In the present embodiment, it is assumed that the platform 1 is located on the left side of the vehicle traveling in the traveling direction Y on the traveling path.

  Like the existing home, the home body 2 is a structure having, for example, a structure in which concrete plates are arranged or a reinforced concrete structure, and extends along the traveling path of the vehicle, that is, along the traveling direction Y of the vehicle. It is installed to exist. A surface of the home main body 2 facing the traveling road side of the vehicle is the side edge portion 2a.

  4 A of buffer parts have the predetermined mutual space | interval in the advancing direction Y of a vehicle, the floor slab support part 6 provided in multiple arrangement | sequence, and the several floor slab 7 laid on these floor slab support parts 6; It has.

  The floor slab support 6 extends from the side edge 2a of the home main body 2 toward the vehicle traveling path, that is, extends along the horizontal direction X orthogonal to the traveling direction Y of the vehicle. It is arranged. The floor slab support 6 supports the floor slab 7 and the crowd load on the floor slab 7, so that the base end is joined to the side edge 2 a of the home body 2 and the tip edge is the side edge of the home body 2. It protrudes substantially horizontally from the portion 2a in a direction substantially perpendicular to the traveling direction Y of the train.

  The joining method of the side edge 2a of the home body 2 and the floor slab support may be a structure in which the base end side of the floor slab support 6 is embedded in the home body 2 or may be a bolted structure. . At least, any method may be used as long as it is a fixing method that can be held when a crowd load is applied to the floor slab 7 at all times.

The floor slab support 6 is preferably made of a material having a strength lower than that of the train body.
Further, in the vertical direction Z, the floor slab support 6 has a high rigidity in the load in the vertical direction Z in order to ensure the strength to support the floor slab 7 and the crowd load of passengers on the floor slab 7. It is preferable. Furthermore, it is preferable that the floor slab support 6 is configured to be easily elastically deformed or plastically deformed in the traveling direction Y in order to reduce the impact when the vehicle collides with the buffer 4A due to an earthquake or the like.

  In order to realize such a floor slab support 6, the floor slab support 6 has a substantially flat plate shape including a plane substantially perpendicular to the traveling direction Y in the present embodiment. Further, the floor slab support 6 may have a structure in which rods (typically reinforcing bars) made of steel, aluminum or the like are assembled in a flat truss shape (two-dimensional truss shape) in addition to the flat plate shape. Good.

  The floor slab 7 includes a plurality of (four in the present embodiment) floor slab pieces 8 having a rectangular shape in plan view with the traveling direction Y as the longitudinal direction, in the horizontal direction X orthogonal to the traveling direction Y, that is, the home It is set as the structure laid one by one from the main body 2 side toward the traveling road side. Accordingly, the floor slab 7 has a rectangular shape in plan view with the horizontal direction X as the longitudinal direction. In the present embodiment, such floor slabs 7 are sequentially laid in the traveling direction Y so as to be supported on the plurality of floor slab support portions 6. The floor slab 7 is made of, for example, an iron plate or the like, and a sheet made of a rubber material or the like is preferably laid on the surface thereof as a slip stopper.

  Further, on the back surface of each floor slab piece 8 in the floor slab 7, that is, the surface facing downward in a state of being supported on the floor slab support 6, guide ribs 9 extending along the traveling direction Y are provided on each floor slab piece. Two per 8 are fixedly arranged. As shown in detail in FIG. 3, the guide rib 9 is disposed so as to cover the entire traveling direction Y on the back surface of each floor slab piece 8, and has an inclined surface 9 a that gradually rises upward toward the front side in the traveling direction Y. It is set as the preparation. That is, the guide rib 9 has a substantially triangular shape with the inclined surface 9a as one side when viewed from the traveling road side.

  In each floor slab 7, a friction material may be provided on at least one of the rear edge portion 7a facing the traveling direction Y rear side and the front edge portion 7b facing the traveling path side. Any friction material may be used as long as it can exhibit a high frictional force when it comes into contact with the body of the vehicle. Examples thereof include a member having a roughened surface and a rubber material. Further, the rear edge portion 7a and the front edge portion 7b itself may be roughened.

