しかしながら、前記ボルトをナットで緊締する際、前記両脚片の当止片が折板屋根のハゼ部を確実に挟着したときに、前記ボルト又はナットの締め付けを終えるのであるが、この挟着したときを判断するのは、締め付ける作業者の力加減によるものであるため、誤って前記ボルト又はナットを締め過ぎると、これらボルト又はナットの螺合部分やボルト頭部等を破損してしまうという問題があった。   However, when the bolts are tightened with nuts, the bolts or nuts are tightened when the retaining pieces of the leg pieces securely clamp the goby portion of the folded plate roof. Judging the time is due to the force of the operator tightening, so if you overtighten the bolt or nut by mistake, the screwed part of the bolt or nut, the bolt head, etc. will be damaged was there.

本発明は、かかる課題を解決することを目的とし、所定以上の力でボルト又はナットを締め付けることを確実に規制して、これらボルト又はナットの螺合部分やボルト頭部等の破損を確実に防止できる折板屋根用取付具を提供する。   The present invention aims to solve such a problem, and securely restricts the bolts or nuts to be tightened with a predetermined force or more, and ensures that the screwed portions of the bolts or nuts or the bolt heads are damaged. Provided is a folded plate roof fixture that can be prevented.

前記目的を達成するため、
請求項１に係る折板屋根用取付具は、下方に向けて拡開した断面略コ状の本体部の両脚片に、ボルトを貫通したうえでナットを螺合し、緊締して前記両脚片を近接させ、前記両脚片の下端から内方に向けて突設された当止片が、折板屋根の上面に突設した凸部に挟着して取り付けられる折板屋根用取付具において、前記両脚片は、前記ボルト及びナットの螺合による緊締により、上方に向けて間隔が狭くなるように対向した状態から、略平行な状態へと移行する構造とされ、前記両脚片の一方には、前記ボルトが貫通する貫通穴の周縁に、前記ボルト頭部の少なくとも一つの角部を嵌合可能な嵌合凹部が設けられており、両脚片の前記平行な状態への移行により、前記嵌合凹部に嵌合していたボルト頭部の角部が、嵌合凹部から離脱する構成としたことを特徴とする。 To achieve the purpose,
The folded plate roof mounting tool according to claim 1 is configured such that a bolt is passed through both leg pieces of a substantially U-shaped cross-section of the main body part, which is expanded downward, and a nut is screwed and tightened to tighten the both leg pieces. was close, abutting-stop piece projecting inwardly from the lower end of the legs piece in folded plate roof fixture mounted in sandwiched protrusion projecting from the upper surface of the folded plate roof, The both leg pieces are structured to shift from a state of being opposed so as to be narrowed upward to a substantially parallel state by tightening by tightening of the bolts and nuts. A fitting recess capable of fitting at least one corner of the bolt head is provided at the periphery of the through hole through which the bolt passes, and the fitting is achieved by shifting both the leg pieces to the parallel state. A configuration in which the corner of the bolt head that was fitted in the mating recess is detached from the mating recess. Characterized in that it was.

請求項２に係る折板屋根用取付具は、請求項１において、当止片の先端には、肉厚に形成された挟着部を形成してなる。   According to a second aspect of the present invention, the folded plate roof mounting tool according to the first aspect is formed by forming a sandwiched portion formed thick at the tip of the stopper piece.

本発明によれば、次のような効果がある。   The present invention has the following effects.

請求項１に係る折板屋根用取付具によれば、両脚片の一方には、ボルトが貫通する貫通穴の周縁に、前記ボルト頭部の少なくとも一つの角部を嵌合可能な嵌合凹部を設けているので、前記ボルトとナットを螺合し、緊締すれば、前記両脚片の当止片が折板屋根の上面に突設した凸部を挟着すると同時に、下方に向けて拡開した断面略コ状の両脚片が近接して狭まるため、前記両脚片が略平行な状態となる。   According to the folded plate roof fixture according to claim 1, the fitting recess capable of fitting at least one corner portion of the bolt head to the periphery of the through hole through which the bolt penetrates one of the leg pieces. If the bolts and nuts are screwed together and tightened, the retaining pieces of the two leg pieces sandwich the projecting part protruding from the upper surface of the folded plate roof and at the same time expand downward Since both leg pieces having a substantially U-shaped cross-section are close and narrow, the both leg pieces are in a substantially parallel state.

