Description
この発明は、検測枠の製造方法および検測枠ならびに法面保護工法に関するものである。 The present invention relates to a method for manufacturing a measurement frame, a measurement frame, and a slope protection method.
法面に配置した鉄筋の上に被せるように法面上に配置した検測枠に前記鉄筋を固定し、その鉄筋にモルタルまたはコンクリートを吹き付けて法枠を形成するために使用される、法枠の形状寸法を規制するための検測枠として、下記特許文献１に示すものがある。 The frame used to form the frame by fixing the reinforcing bar to the inspection frame placed on the slope so as to cover the reinforcing bar placed on the slope and spraying the reinforcing bar with mortar or concrete. As a measurement frame for regulating the shape dimension of the above, there is one shown in Patent Document 1 below.
これは、所定の高さと幅とを有し、かつ正面視ほぼ弓形状の一対の第１部材（目安部材）と、この第１部材どうしを連結する第２部材を備えるとともに、第１部材の高さ方向中間部において第２部材上に鉄筋を浮設保持する鉄筋保持部材を二本、長さ方向に直角な方向に横設したもので、第１部材は、長さ方向に適宜の間隔をおいて鉄筋を跨いで配置される。これら第１部材、第２部材、鉄筋保持部材は、例えば防錆加工を施した適宜太さの針金を含む鉄線材等の鋼製線材よりなる。そして、第１部材と第２部材とは、溶接またはハンダ付けによって連結（接続）されている。また、二本の鉄筋保持部材は、それぞれ一対の第２部材上に架け渡すように溶接により連結（接続）されている。 This includes a pair of first members (reference members) having a predetermined height and width and having a substantially bow shape when viewed from the front, and a second member for connecting the first members to each other. Two reinforcing bar holding members that float and hold the reinforcing bar on the second member in the middle in the height direction are horizontally arranged in a direction perpendicular to the length direction, and the first member has an appropriate interval in the length direction. It is arranged across the rebar. The first member, the second member, and the reinforcing bar holding member are made of a steel wire such as an iron wire including a wire having an appropriate thickness subjected to rust prevention, for example. And the 1st member and the 2nd member are connected (connected) by welding or soldering. Further, the two reinforcing bar holding members are connected (connected) by welding so as to be bridged over the pair of second members.
また、法枠の形状寸法を規制するとともに、鉄筋を浮設保持する検測枠として、下記特許文献２に示す閉曲線状に形成されたものがある。これは、一本の線材を湾曲または折曲することにより形成されている。 In addition, there is an inspection frame that regulates the shape and size of the normal frame and floats and holds a reinforcing bar and is formed in a closed curve shape shown in Patent Document 2 below. This is formed by bending or bending one wire.
特許文献１に記載されている検測枠は、例えば格子状法枠の各辺に一つ設けてあればよく、少ない労力で配置作業を容易に行えるけれども、多数本の鉄線材等の鋼製線材を溶接するなどの連結（接続）手段を用いて所望する形状としており、線材連結（接続）工程が必要な分コストがかかるといった課題がある。すなわち、一対の第１部材（目安部材）と、一対の第２部材と、一対の鉄筋保持部材との計６個の鋼製線材が必要で、かつこれら鋼製線材の溶接等の連結（接続）箇所が８箇所も必要である。また、特許文献２に記載されている検測枠は、特許文献１に記載されている検測枠に比べて長さ方向に極めて短い寸法を有するので、法枠の形状寸法を規制する機能と鉄筋を浮設保持する機能を発揮させるには、すなわち、所定形状寸法および所定強度の法枠を確実に形成するには、例えば格子状法枠の各辺に少なくとも二つ設ける必要があり、配置に関して特許文献１に記載されている検測枠に比べて作業性（施工性）が悪いといった課題がある。また、特許文献２に記載されている検測枠は、所望する形状をうるために一本の線材を閉曲線状に形成する作業が、その３次元に入り組んだ形状から線材加工機では不可能であり、実用化されていない。 The inspection frame described in Patent Document 1 only needs to be provided, for example, on each side of the grid-like method frame, and can be easily arranged with a small amount of labor. There is a problem that a desired shape is obtained by using a connecting (connecting) means such as welding the wire, and a cost is required for the wire connecting (connecting) step. That is, a total of six steel wire rods including a pair of first members (reference members), a pair of second members, and a pair of reinforcing bar holding members are necessary, and the connection (connection) of these steel wire rods is required. ) 8 locations are also required. In addition, the inspection frame described in Patent Document 2 has an extremely short dimension in the length direction as compared to the inspection frame described in Patent Document 1, and thus has a function of regulating the shape dimension of the normal frame. In order to exert the function to float and hold the reinforcing bar, that is, to form a frame with a predetermined shape and a predetermined strength reliably, it is necessary to provide at least two on each side of the lattice-shaped frame, for example. There is a problem that workability (workability) is poor as compared with the inspection frame described in Patent Document 1. In addition, the inspection frame described in Patent Document 2 cannot perform the work of forming a single wire in a closed curve shape in order to obtain a desired shape because of its three-dimensionally complicated shape with a wire processing machine. Yes, not put into practical use.
