Description

本発明は、既設の手摺りや防護柵などの構造体に、規制チェーンやガードワイヤーなどの取付対象を後付けするのに好適な取付金具に関し、とくに構造体に外嵌状に固定される取付金具に関する。 The present invention relates to a mounting bracket suitable for retrofitting a mounting target such as a regulation chain or a guard wire to an existing structure such as a handrail or a guard fence, and particularly to a mounting bracket that is externally fixed to the structure. ..

例えば通路用の間隙が設けられた既設の手摺りに、該間隙の通行を規制する規制チェーン（取付対象）を後付けするためには、規制チェーンの端部を支柱（構造体）に連結する必要がある。しかし、既設の支柱に電動工具などを使用して孔開け加工を施すことは困難であり、また、支柱がパイプなどの中空体である場合、支柱に孔を開設すると支柱内に水分が侵入し腐食の要因となるおそれがある。そこで、支柱に孔開けを施さず規制チェーンを連結するためには、支柱に外嵌状に固定される取付金具が有用である。 For example, in order to retrofit an existing handrail provided with a gap for a passage with a regulation chain (attachment target) that regulates the passage of the gap, it is necessary to connect the end of the regulation chain to a support (structure). There is. However, it is difficult to make holes in the existing columns using an electric tool or the like, and if the columns are hollow bodies such as pipes, if holes are made in the columns, moisture will enter the columns. It may cause corrosion. Therefore, in order to connect the regulation chain without making a hole in the support column, a mounting bracket fixed to the support column in an externally fitted shape is useful.

上記固定形態の取付金具は、例えば特許文献１に公知である。特許文献１の取付金具では、半円板状の基端部と直線板状の先端部とで構成される一対の取付金具と、両取付金具の基端部の一端どうしを接続するヒンジとで金具本体が構成されている。ヒンジにはコイルスプリングが設けられており、該コイルスプリングで一対の取付金具が閉じ姿勢に付勢されている。各取付金具の先端部にはそれぞれ貫通孔が設けられている。 The mounting bracket in the fixed form is known in Patent Document 1, for example. In the mounting bracket of Patent Document 1, a pair of mounting brackets composed of a semicircular plate-shaped base end portion and a straight plate-shaped tip portion, and a hinge connecting one ends of the base end portions of both mounting brackets are used. The metal fitting body is configured. A coil spring is provided on the hinge, and the coil spring urges a pair of mounting brackets in a closed posture. A through hole is provided at the tip of each mounting bracket.

特開２００７−２２５１０２号公報JP-A-2007-225102

特許文献１の取付金具は、コイルスプリングの付勢力に抗して一対の取付金具を拡開姿勢にし、両基端部間に配管（構造体）が位置する状態でコイルスプリングの付勢力で取付金具を閉じ姿勢とすることにより、配管に取付金具を固定できる。これにより、配管に孔開けを施すことなく取付対象を連結するための孔を容易に設けることができる。しかし、取付金具の基端部に形成されているのは貫通孔であるため、カラビナ等に代表される開閉ゲートを備える取付対象であれば連結できるが、取付対象が鎖の単位コマ等の無端環状のものであると取付金具に直接連結することができず、連結可能な取付対象が限られる点で改善の余地がある。 The mounting bracket of Patent Document 1 is mounted by the urging force of the coil spring in a state where the pair of mounting brackets are in the expanded posture against the urging force of the coil spring and the pipe (structure) is located between the two base ends. The mounting bracket can be fixed to the pipe by closing the bracket. As a result, it is possible to easily provide a hole for connecting the attachment target without making a hole in the pipe. However, since it is a through hole formed at the base end of the mounting bracket, any mounting target having an opening / closing gate represented by a carabiner or the like can be connected, but the mounting target is an endless chain unit piece or the like. If it is an annular type, it cannot be directly connected to the mounting bracket, and there is room for improvement in that the mounting targets that can be connected are limited.

本発明は、構造体に外嵌状に固定される取付金具において、構造物に簡便に固定でき、しかも無端環状の取付対象であっても直接連結できるようにすることを目的とする。 An object of the present invention is to provide a mounting bracket that is externally fitted to a structure so that it can be easily fixed to the structure and can be directly connected even if it is an endless annular mounting target.

本発明の取付金具１は、構造体２に外嵌装着される抱持体４と、構造体２に外嵌装着された抱持体４に着脱可能に装着される連結体５とを備えている。抱持体４は、可撓性を有し構造体２に巻回される有端環状の抱持壁８と、抱持壁８の環端部からそれぞれ構造体２から離れる向きに連設される一対の締付壁９とを備える。締付壁９には、同壁９を厚み方向に貫通する第１通孔１６と、該第１通孔１６の周縁から締付壁９の周縁にわたって形成される第１スリット１７とがそれぞれ設けられている。連結体５は、隙間を介して対向配置される一対の挟持壁２１と、両挟持壁２１を橋絡する橋絡壁２２とを備えている。抱持体４に、一対の挟持壁２１で一対の締付壁９を挟み込むように連結体５を装着することにより、構造体２と抱持体４とが圧嵌係合され、さらに締付壁９と挟持壁２１とで取付対象３の連結部２８が形成されるように構成されている。そして、抱持体４に連結体５が装着される過程で、締付壁９に形成された第１スリット１７に連結体５の挟持壁２１が重畳して、連結部２８に第１通孔１６を含んで構成される貫通状の連結孔２９が形成されるようになっていることを特徴とする。 The mounting bracket 1 of the present invention includes a holding body 4 that is externally mounted on the structure 2 and a connecting body 5 that is detachably mounted on the holding body 4 that is externally mounted on the structure 2. There is. The hugging body 4 is connected to a hugging wall 8 having an end ring that is flexible and wound around the structure 2 and a hugging wall 8 that is connected to each other in a direction away from the structure 2 from the ring end portion of the hugging wall 8. A pair of tightening walls 9 are provided. The tightening wall 9 is provided with a first through hole 16 penetrating the wall 9 in the thickness direction and a first slit 17 formed from the peripheral edge of the first through hole 16 to the peripheral edge of the tightening wall 9. Has been done. The connecting body 5 includes a pair of holding walls 21 that are arranged so as to face each other through a gap, and a bridge wall 22 that bridges both holding walls 21. By attaching the connecting body 5 to the holding body 4 so that the pair of tightening walls 9 are sandwiched between the pair of holding walls 21, the structure 2 and the holding body 4 are press-fitted and engaged with each other, and further tightened. The wall 9 and the holding wall 21 are configured to form a connecting portion 28 of the mounting target 3. Then, in the process of mounting the connecting body 5 on the holding body 4, the holding wall 21 of the connecting body 5 is superimposed on the first slit 17 formed in the tightening wall 9, and the first through hole is formed in the connecting portion 28. It is characterized in that a through-shaped connecting hole 29 including 16 is formed.

