Description

本発明は、ワイヤー固定具に関し、特に道路の側面に設けられる遮音壁の遮音板の落下を防止するために設けられるワイヤーを固定するために好適なワイヤー固定具に関するものである。 The present invention relates to a wire fixture, and more particularly to a wire fixture suitable for fixing a wire provided to prevent a sound insulation plate of a sound insulation wall provided on a side surface of a road from falling.

一般に、複数の構成要素からなる構造物は、その構成要素どうしをワイヤーで連結して一体とされる場合が多い。例えば、自動車交通騒音の減音対策として多数設置されている、相対するＨ型支柱の溝に遮音板を嵌め込んで積層する型式の遮音壁においては、積層された遮音板どうしがワイヤーで連結され一体の遮音壁とされている。この場合、遮音板どうしを連結することにより、遮音板の落下防止を図ることが行なわれている。
しかし、上記遮音壁のように複数の構造物どうしをワイヤーで連結する場合には、そのワイヤーを固定しなければならない。そして、ワイヤーを安定して固定するためには、固定手段を設けるなど特別な措置を施す必要のある場合が多く、コスト面や作業性に問題があった。 In general, a structure composed of a plurality of constituent elements is often integrated by connecting the constituent elements with a wire. For example, in a type of sound insulation wall that is installed as a measure against noise reduction of automobile traffic noise and is laminated by inserting sound insulation plates into the grooves of opposing H-type struts, the laminated sound insulation plates are connected by wires and integrated. It is considered as a sound insulation wall. In this case, the sound insulation plates are prevented from falling by connecting the sound insulation plates.
However, when a plurality of structures are connected by a wire such as the sound insulation wall, the wire must be fixed. And in order to fix a wire stably, it is necessary to take special measures, such as providing a fixing means, and there existed a problem in cost and workability | operativity.

作業性を改善したワイヤー固定具として、先端に拡径部を備えたワイヤーを、該拡径部の最大径よりも大きい径を有するワイヤー挿通孔を備えた板状の被固定部に固定する固定具として、被固定部を厚み方向に挟持できるように折曲された板材からなり、拡径部の最大径よりも大きい径を有する透孔と、透孔に連続し拡径部の最小径よりも狭くワイヤーの径よりも広い幅のスリットを備えたワイヤー固定具が知られている。（特許文献１） As a wire fixing tool with improved workability, fixing a wire having a diameter-enlarged portion at the tip to a plate-like fixed portion having a wire insertion hole having a diameter larger than the maximum diameter of the diameter-enlarged portion As a tool, it is composed of a plate material bent so that the fixed part can be sandwiched in the thickness direction, and has a through hole having a diameter larger than the maximum diameter of the enlarged diameter part, and a minimum diameter of the enlarged diameter part continuous with the through hole. A wire fixture having a slit that is narrower and wider than the diameter of the wire is known. (Patent Document 1)

特開２００２−２２７１４５号公報JP 2002-227145 A

上記特許文献１に示す固定具によれば、ワイヤー固定具が被固定部に固定された状態において、拡径部の基端がスリットの周縁部に係合して、ワイヤーが被固定部のワイヤー挿通孔からの脱落することが防止され、ワイヤーを被固定部に固定することができる。その上、板材の両片部の間隔が被固定部材の厚さよりも狭くなる部分を設け、固定具が固定された状態において、板材の両片部が被固定部に強く圧着され、固定強度を強化することを開示している。
しかし、組付け作業時、板材の透孔と被固定部のワイヤー挿通孔とを一致させて、ワイヤーを挿通させた後、ワイヤー固定具のスリットと被固定部のワイヤー挿通孔とを一致させるためにワイヤー固定具を被固定部に押し込んだ際に、素直に挿通されずにお互いの位置がずれて、取り付け作業に時間がかかることがある。
また、取り付け後でも振動等により、スリットとワイヤー挿通孔との位置がずれて、ガタが生じて振動音を発したり、ワイヤーを損傷したりしたりすることがあり、耐久性に劣っていた。極端な場合にはワイヤー固定具が被固定部から外れる可能性もあった。 According to the fixture shown in Patent Document 1, in the state where the wire fixture is fixed to the fixed portion, the proximal end of the enlarged diameter portion engages with the peripheral portion of the slit, and the wire is the wire of the fixed portion. It is prevented from falling off from the insertion hole, and the wire can be fixed to the fixed portion. In addition, a portion where the distance between the two pieces of the plate material is narrower than the thickness of the member to be fixed is provided, and in the state where the fixture is fixed, the two pieces of the plate material are strongly pressed against the fixed portion, and the fixing strength is increased. It is disclosed to strengthen.
However, during assembly work, after aligning the through hole of the plate and the wire insertion hole of the fixed part and inserting the wire, the slit of the wire fixture and the wire insertion hole of the fixed part are aligned When the wire fixing tool is pushed into the fixed portion, the positions may be shifted without being straightly inserted, and it may take time for the mounting work.
In addition, even after attachment, the position of the slit and the wire insertion hole may be shifted due to vibration or the like, resulting in play and vibration noise or damage to the wire, which is inferior in durability. In extreme cases, there is a possibility that the wire fixing tool may come off from the fixed part.

