。
【００２７】
以上のようにして、木材製法枠Ｗ，Ｗ…を下側保持部材２１上に仮保持したら、次に、図１３の（５）及び（６）に示すように、上側保持部材３１の構成要素である上側保持体３２，３２を順次設置する。この設置は、上側保持体３２のアンカー挿通孔３５に、前記法面Ｇに打ち込んだアンカーＶが挿通されるように行う。そして、最後に、図１３の（７）に示すように、２つの上側保持体３２，３２から突出するアンカーＶの雄ねじ部（基端部）と、例えば、ナットなどの雌ねじ部材２８とを螺合する。この螺合により、格点１１における法面Ｇに対する上側保持部材３１及び下側保持部材２１の固定作業が、並びに木材製法枠Ｗの保持作業が完了する。
【００２８】
〔第２の実施の形態〕
以上、第１の実施の形態における法面安定化構造１０は、上下左右に各１本の木材製法枠Ｗが組まれた構造であった。しかし、本発明の法面安定化構造は、これに限られるものではなく、上下（法頭法尻）左右に各２本、３本、４本、あるいはそれ以上の複数の木材製法枠Ｗを組むこともできる。そこで、この複数の木材製法枠Ｗを組む構造を、第２の実施の形態として、以下、説明する。
【００２９】
図８に示すように、本実施の形態に係る法面安定化構造４０は、法頭法尻方向に各２本の木材製法枠Ｗ，Ｗが、左右方向に各１本の木材製法枠Ｗが、組まれた構造となっている。各格点４１，４１…においては、法面Ｇに対して、本実施の形態に係る保持装置５０，５０が固定されている。
【００３０】
本実施の形態に係る保持装置５０，５０のうち下側保持部材５１は、図９に示すように、基本的には、第１の実施の形態の保持装置２０と同じ構成である。ただし、法頭法尻方向に延在する木材製法枠Ｗを並列載置することができるように、掛止部２３，２３及び支持材２７，２７…が、両側方に離れた位置に設けられている。
【００３１】
これに対して、上側保持部材６１は、図１０〜１２に示すように、第１の実施の形態の上側保持部材３１とは大きく異なり、複数の部材からではなく、１つの部材からなっている。すなわち、この上側保持部材６１は、下側保持部材５１に対向して配される長方形の覆い部６２と、この覆い部６２の両側縁６２ａ，６２ａの前後両端部から法面Ｇ方向に延在する掛かり部６３，６３と、覆い部６２から側方に延在し、かつこの延在部から法面Ｇ方向に延在する第２の掛かり部６４，６４と、から主になる。使用にあたっては、かかる上側保持部材６１を、その長手方向が、上下方向に延在する木材製法枠Ｗ，Ｗの長手方向に沿うように配置し、固定する。この上側保持部材６１の固定により、覆い部６２によって、木材製法枠Ｗ（厳密には、先端部Ｗａ。）の法面Ｇ方向と反対方向への移動が阻止され、掛かり部６３，６３によって、法頭法尻方向に延在する木材製法枠Ｗの左右方向への移動が阻止され、第２の掛かり部６４，６４によって、左右方向に延在する木材製法枠Ｗの法尻方向への移動が阻止される。
【００３２】
次に、以上の第２の実施の形態の保持装置５０を使用して、木材製法枠Ｗを法面Ｇに保持する工法を、特に、格子状に組まれた法枠の格点４１，４１…部分について、説明する。
第２の実施の形態における格点の構造及び施工手順は、図１４に示すように、基本的には、第１の実施の形態と同様である。ただし、本形態では、図１４の（４）に示すように、法頭法尻方向に延在する木材製法枠Ｗ，Ｗを、各々並列に載置する。また、上側保持部材６１が、１つの部材で構成されているので、工程が減少し、若干作業が簡易化になる。なお、法頭法尻方向に延在する木材製法枠Ｗを並列にしない（１本とする）場合においても、本実施の形態のような１つの部材で構成された上側保持部材を使用することができる。
【００３３】
〔その他〕
（１）本発明において、木材製法枠は、例えば、間伐材などの木材を使用することができる。これらの木材は、適宜加工して棒状として、使用に供する。もちろん、はじめから法枠とするについて、適当な構造である場合は、加工不要である。
【００３４】
（２）以上の本実施の形態においては、各格点が十字状となる場合を示したが、これに限る趣旨ではない。例えば、各格点がＹ字状となる形態にも応用することができる。
【００３５】
（３）上側保持部材及び下側保持部材は、エキスパンドメタルや、パンチングメタル、金網などの多孔性部材とするのが好ましい。軽量化され、作業が容易となるためである。
【００３６】
（４）以上の本実施の形態においては、保持装置によって、木材製法枠の両端部を保持する構造を示したが、これに限る趣旨ではない。例えば、本発明の保持装置によって、木材製法枠の中央部のみを、あるいは両端部とともに中央部を保持する構造とすることもできる。
【００３７】
【発明の効果】
以上のとおり、本発明によれば、木材製法枠を法面に簡易に保持することができる木材製法枠の保持装置、法面安定化構造及び法面安定化工法となる。

BACKGROUND OF THE INVENTION
The present invention relates to a holding device for a rod-shaped wood manufacturing frame, a slope stabilization structure, and a slope stabilization method.
