Description

本発明は、固定部材及びホームドア装置並びにホームドア装置の設置方法に関する。 The present invention relates to a fixing member, a platform door device, and a method of installing the platform door device.

ホームドア装置は、鉄道駅のプラットホームに設置される一種の自動ドア装置である。ホームドア装置は、乗客が列車に乗降する際に開扉されて、乗客の列車への乗降を可能にし、それ以外の場合は、閉扉されて、プラットホーム上に所在する乗客の軌道への転落を防止する。 Platform door devices are a type of automatic door device installed on the platform of railway stations. Platform door devices are opened when passengers get on and off the train to allow passengers to get on and off the train, otherwise they are closed to allow passengers located on the platform to fall into orbit. To prevent.

ホームドア装置を、鉄道駅のプラットホームに据え付け固定する際には、プラットホームとホームドア装置の間にあって、ホームドア装置をプラットホームに固定する構造が必要とされる。以下、本明細書において、かかる構造を、ホームドア装置の基礎構造と呼ぶことにする。 When the platform door device is installed and fixed to the platform of a railway station, a structure is required between the platform and the platform door device to fix the platform door device to the platform. Hereinafter, in the present specification, such a structure will be referred to as a basic structure of a platform door device.

一般に、ホームドア装置の新設工事は、鉄道の運行がされていない深夜に行われるので、作業可能な時間が制限される。１ホーム分のホームドア装置の設置に１晩で完了するが、基礎構造の設置工事には数日を要する。基礎構造の設置工事が施工される数日間の鉄道の運行がされる時間においては、仕掛かり中の基礎構造が乗客の通行の妨げにならないようにする必要がある。かかる事情を考慮したホームドア装置の基礎構造に係る発明が既に出願されている。 In general, new construction of platform door devices is carried out at midnight when the railway is not in operation, so that the workable time is limited. Installation of the platform door device for one home is completed in one night, but it takes several days to install the foundation structure. It is necessary to prevent the foundation structure in progress from obstructing the passage of passengers during the several days when the railway is in operation for the installation work of the foundation structure. An invention relating to the basic structure of a platform door device in consideration of such circumstances has already been applied for.

例えば、特許文献１には、プラットホームにホームドア装置の基礎構造を設置するために、プラットホームの上面に円形断面形状の嵌合溝を穿設し、更に嵌合溝の溝底からプラットホームの下面に貫通する貫通孔を穿設することが記載されている。特許文献１に記載の発明によれば、基礎構造が貫通孔と嵌合溝の中に収容されるので、仕掛かり中の基礎構造が乗客の通行の妨げになることがない。 For example, in Patent Document 1, in order to install the basic structure of the platform door device on the platform, a fitting groove having a circular cross-sectional shape is formed on the upper surface of the platform, and further, from the groove bottom of the fitting groove to the lower surface of the platform. It is described to make a through hole to penetrate. According to the invention described in Patent Document 1, since the basic structure is housed in the through hole and the fitting groove, the basic structure in the process of being in the process does not obstruct the passage of passengers.

特許第４２７２７７３号公報Japanese Patent No. 4272773

特許文献１に記載の発明においては、プラットホームの床面に嵌合溝を形成するために、プラットホームの床面に斫工事を施す必要がある。しかしながら、斫工事は熟練と重労働が要求される煩雑な作業である。斫工事によって高精度の加工を行おうとすれば、更に手間を要する。また、斫工事用の工具の動力として使用する圧縮空気を確保する必要があるので、準備作業も煩雑である。そのために、特許文献１に記載の発明においては、労力とコストが嵩むという問題がある。 In the invention described in Patent Document 1, it is necessary to perform shaving work on the floor surface of the platform in order to form a fitting groove on the floor surface of the platform. However, chipping work is a complicated work that requires skill and hard labor. If high-precision machining is to be performed by chipping work, it will take more time and effort. In addition, since it is necessary to secure compressed air to be used as a power source for the tool for chipping work, the preparatory work is complicated. Therefore, in the invention described in Patent Document 1, there is a problem that labor and cost increase.

本発明は、上記の問題に鑑みてなされたものであり、ホームドア装置の基礎構造を短期間に容易に構成できる固定部材を提供することを目的とする。また、該固定部材を備えるホームドア装置を提供することを目的とする。並びにホームドア装置の設置方法を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a fixing member capable of easily constructing a basic structure of a platform door device in a short period of time. Another object of the present invention is to provide a platform door device including the fixing member. It also aims to provide a method of installing platform door devices.

上記の目的を達成するために、本発明に係る固定部材は、ホームドア装置をプラットホームに固定する固定部材であって、プラットホームに穿設された埋込穴に埋め込まれて固定される埋込パイプと、埋込パイプに挿通される支持部材と、支持部材に設けられて、ホームドア装置を支承する支承部材と、支持部材を埋込パイプに固定する固定手段と、を備える。 In order to achieve the above object, the fixing member according to the present invention is a fixing member for fixing the platform door device to the platform, and is an embedded pipe embedded and fixed in an embedding hole formed in the platform. A support member inserted into the embedded pipe, a support member provided on the support member to support the platform door device, and a fixing means for fixing the support member to the embedded pipe are provided.

本発明によれば、埋込パイプが埋込穴に埋め込まれるので、埋込パイプの上端が、プラットホームの床面の上方に突出することがない。そのため、埋込パイプの取り付け後、次工程の施工まで時間が空いても、埋込パイプがプラットホーム上を移動する乗降客の妨げになることがない。また、支持部材と支承部材の取り付けを、ホームドア装置の設置工事と同時に行うことができるので、埋込パイプの取り付け後、ホームドア装置の設置工事までに時間が空いても、支持部材と支承部材がプラットホーム上を移動する乗降客の妨げになることがない。また、埋込穴を設置する際には斫工事を必要としない。埋込穴は、コアドリル等を使うことによって、容易に、短時間で、穿設できる。そのため、本発明によれば、ホームドア装置の基礎構造を短期間に容易に設置できる。その結果、ホームドア装置の設置に掛かる労力とコストを削減することができる。 According to the present invention, since the embedded pipe is embedded in the embedded hole, the upper end of the embedded pipe does not protrude above the floor surface of the platform. Therefore, even if there is a time between the installation of the embedded pipe and the construction of the next process, the embedded pipe does not hinder passengers moving on the platform. In addition, since the support member and the bearing member can be attached at the same time as the installation work of the platform door device, the support member and the bearing member can be attached even if there is a time between the installation work of the platform door device after the installation of the embedded pipe. The members do not interfere with passengers moving on the platform. In addition, no shaving work is required when installing the embedding hole. The embedding hole can be easily drilled in a short time by using a core drill or the like. Therefore, according to the present invention, the basic structure of the platform door device can be easily installed in a short period of time. As a result, the labor and cost required for installing the platform door device can be reduced.

以下、本発明の実施形態に係る固定部材の構成と作用を、図面を参照しながら詳細に説明する。なお、各図面においては、同一または同等の部分に同一の符号を付している。 Hereinafter, the configuration and operation of the fixing member according to the embodiment of the present invention will be described in detail with reference to the drawings. In each drawing, the same or equivalent parts are designated by the same reference numerals.

