Description
この発明は、例えば法枠の簡易な形成に資する検測枠並びにこれを用いた法面保護工法及び構造体に関する。 The present invention relates to a measurement frame that contributes to, for example, simple formation of a method frame, and a slope protection method and structure using the same.
鉄筋にモルタルまたはコンクリートを吹き付けて断面略半円状の法枠を形成する簡易吹付け法枠工法に用いられ、モルタル等の吹付け時に鉄筋を保持する機能（保持機能）と法枠の形状寸法の目安となる機能（目安機能）とを発揮する検測枠として、特許文献１には、複数の線材によって構成された検測枠が記載されている。 Used in a simple spray method frame method that forms a semi-circular cross section by spraying mortar or concrete on the reinforcing bar. Function to hold the rebar when spraying mortar (holding function) and shape dimensions of the frame As a measurement frame that exhibits a standard function (standard function), Patent Document 1 describes a measurement frame constituted by a plurality of wires.
しかし、検測枠を構成する線材の本数が増えるほど、材料の節約を図れないばかりか、それらの線材を溶接等で連結する工程も多く必要となり、コストダウンや生産の効率化を殆ど見込めない。 However, as the number of wires that make up the inspection frame increases, not only can the material be saved, but more steps are required to connect these wires by welding, etc., and cost reduction and production efficiency can hardly be expected. .
本発明は上述の事柄に留意してなされたもので、その目的は、用いる線材の本数を減らして溶接等の連結に必要な工数の削減を図り、材料の節約による省資源や施工性の向上に寄与し得る検測枠並びにこれを用いた法面保護工法及び構造体を提供することにある。 The present invention has been made in consideration of the above-mentioned matters, and its purpose is to reduce the number of wires used to reduce the number of man-hours required for connection such as welding, and to improve resource saving and workability by saving materials. It is an object of the present invention to provide a measurement frame that can contribute to the above, a slope protection method using the same, and a structure.
上記目的を達成するために、本発明に係る検測枠は、芯材を内包し芯材が延びる方向に対し直交する方向の縦断面の上縁が上に凸のアーチをなす膨出体を法面上に形成する際に芯材を保持し、かつ形成後の膨出体に芯材と共に内包される検測枠であって、実質的に一本の線材を複数箇所で曲げてなる形状を呈し、線材両端側から線材中央側に向けて、前記上縁の目安となるように***した形状の目安部と、芯材を浮設保持するために前記目安部より低く***した形状の***部とを有し、線材中央よりも線材一端側の部位と線材他端側の部位とが互いに鏡像の関係となっていることを特徴としている（請求項１）。
ここで、「実質的に一本の線材を複数箇所で曲げてなる形状を呈する」とは、複数箇所で曲がった一本の線材のみによって検測枠が構成される場合と、検測枠が複数の線材によって検測枠が構成され、かつ、検測枠の一端から他端までの基幹ルート（最短ルート）が、複数箇所で曲がった一本の線材からなるとみなすことができる場合（検測枠の一端から他端までの間に存在する線材どうしの接合箇所が一つのみであるか、または複数であってもそれらが直列関係にあり、並列関係にはない場合）との両方を含むものである。
In order to achieve the above object, a measurement frame according to the present invention includes a bulging body that includes a core material and has an upwardly projecting arch whose upper edge in a direction perpendicular to the direction in which the core material extends extends upward. A measurement frame that holds the core material when forming on the slope and is enclosed with the core material in the bulged body after formation, and is formed by bending a single wire material at multiple locations. The guide part of the shape which protruded from the both ends of the wire to the center of the wire to become the reference of the upper edge, and the protrusion of the shape which protruded lower than the reference part to float and hold the core material possess a part, it is characterized in that the portions as wire end side than the wire center wire end side is a mirror image of each other (claim 1).
Here, “substantially presenting a shape formed by bending a single wire at multiple locations” means that the measurement frame is composed of only one wire bent at multiple locations, When the inspection frame is composed of multiple wires, and the basic route (shortest route) from one end to the other end of the inspection frame can be regarded as consisting of a single wire bent at multiple locations (inspection) Including the case where there is only one joint between the wire rods from one end to the other end of the frame, or even if there are multiple joints, they are in a serial relationship and not in a parallel relationship) It is a waste.
上記検測枠において、前記目安部の中間部分に、前記***部が保持する芯材とは別の芯材を浮設保持するために前記***部よりは高い位置にあるように沈降した形状の沈降部が設けられていてもよい（請求項２）。 In the inspection frame, in a middle portion of the reference portion, a shape that sinks so as to be higher than the raised portion in order to float and hold a core material different from the core material held by the raised portion. A settling part may be provided (claim 2).
上記検測枠において、二つの前記目安部は、互いに平行かつ鉛直方向に延びる平面上に位置し、各目安部と前記***部との間に存在する連絡部は、平面視において前記***部を二つの前記目安部の間に位置させるように各目安部側から前記***部側に向けて直線状に延びていてもよい（請求項３）。 In the inspection frame, the two reference portions are located on a plane extending in parallel and perpendicular to each other, and the communication portion existing between each reference portion and the raised portion is configured to connect the raised portion in plan view. You may extend linearly toward each said protruding part side from each reference | standard part side so that it may be located between two said reference | standard parts (Claim 3).
上記検測枠において、各前記目安部の線材末端側に、平面視において二つの目安部の左右端が計四つの頂点をなす四角形の中に納まるように略水平方向に延びる脚部が設けられていてもよい（請求項４）。 In the inspection frame, legs extending in a substantially horizontal direction are provided on the wire rod end side of each of the guide portions so that the left and right ends of the two guide portions fit in a quadrilateral having a total of four vertices in plan view. (Claim 4).
上記検測枠が、前記***部を複数有していてもよいし（請求項５）、前記***部を一つのみ有していてもよい（請求項６）。 The inspection frame may have a plurality of the raised portions (Claim 5), or may have only one raised portion (Claim 6).
上記目的を達成するために、本発明に係る法面保護構造は、法面上において芯材を保持した請求項１〜６の何れか一項に記載の検測枠の形状を目安にしながら該検測枠及び芯材を内包するように硬化材を盛って膨出体を形成する（請求項７）。 In order to achieve the above object, the slope protection structure according to the present invention is characterized in that the core is held on the slope while the shape of the measurement frame according to any one of claims 1 to 6 is used as a guide. A bulging body is formed by depositing a curing material so as to enclose the measurement frame and the core material (claim 7 ).
上記目的を達成するために、本発明に係る構造体は、請求項７に記載の法面保護工法によって法面上に形成されたものである（請求項８）。 To achieve the above object, the structure according to the present invention are those which are formed on the slope by the slope protection method of claim 7 (Claim 8).
