Description

本発明は、例えば鉄道や高速道路に利用される吸音または防音のためのパネルの固定具及び同パネルの設置方法に関する。さらに詳しくは、断面コ字型部分を対向させた支柱間に挿入される吸音または防音のためのパネルを固定すべく、前記コ字型フランジまたはこれに装着された補助部材と前記パネルとの間に装着され、屈曲されたばね部を有し帯状部材を屈曲形成したばね部材と、雌ねじ部を有する雌ねじ部材及びこれに螺合してばね部に当接するボルトを有し、前記ボルトの締め付けにより前記ばね部の弾性力で前記パネルを前記コ字型部分に圧接させて固定するパネルの固定具及び同パネルの設置方法に関する。 TECHNICAL FIELD The present invention relates to a fastener for sound absorbing or soundproofing panels used, for example, on railroads and highways, and a method for installing the same panels. More specifically, between the U-shaped flange or an auxiliary member attached thereto and the panel for fixing the panel for sound absorption or sound insulation inserted between the columns with the U-shaped cross-sectional portions facing each other a spring member having a bent spring portion and formed by bending a belt-shaped member; a female thread member having a female thread portion; The present invention relates to a panel fixture for pressing and fixing the panel to the U-shaped portion by the elastic force of a spring portion, and a method for installing the panel.

パネルの固定具としては、例えば、次の特許文献１に記載の如きものが知られている。同文献によれば、ばね部に相当する部分を有する支持力伝達部材１をフランジに取り付け、同支持力伝達部材１の入力部１３とナット３との間でボルトを突き出して、フランジとパネルの間で突っ張らせ、パネルをフランジに圧接し固定している。 As a fixture for the panel, for example, the one described in Patent Document 1 below is known. According to the document, a bearing force transmission member 1 having a portion corresponding to a spring portion is attached to a flange, and a bolt is protruded between an input portion 13 of the bearing force transmission member 1 and a nut 3 to connect the flange and the panel. The panel is pressed against the flange and fixed.

ところで、同固定具では、緩み止め座金４を用い、ボルトの頭部がこの座金に接触するまで締め込むことを前提としている。したがって、パネルの厚さやフランジ間隔が異なれば、長さの異なるボルトを準備せねばならず煩雑である。ところで、想定ではあるが、仮に長めのボルトを用いて任意位置でボルトの螺合を止めるとなると、支持力伝達部材１のばね力を一定に働かせるためにトルク管理となる。しかし、ナット３とボルトと支持力伝達部材１との相対位置は、同文献によれば、ストッパ６を介してすべてが固定されており、入力部１３とナット３との距離が変わると、ボルト先端と入力部１３のボルト長手直交方向に対する位置も変更される。したがって、これらの当接が正常なばね力を確保する程度に確保できないことや、上記トルク管理に支障をきたす場合も懸念され、この場合はパネルの確実な固定を管理するのが困難となる。 By the way, in this fixture, it is premised that the locking washer 4 is used and the bolt head is tightened until it contacts this washer. Therefore, if the thickness of the panel and the distance between the flanges are different, bolts of different lengths must be prepared, which is complicated. By the way, although it is assumed, if a long bolt is used and screwing of the bolt is stopped at an arbitrary position, the torque is controlled in order to keep the spring force of the supporting force transmission member 1 constant. However, according to the document, the relative positions of the nut 3, the bolt, and the supporting force transmission member 1 are all fixed via the stopper 6, and when the distance between the input portion 13 and the nut 3 changes, the bolt The positions of the tip and the input portion 13 with respect to the longitudinal direction of the bolt are also changed. Therefore, there is a concern that these abutments cannot be ensured to the extent that a normal spring force is ensured, or that the torque management is hindered, and in this case, it becomes difficult to manage the reliable fixing of the panel.

