Description

本発明は、止具を止具連結対象部の挿通孔に係止させる止具連結方法、この止具連結方法を用いたパイプ支持具の製造方法、止具係止構造およびこの止具連結構造を有したパイプ支持具に関する。   The present invention relates to a stopper connection method for locking a stopper to an insertion hole of a fastener connection target portion, a method for manufacturing a pipe support using the fastener connection method, a stopper locking structure, and the stopper connection structure. The present invention relates to a pipe support having

従来のパイプ支持具は、１組のパイプ支持材をヒンジ結合により回動可能に組み合わせて構成され、それぞれのパイプ支持材の固定部が、外壁に取り付けたパイプ支持具用の取付具に取り付け固定されるようになっている（たとえば、特許文献１参照）。   A conventional pipe support is configured by combining a pair of pipe support materials so as to be rotatable by hinge coupling, and the fixing portions of the pipe support materials are fixedly attached to the pipe support fixtures attached to the outer wall. (For example, refer to Patent Document 1).

具体的には、図４に示すように、パイプ支持具１００を構成するヒンジ結合された２つのパイプ支持材１１０はそれぞれ、バンド部１１１と、挿通孔１１３を有した平板状の固定部１１２とを有しており、これらの固定部１１２、１１２で挿通孔３ａ付きの取付具３を挟持した状態で、挿通孔１１３、３ａ、１１３にボルト１２０を通してナット１２１止めする固定構造となっている。   Specifically, as shown in FIG. 4, the two hinged pipe support members 110 constituting the pipe support 100 are respectively composed of a band portion 111 and a flat plate-like fixing portion 112 having an insertion hole 113. In the state where the fixture 3 with the insertion hole 3a is sandwiched between the fixing portions 112 and 112, the nuts 121 are fixed to the insertion holes 113, 3a and 113 through bolts 120.

ところで、このような止具（ボルト１２０）を用いた固定作業は、作業効率を考慮して、あらかじめ一方の固定部１１２（止具連結対象部）にボルト１２０を脱落防止プレート（不図示）などで仮止めしておき、その後、現場で本固定の作業をすることが一般的である。この脱落防止プレートはプラスチック製の薄いものであるため、ボルト１２０の軸部に取り付けたまま施工してもよく、よって取り外しの手間も不要となる。このような脱落防止プレートは、その他の種々の施工現場においてもボルトの脱落防止目的として多く利用されている。   By the way, in the fixing work using such a fastener (bolt 120), in consideration of work efficiency, the bolt 120 is attached to one fixing portion 112 (fastener connection target portion) in advance and a fall-off prevention plate (not shown) or the like. It is common to temporarily fix it at, and then perform the actual fixing work at the site. Since the drop-off prevention plate is a thin plastic plate, it may be installed while being attached to the shaft portion of the bolt 120, and thus the labor of removal is not required. Such a drop-off prevention plate is often used in various other construction sites for the purpose of preventing bolt drop-off.

また、特許文献２に記載された方法を用いてボルトの脱落防止を図ることも想定できる。この方法は、挿通孔に挿通された止具（ピン）の軸部の周囲に配した固定部材を塑性変形させることで、止具を止具連結対象部（同文献の例では基材）に固着させるようになっている。   It can also be assumed that the bolt is prevented from falling off using the method described in Patent Document 2. In this method, the fixing member disposed around the shaft portion of the stopper (pin) inserted through the insertion hole is plastically deformed, so that the stopper is connected to the stopper connection target portion (base material in the example of the same document). It is designed to be fixed.

しかしながら、脱落防止プレートや特許文献２の固定部材を用いる方法では構成部材が従来に比べ増えるため、部材管理をするうえでデメリットとなる。また、特許文献２に記載の方法では、固定部材を塑性変形させるプレス加工の処理を必要とされるから、コスト高にもなる。   However, in the method using the drop prevention plate or the fixing member of Patent Document 2, the number of constituent members is increased as compared with the conventional method, which is a demerit in managing the members. In addition, the method described in Patent Document 2 requires a pressing process that plastically deforms the fixing member, which increases the cost.

また、作業中のボルトの脱落を防止する他の対策として、圧入によりボルトを挿通孔に係止できるように軸部の根元に圧入部を設けたかしめボルトを用いる方法も想定できるが、この方法によれば、この種のかしめボルトが高価であるためコスト高になることは避けられない。   In addition, as another measure for preventing the bolt from falling off during work, a method using a crimped bolt provided with a press-fit portion at the base of the shaft portion so that the bolt can be locked in the insertion hole by press-fitting can be assumed. Therefore, since this type of caulking bolt is expensive, it is inevitable that the cost will increase.

本発明は、このような事情を考慮して提案されたもので、その目的は、使用する部材が従来に比べ増えることがなく、かつ製造、施工するうえでコスト高となることもなく、止具を脱落しないように止具連結対象部に連結できる止具連結方法、パイプ支持具の製造方法、止具連結構造およびパイプ支持具を提供することにある。   The present invention has been proposed in view of such circumstances, and its purpose is to prevent the increase in the number of members to be used compared to the prior art, without increasing the cost for manufacturing and construction.

以下に、本発明の実施の形態について、添付図面を参照しながら説明する。まず、本止具連結方法の概略について説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings. First, an outline of this fastener connecting method will be described.

本止具連結方法は、止具連結対象部（本実施形態の例では固定部２０）に形成された挿通孔２１に止具（本実施形態の例ではボルト３０）を挿通し、挿通孔２１の周縁部２２をプレス金型４０にてプレス加工して挿通孔２１の内寸法を小さくすることで止具を止具連結対象部に係着連結させる手順である（図２および図３参照）。   The present fastener connecting method inserts a fastener (bolt 30 in the example of the present embodiment) through the insertion hole 21 formed in the fastener connection target portion (fixed portion 20 in the example of the present embodiment), and the insertion hole 21. This is a procedure in which the peripheral edge portion 22 is pressed with a press die 40 to reduce the inner dimension of the insertion hole 21 so that the fastener is fixedly connected to the fastener connection target portion (see FIGS. 2 and 3). .

このような止具連結方法は、たとえばパイプ支持具５の製造方法において用いられる。以下、パイプ支持具５およびその製造方法を例に挙げ、止具連結方法および止具連結構造について、図１〜図４をもとに説明する。   Such a fastener connecting method is used in a method for manufacturing the pipe support 5, for example. Hereinafter, the pipe support 5 and the manufacturing method thereof will be described as examples, and the stopper connection method and the stopper connection structure will be described with reference to FIGS.

