Description

Technical Field

[0001] The present invention relates to a cable trough assembly for a home door for accommodating a home door cable electrically connected to the home door of an embankment type platform, a cable support base, and an installation structure and installation method thereof.

Background Art

[0002] Conventionally, an installation method of a cable connected to a home door arranged along the outer edge on the line side of an embankment type platform has been studied. For example, Patent Document 1 discloses an invention in which a cable is installed along the back surface of a plurality of braille blocks continuously installed on a platform. According to this method, cable installation work and maintenance work can be easily performed only by installing and removing the braille blocks, but there are problems in workability in that it is necessary to excavate embankment along the arrangement of the braille blocks and there is a labor in removing the braille blocks during maintenance.

[0003] In response to that problem, in recent years, as shown in Patent Documents 2 to 4, a cable installation method using a cable trough has been studied. Patent Document 2 discloses a cable trough having a simple structure and capable of securely fixing a cable to a trough main body.

[0004] Further, Patent Document 3 discloses a cable installation method using a cable cabinet in which an embankment excavation space having substantially the same height as the cross beam is formed between a plurality of adjacent cross beams, and the cable cabinet has a vertical wall and a bottom plate and the line side with a substantially L-shaped cross section is open. According to this method, it is possible to reduce the amount of excavated soil and realize a structure that does not require a cable rack. However, depending on the construction site, there are problems that the surface of the cable is damaged or the necessary cables cannot be arranged according to the purpose, use, and type of the cable due to insufficient cable accommodation capacity in the trough.

[0005] Furthermore, Patent Document 4 discloses a cable installation method in which a resin cable trough with a roughly U-shaped cross-section is positioned with a side plate having a handhole drilled in it exposed to the track side, and the cable is installed using the handhole. This method can improve the workability of cable installation work. In this method, since a resin cable trough with a roughly U-shaped cross-section is used, the rigidity of the trough can be increased compared to a roughly L-shaped trough, but there is a problem that the workability is somewhat lacking.

[0006] [Patent Document 1] Japanese Patent Publication No. 2012-245841 [Patent Document 2] Patent No. 7269451 [Patent Document 3] Japanese Patent Publication No. 2017-017801 [Patent Document 4] Patent No. 7361238 [Overview of the project] [Problems that the invention aims to solve]

[0007] Furthermore, in recent years, the adoption of wireless platform door interlocking systems has created a need for cable laying structures that can accommodate the increased number of cables to be wired to the platform. When installing cables for embankment-type platform doors using cable troughs, the cable route is limited to the outer edge of the platform on the track side. As a result, the cable capacity of the trough may be insufficient, potentially causing multiple cables to interfere with each other and damage the cable surface. Consequently, in sites with a large number of cables, work efficiency may be reduced due to entanglement of cables during installation, and manageability may be reduced during maintenance after installation due to poor visibility of each cable from the track side, making it difficult to identify the type of cable and its connection relationships. In this regard, the cable trough described in Patent Document 2 and the cable installation methods described in Patent Documents 3-4 do not explicitly address this issue, raising concerns that they cannot improve work efficiency during installation and manageability after installation for platform door cables. Furthermore, methods for expanding cable routes by constructing home walls instead of cable troughs are also being studied, but these methods have drawbacks such as requiring extensive removal of stonework and excavation of embankments, necessitating large-scale earth retention work, and increasing costs and construction time due to the difficulty in securing stockyards at urban stations.

[0008] Therefore, the present invention was devised in view of the above-mentioned problems, and its objective is to provide a cable trough assembly for platform screen doors, a cable support base, and an installation structure and installation method thereof, which can increase the cable storage capacity within the cable trough and improve workability during installation and manageability after installation. [Means for solving the problem]

The cable support is characterized by having a resin fitting leg portion that fits into the upper end of the second side plate and a resin base portion that extends continuously from the fitting leg portion toward the first side plate.

[0018] The installation structure for a platform door cable trough assembly in the 10th invention is an installation structure for a platform door cable trough assembly that can be assembled on-site to house platform door cables that are electrically connected to platform doors arranged along the outer edge of the track side of an embankment-type platform, and comprises a platform door cable trough assembly described in any of the 1st to 4th inventions, wherein the trough body is installed in a space formed below the platform door with the inner surface of the bottom plate oriented substantially upward and the second side plate exposed to the track side.

[0019] The installation structure for platform door cables in the 11th invention is an installation structure for platform door cables in which platform door cables, which are electrically connected to platform door cables arranged along the outer edge on the track side of an embankment-type platform, are housed in a platform door cable trough assembly that can be assembled on-site, and comprises a platform door cable trough assembly according to any of the 1st to 4th inventions, and a plurality of platform door cables installed in the upper space above the base portion and the lower space below the base portion of the opening space of the platform door cable trough assembly, wherein the trough body is installed in a space formed below the platform door with the inner surface of the bottom plate oriented substantially upward and the second side plate exposed to the track side.

[0020] The installation method for a platform door cable trough assembly according to the 12th invention is an installation method for a platform door cable trough assembly that can be assembled on-site to house platform door cables that are electrically connected to platform doors arranged along the outer edge on the track side of an embankment-type platform, and is characterized by comprising: an assembly step of assembling a platform door cable trough assembly by fitting a resin cable support base having a fitting leg portion that fits onto the upper end of the second side plate and a base portion that extends continuously from the fitting leg portion toward the first side plate into a resin trough body having an opening space formed thereon, which has a bottom plate and first side plates that form an embankment-side retaining wall that rises upright from both ends in the width direction of the bottom plate and facing each other, and a second side plate that is lower than the upper end of the first side plate; and a trough installation step of installing the platform door cable trough assembly assembled in the assembly step into a space formed below the platform door, with the inner surface of the bottom plate oriented substantially upward and the second side plate exposed toward the track side.

[0021] The installation method of the cable trough assembly for the home door in the 13th invention is, in the 12th invention, in the assembly process, a resin U-shaped trough body having a bottom plate and one side plate and the other side plate forming retaining earth on the retaining earth side standing upright from both ends in the width direction of the bottom plate, in which an opening space having a substantially U-shaped cross section is formed, is used with the other side plate cut by a predetermined length from the upper end so as to be lower than the upper end of the one side plate, or with an extension side plate made of resin forming retaining earth fitted above the one side plate so as to be higher than the upper end of the other side plate.

[0022] The installation method of the cable trough assembly for the home door in the 14th invention has a cable installation process of installing a plurality of cables for the home door from the line side so as to pass through an upper space above the pedestal portion and a lower space below the pedestal portion in the opening space of the cable trough assembly for the home door installed by the installation method of the cable trough assembly for the home door described in the 12th invention or the 13th invention.

Effect of the Invention

[0023] According to the 1st to 8th inventions, the cable trough assembly for the home door includes a resin trough body having an opening space with a second side plate lower than the upper end of the first side plate, and a resin cable pedestal having a pedestal portion continuously extending from a fitting leg portion fitted to the upper end of the second side plate toward the first side plate. Therefore, by installing cables in the upper space and the lower space divided through the pedestal portion in the opening space respectively, interference between the cables can be suppressed. Thereby, it is possible to improve the workability during installation and the manageability after installation for the cables for the home door. Also, since the trough body and the cable pedestal are made of resin, they can be easily cut on site to adjust the height. Thereby, it is possible to improve the workability during installation for the cables for the home door.

[0024] In particular, according to the second invention, the trough body further has a fitting portion for fitting a resin extension side plate that forms a retaining wall above the first side plate. Therefore, the height of the opening space can be adjusted according to the number of cables, and the amount of earth excavation for the embankment can be reduced. Thereby, the workability when installing the cable trough assembly for the home door can be improved.

[0025] In particular, according to the third invention, the trough body is formed with a slit that penetrates from the fitting portion where the upper end of the first side plate is recessed downward to the surface of the first side plate. Therefore, the embankment that has entered the fitting portion and the infiltrated water in the embankment can be discharged. Thereby, the durability of the cable trough assembly for the home door can be improved.

[0026] In particular, according to the fourth invention, it further includes an extension side plate provided with a cable hole for inserting a cable for wireless communication. Therefore, for the cable for wireless communication arranged above the home door, a route can be secured to pass through the cable hole from the opening space of the trough body and rise around the home pillar, and a route to connect to a device above the home door along the home pillar. This can prevent the cable for wireless communication from interfering with the operation of the home door. Thereby, the workability during installation and the manageability after installation of the cable for wireless communication can be improved.

