Description

The present invention relates to a railroad vehicle in which the passenger compartment is partitioned by attaching a wall panel to a bone member erected in the passenger compartment of the structure.

For railway vehicles, rooms such as a driver's cab, a machine room, a toilet, a washroom, and a telephone room are provided in the passenger compartment. FIG. 1 is a diagram showing the vicinity of the driver's cab of the railway vehicle 100. For example, in the railway vehicle 100, the vehicle interior 102 is formed by attaching the interior panel 129 (see FIG. 6) to the welded structure 101. For example, the vehicle interior 102 is divided into a driver's cab 104 and a guest room 105 by a wall surface 103, and machine rooms 110 and 111 are further divided by wall surfaces 112 and 113 behind the driver's cab 108 and the conductor's pedestal 109 in the driver's cab 104. ing. The structure 101 is provided with openings 101a and 101b for entering and exiting the driver's cab 104, and is opened and closed by the opening / closing doors 106 and 107. The wall surfaces 103, 112, and 113 are formed by a so-called panel construction method in order to reduce on-site work and shorten the construction period (see, for example, Patent Document 1 and Patent Document 2).

FIG. 6 is a diagram showing a conventional wall panel mounting structure 120 in part A of FIG. 1. Note that FIG. 6 is a view of part A in FIG. 1 viewed from the floor side (back side in the drawing), which is a mirror image of FIG. In the so-called panel construction method, the wall surface panels 121A and 121B manufactured outside the vehicle are brought into the vehicle compartment 102 (driver's cab 104) and attached to the bone members 125A and 125B. The bone member 125A is formed by fastening a mounting screw 126 inserted into an interior panel 129 attached to a structure bone (not shown) arranged inside the structure 101 to a screw seat 127 fixed to the interior panel 129. It is erected along the interior panel 129. The upper and lower ends of the bone members 125A and 125B (not shown) are welded to the structure 101. The wall surface panel 121A is attached to the outer surfaces of the bone members 125A and 125B by mounting screws 122C and 122A, respectively. Further, the wall surface panel 121B is attached to the outer surface of the bone member 125B by the mounting screw 122B.

Here, the railroad vehicle 100 is a large structure in which the structure 101 and the internal frame are welded and joined. Therefore, the structural bones and bone members 125A and 125B (not shown) may not be arranged as designed due to welding strain or the like. Further, for example, when the total length of the railroad vehicle 100 is shorter than the design, the wall surface 103 may be arranged so as to be shifted toward the driver's cab 104, and the passenger's cab 104 may be sacrificed to secure the passenger compartment 105. Further, the bone member 125A is installed with reference to the opening 101a, but when the opening 101a is tilted, the bone member 125A is tilted accordingly. In these cases, an error occurs at the position where the wall surface panels 121A and 121B are attached to the bone member 125B (hereinafter, this error is also referred to as “attachment error”).

Therefore, in the wall surface panel mounting structure 120, a gap Sy is provided between the wall surface panels 121A and 121B, and adjustment allowances X1y and X2y are provided to absorb the mounting error between the wall surface panels 121A and 121B and the bone members 125A and 125B. ing. The method of installing the wall surface panels 121A and 121B in this structure 120 will be described. Before the wall panels 121A and 121B are installed, tap holes 1253, 1251, 1252, 1231, 1232, 1233 are not provided in the bone members 125A, 125B and the screw seats 123A, 123B, 123C. In this state, for example, the operator adjusts the position of the wall surface panel 121A with respect to the bone members 125A and 125B by horizontally shifting the wall surface panel 121A within the range of the adjustment allowance X1y. After the position of the wall surface panel 121A is determined, the operator performs tap hole processing on the bone member 125B and the screw seat 123A in accordance with the position of the insertion hole 1211b of the wall surface panel 121A to form the tap holes 1251, 1231. Then, the operator inserts the mounting screw 122A into the insertion hole 1211b of the wall surface panel 121A and fastens it to the tap hole 1251 of the bone member 125B and the tap hole 1231 of the screw seat 123A. Similarly, the operator fastens the mounting screw 122C inserted through the wall surface panel 121A to the bone member 125A and the screw seat 123C. As a result, the wall surface panel 121A is attached to the bone members 125A and 125B. Further, the operator adjusts the position of the wall surface panel 121B with respect to the bone member 125B within the range of the adjustment allowance X2y, and attaches the wall surface panel 121B to the bone member 125B with the mounting screw 122B, similarly to the wall surface panel 121A. Therefore, the operator can adjust the positions of the wall surface panels 121A and 121B within the range of the adjustment allowances X1y and X2y to absorb the mounting error without cutting the wall surface panels 121A and 121B at the site.

