ところで、現行の土木基準では、前記格子状鉄筋を覆うモルタル等の厚み（こ れを被り厚という）が鉄筋のどの面からも５ｃｍ以上であることが、所要強度の 格子状法枠を得るための品質管理基準として義務付けられている。しかしながら 、前記現場打ち法枠工法は、型枠を用いない現場打ち法枠工法であるとともに、 モルタル等の吹き付けは、法面上の不安定な場所で現場作業として行われること から、格子状鉄筋に対するモルタル等の吹付け厚さや幅が不均一となりやすく、 所定寸法の格子状法枠を形成するのに相当の熟練度を要するとともに、格子状法 枠の寸法や強度にバラツキを生じることを避けることができなかった。 By the way, according to the current civil engineering standards, the thickness of mortar, etc. that covers the grid-like reinforcing bars (this is called the covering thickness) is 5 cm or more from any surface of the reinforcing bars in order to obtain the grid-like frame with the required strength. Is required as a quality control standard. However, the above-mentioned cast-in-place method method is a cast-in-place method method that does not use a formwork, and spraying mortar etc. is performed as an on-site operation in an unstable place on the slope. The thickness and width of mortar etc. sprayed on the mortar are likely to be non-uniform, and considerable skill is required to form a grid-like method frame of a predetermined size, and variations in the size and strength of the grid-like method frame are avoided. I couldn't.

The first member 1, the second member 2 and the reinforcing bar holding member 3 which constitute the inspection frame K are made of, for example, a wire of an appropriate thickness that has been rust-proofed, and the first member and the second member 2 Are connected by welding or soldering. Further, the reinforcing bar holding member 3 is welded to, for example, the pair of leg portions 1B of the first member 1 so as to connect them. Therefore, the inspection frame K has a simple structure, is easy to manufacture, and is inexpensive.
【０００８】 そして、法面５に所定のモルタルなどよりなる格子状法枠１２を形成するに際 しては、法面５を整形した後、図１に示すように、法面５全体に菱形金網などの 網状体６を敷設し、この網状体６上に鉄筋８を格子状に配置する。そして、図２ に示すように、第１部材１が鉄筋８を跨ぎ、かつ、鉄筋８が上辺１Ａと鉄筋保持 部材３との間に位置するように、つまり、鉄筋８を、上辺１Ａと鉄筋保持部材３ とによって形成される空間９を挿通させるようにして、検測枠Ｋを網状体６上に 適宜の間隔をおいて配置し、その後、図１および図３に示すように、格子枠を形 成する鉄筋８にモルタルなど１１を吹き付けるのである。Then, when forming the lattice-shaped method frame 12 made of a predetermined mortar or the like on the slope 5, after shaping the slope 5, as shown in FIG. A mesh body 6 such as a wire mesh is laid, and the reinforcing bars 8 are arranged on the mesh body 6 in a grid pattern. As shown in FIG. 2, the first member 1 straddles the reinforcing bar 8 and the reinforcing bar 8 is located between the upper side 1A and the reinforcing bar holding member 3, that is, the reinforcing bar 8 is connected to the upper side 1A and the reinforcing bar 8. The inspection frames K are arranged on the mesh 6 at appropriate intervals so that the space 9 formed by the holding member 3 is inserted therethrough, and then, as shown in FIG. 1 and FIG.

【００１０】[0010]
図１〜図４は、この考案の検測枠およびこれを用いる法枠工法の一例を示すも のである。まず、図４において、Ｋは検測枠で、この検測枠Ｋは、所定の高さＨ （例えば１０ｃｍ）と幅Ｗ（例えば３０ｃｍ）とを有する一対の第１部材１と、 この第１部材１どうしを連結する第２部材２と、第１部材１の高さ方向中間部に おいて第１部材１に一対の脚部１Ｂを結ぶ方向に横設される鉄筋保持部材３とか ら構成されている。 1 to 4 show an example of an inspection frame of this invention and a method frame method using the same. First, in FIG. 4, K is an inspection frame, and this inspection frame K includes a pair of first members 1 having a predetermined height H (for example, 10 cm) and a width W (for example, 30 cm), and the first member. It is composed of a second member 2 that connects the members 1 and a reinforcing bar holding member 3 that is provided in the middle of the height direction of the first member 1 in a direction connecting the pair of legs 1B to the first member 1. Has been done.
【００１１】 すなわち、第１部材１、第２部材２および鉄筋保持部材３は、例えば防錆加工 を施した適宜太さ（例えば直径４ｍｍ）の針金よりなる。第２部材２の両端部は 、溶接またはハンダ付けによって第１部材１の下端部よりやや上方位置に固着さ れている。そして、この実施例においては、第１部材１の両下端部を適宜長さ（ 例えば３ｃｍ程度）例えば互いに向き合う方向に折曲して沈み防止部４を形成し ている。なお、第２部材２の長さＬは、法面５に鉄筋８によって形成される格子 枠の一つの辺の長さよりも短く、例えば３０ｃｍ程度でよい。That is, the first member 1, the second member 2 and the reinforcing bar holding member 3 are made of, for example, a wire having an appropriate thickness (for example, a diameter of 4 mm) that has been rust-proofed. Both ends of the second member 2 are fixed to a position slightly above the lower end of the first member 1 by welding or soldering. Then, in this embodiment, both the lower end portions of the first member 1 are bent to have an appropriate length (for example, about 3 cm), for example, in the directions facing each other to form the sinking prevention portion 4. The length L of the second member 2 may be shorter than the length of one side of the lattice frame formed by the reinforcing bars 8 on the slope 5 and may be, for example, about 30 cm.
