Abstract

The body of a railway vehicle is manufactured using laminated panels such as honeycomb panels. A plurality of windows on the side of the railway vehicle are provided at a constant pitch along the transverse direction of the vehicle. The side structures on the side of the vehicle are made of honeycomb panels. The length of one honeycomb panel is standardized multiple times the pitch of the window. Three honeycomb panels, four times the length of the window, are placed side by side and welded to each other, and both ends are welded to the honeycomb panel to adjust the length. Since most honeycomb panels of the side structures of the body are standardized, the body can be manufactured at low cost. The honeycomb panel structure can be converted to another vehicle for one knitted vehicle.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle having a vehicle body composed of side panels with laminated panels. In particular, the side structure of the vehicle body is constructed in accordance with a plurality of laminated panels such as a plurality of honeycomb cores (honeycomb panels), and the side structures of the vehicle body are constructed. The present invention relates to a railroad vehicle having a vehicle body configured laterally with laminated panels in which laminated panels are welded to each other.

The body of a railroad car is generally classified into various types of cars such as ordinary cars, superior cars, private cabin cars and restaurant cars. The body construction of such a railroad car is different depending on the purpose of vehicle use.

For example, the difference between the superior and ordinary cars is differentiated by changing the seat size, the distance between the front seat and the rear seat, and the size of the window. A one-piece vehicle traveling long distances is constructed by connecting various types of cars described above.

The conventional railway vehicle body structure is designed and manufactured to have each vehicle body for each use purpose, and the other conventional railway vehicle body structure is, for example, Japanese Patent Laid-Open No. 36755/1983 (European Patent EP-A1-). 0 071 689).

In the latter conventional railway vehicle, a vehicle that is suitable for the purpose of use of a vehicle is provided by making the body of the vehicle common to each other and using the vehicle body structure that can freely arrange in-vehicle installations such as seats and partition walls.

In addition, in railroad cars that run at high speed, it is required to achieve weight reduction of the vehicle body, enhancement of the rigidity of the vehicle body, and improvement of the strength of the vehicle body. From this point of view, it is required to construct a vehicle body from a laminated panel structure welded with a plurality of brazed honeycomb panels made of a light alloy such as an aluminum alloy.

The honeycomb panel constituting the vehicle body consists of a core having many hexagonal shaped cells between two faceplates and two faceplates. In addition, the thick coupling member is disposed on the outer peripheral portion between the two face plates. The two face plates, the core and the coupling member are integrated with each other by soldering.

The honeycomb panels are welded to each other in the joining member and welded to the armature such as a column, whereby a vehicle body is manufactured. A body of this type for use in a railway vehicle is described, for example, in Japanese Patent Laid-Open No. 90468/1991.

Among the conventional techniques described above, in the method of designing and manufacturing individual bodies for each use purpose, the size of the window, the distance between two adjacent windows, the installation position of the inlet and the emergency exit, etc. depend on the head car or the middle car, or the ordinary car. Depends on your car, superior car, or dining car.

Therefore, in the prior art, it is necessary to design and manufacture a completely different vehicle body for each type even in a vehicle having the same configuration, and it is difficult to reduce the design stage and manufacturing stage of the vehicle body.

Moreover, in the above-mentioned prior art, a vehicle structure forms a vehicle body in common with each other, and the latter technique which can arrange | position freely in-car installations, such as a seat and a partition wall, has the following problems. If the seating arrangement of the superior or private vehicle is changed, the distance between the front seat and the rear seat does not match the distance between two adjacent windows, which obstructs the passenger's out-of-car view. In addition, it is difficult to arrange a room such as a washroom and a cargo compartment in which the arrangement of the window is unnecessary, and the degree of freedom of the vehicle body structure is reduced.

In addition, a vacuum furnace is used to manufacture laminated panels constituting the vehicle body. Since the brazing laminated panel is manufactured by heating (about 500 degreeC-600 degreeC) in the state which compressed two faceplates in the vacuum furnace from the outside, manufacturing cost of a laminated panel becomes expensive. For this reason, it is desired to standardize the dimensions of the laminated panel in order to reduce the manufacturing cost in the vacuum furnace.

