Description

本発明は、中空構造物等からなる被締結部材に締結固定されるとともに、その端部に他のネジ部材を連結することができる、控え金具に関するものである。   The present invention relates to a metal brace that is fastened and fixed to a member to be fastened made of a hollow structure or the like and can be connected to another screw member at an end thereof.

中空構造物等に対して他の部材を固定する場合、ネジや釘等の一般的なファスナーでは、片側からの締結に限られることから中空構造物の厚みに応じた締結力しか得られない。このため、中空構造物の厚みが薄い場合には、ファスナーが抜け落ちる問題が生じる。   When other members are fixed to a hollow structure or the like, a general fastener such as a screw or a nail is limited to fastening from one side, so that only a fastening force corresponding to the thickness of the hollow structure can be obtained. For this reason, when the thickness of a hollow structure is thin, the problem that a fastener falls out arises.

そこで、これまでに中空構造物等に部材を固定する場合に用いられる、いわゆるブラインドボルトが提案されている。例えば、実開昭５１−１１９４５４号公報では、全ネジボルトの片端に、係止部材を一端が他端よりも重い状態で軸支して、前記係止部材が回転できるようにした中空構造用取り付けボルトが提案されている（特許文献１）。当該特許文献１によれば、前記係止部材は、中空構造物等の下孔に挿入されてその裏面側に配置されるとその重力差により直立姿勢となることができるとされている。そして、前記全ネジボルトにナットを締め付けることで前記中空構造物等を前記係止部材と前記ナットとにより挟持し、締結することができるとされている。また、前記ナットを緩めて前記全ネジボルトを１８０度回転させると、前記係止部材は前記全ネジボルトに沿った略平行状態になり、抜き取ることができるとされている。   In view of this, so-called blind bolts have been proposed that are used when a member is fixed to a hollow structure or the like. For example, in Japanese Utility Model Laid-Open No. 51-119454, a hollow structure mounting is provided in which a locking member is pivotally supported at one end of all screw bolts in a state where one end is heavier than the other end so that the locking member can rotate. A bolt has been proposed (Patent Document 1). According to Patent Document 1, when the locking member is inserted into a prepared hole of a hollow structure or the like and disposed on the back side thereof, it can be in an upright posture due to the difference in gravity. And it is supposed that the said hollow structure etc. can be clamped by the said locking member and the said nut, and can be fastened by fastening a nut to the said all screw volt | bolt. Further, when the nut is loosened and the full screw bolt is rotated 180 degrees, the locking member is in a substantially parallel state along the full screw bolt and can be removed.

実開昭５１−１１９４５４号公報Japanese Utility Model Publication No. 51-119454

しかしながら、特許文献１に記載された発明においては、中空構造物への締結時にナットとボルトとの摩擦力によって当該ボルトが供回りするという問題がある。中空構造物等の裏面側にある係止部材の姿勢は視認できないため、ボルトが供回りすると係止部材の姿勢が解らなくなってしまう。このため、供回りにより係止部材がその重力差で回転して直立姿勢にない状態で締結されても気づくことができない。直立姿勢ではない状態で締結されると前記係止部材が中空構造物の裏面にしっかりと当接できず、締結状態が弛み易くなり、ボルトが抜けてしまうおそれもある。このような供回りの防止方法として、ボルトを指で挟んで供回りを押さえながら締結することも考えられるが、ボルト径は細くて力が入り難く、円形であるために滑り易いことから、このような方法では完全に供回りを防ぐことができない。   However, in the invention described in Patent Document 1, there is a problem that the bolt is rotated by the frictional force between the nut and the bolt at the time of fastening to the hollow structure. Since the attitude of the locking member on the back side of the hollow structure or the like cannot be visually recognized, the attitude of the locking member cannot be understood when the bolt is rotated. For this reason, even if the locking member is rotated by the gravity difference due to the rotation and fastened without being in the upright posture, it cannot be noticed. If the fastening member is fastened in a state where it is not in an upright posture, the locking member cannot be firmly in contact with the back surface of the hollow structure, and the fastening state tends to be loosened and the bolt may come off. As a method for preventing such rotation, it is conceivable to tighten the bolt while holding the rotation with a finger, but the bolt diameter is thin and difficult to enter, and since it is circular, it is easy to slip. Such a method cannot completely prevent rotation.

