Description

コンクリート構築物を構築する際に、メタルフォームと呼ばれる金属製の型枠が用いられ、例えば、ＲＣ柱を構築する際、ＲＣ柱の幅に合わせてシステム柱型枠であるメタルフォームを設置するのであるが、メタルフォームの周囲に所定の支保工（コラムクランプ、端太など）を配し、該支保工をメタルフォームに押圧して固定して、当該メタルフォームの寸法精度などを維持するようにしている。   When building a concrete structure, a metal formwork called a metal foam is used. For example, when building an RC pillar, a metal form that is a system pillar formwork is installed according to the width of the RC pillar. However, a predetermined support work (column clamp, edge thickness, etc.) is placed around the metal foam, and the support work is pressed and fixed to the metal foam to maintain the dimensional accuracy of the metal foam. Yes.

本発明は、このような支保工をメタルフォームに押圧して組付けるために用いる締め付け金具に関するものである。   The present invention relates to a fastening fitting used for pressing and assembling such a support work to a metal foam.

なお、複数のメタルフォームを直線状に連結させた場合であっても、そのメタルフォームの通りを精度良くするために支保工に固定することもあるが、このメタルフォームは、それら連結部分に生じる隙間をなくすために各連結面が外アールに形成されて若干湾曲するようになっていることから、締付け金具により支保工にメタルフォームを強固に押圧する必要がある。   In addition, even when a plurality of metal foams are connected in a straight line, the metal foam may be fixed to a supporting work in order to improve the accuracy of the metal foam, but this metal foam is generated at these connecting parts. In order to eliminate the gap, each connection surface is formed in an outer radius and is slightly curved. Therefore, it is necessary to firmly press the metal foam against the support by the fastening bracket.

従って、本発明はメタルフォームと鋼製の支保工（端太材）を用いるものであれば、不都合なく適用でき、特にシステム柱型枠に限定されるものではない。   Therefore, the present invention can be applied without any problem as long as it uses a metal foam and a steel support (end thick material), and is not particularly limited to the system column formwork.

従来の上記締付け金具は支保工を取り付ける、または取り外すにあたって、その支保工を保持させながら締付け金具を締め付ける、又は、押圧力を解除するといった作業を行うことから常に複数の施工者が必要になり、作業性が非常に悪いという問題があった。   When attaching or removing a support work, the above-mentioned conventional fastening metal fittings always require a plurality of installers to perform work such as tightening the clamp fitting or releasing the pressing force while holding the support work. There was a problem that workability was very bad.

このような問題を解消するため、支保工の取付け、及び、取り外しが容易かつ安全に行うことができる締付け金具が開示されている（例えば、特許文献１）。   In order to solve such a problem, a fastening fitting that can be easily and safely attached and detached from a support work is disclosed (for example, Patent Document 1).

この文献１所載の締付け金具は、メタルフォームのリブに設けた透孔に係止するフックを一端に備え、他端にナット部材を螺合する雄ねじを設けた締付けボルト（ブラケット部材）と、該締付けボルトの中間部に設け、しかも、前記メタルフォームのリブに接触して前記締付けボルトを水平に維持する防傾片（支持片）および前記締付けボルトを挿通し、しかも、前記ナット部材を締め付けることによって前記締付けボルト上の断面矩形状の支保工の前面に接触してこれを前記メタルフォーム方向に押圧する挟持部材（保持部材）とで構成したもので、締付けボルトの一端（先端）に設けたフックをメタルフォーム側の透孔に挿通、係止させてピン支持させ、防傾片をメタルフォーム（のリブの縁）に当接するようにして締付け金具自体が常に水平状態を保ち、支保工を載置しても安定的な支持が可能になることから、１人の施工者で支保工を固定することができるものである。   The fastening bracket described in this document 1 includes a fastening bolt (bracket member) provided at one end with a hook that engages with a through hole provided on a rib of a metal foam, and provided with a male screw that engages a nut member at the other end. Provided in an intermediate portion of the tightening bolt, and further, an anti-tilt piece (support piece) that contacts the rib of the metal foam and keeps the tightening bolt horizontal, and the tightening bolt are inserted, and the nut member is tightened This is composed of a clamping member (holding member) that contacts and presses the front surface of the supporting work having a rectangular cross section on the clamping bolt in the metal foam direction, and is provided at one end (tip) of the clamping bolt. Insert the hook into the through hole on the metal foam side and lock it so that the pin is supported, and the clamping bracket itself is always in contact with the metal foam (rib edge). Maintaining the horizontal state, since it becomes possible also stable support by placing the 支保 Engineering, in which it is possible to fix the 支保 Engineering in one of the builders.