本願発明では、用いる線材の本数を減らして溶接等の連結に必要な工数の削減を図り、材料の節約による省資源や施工性の向上に寄与し得る検測枠並びにこれを用いた法面保護工法及び構造体が得られる。 In the present invention, the number of wires used is reduced to reduce the number of man-hours required for connection such as welding, and a measurement frame that can contribute to resource saving and workability improvement by saving materials and slope protection using this A construction method and a structure are obtained.
すなわち、本願の各請求項に係る発明の検測枠は、実質的に一本の線材からなり、複数の線材どうしや一線材の異なる部位どうしを連結するための溶接等の連結工程が従来技術と比較して極端に少なくなるので、材料の節約による省資源、コストダウン及び生産の効率化を同時に図ることができる。例えば、特許文献１に記載の検測枠として、その形成に必要な線材長さが２４５ｃｍのものがあるが、寸法及び強度がこれと同等の検測枠を本願発明に則って作成する場合、必要な線材長さを１９５ｃｍとすることができ、約２０％の節約となる。 That is, the inspection frame of the invention according to each claim of the present application is substantially composed of a single wire, and a connecting process such as welding for connecting a plurality of wires or different parts of one wire is a conventional technique. Therefore, resource saving, cost reduction and production efficiency can be achieved simultaneously by saving materials. For example, the inspection frame described in Patent Document 1 has a wire length of 245 cm necessary for its formation, but when creating a measurement frame having dimensions and strength equivalent to this in accordance with the present invention, The required wire length can be 195 cm, saving about 20%.
請求項３に係る発明の検測枠は、芯材に直交させる二つの目安部の向きを、検測枠の向きを決めるときに参照することにより、検測枠の配置を極めて容易かつ正確に行うことができる。また、***部が目安部の直下から退避した位置にあるので、***部に芯材を保持させる作業を効率良く行うことができ、施工性の向上を図ることができる。さらに、連絡部は直線状に延びて最短となり、材料の節約を図れる。 The inspection frame of the invention according to claim 3 makes it very easy and accurate to arrange the measurement frames by referring to the directions of the two reference portions orthogonal to the core material when determining the orientation of the measurement frames. It can be carried out. In addition, since the raised portion is in a position retracted from directly below the reference portion, the work of holding the core material on the raised portion can be performed efficiently, and workability can be improved. Further, the connecting portion extends in a straight line and becomes the shortest, so that material can be saved.
請求項４に係る発明の検測枠では、法面が盛土等であっても水平方向に延びる脚部によってその沈み込みが防止され、しかもこの脚部は作業の邪魔にならない位置に納まるので、作業性を損なうこともない。 In the inspection frame of the invention according to claim 4, even if the slope is banking or the like, the sinking is prevented by the leg portion extending in the horizontal direction, and the leg portion is placed in a position that does not interfere with the work, Workability is not impaired.
請求項５に係る発明の検測枠では特に設置作業性の点で有利となり、請求項６に係る発明の検測枠では特に線材（材料）の節約面で有利となる。また、請求項１に係る発明の検測枠では、特に線材中央よりも線材一端側及び線材他端側に各々***部を設ける場合に、線材（材料）の節約面で有利となる。 The inspection frame of the invention according to claim 5 is particularly advantageous in terms of installation workability, and the inspection frame of the invention according to claim 6 is particularly advantageous in terms of saving wire (material). Further, the inspection frame of the invention according to claim 1 is advantageous in terms of saving the wire (material), particularly when the raised portions are provided on one end side and the other end side of the wire from the center of the wire.
図面を参照しながら以下に説明する。 This will be described below with reference to the drawings .
図１に示す本実施の形態に係る法面保護工法では、予め整備された法面Ｎに敷設された網状体１上において、芯材２に硬化材３を吹き付けて断面略半円状で平面視格子状の法枠（芯材２を内包し芯材２が延びる方向に対し直交する方向の縦断面の上縁が上に凸のアーチをなす膨出体の一例）４を形成する簡易吹付け法枠工法を実施した後、法枠４の各区画内に緑化工を施して植生層５を形成し、法枠４と植生層５とからなる構造体（法面補強構造体）を法面Ｎ上に構築する。 In the slope protection method according to the present embodiment shown in FIG. 1, a hardened material 3 is sprayed onto a core material 2 on a mesh body 1 laid on a slope N prepared in advance, and the plane is substantially semicircular in cross section. A simple blow that forms a lattice-like frame (an example of a bulging body that encloses the core material 2 and has an upwardly convex arch on the upper edge in a direction perpendicular to the direction in which the core material 2 extends) After performing the method frame construction method, greening is performed in each section of the method frame 4 to form a vegetation layer 5, and a structure (slope reinforcement structure) composed of the method frame 4 and the vegetation layer 5 is applied to the method. Build on surface N.
ここで、簡易吹付け法枠工法の実施に際し、網状体１としては例えば目合いが５〜６ｃｍ程度の菱形金網（ラス金網）を、その網状体１の敷設には例えば長さが２０〜４０ｃｍ程度のアンカーピン（図示していない）を、芯材２としては例えば断面略円形状で６〜１０ｍｍ程度の直径を有する鉄筋を、硬化材３としては例えば含水率が７〜８％の低スランプのモルタルやコンクリートを、その硬化材３の吹付けにはモルタルガン機などの土木用吹付機を、それぞれ用いることができる。 Here, when carrying out the simple spray frame method, for example, a rhombus wire mesh having a mesh size of about 5 to 6 cm is used as the mesh body 1, and a length of 20 to 40 cm is used for laying the mesh body 1. An anchor pin (not shown) of about, a core member 2 having a substantially circular cross section and a diameter of about 6 to 10 mm, and a hardening member 3 having a low slump with a moisture content of 7 to 8%, for example. A mortar or concrete can be used, and a spraying machine for civil engineering such as a mortar gun machine can be used for spraying the hardener 3.
また、法枠４の各区画内に施す緑化工として、本実施形態では植生基材の吹付けを行う。ここで、植生基材としては、例えば土壌、有機質材、保水材（土壌改良材）などと芝草、野草、低木類等の種子とを混合してなるものを用いることができ、その吹付けには例えば動力吹付け機を利用可能であり、その吹付けは、例えば法面Ｎから３〜５ｃｍ程度の厚みを有する植生基材の層（植生層５）を形成するように行えばよい。 Moreover, as a revegetation work to be performed in each section of the method frame 4, in this embodiment, a vegetation base material is sprayed. Here, as a vegetation base material, for example, a mixture of soil, organic material, water retention material (soil improvement material), etc. and seeds of turfgrass, wild grass, shrubs, etc. can be used for spraying. For example, a power sprayer can be used, and the spraying may be performed so as to form a layer of vegetation base material (vegetation layer 5) having a thickness of about 3 to 5 cm from the slope N, for example.