かかる従来の実情に鑑みて、本発明は、ボルトの螺合ストロークが変わっても、トルク管理によりばね部の押し付け力を適正に保つことの可能なパネルの固定具及び同パネルの設置方法を提供することを目的とする。 In view of such conventional circumstances, the present invention provides a panel fixture and a panel installation method that can maintain the pressing force of the spring portion appropriately by torque management even if the screwing stroke of the bolt changes. intended to

上記目的を達成するため、本発明に係るパネルの固定具及び同パネルの設置方法の特徴は、断面コ字型部分を対向させた支柱間に挿入される吸音または防音のためのパネルを固定すべく、前記コ字型フランジまたはこれに装着された補助部材と前記パネルとの間に装着され、屈曲されたばね部を有し帯状部材を屈曲形成したばね部材と、雌ねじ部を有する雌ねじ部材及びこれに螺合してばね部に当接するボルトを有し、前記ボルトの締め付けにより前記ばね部の弾性力で前記パネルを前記コ字型部分に圧接させて固定する構成において、前記ボルトは先端に尖り部を有し、前記ばね部に形成した係止部に前記尖り部を挿入し、前記フランジまたは前記補助部材に形成された貫通孔の前記ばね部側に前記雌ねじ部をねじ軸心との直交方向にスライド自在な状態で位置させる雌ねじ部材を設け、前記雌ねじ部材は雌ねじ部を有する緩み止めナットを有し、前記雌ねじ部との螺合により前記ボルトの尖り部を前記ばね部側に突き出して前記弾性力を調整可能であり、前記ばね部材は、前記フランジまたは前記補助部材に保持する保持部及び前記ばね部とこの保持部とを連結する連結部とを有しこの保持部と連結部とを介して前記ばね部を片持ち状に支持するものであり、前記雌ねじ部材は、前記板状部を有し前記保持部に係合可能なクリップ部を備え、前記緩み止めナットを受けさらにこのナットよりも広い面積で前記ばね部材に接触する板状部を備えていることにある。 In order to achieve the above object, the panel fixture and the method for installing the panel according to the present invention are characterized by fixing a panel for sound absorption or sound insulation inserted between supports with U-shaped cross-sectional portions facing each other. a spring member having a bent spring portion and formed by bending a band-shaped member having a bent spring portion, a female thread member having a female thread portion, and the same and a bolt that contacts the spring portion, and the panel is fixed by pressing against the U-shaped portion by the elastic force of the spring portion when the bolt is tightened, wherein the bolt has a sharp tip. The pointed portion is inserted into the engaging portion formed in the spring portion, and the female thread portion is inserted into the spring portion side of the through hole formed in the flange or the auxiliary member at right angles to the screw axis. A female threaded member is provided so as to be slidable in any direction, the female threaded member has a locking nut having a female threaded portion, and is screwed with the female threaded portion so that the pointed portion of the bolt protrudes toward the spring portion. The elastic force can be adjusted, and the spring member has a holding portion that is held by the flange or the auxiliary member and a connecting portion that connects the spring portion and the holding portion. The female screw member includes a clip portion having the plate-like portion and capable of being engaged with the holding portion, and receives the locking nut.

同構成によれば、ボルトは先端に尖り部を有し、ばね部に形成した係止部に尖り部を挿入してあるので、ばね部に対してボルト先端は確実に係合し、締め付けの変位を伝達できる。しかも、雌ねじ部をねじ軸心との直交方向にスライド自在な状態で位置させる雌ねじ部材を設けてあるので、前記係止部の変位に伴って雌ねじ部もボルトとともにスライドし、雌ねじ部に同直交方向に対する不要なストレスが発生することを防止する。その結果、ボルトの締め付けトルクは前記ばね部より生じる反力を適正に反映し、パネルを適正な圧力でフランジ等に押し付けることができる。しかも、その状態は、前記緩み止めナットで維持される。 According to this configuration, the bolt has a pointed portion at its tip, and since the pointed portion is inserted into the locking portion formed in the spring portion, the tip of the bolt is securely engaged with the spring portion, thereby ensuring tightening. Displacement can be transmitted. Moreover, since the female threaded member is provided so as to allow the female threaded portion to be slidably positioned in the direction perpendicular to the axis of the screw, the female threaded portion slides along with the bolt as the engaging portion is displaced, and is perpendicular to the female threaded portion. To prevent unnecessary directional stress from occurring. As a result, the tightening torque of the bolt appropriately reflects the reaction force generated by the spring portion, and the panel can be pressed against the flange or the like with an appropriate pressure. Moreover, this state is maintained by the locking nut.