As shown in FIG. 7, the wall surface panel mounting structure 130 in which the wall surface panels 121A and 121B are arranged inside the bone member 125Bx is also between the wall surface panels 121A and 121B, similarly to the wall surface panel mounting structure 120 shown in FIG. By providing the gap Sy to secure the adjustment allowances X1y and X2y, it is possible to absorb the attachment error between the wall surface panels 121A and 121B and the bone member 125Bx (see, for example, Patent Document 3).

Japanese Unexamined Patent Publication No. 2013-203143 Japanese Unexamined Patent Publication No. 2004-338649 Japanese Unexamined Patent Publication No. 2010-269615

However, in the conventional wall panel mounting structures 120 and 130, if the adjustment allowances X1y and X2y of the wall panels 121A and 121B are sufficiently secured, the wall panels 121A and 121B cannot be installed with good appearance.

Specifically, the wall surface panels 121A and 121B shown in FIGS. 6 and 7 are provided with end surfaces 1213 in the lateral width direction at right angles to the edge portions 1211a and 1212a of the panel surfaces 1211 and 1212, respectively. It was. In the wall surface panel mounting structure 120 shown in FIG. 6, when the abutting portion of the wall surface panels 121A and 121B is viewed from the protruding corner side, the edge portions 1211a and 1211a of the wall surface panels 121A and 121B directly appear, and the edge portions 1211a and 1211a thereof appear directly. The gap Sy formed between the two was completely visible. Therefore, in the wall panel mounting structure 120, if the width W1y of the gap Sy is widened in order to secure a large adjustment allowance X1y and X2y, the boundary between the wall panels 121A and 121B becomes conspicuous, and the wall panels 121A and 121B can be installed in a good-looking manner. There wasn't. On the other hand, if the width W1y of the gap Sy is narrowed to improve the appearance, the adjustment allowances X1y and X2y are insufficient, and the wall surface panels 121A and 121B may interfere with each other. Therefore, in the conventional wall surface panel mounting structure 120, it is difficult to sufficiently secure the adjustment allowances X1y and X2y while improving the appearance of the butted portions of the wall surface panels 121A and 121B seen from the protruding corner side. Similarly, in the wall panel mounting structure 130 shown in FIG. 7, it was difficult to sufficiently secure the adjustment allowances X1y and X2y while improving the appearance when viewed from the inside corner side.

Further, for example, in the railway vehicle 100, the bone member 125A and the wall surface panel 121A are installed based on the opening 101a. Therefore, when the opening 101a is installed at an angle, the bone member 125A is arranged at an angle following the opening 101a, and as shown in FIG. 8, the wall surface panel 121A is attached to the bone member 125B in an inclined state. .. In this case, as shown in FIG. 8, in the abutting portion of the wall surface panels 121A and 121B, the edge portion 1211a of the wall surface panel 121A and the edge portion 1211a of the wall surface panel 121B are bone members 125B when viewed from the protruding corner side. Since it appears as a straight line on the upper side, it was easy to understand at a glance that there is a difference between the upper width W1ay and the lower width W1by of the gap Sy. Therefore, the inclination of the wall surface panel 121A was easily noticeable.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a railway vehicle that can be installed with a good-looking wall panel even if a sufficient adjustment allowance is secured.

One aspect of the present invention has the following configuration.
(1) Adjustment including a structure, a bone member installed in the structure, and a wall surface panel attached to the bone member to partition the vehicle interior to absorb an attachment error between the bone member and the wall surface panel. in railway vehicle generations is provided, wherein the wall panel is butted at an angle, to form the interior corner structure or external corner structure together with the bone member, the end face of the lateral width direction both end portions of said wall panels, Each is characterized in that it is provided in an arc shape that protrudes outward in the width direction. Here, the "arc-shaped" end face includes not only an end face having a completely arc-shaped cross section but also an end face having a flat surface at the tip portion.