パイプ支持具５は、図１（ａ）に示すように、１組のパイプ支持材１０、１０を組み合わせてなる。パイプ支持材１０は、鉄、鋼、ステンレスなどの金属材料などよりなり、パイプ１を抱持するバンド部１１と、挿通孔２１、２１を有した固定部２０とを備えており、固定部２０、２０どうしで取付対象を挟持した状態で、ボルト３０よりなる止具を挿通孔２１に挿通して取付対象に固定されるようになっている。この固定部２０の内面（取付対象を挟持する面）は、挿通孔２１を除く面が平坦面とされる。パイプ支持具５においては、これらの固定部２０、２０のうちの一方の固定部２０が、ボルト３０、３０が連結される上記の止具連結対象部とされる。   The pipe support 5 is formed by combining a pair of pipe support members 10 and 10 as shown in FIG. The pipe support member 10 is made of a metal material such as iron, steel, and stainless steel, and includes a band portion 11 that holds the pipe 1 and a fixing portion 20 having insertion holes 21 and 21. In a state where the object to be attached is sandwiched between 20, a stopper made of a bolt 30 is inserted into the insertion hole 21 and fixed to the object to be attached. The inner surface of the fixing portion 20 (the surface that holds the attachment target) is a flat surface excluding the insertion hole 21. In the pipe support 5, one of the fixing parts 20, 20 is the above-described stopper connection target part to which the bolts 30, 30 are connected.

ここで、取付対象とは、パイプ１を配設するためのパイプ支持具５を外壁に沿って取り付けるための、外壁に固定された取付具３である。取付具３は平板状とされ、そこには両横方向に貫通する、前後に長い長孔３ａが開設されている。この取付具３を２つの固定部２０、２０で挟み、長孔３ａでパイプ支持具５の出具合を調整して、一方の固定部２０の２箇所の挿通孔２１、２１に連結した止具を構成するボルト３０と、他方の固定部２０の挿通孔２１から出たボルト３０の軸部３２に螺合するナット３６とでパイプ支持具５を固定する取付構造となっている。   Here, the attachment target is the fixture 3 fixed to the outer wall for attaching the pipe support 5 for arranging the pipe 1 along the outer wall. The fixture 3 has a flat plate shape, and a long hole 3a extending in the front-rear direction is formed therethrough. The fixture 3 is sandwiched between the two fixing portions 20 and 20, adjusted by the long hole 3 a to adjust the degree of the pipe support 5, and connected to the two insertion holes 21 and 21 of the one fixing portion 20. The pipe support 5 is fixed by the bolt 30 that constitutes the nut 30 and the nut 36 that is screwed into the shaft portion 32 of the bolt 30 that is protruded from the insertion hole 21 of the other fixing portion 20.

本実施形態では、施工時においては、図１（ａ）に示すように、すでに一方の固定部２０にボルト３０が係着連結されている。ボルト３０が連結した固定部２０の軸部突出側（内面側）は、図１（ｂ）の部分斜視図のようになっている。すなわち、図１（ｂ）に示すように、たとえば直径が約５ｍｍのボルト３０を用いた場合、ボルト３０を連結した固定部２０の軸部側では、挿通孔２１の周縁部２２に、幅０．１〜０．５ｍｍ程度の環状溝状部（凹み）が形成されている。固定部２０の内面は、ボルト３０の連結前の状態では挿通孔２１を除き凹凸なく平坦な面となっているが、ボルト３０を連結させた後では、周縁部２２が段差を介した溝状環状部に変形している。   In this embodiment, at the time of construction, as shown in FIG. 1A, the bolt 30 is already engaged and connected to the one fixing portion 20. The shaft portion protruding side (inner surface side) of the fixed portion 20 to which the bolt 30 is connected is as shown in the partial perspective view of FIG. That is, as shown in FIG. 1B, for example, when a bolt 30 having a diameter of about 5 mm is used, a width 0 is provided at the peripheral portion 22 of the insertion hole 21 on the shaft portion side of the fixing portion 20 to which the bolt 30 is connected. An annular groove (dent) of about 1 to 0.5 mm is formed. The inner surface of the fixing portion 20 is a flat surface without unevenness except for the insertion hole 21 in a state before the bolt 30 is connected, but after the bolt 30 is connected, the peripheral portion 22 is a groove-like shape through a step. It is deformed into an annular part.

その周縁部２２は、図１（ｂ）に示すように、周縁部２２とその外側を区別するように円形が表れている。この円形は、段差の角部２３（図１（ｂ）の拡大縦断面図）が表面に表れたものである。また、周縁部２２の内部（角部２３とボルト３０の軸部３２との間）は他の面よりも凹んでおり、その凹み空間の中で軸部側に突出した膨出部２４が形成されている。膨出部２４の表面側は、図１（ｂ）の例では丸くなっているが、これには限らず、図１（ｃ）のように凹湾曲したものでもよく、図１（ｄ）のように凹凸形状のものでもよい。この表面側の形状は、図２の説明において後述するプレス金型４０の形状や押圧の程度によっておおむね定まる。   As shown in FIG. 1B, the peripheral edge 22 has a circular shape so as to distinguish the peripheral edge 22 from the outside. This circular shape has a stepped corner 23 (enlarged longitudinal sectional view of FIG. 1B) appearing on the surface. Further, the inside of the peripheral edge portion 22 (between the corner portion 23 and the shaft portion 32 of the bolt 30) is recessed from the other surface, and a bulging portion 24 protruding toward the shaft portion side is formed in the recessed space. Has been. The surface side of the bulging portion 24 is rounded in the example of FIG. 1B, but is not limited thereto, and may be concavely curved as shown in FIG. 1C, as shown in FIG. As shown in FIG. The shape on the surface side is generally determined by the shape of the press die 40 and the degree of pressing described later in the description of FIG.

これらの図例では、膨出部２４が軸部３２のねじ山３３、３３間（ねじ溝３４）にしっかりと嵌り込んでおり、それにより、ボルト３０は固定部２０に固着された状態（ボルト３０が固定部２０に対して動かない状態）となっている。しかしながら、このような係着には限定されず、図２および図３（特に図３（ｂ）参照）に示すように、膨出部２４がボルト３０の軸部３２のねじ溝３４に遊嵌状態となってボルト３０が係着されるものであってもよい。すくなくとも、ボルト３０が軸部方向へ移動しない程度の係着構造とされることが望ましい。なお、遊嵌状態の場合には、ボルト３０の軸部３２が軸回りに回転できることが、パイプ支持具５を取付具３に取り付けるためのボルト止め作業をするうえで望ましい。   In these examples, the bulging portion 24 is firmly fitted between the screw threads 33 and 33 (screw groove 34) of the shaft portion 32, whereby the bolt 30 is fixed to the fixing portion 20 (bolt 30 is in a state in which it does not move with respect to the fixed portion 20). However, the engagement is not limited to such engagement, and the bulging portion 24 is loosely fitted in the thread groove 34 of the shaft portion 32 of the bolt 30 as shown in FIGS. The bolt 30 may be engaged in a state. At least, it is desirable that the engagement structure is such that the bolt 30 does not move in the axial direction. In the loose fitting state, it is desirable that the shaft portion 32 of the bolt 30 can rotate around the axis in order to perform the bolting operation for attaching the pipe support 5 to the attachment 3.