また、前記ばね部材は、前記フランジまたは前記補助部材に保持する保持部及び前記ばね部とこの保持部とを連結する連結部とを有しこの保持部と連結部とを介して前記ばね部を片持ち状に支持するものである。 Further, the spring member has a holding portion held by the flange or the auxiliary member and a connecting portion for connecting the spring portion and the holding portion, and the spring portion is held via the holding portion and the connecting portion. It is supported in a cantilever manner.

また、前記雌ねじ部材は、前記板状部を有し前記保持部に係合可能なクリップ部を備え、前記緩み止めナットを受けさらにこのナットよりも広い面積で前記ばね部材に接触する板状部を備えている。 Further, the female screw member has the plate-like portion and a clip portion that can be engaged with the holding portion. It has

前記ばね部は、前記係止部が形成される平坦部と、前記パネルに屈曲させた角で接当する接当部と、これら平坦部および接当部をつなぐ屈曲部とを備えるとよい。 The spring portion preferably includes a flat portion on which the locking portion is formed, a contact portion that contacts the panel at a bent corner, and a bent portion that connects the flat portion and the contact portion.

また、前記貫通孔を設けた前記補助部材をさらに有してもよい。そして、前記フランジに仮止めされる他のクリップと前記他のクリップを固定する他のナットよりなる他の雌ねじ部材をさらに備え、前記補助部材は、固定ボルトを貫通させる他の貫通孔を前記貫通孔とは別に有し、前記フランジは、前記固定ボルトを貫通させる他の貫通孔を有し、前記固定ボルトを前記他のナットに螺合させて前記補助部材を前記フランジに固定しているとよい。 Moreover, you may further have the said auxiliary member which provided the said through-hole. and another female screw member made of another clip temporarily fixed to the flange and another nut for fixing the other clip, and the auxiliary member passes through the other through hole through which the fixing bolt passes. The flange has another through hole through which the fixing bolt passes, and the fixing bolt is screwed into the other nut to fix the auxiliary member to the flange. good.

一方、パネルの固定具を用いたパネルの設置方法の特徴は、前記保持部で前記フランジまたはこのフランジに固定した前記補助部材に前記ばね部材を保持させると共にこの保持部に前記クリップ部で前記雌ねじ部材を保持させ、前記貫通孔を貫通させて前記雌ねじ部に前記ボルトを螺合させて締め付けることにより前記尖り部を前記係止部に挿入させて前記ばね部を前記パネルに押し付け、所定のトルクに達するまで前記ボルトを締め付けることにある。

次に、適宜添付図面を参照しながら、本発明をさらに詳しく説明する。
本発明に係るパネルの固定具１は、図１～６に示すように、ばね部材２０、雌ねじ部材３０、ボルト４０及び必要に応じて補助部材５０を備えている。また、図１，２の例では、パネル２００を固定する支柱１００は、例えばｚ方向が鉛直方向であり、ウエブ１０２の両端にフランジ１０１，１０１を一対有し、これらで断面コ字型部分を形成する。また、支柱１００は、一対がパネル２００の幅方向より少し大きな隔たりでウエブ１０２が対向し、その結果断面コ字状部分が対向するように配置されている。この対向させた支柱１００間にパネル２００は挿入され、設置される。パネル２００は、吸音または防音のためのパネルであり、図示省略するが、音源側は多数の孔やスリットが形成され、内部には吸音材が収納されて反対側は封止された板材であることが多い。このパネル２００は線路や道路等を仕切るものであり、ばね部材２０の強靭で確実な圧接により設置固定される必要があり、本発明はその達成のためになされたものである。 Next, the present invention will be described in more detail with reference to the accompanying drawings as appropriate.
A panel fixture 1 according to the present invention comprises a spring member 20, a female screw member 30, a bolt 40 and, if necessary, an auxiliary member 50, as shown in FIGS. In the example of FIGS. 1 and 2, the strut 100 for fixing the panel 200 has, for example, a vertical direction in the z direction, and has a pair of flanges 101, 101 at both ends of the web 102, which form a U-shaped cross section. Form. In addition, the support columns 100 are arranged so that the webs 102 of the pair face each other with a gap slightly larger than the width direction of the panel 200, and as a result, the U-shaped cross-sectional portions face each other. The panel 200 is inserted and installed between the columns 100 facing each other. The panel 200 is a panel for sound absorption or sound insulation, and although not shown, it is a plate material in which a large number of holes and slits are formed on the sound source side, a sound absorbing material is housed inside, and the opposite side is sealed. There are many things. This panel 200 partitions railroad tracks, roads, etc., and must be installed and fixed by strong and reliable pressure contact of the spring member 20, and the present invention has been made to achieve this.