In the above configuration, when the position of the bone member installed in the structure is different from the design due to welding distortion or the like, the wall panel is adjusted in position with respect to the bone member within the adjustment allowance, and becomes the bone member. It is attached. As a result, the mounting error between the bone member and the wall surface panel is absorbed. In this case, the end face of the wall surface panel is provided in an arc shape protruding outward in the width direction, and protrudes from the edge portion of the panel surface located on the bone member side toward the adjustment margin side. The width of the gap formed between the wall panel and the adjacent member is smaller than the width of the gap provided between the wall surface panel and the adjacent member in order to form the adjustment allowance, and the boundary between the wall surface panel and the adjacent member is inconspicuous. .. Therefore, the wall panel is installed in the passenger compartment of the railway vehicle in a good-looking manner even if a sufficient adjustment allowance is secured. Further, since the end face of the wall panel is provided in an arc shape, the end face is less likely to interfere with the adjacent member even if the position is adjusted so as to be attracted to the adjacent member within the adjustment allowance.

Further, for example, even when the wall surface panel is attached obliquely to the bone member, the edge portion of the surface of the wall surface panel in contact with the bone member is hidden by the arcuate end surface. Moreover, since the end face of the wall panel has an arcuate shape, a gap is formed between the end face and the bone member, and the contour of the end face moves depending on the viewing angle and is not clear. Therefore, the inclination of the wall panel having the above configuration is less noticeable than that of the wall panel having a flat end face and the edge portion being clearly visible as a straight outline.

(2) In the configuration according to (1), the wall surface panel has a cross section U joined to the first and second decorative boards arranged in parallel and the edge portions of the first and second decorative boards. It is preferable to have a character-shaped end member.

In the above configuration, the arc-shaped end faces can be easily provided at both ends of the wall surface panel only by joining the end members having a U-shaped cross section to the first and second decorative plates.

(3) In the configuration described in (2), it is preferable that the end member is formed by extrusion processing, press molding processing, or drawing molding processing.

With the above configuration, the end member can be formed into a U-shaped cross section by one process, and a wall panel having both end faces having an arc shape can be easily and inexpensively manufactured.

(4) In the configuration according to any one of (1) to (3), the wall panel has a wall panel mounting structure in which the wall panel is attached to the bone member with the ends in the width direction abutted against each other. Is preferable.

In the wall panel mounting structure having the above configuration, the end faces of the wall panels arranged to be abutted protrude into each adjustment allowance. Therefore, the width of the gap formed between the end faces of the wall panels arranged in abutment is narrower than the width of the gap provided between the edge portions of the panel surfaces located on the bone member side in order to secure the adjustment allowance. , It looks like the wall panels are pulled together and placed. Therefore, according to the above configuration, even if a sufficient adjustment allowance is secured for each of the wall panels to be butt-arranged, the boundary between the wall panels is not conspicuous, and the wall panels can be butt-mounted in a good-looking manner.

Therefore, according to the present invention, it is possible to provide a railway vehicle that can be installed with a good-looking wall panel even if a sufficient adjustment allowance is secured.

FIG. 6 is a cross-sectional perspective view of the wall panel mounting structure shown in FIG. 6 as viewed from the outside corner side.

Hereinafter, embodiments of a railway vehicle according to the present invention will be described with reference to the drawings.

FIG. 2 is a diagram showing a wall panel mounting structure 1 according to an embodiment of the present invention in part A of FIG. Note that FIG. 2 is a view of part A in FIG. 1 viewed from the floor side (back side in the drawing), and is a mirror image of FIG. The wall panel mounting structure 1 is used to form the wall surface 112 of the machine room 110 in the railway vehicle 100 of FIG. 1, as in the prior art. The bone members 125A and 125B are installed in the structure 101 in the same manner as in the prior art. In the wall surface panel mounting structure 1, the end faces 2Ax and 2Bx at both ends of the wall surface panels 2A and 2B to be mounted on the bone member 125B in the lateral width direction are provided in an arc shape protruding outward in the lateral width direction of the wall surface panels 2A and 2B, respectively. It is characterized by being. Since the wall surface panels 2A and 2B are provided in the same manner except for the width, the wall surface panel 2A will be described here, and the description of the wall surface panel 2B will be omitted.

The wall surface panel 2A has a square plate shape, and the vertical width is provided according to the height of the vehicle interior 102, and the horizontal width is provided according to the vehicle width direction dimension of the machine room 110. The wall surface panel 2A has, for example, a sandwich structure in which the first decorative plate 21 is adhered to one surface of the core material 23 and the second decorative plate 22 is adhered to the other surface of the core material 23. At each end of the wall surface panel 2A in the lateral width direction, an end member 24 is erected between the first decorative plate 21 and the second decorative plate 22.