連結体５の各挟持壁２１には、厚み方向に貫通する第２通孔２３と、該第２通孔２３の周縁から締付壁９の周縁にわたって形成される第２スリット２４とがそれぞれ設けられている。抱持体４に対する連結体５の装着姿勢を変更することにより、連結部２８の形態が、第１スリット１７と挟持壁２１、および第１通孔１６と第２通孔２３とが重畳して、連結部２８に貫通状の連結孔２９が形成される貫通孔形態と、第１スリット１７と第２スリット２４、および第１通孔１６と第２通孔２３とが重畳して、連結部２８に切欠き状のフック溝３０が形成されるフック形態とに、選択的に切換え可能に構成されている。 Each holding wall 21 of the connecting body 5 is provided with a second through hole 23 penetrating in the thickness direction and a second slit 24 formed from the peripheral edge of the second through hole 23 to the peripheral edge of the tightening wall 9. Has been done. By changing the mounting posture of the connecting body 5 with respect to the holding body 4, the form of the connecting portion 28 overlaps with the first slit 17, the holding wall 21, and the first through hole 16 and the second through hole 23. , The through-hole form in which the through-shaped connecting hole 29 is formed in the connecting portion 28, the first slit 17 and the second slit 24, and the first through hole 16 and the second through hole 23 are overlapped with each other to form the connecting portion. It is configured to be selectively switchable to a hook form in which a notch-shaped hook groove 30 is formed in 28.

構造体２の断面は矩形状に構成されている。構造体２の断面中心から構造体２に外嵌装着された抱持体４の締付壁９を見た方向を前方向と規定するとき、抱持壁８は、後壁１０と、後壁１０の各端部にそれぞれ連設される左右壁１１・１２と、該左右壁１１・１２の端部にそれぞれ連設される一対の前壁１３・１３とを備え、左右壁１１・１２の少なくとも一方が内凹み湾曲状に形成されている。抱持体４に連結体５を装着したとき、内凹み湾曲状に形成された左右壁１１・１２が、その曲率が小さくなるように弾性変形した状態で構造体２と抱持壁８とが圧嵌係合されるようになっている。 The cross section of the structure 2 is formed in a rectangular shape. When the direction in which the tightening wall 9 of the holding body 4 externally fitted to the structure 2 is viewed from the center of the cross section of the structure 2 is defined as the front direction, the holding wall 8 is the rear wall 10 and the rear wall. The left and right walls 11 and 12, which are connected to each end of the left and right walls 11 and 12, and a pair of front walls 13 and 13 which are connected to the ends of the left and right walls 11 and 12, respectively, are provided. At least one is formed in an inwardly concave curved shape. When the connecting body 5 is attached to the holding body 4, the structure 2 and the holding wall 8 are in a state where the left and right walls 11 and 12 formed in an inwardly concave curved shape are elastically deformed so that the curvature becomes smaller. It is designed to be press-fitted and engaged.

構造体２の断面は円状に構成されている。構造体２の断面中心から構造体２に外嵌装着された抱持体４の締付壁９を見た方向を前方向と規定するとき、抱持壁８は、前方に切欠き部３４を有する円環状に形成され、抱持壁８の左円環壁３５および右円環壁３６の少なくとも一方が、構造体２の外周面の曲率よりも小さい曲率の緩曲円環状に形成されている。抱持体４に連結体５を装着したとき、緩曲円環状に形成された左右の円環壁３５・３６が、構造体２の外周面に沿うように弾性変形した状態で構造体２と抱持壁８とが圧嵌係合されるようになっている。 The cross section of the structure 2 is formed in a circular shape. When the direction in which the tightening wall 9 of the holding body 4 externally fitted to the structure 2 is viewed from the center of the cross section of the structure 2 is defined as the forward direction, the holding wall 8 has a notch 34 in front. It is formed in an annulus having an annulus, and at least one of the left annulus wall 35 and the right annulus wall 36 of the holding wall 8 is formed in a gently curved annulus having a curvature smaller than the curvature of the outer peripheral surface of the structure 2. .. When the connecting body 5 is attached to the holding body 4, the left and right annular walls 35 and 36 formed in a gently curved annulus are elastically deformed along the outer peripheral surface of the structure 2 with the structure 2. The holding wall 8 is press-fitted and engaged.

締付壁９に保持突起１８が形成され、挟持壁２１に保持突起１８と係合する係合孔２５が形成されている。 A holding protrusion 18 is formed on the tightening wall 9, and an engaging hole 25 that engages with the holding protrusion 18 is formed on the holding wall 21.

本発明の取付金具１においては、抱持体４に連結体５を装着することにより、構造体２と抱持壁８とが圧嵌係合されるように構成した。これによれば、抱持体４に連結体５を装着するだけの簡単な動作で、構造体２に取付金具１を固定することができる。また、抱持体４に連結体５を装着したとき、締付壁９に形成された第１スリット１７に連結体５の挟持壁２１が重畳して、連結部２８に第１通孔１６を含んで構成される貫通状の連結孔２９が形成されるように構成した。これによれば、無端環状の取付対象３の一部を第１スリット１７を介して第１通孔１６に位置させ、この状態で抱持体４に連結体５を装着することにより、連結部２８の連結孔２９に無端環状の取付対象３を連結することができる。以上のように本発明によれば、抱持体４への連結体５の装着動作によって、構造物２に簡便に固定でき、さらに無端環状の取付対象３を直接連結することができる取付金具１を得ることができる。 In the mounting bracket 1 of the present invention, the structure 2 and the holding wall 8 are press-fitted and engaged with each other by mounting the connecting body 5 on the holding body 4. According to this, the mounting bracket 1 can be fixed to the structure 2 by a simple operation of attaching the connecting body 5 to the holding body 4. Further, when the connecting body 5 is attached to the holding body 4, the holding wall 21 of the connecting body 5 is superimposed on the first slit 17 formed in the tightening wall 9, and the first through hole 16 is provided in the connecting portion 28. It was configured so that a through-shaped connecting hole 29 including the portion was formed. According to this, a part of the endless annular mounting target 3 is positioned in the first through hole 16 via the first slit 17, and in this state, the connecting body 5 is mounted on the holding body 4, thereby connecting the connecting portion. An endless annular mounting target 3 can be connected to the connecting hole 29 of 28. As described above, according to the present invention, the mounting bracket 1 can be easily fixed to the structure 2 by the mounting operation of the connecting body 5 to the holding body 4, and further, the endless annular mounting target 3 can be directly connected. Can be obtained.

