Description

【Technical Field】 【0001】 The present invention relates to a platform substructure member used on a platform of a railway station and a platform substructure using the same. 【Background Art】 【0002】 Cables may be laid below the platform. In particular, in recent years, platform doors have been increasingly installed on platforms, and cables are laid under the platform on the edge side of the platform for power supply and control of the platform doors. 【0003】 As a laying structure for such platform door cables, for example, a cable trough is installed under the platform, and a platform door cable laying structure with an open side wall exposed to the track side has been proposed (for example, Patent Document 1). 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2017-17801 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 However, in the structure such as Patent Document 1 in the prior art, it is necessary to lay precast concrete slabs on the housing part and the passage part located above the cable cabinet. At this time, since the H-shaped steel is arranged entirely to support the precast concrete slab, the number of members increases and the construction process becomes complicated. As a result, there is a problem that the construction time is prolonged. 【0006】 A predetermined standard value is set for the distance between the tracks and the end of the platform (the so-called gap between the platform and the train). However, when the tracks at the end of the platform are located in a curved section, the gap dimension changes because the tracks move closer to the platform on an inner curve and move away on an outer curve. Conventional structures have the problem of not being able to flexibly adjust this gap. For example, platform doors and tactile paving are installed at the edge of the platform as a safety measure for passengers, but the position of these tiles is determined based on the distance from the center of the tracks to the end of the platform. Therefore, if the position of the tiles needs to be changed, it is necessary to redo the installation of the troughs and precast concrete slabs, which are the foundation of the platform structure, and this places a significant burden on terms of constructability and cost. 【0007】 This invention has been made in view of the above problems, and aims to provide a platform substructure member that has a simple structure that does not require precast concrete slabs or H-shaped steel beams to support the precast concrete slabs in the passageway, and that allows for easy adjustment of the position of tiles installed on the platform. [Means for solving the problem] 【0008】 To achieve the aforementioned objective, the first invention provides a platform substructure member comprising: a trough body having a bottom portion and side wall portions erected on both sides of the bottom portion in the width direction; a fixing member fixed to the upper part of the trough body; and a lid member fixed above the fixing member and capable of fixing tiles above it, wherein one of the side wall portions has a notch that connects the internal space and the external space, and the fixing member is provided with an elongated hole in the width direction, and the lid member and the fixing member are positioned and fixed within the range of the elongated hole. 【0009】 The cover member is a lattice-shaped grating cover, and a closing plate that closes the lattice may be fixed to at least the portion corresponding to the elongated hole. 【0010】 The cover member may be fixed by a bolt that passes through the cover member and a cap nut on the inside of the trough body. 【0011】 According to the first invention, by providing an elongated hole in the fixing member attached to the trough body, the fixing position of the lid member, which is fixed to the trough body via the fixing member, can be adjusted. Therefore, with the trough body in place, only the upper lid member can be adjusted. As a result, there is greater flexibility in the distance between the platform and the train, and the work is easier. 【0012】 Furthermore, if the cover is a grating cover, it has high load-bearing capacity from above, eliminating the need for other reinforcing members. In addition, since the bolt holes that are fixed to the fixing member are included, and the positions corresponding to the elongated holes in the fixing member are sealed by the closing plate, it is possible to prevent mortar from flowing down into the trough from the elongated holes when fixing tiles from above with mortar. 【0013】 Furthermore, when fixing the lid member to the fixing member with bolts from above, using cap nuts on the back surface of the fixing member helps to prevent damage to the cables from the bolt tips when laying cables inside. 【0014】 The second invention is a platform substructure using the substructure members according to the first invention, characterized in that a plurality of the platform substructure members are installed along the track-side edge of the platform, tiles are fixed above the cover member, and cables are housed inside the trough body. 【0015】 The fixing member has the elongated hole and a fixing hole for fixing to the trough body, and a closing plate is placed on the lower surface side of the lid member at least at the location of the elongated hole and the fixing hole, and mortar may be applied from above the lid member to join it with the tile. 【0016】 According to the second invention, a platform substructure can be obtained that is easy to construct and allows for easy adjustment of the position of the edge on the track side. 【0017】 Also, by arranging the closing plate at the positions of the long hole and the fixing hole provided in the fixing member, when applying mortar from above the lid member and joining it to the tile, it is possible to prevent the mortar from flowing down from the long hole or the fixing hole into the inside of the trough. 【Advantages of the Invention】 【0018】 According to the present invention, it is possible to provide a home lower structure member or the like that has a simple structure and is easy to adjust the position of the tile installed on the home. 【Brief Description of the Drawings】 【0019】 [Figure 1] Perspective view showing the home lower structure member 1.