本実施形態では、フランジ１０１とパネル２００の表面とのクリアランスが、ばね部材２０に比較して小さく、したがって、補助部材５０を含むパネルの固定具１となっている。この補助部材は、板状の補助部材本体５１に形成した２つの貫通孔５１ａ，５１ａ及びフランジ１０１に形成した二つの貫通孔１０１ａ，１０１ａにそれぞれ固定ボルト５２を貫通させ、緩み止めナット５３で締め付けることによりフランジ１０１に固定してある。 In this embodiment, the clearance between the flange 101 and the surface of the panel 200 is smaller than that of the spring member 20 , so that the panel fixture 1 including the auxiliary member 50 is provided. This auxiliary member has two through holes 51a, 51a formed in a plate-like auxiliary member main body 51 and two through holes 101a, 101a formed in a flange 101, respectively. It is thus fixed to the flange 101 .

ばね部材２０は、実質的に弾性変形でパネル２００を固定するばね部２１及び補助部材本体５１またはフランジに保持させる保持部２３と、これらを連結する連結部２２を備えている。ばね部２１は、パネル２００に角で接当する接当部２１ａ、及び、貫通孔としての係止部２１ｃを備えた平坦部２１ｂと、これらをつなぐ屈曲部２１ｄとを有している。一方、ボルト４０は、スパナ等で締め付け操作を行う頭部４１、中間のねじ部４２、及び、先端の円錐状の尖り部４３よりなり、尖り部４３は、貫通孔としての係止部に回転自在に嵌合している。 The spring member 20 includes a spring portion 21 that fixes the panel 200 substantially by elastic deformation, a holding portion 23 that is held by the auxiliary member main body 51 or the flange, and a connecting portion 22 that connects them. The spring portion 21 has a contact portion 21a that contacts the panel 200 at its corner, a flat portion 21b that has a locking portion 21c as a through hole, and a bent portion 21d that connects the flat portion 21b. On the other hand, the bolt 40 consists of a head 41 that is tightened with a wrench or the like, a threaded portion 42 in the middle, and a conical pointed portion 43 at the tip. Fits freely.

保持部２３は側面視コ字状であり、下側部分に雌ねじ部材３０が固定された状態で、フランジに固定した補助部材本体５１に、保持部の締め付けの弾性変形をもって仮止めされる。雌ねじ部材３０は、雌ねじ部３１ａ及びゆるみ止め部３１ｂを有する緩み止めナット３１をクリップ３２に溶接等で固定してなる。クリップ３２は、先の保持部への接触の際の表面積を増大させてスライド自在にするための板状部３２ａ、折り返し部３２ｂ、誘導部３２ｃを有する裏板状部３２ｅを備え、これらの間に保持部３２ｆを形成してなる。 The holding part 23 is U-shaped in side view, and is temporarily fixed to the auxiliary member main body 51 fixed to the flange by elastic deformation due to tightening of the holding part, with the female screw member 30 fixed to the lower part. The female thread member 30 is formed by fixing a locking nut 31 having a female thread portion 31a and a locking portion 31b to a clip 32 by welding or the like. The clip 32 has a plate-like portion 32a, a folded portion 32b, and a back plate-like portion 32e having a guide portion 32c for increasing the surface area when it comes into contact with the holding portion and making it slidable. A holding portion 32f is formed in the .

