Description

本発明は、複数の構体同士を接合して構成された交通車両の構体同士の接合構造に関するものである。   The present invention relates to a joining structure of structures of a transportation vehicle configured by joining a plurality of structures.

一般に、交通車両の構造は、大別すると、水平方向に沿う床構体及び屋根構体と、鉛直方向に沿う側構体2枚及び妻構体2枚の構体6枚による六面体構造である(例えば、下記特許文献1、2参照)。   Generally, the structure of a transportation vehicle is roughly classified into a hexahedral structure including a floor structure and a roof structure along the horizontal direction, and six structures including two side structures and two wife structures along the vertical direction (for example, the following patents). References 1 and 2).

従来、構体同士の接合構造として、溶接接合(例えば、下記特許文献2参照)がとられていた。又、他の接合構造としては、ボルトとナットによる接合(例えば、下記特許文献1、3参照)がとられていた。該ボルトとナットによる接合では、ボルトのネジ部分にナットを締め付けることにより、ボルトの軸方向に作用する力に対しては、ボルトの引張強度又は圧縮強度によって支持し、ボルトの軸方向と直交する二方向に作用する力に対しては、主にボルトのせん断強度によって支持することとなる。   Conventionally, welding joining (for example, refer to the following patent document 2) has been taken as a joining structure between structures. Moreover, as another joining structure, joining with a bolt and a nut (for example, refer to Patent Documents 1 and 3 below) has been taken. In the joining with the bolt and nut, by tightening the nut to the screw portion of the bolt, the force acting in the axial direction of the bolt is supported by the tensile strength or compressive strength of the bolt, and is orthogonal to the axial direction of the bolt. The force acting in two directions is supported mainly by the shear strength of the bolt.

ところで、溶接接合では、熱によって構体が収縮、変形するため、内装部材は構体を溶接接合した後に取り付けなければならなかった。しかし、構体を接合した後での作業では、作業スペースが構体内部に限定されて無理な姿勢で作業する必要も生じるために作業性が低下してしまう問題があった。又、溶接接合では、設備上の制限や気象上の制限から現地作業が困難なため、工場にて接合した後に現地に輸送することになるため、輸送費が増大してしまうという問題点があった。
一方、特許文献2、3のようなボルトとナットによる接合では、ボルトの軸方向に作用する力に対しては、ボルトの引張強度又は圧縮強度によって、結合強度を得ることになる。又、ボルトの軸方向と直交する二方向に作用する力に対しては、主にボルトのせん断強度によって結合強度を得ることとなる。このため、高い結合強度を得るためには、ボルトの軸部の断面積を拡大した上で、当該ボルトと接合するナットで締付ける必要があるが、ボルト及び対応するナットの大型化は、作業上、又規格上も問題があった。又、ボルトとナットによる接合では、強度上の有効断面積に対して、ボルトを挿通させる孔、ボルト頭部、及びナットをさらに大きくする必要があり、限られた接合スペースにおいて必要な強度を得る大きさにすることには限界があった。
By the way, in welding joining, since the structure contracts and deforms due to heat, the interior member has to be attached after welding the structure. However, in the work after joining the structures, the work space is limited to the inside of the structure, and it becomes necessary to work in an unreasonable posture. Also, with welding joints, field work is difficult due to equipment limitations and weather restrictions, and transporting to the site after joining at the factory results in an increase in transportation costs. It was.
On the other hand, in the joining by the bolt and the nut as in Patent Documents 2 and 3, the bonding strength is obtained by the tensile strength or the compressive strength of the bolt against the force acting in the axial direction of the bolt. In addition, for a force acting in two directions perpendicular to the axial direction of the bolt, the coupling strength is obtained mainly by the shear strength of the bolt. For this reason, in order to obtain high bond strength, it is necessary to enlarge the cross-sectional area of the shaft portion of the bolt and then tighten it with a nut to be joined to the bolt. There was also a problem with the standard. In addition, in joining with bolts and nuts, it is necessary to further increase the hole through which the bolt is inserted, the bolt head, and the nut with respect to the effective sectional area in terms of strength, and the necessary strength can be obtained in a limited joining space. There was a limit to the size.

本発明は、前述の従来技術における問題を解決するために、最小限のスペースで接合可能としつつ当該接合箇所における接合強度を向上させることが可能な交通車両の構体同士の接合構造を提供することを目的とするものである。   In order to solve the above-described problems in the prior art, the present invention provides a joining structure of transportation vehicle structures capable of improving joining strength at the joining portion while allowing joining in a minimum space. It is intended.