以下、本発明の実施形態を図面に基づいて説明する。
（実施形態１）
本発明にかかるワイヤー固定具の実施形態１を図１〜図５により説明する。図１はワイヤ−固定具が遮音壁に使用されている状態の概観を示す斜視図である。図２はワイヤー固定具の斜視図である。図３はワイヤー固定具が固定される被固定部材の正面図である。図４はワイヤー固定具を挿入し、ワイヤーを挿通した状態を示す正面図である。図５はワイヤー固定具が更に挿入され、固定された状態を示す正面図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
Embodiment 1 of a wire fixture according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing an overview of a state in which a wire-fixing tool is used for a sound insulation wall. FIG. 2 is a perspective view of the wire fixture. FIG. 3 is a front view of a fixed member to which the wire fixing tool is fixed. FIG. 4 is a front view showing a state in which the wire fixture is inserted and the wire is inserted. FIG. 5 is a front view showing a state in which the wire fixing tool is further inserted and fixed.

この実施形態１ではワイヤー定具１は、図１に示すように、遮音壁１０において遮音板４の落下を防止するワイヤー２を固定するために使用されている。遮音壁１０は、相対するＨ型支柱５の溝６に遮音板４が嵌め込まれ積層されて構成されている。積層された遮音板４どうしは、遮音板４の側面に設けられたワイヤー挿通部７に挿通されたワイヤー２を介して一体に連結されている。
また、遮音板４の側面は凹んでおり、溝６にはめ込まれた際に、この側面とＨ型支柱５のウェブ３’との間に形成される空間４１に、ワイヤー挿通部７及びワイヤー２が収容されるようになっている。 In the first embodiment, as shown in FIG. 1, the wire fixing tool 1 is used to fix a wire 2 that prevents the sound insulating plate 4 from falling in a sound insulating wall 10. The sound insulation wall 10 is constituted by a sound insulation plate 4 fitted and laminated in a groove 6 of an opposing H-shaped support column 5. The laminated sound insulation plates 4 are integrally connected via a wire 2 inserted through a wire insertion portion 7 provided on a side surface of the sound insulation plate 4.
Further, the side surface of the sound insulating plate 4 is recessed, and when inserted into the groove 6, the wire insertion portion 7 and the wire 2 are formed in a space 41 formed between the side surface and the web 3 ′ of the H-shaped support column 5. Are to be accommodated.

なお、図１において、遮音板４のウェブ３’を挟んだ反対側の溝には、別の遮音板が嵌め込まれ、ワイヤー２’で連結されているが、固定具１の構造を明確にするため、その図示は省略されている。また、図２〜図５においては、紙面手前側に嵌め込まれる遮音板の図示が省略されている。 In FIG. 1, another sound insulation plate is fitted in the groove on the opposite side across the web 3 ′ of the sound insulation plate 4 and connected by a wire 2 ′, but the structure of the fixture 1 is clarified. Therefore, the illustration is omitted. Moreover, in FIGS. 2-5, illustration of the sound insulation board fitted by the paper surface near side is abbreviate | omitted.

ワイヤー２の先端に拡径部２１が設けられている。図３に示すように、Ｈ型支柱５のウェブ３’（本発明の被固定部３に該当）上端近傍には、拡径部２１の最大径よりも大きい径を有するワイヤー挿通孔３１が設けられ、ワイヤー２の先端が挿通できるようになっている。 An enlarged diameter portion 21 is provided at the tip of the wire 2. As shown in FIG. 3, a wire insertion hole 31 having a diameter larger than the maximum diameter of the enlarged diameter portion 21 is provided in the vicinity of the upper end of the web 3 ′ (corresponding to the fixed portion 3 of the present invention) of the H-type support column 5. The tip of the wire 2 can be inserted.