図１は、本発明の実施の形態に係る固定部材５を用いて、ホームドア装置１をプラットホームの床板２に据え付けた状態を示す説明図である。図１に示すように、ホームドア装置１は、床板２に固定された戸袋３と、戸袋３に進退自在に支持される２枚の扉体４とを備えている。図１は、ホームドア装置１が閉扉された状態を示していて、扉体４は戸袋３の外に引き出されている。ホームドア装置１が開扉状態にある時は、扉体４は戸袋３の中に引き込まれる。なお、戸袋３の中には図示しない駆動機構が内蔵されていて、扉体４の進退はこの図示しない駆動機構によって行われる。また、床板２は、プラットホームの床面を構成するコンクリート板である。 FIG. 1 is an explanatory view showing a state in which the platform door device 1 is installed on the floor plate 2 of the platform by using the fixing member 5 according to the embodiment of the present invention. As shown in FIG. 1, the platform door device 1 includes a door pocket 3 fixed to a floor plate 2 and two door bodies 4 supported by the door pocket 3 so as to be able to move forward and backward. FIG. 1 shows a state in which the platform door device 1 is closed, and the door body 4 is pulled out of the door pocket 3. When the platform door device 1 is in the open state, the door body 4 is pulled into the door pocket 3. A drive mechanism (not shown) is built in the door pocket 3, and the door body 4 is moved forward and backward by the drive mechanism (not shown). Further, the floor board 2 is a concrete board constituting the floor surface of the platform.

固定部材５は、戸袋３を床板２に固定する部材である。図１に示す例においては、２台の固定部材５が左右に間隔を空けて配置されていて、戸袋３は、２台の固定部材５に両持支持されている。 The fixing member 5 is a member that fixes the door pocket 3 to the floor plate 2. In the example shown in FIG. 1, two fixing members 5 are arranged on the left and right at intervals, and the door pocket 3 is supported by both fixing members 5.

図２は、図１に記載の固定部材５とその周辺の構成を拡大して示す説明図である。図２に示すように、固定部材５は、プラットホームの床板２の上面に穿設されて下向に延びる埋込穴６に埋め込まれて固定される埋込パイプ７と、埋込パイプ７に挿通される支持部材８とを備えている。また、支持部材８の上端には戸袋３を支承する支承部材９が固定されていて、支承部材９の上面には戸袋３の据え付け部材３ａが載置される。そして、据え付け部材３ａは、ボルト１０によって、支承部材９に固定される。その結果、ホームドア装置１（図２において図示なし）は、固定部材５によって、床板２に固定される。このように、固定部材５を埋込穴６に埋め込んで固定することによって、ホームドア装置１をプラットホームの床板２に固定する基礎構造が構成される。 FIG. 2 is an enlarged explanatory view showing the configuration of the fixing member 5 shown in FIG. 1 and its surroundings. As shown in FIG. 2, the fixing member 5 is inserted into the embedded pipe 7 and the embedded pipe 7 which are bored in the upper surface of the floor plate 2 of the platform and embedded and fixed in the embedded hole 6 extending downward. The support member 8 is provided. Further, a support member 9 for supporting the door pocket 3 is fixed to the upper end of the support member 8, and an installation member 3a for the door pocket 3 is placed on the upper surface of the support member 9. Then, the installation member 3a is fixed to the support member 9 by the bolt 10. As a result, the platform door device 1 (not shown in FIG. 2) is fixed to the floor plate 2 by the fixing member 5. By embedding the fixing member 5 in the embedding hole 6 and fixing the platform door device 1 in this way, a basic structure for fixing the platform door device 1 to the floor plate 2 of the platform is constructed.

次に、プラットホームの床板２に固定部材５を固定して、固定部材５に戸袋３を固定して、ホームドア装置１を床板２に固定する手順、つまり、プラットホームにホームドア装置１を設置する方法を説明する。 Next, the procedure of fixing the fixing member 5 to the floor plate 2 of the platform, fixing the door pocket 3 to the fixing member 5, and fixing the platform door device 1 to the floor plate 2, that is, installing the platform door device 1 on the platform. The method will be explained.

図３は、床板２に固定部材５を固定して、固定部材５に戸袋３を固定するプロセスを時系列に沿って示す図である。図３（Ａ）は加工前のプラットホームの床板２を示す断面図である。この床板２に、図示しないコアドリルを使って、図３（Ｂ）に示すような埋込穴６を穿設する。なお、図３（Ａ）に示す状態から図３（Ｂ）に示す状態に至る工程は、本発明の埋込穴穿設工程の具体例である。 FIG. 3 is a diagram showing a process of fixing the fixing member 5 to the floor plate 2 and fixing the door pocket 3 to the fixing member 5 in chronological order. FIG. 3A is a cross-sectional view showing the floor plate 2 of the platform before processing. An embedded hole 6 as shown in FIG. 3B is formed in the floor plate 2 using a core drill (not shown). The step from the state shown in FIG. 3A to the state shown in FIG. 3B is a specific example of the embedding hole drilling step of the present invention.

埋込穴６が穿孔されたら、図３（Ｃ）に示すように、埋込穴６に埋込パイプ７を埋め込む。その後、埋込穴６と埋込パイプ７の間の図示しない隙間に樹脂材料を充填して、固化させて、埋込パイプ７を埋込穴６に固定する。なお、埋込パイプ７は、図３（Ｃ）に示すように、上端を床板２の上面と同じ高さにするが、埋込パイプ７の上端が床板２の上面より低くなるようにしても良い。このように、埋込パイプ７は、その上端が床板２の上面から突出しないように、埋込穴６に取り付けられる。なお、埋込パイプ７の固定をより確実にするため、埋込パイプ７の外周の表面にプレス加工を加えて凹凸を形成しても良い。物理的あるいは化学的手段で粗面を形成しても良い。 After the embedding hole 6 is drilled, the embedding pipe 7 is embedded in the embedding hole 6 as shown in FIG. 3C. After that, a resin material is filled in a gap (not shown) between the embedding hole 6 and the embedding pipe 7 and solidified to fix the embedding pipe 7 in the embedding hole 6. As shown in FIG. 3C, the upper end of the embedded pipe 7 is set to the same height as the upper surface of the floor plate 2, but the upper end of the embedded pipe 7 may be lower than the upper surface of the floor plate 2. good. In this way, the embedded pipe 7 is attached to the embedded hole 6 so that the upper end thereof does not protrude from the upper surface of the floor plate 2. In order to secure the embedded pipe 7 more reliably, the surface of the outer periphery of the embedded pipe 7 may be pressed to form irregularities. Rough surfaces may be formed by physical or chemical means.

このように、埋込穴６と埋込パイプ７の間の隙間に充填した樹脂材料を固化させて埋込パイプ７を固定する。この状態からホームドア装置１の設置工事まで、数日または数週の間、時間が空くことがある。しかしながら、埋込パイプ７の上端が床板２の上面から突出しないので、乗降客の通行の妨げにはならない。 In this way, the resin material filled in the gap between the embedding hole 6 and the embedding pipe 7 is solidified to fix the embedding pipe 7. It may take several days or weeks from this state to the installation work of the platform door device 1. However, since the upper end of the embedded pipe 7 does not protrude from the upper surface of the floor plate 2, it does not hinder the passage of passengers.

埋込パイプ７が埋込穴６に固定されたら、図３（Ｄ）に示すように、支持部材８を埋込パイプ７の内部に挿入する。その後、埋込パイプ７と支持部材８の間の図示しない隙間に樹脂材料を充填して、固化させて、支持部材８を埋込パイプ７に固定する。なお、前述したように、支持部材８の上端には支承部材９が固定されている。このように、本実施の形態においては、埋込パイプ７と支持部材８の間の図示しない隙間に充填される樹脂材料が、支持部材８を埋込パイプ７に固定する固定手段として機能する。なお、図３（Ｃ）と図３（Ｄ）に示す工程は、本発明の固定部材取り付け工程の具体例である。また、上記においては、支持部材８の上端に支承部材９を固定する例を示したが、支持部材８と支承部材９は、このようなものには限定されない。例えば、支持部材８と支承部材９とを一体成型するようにしても良い。つまり、支持部材８の上端に支承部材９が設けられていれば良い。 After the embedded pipe 7 is fixed in the embedded hole 6, the support member 8 is inserted into the embedded pipe 7 as shown in FIG. 3 (D). After that, a resin material is filled in a gap (not shown) between the embedded pipe 7 and the support member 8 and solidified, and the support member 8 is fixed to the embedded pipe 7. As described above, the support member 9 is fixed to the upper end of the support member 8. As described above, in the present embodiment, the resin material filled in the gap (not shown) between the embedded pipe 7 and the support member 8 functions as a fixing means for fixing the support member 8 to the embedded pipe 7. The steps shown in FIGS. 3C and 3D are specific examples of the fixing member attaching step of the present invention. Further, in the above, an example in which the support member 9 is fixed to the upper end of the support member 8 is shown, but the support member 8 and the support member 9 are not limited to such a member. For example, the support member 8 and the support member 9 may be integrally molded. That is, the support member 9 may be provided at the upper end of the support member 8.

