モルタルを吹付けること等が行なわれている。(Prior art) Conventionally, as a method for reinforcing sloped ground such as a slope,
Efforts include constructing concrete legal frameworks on the ground and spraying mortar over the entire slope.
(本発明が解決しようとする問題点)
しかし、コンクリートの法枠を施設する方法は、鉄筋の
組付けや型枠の仮設を要し、しかもそれらが鋼製の資材

、膨張し、法枠の劣化を招き、当初の目的が果せなくな
る、という問題がある。(Problems to be solved by the present invention) However, the method of constructing a concrete legal framework requires the installation of reinforcing bars and temporary construction of formwork, and since these materials are made of steel, they are heavy. However, it has the disadvantage that construction is difficult and inefficient, especially on slopes where workability is poor.
Because the preparation materials are buried in the framework, there may be damage due to insufficient concrete cover or cracks in the concrete, natural influences such as rainwater, and man-made environmental influences such as exhaust gas. There is a problem in that the steel materials corrode and expand, leading to deterioration of the legal framework and making it impossible to achieve its original purpose.
また、モルタルを吹付ける方法では、モルタルの強度が
弱いため、法面を完全に押える効果が乏しいとともに、
法面と吹付は而とが#離するようになるため、度々補修
を要するといった欠点がある。In addition, with the method of spraying mortar, the strength of the mortar is weak, so it is not effective in completely suppressing the slope, and
The problem is that the slope and the sprayed surface become separated from each other, requiring frequent repairs.
本発明は、前記のような従来技術による欠点を改善し、
重量の大きな鉄筋や型枠などの資材を使用することなく

