Description

本発明は、面板上で中空部が並設した形状を有する中空パネル構造体に係り、特に、鉄道車両の側構体、妻構体、屋根構体などに利用される中空パネル構造体に関するものである。   The present invention relates to a hollow panel structure having a shape in which hollow portions are arranged side by side on a face plate, and more particularly to a hollow panel structure used for a side structure, a wife structure, a roof structure, and the like of a railway vehicle.

従来、このような分野の技術として、特開２０００−２４７２２７号公報がある。この公報に記載されたパネル構造体は、外板に対して波板の谷部がスポット溶接され、内板に対して波板の頂部がスポット溶接されている。その結果、外板と内板との間で中空部が並設されたパネル構造体が形成される。そして、この中空部内には断熱材や配線などが装填される。このようなダブルスキンタイプのパネル構造体は、骨組みを不要にし、鉄道車両の軽量化にも寄与する。   Conventionally, there is JP 2000-247227 A as a technology in such a field. In the panel structure described in this publication, a trough portion of the corrugated plate is spot welded to the outer plate, and a top portion of the corrugated plate is spot welded to the inner plate. As a result, a panel structure in which hollow portions are arranged in parallel between the outer plate and the inner plate is formed. The hollow portion is filled with a heat insulating material, wiring, or the like. Such a double skin type panel structure eliminates the need for a framework and contributes to the weight reduction of the railway vehicle.

特開２０００−２４７２２７号公報JP 2000-247227 A

しかしながら、前述した従来の中空パネル構造体は、外板と内板との間で波板をサンドイッチする形状をなしているので、外板の大きさに合致した波板を準備する必要があり、外板が大型化すればするほど波板も大型化させる必要が生じ、これに伴って波板の取り扱い作業性が悪くなり、その結果として、中空パネル構造体の組立て作業性が悪くなる場合がある。   However, since the conventional hollow panel structure described above has a shape in which the corrugated sheet is sandwiched between the outer plate and the inner plate, it is necessary to prepare a corrugated sheet that matches the size of the outer plate, As the outer plate becomes larger, the corrugated plate needs to be enlarged, and as a result, the handling workability of the corrugated sheet deteriorates, and as a result, the assembly workability of the hollow panel structure may deteriorate. is there.

本発明は、組立て作業性の良好な中空パネル構造体を提供することを目的とする。   An object of this invention is to provide the hollow panel structure body with favorable assembly workability | operativity.

本発明に係る中空パネル構造体は、並設された中空部を有する中空パネル構造体において、断面Ｚ形状のリブ材を面板の内面側で複数連結し、一方のリブ材の一方の遊端は、隣接する他方のリブ材に固定され、一方のリブ材の他方の遊端は、面板の内面に固定され、面板に固定された一方のリブ材と他方のリブ材との協働で中空部が形成されていることを特徴とする。   A hollow panel structure according to the present invention is a hollow panel structure having hollow portions arranged side by side, wherein a plurality of rib members having a Z-shaped cross section are connected on the inner surface side of the face plate, and one free end of one rib member is The other free end of one rib member is fixed to the inner surface of the face plate, and the hollow portion is formed by the cooperation of the one rib member and the other rib member fixed to the face plate. Is formed.

この中空パネル構造体において、一方の断面Ｚ形状リブ材の一方の遊端を、隣接する他方の断面Ｚ形状リブ材に固定する作業と、一方のリブ材の他方の遊端を面板の内面に固定する作業と、を面板の全面に渡って順次行っていくことで、面板上で中空部を順次成形しながら、中空のパネル構造体が製作される。中空パネル構造体は、リブ材を面板に順次接合しながら製作されるので、面板の長さに応じた本数のリブ材を準備すればよい。そして、リブ材を順次連結させることによって、中空部が順次作り出されることになり、組立て作業の単純化が図られることで、中空パネル構造体の組立て作業性が良好になる。さらに、このような中空パネル構造体は、捻り剛性が高く、パネルの薄型化をも可能にする。   In this hollow panel structure, one free end of one cross-sectional Z-shaped rib member is fixed to the other adjacent cross-sectional Z-shaped rib member, and the other free end of one rib member is fixed to the inner surface of the face plate. By sequentially performing the fixing operation over the entire surface of the face plate, a hollow panel structure is manufactured while the hollow portions are sequentially formed on the face plate. Since the hollow panel structure is manufactured by sequentially joining the rib members to the face plate, the number of rib members corresponding to the length of the face plate may be prepared. Then, by sequentially connecting the rib members, hollow portions are sequentially created, and the assembly work is simplified, so that the assembly workability of the hollow panel structure is improved. Further, such a hollow panel structure has a high torsional rigidity, and enables a thin panel.