抱持体４に対する連結体５の装着姿勢を変更することにより、連結部２８の形態を、連結部２８に貫通状の連結孔２９が形成される貫通孔形態と、連結部２８に切欠き状のフック溝３０が形成されるフック形態とに、選択的に切換え可能に構成した。これによれば、一組の抱持体４と連結体５とからなる取付金具１で、連結部２８を貫通孔形態とフック形態のいずれかに切換えることができるので、取付金具１の利便性を向上し、また各形態毎に取付金具１を用意するコストを削減することができる。 By changing the mounting posture of the connecting body 5 with respect to the holding body 4, the form of the connecting portion 28 is changed into a through-hole form in which a through-shaped connecting hole 29 is formed in the connecting portion 28 and a notch shape in the connecting portion 28. It is configured to be selectively switchable to the hook form in which the hook groove 30 of the above is formed. According to this, the connecting portion 28 can be switched between the through hole form and the hook form by the mounting bracket 1 composed of a set of the holding body 4 and the connecting body 5, so that the convenience of the mounting bracket 1 is achieved. It is possible to improve and reduce the cost of preparing the mounting bracket 1 for each form.

断面矩形状の構造体２に抱持体４を外嵌装着し、さらに外嵌装着した抱持体４に連結体５を装着したとき、内凹み湾曲状に形成された左右壁１１・１２が、その曲率が小さくなるように弾性変形した状態で構造体２と抱持壁８とが圧嵌係合されるようにした。これによれば、内凹み湾曲状に形成された左右壁１１・１２の弾性復元力で抱持壁８と構造体２との間の摩擦力を増大させることができるので、構造体２に対して取付金具１をより強固に固定することができる。 When the holding body 4 is externally fitted to the structure 2 having a rectangular cross section and the connecting body 5 is mounted to the externally fitted holding body 4, the left and right walls 11 and 12 formed in an inwardly concave curved shape are formed. The structure 2 and the holding wall 8 are press-fitted and engaged with each other in a state of being elastically deformed so that the curvature is reduced. According to this, the frictional force between the holding wall 8 and the structure 2 can be increased by the elastic restoring force of the left and right walls 11 and 12 formed in the curved shape of the inner recess, so that the frictional force between the holding wall 8 and the structure 2 can be increased with respect to the structure 2. The mounting bracket 1 can be fixed more firmly.

断面円状の構造体２に抱持体４を外嵌装着し、さらに外嵌装着した抱持体４に連結体５を装着したとき、緩曲円環状に形成された左右の円環壁３５・３６が、構造体２の外周面に沿うように弾性変形した状態で構造体２と抱持壁８とが圧嵌係合されるようにした。これによれば、上記と同様に、緩曲円環状に形成された左右の円環壁３５・３６の弾性復元力で抱持壁８と構造体２との間の摩擦力を増大させることができるので、構造体２に対して取付金具１をより強固に固定することができる。 When the holding body 4 is externally fitted to the structure 2 having a circular cross section and the connecting body 5 is mounted to the externally fitted holding body 4, the left and right annular walls 35 formed in a gently curved annular shape. The structure 2 and the holding wall 8 are press-fitted and engaged with the 36 in a state of being elastically deformed along the outer peripheral surface of the structure 2. According to this, similarly to the above, the frictional force between the holding wall 8 and the structure 2 can be increased by the elastic restoring force of the left and right annular walls 35 and 36 formed in a gently curved annulus. Therefore, the mounting bracket 1 can be more firmly fixed to the structure 2.

締付壁９に保持突起１８が形成され、挟持壁２１に保持突起１８と係合する係合孔２５が形成されていると、連結体５が抱持体４から不用意に分離されることを回避して、構造体２から取付金具１が脱落するのを防止できる。また、保持突起１８が係合孔２５に嵌り込む際の節度感で、抱持体４の適正位置に連結体５が装着されたことを目視することなく認識することができる。 If the holding protrusion 18 is formed on the tightening wall 9 and the engaging hole 25 that engages with the holding protrusion 18 is formed on the holding wall 21, the connecting body 5 is carelessly separated from the holding body 4. Can be avoided and the mounting bracket 1 can be prevented from falling off from the structure 2. Further, it is possible to recognize that the connecting body 5 is mounted at an appropriate position of the holding body 4 without visually recognizing the moderation when the holding protrusion 18 is fitted into the engaging hole 25.

Further, the gap dimension W1 of the narrowest portion between the left and right walls 11 and 12 is set to be smaller than the left and right width dimension W2 of the structure 2 (see FIG. 9). FIG. 6 shows the shape of the holding body 4 as viewed from the front, the back, the plane, the bottom, and the right side.

図２に示すように連結体５は、構造体２に外嵌装着された抱持体４に装着されるものであり、隙間を介して対向配置される一対の挟持壁２１と、両挟持壁２１の前縁どうしを橋絡する半円弧状の橋絡壁２２とを備えている。各挟持壁２１の中央には、同壁２２を厚み方向に貫通する第２通孔２３と、第２通孔２３の下周縁と挟持壁２１の下周縁とに跨る第２スリット２４とがそれぞれ形成されている。これら第２通孔２３および第２スリット２４により、各挟持壁２１には下周縁で開口する切欠きが形成される。第２通孔２３の直径寸法は、第２スリット２４の幅寸法より僅かに大きく形成されている。各挟持壁２１の後端寄りには、先の保持突起１８が係合する係合孔２５が、同突起１８に対応する位置に開設されている。挟持壁２１の上下寸法Ｈ２は、締付壁９の上下寸法Ｈ１よりも大きく設定されている。 As shown in FIG. 2, the connecting body 5 is attached to the holding body 4 which is externally fitted to the structure 2, and has a pair of holding walls 21 which are arranged to face each other through a gap and both holding walls. It is provided with a semi-arc-shaped bridge wall 22 that bridges the leading edges of 21. At the center of each holding wall 21, a second through hole 23 penetrating the wall 22 in the thickness direction and a second slit 24 straddling the lower peripheral edge of the second through hole 23 and the lower peripheral edge of the holding wall 21 are respectively. It is formed. The second through hole 23 and the second slit 24 form a notch that opens at the lower peripheral edge of each holding wall 21. The diameter dimension of the second through hole 23 is formed to be slightly larger than the width dimension of the second slit 24. An engaging hole 25 with which the previous holding protrusion 18 is engaged is provided at a position corresponding to the holding protrusion 18 near the rear end of each holding wall 21. The vertical dimension H2 of the holding wall 21 is set to be larger than the vertical dimension H1 of the tightening wall 9.

