Description
本開示は、配線保護構造に関する。 This disclosure relates to a wiring protection structure.
従来、鉄骨梁などの板状の金属材に穴を穿ち配線を通す場合、配線が金属材の穴と接触して傷付くのを防止するために、穴の内周に樹脂などにより形成された保護カバーを装着することが知られている（例えば、特許文献１）。 Conventionally, when drilling holes in plate-shaped metal materials such as steel beams to pass wiring through, it is known to attach a protective cover made of resin or the like to the inner circumference of the hole to prevent the wiring from coming into contact with the hole in the metal material and being damaged (for example, Patent Document 1).
この従来技術では、保護カバーは、外環体と内筒体とを備える。そして、外環体を金属材の穴に対し、一方の開口からもう一方の開口の外側に突出するまで差し込み、その後、外環体の内側に内筒体を差し込み、外環体のもう一方の開口から突出した部分を拡径させて抜け止め状態として、保護カバーを穴の内周に固定するようになっている。 In this conventional technology, the protective cover comprises an outer ring body and an inner cylinder body. The outer ring body is inserted into a hole in a metal material from one opening until it protrudes outward from the other opening, and then the inner cylinder body is inserted inside the outer ring body, and the part of the outer ring body protruding from the other opening is expanded in diameter to prevent it from coming loose, thereby fixing the protective cover to the inner circumference of the hole.
しかしながら、上述の従来技術では、保護カバーを、金属材の穴の一方の開口からもう一方の開口に突出させて拡径させるため、金属材の穴のもう一方の開口に接して他の部材が存在する場合、配線保護部材を穴に装着できなかった。 However, in the above-mentioned conventional technology, the protective cover is expanded by protruding from one opening of the hole in the metal material to the other opening, so if another component is present in contact with the other opening of the hole in the metal material, the wiring protective component cannot be attached to the hole.
そこで、本開示は、配線を挿通させる金属材の配線挿通用穴の開口に接して部材が設けられていても、配線の保護が可能な配線保護構造を提供することを目的としている。 The present disclosure therefore aims to provide a wiring protection structure that can protect wiring even if a member is provided in contact with the opening of a wiring insertion hole in a metal material through which the wiring passes.
本開示の配線保護構造は、板状の金属材に開口された配線挿通用穴に挿通された配線を前記配線挿通用穴から保護する配線保護部材を用いた配線保護構造である。前記配線保護部材は、板状の本体と、前記本体に貫通して形成され、前記配線挿通用穴よりも小径の貫通穴と、前記貫通穴の内周縁部を内径方向に突出した湾曲状に形成された曲面部と、を備える。そして、前記配線保護部材の前記貫通穴を前記配線挿通用穴に対して径方向で内側に配置するとともに、前記本体を前記金属材の一方の面に当接させた状態で前記配線保護部材が前記金属材に固定され、
前記配線保護部材は、前記曲面部が、前記貫通穴の内周部を、前記本体の表裏面の一方である第１の面の方向に折曲した形状の折曲部により形成され、かつ、前記折曲部の前記第１の面からの突出代は、前記配線挿通用穴の軸方向寸法以下に形成され、
前記折曲部を、前記配線挿通用穴に挿入して、前記貫通穴を前記配線挿通用穴の内側に配置し、前記本体を前記金属材の一方の面に当接させた状態で前記配線保護部材が前記金属材に固定されている配線保護構造とした。
The wiring protection structure of the present disclosure is a wiring protection structure using a wiring protection member that protects wiring inserted through a wiring insertion hole opened in a plate-shaped metal material from the wiring insertion hole. The wiring protection member includes a plate-shaped main body, a through hole formed through the main body and having a smaller diameter than the wiring insertion hole, and a curved surface portion formed in a curved shape that protrudes an inner peripheral edge portion of the through hole in an inward radial direction. The through hole of the wiring protection member is disposed radially inward from the wiring insertion hole, and the wiring protection member is fixed to the metal material with the main body abutting against one surface of the metal material ,
the wiring protection member is formed by a bent portion having a shape in which an inner periphery of the through hole is bent toward a first surface which is one of the front and rear surfaces of the main body, and a protrusion of the bent portion from the first surface is formed to be equal to or smaller than an axial dimension of the wiring insertion hole,
The bent portion is inserted into the wiring insertion hole, the through hole is positioned inside the wiring insertion hole, and the main body is abutted against one side of the metal material, resulting in a wiring protection structure in which the wiring protection member is fixed to the metal material .
