Description

本発明は、サンドイッチパネルの連結構造に関するもので、特に、貨物自動車に搭載されるウイングボデーに適用されるサンドイッチパネルの連結構造に関する。   The present invention relates to a sandwich panel connection structure, and more particularly to a sandwich panel connection structure applied to a wing body mounted on a truck.

例えば、貨物自動車に搭載されるウイングボデーは、典型的に、翼状に開閉する一対のウイングルーフを備える。ウイングボデーは、荷室の断熱性を確保するため、ウイングルーフの構成材にサンドイッチパネルを適用することが既知である。このようなウイングボデーでは、ウイングルーフの側壁を構成する側部パネルは、複数枚のサンドイッチパネルを連結することで形成される。概して、サンドイッチパネルの連結は、サンドイッチパネルの一側に接合されたアルミニウム合金製の型材（フレーム）を相互に連結することで行われる。   For example, a wing body mounted on a lorry typically includes a pair of wing roofs that open and close like a wing. It is known that a wing body applies a sandwich panel as a constituent material of a wing roof in order to ensure heat insulation of a luggage compartment. In such a wing body, the side panel constituting the side wall of the wing roof is formed by connecting a plurality of sandwich panels. In general, sandwich panels are connected by interconnecting aluminum alloy molds (frames) joined to one side of the sandwich panel.

ところで、ウイングボデーの製造工程では、側部パネルをクレーンによって吊上げる作業が発生する。側部パネルを吊上げる場合、ウイングボデーのサイズが大型になるほど、サンドイッチパネルの連結部に作用する荷重が大きくなり、連結部の強度不足が問題になる。そこで、特許文献１には、パネル本体同士の連結構造を強化させたサンドイッチパネルの連結構造（以下「従来の連結構造」という）が開示されている。   By the way, in the manufacturing process of a wing body, the operation | work which lifts a side panel with a crane generate | occur | produces. When lifting the side panel, the larger the size of the wing body, the larger the load acting on the connecting part of the sandwich panel, and the insufficient strength of the connecting part becomes a problem. Therefore, Patent Document 1 discloses a sandwich panel connection structure (hereinafter referred to as “conventional connection structure”) in which the connection structure between panel bodies is reinforced.

しかしながら、従来の連結構造では、相互のサンドイッチパネルの連結片を一対の連結板で挟持するとともにボルトおよびナットによって締結させるので、作業が煩雑で多くの工数を必要とする。また、連結部を被うカバー（化粧板）が必要であり、製造コストが増大する。さらに、従来の連結構造をウイングボデーに適用する場合、外観に晒された部分の隙間（カバーと型材との隙間）から連結部内への水の侵入を防ぐ対策が必要である。   However, in the conventional connection structure, since the connection pieces of the sandwich panels are sandwiched between the pair of connection plates and fastened by bolts and nuts, the operation is complicated and requires a lot of man-hours. In addition, a cover (decorative plate) covering the connecting portion is necessary, which increases the manufacturing cost. Furthermore, when the conventional connection structure is applied to the wing body, it is necessary to take measures to prevent water from entering the connection portion from the gap (the gap between the cover and the mold material) exposed to the appearance.

特開平１１−１８１８９７号公報Japanese Patent Laid-Open No. 11-181897

そこで本発明は、上記事情に鑑みてなされたもので、連結強度をより向上させたサンドイッチパネルの連結構造を提供することを課題としてなされたものである。   Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sandwich panel connection structure with improved connection strength.

上記課題を解決するために、本発明のサンドイッチパネルの連結構造は、サンドイッチパネルの一側に接合された連結部材が相互に連結されて連結部が構成されるサンドイッチパネルの連結構造であって、相互のサンドイッチパネルの連結部材の突合せ部に設けられてパネル板厚方向に沿って配列される複数個の櫛歯を有して、前記連結部は、一方のサンドイッチパネルの連結部材の突合せ部に配列された櫛歯と他方のサンドイッチパネルの連結部材の突合せ部に配列された櫛歯とが交互に噛合わされて構成されることを特徴とする。   In order to solve the above problems, the sandwich panel connection structure of the present invention is a sandwich panel connection structure in which connecting members joined to one side of the sandwich panel are connected to each other to form a connecting portion. A plurality of comb teeth provided at the butting portion of the connecting member of the sandwich panel and arranged along the thickness direction of the panel plate, the connecting portion being a butting portion of the connecting member of one sandwich panel The comb teeth arranged and the comb teeth arranged at the butting portion of the connecting member of the other sandwich panel are alternately meshed with each other.