[0002]
[Prior art]
In recent years, methods have been proposed in which the slope is stabilized or greened using wood such as thinned wood on the slope. This method is suitable for the natural environment because the legal framework is made of wood, and it is a useful method that contributes to the effective use of resources when using thinned wood such as thinned wood as the wood. .
[0003]
In such a construction method, an apparatus for holding the timber to be used as a legal frame (also simply referred to as a timber manufacturing frame in the present specification) on a slope is required. As this holding apparatus, for example, one shown in FIG. There is.
The holding device 100 is composed of a cylindrical body 101 having a cross shape, an L shape, or a T shape (cross shape in FIG. 1) in which the end portions 101a, 101a,. In constructing the frame, after fixing the holding device 100 to the slope G with the anchor V, the wood frame W is sequentially inserted into each opening to construct the frame (see, for example, Patent Document 1). .
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2001-329541
[Problems to be solved by the invention]
However, the holding device 100 has the following problems.
That is, when the wood manufacturing frame W is inserted into the opening of the cylinder 101, the wood manufacturing frame W must be positioned in the vicinity of the slope G in a state parallel to the slope G and slid in parallel to the slope G as it is. Don't be. Therefore, the work for inserting the wood manufacturing method frame W into the opening is a heavy labor, and is dangerous because the work place is an inclined surface. Of course, if such a work is performed by a number of workers, such inconveniences are reduced, but the work efficiency is remarkably deteriorated. In addition, when inserting the wood manufacturing frame W as described above, if the diameter of the wood manufacturing frame W is large, a processing operation such as shaving must be performed in accordance with the size of the opening of the cylinder 101. In addition, the work efficiency is further reduced.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
[First Embodiment]
FIG. 2 shows the slope stabilizing structure 10 according to the first embodiment. This slope stabilization structure 10 is constructed by assembling rod-like wood manufacturing frames W, W. In each of the grid-like method frames 11, 11..., The wood manufacturing method frame holding device 20 according to the present embodiment is fixed to the slope G, and the books adjacent to each other on the left and right or top and bottom. Both ends Wa and Wa of the wood manufacturing method frame W are held by the holding devices 20 and 20.
[0019]
The holding device 20 according to the present embodiment includes a lower holding member of the wood manufacturing frame W that is fixed facing the slope G, and an upper side of the wood manufacturing frame W that is fixed to face the lower holding member. It can be separated into the holding member.