A large vehicle body is produced by welding a plurality of laminated panels. From the viewpoint of reducing the length of the weld wire of the laminated panel, it is desirable to enlarge the size of the laminated panel as much as possible. As a result, it is desirable to use laminated panels of as large dimensions as possible, and it is also desirable to standardize laminated panels in order to limit within several kinds of laminated panels.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle having a vehicle body which is configured with side panels of which laminated panels constituting the vehicle body can be standardized.

Another object of the present invention is to provide a vehicle having a vehicle body that is configured by a laminated panel in which a length of a welding line can be shortened in the laminated panel structure constituting the vehicle body.

It is still another object of the present invention to provide a vehicle having a vehicle body configured with side panels formed of laminated panels to prevent concentration of welds in the laminated panel structure.

According to the present invention, a vehicle having a vehicle body composed of laminated panels comprises: a vehicle body consisting of a floor structure, a side structure, a roof structure and an end structure; A side structure of the vehicle body composed of a laminated panel structure; A laminated panel structure of a side structure composed of a core having a plurality of cells provided between two face plates and two face plates; And a plurality of windows that are laterally arranged at substantially the same pitch in the longitudinal direction of the vehicle and provided on the laminated panel structure.

The laminated panel structure of the side structure is constructed by welding a plurality of laminated panels, and the longitudinal length of the vehicle of each of the plurality of laminated panels of the side structure is a plurality of times the window pitch.

The side structure comprises a first laminated panel group having a plurality of laminated panels, a second laminated panel group having a plurality of laminated panels, and a third laminated panel group having a plurality of laminated panels; The longitudinal length of the vehicle of the first laminated panel group is a plurality of times the pitch of the window; The longitudinal length of the second laminated panel group vehicle is the same as the longitudinal length of the first laminated panel group vehicle; The longitudinal length of the vehicle of each of the plurality of laminated panels of the third laminated panel group is equal to the longitudinal length of two adjacent windows; Each of the plurality of laminated panels of the first laminated panel group is welded in the longitudinal direction of the vehicle; Each of the plurality of laminated panels of the second laminated panel group is welded in the longitudinal direction of the vehicle; Between the first laminated panel group and the second laminated panel group, each of the plurality of laminated panels of the third laminated panel group is welded to the first laminated panel group and the second laminated panel group at the pitch of the window, respectively.

As described above, according to the present invention, the laminated panel constituting the vehicle body is standardized in the longitudinal direction of the vehicle in terms of the dimensions of the laminated panel. As a result, the laminated panel structure can be manufactured at low cost for use in the vehicle body of the vehicle.

Since the laminated panel is composed of a plurality of times the pitch of the window, the weld line length of the laminated panel structure can be shortened during the manufacturing of the vehicle body, and the vehicle body can be manufactured at low cost in view of this.

According to the present invention, since the side structure of the vehicle body used in the vehicle is composed of a plurality of laminated panels having a plurality of lengths of the pitch of the window placed side by side in the longitudinal direction of the vehicle, and then the joints are welded, the laminated panels of the vehicle body can be standardized. The welding line of the laminated panel structure can be shortened, and the vehicle body of the vehicle can be manufactured at low cost.

One embodiment of the body of the railway vehicle according to the present invention will be described with reference to FIGS. This embodiment shows a typical knitting of railway vehicles constituting one knitting vehicle.

In addition, the dividing line appears in the lower part of 2nd, 9th, 11th, 13th, and 15th, respectively. Each of the dividing lines is shown along the longitudinal direction of the vehicle, and the dividing lines have a plurality of short vertical lines which cut the dividing lines in the longitudinal direction of the side structure of the vehicle. The interval between two adjacent short vertical lines on the dividing line indicates the length (horizontal width) in the longitudinal direction of the laminated panel or the like.

First, with reference to FIGS. 1-4, the basic structure of the vehicle body of the railway vehicle of a present Example is demonstrated. In this embodiment, the ordinary car is illustrated as a combination vehicle.