そして、前記ボルトとナットを螺合した状態を維持しながら、前記嵌合凹部に嵌合していた前記ボルト頭部の角部が、前記嵌合凹部から離脱して、所謂、空回り状態となり、これ以上の前記ボルト又はナットの緊締を規制できる。   And while maintaining the state where the bolt and the nut are screwed together, the corner of the bolt head that was fitted in the fitting recess is detached from the fitting recess, so-called idle state, Further tightening of the bolt or nut can be restricted.

そのため、作業者が誤って前記ボルト又はナットを締め過ぎても、前記ボルト頭部の角部が、前記嵌合凹部から離脱して、所謂、空回り状態となるため、これ以上の前記ボルト又はナットの緊締を確実に規制して、これらボルト又はナットの螺合部分やボルト頭部等を破損することを確実に防止できる。   Therefore, even if an operator mistakenly tightens the bolt or nut accidentally, the corner portion of the bolt head is detached from the fitting recess and becomes a so-called idle state. Therefore, it is possible to reliably prevent the bolts or nuts from being screwed together or the bolt heads from being damaged.

請求項２に係る折板屋根用取付具によれば、当止片の先端には、肉厚に形成された挟着部を形成してなるので、前記当止片を折板屋根の上面に突設したハゼ部、ボルト体等の凸部に挟持して取り付けた際、前記挟着部によって前記ハゼ部、ボルト体等の凸部を更に確実に取り付けできる。   According to the folded plate roof fixture according to claim 2, since the sandwiched portion formed thick is formed at the tip of the retaining piece, the retaining piece is placed on the upper surface of the folded plate roof. When sandwiched and attached to a protruding projecting part such as a goby part or a bolt body, the projecting part such as the gore part or bolt body can be more reliably attached by the clamping part.

Sectional drawing which shows the state which further attached various apparatuses and instruments to the attached folding plate roof fixture A is shown, respectively.

以下、詳説する。   The details will be described below.

本発明の折板屋根用取付具Ａは、下方に向けて拡開した断面略コ状の本体部１の両脚片２に、ボルト３を貫通したうえでナット４を螺合し、緊締して両脚片２を近接させ、両脚片２の下端から内方に向けて突設された当止片５が、折板屋根Ｙの上面に突設したハゼ部Ｃ等の凸部に挟着して取り付けられる折板屋根用取付具において、両脚片２の一方には、ボルト３が貫通する貫通穴２１の周縁に、ボルト頭部３２の少なくとも一つの角部３２ａを嵌合可能な嵌合凹部２１ａを設けたことを特徴とする。 The folded plate roof mounting tool A of the present invention is screwed into the both leg pieces 2 of the main body portion 1 having a substantially U-shaped cross section that is expanded downward and screwed with a nut 4 and tightened. in proximity legs piece 2, the contact-stopping piece 5 which projects toward the lower end of both leg pieces 2 inwardly and sandwiched protrusion goby portion C or the like projecting from the upper surface of the folded plate roof Y In the fitting for folded plate roof to be attached, a fitting recess 21a in which at least one corner 32a of the bolt head 32 can be fitted to the periphery of the through hole 21 through which the bolt 3 penetrates one of the leg pieces 2. Is provided.

ここで、ハゼ部Ｃ等の凸部とは、分割された長尺の折板屋根Ｙを連結する際に、折板屋根Ｙの上面に断面略円状に突出された丸ハゼ型のハゼ部Ｃ等を意味するものであり、本実施例以外の凸部として、例えば、折板屋根Ｙの上面に断面略Ｌ状に突出された角ハゼ等については同様であるため、前記角ハゼ等の説明については省略する。   Here, the convex portion such as the goby portion C is a round goby type goby portion that protrudes in a substantially circular cross section on the upper surface of the folded plate roof Y when connecting the divided long folded plate roof Y. C and the like, and as convex portions other than the present embodiment, for example, the same is true for the square goby that protrudes in a substantially L-shaped cross section on the upper surface of the folded plate roof Y. The explanation is omitted.