【００１１】 次に、上記検測枠Ｋを用いて行う現場打ち法枠工法の一例について、図１〜図 ３を参照しながら説明する。予め整形された法面５に目合いが例えば５〜６ｃｍ 程度の菱形金網などの網状体６を敷設し、アンカ−７を適宜の間隔で法面５に打 ち込んで網状体６を法面５に固定する（図２および図３参照）。Next, an example of the in-situ casting method frame construction method using the inspection frame K will be described with reference to FIGS. 1 to 3. A mesh body 6 such as a diamond wire mesh having a mesh size of about 5 to 6 cm is laid on the pre-shaped slope 5, and anchors 7 are driven into the slope 5 at appropriate intervals to form the slope 6. 5 (see FIGS. 2 and 3).
【００１２】 前記網状体６の上に例えば直径が６〜１０ｍｍ程度の鉄筋８を一辺が１〜２ｍ 程度の格子状に組み合わせて配置する（図１参照）。Reinforcing bars 8 having a diameter of, for example, about 6 to 10 mm are combined and arranged on the net-like body 6 in a lattice shape having one side of about 1 to 2 m (see FIG. 1).
【００１３】 そして、鉄筋８からなる格子枠の各辺のほぼ中央に、第１部材１が鉄筋８を跨 ぎ、かつ、鉄筋８が上辺１Ａと鉄筋保持部材３との間に位置するように、つまり 、鉄筋８が上辺１Ａと鉄筋保持部材３とによって形成される空間９を挿通させる ようにして、検測枠Ｋを網状体６上に適宜の間隔をおいて配置する（図１および 図２参照）。この場合、第１部材１の下端に沈み防止部４が形成されているので 、法面５が盛土であるような場合、検測枠Ｋが法面５から沈み込むことが防止さ れる。なお、必要により、適宜の結束線１０を用いて鉄筋８を鉄筋保持部材３に 結束してもよい（図２および図３参照）。Then, the first member 1 straddles the reinforcing bar 8 and the reinforcing bar 8 is positioned between the upper side 1 A and the reinforcing bar holding member 3 at approximately the center of each side of the lattice frame composed of the reinforcing bars 8. That is, the inspection frames K are arranged on the mesh body 6 at appropriate intervals so that the reinforcing bars 8 are inserted into the space 9 formed by the upper side 1A and the reinforcing bar holding member 3 (FIG. 1 and FIG. 2). In this case, since the sinking prevention portion 4 is formed at the lower end of the first member 1, the inspection frame K is prevented from sinking from the slope 5 when the slope 5 is embankment. If necessary, the reinforcing bar 8 may be bound to the reinforcing bar holding member 3 by using an appropriate binding wire 10 (see FIGS. 2 and 3).
【００１４】 前記検測枠Ｋは、モルタル等１１の吹き付け幅および吹き付け高さの目安とな るものであるから、格子枠の各辺に少なくとも一つ設けてあればよく、この実施 例のように、辺の長さが１〜２ｍ、検測枠Ｋの長さＬが３０ｃｍのときは、各辺 に一つの検測枠Ｋを設けるだけでよい。また、前記辺の長さがより大きくなった ときは、前記寸法の検測枠Ｋを２以上設けてもよいが、検測枠Ｋの長さＬをより 大きく（例えば１．３〜１．５ｍ程度）設定してもよい。さらに、検測枠Ｋを辺 全長に亘って設けてもよい。Since the inspection frame K serves as a guide for the spraying width and spraying height of the mortar 11 and the like, it is sufficient to provide at least one on each side of the lattice frame, as in this embodiment. In addition, when the length of the side is 1 to 2 m and the length L of the inspection frame K is 30 cm, it is sufficient to provide one inspection frame K for each side. Further, when the length of the side becomes larger, two or more inspection frames K having the above dimensions may be provided, but the length L of the inspection frame K is made larger (for example, 1.3 to 1. 5 m) may be set. Further, the inspection frame K may be provided over the entire length of the side.