支持部材８が埋込パイプ７に固定されたら、図３（Ｅ）に示すように、支承部材９の上面に戸袋３（図示なし）の据え付け部材３ａを載置して、ボルト１０で固定する。その結果、戸袋３は固定部材５を介して床板２に固定される。なお、図３（Ｅ）に示す工程は、本発明のホームドア装置取り付け工程の具体例である。 After the support member 8 is fixed to the embedded pipe 7, as shown in FIG. 3 (E), the installation member 3a of the door pocket 3 (not shown) is placed on the upper surface of the support member 9 and fixed with bolts 10. .. As a result, the door pocket 3 is fixed to the floor plate 2 via the fixing member 5. The process shown in FIG. 3E is a specific example of the platform door device mounting process of the present invention.

なお、上記において、埋込パイプ７と支持部材８の間の隙間に充填された樹脂材料が固化した後に、支承部材９に据え付け部材３ａを取り付ける例を示したが、樹脂材料が固化する前に支承部材９に据え付け部材３ａを取り付けるようにしても良い。あるいは、埋込パイプ７と支持部材８の間の隙間を小さくして、樹脂材料の充填を省いても良い。 In the above, an example of attaching the mounting member 3a to the bearing member 9 after the resin material filled in the gap between the embedded pipe 7 and the support member 8 has solidified has been shown, but before the resin material solidifies. The installation member 3a may be attached to the support member 9. Alternatively, the gap between the embedded pipe 7 and the support member 8 may be reduced to omit filling the resin material.

このように、本実施の形態によれば、コアドリルを使って床板２に埋込穴６を穿設して、埋込穴６に固定部材５を埋め込んで固定することによって、固定部材５を設置できる。また、埋込パイプ７の上端が床板２の上方に突出しない。そのため、埋込パイプ７を埋込穴６に埋め込んで樹脂材料の固化を待つ間に、乗降客が埋込パイプ７に接触することがない。
なお、埋込穴６を高い精度で穿設することは困難であり、時間やコストがかかる。しかしながら、埋込パイプ７を高い精度で製造し、床板２に対して埋込パイプ７を垂直に挿入することは容易に行える。
また、本実施の形態によれば、床板２に斫工事を施す必要がない。
そのため、本実施の形態によれば、固定部材５を、高精度、低コストかつ短時間で設置することができる。 As described above, according to the present embodiment, the fixing member 5 is installed by drilling the embedding hole 6 in the floor plate 2 using the core drill and embedding and fixing the fixing member 5 in the embedding hole 6. it can. Further, the upper end of the embedded pipe 7 does not protrude above the floor plate 2. Therefore, passengers do not come into contact with the embedded pipe 7 while the embedded pipe 7 is embedded in the embedded hole 6 and waits for the resin material to solidify.
It is difficult to drill the embedded hole 6 with high accuracy, which takes time and cost. However, it is easy to manufacture the embedded pipe 7 with high accuracy and insert the embedded pipe 7 perpendicularly to the floor plate 2.
Further, according to the present embodiment, it is not necessary to perform chipping work on the floor plate 2.
Therefore, according to the present embodiment, the fixing member 5 can be installed with high accuracy, low cost, and in a short time.

（第１の変形例）
支持部材８は、樹脂材料によって埋込パイプ７に固定されるものには限定されない。第１の変形例においては、支持部材８及び埋込パイプ７と同軸に配置されて、支持部材８を埋込パイプ７に引き込む方向に推力を作用させるボルト１１によって、支持部材８が埋込パイプ７に固定される例を示す。 (First modification)
The support member 8 is not limited to the one fixed to the embedded pipe 7 by the resin material. In the first modification, the support member 8 is arranged coaxially with the support member 8 and the embedded pipe 7, and the support member 8 is provided with the embedded pipe by a bolt 11 that exerts a thrust in the direction of pulling the support member 8 into the embedded pipe 7. An example of being fixed to 7 is shown.

図４は、第１の変形例に係る固定部材５の構成を示す図であって、図４（Ａ）は支持部材８の構成を示す正面図であり、図４（Ｂ）は固定部材５を床板２に設置した状態を示す説明図である。 4A and 4B are views showing the configuration of the fixing member 5 according to the first modification, FIG. 4A is a front view showing the configuration of the support member 8, and FIG. 4B is a fixing member 5. It is explanatory drawing which shows the state which was installed on the floor board 2.

図４（Ａ）に示すように、支持部材８の下面には、ボルト１１が支持部材８と同軸に配置されていて、支持部材８の下端に固定されている。また、ボルト１１にはナット１２が螺合される。 As shown in FIG. 4A, bolts 11 are arranged coaxially with the support member 8 on the lower surface of the support member 8 and are fixed to the lower end of the support member 8. Further, a nut 12 is screwed into the bolt 11.

図４（Ｂ）に示すように、第１の変形例においても、埋込パイプ７はプラットホームの床板２に穿設された埋込穴６に埋め込まれて、そこに固定される。支持部材８は上方から埋込パイプ７に差し込まれる。支持部材８の下面に固定されたボルト１１は、埋込パイプ７の下方に突出していて、ボルト１１の先端にはナット１２が螺合されている。ボルト１１は支持部材８及び埋込パイプ７に対して同軸に配置されている。なお、支持部材８の埋込パイプ７への差し込みは、ボルト１１の先端からナット１２を取り外した状態で行う。そして、支持部材８を埋込パイプ７へ差し込んだ後で、ボルト１１の埋込パイプ７の下方に突出する端部にナット１２を螺合させる。 As shown in FIG. 4 (B), also in the first modification, the embedded pipe 7 is embedded in the embedded hole 6 formed in the floor plate 2 of the platform and fixed therein. The support member 8 is inserted into the embedded pipe 7 from above. The bolt 11 fixed to the lower surface of the support member 8 projects below the embedded pipe 7, and a nut 12 is screwed into the tip of the bolt 11. The bolt 11 is arranged coaxially with the support member 8 and the embedded pipe 7. The support member 8 is inserted into the embedded pipe 7 with the nut 12 removed from the tip of the bolt 11. Then, after the support member 8 is inserted into the embedded pipe 7, the nut 12 is screwed into the end of the bolt 11 that protrudes downward from the embedded pipe 7.

図４（Ｂ）に示す状態において、ナット１２がボルト１１に対して上昇する方向にナット１２を回転させると、支持部材８が埋込パイプ７の内部に引き込まれる。このように、ナット１２を回転させると、支持部材８に推力が作用して、支持部材８が埋込パイプ７の内部に引き込まれる。その結果、支承部材９とナット１２の間に埋込パイプ７が挟まれるので、支持部材８は埋込パイプ７に固定される。 In the state shown in FIG. 4B, when the nut 12 is rotated in the direction in which the nut 12 rises with respect to the bolt 11, the support member 8 is pulled into the embedded pipe 7. When the nut 12 is rotated in this way, a thrust acts on the support member 8 and the support member 8 is pulled into the embedded pipe 7. As a result, the embedded pipe 7 is sandwiched between the bearing member 9 and the nut 12, so that the support member 8 is fixed to the embedded pipe 7.