図５に示すように、保持部２３、補助部材本体５１、クリップ３２にはそれぞれ符号２３ａ，２３ａ，５１ａ、３２ｄ（上側）で示される貫通孔が、ボルト４０のねじ部４２よりも大経で形成され、これらの貫通孔に対してボルト４０がその長手直交方向に変位できるようになっている。ボルト４０が頭部４１‘の位置から締め付けられて符号４１まで移動すると、ばね部２１’も符号２１の位置まで移動する。このとき、ボルト４０のねじ部４２は雌ねじ部３１ａとの螺合で尖り部４３が下方に突き出され、平坦部２１ｂを圧縮してばね部２１を弾性変形させる。このとき、ばね部材２０は連結部で片持ち状になっているので、保持部２３の貫通孔２３ａに対する水平方向の位置も変わり得るが、緩み止めナット３１が直接小面積で保持部２３に接触せずに先の板状部３２ａで広い面積で接触抵抗を分散させて接触するため、雌ねじ部３１ａのねじ軸心（ボルト４０のねじ軸心と同じ）に対する直交方向（以下、「ねじ軸心直交方向」）に相対移動する。その結果、雌ねじ部３１ａと尖り部４３との間のボルト４０を介したねじ軸心直交方向の突っ張りは緩和され、ボルト４０の回動トルクは、ばね部２１の弾性変形を反映することとなる。したがって、ボルト４０を適正トルクで締め付ければ、ばね部２１の適正な弾性変形が生じ、適正な圧力でパネル２００がフランジと補助部材５０との間で固定される。しかも、この固定状態は、緩み止めナットのゆるみ止め部３１ｂで維持される。 As shown in FIG. 5, through holes 23 a, 23 a, 51 a, and 32 d (upper side) are formed in the holding portion 23 , the auxiliary member main body 51 , and the clip 32 , respectively, and have a larger diameter than the threaded portion 42 of the bolt 40 . These through holes allow the bolt 40 to be displaced perpendicularly to its longitudinal direction. When the bolt 40 is tightened from the position of the head 41 ′ and moves to 41 , the spring portion 21 ′ also moves to the position of 21 . At this time, the threaded portion 42 of the bolt 40 is screwed with the female threaded portion 31a so that the pointed portion 43 protrudes downward, compressing the flat portion 21b and elastically deforming the spring portion 21 . At this time, since the spring member 20 is cantilevered at the connecting portion, the horizontal position of the holding portion 23 with respect to the through hole 23a may change, but the locking nut 31 directly contacts the holding portion 23 in a small area. In order to disperse the contact resistance over a wide area and make contact with the plate-like portion 32a without bending, the direction perpendicular to the screw axis of the female screw portion 31a (same as the screw axis of the bolt 40) (hereinafter referred to as "screw axis relative movement in the “perpendicular direction”). As a result, tension in the direction orthogonal to the screw axis through the bolt 40 between the female threaded portion 31 a and the pointed portion 43 is relieved, and the rotational torque of the bolt 40 reflects the elastic deformation of the spring portion 21 . . Therefore, if the bolts 40 are tightened with proper torque, proper elastic deformation of the spring portion 21 occurs, and the panel 200 is fixed between the flange and the auxiliary member 50 with proper pressure. Moreover, this fixed state is maintained by the locking portion 31b of the locking nut.