上記目的を達成するために、本発明は以下の手段を採用している。
すなわち、本発明に係る交通車両の構体同士の接合構造は、複数の構体同士を接合して構成された交通車両の構体同士の接合構造であって、一方の構体に設けられた凸形状の第一突合せ部、及び他方の構体に設けられた凸形状で、前記第一突合部と突き合わせた第二突合せ部と有し、前記第一突合せ部と前記第二突合せ部とにより基端から先端に向かうに従って幅が広くなるように形成された嵌合凸部と、前記嵌合凸部が嵌合した嵌合凹部を有するクリップ部材とを備え、前記第一突合せ部は、前記第二突合せ部に向けて開口する第一嵌合穴を有し前記第二突合せ部は、前記第一突合せ部に向かって突出し、前記第一嵌合穴に嵌合する突出部を有することを特徴とする。
In order to achieve the above object, the present invention employs the following means.
That is, the structure for joining the transportation vehicle structures according to the present invention is a joining structure of the transportation vehicle structures formed by joining a plurality of structures, and has a convex shape provided on one structure. A projecting shape provided on one butting part and the other structure, and having a second butting part butting with the first butting part, from the base end to the tip by the first butting part and the second butting part A fitting convex part formed so as to become wider as it goes, and a clip member having a fitting concave part fitted with the fitting convex part, and the first abutting part is formed on the second abutting part The second fitting portion has a first fitting hole that opens toward the first fitting portion, and has a protruding portion that fits into the first fitting hole.

この構成では、嵌合凸部とクリップ部材とが嵌合される方向の力に対しては、嵌合凸部とクリップ部材の間に生じる摩擦力に加えて、嵌合凸部とクリップ部材とが互いに係合することにより作用する拘束力、更には突出部のせん断強度によって結合強度を得ることができる。
又、嵌合される方向に直交する二方向のうち一方向であって、第一突合せ部と第二突合せ部とが突き合わされる方向の力に対しては、嵌合凸部とクリップ部材とが互いに係合することにより、嵌合凸部及びクリップ部材それぞれを構成する部材のせん断強度によって結合強度を得ることができる。
嵌合される方向に直交する二方向のうち他方向であって、嵌合凸部が延設される方向の力に対しては、嵌合凸部とクリップ部材の間に生じる摩擦力に加えて、突出部のせん断強度によって結合強度を得ることができる。
又、前記接合構造は、簡易な作業により成されるものなので、現地作業が可能である。
In this configuration, for the force in the direction in which the fitting projection and the clip member are fitted, in addition to the frictional force generated between the fitting projection and the clip member, the fitting projection and the clip member The coupling strength can be obtained by the restraining force acting by engaging each other and the shear strength of the protrusion.
In addition, for the force in the direction in which the first butting portion and the second butting portion are butted in one of the two directions orthogonal to the fitting direction, the fitting convex portion and the clip member By engaging each other, the coupling strength can be obtained by the shear strength of the members constituting the fitting convex portion and the clip member.
In addition to the frictional force generated between the fitting convex part and the clip member, the force in the other direction out of the two directions orthogonal to the fitting direction and extending in the fitting convex part Thus, the bond strength can be obtained by the shear strength of the protrusion.
Further, since the joining structure is formed by simple work, field work is possible.

又、前記の交通車両の構体同士の接合構造において、前記第二突合せ部は、前記突出部の基端が嵌合されて固定される第二嵌合穴を有することを特徴とする。     Moreover, in the joining structure of the structures of the transportation vehicle, the second butting portion has a second fitting hole in which a base end of the protruding portion is fitted and fixed.

この構成では、嵌合凸部とクリップ部材とが嵌合される方向の力及び嵌合される方向に直交する二方向のうち他方向であって嵌合凸部が延設される方向の力に対しては、前述のとおり、突出部のせん断強度によって結合強度を得るが、突出部が第二突合せ部にも嵌合されることにより、より強いせん断強度を得ることができる。   In this configuration, the force in the direction in which the fitting convex portion and the clip member are fitted and the force in the other direction out of the two directions orthogonal to the fitting direction and the direction in which the fitting convex portion extends. On the other hand, as described above, the bond strength is obtained by the shear strength of the protruding portion, but a stronger shear strength can be obtained by fitting the protruding portion to the second butted portion.

又、前記の交通車両の構体同士の接合構造において、前記第一突合せ部及び前記第二突合せ部は、対応する前記構体と一体に成形されていることを特徴とする。   Moreover, in the joining structure of the structures of the transportation vehicle, the first butting portion and the second butting portion are formed integrally with the corresponding structure.