そして、本実施形態の法面保護工法では、その前半に行う簡易吹付け法枠工法において芯材２に硬化材３を吹付ける際に検測枠６を用いる。すなわち、芯材２に硬化材３を吹き付ける際、網状体１上に芯材２を二本一対かつ上下二段構えにして各区画の一辺が１〜２ｍ程度の格子状に配置するのであり、検測枠６はその配置が維持されるように芯材２を保持する機能と、硬化材３を吹付けにより盛って形成しようとする法枠４の形状寸法の目安となる機能とを発揮する。また、検測枠６は、形成後の法枠４に芯材２と共に内包される。斯かる検測枠６の構成について以下に説明する。 And in the slope protection method of this embodiment, the measurement frame 6 is used when spraying the hardening | curing material 3 to the core material 2 in the simple spraying method frame method performed in the first half. That is, when the curing material 3 is sprayed on the core material 2, the core material 2 is arranged on the mesh body 1 in a lattice form in which one side of each section is about 1 to 2 m with a pair of upper and lower two stages. The inspection frame 6 exhibits a function of holding the core material 2 so that the arrangement thereof is maintained, and a function serving as a guide for the shape and size of the normal frame 4 to be formed by spraying the curing material 3. . In addition, the inspection frame 6 is enclosed together with the core material 2 in the formed method frame 4. The configuration of such a measurement frame 6 will be described below.
検測枠６は、図３に示すように、一本の線材を複数箇所で曲げてなる形状を呈し、実際に、検測枠６は、例えば防錆加工を施した適宜太さ（例えば直径４ｍｍ〜５ｍｍ）の針金よりなる金属線材を、線材折曲げ装置（図示していない）を用いて端から順に折り曲げて得られるものである。 As shown in FIG. 3, the inspection frame 6 has a shape formed by bending a single wire at a plurality of locations. Actually, the inspection frame 6 has an appropriate thickness (for example, a diameter, for example) subjected to rust prevention processing. 4 mm to 5 mm) is obtained by bending a metal wire made of wire in order from the end using a wire bending device (not shown).
また、検測枠６は、図２及び図３に示すように、線材両端側から線材中央側に向けて、形成しようとする法枠４の上縁の目安となるように***した形状の目安部７と、芯材２を浮設保持するために目安部７より低く***した形状の***部８と、二つの***部８を結ぶように直線状に延びる中央ブリッジ部９とを順に有する。そして、この検測枠６において、中央ブリッジ部９よりも線材一端側の部位と線材他端側の部位と（例えば図３において中央ブリッジ部９よりも手前側の部位と奥側の部位と）は互いに鏡像の関係となっており、さらには、線材中央（中央ブリッジ部９の中央）よりも線材一端側の部位と線材他端側の部位とは互いに鏡像の関係（全体が面対称構造）となっている。 Further, as shown in FIGS. 2 and 3, the inspection frame 6 is a measure of a shape that is raised so as to be a measure of the upper edge of the normal frame 4 to be formed from both ends of the wire toward the center of the wire. A portion 7, a raised portion 8 having a shape raised below the reference portion 7 in order to float and hold the core material 2, and a central bridge portion 9 extending linearly so as to connect the two raised portions 8 are sequentially provided. In the measurement frame 6, a part on one end side of the wire from the central bridge portion 9 and a part on the other end side of the wire (for example, a part on the near side and a part on the back side of the central bridge part 9 in FIG. 3). Are mirror images of each other, and moreover, the portion on the one end side of the wire and the portion on the other end side of the wire from the center of the wire (the center of the central bridge portion 9) are mirror images of each other (the entire surface is symmetrical). It has become.
二つの***部８は、上下二段構えで配置される一対の芯材２のうちの下方の芯材２を保持するためのものである。ここで、各***部８に下方の芯材２を保持させるには、例えば、上方の芯材２及び検測枠６よりも先に網状体１上に下方の芯材２を配置した後、二つの***部８がその下方の芯材２を跨いだ状態となるようにして検測枠６を置き、その下方の芯材２を持ち上げて適宜の結束線（図示していない）で二つの***部８にそれぞれ結束すればよい。 The two raised portions 8 are for holding the lower core material 2 of the pair of core materials 2 arranged in a two-stage manner. Here, in order to hold the lower core material 2 in each raised portion 8, for example, after the lower core material 2 is arranged on the mesh body 1 before the upper core material 2 and the measurement frame 6, The measurement frame 6 is placed so that the two raised portions 8 straddle the core material 2 below, and the core material 2 below is lifted up, and two appropriate binding lines (not shown) are used. What is necessary is just to bind to the protruding part 8, respectively.
ここで、目安部７と***部８との間に存在する連絡部１０は、平面視において二つの***部８を二つの目安部７の間に位置させるように目安部７側から***部８側に向けて直線状に延びている。このように、二つの***部８は、目安部７の直下を避けた位置にあるので、***部８に下方の芯材２を結束する際、作業者は***部８を視認し易く、かつ、目安部７が作業の邪魔にもなり難いので、その結束作業を効率良く行える。そして、中央ブリッジ部９及び連絡部１０を、網状体１の上面に接するような低い位置に這うように延ばしてあることは、この効果にとってプラスとなる。 Here, the connecting portion 10 that exists between the reference portion 7 and the raised portion 8 has the raised portion 8 from the reference portion 7 side so that the two raised portions 8 are positioned between the two reference portions 7 in a plan view. It extends linearly toward the side. In this way, the two raised portions 8 are in a position that avoids the position directly below the guide portion 7, so that when the lower core material 2 is bound to the raised portion 8, the operator can easily see the raised portion 8, and Since the reference portion 7 does not easily interfere with the work, the bundling work can be performed efficiently. And it is a plus for this effect that the central bridge part 9 and the connection part 10 are extended so that it may reach in the low position which touches the upper surface of the mesh body 1.
また、上下二段構えで配置される一対の芯材２のうちの上方の芯材２を保持するために、各目安部７の中間部分（頂部分）には、***部８よりは高い位置にあるように沈降した形状の沈降部１１が設けられている（図２、図３参照）。ここで、各沈降部１１に上方の芯材２を保持させるには、例えば、上方の芯材２よりも先に網状体１上に検測枠６を配置した後、二つの沈降部１１に上方の芯材２を架け渡し、適宜の結束線（図示していない）で二つの沈降部１１と上方の芯材２とをそれぞれ結束すればよい。そして、沈降部１１（目安部７）の直下に***部８が存在せず、中央ブリッジ部９及び連絡部１０が低い位置にあることは、沈降部１１に上方の芯材２を結束する作業の効率性にも寄与することとなる。 Moreover, in order to hold | maintain the upper core material 2 of a pair of core materials 2 arrange | positioned by two steps of upper and lower positions, in the intermediate part (top part) of each standard | standard part 7, it is a position higher than the protruding part 8. The settling part 11 of the shape which settled is provided (refer FIG. 2, FIG. 3). Here, in order to hold the upper core material 2 in each settling portion 11, for example, after the measurement frame 6 is arranged on the mesh body 1 before the upper core material 2, the two settling portions 11 are moved to each other. The upper core member 2 may be bridged, and the two sinking portions 11 and the upper core member 2 may be bound by appropriate binding wires (not shown). The fact that the raised portion 8 does not exist directly below the settling portion 11 (the guide portion 7) and the central bridge portion 9 and the connecting portion 10 are in a low position means that the upper core material 2 is bound to the settling portion 11 This also contributes to the efficiency of the system.