The vehicle body of the ordinary vehicle has a bottom portion 30, a wall portion (referred to as a side structure) 40 extending along the longitudinal direction of the vehicle, a roof portion 60 and a gable wall portion (end structure) which closes the end portion in the longitudinal direction of the vehicle. 70). The side structure 40 of the vehicle body is generally composed of a vertical structure. The side structure 40 has a plurality of windows 42. Alternatively, on one side of the vehicle, the side structure 40 has two entrances 45E and 45F at the end side along the longitudinal direction of the vehicle. The end structure 70 is provided with the connector 72 which connects the vehicle adjacent to the both end side of a vehicle body. In this railroad car, toilets 55 and washrooms 56 are provided as service facilities.

In this embodiment of the present invention, as a constituent member of the outer panel of the side structure 40 and the roof structure 60, a laminated panel structure made of a light metal alloy such as an aluminum alloy and soldered is used.

This soldered laminated panel structure consists of two rectangular face plates, a core and a coupling member, which are soldered together to form a single piece. The core is for example a honeycomb core and is connected to two face plates. The core has a plurality of plates perpendicular to the two face plates. The engagement member is disposed on the outer side of the core and engages the two face plates.

The coupling member disposed on the end side of the laminated panel of the vehicle is welded to a frame such as a pillar and the other coupling member of the adjacent laminated panel, thereby producing one large faceplate panel structure including a side structure and a roof structure.

The vehicle body structure described above is described in, for example, Japanese Patent Laid-Open No. 90468/1991. However, since the shoulders 65 disposed on both sides of the roof structure 60 have a small radius of rotation, an extruded material is used.

Laminated panels are not used for both the left door entry unit 45A of the doorway 45E and the right door door unit 45B of the doorway 45F, but an extruded material made of aluminum alloy is used. The left door entry unit 45A is composed of a frame of the doorway 45E and a shutter-boxing 45C of a sliding door (not shown) that opens and closes the doorway 45E. The right entry and exit unit 45B is comprised of the frame of the entrance and exit 45F, and the shutter-boxing 45D of the sliding door (not shown) which opens and closes the entrance and exit 45F.

The entry and exit units 45A and 45B consist of joining members and plates made of extruded material members made of lightweight metal alloys. Each entrance 45E, 45F is provided near the longitudinal end side of the vehicle, respectively.

Between both entrances 45E and 45F arrange | positioned at the both end sides of a vehicle, the side structure 40 of a vehicle body is comprised from several laminated panel. On one side of the vehicle, a total of 14 windows 42 are provided between the doorways 45E and 45F. All windows 42 are formed at equal intervals on each laminated panel.

In this embodiment of the present invention, three kinds of laminated panels P1, P2, and P3 are arranged between two entrances 45E and 45F. The side structure 40 on one side of the vehicle is constructed by welding five laminated panels given three laminated panels P1, one laminated panel P2, and one laminated panel P3. Each of the three laminated panels P1 is formed to have the same dimension, and the laminated panel P1 includes a left laminated panel P1, an intermediate laminated panel P1, and a right laminated panel P1.

One of the three types of laminated panels is the laminated panel P1, and each of the left, middle and right laminated panels P1 has four windows 42. The length (horizontal width) in the longitudinal direction of the laminated panel P1 is four times the pitch of the two adjacent windows 42 and 42. The three honeycomb panels made up of the laminated panels P1 are laid side by side parallel to the longitudinal direction of the vehicle, as shown in FIG.

The other of the three types of laminated panels is the laminated panel P2, which is arranged between the left access unit 45A and the left laminated panel P1. Another of the three types of laminated panels is the laminated panel P3, which is disposed between the right access unit 45B and the right laminated panel P1. These five laminated panels P1, P2, and P3 are welded to form a large faceplate laminated panel structure, whereby a main part of the side structure 40 of the vehicle body is formed.

An indicator light (not shown) is provided on the side structure 40 disposed in the substantial central portion of the vehicle in the longitudinal direction, which indicates the opening and closing state of the sliding doors of the entrances 45E and 45F. Therefore, one inside the three laminated panels P1, that is, a fixing seat and a mounting hole for the indicator light on the intermediate laminated panel P1 are required.

From this point of view, the middle laminated panel P1 for installing the indicator light is different from the other two left and right laminated panels P1 and P2. However, it is possible to form mounting holes by providing mounting positions in all three laminated panels P1, in which case all three laminated panels P1 can be manufactured in the same structure.

