Description

本発明は、台枠と側構体と妻構体と屋根構体とを有す軌条車両構体の内部に、断熱や遮音および意匠性を高める機能を有す内装材を備えた軌条車両に関するものである。   The present invention relates to a rail vehicle provided with an interior material having a function of improving heat insulation, sound insulation, and design, inside a rail vehicle structure having a base frame, a side structure, a wife structure, and a roof structure.

敷設された軌道に沿って運行される軌条車両を代表する鉄道車両を例に挙げて説明する。鉄道車両構体は、一般に、床面をなす台枠と、台枠の幅方向の端部に立設されるとともに側面をなす側構体と、台枠の長手方向の端部に立設される妻構体と、側構体および妻構体の上部に備えられるとともに上面（屋根面）を構成する屋根構体とからなる。近年では、軽量化や製作性の向上を目的として、対向する２枚の面板とこれら面板同士を接続する複数のリブから成るアルミニウム合金製の中空押出形材によって、屋根構体、側構体、台枠などを構成し、鉄道車両構体に組み立てる手法が広まりつつある。   An explanation will be given by taking, as an example, a railway vehicle that represents a rail vehicle operated along a laid track. Railcar structures are generally composed of a frame that forms a floor, a side structure that forms a side surface at the end of the frame in the width direction, and a wife that stands at the end of the frame in the longitudinal direction. It consists of a structure and a roof structure which is provided at the upper part of the side structure and the wife structure and constitutes the upper surface (roof surface). In recent years, for the purpose of weight reduction and improvement of manufacturability, roof structures, side structures, underframes are made of aluminum alloy hollow extruded sections consisting of two facing face plates and a plurality of ribs connecting the face plates. Etc., and the method of assembling a railway vehicle structure is spreading.

一般的には、まず、架台の上面に、所定の形状に押出成形された押出形材をその押出方向に沿って所定の枚数配設した後、押出形材の接合面同士を突き合わせた接合線に沿って、摩擦撹拌接合あるいは溶接することによって、屋根構体、側構体、台枠などを製作する。次に、台枠の長手方向の両端部に妻構体を立設するとともに、台枠の幅方向の両端部に側構体を立設して、妻構体および側構体の下端部と台枠の端部との接続部、妻構体と側構体との鉛直方向の接続部を摩擦撹拌接合、溶接、あるいは機械的締結手段などにより接続する。最後に、妻構体および側構体の上端部に屋根構体を載置して、妻構体および側構体の上端部と屋根構体の端部との接続部を摩擦撹拌接合、溶接、あるいは機械的締結手段などにより接続して、６面体の鉄道車両構体が製作される。こうして製作される鉄道車両構体の構造は、例えば、特許文献１や特許文献２に示されている。   In general, first, after a predetermined number of extruded shapes extruded into a predetermined shape are arranged on the upper surface of the gantry along the direction of extrusion, the joining lines are formed by abutting the joining surfaces of the extruded shapes together. A roof structure, a side structure, a base frame, etc. are manufactured by friction stir welding or welding. Next, the wife structure is erected at both ends in the longitudinal direction of the frame, and the side structure is erected at both ends in the width direction of the frame, and the lower end of the wife structure and the side structure and the end of the frame The connecting portion in the vertical direction and the connecting portion in the vertical direction between the wife structure and the side structure are connected by friction stir welding, welding, mechanical fastening means, or the like. Finally, the roof structure is placed on the upper end of the wife structure and the side structure, and friction stir welding, welding, or mechanical fastening means for connecting the upper end of the wife structure and the side structure and the end of the roof structure. A hexahedral railcar structure is manufactured by connecting them. The structure of the railway vehicle structure manufactured in this way is shown in Patent Document 1 and Patent Document 2, for example.

鉄道車両構体の内部には、断熱性や遮音性を高めるとともに意匠性を備える天井パネルや側パネルなどの内装材が備えられる。鉄道車両構体の車内側の面には、これら内装材の取り付けと取り外し（必要に応じて）に供される受金が、鉄道車両構体を構成する押出形材に一体的に成型されており、この受金に内装材を機械的締結手段により取り付ける方法が広まりつつある。このような内装材の取り付け方法は、例えば、特許文献３に示されている。   Inside the railway vehicle structure, interior materials such as a ceiling panel and a side panel are provided, which enhances heat insulation and sound insulation and has design characteristics. On the inner surface of the railway vehicle structure, a receiving metal provided for the attachment and detachment (if necessary) of these interior materials is integrally formed with the extruded material constituting the railway vehicle structure. A method of attaching an interior material to the metal receiver by a mechanical fastening means is becoming widespread. Such a method of attaching the interior material is disclosed in Patent Document 3, for example.