さらに、線材一端側（例えば図３において手前側）の目安部７、線材一端側の***部８、線材他端側（例えば図３において奥側）の目安部７、線材他端側の***部８は、互いに平行かつ鉛直方向に延びる平面上に位置し、中央ブリッジ部９は、各目安部７、***部８がそれぞれ位置（形成）する平面と直交する方向に延びている。従って、下方の芯材２を跨ぐように検測枠６を配置する際、下方の芯材２が延びる方向に対して直交させる各目安部７及び各***部８と、下方の芯材２が延びる方向に平行に配置する中央ブリッジ部９との全ての向きが検測枠６の向きを決めるときに参照する対象（目安）となり得るので、検測枠６の配置が極めて容易となる。 Furthermore, a reference portion 7 on one end side of the wire (for example, the front side in FIG. 3), a raised portion 8 on the one end side of the wire, a reference portion 7 on the other end side (for example, the rear side in FIG. 3), and a raised portion on the other end side of the wire rod 8 are positioned on planes that are parallel to each other and extend in the vertical direction, and the central bridge portion 9 extends in a direction perpendicular to the plane on which each guide portion 7 and the raised portion 8 are positioned (formed). Therefore, when the measurement frame 6 is arranged so as to straddle the lower core material 2, the reference portions 7 and the raised portions 8 that are orthogonal to the direction in which the lower core material 2 extends and the lower core material 2 are provided. Since all orientations with the central bridge portion 9 arranged in parallel with the extending direction can be an object (reference) to be referred to when determining the orientation of the measurement frame 6, the arrangement of the measurement frame 6 becomes extremely easy.
また、法面Ｎが盛土であるような場合に、網状体１上に配置した検測枠６が法面Ｎに沈み込むのを防止するために、目安部７の線材末端側に形成される末端脚部１２を略水平方向に延ばしてあり、目安部７の線材中央側に形成され目安部７と連絡部１０とを中継する中継脚部１３を、下向きに凸の略円弧状を呈するようにしてある（図２、図３参照）。尚、末端脚部１２、中継脚部１３はいずれも、目安部７が位置する平面と同一の平面上（目安部７を通る鉛直面上）において互いに近接する方向に延びているのであり、かつ、網状体１の目合いを通り抜けて法面Ｎに接する。 Further, when the slope N is embankment, in order to prevent the measurement frame 6 arranged on the mesh body 1 from sinking into the slope N, it is formed on the wire rod end side of the reference portion 7. The end leg 12 is extended in a substantially horizontal direction, and the relay leg 13 that is formed on the wire rod center side of the guide portion 7 and relays the guide portion 7 and the connecting portion 10 has a substantially arc shape protruding downward. (See FIGS. 2 and 3). The end leg 12 and the relay leg 13 both extend in directions close to each other on the same plane as the plane on which the guide portion 7 is located (on the vertical plane passing through the guide portion 7), and , The mesh body 1 passes through the mesh and contacts the slope N.
検測枠６の左右幅Ｗ（図２参照）は例えば３４ｃｍ程度、高さＨ（図２参照）は例えば１４ｃｍ程度とすることができる。そして、斯かる検測枠６を目安にして硬化材３を吹き付けて法枠４を形成すると、形成後の法枠４の略半円形状の縦断面（芯材２が延びる方向に対し直交する方向の縦断面）の下端幅は３５ｃｍ程度、高さは１５ｃｍ程度となる。 The right and left width W (see FIG. 2) of the inspection frame 6 can be about 34 cm, for example, and the height H (see FIG. 2) can be about 14 cm, for example. Then, when the curing frame 3 is sprayed using the measurement frame 6 as a guide to form the method frame 4, a substantially semicircular longitudinal section of the formed method frame 4 (perpendicular to the direction in which the core material 2 extends). The vertical width of the direction is about 35 cm, and the height is about 15 cm.
また、芯材２及び検測枠６に対して硬化材３を吹き付ける際、芯材２を格子状に配置しておくのであって、その格子の各区画の一辺の長さが１〜２ｍの場合、検測枠６の長さＬ（図３参照）が４０〜５０ｃｍであれば、各辺に一つの検測枠６を配置すれば、その検測枠６が、芯材２を所望の姿勢で保持する機能を発揮するのは勿論、硬化材３を吹き付ける際の吹付け幅及び吹付け高さの目安としての機能も充分に発揮する。 Moreover, when spraying the hardening material 3 with respect to the core material 2 and the measurement frame 6, the core material 2 is arrange | positioned at grid | lattice form, Comprising: The length of one side of each division of the grating | lattice is 1-2 m In this case, if the length L (see FIG. 3) of the measurement frame 6 is 40 to 50 cm, if one measurement frame 6 is arranged on each side, the measurement frame 6 may have the desired core 2. In addition to exhibiting the function of holding in the posture, the function as a guide for the spray width and spray height when spraying the curing material 3 is sufficiently exhibited.
ここで、芯材２が形成する格子の各区画の一辺に対して一つの検測枠６のみで十分な目安機能を発揮するには長さＬが少し足りないといったような場合には、例えば中央ブリッジ部９をより長くした検測枠６を用いて対応してもよいが、例えば二つの目安部７を互いに離間する方向に引っ張り、目安部７を通る鉛直面と連絡部１０とのなす角度θ（図３参照）が大きくなるように連絡部１０の向きを変えることにより、検測枠６を引き延ばして対応することもできる。この連絡部１０の向きを上記のように変える代わりに、あるいは連絡部１０の向きを上記のように変えるとともに、***部８の向きを変えて、***部８の線材末端側に連なる連絡部１０と線材中央側に連なる中央ブリッジ部９とが長さＬ方向に離れるようにしてもよく、この場合も検測枠６の長さＬを伸ばすことができる。 Here, in the case where the length L is a little insufficient to perform a sufficient standard function with only one measurement frame 6 for one side of each section of the grid formed by the core material 2, for example, For example, the measurement frame 6 having a longer central bridge portion 9 may be used. For example, the two reference portions 7 are pulled away from each other, and the vertical plane passing through the reference portion 7 and the connecting portion 10 are formed. By changing the direction of the connecting portion 10 so that the angle θ (see FIG. 3) becomes larger, the measurement frame 6 can be extended to cope with it. Instead of changing the direction of the connecting part 10 as described above, or changing the direction of the connecting part 10 as described above, and changing the direction of the raised part 8, the connecting part 10 connected to the end of the wire of the raised part 8 is connected. Further, the central bridge portion 9 connected to the center side of the wire may be separated in the length L direction. In this case, the length L of the measurement frame 6 can be extended.