このパイプ支持具５に採用される止具連結構造は、ボルト３０よりなる止具が挿通孔２１に挿通された状態で挿通孔２１の周縁部２２がプレス加工されることで挿通孔２１の内寸法が小さくなった止具連結対象部（固定部２０）に係着連結されてなるものでる。このプレス加工は金型を用いてなされる。   The stopper connecting structure employed in the pipe support 5 is such that the peripheral portion 22 of the insertion hole 21 is pressed in a state in which the stopper made of the bolt 30 is inserted into the insertion hole 21, so that the inner portion of the insertion hole 21 is pressed. It is engaged and connected to a stopper connection target portion (fixed portion 20) whose size is reduced. This pressing is performed using a mold.

ついで、金型を用いた具体的な止具連結方法（を用いたパイプ支持具の製造方法）について、図２および図３をもとに説明する。   Next, a specific stopper connecting method using a mold (a method for manufacturing a pipe support using the die) will be described with reference to FIGS.

まず、ボルト３０が係着連結される一方のパイプ支持材１０を用意する。このパイプ支持材１０は、パイプ支持材１０どうしをヒンジ結合する前のものであり、バンド部１１が形成される前のバンド部１１部分が湾曲していない平板帯板状のものであってもよいし、バンド部１１が形成された後のバンド部１１部分が湾曲したものであってもよい。金型としては、プレス金型４０と載置台５０とを用いる。   First, one pipe support material 10 to which the bolt 30 is engaged and connected is prepared. This pipe support material 10 is a thing before the pipe support materials 10 are hinge-coupled, and even if the band part 11 part before the band part 11 is formed is a flat belt-like plate shape which is not curved. Alternatively, the band portion 11 after the band portion 11 is formed may be curved. As the mold, a press mold 40 and a mounting table 50 are used.

載置台５０は、図２（ａ）に示すように、ボルト３０の頭部３１が収容される、上方に向け開口した凹部５１、５１が、固定部２０の２つの挿通孔２１、２１の位置関係に対応して設けられた台である。この凹部５１はボルト３０の頭部３１がずれない程度に、頭部３１の大きさにおおむね合致したものとされることが望ましい。その載置台５０に、凹部５１、５１に頭部３１、３１が収容されるように軸部３２、３２を上に向けたボルト３０、３０をセットする。そして、軸部３２、３２の上方から、固定部２０の挿通孔２１、２１に軸部３２、３２が通るようにパイプ支持材１０をセットする（以上、図２（ａ）参照）。   As shown in FIG. 2 (a), the mounting table 50 has recesses 51, 51 opened upward, in which the heads 31 of the bolts 30 are accommodated, and the positions of the two insertion holes 21, 21 of the fixing unit 20. It is a stand provided corresponding to the relationship. It is desirable that the concave portion 51 is substantially matched with the size of the head portion 31 so that the head portion 31 of the bolt 30 is not displaced. On the mounting table 50, bolts 30, 30 with the shaft portions 32, 32 facing upward are set so that the head portions 31, 31 are accommodated in the recesses 51, 51. Then, the pipe support member 10 is set from above the shaft portions 32 and 32 so that the shaft portions 32 and 32 pass through the insertion holes 21 and 21 of the fixed portion 20 (see FIG. 2A).

プレス金型４０は、図２（ｂ）に示すように、下方に突出した２つの突状成形部４１、４１が、載置台５０の２つの凹部５１、５１に対応して設けられた金型である。この突状成形部４１、４１は底面視でリング状とされ、その開口は上方に向けて円柱状に貫通している。また、突状成形部４１の側面視形状は円錐台とされる。ようするに、この突状成形部４１は、挿通孔２１の形状に合致するように円形のリング状に突出し、側面視で山形状をなしている。なお、本プレス金型４０はその先端で挿通孔２１の周縁部２２をプレス加工するものであるためリング状をなしているが、全体形状は円錐台形状でなくてもよい。   As shown in FIG. 2 (b), the press mold 40 has a mold in which two projecting portions 41 and 41 projecting downward are provided corresponding to the two recesses 51 and 51 of the mounting table 50. It is. The projecting portions 41 and 41 are ring-shaped when viewed from the bottom, and the opening penetrates upward in a columnar shape. Further, the side-view shape of the protrusion-shaped part 41 is a truncated cone. Thus, the projecting shaped portion 41 protrudes in a circular ring shape so as to match the shape of the insertion hole 21 and has a mountain shape in a side view. In addition, since this press metal mold | die 40 presses the peripheral part 22 of the penetration hole 21 in the front-end | tip, it has comprised the ring shape, However, The whole shape does not need to be a truncated cone shape.

突状成形部４１の先端のリング部４２の厚さの寸法は、周縁部２２の幅寸法におおむね対応した寸法とされる。この突状成形部４１の先端が挿通孔２１の周縁部２２に対して押圧する部位である。このプレス金型４０を、リング部４２（貫通孔４３）と軸部３２の位置とを位置合わせして上方よりプレスする（図２（ｂ）参照）。   The dimension of the thickness of the ring part 42 at the tip of the protrusion-shaped part 41 is a dimension that roughly corresponds to the width dimension of the peripheral edge part 22. The tip of the protruding molded part 41 is a part that presses against the peripheral part 22 of the insertion hole 21. The press die 40 is pressed from above by aligning the ring portion 42 (through hole 43) and the position of the shaft portion 32 (see FIG. 2B).

図３（ａ）は、プレス金型４０の先端のリング部４２が周縁部２２に当接したときの状態図である。押圧の程度としては、本例の場合、周縁部２２が約０．１ｍｍ凹む程度であり、そのように押圧した結果、周縁部２２は図３（ｂ）の拡大図のように変形する。   FIG. 3A is a state diagram when the ring portion 42 at the tip of the press die 40 contacts the peripheral edge portion 22. In this example, the degree of pressing is such that the peripheral edge 22 is recessed by about 0.1 mm. As a result of such pressing, the peripheral edge 22 is deformed as shown in the enlarged view of FIG.

このようなプレス加工の結果、周縁部２２には凹みによる溝状環状部が形成され、その溝状環状部内では、固定部２０の材料が挿通孔２１の円中心に向かうように塑性変形して膨出部２４が形成される。つまり、このプレスの結果、挿通孔２１の内寸法（内径寸法）は縮小する。   As a result of such pressing, a groove-like annular portion is formed in the peripheral edge portion 22, and in the groove-like annular portion, the material of the fixing portion 20 is plastically deformed toward the circle center of the insertion hole 21. A bulging portion 24 is formed. That is, as a result of this pressing, the inner dimension (inner diameter dimension) of the insertion hole 21 is reduced.

図３（ｃ）は、挿通孔２１とその周縁部２２の平面図であり、図中、Ｓ１はプレス加工前の周縁部２２の幅寸法であり、Ｓ２はプレス加工により膨出部２４が内側に突出した後の周縁部２２の幅寸法である。このようにプレスによって、挿通孔２１の（表面側の）内径寸法は縮小する。   FIG. 3C is a plan view of the insertion hole 21 and its peripheral edge portion 22, in which S <b> 1 is the width dimension of the peripheral edge portion 22 before press working, and S <b> 2 is the inside of the bulging portion 24 by press working. It is the width dimension of the peripheral part 22 after protruding in the direction. Thus, the inner diameter dimension (on the front surface side) of the insertion hole 21 is reduced by the press.