本体部１は、金属板又は硬質樹脂板を、下方に向けて拡開した断面略コ状に形成してなり、対向する両脚片２には、ボルト３の軸部３１が貫通可能な貫通孔２１を各々開設してある。 The main body 1 is formed by forming a metal plate or a hard resin plate in a substantially U-shaped cross section that expands downward, and the opposing leg pieces 2 have through-holes through which the shaft portions 31 of the bolts 3 can pass. Oh Ru by opening each of the 21.

又、両脚片２を架設する本体部１の上板１１中央には、剣先ボルト１２等を立設し、後述する各種機器や器具類を取り付け可能にしている。   In addition, a sword bolt 12 or the like is erected at the center of the upper plate 11 of the main body 1 on which both leg pieces 2 are erected, so that various devices and instruments to be described later can be attached.

そして、貫通穴２１の一方には、ボルト頭部３２の角部３２ａを嵌合するために、貫通孔２１に連続して角状に切り欠いた嵌合凹部２１ａを形成している。   Then, in one of the through holes 21, a fitting recess 21 a that is continuously cut out in a square shape is formed in order to fit the corner 32 a of the bolt head 32.

又、両脚片２の下端には、内方に向けて各々当止片５を突設しており、これら当止片５の先端同士には、ハゼ部Ｃが嵌挿する程度の隙間５１を設けている。   Further, at the lower ends of both leg pieces 2, the stopper pieces 5 are projected inwardly, and a gap 51 is provided between the tips of the stopper pieces 5 so as to fit the goby portion C. Provided.

ここで、当止片５の先端によって、ハゼ部Ｃの脚部Ｃ１を挟着するのであるが、当止片５を単に脚部Ｃ１に挟着しただけでは、当止片５を近接させた場合にズレが生じて、脚部Ｃ１を十分に挟持できない恐れもある。   Here, the leg C1 of the goby portion C is clamped by the tip of the stopper piece 5. However, the stopper piece 5 is brought close to the stopper C 5 simply by clamping the stopper piece 5 to the leg C1. In some cases, a deviation may occur, and the leg C1 may not be sufficiently clamped.

そのため、本発明では、更に、当止片５の先端には、リブ、折り返し等によって肉厚に形成された挟着部５２を形成しており、ここでは、当止片５の前、後に亘ってリブを形成して挟着部５２を構成している。   Therefore, in the present invention, a sandwiching portion 52 formed thick by ribs, folding, or the like is further formed at the tip of the stopper piece 5, and here, before and after the stopper piece 5. The sandwiching portion 52 is configured by forming ribs.

このようなリブによる挟着部５２によれば、リブの一般的な効果である当止片５の強化を図ることができるだけでなく、当止片５の先端を肉厚に形成して当止片５をハゼ部Ｃの脚部Ｃ１に挟持して取り付けた際、肉厚の挟着部５２によってハゼ部Ｃの脚部Ｃ１との接触面積が増して更に確実に取り付けできる。   According to the sandwiched portion 52 with such ribs, not only can the reinforcing piece 5, which is a general effect of the ribs, be reinforced, but also the end of the stopper piece 5 is formed thick to stop. When the piece 5 is clamped and attached to the leg portion C1 of the goby portion C, the contact area with the leg portion C1 of the goby portion C is increased by the thick clamping portion 52 and can be more reliably attached.

又、本実施例では、当止片５の先端略中央に、折板屋根Ｙの上面に突設した後述するボルト体Ｂの外周面に嵌合可能な凹所６を形成しており、具体的には、凹所６は、ボルト体Ｂを両側から嵌合するように当止片５の先端中央を半円状に切り欠くか、又は、先端中央を角状に切り欠いて形成している。   Further, in this embodiment, a recess 6 is formed in the substantially center of the front end of the stopper piece 5 and can be fitted to the outer peripheral surface of a bolt body B described later, which protrudes from the upper surface of the folded plate roof Y. Specifically, the recess 6 is formed by cutting the center of the tip of the stopper piece 5 into a semicircular shape so as to fit the bolt body B from both sides, or by cutting the center of the tip into a square shape. Yes.

