Description

  The present invention relates to a temporary bridge between railway platforms for transporting heavy parts of equipment such as an escalator from one railway platform to the other railway platform.

  When installing equipment such as escalators, elevators, and other railway station equipment and vending machines on the platform, depending on the location of the area around the station, heavy equipment such as heavy components and equipment can be carried into one platform. It may not be possible to carry directly into the opposite home that is planned to be installed from outside roads.

  The use of existing stepped bridges, underpasses, and elevators between platforms to transport heavy objects from one platform to the opposite platform is often quite difficult and sometimes impossible. is there.

  In a relative type platform, the other platform can be seen from one platform across the track. Therefore, a temporary bridge is built between the two platforms at night when railway operation is suspended, and the weight from one platform to the other platform is increased. It is easy to carry in things with little labor.

  However, in a limited time, it is necessary to assemble and transport a strong temporary bridge for transporting heavy objects, disassemble and remove the assembled temporary bridge. Not yet commercialized.

  Temporary bridges across rivers and valleys are well known. For example, Patent Document 1 discloses that a tall precast concrete foundation material is placed on the lower side of both banks with a difference in height, a concrete is disposed on the other bank, the level is taken, and a temporary bridge is built. Yes. Further, Patent Document 2 discloses a temporary humanitarian bridge in which a bridge floor is laid on the lower surface flange of the main girder to reduce the height difference between the bridge floor and the ground.

  Since these temporary bridges are temporary, they are relatively easy to install and remove, but it is not envisaged or impossible to finish the installation and removal in a short time at night. . Also, no special consideration has been given to avoid excavating or damaging existing existing shores and road surfaces.

Japanese Patent Laid-Open No. 10-72808

  The present invention has been made to solve the above-described problems, and the object of the present invention is to provide a space between railway platforms that can be temporarily installed and removed in a short time and can transport heavy objects without damaging the railway facilities. It is intended to provide a temporary bridge.

  In order to solve the above-mentioned problem, the temporary bridge between railway platforms of the present invention is arranged in parallel with each other and has two guide rails for carrying heavy loads that have a length exceeding both the home end panels of the relative railway platform. And a guide panel placed on the upper surface of the railroad platform and supporting the end portion of the guide rail beyond the home end panel on the upper surface, and a guide rail between the relative rail platform and the guide rail. A plurality of height adjustment posts that support a portion of the track, a plurality of cross beams that connect the two guide rails to keep the two guide rails parallel, and lay on the plurality of cross beams And a scaffold plate.

  In the said invention, if it has a connecting material which connects between said several height adjustment support | pillars, the intensity | strength of a bridge will rise and a conveyance operation | work will become safer. In addition, if the cross section of the guide rail is U-shaped, it can be mounted on a heavy object or a caster with a heavy object placed on the guide rail to be transported. The risk of doing so is eliminated.

  In this invention, the two guide rails for transporting heavy objects are used as the main girder of the temporary bridge, the guide rail is supported by the height adjusting column and the curing panel, and both guide rails are connected by the horizontal girder. Since the scaffolding is laid on the cross beam, the steps between the platform, the guide rail and the scaffolding are small, making it possible to carry heavy objects easily, and to make temporary and removal work in a short time. There is no damage to railway facilities such as surfaces and tracks.

  Embodiments according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a longitudinal sectional view showing an embodiment of the present invention, FIG. 2 is a plan view showing the embodiment of FIG. 1, and FIG. 3 is a transverse sectional view showing the embodiment of FIG.

  1 and 2, 1 is a temporary bridge between railway platforms, 2 is a guide rail, 3 is a curing panel, 4 is a height adjusting column, 5 is a cross beam, and 6 is a scaffolding plate.

  The guide rail 2 has a length that can be bridged between the two platforms P1 and P2 of the relative railway platform, and the two guide rails 2 and 2 are arranged in parallel to each other. As shown in FIG. 3, each guide rail 2 is made of a U-shaped steel material having a concave upper section, and a caster or a heavy object is mounted on the heavy object in the U-shaped groove. It is designed to carry a dolly caster. Although the detailed illustration of the guide rail 2 is omitted, a plurality of rails are connected so that the guide rail 2 itself can be easily carried. Rails and rail joints are connected so that there are no major steps or deviations. Of course, depending on the installation location, the long guide rail 2 may be constituted by one rail without a joint.

