Abstract

<P>PROBLEM TO BE SOLVED: To provide a sound insulation panel which prevents an inconvenience caused by repellent force of an engaging spring even if the engaging spring is abutted on each of right and left stiles. <P>SOLUTION: Each of the right and left stiles 1 has a sound insulation plate mounting portion 12 and a support fitting portion 11, and a bearing portion 4 is arranged between a portion of the support fitting portion 11, on which at least the engaging spring 5 abuts, and a flange 201 of a support 20. Thus the resilient force of the engaging spring 5 is borne by the bearing portion 4, and therefore deformation of the support fitting portion 11 due to the resilient force of the engaging spring 5 is suppressed, to thereby prevent looseness of the sound insulation panel and slipout of the engaging spring 5. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

【０００１】
【発明の属する技術分野】
本発明は、騒音防止のため道路や鉄道等の交通路の側縁に設置され、遮音板の周縁に枠体が形成された遮音パネルに関するものである。
【０００２】
【従来の技術】
従来、遮音板の周囲に枠体を取着することで形成された遮音パネルについては種々の発明がなされてきており、かかる遮音パネルは、とりわけ遮音板に透光板を用い、周囲の眺望や採光を確保できるものが数多く用いられてきている。遮音パネルは道路側縁に設置されるものであり、とりわけ高架道路などにおいて車両の衝突により遮音パネルが支柱から脱落した場合に、遮音パネルが飛散、落下して二次災害が起こるのを防止するために、遮音パネルと支柱や擁壁とを落下防止用の索条で繋ぎ、万一支柱から遮音パネルが脱落しても落下防止用の索条により飛散や落下が防止されるようになされている。
【０００３】
かかる落下防止用の索条は、一般に遮音パネルの設置後に遮音パネルの左右枠の中空部や左右枠に取り付けられたアイボルトなどに挿通されて取り付けが行われるが、防音壁の設置状況によっては、例えばＨ型鋼の支柱のフランジ間に遮音パネルの一端を挿入して取り付ける場合には支柱のフランジやウエーブと遮音パネルとの間にほとんど空間がないことがあり、かかる状況を鑑みて、前記左右枠の中空部を支柱側に開放し、落下防止用の索条の取り付けが容易となされた例が開示されている。
【０００４】
例えば特許文献１の図７において、支柱側が開放されたフレーム本体の上下両端に、ワイヤ収容空間部を閉じるように、ワイヤを挿通させるワイヤ貫通孔を備えたＬ字型のワイヤガイドが固着された透光防音パネルが開示されている。
【０００５】
また特許文献２の図１において、外側面が凹面となされて支柱側が開放された縦枠材にワイヤー挿通部が設けられ、横枠材の両端部に落下防止ワイヤーが挿通される切欠が設けられた透光性防音板が開示されている。

【発明が解決しようとする課題】
しかしながら、特許文献１及び特許文献２共に、左右の枠体を断面Ｈ型の支柱のフランジ間に挿入し、前記左右の枠体と支柱のフランジとの隙間に係止バネを嵌着して支柱に固定される場合には、ボックス形状となされ比較的強度の高い上下のフレーム又は横枠材に係止バネが当接されることを想定しており、左右の枠体には係止バネの反発力による変形等の不具合を防止する対策は特に施されていない。
【０００９】
防音壁の設置においては、断面Ｈ型の支柱のフランジ間が広く、遮音パネルと支柱のフランジとの間が広くなるために大型の係止バネを嵌着する場合があるが、そのような係止バネは抜け防止のために上下のフレーム又は横枠材より下方の左右の枠体に当接する程に深く嵌着される場合がある。係止バネの反発力に対抗する対策が特に施されていない左右の枠体に係止バネが当接されると、変形等が起こり係止バネによる係止力が低下し、遮音パネルのがたつきや係止バネの脱落が起こる恐れがある。
【００１０】
本発明は上記の如き問題点に鑑みてなされたものであり、左右の枠体に係止バネが当接されても、その反発力による不具合の発生を防止できる遮音パネルを提供せんとするものである。
【００１１】
【課題を解決するための手段】
上記課題を解決するため、本発明は以下のような構成としている。すなわち、本発明に係わる遮音パネルは、遮音板の左右及び上下のいずれかに枠体が取り付けられて形成され、左右の枠体を断面Ｈ型の支柱のフランジ間に挿入し、前記左右の枠体と支柱のフランジとの隙間に係止バネが嵌着されて支柱に固定される遮音パネルであって、前記左右の枠体は遮音板が取り付けられる遮音板取付部と、支柱のフランジ間に挿入される支柱嵌挿部とが備えられ、該支柱嵌挿部には遮音パネルが支柱に取り付けられた際に係止バネの反発力を支承する支持部が、少なくとも支柱嵌挿部に係止バネが当接する部位に設けられていることを特徴とするものである。
【００１２】