このように、第１の変形例においては、ボルト１１が、支持部材８の下端に固定されていて、ボルト１１の先端は埋込パイプ７の下方に突出している。ナット１２は、埋込パイプ７の下方において、ボルト１１と螺合される。また、図４（Ｂ）に示す状態において、ナット１２は埋込パイプ７の下端面を押圧している。 As described above, in the first modification, the bolt 11 is fixed to the lower end of the support member 8, and the tip of the bolt 11 projects below the embedded pipe 7. The nut 12 is screwed into the bolt 11 below the embedded pipe 7. Further, in the state shown in FIG. 4B, the nut 12 presses the lower end surface of the embedded pipe 7.

第１の変形例に係る固定部材５においては、支持部材８及び埋込パイプ７と同軸に配置されたボルト１１が、支持部材８を埋込パイプ７に固定する固定手段として機能する。そのため、支持部材８と埋込パイプ７との間の隙間に充填される樹脂材料を固定手段とする場合に比べて、短時間で、支持部材８を埋込パイプ７に固定することができる。その結果、基礎構造の設置に要する作業時間が更に短縮される。 In the fixing member 5 according to the first modification, the support member 8 and the bolts 11 arranged coaxially with the embedded pipe 7 function as fixing means for fixing the support member 8 to the embedded pipe 7. Therefore, the support member 8 can be fixed to the embedded pipe 7 in a shorter time than when the resin material filled in the gap between the support member 8 and the embedded pipe 7 is used as the fixing means. As a result, the work time required to install the foundation structure is further shortened.

また、図４（Ａ）に示すように、ボルト１０には、ナット１０ａが２個ずつ、螺合されている。そして、戸袋３（図示なし）の据え付け部材３ａは、ナット１０ａの間に挟まれて、ボルト１０に固定される。ナット１０ａの高さは自由に変更できるので、ナット１０ａの高さを変更することによって、据え付け部材３ａの据え付け高さを調整することができる。また、一方のボルト１０と他方のボルト１０の間で、ナット１０ａの高さを個別に調整することによって、据え付け部材３ａの固定部材５に対する傾きを調整することができる。 Further, as shown in FIG. 4A, two nuts 10a are screwed into the bolt 10. Then, the installation member 3a of the door pocket 3 (not shown) is sandwiched between the nuts 10a and fixed to the bolt 10. Since the height of the nut 10a can be freely changed, the installation height of the installation member 3a can be adjusted by changing the height of the nut 10a. Further, by individually adjusting the height of the nut 10a between one bolt 10 and the other bolt 10, the inclination of the installation member 3a with respect to the fixing member 5 can be adjusted.

このように、第１の変形例に係る固定部材５は、固定部材５を床板２に固定した後で、ナット１０ａの高さを調整することによって、ホームドア装置１の据え付け高さと、支承部材９に対する傾きを調整できる。そのため、固定部材５を床板２に据え付ける際に、固定部材５の据え付け姿勢と据え付け高さについて要求される精度の水準が緩和される。 As described above, the fixing member 5 according to the first modification is the mounting height of the platform door device 1 and the bearing member by adjusting the height of the nut 10a after fixing the fixing member 5 to the floor plate 2. The inclination with respect to 9 can be adjusted. Therefore, when the fixing member 5 is installed on the floor plate 2, the level of accuracy required for the installation posture and the installation height of the fixing member 5 is relaxed.

また、床板２の仕上げ精度と埋込穴６の加工精度には限界があるので、固定部材５の据え付け姿勢と据え付け高さを、高精度で調整することは困難であった。前述したように、第１の変形例に係る固定部材５においては、据え付け姿勢と据え付け高さについて要求される精度の水準が緩和されるので、固定部材５の床板２に固定する際の据え付け調整が容易になる。このため、固定部材５の床板２への取り付け工事が容易になる。 Further, since there is a limit to the finishing accuracy of the floor plate 2 and the machining accuracy of the embedded hole 6, it is difficult to adjust the installation posture and the installation height of the fixing member 5 with high accuracy. As described above, in the fixing member 5 according to the first modification, the level of accuracy required for the installation posture and the installation height is relaxed, so that the installation adjustment when fixing the fixing member 5 to the floor plate 2 is relaxed. Becomes easier. Therefore, the work of attaching the fixing member 5 to the floor plate 2 becomes easy.

また、図４（Ａ）に示すように、支承部材９の下面には、下方に突出するスペーサ９ａが形成されている。そして、図４（B）に示すように、固定部材５が構成された状態において、スペーサ９ａは埋込パイプ７の上端に当接する。そのため、支承部材９の下面と床板２の上面と間に隙間が形成される。このような隙間が形成されるので、仮に床板２に凹凸あるいは傾斜があっても、支承部材９が床板２と干渉することがない。また、支承部材９が傾くことがない。 Further, as shown in FIG. 4A, a spacer 9a projecting downward is formed on the lower surface of the bearing member 9. Then, as shown in FIG. 4B, the spacer 9a comes into contact with the upper end of the embedded pipe 7 in the state where the fixing member 5 is configured. Therefore, a gap is formed between the lower surface of the bearing member 9 and the upper surface of the floor plate 2. Since such a gap is formed, even if the floor plate 2 is uneven or inclined, the bearing member 9 does not interfere with the floor plate 2. Further, the bearing member 9 does not tilt.

（第２の変形例）
支持部材８を埋込パイプ７に固定するボルト１１は、支持部材８に固定されて、ナット１２が螺合されるものには限定されない。第２の変形例においては、支持部材８に形成された雌ねじ１３にボルト１１が螺合される例を示す。 (Second modification)
The bolt 11 that fixes the support member 8 to the embedded pipe 7 is not limited to the one that is fixed to the support member 8 and the nut 12 is screwed into the support member 8. In the second modification, an example in which the bolt 11 is screwed into the female screw 13 formed on the support member 8 is shown.

図５は、第２の変形例に係る固定部材５の構成を示す図であって、図５（Ａ）は支持部材８と支承部材９の構成を示す断面図であり、図５（Ｂ）は固定部材５を床板２に設置した状態を示す断面図である。 5A and 5B are views showing the configuration of the fixing member 5 according to the second modification, FIG. 5A is a cross-sectional view showing the configuration of the support member 8 and the support member 9, and FIG. 5B is a cross-sectional view. Is a cross-sectional view showing a state in which the fixing member 5 is installed on the floor plate 2.

図５（Ａ）に示すように、第２の変形例に係る支持部材８には、支持部材８の下面から上方に向かう雌ねじ１３が形成されていて、雌ねじ１３にはボルト１１が螺合されている。また、ボルト１１にはワッシャ１４が取り付けられている。 As shown in FIG. 5 (A), the support member 8 according to the second modification is formed with a female screw 13 extending upward from the lower surface of the support member 8, and a bolt 11 is screwed into the female screw 13. ing. A washer 14 is attached to the bolt 11.

図５（Ｂ）に示すように、ボルト１１は埋込パイプ７の下方から、埋込パイプ７に差し込まれて、埋込パイプ７の内部で雌ねじ１３と螺合される。また、ワッシャ１４の外径は埋込パイプ７の外径よりも大きくされている。そのため、ボルト１１を締め上げて、支持部材８に推力を作用させて、支持部材８を埋込パイプ７の中に引き込むと、支承部材９とナット１２の間に埋込パイプ７が挟まれるので、支持部材８が埋込パイプ７に固定される。 As shown in FIG. 5B, the bolt 11 is inserted into the embedded pipe 7 from below the embedded pipe 7 and screwed with the female screw 13 inside the embedded pipe 7. Further, the outer diameter of the washer 14 is made larger than the outer diameter of the embedded pipe 7. Therefore, when the bolt 11 is tightened, a thrust is applied to the support member 8 and the support member 8 is pulled into the embedded pipe 7, the embedded pipe 7 is sandwiched between the bearing member 9 and the nut 12. , The support member 8 is fixed to the embedded pipe 7.