The end member 24 has a U-shaped cross section in which a rectangular metal plate having the same vertical width as the first and second decorative plates 21 and 22 is opened along the longitudinal direction by extrusion molding, press molding, or withdrawal molding. It is molded into a shape. The end member 24 is provided so that a pair of extending portions 24b and 24c extend substantially in parallel from both ends of the end face forming portion 24a provided in a semicircular shape. In such an end member 24, the inner side surface of one extending portion 24b is brought into contact with the outer surface of the first decorative plate 21, and the inner side surface of the other extending portion 24c is brought into contact with the outer surface of the second decorative plate 22. By adhering the respective contact surfaces, they are joined to the first and second decorative plates 21 and 22. The end member 24 is arranged so that the semicircular end face forming portion 24a projects outward from the edge portions 21a, 22a of the first and second decorative plates 21 and 22 in the lateral width direction of the wall surface panel 2A. An arcuate end face 2Ax is formed on the surface. Therefore, the wall surface panel 2A can easily form the arc-shaped end face 2Ax only by adhering the end member 24 to the first and second decorative plates 21 and 22. Further, since the end member 24 is a separate member from the first and second decorative plates 21 and 22, it is easy to form the end member 24 into a U-shaped cross section.

In the present embodiment, in order to reduce the weight of the wall surface panel 2A, the core material 23 is made of a foam material, and the first and second decorative plates 21 and 22 and the end member 24 are made of an aluminum material. Further, in the present embodiment, the thickness of the core material 23 is about 10 mm to about 20 mm, the thickness of the first and second decorative plates 21 and 22 and the end member 24 is about 2 mm, and the bone member 125A. , The thickness of the wall panel 2A of the portion attached to 125B is set to about 2 mm. Therefore, the wall surface panel 2A is easy for the operator to grasp and handle both ends in the width direction. Further, the bone members 125A, 125B and the screw seats 123A, 123B, 123C of the present embodiment are made of, for example, an aluminum material in order to reduce the weight of the vehicle.

The wall surface panel 2A is positioned with respect to the bone members 125A and 125B, and both ends in the lateral width direction are attached to the bone members 125A and 125B by mounting screws 122C and 122A, respectively. Further, the wall surface panel 2B is positioned with respect to the bone member 125B, and the end portion is attached to the bone member 125B by the mounting screw 122B. A plurality of mounting screws 122A to 122C are arranged in the height direction of the wall surface panels 2A and 2B. As a result, in the wall panel mounting structure 1, the wall panels 2A and 2B are arranged in a state where the end faces 2Ax and 2Bx are butted against each other, and the machine room 110 is partitioned from the operation room 104. A gap S is provided between the edge portion 21a of the wall surface panel 2A and the edge portion 21a of the wall surface panel 2B, and an adjustment allowance X1 for absorbing an attachment error between the wall surface panels 2A and 2B and the bone member 125B. , X2 are provided.

The wall surface panel mounting structure 1 of the present embodiment is provided in an arc shape in which the end faces 2Ax and 2Bx of the wall surface panels 2A and 2B project outward in the width direction. Therefore, for example, the width W1 of the gap S provided to secure the adjustment allowances X1 and X2 (see FIG. 2) is the same as the width W1y of the gap S provided to secure the adjustment allowances X1y and X2y shown in FIG. Then, the width W11 of the gap Sx formed between the end faces 2Ax and 2Bx when viewed from the protruding corner side is the width W1 of the gap S (see FIG. 2) and the width W1y of the gap Sy (see FIG. 2). 6) It becomes narrower. Therefore, in the wall panel mounting structure 1 shown in FIG. 2, even if the adjustment allowances X1 and X2 are the same as the adjustment allowances X1y and X2y of the conventional wall panel mounting structure 120 shown in FIG. 6, the wall surface panels 2A and 2B shown in FIG. 2 are used. Since it seems that the wall panels 121A and 121B shown in FIG. 6 are arranged closer to each other and the boundary between the wall panels 2A and 2B is inconspicuous, the wall panels 2A and 2B can be installed in a good-looking manner.