また、リブ材は、面板の内面に対して離間し且つ略平行に延在する第１のフランジ部と、面板の内面に当接すると共に、第１のフランジ部に対して略平行に延在する第２のフランジ部と、第１のフランジ部と第２のフランジ部とを連結するウェブとからなると好適である。このような構成を採用すると、リブ材を順次連結させることによって、所定形状の中空部が順次作り出されると同時に、面板と略平行な面が第１のフランジ部によって作り出されることになり、中空パネル構造体の表面と裏面とが略平行な平板状のパネル構造体を容易に製作することができる。   In addition, the rib member is in contact with the inner surface of the face plate and is spaced apart from the inner surface of the face plate and extends substantially parallel to the inner surface of the face plate, and extends substantially parallel to the first flange portion. It is preferable that the second flange portion and a web connecting the first flange portion and the second flange portion are included. By adopting such a configuration, by sequentially connecting the rib members, a hollow portion having a predetermined shape is sequentially created, and at the same time, a surface substantially parallel to the face plate is created by the first flange portion. A flat panel structure in which the front surface and the back surface of the structure are substantially parallel can be easily manufactured.

また、第１のフランジ部のウェブ側の端部には、次位のリブ材の第１のフランジ部の遊端が載置される肩部が設けられ、肩部は、第１のフランジ部の厚み分だけ第１のフランジ部の平面部から一段下げられていると好適である。このような肩部は、次位のリブ材の第１のフランジ部の遊端の載置場所の目安にすることができ、作業性の向上に寄与する。さらに、肩部は、第１のフランジ部の厚み分だけ第１のフランジ部の平面部から一段下げられており、このことは、中空パネル構造体の表面を略フラットな面にする上で極めて効果的である。   Also, the end of the first flange portion on the web side is provided with a shoulder portion on which the free end of the first flange portion of the next rib member is placed, and the shoulder portion is the first flange portion. It is preferable that the thickness of the first flange portion is lowered by one step by an amount equal to the thickness of the first flange portion. Such a shoulder portion can be used as a guide for placing the free end of the first flange portion of the next rib member, which contributes to improvement in workability. Further, the shoulder portion is lowered by one step from the flat portion of the first flange portion by the thickness of the first flange portion, which is extremely important for making the surface of the hollow panel structure substantially flat. It is effective.

また、一方のリブ材は、他方のリブ材に対して肉厚で形成されていると好適である。このような構成は、強度の必要な箇所の補強をリブ材の肉厚の変化により容易に達成している。   Further, it is preferable that one rib member is formed thicker than the other rib member. Such a configuration easily achieves reinforcement of a portion requiring strength by changing the thickness of the rib material.

本発明によれば、良好な組立て作業性を可能にしている。   According to the present invention, good assembly workability is possible.

以下、図面を参照しつつ本発明に係る中空パネル構造体の好適な実施形態について詳細に説明する。   Hereinafter, preferred embodiments of a hollow panel structure according to the present invention will be described in detail with reference to the drawings.

（第１の実施形態）
図１及び図２に示された中空パネル構造体１は、鉄道車両の側構体、妻構体、屋根構体及び屋根構体などに適用可能である。中空パネル構造体１は、ステンレス材によって構成され、面板の一例である外板２と、外板２の裏面（内面）２ａ側に溶接されている断面ハット形状の端材４と、外板２の略全面に渡って長手方向に並設された断面Ｚ形状のリブ材３とから主として構成されている。そして、鉄道車両の構体で中空パネル構造体１を利用するにあたって、リブ材３が上下方向に延在するように配置させるか、水平方向に延在するように配置させるかは、構造力学的見地から適宜判断される。 (First embodiment)
The hollow panel structure 1 shown in FIGS. 1 and 2 can be applied to a side structure, a wife structure, a roof structure, a roof structure, and the like of a railway vehicle. The hollow panel structure 1 is made of a stainless material, and includes an outer plate 2 that is an example of a face plate, a cross-sectional hat-shaped end member 4 welded to the back surface (inner surface) 2 a side of the outer plate 2, and the outer plate 2. And the rib material 3 having a Z-shaped cross section arranged in parallel in the longitudinal direction over substantially the entire surface. When using the hollow panel structure 1 in the structure of a railway vehicle, whether the rib member 3 is arranged to extend in the vertical direction or the horizontal direction is determined from the structural mechanical viewpoint. As appropriate,