このように、第２の変形例においては、ボルト１１は、埋込パイプ７の下方から、前記埋込パイプ７の内部に挿入されている。雌ねじ１３は支持部材８に固定されていて、雌ねじ１３にはボルト１１が螺合される。図５（Ｂ）に示すように、ボルト１１を締め上げると、ボルト１１は埋込パイプ７の下端面を押圧する。 As described above, in the second modification, the bolt 11 is inserted into the embedded pipe 7 from below the embedded pipe 7. The female screw 13 is fixed to the support member 8, and the bolt 11 is screwed into the female screw 13. As shown in FIG. 5B, when the bolt 11 is tightened, the bolt 11 presses the lower end surface of the embedded pipe 7.

（第３の変形例）
支持部材８を埋込パイプ７に固定するボルト１１は、支持部材８に形成された雌ねじ１３に螺合されるものには限定されない。第３の変形例においては、埋込パイプ７に形成された雌ねじ１５にボルト１１が螺合される例を示す。 (Third variant)
The bolt 11 for fixing the support member 8 to the embedded pipe 7 is not limited to the one screwed into the female screw 13 formed on the support member 8. In the third modification, an example in which the bolt 11 is screwed into the female screw 15 formed in the embedded pipe 7 is shown.

図６は、第３の変形例に係る固定部材５の構成を示す図であって、図６（Ａ）は支持部材８と支承部材９の構成を示す断面図であり、図６（Ｂ）は固定部材５を床板２に設置した状態を示す断面図である。 6A and 6B are views showing the configuration of the fixing member 5 according to the third modification, FIG. 6A is a cross-sectional view showing the configuration of the support member 8 and the support member 9, and FIG. 6B is a cross-sectional view. Is a cross-sectional view showing a state in which the fixing member 5 is installed on the floor plate 2.

図６（Ａ）に示すように、埋込パイプ７は下端に底板７ａを備えている。底板７ａには、底板７ａを貫通する雌ねじ１５が形成されている。支持部材８は、中空のパイプで構成されていて、下端に底板８ａを備えている。底板８ａには、底板８ａを貫通する貫通穴８ｂが形成されている。また、支承部材９には貫通穴９ｂが形成されている。そのため、貫通穴９ｂを通って支持部材８の内部に工具を挿入することができる。 As shown in FIG. 6A, the embedded pipe 7 is provided with a bottom plate 7a at the lower end. A female screw 15 penetrating the bottom plate 7a is formed on the bottom plate 7a. The support member 8 is composed of a hollow pipe and has a bottom plate 8a at the lower end. The bottom plate 8a is formed with a through hole 8b that penetrates the bottom plate 8a. Further, a through hole 9b is formed in the bearing member 9. Therefore, the tool can be inserted into the support member 8 through the through hole 9b.

図６（Ａ）に示すように、ボルト１１は支持部材８の中空部に挿入されている。そして、ボルト１１の貫通穴８ｂを通って、支持部材８の下方に突出している。そして、支持部材８の下方に突出したボルト１１の先端は雌ねじ１５に螺合されている。この状態において、支承部材９の貫通穴９ｂから、図示しない工具を差し入れて、ボルト１１を回転させて締め上げると、図６（Ｂ）に示すように、支持部材８は埋込パイプ７に固定される。 As shown in FIG. 6A, the bolt 11 is inserted into the hollow portion of the support member 8. Then, it projects below the support member 8 through the through hole 8b of the bolt 11. The tip of the bolt 11 protruding downward from the support member 8 is screwed into the female screw 15. In this state, when a tool (not shown) is inserted through the through hole 9b of the bearing member 9 and the bolt 11 is rotated and tightened, the support member 8 is fixed to the embedded pipe 7 as shown in FIG. 6 (B). Will be done.

このように、第３の変形例においては、ボルト１１は、支持部材８の上方から、支持部材８に挿通されて、ボルト１１の先端は支持部材８の下方に突出する。雌ねじ１５は埋込パイプ７に固定されていて、雌ねじ１５にはボルト１１が螺合される。 As described above, in the third modification, the bolt 11 is inserted into the support member 8 from above the support member 8, and the tip of the bolt 11 projects below the support member 8. The female screw 15 is fixed to the embedded pipe 7, and a bolt 11 is screwed into the female screw 15.

なお、安全上の問題があるので、軌道上での作業は厳しく制限されている。また、作業環境も良くない。第３の変形例に係る固定部材５は、取り付けと固定作業をプラットホーム上で行うことができるので、作業者を軌道に下ろす必要がない。そのため、安全で、効率良く、作業を行うことができる。 Due to safety issues, work in orbit is severely restricted. Also, the working environment is not good. Since the fixing member 5 according to the third modification can be attached and fixed on the platform, it is not necessary to lower the operator onto the track. Therefore, the work can be performed safely and efficiently.

（第４の変形例）
支持部材８を埋込パイプ７に固定する固定手段は、上記のものには限定されない。第４の変形例においては、支持部材８の直径を拡大して、支持部材８の外面を埋込パイプ７の内面に当接させる楔部材１６を、支持部材８を埋込パイプ７に固定する固定手段として備える例を示す。 (Fourth modification)
The fixing means for fixing the support member 8 to the embedded pipe 7 is not limited to the above. In the fourth modification, the diameter of the support member 8 is enlarged, and the wedge member 16 that brings the outer surface of the support member 8 into contact with the inner surface of the embedded pipe 7 is fixed to the embedded pipe 7. An example of providing as a fixing means is shown.

図７は、第４の変形例に係る支持部材８の構成を示す斜視図である。図７（Ａ）は支持部材８の全体構成を示す斜視図であり、図７（Ｂ）は支持部材８の下端部の詳細な形状を示す斜視図である。 FIG. 7 is a perspective view showing the configuration of the support member 8 according to the fourth modification. FIG. 7A is a perspective view showing the overall configuration of the support member 8, and FIG. 7B is a perspective view showing a detailed shape of the lower end portion of the support member 8.

図７（Ａ）と図７（Ｂ）に示すように、支持部材８の下端部は、中空円筒状に形成されている。図７（Ｂ）に示すように、支持部材８の下端部の中空円筒状に形成された部位には、４本のスリット８ｃが切り開けられている。スリット８ｃは支持部材８の長さ方向に延びて、支持部材８の下端部の中空円筒状に形成された部位を４枚のパネル８ｄに分割している。 As shown in FIGS. 7A and 7B, the lower end of the support member 8 is formed in a hollow cylindrical shape. As shown in FIG. 7B, four slits 8c are cut in the hollow cylindrical portion of the lower end portion of the support member 8. The slit 8c extends in the length direction of the support member 8 and divides the hollow cylindrical portion of the lower end portion of the support member 8 into four panels 8d.

図７（Ａ）に示すように、支持部材８の下端の中空円筒状に形成された部位には、円錐台形の楔部材１６が挿入される。楔部材１６には貫通穴１６ａが形成されていて、貫通穴１６ａには、ボルト１７が挿通される。なお、楔部材１６の一方の端部の直径は支持部材８の下端の中空円筒状に形成された部位の内径よりも小さくされ、楔部材１６の他方の端部の直径は支持部材８の下端の中空円筒状に形成された部位の内径よりも大きくされている。また、楔部材１６は直径の小さい方の端部を先頭にして、支持部材８に挿入される。 As shown in FIG. 7A, the conical trapezoidal wedge member 16 is inserted into the hollow cylindrical portion at the lower end of the support member 8. A through hole 16a is formed in the wedge member 16, and a bolt 17 is inserted through the through hole 16a. The diameter of one end of the wedge member 16 is smaller than the inner diameter of the hollow cylindrical portion of the lower end of the support member 8, and the diameter of the other end of the wedge member 16 is the lower end of the support member 8. It is made larger than the inner diameter of the portion formed in the hollow cylindrical shape of. Further, the wedge member 16 is inserted into the support member 8 with the end having the smaller diameter at the head.

