Embodiment 1 FIG.
1 is a cross-sectional view showing a basic structure of a movable home fence apparatus 1 according to Embodiment 1 of the present invention.
The movable platform fence device 1 is installed along a side edge on the platform 4 and forms a fence with a train that stops at a fixed position on a track that extends to the side of the platform 4. The safety of passengers is ensured.
The platform 4 is formed in a substantially T-shaped cross section supported on the standing leg portion, and the side edge portion of the platform 4 protrudes to the line side extending to the side of the platform 4.
The platform 4 includes a slab portion 6 made of reinforced concrete and a panel portion 5 bonded to the upper surface of the slab portion 6 by a mortar portion 7 and embedded with anti-slip and tiles.

可動ホーム柵装置１は、戸袋柵と、この戸袋柵よりプラットホーム４の側縁に沿って出没する開閉可能な乗降扉とから構成されている。この可動ホーム柵装置１は、プラットホーム４側から線路側を視たときに、戸袋柵の左右の両側の下部に矩形状の脚部２がそれぞれ設けられている。可動ホーム柵装置１は、一対の脚部２にそれぞれ４本（線路側２本、反線路側２本）の取付ボルト３を螺着することで、プラットホーム４に固定されている。   The movable platform fence device 1 is composed of a door pocket fence and an openable / closable entrance door that appears and disappears along the side edge of the platform 4 from the door fence. The movable platform fence device 1 is provided with rectangular legs 2 at the lower portions on both the left and right sides of the door pocket fence when the track side is viewed from the platform 4 side. The movable platform fence device 1 is fixed to the platform 4 by screwing four mounting bolts 3 (two on the track side and two on the non-track side) to the pair of leg portions 2 respectively.

プラットホーム４には、それぞれの取付ボルト３が螺着する位置に対応して取付穴８が穿設されている。この取付穴８の深さは、上面からパネル部５及びモルタル部７を貫通し、スラブ部６の奥まで達しており、可動ホーム柵装置１に対する平面方向の荷重にプラットホーム４が耐え得る強度が確保される深さである。
例えば、パネル部５の厚さ３０ｍｍ、モルタル部７の厚さ１０ｍｍとして、スラブ部６に必要な強度を確保できる深さを７０ｍｍとすると、取付穴８の深さは、１１０ｍｍとなる。
この取付穴８には、図２に示す接着系雌ねじアンカー（以下、雌ねじアンカーと略称する）１０が充填剤９で固定されて埋設されている。 Mounting holes 8 are formed in the platform 4 corresponding to positions where the respective mounting bolts 3 are screwed. The depth of the mounting hole 8 penetrates the panel portion 5 and the mortar portion 7 from the upper surface and reaches the back of the slab portion 6, and has a strength that the platform 4 can withstand the load in the plane direction on the movable home fence device 1. The depth to be secured.
For example, when the thickness of the panel portion 5 is 30 mm and the thickness of the mortar portion 7 is 10 mm and the depth capable of securing the strength required for the slab portion 6 is 70 mm, the depth of the mounting hole 8 is 110 mm.
An adhesive female thread anchor (hereinafter abbreviated as female thread anchor) 10 shown in FIG. 2 is fixed and embedded in the mounting hole 8 with a filler 9.

この雌ねじアンカー１０は、内壁面に雌ねじ１４が形成された円筒形状のアンカー本体３０と、このアンカー本体３０の上部にカシメ等（溶接または接着でも可）で固着された円板状の受板１３とを備えている。雌ねじ１４の深さは、必ずしもアンカー本体３０の下端部まで必要としない。
受板１３は、可動ホーム柵装置１の荷重を支持するとともに、可動ホーム柵装置１の脚部２を取付ボルト３を用いてプラットホーム４に固定する際に、取付ボルト３の締付力がパネル部５、モルタル部７に及び、パネル部５が割れたり、モルタル部７から剥がれたりするのを極力低減させるためである。
アンカー本体３０は、スラブ部６と充填剤９を介して強固に接着できるように外周面が凹凸面である固着部１１と、この固着部１１と受板１３との間に設けられた円周平滑面である首部１２とから構成されている。
この雌ねじアンカー１０の首部１２の上下方向の長さは、パネル部５の厚さにモルタル部７の厚さを加えたよりも長い。例えば、パネル部５の厚さ３０ｍｍ、モルタル部７の厚さ１０ｍｍであれば４０ｍｍを超える長さである。これは、雌ねじアンカー１０を取付穴８から引き抜く方向の力が加わったときに、強度的に脆弱なパネル部５、モルタル部７に過度に加わらないようにするためである。 The internal thread anchor 10 includes a cylindrical anchor body 30 having an internal thread 14 formed on an inner wall surface, and a disk-shaped receiving plate 13 secured to the upper portion of the anchor body 30 by caulking or the like (which may be welded or bonded). And. The depth of the female screw 14 is not necessarily required up to the lower end portion of the anchor main body 30.
The support plate 13 supports the load of the movable home fence device 1 and, when the leg portion 2 of the movable home fence device 1 is fixed to the platform 4 using the mounting bolt 3, the fastening force of the mounting bolt 3 is a panel. This is because the panel portion 5 is cracked or peeled off from the mortar portion 7 as much as possible.
The anchor main body 30 has a fixed portion 11 having an uneven outer peripheral surface and a circumference provided between the fixed portion 11 and the receiving plate 13 so that the anchor body 30 can be firmly bonded via the slab portion 6 and the filler 9. The neck portion 12 is a smooth surface.
The length of the neck portion 12 of the female screw anchor 10 in the vertical direction is longer than the thickness of the panel portion 5 plus the thickness of the mortar portion 7. For example, if the thickness of the panel part 5 is 30 mm and the thickness of the mortar part 7 is 10 mm, the length exceeds 40 mm. This is to prevent excessive application of strength to the panel portion 5 and the mortar portion 7 when a force in the direction of pulling out the female screw anchor 10 from the mounting hole 8 is applied.