この構成では、接合構造に係る接合部材である第一突合せ部及び第二突合せ部は、それぞれ対応する構体と一体で成形することができるので、接合部材の製造が容易となり、構体と接合部材との接触面における接合強度も十分に確保することができる。   In this configuration, since the first butting portion and the second butting portion, which are joining members related to the joining structure, can be formed integrally with the corresponding structures, the manufacture of the joining members is facilitated, and the structures and the joining members The bonding strength at the contact surface can be sufficiently secured.

又、本発明の交通車両は、複数の構体を備え、これら複数の構体が前記の接合構造で接合されていることを特徴とする。   The transportation vehicle of the present invention includes a plurality of structures, and the plurality of structures are joined by the joint structure described above.

この構成では、交通車両は、前記本発明の構体同士の接合構造を備えているので、強固な接合により各構体が形成される。   In this configuration, since the transportation vehicle has the structure for joining the structures of the present invention, each structure is formed by strong joining.

本発明に係る交通車両の構体同士の接合構造によれば、最小限のスペースで接合可能としつつ当該接合箇所における接合強度を向上させることができる。
また、本発明に係る交通車両によれば、強固な構造とすることができる。
According to the joining structure of the transportation vehicle structures according to the present invention, the joining strength at the joining location can be improved while enabling joining in a minimum space.
Moreover, according to the traffic vehicle which concerns on this invention, it can be set as a firm structure.

The vehicle main body 101A of the transportation vehicle 101 is configured by assembling a plurality of structures 112 to each other. The transportation vehicle 101 according to the present embodiment extends as a structure 112 in the horizontal direction, and includes a floor structure 102 and a roof structure 103 that form a lower part and an upper part, and two sheets that form a side part that extends in the vertical direction. This is a hexahedral structure having the side structure 104 and two wife structures 105 constituting the front and rear portions. And each structure 112 is joined by the joining structure 1 which has the other adjacent structure 112, the fitting convex part 11 mentioned later of this embodiment, and the clip member 51 in an edge part.

以下、側構体104と床構体102との接合箇所を例として本実施形態の接合構造1について説明する。また、以下においては、水平方向のうち、交通車両101の前後方向をY方向、幅方向をX方向、また、鉛直方向をZ方向として説明する。

また、第一突合せ部22は、本体部104aより下向きに凸形状である第一凸条部23と第一凸条部23の下端よりクリップ部材51に嵌合される方向となるX方向に突出した第二凸条部24から構成される。第二凸条部24は、基端から先端に向かうに従って幅が広くなるように形成されている。また、第一凸条部23の下端部には突き合わされる方向となるZ方向下方に向けて開口する第一嵌合穴25が設けられている。
本体部104aと第一突合せ部22とは、本体部104aのリブ104d及び第一突合せ部22が延設されるY方向に沿って押出し成形されることで、一体的に成形されている。
Hereinafter, the joint structure 1 of the present embodiment will be described by taking the joint portion between the side structure body 104 and the floor structure body 102 as an example. In the following description, the front-rear direction of the transportation vehicle 101 in the horizontal direction will be described as the Y direction, the width direction as the X direction, and the vertical direction as the Z direction.
As shown in FIG. 3, the side structure 104 includes a main body portion 104 a and a first butting portion 22 constituting the joining structure 1 that extends along the Y direction at the lower end portion of the main body portion 104 a. In the present embodiment, the main body portion 104a has a double skin structure including two plates 104b and 104c constituting the inner surface and the outer surface, and a rib 104d disposed between the plates. The rib 104d extends along the Y direction.
Further, the first butting portion 22 protrudes in the X direction, which is the direction in which the clip member 51 is fitted from the lower end of the first convex strip portion 23 and the first convex strip portion 23 that are convex downward from the main body portion 104a. It is comprised from the 2nd protruding item | line part 24 which was made. The 2nd protruding item | line part 24 is formed so that a width | variety may become large as it goes to a front-end | tip from a base end. Moreover, the 1st fitting hole 25 opened toward the Z direction lower direction used as the direction matched by the lower end part of the 1st protruding item | line part 23 is provided.
The main body portion 104a and the first butting portion 22 are integrally formed by extrusion molding along the Y direction in which the rib 104d and the first butting portion 22 of the main body portion 104a are extended.