以上のように構成した本発明の折板屋根用取付具Ａは、以下の要領で折板屋根Ｙに取り付けて使用する。   The folded plate roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

先ず、両脚片２の貫通孔２１の一方からボルト３の軸部３１を貫通したうえで、ボルト３の先端側からナット４を軽く締めて仮止め状態にしたうえで、折板屋根Ｙに立設されたハゼ部Ｃの上方から、両脚片２の隙間５１を通じてハゼ部Ｃを嵌挿する。この状態の両脚片２は、上方に向けて狭くなるように対向しており、略台形の側辺に貫通穴２１が貫通するようになる〔図２（ａ），（ｂ）、参照。〕。   First, after passing through the shaft portion 31 of the bolt 3 from one of the through holes 21 of the both leg pieces 2, the nut 4 is lightly tightened from the front end side of the bolt 3 to be in a temporarily fixed state, and then standing on the folded plate roof Y. The goby portion C is inserted through the gap 51 between the leg pieces 2 from above the gouge portion C provided. The two leg pieces 2 in this state face each other so as to become narrower upward, and the through hole 21 penetrates the substantially trapezoidal side (see FIGS. 2A and 2B). ].

次に、仮止め状態にしていたボルト３及びナット４を緊締すると、この締め付け力によって両脚片２が近接して、両脚片２下端の当止片５も互いに近接し、この当止片５に設けた挟着部５２が、ハゼ部Ｃの脚部Ｃ１を挟持する。もっとも、本実施例では、当止片５の先端を肉厚に形成して挟着部５２を形成しているため、この挟着部５２先端が脚部Ｃ１に各々挟着する。   Next, when the bolt 3 and the nut 4 that have been temporarily fixed are tightened, both the leg pieces 2 are brought close to each other by the tightening force, and the stopper pieces 5 at the lower ends of the both leg pieces 2 are also close to each other. The provided clamping part 52 clamps the leg part C1 of the goby part C. However, in the present embodiment, since the tip of the stopper piece 5 is formed thick to form the sandwiching portion 52, the tip of the sandwiching portion 52 is sandwiched between the leg portions C1.

そして、ボルト３及びナット４を更に緊締すると、この締め付け力によって両脚片２が更に近接する。両脚片２は、上方に向けて間隔が狭くなるように対向していた（略台形）のが、徐々に平行に近づき、やがて、両脚片２が平行な状態となり、ボルト３と両脚片２の接する面も平行な状態となる。 When the bolt 3 and the nut 4 are further tightened, the both leg pieces 2 are further brought closer by this tightening force. The two leg pieces 2 face each other so that the distance between them is narrower toward the upper side (substantially trapezoidal), but gradually approaches to be parallel, and eventually the two leg pieces 2 become parallel, and the bolt 3 and the two leg pieces 2 The contacting surface is also parallel.

このとき、嵌合凹部２１ａに嵌合していたボルト頭部３２の角部３２ａが、嵌合凹部２１ａから離脱して、所謂、空回り状態となり、これ以上のボルト３又はナット２の緊締を規制すると共に、当止片５にて脚部Ｃ１を強固に挟持して本体部１をハゼ部Ｃの脚部Ｃ１に取り付けできる〔図３（ｃ）、参照。〕。   At this time, the corner portion 32a of the bolt head portion 32 fitted in the fitting recess 21a is detached from the fitting recess 21a, and is in a so-called idle state, and further tightening of the bolt 3 or the nut 2 is restricted. In addition, the leg portion C1 can be firmly clamped by the stopper piece 5 to attach the main body 1 to the leg portion C1 of the goby portion C [see FIG. 3 (c). ].