次に、可動ホーム棚装置１をプラットホーム４に固定する可動ホーム棚装置１の基礎工事方法について説明する。
最初に、可動ホーム柵装置１の脚部２が置かれるプラットホーム４の上面に、４箇所の必要深さ（前記例では１１０ｍｍ）の取付穴８を電動ドリル等を用いて穿設し、取付穴８に残った切り屑を除去する。この取付穴８の中心線は、脚部２に形成された取付ボルト３の貫通穴（図示せず）の中心線と一致している。なお、脚部２は、可動ホーム柵装置１の戸袋柵の下部の左右両側に一対設けられているので、一つの可動ホーム柵装置１に対して、プラットホーム４には、８箇所の取付穴８が形成される。
この取付穴８は、雌ねじアンカー１０の固着部１１、首部１２の外径よりも少し大きい直径の穴である。 Next, the foundation construction method of the movable home shelf apparatus 1 that fixes the movable home shelf apparatus 1 to the platform 4 will be described.
First, four mounting holes 8 having a required depth (110 mm in the above example) are drilled on the upper surface of the platform 4 on which the legs 2 of the movable platform fence device 1 are placed by using an electric drill or the like. The remaining chips in 8 are removed. The center line of the mounting hole 8 coincides with the center line of a through hole (not shown) of the mounting bolt 3 formed in the leg portion 2. Since the leg portions 2 are provided as a pair on the left and right sides of the lower portion of the door fence of the movable home fence device 1, eight mounting holes 8 are provided on the platform 4 with respect to one movable home fence device 1. Is formed.
The mounting hole 8 is a hole having a diameter slightly larger than the outer diameters of the fixing portion 11 and the neck portion 12 of the female screw anchor 10.

次に、この取付穴８の中に液状の充填剤９を必要量注入してから、雌ねじアンカー１０の固着部１１及び首部１２を挿入する。このとき、受板１３は、プラットホーム４のパネル部５の上面から離間している。
充填剤９が固まって雌ねじアンカー１０の固着部１１がプラットホーム４のスラブ部６と接着したら、可動ホーム柵装置１の脚部２の貫通孔の中心線と雌ねじアンカー１０の雌ねじ穴１４の中心線とが一致するように、可動ホーム棚装置１をプラットホーム４上に載置する。
この後、脚部２の貫通孔を貫通した取付ボルト３を雌ねじ穴１４に螺着して、可動ホーム棚装置１をプラットホーム４上に固定する。 Next, after a required amount of liquid filler 9 is injected into the mounting hole 8, the fixing portion 11 and the neck portion 12 of the female screw anchor 10 are inserted. At this time, the receiving plate 13 is separated from the upper surface of the panel portion 5 of the platform 4.
When the filler 9 is solidified and the fixing portion 11 of the female screw anchor 10 is bonded to the slab portion 6 of the platform 4, the center line of the through hole of the leg portion 2 of the movable platform fence device 1 and the center line of the female screw hole 14 of the female screw anchor 10 are obtained. The movable home shelf device 1 is placed on the platform 4 so that.
Thereafter, the mounting bolt 3 penetrating the through hole of the leg portion 2 is screwed into the female screw hole 14 to fix the movable home shelf device 1 on the platform 4.

