Description

【0001】
【発明の属する技術分野】
本発明は、取付対称の板状をした部分に穿孔される取付孔にナットをかしめて取付けるためのナットのかしめ方法に関するものである。
【0002】
【従来の技術】
従来より、ボルトを取付対称の薄板状をした部分に螺着する場合、予めこの取付対象の板状部分に取付孔を穿設してこの取付孔に裏ナットを固定しておき、ボルトをこの取付孔の裏ナットに螺着して取付対象と他の部材とを接合する方法が採られている。取付対称としては種々のものがあり、梁や根太等の略角筒状をしたものの場合、これらの板状部分に取付孔を穿設してこの取付孔に裏ナットを溶接により固定することが良く行われている(例えば特許文献1,特許文献2参照)。
【0003】
しかしながら、このようにナットを溶接にて取付対称に固定しておく場合、その溶接作業が必要なため工程が増大するものであった。また更に、長い角筒状をした根太のような取付対称の内面にナットを溶接により固定する場合、その取付部が根太の中央部である場合には根太内の奥方に溶接用具を手で挿入しなければならないため、実質的に取付けが不可能なものであった。

【発明が解決しようとする課題】
本発明は上記の点に鑑みて発明したものであって、その目的とするところは、溶接によらずにナットを取付対称に設けた取付孔の周縁に取付けることができるナットのかしめ方法を提供するにある。
【0006】
【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にあっては、取付対象の板状部分11に穿孔した取付孔12の周縁12aにかしめて取付けるナット2のかしめ方法であって、ナット2の一端面に該ナット2の螺合孔20の径より若干大径の円筒状をした被かしめ部21を突設し、かしめ用治具3を、先端部に上記ナット2と螺合する螺合部31を形成すると共に、前記螺合部31を突出する基部に先端側の径が上記ナット2の被かしめ部21の径より小径で後端側の径が被かしめ部21の径より大径となったかしめ部32を形成し且つ後端部に回転部33を設けて構成し、上記ナット2の被かしめ部21を取付対象1の取付孔12の一側より挿入して他側に突出させると共に、該ナット2の回転を防止するための保持部材を取付孔12の一側に位置するナット2の外周の多角形部22に被嵌してナット2を保持し、次に、かしめ用治具3の螺合部31を取付孔12の他側より突出する上記ナット2の被かしめ部21内に挿入して該ナット2の螺合孔20に螺合し、かしめ用治具3の回転部33を回転してかしめ部32の先端側より上記ナット2の被かしめ部21内に螺進させてかしめ部32の後端側の被かしめ部21の径より大径となった部分で前記被かしめ部21をかしめて取付孔12の周縁12aに取付けることを特徴とするものである。このような構成とすることで、溶接することなくナット2を取付対称1の取付孔12に固定することが可能となる。
【0007】
また、ナット2の被かしめ部21の先端の周端縁から基部に向かって切込まれる複数の切欠部23を形成し、かしめ用治具3のかしめ部32にてかしめる際に被かしめ部21の先端の周端縁を取付対称1の取付孔12の周縁12aに食い込ませることが好ましい。このような構成とすることで、被かしめ部21の先端を取付孔12の周縁12aへ食い込ませてナット2の取付孔12への固定が更に強固なものとなる。
【0008】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【0009】
本実施形態では、ナット2を取付ける取付対称1として、図10に示すような大引5を用いている。
【0010】
大引5は、長い角筒状をしたもので、その側壁にボルトを螺着するための取付孔12を貫通形成してある。そして、この大引5の取付孔12の周縁内面にナット2を取付けるものである。なお、図10中の6は支持プレートを、7は支持プレート6を上下調整自在とするアジャスタ部を、8は束を、9は床スラブを示す。
【0011】
ナット2は、図2に示すように、通常の六角ナット2、即ち、ナット2の螺合孔20の開口方向廻りの周面に六角形状をした多角形部22を有するナット2を用いる。そして、このナット2の一端面、即ち、開口方向に面する一面に被かしめ部21を突設するものである。被かしめ部21は、ナット2の螺合孔20の径よりも若干大径の円筒状となるようにナット2と一体的に形成してあり、取付対称1の取付孔12に一側(図1,図3乃至図7,図9における下側)より挿入した際、その先端部が他側(図1,図3乃至図7,図9における上側)に突出した状態となるものである(図4参照)。このようなナット2は、後述するが、かしめ用治具3にて被かしめ部21をかしめて取付対称1の取付孔12の周縁12aに取付けられる(図1参照)。
