BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows an example of installing an interior panel for a railway vehicle according to an embodiment of the present invention on a railway vehicle. It is a longitudinal cross-sectional view of the longitudinal direction of the vehicle body in the vicinity portion.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. Here, parts that are the same as or equivalent to those of the conventional technique are denoted by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 1, an interior panel 10 for a railway vehicle according to an embodiment of the present invention includes a decorative panel 12 and a tension member 14, and the decorative panel 12 and the tension member 14 are integrally fixed to each other. As a flat laminate.
The decorative panel 12 is made of a material having excellent functions required for an interior panel of a railway vehicle, such as durability and fire resistance, and is exposed to the interior of the vehicle as a wall surface or a ceiling surface. It is a panel member that has been surface-treated and configured so as to have it. As an example, an aluminum alloy, a heat-resistant fiber, and a panel made of any of these materials and coated with a heat-resistant coating material may be used. On the other hand, the tension member 14 is also made of a material having excellent durability and fire resistance, but since it is not exposed in the passenger compartment, it is not necessary to consider the texture. As an example of the material used for the tension member 14, an aluminum alloy, a stainless alloy, a heat resistant fiber, or the like is used.
Further, in the illustrated example, the tension member 14 also has a panel shape like the decorative panel 12, and the external shape of the decorative panel 12 and the external shape of the tension member 14 are the same. Further, when the tension member 14 is viewed in a plan view, a window-shaped cutout 14a is formed. Therefore, the non-contact portion 12a with respect to the tension member 14 is formed in a part of the decorative panel 12 excluding the member end, specifically, a portion corresponding to the cutout portion 14a of the tension member 14.

The decorative panel 12 has a sectional shape that is curved in a bow shape as a whole in the state before being fixed alone, that is, before being fixed integrally with the tension member 14 (see FIG. 2C). As shown in FIG. 1, when the decorative panel 12 has a rectangular shape in a plan view, such as when the vertical and horizontal dimensions are different, the cross-sectional shape curved in a bow shape is parallel to the longitudinal direction. It is desirable that the cross-sectional shape be configured to curve in an arc shape. This is because the deformation in the longitudinal direction is more likely to occur than the deformation in the lateral direction, and therefore the above-mentioned characteristics are given to the cross-sectional shape in the longitudinal direction to more effectively obtain the action and effect described later. In addition, the decorative panel 12 is configured to be curved in an arc shape as "whole" even if the decorative panel 12 includes a partial shape change portion such as a case where a decorative uneven shape is formed. Has been done.

On the other hand, the tension member 14 has a linear sectional shape as a whole in the state before being fixed alone, that is, before being fixed integrally with the decorative panel 12. As shown in FIG. 1, the linear cross-sectional shape includes a partial shape-changed portion such as the tension member 14 having a panel shape and a window-shaped cutout 14a formed therein. Not only when the tension member 14 has a frame shape along the outer shape of the decorative panel 12 or when a plurality of rod-shaped members are combined, the cross-sectional shape is “ The "whole" means that it is linearly configured. Further, naturally, the case where the tension member 14 has a panel shape and is a simple plate shape without the notch 14a on the window is also included.

Further, the tension member 14 is strong enough to allow the railcar interior panel 10 that is a laminated body to form a flat laminated body while being fixed integrally with the decorative panel 12. That is, the strength of the tension member 14 is configured to exceed the strength of the decorative panel 12. For example, a high-strength material is used for the tension member 14, such as an aluminum alloy for the decorative panel 12 and a stainless alloy for the tension member 14. When both the decorative panel 12 and the tension member 14 are made of aluminum alloy, a thickness larger than that of the decorative panel 12 is ensured so that the tension member 14 has a necessary strength.

Here, a manufacturing procedure of the interior panel 10 for a railway vehicle is illustrated in FIG.
First, as shown in FIG. 2(a), a decorative panel 12 which is flat as a whole is prepared, and is plastically deformed as shown in FIG. 2(b) so that its cross-sectional shape becomes an arc shape as a whole. Bend to. When a metal material such as an aluminum alloy is used for the decorative panel 12, roll molding or the like is used as shown in FIG. When a resin material such as heat-resistant fiber is used for the decorative panel 12, it is hot-press molded or preliminarily molded so that its cross-sectional shape becomes a bow shape as a whole.