[0027] In particular, according to the fifth invention, the cable support has a notch formed in the pedestal portion that communicates the upper space and the lower space. Therefore, by passing the cable through the notch and arranging it, the rising wiring of the cable can be easily implemented. Thereby, the workability during installation and the manageability after installation of the cable for the home door can be further improved.

[0028] In particular, according to the sixth invention, the cable support base has a shorter longitudinal length than the trough body. Therefore, many cable wiring patterns can be applied using the upper and lower spaces, which are divided within the opening space via the base. In addition, it is easier to secure working space for workers in areas where there is no cable support base. As a result, it is possible to further improve the workability during installation and the manageability after installation for platform door cables.

[0029] In particular, according to the seventh invention, the cable support base further has a movable housing that is slidable in the width direction on the base. Therefore, by pulling the movable housing towards the track side, the wiring of the cables installed inside and their visibility after installation can be reliably carried out. This makes it possible to further improve the workability during installation and the manageability after installation of platform door cables.

[0030] In particular, according to the eighth invention, the cable support base has support legs that extend downward from the lower surface of the base and contact the bottom plate. Therefore, the cable support base is less likely to be damaged by load. This improves the durability of the cable trough assembly for platform doors. In addition, there is no need to fix the base to the first side plate, eliminating the need for bolting and other such work. This also improves the durability of the cable trough assembly for platform doors. Furthermore, when the support legs are provided spaced apart from the first side plate, the cables can be installed in the lower space divided by the support legs into one lower space and the other lower space, thereby further suppressing interference between cables. This further improves the workability during installation and the manageability after installation of the cables for platform doors.

[0031] According to the ninth invention, the cable support base has a resin fitting leg that fits onto the upper end of the second side plate of the platform door cable trough assembly, and a resin base that extends continuously from the fitting leg toward the first side plate. Therefore, by installing cables in the upper and lower spaces, which are divided within the opening space via the base, interference between cables can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables.

[0032] According to the tenth invention, the installation structure for the platform door cable trough assembly comprises the platform door cable trough assembly described in any of the first to third inventions, wherein the trough body is installed with the inner surface of the bottom plate oriented substantially upward and the second side plate exposed to the track side. Therefore, by installing cables in the upper and lower spaces, which are divided within the opening space via the base portion, interference between cables can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables.

[0033] According to the 11th invention, the installation structure for platform door cables comprises a platform door cable trough assembly described in any of the 1st to 3rd inventions, and a plurality of platform door cables installed in the upper space and the lower space, respectively. The trough body is installed with the inner surface of the bottom plate oriented substantially upward and the second side plate exposed to the track side. Therefore, by installing the cables from the track side in both the upper and lower spaces, interference between the cables can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables.

[0034] According to the 12th to 13th inventions, the installation method for a platform door cable trough assembly comprises an assembly step of assembling a platform door cable trough assembly by fitting a resin cable support base into a resin trough body having an opening space formed therein, which has a second side plate lower than the upper end of the first side plate; and a trough installation step of installing the platform door cable trough assembly in a space formed below the platform door, with the inner surface of the bottom plate oriented substantially upward and the second side plate exposed to the track side. As a result, by installing cables from the track side in the upper and lower spaces, which are divided within the opening space via a base, interference between cables can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables.

[0035] In particular, according to the 13th invention, the assembly process uses a trough body made of resin with a substantially U-shaped opening space in cross-section, which is formed by cutting the other side plate by a predetermined length from the top so that it is lower than the top end of one side plate, or by fitting a resin extension side plate that forms a retaining wall above one side plate so that it is higher than the top end of the other side plate. As a result, the height of the upper and lower spaces can be adjusted according to the number of cables. This improves the convenience of installation for platform door cables.

[0036] According to the 14th invention, the installation method for platform screen door cables includes a cable installation step in which multiple platform screen door cables are installed from the track side so as to pass through the upper space and lower space of the platform screen door cable trough assembly installed by the installation method for platform screen door cable trough assembly described in the 12th or 13th invention. Therefore, by installing cables from the track side in both the upper and lower spaces, interference between cables can be suppressed. This improves the workability during installation and the manageability after installation of platform screen door cables. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0038] Hereinafter, with reference to the drawings, an example of an installation structure 1 for platform screen door cables and an example of a platform screen door cable trough assembly 2 as embodiments of the present invention will be described in detail. In each figure, the first direction is referred to as X, the second direction is referred to as Y as one direction perpendicular to the first direction X, and the third direction is referred to as Z as the direction perpendicular to both the first direction X and the second direction Y. The configurations in each figure are schematically shown for illustrative purposes, and for example, the size of each component and the size comparisons between components may differ from those shown in the figures.

[0039] (Installation structure for platform screen door cables 1) Referring to the drawings, an example of the platform door cable installation structure 1 and the platform door cable trough assembly 2 in this embodiment will be described. In the following description, when the cable trough assembly 2 or simply the cable trough is mentioned, it refers to the platform door cable trough assembly 2. Also, when simply referred to as the cable, it refers to the platform door cables C1, C2, and C that are part of the platform door cable installation structure 1. Note that the platform door cables C1, C2, and C include, for example, signal transmission lines that send opening and closing operation signals for platform doors 11 and 12, and power supply lines that send electricity that powers the opening and closing operation. Furthermore, platform door cable C may be a cable directly connected to platform doors 11 and 12, similar to platform door cables C1 and C2, or it may be a cable that is raised above platform doors 11 and 12 and directly connected to various devices such as wireless equipment installed in the platform canopy used to determine whether or not platform doors 11 and 12 can be opened or closed, as shown in Figure 1.

[0040] The installation structure 1 for the platform screen door cable constitutes part of the installation structure for the platform screen door, which is positioned along the outer edge of the embankment platform on the track side (track-side outer edge). The embankment platform and the track-side outer edge extend, for example, in a first direction X.

[0041] The platform screen door installation structure consists of, for example, platform screen doors 11 and 12, a partition wall 13 connecting the platform screen doors 11 and 12, an end tile 14 supporting them from below, a platform base F11, a platform surface F12, and a platform screen door cable installation structure 1, as shown in Figures 1 to 3. Figure 1 is a schematic front view showing an example of a platform screen door installation structure including the platform screen door cable installation structure 1. Figure 2 shows the AA section of Figure 1, and Figure 3 shows the BB section of Figure 1.

[0042] Here, the platform door cable installation structure 1 refers to a structure installed in an excavated space formed below the platform doors 11 and 12 so as to be spaced apart from each other along the outer edge on the track side and exposed to the track side. It comprises one or more cable trough assemblies 2, platform door cables C1 and C2 shown by solid lines in Figure 1, and platform door cable C (additional cable) shown by a dashed line in Figure 1. The excavated space is a space formed by excavating the embankment that constitutes the platform foundation F11 using known construction machinery or the like. Note that the space in which the platform door cable installation structure 1 is installed is not limited to the excavated space, but may also be a space in the platform foundation F11 which has a roughly L-shaped or roughly T-shaped cross-section.

[0043] In this case, the platform door installation structure is such that the platform door cables C1, C2, and C are installed so as to pass through the opening space Q inside the cable trough assembly 2, thereby electrically connecting each platform door 11, 12 and the equipment inside the platform. The opening space Q can be viewed from the track side, for example, as shown in Figures 2 and 3, and workers can insert their hands or tools into it.

[0044] In the installation structure 1 for platform screen door cables, a cable trough assembly 2 is installed in the area shown in Figure 2, in which a cable support base 22 and an extension side plate 23 are fitted onto a trough body 21. In this case, the platform screen door cables C1, C2, and C can be installed in the upper space Q1 above the cable support base 22 and the lower space Q2 below it, respectively, and interference between the cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation for the platform screen door cables C1, C2, and C.

[0045] Furthermore, in the installation structure 1 for the platform screen door cables, a cable trough assembly 2' consisting of a trough body 21' having the same configuration and material as the trough body 21 is installed in the area shown in Figure 3. In other words, in the area shown in Figure 3, only an excavation space is needed to install the trough body 21, which is secured only for the space to install each platform screen door cable C1 and C2 in the cable route where it is not necessary to pass the platform screen door cable C, thus reducing the amount of embankment excavation. This improves the workability during installation of the platform screen door cables C1, C2, and C.

[0046] Furthermore, since the installation structure 1 for platform screen doors uses cable trough assemblies 2 and 2' that can be assembled on-site, even if the installation structure 1 for platform screen doors differs from site to site, the size of the excavation space can be minimized and the amount of embankment excavation can be reduced by deciding on-site whether or not to include the cable support 22 and extension side plates 23 for the same trough body 21 and 21', or by cutting the trough body 21 and 21' on-site to adjust the height.