本発明によれば、左右の枠材が遮音板取付部と支柱嵌挿部とを備え、支柱嵌挿部の係止バネが当接する部位に支持部が設けられることで、支持部により係止バネの反発力が支承されることで、係止バネの反発力による支柱嵌挿部の変形が抑止され、遮音パネルのがたつきや係止バネの脱落を防止できる。
【００１３】
また前記支持部は、左右の枠体に刻設された取付溝に、上下方向に摺動可能に支持部形成部材が取り付けられていれば、係止バネが左右の枠材に当接される位置に応じて支持部の上下方向の位置を調節でき好ましい。
【００１４】
更にまた前記支持部は、上下のいずれかの枠体に刻設された押縁取付溝を用いて支持部形成部材が取り付けられたものであれば、遮音板の固定に係わる押縁取付溝が支持部の固定を兼ねることができ、支持部の固定に係わる構造が簡潔なものとなり好ましい。
【００１５】
また前記支柱嵌挿部は、断面略コ字状の形状となされ、遮音板取付部と反対側に位置する一方が開放されて開口部が形成され、支持部は該開口部の形状を保持するように且つ開口部と同じ側が開放されて設けられていれば、支持部を設けることによる落下防止用の索条の挿通における煩雑さを小さくでき好ましい。
【００１６】
また前記左右の枠材は、ビス取付部が一体に設けられ、上下いずれか少なくとも一方の枠体と突き合わせによる取り付けが可能となされていれば、左右の枠材の上下端面を斜めとすることで勾配に対応でき、勾配のある箇所に設置される遮音パネルの形成が容易なものとなり好ましい。
【００１７】
【発明の実施の形態】
本発明の実施の形態について、図面に基づき以下に具体的に説明する。
図１及び図２は、本発明に係わる実施の一形態を示す説明図である。まず図１において、遮音板３に左右枠体１及び上下枠体２が組み付けられて、遮音板の周囲に枠体が取り付けられた遮音パネルが形成される。左右枠体１及び上下枠体２にはそれぞれ枠体の長さ方向に沿って遮音板３の端部が挿入可能とされた開口溝Ｍが設けられ、この開口溝Ｍに遮音板３の端部が挿入された状態で周囲の枠体が取り付けられることで、遮音板３が左右枠体１及び上下枠体２と一体となされる。
【００１８】
ロ）は左右枠体１と上下枠体２の取付部分の詳細を示す説明図である。左右枠体１は遮音板３が挿入可能となされた開口溝Ｍを有する遮音板取付部１２と、防音壁を形成するのに支柱に嵌挿される支柱嵌挿部１１とが一体に備えられたものである。また遮音板取付部１２にはビス取付部１３が一体に設けられている。上下枠体２はボックス形状となされ、端部の支柱嵌挿部１１に相対峙する部位に上下方向に通じる切欠２１が設けられ、更に遮音板取付部１２と相対峙する面にビス孔２２が、ビス孔２２が穿設された面の外側の面には工具孔２３が穿設されている。左右枠体１と上下枠体２とが、ビス取付部１３及びビス孔２２の位置が一致するように突き合わされ、ビス孔２２に挿通されたビスＢが工具孔２３から差し入れられた工具によりビス取付部１３に螺着されることで左右枠体１と上下枠体２とは強固に固定される。
【００１９】
かかる方法で左右枠体１及び上下枠体２を固定することで、上述の勾配に対する対応が容易になる効果に加え、左右枠体１に一体に形成されたビス取付部１３にビスＢを螺着でき、固定は強固なものとなる。またビス孔２２がボックス形状となされた上下枠体２の一つの面に穿設されていることでビスＢの固定もその面になされ、従来の方法の如く左右枠体の一部を突設されてその突設させた部位にリベット等により締結する方法と較べ、ビスやリベット等が締結された部位に疲労が発生する度合いを小さくできる。
【００２０】
図２は、上記の如き構成の遮音パネルの、支柱への取り付けを示す説明図である。立設された２本の支柱２０はＨ型鋼により形成されており、フランジ２０１間に遮音パネル１０が取り付けられるが、イ）に示す如く、遮音パネル１０と共に係止バネ５が挿入され、遮音パネル１０とフランジとの間の隙間に係止バネ５が嵌着されることで、遮音パネル１０は係止バネ５の反発力によりロ）に示す如く支柱２０に圧接されがたつき等なく固定される。
【００２１】
ここで、支柱２０のフランジ２０１間に挿入される遮音パネル１の支柱嵌挿部１１に、少なくとも係止バネ５が当接される部位に予め支持部４を設けておくことで、支柱嵌挿部１１が係止バネの反発力により変形の恐れがある構造となされていても、その反発力を支持部４が支承し支柱嵌挿部１１の変形等による不具合の発生を防止することができる。
【００２２】
図３は、図２のＡ−Ａ断面における支持部の、実施の一形態を示す断面図である。左右枠体１の断面コ字状となされ、遮音板取付部１２と反対側に位置する一方が開放された開口部を有する支柱嵌挿部１１に、係止バネ５と当接する部位に支持部形成部材４Ａが取り付けられている。支持部形成部材４Ａは支柱嵌挿部１１の開口部１１１と同じ側が開放された断面く字状の形状となされて落下防止用の索条が挿通できる空間部４Ａ２が形成され、く字状の中間部は遮音板取付部１２と当接され更に補強材４Ａ１が差し渡されてく字状の形状保持が高められている。そのく字状の先端部が、支柱嵌挿部１１が変形を起こすときの支点となるコ字状の両付け根から最も距離の大きくなるコ字状の両先端部と接合されていることで、支持部形成部材４Ａが受ける応力を小さくし、支持部形成部材４Ａ及び支柱嵌挿部１１の変形の恐れを少なくできる。
【００２３】
図４は、前記支持部４の形成方法を示す説明図である。左右枠体１の支柱嵌挿部１１に取付溝１１２が刻設され、支持部形成部材４Ａに形成された嵌合部４Ａ３が取付溝１１２に嵌合されて、支持部形成部材４Ａは支柱嵌挿部１１内で上下方向に摺動可能に取り付けられる。かかる方法で予め支持部形成部材４Ａを支柱嵌挿部１１の取付溝１１２に摺動可能に取り付け、左右枠体１に上下枠体２を突き合わせてビス等により固定することで、輸送時や設置時等において上下枠体２により支持部形成部材４Ａが取付溝１１２から脱落するのを防止でき、また設置時に係止バネ５が当接する位置に応じて支持部形成部材４Ａを上下方向に移動させることができ、種々の形状又は大きさの係止バネ５に対応可能となる。
【００２４】