図２に示すように、ワイヤー固定具１は、ウェブ３’を厚み方向に挟持できるように折曲された断面略コ字状の板材１３からなる。この板材１３は、対面する両片部１４ａ、１４ｂと、これらの端部を接続する接続片部１５からなる。両片部１４ａ、１４ｂには、拡径部２１の最大径よりも大きい径を有する透孔１１と、透孔１１に連続するスリット１２が形成されている。このスリット１２の幅は、拡径部２１の最小径よりも狭くワイヤー２の径よりも広くなっている。板材１３の両片部１４ａ、１４ｂの間隔は、接続片部１５側が広く、先端側になるにしたがってその間隔が徐々に狭くなっており、この間隔を無理やり広げた際には元に戻ろうとする弾性復元力が作用するようになっている。
板材の片部１４ａの先端は他方の片部１４ｂの先端より短く形成され、且つ片部１４ａの先端は外側に拡大された拡大部１６を有する。この構造によって、ワイヤー固定具１を被固定部材３に挿入する際の作業を容易にしている。また、片部１４ａと片部１４ｂとの先端間隔を被固定部材３の厚さよりも僅かに狭くすることで、この先端部で被固定部材３を挟み、弾性復元力が作用することでガタつくことなく把持できる。また、先端の間隔を弾性変形させて拡げてワイヤー固定具１を被固定部材３に挿入することで被固定部材３の板厚の少し異なるものでも装着できる。 As shown in FIG. 2, the wire fixture 1 is composed of a plate material 13 having a substantially U-shaped cross section that is bent so that the web 3 ′ can be sandwiched in the thickness direction. The plate member 13 includes both pieces 14a and 14b facing each other and a connection piece 15 connecting these ends. Both pieces 14 a and 14 b are formed with a through hole 11 having a diameter larger than the maximum diameter of the enlarged diameter portion 21 and a slit 12 continuing to the through hole 11. The width of the slit 12 is narrower than the minimum diameter of the enlarged diameter portion 21 and wider than the diameter of the wire 2. The interval between the two pieces 14a and 14b of the plate 13 is wider on the connecting piece 15 side and gradually decreases toward the tip side. When the interval is forcibly widened, the interval is to be restored. An elastic restoring force is applied.
The front end of the piece portion 14a of the plate material is formed shorter than the front end of the other piece portion 14b, and the front end of the piece portion 14a has an enlarged portion 16 that is expanded outward. This structure facilitates the operation when inserting the wire fixture 1 into the member 3 to be fixed. Further, by making the tip interval between the piece portion 14a and the piece portion 14b slightly narrower than the thickness of the member 3 to be fixed, the member 3 to be fixed is sandwiched by this tip portion, and the elastic restoring force acts to rattle. It can be gripped without Further, by inserting the wire fixture 1 into the member 3 to be fixed by elastically deforming the distance between the tips, it is possible to attach even a slightly different plate thickness of the member 3 to be fixed.

板材１３の両片部１４ａ、１４ｂに形成したスリット１２の周囲には、互いに内方に突出する略椀形状のボス部１７が一体に形成されている。ワイヤー固定具１を被固定部材３に挿入して、透孔１１とワイヤー挿通孔３１とが一致した状態でワイヤーを挿通した後、更にワイヤー固定具１を奥に挿入し、スリット１２とワイヤー挿通孔３１とが一致した状態にする場合に、ボス部１７がワイヤー挿通孔３１に遊嵌されるので容易に位置決めでき、作業性に優れる。また、ボス部１７が被固定部材３のワイヤー挿通孔３１に遊嵌されることにより、ワイヤー固定具１の位置ズレが防止される。また、上記ボス部１７の直径がスリット１２の長さにほぼ等しい状態で形成することで、スリット１２が円弧状に形成され、強度アップされる。 Around the slits 12 formed in the two pieces 14a and 14b of the plate member 13, a substantially bowl-shaped boss portion 17 projecting inward is integrally formed. After inserting the wire fixture 1 into the member 3 to be fixed and inserting the wire in a state where the through hole 11 and the wire insertion hole 31 coincide with each other, the wire fixture 1 is further inserted into the back, and the slit 12 and the wire are inserted. When the hole 31 is in a state of being coincident, the boss portion 17 is loosely fitted into the wire insertion hole 31 so that it can be easily positioned and is excellent in workability. Further, the boss portion 17 is loosely fitted into the wire insertion hole 31 of the fixed member 3, thereby preventing the wire fixing tool 1 from being displaced. Further, by forming the boss portion 17 in a state where the diameter of the boss portion 17 is substantially equal to the length of the slit 12, the slit 12 is formed in an arc shape and the strength is increased.