The passageway of the cabin and the entrances 45E and 45F having a plurality of seats 52 is divided into walls 53 and 54 as shown in FIG. The sheet 52 is rotatable in which the direction of the sheet 52 can be changed by 180 degrees. The number of sheets 52 is equal to the number of windows 42, and the pitch of the two adjacent sheets 52, 52 is the same as the pitch of the two adjacent windows 42, 42. The center of each sheet 52 coincides with the center of the longitudinal length of each window 42.

The spacing between the partition wall 53 and each sheet 52a disposed on one end side and the spacing between the partition wall 54 and each sheet 52b disposed on the other end side are respectively determined by the sheet 52 (window ( 42) each larger than half the pitch. The distance from each sheet 52a disposed on the end side to the wall 53 is substantially the same as the distance from each sheet 52b disposed on the end side to the wall 54.

Since the laminated panel P3 is connected to the shutter-boxing 45D of the right entry-out unit 45B, the longitudinal length of the laminated panel P3 is shorter than the longitudinal length of the laminated panel P2.

One laminated panel P4 is provided between the left entry unit 45A and each end structure 70, and another laminated panel P5 is provided between the right entry unit 45B and each end structure 70. Each is provided. However, in the case where the gap between the right entry and exit unit 5B and each end structure 70 is narrow, it is not necessary to use the laminated panel P5, and the extruded material member made of aluminum alloy is used.

The laminated panel structure disposed on the roof structure 60 of the vehicle body is composed of four laminated panels P21, one laminated panel P22, and one laminated panel P23 having the same dimensions as shown in FIG. do. The laminated panels P22 and P23 are located at both sides of the laminated panel P21, respectively. Each of the longitudinal lengths of the laminated panel P21 is the same as the longitudinal length of the laminated panel P1 constituting the side structure 40 of the vehicle body.

The maximum dimensions of the laminated panel depend on the size and productivity of the vacuum furnace. In this embodiment of the present invention, the dimension of the laminated panel P1 has the largest dimension among the various dimensions of the laminated panel.

Next, referring to the case of the laminated panel P1, the configuration of the laminated panel in the vehicle is described with reference to FIGS. 5 to 7.

The laminated panel P1 is mainly composed of two rectangular face plates 81A and 81B, a plurality of hexagonal cores 82, four coupling members 83, four frames 84 and vertical reinforcement members 85 and 86. It is composed.

The honeycomb core 82 and the coupling member 83 are installed between the two face plates 81A and 81B. The engaging member 83 is provided along the four end circumferences of the two face plates 81A, 81B.

Each coupling member 83 has a cross-sectional structure in the form of a channel as in FIGS. 6 and 7. Coupling member 83 is composed of three sections (83a, 83b, 83c) as shown in FIG. The two parallel sections 83a and 83b of the coupling member 83 are thick enough to allow welding work. Each of the two parallel sections 83a and 83b of the coupling member 83 respectively connected to the section 83c faces outward and extends.

The section 83c of the coupling member 83 is connected to two sections 83a and 83b. This section 83c is orthogonal to the two face plates 81A and 81B and parallel to the plate of the core 82.

A rectangular frame (coupling member) 84 is provided along the four circumferences of the rectangular window 42 as in FIG. Each frame 84 has a channel-shaped cross-sectional structure and the frame 84 is composed of three sections 84a, 84b and 84c as shown in FIG. Each of the two parallel sections 84a and 84b of the frame 84 is thick enough so that a window device (not shown) can be installed there.

Two parallel sections 84a and 84b of frame 84 face the opening layer of window 42, respectively. In the two parallel sections 84a and 84b of the frame 84, the longitudinal length of the section 84a disposed on the side of the cabin is shorter than the longitudinal length of the section 84b as shown in FIG.

The vertical section 84c of the frame 84 is connected to two parallel sections 84a and 84b and the section 84c is orthogonal to the two face plates 81A and 81B. The honeycomb core 82 has many hexagonal cells, and the plates constituting the cells are perpendicular to the two face plates 81A and 81B.