本発明においては、ぎ法面上への施設材として、第2図
に示すような網状法枠板Aを使用する。In the present invention, a net-like slope frame board A as shown in FIG. 2 is used as a construction material on the slope surface.
この網状法枠板Aは、細い線状材を互に交差して形成し
た網状板lと、これに一体化して形成した太い線状板に
よる軸筋2.2とを備えている。網状板l及び軸筋2を
形成する線状材は、軽信で高い強度を有する繊維に高耐
腐蝕性の樹脂材料を含浸した繊維束を用いて成形、硬化
させて形成する。This net-like frame plate A includes a net-like plate l formed by intersecting thin wire members, and an axial reinforcement 2.2 made of a thick linear plate integrally formed therewith. The wire members forming the mesh plate 1 and the shaft reinforcement 2 are formed by molding and curing a fiber bundle made of lightweight, high-strength fibers impregnated with a highly corrosion-resistant resin material.
前述の繊維としては、ガラス繊維やカーボン繊維などが
好適であるが、その他、例えば合成樹脂繊維、セラミッ
ク繊維など、或はそれらの繊維を適宜組合わせたものが
使用可能である。The aforementioned fibers are preferably glass fibers, carbon fibers, etc., but other materials such as synthetic resin fibers, ceramic fibers, or a suitable combination of these fibers can also be used.
また、その繊維を結束する樹脂材料としては、繊維に対
する接着性がよく、かつそれ自体でも充分な強度を持つ
、例えばビニルエステル樹脂などが好適であり、その他
、不飽和ポリエステル樹脂、エポキシ樹脂、フェノール
樹脂などを挙げることができる。In addition, as the resin material for binding the fibers, it is preferable to use vinyl ester resin, which has good adhesion to the fibers and has sufficient strength by itself, for example, unsaturated polyester resin, epoxy resin, phenol resin, etc. Examples include resin.
なお、線状材は、前記のような、繊維に樹脂を含浸して
成形したものに限定されるものではなく、合成樹脂材だ
けで形成することもできる。Note that the linear material is not limited to the above-mentioned material formed by impregnating fibers with a resin, but may also be formed only from a synthetic resin material.
それで、網状法枠板Aの網状板■には、格子状に所要高
さの隆起条3,3が形成されており、その上部に、隆起
条3の長平方向、即ち頂稜に沿って、太い線状材による
軸筋2が縦走し、その軸筋2と網状板1を形成する細い
線状材゛とは互に交差一体化し、さらに、交差した軸筋
2゜2も互にそれらの交差個所で一体化されている。Therefore, raised strips 3, 3 of a required height are formed in a lattice pattern on the mesh plate (2) of the mesh frame board A, and on the upper part thereof, along the longitudinal direction of the raised strips 3, that is, along the top edge. Axial reinforcements 2 made of thick wire materials run longitudinally, and the shaft reinforcements 2 and the thin wire materials forming the mesh plate 1 intersect and integrate with each other, and furthermore, the crossed shaft reinforcements 2. They are integrated at intersections.
したがって、網状法枠板Aは、頂稜に軸筋2゜2を有す
る隆起条3が格子状に形成され、隆起条3に囲まれた中
には、軸筋2より低く凹んだ網状板部分1a、Iaがそ
れぞれ形成された形となる。Therefore, the mesh-like frame board A has raised strips 3 having shaft bars 2°2 at the top edges formed in a lattice shape, and surrounded by the raised strips 3 is a reticular plate portion recessed lower than the shaft bars 2. 1a and Ia are respectively formed.
上記構成の網状法枠板Aは、工場において製作されて、
現場に搬入し、法面上に敷設される。The mesh frame board A having the above configuration is manufactured in a factory,
It is delivered to the site and laid on the slope.
法面地山への固定は、例えば軸筋2,2の交差個所或は
他の適所を地山に打設のアンカー(図示を略す)と結合
して行なう。Fixing to the slope ground is carried out, for example, by connecting the intersection of the shaft reinforcements 2, 2 or other suitable locations with anchors (not shown) cast into the ground.
法面への網状法枠板Aの施設後は、その上より、コンク
リートやモルタル或はポーラスコンクリート等のコンク
リート類Bを打設(吹付けを含む)し、網状法枠板Aを
コンクリート類B中に埋設する。それによって、法面上
はコンクリート類Bによる被覆層4が形成されると共に
、隆起条3.3の形状に沿って格子状に隆起したコンク
リート法枠5が形成されることになるのである。After installing the mesh method frame board A on the slope, concrete type B such as concrete, mortar, or porous concrete is poured (including spraying) on top of it, and the mesh method frame board A is replaced with concrete type B. bury it inside. As a result, a covering layer 4 of concrete B is formed on the slope, and a raised concrete slope frame 5 is formed in a lattice shape along the shape of the raised strips 3.3.
なお、この場合、コンクリート類Bの打設は、第3図に
示すように、隆起条3の部分に対し行なって、コンクリ
ート法枠5だけを形成することもできる。In this case, as shown in FIG. 3, the concrete type B can be placed on the raised strips 3 to form only the concrete slope 5.
また、隆起条3の形状は前記実施例では断面三角状とな
っているが、第4図に示したように断面方形状でもよく
、さらに、軸筋2は隆起条2に複数配列してもよい。Further, although the raised strip 3 has a triangular cross section in the above embodiment, it may have a rectangular cross section as shown in FIG. good.
前記実施例において、網状法枠板Aは、広い面積のもの
に形成したものを例示しているが、その生産と運搬の事
情から定尺の乙のを製作して現場で継ぎ合せて施工する
ことになる。そのため、本発明においては、第5図に示
すように、網状法枠板A′を一つの枠板単位に形成し、
その単位枠板A°の多数を現場で継続させて施設するよ
うにすれば、生産及び運搬上−層好適である。In the above example, the reticulated frame board A is formed to have a wide area, but due to the circumstances of production and transportation, it is necessary to manufacture a set of standard size boards and join them together on site. It turns out. Therefore, in the present invention, as shown in FIG. 5, the mesh frame plate A' is formed into one frame plate unit,
It is convenient for production and transportation if a large number of unit frame plates A° are installed continuously on site.

できる。(Effects of the Invention) As explained above, the construction method of the present invention impregnates lightweight and high-strength fibers with a highly corrosion-resistant resin material, and integrally forms thin wires by intersecting each other. On the reticular plate made of
The raised stripes are formed in a grid pattern, and at the top of each raised strip,
Arranging an axial reinforcement made of the thick wire material along the long plane direction, and integrating the axial reinforcement and the mesh plate to form a mesh frame board,
This mesh method frame board was laid on the slope ground, concrete was poured on top of it, and the mesh method frame board was buried in the concrete. With the extremely simple process of pouring concrete from above, a legal frame structure or a protective layer can be constructed in addition to it, without the need for temporary formwork as in the past. Since the shaft reinforcements are buried, the shaft reinforcements are integrally cross-connected to each other, and the shaft reinforcements are integrally connected to the mesh plate, the slope frames are interconnected and a strong slope structure is constructed. can.

きる等、多くの優れた効果を奏するものである。In addition, the formwork that is buried and also used for reinforcing is corrosion resistant, so there is almost no need to use steel materials.
There is no fear that the buried material will corrode due to natural influences such as rainwater or man-made influences such as exhaust gas, leading to deterioration of the structure, and the structure can be stabilized for a long time. When concrete is placed only on the raised stripes or when porous concrete is placed, many excellent effects can be achieved, such as the ability to create vegetation and greening.