次に、本実施形態の作用を説明する。なお、図４、図５は、パネル縦方向長さを実際のスケールよりも短く表した図である。
サンドイッチパネル１１，２１の連結部材１２，２２を相互に連結させるに際して、まず、図２、図４に示されるように、サンドイッチパネル１１の連結部材１２とサンドイッチパネル２２の連結部材２２とを突合せて配置する。この状態では、一方のサンドイッチパネル１１の外装板６（内装板７）と他方のサンドイッチパネル２１の外装板６（内装板７）とは同一平面上に位置している。なお、連結部材１２の歯溝３４の底部と連結部材２２の歯溝３３の底部とには、予め、接着剤が塗布される。 Next, the operation of this embodiment will be described. 4 and 5 are views in which the panel vertical length is shorter than the actual scale.
When the connecting members 12 and 22 of the sandwich panels 11 and 21 are connected to each other, first, the connecting member 12 of the sandwich panel 11 and the connecting member 22 of the sandwich panel 22 are abutted as shown in FIGS. Deploy. In this state, the exterior plate 6 (interior plate 7) of one sandwich panel 11 and the exterior plate 6 (interior plate 7) of the other sandwich panel 21 are located on the same plane. Note that an adhesive is applied in advance to the bottom of the tooth groove 34 of the connecting member 12 and the bottom of the tooth groove 33 of the connecting member 22.

次に、サンドイッチパネル１１，２１をパネル横方向へ相対移動させて連結部材１２，２２を相互に接近させる。これにより、図３、図５に示されるように、連結部材１２側の櫛歯１３，１４，１５と連結部材２２側の櫛歯２３，２４，２５とが交互に噛合わされて連結部１０が構成される。ここで、サンドイッチパネル１１とサンドイッチパネル２１とをパネル横方向へ相対移動させる過程で、連結部材１２に形成される爪部３９と連結部材２２に形成される爪部４０とでモール４１（第１モール）の括れ部４４を挟持して、連結部１０に形成されるモール保持部４５（第１モール保持部）によってモール４１を保持する。   Next, the sandwich panels 11 and 21 are moved relative to each other in the lateral direction of the panel to bring the connecting members 12 and 22 closer to each other. As a result, as shown in FIGS. 3 and 5, the comb teeth 13, 14, 15 on the connecting member 12 side and the comb teeth 23, 24, 25 on the connecting member 22 side are alternately meshed so that the connecting portion 10 is Composed. Here, in the process of relatively moving the sandwich panel 11 and the sandwich panel 21 in the lateral direction of the panel, the claw portion 39 formed on the connecting member 12 and the claw portion 40 formed on the connecting member 22 form a molding 41 (first The molding 41 is held by the molding holding part 45 (first molding holding part) formed in the connecting part 10 while sandwiching the narrow part 44 of the molding).