このような伸び代を予め蓄えておくという観点から、連絡部１０を直線状に延ばすのではなく、例えば図４（Ａ）に示すようにＬ字状に曲げ、爾後に直線状に延ばせるように構成してあってもよい。但し、連絡部１０を直線状としてある方が、線材（材料）の節約面では有利である。また、同じ観点から、図４（Ｂ）に示すように、角度θが当初は０となるように、目安部７を通る鉛直面上に連絡部１０及び***部８が位置するようにしてあってもよい。但し、目安部７を通る鉛直面から***部８を離し、目安部７の直下から***部８を退避させてある方が、***部８に対する芯材２の結束作業の効率面では有利である。 From the viewpoint of preserving such an allowance in advance, instead of extending the connecting portion 10 in a straight line, for example, it is bent in an L shape as shown in FIG. It may be configured. However, it is more advantageous in terms of saving wire (material) that the connecting portion 10 is linear. Further, from the same viewpoint, as shown in FIG. 4B, the connecting portion 10 and the raised portion 8 are positioned on the vertical plane passing through the reference portion 7 so that the angle θ is initially zero. May be. However, it is advantageous in terms of the efficiency of the bundling work of the core material 2 with respect to the raised portion 8 that the raised portion 8 is separated from the vertical plane passing through the projected portion 7 and the raised portion 8 is retracted from directly below the projected portion 7. .
本実施形態の検測枠６は一本の線材からなり、複数の線材どうしや一線材の異なる部位どうしを連結するための溶接等の連結工程が不要であるので、材料の節約による省資源、コストダウン及び生産の効率化を同時に図ることができる。 The inspection frame 6 of the present embodiment is composed of a single wire, and there is no need for a connecting step such as welding for connecting a plurality of wires or different parts of one wire, so resource saving due to material saving, Cost reduction and production efficiency can be improved at the same time.
また、本実施形態の検測枠６では、芯材２に沿うように検測枠６を配置するにあたり、上述のように、芯材２に直交させる二つの目安部７と二つの***部８の向きに加え、芯材２に平行に延びる中央ブリッジ部９の向きを、検測枠６の向きを決めるときに参照することにより、検測枠６の配置を極めて容易かつ正確に行うことができる。しかも、***部８は目安部７及び沈降部１１の直下から退避した位置にあるとともに、中央ブリッジ部９及び連絡部１０は下方を這うように延び、検測枠６の中央部には上方に開放され作業に適した空間が確保されるので、芯材２を***部８、沈降部１１に結束する作業を効率良く行える。その上、検測枠６が法面Ｎに沈み込むことは、末端脚部１２及び中継脚部１３によって防止されるので、所定高さ及び所定幅を有する法枠４を確実に形成することができる。このように、検測枠６は、簡易吹付け法枠工法（法面保護工法）の施工性の向上に大いに寄与する。 Further, in the measurement frame 6 of the present embodiment, when arranging the measurement frame 6 along the core material 2, as described above, the two reference portions 7 and the two raised portions 8 that are orthogonal to the core material 2. In addition to the orientation, the orientation of the measurement bridge 6 can be arranged very easily and accurately by referring to the orientation of the central bridge portion 9 extending parallel to the core material 2 when determining the orientation of the measurement frame 6. it can. In addition, the raised portion 8 is located at a position retracted from directly below the reference portion 7 and the sinking portion 11, and the central bridge portion 9 and the connecting portion 10 extend so as to crawl downward, and upward in the central portion of the measurement frame 6. Since it is opened and a space suitable for work is secured, the work of binding the core material 2 to the raised portion 8 and the sinking portion 11 can be performed efficiently. In addition, since the inspection frame 6 is prevented from sinking into the slope N by the end legs 12 and the relay legs 13, the frame 4 having a predetermined height and a predetermined width can be reliably formed. it can. Thus, the inspection frame 6 greatly contributes to the improvement of the workability of the simple spray method frame method (slope protection method).
そして、本実施形態の法面保護工法及び構造体では、法枠４内に植生層５を形成するので、法面Ｎが岩盤法面であっても植生の導入が可能となる。 And in the slope protection method and structure of this embodiment, since the vegetation layer 5 is formed in the slope frame 4, vegetation can be introduced even if the slope N is a rock slope.
なお、本発明は、上記の実施の形態に何ら限定されず、本発明の要旨を逸脱しない範囲において種々に変形して実施し得ることは勿論である。例えば、以下のような変形例を挙げることができる。 In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.
法枠４を形成するための硬化材３の吹付け前に、芯材２によって構成された格子の各区画内に養生シート（図示していない）を固定しておき、吹付け後にこれを取り除いてから緑化工を施すようにすれば、各区画内への硬化材３の飛散が予防され、法面Ｎへの植生層５の活着がより良好となる。 A curing sheet (not shown) is fixed in each section of the lattice constituted by the core material 2 before spraying the curing material 3 for forming the method frame 4 and removed after spraying. If the greening work is performed after that, the scattering of the hardener 3 into each section is prevented, and the vegetation layer 5 is more favorably attached to the slope N.
法枠４の各区画内に施す緑化工として、本実施形態では植生基材の吹付けを行っているが、この代わりに、植生マットや飛来種子捕捉マットの設置、埋土種子入り表土の客土といった他の植生基盤の造成手法を採用することもできる。 In this embodiment, vegetation base material is sprayed as a revegetation work to be applied to each section of law frame 4, but instead, vegetation mats and flying seed catching mats are installed, and customers of landfills with buried seeds are used. Other vegetation foundation creation methods such as soil can also be adopted.
法枠４の各区画内の緑化が必要とされないような場合は、緑化工を施す代わりに、各区画内に保護工（例えば硬化材３の吹付け、砕石等の間詰材の充填）を施し、各区画内を保護する保護層（図示していない）を形成するようにしてもよい。この場合、法面Ｎ上には、法枠４と保護層とからなる構造体が構築されることになる。 If greening is not required in each section of law frame 4, instead of applying greening work, a protective work (for example, spraying of hardener 3 and filling of filling material such as crushed stone) is provided in each section. And a protective layer (not shown) for protecting the inside of each compartment may be formed. In this case, on the slope N, a structure composed of the frame 4 and the protective layer is constructed.
検測枠６は、未切断の線材を繰り出しつつその端から順に曲げて所望の形状とした後、線材を切断して検測枠６を得るといった機能を有する線材折曲げ装置を用いる以外に、例えば予め必要な長さに切断された金属線材をプレス機によってプレスして得ることもでき、ポリプロピレンやポリエチレン等を原料として射出成形により所望形状の検測枠６を成形する合成樹脂成形加工機を用いても得ることができる。 In addition to using a wire bending device that has a function of cutting the wire to obtain a desired shape after bending the uncut wire rod in order from the end while feeding out the uncut wire rod. For example, a synthetic resin molding machine that molds an inspection frame 6 having a desired shape by injection molding using a metal wire rod that has been cut to a required length in advance using a press, such as polypropylene or polyethylene as a raw material. It can also be obtained by using.
