BACKGROUND OF THE INVENTION
The present invention relates to a partition such as an inner end partition provided between a guest room and an entrance / exit (deck) in an express train of a railway vehicle, and more particularly to a method for mounting and constructing the partition.
[0002]
[Prior art]
In a railway vehicle, particularly an express vehicle, a guest room in which a stool is arranged and an entrance / exit that serves as a boarding / exiting gate for the vehicle are partitioned by an inner gable partition.
The conventional inner wife partition is attached by fixing its frame to the vehicle structure by welding or the like.
For example, FIG. 8 is a schematic longitudinal sectional view showing a conventional mounting structure of the inner end partition A, and shows a state cut along a line along the longitudinal direction of the vehicle. FIG. 9 is a perspective view showing a lower mounting structure of the inner end partition A. FIG.
[0003]
In the conventional example shown in the figure, the vehicle structure B is constituted by a shape member provided with a rib C having a substantially L shape or the like. And the inner wife partition A cuts the rib C of the structure B with a predetermined width along the width direction of the vehicle, welds the open ends of the substantially U-shaped cradle D to the cut portion, The mounting bracket E on the inner end partition A side was welded to the cradle D. Thereafter, a floor was formed by laying a rug on the upper surface of the rib of the lower structure (underframe), and an intermediate ceiling or the like was disposed below the upper structure. Since the inner strength of the inner partition cannot be maintained unless it is directly welded to the vehicle structure side, it could not be attached to the upper part of the rug or the like.
[0004]
[Problems to be solved by the invention]
However, if the inner end partition is fixed to the vehicle structure by welding or the like as in the conventional configuration, the inner end partition cannot be moved or removed. In other words, the conventional inner wife partition is completely fixed to the structure by welding or the like and is permanently fixed, so it cannot be removed or moved.
By the way, it is known that the number of passengers varies depending on the season depending on the route in the railway company. Therefore, if the inner wife partition can be moved, it is preferable that the number of seats installed in the cabin can be changed by moving the position of the seats little by little.
[0005]
In addition, in the conventional configuration, since the inner wife partition and the structure are completely fixed and connected, it is inevitable that the floor structure constructed on the upper surface of the underframe becomes discontinuous at the inner wife partition. It was. In other words, because it is necessary to firmly fix the inner wife partition to the structure by welding, it is impossible to stand the inner wife partition on the top of the rug, and the floor structure is discontinuous on the guest room side and the entrance / exit side It was to become. Therefore, the edge processing in the floor structure such as winding up of the rug end increases, and the work cost increases.
[0006]
Furthermore, in the conventional configuration in which the inner girder partition frame is attached to the structure by welding, not only preparation time for welding work is required, but also a dimensional error may occur due to distortion caused by welding.
[0007]
The present invention has been made in view of the above circumstances, and its main purpose is to be able to move and detachably attach the inner end partition etc. without welding, and to reduce the edge processing of the rug. Another object of the present invention is to provide a mounting structure such as an inner end partition of a railway vehicle that can reduce floor construction costs.
[0008]
In order to achieve the above object, the present invention is a partition for partitioning a guest room in which a stool is disposed and an entrance / exit as a vehicle entrance / exit. It is a structure that is attached to the vehicle structure, and the vehicle structure is provided with curtain rails at the lower part of the roof structure and the upper part of the frame along the longitudinal direction of the vehicle. The curtain rail is a rail that opens toward the inside of the vehicle. The rail groove is formed in a substantially T shape with the width of the opening to the inside of the vehicle being slightly narrow, and the curtain rail has a bolt and its head as a rail groove. is held, movably arranged along the rail groove, the shaft portion of the bolt towards the said opening of the rail groove on the vehicle inner side is extended is lower roof structure curtain rail and common-law wife partition Between the ceiling , Rugs are respectively provided on top of the underframe top of the curtain rail, opened notches in the ceiling and rugs in the portion corresponding to the opening of the rail groove of the curtain rail in accordance with the movable range of the common-law wife partition, The inner wife partition is attached to the vehicle structure from the portion via the shaft portion of the bolt, and the inner wife partition can be moved in the longitudinal direction of the vehicle along the curtain rail as necessary. And