【００１５】 以上のように構成した格子状鉄筋８に、例えば含水率が７〜８％程度の低スラ ンプのモルタルなど１１をモルタルガン機などの土木用吹付機（図示してない） によって吹き付ける。この場合、鉄筋８によって形成される格子枠の各辺には、 モルタルなど１１の吹き付け幅および吹き付け高さの目安となる検測枠Ｋを設け てあるので、この検測枠Ｋにしたがってモルタルなど１１の吹き付けを行うだけ で、所定寸法のモルタル等よりなる格子状法枠（以下、単に格子状法枠という） １２を容易に形成することができる。すなわち、この実施例においては、下端幅 ３０〜３５ｃｍ、高さ１０〜１５ｃｍ程度の格子状法枠１２を形成することがで き、所定寸法および所定強度の格子状法枠１２を確実に形成できるのである。な お、図１および図３において、符号１３はモルタルなど１１を吹き付けるための ノズルである。On the grid-shaped reinforcing bar 8 configured as described above, for example, 11 such as a low-slump mortar having a water content of about 7 to 8% is sprayed with a spraying machine for civil engineering (not shown) such as a mortar gun machine. . In this case, since each side of the lattice frame formed by the reinforcing bars 8 is provided with an inspection frame K that serves as a guide for the spraying width and the spraying height of the mortar 11 and the like, the mortar etc. A lattice-shaped method frame (hereinafter, simply referred to as a lattice-shaped method frame) 12 made of mortar or the like having a predetermined size can be easily formed by only spraying 11. That is, in this embodiment, the lattice-shaped method frame 12 having a lower end width of 30 to 35 cm and a height of 10 to 15 cm can be formed, and the lattice-shaped method frame 12 having a predetermined size and a predetermined strength can be reliably formed. Of. In FIGS. 1 and 3, reference numeral 13 is a nozzle for spraying 11 such as mortar.
【００１６】 以上のようにして法面５に形成された格子状法枠１２内に、土壌、有機質材、 保水材（土壌改良材）などと芝草、野草、花、低木類などの種子とを混合してな る植生材料を動力吹付け機などを用いて吹き付けて植生層１４（図１参照）を形 成したり、また、これに代えて、前記植生材料を粗目の袋体に充填した植生袋（ 図示してない）を配置するなどして、従来不可能とされていた岩盤法面などにも 植生を導入することが可能となり、法面の景観の向上および植生の根や茎などに よる法面の恒久的安定に寄与するところが大きい。Soil, organic material, water retention material (soil conditioner), etc. and seeds of turfgrass, wild grass, flowers, shrubs, etc. are placed in the lattice-shaped method frame 12 formed on the slope 5 as described above. The mixed vegetation material was sprayed using a power sprayer or the like to form the vegetation layer 14 (see FIG. 1), or alternatively, the vegetation material was filled in a coarse bag. By arranging a vegetation bag (not shown), it becomes possible to introduce vegetation even on rock slopes, which were previously impossible, to improve the landscape of slopes and to improve roots and stems of vegetation. It greatly contributes to the permanent stability of the slope due to.
【００１７】 この考案は、上述の実施例に限られるものではなく、種々に変形して実施でき る。以下、変形例を図に基ずいて説明する。なお、以下の図において、図１〜図 ４までの符号と同一のものは同一物である。The present invention is not limited to the above-described embodiment, but can be modified in various ways. Hereinafter, modified examples will be described with reference to the drawings. In the following figures, the same parts as those in FIGS. 1 to 4 are the same.
【００１８】 まず、図５は、鉄筋８と網状体６とを鉄筋保持部材３によって浮設保持した状 態でモルタルなど１１を吹き付けた例を示している。すなわち、鉄筋８を鉄筋保 持部材３によって保持した後、網状体６を持ち上げ、適宜の結束線１５を用いて 網状体６を鉄筋８あるいは鉄筋保持部材３に結束し、その状態でモルタルなど１ １を吹き付けるのである。First, FIG. 5 shows an example in which mortar 11 or the like is sprayed in a state in which the reinforcing bar 8 and the net-like body 6 are suspended and held by the reinforcing bar holding member 3. That is, after holding the reinforcing bar 8 by the reinforcing bar holding member 3, the reticulated body 6 is lifted up, and the reticulated body 6 is bound to the reinforcing bar 8 or the rebar holding member 3 by using an appropriate binding wire 15. Spray one.
【００１９】 図６は、鉄筋８のみを浮設保持した実施態様を示している。このようにした場 合、格子状法枠１２での植生層１４の厚みが５ｃｍ未満の場合、網状体６が吹き 付け基材としての植生材料の流亡防止材として有効に作用する。この場合、適宜 のスぺーサ１６を用いて、網状体６を浮設保持してもよい。なお、前記スぺーサ １６としては、例えば本願出願人に係る昭和６３年意匠登録第４４１８号の「法 面の保護用ラススぺーサー」や、本願出願人に係る実公平５ー４２１１８号公報 の「スぺーサーピン」を用いることができる。FIG. 6 shows an embodiment in which only the reinforcing bar 8 is suspended and held. In this case, when the thickness of the vegetation layer 14 in the lattice-shaped method frame 12 is less than 5 cm, the reticulate body 6 effectively acts as a runoff prevention material for the vegetation material as the spray base material. In this case, the mesh body 6 may be floated and held by using an appropriate spacer 16. The spacer 16 may be, for example, “Last Spacer for Slope Protection” of Design Registration No. 4418 of the applicant of the present application, or Japanese Utility Model Publication No. 5-42118 of the applicant of the present application. A "spacer pin" can be used.