[0047] Since platform door 12 is the same as platform door 11, the corresponding configuration will be indicated in parentheses as needed in the following explanation, and similar explanations will be omitted.

[0048] <Platform doors 11 (12)> The platform screen doors 11(12) are known movable platform screen doors that prevent passengers from falling onto the tracks or coming into contact with trains. The platform screen doors 11(12) are installed along the outer edge of an embankment platform on the track side. The platform screen doors 11(12) are electrically powered and can be controlled by being electrically connected to an external power source (not shown) via platform screen door cables C1, C2, and C, and receiving power and transmitting control signals. The platform screen doors 11 and 12 are arranged at a predetermined distance apart from each other, for example, according to the door spacing of trains that stop at the platform.

[0049] The platform door 11(12) includes, for example, a door housing 111(121), a door control unit 112(122), and a door 113(123). The door housing 111(121) is equipped with the door control unit 112(122). The door housing 111(121) houses the door 113(123) when opening the platform door 11(12) and releases the door 113(123) to the outside when closing. The door control unit 112(122) is powered via the platform door cable C1 and controls the opening and closing operation of the platform door 11(12).

[0050] <Bulkhead 13> The bulkhead 13 is a well-known platform barrier designed to prevent passengers from falling onto the tracks or coming into contact with trains. The bulkhead 13 connects, for example, platform doors 11 and platform doors 12.

[0051] <Tip Tile 14> The end tile 14 is a known platform end tile that serves as an entrance / exit for passengers when boarding and alighting from the train. The end tile 14 is installed, for example, along the outer edge on the track side of an embankment platform above the platform foundation F11 and supports the platform doors 11(12).

[0052] <Platform base section F11> The platform foundation F11 is the foundation of the platform. The platform foundation F11 is composed of, for example, embankment, PC (Prestressed Concrete) slab, concrete blocks, etc. The excavated space mentioned above is the space where the embankment constituting the platform foundation F11 has been excavated. The area around the platform foundation F11, especially around the excavated space, may be reinforced with, for example, a PC slab or concrete blocks.

[0053] <Platform surface layer F12> The platform surface layer F12 is the surface layer above the foundation of the platform, excluding the tip tiles 14. The platform surface layer F12 is composed of, for example, a precast concrete slab, concrete, etc.

[0054] <Cable trough assembly 2, 2'> Cable trough assemblies 2 and 2' are troughs for housing and protecting platform door cables C1, C2, and C. Cable trough assembly 2 comprises a trough body 21 and a cable support base 22, as shown in Figures 4 to 8, for example. Cable trough assembly 2' consists only of the trough body 21' without the cable support base 22 and extension side plate 23 fitted together, as shown in Figure 9, for example. Cable trough assembly 2 may further include extension side plates 23, as shown in Figures 10 to 12, for example. Figure 4 shows a schematic front view of an example of cable trough assembly 2, Figure 5 shows a schematic plan view of an example of cable trough assembly 2, and Figures 6 to 8 show schematic cross-sectional views corresponding to the CC, DD, and EE sections of Figure 4, respectively. Figure 9 shows a side view of cable trough assembly 2' consisting of the trough body 21 without the cable support base 22 and extension side plate 23 fitted together. Figure 10 is a schematic cross-sectional view showing an example of a trough body 21 and extension side plate 23, and Figures 11 and 12 are schematic perspective views showing an example of a fitting method between the trough body 21 and the extension side plate 23.

[0055] Here, the trough body 21 is made of resin, for example, and has a bottom plate 210, first side plates 211 that stand upright facing each other from both ends of the bottom plate 210 in the width direction (third direction Z in Figure 6) and form an embankment-side retaining wall, and a second side plate 212 that is lower than the upper end of the first side plate 211, and an opening space Q is formed inside. The cable support base 22 is made of resin, for example, and has a fitting leg portion 221 that fits onto the upper end of the second side plate 212, and a base portion 222 that extends continuously from the fitting leg portion 221 toward the first side plate 211. Furthermore, the cable trough assembly 2 can be assembled on site by fitting the trough body 21 and the cable support base 22 together. In this case, for example as shown in Figure 2, by installing cables C1, C2, and C in the upper space Q1 and the lower space Q2, respectively, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. Specifically, for example, physical interference between cables C1, C2, and C, and interference caused by electrical noise resulting from induced currents can be suppressed. This improves the workability during installation and the manageability after installation of platform screen door cables C1, C2, and C. In addition, since the trough body 21 and cable support base 22 are made of resin, they can be easily cut and adjusted in height on site. This further improves the workability during installation of platform screen door cables C1, C2, and C.

[0056] Thus, the cable trough assembly 2 has a first side plate 211 that is taller than the second side plate 212, the first side plate 211 is used for retaining the soil of the embankment, and a cable support base 22 that fits onto the upper end of the second side plate 212, making it possible to stably position the cable support base 22 inside the trough body 21. Furthermore, the cable trough assembly 2 can accommodate cables in two separate spaces, the lower and upper parts of the base portion 222 of the cable support base 22, depending on the purpose, use, type, and number of cables to be housed in the cable trough assembly 2. This increases the amount of cable that can be housed and makes management easier.

[0057] <Installation structure of cable trough assembly 2,2'> The cable trough assembly 2 is installed in the installation structure 1 for platform doors shown in Figure 2, for example, in the excavated space formed below the platform doors 11 and 12, with the inner surface of the bottom plate 210 oriented approximately upward (second direction Y) and the second side plate 212 exposed to the track side. The installation structure 1 for platform doors also includes the cable trough assembly 2 and a plurality of platform door cables C1, C2, and C installed in the upper space Q1 above the base portion 222 of the cable support base 22 and the lower space Q2 below the base portion 222, respectively. The cable support base 22 is fitted and fixed to the second side plate 212. In this case, by installing the cables C1, C2, and C from the track side in the upper space Q1 and the lower space Q2, which are divided in the opening space Q via the base portion 222, interference between the cables C1, C2, and C can be suppressed. Specifically, this technology can suppress physical interference between cables C1, C2, and C, as well as electrical noise interference caused by induced currents. This improves the ease of installation and post-installation management of platform screen door cables C1, C2, and C.

[0058] Thus, the installation structure of the cable trough assembly 2 has the first side plate 211 positioned on the embankment side of the platform and the second side plate 212 positioned on the track side. This allows the inside of the trough body 21 to be visible from the track side during construction, and also allows for confirmation of the status of the cables placed on the cable support base 22, resulting in excellent workability. Furthermore, because the cable support base 22 is fitted with the second side plate 212, the cable support base 22 can be stably held within the trough even in the event of an earthquake. In addition, the cable support base 22 allows for the arrangement of cables in the space above and below the cable support base 22 according to their purpose, use, type, and number. In this case, cable management is easier, and it is possible to prevent cables from coming into contact with each other and damaging their surfaces during construction. Furthermore, by providing an extension side plate 23 above the first side plate 211, it can be applied even when the embankment height is high, and the number of cables that can be accommodated can be increased in that case. Furthermore, as described later, by providing a slit 211b above the first side plate 211, it is possible to achieve a drainage effect that discharges water that has entered the recess for fitting the extension side plate 23, and an effect that alleviates localized stress concentration on the first side plate 211 by elastically modifying the area around the slit of the first side plate 211.

[0059] Since the trough body 21' has the same shape, material, and function as the trough body 21, it will be omitted from the following explanation.

[0060] <Trough body 21> The trough body 21 is a hollow body that extends in the longitudinal direction (first direction X) and has an opening space Q inside, as shown in Figures 4 and 5, for example.

[0061] The trough body 21, as shown in Figures 6 and 9, for example, has a base plate 210, first side plates 211 that form an embankment-side retaining wall and stand upright opposite each other from both ends of the base plate 210 in the width direction (third direction Z in Figure 6), and a second side plate 212 that is lower than the upper end of the first side plate 211. The trough body 21 forms an opening space Q including, for example, an upper space Q1 and a lower space Q2. As for the material of the trough body 21, from the viewpoint of workability during installation, a lightweight and cuttable resin material is used instead of steel or concrete. The trough body 21 has a cross-section that is approximately L-shaped or J-shaped, for example, perpendicular to the first direction X.

[0062] The dimensions of the trough body 21 are as follows: for example, the bottom plate 210 is a roughly flat shape with a length of approximately 633 mm to 972 mm in the first direction X, a height of approximately 35 mm in the second direction Y, and a width of approximately 550 mm in the third direction Z; the first side plate 211 is a roughly flat shape with a length of approximately 633 mm to 972 mm in the first direction X, a height of approximately 320 mm to 360 mm in the second direction Y, and a width of approximately 42 mm to 54 mm in the third direction Z; and the second side plate 212 is a roughly flat shape with a length of approximately 633 mm to 972 mm in the first direction X, a height of approximately 100 mm to 150 mm in the second direction Y, and a width of approximately 30 mm to 34 mm in the third direction Z.