本開示の配線保護構造では、配線保護部材の貫通穴を金属材の配線挿通用穴の径方向で内側に配置した上で、本体の第１の面を、金属材の一方の面に当接させた状態とし、配線保護部材を金属板に固定した配線保護構造とすることができる。したがって、配線挿通用穴の配線保護部材を固定した側とは反対側の開口に接して他の部材が存在していても、配線保護部材を固定することができる。 In the wiring protection structure disclosed herein, the through hole of the wiring protection member is disposed radially inward of the wiring insertion hole of the metal material, and the first surface of the main body is placed in contact with one surface of the metal material, resulting in a wiring protection structure in which the wiring protection member is fixed to the metal plate. Therefore, even if another member is present in contact with the opening on the opposite side of the wiring insertion hole to the side where the wiring protection member is fixed, the wiring protection member can be fixed.
さらに、本開示の配線保護構造では、配線を金属材の配線挿通用穴に挿通させる際は、配線が配線挿通用穴に対して径方向に変位した場合、配線挿通用穴よりも小径の貫通穴の内周に当接することにより、配線が配線挿通用穴の内周に接触して傷付くのを抑制できる。また、貫通穴の内周には曲面部が形成されているため、配線が貫通穴に接触した際に配線が傷付くのも抑制できる。
そして、折返部を配線挿通用穴に挿入することにより、貫通穴および本体の位置決めを容易に行うことができる。また、配線保護部材に外力が作用して貫通穴の径方向へ移動しようとした際には、折返部が配線挿通用穴の内周と係合して移動が規制される。
Furthermore, in the wire protection structure of the present disclosure, when the wire is inserted into the wire insertion hole of the metal material, if the wire is displaced in the radial direction relative to the wire insertion hole, the wire comes into contact with the inner periphery of the through hole, which has a smaller diameter than the wire insertion hole, thereby preventing the wire from coming into contact with the inner periphery of the wire insertion hole and being damaged. Also, since the inner periphery of the through hole has a curved portion, it is possible to prevent the wire from being damaged when it comes into contact with the through hole.
The wire protection member is provided with a bent portion and a bent part that is bent into the through hole. The bent portion is inserted into the through hole, so that the position of the through hole and the main body can be easily determined. When an external force acts on the wire protection member and the wire protection member attempts to move in the radial direction of the through hole, the bent portion engages with the inner circumference of the wire insertion hole to restrict the movement.
以下、本開示の実施の形態について図面を参照して説明する。
（実施の形態１）
実施の形態１の配線保護構造は、図１に示す建物Ｈの天井部分囲に適用されている。
Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
(Embodiment 1)
The wiring protection structure of the first embodiment is applied to the ceiling portion of a building H shown in FIG.
この建物Ｈの天井部分には、鉄骨梁１が設けられている。この鉄骨梁１は、側板１ａの上下に上フランジ１ｂおよび下フランジ１ｃを一体に備えるコの字断面形状に形成されている。 A steel beam 1 is installed in the ceiling of this building H. This steel beam 1 is formed into a U-shaped cross section with an upper flange 1b and a lower flange 1c integrally formed above and below the side plate 1a.
また、鉄骨梁１の金属材としての下フランジ１ｃの下面に当接して、下フランジ１ｃの略全長に亘り木桟２が設けられている。 In addition, a wooden crosspiece 2 is provided over almost the entire length of the lower flange 1c, which is a metal material of the steel beam 1, in contact with the underside of the lower flange 1c.
この木桟２は、木製の天井パネル３および間仕切５を、木製部材同士の結合により鉄骨梁１に固定するために設けられた部材である。なお、天井パネル３の上方部分は、上階の床あるいは屋根との間に形成された天井裏空間４となっている。また、間仕切５は、胴縁５ａを挟んで、一対の壁材５ｂ，５ｃが対向して設けられ、壁材５ｂ，５ｃの間には、壁空間５ｄが形成されている。そして、胴縁５ａが木桟２に固定されている。 The wooden battens 2 are members provided to secure the wooden ceiling panel 3 and partition 5 to the steel beams 1 by joining the wooden members together. The upper part of the ceiling panel 3 forms an attic space 4 between it and the floor or roof of the upper floor. The partition 5 also has a pair of wall materials 5b, 5c facing each other with a furring strip 5a in between, and a wall space 5d is formed between the wall materials 5b, 5c. The furring strip 5a is then fixed to the wooden battens 2.