【００２０】 次に、検測枠Ｋの変形例を説明する。図７に示すように、検測枠Ｋにおいて、 二つの第１部材１が、二つの長辺１７Ａと二つの短辺１７Ｂとからなる矩形体１ ７によって連結するようにしてもよい。この矩形体１７は、例えば防錆加工を施 した適宜太さの針金からなり、その二つの短辺１７Ｂに二つの第１部材１が例え ば溶接によってそれぞれ固着されている。すなわち、この検測枠Ｋにおいては、 二つの長辺１７Ａが図４に示した検測枠Ｋにおける第２部材２に相当し、二つの 短辺１７Ｂが鉄筋保持部材３として機能する。つまり、この例は、検測枠Ｋにお ける第２部材２と鉄筋保持部材３とを一体化したものである。このような検測枠 Ｋは、その製作がより簡単となる。なお、前記矩形体１７は正方形であってもよ い。Next, a modified example of the inspection frame K will be described. As shown in FIG. 7, in the inspection frame K, the two first members 1 may be connected by a rectangular body 17 having two long sides 17A and two short sides 17B. The rectangular body 17 is made of, for example, a wire of an appropriate thickness that has been subjected to rust prevention processing, and the two first members 1 are fixed to the two short sides 17B of each by welding, for example. That is, in this inspection frame K, the two long sides 17A correspond to the second member 2 in the inspection frame K shown in FIG. 4, and the two short sides 17B function as the reinforcing bar holding member 3. That is, in this example, the second member 2 and the reinforcing bar holding member 3 in the inspection frame K are integrated. Such an inspection frame K becomes easier to manufacture. The rectangular body 17 may be square.
【００２１】 上述の実施例は、いずれも鉄筋保持部材３，１７Ｂを固定的に設けたものであ ったが、図８に示すように構成してもよい。すなわち、この図において、１８は 鉄筋保持部材で、例えば防錆加工を施した適宜太さの針金からなる。この鉄筋保 持部材１８の一端側には、ループ部１８Ａが形成され、このループ部１８Ａが第 １部材１の例えば一方の脚部１Ｂにおける第１部材１と第２部材２との一方の連 結点の直ぐ上位の箇所に、図中矢印で示す方向に回動できるように、遊動状態に 係着されている。そして、鉄筋保持部材１８の他端側には、フック部１８Ｂが形 成され、第２部材２とほぼ平行な状態である第１状態から第２部材２と直交する 第２状態（鉄筋保持部材１８が一対の脚部１Ｂを結ぶ方向、図中、実線で示す） にしたとき、フック部１８Ｂを連結部材２に引っ掛けることにより第２状態を保 持できるように構成され、常時は第１状態にある。In all of the above-described embodiments, the reinforcing bar holding members 3 and 17B are fixedly provided, but they may be configured as shown in FIG. That is, in this figure, reference numeral 18 denotes a reinforcing bar holding member, which is made of, for example, a wire of an appropriate thickness that has been subjected to rust prevention processing. A loop portion 18A is formed on one end side of the reinforcing bar holding member 18, and the loop portion 18A connects one of the first member 1 and the second member 2 in the leg portion 1B of the first member 1, for example. It is attached to a position immediately above the junction in a floating state so that it can rotate in the direction indicated by the arrow in the figure. A hook portion 18B is formed on the other end side of the reinforcing bar holding member 18, and the hook member 18B is formed substantially parallel to the second member 2 from a first state to a second state (reinforcing bar holding member) orthogonal to the second member 2. 18 is a direction connecting the pair of leg portions 1B, which is indicated by a solid line in the drawing), the hook portion 18B is hooked on the connecting member 2 so that the second state can be maintained, and the first state is normally set. It is in.
【００２２】 このように構成された検測枠Ｋは、常時は、鉄筋保持部材１８が第２部材２と ほぼ平行である第２状態にあるので、保管や運搬などにおいて、検測枠Ｋをコン パクトに重ね合わせることができる。In the inspection frame K configured as described above, the reinforcing bar holding member 18 is normally in the second state in which the reinforcing bar holding member 18 is substantially parallel to the second member 2. Therefore, the inspection frame K is stored and transported. Can be stacked compactly.
【００２３】 なお、図８に示した検測枠Ｋにおいては、鉄筋保持部材１８のループ部１８Ａ を第１部材１の一方の脚部１Ｂに設けていたが、第２部材２に設けるようにして もよい。また、鉄筋保持部材１８のフック部１８Ｂを第１部材１の他の脚部１Ｂ に引っ掛けるようにしてもよい。In the inspection frame K shown in FIG. 8, the loop portion 18A of the reinforcing bar holding member 18 is provided on the one leg portion 1B of the first member 1, but it may be provided on the second member 2. May be. Further, the hook portion 18B of the reinforcing bar holding member 18 may be hooked on the other leg portion 1B of the first member 1.