  Next, a method for supporting the floor slab 7 by the floor slab support 6 will be described. In this embodiment, as shown in FIG. 3, it is set as the structure by which the one floor slab 7 is arrange | positioned at the upper end of a pair of floor slab support parts 6 and 6 arrange | positioned adjacently. That is, each floor slab 7 is supported by a pair of floor slab support portions 6 and 6.

  The portion of the floor slab 7 on the rear side in the traveling direction Y, that is, the rear portion of the floor slab 7 is located on the rear side in the traveling direction Y of the pair of floor slab support portions 6 and 6 that support the floor slab 7. It is firmly fixed and integrated with the upper end of one floor slab support 6. This fixed integration is performed by welding or bolting, for example. Thus, even when an impact force at the time of a vehicle collision is exerted, the rear portion of the floor slab 7 and the floor slab support portion 6 can be integrated against the impact force. It is considered to be strong.

Further, the portion of the floor slab 7 on the front side in the traveling direction Y, that is, the front portion of the floor slab 7 is located on the front side in the traveling direction Y of the pair of floor slab support portions 6 and 6 that support the floor slab 7. It is placed on the other floor slab support 6. In addition, the front part of the floor slab 7 and the floor slab support part 6 may be welded with low joint strength. Thereby, when the impact force at the time of collision is exerted, the front part of the floor slab 7 is easily detached from the floor slab support part 6.
In addition, the notch part (illustration omitted) in which the guide rib 9 in the back surface of the floor slab 7 enters may be provided in the upper end of each floor slab support part 6. FIG.

  Thus, in this embodiment, the rear part of the floor slab 7 is fixed and integrated with the floor slab support 6 so as not to be detached, and the front part of the floor slab 7 is connected to the other floor slab support 6. On the other hand, it is configured to be detachably supported.

  Further, if attention is paid to the floor slab support 6, each floor slab support 6 excluding the floor slab support 6 disposed in the forward direction Y and the rearmost direction Y among the plurality of floor slab supports 6. Supports the front part of the floor slab 7 and the rear part of the other floor slab 7 located on the front side in the traveling direction Y of the floor slab 7. The floor slab support 6 disposed in the forefront of the traveling direction Y supports only the rear part of the one floor slab 7, and the floor slab support 6 disposed at the rearmost in the traveling direction Y is the same floor. Only the front part of the plate 7 is supported.

  In the platform 1 having such a configuration, when a large roll such as an earthquake occurs and the vehicle derails, the vehicle collides with a buffer portion 4A provided on the side edge 2a of the home body 2. At this time, the floor slab support section 6 in the buffer section 4A is set to be lower in strength than the body of the vehicle, so that the floor slab support section 6 is deformed in the traveling direction Y by an impact at the time of collision.

  When the floor slab support 6 is deformed in the traveling direction Y in this way, the floor slab 7 whose rear portion is fixedly integrated with the floor slab support 6 moves toward the front side in the traveling direction Y. become. At this time, since the front portion of the floor slab 7 is supported on the floor slab support portion 6 so as to be removable, the front portion of the floor slab 7 is easily detached from the floor slab support portion 6.

  As shown in FIG. 4, the floor slab 7 with the free front portion is laid on another floor slab 7 on which the inclined surface 9a of the guide rib 9 is located on the front side in the traveling direction Y. 7 is laminated on another floor slab 7. Then, as shown in FIG. 5, the floor slab 7 slides so as to sequentially overlap the floor slab 7 on the front side in the traveling direction Y.

As described above, according to the platform 1 of the present embodiment, the floor slab 7 is sequentially laid in the traveling direction Y, so that the floor slab 7 slides forward in the traveling direction Y when the vehicle collides. It will overlap with other floor slabs.
That is, when an impact force is applied to the floor slab 7, the floor slab 7 escapes toward the front side in the traveling direction Y without staying at the installation location, so that the impact force applied to the vehicle is accumulated. There is no increase, and damage to the vehicle from the floor slab 7 can be minimized.