天井裏空間４から壁空間５ｄに亘って、配線２０が配索されている。すなわち、鉄骨梁１の下フランジ１ｃと木桟２とには、それぞれ、配線挿通用穴１ｄ、２ｄhが、同軸に配置して形成されている。なお、配線挿通用穴１ｄ、２ｄは、下フランジ１ｃの上方から同時に穿設するため、同径の寸法に形成されている。そして、配線２０は、下フランジ１ｃおよび木桟２の配線挿通用穴１ｄ，２ｄ（図２参照）に挿通されて、天井裏空間４と壁空間５ｄとに跨って配索されている。 Wiring 20 is routed from the ceiling space 4 to the wall space 5d. That is, wiring insertion holes 1d, 2dh are formed coaxially in the lower flange 1c of the steel beam 1 and the wooden batten 2, respectively. Note that wiring insertion holes 1d, 2d are formed with the same diameter because they are drilled simultaneously from above the lower flange 1c. Wiring 20 is then inserted through wiring insertion holes 1d, 2d (see Figure 2) in the lower flange 1c and the wooden batten 2, and routed across the ceiling space 4 and the wall space 5d.
配線２０を、鉄骨梁１の下フランジ１ｃの配線挿通用穴１ｄを挿通させるにあたり、実施の形態１の配線保護部材１０を用いた配線保護構造が適用されている。すなわち、この配線保護構造は、下フランジ１ｃの配線挿通用穴１ｄの下方の開口に隣接して、木桟２が設けられており、従来の保護カバーを設けることができない部位に適用する配線保護構造である。 When wiring 20 is inserted through wiring insertion hole 1d in lower flange 1c of steel beam 1, a wiring protection structure using wiring protection member 10 of embodiment 1 is applied. In other words, this wiring protection structure has wooden crosspiece 2 provided adjacent to the lower opening of wiring insertion hole 1d in lower flange 1c, and is a wiring protection structure that is applied to a portion where a conventional protective cover cannot be provided.
以下に、実施の形態１の配線保護部材１０を用いた配線保護構造について詳細に説明する。 The following describes in detail the wiring protection structure using the wiring protection member 10 of embodiment 1.
配線保護部材１０は、金属板により、図３（ｂ）に示すように、四隅の角部を丸めた略長方形の平面形状に形成された本体１０ａと、本体１０ａの中央に円形に貫通された貫通穴１１と、を備える。 The wiring protection member 10 includes a main body 10a made of a metal plate and formed in a generally rectangular planar shape with rounded corners as shown in FIG. 3(b), and a circular through hole 11 that penetrates the center of the main body 10a.
また、貫通穴１１の内周は、ヘミング加工により、図３（ａ）に示すように表裏の一方である第１の面１０１の方向に立ち上げ、さらに、貫通穴１１の外周方向に折り返された折返部１２が形成されている。この折返部１２の折返しにより内径方向に突出した湾曲状の曲面部１２ａが形成され、この曲面部１２ａの内径方向への頂点により貫通穴１１の内周が形成されている。なお、以下の説明において配線保護部材の第１の面１０１の反対側の面は、第２の面１０２と称する。 The inner circumference of the through hole 11 is raised toward the first surface 101, which is one of the front and back surfaces, by hemming as shown in FIG. 3(a), and is further folded back toward the outer circumference of the through hole 11 to form a folded portion 12. The folding back of this folded portion 12 forms a curved surface portion 12a that protrudes in the inner diameter direction, and the inner circumference of the through hole 11 is formed by the apex of this curved surface portion 12a in the inner diameter direction. In the following description, the surface of the wiring protection member opposite the first surface 101 is referred to as the second surface 102.
そして、折返部１２曲面の頂点により形成される貫通穴１１の内径ｄ１は、下フランジ１ｃおよび木桟２に形成された配線挿通用穴１ｄ，２ｄの内径よりも小径に形成されている。 The inner diameter d1 of the through hole 11 formed by the apex of the curved surface of the folded portion 12 is smaller than the inner diameters of the wiring insertion holes 1d, 2d formed in the lower flange 1c and the wooden crosspiece 2.
さらに、折返部１２の先端面により形成される先端外径ｄ２は、鉄骨梁１の下フランジ１ｃの配線挿通用穴１ｄの内径と略同寸法に形成され、折返部１２の先端外径ｄ２が配線挿通用穴１ｄの内周に嵌るように形成されている（図２参照）。 Furthermore, the tip outer diameter d2 formed by the tip surface of the folded portion 12 is formed to be approximately the same dimension as the inner diameter of the wiring insertion hole 1d in the lower flange 1c of the steel beam 1, and the tip outer diameter d2 of the folded portion 12 is formed to fit within the inner circumference of the wiring insertion hole 1d (see Figure 2).
