る。As a railroad vehicle travels at high speed, problems such as an increase in impact on tracks, an increase in noise generated during travel, and an increase in operating power cost occur. In order to solve these problems, it is necessary to reduce the weight of the entire railway vehicle. In order to reduce the weight, it is indispensable to reduce the weight of the structure that occupies a large specific gravity of the total weight.

増大という問題があった。In order to reduce the weight, an extruded shape member made of a light alloy is adopted, and the outer plate portion is also constituted by the extruded shape member. However, there is a technical limit in reducing the plate thickness of the extruded profile itself. Further, since the out-of-plane bending rigidity of the plate itself is lowered, it is necessary to install a large number of reinforcing materials, which causes a problem of increasing the number of manufacturing steps.

その強度と信頼性の確保の点で問題があった。On the other hand, in the aluminum honeycomb sandwich panel conventionally used as a floor board, the surface material and the core material are joined by a resin adhesive. Therefore, there is a problem in that the number of man-hours is increased as compared with the welding and joining because the joining with the skeleton member is performed by using bolts, nuts or rivets. Further, since the bending rigidity of the conventional aluminum honeycomb sandwich panel is determined by the strength of the resin adhesive, when used in a portion where a large load acts,
There was a problem in securing its strength and reliability.

する関係にあり、実現するのが困難な状況にある。By the way, it is known that when a railway vehicle travels in a tunnel at a high speed, the pressure outside the vehicle suddenly changes. In particular, large pressure fluctuations occur in a short time when vehicles rub against each other in a tunnel. In order to prevent such pressure fluctuations from propagating in the vehicle and causing passengers to feel uncomfortable, the entire structure has a confidential structure. Therefore, the load of passengers and various devices, the weight of the structure itself, and the pressure due to the pressure fluctuation outside the vehicle act on the structure. Therefore, it is necessary to improve the rigidity of the structure and the strength against a pressure load. However, there is a contradictory relationship between improving the rigidity and strength of the structure and reducing the weight, and it is difficult to achieve this.

ことにより、達成される。The object is to construct a side structure and a roof structure from a light alloy surface material, a core material, a frame material and a connecting member, and dispose the surface materials on both sides of the core material. And arranging a coupling member on the outer periphery of the core material and the surface material,
These are respectively joined by brazing to form a structure from the side structure and the roof structure, the eaves member installed in the longitudinal direction of the vehicle body, and the bone member installed in the circumferential direction of the vehicle body. This can be achieved by forming an annular shape with the same pitch.

両構体の耐圧性を向上させることができる。[Function] When a railway vehicle travels at high speed, pressure fluctuations occur outside the vehicle. Especially when the vehicles rub against each other in the tunnel, the pressure fluctuation becomes maximum. This fluctuation of the pressure outside the vehicle acts on the security wall constituting the structure. In order to withstand such a pressure fluctuation, the side outer plate member constituting the side structure of the present invention is formed of a laminated material in which a core material and a surface material are superposed and are joined by brazing. The side outer plate member has a high out-of-plane bending rigidity and can sufficiently withstand the external pressure. Therefore, according to the present invention, the pressure resistance of the railway vehicle structure can be improved.

ることができる。When the pressure fluctuation acts on the structure, pressure is also applied to the roof structure. Further, the roof structure has a large area that receives the pressure fluctuation. Therefore, the roof outer plate member constituting the roof structure of the present invention is configured by stacking the core material and the surface material and joining them by brazing. The roof outer plate member has a high out-of-plane bending rigidity and can sufficiently withstand the external pressure. Therefore, according to the present invention, the pressure resistance of the railway vehicle structure can be improved.

の公称応力を低減でき剛性向上が図れる。Further, in the side outer plate member and the roof outer plate member, since the core member and the connecting member are connected by brazing, the load is dispersed from the connecting member not only to the surface member but also to the core member. Can be transmitted. As a result, the nominal stress of each outer plate member can be reduced and the rigidity can be improved.

である。したがって、該外板部材を用いて製作される構
体は軽量なものとなる。Furthermore, each of the outer plate members is lighter than conventional materials. That is, since the surface material and the core material composed of the light alloy book plate are the main constituent materials, the material itself is lighter than the conventional rigid material, and compared with the light alloy extruded shape material. Since each plate is thin, it is lightweight. Therefore, the structure manufactured by using the outer plate member becomes lightweight.