本実施例の連結体５は先の抱持体４と同様にばね鋼からなる板材を素材として構成されており、所定形状に打ち抜き加工を施したのち、曲げ加工を施して形成される。一対の挟持壁２１は略平行に配置されており、一対の挟持壁２１の内法寸法は、自由状態における抱持体４の一対の締付壁９の最大外法寸法よりも小さく、かつ一対の締付壁９の合計厚み寸法よりも大きく設定されている。図７は連結体５を正面、背面、平面、底面、および右側面から見た形状を示している。連結体５は、その一対の挟持壁２１が一対の締付壁９を挟持するように抱持体４に対して装着される。抱持体４に連結体５が装着されることにより、締付壁９と挟持壁２１とで取付対象３の連結部２８が形成される。 Like the holding body 4, the connecting body 5 of this embodiment is made of a plate material made of spring steel, and is formed by punching a predetermined shape and then bending the connecting body 5. The pair of holding walls 21 are arranged substantially in parallel, and the inner dimension of the pair of holding walls 21 is smaller than the maximum outer dimension of the pair of tightening walls 9 of the holding body 4 in the free state, and the pair It is set to be larger than the total thickness dimension of the tightening wall 9 of. FIG. 7 shows the shape of the connecting body 5 as viewed from the front surface, the back surface, the flat surface, the bottom surface, and the right side surface. The connecting body 5 is attached to the holding body 4 so that the pair of holding walls 21 sandwich the pair of tightening walls 9. By mounting the connecting body 5 on the holding body 4, the connecting portion 28 of the mounting target 3 is formed by the tightening wall 9 and the holding wall 21.

連結体５は、第２スリット２４の開放部分が下向きに指向する状態（正姿勢）、または第２スリット２４の開放部分が上向きに指向する状態（逆姿勢）のいずれかの姿勢で抱持体４に装着できる。前者の状態で抱持体４に対して連結体５を装着すると、図３（ａ）に示すように、第１スリット１７と挟持壁２１、および第１通孔１６と第２通孔２３とが重畳して、連結部２８に第１通孔１６と第２通孔２３とで構成される左右貫通状の連結孔２９が形成される貫通孔形態とすることができる。また、後者の状態で抱持体４に対して連結体５を装着すると、図３（ｂ）に示すように、第１スリット１７と第２スリット２４、および第１通孔１６と第２通孔２３とが重畳して、連結部２８に切欠き状のフック溝３０が形成されるフック形態とすることができる。このように、抱持体４に対する連結体５の装着姿勢を変更することで、連結部２８の形態が貫通孔形態またはフック形態に選択的に切換え可能に構成されている。抱持体４に装着された連結体５は、保持突起１８と係合孔２５とが係合されることで分離が阻止され、これにより抱持体４と連結体５とは一体化される。図８は連結部２８を貫通孔形態とした状態の取付金具１を正面、背面、平面、底面、および右側面から見た形状を示している。 The connecting body 5 is held in either a posture in which the open portion of the second slit 24 is oriented downward (normal posture) or a state in which the open portion of the second slit 24 is oriented upward (reverse posture). Can be attached to 4. When the connecting body 5 is attached to the holding body 4 in the former state, as shown in FIG. 3A, the first slit 17, the holding wall 21, and the first through hole 16 and the second through hole 23 become Can be formed in the form of a through hole in which the left and right through-shaped connecting holes 29 composed of the first through hole 16 and the second through hole 23 are formed in the connecting portion 28 by superimposing the above. Further, when the connecting body 5 is attached to the holding body 4 in the latter state, as shown in FIG. 3 (b), the first slit 17 and the second slit 24, and the first through hole 16 and the second through hole 16 and the second through. It is possible to form a hook in which the holes 23 are overlapped with each other to form a notch-shaped hook groove 30 in the connecting portion 28. In this way, by changing the mounting posture of the connecting body 5 with respect to the holding body 4, the form of the connecting portion 28 can be selectively switched to the through hole form or the hook form. The connecting body 5 attached to the holding body 4 is prevented from being separated by engaging the holding protrusion 18 and the engaging hole 25, whereby the holding body 4 and the connecting body 5 are integrated. .. FIG. 8 shows the shape of the mounting bracket 1 in the state where the connecting portion 28 is in the form of a through hole as viewed from the front surface, the back surface, the flat surface, the bottom surface, and the right side surface.

図４および図５に示すように、連結体５が装着された抱持体４の前壁１３および後壁１０は、それぞれ構造体２の前面および後面に密着しており、取付金具１の前後移動は規制されている。また、抱持体４は、その前側が自由状態のときに比べて左右方向に収縮された状態であり、抱持体４の拡開変形は連結体５により規制されている。先に説明したように、自由状態における抱持体４の左右壁１１・１２間の間隙寸法Ｗ１は、構造体２の左右幅寸法Ｗ２よりも小さく設定されているので、湾曲壁からなる左右壁１１・１２は、図５に示す二点鎖線の形状（自由状態の左右壁１１・１２の形状）からその曲率が小さくなる方向へ弾性変形されている。これにより、抱持壁８の左右壁１１・１２はその弾性復元力で構造体２を挟持している。また、左右壁１１・１２の弾性復元力により、抱持体４の締付壁９は、連結体５の挟持壁２１に押付けられており、従って、保持突起１８と係合孔２５との係合状態がより解除されにくくなり、両者４・５を強固に一体化できる。 As shown in FIGS. 4 and 5, the front wall 13 and the rear wall 10 of the holding body 4 to which the connecting body 5 is mounted are in close contact with the front surface and the rear surface of the structure 2, respectively, and are in close contact with the front and rear surfaces of the mounting bracket 1. Movement is restricted. Further, the holding body 4 is in a state of being contracted in the left-right direction as compared with the case where the front side thereof is in a free state, and the expansion deformation of the holding body 4 is regulated by the connecting body 5. As described above, the gap dimension W1 between the left and right walls 11 and 12 of the holding body 4 in the free state is set to be smaller than the left and right width dimension W2 of the structure 2, so that the left and right walls composed of curved walls. 11 and 12 are elastically deformed from the shape of the alternate long and short dash line shown in FIG. 5 (the shape of the left and right walls 11 and 12 in the free state) in a direction in which the curvature becomes smaller. As a result, the left and right walls 11 and 12 of the holding wall 8 sandwich the structure 2 by the elastic restoring force. Further, the tightening wall 9 of the holding body 4 is pressed against the holding wall 21 of the connecting body 5 by the elastic restoring force of the left and right walls 11 and 12, and therefore, the holding projection 18 and the engaging hole 25 are engaged with each other. It becomes more difficult to release the combined state, and both 4 and 5 can be firmly integrated.