しかしながら、上記文献に記載の締付け金具は、締付けボルト上に支保工を載置するとともに、締付けボルトを挿通した挟持部材によって支保工を押圧する構造であるため、ナット部材による締付けの方向（締付けボルトの軸方向）と支保工から受ける反力の方向（中立軸の位置）とは互いに一致せず偏心しており、挟持部材にはモーメントが生じてしまう。即ち、締め付ける全ての力が挟持部材には伝達されずに、締付けボルト側に力が逃げてしまうため、強固な固定力が得られないという欠点があった。また、さらにナット部材を締め付けて強固に固定させようとしても、前記モーメントによって平板状である挟持部材などが変形（破損）してしまう虞があるとともに、その変形により支保工の中立軸（高さ方向）より下部の位置で締付け力が生じてしまうため、挟持部材が支保工から外れる方向に分力が働いてしまうといった問題もあった。   However, the fastening bracket described in the above document has a structure in which a supporting work is placed on the fastening bolt and the supporting work is pressed by a clamping member through which the fastening bolt is inserted. The axial direction) and the direction of the reaction force received from the support (the position of the neutral axis) are not coincident with each other and are eccentric, and a moment is generated in the clamping member. That is, all the tightening force is not transmitted to the clamping member, and the force escapes to the tightening bolt side, so that a strong fixing force cannot be obtained. Further, even if the nut member is further tightened to be firmly fixed, there is a risk that the plate-like holding member or the like may be deformed (damaged) by the moment, and the neutral shaft (height of the support work) may be deformed by the deformation. Since a tightening force is generated at a position lower than (direction), there is also a problem that a component force acts in a direction in which the clamping member is detached from the support work.

ちなみに、上記文献にはこの欠点を解消する手段として、挟持部材の貫通孔にスリーブを突設することが記されているが、例え、スリーブを設けたとしても偏心していることに変わりはないことから、締付け力によって挟持部材にモーメントが生じてしまい、前述した問題は解決されない。   By the way, in the above-mentioned document, as a means for solving this drawback, it is described that a sleeve is protruded from the through hole of the clamping member, but even if a sleeve is provided, it is still eccentric. Therefore, a moment is generated in the clamping member by the tightening force, and the above-described problem cannot be solved.

また、上記文献に記載の締付け金具は、ナット部材による締め付けの方向（締付けボルトの軸方向）と、メタルフォームのリブ部の縁に当接することで防傾片が受ける反力の方向とが互いに一致せず偏心しているため、ナット部材を締め付けてもリブ部の縁に当接状態で支持されている防傾片が水平方向に滑ってしまうことから、固定する作業において効率性に問題があった。   Further, in the fastening metal fitting described in the above document, the direction of fastening by the nut member (axial direction of the fastening bolt) and the direction of the reaction force received by the anti-tilt piece by contacting the edge of the rib portion of the metal foam are mutually Since they do not match and are eccentric, even if the nut member is tightened, the anti-tilt piece that is supported in contact with the edge of the rib portion will slide in the horizontal direction. It was.

本発明は上記問題に着目し、メタルフォームを支保工により固定する際に、支保工をメタルフォームに効率よく強固に締め付けることが可能な締付け金具を提供することを目的として創案したものである。   The present invention has been devised for the purpose of providing a fastening bracket capable of efficiently and firmly tightening a support work to the metal foam when the metal foam is fixed by the support work, paying attention to the above problems.