また、直立姿勢ではない状態で締結されていると、ボルトを１８０度回転させても前記係止部材がボルトに沿った略平行状態に戻らず、抜き取ることができないという問題がある。つまり、係止部材がボルトに沿った略平行状態となる目印がないので、抜き取る際にはボルトを回しながら係止部材がボルトに沿った略平行状態となる位置を探り当てなければならない。   Further, if the bolt is fastened in a state where it is not in an upright posture, there is a problem that even if the bolt is rotated 180 degrees, the locking member does not return to a substantially parallel state along the bolt and cannot be removed. In other words, since there is no mark for the locking member to be in a substantially parallel state along the bolt, when extracting, the position where the locking member is in a substantially parallel state along the bolt must be found while turning the bolt.

さらに、締結時における荷重負荷は係止部材やこの係止部材を軸支する部分に集中するが、全ネジボルトであるために係止部材を軸支する部分の有効断面積が小さく、荷重耐力が弱いという問題がある。また、係止部材を設ける溝の切削端面が斜めに加工されており、加工コストが高いという問題もある。   Furthermore, the load load at the time of fastening is concentrated on the locking member and the portion that pivotally supports the locking member, but since it is a full screw bolt, the effective sectional area of the portion that pivotally supports the locking member is small, and the load bearing strength is low. There is a problem of being weak. Moreover, the cutting end face of the groove | channel which provides a locking member is processed diagonally, and there also exists a problem that processing cost is high.

本発明は、以上のような問題点を解決するためになされたものであって、中空構造物等の裏面側にあって見えない係止部材の姿勢を判別できるようにして、その供回りを防止するとともに、再利用のために取り外せる位置を容易に知ることができ、荷重耐力が強くかつ安価に製造することができる、控え金具を提供することを目的としている。   The present invention has been made to solve the above-described problems, and it is possible to determine the posture of a locking member that is not visible on the back side of a hollow structure or the like and An object of the present invention is to provide a metal brace that can be easily prevented from being removed and can be easily removed for reuse and can be manufactured at low cost with high load bearing strength.

By not providing a thread groove on the outer periphery, the effective sectional area is increased and the load bearing strength is increased. Is strong. The unthreaded portion 21 is formed in a bifurcated shape to support the plate-like locking member 3 in a state of being sandwiched from the side surface side. In the first embodiment, the base end portion that branches into a bifurcated shape is formed straight at right angles to the axial direction as shown in FIG. 2 in order to reduce processing costs. The screwless portion 21 is provided so that a support shaft 23 that rotatably supports the locking member 3 is orthogonal to the axis of the screwless portion 21.

係止部材３は、締結用ナット５とともに被締結部材９を挟持するため、当該被締結部材９の裏面側において直立姿勢となって前記裏面に係止されるものである。係止部材３は、被締結部材９の裏面側において重力差により直立姿勢となるように、前記ネジ無し部２１の支持軸２３に対し一端が他端よりも重い状態で回転自在に軸支されている。本第一実施形態における係止部材３は、図２に示すように、断面略長方形状の板材であってその長辺方向の一端部を傾斜状に形成されており、当該長辺方向の中央位置において前記支持軸２３により軸支されている。つまり、一端部を傾斜状に形成したことにより、その体積分、傾斜状の端部側を軽くしている。   Since the locking member 3 holds the fastened member 9 together with the fastening nut 5, the locking member 3 has an upright posture on the back side of the fastened member 9 and is locked to the back surface. The locking member 3 is pivotally supported so that one end is heavier than the other end with respect to the support shaft 23 of the screwless portion 21 so as to be in an upright posture due to a difference in gravity on the back side of the fastened member 9. ing. As shown in FIG. 2, the locking member 3 in the first embodiment is a plate material having a substantially rectangular cross section, and has one end portion in the long side direction formed in an inclined shape, and the center in the long side direction. It is supported by the support shaft 23 at a position. That is, by forming one end portion in an inclined shape, the volume fraction, the inclined end portion side is lightened.