[0063] When the inner surface of the bottom plate 213 of the trough body 21 is oriented substantially upward (for example, in the second direction Y), the first side plate 211 and the second side plate 212 are arranged oriented in a direction rising from the bottom plate 213, for example, substantially upward. At this time, the trough body 21 forms an opening space Q whose interior opens substantially upward.

[0064] <Bottom plate 210> The base plate 210 refers to the plate that serves as the mounting surface for the trough body 21. The base plate 210 extends, for example, in the longitudinal direction.

[0065] The bottom plate 210 may have one or more first clamping portions 210a, each consisting of a pair of claws protruding toward the opening space Q on its inner surface, as shown in Figures 6 to 12. The first clamping portions 210a can, for example, clamp a known plate-shaped separator made of resin for separating the cables C1, C2, and C, thereby allowing the separator to be erected.

[0066] <First side plate 211> The first side plate 211 refers to the side plate that forms the retaining wall on the embankment side, among the two side plates that stand upright opposite each other from both ends of the base plate 210 in the width direction. The first side plate 211 is extended, for example, in the longitudinal direction.

[0067] The first side plate 211 may further have a fitting portion 211a at its upper end for fitting a resin extension side plate 23 that forms an earth retaining wall above it, as shown in Figures 6 to 12. In this case, the first side plate 211 is fitted to the extension side plate 23 by fitting the fitting portion 211a formed at its upper end with the fitting end portion 23a formed at the lower end of the extension side plate 23, as shown in Figures 10 to 12. In this case, the height of the opening space Q can be adjusted according to the number of cables C1, C2, and C by attaching and detaching the fitting portion 211a or by replacing fitting portions 211a of different heights, thereby reducing the amount of excavation required for the embankment. This improves the workability when installing the cable trough assembly 2. In the examples shown in Figures 10 to 12, a combination is illustrated in which the upper end of the first side plate 211 has a fitting portion 211a that recesses downward to form an insertion opening, and a fitting end portion 23a that protrudes so as to be insertable into the fitting portion 211a. However, the design is not limited to this, and a combination is also possible in which the lower end of the extension side plate 23 has a fitting end portion 23a that recesses upward to form an insertion opening, and a fitting portion 211a that protrudes so as to be insertable into the fitting end portion 23a. By providing the extension side plate 23 to the cable trough assembly 2 in this way, in addition to adjusting the height of the earth retaining section and the amount of excavation of the embankment, the height of the cable trough assembly 2 can be adjusted, thereby improving the efficiency of the construction work of the cable trough assembly 2. At the same time, it is possible to adjust the cable capacity, such as the type and number of cables.

[0068] The first side plate 211 may have a slit 211b formed at its upper end, as shown in Figures 11 and 12. This slit extends from a fitting portion 211a, which is recessed downwards and forms an insertion opening for the extension side plate 23, to the surface of the first side plate 211. In this case, any soil that has entered the fitting portion 211a or seepage water within the soil can be discharged. This improves the durability of the cable trough assembly 2. In addition to the above, providing the slit 211b not only allows for the drainage of seepage water, but also allows for slight elastic deformation of the area around the slit 211b when subjected to external stress, thereby mitigating the localized concentration of stress.

[0069] <Second side plate 212> The second side plate 212 refers to the side plate that is exposed to the track side, of the two side plates that stand upright opposite each other from both ends of the bottom plate 210 in the width direction. The second side plate 212 is also extended, for example, in the longitudinal direction. As shown in Figures 6 to 12, for example, the upper end of the second side plate 212 is lower than the upper end of the first side plate 211.

[0070] The second side plate 212 has a bolt hole 212a drilled at its upper end, as shown in Figures 4 and 8, for example, so that a retaining bracket 212b can be attached via a bolt (not shown). The retaining bracket 212b may be made of a metal plate, for example, and may have rigidity or elasticity like a leaf spring. The retaining bracket 212b presses each cable C1, C2, C downward, for example so that each cable C1, C2, C does not interfere with each other beyond the separator erected by the first side plate 211, the second side plate 212, and the first clamping part 210a. This improves the workability when installing the cable trough assembly 2.

[0071] <Cable holder 22> The cable support base 22 extends in the longitudinal direction (first direction X), as shown in Figures 4 and 5, for example, and is fitted into the trough body 21 and installed in the opening space Q. Figure 13 shows a side view of the cable support base 22 alone, and Figures 14 and 15 show a top view of the cable support base 22 alone.

[0072] The cable support base 22 has, for example, as shown in Figures 6 and 13, a fitting leg portion 221 that fits onto the upper end of the second side plate 212, and a base portion 222 that extends continuously from the fitting leg portion 221 toward the first side plate 211. The cable support base 22 may further have, for example, an upright leg portion 223 and a support leg portion 224 that extends downward from the lower surface of the base portion 222 and contacts the bottom plate 210. When the support leg portion 224 is provided, the cable support base 22 is supported from below by the support leg portion 224, making it less susceptible to damage from load. This improves the durability of the cable trough assembly 2. In addition, there is no need to fix the base portion 222 to the first side plate 211, eliminating the need for bolting and other such work. This improves the durability of the cable trough assembly 2. Furthermore, the cable support base 22 does not need to have support legs 224 if it is supported from the second side plate 212 via fitting legs 221 to such an extent that the base portion 222 can be sufficiently supported from below. Alternatively, the cable support base 22 may be supported from the first side plate 211 by being fixed to the first side plate 211. As for the material of the cable support base 22, from the viewpoint of ease of installation work, a lightweight and cuttable resin material is used rather than steel or concrete.

[0073] The dimensions of the cable support base 22 are as follows: for example, the fitting leg portion 221 has a shape in which two flat plates face each other, with a length of approximately 100 mm to 253 mm in the first direction X, a height of approximately 220 mm in the second direction Y, and a width of approximately 13 to 19 mm in the third direction Z; the base portion 222 has a roughly flat shape with a length of approximately 100 mm to 253 mm in the first direction X, a height of approximately 20 mm in the second direction Y, and a width of approximately 500 mm in the third direction Z; the upright leg portion 223 has a roughly flat shape with a length of approximately 100 mm to 253 mm in the first direction X, a height of approximately 120 mm in the second direction Y, and a width of approximately 15 mm in the third direction Z; and the support leg portion 224 has a roughly flat shape with a length of approximately 100 mm to 253 mm in the first direction X, a height of approximately 220 mm in the second direction Y, and a width of approximately 13 to 19 mm in the third direction Z.

[0074] The cable support base 22 is installed within the opening space Q, thereby dividing the opening space Q into an upper space Q1 and a lower space Q2 via the base portion 222 in at least a portion of the cross-section of the cable trough assembly 2. In this case, by installing cables C1, C2, and C in the upper space Q1 and lower space Q2, respectively, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. Specifically, for example, physical interference between cables C1, C2, and C, and interference due to electrical noise caused by induced current can be suppressed. Furthermore, it becomes possible to arrange cables on the cable support base 22 in a way that takes into account the purpose, use, type, and number of cables, as well as ease of work. In addition, the cable accommodation efficiency of the cable accommodation space formed by the cable trough assembly 2 can be improved. As a result, the workability during installation and the manageability after installation of platform door cables C1, C2, and C can be improved.

[0075] When the inner surface of the bottom plate 210 of the cable support base 22 is oriented substantially upward (for example, in the second direction Y), the fitting legs 221 are oriented substantially vertically, and the base portion 222 is oriented in the width direction (for example, in the third direction Z). At this time, within the opening space Q, an upper space Q1 is formed above the base portion 222, and a lower space Q2 is formed below the base portion 222.

[0076] The cable support base 22 may have a length in the longitudinal direction (e.g., first direction X) shorter than the trough body 21, as shown in Figure 4, for example. In this case, many cable wiring patterns can be applied using the upper space Q1 and lower space Q2, which are divided within the opening space Q via the base portion 222. Furthermore, it is easier to secure working space for workers in areas where the cable support base 22 is not present. That is, the same working space as when the cable support base 22 is not installed can be secured with only the trough body 21, significantly improving the workability of cable wiring and laying work. In addition, the arrangement of cables on adjacent cable support bases can be optimized according to the purpose, use, type, and number of cables used. This makes it possible to further improve the workability during installation and the manageability after installation for platform door cables C1, C2, and C.

