Description

【0001】
【発明の属する技術分野】
本発明は、複数の支持板を、平行して配設された複数のねじ棒に支持する場合に用いられる複合ナット及び複合ナットを用いた支持板の支持方法に関する。
【0002】
【従来の技術】
従来の複合ナットは、例えば、実公昭第50−37489号に示すように、平面視六角形状のナット本体と、該ナット本体の側面及び上面を被覆する被冠体とを備えている。ナット本体は、二つに分割されたナット片が接合されて形成されている。該ナット本体の側面には、ナット本体の径方向に嵌入穴が掘穿され、該嵌入穴には、ばねが挿入されると共に、該ばねによって付勢されたボールが出退可能に設けられている。被冠体には、ナット本体が螺合するねじ棒に挿通する挿通穴と、ノット本体の側面を被覆する側面被覆部と、ナット本体の上面を被覆する上面被覆部と、内周面に形成された挿通穴よりも大径の嵌合凹部と、該嵌合凹部の内周面に形成された環状溝とを具備している。そして、嵌合凹部と挿通穴とが連通し、嵌合凹部と挿通穴との段差部によってナット本体との嵌脱が可能になる。
【0003】
そして、片方のナット片のねじ溝を当接すると共に、別方のナット片のねじ溝を当接し、両ナット片の互いの接合面を接合し、ナット本体を形成する片方、被冠体の挿通穴を介してねじ棒の上方から被冠体を挿通した後、被冠体をナット本体の上方から被せて、被冠体の側面被覆部によってナット本体の各側面を覆うと共に、被冠体の上面被覆部によってナット本体の上面を覆い、さらに、被冠体の嵌合凹部に形成された環状溝を、ナット本体から進退可能なボールに係止させて、被覆体とナット本体とを一体化して複合ナットを組立て、複合ナットを工具によって緊締する。
【0004】
さらに、他の従来の複合ナットは、例えば、特開平第5−180210号に示すように、六角ナットと略同一形状を呈したナット本体を備えており、該ナット本体は、対向する頂点を通る中心線に沿って二つに分割されたナット片が接合されて形成されている。片方のナット片の接合面には、上部、中央部、下部にそれぞれ係止爪が突設されている。別方のナット片の接合面には、各係止片が係脱する係止ブロックが設けられている。
【0005】
そして、片方のナット片のねじ溝を当接すると共に、別方のナット片のねじ溝を当接し、片方のナット片の各係止爪を、別方のナット片の係止ブロックに係止し、ナット本体を形成して、ナット本体を工具によって緊締する。
【0006】
【発明が解決しようとする課題】
しかしながら、従来の複合ナットの場合、前者においては、ナット本体の上方から被冠体を被せて両ナット片を一体にしてナット本体を形成するようにしているため、ねじ棒の両端部に螺合させるには適しているが、ねじ棒の所望の位置でナット本体を形成し、被冠体を上方から被せて一体化して複合ナットを形成するには不向きであるという問題がある。
【0007】
しかも、ナット本体の側面において、ばねに付勢されたボールを進退可能に設けると共に、被冠体の内周面にボールを係止する環状溝に形成する必要があるため、製造コストが高くなるという問題がある。
【0008】
後者においては、片方のナット片の接合端面に突設する係止片、及び、別方の接合端面に形成される係止ブロックの形状が複雑であり、前者と同様に、その分製造コストが高くなるという問題がある。
【0009】
そこで、本発明は上記問題点に鑑み、簡単な構造で、分割されたナット片によるナット本体の形成維持を確保でき、安価な複合ナット及び複合ナットを用いた支持板の支持方法を提供することを目的とする。
【0010】
【課題を解決するための手段】
上記課題を解決するために、本発明の複合ナットは、請求項1に示す如く、分割されたナット片が接合されて形成されたナット本体と、少なくともナット本体の側面を被覆して両ナット片の接合状態を維持する被冠体とを備えた複合ナットにおいて、ナット片は、接合によって六角ナットと略同一形状のナット本体を形成し、且つ、該ナット本体の対向する頂点を通る中心線に沿って二分割された形状を呈し、しかも、ナット片の片側の接合面にはV字形状の凹部が形設され、さらに、ナット片の別側の接合面に前記V字形状の凹部と略同一形状で前記凹部に接離可能な凸が形設され、
また、前記中心線に対して直交する位置のナット本体の両側面の少なくともいずれか一方には、ナット本体の軸線に平行して二つの係止溝が形成され、