この発明は、溶接などの線材接続工程を不要あるいは極力少なくすることができ、必要最小限の材料でコスト安に得ることができるとともに、少ない労力で作業性の良好な、法面の凹凸に良くなじませることができる検測枠の製造方法および検測枠ならびに法面保護工法を提供することである。 This invention can eliminate the wire connecting process such as welding as much as possible, can be obtained at a low cost with the minimum necessary material, and has good workability with less labor and good for unevenness on the slope. The object is to provide a method of manufacturing a measurement frame, a measurement frame, and a slope protection method that can be adapted.

In this case, the upper core member may or may not be arranged on the slope in advance before the measurement frame is installed. The hardening material in this invention means the sand etc. which mixed mortar, concrete, and an adhesive agent. When using a reinforcing bar as the core and forming a mortar or concrete bulge, a metal (metal wire) is preferable as the wire for the inspection frame, but a lightweight fiber is used as the core and bonded. When using a hardener that does not contain cement using an agent, it is preferable to use a measurement frame made of synthetic resin. When the inspection frame is made of a synthetic resin, any material that can be easily molded, such as polypropylene or polyethylene, can be used.
さらに、この発明は、最初に、法面に被覆材を展開する工程を有する請求項５に記載の法面保護工法を提供する（請求項６）。この発明における被覆材とは、金網、樹脂ネット、簾状の高張力繊維など地山を直接被覆するものをいう。法面は平滑ではなく凹凸があることが多く、その場合、図２，４，５に示すように金網（被覆材の一例）は少し（例えば１〜２ｃｍ程度）浮いた状態となる。なお、被覆材は法面に当接してもよいし、法面から適当間隔空けて張設されてもよい。また、法面の勾配が緩いなど、法表面が比較的安定している場合等には、前記被覆材（被覆体）を省略することもできる。 Furthermore, the present invention initially provide a slope protection method of claim 5 including the step of deploying the dressing slope (claim 6).

本発明では、以下の効果を奏する。
（１）特許文献１に記載された従来の検測枠（以下、従来技術という）では、１本の芯材を固定（浮設保持）する機能を有する検測枠において、鋼製線材が６本も必要で、しかもこれら鋼製線材の溶接等の線材連結（接続）箇所が８箇所にも及んでおりコスト高となる。一方、本発明では、少なくとも上側１本、下側１本の芯材を固定する機能を有するのに前記従来技術のように６本もの多数の鋼製線材を必要とせず、コストダウンが達成できる。また、所定形状寸法および所定強度の膨出体を確実に形成することができる検測枠を得るために必要な線材量が、一例として前記従来技術では２４５ｃｍのところ、本発明で得られる検測枠では１９５ｃｍと約２０％少なく済み、使用材料の面からもコストダウンが達成できる。
The present invention has the following effects.
(1) Patent Document 1 conventional test Hakawaku (hereinafter prior referred art) described in the in test Hakawaku having a function of fixing a single core material (浮設retention), the steel wire rod Six are also required, and the number of wire connecting (connecting) locations such as welding of these steel wires reaches as many as eight, resulting in high costs. On the other hand, in the present invention, not least the upper one, requires a large number of steel wire rod is also six as in the prior art to have a function of fixing the lower one core material, cost reductions can be achieved . Moreover, the amount of wire necessary for obtaining a measurement frame capable of reliably forming a bulging body having a predetermined shape and a predetermined strength is, for example, 245 cm in the above-mentioned prior art, and the measurement obtained by the present invention. The frame is 195 cm, which is about 20% less, and the cost can be reduced in terms of the material used.