【００２４】 上述した実施例においては、鉄筋保持部材３，１７Ｂ，１８は、それらの両端 または一方が検測枠Ｋの主たる構成部材である第１部材１または第２部材２に固 着または係着されていたが、これを着脱自在に設けるようにしてもよい。図９は このように構成した例を示すもので、この図において、１９は例えば防錆加工を 施した適宜太さおよび適宜長さの針金で、対向する第２部材２間に掛けわたされ 、両端部において適宜の結束線２０を用いて第２部材２に結束固定されて、鉄筋 保持部材１９に形成されている。In the above-described embodiment, the reinforcing bar holding members 3, 17 B, 18 are fixed or attached to the first member 1 or the second member 2, which is the main constituent member of the inspection frame K, at one or both ends thereof. Although it was worn, it may be detachably provided. FIG. 9 shows an example of such a configuration. In this figure, 19 is, for example, a wire with an appropriate thickness and an appropriate length that has been subjected to rust prevention processing, and is hung between the opposing second members 2. Both ends are bound and fixed to the second member 2 by using appropriate binding wires 20, and are formed on the reinforcing bar holding member 19.
【００２５】 このように構成した検測枠Ｋにおいては、その本体が、常時は第１部材１と第 ２部材２とからなるので、コンパクトとなり、保管や運搬などにおいて好都合で ある。また、この実施例において、鉄筋保持部材１９の第２部材２への結束は、 検測枠Ｋを鉄筋８に対してセットする際行う方法と、予め行っておく方法とがあ るが、セットの際結束を行う方が、鉄筋８の保持を行うための作業をより行いや すい。In the inspection frame K configured as described above, the main body is always composed of the first member 1 and the second member 2, so that it is compact and convenient for storage and transportation. In this embodiment, the binding of the reinforcing bar holding member 19 to the second member 2 may be performed when setting the inspection frame K on the reinforcing bar 8 or may be performed in advance. It is easier to carry out the work for holding the reinforcing bars 8 by binding them.
【００２６】 図９に示した実施例においては、鉄筋保持部材１９を結束線２０によって固定 していたが、これに代えて、図１０に示すようにしてもよい。すなわち、この図 に示す例では、例えば防錆加工を施した適宜太さおよび適宜長さの針金２１に両 端部を例えば同じ方向に折曲してフック部２１Ａを形成し、このフック部２１Ａ を第２部材２に係合させるようにして鉄筋保持部材２１としている。なお、この 実施例において、フック部２１Ａを第１部材１の脚部１Ｂにおける第２部材２と の連結部分より上方において係合させるようにしてもよい。In the embodiment shown in FIG. 9, the reinforcing bar holding member 19 is fixed by the binding wire 20, but instead of this, it may be made as shown in FIG. That is, in the example shown in this figure, both ends are bent in the same direction, for example, to form a hook portion 21A on a wire 21 having an appropriate thickness and an appropriate length that has been subjected to rust prevention processing. Are engaged with the second member 2 to form the reinforcing bar holding member 21. In this embodiment, the hook portion 21A may be engaged above the connecting portion of the leg portion 1B of the first member 1 with the second member 2.
【００２７】 図１０に示したように構成した検測枠Ｋにおいては、図９に示した検測枠Ｋと 同様の効果があるとともに、さらに、鉄筋保持部材２１の取り付けにおいて結束 線を必要としないほか、その取り付けを容易に行なえるといった利点がある。The inspection frame K configured as shown in FIG. 10 has the same effect as the inspection frame K shown in FIG. 9, and further requires a binding wire for attaching the reinforcing bar holding member 21. Besides, there is an advantage that it can be easily attached.
【００２８】 図１１は、図１０に示した実施例に変形例を示すもので、この実施例において は、鉄筋保持部材２１の長さ方向の中間部において鉄筋保持部材２１をやや折曲 し、鉄筋８を安定に保持するための安定保持部２２を形成している。図示する例 では、鉄筋保持部材２１のほぼ中央部を下方に屈曲し、この部分２２に鉄筋８（ 図示してない）を安定に保持できるようにしている。そして、この実施例におい ては、第２部材２を第１部材１の脚部１Ｂのかなり上方において固着している。 これは、所定の被り厚が得られるように鉄筋８を保持するためである。FIG. 11 shows a modification of the embodiment shown in FIG. 10. In this embodiment, the reinforcing bar holding member 21 is slightly bent at an intermediate portion in the longitudinal direction of the reinforcing bar holding member 21, A stable holding portion 22 for stably holding the reinforcing bar 8 is formed. In the illustrated example, the reinforcing bar holding member 21 is bent at a substantially central portion thereof so that the reinforcing bar 8 (not shown) can be stably held in this portion 22. Then, in this embodiment, the second member 2 is fixed to a position considerably above the leg portion 1B of the first member 1. This is for holding the reinforcing bar 8 so that a predetermined covering thickness can be obtained.
【００２９】 なお、前記安定保持部２２は、鉄筋保持部材２１に上方に開いた凹部を形成す るなどにより形成してもよく、この場合、鉄筋保持部材２１を必ずしも屈曲させ る必要はない。また、図４，図７〜図９にそれぞれ示した鉄筋保持部材３，１７ Ｂ，１８，１９においても、図１１に示した鉄筋保持部材２１と同様の安定保持 部２２を形成しあってもよい。The stable holding portion 22 may be formed by forming a concave portion that opens upward in the reinforcing bar holding member 21. In this case, the reinforcing bar holding member 21 does not necessarily have to be bent. Further, also in the reinforcing bar holding members 3, 17 B, 18, 19 shown in FIGS. 4, 7 to 9, respectively, even if the stable holding portion 22 similar to the reinforcing bar holding member 21 shown in FIG. 11 is formed. Good.