配線保護部材１０において、貫通穴１１を間に挟んで、長手方向の両側には、二点鎖線により示す一対のねじ穴１３，１３を形成することができる。ここで、実施の形態１の配線保護部材１０は、ねじ穴１３，１３は、形成されておらず、一方、後述する実施の形態２の配線保護部材２１０、一対のねじ穴１３，１３が形成されているものとする。 In the wiring protection member 10, a pair of screw holes 13, 13 shown by two-dot chain lines can be formed on both sides of the longitudinal direction, sandwiching the through hole 11. Here, the wiring protection member 10 of the first embodiment does not have the screw holes 13, 13 formed therein, whereas the wiring protection member 210 of the second embodiment described below has a pair of screw holes 13, 13 formed therein.
配線保護部材１０は、第１の面１０１を下にして、下フランジ１ｃの上に重ね、配線保護部材１０の貫通穴１１を、下フランジ１ｃの配線挿通用穴１ｄと略同軸に配置されている。このとき、折返部１２の先端面を、図２（ｂ）に示すように、配線挿通用穴１ｄの内周に当接させる。これにより、配線保護部材１０の貫通穴１１を配線挿通用穴１ｄと同軸に容易に配置することができるとともに、配線挿通用穴１ｄの内周面を完全に覆うことができる。 The wiring protection member 10 is placed on the lower flange 1c with the first surface 101 facing down, and the through hole 11 of the wiring protection member 10 is arranged approximately coaxially with the wiring insertion hole 1d of the lower flange 1c. At this time, the tip surface of the folded portion 12 is abutted against the inner circumference of the wiring insertion hole 1d, as shown in FIG. 2(b). This makes it possible to easily arrange the through hole 11 of the wiring protection member 10 coaxially with the wiring insertion hole 1d, and to completely cover the inner circumference of the wiring insertion hole 1d.
さらに、配線保護部材１０は、下フランジ１ｃに固定されている。この配線保護部材１０の固定は、粘着固定テープ３０により行う。すなわち、第１の面１０１を下にして下フランジ１ｃ（図１、図２参照）の上に配置した配線保護部材１０の第２の面１０２およびその周囲の下フランジ１ｃの上面に、図４に示す粘着固定テープ３０の接着面を重ね、配線保護部材１０を下フランジ１ｃに固定している。 Furthermore, the wiring protection member 10 is fixed to the lower flange 1c. This wiring protection member 10 is fixed using an adhesive fixing tape 30. That is, the adhesive surface of the adhesive fixing tape 30 shown in FIG. 4 is superimposed on the second surface 102 of the wiring protection member 10, which is placed on the lower flange 1c (see FIG. 1 and FIG. 2) with the first surface 101 facing down, and on the upper surface of the lower flange 1c around it, thereby fixing the wiring protection member 10 to the lower flange 1c.
なお、粘着固定テープ３０は、貫通穴１１の上に重ねられる位置に、十字の切れ込み３１を形成し、配線２０を挿通する際の目印とするとともに、配線２０の挿通を容易としている。 In addition, the adhesive fixing tape 30 has a cross-shaped notch 31 formed at a position where it overlaps the through hole 11, which serves as a guide when inserting the wiring 20 and makes it easier to insert the wiring 20.
天井裏空間４の配線２０は、以上のようにして固定された配線保護部材１０の貫通穴１１から、さらに、下フランジ１ｃの配線挿通用穴１ｄおよび木桟２の配線挿通用穴２ｄを挿通させて、壁空間５ｄへと配索させる。 The wiring 20 in the attic space 4 is routed from the through hole 11 of the wiring protection member 10 fixed in the above manner, through the wiring insertion hole 1d in the lower flange 1c and the wiring insertion hole 2d in the wooden beam 2, and into the wall space 5d.
この配索の際に、貫通穴１１の内周は、折返部１２の曲面部１２ａが配置されているため、配線２０が、この貫通穴１１の内周（曲面部１２ａ）に接触しても、配線２０を傷付けることがない。また、貫通穴１１の内径ｄ１が、下フランジ１ｃおよび木桟２の配線挿通用穴１ｄ，２ｄよりも小径となっているため、配線２０が、外径方向に変位した際に、まず、貫通穴１１の内周の曲面部１２ａに接触し、配線２０が配線挿通用穴１ｄ、２ｄに接触するのを抑制する。 During this wiring, the curved surface 12a of the folded portion 12 is disposed on the inner periphery of the through hole 11, so even if the wiring 20 comes into contact with the inner periphery (curved surface 12a) of the through hole 11, the wiring 20 will not be damaged. Also, since the inner diameter d1 of the through hole 11 is smaller than the diameter of the wiring insertion holes 1d, 2d of the lower flange 1c and the wooden crosspiece 2, when the wiring 20 is displaced in the outward radial direction, it first comes into contact with the curved surface 12a on the inner periphery of the through hole 11, preventing the wiring 20 from coming into contact with the wiring insertion holes 1d, 2d.