Figure 1 is a perspective view showing the platform lower structural member 1, and Figure 2 is an exploded perspective view showing the platform lower structural member 1. The platform lower structural member 1 mainly consists of a trough body 3, a fixing member 5, a cover member 7, etc. 【0021】 The trough body 3 has a bottom portion 9 and side walls 11a and 11b erected on both sides of the bottom portion 9 in the width direction. The trough body 3 is made of resin, for example, and is formed by press molding or injection molding. The space above the bottom portion 9 of the trough body 3, enclosed by both side walls 11a and 11b, serves as a space for housing cables and the like. The opposing direction of the pair of side walls 11a and 11b is the width direction, and the direction perpendicular to this and where the opening is located is the direction in which the cables are laid. 【0022】 Multiple partition fixing parts 17 are provided on the upper surface of the bottom 9 of the trough body 3. The partition fixing parts 17 can hold, for example, plate-shaped partition plates, and can partition the space inside the trough body 3. Note that the partition fixing parts 17 are not necessarily required, and the arrangement and number of partition fixing parts 17 are not limited to the example shown. 【0023】 One side wall portion 11b is provided with a notch 13 that connects the internal space and the external space. The notch 13 is formed in a form in which at least a part of the side wall portion 11b is cut away, and may be formed to extend to the upper end of the side wall portion 11b, or it may be formed as a hole in the side wall portion 11b. The notch 13 functions as a work area that allows work to be performed inside the trough body 3 from the outside of the trough body 3. The other side wall portion 11a does not have a notch 13 formed thereon, and the entire side wall portion 11a is closed. 【0024】 At both ends of the trough body 3 in the cable laying direction, a male fitting portion 15a and a female fitting portion 15b are formed. The male fitting portion 15a and the female fitting portion 15b are shaped to be able to fit together with each other, and by using multiple trough bodies 3 and fitting their male fitting portions 15a and female fitting portions 15b together to connect them, a trough track of a predetermined length can be formed. Details of the male fitting portion 15a and the female fitting portion 15b will be described later. 【0025】 As shown in Figure 2, a fixing member 5 is fixed to the opening at the top of the trough body 3. The material of the fixing member 5 is not particularly limited, but can be metal or resin, etc. The fixing member 5 is a member for fixing the lid member 7, which will be described later, to the trough body 3. Fixing holes 23 are provided near the four corners of the fixing member 5. The fixing holes 23 are holes for fixing to fixing parts 19 provided on the side walls 11a and 11b of the trough body 3, for example, with bolts. 【0026】 Furthermore, the fixing member 5 is provided with positioning holes 25. The positioning holes 25 are located in areas corresponding to projections 21 provided on the upper ends of the side walls 11a and 11b of the trough body 3. By fitting the positioning holes 25 onto the projections 21, the fixing member 5 can be positioned on the trough body 3. The widthwise ends of the fixing member 5 are bent downwards and formed to fit onto the outside of the side walls 11a and 11b of the trough body 3. 【0027】 Furthermore, a pair of elongated holes 27 are provided approximately in the same line at the approximate center of the fixing member 5. The elongated holes 27 are formed to a predetermined length in the width direction of the fixing member 5 (corresponding to the width direction of the trough body 3). The elongated holes 27 are the parts to which the cover member 7 is fixed by bolts. 【0028】 A cover member 7 is fixed above the fixing member 5. The cover member 7 is capable of fixing tiles above it and is the part that receives loads from above and transmits the load to the trough body 3. Since the cover member 7 is required to have load-bearing capacity, in this embodiment it is made of a metal grating cover. By bridging the side wall portions 11a and 11b with the grating cover, the load-bearing capacity can be improved compared to a resin cover member. Furthermore, if the fixing member 5 is made of metal, the load-bearing capacity can be further improved. 【0029】 Figure 3 is a bottom view of the lid member 7. The lid member 7 has a closing plate 29 fixed to a predetermined position on the underside of the lattice-shaped grating lid. That is, the closing plate 29 closes off a portion of the lattice portion of the lid member 7. The closing plate 29 is provided in the approximate center of the lid member 7 so as to connect the two opposing sides (the two sides corresponding to the width direction of the trough body 3) and is formed in a predetermined area so as to surround the entire outer periphery. The closing plate 29 may be provided over the entire bottom surface of the lid member 7, but for weight reduction or other reasons, the lattice may be exposed on the underside in unnecessary areas. 