最後に、この取り付けた折板屋根用取付具Ａの本体部１の上板１１に立設された剣先ボルト１２等に、従来同様にして各種機器や器具類Ｄ等を取り付けて施工を完了するのである〔図３（ｄ）、参照。〕。   Finally, various equipment and instruments D are attached to the sword bolt 12 standing on the upper plate 11 of the main body portion 1 of the attached folded-roof roof mounting tool A in the same manner as in the past to complete the construction. [Refer to FIG. 3 (d). ].

このように、本発明に係る折板屋根用取付具Ａによれば、作業者が誤ってボルト３又はナット２を締め過ぎても、ボルト頭部３２の角部３２ａが、嵌合凹部２１ａから離脱して、所謂、空回り状態となるため、これ以上のボルト３又はナット４の緊締を確実に規制して、これら本体部１の両脚片２及び当止片５の変形、並びに、ボルト３又はナット４の螺合部分やボルト頭部等を破損することを確実に防止できる。   Thus, according to the folded plate roof fixture A according to the present invention, even if the operator accidentally overtightens the bolt 3 or the nut 2, the corner portion 32 a of the bolt head portion 32 is removed from the fitting recess 21 a. Since it is separated and becomes a so-called idle state, further tightening of the bolt 3 or the nut 4 is surely restricted, the deformation of both the leg pieces 2 and the stopper pieces 5 of the main body 1 and the bolt 3 or It is possible to reliably prevent the screwed portion of the nut 4 and the bolt head from being damaged.

図４は、本発明に係る折板屋根用取付具Ａの他の実施例を示す分解斜視図であり、図５（ａ），（ｂ）及び図６（ｃ），（ｄ）は、図４で示した折板屋根用取付具Ａの施工状態を示す断面図である。   FIG. 4 is an exploded perspective view showing another embodiment of the folded-plate roof fixture A according to the present invention, and FIGS. 5 (a), 5 (b) and 6 (c), 6 (d) are diagrams. It is sectional drawing which shows the construction state of the fixture A for folded-plate roof shown by 4. FIG.

なお、図５（ａ）は、折板屋根用取付具Ａを折板屋根に取り付ける前の状態を示す断面図、図５（ｂ）は、折板屋根用取付具Ａを折板屋根のボルト体Ｂに嵌挿した状態を示す断面図、図６（ｃ）は、折板屋根用取付具Ａを折板屋根のボルト体Ｂに取り付けた状態を示す断面図、図６（ｄ）は、取り付けた折板屋根用取付具Ａに各種機器や器具類を更に取り付けた状態を示す断面図を各々示している。   5A is a cross-sectional view showing a state before the folded plate roof fixture A is attached to the folded plate roof, and FIG. 5B is a bolt of the folded plate roof. FIG. 6C is a cross-sectional view showing a state where the folded plate roof fixture A is attached to the bolt body B of the folded plate roof, and FIG. Sectional drawing which shows the state which further attached various apparatuses and instruments to the attached folding plate roof fixture A is shown, respectively.

ここで、図１〜図３と共通する部位には、同一の符号を付して、重複する説明を省略し、以下では、本実施例の特徴についてのみ説明する。 Here, parts common to FIGS. 1 to 3 are denoted by the same reference numerals, and redundant description is omitted. Only the features of the present embodiment will be described below.

すなわち、本実施例では、折板屋根Ｙの連結構造が、図１〜図３で示したようなハゼ部Ｂではなく、隣接する折板屋根Ｙの山部同士を重合したうえで、その適所に下方から剣先ボルト等のボルト体Ｂを貫通すると共に、このボルト体Ｂにナットを螺合して、分割された長尺の折板屋根Ｙを幅方向に連結してなる構造（以下、「重ね式構造」と呼ぶ。）に対して、図１〜図３で示した折板屋根用取付具Ａを用いる場合について説明している。   That is, in this embodiment, the connection structure of the folded plate roof Y is not the gore portion B as shown in FIGS. And a bolt body B such as a sword bolt from below, and a nut is screwed into the bolt body B to connect the divided long folded plate roof Y in the width direction (hereinafter referred to as “ The case where the folded plate roof fixture A shown in FIGS. 1 to 3 is used is described.