さらに、下フランジ１ｃの配線挿通用穴１ｄの内周は、配線保護部材１０の折返部１２により覆われているため、配線２０が、配線挿通用穴１ｄに、直接接触することを防止できる。また、折返部１２は、水平方向で下フランジ１ｃの配線挿通用穴１ｄの内周に係合しているため、配線２０が配線保護部材１０の貫通穴１１の内周に対して、外径方向に強く接触したとしても、配線保護部材１０が貫通穴１１の外径方向に移動するのを防止できる。よって、配線保護部材１０が移動して、配線２０が配線挿通用穴１ｄの内周に接触するのを防止できる。 Furthermore, since the inner circumference of the wire insertion hole 1d of the lower flange 1c is covered by the folded portion 12 of the wire protection member 10, the wire 20 can be prevented from directly contacting the wire insertion hole 1d. Also, since the folded portion 12 is horizontally engaged with the inner circumference of the wire insertion hole 1d of the lower flange 1c, even if the wire 20 strongly contacts the inner circumference of the through hole 11 of the wire protection member 10 in the outer diameter direction, the wire protection member 10 can be prevented from moving in the outer diameter direction of the through hole 11. Therefore, it is possible to prevent the wire protection member 10 from moving and the wire 20 from contacting the inner circumference of the wire insertion hole 1d.
（実施の形態１の効果）
（１）実施の形態１の配線保護構造では、配線保護部材１０は、板状の金属材としての鉄骨梁１の下フランジ１ｃに開口された配線挿通用穴１ｄに挿通された配線２０を配線挿通用穴１ｄの内周に対して保護する。この配線保護部材１０は、板状の本体１０ａと、本体１０ａに貫通して形成され、配線挿通用穴１ｄよりも小径の貫通穴１１と、貫通穴１１の内周縁部を内径方向に突出した湾曲状に形成された曲面部１２ａと、を備える。そして、本体１０ａの第１の面１０１を下フランジ１ｃの上面に当接させた状態で配線保護部材１０が下フランジ１ｃに固定されている。さらに、折返部１２を、配線挿通用穴１ｄに挿入し、貫通穴１１を配線挿通用穴１ｄの内側に配置している。
(Effects of the First Embodiment)
(1) In the wiring protection structure of the first embodiment, the wiring protection member 10 protects the wiring 20 inserted through the wiring insertion hole 1d opened in the lower flange 1c of the steel beam 1 as a plate-shaped metal material from the inner circumference of the wiring insertion hole 1d. The wiring protection member 10 includes a plate-shaped main body 10a, a through hole 11 formed through the main body 10a and having a smaller diameter than the wiring insertion hole 1d, and a curved surface portion 12a formed in a curved shape that protrudes the inner peripheral edge portion of the through hole 11 in the inner diameter direction. The wiring protection member 10 is fixed to the lower flange 1c with the first surface 101 of the main body 10a abutted against the upper surface of the lower flange 1c. Furthermore, the folded portion 12 is inserted into the wiring insertion hole 1d, and the through hole 11 is disposed inside the wiring insertion hole 1d.
このように、配線保護部材１０は、第１の面１０１を下フランジ１ｃの上面に重ね、配線挿通用穴１ｄを貫通し、取付面の反対側の開口から突出させる部分を有しない。このため、開口に隣接して木桟２が存在していても、配線保護部材１０を取り付け、上記の配線２０の保護を図る配線保護構造とすることができる。 In this way, the wiring protection member 10 overlaps the first surface 101 with the upper surface of the lower flange 1c, penetrates the wiring insertion hole 1d, and does not have a portion that protrudes from the opening on the opposite side of the mounting surface. Therefore, even if a wooden crosspiece 2 is present adjacent to the opening, the wiring protection member 10 can be attached to provide a wiring protection structure that protects the above-mentioned wiring 20.