【0012】
かしめ用治具3は、図1等に示すように、概略ボルト状をしたもので、先端に上記ナット2の螺合孔20に螺合する螺合部31を形成し、この螺合部31を突出する基部にかしめ部32を形成し、かしめ部32の後端部側に回転部33を設けるものである。
【0013】
かしめ部32は、先端側(即ち螺合部31を突出する側であって図1における下側)端部の径が上記ナット2の被かしめ部21の径とほぼ同じか又はこれより小径となるとともに、後端側(即ち螺合部31を突出した側と反対側で回転部33側で、図1における上側)端部の径が上記ナット2の被かしめ部21の径より大径となるものである。このかしめ部32の途中には、先端側を向く面を形成してあり、ナット2の被かしめ部21を反らせて折り曲げるのを可能とし、ナット2の被かしめ部21の外端縁を取付孔12の周縁12aに強固に取付ることが可能となる。
【0014】
このようなナット2の取付対称1の取付孔12への取付けについて説明する。
【0015】
まず、図3に示すように、ナット2を取付対称1の取付孔12の一側に配置し、図4に示すように、ナット2の被かしめ部21を取付対称1の他側に突出させる。次に、保持部材をナット2の多角形部22に被嵌してナット2を保持し、図5に示すように、かしめ用治具3の螺合部31を取付孔12の他側より突出するナット2の被かしめ部21内に挿入していく。次に、図6に示すように、かしめ用治具3の螺合部31をナット2の螺合孔20に螺合させてかしめ用治具3の回転部33を回転して螺進させていき、図7に示すように、かしめ用治具3のかしめ部32の後端側の被かしめ部21の径より大径となった部分で前記被かしめ部21をかしめて取付孔12の周縁12aにナット2を取付けるものである。
【0016】
以上のようにすることで、ナット2を溶接によらずに取付対象1の取付孔12に取付けることが可能となり、取付対象1が大引5のような長い角筒状をしたものであっても、その中央部に取付ける際に溶接用具を取付対称1の内部奥方に入れる必要がなく、ナット2の取付け作業が容易となる。
【0017】
またこの時、図8に示すように、ナット2の被かしめ部21の先端の周端縁から基部に向かって切込まれる複数の切欠部23を形成しておき、かしめ用治具3のかしめ部32にてかしめる際、被かしめ部21の先端の周端縁を取付対称1の取付孔12の周縁12aに食い込ませてもよいものである。このようにすることで、ナット2の被かしめ部21とナット2の本体とで取付対称1の板状部分11をかしめて挟着するのに加えて、被かしめ部21の食い込んだ先端で取付孔12の周縁12aへのナット2の固定が更に強固なものとなる。
【0018】
【発明の効果】
上述のように請求項1記載の発明にあっては、取付対象の板状部分に穿孔した取付孔の周縁にかしめて取付けるナットのかしめ方法であって、ナットの一端面に該ナットの螺合孔の径より若干大径の円筒状をした被かしめ部を突設し、かしめ用治具を、先端部に上記ナットと螺合する螺合部を形成すると共に、前記螺合部を突出する基部に先端側の径が上記ナットの被かしめ部の径より小径で後端側の径が被かしめ部の径より大径となったかしめ部を形成し且つ、後端部に回転部を設けて構成し、上記ナットの被かしめ部を取付対象の取付孔の一側より挿入して他側に突出させると共に、該ナットの回転を防止するための保持部材を取付孔の一側に位置するナットの外周の多角形部に被嵌してナットを保持し、次に、かしめ用治具の螺合部を取付孔の他側より突出する上記ナットの被かしめ部内に挿入して該ナットの螺合孔に螺合し、かしめ用治具の回転部を回転してかしめ部の先端側より上記ナットの被かしめ部内に螺進させてかしめ部の後端側の被かしめ部の径より大径となった部分で前記被かしめ部をかしめて取付孔の周縁に取付けるので、溶接することなくナットを取付対称の取付孔に固定することが可能となる。
【0019】
また、請求項2記載の発明にあっては、請求項1記載の発明の効果に加えて、ナットの被かしめ部の先端の周端縁から基部に向かって切込まれる複数の切欠部を形成し、かしめ用治具のかしめ部にてかしめる際に被かしめ部の先端の周端縁を取付対称の取付孔の周縁表面に食い込ませるので、被かしめ部の先端を取付孔の周縁へ食い込ませてナットの取付孔への固定が更に強固なものとなる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of caulking a nut for caulking a nut in a mounting hole formed in a plate-shaped portion having mounting symmetry.