次に、実施形態１のワイヤー固定具１を使用した、本発明にかかるワイヤーの固定方法の具体例について説明する。
まず、第一に、ワイヤー固定具１を被固定部材３であるウェブ３’に挿入して、透孔１１とワイヤー挿通孔３１とが一致した状態で、ワイヤー２の拡径部２１を透孔１１及びワイヤー挿通孔３１に挿通させ、ワイヤー２の一部を透孔１１及びワイヤー挿通孔３１に通して、図４に示す状態とする。そして次に、ワイヤー固定具１を奥まで挿入し、ボス１７がワイヤー挿通孔３１に嵌り込ませる。この位置で、スリット１２とワイヤー挿通孔３１とが重なる位置となり、図５に示す固定状態として固定作業が終了する。この位置で、ワイヤー固定具１は固定されるので、スリット１２とワイヤー挿通孔３１との位置がずれることがない。したがって、ワイヤー２が外れることが確実に防止でき、遮音板４の落下を効果的に防止できる。その上、ボス１７を設けたことによって、スリット１２とワイヤー挿通孔３１との位置合わせが容易であり、作業性に優れる。また、ボス１７はスリット１２の補強になっている。
なお、ボス１７が椀形状に形成されているので、スリット１２とワイヤー挿通孔３１との位置合わせが極めて容易である。特に、ボス１７の椀形状の直径（外径）を、ほぼワイヤー挿通孔３１の直径と同じとすることで、スリット１２とワイヤー挿通孔３１との位置がずれることを確実に防止できる。なお、ボス１７の椀形状の直径（外径）が、ワイヤー挿通孔３１の直径よりも少し大きくても、ボス１７の椀形状の一部がワイヤー挿通孔３１に嵌るので、位置ズレを防止できる。 Next, the specific example of the fixing method of the wire concerning this invention using the wire fixing tool 1 of Embodiment 1 is demonstrated.
First, first, the wire fixture 1 is inserted into the web 3 ′ which is the member to be fixed 3, and the diameter-expanded portion 21 of the wire 2 is penetrated in a state where the through-hole 11 and the wire insertion hole 31 coincide. 11 and the wire insertion hole 31 and a part of the wire 2 is passed through the through hole 11 and the wire insertion hole 31 to obtain the state shown in FIG. Next, the wire fixture 1 is inserted to the back, and the boss 17 is fitted into the wire insertion hole 31. At this position, the slit 12 and the wire insertion hole 31 overlap with each other, and the fixing operation is completed as the fixing state shown in FIG. Since the wire fixing tool 1 is fixed at this position, the positions of the slit 12 and the wire insertion hole 31 do not shift. Therefore, the wire 2 can be reliably prevented from coming off, and the sound insulating plate 4 can be effectively prevented from falling. In addition, since the boss 17 is provided, the alignment between the slit 12 and the wire insertion hole 31 is easy, and the workability is excellent. Further, the boss 17 is a reinforcement of the slit 12.
In addition, since the boss | hub 17 is formed in the hook shape, position alignment with the slit 12 and the wire penetration hole 31 is very easy. In particular, it is possible to reliably prevent the positions of the slit 12 and the wire insertion hole 31 from shifting by making the diameter (outer diameter) of the boss 17 substantially the same as the diameter of the wire insertion hole 31. Even if the diameter (outer diameter) of the boss 17 is slightly larger than the diameter of the wire insertion hole 31, a part of the ridge shape of the boss 17 fits into the wire insertion hole 31, thereby preventing misalignment. .

なお、図１に示すように、ウェブ３’の両側にワイヤー２、２’がそれぞれ配設される場合には、透孔１１及びワイヤー挿通孔３１に、ワイヤー２（又はワイヤー２’）の一部を通した状態において、反対側から同様にもう一方のワイヤー２’（又はワイヤー２）を挿通させればよい。そして、両ワイヤー２、２’を透孔１１及びワイヤー挿通孔３１に通して交差させた状態でワイヤー固定具１を摺動させることにより、両ワイヤー２、２’を同時に固定することができる。 As shown in FIG. 1, when the wires 2 and 2 ′ are respectively disposed on both sides of the web 3 ′, one of the wires 2 (or the wires 2 ′) is inserted into the through holes 11 and the wire insertion holes 31. What is necessary is just to let another wire 2 '(or wire 2) penetrate similarly from the opposite side in the state which passed the part. The wires 2 and 2 ′ can be simultaneously fixed by sliding the wire fixture 1 in a state where the wires 2 and 2 ′ are passed through the through-hole 11 and the wire insertion hole 31 and crossed.