左右枠体１は、金属の曲げ材等を用いてもよいが、支柱嵌挿部１１や遮音板取付部１２等を有する複雑な連続した断面形状を形成する必要があることからアルミニウム、鉄鋼、ステンレス等の金属押出型材を用いるのが好ましく、軽量で強度を高くできるアルミニウム押出型材を好適に用いることができる。また支持部形成部材４Ａも同様に嵌合部４Ａ３等を有する複雑な断面形状を形成する必要があることからアルミニウム等の金属押出型材を用いるのが好ましい。また上下方向の高さｈは係止バネ５が支柱嵌挿部１１に当接する部位の上下方向の長さに応じて設定してよく、概ね１０〜１００ｍｍ程度が好適で、より好ましくは２０〜５０ｍｍ程度である。
【００２５】
図５及び図６は、本発明に係わる支持部の形成方法の、他の実施形態を示すものであり、図５において、左右枠体１と上下枠体２とは図１に示した如き形態にて固定されており、上下枠体２には遮音板３の端部が挿入される開口溝Ｍが設けられると共に、挿入された遮音板３の脱離を防止する押縁を取り付ける押縁取付溝２４が刻設されている。また上下枠体２の端部には、落下防止用を挿通する切欠き部２１が設けられている。遮音板の脱離を防止する押縁は、開口溝Ｍに遮音板３が挿入された部位に設けられるものであり、左右枠体１と当接する上下枠体２の両端付近の押縁取付溝２４は概ね何も取り付けられていない状態となっている。
【００２６】
一方の支持部形成部材４Ｂは、左右枠体１の支柱嵌挿部１１の開口部の幅と略同一の幅となされ、その幅方向の一端に、押縁取付溝２４に取り付けられた際に開口溝Ｍの開口部を塞ぐよう、取付溝４Ｂ１及び係止部４Ｂ２が設けられた断面形状となされている。また支持部４についても落下防止用の索条の挿通を妨げないように切欠き部４Ｂ３が設けられている。かかる取付溝４Ｂ１及び係止部４Ｂ２が上下枠材２の開口溝Ｍに嵌着され、左右枠体１の支柱嵌挿部１１に摺動されて嵌着されることで支持部４Ｂが設けられる。
【００２７】
図６は、支持部形成部材４Ｂが取り付けられた状態を示す遮音パネル１０の側面図であるが、切欠き部２１及び４Ｂ３に挿通された落下防止用の索条は、更に左右枠体１に取り付けられたアイボルトＥに挿通されることで遮音パネル１０の落下が防止される。取付溝４Ｂ１が押縁取付溝２４に嵌着されることで支持部形成部材４Ｂは固定されるが、更に係止部４Ｂ２により開口溝Ｍの開口部を塞ぐような形態となされことで、支持部形成部材４Ｂはより強固に固定される。かかる支持部形成部材４Ｂが左右枠体１の支柱嵌挿部１１内に位置されることで係止バネの反発力を支持部形成部材４Ｂにより支承することができる。尚、本実施形態では、支持部形成部材４Ｂは左右枠体１の上端部に設けられているが、端部から離れた部位に設けてもよい。
【００２８】
【発明の効果】
本発明によれば、左右の枠材が遮音板取付部と支柱嵌挿部とを備え、支柱嵌挿部の係止バネが当接する部位に支持部が設けられることで、支持部により係止バネの反発力が支承されることで、係止バネの反発力による支柱嵌挿部の変形が抑止され、遮音パネルのがたつきや係止バネの脱落を防止できる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound insulation panel which is installed on a side edge of a road such as a road or a railroad to prevent noise, and in which a frame is formed around a periphery of a sound insulation plate.
[0002]
[Prior art]
Conventionally, various inventions have been made for a sound insulation panel formed by attaching a frame around a sound insulation plate, and such a sound insulation panel uses a light-transmitting plate as the sound insulation plate, in particular, to provide a surrounding view and Many things that can secure lighting have been used. The sound insulation panel is installed on the side edge of the road, and prevents the sound insulation panel from scattering and falling and causing a secondary disaster, especially when the sound insulation panel falls off the pillar due to a vehicle collision on an elevated road etc. For this reason, the sound insulation panel is connected to the support or the retaining wall with a rope for preventing the fall, and even if the sound insulation panel falls off from the support, the scattering or the fall prevention rope prevents the scattering and the fall. I have.
[0003]