  Further, as described above, when the vehicle collides with the buffer portion 4A of the platform 1, the floor slab support portion 6 is deformed to the front side in the traveling direction Y, and accordingly, the floor slab support portion 6 is fixedly integrated with the floor slab support portion 6. The floor slab 7 slides toward the front side in the traveling direction Y. Thereby, the floor slab 7 can be stacked on the other floor slab 7 on the front side in the traveling direction Y, and damage to the vehicle from the floor slab can be minimized. Further, since the floor slab 7 is fixed and integrated with the floor slab support 6 with a strength capable of resisting the impact force, the floor slab is prevented from being scattered by the impact force, thereby further enhancing the safety. Can be improved.

  Further, since the guide ribs 9 for guiding the floor slab 7 to the floor slab 7 on the front side in the traveling direction Y are provided on the back surface of the floor slab 7, the floor slab is surely placed on the other floor slab on the front side in the traveling direction. Can slide. Furthermore, since the guide rib 9 extends over the entire traveling direction Y on the back surface of the floor slab 7, the rigidity of the floor slab 7 itself can be improved, and the crowd load can be more reliably supported.

  Furthermore, each floor slab 7 is composed of a plurality of floor slab pieces 8 that are sequentially laid in the direction from the side edge toward the traveling road, that is, in the horizontal direction X. 7 slides forward in the direction of travel Y and overlaps with other floor slabs 7, and for example, as shown in FIG. 6, the floor slab pieces 8 in each floor slab 7 move to the home body 2 side. They will overlap each other. Thereby, the damage which a vehicle receives from a floor slab can be reduced further.

  Further, when the floor slab support 6 is formed into a flat truss shape, the floor slab support 6 is secured at the design stage while securing a load for supporting the crowd load on the floor slab 7 and the floor slab. It can be set as the structure which can deform | transform toward the advancing direction Y front side.

  Here, when there is almost no friction between the vehicle and the floor slab 7 at the time of the collision of the vehicle, the floor slab 7 is crushed toward the home body 2 side, and the floor slab 7 is moved in the traveling direction Y. It becomes difficult to move the slide. On the other hand, when a friction material is provided in at least one of the rear edge portion 7a and the front edge portion 7b of the floor slab, that is, the contact point with the vehicle at the time of the vehicle collision, the vehicle proceeds while colliding. Accordingly, the floor slab 7 itself in contact with the vehicle also moves so as to be pulled forward in the traveling direction Y according to the friction with the vehicle. Thereby, the floor slab 7 can be smoothly slid toward the front side in the traveling direction Y when the vehicle collides. The same applies to the case where the rear edge 7a and the front edge 7b are roughened.

As mentioned above, although embodiment of this invention was described in detail, unless it deviates from the technical idea of this invention, it is not limited to these, A some design change etc. are possible.
For example, the platform 10 provided with the buffer part 4B as shown in FIG. 7 as a modification may be used. In the platform 10 of this modified example, the plurality of floor slab support portions 6 are not arranged at regular intervals in the traveling direction Y, but are arranged at substantially the same distance as the dimension of the floor slab 7 in the traveling direction Y. The paired floor slab support portions 6 and 6 are arranged so as to be sequentially adjacent to each other in the traveling direction Y, and one floor slab 7 is supported on the pair of floor slab support portions 6 and 6. ing.

  The rear portion of the floor slab 7 is refracted downward, and the refracted portion is firmly fixed and integrated with the floor slab support portion 6 on the rear side in the traveling direction Y of the pair of floor slab support portions 6 and 6. It has become. The front portion of the floor slab 7 is detachably mounted on the floor slab support 6 on the front side in the traveling direction Y of the pair of floor slab supports 6 and 6. A guide rib 9 is provided on the back surface of the floor slab 7.

  Also in the platform 10 of the modified example having such a configuration, when an impact force is exerted at the time of a vehicle collision, the floor slab support portion 6 is deformed forward in the traveling direction Y as in the embodiment, and the floor slab is accordingly accompanied. 7 moves toward the front side in the traveling direction Y. At this time, as shown in FIG. 8, the front portion of the floor slab 7 is detached from the floor slab support portion 6 and guided by the guide rib 9, so that the floor slab 7 is moved forward in the traveling direction Y. Slide over the floor slab 7 and overlap.