Further, for example, the width W11 of the gap Sx formed between the end faces 2Ax and 2Bx of the wall surface panels 2A and 2B shown in FIG. 2 is made equal to the width W1y of the gap Sy of the conventional wall surface panel mounting structure 120 shown in FIG. In this case, the width W1 of the gap S formed between the edge portion 21a of the wall surface panel 2A shown in FIG. 2 and the edge portion 21a of the wall surface panel 2B is the edge portion of the wall surface panel 121A shown in FIG. The width W1y of the gap Sy formed between the portion 1211a and the edge portion 1211a of the wall surface panel 121B is larger than the width W1y of the gap S, and the adjustment margins X1 and X2 shown in FIG. 2 are larger than the adjustment margins X1y and X2 shown in FIG. Therefore, the wall panel mounting structure 1 shown in FIG. 2 is shown in FIG. 2 while making the appearance of the butted portions of the wall panels 2A and 2B seen from the protruding corner side similar to those of the wall panel mounting structure 120 shown in FIG. Since the adjustment allowances X1 and X2 can be secured larger than the adjustment allowances X1y and X2y shown in FIG. 6, the wall surface panels 2A and 2B can be installed with good appearance while sufficiently securing the adjustment allowances X1 and X2.

In particular, when each end member 24 has the same color as the bone member 125B or a color (darker color) slightly lower than that of the bone member 125B, the wall surface panels 2A and 2B and the bone member 125B can be seen integrally. Therefore, the boundary between the wall surface panels 2A and 2B becomes inconspicuous, and the wall surface panels 2A and 2B can be arranged so as to look good.

As described above, as shown in FIG. 2, the railway vehicle 100 of the present embodiment has a structure 101, a bone member 125B installed in the structure 101, and a wall panel attached to the bone member 125B to partition the vehicle interior 102. In the railway vehicle 100 provided with 2A (2B) and an adjustment allowance X1 (X2) for absorbing the mounting error between the bone member 125B and the wall panel 2A (2B), the wall panel 2A (2B) has a width. The end faces 2Ax (2Bx) at both ends of the direction are provided in an arc shape protruding outward in the width direction.

The railroad vehicle 100 is a large structure in which the structure 101 and the internal frame are welded, and the position of the bone member 125B installed in the structure 101 may differ from the design due to welding distortion or the like. In this case, the wall surface panel 2A (2B) is positioned with respect to the bone members 125A and 125B (125B) within the range of the adjustment allowance X1 (X2), and is attached to the bone members 125A and 125B. Specifically, before the wall panels 2A and 2B are installed, the bone members 125A and 125B and the screw seats 123A, 123B and 123C are not formed with tap holes 1253, 1251, 1252, 1231, 1232, 1233. In this state, the operator, for example, moves the wall surface panel 2A (2B) in the horizontal direction to adjust the position with respect to the bone members 125A and 125B (125B). After the position of the wall panel 2A (2B) is determined, the operator can adjust the positions of the insertion holes 2A2 and 2A1 (2B1) of the wall panel 2A (2B) to the bone members 125A and 125B and the screw seats 123C and 123A (123B). Is tapped to form tap holes 1253, 1251, 1233, 1231 (1252, 1232), respectively. After that, the operator fastens the mounting screws 122C and 122A (122B) inserted into the insertion holes 2A2 and 2A1 (2B1) of the wall surface panel 2A (2B) to the tap holes 1253, 1233 and 1251, 1231 (1252, 1232), respectively. Then, the wall panel 2A (2B) is attached to the bone members 125A and 125B (125B). As a result, the mounting error between the wall surface panel 2A (2B) and the bone members 125A and 125B (125B) is absorbed. In this case, the end surface 2Ax (2Bx) of the wall surface panel 2A (2B) is provided in an arc shape protruding outward in the width direction, and the end of the first decorative plate 21 (an example of the panel surface) located on the bone member 125B side. The width W11 of the gap Sx formed between the end surface 2Ax (2Bx) of the wall surface panel 2A (2B) and the adjacent wall surface panel 2B (2A) because it protrudes from the edge portion 21a toward the adjustment allowance X1 (X2) is defined as the width W11. The width W1 of the gap S provided between the wall surface panel 2A (2B)) and the adjacent wall surface panel 2B (2A) to form the adjustment allowance X1 (X2) is smaller than the width W1, and the boundary between the wall surface panels 2A and 2B becomes smaller. Inconspicuous. Therefore, the wall panel 2A (2B) is installed in the passenger compartment 102 of the railway vehicle 100 in a good-looking manner even if the adjustment allowance X1 (X2) is sufficiently secured.

