Description

TECHNICAL FIELD The present invention relates to a side structure structure of a railway vehicle.

[Conventional technology]

Conventionally, the side structure of a railroad vehicle has been based on the actual Japanese Utility Model Publication No.
As described in No. 6, in the profile of the waist plate and the curtain plate,
Thickening the plate thickness only at the ends that make up the window frame to reduce stress concentration at the corners of the window, and by welding the studs between windows of different members at locations where stress concentration is avoided. Was becoming.

[Problems to be Solved by the Invention]

When the above-mentioned conventional technique is applied to a railway vehicle having an entrance / exit portion only at the vehicle end portion such as a high-speed vehicle, a body height of a member different from the waist plate portion and the curtain plate portion is provided between the waist plate portion and the curtain plate portion. It is necessary to form studs in the vertical direction, and in order to make the rigidity of the car body practically sufficient, side pillars in the car body height direction are formed as separate members on the waist plate and the curtain plate, respectively. It is also necessary to combine the side pillars together. As described above, the above-mentioned related art does not consider reduction of the number of parts of the sounding member in the vehicle body height direction of the railway vehicle in which the input / output is only at the vehicle end like a high-speed vehicle, and the welding workability is good. There was a problem in making the rail car structure.

An object of the present invention is to provide a structure having sufficient strength at low cost.

[Means for Solving the Problems]

The present invention provides a side structure structure for a railway vehicle having a plurality of windows, wherein the side structure has a required number of first shape members having windows opened at predetermined intervals along the longitudinal direction of the vehicle body. A second shape member joined to the upper and lower parts of the first shape member, and a side pillar arranged between the windows and connected to each of the first shape member and the second shape member; The first frame is integrally provided with a first bone member on the inner surface side above the upper end of the window and below the lower end thereof, respectively, and
Is integrally provided on the inner surface side with a second bone member having a height lower than that of the first bone member, and the height of the second bone member is the first bone member excluding the first bone member. The height is the same as the height of the inner surface side of the first shape member, and the height is based on the outer surface side of each of the first shape member and the second shape member, and the first bone member Cut out a portion intersecting with the side pillar so as to have the same height as the second bone member, and the side pillar is coupled to the inner surface side of the second bone member and the first frame member. Then, the side structure is configured.

[Work]

According to this, since the first bone members at the upper and lower portions of the window are notched and the side pillars are not notched, the out-of-plane bending configuration in the vertical direction can be sufficiently secured. In addition, not all the first bone members are cut out, but the first bone members are cut out so as to be in the same position as the height position of the second bone member. Therefore, the strength of the upper and lower parts of the window can be sufficiently secured.

Further, since the first shape member, the second shape member, and the side pillars are connected at a position away from the outer surface side of the second bone member or the like, distortion during welding does not easily appear on the outer surface side. is there.

Therefore, a lightweight side structure can be provided at low cost.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a perspective sectional view of a railway vehicle structure to which the present invention is applied, FIG. 2 is a sectional view of a side structure at a window opening of the railway vehicle structure, and FIG. 3 is a window and window of the railway vehicle structure. It is a sectional view of a side structure between and. Further, FIG. 4 is a plan view of a side structure of the railway vehicle structure as viewed from the inside of the vehicle. In the figure, 1 is a structure, 2, 3, 4, and 5 are large-sized frame members that are drawn in the longitudinal direction of the vehicle body. Of these, the frame member 2 is a frame member for connecting the side structure and the roof structure. Reference numeral 3 is a shape member that forms the curtain plate portion, and 4 is a shape member that forms the window portion. Reference numeral 5 is a shape member that forms the waist plate portion. 6 is a box-shaped side pillar that is arranged in the height direction of the vehicle body and has a box-shaped cross section formed by the same member from the curtain plate or eaves to the waist plate, and is joined to the upper surface of the side beam 7 of the underframe. . As is well known, the side pillars 6 are connected to members (shape members 2, 3, 4, 5) that come into contact with the side pillars. The shape members 2, 3, which are drawn in the vehicle body longitudinal direction,
Bone members 9 are integrally formed with the frame members 2, 3, 4 and 5 in the longitudinal direction of the vehicle body in 4 and 5, so that the cross-sections of the bone members 9 can be connected to the side columns 6. It is either L-type or T-type. The shape member 4 forming the window is
The curtain band 8 and the waist band 8'are integrally formed. The plate thickness of the shape member 4 is larger than that of the shape member 3 forming the curtain plate portion and the shape member 5 forming the waist plate portion. Here, since the curtain band 8 and the waist band 8'are formed so as to extend in the longitudinal direction of the vehicle body, a position where the side pillar 6 is fitted is cut out. The shape member 4 is symmetrical in the vertical direction of the window portion, and the connecting position of the shape members 4 and 4 is the central portion in the vertical direction of the window avoiding stress concentration. The window opening is formed by cutting the shape member 4 into a window shape.