[0077] In the example shown in Figures 4 and 5, three cable supports 22A, 22B, and 22C are spaced apart from each other and fitted into a single trough body 21. Here, there is no cable support 22 between cable supports 22A and 22B, and the upper space Q1 and the lower space Q2 are in communication (see Figure 6 showing the CC cross section of Figure 4). Similarly, there is no cable support 22 between cable supports 22B and 22C, and the upper space Q1 and the lower space Q2 are in communication (see Figure 8 showing the EE cross section of Figure 4). In this case, the worker can route cables C1, C2, and C through the space between cable supports 22A and 22B, or between cable supports 22B and 22C. Furthermore, by inserting a hand or tool, cables C1, C2, and C can be easily installed in the upper space Q1 and the lower space Q2. Figure 14 shows a plan view of cable support 22A, and Figure 15 shows plan views of cable support 22B and 22C, respectively. The longitudinal length of cable support 22A may be longer than that of cable support 22B and 22C, as shown in Figures 14 and 15, and may be set arbitrarily.

[0078] <Matching leg portion 221> The fitting leg portion 221 is fitted to the upper end of the second side plate 212 of the trough body 21. The fitting leg portion 221 extends, for example, in the longitudinal direction.

[0079] The fitting leg portion 221 has a roughly inverted U-shaped cross-section that protrudes upward from its lower end, as shown in Figures 6 to 8 and Figure 13, for example, and is fitted by clamping the upper end of the second side plate 212. Alternatively, the fitting leg portion 221 may have a protruding shape that can be inserted into the second side plate 212, which has a shape that protrudes downward from its upper end, and may be inserted into or clamped onto the upper end of the second side plate 212 for fitting.

[0080] <Base part 222> The base portion 222 extends continuously from the fitting leg portion 221 toward the first side plate 211. The base portion 222 extends, for example, in the longitudinal direction. The base portion 222 may be in contact with the first side plate 211 or may be spaced apart from it.

[0081] When the cable support base 22 is installed in the opening space Q of the trough body 21, the base portion 222 divides the opening space Q into an upper space Q1 and a lower space Q2. At this time, the base portion 222 separates from the bottom plate 210, thereby forming the lower space Q2 between itself and the bottom plate 210. Note that the division of the opening space Q as referred to here means that the cable trough assembly 2 is divided into multiple spaces in at least some cross-sections, and does not have to be divided in other cross-sections. Furthermore, the division of the opening space Q also includes the case in the cross-section where the base portion 222 is located, where the base portion 222 separates from the first side plate 211, resulting in a division on the second side plate 212 side but not on the first side plate 211 side.

[0082] The base portion 222 is, for example, continuous with the upper end of the fitting leg portion 221. The base portion 222 may protrude at any position on the surface of the fitting leg portion 221 on the lower space Q2 side, as long as it is spaced apart from the bottom plate 210.

[0083] The base portion 222 may have, for example, one or more second clamping portions 222a on the surface facing the upper space Q1, each consisting of a pair of claws protruding toward the upper space Q1. The second clamping portions 222a can, for example, clamp the separators described above for separating the cables C1, C2, and C, thereby enabling the separators to be erected.

[0084] The base portion 222 may have ribs 222b provided on the surface of the upper space Q1 side or the lower space Q2 side by corrugation or the like, as shown in Figure 13, for example. In other words, the base portion 222 is reinforced by the ribs 222b. In this case, the number of support legs 224 that could interfere with the cables C1, C2, and C can be reduced. That is, even when using the cable support base 22, there is no need to provide support legs 224 under the base portion 222, so a wider working space can be secured compared to when support legs 224 are provided, and the cable wiring and laying work is greatly improved. As a result, the workability during installation and the manageability after installation of the platform door cables C1, C2, and C can be further improved.

[0085] The base portion 222 may have a notch 222c formed on its surface, for example, as shown in Figures 13 to 14. The notch 222c connects the upper space Q1 and the lower space Q2. In this case, by routing the cables C1, C2, and C through the notch 222c, the vertical wiring of cables C1, C2, and C can be easily carried out. This further improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. Also, as shown in Figure 14, by providing a notch 222c of a predetermined width only in the center of the longitudinal direction (first direction X) of the cable support base 22, the vertical wiring of cables from the lower space Q2 to the upper space Q1 through the notch 222c of the cable support base 22 can be easily carried out. Furthermore, since the cable support base 22 is provided with support legs 224 on both sides of the notch 222c, sufficient strength of the cable support base 22 can be ensured even with the notch 222c.

[0086] The base portion 222 may have, for example, one or more band perforations 222h. By passing known cable tie bands through the band perforations 222h, the operator can secure the cables C1, C2, and C installed in the upper space Q1 or lower space Q2 to the surface of the base portion 222.

[0087] <Standing leg section 223> The upright legs 223 refer to one or more side plates that rise up toward the upper space Q1 from the surface of the base portion 222 on the upper space Q1 side, as shown in Figures 6 to 8 and Figure 13, for example. The upright legs 223 extend, for example, in the longitudinal direction. The upright legs 223 prevent cables C1, C2, and C installed in the upper space Q1 from protruding toward the track side or falling.

[0088] The upright legs 223 divide the upper space Q1 into one upper space Q1a and the other upper space Q1b, as shown in Figures 13 and 14, for example. In this case, by installing cables C1, C2, and C in the one upper space Q1a and the other upper space Q1b respectively, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0089] Here, the base portion 222 may have a notch 222c that connects the upper other space Q1b and the lower space Q2. In this case, interference between the cable routing wiring, which raises the cables C1 and C2 stored in the lower space Q2 upwards and passes through the upper other space Q1b, and the wiring of cable C stored in the upper one space Q1a can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0090] <Support leg 224> The support legs 224 refer to one or more side plates that rise from the surface of the base portion 222 on the lower space Q2 side toward the lower space Q2, as shown in Figures 6 to 8 and Figure 13, for example. The support legs 224 extend, for example, in the longitudinal direction. By supporting the base portion 222 from below, the support legs 224 suppress deformation of the base portion 222 even after cables C1, C2, and C are installed in the upper space Q1, and maintain the lower space Q2 from shrinking.

[0091] The support legs 224 are locked or fixed to, for example, the bottom plate 210 or the first side plate 211 by contact. The support legs 224 may have any shape that can support the base portion 222.

[0092] <Extension side plate 23> The extension side plate 23 is made of a resin plate that serves as a retaining wall. The extension side plate 23 is fitted into the fitting portion 211a and installed above the first side plate 211, as shown in Figures 4 to 8 and 10 to 12.

[0093] The extension side plate 23 has, for example, a fitting end 23a. The extension side plate 23 is fitted into the trough body 21 by fitting the fitting end 23a into the fitting portion 211a. The shape of the fitting end 23a may be, for example, a comb-like shape as shown in Figure 11.

[0094] The dimensions of the extension side plate 23 are, for example, a roughly flat shape with a length of approximately 633 mm to 967 mm in the first direction X, a height of approximately 310 mm in the second direction Y, and a width of approximately 25 mm in the third direction Z.

[0095] (Installation method for platform screen door cable installation structure 1) Next, the installation method for the platform door cable installation structure 1 (installation method for platform door cables C1, C2, and C) will be explained. The installation method for platform door cables C1, C2, and C involves first performing the cable installation process, which includes an assembly process and a trough installation process, for the cable trough assembly 2. In other words, the installation method for platform door cables C1, C2, and C includes an assembly process, a trough installation process, and a cable installation process.

[0096] <Preparation> Before carrying out the cable trough installation process, workers excavate the embankment that constitutes the platform foundation F11 along the outer edge on the track side, as shown in Figures 1 to 3, for example, to pre-form the excavation space. At this stage, the cable trough assembly 2, the end tiles 14, and the platform doors 11 and 12 have not yet been installed.

[0097] <Assembly Process> In the assembly process, the worker fits a resin cable support base 22 into a resin trough body 21, which has an opening space Q formed therein, having a second side plate 212 lower than the upper end of the first side plate 211, thereby assembling one or more cable trough assemblies 2 as shown in Figures 4 to 8. Here, since the cable trough assemblies 2 can be assembled without using fasteners such as bolts, work efficiency can be improved compared to conventional troughs that use fasteners.