メタルフォームに設けたクリップ孔等の透孔に係止するフックを一端に備え、他端にナット部材を螺合する雄ねじを設けた締付けボルトと、該締付けボルトの中間部に設け、しかも、前記メタルフォームに接触して前記締付けボルトを水平に保持するための防傾片および前記締付けボルトを挿通し、前記ナット部材を締め付けることによって前記締付けボルト上の、断面略矩形状の支保工の前面に接触して該支保工を前記メタルフォーム方向に押圧する挟持部材とから成り、支保工の前記前面に対し、前記挟持部材の、前記前面との接触縁を、上方に至るに従って次第に前記メタルフォームに近接する傾斜縁で構成したことを基本的手段とし、この基本的手段に防傾片を、メタルフォームに設けたリブを内側に係合する断面溝形とした点を付加することにより締付けボルトによって支保工を安定した状態で受支し、ナット部材を締め付けたとしても、水平方向に滑ってしまうことなく、また、水平方向に力が逃げてしまうことなく締付け金具を固定することができ、締付け作業の効率を図れる締付け金具を提供できる。   A fastening bolt provided at one end with a hook that engages with a through-hole such as a clip hole provided in the metal foam, and provided with a male screw that engages a nut member at the other end, and provided at an intermediate portion of the fastening bolt; Inserting an anti-tilt piece for holding the fastening bolt horizontally in contact with the metal foam and the fastening bolt, and tightening the nut member to the front surface of the support work having a substantially rectangular cross section on the fastening bolt A holding member that contacts and presses the support work in the direction of the metal foam, and gradually contacts the front edge of the support work with the front surface of the holding member toward the metal foam. The basic means is that it is composed of adjacent inclined edges, and this basic means is provided with a point that has a tilt-proof piece and a cross-sectional groove shape that engages the rib provided on the metal foam inside. By doing so, even if the support is stably supported by the tightening bolt and the nut member is tightened, the tightening bracket is fixed without slipping in the horizontal direction and without causing force to escape in the horizontal direction. Therefore, it is possible to provide a fastening bracket that can improve the efficiency of the fastening work.

なお、接触縁の傾斜角度は特に限定しないが、支保工の高さ方向の中心位置（中立軸）より上部で接触させるように傾けると、その接触点の位置においては押圧する力だけでなく、傾きに対して直角方向（図面上、斜め下方）への分力も働くことから、確実に支保工を締め付けることができる。   In addition, although the inclination angle of the contact edge is not particularly limited, if the contact edge is tilted so as to contact the upper part from the center position (neutral axis) in the height direction, not only the pressing force at the position of the contact point, Since the component force in the direction perpendicular to the inclination (in the drawing, diagonally downward) also works, the support work can be securely tightened.

さらに、本発明の締付け金具においても、締付け位置と支保工から受ける反力位置とは偏心することになるが、支保工との接触縁は傾けられて設けられていることから、例え、締め付けに伴うモーメントによって挟持部材に変形が生じたとしても、その変形は上部の接触点を中心として挟持部材の前面で支保工の前面を押圧（接触）するような状態になっていくため、支保工に対しては、ますます強固に締め付けることができる。   Furthermore, in the fastening bracket of the present invention, the tightening position and the reaction force position received from the support work are eccentric, but the contact edge with the support work is provided at an angle, so for example, tightening Even if the clamping member is deformed by the accompanying moment, the deformation will be in a state where the front surface of the clamping member is pressed (contacted) with the front surface of the clamping member around the upper contact point. On the other hand, it can tighten more and more firmly.

本発明によれば、メタルフォームを支保工により固定する（メタルフォームに支保工を組付ける）に際し、該支保工を略水平状態に保持すると共に、締付けボルトにおいて挟持材が支保工に接触させることができるから、支保工をメタルフォームに効率よく強固に締め付けることができ、使用勝手の良好な締付け金具を提供できる。   According to the present invention, when the metal foam is fixed by a support (attaching the support to the metal foam), the support is held in a substantially horizontal state, and the clamping material is brought into contact with the support at the tightening bolt. Therefore, it is possible to efficiently and firmly fasten the support work to the metal foam, and to provide a clamp that is easy to use.

実施例の締付け金具Ａは、システム柱型枠１に該システム型枠１の寸法精度などを維持するために型枠１を取り囲んで支保工（型枠クランプ）２を組付ける（固定する）ための治具として適用したもので、支保工２は、前記型枠１を介して対向配置する一対の略Ｌ字形の部材２´，２´を緊締材３で互いに接続する一方、型枠２に対して締付け金具Ａ用いて組付け、前記システム柱型枠１の構築状態を安定的に維持するものである。   The fastening bracket A of the embodiment is used for assembling (fixing) a supporting work (formwork clamp) 2 around the formwork 1 to maintain the dimensional accuracy of the system formwork 1 in the system column formwork 1. The supporting work 2 connects a pair of substantially L-shaped members 2 ′ and 2 ′ arranged opposite to each other via the mold 1 with a fastening material 3, while On the other hand, it is assembled using the fastening bracket A, and the construction state of the system column mold 1 is stably maintained.