ここで、構造体２への取付金具１の固定方法の一例を説明する。図９（ａ）に示すように、まず、第１スリット１７の開放部分を上向きにした状態で、自由状態の抱持体４の締付壁９のそれぞれを左右方向へ引張り、一対の締付壁９の前端どうしの距離が、構造体２の左右幅寸法Ｗ２を超える程度まで拡開させて、一対の締付壁９で構造体２の後部を挟み込む（図９（ａ）の二点鎖線参照）。この状態から、一対の前壁１３が構造体２の左右側面前端を乗り越えるように抱持体４を前方へ押し込むことにより、図２に示す状態に抱持体４を構造体２に外嵌装着できる。このとき、左右壁１１・１２間の間隙寸法Ｗ１と構造体２の左右幅寸法Ｗ２との寸法関係により左右壁１１・１２は拡開状に弾性変形しており、その弾性復元力で抱持体４は仮保持される。 Here, an example of a method of fixing the mounting bracket 1 to the structure 2 will be described. As shown in FIG. 9A, first, with the open portion of the first slit 17 facing upward, each of the tightening walls 9 of the free-standing holding body 4 is pulled in the left-right direction, and a pair of tightening is performed. The distance between the front ends of the wall 9 is widened to such an extent that it exceeds the left-right width dimension W2 of the structure 2, and the rear portion of the structure 2 is sandwiched between the pair of tightening walls 9 (two-dot chain line in FIG. 9A). reference). From this state, the holding body 4 is pushed forward so that the pair of front walls 13 get over the front ends of the left and right side surfaces of the structure 2, so that the holding body 4 is fitted onto the structure 2 in the state shown in FIG. can. At this time, the left and right walls 11 and 12 are elastically deformed in an expansive manner due to the dimensional relationship between the gap dimension W1 between the left and right walls 11 and 12 and the left and right width dimension W2 of the structure 2, and the left and right walls 11 and 12 are held by the elastic restoring force. Body 4 is temporarily held.

次いで、一対の締付壁９を密着させるように抱持体４の前側を左右方向に収縮させ、この状態で一対の挟持壁２１で一対の締付壁９を挟み込むように連結体５を装着し、保持突起１８と係合孔２５とを係合させることにより、抱持体４と連結体５とを一体化することができる。これにより、構造体２と抱持体４とが圧嵌係合され、構造体２に取付金具１を固定することができる。このとき、連結部２８を貫通孔形態にする場合には、第２スリット２４の開放部分が下向きになるように連結体５を装着し、フック形態にする場合には、第２スリット２４の開放部分が上向きになるように連結体５を装着する。また、貫通孔形態の連結部２８に無端環状の取付対象３を連結したい場合には、仮保持状態の抱持体４に対して第１スリット１７を介して第１通孔１６に取付対象３を引っ掛け、この状態で第２スリット２４の開放部分を下向きにした連結体５を上方から抱持体４に装着する。 Next, the front side of the holding body 4 is contracted in the left-right direction so that the pair of tightening walls 9 are brought into close contact with each other, and in this state, the connecting body 5 is attached so as to sandwich the pair of tightening walls 9 with the pair of holding walls 21. Then, by engaging the holding protrusion 18 and the engaging hole 25, the holding body 4 and the connecting body 5 can be integrated. As a result, the structure 2 and the holding body 4 are press-fitted and engaged with each other, and the mounting bracket 1 can be fixed to the structure 2. At this time, when the connecting portion 28 is in the form of a through hole, the connecting body 5 is attached so that the open portion of the second slit 24 faces downward, and when the connecting portion 28 is in the hook form, the second slit 24 is opened. The connecting body 5 is attached so that the portion faces upward. Further, when it is desired to connect the endless annular mounting target 3 to the connecting portion 28 in the form of a through hole, the mounting target 3 is connected to the first through hole 16 via the first slit 17 with respect to the holding body 4 in the temporarily held state. In this state, the connecting body 5 with the open portion of the second slit 24 facing downward is attached to the holding body 4 from above.

構造体２から取付金具１を取り外したいときは、抱持体４から連結体５を分離し、構造体２から抱持体４を分離すればよい。抱持体４から連結体５を分離させるとき、締付壁９の上下寸法Ｈ１よりも挟持壁２１の上下寸法Ｈ２が大きく形成されているので、連結体５を上方から下方へ、または下方から上方へ移動操作するとき、連結体５のみに操作力を作用させることができる。従って、締付壁９の上下寸法Ｈ１よりも挟持壁２１の上下寸法Ｈ２が小さく形成されている場合、または締付壁９の上下寸法Ｈ１と挟持壁２１の上下寸法Ｈ２とは同寸法に形成されている場合に比べて、分離操作を容易に行うことができる。 When it is desired to remove the mounting bracket 1 from the structure 2, the connecting body 5 may be separated from the holding body 4, and the holding body 4 may be separated from the structure 2. When the connecting body 5 is separated from the holding body 4, the vertical dimension H2 of the holding wall 21 is formed larger than the vertical dimension H1 of the tightening wall 9, so that the connecting body 5 is formed from above to below or from below. When the operation is moved upward, the operating force can be applied only to the connecting body 5. Therefore, when the vertical dimension H2 of the holding wall 21 is formed smaller than the vertical dimension H1 of the tightening wall 9, or the vertical dimension H1 of the tightening wall 9 and the vertical dimension H2 of the holding wall 21 are formed to be the same size. The separation operation can be easily performed as compared with the case where the separation operation is performed.