両ナット片の接合部位を抱持する被冠体は、ナット本体の側面を被覆する側面被覆部と、ナット本体の上面を被覆する上面被覆部とを有し、さらに、ナット本体の螺合するねじ棒の側方から被冠体の挿脱が可能になるように、被冠体の側面被覆部の一面から上面被覆部にかけて挿通穴が穿設され、加えて、前記係止溝に係脱可能な係止片が被冠体の側面被覆部の挿通穴の開口端部、又は、側面被覆部の内側面の少なくともいずれか一方に形成されてなるものである。
【0011】
したがって、従来に比して簡単な構造で分割されたナット片を接合できるようになる。しかも、ナット片の接合面に形成されたV字形状の凹部及び凸部は、容易に加工できるため、加工費を低減することができる。さらに、複合ナットの外形が平面視四角形状や六角形状のいずれであっても対応できる。
【0013】
一般に、六角ナットを締め付けた場合、六角ナットの各角部に最も大きな締め付け力が作用することになる。よって、対向する頂点を通る中心線に沿ってナット本体を二分割し、片方のナット片の片側の接合面の両端部に突起を形成して凹部を形設すると共に、ナット片の別側の接合面の両端部を切削して凸部を形設すれば、頂点部位にかかる大きな力を利用することで、二分割された両ナット片の接合状態が維持されることになる。
【0014】
しかも、被冠体の側面被覆部の一面から上面被覆部にかけて挿通穴を穿設するようにしたので、ねじ棒の側方から被冠体を挿通できるようになり、ねじ棒の端部から螺合させる必要がなく、作業時間の短縮が図れる。また、被冠体の上面被覆部によって、ナット本体の上面が被覆されると共に、側面被覆部によってナット本体の側面が被覆されることになり、両ナット片の接合状態が維持されることになる。
【0015】
さらに、被冠体の被覆によって、ナット本体の接合状態が保持できるように、例えば、被冠体の側面被覆部の開口端部の両側、又は、側面被覆部の内側面の少なくともいずれか一方に係止片を形成すると共に、前記中心線に対して直交する位置のナット本体の両側面の少なくともいずれか一方に係止溝を形成するようにすれば、被冠体の側面被覆部の係止によって、両ナット片が抱持されるようになり、ナット本体の頂点部位の接合と、被冠体のナット本体への係止との相乗効果によって、ナット本体の頂点部位における接合状態の保持が充分に強化されることになり、外部からの力に対して接合されたナット片が容易に離脱することがなく、複合ナットの締め付け強度が確保される。
【0016】
さらに請求項に示す如く、二分割されたナット片のいずれか片方のナット片のV字形状の凹部が形設された側の接合端部と、別方のナット片の前記V字形状の凹部と略同一形状で前記凹部に接離可能な凸部が形設された側の接合端部とを回動可能に連結するのが好ましい。
【0017】
そうすれば、分割された二つのナット片を個別にねじ棒に当接することもなく、しかも、両ナット片の接合面の接合状態を指先で維持させる必要もなく、連結された両ナット片をねじ棒の周面を覆うようして両ナット片の接合面を接合するだけでナット本体を簡単に形成できる。
【0018】
また、請求項に示す如く、接合によって六角ナットと略同一形状のナット本体を形成し、且つ、該ナット本体の対向する頂点を通る中心線に沿って二分割された形状を呈するナット片の片側の接合面にはV字形状の凹部が形設され、さらに、ナット片の別側の接合面には前記V字形状の凹部と略同一形状の凸部が形設された二つのナット片の接合によって形成されるナット本体と、少なくともナット本体の側面を被覆すると共に、ナット本体の側面に係止し、且つ、ナット本体が螺合するねじ棒の側方から挿脱可能な被冠体とを備えた複合ナットと六角ナットを用いて、複数の支持板を、平行して配設された複数のねじ棒に支持する、複合ナットを用いた支持板の支持方法であって、六角ナットを各ねじ棒に予め螺合させておき、支持板の片面を各ねじ棒に挿通して各六角ナットに当接し、各ねじ棒と支持板とが略直交するように六角ナットの位置を微調整し、つぎに、支持板の別面において、二分割された複合ナットの片方のナット片のねじ溝をねじ棒に当接すると共に、別方のナット片のねじ溝をねじ棒に当接し、さらに、両ナット片を接合させて六角ナットと略同一形状のナット本体を形成し、
続いて、被冠体をねじ棒の側方から挿入し、さらに、被冠体によって少なくともナット本体の側面を被覆すると共に、被冠体の係止片をナット本体の側面の係止溝に係止させて両ナット片の接合状態を維持し、被冠体とナット本体とを一体化してねじ棒に螺合した状態の複合ナットを組立て、その後、複合ナット及び六角ナットを緊締して支持板を挟持するようにしたものである。
【0019】