また、係止部材３は、締結時における荷重耐力が当該係止部材３と、当該係止部材３を支持する支持軸２３と、この支持軸２３を設ける軸孔２４とにおいて均等にかかるようにして最大の荷重耐力が得られるように、図３および図４に示すように、ネジ無し部２１の直径寸法の約１／３となる厚さに形成されているとともに、前記支持軸２３および前記軸孔２４は、図１および図２に示すように、当該係止部材３の厚さと略同寸法の直径（ネジ無し分の直径寸法の約１／３）に形成されている。   Further, the locking member 3 is configured so that the load resistance at the time of fastening is evenly applied to the locking member 3, the support shaft 23 that supports the locking member 3, and the shaft hole 24 in which the support shaft 23 is provided. In order to obtain the maximum load bearing strength, as shown in FIGS. 3 and 4, the thickness is about ３ of the diameter dimension of the screwless portion 21, and the support shaft 23 and the As shown in FIGS. 1 and 2, the shaft hole 24 is formed to have a diameter that is approximately the same as the thickness of the locking member 3 (about 1/3 of the diameter of the screw-free portion).

ストッパー４は、係止部材３の重い方が上方側に向いた際に重力差により回転した当該係止部材３を前記ネジ無し部２１の軸線に沿った略平行状態に保持するためのものである。本第一実施形態におけるストッパー４は、図５に示すように、ネジ無し部２１の二股状に分岐する基端位置に形成されており、前記係止部材３の傾斜端部が当接して係止するようになっている。   The stopper 4 is for holding the locking member 3 rotated by a difference in gravity when the heavy side of the locking member 3 is directed upward, in a substantially parallel state along the axis of the screwless portion 21. is there. As shown in FIG. 5, the stopper 4 in the first embodiment is formed at the base end position where the screwless portion 21 branches into a bifurcated shape, and the inclined end portion of the locking member 3 abuts and engages. It comes to stop.

締結用ナット５は、雄ネジ部２２に螺合されて被締結部材９を締結するためのナットであり、ボルト本体２の雄ネジ部２２に螺合可能な雌ネジ孔５１を有している。また、締結用ナット５の係止部材３側には、取り付け忘れを防止するとともにナット部と供回りして被締結部材９に傷をつけるのを防止するため、図２に示すように、予め、ワッシャー５２が回転自在に備え付けられている。   The fastening nut 5 is a nut that is screwed to the male screw portion 22 to fasten the member 9 to be fastened, and has a female screw hole 51 that can be screwed to the male screw portion 22 of the bolt body 2. .

また、後端側の雌ネジ孔６２は、連結するネジ部材１０の雄ネジ径に応じて、前記雄ネジ部２２に螺合する雌ネジ孔６１の径と異なる径に形成されている。本第一実施形態では、図２に示すように、後端側の雌ネジ孔６２の径が雄ネジ部２２の径よりも大きく形成されている。   Further, the female screw hole 62 on the rear end side is formed with a diameter different from the diameter of the female screw hole 61 screwed into the male screw portion 22 in accordance with the male screw diameter of the screw member 10 to be connected. In the first embodiment, as shown in FIG. 2, the diameter of the female screw hole 62 on the rear end side is formed larger than the diameter of the male screw portion 22.