[0002]
[Prior art]
Conventionally, when a bolt is screwed onto a thin plate-shaped portion to be mounted, a mounting hole is drilled in advance in the plate portion to be mounted, and a back nut is fixed in the mounting hole, and the bolt is removed. A method has been adopted in which a mounting object and another member are joined by screwing to a back nut of the mounting hole. There are various types of mounting symmetry, and in the case of a substantially rectangular cylindrical shape such as a beam or a joist, it is possible to drill a mounting hole in these plate-shaped parts and fix the back nut to this mounting hole by welding. It is often performed (for example, see Patent Documents 1 and 2).
[0003]
However, in the case where the nut is fixed symmetrically by welding in this manner, the number of steps is increased because the welding operation is required. Furthermore, when the nut is fixed by welding to the inner surface of a long tubing-shaped joist that is symmetrical to the installation, if the mounting part is the center of the joist, the welding tool is inserted by hand into the back of the joist. Therefore, installation was practically impossible.

The crimping portion 21 is provided so as to protrude from one end surface of the nut 2, that is, one surface facing the opening direction. The swaged portion 21 is formed integrally with the nut 2 so as to form a cylindrical shape having a diameter slightly larger than the diameter of the screw hole 20 of the nut 2, and one side (see FIG. 1, when inserted from the lower side in FIGS. 3 to 7 and 9, the leading end thereof projects to the other side (the upper side in FIGS. 1, 3 to 7 and 9) ( (See FIG. 4). As will be described later, such a nut 2 is attached to the peripheral edge 12a of the attachment hole 12 of the attachment symmetry 1 by caulking the caulked portion 21 by the caulking jig 3 (see FIG. 1).
[0012]
As shown in FIG. 1 and the like, the caulking jig 3 is substantially in the shape of a bolt, and has a threaded portion 31 that is screwed into the threaded hole 20 of the nut 2 at its tip. A caulking portion 32 is formed on a base portion projecting from the shaft, and a rotating portion 33 is provided on a rear end side of the caulking portion 32.
[0013]
The caulked portion 32 has a tip end (that is, a side protruding the screwed portion 31 and a lower side in FIG. 1) whose end portion diameter is substantially equal to or smaller than the diameter of the swaged portion 21 of the nut 2. In addition, the diameter of the rear end side (that is, the side opposite to the side where the screwing portion 31 protrudes and the rotating portion 33 side, the upper side in FIG. 1) is larger than the diameter of the swaged portion 21 of the nut 2.

【The invention's effect】
As described above, according to the first aspect of the present invention, there is provided a method of caulking a nut which is caulked to a peripheral edge of a mounting hole formed in a plate portion to be mounted, wherein the nut is screwed to one end surface of the nut. A cylindrical caulked portion having a diameter slightly larger than the diameter of the hole is protruded, and a jig for caulking is formed at a tip portion with a screwing portion to be screwed with the nut, and the screwing portion is protruded. The base has a caulked portion in which the diameter on the tip side is smaller than the diameter of the caulked portion of the nut and the diameter on the rear end is larger than the diameter of the caulked portion, and a rotating portion is provided at the rear end. The caulked portion of the nut is inserted from one side of the mounting hole to be mounted and protruded to the other side, and a holding member for preventing rotation of the nut is positioned on one side of the mounting hole. Fit the polygon on the outer periphery of the nut to hold the nut, and then tighten the screwing part of the caulking jig. The nut is inserted into the caulked portion of the nut protruding from the other side of the hole, screwed into the screwing hole of the nut, and the rotating portion of the caulking jig is rotated to cover the nut from the tip end side of the caulked portion. Since the swaged portion is screwed into the swaged portion and caulked at the portion where the diameter of the swaged portion on the rear end side of the swaged portion is larger than the diameter of the swaged portion and attached to the periphery of the mounting hole, the nut is symmetrically mounted without welding.