Further, in the wall surface panel 2A (2B), the end face 2Ax (2Bx) is formed in an arc shape, and the thickness of the end face 2Ax (2Bx) portion becomes thinner toward the outside in the width direction. Therefore, the end surface 2Ax (2Bx) of the wall surface panel 2A (2B) protrudes outward from the edge portion 21a of the first decorative plate 21 (an example of the panel surface) located on the bone member 125B side, and the adjustment allowance X1 Even if it is arranged in (X2), it does not interfere with the adjacent wall surface panel 2B and does not interfere with the mounting error absorbing work.

Further, for example, when the bone member 125A or the wall surface panel 2A is installed with reference to the opening 101a, if the opening 101a is installed at an angle, the bone member 125A is arranged at an angle following the opening 101a. Further, the wall surface panel 2A is tilted and arranged in accordance with the bone member 125A. In this case, as shown in FIG. 3, when the wall surface panel 2B is abutted against the wall surface panel 2A and attached to the bone member 125B, the edge portion 21a of the wall surface panel 2A is oblique with respect to the edge portion 21a of the wall surface panel 2B. Therefore, there is a difference between the upper width W1a and the lower width W1b of the gap S for providing the adjustment allowance X1 (see FIG. 2). However, in the wall surface panel 2A, the edge portion 21a of the first decorative plate 21 is hidden by the end face 2Ax (end face forming portion 24a). Moreover, since the end surface 2Ax of the wall surface panel 2A has an arcuate shape, a gap is formed between the end surface 2Ax and the bone member 125B, and the end surface 2Ax appears as a deep surface. Therefore, the contour of the end face 2Ax moves depending on the viewing angle and is not clear. Therefore, the inclination of the wall surface panel 2A shown in FIG. 2 is less noticeable than that of the wall surface panel 121A in which the end surface 1213 shown in FIG. 8 is flat and the edge portion 1211a clearly appears as a straight line.

Here, in the wall panel 2B as well, the contour of the end face 2Bx provided in an arc shape is not clear. Therefore, as shown in FIG. 3, even if there is a difference between the upper gap W11a and the lower gap W11b of the gap Sx formed between the end faces 2Ax and 2Bx, the difference is difficult to understand. Therefore, the wall surface panels 2A and 2B can be installed so as to look good even when the wall surface panel 2A is tilted and attached to the bone member 125B.

Further, in the railcar 100 of the present embodiment, the wall surface panels 2A (2B) are arranged in parallel with the first and second decorative plates 21 and 22, and the edge portions of the first and second decorative plates 21 and 22. Since the end member 24 having a U-shaped cross section is adhered to the 21a and 22a, the wall panel 2A (2B) is simply joined to the first and second decorative plates 21 and 22 by joining the end member 24 having a U-shaped cross section. ), The arcuate end faces 2Ax (2Bx) can be easily provided at both ends.

Further, in the railroad vehicle 100 of the present embodiment, since the end member 24 is formed by extrusion processing, press molding processing, or drawer molding processing, the end member 24 has a U-shaped cross section in one processing. It is possible to easily and inexpensively manufacture a wall surface panel 2A (2B) in which the end faces 2Ax (2Bx) at both ends are formed into an arc shape.

Further, the railroad vehicle 100 of the present embodiment has a wall surface panel mounting structure 1 in which the wall surface panels 2A and 2B are attached to the bone member 125B in a state where the arc-shaped end faces 2Ax and 2Bx are butted against each other. In the wall surface panel mounting structure 1, the end faces 2Ax and 2Bx of the wall surface panels 2A and 2B that are butt-arranged project to the adjustment allowances X1 and X2, respectively. Therefore, the width W11 of the gap Sx formed between the end faces 2Ax and 2Bx of the wall surface panels 2A and 2B arranged abutting against each other is the first decorative plate 21 located on the bone member 125B side in order to secure the adjustment margins X1 and X2. It is narrower than the width W1 of the gap S provided between the edge portions 21a of (an example of the panel surface), and it seems that the wall surface panels 2A and 2B are attracted and arranged. Therefore, according to the railroad vehicle 100 of the present embodiment, even if the adjustment allowances X1 and X2 are sufficiently secured for the wall panels 2A and 2B to be butt-arranged, the boundary between the wall panels 2A and 2B is inconspicuous, and the wall panels 2A and 2B can be installed by matching them with each other.

Therefore, according to the present embodiment, it is possible to provide the railroad vehicle 100 that can be installed with good-looking wall panels 2A and 2B even if the adjustment allowances X1 and X2 are sufficiently secured.

