Description of the Related Art In recent years, railway vehicles have tended to become faster and faster in order to shorten the time required to reach a destination and increase the amount of transportation. In that case, it is necessary to reduce the weight of the vehicle in consideration of the influence on the track. On the other hand, when consideration is given to riding comfort, it is necessary to increase the rigidity, which is a contradictory factor. An example of such a vehicle body of a railway vehicle is disclosed in, for example, JP-A-2-290771.
Publication. In this vehicle body structure, a floor member is configured by arranging a plurality of light alloy extruded members in the vehicle body width direction. Further, a side beam is disposed on both sides of the vehicle body in the vehicle width direction in a longitudinal direction of the vehicle body, a cross beam disposed between the side beams and having an end attached to the side beam, and provided on an upper surface side of the cross beam. And a floor member having a curved surface having at least one or more radii of curvature in the width direction of the vehicle body. Further, as a vehicle body structure using a laminated panel as an airtight wall member for maintaining the airtightness of the vehicle body, for example, JP-A-3-90468 is cited.

程度となっている。The cross beam 2c is formed in the same shape as the cross beam 2a, and is a member for transmitting the longitudinal force from the coupler acting on the underframe to the side beam 1 via the center beams 4a and 4b described later. The bolster 4 is installed between the side beams 1 so as to be parallel to the cross beam 2 a, and an end is joined to the side beam 1. The end beams 5 are also arranged in parallel to the cross beams 2a similarly to the bolster beams 4, and the ends of the two side beams 1 are joined. The center beam 4a is installed in parallel to the side beam 1 with an interval for installing a coupler between the bolster beam 4 and the end beam 5, and the ends are the end beam 5 and the bolster beam 4. Is joined to. The center beam 4b is provided between the bolster beam 4 and the cross beam 2c.
They are installed at predetermined intervals in parallel to the side beams 1 as in the case of a. The end of the center beam 4b is joined to the bolster beam 4 and the cross beam 2c. The installation position of the bolster 4 is the center position in the front-rear direction of the bogie supporting the vehicle body, and the height of the underframe itself needs to be as short as possible in the vicinity of the pillow 4 on the underframe due to the relationship with the bogie. There is. Therefore, the cross beam 2 installed near the bolster 4
b has a substantially L-shape as a whole, and has a height dimension shorter than that of the cross beam 2a. The cross beam 2b is also made of an extruded member made of light alloy similarly to the cross beam 2a, and the floor support 6 and the floor support 7 are integrally formed at the upper part. Further, the horizontal portion at the lower portion of the cross beam 2b is formed to have a necessary width to fix a support metal for supporting the pipe wiring, which is provided at a minimum necessary at the installation position of the underframe. The cross beam 2b is installed between the cross beam 4 and the cross beam 2a closest to the cross beam 4. The floorboard 3
Are disposed so as to cover a portion surrounded by the side beam 1 on both sides of the underframe or the cross beam 2a or the cross beam 2a and the cross beam 2b, and the two face plates 3a, 3b, 3
It is constituted by a laminated panel composed of a core material 3c provided between a and 3b and an edge material 13 provided between the two face plates and on the outer periphery of the floor plate itself. In this laminated panel, the face plates 3a, 3b, the core material 3c, and the edge material 13 are made of a light alloy, and each is joined by brazing. The edge member 13 is a light alloy extruded member having a U-shaped cross section. The periphery of the floor plate 3 is mounted on the floor supports 6 and 7 of the side beams 1 or the cross beams 2a and 2b.
The length of the protruding portion of the edge member 13 is different between the upper surface side and the lower surface side of the underframe of the floor plate 3. That is, the upper surface of the floor plate 3 is longer than the lower surface. The difference between the lengths of the projecting portions of the edge members 13 is about half of the difference between the projecting dimensions of the floor supports 6 and 7.

a, 2b, the beam 4, the end beam 5, and the center beams 4a, 4b are assembled and welded. Thereafter, the underframe is manufactured by placing the floor plate 3 and performing welding. The floor plate 3 has a structure in which the length of the protruding portion of the edge member 13 is longer on the upper surface side of the underframe than on the lower surface side, so that it is easy to mount on the manufacturing. Therefore, the manufacturing operation can be facilitated.

The cross beam 2a and each of the edge members 13 are welded once at the butt portion by airtight sealing. At this time, the gap between the butting portions on the upper portion of the edge member 13 is smaller than the width of the floor support 7. Edge material 13
Is mounted on the floor support 6 and is tap-welded to the cross beam 2a at an end of the floor support 6. The floorboard 3 and the cross beam 2a are edged materials 13.
Through welding at two points, an upper portion and a lower portion. Therefore, the cross beam 2a and the edge member 13 become an integral strength member in a combined state. Therefore, a strength member, for example, a cross beam 2 that is arranged to be drawn through in the width direction of the underframe.
The substantial section modulus of a can be increased. As a result, the rigidity of the underframe can be improved. When considering the optimal design of the underframe, the weight of the strength member in the width direction can be made lighter and smaller than the conventional one. Further, in selecting a laminated panel to be used as a floorboard, it is possible to select a thinner and lighter panel than in the past because the strength in the width direction can be improved. Further, when used in a conventional structure, an improvement in strength can be expected.

う問題点を解決出来る。The vertical concentrated load applied to the lower portion of the cross beam 2a, that is, the equipment load, is transmitted to the floor panel 3 as a distributed load via the cross beam 2a and the edge member 13. In general, the laminated panel constituting the floor panel 3 has characteristics that are weak against a concentrated load and strong against a distributed load. When viewed as a whole underframe, the load point for the concentrated load should be joined to the upper and lower surfaces of the floor plate 3 via the floor supports 6 and 7 and set at the position of the cross beam 2a forming an integral strength member. Thus, the problem of concentration of the load on the laminated panel can be solved.

a, it is transmitted as moment to the floor plate 3 via the edge material 13. In this case, since the cross beam 2a and the edge member 13 are combined to form an integral strength member that is drawn in the width direction, the center of rotation is near the neutral axis of the floor plate 3. Therefore, distortion applied to the face plates 3a and 3b of the laminated panel constituting the floor plate 3 can be reduced.

信頼性を向上させる事ができる。Further, in the welded structure of the butted portion on the upper portion of the facing edge member 13 of the adjacent floor plate 3, the floor back 7 is pressed against the back side of the butted portion. Therefore, the floor support 7 serves as a back plate in butt welding. Therefore, the reliability of welding at the upper part of the edge member 13 can be improved.

Same as the cross beam 2a. Therefore, as a strength member in the width direction of the underframe, it can contribute to the improvement of the section modulus and the rigidity of the entire underframe, and the same effect can be expected in transmitting the force applied to the cross beam 2b. The same effect can be obtained for the reliability of welding.

構成とする必要がある。By the way, when the laminated panel is used as the floor panel 3, the floor panel 3 is installed on the upper surface of the underframe.
Out-of-plane rigidity of the entire underframe is improved. For this reason, stress concentration tends to occur easily at the joint between the side structure continuously formed on the underframe, that is, the portion forming the side surface of the vehicle body and the side beam of the underframe. Therefore, the member on the side structure side joined to the upper part of the side beam, that is, the long base 1a is formed into a cross-sectional shape and a plate thickness having a rigidity approximately intermediate between the bending rigidity of the underframe and the in-plane bending rigidity of the side structure. It is necessary to select. That is, it is necessary to adopt a configuration in which an extreme change in rigidity does not occur between the underframe and the side structure.

As a result, it is possible to provide a lightweight and highly rigid body frame.
