Description

[Technical field]

[0001] This invention relates to an integrated floor slab for platform renovation and a platform structure using the same, and in particular to an integrated floor slab for platform renovation that simplifies platform improvement work and enables it to be completed in one day, and a platform structure using the same. [Background technology]

[0002] At a railway platform, construction work to improve an embankment platform is currently underway. Conventionally, as shown in Fig. 1(A), in step S1000 on the first day, a lining plate made of, for example, steel covering the platform is removed, then in step S1100, an old deck (also called a slab) made of, for example, reinforced concrete (RC) is removed, then in step S1200, construction work under the platform is carried out, such as partial removal of an existing retaining wall, installation of temporary support girders, installation of cable racks, and installation of support girders, then in step S1300, a new deck is installed, and then in step S1400, a temporary lining plate is installed, completing construction work on the first day.

[0003] Then, on the second day, the temporary covering plates installed in step S1400 on the first day are removed in step S2000, and in step S2100 tiles such as platform edge warning tiles and boarding entrance warning tiles are installed on the deck, completing the work.

[0004] Although it does not relate to platform improvement work, the construction of platform doors is described in Patent Document 1. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2022-102004 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the past, the tiles were installed after the deck slab, so construction could not be completed in one day. As shown in FIG. 1(A), after a new deck slab is installed in step S1300, a temporary covering plate must be set up in step S1400, and then on the second day in step S2000, the covering plate must be removed and the tiles must be installed on the deck slab in step S2100. This posed the problem of the many times the temporary covering plate had to be set up and the long construction period.

[0007] The present invention has been made to solve the above-mentioned conventional problems, and its objective is to simplify platform improvement work and complete it in one day. [Means for solving the problem]

[0008] The present invention solves the above problems by providing an integrated floor slab for platform renovation, which is characterized by being provided with height adjustment means and platform edge warning tiles.

[0009] Here, a recess for arranging the platform door housing can further be formed and used as the housing arrangement section.

[0010] Furthermore, a boarding entrance warning tile can be provided for the boarding area.

[0011] The present invention also solves the above-mentioned problem by providing a platform structure in which the integrated floor slab for platform renovation is arranged in the housing arrangement section and the integrated floor slab for platform renovation is arranged in the boarding section. Effect of the Invention

[0012] This invention simplifies platform improvement work and makes it possible to complete it in one day. [Brief description of the drawings]

[Figure 9] Cross-sectional views showing the housing part (A) before construction and (B) after construction DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the contents described in the following embodiments. In addition, the components in the embodiments described below include those that a person skilled in the art can easily imagine, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the components disclosed in the embodiments described below may be appropriately combined or appropriately selected for use.

[0015] The shape of an embodiment of the integrated deck for the housing section of the present invention, which is to be installed in the platform door housing installation section, is shown in Figure 2(A) as a plan view, (B) as a longitudinal section taken along line BB in Figure 2(A), (C) as a longitudinal section taken along line CC in the same, (D) as a cross section taken along line DD, and (E) as a cross section taken along line EE.

[0016] As can be seen clearly in Figure 2, this integrated deck slab 100 for the housing section is integrated with a height adjustment insert 310 for adjusting the height, a platform edge warning tile 320, and a walking block 330, and the walking block 330 is provided with a recess 332 for arranging the platform door housing.

[0017] In FIG. 2, 342 denotes reinforcing bars embedded in the concrete slab 340, 350 denotes lifting inserts, and 360 denotes through holes for rear shear keys 362.

[0018] The integrated floor slab 100 for the housing section is attached to the platform 20 as shown in Figure 3(A) (front view), (B) (plan view of Figure 3(A) seen from B), (C) (sectional view of the same seen from C), Figure 4 (enlarged view of portion IV in Figure 3(A)), Figure 5 (enlarged view of portion V in Figure 3(C)), and Figure 6 (enlarged view of portion VI in Figure 3(B)).

[0019] In Figure 3, reference numeral 10 denotes a foundation, 12 denotes an existing block retaining wall, 14 denotes an existing support column, 16 denotes an existing vertical beam, 22 denotes a platform wall, 24 denotes a platform door, and 200 denotes an integrated deck for the boarding area. A newly installed support beam 18 is provided on top of the existing vertical beam 16 for supporting the integrated decks 100 and 200 of the present invention.

[0020] As shown in detail in Figure 7, the height adjustment insert 310 is equipped with a sheath tube 312 embedded in a hole in the concrete plate 340 of the integrated deck 100, a high nut 314, and a height adjustment bolt 316 screwed into the high nut 314, and by changing the tightening depth of the height adjustment bolt 316, it is possible to adjust the height of the integrated deck 100 relative to the newly installed support girder 18.

[0021] In Figures 4 to 6, 380 is a malt mer for sealing.

[0022] On the other hand, the integrated deck 200 for the boarding section, which is arranged in the boarding section where the platform doors 24 are provided, is equipped with a height adjustment insert 310 similar to the integrated deck 100 for the housing section, a platform edge warning tile 320, a walking block 330, and a lifting insert 350, as shown in Figure 8(A) plan view, (B) longitudinal section along line BB in Figure 8(A), and Figure 8(C) transverse section along CC.

[0023] This integrated boarding floor slab 200 is further provided with a boarding entrance warning tile 370.

[0024] As shown in FIG. 1(B), the construction procedure when using an embodiment of the present invention is as follows: first, in step S3000, the covering plate, for example made of steel, as in the conventional method is removed; then, in step S3100, the old deck slab, for example made of reinforced concrete (RC), as in the conventional method is removed; and then, in step S3200, the new integrated deck slab 100 or 200 according to the present invention is installed.

[0025] Cross sections of the housing before and after construction are shown in Figures 9(A) and 9(B). Before construction, as shown in Figure 9(A), a block retaining wall 12, for example, is built on a foundation 10 that is parallel to a roadbed 8 on which the rails are laid, and a floor slab 90 made of, for example, reinforced concrete (RC) is placed on top of that. A platform edge warning tile 320 is placed on the floor slab 90.

[0026] In contrast, after construction, as shown in Figure 9(B), a cable rack 17 and new support girders 18 are installed on top of the existing vertical girders 16 on the block retaining wall 12, and the integrated floor slab for the housing 100 with integrated platform edge warning tile 320 is placed on top of that. Since the height H from the rail surface is specified to be equal to or less than a specified value (for example, 1100 mm), the height of the platform edge warning tile 320 is adjusted by raising or lowering the integrated floor slab for the housing 100 with height adjustment bolts 316. In Figure 9(B), 362 is a shear key.

[0027] According to this invention, a height adjustment means is provided on the integrated deck, eliminating the need for height adjustment work under the platform. Furthermore, since tiles are already installed on the integrated deck, the work can be completed in one day.

[0028] Furthermore, the application of this invention is not limited to embankment-type platforms, but can also be applied to improvements to platforms that already have floor panels installed. [Explanation of symbols]