図５を参照して、鉄道車両構体をなす側構体の車内側の面に取り付けた断熱性や遮音性を高めるとともに意匠性を備える内装材の従来の取り付け構造を示す。図５は、側構体２０の下端部と台枠１０の幅方向（矢印１１０）の端部とが溶接によって接続された接続部を鉄道車両構体の長手方向に垂直な断面で切断して拡大した断面図である。側構体２０と台枠１０とは、側構体２０の車外側の端部と台枠１０の車外側の端部とが接続部５１において接続されており、同様に、側構体２０の車内側の端部と台枠１０の車内側の端部とが接続部５２において接続されている。   Referring to FIG. 5, a conventional mounting structure for an interior material having a design property as well as a heat insulating property and a sound insulating property attached to a vehicle inner surface of a side structure constituting a railway vehicle structure is shown. FIG. 5 is an enlarged view of a connecting portion in which the lower end portion of the side structure 20 and the end portion in the width direction (arrow 110) of the frame 10 are connected by welding in a cross section perpendicular to the longitudinal direction of the railway vehicle structure. It is sectional drawing. The side structure 20 and the frame 10 are connected to each other at the end portion of the side structure 20 on the outside of the vehicle and the end portion of the frame 10 on the outside of the vehicle. The end portion and the end portion on the vehicle interior side of the underframe 10 are connected at the connection portion 52.

台枠１０の幅方向の端部の車内側には、後述する内装材である側パネル７２が固定される受金６１が、側構体２０の車内側の面に沿う態様で台枠１０を構成する中空押出形材を押出成形する際に一体に備えられている。側構体２０の上部には、前述した受金６１と対をなして側パネル７２が固定される受金（図示なし）が備えられている。
鉄道車両構体１を構成する側構体２０の車内側の面には断熱材７１が備えられたのち、断熱材７１を覆う側パネル７２が、リベットやボルトナット等の機械的結手段８１によって、受金６１などに固定されている。On the inner side of the end of the underframe 10 in the width direction, a receiver 61 to which a side panel 72 that is an interior material described later is fixed constitutes the underframe 10 in a manner along the inner surface of the side structure 20. It is provided integrally when extruding a hollow extruded profile. On the upper side of the side structure 20, a metal receiver (not shown) to which the side panel 72 is fixed in a pair with the above metal receiver 61 is provided.
After the heat insulating material 71 is provided on the inner surface of the side structure 20 constituting the railway vehicle structure 1, the side panel 72 covering the heat insulating material 71 is received by a mechanical connecting means 81 such as a rivet or a bolt and nut. It is fixed to gold 61 or the like.

しかしながら、上記の構造は以下に示す３つの問題があった。まず、側構体２０を台枠１０の幅方向の端部に接続する時の位置決め作業の際に、側構体２０に設けられた出入口等の大きな開口部のために側構体２０の剛性が低下して局所的な変形が生じるため、位置決め作業に時間を要する場合があった。加えて、台枠１０と側構体２０とを溶接する際、台枠１０に備えられる受金６１が邪魔になって、台枠１０と側構体２０の車内側の接続部を溶接する作業工数が大きくなる傾向があった。さらに、側構体２０の車内側の面に備えられる側パネル７２は、台枠１０に備えられる受金６１と、側構体２０の上部に備えられる受金（図示なし）とに跨って固定されている。この時、台枠１０と側構体２０とが精度良く組み立てられていないと、側パネル７２の位置決め作業に多くの工数を必要とするなどの不具合が生じる場合があった。   However, the above structure has the following three problems. First, during the positioning operation when connecting the side structure 20 to the end of the underframe 10 in the width direction, the rigidity of the side structure 20 is reduced due to a large opening such as an entrance / exit provided in the side structure 20. As a result, local deformation may occur, and positioning work may take time. In addition, when the frame 10 and the side structure 20 are welded, the metal receiver 61 provided in the frame 10 becomes an obstacle, and the work man-hours for welding the connection part inside the vehicle between the frame 10 and the side structure 20 are increased. There was a tendency to grow. Further, the side panel 72 provided on the inner surface of the side structure 20 is fixed across a receiver 61 provided on the underframe 10 and a receiver (not shown) provided on the upper side of the side structure 20. Yes. At this time, if the underframe 10 and the side structure 20 are not assembled with high accuracy, there may be a problem that a large number of man-hours are required for the positioning operation of the side panel 72.