Each of the three vertical reinforcement members 85 is each made of a rectangular pipe. The reinforcing member 85 lies in the middle of the two adjacent windows 42, 42. In some cases, the rectangular pipe-shaped reinforcing member 86 is disposed on the lower and upper surfaces of the window 42.

Also, in some cases, the horizontal reinforcement member is disposed between the coupling member 83 and the collection direction reinforcement members 85 and 86. The outer circumferential portion of the reinforcing member 85 is in contact with the two face plates 81A and 81B and the honeycomb core 82.

The honeycomb core 82 is achieved by two face plates 81A and 81B, four coupling members 83, four frames 84, three reinforcing members 85 and eight reinforcing members 86. Are placed in each space. The two face plates 81A and 81B are soldered with the coupling member 83, the frame 84, the reinforcing members 85 and 86 and the honeycomb core 82. The honeycomb core 82 is brazed with the vertical section of the coupling member 83, the frame 84 and the reinforcing member 85.

Next, the manufacturing process of the laminated panel P1 will be described. All coupling members 83, frames 84, reinforcing members 85 and 86 and honeycomb core 82 are placed on the lower face plate 81B and the upper face plate 81A is placed thereon. The laminated panel P1 is manufactured according to the following known manufacturing process.

If it is necessary to provide an arc panel (for example, a laminated panel for the roof structure 60 and a laminated panel for the side structure 40), the plate of the honeycomb core 82 disposed on the longitudinal direction of the vehicle Is arranged along the longitudinal direction of the vehicle and then a soldering operation is performed, after which the bending operation is started. In addition, the arc-shaped panel can be manufactured by the following process.

The lower arc face plate 81B is placed on the arc lower metal die, on which is placed a number of plates consisting of a honeycomb core 82 and a frame member 84. Next, the upper arc face plate 81A is placed thereon and then compressed by the upper metal die, and then a soldering operation is performed.

The lower metal die has a recess on the upper side, and the upper metal die has a convex on the lower side. Each of the coupling member 83, the reinforcing member 85, and the frame member 84 is formed in an arc shape in contact with the two face plates 81A and 81B.

The plates of the honeycomb core 82 arranged in the longitudinal direction of the vehicle are placed side by side in the direction perpendicular to the arc direction of the metal die (the longitudinal direction of the vehicle).

As a result, since the plate of the honeycomb core 82 is orthogonal to the arc face plate 81A, the ends of the plates of the honeycomb core 82 located on the radially inner side are in contact with each other and the radially outer side The ends of the plates of the honeycomb core 82 located at are separated from each other. In the case where the distance of the separated parts is small, the ends are joined to each other by the brazing material. Thus, an arc type laminated panel can be obtained.

At the ends of the sections 83a and 83b of the coupling member 83, adjacent junction panels, bottom structures 30, shoulders 65, access units 45A and 45B, and the like are welded to the coupling member 83, The body is made. In addition, the inner side of the difference between the coupling member 83 and the reinforcing member 85 is welded to the skeleton, and these form an installation sheet for the interior parts.

Since the vehicle body shown in FIGS. 1 to 3 has four seats 52 per row in the vehicle width direction, this vehicle body is used for ordinary vehicles.

In addition, the vehicle body shown in Figs. 8 and 9 has three seats 52 per row in the width direction of the vehicle, and the vehicle body is used for a superior vehicle. In the right car, the pitches of the two adjacent windows 42, 42 and the pitches of the two adjacent seats 52, 52 in the longitudinal direction of the vehicle are the same as those of the ordinary car, respectively.

One row of the seats 52 is three servings in the width direction of the vehicle, and the width between the width and the two adjacent seats 52, 52 in the superior vehicle in the width direction is the width between the two adjacent seats 52, 52 in the normal vehicle. Is greater than the interval. The difference from ordinary cars is that the interior of the cabin is more luxurious. The number of windows 52 in the right car is 14 and is the same as that of the ordinary car.

The superior vehicle includes a toilet 55, a washroom 56, a car cabinet 57, and a telephone room 58. These are collectively referred to as service areas. However, the ordinary car does not have a parking lot 57 and a telephone room 58. In addition, the superior car has many service facilities as described above.