[0098] <Trough installation process> In the trough installation process, workers install the cable trough assembly 2, assembled in the assembly process, into an excavated space pre-formed below the planned installation locations of the platform doors 11 and 12, with the inner surface of the bottom plate 210 of the trough body 21 facing approximately upward (for example, in the second direction Y), and with the second side plate 212 exposed to the track side, as shown in Figures 1 and 2. In this case, by installing cables C1, C2, and C from the track side into the upper space Q1 and the lower space Q2, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. At this time, the first side plate 211 and the extension side plate 23 are installed on the platform side and function as retaining walls for the platform foundation F11. In this case, by optimizing the height of the extension side plate 23, the amount of soil excavated and discharged from the platform foundation F11 can be optimized, making it possible to carry out construction work in accordance with the site conditions, thus improving the efficiency of the construction work.

[0099] Here, the outer surfaces of the first side plate 211, the second side plate 212, and the bottom plate 213 are not provided with grooves or protrusions for fitting with other adjacent cable troughs. In this case, it can be installed by inserting it into the excavation space from the track side in a substantially horizontal direction (for example, the third direction Z). That is, compared to cable troughs that are fitted in a vertical direction (for example, the second direction Y), there is no need to insert it into the excavation space from above downwards, so workers can easily install the cable trough assembly 2 from the track side without creating scaffolding. In this case, there is no risk of falling from the platform foundation F11 or scaffolding, improving the safety and work efficiency of the installation work. As described above, since the cable trough assembly 2 does not have a connecting structure that is dropped in from above to connect, the troughs do not need to be connected to each other. Instead, the ends of adjacent troughs are brought close to or in contact with each other, the first side plate 211 is placed on the platform side, the second side plate 212 faces the track side, and the trough body 21 is continuously placed from the platform side, making the construction easy.

[0100] In addition, along with the cable trough assembly 2, a cable trough assembly 2' consisting only of the trough body 21' that has not been assembled during the assembly process is also installed, for example, as shown in Figures 1, 3, and 9. In the example in Figure 1, after the platform door cables C1 and C2 are raised and connected toward the platform door 11, the cable trough assembly 2' is installed to secure a cable route for installing the platform door cables C1 and C2 toward the platform door 12. This allows the trough body 21 and 21', which are the same components, to be used interchangeably according to the required cable route size. This improves the cost-effectiveness of the installation of the platform door cables C1, C2, and C.

[0101] After repeating the above procedure to install a predetermined number of cable trough assemblies 2 and 2', the end tiles 14, platform doors 11 and 12, and partition walls 13 are installed above the cable trough assemblies 2 and 2'. Note that the installation of the end tiles 14, platform doors 11 and 12, and partition walls 13 may be carried out after the installation of platform door cables C1, C2, and C in the cable installation process.

[0102] <Cable Installation Process> In the cable installation process, workers install multiple platform door cables C1, C2, and C from the track side so that they pass through the upper space Q1 and lower space Q2 of the cable trough assembly 2, which was installed in the trough installation process (installation method for cable trough assembly 2). In this case, by installing cables C1, C2, and C from the track side in the upper space Q1 and lower space Q2 respectively, interference between cables C1, C2, and C can be suppressed. Specifically, for example, physical interference between cables C1, C2, and C, and interference due to electrical noise caused by induced current can be suppressed. This improves the workability during installation and the manageability after installation of platform door cables C1, C2, and C. Here, since the cable trough assembly 2 is divided into an upper space Q1 and a lower space Q2 by the cable support base 22, the cables to be used for platform doors can be placed in appropriate positions above and below the cable support base 22 in the trough, according to their type and purpose, while also considering the workability during cable laying.

[0103] As shown in Figures 2 and 4, for example, in the area where the cable trough assembly 2 is installed, the worker inserts their hands or tools from the track side into the space between cable supports 22A and 22B (first space) or between cable supports 22B and 22C (second space) to install the platform door cables C1, C2, and C in the upper space Q1 and lower space Q2, respectively. Specifically, the worker inserts their hand into the first space, for example, to pick up the platform door cables C1, C2, and C stored in the upper space Q1 or lower space Q2 of the cable trough assembly 2, and passes them to their hand inserted into the adjacent second space. This process is repeated until the platform door cables C1, C2, and C pass through the upper space Q1 or lower space Q2 of the cable trough assembly 2. In this way, by setting the space for passing cables in the space between cable receiving stands 22 where no cable receiving stands 22 are placed, tasks such as passing cables become easier, and the efficiency of cable passing work is improved.

[0104] Furthermore, as shown in Figure 3, for example, in the area where the cable trough assembly 2' is installed, the worker inserts their hand or tools from the track side into the opening space Q exposed to the track side and, while holding the platform door cables C1, C2, and C stored in the opening space Q, pulls them up in the longitudinal direction of the cable trough assembly 2 (for example, the first direction X), thereby installing the platform door cables C1, C2, and C so that they pass through the opening space Q of the cable trough assembly 2.

[0105] By carrying out the above steps, the installation method for platform screen door cables C1, C2, and C is completed.

[0106] As described above, the installation method for platform screen door cables C1, C2, and C completely separates the trough installation process from the cable installation process. In this case, wiring work can be carried out independently of civil engineering work. This improves the work efficiency of cable installation work. In addition, it makes it easier to carry out additional work or repairs on platform screen door cables C1, C2, and C.

[0107] Furthermore, after the installation of platform door cables C1, C2, and C is completed, workers can visually inspect the appearance of the platform door cables C1, C2, and C stored in the cable trough assembly 2 without having to perform any work from the track side. This improves the manageability of platform door cables C1, C2, and C after installation.

[0108] (First modified example of installation structure 1 for platform screen door cables) The cable trough assembly 2 may be constructed, for example, by assembling a cable trough assembly set for platform screen doors.

[0109] The cable trough assembly set for platform screen doors comprises a resin U-shaped trough body (not shown) having a substantially U-shaped opening space Q with a cross-section having a second side plate 212 that is substantially the same height as the first side plate 211, and a resin cable support base 22 having a base portion 222 that extends toward the first side plate 211 from a fitting leg portion 221 that fits onto the upper end of the second side plate 212, which has been cut from the upper end by a predetermined length so as to be lower than the upper end of the first side plate 211. In this way, even when using a resin U-shaped trough body with a substantially U-shaped cross-section where the first side plate 211 and the second side plate 212 are substantially the same height, by cutting the second side plate 212 to a predetermined height and combining the trough body 21 with the cut second side plate 212 with the resin cable support base 22, the same effect as when using a trough body 21 in which the height of the second side plate 212 is set lower than the height of the first side plate 211 can be obtained.

[0110] Here, the U-shaped trough body is formed by cutting the second side plate 212 by a predetermined length from the upper end so that it is lower than the upper end of the first side plate 211. In other words, by using the platform door cable trough assembly set, a cable trough assembly 2 can be constructed, which includes the trough body 21 and a cable support base 22 that fits onto the upper end of the second side plate 212. In this case, by installing cables C1, C2, and C in the upper space Q1 and lower space Q2, respectively, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. In addition, the height of the upper space Q1 and the lower space Q2 can be adjusted according to the number of cables C1, C2, and C. This improves the convenience of installation of the platform door cables C1, C2, and C. In this assembly set, a trough body 21 is formed by cutting, in which the height of the second side plate 212 is set lower than the height of the first side plate 211. Furthermore, by using a trough body 21 and cable support base 22 in which the height of the second side plate 212 is formed lower than the height of the first side plate 211 by cutting, the same effect as the trough body 21 of the present invention, in which the height of the second side plate 212 is formed lower than the height of the first side plate 211, can be obtained.

[0111] Furthermore, the platform door cable trough assembly set comprises a resin U-shaped trough body (not shown) having a substantially U-shaped opening space Q with a cross-section having a second side plate 212 at substantially the same height as the first side plate 211, a resin extension side plate 23 fitted above the first side plate 211 so as to be higher than the upper end of the second side plate 212 to form a retaining wall, and a resin cable support base 22 having a base portion 222 that extends toward the first side plate 211 from a fitting leg portion 221 fitted to the upper end of the second side plate 212.

[0112] Here, the U-shaped trough body is formed by fitting the extension side plate 23 above the first side plate 211 so that it is higher than the upper end of the second side plate 212, thereby becoming the trough body 21 described above. In this case, by installing cables C1, C2, and C in the upper space Q1 and lower space Q2, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. In addition, the height of the upper space Q1 and the lower space Q2 can be adjusted according to the number of cables C1, C2, and C. This improves the convenience of installation of the platform door cables C1, C2, and C. In this assembly set, the height of the first side plate 211 can be adjusted in addition to the second side plate 212, allowing for the configuration of the cable trough assembly 2 according to the purpose, use, type, and number of cables used for platform doors. This expands the range of adaptability for construction and cable placement according to the construction site and usage conditions.