そして、膨出部２４の軸部３２側の端部はボルト３０のねじ山３３に引っ掛かり、ねじ溝３４に遊嵌した状態となる。すなわち、この状態ではボルト３０は挿通孔２１に対し、軸方向には移動不可であるが、回転可能な状態となっている。   The end portion of the bulging portion 24 on the shaft portion 32 side is caught by the thread 33 of the bolt 30 and is loosely fitted in the screw groove 34. That is, in this state, the bolt 30 is not movable in the axial direction with respect to the insertion hole 21 but is rotatable.

このように、金型（プレス金型４０）を用いた止具連結方法を用いることにより、ボルト３０は固定部２０の挿通孔２１に脱落不可の状態に係着連結されることとなる。したがって、パイプ支持具５を施工する際にはボルト３０が脱落するおそれがなく、作業がしやすくなる。また、脱落防止プレートなど他の部材を必要としない。このように従来に比べ部材が増えないため、製品コストが高くなることはない。   In this way, by using a fastener connecting method using a mold (press mold 40), the bolt 30 is fixedly connected to the insertion hole 21 of the fixing portion 20 in a state where it cannot be dropped off. Therefore, when constructing the pipe support 5, there is no fear that the bolt 30 will drop off, and the operation will be easy. Further, no other member such as a drop-off prevention plate is required. Thus, since the number of members does not increase as compared with the conventional case, the product cost does not increase.

また、図３（ｂ）に示すように、ボルト３０が回転する程度の係着であれば、他の固定部２０（図１（ａ）参照）側でナット３６を螺合する際に、ボルト３０を回転操作することができ、従来どおりの施工作業を行うことができる。もちろん、ボルト３０は固定部２０に固着されてもよく、その場合でもナット３６を回転操作すればよいので、ほとんど問題はない。   Further, as shown in FIG. 3B, when the bolt 30 is engaged so as to rotate, the bolt 36 is screwed when the nut 36 is screwed on the other fixing portion 20 (see FIG. 1A) side. 30 can be rotated and construction work can be performed as usual. Of course, the bolt 30 may be fixed to the fixing portion 20, and even in that case, the nut 36 only needs to be rotated, so there is almost no problem.

さらに本実施形態では、挿通孔２１（周縁部２２）の形状に合致した平面視円形リング状の突状成形部４１を有したプレス金型４０を用いているため、リング部４２により周縁部２２を均一に押圧でき、ボルト３０の軸部３２を歪んだ状態に取り付けることを回避することができ、スムーズな施工作業を実施することができる。なお、プレス金型４０としては、周縁部２２の一部（たとえば４箇所）を押圧するような形状であってもよい。   Furthermore, in this embodiment, since the press die 40 having the projecting shaped part 41 having a circular ring shape in plan view that matches the shape of the insertion hole 21 (peripheral part 22) is used, the peripheral part 22 is formed by the ring part 42. Can be pressed uniformly, and it can avoid attaching the axial part 32 of the volt | bolt 30 in the distorted state, and can implement a smooth construction operation. The press die 40 may have a shape that presses a part (for example, four places) of the peripheral edge portion 22.

また、挿通孔２１が長孔である場合、その周縁部のうち長孔の短手方向の部位を押圧することで、長孔においてもボルト３０を係着することができる。もちろん、長孔の全周周縁部を押圧するようにしてもよい。   Moreover, when the insertion hole 21 is a long hole, the volt | bolt 30 can be engaged also in a long hole by pressing the site | part of the transversal direction of a long hole among the peripheral parts. Of course, you may make it press the perimeter edge part of a long hole.

また、１列に複数のボルト３０の頭部３１を収容できるように、凹部５１、５１の代わりに２列の凹溝を載置台に設けるようにしてもよい。このような載置台を用いれば複数のパイプ支持材１０を並べて配置でき、複数のプレス金型４０を用いて、あるいは１つのプレス金型４０を用いて順々にプレス加工することができる。   Further, two rows of concave grooves may be provided on the mounting table instead of the concave portions 51, 51 so that the heads 31 of the plurality of bolts 30 can be accommodated in one row. By using such a mounting table, a plurality of pipe support members 10 can be arranged side by side, and can be pressed in sequence using a plurality of press dies 40 or a single press dies 40.

さらに、本実施形態のプレス加工では載置台５０が用いてあるが、これの代わりにボルト３０の頭部３１を固定する他の固定手段を用いてもよい。また、プレス金型４０を下方より上方に移動させてプレス加工するようにしてもよい。   Furthermore, although the mounting table 50 is used in the press working of the present embodiment, other fixing means for fixing the head portion 31 of the bolt 30 may be used instead. Alternatively, the press mold 40 may be moved from below to above for press working.

また、パイプ支持材１０のバンド部１１の成形は、ボルト３０の連結のための上記止具連結工程の前または後になされればよいが、止具連結工程と同時になされるようにしてもよい。たとえば、止具連結構造を成形でき、かつバンド部１１も成形できるプレス金型を用いてもよい。   In addition, the band portion 11 of the pipe support member 10 may be formed before or after the fastener connecting step for connecting the bolts 30, but may be performed simultaneously with the stopper connecting step. For example, you may use the press metal mold | die which can shape | mold a fastener connection structure and can also shape | mold the band part 11. FIG.

以上では、ボルト３０よりなる止具を固定部２０（止具連結対象部）に連結する方法を例示し説明したが、リベットよりなる止具を止具連結対象部に連結することも可能である。リベットを挿通孔２１の周縁部２２に係着させるためには、リベットの外周面に、周縁部２２に塑性変形させた膨出部２４を当接させることが望ましい。つまり、リベットの抜けを回避するためには、リベットが止具連結対象部に固着連結されることが望ましい。なお、リベットの外周面に膨出部２４が引っ掛かる凹凸を設ければ、ボルト３０の場合と同様に、リベットを回転可能な状態に止具連結対象部に連結することも可能である。   In the above, the method of connecting the fastener made of the bolt 30 to the fixing portion 20 (stopper connection target portion) has been illustrated and described. However, it is also possible to connect the stopper made of rivets to the stop connection target portion. . In order to engage the rivet with the peripheral portion 22 of the insertion hole 21, it is desirable to bring the bulging portion 24 plastically deformed into the peripheral portion 22 into contact with the outer peripheral surface of the rivet. That is, in order to avoid the rivet from coming off, it is desirable that the rivet is fixedly connected to the stopper connection target portion. In addition, if the unevenness | corrugation which the bulging part 24 catches in the outer peripheral surface of a rivet is provided, it is also possible to connect a rivet to a fastener connection object part in the state which can be rotated similarly to the case of the volt | bolt 30.