  The curing panel 3 is placed on the upper surface of each of the homes P1, P2, and supports the end portion 21 of the guide rail 2 on the upper surface. The synthetic resin plate, the wooden plate, the thick synthetic resin sheet, etc. A material that does not damage the top surface of the home even when a heavy load is applied is selected.

  The cross-sectional shape of the guide rail 2 may be an L shape that guides the caster while facing the outer side or the inner side of the caster, in addition to a U shape (a U-shaped concave portion facing upward) surrounding both sides of the caster.

  In general, in a railroad platform, a home end panel PP protrudes on the side of the track so as to ensure the safety of the feet when passengers get on and off, approaching the side surface of the stopped vehicle. Since the home end panel PP has an overhang structure, it is not suitable for supporting a heavy load. Therefore, the curing panel 3 supports the end portion 21 of the guide rail 2 at a position beyond the home end panel PP so that a heavy load to be conveyed is not applied to the home end panel PP.

  A plurality of the height adjusting columns 4 are provided on the roadbed G between the railroad platforms P1 and P2, and in this embodiment, the height adjusting columns 4 are erected at substantially equal intervals to support a portion of the guide rail 2 on the track. The height adjustment column 4 can be adjusted freely by a worker like a jack, and is adjusted as appropriate according to the uneven roadbed G to support the guide rail 2 horizontally.

  The cross beam 5 is for connecting the two guide rails 2 and 2 to keep the two guide rails 2 and 2 parallel, and in this embodiment, the height adjustment support 4 A channel material 51 having a U-shaped cross section is provided at each end of each cross beam 5 and the guide rail 2 is accommodated in the channel material 51, and the guide rail 2 is then connected to the channel material 51. It is fixed to. The distance between the channel members 51 and 51 at both ends of the cross beam 5 is equal, and the two guide rails 2 and 2 are arranged in parallel.

  The upper end portion 41 of the height adjustment column 4 is fixed to the bottom surface of the channel material 51 by bolting or the like. The cross beam 5 can be directly fixed to the guide rail 2 by screwing or the like without using the channel material 51. In this case, the upper end portion 41 of the height adjusting column 4 is fixed to the bottom surface of the guide rail 2 by bolting or the like.

  The said scaffold board 6 becomes a scaffold of the worker in the case of heavy article conveyance. The scaffold plate 6 is laid on the plurality of cross beams 5 and 5. It is desirable for work that both ends are on the curing panel 3. Since the scaffolding plate 6 is also long like the guide rail 2, for the convenience of carrying in the scaffolding plate 6 itself, it may be appropriately divided into a plurality of pieces. If necessary, it is desirable to connect the seam or fix it to the cross beam 5 to stabilize the operation and make it safe.

  The height adjustment columns 4 and 4 that support the guide rail 2 from below also receive a lateral load due to heavy material conveyance on the scaffolding plate 6. Therefore, the height adjusting struts 4 and 4 are connected to each other by a connecting material to strengthen the structure. In this embodiment, the head joint 7, the root joint 8, and the diagonal member 9 shown in FIGS. 1 and 3 are the joint members. The head tether 7 and the root tether 8 are coupled to the height adjusting posts 4 and 4 by known clamps (joint fittings) 71 and 81, and further, the diagonal member 9 is coupled to the head tether 7 and the root tether 8 by the clamp 91. As a result, a highly rigid triangular structure is formed.

  Reference numeral 10 denotes a height adjustment column that supports the home end panel PP from the roadbed G, and 11 denotes a railroad rail.

  The railway platform temporary bridge of the present invention configured as described above is strong by bringing parts such as the guide rail 2, the height adjusting column 4, the cross beam 5 and the scaffolding plate 6 into the bridge site and assembling in a short time. The temporary bridge 1 can be completed. The completed temporary bridge 1 is stable with few steps from the homes P1 and P2, and can carry heavy objects from the home to the home only by horizontal movement along the guide rail 2. After using the temporary bridge 1, it can be quickly dismantled and removed.

The longitudinal cross-sectional view which shows one embodiment of this invention. The top view which shows embodiment of FIG. FIG. 2 is a transverse sectional view showing the embodiment of FIG. 1.