この連結用高ナット６は、その側面部の一部を側方向からカシメることにより、雄ネジ部２２に固定されている。連結用高ナット６は、図１および図２に示すように、細長平坦状マーカー部７のある側面位置をカシメることで、回転方向の滑りをより強固に防止している。   The connecting high nut 6 is fixed to the male screw portion 22 by caulking a part of the side surface portion from the side direction. As shown in FIGS. 1 and 2, the connecting high nut 6 more firmly prevents sliding in the rotational direction by caulking the side surface position where the elongated flat marker portion 7 is located.

なお、連結用高ナット６の後端側の雌ネジ孔６２は、雄ネジ部２２のネジ径と異なるものに限定されるものではなく、連結されるネジ部材１０のネジ径に応じて適宜選択されるものであり、図６に示すように、雄ネジ部２２のネジ径と同径の雌ネジ孔であってもよい。   The female screw hole 62 on the rear end side of the connecting high nut 6 is not limited to a screw diameter different from the screw diameter of the male screw portion 22 and is appropriately selected according to the screw diameter of the screw member 10 to be connected. As shown in FIG. 6, a female screw hole having the same diameter as the screw diameter of the male screw portion 22 may be used.

細長平坦状マーカー部７は、係止部材３がその重力差により回転する方向の目印になるとともに、締結時におけるボルト本体２と締結用ナット５との供回りを防止するために指やペンチで保持するかまたは図７に示すような供回り防止用専用工具１１を嵌め入れる部分であり、さらには上述のとおり連結用高ナット６のカシメ位置となるものである。   The elongated flat marker portion 7 serves as a mark in the direction in which the locking member 3 rotates due to the difference in gravitational force, and with a finger or pliers to prevent rotation of the bolt body 2 and the fastening nut 5 at the time of fastening. This is a part to be held or fitted with a dedicated tool 11 for preventing rotation as shown in FIG. 7, and further to the caulking position of the connecting high nut 6 as described above.

具体的には、細長平坦状マーカー部７は、前記ボルト本体２が水平でかつ前記係止部材３がその重力差により直立姿勢となる状態において、前記雄ネジ部２２の後端側外周の上部または下部のいずれか一方の位置に当該雄ネジ部２２の軸線に沿って形成されており、本第一実施形態では、図１に示すように、前記雄ネジ部２２の後端側外周の下部位置に形成されている。細長平坦状マーカー部７の長さは、特に限定されるものではないが、被締結部材９の厚さや連結用高ナット６の長さとの兼ね合いにより、締結時および取り外し時に作業者が視認できる程度の長さに形成されることが望ましい。   Specifically, the elongated flat marker portion 7 is an upper portion of the outer periphery on the rear end side of the male screw portion 22 in a state where the bolt body 2 is horizontal and the locking member 3 is in an upright posture due to the difference in gravity. Alternatively, it is formed along the axis of the male screw portion 22 at either one of the positions of the lower portion. In the first embodiment, as shown in FIG. Formed in position. The length of the elongated flat marker portion 7 is not particularly limited, but is such that the operator can visually recognize it at the time of fastening and removal due to the balance with the thickness of the fastened member 9 and the length of the connecting high nut 6. It is desirable that the length is formed.

また、細長平坦状マーカー部７の幅は、目印としての機能や、保持・カシメに最適な幅を考慮して適宜選択されるものではあり、図３および図４に示すように、雄ネジ部２２の直径に対して約１／４以上の幅を有していることが好ましく、雄ネジ部２２の強度を考慮すると雄ネジ部２２の直径に対して約１／２の幅を有していることがより好ましい。   The width of the elongated flat marker portion 7 is appropriately selected in consideration of the function as a mark and the optimum width for holding and caulking. As shown in FIGS. 3 and 4, the male screw portion Preferably, it has a width of about 1/4 or more with respect to the diameter of 22 and has a width of about 1/2 with respect to the diameter of the male screw portion 22 in consideration of the strength of the male screw portion 22. More preferably.