【0030】 A pair of bolt holes 31 are provided in the closing plate 29 located in the center of the lid member 7. The bolt holes 31 are used when fixing the lid member 7 to the fixing member 5. The bolts are inserted by aligning the bolt holes 31 in the lid member 7 with the elongated holes 27 in the fixing member 5, and the nuts are tightened on the lower side of the fixing member 5 to fix the fixing member 5 and the lid member 7 together. 【0031】 Figures 4(a) to 4(c) show the state in which the cover member 7 is fixed to the fixing member 5 with bolts 33 on the trough body 3, respectively, with different fixing positions of the cover member 7. Figure 4(a) shows the state in which the cover member 7 is fixed to the trough body 3 installed on the edge of the platform side 37, with the cover member 7 extending significantly toward the track side 35 (right side in the figure). Figure 4(c) shows the state in which the cover member 7 is fixed to the trough body 3 installed on the edge of the platform side 37, with the end of the cover member 7 at approximately the same position as the end of the platform side 37 (approximately 0 overhang toward the track side 35). Figure 4(b) shows the state in which the cover member 7 is fixed at a position between Figure 4(a) and Figure 4(c). 【0032】 As mentioned above, the lid member 7 is fixed to the fixing member 5 with bolts 33. In this case, the fixing member 5 is provided with an elongated hole 27, so the lid member 7 and the fixing member 5 can be positioned and fixed within the range of the elongated hole 27. In other words, the fixing position of the lid member 7 with respect to the fixing member 5 (trough body 3) can be adjusted. 【0033】 Furthermore, when fixing the lid member 7 to the fixing member 5, the notch 13 formed in the side wall portion 11b of the trough body 3 is used. Since the trough body 3 is positioned so that the notch 13 faces the track side 35, fixing and positioning the lid member 7 is easy. 【0034】 Figures 5(a) and 5(b) are conceptual diagrams viewed from the bottom side of the fixing member 5, showing the positional relationship between the fixing member 5 and the lid member 7 in Figures 4(a) and 4(c), respectively. As mentioned above, in the approximate center of the lid member 7, a closing plate 29 is fixed to the bolt hole 31 in a continuous direction connecting the pair of bolt holes 31. Therefore, regardless of the fixing position of the lid member 7, a closing plate 29 that closes the grid is located at least in the area corresponding to the elongated hole 27. 【0035】 Furthermore, on the outer circumference of the lower side of the lid member 7, the closing plate 29 is positioned at least in the areas corresponding to the fixing holes 23 and positioning holes 25 of the fixing member 5. Therefore, as shown in Figure 5(a), even when the lid member 7 is fixed as close to the track side (left direction in the figure), and as shown in Figure 5(b), even when the lid member 7 is fixed as close to the platform side (right direction in the figure), the elongated holes 27, fixing holes 23, and positioning holes 25 of the fixing member 5 all overlap with the closing plate 29. 【0036】 In this way, the elongated holes 27, fixing holes 23, and positioning holes 25 of the fixing member 5, which are positioned below the lattice portion of the lid member 7, are not exposed upwards. Therefore, the lower part of the lattice portion of the lid member 7 is reliably sealed by the fixing member 5 and the closing plate 29. As a result, even when mortar is applied to the lattice portion from above the lid member 7, the mortar will not flow out downwards (into the trough body 3) through the holes in the fixing member 5, etc. 【0037】 Next, the method of connecting the platform substructure members 1 (trough body 3) will be described. Figures 6(a) and 6(b) show the method of connecting the platform substructure members 1, Figure 7(a) is a plan view of the connected state of the trough body 3, and Figure 7(b) is an enlarged view of part A in Figure 7(a). As shown in Figure 7(b), in a plan view, the male fitting portion 15a has projections that protrude on both sides in the width direction at one end of the trough body 3. On the other hand, the female fitting portion 15b is formed in a roughly U-shape that opens toward the center at the other end of the trough body 3. 【0038】 In this case, the width of the widest part of the female fitting portion 15b (approximately the center of the U-shape) is greater than the width of the male fitting portion 15a, and the opening width at the end of the female fitting portion 15b (the opening width at the end of the trough body 3) is smaller than the width of the male fitting portion 15a. Therefore, when the male fitting portion 15a is fitted into the female fitting portion 15b, the male fitting portion 15a will not come out of the female fitting portion 15b in the connection direction, and the connection can be reliably maintained. 【0039】 When connecting platform substructure members 1 (trough body 3) together, as shown in Figure 6(a), the male fitting portion 15a of one platform substructure member 1 (trough body 3) is fitted into the female fitting portion 15b of the existing platform substructure member 1 (trough body 3) from above. By repeating this process, platform substructure members 1 can be connected to a predetermined length. 