（２）例えば図１１〜１８に示すように、１個の検測枠には、前記二つの接続部１０’，１０’’を介して膨出体形状の目安となる第１，２傾斜部（５，７）と第３，４傾斜部（１３，１５）が検測枠の長さ方向（両矢印Ｄで示す方向）に適宜間隔をおいて対向配置されることになる。また、例えば図１，３，６，７，９に示すように、第２略Λ部と第３略Λ部を接続する接続部の存在により、膨出体形状の目安となる第１，２傾斜部と第３，４傾斜部が検測枠の長さ方向（両矢印Ｄで示す方向）に適宜間隔をおいて対向配置されることになる。そして、例えば図１，３，６，７，９に示すものにおいては、対向するこれら傾斜部に、それぞれ、第１略Ｖ部および第２略Ｖ部を設け、対向するこれら傾斜部の側に、それぞれ、第１略Λ部、第２略Λ部および第３略Λ部、第４略Λ部を設けている。そのため、例えば格子状の膨出体を形成する際、格子状芯材の一辺にこの発明の検測枠を１個設置するだけで、１本の上側芯材を第１略Ｖ部と第２略Ｖ部の二箇所で固定（位置決め）することができるので、また、２本の下側芯材もそれぞれ第１略Λ部〜第４略Λ部のいずれか二箇所で固定（位置決め）することができるので、例えば一個の検測枠の設置で例えば上側１本、下側２本の芯材がそれぞれ一箇所で固定（位置決め）されるような検測枠に比べて硬化材の盛りつけ作業をし易くできるとともに、例えば上側１本、下側２本の芯材をそれぞれ二箇所で固定（位置決め）することができるので、所定形状寸法および所定強度の膨出体を確実に形成することができる。 (2) For example, as shown in FIGS. 11 to 18, the first and second inclined portions that serve as a measure of the bulging body shape are provided in one measurement frame via the two connection portions 10 ′ and 10 ″. (5, 7) and the third and fourth inclined portions (13, 15) are arranged to face each other at an appropriate interval in the length direction of the measurement frame (the direction indicated by the double arrow D). For example, as shown in FIGS. 1, 3, 6, 7, and 9, the first and second bulges can be used as a guide for the shape of the bulging body due to the presence of the connecting portion that connects the second substantially Λ portion and the third substantially Λ portion. The inclined portion and the third and fourth inclined portions are disposed to face each other with an appropriate interval in the length direction of the measurement frame (the direction indicated by the double arrow D). For example, in the ones shown in FIGS. 1, 3, 6, 7, and 9, the first substantially V portion and the second substantially V portion are provided on the opposed inclined portions, respectively, on the opposite inclined portions side. , A first substantially Λ portion, a second substantially Λ portion, a third substantially Λ portion, and a fourth substantially Λ portion, respectively. Therefore, for example, when forming a grid-like bulging body, only one inspection frame of the present invention is installed on one side of the grid-like core material, and one upper core material is connected to the first substantially V portion and the second portion. Since it can be fixed (positioned) at approximately two portions of the V portion, the two lower core members are also fixed (positioned) at any one of the first approximately Λ portion to the fourth approximately Λ portion. So, for example, installation of one inspection frame, for example, the upper one and lower two core materials are fixed (positioned) in one place, respectively, compared to the measurement frame, the work of placing the curing material For example, since the upper one core and the lower two cores can be fixed (positioned) at two locations, respectively, it is possible to reliably form a bulging body having a predetermined shape and a predetermined strength. it can.
（３）そして、格子状芯材の一辺が長くなっても、その長さに応じて、例えば図１，３，６，７，９に示すものでは、第１略Λ部と第２略Λ部を接続する接続部を辺方向に沿って適宜の長さに設定することができることから、格子状芯材の一辺に検測枠を複数個設ける必要はなく、その分経済的である。また、図１１〜１８に示すものにおいては、前記二つの接続部１０’，１０’’を適宜の長さに設定することができることから、格子状芯材の一辺に検測枠を複数個設ける必要はなく、その分経済的である。 (3) Even if one side of the grid-like core material becomes longer, the first substantially Λ portion and the second substantially Λ are formed according to the length, for example, as shown in FIGS. Since the connecting portion for connecting the portions can be set to an appropriate length along the side direction, it is not necessary to provide a plurality of measurement frames on one side of the grid-like core material, which is economical.