又、床構体102は、本体部102aと、本体部102aのX方向端部にY方向に沿って延設された側梁121と、側梁121の上面にY方向に沿って延設された接合構造1を構成する第二突合せ部32とを有する。本体部102aは、本実施形態では、下面及び上面を構成する2枚の板102b、102cと、板同士の間に配設されたリブ102dとからなるダブルスキン構造となっている。リブ102dは、Y方向に沿って延設されている。
また、第二突合せ部32は、本体部102aより上方向に凸形状である第三凸条部33と第三凸条部33の上端よりクリップ部材51に嵌合される方向となるX方向に突出した第四凸条部34から構成される。第四凸条部34は、基端から先端に向かうに従って幅が広くなるように形成されている。また、第三凸条部33の上端部には突き合わされる方向となるZ方向上方に向かって突出する突出部35を設けられている。該突出部35は、第一嵌合穴25と対応した大きさとなっており、第一嵌合穴25に嵌合されている。
本体部102aと第二突合せ部32とは、本体部102aのリブ102d及び第二突合せ部32が延設されるY方向に沿って押出し成形されることで、一体的に成形されている。
The floor structure 102 is extended along the Y direction on the main body 102a, the side beam 121 extending along the Y direction at the X direction end of the main body 102a, and the upper surface of the side beam 121. And a second butting portion 32 constituting the joint structure 1. In the present embodiment, the main body portion 102a has a double skin structure including two plates 102b and 102c constituting the lower surface and the upper surface, and a rib 102d disposed between the plates. The rib 102d extends along the Y direction.
Further, the second butting portion 32 is formed in the X direction, which is a direction in which the second projecting portion 32 is fitted to the clip member 51 from the upper end of the third projecting strip portion 33 and the third projecting strip portion 33 that are convex upward from the main body portion 102a. It is comprised from the 4th protruding item | line part 34 which protruded. The 4th protruding item | line part 34 is formed so that a width | variety may become large as it goes to a front-end | tip from a base end. In addition, a protruding portion 35 that protrudes upward in the Z direction, which is a direction to be abutted, is provided on the upper end portion of the third protruding strip portion 33. The protrusion 35 has a size corresponding to the first fitting hole 25 and is fitted in the first fitting hole 25.
The main body portion 102a and the second butting portion 32 are integrally formed by extrusion molding along the Y direction in which the rib 102d and the second butting portion 32 of the main body portion 102a are extended.

嵌合凸部11は、第一突合せ部22と第二突合せ部32を、第一凸条部23と第三凸条部33、また第二凸条部24と第四凸条部34をそれぞれ突合せることにより形成されている。上述のとおり、第二凸条部24及び第四凸条部34が基端から先端に向かうに従って幅が広くなるように形成されているので、嵌合凸部11も突合せ面に則して一端から他端である嵌合される方に向かうに従って次第に幅が広くなるように形成される。   The fitting protrusion 11 includes a first protrusion 22 and a second protrusion 32, a first protrusion 23 and a third protrusion 33, and a second protrusion 24 and a fourth protrusion 34, respectively. It is formed by matching. As described above, since the second ridge portion 24 and the fourth ridge portion 34 are formed so as to increase in width from the proximal end toward the distal end, the fitting convex portion 11 also has one end along the abutting surface. The width is gradually increased from the other end toward the fitting direction, which is the other end.

第一突合せ部22又は第二突合せ部32は、構体112がアルミ等の金属成形品の場合は、それぞれ対応する構体112と一体に成形されることができる。これにより、第一突合せ部22又は第二突合せ部32の製造が容易となり、第一突合せ部22又は第二突合せ部32の基端部分における接合強度も十分に確保することができる。尚、第一突合せ部22又は第二突合せ部32は金属製品に限らず、十分な強度を得ることができれば樹脂製品等でもよい。   The first butting portion 22 or the second butting portion 32 can be integrally formed with the corresponding structure 112 when the structure 112 is a metal molded product such as aluminum. Thereby, manufacture of the 1st butt | matching part 22 or the 2nd butt | matching part 32 becomes easy, and joining strength in the base end part of the 1st butt | matching part 22 or the 2nd butt | matching part 32 can also be ensured enough. The first butting portion 22 or the second butting portion 32 is not limited to a metal product, and may be a resin product or the like as long as sufficient strength can be obtained.

クリップ部材51は、先端の開口から基端に向かうに従って幅が大きくなるような凹形状であり、嵌合凸部11に対応する形状として、嵌合凸部11と嵌合されている。   The clip member 51 has a concave shape that increases in width from the opening at the distal end toward the base end, and is fitted to the fitting convex portion 11 as a shape corresponding to the fitting convex portion 11.