【００３０】 上記実施例においてはいずれも、検測枠Ｋにおける第１部材１の正面視形状が 台形であったが、この考案はこれに限られるものではなく、図１２に示すように 三角形（図示する例では二等辺三角形）に形成してもよい。この図において、符 合２３は第１部材、２４は第１部材２３の脚部（等辺）間に横設される鉄筋保持 部材である。このように構成した検測枠Ｋにおいても、上記各実施例と同様の効 果があり、また、これを用いた法枠工法においても同様の効果を奏する。さらに 、第１部材２３が力学的に安定な三角形であるので、検測枠Ｋとしてより安定度 が大きい。In each of the above embodiments, the front view shape of the first member 1 in the inspection frame K is trapezoidal, but the present invention is not limited to this, and as shown in FIG. It may be formed in an isosceles triangle in the illustrated example. In this figure, reference numeral 23 is a first member, and reference numeral 24 is a reinforcing bar holding member provided laterally between leg portions (equal sides) of the first member 23. The inspection frame K configured as described above also has the same effects as those of the above-described respective examples, and the same effect can be obtained in the method of frame construction using the same. Furthermore, since the first member 23 is a mechanically stable triangle, the stability of the inspection frame K is higher.
【００３１】 図１３は、第１部材の正面視形状を左右対称形の五角形に形成したもので、こ の図において、符号２５は第１部材、２６は第１部材２５の脚部２５Ｂ間の横設 される鉄筋保持部材である。このように構成した検測枠Ｋにおいても、上記各実 施例と同様の効果があり、また、これを用いた法枠工法においても同様の効果を 奏する。そして、この実施例の検測枠Ｋによれば、頂点２５ａを目安にしてモル タルなど１１を吹き付けるだけで、所定の被り厚を有する格子状法枠１２を形成 することができる。なお、図示しないが、第１部材２５を左右対称形または非対 称形の五角形以上に多角形状としてもよい。In FIG. 13, the front view shape of the first member is formed into a left-right symmetrical pentagonal shape. In this figure, reference numeral 25 is a first member, and 26 is a space between legs 25 B of the first member 25. It is a reinforcing bar holding member installed horizontally. The inspection frame K configured as described above also has the same effects as those of the above-described respective embodiments, and also the same effect can be obtained in the legal frame construction method using the same. Then, according to the inspection frame K of this embodiment, the lattice-shaped method frame 12 having a predetermined covering thickness can be formed only by spraying 11 such as mortar with the apex 25a as a guide. Although not shown, the first member 25 may have a polygonal shape having a bilaterally symmetrical or asymmetrical pentagon.
【００３２】 図１４は、第１部材に正面視形状を左右対称形の凹多角形としたもので、より 詳しくは、第１部材２７として、上部に一つの凸部２７ａと二つの凹部２７ｂを 有する凹多角形（左右対称形が好ましい）に形成されている。２８は第１部材２ ７の脚部２７Ｂ間を連結するように横設される鉄筋保持部材である。このように 構成された検測枠Ｋにおいても、上記各実施例と同様の効果があり、また、これ を用いた法枠工法においても同様の効果を奏する。そして、この実施例の検測枠 Ｋにおいては、図示するように、二つの凹部２７ｂに２本の鉄筋８を安定に保持 でき、鉄筋保持部材２８にも２本の鉄筋８を保持でき、所謂４本配筋構造の格子 状法枠など背の高い格子状法枠を形成するのに好都合である。なお、鉄筋保持部 材２８に１本の鉄筋８を配置してもよいことは言うまでもない。In FIG. 14, the first member is a left-right symmetrical polygonal concave polygon, and more specifically, as the first member 27, one convex portion 27a and two concave portions 27b are provided on the upper portion. It has a concave polygonal shape (preferably a left-right symmetrical shape). Reference numeral 28 is a reinforcing bar holding member that is provided so as to connect between the leg portions 27B of the first member 27. The inspection frame K configured in this way also has the same effects as those of the above-described respective embodiments, and the same method effect can be obtained in the legal frame construction method using the same. In the inspection frame K of this embodiment, as shown in the drawing, the two reinforcing bars 8 can be stably held in the two recesses 27b, and the two reinforcing bars 8 can also be held in the reinforcing bar holding member 28. It is convenient to form a tall grid-shaped frame such as a grid-shaped frame with four reinforcing bars. It goes without saying that one reinforcing bar 8 may be arranged on the reinforcing bar holding member 28.