Such a rope for preventing fall is generally inserted and installed in the hollow portions of the left and right frames of the sound insulation panel or the eyebolts attached to the left and right frames after the installation of the sound insulation panel, but depending on the installation condition of the sound insulation wall, For example, when one end of the sound insulation panel is inserted between the flanges of the H-shaped steel column and attached, there is almost no space between the flange or the wave of the column and the sound insulation panel. An example is disclosed in which a hollow portion is opened to the column side to facilitate attachment of a rope for preventing falling.
[0004]
For example, in FIG. 7 of Patent Literature 1, an L-shaped wire guide having a wire through hole through which a wire is inserted is fixed to upper and lower ends of a frame main body whose support side is open so as to close a wire housing space. A translucent soundproof panel is disclosed.
[0005]
Further, in FIG. 1 of Patent Document 2, a wire insertion portion is provided in a vertical frame material having a concave outer surface and an open support side, and a notch is provided at both ends of a horizontal frame material through which a fall prevention wire is inserted. A transparent soundproof plate is disclosed.

[Problems to be solved by the invention]
However, in both Patent Literature 1 and Patent Literature 2, the left and right frames are inserted between the flanges of the column having the H-shaped cross section, and the locking spring is fitted into the gap between the left and right frames and the column flange. When it is fixed to the box, it is assumed that the locking spring is in contact with the upper and lower frames or the horizontal frame material that is formed in a box shape and has relatively high strength. No measures are taken to prevent problems such as deformation due to repulsion.
[0009]
In the installation of a soundproof wall, a large locking spring may be fitted because the distance between the flanges of the support having the H-shaped cross section is wide and the distance between the sound insulation panel and the flange of the support is wide. In order to prevent the spring from coming off, the spring may be fitted deep enough to abut on the left and right frames below the upper and lower frames or the horizontal frame material. If the locking springs come into contact with the left and right frames that are not specifically designed to counter the repulsive force of the locking springs, deformation and the like will occur and the locking force of the locking springs will decrease, and the sound insulation panel will be damaged. There is a danger of rattling and falling off of the locking spring.