The doorway 45E of the superior vehicle exists only at the left end side of the vehicle. The laminated panel structure of the side structure 40 of the vehicle body in the right car is three laminated panels P1, one laminated panel P2, one laminated panel P6, and one laminated layer as shown in FIG. It consists of panel P7.

In the laminated panel structure of the differential vehicle, three laminated panels P1 and one laminated panel P2 are commonly used for those of ordinary cars.

In the lead car, the laminated panel structure from the side of the right access unit 45B to the end structure 70 of the side of the left access unit 45A has three laminated panels P1, one laminated panel P2, and one laminated structure. It consists of laminated panel P4.

One laminated panel P4 is provided between the left entry unit 45A and each end structure 70. Three laminated panels P1, one laminated panel P2, and one laminated panel P4 are ordinary vehicles and are commonly used.

The outer side plate of the head part 59 from the right side unit 45B to the front end part is not comprised by a laminated panel. The longitudinal length of the right entry unit 45B on the side of the shutter-boxing 45c is longer than the longitudinal length of the right entry unit 45B shown in FIG.

12 and 13 show a service difference with buffet 80 and salon 85. The pitch of the window 42 and the pitch of the sheet 52 are the same as those of the ordinary car shown in FIGS. 1 and 2.

The laminated panel structure of the side structure 40 of the vehicle body consists of three laminated panels P1, one laminated panel P4, one laminated panel P8, and one laminated panel P7. Each laminated panel P1 is provided with four windows 42, respectively. The laminated panel P4 does not have a window, the laminated panel P8 has two windows 42 and the laminated panel P7 has one window 42.

Within the laminated panel structure in the service vehicle, three laminated panels P1 and one laminated panel P4 are usually used as ordinary cars.

14 and 15 show a division room difference and eight private rooms 90 are provided on the private room vehicle. The configuration of the side structure 40 in the private vehicle is the same as FIG.

As described above, since the longitudinal length of the laminated panel P1 and the like is plural times the longitudinal length of the pitch of the window 42, the laminated panel P1 and the like can be standardized. In addition, the main part of one vehicle body can be configured using the standardized laminated panel P1. In addition, since the length of the welding line for manufacturing the laminated panel structure can be shortened, the vehicle body can be produced at low cost.

The above-described vehicle is exemplified for a main vehicle in a railroad vehicle, and there may be several types of combinations, for example, integrally combined as a single vehicle in a cabin of a private room 90 and a superior vehicle. have.

In a single vehicle, a few years after the vehicle was built, changes in the balance of passengers in ordinary and superior cars, changes in the need for service facilities such as private rooms and dining rooms, and changes in the purpose of using the vehicle (limited express vehicles) For the interval difference).

Also in this case, according to the embodiment of the present invention, since the window pitch of the knitted vehicle is the same, it is possible to easily cope with the change of the internal equipment.

Another embodiment of the vehicle body of the laminated panel side configuration in the railway vehicle according to the present invention will be described with reference to FIG. In this embodiment of the present invention, the laminated panel structure disposed between the entry and exit units 45A and 45B will mainly be described.

The three-layer laminated panel structure consists of the lower part of the window 42, the upper part of the window 42, and the height part (middle part) of the window 42.

The laminated panel structure at the bottom of the window 42 is composed of four rectangular laminated panels P31, one rectangular laminated panel P32, and one rectangular laminated panel P33. Each longitudinal length of the rectangular laminated panel P31 is twice the pitch of the window 42, respectively. The laminated panel P32 is connected to the left side access unit 45A, and the laminated panel P33 is connected to the right side entrance unit 45B at the lower part of a vehicle.

The laminated panel structure of the upper part of the window 42 consists of three rectangular laminated panels P41, one rectangular laminated panel P42, and one rectangular laminated panel P43. The laminated panel P42 is connected to the left side entrance unit 45A from the upper part of a vehicle, respectively, and the laminated panel P43 is connected to the right side entrance unit 45B.

The laminated panel structure of the height part of the window 42 consists of 13 square laminated panels P51, one square laminated panel P52, and one square laminated panel P53. Each laminated panel P51 is arranged between two adjacent windows 42 and 42, respectively. The laminated panel P52 is connected to the left side entrance unit 45A at the middle part of a vehicle, respectively, and the laminated panel P53 is connected to the right side entrance unit 45B.