本実施形態では、各目安部７において沈降部１１を除いた部分を略円弧状としてあるが、これに限らず、目安部７において沈降部１１よりも線材末端側の部分及び線材中央側の部分をそれぞれ、複数（例えば３〜５個）の線分で結んでなる折線状にする、あるいは、沈降部１１を含めた目安部７の全体を複数（例えば８〜１２個）の線分で結んでなる折線状にする、というように、各目安部７において沈降部１１を除いた部分の形状は、硬化材３を吹き付ける際の吹付け幅及び吹付け高さの目安に適する範囲で種々に変更可能である。 In the present embodiment, the portion excluding the settling portion 11 in each guide portion 7 is formed in a substantially arc shape. However, the present invention is not limited to this. Are each formed into a polygonal line formed by connecting a plurality of (for example, 3 to 5) line segments, or the entire reference portion 7 including the settling portion 11 is connected by a plurality of (for example, 8 to 12) line segments. The shape of the portion excluding the settling portion 11 in each guide portion 7 is variously within a range suitable for the guide of the spray width and spray height when spraying the curing material 3. It can be changed.
本実施形態では、***部８を略逆Ｖ字状、沈降部１１を略Ｖ字状に形成しているが、***部８を略逆Ｕ字状、沈降部１１を略Ｕ字状とするなど、これらの形状は芯材２の保持に適する範囲で種々に変更可能である。 In this embodiment, the raised portion 8 is formed in a substantially inverted V shape, and the settling portion 11 is formed in a substantially V shape. However, the raised portion 8 is formed in a substantially inverted U shape and the settling portion 11 is formed in a substantially U shape. These shapes can be variously changed within a range suitable for holding the core material 2.
本実施形態では、末端脚部１２及び中継脚部１３はいずれも、目安部７が位置する平面と同一の平面上（目安部７を通る鉛直面上）に位置しているが、これに限らず、例えば両脚部１２、１３が目安部７と同一の平面上に位置しないように延びていてもよい。但し、両脚部１２，１３が、例えば互いに離間する方向に延びて目安部７の側方に突き出ていると作業の邪魔になり易いので、作業に支障を来さないようにするためには、平面視において二つの目安部７の左右端が計四つの頂点をなす四角形（本実施形態では矩形）の中に納まるように両脚部１２，１３を延ばしておくのが好ましい。 In the present embodiment, both the end leg 12 and the relay leg 13 are located on the same plane (on the vertical plane passing through the reference portion 7) as the plane on which the reference portion 7 is located. For example, both the leg portions 12 and 13 may extend so as not to be positioned on the same plane as the reference portion 7. However, if both the leg portions 12 and 13 extend in a direction away from each other and protrude to the side of the guide portion 7, for example, it is easy to disturb the operation. It is preferable to extend both the leg portions 12 and 13 so that the left and right ends of the two reference portions 7 in a plan view fit in a quadrilateral (rectangular in the present embodiment) having a total of four apexes.
本実施形態ではまた、末端脚部１２及び中継脚部１３が網状体１の目合いを通り抜けて法面Ｎに接するようにしてあるが、両脚部１２，１３が網状体１の目合いを通らない大きさを有していてもよく、例えば、図５に示すように、末端脚部１２を伸ばして末端脚部１２が網状体１の上面に載置されるようにするとともに、中継脚部１３を無くして目安部７に連絡部１０が直に連なるようにしてもよい。 In the present embodiment, the end leg 12 and the relay leg 13 pass through the mesh of the mesh body 1 and contact the slope N, but both the legs 12, 13 pass through the mesh of the mesh body 1. For example, as shown in FIG. 5, the end leg 12 is extended so that the end leg 12 is placed on the upper surface of the mesh body 1, and the relay leg 13 may be eliminated, and the communication unit 10 may be directly connected to the reference unit 7.
上述した以外に、末端脚部１２及び中継脚部１３の形状は種々に変形可能であり、例えば、末端脚部１２を、水平に延ばさず、図２及び図３に示す中継脚部１３のように、下向きに凸の略円弧状を呈するようにしてもよく、さらにその先側（線材末端側）に、網状体１の上面に沿うように水平に延びる部分を設けるようにしてもよい。 In addition to the above, the shapes of the end leg 12 and the relay leg 13 can be variously modified. For example, the end leg 12 does not extend horizontally, as in the relay leg 13 shown in FIGS. In addition, a downwardly convex substantially circular arc shape may be exhibited, and a portion extending horizontally along the upper surface of the net-like body 1 may be provided on the front side (wire material end side).
本実施形態の検測枠６では、中央ブリッジ部９よりも線材一端側の部位と線材他端側の部位とは互いに鏡像の関係となっているが、これに限らず、例えば図６に示すように、中央ブリッジ部９よりも線材一端側の部位と線材他端側の部位と（例えば図３において中央ブリッジ部９よりも手前側の部位と奥側の部位と）の構造が同一であってもよい。図６に示す検測枠６は、線材中央（中央ブリッジ部９の中央）で線材の一端側の部位と他端側の部位とに切断すると、切断して得られる二つの部位は全く同じ形状を呈する（全体が点対称構造を有する）ように構成されている。尚、図６に示す検測枠６の中央ブリッジ部９は、図２及び図３に示す検測枠６の中央ブリッジ部９とは異なり、目安部７を通る鉛直面及び***部８を通る鉛直面に対して直交する方向（芯材２に平行な方向）には延びない。これは、***部８と中央ブリッジ部９との境界部分が左右幅Ｗ（図２参照）方向における中心から外れる位置にあるためである。 In the inspection frame 6 of the present embodiment, the part on the one end side of the wire rod and the part on the other end side of the wire rod are mirror images of each other with respect to the central bridge portion 9. As described above, the structure of the one end side of the wire rod from the central bridge portion 9 and the portion of the other end side of the wire rod (for example, the front portion and the rear portion of the center bridge portion 9 in FIG. 3) are the same. May be. When the inspection frame 6 shown in FIG. 6 is cut into a part on one end side and a part on the other end side of the wire at the center of the wire (center of the central bridge portion 9), the two parts obtained by cutting are exactly the same shape. (The whole has a point-symmetric structure). The central bridge portion 9 of the inspection frame 6 shown in FIG. 6 is different from the central bridge portion 9 of the inspection frame 6 shown in FIGS. 2 and 3 and passes through the vertical plane passing through the reference portion 7 and the raised portion 8. It does not extend in a direction perpendicular to the vertical plane (a direction parallel to the core material 2). This is because the boundary portion between the raised portion 8 and the central bridge portion 9 is at a position deviating from the center in the left-right width W (see FIG. 2) direction.