  Therefore, also in the modified example, similarly to the embodiment, the damage that the vehicle receives from the floor slab 7 can be minimized. Further, since the floor slab 7 is fixed and integrated with the floor slab support 6 with a strength capable of resisting the impact force, the floor slab is prevented from being scattered by the impact force, thereby further enhancing the safety. Can be improved.

  Further, for example, the front portion of each floor slab 7 may be inclined upward without providing the guide rib 9. In this case, the front part of the floor slab functions as a guide part, and the floor slab can be slid on another floor slab on the front side in the traveling direction.

Next, a reference example of the platform according to the present invention will be described with reference to the drawings. In this reference example, the same components as those in the embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
As shown in FIG. 9, the platform 10 includes a platform body 2 provided on the side of the traveling path, and a buffer section provided on a side edge of the platform body 2 on the traveling path side. The home main body 2 and the buffer body 14 are provided so as to protrude toward the traveling road side of the vehicle over the entire length of the side edge 2a on the side of the home main body 2 in contact with the vehicle.

  The buffer part 14 has a predetermined mutual interval in the traveling direction Y of the vehicle, and a plurality of floor slab support parts 6 provided in an array, and a plurality of floor slabs 7 laid on the floor slab support parts 6. The plate-like reinforcing member 18 and the bar-like reinforcing member 19 are provided to reinforce the floor slab 7 from below.

  In the platform 10 in the reference example, as shown in FIGS. 10 and 11, a pair of floor slab support portions 6, 6 are arranged with an interval substantially equal to the dimension in the traveling direction Y of the floor slab 7. The floor slab support portions 6 and 6 are arranged so as to be sequentially adjacent to each other in the traveling direction Y. In addition, one floor slab 7 is supported on the pair of floor slab support portions 6 and 6. Note that the floor slab 7 has a rectangular shape in a plan view constituted by a plurality of floor slab pieces 8 as in the embodiment.

  The plate-like reinforcing member 18 is a member formed by bending a flat plate made of metal, for example. Specifically, as shown in FIG. 11, the plate-like reinforcing member 18 is in contact with the floor slab 7 from below and forms a flat shape parallel to the horizontal plane. A flat portion 18a, a flat shape parallel to the upper flat portion, that is, a flat shape parallel to the horizontal plane, and a lower flat portion 18b disposed below the upper flat portion 18a, and the upper flat portion 18a and the lower flat portion And a connection inclined portion 18c for connecting the portion 18b.

  In the present embodiment, the lower flat portion 18b is disposed on the rearmost side in the traveling direction Y of the plate-shaped reinforcing member 18, and the end portion on the rear side in the traveling direction Y of the lower flat portion 18b is fixed to the floor slab 7. ing. And, in the traveling direction Y front side of the lower flat portion 18b fixed to the floor slab 7 in this way, a connection inclined portion 18c that is gradually inclined upward toward the traveling direction Y front side is continuous, The upper flat portion 18a is continuous to the front side in the traveling direction Y of the connection inclined portion 18c. Further, a connecting inclined portion 18c that gradually inclines downward toward the front side in the traveling direction Y continues to the front side in the traveling direction Y of the upper flat portion 18a, and further in the traveling direction Y front of the connecting inclined portion 18c. The lower flat portion 18b is continuous with the lower flat portion 18b, and the end of the lower flat portion 18b in the traveling direction Y is fixed to the floor slab support portion 6.

As described above, in the plate-like reinforcing member 18 in the present embodiment, the lower flat portion 18b and the upper flat portion 18a are alternately arranged in the traveling direction Y, and the adjacent lower flat portion 18b and upper flat portion are adjacent to each other. 18a is connected by a connecting inclined portion 18c.
As a result, the plate-like reinforcing member 18 has a shape that can be easily buckled in the traveling direction Y.