具体的には、本発明の折板屋根用取付具Ａをボルト体Ｂに取り付ける場合には、当止片５の先端ではなく、当止片５の先端略中央に形成した凹所６を、ボルト体Ｂの外周面に嵌合させて取り付けることとなる。   Specifically, when attaching the folded plate roof fixture A of the present invention to the bolt body B, not the tip of the stopper piece 5, but the recess 6 formed at the approximate center of the tip of the stopper piece 5, The bolt body B is fitted and attached to the outer peripheral surface.

ここで、凹所６として、当止片５の先端中央を半円状や角状に切り欠いて形成しただけでは、当止片５を近接させた場合にボルト体Ｂを十分に挟持できない恐れもある。   Here, if the stopper 6 is simply formed by cutting the center of the tip of the stopper piece 5 into a semicircular shape or a square shape, the bolt body B may not be sufficiently clamped when the stopper piece 5 is brought close to the recess 6. There is also.

そのため、本実施例では、凹所６に、ボルト体Ｂのネジ溝Ｂ１に食い込んで係止可能な切り起し片６１を複数形成してなる。   Therefore, in this embodiment, a plurality of cut-and-raised pieces 61 that can be engaged with and locked into the thread groove B1 of the bolt body B are formed in the recess 6.

具体的には、図４中の破線で囲んだ凹所６の拡大平面図に示すように、凹所６の中央部分に２条の切込溝６１ａを形成し、この切込溝６１ａに挟まれた片を上方に起立させて１つの起り起し片６１を形成すると共に、起立されていない凹所６の内縁部分を他の切り起し片６１として、複数の切り起し片６１を形成している。   Specifically, as shown in the enlarged plan view of the recess 6 surrounded by a broken line in FIG. 4, two slits 61a are formed in the central portion of the recess 6, and are sandwiched between the slits 61a. The raised piece is raised upward to form one raised piece 61, and the inner edge portion of the recess 6 not raised is used as another raised piece 61 to form a plurality of raised pieces 61 is doing.

このような複数の切り起し片６１を凹所６に形成することで、凹所６をボルト体Ｂの外周面に嵌合して取り付けた際、複数の切り起し片６１がボルト体Ｂのネジ溝Ｂ１の異なる位置に各々係止して強固に挟持でき、更に、当止片５を近接させた場合に複数の切り起し片６１がボルト体Ｂを下方に押圧する作用を生じるために、凹所６及び切り起し片６１によってボルト体Ｂを更に確実に取り付けできる。   By forming such a plurality of cut-and-raised pieces 61 in the recess 6, when the recess 6 is fitted and attached to the outer peripheral surface of the bolt body B, the plurality of cut-and-raised pieces 61 become the bolt body B. Since the plurality of cut and raised pieces 61 press the bolt body B downward when the stopper pieces 5 are brought close to each other, the screw grooves B1 can be firmly clamped at different positions. In addition, the bolt body B can be more reliably attached by the recess 6 and the cut and raised piece 61.

以上のように構成した本発明の折板屋根用取付具Ａは、以下の要領で折板屋根Ｙに取り付けて使用する。   The folded plate roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

先ず、両脚片２の貫通穴２１の一方からボルト３の軸部３１を貫通したうえで、ボルト３の先端側からナット４を軽く締めて仮止め状態にしたうえで、折板屋根Ｙに立設されたボルト体Ｂの上方から、両脚片２の隙間５１を通じてボルト体Ｂを嵌挿する〔図５（ａ），（ｂ）、参照。〕。   First, after passing through the shaft portion 31 of the bolt 3 from one of the through holes 21 of the both leg pieces 2, the nut 4 is lightly tightened from the front end side of the bolt 3 to be in a temporarily fixed state, and then it stands on the folded plate roof Y. The bolt body B is fitted and inserted through the gap 51 between the leg pieces 2 from above the installed bolt body B (see FIGS. 5A and 5B). ].