[0010]
The present invention has been made in view of the above-described problems, and has as its object to provide a sound insulation panel that can prevent a problem caused by a repulsive force even when locking springs abut on left and right frames. It is.
[0011]
[Means for Solving the Problems]
In order to solve the above problems, the present invention has the following configuration. That is, the sound insulation panel according to the present invention is formed by attaching a frame body to either the left or right or top and bottom of the sound insulation plate, and inserting the left and right frame bodies between the flanges of the column having the H-shaped cross section. A sound insulation panel in which a locking spring is fitted in a gap between a body and a flange of a support and is fixed to the support, wherein the left and right frames are between a sound insulation plate mounting portion to which a sound insulation plate is mounted and a flange of the support. And a support portion for supporting the repulsive force of the locking spring when the sound insulation panel is attached to the support column, and the support portion is engaged with at least the support column insert portion. The spring is provided at a position where the spring contacts.
[0012]
According to the present invention, the left and right frame members are provided with the sound insulation plate mounting portion and the support fitting insertion portion, and the support portion is provided at a position where the locking spring of the support fitting insertion portion comes into contact, so that the support member is locked. By supporting the repulsive force of the spring, the deformation of the strut insertion portion due to the repulsive force of the locking spring is suppressed, and it is possible to prevent the sound insulation panel from rattling and the locking spring from falling off.
[0013]
In addition, if the supporting portion is provided with a supporting portion forming member slidably in a vertical direction in a mounting groove formed in the left and right frame bodies, the locking spring comes into contact with the left and right frame members. The vertical position of the support portion can be adjusted according to the position, which is preferable.
[0014]
Still further, if the support portion has a support portion forming member attached thereto using a ridge attachment groove formed in one of the upper and lower frames, the ridge attachment groove relating to the fixing of the sound insulation plate is a support portion. Can be also fixed, and the structure related to the fixing of the supporting portion is simple and preferable.
[0015]
The support fitting portion has a substantially U-shaped cross-section, and is open at one side opposite to the sound insulation plate mounting portion to form an opening, and the support portion retains the shape of the opening. It is preferable that the opening is provided on the same side as the opening, since the provision of the supporting portion can reduce the complexity of inserting the rope for drop prevention.
[0016]
In addition, the left and right frame members are provided with a screw mounting portion integrally, and if the upper and lower end surfaces of the left and right frame members are inclined as long as at least one of the upper and lower frames can be attached by abutting. It is preferable because it can cope with the gradient and the formation of the sound insulation panel to be installed at the location with the gradient is easy.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 and FIG. 2 are explanatory diagrams showing an embodiment according to the present invention. First, in FIG. 1, the left and right frames 1 and the upper and lower frames 2 are assembled to the sound insulating plate 3 to form a sound insulating panel in which a frame is attached around the sound insulating plate. Each of the left and right frame bodies 1 and the upper and lower frame bodies 2 is provided with an opening groove M into which an end of the sound insulating plate 3 can be inserted, along the longitudinal direction of the frame body. The sound insulating plate 3 is integrated with the left and right frames 1 and the upper and lower frames 2 by attaching the surrounding frames while the portion is inserted.
[0018]
(B) is an explanatory view showing the details of the mounting portions of the left and right frame bodies 1 and the upper and lower frame bodies 2. The left and right frame bodies 1 are integrally provided with a sound insulating plate mounting portion 12 having an opening groove M into which the sound insulating plate 3 can be inserted, and a column fitting portion 11 inserted into a column to form a soundproof wall. Things. Further, a screw mounting portion 13 is provided integrally with the sound insulating plate mounting portion 12. The upper and lower frame 2 is formed in a box shape, and a notch 21 is formed in a portion facing the column fitting insertion portion 11 at the end, and a notch 21 communicating with the vertical direction is provided. Further, a screw hole 22 is formed on a surface facing the sound insulating plate mounting portion 12. A tool hole 23 is formed on the outer surface of the surface on which the screw hole 22 is formed. The left and right frame bodies 1 and the upper and lower frame bodies 2 are abutted so that the positions of the screw mounting portion 13 and the screw holes 22 match, and the screws B inserted into the screw holes 22 are screwed by a tool inserted through the tool holes 23. The left and right frames 1 and the upper and lower frames 2 are firmly fixed by being screwed to the mounting portion 13.