図８は、第４の変形例に係る固定部材５の構成と作用を説明する図であって、図８（Ａ）は支持部材８を埋込パイプ７に固定する前の状態を、図８（Ｂ）は支持部材８を埋込パイプ７に固定した状態を、それぞれ示す図である。 FIG. 8 is a diagram illustrating the configuration and operation of the fixing member 5 according to the fourth modification, and FIG. 8A shows a state before fixing the support member 8 to the embedded pipe 7. FIG. (B) is a figure which shows the state in which the support member 8 is fixed to the embedded pipe 7, respectively.

図８（Ａ）に示すように、支持部材８の内部には雌ねじ８ｅが形成されている。支持部材８の雌ねじ８ｅが形成された部位は、支持部材８の下端より高い位置にある。そして、支持部材８の内部の、雌ねじ８ｅが形成された部位には、楔部材１６が挿入される空間が形成されている。図８（Ａ）に示す状態においては、楔部材１６は支持部材８の下方に配置されている。楔部材１６にはボルト１７が挿通されていて、ボルト１７の先端は雌ねじ８ｅに螺合されている。 As shown in FIG. 8A, a female screw 8e is formed inside the support member 8. The portion of the support member 8 on which the female screw 8e is formed is located higher than the lower end of the support member 8. A space in which the wedge member 16 is inserted is formed in the portion of the support member 8 where the female screw 8e is formed. In the state shown in FIG. 8A, the wedge member 16 is arranged below the support member 8. A bolt 17 is inserted through the wedge member 16, and the tip of the bolt 17 is screwed into a female screw 8e.

このように、ボルト１７は楔部材１６の下方から楔部材１６に挿通されて、ボルト１７の先端は楔部材１６の上方に突出している。雌ねじ８ｅは支持部材８に固定されていて、雌ねじ８ｅにはボルト１７が螺合されている。 In this way, the bolt 17 is inserted into the wedge member 16 from below the wedge member 16, and the tip of the bolt 17 projects above the wedge member 16. The female screw 8e is fixed to the support member 8, and a bolt 17 is screwed into the female screw 8e.

図８（Ａ）に示す状態において、ボルト１７を回転させて、ボルト１７を雌ねじ８ｅに対して前進させると、楔部材１６は支持部材８の中に引き込まれる。前述したように、楔部材１６は円錐台形をなしているので、楔部材１６は支持部材８の中に引き込まれると、楔部材１６の直径が大きい部位の外側面が支持部材８の内側面に当接して、支持部材８の内側面を押圧する。その結果、図８（Ｂ）に示すように、支持部材８の下端部の外径が拡大されるので、支持部材８の下端部の外側面が埋込パイプ７の内側面に当接して、埋込パイプ７の内側面を押圧する。そのため、支持部材８は、支持部材８の下端部の外面と埋込パイプ７の内面の間で生じる摩擦によって、埋込パイプ７に固定される。なお、前述したように、支持部材８の下端部は、スリット８ｃによって４枚のパネル８ｄに分割されている。そのため、分割されていない場合に比べて、内圧に抵抗しにくくなっている。そのため、楔部材１６によって内圧が加えられると、容易に変形する。 In the state shown in FIG. 8A, when the bolt 17 is rotated to advance the bolt 17 with respect to the female screw 8e, the wedge member 16 is pulled into the support member 8. As described above, since the wedge member 16 has a conical trapezoidal shape, when the wedge member 16 is pulled into the support member 8, the outer surface of the portion having a large diameter of the wedge member 16 becomes the inner surface of the support member 8. It abuts and presses the inner surface of the support member 8. As a result, as shown in FIG. 8B, the outer diameter of the lower end portion of the support member 8 is expanded, so that the outer surface of the lower end portion of the support member 8 comes into contact with the inner side surface of the embedded pipe 7. The inner surface of the embedded pipe 7 is pressed. Therefore, the support member 8 is fixed to the embedded pipe 7 by the friction generated between the outer surface of the lower end portion of the support member 8 and the inner surface of the embedded pipe 7. As described above, the lower end of the support member 8 is divided into four panels 8d by the slit 8c. Therefore, it is less likely to resist internal pressure than when it is not divided. Therefore, when an internal pressure is applied by the wedge member 16, the wedge member 16 easily deforms.

このように、第４の変形例においては、楔部材１６が、支持部材８の下端の中空円筒状に形成された部位の外径を拡大する拡管手段として機能する。また、楔部材１６は、支持部材８を埋込パイプ７に固定する固定手段として機能する。 As described above, in the fourth modification, the wedge member 16 functions as a pipe expanding means for expanding the outer diameter of the portion formed in the hollow cylindrical shape at the lower end of the support member 8. Further, the wedge member 16 functions as a fixing means for fixing the support member 8 to the embedded pipe 7.

（第５の変形例）
第５の変形例においては、ボルト１７が支持部材８の下方から支持部材８に差し込まれる例を示したが、ボルト１７は支持部材８の下方から支持部材８に差し込まれるものには限定されない。第５の変形例においては、ボルト１７が支持部材８の上方から支持部材８に差し込まれる例を示す。 (Fifth variant)
In the fifth modification, the bolt 17 is inserted into the support member 8 from below the support member 8, but the bolt 17 is not limited to the one inserted into the support member 8 from below the support member 8. In the fifth modification, an example in which the bolt 17 is inserted into the support member 8 from above the support member 8 is shown.

図９は、第５の変形例に係る固定部材５の構成と作用を説明する図であって、図９（Ａ）は支持部材８を埋込パイプ７に固定する前の状態を、図９（Ｂ）は支持部材８を埋込パイプ７に固定した状態を、それぞれ示す図である。 9A and 9B are views for explaining the configuration and operation of the fixing member 5 according to the fifth modification, and FIG. 9A shows a state before fixing the support member 8 to the embedded pipe 7. (B) is a figure which shows the state in which the support member 8 is fixed to the embedded pipe 7, respectively.

図９（Ａ）に示すように、第５の変形例においては、ボルト１７は、支持部材８の上方から支持部材８に差し込まれて、雌ねじ８ｅに螺合される。ボルト１７の先端は雌ねじ８ｅの下方に突出して、楔部材１６に挿通されている。また、楔部材１６の下方において、ボルト１７には抜け止め部材１８が嵌合されている。抜け止め部材１８は楔部材１６のボルト１７からの脱落を防ぐ部材であるが、抜け止め部材１８によっては楔部材１６のボルト１７周りの回転は拘束されない。したがって、楔部材１６はボルト１７に対して自由に回転する。 As shown in FIG. 9A, in the fifth modification, the bolt 17 is inserted into the support member 8 from above the support member 8 and screwed into the female screw 8e. The tip of the bolt 17 projects below the female screw 8e and is inserted into the wedge member 16. Further, below the wedge member 16, a retaining member 18 is fitted to the bolt 17. The retaining member 18 is a member that prevents the wedge member 16 from falling off from the bolt 17, but the rotation of the wedge member 16 around the bolt 17 is not restricted by the retaining member 18. Therefore, the wedge member 16 rotates freely with respect to the bolt 17.

このように、ボルト１７は、支持部材８の上方から、支持部材８に差し入れられて、雌ねじ８ｅに螺合される。ボルト１７の先端は雌ねじ８ｅの下方に突出して、楔部材１６に挿通されている。また、雌ねじ８ｅは支持部材８に固定されている。そして、抜け止め部材１８は楔部材１６の下方においてボルト１７に取り付けられて、楔部材１６のボルト１７からの脱落を防いでいる。 In this way, the bolt 17 is inserted into the support member 8 from above the support member 8 and screwed into the female screw 8e. The tip of the bolt 17 projects below the female screw 8e and is inserted into the wedge member 16. Further, the female screw 8e is fixed to the support member 8. The retaining member 18 is attached to the bolt 17 below the wedge member 16 to prevent the wedge member 16 from falling off from the bolt 17.