従って、点対称構造とする（図６参照）よりも検測枠６を面対称構造とする方（図２、図３参照）が、同一の長さＬ（図３参照）を確保しようとした場合に必要となる線材は、中央ブリッジ部９を長さＬ方向に平行に延ばせる分だけ短くなり、材料の節約面で有利となる。しかし、点対称構造とした検測枠６は、鉛直軸まわりに１８０°回転させても全く同一の構造を呈するので、設置時等における取扱利便性の点では有利である。 Therefore, the direction of the inspection frame 6 (see FIGS. 2 and 3) tries to secure the same length L (see FIG. 3) rather than the point symmetry structure (see FIG. 6). The wire necessary in this case is shortened by an amount that allows the central bridge portion 9 to extend in parallel with the length L direction, which is advantageous in terms of material saving. However, since the inspection frame 6 having a point-symmetric structure exhibits exactly the same structure even when rotated 180 ° around the vertical axis, it is advantageous in terms of handling convenience during installation.
中央ブリッジ部９に、下方の芯材２を浮設保持するための***部８を追加して設けてもよい。また、予めまたは検測枠６の設置時等に、中央ブリッジ部９に、単数あるいは複数の上または下に凸の屈曲部分を設けて、検測枠６の剛性を高めたり、検測枠６が法面Ｎの凹凸に一層沿うようにしたりしてもよい。 A raised portion 8 for floatingly holding the lower core member 2 may be additionally provided in the central bridge portion 9. In addition, when the inspection frame 6 is installed in advance or the like, the central bridge portion 9 is provided with one or more convex bent portions above or below to increase the rigidity of the inspection frame 6 or to increase the inspection frame 6. May be further along the unevenness of the slope N.
本実施形態では、二本一対かつ上下二段構えに配置する芯材２を各検測枠６に保持させるが、下方の芯材２のみを用いる（上方の芯材２を用いない）場合もあり、この場合、上方の芯材２を保持するための沈降部１１は不要となるので、図７（Ａ）及び（Ｂ）に示すように省略することができる。尚、この場合の検測枠６の左右幅Ｗ（図７（Ｂ）参照）は例えば２９ｃｍ程度、高さＨ（図７（Ｂ）参照）は例えば９ｃｍ程度とすることができ、そうすると、形成される法枠４の縦断面の下端幅は３０ｃｍ程度、高さは１０ｃｍ程度となる。 In the present embodiment, the core materials 2 arranged in a pair of two pairs and in the upper and lower stages are held in each measurement frame 6, but only the lower core material 2 is used (the upper core material 2 is not used). In this case, the settling portion 11 for holding the upper core member 2 is unnecessary, and can be omitted as shown in FIGS. 7 (A) and 7 (B). In this case, the right and left width W (see FIG. 7B) of the inspection frame 6 can be about 29 cm and the height H (see FIG. 7B) can be about 9 cm, for example. The bottom width of the vertical section of the method frame 4 is about 30 cm and the height is about 10 cm.
本実施形態では、二本一対かつ上下二段構えに配置する芯材２を各検測枠６に保持させるが、芯材２を三本一対かつ上下二段構えに配置する（一本の上方の芯材２と、水平方向に平行に離れた二本の下方の芯材２とを用いる）場合もあり、この場合、下方の芯材２を保持するために各連絡部１０と中央ブリッジ部９との間に設ける***部１１は二つ必要となるので、図８（Ａ）及び（Ｂ）に示すように、例えばスペーサ部１４を介して***部１１を二つ設ければよい。尚、この場合の検測枠６の左右幅Ｗ（図８（Ｂ）参照）は例えば３４ｃｍ程度、高さＨ（図７（Ｂ）参照）は例えば１９ｃｍ程度とすることができ、そうすると、形成される法枠４の縦断面の下端幅は３５ｃｍ程度、高さは２０ｃｍ程度となる。 In the present embodiment, the core material 2 arranged in a pair of two and vertically in two stages is held in each measurement frame 6, but the core material 2 is arranged in a pair of three and vertically in two stages (one upper part) And two lower cores 2 separated in parallel in the horizontal direction), and in this case, each connecting portion 10 and the central bridge portion are used to hold the lower core material 2. Since two raised portions 11 provided between the two raised portions 9 are required, for example, two raised portions 11 may be provided via a spacer portion 14 as shown in FIGS. In this case, the right and left width W (see FIG. 8B) of the measurement frame 6 can be about 34 cm and the height H (see FIG. 7B) can be about 19 cm, for example. The bottom width of the vertical section of the method frame 4 is about 35 cm and the height is about 20 cm.
ここで、図８（Ａ）及び（Ｂ）には、下方の芯材２が二本となる場合を示しているが、下方の芯材２を三本以上用いる場合もあり、その場合は、例えば下方の芯材２の本数にあわせて***部８の数を増やせばよく、また、スペーサ部１４は必ずしも設けなくてもよい。 Here, FIGS. 8A and 8B show a case where the lower core material 2 is two, but there are cases where three or more lower core materials 2 are used, in which case For example, the number of the raised portions 8 may be increased in accordance with the number of the core materials 2 below, and the spacer portion 14 is not necessarily provided.
また、図８（Ａ）及び（Ｂ）に示す検測枠６では、各連絡部１０と中央ブリッジ部９との間に設ける二つの***部８とスペーサ部１４とは、同一の鉛直面内に位置するようにしてあるが、図８（Ａ）では中央ブリッジ部９と直交する方向に延びるスペーサ部１４の向きを変えて、二つの***部８が長さＬ方向に離れるようにしてもよい。この場合、各***部８を通る鉛直面は、目安部７を通る鉛直面に平行となっていてもよいし、なっていなくてもよい。 Further, in the measurement frame 6 shown in FIGS. 8A and 8B, the two raised portions 8 and the spacer portion 14 provided between each connecting portion 10 and the central bridge portion 9 are in the same vertical plane. In FIG. 8A, the direction of the spacer portion 14 extending in the direction orthogonal to the central bridge portion 9 is changed so that the two raised portions 8 are separated in the length L direction. Good. In this case, the vertical plane passing through each raised portion 8 may or may not be parallel to the vertical plane passing through the reference portion 7.