この配線保護構造では、配線２０を下フランジ１ｃの配線挿通用穴１ｄに挿通させる際は、配線２０が配線挿通用穴１ｄに対して径方向に変位した場合、配線挿通用穴１ｄよりも小径の貫通穴１１の内周に当接することにより、配線２０が配線挿通用穴１ｄの内周に接触して傷付くのを抑制できる。また、貫通穴１１の内周には曲面部１２ａが形成されているため、配線２０が貫通穴１１に接触した際に傷付くのも抑制できる。 In this wiring protection structure, when the wiring 20 is inserted into the wiring insertion hole 1d of the lower flange 1c, if the wiring 20 is displaced radially relative to the wiring insertion hole 1d, the wiring 20 comes into contact with the inner circumference of the through hole 11, which has a smaller diameter than the wiring insertion hole 1d, thereby preventing the wiring 20 from coming into contact with the inner circumference of the wiring insertion hole 1d and being damaged. In addition, since a curved surface portion 12a is formed on the inner circumference of the through hole 11, damage to the wiring 20 when it comes into contact with the through hole 11 can also be prevented.
（２）実施の形態１の配線保護構造では、配線保護部材１０は、本体１０ａが、金属製板により形成されている。また、曲面部１２ａが、貫通穴１１の内周部を、本体１０ａの表裏面の一方である第１の面１０１の方向に折曲させた折曲部としての折返部１２により形成され、かつ、折返部１２の第１の面１０１からの突出代は、配線挿通用穴１ｄの軸方向寸法以下に形成されている。そして、折返部１２を、配線挿通用穴１ｄに挿入し、貫通穴１１を配線挿通用穴１ｄの内側に配置している。 (2) In the wiring protection structure of embodiment 1, the wiring protection member 10 has a main body 10a formed from a metal plate. The curved surface portion 12a is formed by folding back portion 12, which is a folded portion formed by folding the inner periphery of the through hole 11 toward the first surface 101, which is one of the front and back surfaces of the main body 10a, and the protrusion of the folded back portion 12 from the first surface 101 is formed to be equal to or smaller than the axial dimension of the wiring insertion hole 1d. The folded back portion 12 is inserted into the wiring insertion hole 1d, and the through hole 11 is disposed inside the wiring insertion hole 1d.
したがって、折返部１２を配線挿通用穴１ｄに挿入することにより、貫通穴１１および本体１０ａの位置決めを容易に行うことができる。また、配線保護部材１０に外力が作用して貫通穴１１の径方向へ移動しようとした際には、折返部１２が配線挿通用穴１ｄの内周と係合して移動が規制される。 Therefore, by inserting the folded portion 12 into the wire insertion hole 1d, the through hole 11 and the main body 10a can be easily positioned. Furthermore, when an external force acts on the wire protection member 10 and it attempts to move in the radial direction of the through hole 11, the folded portion 12 engages with the inner circumference of the wire insertion hole 1d to restrict the movement.
よって、配線保護部材１０は、第１の面１０１を下フランジ１ｃの上面に重ねるが、その際に、貫通穴１１が配線挿通用穴１ｄに対してずれて取り付けられることを防止できる。そして、これにより、配線保護部材１０の取付位置がずれることを原因とする配線２０の傷付きを防止することができる。また、折返部１２の本体１０ａの第２の面１０２からの突出代は、配線挿通用穴１ｄの軸方向寸法以下に形成されているため、折返部１２が、配線挿通用穴１ｄの開口に接して設けられている木桟２と干渉することなく、配線保護部材１０を下フランジ１ｃに取り付けることができる。 The first surface 101 of the wiring protection member 10 is placed on the upper surface of the lower flange 1c, but the through hole 11 is prevented from being misaligned with respect to the wiring insertion hole 1d when it is attached. This prevents the wiring 20 from being damaged due to the wiring protection member 10 being attached in a misaligned position. In addition, the protrusion of the folded portion 12 from the second surface 102 of the main body 10a is formed to be equal to or smaller than the axial dimension of the wiring insertion hole 1d, so the folded portion 12 does not interfere with the wooden crosspiece 2 that is provided adjacent to the opening of the wiring insertion hole 1d, and the wiring protection member 10 can be attached to the lower flange 1c.
（３）実施の形態１の配線保護構造では、配線保護部材１０は、折返部１２は、貫通穴１１の内周部を外径方向に折り返して形成され、かつ、折返部１２の先端面による外径ｄ２が、配線挿通用穴１ｄの内径と同寸法に形成されている。 (3) In the wiring protection structure of embodiment 1, the wiring protection member 10 has a folded portion 12 formed by folding back the inner periphery of the through hole 11 in the outer diameter direction, and the outer diameter d2 of the tip surface of the folded portion 12 is formed to be the same dimension as the inner diameter of the wiring insertion hole 1d.