本発明は、ボルトよりなる止具を止具連結対象部の挿通孔に係止させる止具連結方法、この止具連結方法を用いたパイプ支持具の製造方法、止具連結構造およびこの止具連結構造を有したパイプ支持具に関する。 The present invention relates to a fastener connecting method for locking a fastener made of a bolt to an insertion hole of a fastener connection target portion, a method for manufacturing a pipe support using the fastener connecting method, a fastener connecting structure, and the fastener. The present invention relates to a pipe support having a connection structure.

従来のパイプ支持具は、１組のパイプ支持材をヒンジ結合により回動可能に組み合わせて構成され、それぞれのパイプ支持材の固定部が、外壁に取り付けたパイプ支持具用の取付具に取り付け固定されるようになっている（たとえば、特許文献１参照）。   A conventional pipe support is configured by combining a pair of pipe support materials so as to be rotatable by hinge coupling, and the fixing portions of the pipe support materials are fixedly attached to the pipe support fixtures attached to the outer wall. (For example, refer to Patent Document 1).

具体的には、図４に示すように、パイプ支持具１００を構成するヒンジ結合された２つのパイプ支持材１１０はそれぞれ、バンド部１１１と、挿通孔１１３を有した平板状の固定部１１２とを有しており、これらの固定部１１２、１１２で挿通孔３ａ付きの取付具３を挟持した状態で、挿通孔１１３、３ａ、１１３にボルト１２０を通してナット１２１止めする固定構造となっている。   Specifically, as shown in FIG. 4, the two hinged pipe support members 110 constituting the pipe support 100 are respectively composed of a band portion 111 and a flat plate-like fixing portion 112 having an insertion hole 113. In the state where the fixture 3 with the insertion hole 3a is sandwiched between the fixing portions 112 and 112, the nuts 121 are fixed to the insertion holes 113, 3a and 113 through bolts 120.

ところで、このような止具（ボルト１２０）を用いた固定作業は、作業効率を考慮して、あらかじめ一方の固定部１１２（止具連結対象部）にボルト１２０を脱落防止プレート（不図示）などで仮止めしておき、その後、現場で本固定の作業をすることが一般的である。この脱落防止プレートはプラスチック製の薄いものであるため、ボルト１２０の軸部に取り付けたまま施工してもよく、よって取り外しの手間も不要となる。このような脱落防止プレートは、その他の種々の施工現場においてもボルトの脱落防止目的として多く利用されている。   By the way, in the fixing work using such a fastener (bolt 120), in consideration of work efficiency, the bolt 120 is attached to one fixing portion 112 (fastener connection target portion) in advance and a fall-off prevention plate (not shown) or the like. It is common to temporarily fix it at, and then perform the actual fixing work at the site. Since the drop-off prevention plate is a thin plastic plate, it may be installed while being attached to the shaft portion of the bolt 120, and thus the labor of removal is not required. Such a drop-off prevention plate is often used in various other construction sites for the purpose of preventing bolt drop-off.

また、特許文献２に記載された方法を用いてボルトの脱落防止を図ることも想定できる。この方法は、挿通孔に挿通された止具（ピン）の軸部の周囲に配した固定部材を塑性変形させることで、止具を止具連結対象部（同文献の例では基材）に固着させるようになっている。   It can also be assumed that the bolt is prevented from falling off using the method described in Patent Document 2. In this method, the fixing member disposed around the shaft portion of the stopper (pin) inserted through the insertion hole is plastically deformed, so that the stopper is connected to the stopper connection target portion (base material in the example of the same document). It is designed to be fixed.

しかしながら、脱落防止プレートや特許文献２の固定部材を用いる方法では構成部材が従来に比べ増えるため、部材管理をするうえでデメリットとなる。また、特許文献２に記載の方法では、固定部材を塑性変形させるプレス加工の処理を必要とされるから、コスト高にもなる。   However, in the method using the drop prevention plate or the fixing member of Patent Document 2, the number of constituent members is increased as compared with the conventional method, which is a demerit in managing the members. In addition, the method described in Patent Document 2 requires a pressing process that plastically deforms the fixing member, which increases the cost.

また、作業中のボルトの脱落を防止する他の対策として、圧入によりボルトを挿通孔に係止できるように軸部の根元に圧入部を設けたかしめボルトを用いる方法も想定できるが、この方法によれば、この種のかしめボルトが高価であるためコスト高になることは避けられない。   In addition, as another measure for preventing the bolt from falling off during work, a method using a crimped bolt provided with a press-fit portion at the base of the shaft portion so that the bolt can be locked in the insertion hole by press-fitting can be assumed. Therefore, since this type of caulking bolt is expensive, it is inevitable that the cost will increase.

本発明は、このような事情を考慮して提案されたもので、その目的は、使用する部材が従来に比べ増えることがなく、かつ製造、施工するうえでコスト高となることもなく、止具を脱落しないように止具連結対象部に連結できる止具連結方法、パイプ支持具の製造方法、止具連結構造およびパイプ支持具を提供することにある。   The present invention has been proposed in view of such circumstances, and its purpose is to prevent the increase in the number of members to be used compared to the prior art, without increasing the cost for manufacturing and construction.

以下に、本発明の実施の形態について、添付図面を参照しながら説明する。まず、本止具連結方法の概略について説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings. First, an outline of this fastener connecting method will be described.

本止具連結方法は、止具連結対象部（本実施形態の例では固定部２０）に形成された挿通孔２１に止具（本実施形態の例ではボルト３０）を挿通し、挿通孔２１の周縁部２２をプレス金型４０にてプレス加工して挿通孔２１の内寸法を小さくすることで止具を止具連結対象部に係着連結させる手順である（図２および図３参照）。   The present fastener connecting method inserts a fastener (bolt 30 in the example of the present embodiment) through the insertion hole 21 formed in the fastener connection target portion (fixed portion 20 in the example of the present embodiment), and the insertion hole 21. This is a procedure in which the peripheral edge portion 22 is pressed with a press die 40 to reduce the inner dimension of the insertion hole 21 so that the fastener is fixedly connected to the fastener connection target portion (see FIGS. 2 and 3). .

このような止具連結方法は、たとえばパイプ支持具５の製造方法において用いられる。以下、パイプ支持具５およびその製造方法を例に挙げ、止具連結方法および止具連結構造について、図１〜図４をもとに説明する。   Such a fastener connecting method is used in a method for manufacturing the pipe support 5, for example. Hereinafter, the pipe support 5 and the manufacturing method thereof will be described as examples, and the stopper connection method and the stopper connection structure will be described with reference to FIGS.