而して、線材折曲げ装置において、一本の線材Ｒを前記第一工程、第二工程・・・第十工程および第十一工程の順序で折曲して、所望形状の検測枠１をうる。そして、予め整形された法面２に目合いが例えば５〜６ｃｍ程度の菱形金網Ｋなどの被覆材を敷設し、アンカー（図示せず）を適宜の間隔で法面２に打ち込んで金網Ｋを法面２に固定する。次に、金網Ｋの上に、直径が例えば６〜１０ｍｍ程度の鉄筋３，４を一辺Ｌが１〜２ｍ程度の略正方形の格子状に組み合わせて配置する。そして、鉄筋３，４からなる格子状の各辺のほぼ中央に線材折曲げ装置で得られた検測枠１を、その円弧形状部分Ａ，Ａが鉄筋３，４を跨ぐようにして、金網Ｋの上に配置する。この実施形態では、脚２０の凹状部２４、脚２１の凹状部２４’、脚２１、脚２３は法面２に載った状態で、前記接続部１０、水平辺部３０，３０’、水平辺部２５，２５’および連設部分７ａ，７ａ’が金網Ｋの上面ｉに接しながら検測枠１が配置されるが、場合に応じて検測枠１の配置の仕方は適宜変わりうる。この検測枠１は、モルタルなど１７を吹き付け幅および吹き付け幅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、この実施形態のように、辺の長さＬ（図１参照）が１〜２ｍ、検測枠１の長さＱが４０〜５０ｃｍのときは、各辺に一つの検測枠１を設けるだけでよい。また、前記辺の長さＬがより大きいときは、検測枠１の長さＱをより大きくすればよい。すなわち、前記接続部１０の長さをより大きくした検測枠１を用いればよい。そして、この実施形態では、前記接続部１０を金網Ｋの上面ｉに接するような低い位置に形成してあり、結束・固定作業を行う作業空間が開放されているため、検測枠１内に作業者は手を入れやすく鉄筋３および４それぞれの前記第１略Ｖ部６，第２略Ｖ部１４および第１略Λ部９、第２略Λ部１１への挿入および挿入された鉄筋３および４の前記第１略Ｖ部６，第２略Ｖ部１４および第１略Λ部９、第２略Λ部１１への固定等の挿入・結束・固定作業が容易になる。以上のように構成した格子状鉄筋３，４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１７をモルタルガン機などの土木用吹付機によって吹き付ける。この場合、鉄筋３，４によって形成される格子枠の各辺には、モルタルなど１７の吹き付け幅および吹き付け高さの目安となる検測枠１を設けてあるので、この検測枠１にしたがってモルタルなど１７の吹き付けを行うだけで、所定寸法のモルタルなど１７よりなる格子状法枠Ｍを容易に形成することができる。すなわち、この実施形態においては、下端幅３５ｃｍ、高さ１５ｃｍ程度の格子状法枠Ｍ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Ｍを確実に形成することができる。続いて、格子状法枠Ｍの枠内に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Ｊ（法面２から３〜５ｃｍ程度の厚み）を形成することにより、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２の景観の向上および植生の根や茎などによる法面２の恒久的安定に寄与するところが大きい。この場合、格子状法枠Ｍを形成するモルタルなど１７の吹き付けを行う前に、枠内の地山（法面）２にモルタルなど１７が付着しないように保護するシートを設置しておき、格子状法枠Ｍを形成後、植生材料を吹き付ける前に前記シートを撤去することにより、吹き付け導入した植生の地山（法面）２への活着が良好となる。また、格子状法枠Ｍの枠内の緑化が必要とされない場合は、枠内にモルタルなど１７を吹き付けたり、砕石などの間詰材で覆うことにより、法枠間の地山（法面）２の保護が可能である。 Thus, in the wire bending apparatus, one wire R is bent in the order of the first step, the second step, the tenth step and the eleventh step, and the inspection frame 1 having a desired shape is obtained. Get. Then, a covering material such as a rhombus metal mesh K having a mesh of about 5 to 6 cm, for example, is laid on the pre-shaped slope 2 and an anchor (not shown) is driven into the slope 2 at an appropriate interval to form the wire mesh K. Fix to slope 2. Next, the reinforcing bars 3 and 4 having a diameter of, for example, about 6 to 10 mm are combined and arranged on the wire mesh K in a substantially square lattice shape having a side L of about 1 to 2 m. Then, the inspection frame 1 obtained by the wire bending device is arranged at the approximate center of each grid-like side composed of the reinforcing bars 3 and 4 so that the arc-shaped portions A and A straddle the reinforcing bars 3 and 4 and the wire mesh. Place on K. In this embodiment, the concave portion 24 of the leg 20, the concave portion 24 ′ of the leg 21, the leg 21 and the leg 23 are placed on the slope 2, and the connecting portion 10, the horizontal side portions 30 and 30 ′, and the horizontal side The measurement frame 1 is arranged with the portions 25, 25 ′ and the continuous portions 7a, 7a ′ being in contact with the upper surface i of the wire mesh K. However, the arrangement of the measurement frame 1 can be appropriately changed according to circumstances. Since this inspection frame 1 serves as a guide for