図９（Ａ）に示す状態において、支承部材９の上方から図示しない工具を差し込んで、ボルト１７を回転させて、ボルト１７を雌ねじ８ｅに対して後退させると、つまりボルト１７を雌ねじ８ｅの上方に向かう方向に移動させると、楔部材１６は支持部材８の中に引き込まれる。その結果、図９（Ｂ）に示すように、支持部材８の下端部の外径が拡大され、支持部材８の下端部の外側面が埋込パイプ７の内面を押圧する。そのため、支持部材８は、支持部材８の下端部の外側面と埋込パイプ７の内面の間で生じる摩擦によって、埋込パイプ７に固定される。 In the state shown in FIG. 9A, a tool (not shown) is inserted from above the bearing member 9, the bolt 17 is rotated, and the bolt 17 is retracted with respect to the female screw 8e, that is, the bolt 17 is moved above the female screw 8e. When moved in the direction toward, the wedge member 16 is pulled into the support member 8. As a result, as shown in FIG. 9B, the outer diameter of the lower end portion of the support member 8 is expanded, and the outer surface of the lower end portion of the support member 8 presses the inner surface of the embedded pipe 7. Therefore, the support member 8 is fixed to the embedded pipe 7 by the friction generated between the outer surface of the lower end portion of the support member 8 and the inner surface of the embedded pipe 7.

このように、第５の変形例においても、楔部材１６が、支持部材８の下端の中空円筒状に形成された部位の外径を拡大する拡管手段として機能する。また、楔部材１６は、支持部材８を埋込パイプ７に固定する固定手段として機能する。 As described above, also in the fifth modification, the wedge member 16 functions as a pipe expanding means for expanding the outer diameter of the portion formed in the hollow cylindrical shape at the lower end of the support member 8. Further, the wedge member 16 functions as a fixing means for fixing the support member 8 to the embedded pipe 7.

なお、前述したように、安全上の問題があるので、軌道上での作業は厳しく制限されている。また、作業環境も良くない。第５の変形例に係る固定部材５は、取り付けと固定作業をプラットホーム上で行うことができるので、作業者を軌道に下ろす必要がない。そのため、安全で、効率良く、作業を行うことができる。 As mentioned above, due to safety issues, work in orbit is severely restricted. Also, the working environment is not good. Since the fixing member 5 according to the fifth modification can be attached and fixed on the platform, it is not necessary to lower the operator onto the track. Therefore, the work can be performed safely and efficiently.

（第６の変形例）
図１０は、第６の変形例に係る固定部材５の構成を示す図であって、図１０（Ａ）は埋込パイプ７の形状を示す斜視図であり、図１０（Ｂ）は支持部材８の形状を示す斜視図である。図１０（Ｃ）は、固定部材５の要部の形状を示す斜視図であり、埋込パイプ７と支持部材８と支承部材９の一部を切り取った状態を示している。 (Sixth variant)
10A and 10B are views showing the configuration of the fixing member 5 according to the sixth modification, FIG. 10A is a perspective view showing the shape of the embedded pipe 7, and FIG. 10B is a support member. It is a perspective view which shows the shape of 8. FIG. 10C is a perspective view showing the shape of the main part of the fixing member 5, and shows a state in which a part of the embedded pipe 7, the support member 8, and the support member 9 is cut off.

図１０（Ａ）に示すように、第６の変形例に係る埋込パイプ７は上端に環状の斜面を有する凹部１９が形成されている。凹部１９の中心軸１９Xは埋込パイプ７の中心軸７Xと同軸にされている。また、図１０（Ｂ）に示すように、第６の変形例に係る支持部材８の上端の、支持部材８を埋込パイプ７に差し込んだ場合に、埋込パイプ７の上端と当接する部位には、円錐台形の凸部２０が形成されている。凸部２０の中心軸２０Xは支持部材８の中心軸８Xと同軸にされている。また、凹部１９の傾斜角と凸部２０の傾斜角は等しくされている。その結果、凹部１９の表面と凸部２０の表面は同形にされている。そのため、図１０（Ｃ）に示すように、凹部１９と凸部２０を互いに面接触させることができる。この状態において、支持部材８は埋込パイプ７に安定して保持される。 As shown in FIG. 10A, the embedded pipe 7 according to the sixth modification has a recess 19 having an annular slope at the upper end thereof. The central shaft 19X of the recess 19 is coaxial with the central shaft 7X of the embedded pipe 7. Further, as shown in FIG. 10B, a portion of the upper end of the support member 8 according to the sixth modification, which comes into contact with the upper end of the embedded pipe 7 when the support member 8 is inserted into the embedded pipe 7. Is formed with a conical trapezoidal convex portion 20. The central axis 20X of the convex portion 20 is coaxial with the central axis 8X of the support member 8. Further, the inclination angle of the concave portion 19 and the inclination angle of the convex portion 20 are made equal to each other. As a result, the surface of the concave portion 19 and the surface of the convex portion 20 have the same shape. Therefore, as shown in FIG. 10C, the concave portion 19 and the convex portion 20 can be brought into surface contact with each other. In this state, the support member 8 is stably held by the embedded pipe 7.

また、凸部２０は円錐台形にされているので、凹部１９と凸部２０を互いに面接触させると、凹部１９の中心軸１９Xと凸部２０の中心軸２０Xが重なる。その結果、埋込パイプ７の中心軸７Xと支持部材８の中心軸８Xが重なる。 Further, since the convex portion 20 has a conical trapezoidal shape, when the concave portion 19 and the convex portion 20 are brought into surface contact with each other, the central axis 19X of the concave portion 19 and the central axis 20X of the convex portion 20 overlap. As a result, the central shaft 7X of the embedded pipe 7 and the central shaft 8X of the support member 8 overlap.

このように、第６の変形例において、凹部１９と凸部２０を互いに面接触させることによって、支持部材８は埋込パイプ７に安定して保持させることができる。また、凹部１９と凸部２０を互いに面接触させることによって、支持部材８を埋込パイプ７に対して同軸に配置することができる。 As described above, in the sixth modification, the support member 8 can be stably held by the embedded pipe 7 by bringing the concave portion 19 and the convex portion 20 into surface contact with each other. Further, the support member 8 can be arranged coaxially with the embedded pipe 7 by bringing the concave portion 19 and the convex portion 20 into surface contact with each other.

（第７の変形例）
図１１は、第７の変形例に係る固定部材５の構成と作用を示す図であって、図１１（Ａ）は支持部材８と支承部材９の外形を示す斜視図であり、図１１（Ｂ）は固定部材５を床板２に固定した状態を示す説明図である。 (7th variant)
11A and 11B are views showing the configuration and operation of the fixing member 5 according to the seventh modification, and FIG. 11A is a perspective view showing the outer shapes of the support member 8 and the support member 9, and FIG. B) is an explanatory view showing a state in which the fixing member 5 is fixed to the floor plate 2.