本実施例の抱持体４はばね鋼で形成されている。厚み寸法が同一の場合、ばね鋼の弾性限界は一般構造用の鋼のそれよりも高く、そのため抱持体４を大きく拡開変形させることができるので、構造体２に抱持体４を装着する際、あるいは構造体２から抱持体４を分離する際に、抱持体４が弾性限界を超えて破損するのを可及的に阻止することができる。 The holding body 4 of this embodiment is made of spring steel. When the thickness dimensions are the same, the elastic limit of the spring steel is higher than that of the steel for general structure, so that the holding body 4 can be greatly expanded and deformed. Therefore, the holding body 4 is attached to the structure 2. When the hugging body 4 is separated from the structure 2, the hugging body 4 can be prevented from being damaged beyond the elastic limit as much as possible.

図１０は、本実施例に係る取付金具１の使用形態を示しており、階段手摺１００と防護柵１０１との間の通路用間隙１０２に、取付金具１を用いて規制チェーン１０５を設けている。また、階段手摺１００および防護柵１０１の高さ方向の中途部に、取付金具１を用いてガードワイヤー１０６を設けている。規制チェーン１０５は、チェーン本体１１０と、チェーン本体１１０の一端に設けられるカラビナ１１１と、カラビナ１１１が掛止されるリング体１１２とで構成されている。また、ガードワイヤー１０６は、ワイヤー体１１３と、ワイヤー体１１３の両端にそれぞれ設けられて、ワイヤー体１１３にテンションを付与した状態で保持するテンショナー１１４とで構成されている。 FIG. 10 shows a usage pattern of the mounting bracket 1 according to the present embodiment, in which the mounting bracket 1 is used to provide the regulation chain 105 in the passage gap 102 between the staircase handrail 100 and the guard fence 101. .. Further, a guard wire 106 is provided in the middle of the staircase handrail 100 and the guard fence 101 in the height direction by using the mounting bracket 1. The regulation chain 105 is composed of a chain main body 110, a carabiner 111 provided at one end of the chain main body 110, and a ring body 112 on which the carabiner 111 is hooked. Further, the guard wire 106 is composed of a wire body 113 and a tensioner 114 provided at both ends of the wire body 113 and holding the wire body 113 in a tensioned state.

リング体１１２は、階段手摺１００の端部の支柱１２０（構造体２）に、連結部２８を貫通孔形態にした取付金具１を用いて連結されており、チェーン本体１１０の他端は、防護柵１０１の端部の支柱１２１（構造体２）に、連結部２８を貫通孔形態にした取付金具１を用いて連結されている。開閉ゲートを操作してカラビナ１１１をリング体１１２に係止することにより、チェーン本体１１０を支柱１２０・１２１間に掛け渡して通路用間隙１０２の通行を規制できる。 The ring body 112 is connected to the support column 120 (structure 2) at the end of the staircase handrail 100 by using a mounting bracket 1 in which the connecting portion 28 is in the form of a through hole, and the other end of the chain body 110 is protected. The connecting portion 28 is connected to the support column 121 (structure 2) at the end of the fence 101 by using a mounting bracket 1 in the form of a through hole. By operating the opening / closing gate to lock the carabiner 111 to the ring body 112, the chain body 110 can be hung between the columns 120 and 121 to restrict the passage of the passage gap 102.

ガードワイヤー１０６の各テンショナー１１４は、階段手摺１００の直線部、および傾斜部の両端部の支柱１２０・１２０に、連結部２８を貫通孔形態にした取付金具１を用いて連結されている。各テンショナー１１４は連結孔２９を介してねじ込まれたボルトにより取付金具１に締結固定される。階段手摺１００の直線部、および傾斜部の中間部分の支柱１２０には、連結部２８をフック形態にした取付金具１を固定して、ワイヤー体１１３の垂れ下がりや移動を規制している。 Each tensioner 114 of the guard wire 106 is connected to the straight portion of the staircase handrail 100 and the columns 120 and 120 at both ends of the inclined portion by using the mounting bracket 1 having the connecting portion 28 in the form of a through hole. Each tensioner 114 is fastened and fixed to the mounting bracket 1 by a bolt screwed through the connecting hole 29. A mounting bracket 1 in which the connecting portion 28 is in the form of a hook is fixed to the straight portion of the staircase handrail 100 and the support column 120 in the intermediate portion of the inclined portion to regulate the hanging and movement of the wire body 113.

上記のように、本実施例の取付金具１においては、既存の階段手摺１００や防護柵１０１に孔開け加工を施すことなく、規制チェーン１０５やガードワイヤー１０６を後付けするため取付金具１を簡便に設けることが可能となる。また、規制チェーン１０５やガードワイヤー１０６が必要なくなったときには、抱持体４から連結体５を分離するだけで、階段手摺１００や防護柵１０１から取付金具１を取り外すことができるので、取付用の孔などが残ることなく現状回復が容易な点でも有利である。 As described above, in the mounting bracket 1 of the present embodiment, the mounting bracket 1 is simply attached because the regulation chain 105 and the guard wire 106 are retrofitted without drilling holes in the existing stair railing 100 and the guard fence 101. It becomes possible to provide. Further, when the regulation chain 105 and the guard wire 106 are no longer needed, the mounting bracket 1 can be removed from the staircase handrail 100 and the guard fence 101 simply by separating the connecting body 5 from the holding body 4, so that the mounting bracket 1 can be removed. It is also advantageous in that it is easy to recover the current situation without leaving holes.

以上のように、本実施例の取付金具１によれば、抱持体４に連結体５を装着することにより、構造体２と抱持体４とが圧嵌係合されるように構成したので、抱持体４に連結体５を装着するだけの簡単な動作で、構造体２に取付金具１を固定することができる。また、抱持体４に連結体５を装着したとき、締付壁９に形成された第１スリット１７に連結体５の挟持壁２１が重畳して、連結部２８に貫通状の連結孔２９が形成されるようにしたので、無端環状の取付対象３の一部を第１スリット１７を介して第１通孔１６に位置させ、この状態で抱持体４に連結体５を装着することにより、連結部２８の連結孔２９に無端環状の取付対象３を連結することができる。従って、抱持体４への連結体５の装着動作によって、構造物２に取付金具１を簡便に固定でき、さらに取付金具１に無端環状の取付対象３を直接連結することができる。 As described above, according to the mounting bracket 1 of the present embodiment, the structure 2 and the holding body 4 are press-fitted and engaged with each other by mounting the connecting body 5 on the holding body 4. Therefore, the mounting bracket 1 can be fixed to the structure 2 by a simple operation of attaching the connecting body 5 to the holding body 4. Further, when the connecting body 5 is attached to the holding body 4, the holding wall 21 of the connecting body 5 is superimposed on the first slit 17 formed in the tightening wall 9, and the connecting hole 29 is penetrating the connecting portion 28. Is formed. Therefore, a part of the endless annular mounting target 3 is positioned in the first through hole 16 via the first slit 17, and the connecting body 5 is mounted on the holding body 4 in this state. As a result, the endless annular mounting target 3 can be connected to the connecting hole 29 of the connecting portion 28. Therefore, the mounting bracket 1 can be easily fixed to the structure 2 by the mounting operation of the connecting body 5 to the holding body 4, and the endless annular mounting target 3 can be directly connected to the mounting bracket 1.