パイプ支持具５は、図１（ａ）に示すように、１組のパイプ支持材１０、１０を組み合わせてなる。パイプ支持材１０は、鉄、鋼、ステンレスなどの金属材料などよりなり、パイプ１を抱持するバンド部１１と、挿通孔２１、２１を有した固定部２０とを備えており、固定部２０、２０どうしで取付対象を挟持した状態で、ボルト３０よりなる止具を挿通孔２１に挿通して取付対象に固定されるようになっている。この固定部２０の内面（取付対象を挟持する面）は、挿通孔２１を除く面が平坦面とされる。パイプ支持具５においては、これらの固定部２０、２０のうちの一方の固定部２０が、ボルト３０、３０が連結される上記の止具連結対象部とされる。   The pipe support 5 is formed by combining a pair of pipe support members 10 and 10 as shown in FIG. The pipe support member 10 is made of a metal material such as iron, steel, and stainless steel, and includes a band portion 11 that holds the pipe 1 and a fixing portion 20 having insertion holes 21 and 21. In a state where the object to be attached is sandwiched between 20, a stopper made of a bolt 30 is inserted into the insertion hole 21 and fixed to the object to be attached. The inner surface of the fixing portion 20 (the surface that holds the attachment target) is a flat surface excluding the insertion hole 21. In the pipe support 5, one of the fixing parts 20, 20 is the above-described stopper connection target part to which the bolts 30, 30 are connected.

ここで、取付対象とは、パイプ１を配設するためのパイプ支持具５を外壁に沿って取り付けるための、外壁に固定された取付具３である。取付具３は平板状とされ、そこには両横方向に貫通する、前後に長い長孔３ａが開設されている。この取付具３を２つの固定部２０、２０で挟み、長孔３ａでパイプ支持具５の出具合を調整して、一方の固定部２０の２箇所の挿通孔２１、２１に連結した止具を構成するボルト３０と、他方の固定部２０の挿通孔２１から出たボルト３０の軸部３２に螺合するナット３６とでパイプ支持具５を固定する取付構造となっている。   Here, the attachment target is the fixture 3 fixed to the outer wall for attaching the pipe support 5 for arranging the pipe 1 along the outer wall. The fixture 3 has a flat plate shape, and a long hole 3a extending in the front-rear direction is formed therethrough. The fixture 3 is sandwiched between the two fixing portions 20 and 20, adjusted by the long hole 3 a to adjust the degree of the pipe support 5, and connected to the two insertion holes 21 and 21 of the one fixing portion 20. The pipe support 5 is fixed by the bolt 30 that constitutes the nut 30 and the nut 36 that is screwed into the shaft portion 32 of the bolt 30 that is protruded from the insertion hole 21 of the other fixing portion 20.

本実施形態では、施工時においては、図１（ａ）に示すように、すでに一方の固定部２０にボルト３０が係着連結されている。ボルト３０が連結した固定部２０の軸部突出側（内面側）は、図１（ｂ）の部分斜視図のようになっている。すなわち、図１（ｂ）に示すように、たとえば直径が約５ｍｍのボルト３０を用いた場合、ボルト３０を連結した固定部２０の軸部側では、挿通孔２１の周縁部２２に、幅０．１〜０．５ｍｍ程度の環状溝状部（凹み）が形成されている。固定部２０の内面は、ボルト３０の連結前の状態では挿通孔２１を除き凹凸なく平坦な面となっているが、ボルト３０を連結させた後では、周縁部２２が段差を介した溝状環状部に変形している。   In this embodiment, at the time of construction, as shown in FIG. 1A, the bolt 30 is already engaged and connected to the one fixing portion 20. The shaft portion protruding side (inner surface side) of the fixed portion 20 to which the bolt 30 is connected is as shown in the partial perspective view of FIG. That is, as shown in FIG. 1B, for example, when a bolt 30 having a diameter of about 5 mm is used, a width 0 is provided at the peripheral portion 22 of the insertion hole 21 on the shaft portion side of the fixing portion 20 to which the bolt 30 is connected. An annular groove (dent) of about 1 to 0.5 mm is formed. The inner surface of the fixing portion 20 is a flat surface without unevenness except for the insertion hole 21 in a state before the bolt 30 is connected, but after the bolt 30 is connected, the peripheral portion 22 is a groove-like shape through a step. It is deformed into an annular part.

その周縁部２２は、図１（ｂ）に示すように、周縁部２２とその外側を区別するように円形が表れている。この円形は、段差の角部２３（図１（ｂ）の拡大縦断面図）が表面に表れたものである。また、周縁部２２の内部（角部２３とボルト３０の軸部３２との間）は他の面よりも凹んでおり、その凹み空間の中で軸部側に突出した膨出部２４が形成されている。膨出部２４の表面側は、図１（ｂ）の例では丸くなっているが、これには限らず、図１（ｃ）のように凹湾曲したものでもよく、図１（ｄ）のように凹凸形状のものでもよい。この表面側の形状は、図２の説明において後述するプレス金型４０の形状や押圧の程度によっておおむね定まる。   As shown in FIG. 1B, the peripheral edge 22 has a circular shape so as to distinguish the peripheral edge 22 from the outside. This circular shape has a stepped corner 23 (enlarged longitudinal sectional view of FIG. 1B) appearing on the surface. Further, the inside of the peripheral edge portion 22 (between the corner portion 23 and the shaft portion 32 of the bolt 30) is recessed from the other surface, and a bulging portion 24 protruding toward the shaft portion side is formed in the recessed space. Has been. The surface side of the bulging portion 24 is rounded in the example of FIG. 1B, but is not limited thereto, and may be concavely curved as shown in FIG. 1C, as shown in FIG. As shown in FIG. The shape on the surface side is generally determined by the shape of the press die 40 and the degree of pressing described later in the description of FIG.

これらの図例では、膨出部２４が軸部３２のねじ山３３、３３間（ねじ溝３４）にしっかりと嵌り込んでおり、それにより、ボルト３０は固定部２０に固着された状態（ボルト３０が固定部２０に対して動かない状態）となっている。しかしながら、このような係着には限定されず、図２および図３（特に図３（ｂ）参照）に示すように、膨出部２４がボルト３０の軸部３２のねじ溝３４に遊嵌状態となってボルト３０が係着されるものであってもよい。すくなくとも、ボルト３０が軸部方向へ移動しない程度の係着構造とされることが望ましい。なお、遊嵌状態の場合には、ボルト３０の軸部３２が軸回りに回転できることが、パイプ支持具５を取付具３に取り付けるためのボルト止め作業をするうえで望ましい。   In these examples, the bulging portion 24 is firmly fitted between the screw threads 33 and 33 (screw groove 34) of the shaft portion 32, whereby the bolt 30 is fixed to the fixing portion 20 (bolt 30 is in a state in which it does not move with respect to the fixed portion 20). However, the engagement is not limited to such engagement, and the bulging portion 24 is loosely fitted in the thread groove 34 of the shaft portion 32 of the bolt 30 as shown in FIGS. The bolt 30 may be engaged in a state. At least, it is desirable that the engagement structure is such that the bolt 30 does not move in the axial direction. In the loose fitting state, it is desirable that the shaft portion 32 of the bolt 30 can rotate around the axis in order to perform the bolting operation for attaching the pipe support 5 to the attachment 3.