【００３３】 また、この実施例の検測枠Ｋを用いた場合、第１部材２７の上部のほぼ中央２ ７ａが上方に突出し、さらに、この凸部２７ａの両側に形成される二つの凹部２ ７ｂの他方にも凸部２７ｃが形成されているので、モルタルなど１１の吹き付け 時には、これらの凸部２７ａ，２７ｃを目安にして吹き付ければ、所定の被り厚 の格子状法枠１２を形成することができ、後述するような検測ピン３３（図１６ および図１８参照）を用いなくてもよい。Further, when the inspection frame K of this embodiment is used, substantially the center 27a of the upper portion of the first member 27 projects upward, and further, the two concave portions 2 formed on both sides of the convex portion 27a. Since the convex portion 27c is also formed on the other side of 7b, when the mortar 11 is sprayed, if these convex portions 27a and 27c are sprayed as a guide, the lattice-shaped frame 12 having a predetermined covering thickness is formed. However, it is not necessary to use the inspection pin 33 (see FIGS. 16 and 18) as described later.
【００３４】 図１５は、この検測枠Ｋに用いる鉄筋保持部材２８の変形例を示している。こ の図において図１４に示すものと同じ符合が付された部材は同一または同等の部 材であるので、その詳細な説明を省略する。この鉄筋保持部材２８は、２つの鉄 筋保持部２８Ｃを設けるよう、凹部が２つ設けられている。このように構成する と、鉄筋の保持部が正確に決まるとともに、鉄筋の保持がより安定にできる効果 を有する。なお、図１５においては、沈み防止部４を他の実施例は互いに向き合 う方向に曲折して形成していたのを、外側に曲折した実施例を示しており、他の 実施例における検測枠においても同様に形成してよいことは言うまでもない。FIG. 15 shows a modification of the reinforcing bar holding member 28 used for the inspection frame K. In this figure, the members denoted by the same reference numerals as those shown in FIG. 14 are the same or equivalent members, and thus detailed description thereof will be omitted. The reinforcing bar holding member 28 is provided with two recesses so as to provide two reinforcing bar holding portions 28C. With this structure, the holding portion of the reinforcing bar is accurately determined, and the holding of the reinforcing bar can be made more stable. In addition, in FIG. 15, the sink preventing portion 4 is formed by bending in a direction facing each other in the other embodiments, but an example is shown in which the sink preventing portion 4 is bent outward. It goes without saying that the measurement frame may be formed in the same manner.
【００３５】 図１６は、第１部材の正面視形状をＭ字状（左右対称形が好ましい）に形成し たもので、この図において、符号２９は第１部材、３０は第１部材２９の脚部２ ９Ｂ間を連結するように横設される鉄筋保持部材である。このように構成された 検測枠Ｋにおいても、上記各実施例と同様の効果があり、また、これを用いた法 枠工法においても同様の効果を奏する。FIG. 16 shows the front view of the first member formed in an M-shape (a symmetrical shape is preferable). In this figure, reference numeral 29 is the first member and 30 is the first member 29. It is a reinforcing bar holding member which is installed laterally so as to connect between the leg portions 29B. The inspection frame K configured in this way also has the same effects as those of the above-described respective examples, and the same method and frame frame construction method also has the same effects.
【００３６】 さらに、この実施例の検測枠Ｋを用いた場合、第１部材２９の上部のほぼ中央 が下方に凹んでいるので、この凹み部分２９ａの高さ位置を所定の被り厚が得ら れるように設置すれば、この部分２９ａによって鉄筋８を、鉄筋保持部材３０に よって保持される鉄筋８とは別に、安定した状態で保持させることができる。つ まり、この構造の検測枠Ｋは、格子状法枠１２の寸法を規制する機能のほかに、 鉄筋８を上下方向に２段に保持する機能も有するので、より高い格子状法枠１２ を形成するような場合、好都合であるといった利点がある。なお、この図におい て、符号３３はモルタルなど１１の吹付け厚を規定するため、法面５に立設され る検測ピンである。Further, in the case of using the inspection frame K of this embodiment, the upper portion of the first member 29 has a substantially center recessed downward, so that the height position of the recessed portion 29a is set to a predetermined covering thickness. If installed so as to be released, the rebar 8 can be held in a stable state by the portion 29a separately from the rebar 8 held by the rebar holding member 30. In other words, the inspection frame K of this structure has not only the function of restricting the size of the lattice-shaped frame 12 but also the function of holding the reinforcing bars 8 in two stages in the vertical direction. In the case of forming, there is an advantage that it is convenient. In this figure, reference numeral 33 is an inspection pin which is erected on the slope 5 in order to define the spraying thickness of the mortar 11 or the like.
【００３７】 その他の実施例として、検測枠Ｋにおける第１部材１の正面視形状を、例えば 図１７に示すように弓状に形成してもよい。この図において、符合３１は第１部 材、３２は第１部材３１の脚部（等辺）間に横設される鉄筋保持部材である。こ のように構成した検測枠Ｋにおいても、上記各実施例と同様の効果があり、また 、これを用いた法枠工法においても同様の効果を奏する。さらに、第１部材３１ が形成しようとする格子状法枠の形状そのものであるため、この検測枠Ｋの形状 に併せてモルタルなど１１を吹き付けるだけで、規定通りで所定の被り厚を有す る格子状法枠１２を形成することができる。As another example, the front view shape of the first member 1 in the inspection frame K may be formed in an arc shape as shown in FIG. 17, for example. In this figure, reference numeral 31 is a first member, and 32 is a reinforcing bar holding member provided laterally between leg portions (equal sides) of the first member 31. The inspection frame K configured as described above also has the same effect as that of each of the above-described embodiments, and the method of frame construction using this also has the same effect. Further, since the first member 31 is the shape of the grid-shaped method frame itself to be formed, only by spraying mortar 11 together with the shape of the inspection frame K, a predetermined covering thickness can be obtained. The grid-shaped method frame 12 can be formed.