Specifically, as shown in FIGS. 3 and 4, the lower holding member 21 has an appropriate shape such as a perfect circle, an ellipse, or a rectangle arranged facing the slope G. In the form, it is mainly composed of a square flat plate 22 and latching portions 23, 23 extending from the flat plate 22 in the direction opposite to the normal plane G direction (the front side in FIG. 3). When the wood manufacturing frame W is placed on the flat plate 22, the latching portions 23 and 23 prevent movement (falling) of the placing portion of the wood manufacturing frame W in the direction of the bottom edge GD. Is. Therefore, the shape is not particularly limited, and can be, for example, a bar shape or a surface shape using one end surfaces 23a, 23a of the L-shaped metal fitting as in the present embodiment (this embodiment). In this embodiment, the other end surfaces 23b, 23b of the L-shaped metal fitting are fixed to the flat plate 22. Further, the arrangement positions of the latching portions 23 and 23 are appropriately designed according to how the wood manufacturing method frame W is placed. In the present embodiment, an anchor insertion hole 24 is formed at a substantially central portion of the flat plate 22 on which the bearing plate 25 is provided, and a pair of wood manufacturing methods extends from the anchor insertion hole 24 to both sides. The frames W and W are placed so that the front end portions Wa and Wa are positioned on the flat plate 22 (see (3) in FIG. 13). Therefore, the latching portions 23, 23 are provided so as to be located on both sides of the anchor butt side of the anchor insertion hole 24. As a result, the movement of the front end portions Wa and Wa of the wood manufacturing frames W and W (the placement portions of the wood manufacturing frames W and W) in the direction of the method bottom GD is prevented. Therefore, according to the lower holding member 21 according to the present embodiment, the hooks 23 and 23 on the other lower holding members 21 and 21 side of the lower holding members 21 and 21 adjacent to each other on the left and right are Since the wood manufacturing frame W can be temporarily held only by hooking both the end portions Wa, Wa of the wood manufacturing frame W, the operation is significantly facilitated. In addition, the lower holding member 21 of the present embodiment presses the slope G using the weight of the wood manufacturing frame W placed thereon, which contributes to stabilization of the slope.
[0020]
On the other hand, as shown in FIG. 5 to FIG. 7, the upper holding member 31 of the present embodiment is mainly composed of two holding bodies 32, 32 that are separated from each other, and these two holding bodies 32, 32. Are combined in a cross shape and used as the upper holding member 31.
[0021]
Each holding body 32 includes a rectangular covering portion 33 in which an anchor insertion hole 35 is formed at a substantially central portion arranged to face the flat plate 22 of the lower holding member 21, and side edges 33 a and 33 a of the covering portion 33. And mainly have hook portions 34, 34 extending in the direction of the slope G from both front and rear end portions. As shown in FIG. 7, each holding body 32 has a substantially U-shaped cross section as shown in FIG. When holding the wood manufacturing frame W, the U-shaped holding body 32 is arranged and fixed so that the wood manufacturing frame W is located inside, ie, covers the wood manufacturing frame W. By fixing the holding body 32, the wood manufacturing frame W is prevented from moving in the direction opposite to the slope G direction by the cover portion 33, and is orthogonal to the longitudinal direction of the wood manufacturing frame W by the hook portions 34 and 34. Movement in the direction is prevented.
[0022]
As mentioned above, in this Embodiment, although the upper side holding member 31 was comprised by the combination of two members (32, 32), the meaning of the upper side holding member of this invention is not restricted to this. The upper holding member is for preventing the movement of the wood manufacturing frame W in the direction opposite to the direction of the slope G (in the present embodiment, in the direction orthogonal to the longitudinal direction of the wood manufacturing frame W).

On the other hand, the wood manufacturing frame W that extends from the anchor insertion hole 24 in the direction of the method bottom GD is a lower holding member 21 (strictly speaking, a wood manufacturing frame that is adjacently fixed below the lower holding member 21). Similarly, the leading end portion Wa of W) prevents the movement in the direction of the trailing edge GD.
[0026]
As described above, the wood manufacturing frames W and W extending in the vertical direction (the head GU and the tail GD) from the anchor insertion hole 24 are temporarily held. In the present embodiment, this temporary holding is further performed. In order to make sure, as shown in detail in FIGS. 3 and 4, support members 27, 27... Are provided on the flat plate 22 in advance. The support member 27, 27 ... extends from the flat plate 22 in the opposite direction to the slope direction G, the Hoatama end and law trailing edge of the flat plate 22, extending Hoatama method buttocks side It is provided so that it may become the position which pinches | interposes the wood manufacturing frame W and W to do. In the present embodiment, L-shaped metal fittings are used as the support members 27, 27, etc., and one end surfaces 27a, 27a,... Extend in the direction opposite to the slope G direction, and the other end surfaces 27b, 27 b... Are fixed to the flat plate 22. In addition, as shown in FIG. 4, holes 27c, 27c,...