The present invention is not limited to the above embodiment, and various applications are possible.

For example, as in the wall panel mounting structure 1A shown in FIG. 4, the screw seats 123A and 123B may be fixed to the outer surface of the bone member 125Bx having an L-shaped cross section by welding or rivets. In this case, after adjusting the positions of the wall surface panels 2A and 2B inside the bone member 125Bx within the range of the adjustment allowances X1 and X2, tap holes 1251, 1252, 1231, 1232 are formed in the bone member 125Bx and the screw seats 123A and 123B. Then, by fastening the mounting screws 122A and 122B inserted into the insertion holes 2A1 and 2B1 of the wall surface panels 2A and 2B to the tap holes 1251, 1252, 1231, 1232, the wall surface panels 2A and 2B are attached to the bone member 125Bx. You may. Also in this case, the wall surface panels 2A and 2B are provided in an arc shape in which the end face forming portions 24a project outward in the width direction and project into the adjustment margins X1 and X2. When viewed, the width W11 of the gap Sx between the end faces 2Ax and 2Bx is narrower than the width W1 of the gap S between the edge portions 22a and 22a. Therefore, even with the wall panel mounting structure 1A shown in FIG. 4, as with the wall panel mounting structure 1 shown in FIG. 2, even if the adjustment allowances X1 and X2 are sufficiently secured, the wall panels 2A and 2B can be installed so as to look good against each other. ..

For example, as in the wall panel mounting structure 1B shown in FIG. 5, a flat surface may be provided at the tip ends of the end faces 6Ax and 6Bx of the wall panels 6A and 6B. That is, for example, in the end member 61, the end surface forming portion 61d is connected so that the flat tip surface 61a is connected to the extending portion 24b via the curved surface portion 61b and is connected to the extending portion 24c via the curved surface portion 61c. It may be provided. In this case, for example, the wall surface panels 6A and 6B have a curved surface portion 61b from the area of the tip surface 61a so that the end faces 6Ax and 6Bx do not interfere when the positions of the wall surface panels 6A and 6B are adjusted within the range of the adjustment allowances X1 and X2. It is preferable to provide the tip surface 61a so that the combined area of, 61c is larger. According to this, in the wall surface panels 6A and 6B, the overall cross-sectional shape of the end faces 6Ax and 6Bx is arcuate, and the same effect as that of the above embodiment can be obtained.

For example, the wall surface panels 2A and 2B do not necessarily have to be arranged so as to be butted at right angles, and may be arranged so as to be butted at an acute angle or an obtuse angle.

For example, in the above embodiment, the core material 23 is made of a foaming material, but it may be made of a paper honeycomb or the like. Further, the first and second decorative plates 21 and 22 and the end member 24 may be made of a melamine resin plate or the like instead of a metal plate such as an aluminum material. Further, for example, the wall surface panel is not limited to a structure composed of a plurality of members such as a sandwich structure, and may be formed of a single plate.

For example, the wall surface panels 2A and 2B may be joined to the bone members 125A and 125B with a hook-and-loop fastener or the like.

For example, the bone member 125B may be formed with a horizontally long elongated hole or a round hole having a diameter larger than that of the leg of the mounting screw 122A at a position corresponding to the insertion hole 2A1 of the wall surface panel 2A. In this case, after adjusting the position of the wall surface panel 2A with respect to the bone member 125B, the operator forms a tap hole 1231 in the screw seat 123A in accordance with the position of the insertion hole 2A1 of the wall surface panel 2A, and attaches the mounting screw 122A to the wall surface. The wall surface panel 2A is attached to the bone member 125B by inserting it through the insertion hole 2A1 of the panel 2A into the elongated hole or the round hole of the bone member 125B and fastening it to the tap hole 1231 of the screw seat 123A.

For example, instead of the screw seats 123A, 123B, 123C, nuts separate from the bone members 125A, 125B may be used. In this case, the bone members 125A and 125B are formed with holes for inserting the mounting screws 122C, 122A and 122B in the horizontal direction, or have a round shape having a larger diameter than the legs of the mounting screws 122C, 122A and 122C. It is preferable that the positions of the wall surface panels 2A and 2B can be adjusted within the range of the adjustment allowances X1 and X2 by forming the wall panels 2A and 2B.

For example, steel materials may be used for the bone members 125A and 125B and the screw seats 123A, 123B and 123C.