加えて、断面矩形状の構造体２に抱持体４を外嵌装着し、さらに外嵌装着した抱持体４に連結体５を装着したとき、内凹み湾曲状に形成された左右壁１１・１２が、その曲率が小さくなるように弾性変形した状態で構造体２と抱持壁８とが圧嵌係合されるようにしたので、左右壁１１・１２の弾性復元力で抱持壁８と構造体２との間の摩擦力を増大させることができる。従って、構造体２に対して取付金具１をより強固に固定することができる。 In addition, when the holding body 4 is externally fitted to the structure 2 having a rectangular cross section and the connecting body 5 is mounted to the externally fitted holding body 4, the left and right walls 11 formed in an inwardly concave curved shape. Since the structure 2 and the holding wall 8 are press-fitted and engaged with each other in a state where the structure 2 is elastically deformed so that its curvature becomes small, the holding wall is subjected to the elastic restoring force of the left and right walls 11 and 12. The frictional force between the 8 and the structure 2 can be increased. Therefore, the mounting bracket 1 can be more firmly fixed to the structure 2.

締付壁９に保持突起１８を形成し、挟持壁２１に保持突起１８と係合する係合孔２５を形成したので、連結体５が抱持体４から不用意に分離されることを回避して、構造体２から取付金具１が脱落するのを防止できる。また、保持突起１８が係合孔２５に嵌り込む際の節度感で、抱持体４の適正位置に連結体５が装着されたことを目視することなく認識することができる。 Since the holding protrusion 18 is formed on the tightening wall 9 and the engaging hole 25 that engages with the holding protrusion 18 is formed on the holding wall 21, it is possible to prevent the connecting body 5 from being inadvertently separated from the holding body 4. Therefore, it is possible to prevent the mounting bracket 1 from falling off from the structure 2. Further, it is possible to recognize that the connecting body 5 is mounted at an appropriate position of the holding body 4 without visually recognizing the moderation when the holding protrusion 18 is fitted into the engaging hole 25.

抱持体４に対する連結体５の装着姿勢を変更することにより、連結部２８の形態を、連結孔２９が形成される貫通孔形態と、フック溝３０が形成されるフック形態とに、選択的に切換え可能に構成したので、一組の抱持体４と連結体５とからなる取付金具１で、連結部２８を貫通孔形態とフック形態のいずれかに切換えることができ、従って、取付金具１の利便性を向上し、また各形態毎に取付金具１を用意するコストを削減することができる。 By changing the mounting posture of the connecting body 5 with respect to the holding body 4, the form of the connecting portion 28 is selectively selected into a through hole form in which the connecting hole 29 is formed and a hook form in which the hook groove 30 is formed. Since it is configured to be switchable to, the connecting portion 28 can be switched to either the through hole form or the hook form by the mounting bracket 1 composed of a set of the holding body 4 and the connecting body 5. Therefore, the mounting bracket It is possible to improve the convenience of 1 and reduce the cost of preparing the mounting bracket 1 for each form.

図１１から図１５は、連結体５および締付壁９の変形例を示しており、本変形例の連結体５は、連結部２８を貫通孔形態とするとき、橋絡壁２２が下側に位置する状態で締付壁９に装着され、連結部２８をフック形態とするとき、橋絡壁２２が前側に位置する状態で締付壁９に装着される。すなわち、上記実施例とは、締付壁９に対する連結体５の装着姿勢が異なる。装着姿勢における橋絡壁２２の位置が異なるので、係合孔２５は挟持壁３１の前端側（橋絡壁２２側）にも設けられている。第１通孔１６の直径寸法と、第１スリット１７の幅寸法とは同一に形成され、第２通孔２３の直径寸法と、第２スリット２４の幅寸法とは同一に形成されている。他は上記実施例と同じであるので、同じ部材に同じ符号を付してその説明を省略する。以下の変形例においても同じとする。図１３は抱持体４を正面、背面、平面、底面、および右側面から見た形状を示しており、図１４は連結体５を正面、背面、平面、底面、および右側面から見た形状を示しており、図１５は連結部２８を貫通孔形態とした状態の取付金具１を正面、背面、平面、底面、および右側面から見た形状を示している。 11 to 15 show a modified example of the connecting body 5 and the tightening wall 9. In the connecting body 5 of this modified example, when the connecting portion 28 is in the form of a through hole, the bridge wall 22 is on the lower side. When the connecting portion 28 is in the form of a hook, the bridge wall 22 is mounted on the tightening wall 9 in a state of being located on the front side. That is, the mounting posture of the connecting body 5 with respect to the tightening wall 9 is different from that of the above embodiment. Since the positions of the bridge wall 22 in the mounting posture are different, the engagement hole 25 is also provided on the front end side (bridge wall 22 side) of the holding wall 31. The diameter dimension of the first through hole 16 and the width dimension of the first slit 17 are formed to be the same, and the diameter dimension of the second through hole 23 and the width dimension of the second slit 24 are formed to be the same. Since the other parts are the same as those in the above embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted. The same applies to the following modified examples. FIG. 13 shows the shape of the hugging body 4 as viewed from the front, back, plane, bottom, and right side, and FIG. 14 shows the shape of the connecting body 5 as viewed from the front, back, plane, bottom, and right side. FIG. 15 shows the shape of the mounting bracket 1 in the state where the connecting portion 28 is in the form of a through hole as viewed from the front surface, the back surface, the flat surface, the bottom surface, and the right side surface.