なお、支保工２は公知のものであるので（例えば、文献１)、詳細な説明は省略する。   In addition, since the support work 2 is a well-known thing (for example, literature 1), detailed description is abbreviate | omitted.

前記締付け金具Ａは、締付けボルト４、挟持部材５およびナット部材６で構成し、締付けボルト４は一端にＬ字形に屈曲して形成したフック７を備え、他端に雄ねじ８を形成した棒杆状の主体杆９の中間部に該主体杆９よりへの字状に突設して先端部１０´を主体杆９に対して直角方向に配した枝杆１０を連設し、枝杆１０の前記先端部１０´に型枠１側開口の断面溝形の防傾片１１を突設して成るものである。   The clamp A is composed of a clamp bolt 4, a clamping member 5 and a nut member 6. The clamp bolt 4 is provided with a hook 7 formed by bending an L-shape at one end, and a rod rod having a male screw 8 formed at the other end. A branch rod 10 is provided in a middle portion of the main rod 9 in a shape protruding from the main rod 9 and a tip portion 10 ′ is arranged in a direction perpendicular to the main rod 9. The tip portion 10 'is provided with a tilting piece 11 having a groove shape in the cross section of the opening on the mold 1 side.

主体杆９（フック７）は、型枠１の外面に備えたリブ１ａに設けたクリップ孔（必ずしもクリップ孔である必要はない）１２に挿通、係止できる程度の径を備え、また、防傾片１１は前記クリップ孔１２を備えた前記リブ１ａが内側に係合する程度の溝径を備えた溝状体で成るものである。そして、防傾片１１に、リブ１ａを係合したときに前記フック７はクリップ孔１２に挿通、係止した状態で全体が略水平になるようにしてあり、すなわち、クリップ孔１２とリブ１ａの先端（自由端）縁１ａ´との離開距離と、フック７と防傾片１１との間の投影距離をほぼ一致させてある。   The main rod 9 (hook 7) has a diameter that can be inserted and locked into a clip hole (not necessarily a clip hole) 12 provided in the rib 1a provided on the outer surface of the mold 1 and has a resistance. The inclined piece 11 is formed of a groove-like body having a groove diameter enough to engage the rib 1a provided with the clip hole 12 inward. When the rib 1a is engaged with the anti-tilt piece 11, the hook 7 is inserted into and locked into the clip hole 12 so that the whole is substantially horizontal, that is, the clip hole 12 and the rib 1a. The separation distance from the front end (free end) edge 1a ′ of the head and the projection distance between the hook 7 and the anti-tilt piece 11 are substantially the same.

挟持部材５は、締付けボルト４の前記主体杆９を挿通させて該主体杆９に移動自在に組付けた主体筒１３の周側に断面コ形の挟持片１４を突設したもので、挟持片１４は、中央部片１４ａの両側に側部片１４ｂ，１４ｂを相対して突設し、側部片１４ｂ，１４ｂの自由端部を該自由端部間に介在する前記主体筒１３に熔接して該主体筒１３とで前記挟持部材５を構成する。   The clamping member 5 is formed by projecting a clamping piece 14 having a U-shaped cross section on the peripheral side of a main cylinder 13 that is inserted in the main rod 9 of the tightening bolt 4 and is movably assembled to the main rod 9. The piece 14 is formed by projecting side pieces 14b and 14b on opposite sides of the central piece 14a, and welding the free ends of the side pieces 14b and 14b to the main cylinder 13 interposed between the free ends. Thus, the clamping member 5 is constituted by the main cylinder 13.

そして、挟持片１４は、主体筒からの突出量を、締付けボルト４の前記主体杆９で受支する前記支保工２（端太材、なお、図示のものは、角形鋼管で成るが溝形鋼やリップ溝形鋼で成るものでも不都合はない）の高さ（縦）幅より大きくし、側部片１４ｂ，１４ｂで構成する、前記フック７側の前端縁１４ｂ´に支保工２前面側の係合切欠１５を設け、該係合切欠１５を構成する前記支保工２（の上端部）の前面２´との接触縁１６を、前記主体筒１３側の下部から前記中央部片１４ａ側の上部に至るに従って次第に前記型枠１乃至支保工２側に近接する傾斜縁で構成したものである。   And the clamping piece 14 is the said supporting work 2 (end-end material, although the thing of illustration is a square-shaped steel pipe, although it is supported by the said main body rod 9 of the clamp | tightening bolt 4 with the amount of protrusions from a main pipe | tube. It is larger than the height (vertical) width of the steel or lip groove steel), and the front end edge 14b 'on the hook 7 side, which is composed of the side pieces 14b and 14b, is on the front side of the supporting work 2 The contact edge 16 with the front surface 2 ′ of the support work 2 (the upper end portion thereof) constituting the engagement notch 15 is provided from the lower part on the main cylinder 13 side to the central piece 14 a side. As it reaches the upper part, it is composed of an inclined edge that gradually approaches the mold 1 to the support 2 side.