よって、複数の支持板をねじ棒に予め螺合させた六角ナットによって位置決めできる。さらに、ねじ棒の側方からねじ棒に当接させたナット本体、及び、ねじ棒の側方から挿通させた被冠体によって、六角ナットの反対側に複合ナットを容易に且つ迅速に組み立てることができる。このため、平行して配設されたねじ棒に短時間で複数の支持板を容易に支持できるようになる。
【0020】
したがって、複数の支持板が支持されるラックの組立作業、あるいは、電気工事や水道工事において、複数の支持板によって支持される管体の配管工事の作業効率が大幅に改善される。
【0021】
【発明の実施の形態】
本発明の一実施形態につき、図1〜図4を参照して説明する。
本発明の複合ナットNは、二分割されたナット片1,2と、該両ナット片1,2が接合されて形成されたナット本体3と、該ナット本体3に嵌脱可能に構成されたナット本体3と略同一形状の被冠体10とから構成されている。
【0022】
ナット片1、2は、対向する頂点を通る中心線に沿って二分割されており、ナット片1、2の片側の接合面の両端部に形成された突起によってV字形状の凹部1a、2aが形設されると共に、ナット片1、2の別側の接合面の両端部を切削することによって前記V字形状の凹部と略同一形状で前記凹部に接離可能な凸部1b、2bが形設されている。そして、ナット本体3は、両ナット片1、2が接合されて六角ナット17と略同一形状を形成することになり、ねじ穴5も有することになる。さらに、前記中心線に対して直交する位置のナット本体3の両側面の少なくともいずれか一方には、ナット本体3の軸線方向に対して平行するように二つの係止溝4、4が形成されている。
【0023】
被冠体10は、ナット本体3が螺合するねじ棒15の挿通穴11と、ナット本体3の側面を覆う側面被覆部12と、ナット本体3の上面の両側を覆う平面視二等辺三角形状の上面被覆部13とを有している。さらに、挿通穴11は、被冠体10の側面被覆部12の一面から上面被覆部13にかけて断面L字形状に穿設され、ナット本体3の螺合するねじ棒15の側方からの挿脱が可能になる。加えて、被冠体10の側面被覆部12の開口端部の両側には、内側に折り曲げられた係止片14,14が形成されており、ナット本体3の係止溝4,4に係止することで、両ナット片1,2の接合状態が被冠体10の被覆によって保持されている。そして、二つの上面被覆部13は、被冠体10の補強の役目と、側面被覆部12の係止状態の補強の役目とを担っている。
【0024】
つぎに本発明の複合ナットNの使用態様について図4(A)〜(C)を参照して説明する。平行して配設された複数のねじ棒15,…に、六角ナット17,…の平坦な底面を上側にして予め螺合させておき、支持板16,…を各ねじ棒15,…に挿通すると共に、支持板16,…の片面を各六角ナット17,…に当接し、各ねじ棒15,…と支持板16,…とが略直交するように六角ナット17,…の位置を微調整する。
【0025】
つぎに、支持板16,…の別面において、二分割された複合ナットNの片方のナット片1のねじ溝をねじ棒15に当接すると共に、別方のナット片2のねじ溝をねじ棒15に当接し、さらに、片方のナット片1のV字形状の凹部1aと別方のナット片2の部2bを、また、片方のナット片1の凸部1bと別方のナット片2のV字形状の凹部2aを接合させて六角ナット17と略同一形状のナット本体3を形成する。
【0026】
よって、ナット本体3を工具で締め付けた場合、ナット本体3の各角部にかかる大きな締め付け力が加わることになるため、この力を利用することで、二分割された両ナット片1,2の接合状態が維持できることになる。
【0027】
続いて、被冠体10の側面被覆部12から上面被覆部13にかけて穿設された挿通穴11を介して、被冠体10をねじ棒15の側方から挿通すると共に、ナット本体3の上方から被冠体10を被せる。この場合、ねじ棒15の側方から被冠体10を挿通しているため、ナット本体3に簡単且つ迅速に被せることができる。
【0028】
さらに、被冠体10の側面被覆部12によってナット本体3の各側面を覆うと共に、被冠体10の上面被覆部13によってナット本体3の上面を覆う。加えて、両ナット片1,2の接合状態を保持すべく、側面被覆部12の挿通穴11の開口端部の両側に形成された係止片14,14を、ナット本体3の側面に形成された係止溝4,4に係止させ、被冠体10とナット本体3とを一体化してねじ棒に螺合した状態の複合ナットNを組立てる。この際、側面被覆部12によるナット本体3の側面被覆が、上面被覆部13によって補強されることになり、両ナット片1,2の接合状態がより一層強化されることになる。