the spray width and spray width height of the mortar 17 or the like, it is sufficient that at least one is provided on each side of the lattice frame. When the length L (see FIG. 1) is 1 to 2 m and the length Q of the measurement frame 1 is 40 to 50 cm, it is only necessary to provide one measurement frame 1 on each side. Further, when the side length L is larger, the length Q of the inspection frame 1 may be made larger. That is, the inspection frame 1 in which the length of the connecting portion 10 is made larger may be used. And in this embodiment, since the said connection part 10 is formed in the low position which touches the upper surface i of the metal-mesh K, and the work space which performs a bundling and fixing work is open | released, in the measurement frame 1 The operator can easily put his hands into the first substantially V portion 6, the second substantially V portion 14, the first substantially Λ portion 9 and the second substantially Λ portion 11 of each of the reinforcing bars 3 and 4, and the inserted reinforcing bars 3. And 4 of the first substantially V portion 6, the second substantially V portion 14, the first substantially Λ portion 9, and the second substantially Λ portion 11 can be easily inserted, bound, and fixed. For example, a low slump mortar having a moisture content of about 7 to 8% is sprayed on the grid-like reinforcing bars 3 and 4 configured as described above by a civil engineering sprayer such as a mortar gun machine. In this case, a measurement frame 1 serving as a guide for the spray width and spray height of 17 such as mortar is provided on each side of the lattice frame formed by the reinforcing bars 3 and 4. By simply spraying 17 such as mortar, a lattice method frame M made of 17 having a predetermined size can be easily formed. In other words, in this embodiment, the lattice-like method frame M having a lower end width of 35 cm and a height of about 15 cm can be formed, and the lattice-like method frame M having a predetermined size and a predetermined strength can be reliably formed. Subsequently, the vegetation material is sprayed into the frame of the grid-like method frame M by using a power sprayer or the like to form a vegetation layer J (thickness of about 3 to 5 cm from the slope 2). It is also possible to introduce vegetation into the slope, which greatly contributes to the improvement of the landscape of slope 2 and the permanent stability of slope 2 due to the roots and stems of the vegetation. In this case, before spraying the mortar and the like 17 forming the grid-like frame M, a sheet for protecting the mortar and the like 17 from adhering to the ground (slope) 2 in the frame is installed, After forming the shape method frame M, before the vegetation material is sprayed, the sheet is removed, so that the vegetation introduced by spraying can be well attached to the natural ground (slope) 2. In addition, when greening in the frame of the grid-like frame M is not required, the ground between the frame frames (slope) by spraying 17 with mortar or the like in the frame or covering with a padding material such as crushed stone. Two protections are possible.