このパイプ支持具５に採用される止具連結構造は、ボルト３０よりなる止具が挿通孔２１に挿通された状態で挿通孔２１の周縁部２２がプレス加工されることで挿通孔２１の内寸法が小さくなった止具連結対象部（固定部２０）に係着連結されてなるものでる。このプレス加工は金型を用いてなされる。   The stopper connecting structure employed in the pipe support 5 is such that the peripheral portion 22 of the insertion hole 21 is pressed in a state in which the stopper made of the bolt 30 is inserted into the insertion hole 21, so that the inner portion of the insertion hole 21 is pressed. It is engaged and connected to a stopper connection target portion (fixed portion 20) whose size is reduced. This pressing is performed using a mold.

ついで、金型を用いた具体的な止具連結方法（を用いたパイプ支持具の製造方法）について、図２および図３をもとに説明する。   Next, a specific stopper connecting method using a mold (a method for manufacturing a pipe support using the die) will be described with reference to FIGS.

まず、ボルト３０が係着連結される一方のパイプ支持材１０を用意する。このパイプ支持材１０は、パイプ支持材１０どうしをヒンジ結合する前のものであり、バンド部１１が形成される前のバンド部１１部分が湾曲していない平板帯板状のものであってもよいし、バンド部１１が形成された後のバンド部１１部分が湾曲したものであってもよい。金型としては、プレス金型４０と載置台５０とを用いる。   First, one pipe support material 10 to which the bolt 30 is engaged and connected is prepared. This pipe support material 10 is a thing before the pipe support materials 10 are hinge-coupled, and even if the band part 11 part before the band part 11 is formed is a flat belt-like plate shape which is not curved. Alternatively, the band portion 11 after the band portion 11 is formed may be curved. As the mold, a press mold 40 and a mounting table 50 are used.

載置台５０は、図２（ａ）に示すように、ボルト３０の頭部３１が収容される、上方に向け開口した凹部５１、５１が、固定部２０の２つの挿通孔２１、２１の位置関係に対応して設けられた台である。この凹部５１はボルト３０の頭部３１がずれない程度に、頭部３１の大きさにおおむね合致したものとされることが望ましい。その載置台５０に、凹部５１、５１に頭部３１、３１が収容されるように軸部３２、３２を上に向けたボルト３０、３０をセットする。そして、軸部３２、３２の上方から、固定部２０の挿通孔２１、２１に軸部３２、３２が通るようにパイプ支持材１０をセットする（以上、図２（ａ）参照）。   As shown in FIG. 2 (a), the mounting table 50 has recesses 51, 51 opened upward, in which the heads 31 of the bolts 30 are accommodated, and the positions of the two insertion holes 21, 21 of the fixing unit 20. It is a stand provided corresponding to the relationship. It is desirable that the concave portion 51 is substantially matched with the size of the head portion 31 so that the head portion 31 of the bolt 30 is not displaced. On the mounting table 50, bolts 30, 30 with the shaft portions 32, 32 facing upward are set so that the head portions 31, 31 are accommodated in the recesses 51, 51. Then, the pipe support member 10 is set from above the shaft portions 32 and 32 so that the shaft portions 32 and 32 pass through the insertion holes 21 and 21 of the fixed portion 20 (see FIG. 2A).

プレス金型４０は、図２（ｂ）に示すように、下方に突出した２つの突状成形部４１、４１が、載置台５０の２つの凹部５１、５１に対応して設けられた金型である。この突状成形部４１、４１は底面視でリング状とされ、その開口は上方に向けて円柱状に貫通している。また、突状成形部４１の側面視形状は円錐台とされる。ようするに、この突状成形部４１は、挿通孔２１の形状に合致するように円形のリング状に突出し、側面視で山形状をなしている。なお、本プレス金型４０はその先端で挿通孔２１の周縁部２２をプレス加工するものであるためリング状をなしているが、全体形状は円錐台形状でなくてもよい。   As shown in FIG. 2 (b), the press mold 40 has a mold in which two projecting portions 41 and 41 projecting downward are provided corresponding to the two recesses 51 and 51 of the mounting table 50. It is. The projecting portions 41 and 41 are ring-shaped when viewed from the bottom, and the opening penetrates upward in a columnar shape. Further, the side-view shape of the protrusion-shaped part 41 is a truncated cone. Thus, the projecting shaped portion 41 protrudes in a circular ring shape so as to match the shape of the insertion hole 21 and has a mountain shape in a side view. In addition, since this press metal mold | die 40 presses the peripheral part 22 of the penetration hole 21 in the front-end | tip, it has comprised the ring shape, However, The whole shape does not need to be a truncated cone shape.

突状成形部４１の先端のリング部４２の厚さの寸法は、周縁部２２の幅寸法におおむね対応した寸法とされる。この突状成形部４１の先端が挿通孔２１の周縁部２２に対して押圧する部位である。このプレス金型４０を、リング部４２（貫通孔４３）と軸部３２の位置とを位置合わせして上方よりプレスする（図２（ｂ）参照）。   The dimension of the thickness of the ring part 42 at the tip of the protrusion-shaped part 41 is a dimension that roughly corresponds to the width dimension of the peripheral edge part 22. The tip of the protruding molded part 41 is a part that presses against the peripheral part 22 of the insertion hole 21. The press die 40 is pressed from above by aligning the ring portion 42 (through hole 43) and the position of the shaft portion 32 (see FIG. 2B).

図３（ａ）は、プレス金型４０の先端のリング部４２が周縁部２２に当接したときの状態図である。押圧の程度としては、本例の場合、周縁部２２が約０．１ｍｍ凹む程度であり、そのように押圧した結果、周縁部２２は図３（ｂ）の拡大図のように変形する。   FIG. 3A is a state diagram when the ring portion 42 at the tip of the press die 40 contacts the peripheral edge portion 22. In this example, the degree of pressing is such that the peripheral edge 22 is recessed by about 0.1 mm. As a result of such pressing, the peripheral edge 22 is deformed as shown in the enlarged view of FIG.

このようなプレス加工の結果、周縁部２２には凹みによる溝状環状部が形成され、その溝状環状部内では、固定部２０の材料が挿通孔２１の円中心に向かうように塑性変形して膨出部２４が形成される。つまり、このプレスの結果、挿通孔２１の内寸法（内径寸法）は縮小する。   As a result of such pressing, a groove-like annular portion is formed in the peripheral edge portion 22, and in the groove-like annular portion, the material of the fixing portion 20 is plastically deformed toward the circle center of the insertion hole 21. A bulging portion 24 is formed. That is, as a result of this pressing, the inner dimension (inner diameter dimension) of the insertion hole 21 is reduced.

図３（ｃ）は、挿通孔２１とその周縁部２２の平面図であり、図中、Ｓ１はプレス加工前の周縁部２２の幅寸法であり、Ｓ２はプレス加工により膨出部２４が内側に突出した後の周縁部２２の幅寸法である。このようにプレスによって、挿通孔２１の（表面側の）内径寸法は縮小する。   FIG. 3C is a plan view of the insertion hole 21 and its peripheral edge portion 22, in which S <b> 1 is the width dimension of the peripheral edge portion 22 before press working, and S <b> 2 is the inside of the bulging portion 24 by press working. It is the width dimension of the peripheral part 22 after protruding in the direction. Thus, the inner diameter dimension (on the front surface side) of the insertion hole 21 is reduced by the press.