この実施形態では以下の効果を奏する。
本実施形態によれば、一方のサンドイッチパネル１１の連結部材１２の突合せ部に配列された櫛歯１３，１４，１５と他方のサンドイッチパネル２１の連結部材２２の突合せ部に配列された櫛歯２３，２４，２５とを交互に噛合わせて連結部１０を構成することにより、サンドイッチパネル１１とサンドイッチパネル２１とを連結させる。
これにより、連結部材１２と連結部材２２との接合面に作用させる面圧を増大させることができるとともに、連結部材１２と連結部材２２との接着面積を、従来の連結構造、例えば、凹部に凸部を嵌合させる連結構造における接着面積に対して増大させることが可能であり、連結強度（連結構造の接合強度）を大幅に向上させることができる。
その結果、連結されたサンドイッチパネル１１，２１を容易にクレーンで吊上げることが可能であり、例えば、サンドイッチパネル１１，２１を構成材に適用したウイングボデー１の製造工程を合理化することができる。また、サンドイッチパネル１１，２１の連結にボルト、ナット等の締結部材を使用しないので、作業者への負担を軽減することができる。
また、本実施形態では、一対の楔形の櫛歯１４，２４を相互に噛合わせる、換言すると、一方の連結部材１２の楔形の櫛歯１４を他方の連結部材２２の歯溝３３に嵌入させるとともに他方の連結部材２２の楔形の櫛歯２４を一方の連結部材１２の歯溝３４に嵌入させることにより、一方の連結部材１２と他方の連結部材２２とを強固に接合することが可能であり、連結構造の強度（連結部１０の強度）をより向上させることができる。 This embodiment has the following effects.
According to the present embodiment, the comb teeth 13, 14, 15 arranged at the butting portion of the connecting member 12 of one sandwich panel 11 and the comb teeth 23 arranged at the butting portion of the connecting member 22 of the other sandwich panel 21. , 24 and 25 are alternately meshed to constitute the connecting portion 10, thereby connecting the sandwich panel 11 and the sandwich panel 21.
As a result, the surface pressure acting on the joint surface between the connecting member 12 and the connecting member 22 can be increased, and the bonding area between the connecting member 12 and the connecting member 22 can be increased in a conventional connecting structure, for example, a recess. It is possible to increase the bonding area in the connection structure in which the portions are fitted, and the connection strength (joining strength of the connection structure) can be greatly improved.
As a result, it is possible to easily lift the connected sandwich panels 11 and 21 with a crane. For example, the manufacturing process of the wing body 1 using the sandwich panels 11 and 21 as components can be streamlined. Moreover, since a fastening member such as a bolt or a nut is not used for connecting the sandwich panels 11 and 21, the burden on the operator can be reduced.
In the present embodiment, the pair of wedge-shaped comb teeth 14 and 24 are engaged with each other, in other words, the wedge-shaped comb teeth 14 of one connecting member 12 are fitted into the tooth grooves 33 of the other connecting member 22. By fitting the wedge-shaped comb teeth 24 of the other connecting member 22 into the tooth groove 34 of one connecting member 12, it is possible to firmly join the one connecting member 12 and the other connecting member 22, The strength of the connection structure (strength of the connection portion 10) can be further improved.

本実施形態によれば、連結部１０の外側（外観部分）の隙間をモール４１（第１モール）によって被うようにしたので、外観品質を向上させることができるとともに水が連結部材１２，２２間の隙間から連結部１０の内側（ウイングボデー１の荷室）へ侵入することを、より確実に阻止することができる。
また、モール４１は、一方の連結部材１２と他方の連結部材２２とを連結させることにより、同時に、連結部材１２，２２間に形成されるモール保持部４５（第１モール保持部）に取り付けることができる。さらに、モール４１の括れ部４４を連結部材１２に形成される爪部３９と連結部材２２に形成される爪部４０とによって挟持したので、モール４１を強固に保持することができるとともにシール性を高めることができる。 According to this embodiment, since the gap on the outside (outer appearance part) of the connecting portion 10 is covered by the molding 41 (first molding), the appearance quality can be improved and the water can be connected to the connecting members 12 and 22. It is possible to more reliably prevent entry into the inside of the connecting portion 10 (the cargo compartment of the wing body 1) from the gap therebetween.
Moreover, the molding 41 is attached to the molding holding part 45 (first molding holding part) formed between the connecting members 12 and 22 at the same time by connecting the one connecting member 12 and the other connecting member 22. Can do. Further, since the constricted portion 44 of the molding 41 is sandwiched between the claw portion 39 formed on the connecting member 12 and the claw portion 40 formed on the connecting member 22, the molding 41 can be firmly held and has a sealing property. Can be increased.

なお、実施形態は上記に限定されるものではなく、例えば、次のように構成することができる。
連結部１０の内側（荷室側）の隙間をモール（第２モール）によって被うように構成することができる。この場合、モール（第２モール）は、モール４１（第１モール）同様に、一方の連結部材１２と他方の連結部材２２とを連結させることにより、同時に、連結部材１２，２２間に形成されるモール保持部（第２モール保持部）に取り付けられるように構成することができる。ここで、モールは、必要に応じて、連結部１０の外側と内側との少なくとも一方に取り付けられる。 In addition, embodiment is not limited above, For example, it can comprise as follows.
It can comprise so that the clearance gap inside the connection part 10 (loading room side) may be covered with a molding | mall (2nd molding). In this case, the molding (second molding) is formed between the connecting members 12 and 22 at the same time by connecting one connecting member 12 and the other connecting member 22 in the same manner as the molding 41 (first molding). It can comprise so that it may be attached to a molding holding part (second molding holding part). Here, the molding is attached to at least one of the outside and the inside of the connecting portion 10 as necessary.