[0019]
By fixing the left and right frame members 1 and the upper and lower frame members 2 by such a method, in addition to the effect of easily coping with the above-described gradient, the screw B is screwed into the screw mounting portion 13 formed integrally with the left and right frame members 1. It can be worn and the fixation is strong. Since the screw holes 22 are formed in one surface of the box-shaped upper and lower frame 2, the screws B are fixed to the surface, and a part of the left and right frames is protruded as in the conventional method. Compared with the method of fastening the projecting portion with a rivet or the like, the degree of occurrence of fatigue in the portion where the screw or rivet is fastened can be reduced.
[0020]
FIG. 2 is an explanatory diagram showing the mounting of the sound insulation panel having the above-described configuration to a support. The two upright columns 20 are formed of H-shaped steel, and the sound insulation panel 10 is mounted between the flanges 201. As shown in a), the locking spring 5 is inserted together with the sound insulation panel 10, and the sound insulation panel is inserted. Since the locking spring 5 is fitted in the gap between the flange 10 and the flange, the sound insulation panel 10 is pressed against the support 20 as shown in (b) due to the repulsive force of the locking spring 5 and is fixed without rattling or the like. You.

Here, the support portion 4 is provided in advance in at least the portion where the locking spring 5 comes into contact with the support fitting insertion portion 11 of the sound insulation panel 1 inserted between the flanges 201 of the support 20, so that the support fitting insertion can be performed. Even if the portion 11 is configured to be possibly deformed by the repulsive force of the locking spring, the repulsive force is supported by the support portion 4 and the occurrence of troubles due to the deformation of the column insertion portion 11 can be prevented. .
[0022]
FIG. 3 is a cross-sectional view showing an embodiment of the support section in the AA cross section of FIG. The right and left frames 1 have a U-shaped cross section, and the support fitting portion 11 has an opening which is opposite to the sound insulating plate mounting portion 12 and has one open end. The forming member 4A is attached. The support portion forming member 4A is formed in a rectangular shape in cross section with the same side as the opening 111 of the column fitting insertion portion 11 being opened to form a space portion 4A2 through which a rope for drop prevention can be inserted. The intermediate portion is in contact with the sound insulating plate mounting portion 12, and furthermore, the reinforcing material 4A1 is inserted, so that the shape of the U-shape is enhanced. Since the U-shaped front ends are joined to the U-shaped front ends that are the longest from the U-shaped bases that serve as fulcrums when the support fitting insertion portion 11 is deformed, The stress applied to the support portion forming member 4A can be reduced, and the risk of deformation of the support portion forming member 4A and the support column insertion portion 11 can be reduced.
[0023]
FIG. 4 is an explanatory view showing a method of forming the support portion 4. A mounting groove 112 is engraved in the support fitting insertion portion 11 of the left and right frame 1, and a fitting portion 4A3 formed in the support forming member 4A is fitted into the mounting groove 112, so that the support forming member 4A is fitted with the support. It is slidably mounted in the insertion portion 11 in a vertical direction. In this manner, the support portion forming member 4A is slidably mounted in advance in the mounting groove 112 of the column fitting insertion portion 11, and the upper and lower frame members 2 are abutted on the left and right frame members 1 and fixed with screws or the like, so that they can be transported or installed. The upper and lower frames 2 can prevent the support portion forming member 4A from dropping out of the mounting groove 112 at the time or the like, and move the support portion forming member 4A in the vertical direction according to the position where the locking spring 5 abuts during installation. It is possible to cope with the locking springs 5 having various shapes or sizes.
[0024]
The left and right frames 1 may be made of a metal bending material or the like. However, since it is necessary to form a complicated continuous cross-sectional shape having the support fitting insertion portion 11 and the sound insulating plate mounting portion 12, aluminum, steel, It is preferable to use a metal extruded material such as stainless steel, and an aluminum extruded material that is lightweight and can increase strength can be suitably used. In addition, it is preferable to use a metal extruded die such as aluminum because the support section forming member 4A also needs to form a complicated cross-sectional shape having the fitting section 4A3 and the like. The height h in the up-down direction may be set according to the length in the up-down direction of the portion where the locking spring 5 comes into contact with the column fitting insertion portion 11, and is preferably about 10 to 100 mm, more preferably about 20 to 100 mm.