ステンレス製の外板（面板）２の端部には、全幅に渡って延在するステンレス製の断面ハット形状の端材４が配置されている。端材４は、断面コ字状の本体部４ａと、本体部４ａから突出する左右一対のフランジ部４ｂとからなり、各フランジ部４ｂと外板２とはレーザ連続溶接により接合されている。さらに、外板２に固定された端材４には、断面Ｚ形状のリブ材３が溶接されている。   At the end of the stainless steel outer plate (face plate) 2, a stainless steel cross section hat-shaped end material 4 extending over the entire width is disposed. The end material 4 includes a main body portion 4a having a U-shaped cross section and a pair of left and right flange portions 4b protruding from the main body portion 4a. The flange portions 4b and the outer plate 2 are joined by laser continuous welding. Further, a rib member 3 having a Z-shaped cross section is welded to the end member 4 fixed to the outer plate 2.

図２及び図３に示すように、リブ材３は、外板２の内面２ａに対して離間し且つ略平行に延在する第１のフランジ部３ａと、外板２の内面２ａに当接すると共に、第１のフランジ部３ａに対して略平行に延在する第２のフランジ部３ｂと、第１のフランジ部３ａと第２のフランジ部３ａとを連結すると共に、外板２の内面ａに対して直交して延在するウェブ３ｃとからなる。このようなリブ材３を、レーザ連続溶接で順次連結させることによって、矩形の中空部Ｓが順次作り出されると同時に、外板２と略平行な面が第１のフランジ部３ａによって作り出される。このような形状のリブ材３は、表面と裏面とが略平行な平板状のパネル構造体を製作する際に適している。   As shown in FIGS. 2 and 3, the rib member 3 is in contact with the first flange portion 3 a that is separated from the inner surface 2 a of the outer plate 2 and extends substantially in parallel, and the inner surface 2 a of the outer plate 2. In addition, the second flange portion 3b extending substantially parallel to the first flange portion 3a, the first flange portion 3a and the second flange portion 3a are coupled, and the inner surface a of the outer plate 2 is connected. The web 3c extends orthogonally to the web. By sequentially connecting such rib members 3 by laser continuous welding, rectangular hollow portions S are sequentially created, and at the same time, a surface substantially parallel to the outer plate 2 is created by the first flange portion 3a. The rib material 3 having such a shape is suitable for manufacturing a flat panel structure in which the front surface and the back surface are substantially parallel.

さらに、第１のフランジ部３ａのウェブ３ｃ側の端部には肩部３ｄが設けられ、肩部３ｄは、第１のフランジ部３ａの厚み分だけ第１のフランジ部３ａの平面部３ａＡから一段下げられている。このような肩部３ｄは、次位のリブ材の第１のフランジ部の遊端の載置場所の目安にすることができ、組立て作業性の向上に寄与している。さらに、肩部３ｄは、第１のフランジ部３ａの厚み分だけ第１のフランジ部３ａの平面部３ａＡから一段下げられている。このことは、中空パネル構造体１の表面を略フラットな面に形成する際に効果的である。このようなリブ材３は、外面２の内面２ａ側で連続的に複数連結され、これによって、中空パネル構造体１は、中空部Ｓを長手方向に並設させた構成になる。   Further, a shoulder portion 3d is provided at the end of the first flange portion 3a on the web 3c side, and the shoulder portion 3d extends from the flat surface portion 3aA of the first flange portion 3a by the thickness of the first flange portion 3a. It is lowered one step. Such a shoulder portion 3d can be used as a guide for placing the free end of the first flange portion of the next rib material, and contributes to an improvement in assembling workability. Furthermore, the shoulder portion 3d is lowered by one step from the flat surface portion 3aA of the first flange portion 3a by the thickness of the first flange portion 3a. This is effective when the surface of the hollow panel structure 1 is formed into a substantially flat surface. A plurality of such rib members 3 are continuously connected on the inner surface 2a side of the outer surface 2, whereby the hollow panel structure 1 has a configuration in which the hollow portions S are juxtaposed in the longitudinal direction.