【0040】 The fixing member 5 and the cover member 7 are positioned to cover the upper part of the male fitting portion 15a. On the other hand, they are not positioned above the female fitting portion 15b. Therefore, the area above the female fitting portion 15b is open, and the cover member 7, etc., do not get in the way during connection work. Also, when the platform lower structural members 1 are connected, the area above the female fitting portion 15b of one platform lower structural member 1 is closed by the cover member 7 above the male fitting portion 15a of the other platform lower structural member 1. Therefore, when the platform lower structural members 1 are connected, the entire area including the female fitting portion 15b is closed by the cover member 7, etc. 【0041】 As shown in Figure 7(b), a clearance is provided between the male fitting portion 15a and the female fitting portion 15b. For example, the length of the male fitting portion 15a (the thickness of the projection in the connecting direction) is shorter than the length of the widest part of the female fitting portion 15b. Therefore, at the connection point between the platform substructure members 1, it is possible to adjust the position of the platform substructure members 1 with respect to the connecting direction, and to adjust the connection angle between the platform substructure members 1. For example, it is possible to connect the platform substructure members 1 in a curved manner rather than in a straight line. 【0042】 Next, the method for laying the platform substructure members 1 will be explained. Figure 8(a) shows a state in which multiple platform substructure members 1 are connected and arranged at the edge of the platform side 37, and Figure 8(b) is a cross-sectional view of Figure 8(a) along line BB. In the following figures, the cover members 7 are shown in a configuration in which they do not protrude onto the track side 35, but as mentioned above, the arrangement of the cover members 7 is arbitrary. 【0043】 As shown in Figure 8(b), a retaining wall 39 is provided at the lower part of the platform's edge, and multiple platform substructure members 1 are installed above the retaining wall 39 along the edge of the platform on the track side 35. Each platform substructure member 1 is fixed to the retaining wall 39, for example, with anchor bolts. Alternatively, they may be fixed directly to the ground instead of the retaining wall 39. 【0044】 Here, as shown in Figure 8(b), bolts 33 are used to fasten the cover member 7 and the fixing member 5, passing through the bolt holes 31 in the cover member 7 (see Figure 3) and the elongated holes 27 in the fixing member 5 (see Figure 2). In addition, cap nuts 41 are used on the inside side of the trough body 3 (the back side of the fixing member 5). This prevents the tips of the bolts 33 from coming into contact with cables or the like. 【0045】 Figure 9(a) is a plan view showing the platform substructure 50 using the platform substructure member 1, and Figure 9(b) is a cross-sectional view taken along line CC of Figure 9(a). Once the installation of the platform substructure member 1 is complete, mortar is then applied from above the cover member 7, and the tiles 51 are joined to the cover member 7 by the mortar. In this way, the tiles 51 are fixed above the cover member 7 along the edge of the track side 35 of the platform. 【0046】 Furthermore, cables 55 are housed inside the trough body 3. If necessary, partition plates 57 are fixed to the partition fixing section 17. Multiple cables 55 are housed in separate partitioned spaces inside the trough body 3. Cable housing can be performed from the track side 35. 【0047】 As described above, according to this embodiment, since the tiles 51 can be installed directly on top of the platform substructure member 1, precast concrete slabs and H-shaped steel beams that support the precast concrete slabs are not required in the passageway. Therefore, the structure is simple and installation work is easy. In addition, the position of the load-bearing cover member 7 can be easily adjusted in the platform substructure member 1 installed on the track side edge of the platform. Therefore, the position of the cover member 7 can be finely adjusted according to the site conditions, and the distance between the track and the end of the platform can be adjusted, making the work easy. 【0048】 Furthermore, by using a grating cover as the cover member 7, sufficient load-bearing capacity can be ensured, and by fixing the closing plate 29 to the back side of the cover member 7, it is possible to prevent mortar from flowing downwards to the fixing member 5. 【0049】 Furthermore, the connection portion of the lower structural member 1 of the platform allows for some adjustment of its position and angle through clearance. Therefore, it can be easily applied to, for example, curved platform shapes. 【0050】 Furthermore, by using a cap nut 41 on the inside of the trough body 3, it is possible to prevent the cable 55 from being damaged by the tip of the bolt 33 when laying the cable 55. 【0051】 Although embodiments of the present invention have been described above with reference to the attached drawings, the technical scope of the present invention is not limited to the embodiments described above. It is clear to those skilled in the art that various modifications or alterations can be conceived within the scope of the technical idea described in the claims, and these will naturally also fall within the technical scope of the present invention.
