  By the way, the piping arranged on the roof structure of the railway vehicle structure is installed on the roof structure by the holding member. The holding member has a U-shaped holding portion for holding the pipe, and holds the pipe by holding the pipe between the holding portion and the rafter member constituting the roof structure. As a method of disposing the holding member on the roof structure, generally, for example, a method of making a hole in the rafter member and screwing a fixing bolt (screw) into the hole to fix the holding member to the rafter member. It has been adopted.

  As described above, in order to arrange the holding member of the pipe on the roof structure, it is necessary to set a position for attaching the holding member (pipe), but since there are many wirings and pipes arranged on the roof structure, There were problems such as complicated handling and poor workability. In addition, the work of forming holes in the rafter member in the roof structure in which piping and wiring are complicated as described above has a problem that it takes time and effort.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a railway vehicle structure that can improve the workability of pipe installation.

  In order to solve the above problems, a railway vehicle structure according to the present invention is a railway vehicle structure including a roof structure constituted by a roof plate and a rafter member, and the rafter member is arranged in the width direction of the railway vehicle structure. A plurality of roof boards are arranged at predetermined intervals in the front-rear direction, and the roof board includes a step board having a flat surface part extending in the front-rear direction, and is defined by the flat surface part of the step board and the rafter member. The holding member which hold | maintains piping is arrange | positioned in the space to be performed.

  In this railway vehicle structure, a step board having a flat surface portion is provided on the roof plate, and a pipe holding member is disposed in a space defined by the flat surface portion of the step board and the rafter member. In this manner, the holding member can be easily installed on the roof structure by arranging the holding member in the space between the rafter member and the step board. Therefore, it is possible to improve the piping workability.

  The rafter member is curved in an arch shape so as to protrude upward when viewed from the front-rear direction, and the flat surface portion extends substantially horizontally outward from the predetermined position on the upper surface of the rafter member in the width direction.

It is made. With such a configuration, a space is favorably formed between the rafter member and the flat surface portion.

  It is preferable that the holding member is configured in an arc shape and has a locking portion for locking the pipe, and the locking portion is elastically deformable. Since the conventional holding member has a configuration in which the pipe is sandwiched between the rafter member and the U-shaped holding portion, there is a problem that it takes time to fix the pipe. In addition, since a plurality of holding members are arranged on the roof structure, it takes time and labor to make a hole in the rafter member. Furthermore, the formation of a hole in the rafter member is often performed after the rafter member is in a single item or after being assembled as a roof structure, especially when it is assembled as a roof structure. Since the generated dust enters the passenger compartment, there is a problem that cleaning is necessary and work is increased. On the other hand, in the holding member of the present invention, since the locking portion is configured to be elastically deformed, an operation of attaching the pipe to the holding member can be easily performed. Moreover, since it is the structure which latches piping, fixation with a volt | bolt becomes unnecessary and the formation of the hole for volt | bolts is also unnecessary in connection with it. Therefore, it is possible to further improve the workability of installing the pipe.

  The holding member is preferably fixed to the rafter member side. Thus, by fixing the holding member to the rafter member side, it is possible to more efficiently perform the operation of installing the pipe.

  A reinforcing member that is erected between the flat surface portion of the step board and the rafter member in the space, is fixed to the flat surface portion and the rafter member, and one end portion of the holding member and the reinforcing member are integrally formed. Is preferred. According to such a configuration, the strength of the walking board can be ensured. In addition, the number of parts can be reduced and the number of work processes can be reduced.

  It is preferable that a plurality of holding members are arranged over the entire length of the step board. According to such a structure, piping can be hold | maintained reliably.

  According to the present invention, it is possible to improve the piping workability.