図３０は、検測枠を構成する線材を、第２傾斜部から第３傾斜部に至る間の位置で３分割された三つの線材部分より構成している第１７の実施形態を示している。この実施形態では、三つの線材部分Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３’’’を用いており、得られた検測枠１’は、略Λ部９’への接続部１０’の水平辺部３０における適宜の箇所と第３傾斜部１３への接続部１０’’の水平辺部３０’における適宜の箇所の二箇所に溶接ポイントＺ２ を有している。図３０において、１０’ａおよび１０’’ａはそれぞれ線材部分Ｒ１ ’’’および線材部分Ｒ２’’’の一端であり、１０’ｂおよび１０’’ｂはそれぞれ線材部分Ｒ３ ’’’の一端および他端であり、これらが溶接箇所である。１’は、前記溶接ポイントＺ２ で溶接された後に得られる検測枠である。この実施形態でも、上記第１４〜１６の実施形態と同様の利点を有する。すなわち、例えば前記線材折曲げ装置を用いて予め三つの線材部分Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３ ’’’を形成しておき、その後、線材部分Ｒ３ ’’’の両端１０’ｂおよび１０’’ｂにそれぞれ線材部分Ｒ１ ’’’の一端１０’ａおよび線材部分Ｒ２ ’’’の一端１０’’ａを溶接して三者Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３ ’’’を連結し、一本の線材としている。そして、上記第１の実施形態のように、線材折曲げ装置を用いて連続で製造するより、この実施形態のように一つの検測枠１’を得るのに三つの線材部分（３分割した部品）Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３ ’’’を用いる方が線材部分（３分割した部品）Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３ ’’’の製造スピードを上げることができ、また、線材部分（３分割した部品）Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３ ’’’の形状が歪み難いという利点を有する。すなわち、この実施形態では、３分割した部品Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３ ’’’の形成後に、三者Ｒ１ ’’’，Ｒ２ ’’’，Ｒ３ ’’’を溶接して接続し、それによって一つの検測枠１’を得るので、連続して一つの検測枠を製造する上記第１の実施形態より、各部品Ｒ１’’’，Ｒ２ ’’’，Ｒ３ ’’’の製造スピードと形状の安定性を上げることができ、最終的な形状の修正作業が少なく済むといった利点を有する。なお、溶接ポイントＺ２ は水平辺部３０，３０’の箇所に限定されるものではなく溶接ポイントＺ２ は第２傾斜部７から第３傾斜部１３に至る間の位置であればよく、また、溶接ポイントＺ２ を３以上に設定してもよい。 Figure 30, the wire constituting the detection Hakawaku shows a seventeenth embodiment of the 3 that make up more divided three wire portion at a position between reaching the third inclined portion from the second inclined portion . In this embodiment, three wire portions R1 ′ ″, R2 ′ ″, R3 ′ ″ are used, and the obtained inspection frame 1 ′ is substantially the connection portion 10 ′ to the Λ portion 9 ′. Welding points Z2 are provided at two locations, an appropriate location on the horizontal side portion 30 and an appropriate location on the horizontal side portion 30 ′ of the connecting portion 10 ″ to the third inclined portion 13. In FIG. 30, 10′a and 10 ″ a are one ends of the wire portion R1 ′ ″ and the wire portion R2 ′ ″, respectively, and 10′b and 10 ″ b are one ends of the wire portion R3 ′ ″, respectively. And the other end, which are the welds. 1 'is a measurement frame obtained after welding at the welding point Z2. This embodiment has the same advantages as those of the fourteenth to sixteenth embodiments. That is, for example, three wire portions R1 ′ ″, R2 ′ ″, R3 ′ ″ are formed in advance using the wire bending apparatus, and then both ends 10′b of the wire portion R3 ′ ″ and One end 10′a of the wire portion R1 ′ ″ and one end 10 ″ a of the wire portion R2 ′ ″ are welded to 10 ″ b, respectively, so that the three members R1 ′ ″, R2 ′ ″, R3 ′ ″ Are combined into a single wire. Then, as in the first embodiment, the three wire rod portions (divided into three parts) are obtained to obtain one inspection frame 1 'as in this embodiment, rather than continuously using a wire bending apparatus. Parts) Using R1 ''',R2''', R3 '''can increase the production speed of wire parts (parts divided into three) R1''', R2 ''',R3''' In addition, there is an advantage that the shapes of the wire portions (parts divided into three) R1 ′ ″, R2 ′ ″, R3 ′ ″ are not easily distorted. That is, in this embodiment, after forming the three divided parts R1 ′ ″, R2 ′ ″, R3 ′ ″, the three members R1 ′ ″, R2 ′ ″, R3 ′ ″ are welded and connected. Thus, since one inspection frame 1 ′ is obtained, each component R1 ′ ″, R2 ′ ″, R3 ′ ″ is obtained from the first embodiment in which one inspection frame is continuously manufactured. The manufacturing speed and the stability of the shape can be increased, and the final shape correction work can be reduced. Incidentally, the welding point Z2 rather the welding point Z2 limited to part of the horizontal side 30, 30 'may be a position between leading from the second inclined portion 7 to the third inclined portion 13, also, The welding point Z2 may be set to 3 or more.