本実施形態では、一本の下方の芯材２を保持させるための***部８を、中央ブリッジ部９を挟んで線材一端側及び線材他端側にそれぞれ一つずつ設けている、すなわち、***部８を計二つ設けているが、図９（Ａ）及び（Ｂ）に示すように、***部８を一つのみ設け、線材（材料）の節約面でより有利となるようにしてもよい。尚、図示例では、二つの目安部７は、平面視において二つの目安部７の左右端が計四つの頂点をなす矩形（四角形の一例）の２本の対角線の一方によって結ばれることになる端部同士のみが連絡部１０及び***部８を介して繋がっている（換言すれば、二つの目安部７の末端脚部１２同士が相対しないようになっている）。また、連絡部１０は、平面視において***部８を二つの目安部７の間に位置させるように各目安部７側から***部８側に向けて直線状に延び、かつ、検測枠６の全体の長さが最小限となるように長さＬ（図３参照）方向に対して斜めに延びている。そして、図示例では、線材中央よりも線材一端側の部位と線材他端側の部位との構造が同一（全体が点対称構造）である。ここで、図示例では、中央ブリッジ部９は設けられていないと捉えることもできるし、***部８が中央ブリッジ部９を兼用している、あるいは中央ブリッジ部９に***部８を設けてあると捉えることもできる。 In the present embodiment, one raised portion 8 for holding one lower core member 2 is provided on each of one end of the wire and the other end of the wire across the central bridge portion 9, that is, the raised portion. Although a total of two portions 8 are provided, as shown in FIGS. 9A and 9B, only one raised portion 8 is provided so as to be more advantageous in terms of saving wire (material). Good. In the illustrated example, the two guide portions 7 are connected by one of two diagonal lines of a rectangle (an example of a quadrangle) in which the left and right ends of the two guide portions 7 form a total of four vertices in plan view. Only the end portions are connected via the connecting portion 10 and the raised portion 8 (in other words, the end leg portions 12 of the two guide portions 7 are not opposed to each other). The connecting portion 10 extends linearly from each guide portion 7 side toward the raised portion 8 side so that the raised portion 8 is positioned between the two guide portions 7 in plan view, and the inspection frame 6 Is extended obliquely with respect to the direction of the length L (see FIG. 3) so that the overall length of the head is minimized. And in the example of illustration, the structure of the wire rod one end side and the wire rod other end side portion from the wire rod center is the same (the whole is a point symmetrical structure). Here, in the illustrated example, it can be understood that the central bridge portion 9 is not provided, and the raised portion 8 also serves as the central bridge portion 9, or the raised portion 8 is provided in the central bridge portion 9. It can also be taken as.
同様に、水平方向に平行に離れた二本の下方の芯材２を用いる場合、図１０（Ａ）及び（Ｂ）に示すように、***部８を二つのみ設けるようにしてもよい。尚、図示例ではスペーサ部１４を設けているが、スペーサ部１４は無くてもよい。そして、図示例では、中央ブリッジ部９は設けられていないと捉えることもできるし、スペーサ部１４が中央ブリッジ部９を兼用している、あるいは中央ブリッジ部９に***部８及びスペーサ部１４を設けてあると捉えることもできる。 Similarly, when two lower core members 2 separated in parallel to the horizontal direction are used, only two raised portions 8 may be provided as shown in FIGS. Although the spacer portion 14 is provided in the illustrated example, the spacer portion 14 may not be provided. In the illustrated example, it can be understood that the central bridge portion 9 is not provided, the spacer portion 14 also serves as the central bridge portion 9, or the raised portion 8 and the spacer portion 14 are provided on the central bridge portion 9. It can also be understood that it is provided.
下方の芯材２を三本以上用いる場合には、図９（Ａ）及び（Ｂ）、図１０（Ａ）及び（Ｂ）に示す例と同様に、例えば、下方の芯材２の本数と同数の***部８を設けるようにすることができる。また、図９（Ａ）及び（Ｂ）、図１０（Ａ）及び（Ｂ）に示す例では、***部８が、目安部７を通る鉛直面と平行な鉛直面上に位置するようにしているが、これに限らず、例えば、図１１に示すように、二つの目安部７の間に位置する中間部分１５が平面視において直線状に延びるようにし、その中間部分１５に***部８を設け、線材（材料）の節約面で一層有利となるようにしてもよい。 When three or more lower core members 2 are used, for example, the number of lower core members 2 is the same as the example shown in FIGS. 9A and 9B and FIGS. 10A and 10B. The same number of raised portions 8 can be provided. Moreover, in the example shown to FIG. 9 (A) and (B), FIG. 10 (A) and (B), it is made for the protruding part 8 to be located on the vertical plane parallel to the vertical plane which passes along the reference | standard part 7. FIG. However, the present invention is not limited to this. For example, as shown in FIG. 11, an intermediate portion 15 positioned between two guide portions 7 extends linearly in a plan view, and a raised portion 8 is formed on the intermediate portion 15. It may be provided to be more advantageous in terms of saving wire (material).
図８（Ａ）及び（Ｂ）、図１０（Ａ）及び（Ｂ）に示す例では、各***部８はそれぞれ一本の下方の芯材２のみを保持するようにしているが、これに限らず、例えば図１２に示すように、一つの***部８に、水平方向に平行に離れた二本の下方の芯材２をともに保持させるようにしてもよい。すなわち、図示例では、***部８の上部の左右にそれぞれ一本ずつ下方の芯材２を保持させることができる。 In the example shown in FIGS. 8A and 8B and FIGS. 10A and 10B, each raised portion 8 is configured to hold only one lower core member 2. For example, as shown in FIG. 12, two ridges 8 that are separated in parallel to the horizontal direction may be held together in one ridge 8. That is, in the illustrated example, the lower core member 2 can be held one by one on the left and right of the upper portion of the raised portion 8.
上記各例では、検測枠６が一本の線材からなるが、これに限らず、例えば図１３及び図１４に示すように、複数の線材を接合（溶接等）して検測枠６を構成してもよい。ここで、図１３は２本の線材により、図１４は３本の線材により、それぞれ検測枠６を構成した例を示す。そして、図１３、図１４に示す例のように、検測枠６を複数の線材によって構成した場合であっても、検測枠６の一端から他端までの基幹ルート（最短ルート）が、複数箇所で曲がった一本の線材からなるとみなすことができる場合、すなわち、検測枠６の一端から他端までの間に存在する線材どうしの接合箇所が一つのみであるか、または複数であってもそれらが直列関係にあり、並列関係にはない場合であれば、用いる線材の本数を減らすと共に、溶接等の連結に必要な工数を削減して、材料の節約による省資源、コストダウン及び生産の効率化を同時に図ることができる。 In each of the above examples, the inspection frame 6 is composed of a single wire. However, the present invention is not limited to this. For example, as shown in FIGS. 13 and 14, a plurality of wires are joined (welded or the like) to the inspection frame 6. It may be configured. Here, FIG. 13 shows an example in which the inspection frame 6 is constituted by two wires, and FIG. 14 is constituted by three wires. And even if it is a case where inspection frame 6 is constituted by a plurality of wires like the example shown in FIGS. 13 and 14, the basic route (shortest route) from one end to the other end of inspection frame 6 is When it can be regarded as consisting of a single wire bent at a plurality of locations, that is, there is only one joint between the wires existing from one end to the other end of the measurement frame 6, or a plurality Even if they are in a series relationship and not in a parallel relationship, the number of wires used is reduced, and the man-hours required for connection such as welding are reduced, saving resources and reducing costs by saving materials. And production efficiency can be improved at the same time.