[0113] (Installation method for the first modified example of the installation structure 1 for platform screen door cables) <Assembly Process> In the assembly process, the worker forms the resin trough body 21 by cutting the second side plate 212 (the other side plate) from the top end to a predetermined length so that it is lower than the top end of the first side plate 211 (one side plate). Since the worker can easily cut the U-shaped trough body to form the trough body 21 using, for example, a known electric saw or circular saw, the work efficiency is higher compared to when using troughs made of steel or concrete.

[0114] Subsequently, the worker cuts the second side plate 212 to form a trough body 21, and then fits a resin cable support base 22 onto it to assemble one or more cable trough assemblies 2, such as those shown in Figures 4 to 8. In this case, the height of the upper space Q1 and the lower space Q2 can be adjusted according to the number of cables C1, C2, and C. This improves the convenience of installation for the platform door cables C1, C2, and C.

[0115] Alternatively, the worker may form the trough body 21 by fitting a resin extension side plate 23 above the first side plate 211 (one side plate) so that it is higher than the upper end of the second side plate 212 (the other side plate). In this case, it is not necessary to cut the U-shaped trough, which improves work efficiency compared to when the U-shaped trough is cut.

[0116] Subsequently, the worker fits the resin cable support base 22 onto the trough body 21 formed by fitting the extension side plate 23, and assembles one or more cable trough assemblies 2 as shown in Figures 4 to 8. In this case, the height of the upper space Q1 and the lower space Q2 can be adjusted according to the number of cables C1, C2, and C. This improves the convenience of installation for platform door cables C1, C2, and C. Here, this assembly set can be made by either fitting the extension side plate 23 above the first side plate 211 to raise the height, or by cutting the second side plate 212, so it has a wide range of applicability and requires fewer trough molds, thus improving cost-effectiveness. Furthermore, by using the cable support base 22, the cable storage capacity can be increased, making it easier to arrange cables according to their purpose, use, type, and number, and by using the extension side plate 23 in combination, the space for laying work is expanded, making cable laying work easier.

[0117] (Second modified example of installation structure 1 for platform screen door cables) The cable trough assembly 2 may further have a movable housing portion 225 in the cable support base 22, as shown in Figure 16, for example. Figure 16 shows a schematic cross-sectional view of the cable trough assembly 2 of this modified example.

[0118] The movable housing portion 225 is provided on the base portion 222 and is slidable on the base portion 222 in the width direction (for example, the third direction Z). The movable housing portion 225 extends, for example, in the longitudinal direction. The movable housing portion 225 is, for example, a hollow box, has a substantially U-shaped cross-section that opens in the longitudinal direction (for example, the first direction X) and upward, and has an upper one-sided space Q1a (upper space Q1).

[0119] Workers can pull out the movable housing 225 from the track side in the direction of the arrow shown in Figure 16 and install cables C1, C2, and C inside the movable housing 225. In this case, by pulling out the movable housing 225 towards the track side, the wiring of cables C1, C2, and C installed inside and their visual inspection after installation can be reliably carried out. This further improves the workability during installation and the manageability after installation of platform door cables C1, C2, and C. In addition, by pulling out the movable housing 225 and bringing its housing position closer to the track side, the work of storing and laying the cables in the movable housing 225 becomes easier, improving the efficiency of cable laying work. Furthermore, the position of the movable housing 225 within the trough can be changed as needed before and after construction, improving convenience.

[0120] The movable housing section 225 may, for example, have a resin separator 225a erected on top (for example, in the second direction Y) inside. In this case, the upper one-sided space Q1a inside the movable housing section 225 is divided into multiple upper one-sided spaces Q1a, Q1a', which further suppresses interference between cables C1, C2, and C, and further improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. Here, since the arrangement of the cables is divided by the separator 225a, the arrangement can be separated according to the purpose and use of the cables, making cable management easier.

[0121] The movable housing section 225 may be spaced apart from, for example, the first side plate 211 and the extension side plate 23, forming a spaced-out area (upper other space Q1b) between the outer surface of the box and the first side plate 211 and the extension side plate 23. In this case, the base section 222 may have a notch 222c formed on its surface that connects the spaced-out area and the lower space Q2. In this case, by routing the cables C1, C2, and C through the notch 222c, the vertical wiring of cables C1, C2, and C can be easily carried out. This further improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0122] (Third modified example of installation structure 1 for platform screen door cables) The cable trough assembly 2 may further have support legs 224' in the cable support base 22, as shown in Figure 17, for example. Figure 17 shows a schematic cross-sectional view of the cable trough assembly 2 of this modified example.

[0123] The support legs 224' are spaced apart from the first side plate 211 and extend downward from the lower surface of the base portion 222, contacting the bottom plate 210, thus distinguishing them from the support legs 224 that contact the first side plate 211. In this case, the lower space Q2 is divided into one lower space Q2a and the other lower space Q2b by the support legs 224' in at least a portion of the cross-section of the cable trough assembly 2. In this case, by installing cables C1, C2, and C in the one lower space Q2a and the other lower space Q2b, respectively, which are divided within the lower space Q2 via the support legs 224', interference between cables C1, C2, and C can be further suppressed. This makes it possible to further improve the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. In addition, the cable support base 22 is less likely to be damaged by load. This makes it possible to improve the durability of the cable trough assembly 2. In this way, the space formed by the base portion 222 and the support leg portion 224 can be divided on the lower side of the base portion 222 by providing another support leg portion 224', making it easier to categorize the cables placed on the lower side of the base portion 222 according to their purpose and type, and improving the strength of the cable support base 22.

[0124] (Fourth modified example of installation structure 1 for platform screen door cables) The cable trough assembly 2 may further include an extension side plate 23 with cable holes 23b drilled on its surface, as shown in Figures 18 and 19. Figure 18 shows a schematic front view of the cable trough assembly 2 of this modified example, and Figure 19 shows a schematic cross-sectional view of the installation structure 1 for platform door cables using the cable trough assembly 2 shown in Figure 18.

[0125] The installation structure 1 for platform screen door cables includes a wireless platform screen door interoperation system. The wireless platform screen door interoperation system is a system that uses wireless equipment and various sensors installed on racks attached to the platform roof or the like above the platform screen doors 11 and 12 to communicate with the wireless equipment of a train stopped on the platform. When communicating, for example, a general-purpose wireless device in the UHF band is used to read RFID (registered trademark) tags or QR codes (registered trademark) attached to the train to be interoperated in order to obtain train formation information and identify the interoperating partner. The wireless platform screen door interoperation system has multiple wireless interoperation cables C3 and C4, which include cables that serve as signal transmission paths and power supply paths to electrically connect the aforementioned devices included in the configuration. In other words, the installation structure 1 for platform screen door cables including the wireless platform screen door interoperation system requires the installation of wireless interoperation cables C3 and C4 separately from the platform screen door cables C1, C2 and C.

[0126] The extension side plate 23 is provided with cable holes 23b in the width direction (for example, the third direction Z) for inserting wireless communication cables C3 and C4, as shown in Figure 18, for example.

[0127] The installation structure 1 for the platform screen doors further comprises, for example, a plurality of wireless communication cables C3 and C4, and a hollow rising guide pipe 3 having an internal space, which is pre-disposed between the platform base F11 and the platform surface layer F12.

[0128] The riser guide pipe 3 is made of, for example, a resin pipe or a steel pipe and extends from the outer edge on the track side toward the platform side. The riser guide pipe 3 is installed by extending it in a direction perpendicular to the extension direction of the embankment-type platform (for example, the third direction Z).

[0129] In this installation structure 1 for platform doors, wireless communication cables C3 and C4 are routed through the upper space Q1, the cable hole 23b, and the internal space of the riser guide conduit 3, and are raised near the existing platform pillars 15 that are pre-erected on the platform side of the platform surface F12. In this case, for the multiple wireless communication cables C3 and C4 that are routed above the platform doors 11 and 12, two routes can be secured: one that passes through the cable hole 23b from the opening space Q of the trough body 21 and rises around the platform pillars 15, and another that runs along the platform pillars 15 and connects to equipment above the platform doors 11 and 12. This ensures that the multiple wireless communication cables C3 and C4 do not interfere with the operation of the platform doors 11 and 12. Furthermore, they are less likely to interfere with the cable routes of the platform door cables C1 and C2 (dashed line area in Figure 19). This improves the workability during installation and the manageability after installation for the multiple wireless communication cables C3 and C4. Furthermore, the provision of cable holes 23b facilitates the extraction of cables from the cable trough assembly 2, allowing for stable cable extraction, while also enabling the extension side plate 23 to function as a retaining wall for the embankment.