図１１（Ａ）及び図１１（Ｂ）に示すように、第７の変形例に係る固定部材５は、２本のジャッキボルト２１を備えている。ジャッキボルト２１は、支承部材９に螺合されていて、支承部材９に対して進退する。また、ジャッキボルト２１は支承部材９の上方から、支承部材９に挿通されて、ジャッキボルト２１の先端は支承部材９の下方に突出する。２本のジャッキボルト２１は、支持部材８を間に挟んで、支持部材８の中心軸に対して、軸対象に配置される。固定部材５を床板２に取り付けた状態において、ジャッキボルト２１の一方は、支持部材８よりもプラットホームの外側つまり軌道側に寄った位置に配置され、ジャッキボルト２１の他方は、支持部材８よりもプラットホームの内側に寄った位置に配置される。また、支承部材９におけるジャッキボルト２１の取り付け位置は、支承部材９の中心軸に対して、埋込穴６の半径よりも大きく離隔した位置にある。そのため、ジャッキボルト２１を下降させると、ジャッキボルト２１の先端はプラットホームの床板２の上面に当接する。なお、第７の変形例においては、図１１（Ｂ）に示すように、支承部材９と床板２の間に敷プレート２２が配置されている。そのため、ジャッキボルト２１を下降させると、ジャッキボルト２１の先端は敷プレート２２の上面に当接する。 As shown in FIGS. 11A and 11B, the fixing member 5 according to the seventh modification includes two jack bolts 21. The jack bolt 21 is screwed into the support member 9 and moves back and forth with respect to the support member 9. Further, the jack bolt 21 is inserted into the support member 9 from above the support member 9, and the tip of the jack bolt 21 projects below the support member 9. The two jack bolts 21 are arranged symmetrically with respect to the central axis of the support member 8 with the support member 8 sandwiched between them. In the state where the fixing member 5 is attached to the floor plate 2, one of the jack bolts 21 is arranged outside the platform, that is, closer to the track side than the support member 8, and the other of the jack bolts 21 is located closer to the track side than the support member 8. It is located closer to the inside of the platform. Further, the mounting position of the jack bolt 21 on the bearing member 9 is located at a position larger than the radius of the embedding hole 6 with respect to the central axis of the bearing member 9. Therefore, when the jack bolt 21 is lowered, the tip of the jack bolt 21 comes into contact with the upper surface of the floor plate 2 of the platform. In the seventh modification, as shown in FIG. 11B, the floor plate 22 is arranged between the support member 9 and the floor plate 2. Therefore, when the jack bolt 21 is lowered, the tip of the jack bolt 21 comes into contact with the upper surface of the floor plate 22.

さて、ホームドア装置１は、乗降客による押し圧力、台風や列車風による風力など、ホーム側−軌道側の方向に外力を受ける。この時、固定部材５には大きな曲げ応力が生じる。特に、支持部材８と支承部材９の接合部に曲げ応力が生じる。第７の変形例に係る固定部材５においては、ホームドア装置１が外力を受けて、固定部材５がホーム側−軌道側の方向に倒れようとする場合に、固定部材５が倒れる側に配置されたジャッキボルト２１に、敷プレート２２を介して、床板２から支持反力が加わる。その結果、支承部材９から支持部材８に伝わる外力の一部が、支承部材９から床板２に伝わるので、支持部材８と支承部材９の接合部に生じる曲げ応力が緩和される。 By the way, the platform door device 1 receives an external force in the direction of the platform side-orbit side, such as pushing pressure by passengers, wind power by a typhoon or train wind. At this time, a large bending stress is generated in the fixing member 5. In particular, bending stress is generated at the joint between the support member 8 and the support member 9. In the fixing member 5 according to the seventh modification, when the platform door device 1 receives an external force and the fixing member 5 tries to fall in the direction of the home side-orbital side, the fixing member 5 is arranged on the side where the fixing member 5 falls. A supporting reaction force is applied to the jack bolt 21 from the floor plate 2 via the floor plate 22. As a result, a part of the external force transmitted from the support member 9 to the support member 8 is transmitted from the support member 9 to the floor plate 2, so that the bending stress generated at the joint portion between the support member 8 and the support member 9 is relaxed.

なお、第７の変形例において、敷プレート２２は必須の構成要素ではない。固定部材５は敷プレート２２を備えないものであっても良い。固定部材５は、ジャッキボルト２１の先端が床板２の上面に直接、当接するものであっても良い。 In the seventh modification, the floor plate 22 is not an essential component. The fixing member 5 may not include the floor plate 22. The fixing member 5 may have the tip of the jack bolt 21 directly in contact with the upper surface of the floor plate 2.

以上、説明したように、床板２に円筒状の埋込穴６を穿設するだけで、上記の実施の形態と各変形例に係る固定部材５の取り付け準備が完了する。そして、埋込穴６に固定部材５を埋め込むだけで基礎構造の設置が完了する。そのため、ホームドア装置１の設置工事に掛かる作業時間が短縮される。 As described above, the preparation for mounting the fixing member 5 according to the above-described embodiment and each modification is completed only by drilling the cylindrical embedded hole 6 in the floor plate 2. Then, the installation of the foundation structure is completed only by embedding the fixing member 5 in the embedding hole 6. Therefore, the work time required for the installation work of the platform door device 1 is shortened.

なお、本発明の技術的範囲は上記の実施の形態と各変形例によっては限定されない。本発明は、特許請求の範囲に記載された技術的思想の限りにおいて、自由に、応用、及び変形して実施することができる。 The technical scope of the present invention is not limited to the above-described embodiment and each modification.

The embedding hole 6 may be one that does not penetrate the floor plate 2, that is, one that has a bottom. For example, in the third and fifth modifications, that is, the examples shown in FIGS. 6 and 9, when fixing the support member 8 to the embedded pipe 7, a tool is inserted from above the fixing member 5. Since it can be formed, the embedding hole 6 may not penetrate the floor plate 2.

上記の実施の形態において、コアドリルを使って埋込穴６を穿設する例を示したが、埋込穴６はコアドリルによって穿設された物には限定されない。また、埋込穴６を高精度に穿設できる場合には、埋込パイプ７を省略しても良い。つまり、固定部材５は埋込パイプ７を備えないものであっても良い。 In the above embodiment, an example of drilling the embedded hole 6 using a core drill has been shown, but the embedded hole 6 is not limited to the one drilled by the core drill. Further, if the embedding hole 6 can be drilled with high accuracy, the embedding pipe 7 may be omitted. That is, the fixing member 5 may not include the embedded pipe 7.

Not limited to. It is sufficient if the convex portion 20 and the concave portion 19 have a shape that fits each other. As long as the shapes are fitted to each other, the shapes of the convex portion 20 and the concave portion 19 are arbitrarily selected. The convex portion 20 and the concave portion 19 may be formed of a flat surface or a curved surface.

支承部材９が備えるボルト１０の本数は限定されない。支承部材９はボルト１０を１本だけ備えるものであっても良いし、３本、４本、あるいは更に多数のボルト１０を備えるもものであっても良い。 The number of bolts 10 included in the bearing member 9 is not limited. The bearing member 9 may include only one bolt 10, three, four, or even a large number of bolts 10.

第４及び第５の変形例において、支持部材８の下端の楔部材１６によって拡管される部位に、スリット８ｃを切り開けて、該部位を４枚のパネル８ｄに分割する例を示したが、かかる構成は必須ではない。支持部材８はスリット８ｃが切り開けられていなくても良い。 In the fourth and fifth modifications, an example is shown in which a slit 8c is cut in a portion expanded by the wedge member 16 at the lower end of the support member 8 and the portion is divided into four panels 8d. The configuration is not mandatory. The support member 8 does not have to have the slit 8c cut open.

なお、上記の実施の形態と各変形例においては、埋込パイプ７の断面形を円形とする例を示したが、埋込パイプ７の断面形は円形には限定されない。 In the above-described embodiment and each modification, an example in which the cross-sectional shape of the embedded pipe 7 is circular is shown, but the cross-sectional shape of the embedded pipe 7 is not limited to a circular shape.

各図面において図示された、ホームドア装置１と固定部材５の具体的な形状及び寸法は例示である。本発明の技術的範囲は各図面に図示された、ホームドア装置１と固定部材５の具体的な形状及び寸法によっては限定されない。特に、ホームドア装置１は、１枚扉を備えるものには限定されない。ホームドア装置１は、多段扉を備えるものであっても良い。 The specific shapes and dimensions of the platform door device 1 and the fixing member 5 shown in each drawing are examples.