In addition, the laminated panel structure of the roof structure 60 of the vehicle body is composed of five rectangular laminated panels P61, one laminated panel P62 and one laminated panel P63. Each laminated panel P61 is twice as long as the pitch of the window 42.

Each laminated panel P41 has a flat structure, and the laminated panel 41 is included in the side structure 40, but the laminated panel 41 bends the upper end of the laminated panel 41 to form part of the roof structure 60. FIG. can do.

It has a channel type coupling member (83). Side structure 40 of the vehicle body is configured by coupling the coupling member 83 to each other. In addition, each of the laminated panels P31-P33, P41-43, and P51-P53 has a vertical reinforcing member 85 incorporated therein. In some cases, a horizontal reinforcing member may be provided on the laminated panel.

The window 42 is formed at a place surrounded by the laminated panel P31, the laminated panel P41, and two adjacent laminated panels P51 and P51. Window 42 is defined at a rectangular opening, as shown in FIG. 17. The engaging member 83 constituting the outer circumference of the window 42 has a shape for installing the window device. For example, like the frame (coupling member) 84 shown in FIG. 7, this changes the length of the two parallel sections 84a and 84b of the coupling member 84.

The length change of the two sections 84a and 84b of the coupling member 84 is performed by, for example, cutting the coupling member 83 of the laminated panel in which the soldering work is completed.

According to the above embodiment of the present invention, since the laminated panel structure of the side structure 40 of the vehicle body is divided into three layers of laminated panel structure in the height direction of the vehicle, each laminated panel disposed on the side structure 40 is thin. As it becomes longer, the diameter and scale of the vacuum furnace can be smaller.

In addition, since the frame of one window 42 is constituted by welding of four laminated panels P31, P41, P51, and P51, the frame of the window 42 is coupled to the end circumferential side of each laminated panel. It can be formed by the member (83). Thus, the window 42 is defined on the opening formed by four laminated panels P31, P41, P51 and P51. Therefore, it is possible to make the vehicle body have a light weight structure. For example, at the height of the window, the upper end and the lower end of the plurality of laminated panels P51 are joined by a joining member, and the obtained joined member is manufactured by soldering, and the upper panel P41 and the lower laminated panel P31 are combined. This welding operation is coupled to the soldered member.

In this case, the coupling members of the upper and lower surfaces of the window 42 are coupling members for coupling the horizontal coupling members 83 of the laminated panels P51 and P51 and the laminated panels P4 and P31, respectively. Is done. As a result, the coupling member has a double structure and increases in weight.

However, according to the embodiment of the present invention shown in FIG. 17, since the laminated panel P51 is unitarily configured, the coupling members at the upper and lower portions of the window 42 are coupled to the laminated panels P41 and P31. Since it is comprised only by the member 83, a vehicle body can be made lightweight. Since the laminated panels P31, P41, P51, and P61 are coupled, the vertical coupling member 83 and the vertical reinforcing member 85 are connected in a row in the vertical direction of the vehicle as shown in FIG. . As a result, the side structure 40 of the vehicle body and the roof structure 60 are firmly connected.

In addition, when the width (length in the longitudinal direction of the vehicle) of the laminated panel P51 disposed in the window portion is small, the reinforcing member 85 of the laminated panel P51 becomes unnecessary, and in this case, each laminated panel P51 The coupling member 83 is connected to the lower laminated panel 31 and the upper laminated panel 41 in the vertical direction of the vehicle.

The reinforcing members 85 of the laminated panels P31 and P41 are arranged to be connected to the laminated panels 51. In the case where the width (the longitudinal length of the vehicle) of the laminated panel 51 of the window portion is small, this can be constructed by using the extruded material member and the plate.

Moreover, the welding part 91C between laminated panels P61 and P61 and the welding part 91B between laminated panels P41 and P41 are shift | deviated from the longitudinal direction of a vehicle. The welded portions 91B of the laminated panels P41 and P41 and the welded portions 91A of the laminated panels P31 and P31 are further shifted in the longitudinal direction of the vehicle.

As described above, according to this embodiment of the present invention, it is possible to prevent concentration of welded portions of the laminated panel in the height direction of the vehicle.