前記ナット部材６は雄ねじ８に螺合して締付けボルト４の主体杆９に組付けたものである。   The nut member 6 is screwed into the male screw 8 and assembled to the main rod 9 of the tightening bolt 4.

そして、主体杆９の雄ねじ８の端末に圧平部を設けて、前記挟持部材５（主体筒１３)とナット部材６が締付けボルト４に一体的に組付けられ、前記の通り、締付け金具Ａを構成する。   Then, an applanation portion is provided at the end of the male screw 8 of the main rod 9, and the clamping member 5 (main cylinder 13) and the nut member 6 are assembled integrally with the tightening bolt 4. Configure.

しかして、締付けボルト４の主体杆９の先端に設けたフック７を型枠１のリブ１ａに備えたクリップ孔１２に挿通させ、該挿通させた状態を維持しつつ主体杆９を下向に回転させて防傾片１１にリブ１ａが係合するように倒伏させると、締付け金具Ａすなわち締付けボルト４はフック７のクリップ孔との挿通、係止関係と防傾片１１のリブ１ａに対する外側からの係合関係との２個所によってリブ１ａ（型枠１）に支持され、片持ち梁状にして型枠１より水平に突設されることになる。   Accordingly, the hook 7 provided at the tip of the main body 9 of the tightening bolt 4 is inserted into the clip hole 12 provided in the rib 1a of the mold 1, and the main body 9 is kept downward while maintaining the inserted state. When the rib 1a is rotated so that the rib 1a is engaged with the anti-tilt piece 11, the fastening metal A, that is, the tightening bolt 4, is inserted into the clip hole of the hook 7, and the locking relationship and the outer side of the anti-tilt piece 11 with respect to the rib 1a. Is supported by the rib 1a (form frame 1) at two points with the engagement relationship from the side, and is projected in a cantilever form from the mold 1 horizontally.

この状態で締付けボルト４上に支保工（端太材）２を載置すると、支保工２は同様にして型枠１に組付けた他の締付け金具とによって安定的に受支され、次いでナット部材６を締付けて挟持部材５の主体筒１３を支保工２乃至型枠１方向に前進させると、挟持部材５の挟持片１４に設けた接触縁１６はその傾斜形状によって支保工２の前面の上端部を押圧し、支保工２を型枠１（のリブ１ａ）と共に挟持し、支保工２は、実施例のシステム柱型枠１に組付けられるのである。   In this state, when the supporting work (end thick material) 2 is placed on the fastening bolt 4, the supporting work 2 is stably supported by other fastening fittings assembled to the mold 1 in the same manner, and then the nut. When the member 6 is tightened and the main cylinder 13 of the clamping member 5 is advanced in the direction of the support 2 or the mold 1, the contact edge 16 provided on the clamping piece 14 of the clamping member 5 is formed on the front surface of the support 2 by the inclined shape. The upper end is pressed to hold the support 2 together with the mold 1 (the rib 1a), and the support 2 is assembled to the system column mold 1 of the embodiment.

なお、締付けボルト４のフック７部の形状や防傾片、挟持部材の形態は特に限定されるものではないが、挟持部材５の挟持片１４については図に示すようなコ字状に折り曲げた形態にすると剛性面で有利であるとともに、挟持片１４と支保工２との接触が面全体ではなく２点で接触することになるので、ナット部材６の締付け力が挟持部材５を介して支保工２に効率よく伝達（押圧）することができる。   The shape of the hook 7 portion of the tightening bolt 4 and the shape of the anti-tilt piece and the clamping member are not particularly limited, but the clamping piece 14 of the clamping member 5 is bent into a U shape as shown in the figure. The configuration is advantageous in terms of rigidity, and the contact between the holding piece 14 and the support work 2 is not at the whole surface but at two points, so that the tightening force of the nut member 6 is supported through the holding member 5. It can be efficiently transmitted (pressed) to the work 2.