In the above configuration, when the shape member 4 forming the window portion is the first shape member, the shape member 3 forming the curtain plate portions arranged above and below the shape member 4
The profile 5 forming the waist plate portion becomes the second profile. Further, when the curtain band 8 and the waist band 8'formed on the frame member 4 forming the window portion are used as the first bone members, the bones formed on the frame members 2, 3 and 5 located above and below the frame member 4 respectively. The member 9 becomes the second bone member.

With such a configuration, the plate thickness of the shape member 4 forming the window portion can be made thicker than the plate thickness of the shape member 3 forming the curtain plate portion and the shape member 5 forming the waist plate portion. The strength of the portion forming the frame can be improved without using a reinforcing material. Further, since the side pillars 6 in the vehicle body height direction can be connected to each other between the underframe and the roof structure by the same member, the number of parts can be reduced. Further, the shape members 2, 3, 4
Since the welding joints 10 and 5 can be continuously performed in all the longitudinal directions of the vehicle body, automation of the welding operation can be facilitated.

Further, since the curtain belt 8 and the waist belt 8 '(hereinafter referred to as the bone members 8 and 8') at the upper and lower portions of the window portion are not cut out and the side pillars 6 are not cut out, the strength around the window portion can be improved. A sufficient side structure can be secured and a lightweight side structure can be provided at low cost.

That is, it is the members around the window (bone members 8 and 8 ', side pillars 6) that bear the load of the window. When two members having different heights intersect, one member is cut out.
In the side structure of the vehicle, the number of side pillars is smaller than the vertical load, so that the burden on the side pillars is large. In the present invention, the side pillars 6 are not cut out, but the horizontal bone members 8 and 8'are cut out, so that sufficient out-of-plane bending rigidity in the vertical direction can be secured. Further, not all the bone members 8 and 8'are cut out so that they are located at the same position as the height position of the bone member 9, so that the bone members 8 and 8'have a corresponding height. Therefore, the strength of the upper and lower parts of the window can be sufficiently secured.

Further, since the shape members 3, 4, 5 and the side pillars 6 are connected to each other at a position away from the outer surface side of the bone member 9 or the like, distortion during welding is unlikely to appear on the outer surface side. The shape member 4 does not have a bone member, but is the same because it is thick.

Therefore, a lightweight side structure can be provided at low cost.

Next, another embodiment of the present invention will be described with reference to FIG.
FIG. 5 is a sectional view of a side structure between windows. In the figure, the thickness of the shape member 4 forming the window portion is thick only in the window even portion, and the central portion between the windows has the same thickness as the other shape members 3 and 5. Further, a bone member 9 for connecting with the side pillar 6 is integrally formed.

With such a configuration, the profile 4 of the window portion can be made lighter, and the same effect as that of the above-described embodiment can be obtained.

By the way, in each of the above-described embodiments, the structure in which the surface of each side structure is flat has been described, but the surface of each side structure can be formed into an arc surface by providing a curvature to each shape member.
That is, each shape member has a predetermined arc cross section, and by joining these on a jig, an arc surface with less distortion can be constructed. Further, it is relatively easy to form an arcuate cross section in the shape member, and it is possible to obtain a highly accurate one. From this, the appearance can be improved as compared with the conventional side structure in which the side outer plate is a thin plate and is attached to each bone member to form an arc surface.

In addition, in the above-mentioned structure, the side pillar may be curved, or the height of the bone member on the back surface of the shape member may be changed to eliminate the gap with the side pillar.

〔The invention's effect〕

According to the present invention, since the bone members in the upper and lower portions of the window are notched and the side pillars are not notched, the vertical out-of-plane bending configuration can be sufficiently secured, and the strength of the upper and lower portions of the window can be sufficiently increased. In addition, it is possible to provide a lightweight side structure that can be secured, can prevent distortion, and can be provided at low cost.