[0130] (Installation method for the fourth modified example of installation structure 1 for platform screen doors) <Trough installation process> In the trough installation process, the worker installs the riser guide pipe 3 between the platform foundation F11 and the platform surface F12, oriented in the third direction Z, and then installs the cable trough assembly 2 in the excavated space pre-formed below the platform doors 11 and 12. At this time, the worker installs the riser guide pipe 3 so that the pre-drilled cable insertion holes in the platform surface F12, the internal space of the riser guide pipe 3, and the cable holes 23b and upper space Q1 of the extension side plate 23 are in communication with each other. The platform surface F12, the riser guide pipe 3, and the extension side plate 23 may be fitted and fixed to each other.

[0131] <Cable Installation Process> In the cable installation process, workers install multiple wireless communication cables C3 and C4 from the track side so that they pass through the upper space Q1 of the cable trough assembly 2 installed in the trough installation process, the cable holes 23b, the internal space of the riser guide pipe 3, and the perforations for cable insertion pre-drilled in the platform surface F12. In this case, the multiple wireless communication cables C3 and C4 do not interfere with the operation of the platform doors 11 and 12. This improves the workability during installation and the manageability after installation of the multiple wireless communication cables C3 and C4.

[0132] According to this embodiment, the platform door cable trough assembly 2 comprises a resin trough body 21 having an opening space Q formed therein, which has a second side plate 212 lower than the upper end of the first side plate 211, and a resin cable support base 22 having a base portion 222 that extends continuously toward the first side plate 211 from a fitting leg portion 221 that fits onto the upper end of the second side plate 212. Therefore, by installing cables C1, C2, and C in the upper space Q1 and lower space Q2, respectively, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. Furthermore, since the trough body 21 and cable support base 22 are made of resin, they can be easily cut on-site to adjust their height. This improves the workability during installation of the platform door cables C1, C2, and C.

[0133] Furthermore, according to this embodiment, the trough body 21 further has a fitting portion 211a into which a resin extension side plate 23 that forms an earth retaining wall is fitted above the first side plate 211. Therefore, the height of the opening space Q can be adjusted according to the number of cables C1, C2, and C, and the amount of excavation of the embankment can be reduced. This improves the workability when installing the platform door cable trough assembly 2.

[0134] Furthermore, according to this embodiment, the trough body 21 has a slit 211b formed in it that penetrates from the fitting portion 211a, which is recessed downward at the upper end of the first side plate 211, to the surface of the first side plate 211. This allows for the discharge of embankment soil and seepage water from within the embankment that has entered the fitting portion 211a. This improves the durability of the cable trough assembly 2 for platform doors.

[0135] Furthermore, according to this embodiment, an extension side plate 23 is provided, which has a cable hole 23b for inserting wireless communication cables C3 and C4. As a result, for wireless communication cables C3 and C4 that are routed above the platform doors 11 and 12, two routes can be secured: one that passes through the cable hole 23b from the opening space Q of the trough body 21 and rises up around the platform pillar 15, and another that runs along the platform pillar 15 and connects to equipment above the platform doors 11 and 12. This ensures that wireless communication cables C3 and C4 do not interfere with the operation of the platform doors 11 and 12. This improves the workability during installation and the manageability after installation of wireless communication cables C3 and C4.

[0136] Furthermore, according to this embodiment, the cable support base 22 is provided with ribs 222b on the base portion 222. That is, the base portion 222 is reinforced by the ribs 222b. As a result, the number of support legs 224 that may interfere with cables C1, C2, and C can be reduced. This makes it possible to further improve the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0137] Furthermore, according to this embodiment, the cable support base 22 has a notch 222c formed in the base portion 222 that connects the upper space Q1 and the lower space Q2. Therefore, by routing the cables C1, C2, and C through the notch 222c, the vertical wiring of cables C1, C2, and C can be easily carried out. This makes it possible to further improve the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0138] Furthermore, according to this embodiment, the cable support base 22 has a shorter longitudinal length than the trough body 21. Therefore, many cable wiring patterns can be applied using the upper space Q1 and lower space Q2, which are divided within the opening space Q via the base portion 222. In addition, it is easier to secure working space for workers in areas where the cable support base 22 is not present. As a result, the workability during installation and the manageability after installation of the platform door cables C1, C2, and C can be further improved.

[0139] Furthermore, according to this embodiment, the cable support base 22 further has a movable housing portion 225 that is slidable in the width direction on the base portion 222. Therefore, by pulling the movable housing portion 225 towards the track side, the wiring of cables C1, C2, and C installed inside and their visibility after installation can be reliably carried out. This makes it possible to further improve the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0140] Furthermore, according to this embodiment, the cable support base 22 has support legs 224' that extend downward from the lower surface of the base portion 222 and contact the bottom plate 210. Therefore, the cable support base 22 is less likely to be damaged by load. This improves the durability of the platform door cable trough assembly 2. Also, there is no need to fix the base portion 222 to the first side plate 211, eliminating the need for bolting and other such work. This improves the durability of the platform door cable trough assembly 2. In addition, when the support legs 224' are provided spaced apart from the first side plate 211, the cables C1, C2, and C can be installed in the lower one space Q2a and the lower other space Q2b, respectively, which are divided in the lower space Q2 via the support legs 224', thereby further suppressing interference between the cables C1, C2, and C. This further improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0141] Furthermore, according to this embodiment, the platform door cable trough assembly set comprises a resin U-shaped trough body having a substantially U-shaped opening space Q with a cross-section having a second side plate 212 that is substantially the same height as the first side plate 211, and a resin cable support base 22 having a base portion 222 that extends toward the first side plate 211 from a fitting leg portion 221 that fits onto the upper end of the second side plate 212 which is cut from the upper end by a predetermined length so as to be lower than the upper end of the first side plate 211. As a result, by installing cables C1, C2, and C in the upper space Q1 and lower space Q2, respectively, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. In addition, the height of the upper space Q1 and the lower space Q2 can be adjusted according to the number of cables C1, C2, and C. This will improve the convenience of installation for platform screen door cables C1, C2, and C.

[0142] Furthermore, according to this embodiment, the platform door cable trough assembly set comprises a resin U-shaped trough body having a substantially U-shaped opening space Q with a cross-section having a second side plate 212 at substantially the same height as the first side plate 211, a resin extension side plate 23 fitted above the first side plate 211 so as to be higher than the upper end of the second side plate 212 to form a retaining wall, and a resin cable support base 22 having a base portion 222 that extends toward the first side plate 211 from a fitting leg portion 221 fitted to the upper end of the second side plate 212. Therefore, by installing cables C1, C2, and C in the upper space Q1 and lower space Q2, respectively, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C. Furthermore, the height of the upper space Q1 and the lower space Q2 can be adjusted according to the number of cables C1, C2, and C. This improves the convenience of installation for platform screen door cables C1, C2, and C.

[0143] Furthermore, according to this embodiment, the cable support base 22 has a resin fitting leg portion 221 that fits onto the upper end of the second side plate 212 of the platform door cable trough assembly 2, and a resin base portion 222 that extends continuously from the fitting leg portion 221 toward the first side plate 211. Therefore, by installing cables C1, C2, and C in the upper space Q1 and the lower space Q2, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0144] Furthermore, according to this embodiment, the installation structure of the platform door cable trough assembly 2 comprises the platform door cable trough assembly 2, and the trough body 21 is installed with the inner surface of the bottom plate 210 oriented substantially upward and the second side plate 212 exposed to the track side. Therefore, by installing cables C1, C2, and C in the upper space Q1 and lower space Q2, which are divided within the opening space Q via the base portion 222, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0145] Furthermore, according to this embodiment, the installation structure 1 for platform door cables comprises a platform door cable trough assembly 2 and a plurality of platform door cables C1, C2, and C installed in the upper space Q1 and the lower space Q2, respectively. The trough body 21 is installed with the inner surface of the bottom plate 210 oriented substantially upward and the second side plate 212 exposed to the track side. Therefore, by installing cables C1, C2, and C from the track side in the upper space Q1 and the lower space Q2, respectively, interference between cables C1, C2, and C can be suppressed. This improves the workability during installation and the manageability after installation of the platform door cables C1, C2, and C.

[0146] Furthermore, according to this embodiment, the installation method for the platform door cable trough assembly 2 includes an assembly step of assembling the platform door cable trough assembly 2 by fitting a resin cable support base 22 into a resin trough body 21 in which an opening space Q is formed, having a second side plate 212 that is lower than the upper end of the first side plate 211; and a trough installation step of installing the platform door cable trough assembly 2 in the space formed below the platform doors 11 and 12, with the inner surface of the bottom plate 210 oriented substantially upward and the second side plate 212 exposed to the track side.