次に、本第一実施形態の控え金具１における各構成の作用について、当該控え金具１を用いて中空構造部材の角パイプ９２に壁材９３を締結し、さらに壁つなぎ等からなるネジ部材１０を連結する際の作業工程とともに説明する。   Next, with respect to the operation of each component in the retainer 1 of the first embodiment, the wall member 93 is fastened to the square pipe 92 of the hollow structural member using the retainer 1, and the screw member 10 made of a wall joint or the like is used. Will be described together with work steps when connecting the two.

まず、図８（ａ）に示すように、ボルト本体２のネジ無し部２１側が被締結部材９である角パイプ９２および壁材９３に形成された下孔９１に挿入される。このとき、係止部材３は、挿入時の邪魔にならないよう、ネジ無し部２１の軸線と平行状態として挿入される。例えば、細長平坦状マーカー部７を下方に向けた状態の場合には、係止部材３が重力差によって直立姿勢をとろうするため、当該係止部材３を指などで押さえながら挿入される。一方、細長平坦状マーカー部７を上方に向けた状態の場合には、係止部材３がストッパー４によってネジ無し部２１の軸線と平行状態に保持されるので、前記係止部材３を指で押さえる必要がなくそのまま容易に下孔９１に挿入できる。   First, as shown in FIG. 8A, the unthreaded portion 21 side of the bolt main body 2 is inserted into a square hole 92 that is a member to be fastened 9 and a lower hole 91 formed in a wall material 93. At this time, the locking member 3 is inserted in a state parallel to the axis of the screwless portion 21 so as not to obstruct the insertion. For example, in the state where the elongated flat marker portion 7 is directed downward, the locking member 3 takes an upright posture due to a difference in gravity, so that the locking member 3 is inserted while being pressed with a finger or the like. On the other hand, when the elongated flat marker portion 7 is directed upward, the locking member 3 is held in parallel with the axis of the screwless portion 21 by the stopper 4, so that the locking member 3 can be held with a finger. It is not necessary to hold down and can be easily inserted into the prepared hole 91 as it is.

図８（ｂ）に示すように、係止部材３が被締結部材９の裏面側に配置されるまで挿入されると、細長平坦状マーカー部７が下方になるよう確認し、必要に応じてボルト本体２をその方向に回転させる。これにより係止部材３は、被締結部材９の裏面において支持軸２３を支点として両端の重力差により回転し直立姿勢となる。   As shown in FIG. 8 (b), when the locking member 3 is inserted until it is arranged on the back side of the fastened member 9, confirm that the elongated flat marker portion 7 is downward, and if necessary The bolt body 2 is rotated in that direction. As a result, the locking member 3 rotates on the back surface of the fastened member 9 with the support shaft 23 as a fulcrum due to the difference in gravity between both ends, and assumes an upright posture.

ここで、細長平坦状マーカー部７は、係止部材３が直立姿勢となる方向を示しているため、被締結部材９の表面側から見えない前記係止部材３の姿勢を判別しながら作業することができ、当該係止部材３を確実に直立姿勢に保持することができる。   Here, since the elongated flat marker portion 7 indicates the direction in which the locking member 3 is in the upright posture, the elongated flat marker portion 7 is operated while determining the posture of the locking member 3 that is not visible from the surface side of the fastened member 9. The locking member 3 can be reliably held in the upright posture.

次に、図８（ｃ）に示すように、レンチ等の工具を用いて締結用ナット５を被締結部材９に締結させる。締結用ナット５は、被締結部材９の裏面側で直立姿勢となっている係止部材３とともに被締結部材９を挟持することで当該被締結部材９を締結する。本第一実施形態では、締結用ナット５にワッシャー５２を予め取り付けているため、ワッシャー５２の取り付け忘れが防止される。また、当該ワッシャー５２は、締結用ナット５に対して回転自在に設けられているため、ナット部分のみを回転させることができ、ワッシャー５２がナット部分と供回りして壁材９３等を傷つけるのを防止することができる。   Next, as shown in FIG. 8C, the fastening nut 5 is fastened to the fastened member 9 by using a tool such as a wrench. The nut 5 for fastening fastens the said to-be-fastened member 9 by pinching the to-be-fastened member 9 with the latching member 3 which is the upright posture in the back surface side of the to-be-fastened member 9. In the first embodiment, since the washer 52 is attached to the fastening nut 5 in advance, forgetting to attach the washer 52 is prevented. Further, since the washer 52 is provided so as to be rotatable with respect to the fastening nut 5, only the nut portion can be rotated, and the washer 52 rotates with the nut portion and damages the wall material 93 and the like. Can be prevented.