板材１３の片部１４ａは片部１４ｂより短く、且つ片部１４ａの先端には拡大部１６が設けられているので、被固定部材３であるウェブ３’にワイヤー固定部１を挿入する際に、その作業を極めて容易に行うことができる。
また、板材１３の片部１４ａ、１４ｂは、接続片部１５から先端に向けて徐々に間隔が狭くなるようになっており、かつ先端側の間隔はウェブ３’の厚みよりも狭くなっているので、ワイヤー固定具１を上方から力を加えながら下方に摺動させることで、弾性変形させて間隔を拡大させながら挿入する。そうすると、ワイヤー固定具１が固定された状態において、板材の両片部１４ａ、１４ｂがウェブ３’に強く圧着できるので、固定強度を高めることができる。 Since the piece portion 14a of the plate 13 is shorter than the piece portion 14b and the enlarged portion 16 is provided at the tip of the piece portion 14a, when the wire fixing portion 1 is inserted into the web 3 ′ that is the member 3 to be fixed. The operation can be performed very easily.
Further, the pieces 14 a and 14 b of the plate member 13 are gradually spaced from the connecting piece 15 toward the tip, and the tip side is narrower than the thickness of the web 3 ′. Therefore, the wire fixture 1 is inserted while increasing the interval by being elastically deformed by sliding downward while applying a force from above. If it does so, in the state to which the wire fixing tool 1 was fixed, since both the piece parts 14a and 14b of a board | plate material can be crimped | bonded strongly to web 3 ', fixing strength can be raised.

本発明の実施形態１では、ボス１７を椀形状に形成したので、固定部材３のワイヤー挿入孔３１に位置決め固定することが容易であり、ワイヤー挿入孔３１の孔径よりもボス１７の椀形状の外径が少し大きくても、椀形状の途中の面で位置決めでき、ワイヤー挿入孔３１の孔径よりもボス１７の椀形状の外径が少し小さい場合には、少しガタがあるが、スリット１２とワイヤー挿入孔３１との位置がずれることがないので、容易に位置決めできる。
なお、ボス１７の形状は椀形状に限らず、 In Embodiment 1 of the present invention, since the boss 17 is formed in a hook shape, it is easy to position and fix the wire insertion hole 31 of the fixing member 3, and the boss 17 has a hook shape larger than the hole diameter of the wire insertion hole 31. If the outer diameter of the boss 17 is slightly smaller than the diameter of the wire insertion hole 31 even if the outer diameter is a little larger, it can be positioned on the middle surface of the hook shape. Since the position with respect to the wire insertion hole 31 does not shift, it can be easily positioned.
In addition, the shape of the boss 17 is not limited to the hook shape,

スリット１２を透孔１１の側方に設け、ワイヤー固定具１を側方に摺動させて固定するようにしてもよい。そうすると、ワイヤー２に鉛直方向の力が働いてワイヤー２の脱落を防止できる。 The slit 12 may be provided on the side of the through hole 11, and the wire fixture 1 may be slid to the side to be fixed. If it does so, the force of a perpendicular direction will act on the wire 2 and it can prevent drop-out of the wire 2.

なお、前記実施形態１に示すように、相対するＨ型支柱５の溝６に遮音板４を嵌め込んで積層する型式の遮音壁１０における、Ｈ型支柱５のウェブ３’を被固定部３とすると、ワイヤー２の固定手段を備えていないＨ型支柱５にもワイヤー挿通孔３１を設けるだけで適用することができる。また、既設の遮音壁に適用する場合にも、固定手段を備えた新しいＨ型支柱と交換する必要がなく、コストを低減できるという作用効果を得ることができる。 As shown in the first embodiment, the web 3 ′ of the H-shaped column 5 is connected to the fixed portion 3 in the sound-insulating wall 10 of the type in which the sound-insulating plate 4 is fitted into the groove 6 of the opposite H-shaped column 5 and stacked. Then, it can be applied to the H-shaped support column 5 that is not provided with the fixing means for the wire 2 simply by providing the wire insertion hole 31. In addition, when applied to an existing sound insulation wall, it is not necessary to replace with a new H-type support provided with a fixing means, and an effect that the cost can be reduced can be obtained.

本発明にかかるワイヤー固定具を使用する被固定部はＨ型支柱のウェブに限定されず、その他の板材であってもよい。 The to-be-fixed part which uses the wire fixing tool concerning this invention is not limited to the web of an H-type support | pillar, Other board | plate materials may be sufficient.