このように、従来のもののようにプラットホーム４のパネル部５やモルタル部７を除去した嵌合溝やスラブ部６を貫通する貫通孔の加工は不要であり、電動ドリル等を使用して簡単に短時間で取付穴８を形成することができ、可動ホーム柵装置１をプラットホーム４の上面に簡単で短時間で据付けることができる。
また、雌ねじアンカー１０の受板１３は、プラットホーム４のパネル部５の上面から離間しており、可動ホーム柵装置１の重量や脚部２を取付ボルト３で締め付けた際の荷重等の負荷は受板１３で受ける。従って、プラットホーム４に可動ホーム柵装置１の据付けた後の負荷は、パネル部５に加わることが無いため、パネル部５が割れたり、モルタル部７から剥がれたりするようなことを防止することができる。 Thus, it is not necessary to process the fitting groove from which the panel portion 5 and the mortar portion 7 of the platform 4 are removed and the through-hole penetrating the slab portion 6 as in the prior art, and it is easy to use an electric drill or the like The mounting hole 8 can be formed in a short time, and the movable home fence apparatus 1 can be easily and quickly installed on the upper surface of the platform 4.
Further, the receiving plate 13 of the female screw anchor 10 is separated from the upper surface of the panel portion 5 of the platform 4, and the load of the movable home fence device 1 and the load when the leg portion 2 is tightened with the mounting bolt 3 are It is received by the receiving plate 13. Therefore, since the load after the movable platform fence apparatus 1 is installed on the platform 4 is not applied to the panel unit 5, it is possible to prevent the panel unit 5 from being broken or peeled off from the mortar unit 7. it can.

さらに、施工中の作業時間の関係で雌ねじアンカー１０を挿入するまでの作業と、可動ホーム柵装置１の脚部２を取付ボルト３で雌ねじアンカー１０に取付ける作業を別の日に実施する場合がある。
このような場合にも、雌ねじアンカー１０は、プラットホーム４のパネル部５の上面から薄い円板状の受板１３のみが突出するだけであり、段差がほとんど生じないように養生できるため、例えば雌ねじアンカー１０の周りに囲いを設置して乗客が近づかないようにするといった余分な作業は不要でありとともに、養生中の営業運転時における乗客のつまずきや転倒の発生を抑制することができる。 Furthermore, there is a case where the work until the female screw anchor 10 is inserted due to the work time during construction and the work of attaching the leg 2 of the movable home fence device 1 to the female screw anchor 10 with the mounting bolt 3 are performed on different days. is there.
Even in such a case, the female screw anchor 10 can be cured so that only a thin disc-shaped receiving plate 13 protrudes from the upper surface of the panel portion 5 of the platform 4 and hardly causes a step. Extra work such as installing an enclosure around the anchor 10 to prevent the passenger from approaching is not necessary, and it is possible to suppress the occurrence of a trip or fall of the passenger during commercial operation during curing.

また、プラットホーム４の下側空間は、可動ホーム柵装置１の据付け作業に関わりが無いので、プラットホーム４の下側空間に例えば補強用鋼材やラック、ケーブルなどがある場合でも施工することができる。   Further, since the lower space of the platform 4 is not related to the installation work of the movable platform fence device 1, it can be constructed even when there is a reinforcing steel material, a rack, a cable, or the like in the lower space of the platform 4.

実施の形態２．
一般に、可動ホーム柵装置１は、プラットホーム４上の側縁に沿って多数設置されるため、隣接して設置される可動ホーム柵装置１との高さ調整や傾き調整を高精度に実施する必要があり、据付け作業時間のうち調整作業にも多くの時間を要する。
この高さ調整や傾き調整を簡単に高精度に実施できるようにしたものが、図３に示した
可動ホーム柵装置１の基礎構造である。 Embodiment 2. FIG.
In general, since a large number of movable home fence devices 1 are installed along the side edges on the platform 4, it is necessary to perform height adjustment and inclination adjustment with the movable home fence device 1 installed adjacently with high accuracy. Therefore, it takes much time for the adjustment work among the installation work time.
The basic structure of the movable home fence apparatus 1 shown in FIG. 3 is one in which the height adjustment and the inclination adjustment can be easily performed with high accuracy.