また、締結時にボルト本体２が締結用ナット５と供回りする場合は、指やペンチで細長平坦状マーカー部７を保持するかまたは図７（ｂ）に示すような供回り防止用専用工具１１を細長平坦状マーカー部７の側方から嵌め入れてそれを保持することで供回りが防止される。細長平坦状マーカー部７は、平坦に形成されているため掴みやすく、供回りを確実に防止することができる。   Further, when the bolt body 2 is rotated around the fastening nut 5 at the time of fastening, the elongated flat marker portion 7 is held with a finger or pliers or a dedicated tool 11 for preventing rotation as shown in FIG. Is fitted from the side of the elongated flat marker portion 7 and is held to prevent rotation. Since the elongated flat marker portion 7 is formed flat, it can be easily grasped and can be reliably prevented.

締結用ナット５の締結が完了すると、連結用高ナット６に壁つなぎ等のネジ部材１０を連結する。連結用高ナット６は、後端部に雌ネジ孔６２が形成されているため、これに合う雄ネジを有するネジ部材１０を連結することができる。   When the fastening of the fastening nut 5 is completed, the screw member 10 such as a wall joint is connected to the connecting high nut 6. Since the internal thread hole 62 is formed in the rear end portion of the connection high nut 6, the screw member 10 having an external thread suitable for the connection can be connected.

以上により、本第一実施形態の控え金具１は、図８（ｄ）に示すように、被締結部材９を締結し、さらにネジ部材１０を連結することができる。このとき、ネジ無し部２１の有効断面積を大きく、かつ締結時における荷重耐力を係止部材３、支持軸２３および軸孔２４でそれぞれ均等にしているため荷重耐力は強い。   As described above, the retainer 1 according to the first embodiment can fasten the fastened member 9 and further connect the screw member 10 as shown in FIG. At this time, since the effective sectional area of the screwless portion 21 is large and the load bearing strength at the time of fastening is equalized by the locking member 3, the support shaft 23, and the shaft hole 24, the load bearing strength is strong.

次に、被締結部材９に締結された本第一実施形態の控え金具１の取り外し方について説明する。   Next, how to remove the metal brace 1 of the first embodiment fastened to the fastened member 9 will be described.

まず、図９（ａ）に示すように、締結用ナット５を緩めて、下孔９１に対してボルト本体２が自由に軸回転できるようにする。   First, as shown in FIG. 9A, the fastening nut 5 is loosened so that the bolt body 2 can freely rotate about the lower hole 91.

次に、図９（ｂ）に示すように、ボルト本体２を、細長平坦状マーカー部７が下方側を向いている状態から上方側に向くように約１８０度軸回転する。細長平坦状マーカー部７により、上述のとおり被締結部材９の裏面側にある係止部材３の姿勢を判別できるので、表面側から係止部材３の上下方向を確実に変えられる。この状態における係止部材３は、上側が重くなるためその重力差により回転し、ストッパー４が回転する係止部材３の端部を係止して当該係止部材３をネジ無し部２１の軸線に沿った略平行状態の姿勢に保持する。   Next, as shown in FIG. 9B, the bolt body 2 is rotated about 180 degrees so that the elongated flat marker portion 7 is directed upward from the state in which the elongated flat marker portion 7 is directed downward. Since the elongated flat marker portion 7 can determine the posture of the locking member 3 on the back side of the fastened member 9 as described above, the vertical direction of the locking member 3 can be reliably changed from the front surface side. Since the locking member 3 in this state is heavy on the upper side, the locking member 3 rotates due to the difference in gravity, and the stopper 4 rotates to lock the end of the locking member 3 so that the locking member 3 is connected to the axis of the screwless portion 21. Is held in a substantially parallel posture.