  The rod-shaped reinforcing member 19 is a member having a substantially square shape formed by bending a metal linear rod-shaped member at the center in the longitudinal direction thereof, and is provided under the plate-shaped reinforcing member 18. That is, it is fixed to the back surface side of the lower flat portion 18b. Specifically, as shown in FIG. 10, the bar-shaped reinforcing member 19 is formed in the floor slab 7 with both end portions directed in the traveling direction Y and the vertex of the bent portion of the character shape directed toward the home body 2 side. Each floor slab piece 8 is provided so as to be positioned below the respective floor slab 7 so as to correspond one-to-one.

  Note that both ends of the bar-shaped reinforcing member 19 may be fixed to the floor slab support 6 respectively. Further, the bar-shaped reinforcing member 19 does not necessarily have a substantially U-shaped configuration, and may have another configuration such as a linear shape or an arc shape as long as the plate-shaped reinforcing member 18 can be supported from below. Good.

  In this way, the platform 10 in the reference example is provided along the traveling path of the vehicle, on the home body 2 provided on the side of the traveling path, and on the side edge on the traveling path side of the home body 2. In the platform 10 including the buffer portion 14, the buffer portion 14 extends from the side edge portion 2a toward the traveling road side, and is provided with a plurality of floor slabs spaced from each other in the traveling direction of the vehicle. A support portion 6, a plurality of floor slabs 7 laid sequentially in the traveling direction Y on the plurality of floor slab support portions 6, and the floor slab 7 are supported from below and seated in the traveling direction Y. A plate-shaped reinforcing member 18 that can be bent is provided.

  Therefore, when a large roll such as an earthquake occurs and the vehicle derails and the vehicle collides with the buffer portion 14 provided on the side edge 2a of the home body 2, the plate-like reinforcing member 18 can buckle. Since the buffer portion 14 itself is easily buckled in the traveling direction Y because of the configuration, it is possible to effectively absorb the kinetic energy of the vehicle and reduce the impact applied to the vehicle body.

  The plate-like reinforcing member 18 includes an upper flat portion 18a that is in contact with the floor slab 7 and a lower flat portion 18b that is spaced apart from the floor slab 7 and is parallel to the upper flat portion 18a. The connecting flat portions 18c that are alternately disposed toward the upper side and connect the upper flat portions 18a and the lower flat portions 18b in the traveling direction Y are provided.

  As a result, when the vehicle collides, the plate-like reinforcing member 18 is easily buckled in the traveling direction Y, and the impact on the vehicle body can be effectively reduced.

  Further, in the present reference example, the plate-like reinforcing member 18 is supported from below, and the rod-like reinforcing member 19 extending in the traveling direction Y is provided. The load can be supported.

  Further, since the rod-shaped reinforcing member 19 is bent so as to protrude in the horizontal direction X orthogonal to the traveling direction Y, the vehicle-shaped collision is performed while the plate-shaped reinforcing member 18 is securely held. Sometimes it will be easily buckled. Therefore, it is possible to reduce the impact applied to the vehicle body while supporting the crowd load.

In this reference example, for example, as shown in FIG. 12, each floor slab piece 8 constituting the floor slab 7 may be divided into two in the traveling direction Y. That is, in this configuration, each floor slab piece 8 is composed of two divided floor slab pieces 8a and 8b.
About the aspect of the division of the floor slab piece 8, as in the floor slab 7 on the front side in the traveling direction Y of the two floor slabs 7 in FIG. Each floor slab piece 8 may be divided by a line k1.

  Further, like the floor slab 7 on the traveling direction Y rear side of the two floor slabs 7 in FIG. 12, the dividing line k2 that gradually inclines toward the traveling direction Y rear side from the home body 2 toward the traveling path side. Therefore, the configuration may be such that each floor slab piece 8 is divided.

  When the floor slab piece 8 is divided into the divided floor slab pieces 8 a and 8 b as described above, each floor slab piece 8 is caused to follow the buckling of the plate-like reinforcing member 18 when the vehicle collides with the buffer portion 14. Can be deformed. Therefore, since the buffer portion 14 can be buckled more easily, the impact applied to the vehicle body can be more effectively reduced.