したがって、配線保護部材１０の取付時には、折返部１２の先端を配線挿通用穴１ｄの内周に嵌め合わせれば、配線保護部材１０の下フランジ１ｃに対する位置決めができるとともに、位置決め後に配線保護部材１０の位置がずれるのを抑制できる。 Therefore, when installing the wiring protection member 10, the tip of the folded portion 12 can be fitted into the inner circumference of the wiring insertion hole 1d to position the wiring protection member 10 relative to the lower flange 1c, and the position of the wiring protection member 10 can be prevented from shifting after positioning.
（他の実施の形態）
次に、本開示の他の実施の形態について説明する。 なお、他の実施の形態の説明において、他の実施の形態と共通する構成には当該実施の形態と同じ符号を付して説明を省略し、当該実施の形態との相違点のみ説明する。
Other Embodiments
Next, other embodiments of the present disclosure will be described. In the description of the other embodiments, the same reference numerals as in the other embodiments will be used to designate configurations common to the other embodiments, and descriptions thereof will be omitted. Only differences from the other embodiments will be described.
（実施の形態２）
以下に、実施の形態２の配線保護構造に用いる図５に示す配線保護部材２１０について説明する。
この配線保護部材２１０は、本体２１０ａに図３に示すねじ穴１３が形成されている点で、実施の形態１と異なる。したがって、配線保護部材２１０を下フランジ１ｃに固定する際には、固定ねじ２２０を、ねじ穴１３に挿通させ、下フランジ１ｃおよび木桟２に締結して固定させる。
(Embodiment 2)
The wire protection member 210 shown in FIG. 5 and used in the wire protection structure of the second embodiment will be described below.
This wiring protection member 210 differs from the first embodiment in that the main body 210a is formed with the screw holes 13 shown in Fig. 3. Therefore, when fixing the wiring protection member 210 to the lower flange 1c, the fixing screws 220 are inserted through the screw holes 13 and fastened to the lower flange 1c and the wooden crosspiece 2 to fix the wiring protection member 210 to the lower flange 1c.
この実施の形態２では、配線保護部材２１０が、下フランジ１ｃに強固に固定されるため、配線２０を挿通する際に、配線保護部材２１０が、下フランジ１ｃに対して移動するのを、より確実に防止することができる。また、実施の形態１と同様に、上記（１）～（３）の効果を奏する。 In this second embodiment, the wiring protection member 210 is firmly fixed to the lower flange 1c, so that the wiring protection member 210 can be more reliably prevented from moving relative to the lower flange 1c when the wiring 20 is inserted. Also, like the first embodiment, the above effects (1) to (3) are achieved.
（実施の形態３）
実施の形態３の配線保護構造に用いる図６に示す配線保護部材３１０は、実施の形態１で示した折返部１２と異なる形状の折曲部３１２を備える。すなわち、折曲部３１２は、バーリング加工によりフランジ部３１２ａを本体３１０ａの第１の面１０１から立ち上げるよう折曲させることで形成されている。
(Embodiment 3)
6 used in the wiring protection structure of the third embodiment includes a bent portion 312 having a shape different from that of the folded portion 12 shown in the first embodiment. That is, the bent portion 312 is formed by bending the flange portion 312a by burring so as to rise from the first surface 101 of the main body 310a.
この場合、フランジ部３１２ａの高さは、下フランジ１ｃの板厚と同寸法、あるいはそれ以下の寸法とされている。また、折曲部３１２を形成することで、貫通穴３１１の内周に曲面部３１２ｂが形成される。 In this case, the height of the flange portion 312a is the same as or less than the plate thickness of the lower flange 1c. In addition, by forming the bent portion 312, a curved surface portion 312b is formed on the inner periphery of the through hole 311.
（３－１）実施の形態３の配線保護構造では、配線保護部材３１０の折曲部３１２は、貫通穴３１１の内周部を第１の面１０１の側にフランジ部３１２ａを起立させて形成され、かつ、フランジ部３１２ａの外周による外径が、配線挿通用穴１ｄの内径と同寸法に形成されている。したがって、実施の形態３にあっても、上記（３）の効果を得ることができる。
また、配線保護部材３１０は、曲面部３１２ｂを有し、かつ、貫通穴３１１の配置も実施の形態１と同様であるため、実施の形態１と同様に、上記（１）（２）の効果を得ることができる。
(3-1) In the wiring protection structure of the third embodiment, the bent portion 312 of the wiring protection member 310 is formed by raising the flange portion 312a on the inner periphery of the through hole 311 toward the first surface 101, and the outer diameter of the outer periphery of the flange portion 312a is formed to be the same as the inner diameter of the wiring insertion hole 1d. Therefore, even in the third embodiment, the effect of (3) above can be obtained.