これにより、図９（ｃ）に示すように、係止部材３が被締結部材９の裏面側に係止されない状態となるため、控え金具１を下孔９１から引き抜くように取り外すことができる。引き抜かれた控え金具１は、繰り返し何度でも使用することができる。   As a result, as shown in FIG. 9 (c), the locking member 3 is not locked to the back side of the fastened member 9, so that the retainer 1 can be removed so as to be pulled out from the lower hole 91. The pulled-out holding metal fitting 1 can be used over and over again.

以上のような本第一実施形態の控え金具１によれば、以下の効果を奏することができる。
１．被締結部材９の裏面側に配置されて直接視認することのできない係止部材３の姿勢が、表面側に配置される細長平坦状マーカー部７の位置により確実に把握できるため、控え金具１の締結および取り外しを容易に行うことができる。
２．細長平坦状マーカー部７が所定の長さと幅を有する平坦状に形成されているため、指やペンチ等で保持し易く、または供回り防止用専用工具１１を嵌め合わせて回転を抑えることができるため、締結用ナット５との摩擦により生じるボルト本体２の供回りを防止することができる。
３．細長平坦状マーカー部７は、塗料などによるマーカーと異なり使用を繰り返すことにより剥がれ落ちることは無いため、半永久的に繰り返し使用することができる。
４．細長平坦状マーカー部７は、その位置で連結用高ナット６をカシメられることにより、当該連結用高ナット６を回転方向の滑りを防止した状態で固定することができる。
５．雄ネジ部２２の後端に、連結する他のネジ部材１０の雄ネジ径に応じた連結用高ナット６を固定することにより、雄ネジ部２２と同径、異径を問わず、様々なネジ部材１０を連結することができる。
６．ネジ無し部２１および係止部材３等の荷重耐力が強いため、重たいネジ部材１０を連結することができる。 According to the retainer 1 of the first embodiment as described above, the following effects can be achieved.
1. Since the posture of the locking member 3 that is arranged on the back surface side of the fastened member 9 and cannot be directly recognized can be surely grasped by the position of the elongated flat marker portion 7 arranged on the front surface side, Fastening and removal can be easily performed.
2. Since the elongated flat marker portion 7 is formed in a flat shape having a predetermined length and width, it can be easily held with a finger, pliers or the like, or the rotation prevention can be suppressed by fitting the dedicated tool 11 for preventing rotation. Therefore, it is possible to prevent the bolt body 2 from rotating due to friction with the fastening nut 5.
3. Since the elongated flat marker portion 7 does not peel off by repeated use unlike a marker made of paint or the like, it can be used repeatedly semipermanently.
4). The elongated flat marker portion 7 can be fixed in a state in which the connecting high nut 6 is prevented from slipping in the rotational direction by caulking the connecting high nut 6 at that position.
5. By fixing the connecting high nut 6 according to the male screw diameter of the other screw member 10 to be connected to the rear end of the male screw part 22, various kinds of diameters can be used regardless of whether the male screw part 22 has the same diameter or different diameter. The screw member 10 can be connected.
6). Since the load resistance of the unthreaded portion 21 and the locking member 3 is strong, the heavy screw member 10 can be connected.

次に、本発明に係る控え金具の第二実施形態について図１０および図１１を用いて説明する。なお、本第二実施形態の控え金具１のうち、上述した第一実施形態の構成と同等または相当する構成については、再度の説明を省略する。   Next, a second embodiment of the metal fitting according to the present invention will be described with reference to FIGS. 10 and 11. In addition, about the structure 1 equivalent to the structure of 1st embodiment mentioned above among the metal fittings 1 of this 2nd embodiment, description for the second time is abbreviate | omitted.