【0029】
その後、複合ナットN及び六角ナット17を緊締して、支持板16の両面に六角ナット17,…及び複合ナットNの底面を圧接し、支持板16の両面を複合ナットN及び六角ナット17,…で挟持する。
【0030】
このように、被冠体10の側面被覆部12の係止によって、両ナット片1,2が抱持されるようになり、ナット本体3の頂点部位の接合と、被冠体10のナット本体3への係止との相乗効果によって、ナット本体3の頂点部位における接合状態の保持が充分に強化されることになり、外部からの力に対して接合されたナット片1,2が容易に離脱することがなく、複合ナットNの締め付け強度が確保される。
【0031】
なお、前記実施形態の場合、被冠体10の挿通穴11の開口端部に係止片14,14を形成するようにしたが、係止片14,14を被冠体10の側面被覆部12の内側面にも形成するようにしてもよい(図示せず)。この場合、被冠体10の挿通穴11の係止片14,14が、ナット本体3の片方の係止溝4,4に係止すると共に、被冠体10の内側面の係止片14,14が、ナット本体3の別方の係止溝4,4に係止するため、ナット片1,2の接合状態がより一層強化されると共に、締め付けの際にもナット片1,2の接合状態が強固に維持される。また、図3に示すように、被冠体10を二分割し、片側の被冠体10aの側面被覆部12aの両端部に係止片14a,14aを形成すると共に、別側の被冠体10bの側面被覆部12bの両端部に係止片14b,14bを形成するようにしてもよい。この場合、挿通穴11は不要になり、ナット本体3を側方からより簡単に被覆できる。
【0032】
さらに、前記実施形態の場合、分割されたナット片1,2を使用したが、図6〜図8に示すように、片方のナット片1の片側の接合端部と、別方のナット片2の別側の接合端部を断面C字形状の連結部材18によって回動可能に連結するようにしてもよい。この場合、二つのナット片1,2が連結されることで、両ナット片1,2のねじ溝をねじ棒15に当接しやすくなり、ナット片1,2をねじ棒15にセッティングする作業がより簡単になり、組立て作業の効率化が図れる。
【0033】
また、分割されたナット片1,2によって形成されるナット本体3の形状を、六角ナット17と略同一形状としたが、四角ナットとしてもよい。そして、二分割されたナット片1,2としたが、二つ以上に分割するようにしてもよい。
【0035】
加えて、支持板16,…は、ラックに用いられるもの、配管作業に用いられるものいずれであってもよい。
【0036】
【発明の効果】
以上説明したように、本発明の複合ナットによれば、V字形状の凹部を、分割されたナット片の片側の接合面に形成すると共に、前記凹部に接離可能に接合する凸部をナット片の別側の接合面に形成し、被冠体の側面被覆部及び上面被覆部によって、ナット本体の側面を覆うと共に、ナット本体の上面を覆うようにしたので、簡単な構造で容易に接合できる効果がある。
【0037】
また、六角ナットと略同一形状のナット本体をナット片の接合によって形成すべく、該ナット片の形状を、ナット本体の対向する頂点を通る中心線に沿って二分割し、ナット片の片側の接合面の両端部に形成された突起によってV字形状の凹部を形設すると共に、ナット片の別側の接合面の両端部を切削することによって凸部を形設したため、外部からの締め付け力が加わっても、接合状態を有効に維持できる。
【0038】
被冠体の側面被覆部の一面から上面被覆部にかけて穿設された挿通穴によって、ねじ棒の側方から被冠体の挿脱が可能になり、作業効率が向上する。さらに、被冠体の側面被覆部の係止片を、ナット本体の側面の係止溝に係止するようにしたので、ナット本体の接合状態を被冠体の被覆によって保持できる。
【0039】
さらに、片方のナット片の片側の接合端部と、別方のナット片の別側の接合端部とを回動可能に連結すれば、より一層作業性がよくなる。

BACKGROUND OF THE INVENTION
The present invention relates to a composite nut used when a plurality of support plates are supported by a plurality of screw rods arranged in parallel, and a support plate support method using the composite nut.
[0002]
[Prior art]