図１６は、連結体５および締付壁９の別の変形例を示しており、本変形例の連結体５は、第２通孔２３および第２スリット２４で形成される切欠きが、橋絡壁２２の対辺部（後周縁）に開放されている点と、係合孔２５が締付壁９の保持突起１８に対応するように挟持壁２１の対角位置に形成される点が先の実施例の連結体５と異なる。このように第２スリット２４の形成位置を変更した場合でも、連結部２８を貫通孔形態とフック形態とに選択的に切換えることができる。なお、第２スリット２４の形成位置の変更にともない保持突起１８と係合孔２５の形成位置も変更することが好ましい。 FIG. 16 shows another modified example of the connecting body 5 and the tightening wall 9, and the connecting body 5 of this modified example has a notch formed by the second through hole 23 and the second slit 24 as a bridge. The point that is open to the opposite side (rear peripheral edge) of the entangled wall 22 and the point that the engaging hole 25 is formed at a diagonal position of the holding wall 21 so as to correspond to the holding protrusion 18 of the tightening wall 9 are first. It is different from the connecting body 5 of the embodiment. Even when the formation position of the second slit 24 is changed in this way, the connecting portion 28 can be selectively switched between the through hole form and the hook form. It is preferable to change the forming positions of the holding protrusion 18 and the engaging hole 25 as the forming position of the second slit 24 is changed.

図１７は、連結体５および締付壁９のさらに別の変形例を示しており、本変形例の連結体５は、先の変形例同様、第２通孔２３および第２スリット２４で形成される切欠きが、橋絡壁２２の対辺部（後周縁）に開放されている。また、第１通孔１６および第１スリット１７で形成される切欠きが、締付壁９の前周縁に開放されている。この変形例においては、貫通孔形態の連結部２８にすることができる。連結体５は、抱持体４に対して上方、下方、あるいは前方から装着できるので、締付壁９の上方、下方、あるいは前方のうち、いずれか一方に障害物がなければ構造体２に取付金具１を固定することができる。 FIG. 17 shows yet another modification of the connecting body 5 and the tightening wall 9, and the connecting body 5 of this modification is formed by the second through hole 23 and the second slit 24 as in the previous modification. The notch to be formed is opened to the opposite side (rear peripheral edge) of the bridge wall 22. Further, a notch formed by the first through hole 16 and the first slit 17 is opened to the front peripheral edge of the tightening wall 9. In this modification, the connecting portion 28 in the form of a through hole can be used. Since the connecting body 5 can be attached to the holding body 4 from above, below, or from the front, the structure 2 can be attached to the structure 2 if there is no obstacle in any one of the above, below, or the front of the tightening wall 9. The mounting bracket 1 can be fixed.

図１８は構造体２が角パイプであり、その断面が正方形である場合の抱持体４の変形例を示している。図１８に示す抱持体４は先の実施例の抱持壁８の各壁１０〜１３の寸法が異なるだけで構成は同一である。 FIG. 18 shows a modified example of the holding body 4 when the structure 2 is a square pipe and its cross section is square. The hugging body 4 shown in FIG. 18 has the same configuration except that the dimensions of the walls 10 to 13 of the hugging wall 8 of the previous embodiment are different.

図１９は構造体２が丸パイプであり、その断面が円形である場合の抱持体４の変形例を示している。本変形例の抱持壁８は、前方に切欠き部３４を有する左右の円環壁３５・３６からなる円環状に形成される点が上記の実施例と異なる。抱持壁８の左円環壁３５および右円環壁３６は、構造体２の外周面の曲率よりも小さい曲率の緩曲円環状に形成されており、自由状態における抱持壁８は、前後方向に長軸、左右方向に短軸を持つ略楕円状に形成されている（図１９の二点鎖線参照）。抱持体４に連結体５を装着したとき、緩曲円環状に形成された左右の円環壁３５・３６は、構造体２の外周面に沿うように弾性変形されている。 FIG. 19 shows a modified example of the holding body 4 when the structure 2 is a round pipe and its cross section is circular. The holding wall 8 of this modification is different from the above embodiment in that it is formed in an annular shape composed of left and right annular walls 35 and 36 having a notch 34 in the front. The left ring wall 35 and the right ring wall 36 of the holding wall 8 are formed in a gently curved ring shape having a curvature smaller than the curvature of the outer peripheral surface of the structure 2, and the holding wall 8 in the free state is formed. It is formed in a substantially elliptical shape having a long axis in the front-rear direction and a short axis in the left-right direction (see the two-point chain line in FIG. 19). When the connecting body 5 is attached to the holding body 4, the left and right annular walls 35 and 36 formed in a gently curved annular shape are elastically deformed along the outer peripheral surface of the structure 2.

上記のように、緩曲円環状に形成された左右の円環壁３５・３６が、構造体２の外周面に沿うように弾性変形した状態で構造体２と抱持壁８とが圧嵌係合されるようにしたので、上記の実施例と同様に、緩曲円環状に形成された左右の円環壁３５・３６の弾性復元力で抱持壁８と構造体２との間の摩擦力を増大させることができるので、構造体２に対して取付金具１をより強固に固定することができる。 As described above, the structure 2 and the holding wall 8 are press-fitted in a state where the left and right annular walls 35 and 36 formed in a gently curved annulus are elastically deformed along the outer peripheral surface of the structure 2. Since they are engaged with each other, the elastic restoring force of the left and right annular walls 35 and 36 formed in a gently curved annular shape is applied between the holding wall 8 and the structure 2 in the same manner as in the above embodiment. Since the frictional force can be increased, the mounting bracket 1 can be more firmly fixed to the structure 2.

上記の実施例では、締付壁９の上下寸法Ｈ１は、抱持壁８の上下寸法と同寸法に設定したが、大きくあるいは小さく設定することもできる。抱持壁８は上下寸法が一定の帯状に形成したが、必ずしも上下寸法は一定である必要はない。また、抱持壁８に開口や突起を設けることもできる。上記の抱持体４は１個のパーツで構成したが、例えば左右２個に分割した半割体を一体化して構成することもできる。この場合には、一対の半割体を例えば締結体などの接続構造で一体にすればよい。連結体５の挟持壁２１は少なくとも締付壁９の第１スリット１７に重畳できる形状であればよく、上記実施例の締付壁９の構成に限られない。 In the above embodiment, the vertical dimension H1 of the tightening wall 9 is set to be the same as the vertical dimension of the holding wall 8, but it can also be set to be large or small. The holding wall 8 is formed in a strip shape having a constant vertical dimension, but the vertical dimension does not necessarily have to be constant. Further, the holding wall 8 may be provided with an opening or a protrusion. The above-mentioned hugging body 4 is composed of one part, but for example, a half-split body divided into two left and right parts can be integrally formed. In this case, the pair of halves may be integrated by a connecting structure such as a fastening body. The holding wall 21 of the connecting body 5 may have at least a shape that can be superimposed on the first slit 17 of the tightening wall 9, and is not limited to the configuration of the tightening wall 9 of the above embodiment.