Furthermore, since the wiring protection member 310 has the curved portion 312b and the arrangement of the through holes 311 is the same as in the first embodiment, the effects (1) and (2) described above can be obtained in the same manner as in the first embodiment.
（実施の形態４）
実施の形態４の配線保護構造に用いる配線保護部材４１０を、図７に基づいて説明する。この配線保護部材４１０は、樹脂成型により板状に形成された略長方形の本体４１０ａと、本体４１０ａの中央に形成された貫通穴４１１と、を備えるものである。実施の形態４の配線保護部材４１０では、貫通穴４１１の内周に図示のような内径方向に凸の曲面状に加工された曲面部４１２ａが形成されている。
(Embodiment 4)
A wire protection member 410 used in the wire protection structure of the fourth embodiment will be described with reference to Fig. 7. This wire protection member 410 includes a substantially rectangular main body 410a formed into a plate shape by resin molding, and a through hole 411 formed in the center of the main body 410a. In the wire protection member 410 of the fourth embodiment, a curved surface portion 412a that is processed into a curved surface shape that is convex in the inner diameter direction as shown in the figure is formed on the inner periphery of the through hole 411.
この実施の形態４の配線保護構造では、配線保護部材４１０は、実施の形態１と同様に、本体４１０ａを下フランジ１ｃの上面に重ね、貫通穴４１１を配線挿通用穴１ｄの内側に配置し、下フランジ１ｃに固定する。なお、この固定は、実施の形態１と同様に、粘着固定テープ３０により固定してもよいし、実施の形態２と同様に、固定ねじ２２０により固定してもよい。 In the wiring protection structure of this embodiment 4, the wiring protection member 410 is fixed to the lower flange 1c by placing the main body 410a on the upper surface of the lower flange 1c, and arranging the through hole 411 inside the wiring insertion hole 1d, as in embodiment 1. Note that this fixing may be done with adhesive fixing tape 30, as in embodiment 1, or with fixing screws 220, as in embodiment 2.
この実施の形態４の配線保護構造は、配線保護部材４１０の貫通穴４１１を配線挿通用穴１ｄに対して径方向で内側に配置するとともに、本体４１０ａを下フランジ１ｃの上面に当接させた状態で配線保護部材４１０が下フランジ１ｃに固定されている。 In the wiring protection structure of this embodiment 4, the through hole 411 of the wiring protection member 410 is positioned radially inward from the wiring insertion hole 1d, and the wiring protection member 410 is fixed to the lower flange 1c with the main body 410a abutting against the upper surface of the lower flange 1c.
したがって、実施の形態４の配線保護部材４１０および配線保護構造にあっても、上記（１）の効果を得ることができる。 Therefore, the effect of (1) above can be obtained even with the wiring protection member 410 and wiring protection structure of embodiment 4.
以上、図面を参照して、本開示の配線保護構造の実施の形態を詳述してきたが、具体的な構成は、この実施の形態に限らず、本発明の要旨を逸脱しない程度の設計的変更は、本発明に含まれる。 The above describes in detail an embodiment of the wiring protection structure of the present disclosure with reference to the drawings, but the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are included in the present invention.
例えば、実施の形態では、金属材として金属梁を示したが、金属材は、金属板製のものであれば金属梁に限定されるものではない。また、金属梁は、実施の形態で示したコの字断面状のものに限定されない。 For example, in the embodiment, a metal beam is shown as the metal material, but the metal material is not limited to a metal beam as long as it is made of a metal plate. Also, the metal beam is not limited to the U-shaped cross section shown in the embodiment.
また、配線保護部材の金属材への固定は、実施の形態で示したものに限定されるものではなく、接着材など他の固定手段を用いて固定してもよい。 The method of fixing the wiring protection member to the metal material is not limited to that shown in the embodiment, and other fixing means such as adhesive may be used.
また、実施の形態では、本体が金属製のものに折曲部を設けた例を示したが、樹脂製のものにおいて、実施の形態で示した折曲部や折返部と同様の形状のものを成型してもよい。逆に、実施の形態では、本体が樹脂製のものの貫通穴の内周に曲面部を設けた例を示したが、金属製のものの貫通穴の内周に曲面部を形成してもよい。 In addition, in the embodiment, an example was shown in which a bent portion was provided in a metal body, but a resin body may be molded with a shape similar to the bent portion or folded-back portion shown in the embodiment. Conversely, in the embodiment, an example was shown in which a curved portion was provided on the inner periphery of a through hole in a resin body, but a curved portion may be formed on the inner periphery of a through hole in a metal body.