As shown in, for example, Japanese Utility Model Publication No. 50-37489, a conventional composite nut includes a nut body having a hexagonal shape in plan view, and a crown body that covers the side surface and the upper surface of the nut body. The nut body is formed by joining nut pieces divided into two. A fitting hole is formed in the side surface of the nut body in the radial direction of the nut body, and a spring is inserted into the fitting hole so that a ball urged by the spring can be withdrawn and retracted. Yes. Formed on the inner peripheral surface of the body to be crowned is an insertion hole that passes through a screw rod into which the nut body is screwed, a side surface covering portion that covers the side surface of the knot body, an upper surface covering portion that covers the upper surface of the nut body. A fitting recess having a diameter larger than that of the inserted through hole, and an annular groove formed on the inner peripheral surface of the fitting recess. Then, the fitting recess and the insertion hole communicate with each other, and the nut main body can be fitted and removed by the stepped portion between the fitting recess and the insertion hole.
[0003]
Then, while abutting the thread groove of one nut piece, abutting the thread groove of the other nut piece, joining the joint surfaces of both nut pieces to each other, forming the nut body, inserting the crown body After inserting the crown body from above the screw rod through the hole, the crown body is covered from above the nut body, and each side surface of the nut body is covered by the side surface covering portion of the crown body, The top cover covers the top surface of the nut body, and the annular groove formed in the fitting recess of the crown body is locked to a ball that can be advanced and retracted from the nut body, so that the cover body and the nut body are integrated. Assemble the composite nut and tighten the composite nut with a tool.