図２に示すように、一方のリブ材３Ａの第１のフランジ部３Ａａの遊端は、隣接する他方のリブ材３Ｂの肩部３Ｂａにレーザ連続溶接（図４参照）を介して固定され、一方のリブ材３Ａの第２のフランジ部３Ａｂは、外板２の内面２ａにレーザ連続溶接を介して固定され、外板２と一方のリブ材３Ａと他方のリブ材３Ｂとの協働で断面矩形の中空部Ｓが形成される。そして、外板２の略全面をリブ材３で覆うように、外板２にはリブ材３が順次溶接されていく。   As shown in FIG. 2, the free end of the first flange portion 3Aa of one rib member 3A is fixed to the shoulder portion 3Ba of the other adjacent rib member 3B through laser continuous welding (see FIG. 4). The second flange portion 3Ab of one rib member 3A is fixed to the inner surface 2a of the outer plate 2 through laser continuous welding, and the outer plate 2, one rib member 3A, and the other rib member 3B cooperate. A hollow portion S having a rectangular cross section is formed. Then, the rib material 3 is sequentially welded to the outer plate 2 so that the substantially entire surface of the outer plate 2 is covered with the rib material 3.

中空パネル構造体１は、断面Ｚ形状のリブ材３の連接によって製作されるので、外板２の長さに応じた本数のリブ材３を準備すればよい。そして、同一のリブ材３を順次連結させることによって、同一の中空部Ｓが順次作り出されることになり、このことは、組立て作業の単純化を図ることができ、中空パネル構造体１の組立て作業性を良好にしている。さらに、このような中空パネル構造体１は、捻り剛性が高く、パネルの薄型化をも可能にする。   Since the hollow panel structure 1 is manufactured by connecting the rib members 3 having a Z-shaped cross section, the number of rib members 3 corresponding to the length of the outer plate 2 may be prepared. Then, by sequentially connecting the same rib members 3, the same hollow portion S is created sequentially, which can simplify the assembling work, and the assembling work of the hollow panel structure 1. It has good characteristics. Furthermore, such a hollow panel structure 1 has high torsional rigidity, and can also make the panel thinner.

なお、図４に示すように、一方のリブ材３Ａの第１のフランジ部３Ａａの遊端は、隣接する他方のリブ材３Ｂの肩部３Ｂａに載せられる。このとき、図４に示すように、肩部３Ｂａがワーク受け台Ｗ上に配置され、レーザＬを連続的に走査する。レーザＬの走査時において、レーザＬの走査に追従して加圧ローラＲが移動する。そして、リブ材３Ａとリブ材３Ｂとをワーク受け台Ｗと加圧ローラＲとで挟み込んでいるので、レーザによる確実な連続溶接が可能になる。なお、レーザスポット溶接も可能である。   As shown in FIG. 4, the free end of the first flange portion 3Aa of one rib member 3A is placed on the shoulder 3Ba of the other adjacent rib member 3B. At this time, as shown in FIG. 4, the shoulder 3Ba is disposed on the work cradle W, and the laser L is continuously scanned. During scanning with the laser L, the pressure roller R moves following the scanning with the laser L. Since the rib material 3A and the rib material 3B are sandwiched between the workpiece cradle W and the pressure roller R, reliable continuous welding with a laser becomes possible. Laser spot welding is also possible.

（第２の実施形態）
外板２とリブ材３とで中空パネル構造体を構成させるにあたって、補強を必要とする場合がある。図５に示すように、第２の実施形態に係る中空パネル構造体８では、断面Ｚ形状のリブ材３（図３参照）の他に、段差の大きな肩部１０ｄをもった断面Ｚ形状のリブ材１０と、断面Ｚ形状の肉厚である補強用リブ材１１とを別途準備する。リブ材１０を外板２上にレーザ溶接した後、補強用リブ材１１の第１のフランジ部１１ａを、リブ材１０の第１のフランジ部１０ａに設けられた肩部１０ｄ上に載せ、第１のフランジ部１１ａの上に更に平板状のスペーサ１２を載せた状態で、三者を同時にレーザ溶接する。 (Second Embodiment)
When the outer panel 2 and the rib material 3 constitute the hollow panel structure, reinforcement may be required. As shown in FIG. 5, in the hollow panel structure 8 according to the second embodiment, in addition to the rib member 3 having a cross-section Z shape (see FIG. 3), the cross-section Z-shape having a shoulder 10 d having a large step is provided. A rib member 10 and a reinforcing rib member 11 having a Z-shaped wall thickness are separately prepared. After the rib member 10 is laser welded onto the outer plate 2, the first flange portion 11a of the reinforcing rib member 11 is placed on the shoulder portion 10d provided on the first flange portion 10a of the rib member 10, and the first The three members are simultaneously laser welded in a state where a flat spacer 12 is placed on one flange portion 11a.