次に、本実施形態の接合構造1の組み立て手順について説明する。
図5に示すように、まず、側構体104を床構体102の上方から下方へと移動させる。この際、第一突合せ部22に設けられた第一嵌合穴25に第二突合せ部32に設けられた突出部35が嵌合されるようにして、第一突合せ部22と第二突合せ部32を突き合わせる。これにより、嵌合凸部11が形成される。
Next, the assembly procedure of the joining structure 1 of this embodiment will be described.
As shown in FIG. 5, first, the side structure 104 is moved from the upper side to the lower side of the floor structure 102. At this time, the first butted portion 22 and the second butted portion are fitted such that the protruding portion 35 provided in the second butting portion 32 is fitted into the first fitting hole 25 provided in the first butting portion 22. Match 32. Thereby, the fitting convex part 11 is formed.

そして、嵌合凸部11がクリップ部材51の凹形状の部分に納まるように、嵌合凸部11のY方向における一端より、クリップ部材51を嵌合する。これにより、第一突合せ部22、第二突合せ部32、及びクリップ部材51が密着するように嵌合され、接合構造1が構成され、側構体104と床構体102とか組み立てられる。   Then, the clip member 51 is fitted from one end in the Y direction of the fitting convex portion 11 so that the fitting convex portion 11 is accommodated in the concave portion of the clip member 51. As a result, the first butting portion 22, the second butting portion 32, and the clip member 51 are fitted so as to be in close contact with each other, the joining structure 1 is configured, and the side structure 104 and the floor structure 102 are assembled.

ここで、溶接接合の場合は、工場での溶接作業を必要とするので、構体同士を接合した後に現地に輸送するため、輸送費が増大していた。しかし、接合構造1は、簡易な作業により成されるものなので、現地作業が可能であるため、溶接接合の場合と比較して輸送費を低廉な価格におさえられる。
又、ボルトとナットによる接合の場合と比較すると、ボルトの締め付けを必要としないので、作業時間を短縮することができる。
Here, in the case of welding joining, since welding work in a factory is required, since the structures are joined to each other and then transported to the site, transportation costs have increased. However, since the joining structure 1 is formed by a simple work and can be performed on-site, the transportation cost can be reduced compared with the case of welding joining.
Moreover, compared with the case of joining with a bolt and a nut, since the bolt is not required to be tightened, the working time can be shortened.

The bond strength can be obtained by the frictional force. In addition, the coupling strength can also be obtained by a restraining force that acts when the fitting convex portion 11 and the clip member 51 are engaged with each other. Furthermore, the bond strength can be obtained also by the shear strength generated according to the cross-sectional area along the X direction of the protruding portion 35.

また、嵌合される方向に直交する二方向のうち一方向であって、第一突合せ部22と第二突合せ部32とが突き合わされる方向のZ方向の力に対しては、嵌合凸部11とクリップ部材51とが互いに係合することにより嵌合凸部11とクリップ部材51をそれぞれ構成する部材のZ方向に沿う断面積に応じて生じるせん断強度によって結合強度を得ることができる。   In addition, for the force in the Z direction, which is one direction out of two directions orthogonal to the mating direction and in which the first butting portion 22 and the second butting portion 32 are butted, the fitting protrusion When the portion 11 and the clip member 51 are engaged with each other, the coupling strength can be obtained by the shear strength generated according to the cross-sectional area along the Z direction of the members constituting the fitting convex portion 11 and the clip member 51, respectively.

また、嵌合される方向に直交する二方向のうち他方向であって、嵌合凸部11が延設される方向のY方向の力に対しては、嵌合凸部11とクリップ部材51の接触面にY方向に働く摩擦力によって結合強度を得ることができる。更に、突出部35のY方向に沿う断面積に応じて生じるせん断強度によって結合強度を得ることができる。   Further, the fitting protrusion 11 and the clip member 51 are applied to the force in the Y direction in the other direction out of the two directions orthogonal to the fitting direction and extending in the fitting protrusion 11. The coupling strength can be obtained by the frictional force acting in the Y direction on the contact surface. Furthermore, the bond strength can be obtained by the shear strength generated according to the cross-sectional area along the Y direction of the protruding portion 35.

更に、X方向の力及びY方向の力に対しては、第一嵌合穴25の断面積分だけ有効にせん断強度を発揮することができる。図4に示すように、第一嵌合穴25と突出部35とは、想定される外力に応じて、所定ピッチで所定の数だけ設けることにより、必要な接合強度を得ることができる。