[0004]
Furthermore, another conventional composite nut includes a nut body having substantially the same shape as a hexagonal nut, as shown in, for example, Japanese Patent Laid-Open No. 5-180210, and the nut body passes through opposing vertices. A nut piece divided into two along the center line is joined and formed. On the joint surface of one nut piece, a locking claw is projected from the upper part, the central part, and the lower part. On the joint surface of the other nut piece, there is provided a locking block for engaging and disengaging each locking piece.
[0005]
Then, the thread groove of one nut piece is abutted and the thread groove of the other nut piece is abutted, and each locking claw of one nut piece is locked to the locking block of the other nut piece. The nut body is formed, and the nut body is tightened with a tool.
[0006]
[Problems to be solved by the invention]
However, in the case of the conventional compound nut, in the former case, the nut body is formed by covering the crown body from above the nut body, so that the nut body is formed integrally. However, it is unsuitable for forming a nut main body at a desired position of the screw rod and covering the crown body from above to form a composite nut.
[0007]
In addition, on the side surface of the nut body, it is necessary to provide the ball biased by the spring so as to be able to advance and retreat, and it is necessary to form an annular groove for locking the ball on the inner peripheral surface of the crowned body, which increases the manufacturing cost. There is a problem.
[0008]
In the latter, the shape of the locking piece protruding from the joint end face of one nut piece and the lock block formed on the other joint end face are complicated, and the manufacturing cost is correspondingly the same as the former. There is a problem of becoming higher.
[0009]
Therefore, in view of the above problems, the present invention provides an inexpensive composite nut and a support method for a support plate using the composite nut that can ensure the formation and maintenance of the nut body by the divided nut pieces with a simple structure. With the goal.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a composite nut according to the present invention comprises a nut body formed by joining divided nut pieces and at least a side surface of the nut body so as to cover both nut pieces. In the composite nut including the crown body that maintains the joined state of the nut body , the nut piece forms a nut body having substantially the same shape as the hexagon nut by joining, and a center line passing through the opposite vertex of the nut body. along the shape of a bisected shape, moreover, the bonding surface of one side of the nut pieces are Katachi設recess of V-shaped, and further, and the joint surface of another side of the nut piece recess of the V-shaped A convex part that is substantially the same shape and can be contacted and separated from the concave part is formed,
Moreover, two locking grooves are formed in parallel to the axis of the nut body on at least one of both side surfaces of the nut body at a position perpendicular to the center line ,
The crown body that holds the joint portion of both nut pieces has a side surface covering portion that covers the side surface of the nut body, and an upper surface covering portion that covers the upper surface of the nut body, and is further screwed into the nut body. An insertion hole is drilled from one side of the side cover of the crown body to the top cover so that the crown body can be inserted and removed from the side of the screw rod. open end of the insertion hole of such locking piece side surface covering portion of the crown, or is made by made form in at least one of the inner surfaces of the side surface covering portion.
[0011]
Thus, a simple structure as compared with the conventional, it becomes possible to join the split nut pieces. And since the V-shaped recessed part and convex part which were formed in the joint surface of a nut piece can be processed easily, processing cost can be reduced. Furthermore, it is possible to cope with the outer shape of the composite nut having a square shape or a hexagonal shape in plan view.
[0013]
Generally, when a hex nut is tightened, the largest tightening force is applied to each corner of the hex nut. Therefore, the nut body is divided into two along the center line passing through the opposite apex, and protrusions are formed on both ends of the joint surface on one side of one nut piece to form a recess, and on the other side of the nut piece If both ends of the joint surface are cut to form the convex portion, the joint state of the two nut pieces divided into two parts is maintained by using a large force applied to the apex portion.
[0014]
In addition, since the insertion hole is formed from one side of the side surface covering portion of the crown body to the upper surface covering portion, the crown body can be inserted from the side of the screw rod, and the screw rod can be inserted from the end of the screw rod. There is no need to match, and the working time can be shortened. Further, the upper surface of the nut body is covered with the upper surface covering portion of the crowned body, and the side surface of the nut body is covered with the side surface covering portion, so that the joined state of both nut pieces is maintained. .
[0015]