この場合、リブ材１０の肩部１０ｄの段差は、補強リブ材１１の第１のフランジ部１１ａの肉厚とスペーサ１２の肉厚とを合算した量であり、スペーサ１２の肉厚は、リブ材３の第１のフランジ部３ａの肉厚と同じである。このことは、中空パネル構造体８の表面のフラット化を意図している。そして、補強用リブ１１には、肩部は設けられておらず、次位のリブ材３は補強用リブ１１の第１のフランジ部１１ａ上に配置される。なお、リブ材１０は、第１のフランジ部１０ａと第２のフランジ部１０ｂとウェブ１０ｃとから構成され、補強用リブ材１１は、第１のフランジ部１１ａと第２のフランジ部１１ｂとウェブ１１ｃとから構成されている。   In this case, the level difference of the shoulder portion 10d of the rib member 10 is the sum of the thickness of the first flange portion 11a of the reinforcing rib member 11 and the thickness of the spacer 12, and the thickness of the spacer 12 is the rib thickness. It is the same as the thickness of the first flange portion 3a of the material 3. This is intended to flatten the surface of the hollow panel structure 8. The reinforcing rib 11 is not provided with a shoulder portion, and the next rib member 3 is disposed on the first flange portion 11 a of the reinforcing rib 11. The rib member 10 includes a first flange portion 10a, a second flange portion 10b, and a web 10c, and the reinforcing rib member 11 includes a first flange portion 11a, a second flange portion 11b, and a web. 11c.

本発明は、前述した実施形態に限定されないことは言うまでもない。例えば、図６に示すように、第３の実施形態に係る中空パネル構造体２０では、パネル２０自体の厚さを変えるために、断面Ｚ形状のリブ材３に対し拡大相似形をなす断面Ｚ形状のリブ材３０が利用されている。さらに、リブ材３０の肩部３０ｄには、リブ材３０と同一形状のリブ材の第１のフランジ部が溶接される。なお、小型のリブ材３と大型のリブ材３０とは中間リブ材２５を介して連結されている。また、本発明は、鉄道車両に限定されず、バス、トラックなどにも適用できる。そして、外板（面板）２、リブ材３，１０，１１，３０及び端板４は、ステンレスに限定されず、鉄、アルミ、プラスチックなどであってもよい。   It goes without saying that the present invention is not limited to the embodiment described above. For example, as shown in FIG. 6, in the hollow panel structure 20 according to the third embodiment, in order to change the thickness of the panel 20 itself, the cross section Z that forms an enlarged similarity to the rib material 3 having a cross section Z shape. A shaped rib member 30 is used. Further, the first flange portion of the rib material having the same shape as the rib material 30 is welded to the shoulder portion 30 d of the rib material 30. The small rib member 3 and the large rib member 30 are connected via an intermediate rib member 25. Further, the present invention is not limited to a railway vehicle, but can be applied to buses, trucks, and the like. The outer plate (face plate) 2, the rib members 3, 10, 11, 30 and the end plate 4 are not limited to stainless steel, but may be iron, aluminum, plastic, or the like.

また、リブ材３にカーテンレールを設けてもよい。端材４は、パイプ材であってもよい。また、端材４とこれに隣接するのリブ材３との間に開放空間ができないように、端材４とリブ材３とを平板で架け渡してもよい。レーザを利用する場合、照射条件を最適化して外板２の表面に溶接痕が残らないようにする。レーザ溶接に限らず、電極溶接や様々な溶接方法が適用可能である。ウェブ３ｃは、外板２に対して直角である必要はなく、中空部Ｓがトラス形状になるように斜めに傾いていてもよい。その結果、高い剪断力に耐え得る中空パネル構造体が実現できる。   The rib material 3 may be provided with a curtain rail. The end material 4 may be a pipe material. Further, the end material 4 and the rib material 3 may be bridged with a flat plate so that there is no open space between the end material 4 and the adjacent rib material 3. When using a laser, the irradiation conditions are optimized so that no welding marks remain on the surface of the outer plate 2. Not only laser welding but electrode welding and various welding methods are applicable. The web 3c does not need to be perpendicular to the outer plate 2, and may be inclined obliquely so that the hollow portion S has a truss shape. As a result, a hollow panel structure that can withstand a high shearing force can be realized.