変形を伴うことなく荷重を負担できる状態であるため、
外板部材として用いる場合に極限設計が可能となる。By the way, since the outer plate member has the surface material and the core material joined by brazing, each surface material itself has a structure in which the entire surface is joined to the core material.
Therefore, the surface material is less strained than the conventional outer plate and is always bonded to the bone member in a smooth state. This means that the surface material itself can bear the load together with the bone member without deformation.
When it is used as an outer plate member, it is possible to design it to the limit.

As a result, it is possible to reduce the weight while improving the rigidity of the structure.

That is, a plurality of the outer plate members 13a and 13b to be joined are placed on a jig having a supporting surface that matches the surface of the structure or the roof surface, and the connecting members 20 adjacent to each other are bound with the outer plate members 13a and 13b restrained. Weld and join from the inside. After that, the side pillars 9b and the rafters 10 are provided at predetermined positions on the upper surfaces of the outer plate members 13a and 13b, that is, inside the vehicle.
They are joined together by placing b and welding them while restrained. In this way, the side structure 2 or the roof structure 4

Manufacturing of each part becomes easy. The side posts 9a and 9b and the rafters 10a and 10b are formed of U-shaped members having a symmetrical cross section corresponding to the joints 21 between the blocks. This makes it possible to standardize the material, reduce the weight, and improve the rigidity.

b, 10b and the joining member 20 form a box-shaped cross section,
Strength and rigidity are improved. Further, considering the rigidity and weight reduction of the entire structure of the surface members 14 and 15, the thickness of the plate member of the surface member 14 on the inner side of the vehicle is made thinner than that on the outer side of the vehicle to reduce the weight. Further, since the outer surface surface material 15 may come into contact with other objects during manufacturing or transportation, the plate material is thicker than the inner surface.
Further, the coupling member 19 is densely pitched in the vicinity of the pillow beam, which is a high stress portion, from the viewpoint of improving the strength, and the central portion in the longitudinal direction of the vehicle body is roughened in places where it is unnecessary for strength. Due to the above matters, the outer panel member (13
a, 13b) are constructed.

When internal pressure is applied, or when a force is applied in the longitudinal direction of the vehicle, stress is increased at the corners, so it is necessary to improve strength. For this reason, the reinforcement 22 has a width B on the side beam 6 side of B = 2 × A when the width of the side pillar 9a is A and a length l of 5 × A or more improves strength without significantly increasing weight. Can be achieved.
The size relationship of the reinforcement 22 is as described above. It is said that the effective width in terms of strength is 5 to 8 times the thickness C of the web of the side pillar 9a, although the width B can be as large as possible. Since it is meaningless to have more than this, it is effective from the experience that the width B is 2 × A and the length l is 5 × A. Rafters 10a, 10b
Also performs the same processing. Further, the reinforcement 22 is joined to the joining member 25 at the lower end on the outer plate 13a side at the joining portion 21.

及び口開きがなくなる。As for the roof structure 4, as shown in FIG. 9, the portion connecting the roof structure 4 and the eaves girder 11 is configured such that the E size is longer than the F size with the eaves girder 11 side being a U-shape perpendicular to the radial direction. In this case, the end portion of the E dimension portion projects more than the end portion of the F dimension portion when viewed two-dimensionally from the roof structure side. When the roof structure 4 is lowered, the lower surface 23a of the member 23 on the roof structure 4 side comes into contact with the E dimension portion, so that the structure can be easily joined. However, this portion often becomes the inflection point of the moment when the internal pressure acts on the entire vehicle, and therefore shearing force acts. In order to support this, it was decided to make the truss structure 24 by making the shape of the connecting member 23 of the roof structure 4 not the U shape but the square shape. When the truss member 24 is inserted, the truss member 24 becomes a special lobe, the flow of force becomes smooth, and stress concentration and opening of the U-shaped portion of the member 23 and the eaves girder 11 are eliminated.

It is composed of an outer plate member having a smaller weight per unit area than a conventional structure composed of extruded shape members. It is possible to optimize the bonding between the outer plate member and the skeleton member and the reinforcing material that makes the bonding strength sufficient.