施工に際しては、フランジ１０１に貫通孔５１ａを形成して、固定ボルト５２及び緩み止めナット５３で補助部材本体５１を固定する。つぎに、保持部２３の下側部に誘導部３２ｃを利用して雌ねじ部材３０のクリップ３２を挟み込み保持部３２ｆに挿入する。そして、この保持部３２を先の補助部材本体５１に差し込み、貫通孔２３ａ，２３ａ，５１ａ、３２ｄ、３２ｄを貫通させて緩み止めナットにボルト４０を螺合させ、締め付ける。ボルト４０の尖り部４３は貫通孔である係止部２１ｃに嵌合し、さらに平坦部を押し下げる。雌ねじ部材３０は保持部２３及び補助部材本体５１に対してねじ軸心直交方向に相対的に微小移動し、ボルト４０の回動を阻害しない。そして、ボルト４０を適正トルクになるまでトルク．スパナ等で締め上げて、設置は完了する。このような施工手順により、ボルト突き出し量ｓが変わっても、ばね部厚さｔが一定に維持されれば、適正な押し付け圧力を作用させることができる。 During construction, a through hole 51 a is formed in the flange 101 and the auxiliary member main body 51 is fixed with a fixing bolt 52 and a locking nut 53 . Next, the clip 32 of the female screw member 30 is inserted into the holding portion 32f by using the guiding portion 32c on the lower side portion of the holding portion 23. As shown in FIG. Then, the holding portion 32 is inserted into the auxiliary member main body 51, the through holes 23a, 23a, 51a, 32d, and 32d are penetrated, and the bolt 40 is screwed to the locking nut and tightened. The pointed portion 43 of the bolt 40 is fitted in the locking portion 21c, which is a through hole, and pushes down the flat portion. The female screw member 30 moves slightly in the direction orthogonal to the screw axis relative to the holding portion 23 and the auxiliary member main body 51 so as not to hinder the rotation of the bolt 40 . Then, the torque of the bolt 40 is increased until the proper torque is obtained. Tighten with a spanner or the like to complete the installation. By such a construction procedure, even if the bolt projection amount s changes, if the spring portion thickness t is maintained constant, an appropriate pressing pressure can be applied.

以下に本発明の他の実施形態の可能性について記載する。上記実施形態と同様の部材には同じ符号を附してある。 Other possible embodiments of the invention are described below. The same reference numerals are attached to the same members as in the above embodiment.

図６では、先の補助部材本体５１を用いないで、フランジ１０１に貫通孔１０１ｂを形成してパネルの固定具1を取り付けてある。この貫通孔１０１ｂ及び上述の他の貫通孔とねじ部４２とのクリアランスは上述と同じである。 In FIG. 6, without using the auxiliary member main body 51, a through hole 101b is formed in the flange 101 to attach the fixing member 1 of the panel. The clearance between this through-hole 101b and other through-holes described above and the threaded portion 42 is the same as described above.

図７では、クリップ３２の保持部３２ｆ’が上記実施例より上下に幅広で、裏板状部３２ｅ’３２ｅ’が例えばスリット３２ｇを有し、保持部２３の上下から加え込まれる部分が異なる。 In FIG. 7, the holding portion 32f' of the clip 32 is vertically wider than that of the above embodiment, the back plate-like portion 32e' and 32e' have, for example, a slit 32g, and the portions added from above and below the holding portion 23 are different.

図８では、フランジ１０１への補助部材本体５１の取り付けに先立ち、フランジにクリップ５４を固定した緩み止めナット５３よりなる雌ねじ部材５５を用いる点が異なる。この実施形態では、クリップ５４は、板状部５４ａ、折り返し部５４ｂ、誘導部５４ｃ、貫通孔５４ｄ、裏板状部５４ｅ、保持部５４ｆを有しており、保持部５４ｆでフランジに仮止めすることにより、緩み止めナット５３を落下させずに補助部材５０を取り付けられて便利である。 8 is different in that prior to attaching the auxiliary member main body 51 to the flange 101, a female screw member 55 consisting of a locking nut 53 with a clip 54 fixed to the flange is used. In this embodiment, the clip 54 has a plate-like portion 54a, a folded portion 54b, a guide portion 54c, a through hole 54d, a back plate-like portion 54e, and a holding portion 54f.