Subsequently, as an example, as shown in FIG. 2C, the decorative panel 12 having a bow-shaped cross section and the tension member 14 having a linear cross section are overlapped with each other to press the press machine 20. And the press machine 20 applies a pressure in a direction in which the decorative panel 12 and the tension member 14 are in close contact with each other. As a result, as shown in FIG. 2D, the member end of the tension member 14 is brought into close contact with the convex surface side of the decorative panel 12 having a bow-shaped cross section as a whole. In the example of FIG. 2C, since the adhesive 16 is applied in advance to the member end of the decorative panel 12 before pressing, the member ends of the decorative panel 12 and the tension member 14 are fixed by the adhesive 16. Then, as shown in FIG. 2(g), the decorative panel 12 and the tension member 14 are integrally fixed, and the railway vehicle interior panel 10 is configured as a flat laminate as a whole.

As another example, as shown in FIG. 2(e), a detachable bracket 22 is attached to the member end of the decorative panel 12 having a bow-shaped cross section as a whole, and the brackets 22 are turned around. By connecting the wires via a pulling tool such as 24 and shrinking the turnbuckle 24, an external force is applied to the member end of the decorative panel 12 in a direction in which the cross-sectional shape is straightened as a whole. Then, as shown in FIG. 2( f ), the member end of the tension member 14 is brought into close contact with the decorative panel 12 in a state where the decorative panel 12 is straightened so that the cross-sectional shape is linear as a whole. In the example of FIG. 2F, since the adhesive 16 is applied to the member end of the tension member 14 in advance, the member end of the tension member 14 is fixed to the decorative panel 12 by the adhesive 16. As shown in FIG. 2(g), the decorative panel 12 and the tension member 14 are integrally fixed, and the railway vehicle interior panel 10 is configured as a flat laminate as a whole. Although the decorative panel 12 is larger than the tension member 14 in the example of FIG. 2(d), a laminated body having such a dimensional difference may be formed, as shown in FIG. 2(g). As described above, a laminated body in which the outer shape of the decorative panel 12 and the outer shape of the tension member 14 match each other may be configured.

In any of the examples, the decorative panel 12 that is flat as a whole is plastically deformed (FIG. 2A) and is curved so that the cross-sectional shape becomes an arc shape as a whole (FIG. 2B), and then the The member end of the tension member is brought into close contact with the decorative panel in a state where it is elastically deformed so that the cross-sectional shape becomes linear as a whole (FIGS. 2D and 2F). When a resin material such as heat-resistant fiber is used for the decorative panel 12, it is molded in advance so that its cross-sectional shape becomes an arc shape as a whole, and the plastic deformation step of FIGS. 2A and 2B is omitted. Good.
Further, for fixing the outer shape of the decorative panel 12 and the tension member 14, not only the adhesive 16, but also a joining member such as a bolt or a rivet may be used, or the two may be joined by welding. In this case, when the press machine 20 is used as shown in FIGS. 2C and 2D, the shape is set so that the member ends of the decorative panel 12 and the tension member 14 are exposed outside the press die. In the pressurized state, the bonding margin of the decorative panel 12 and the tension member 14 is exposed to the outside of the press die, and the above-described bonding work can be performed.

FIG. 3 shows a partial cross-sectional view of a railway vehicle 30 that employs the railway vehicle interior panel 10 according to the embodiment of the present invention. In FIG. 3, the railway vehicle interior panel 10 is shown in gray scale. As described above, the railroad vehicle interior panel 10 is used as an interior panel that constitutes various wall surfaces exposed to the interior, such as the cabin 32 of the railcar 30, the ceiling of the vehicle end deck 34, the wall surface, and the luggage rack. .. Further, in consideration of easiness of manufacturing and workability at the time of attachment to the railway vehicle 30, a plurality of appropriately divided interior panels 10 for railway vehicles are combined and installed in a wide range. Further, although not shown, it can also be used as a floor material.
