Field of the Invention The present invention relates to a side entrance / exit curtain structure of a railway vehicle, and more specifically, is connected to a long girder provided at an upper portion of a side entrance / exit portion of a railway vehicle and provided at a connecting portion with a roof at the upper portion. At the same time, the present invention relates to a side entrance / exit curtain structure of a rail vehicle having a rail mounting seat for supporting an upper rail for a side sliding door on the inner surface.

[0002]

2. Description of the Related Art This type of curtain structure above the side entrance is
It is one of the components of the side entrance / exit of a railway vehicle and is an element that maintains the strength of the entire vehicle body. Since it also serves as a support member for attaching the upper rail for hanging the side sliding door as described above, a large strength is required as a whole.

FIGS. 4 to 6 show a half of a side entrance upper curtain structure of a stainless steel railway vehicle.

In this structure, a channel-type flange b is integrally formed on the lower edge of the inner surface of the curtain strip base plate a, and channel-type vertical columns c are formed at ten positions in the longitudinal direction of the inner surface of the curtain strip base plate a. It is applied in the width direction of the curtain strip substrate a and is joined by spot welding, and a joint e for coupling with the long girder d is joined by welding to the upper end of each column c, and the long girder d and the plug are joined by this joint e. Joined by welding.

At the lower end of each vertical column c, a joint f for joining the channel type flange b of the curtain strip substrate a is joined by welding, and the joint f and the flange b are joined by welding. .

Further, a screw seat g is provided at the center of each vertical column c, and this part serves as a mounting seat for the upper rail i for suspending the side sliding door h. The side sliding door h is movably suspended on the rail i by a door roller j provided at the upper end.

[0007]

However, in the above-described conventional structure, a large number of vertical columns c are required, and the vertical columns c are connected to the girders d and the lower edge flanges b of the curtain strip substrate a by that much. A large number of joints e, f are also required, and the number of work places for joining the curtain band substrates a to each other increases. Further, since a large number of vertical columns c form a large number of transverse ridges in the longitudinal direction of the inner surface of the curtain band a, it is an obstacle to performing joining work such as spot welding while moving in the longitudinal direction.

Therefore, in the above-mentioned conventional structure, both the number of parts and man-hours are large, and moreover, the parts for connecting work with each other,
Since unevenness of the part is an obstacle and work is hard to come off and inefficiency, expensive horsetail production is prolonged. In addition, the flatness in the longitudinal direction becomes poor.

Therefore, the present invention aims to provide a side entrance / exit section curtain structure for a railway vehicle which can solve the above-mentioned conventional problems by improving each structure of reinforcement and mutual connection. To do.