次に、仮止め状態にしていたボルト３及びナット４を緊締すると、この締め付け力によって両脚片２が近接して、両脚片２下端の当止片５も互いに近接し、この当止片５に設けた凹所６がボルト体Ｂの外周面に嵌合してボルト体Ｂを挟持する。もっとも、本実施例では、ボルト体Ｂのネジ溝Ｂ１に食い込んで係止可能な複数の切り起し片６１を形成しているため、本実施例の場合では、複数の切り起し片６１がボルト体Ｂのネジ溝Ｂ１に各々食い込んで、ボルト体Ｂを複数の位置で挟持する。   Next, when the bolt 3 and the nut 4 that have been temporarily fixed are tightened, both the leg pieces 2 are brought close to each other by the tightening force, and the stopper pieces 5 at the lower ends of the both leg pieces 2 are also close to each other. The provided recess 6 is fitted to the outer peripheral surface of the bolt body B to sandwich the bolt body B. However, in the present embodiment, a plurality of cut and raised pieces 61 that can be engaged and locked into the thread groove B1 of the bolt body B are formed. Each bolt groove B1 of the bolt body B is bitten and the bolt body B is clamped at a plurality of positions.

そして、ボルト３及びナット４を更に緊締すると、この締め付け力によって両脚片２が更に近接して、やがて、両脚片２が平行な状態となるが、このとき、嵌合凹部２１ａに嵌合していたボルト頭部３２の角部３２ａが、嵌合凹部２１ａから離脱して、所謂、空回り状態となり、これ以上のボルト３又はナット４の緊締を規制すると共に、凹所６がボルト体Ｂの外周面に嵌合し、複数の切り起し片６１がボルト体Ｂのネジ溝Ｂ１に各々食い込んで、ボルト体Ｂを強固に挟持して確実に取り付けできる〔図６（ｃ）、参照。〕。   When the bolt 3 and the nut 4 are further tightened, the two leg pieces 2 are brought closer to each other by the tightening force, and eventually the two leg pieces 2 are in a parallel state. The corner 32a of the bolt head 32 is detached from the fitting recess 21a, so that it is in a so-called idle state, and further tightening of the bolt 3 or nut 4 is restricted, and the recess 6 is the outer periphery of the bolt body B. The plurality of cut-and-raised pieces 61 can be fitted into the surface and bite into the thread grooves B1 of the bolt body B, so that the bolt body B can be firmly clamped and attached securely [see FIG. 6 (c). ].

最後に、この取り付けた折板屋根用取付具Ａの本体部１の上板１１に立設された剣先ボルト１２等に、従来同様にして各種機器や器具類Ｄを取り付けて施工を完了するのである〔図６（ｄ）、参照。〕。   Finally, since various devices and instruments D are attached to the sword tip bolts 12 and the like standing on the upper plate 11 of the main body 1 of the attached folding plate roof fixture A in the same manner as before, the construction is completed. Yes [see FIG. 6 (d). ].

このように、本発明に係る折板屋根用取付具Ａによれば、作業者が誤ってボルト３又はナット２を締め過ぎても、ボルト頭部３２の角部３２ａが、嵌合凹部２１ａから離脱して、所謂、空回り状態となるため、これ以上のボルト３又はナット４の緊締を確実に規制して、これら本体部１の両脚片２及び当止片５の変形、並びに、ボルト体Ｂのネジ溝Ｂ１、及び、ボルト３又はナット４の螺合部分やボルト頭部等を破損することを確実に防止できる。   Thus, according to the folded plate roof fixture A according to the present invention, even if the operator accidentally overtightens the bolt 3 or the nut 2, the corner portion 32 a of the bolt head portion 32 is removed from the fitting recess 21 a. Since it is separated and becomes a so-called idle state, further tightening of the bolt 3 or the nut 4 is surely restricted, the deformation of both the leg pieces 2 and the stopper pieces 5 of the main body 1, and the bolt body B It is possible to reliably prevent the thread groove B1 and the screwed portion of the bolt 3 or the nut 4 or the bolt head from being damaged.