そして、膨出部２４の軸部３２側の端部はボルト３０のねじ山３３に引っ掛かり、ねじ溝３４に遊嵌した状態となる。すなわち、この状態ではボルト３０は挿通孔２１に対し、軸方向には移動不可であるが、回転可能な状態となっている。   The end portion of the bulging portion 24 on the shaft portion 32 side is caught by the thread 33 of the bolt 30 and is loosely fitted in the screw groove 34. That is, in this state, the bolt 30 is not movable in the axial direction with respect to the insertion hole 21 but is rotatable.

このように、金型（プレス金型４０）を用いた止具連結方法を用いることにより、ボルト３０は固定部２０の挿通孔２１に脱落不可の状態に係着連結されることとなる。したがって、パイプ支持具５を施工する際にはボルト３０が脱落するおそれがなく、作業がしやすくなる。また、脱落防止プレートなど他の部材を必要としない。このように従来に比べ部材が増えないため、製品コストが高くなることはない。   In this way, by using a fastener connecting method using a mold (press mold 40), the bolt 30 is fixedly connected to the insertion hole 21 of the fixing portion 20 in a state where it cannot be dropped off. Therefore, when constructing the pipe support 5, there is no fear that the bolt 30 will drop off, and the operation will be easy. Further, no other member such as a drop-off prevention plate is required. Thus, since the number of members does not increase as compared with the conventional case, the product cost does not increase.

また、図３（ｂ）に示すように、ボルト３０が回転する程度の係着であれば、他の固定部２０（図１（ａ）参照）側でナット３６を螺合する際に、ボルト３０を回転操作することができ、従来どおりの施工作業を行うことができる。もちろん、ボルト３０は固定部２０に固着されてもよく、その場合でもナット３６を回転操作すればよいので、ほとんど問題はない。   Further, as shown in FIG. 3B, when the bolt 30 is engaged so as to rotate, the bolt 36 is screwed when the nut 36 is screwed on the other fixing portion 20 (see FIG. 1A) side. 30 can be rotated and construction work can be performed as usual. Of course, the bolt 30 may be fixed to the fixing portion 20, and even in that case, the nut 36 only needs to be rotated, so there is almost no problem.

さらに本実施形態では、挿通孔２１（周縁部２２）の形状に合致した平面視円形リング状の突状成形部４１を有したプレス金型４０を用いているため、リング部４２により周縁部２２を均一に押圧でき、ボルト３０の軸部３２を歪んだ状態に取り付けることを回避することができ、スムーズな施工作業を実施することができる。なお、プレス金型４０としては、周縁部２２の一部（たとえば４箇所）を押圧するような形状であってもよい。   Furthermore, in this embodiment, since the press die 40 having the projecting shaped part 41 having a circular ring shape in plan view that matches the shape of the insertion hole 21 (peripheral part 22) is used, the peripheral part 22 is formed by the ring part 42. Can be pressed uniformly, and it can avoid attaching the axial part 32 of the volt | bolt 30 in the distorted state, and can implement a smooth construction operation. The press die 40 may have a shape that presses a part (for example, four places) of the peripheral edge portion 22.

また、挿通孔２１が長孔である場合、その周縁部のうち長孔の短手方向の部位を押圧することで、長孔においてもボルト３０を係着することができる。もちろん、長孔の全周周縁部を押圧するようにしてもよい。   Moreover, when the insertion hole 21 is a long hole, the volt | bolt 30 can be engaged also in a long hole by pressing the site | part of the transversal direction of a long hole among the peripheral parts. Of course, you may make it press the perimeter edge part of a long hole.

また、１列に複数のボルト３０の頭部３１を収容できるように、凹部５１、５１の代わりに２列の凹溝を載置台に設けるようにしてもよい。このような載置台を用いれば複数のパイプ支持材１０を並べて配置でき、複数のプレス金型４０を用いて、あるいは１つのプレス金型４０を用いて順々にプレス加工することができる。   Further, two rows of concave grooves may be provided on the mounting table instead of the concave portions 51, 51 so that the heads 31 of the plurality of bolts 30 can be accommodated in one row. By using such a mounting table, a plurality of pipe support members 10 can be arranged side by side, and can be pressed in sequence using a plurality of press dies 40 or a single press dies 40.

さらに、本実施形態のプレス加工では載置台５０が用いてあるが、これの代わりにボルト３０の頭部３１を固定する他の固定手段を用いてもよい。また、プレス金型４０を下方より上方に移動させてプレス加工するようにしてもよい。   Furthermore, although the mounting table 50 is used in the press working of the present embodiment, other fixing means for fixing the head portion 31 of the bolt 30 may be used instead. Alternatively, the press mold 40 may be moved from below to above for press working.

また、パイプ支持材１０のバンド部１１の成形は、ボルト３０の連結のための上記止具連結工程の前または後になされればよいが、止具連結工程と同時になされるようにしてもよい。たとえば、止具連結構造を成形でき、かつバンド部１１も成形できるプレス金型を用いてもよい。   In addition, the band portion 11 of the pipe support member 10 may be formed before or after the fastener connecting step for connecting the bolts 30, but may be performed simultaneously with the stopper connecting step. For example, you may use the press metal mold | die which can shape | mold a fastener connection structure and can also shape | mold the band part 11. FIG.

以上では、ボルト３０よりなる止具を固定部２０（止具連結対象部）に連結する方法を例示し説明したが、リベットよりなる止具を止具連結対象部に連結することも可能である。リベットを挿通孔２１の周縁部２２に係着させるためには、リベットの外周面に、周縁部２２に塑性変形させた膨出部２４を当接させることが望ましい。つまり、リベットの抜けを回避するためには、リベットが止具連結対象部に固着連結されることが望ましい。なお、リベットの外周面に膨出部２４が引っ掛かる凹凸を設ければ、ボルト３０の場合と同様に、リベットを回転可能な状態に止具連結対象部に連結することも可能である。   In the above, the method of connecting the fastener made of the bolt 30 to the fixing portion 20 (stopper connection target portion) has been illustrated and described. However, it is also possible to connect the stopper made of rivets to the stop connection target portion. . In order to engage the rivet with the peripheral portion 22 of the insertion hole 21, it is desirable to bring the bulging portion 24 plastically deformed into the peripheral portion 22 into contact with the outer peripheral surface of the rivet. That is, in order to avoid the rivet from coming off, it is desirable that the rivet is fixedly connected to the stopper connection target portion. In addition, if the unevenness | corrugation which the bulging part 24 catches in the outer peripheral surface of a rivet is provided, it is also possible to connect a rivet to a fastener connection object part in the state which can be rotated similarly to the case of the volt | bolt 30.