【００３８】 図１８は、鉄筋８を上下２段に設ける他の実施態様を示すもので、この例にお いては、図４に示したような正面視形状が台形の第１部材１を有する検測枠Ｋを 用い、第１部材１の水平な上辺１Ａによっても鉄筋８を保持させるようにして、 上下２段に鉄筋８を保持させるようにしている。この場合も検測ピン３３を用い て、モルタルなど１１の吹付け厚を規定している。FIG. 18 shows another embodiment in which the reinforcing bars 8 are provided in upper and lower two stages. In this example, the first member 1 having a trapezoidal shape in a front view as shown in FIG. 4 is provided. The inspection frame K is used to hold the reinforcing bar 8 by the horizontal upper side 1A of the first member 1 so that the reinforcing bar 8 is held in two upper and lower stages. In this case as well, the spraying thickness of the mortar 11 or the like is specified using the inspection pin 33.
【００３９】 また、実施例として示したいずれの検測枠Ｋにおいても、鉄筋保持部材に、図 １１に示した鉄筋保持部材２１と同様に、安定保持部２２を形成してもよいこと は言うまでもない。Further, in any of the inspection frames K shown as examples, it goes without saying that a stable holding portion 22 may be formed on the reinforcing bar holding member, similar to the reinforcing bar holding member 21 shown in FIG. Yes.
【００４０】 また、前記いずれの実施例においても、検測枠Ｋにおける第１部材の下端部を 折曲して沈み防止部４を形成してあったが、前記下端部を折曲しないでストレー トな状態にしてあってもよいことは言うまでもない。Further, in any of the above-described embodiments, the lower end of the first member of the inspection frame K is bent to form the sunken portion 4, but the stray is not bent at the bottom. It goes without saying that it may be in good condition.
【００４１】 さらに、前記いずれの実施例においても、検測枠Ｋにおける第２部材２の設置 高さは任意であるが、鉄筋８の被り厚を所定値以上確保したい場合は、第１部材 の高い位置に固定するのが望ましい。また、第１部材は３以上設けてあってもよ し、検測枠Ｋをプラスチックによって一体成形によって形成してあってもよい。Further, in any of the above-mentioned embodiments, the installation height of the second member 2 in the inspection frame K is arbitrary, but when it is desired to secure the covering thickness of the reinforcing bar 8 at a predetermined value or more, It is desirable to fix it in a high position. Further, three or more first members may be provided, and the inspection frame K may be integrally formed of plastic.
【００４２】 さらにそして、鉄筋保持部材によって２あるいはこれ以上の複数の鉄筋８を適 宜の間隔をおいて保持させるようにしてもよく、その場合、これらの鉄筋保持部 材に、図１１に示すような安定保持部２２を形成してもよいことは言うまでもな い。また、格子枠の一つの辺に設けられる鉄筋８は必ずしも１本でなくても複数 本でもよく、その場合、鉄筋８の交点付近に４本の長目のアンカーを法面５に打 ち込み、鉄筋を井桁状に支承結束し、これを一段あるいは数段重ねるようにして もよい。Further, two or more reinforcing bars 8 may be held at appropriate intervals by a reinforcing bar holding member. In that case, these reinforcing bar holding members are shown in FIG. It goes without saying that such a stable holding portion 22 may be formed. Further, the number of the reinforcing bars 8 provided on one side of the lattice frame is not necessarily one and may be plural. In that case, four long anchors are driven on the slope 5 near the intersection of the reinforcing bars 8. , Reinforcing bars may be bound and supported in the shape of double girders, and they may be stacked in one or several steps.
【００４３】 さらにまた、いずれの実施例においても、鉄筋保持部材は第１部材あるいは第 ２部材に、溶接またはハンダ付けさらには番線等による結束手段により固着して もよいし、図７に示した矩形体による連結手段により鉄筋保持部材を構成しても よい。さらに、鉄筋保持部材の一端側にループ部を形成し、他端側にはフック部 を形成して、鉄筋保持部材が遊動自在にして第１部材あるいは第２部材に係止で きるようにしてもよいし、鉄筋保持部材の両端にフック部を形成して、第１部材 あるいは第２部材に係止できるようにしてもよい。Furthermore, in any of the embodiments, the reinforcing bar holding member may be fixed to the first member or the second member by welding or soldering, or by a binding means such as a numbering wire, as shown in FIG. The reinforcing bar holding member may be configured by a connecting means having a rectangular shape. Further, a loop portion is formed on one end side of the reinforcing bar holding member, and a hook portion is formed on the other end side thereof so that the reinforcing bar holding member can freely move and can be locked to the first member or the second member. Alternatively, hook portions may be formed at both ends of the reinforcing bar holding member so that the reinforcing member holding member can be engaged with the first member or the second member.