図３は、この発明の実施の形態２の可動ホーム柵装置１の基礎構造を示す断面図、図４は図３のベース板１５の斜視図である。
この実施の形態２の可動ホーム柵装置１の基礎構造では、一対の脚部２用の取付ボルト１８が可動ホーム柵装置１の脚部２を貫通し、ベース板１５のねじ穴１６に螺着して、脚部２がベース板１５に固定されている。このベース板１５には取付穴１７がねじ穴１６の両側にそれぞれ形成されている。
ベース板１５と雌ねじアンカー１０の受板１３との間には、図５に示す六角ナット状の調整具１９及び図６に示す複数枚のライナー２０が介在している。ライナー２０には、縁部に切欠き２１が形成されている。
ベース板１５用の取付ボルト３Ａは、調整具１９の穴に螺合し、頭部がベース板１５よりも少し離間して雌ねじアンカー１０に螺着されている。この離間距離分だけ、可動ホーム柵装置１を上方向に移動調整可能である。
他の構成は、実施の形態１の可動ホーム柵装置１の基礎構造と同じである。 FIG. 3 is a sectional view showing the basic structure of the movable platform fence device 1 according to Embodiment 2 of the present invention, and FIG. 4 is a perspective view of the base plate 15 of FIG.
In the basic structure of the movable home fence apparatus 1 according to the second embodiment, the mounting bolts 18 for the pair of leg portions 2 penetrate the leg parts 2 of the movable home fence apparatus 1 and are screwed into the screw holes 16 of the base plate 15. The leg 2 is fixed to the base plate 15. Mounting holes 17 are formed in the base plate 15 on both sides of the screw holes 16, respectively.
Between the base plate 15 and the receiving plate 13 of the female screw anchor 10, a hexagonal nut-shaped adjuster 19 shown in FIG. 5 and a plurality of liners 20 shown in FIG. 6 are interposed. The liner 20 has a notch 21 at the edge.
The mounting bolt 3 </ b> A for the base plate 15 is screwed into the hole of the adjustment tool 19, and the head is screwed to the female screw anchor 10 with a little distance from the base plate 15. The movable home fence apparatus 1 can be moved and adjusted upward by this distance.
Other configurations are the same as the basic structure of the movable home fence apparatus 1 according to the first embodiment.

次に、可動ホーム柵装置１の高さ、傾きの調整の方法について説明する。
先ず、ベース板１５を調整具１９を介在させて取付ボルト３Ａにより少し余裕のある状態で雌ねじアンカー１０に仮取付けし、このベース板１５に取付ボルト１８で可動ホーム柵装置１の脚部２を取付ける。
この状態で調整具１９を回転させると、調整具１９は取付ボルト３Ａに螺着しているので、上下方向に動く。
この調整具１９を回転させ、上下方向に移動させることで、ベース板１５も上下方向に移動し、ベース板１５に脚部２が取付ボルト１８で固定された可動ホーム柵装置１も上下方向に移動する。
この調整具１９は、一つの可動ホーム柵装置１に対して８箇備えているので、各調整具１９を回転させることで、可動ホーム柵装置１の高さ、傾きを調整する。
高さ、傾き調整ができたら必要枚数のライナー２０を雌ねじアンカー１０の受板１３と調整具１９の間に挿入して、高さ、傾きの微調整を行った後、調整具１９で締付固定する。
この調整具１９の締付により高さが若干下がるため、ライナー２０を入れる際にはその分を見越した高さを調整具１９で調整しておけばよい。
また、雌ねじアンカー１０の受板１３及び調整具１９の各面積は、ライナー２０を挿入して締め付けた場合にライナー２０が変形しない十分な大きさにしている。
このようにして高さが調整できたら、最後に取付ボルト３Ａを締め付けてベース板１５を固定する。 Next, a method for adjusting the height and inclination of the movable home fence apparatus 1 will be described.
First, the base plate 15 is temporarily attached to the female screw anchor 10 with a mounting bolt 3A with the adjusting tool 19 interposed therebetween, and the leg 2 of the movable home fence apparatus 1 is attached to the base plate 15 with the mounting bolt 18. Install.
When the adjusting tool 19 is rotated in this state, the adjusting tool 19 is screwed to the mounting bolt 3A, and thus moves in the vertical direction.
By rotating the adjustment tool 19 and moving it in the vertical direction, the base plate 15 is also moved in the vertical direction, and the movable home fence device 1 in which the legs 2 are fixed to the base plate 15 with mounting bolts 18 is also moved in the vertical direction. Moving.
Since eight adjusters 19 are provided for one movable home fence device 1, the height and inclination of the movable home fence device 1 are adjusted by rotating each adjuster 19.
When the height and inclination can be adjusted, the necessary number of liners 20 are inserted between the receiving plate 13 of the female screw anchor 10 and the adjustment tool 19, fine adjustment of the height and inclination is performed, and then tightened with the adjustment tool 19. Fix it.
Since the height is slightly lowered by the tightening of the adjusting tool 19, when the liner 20 is inserted, the height in anticipation of that amount may be adjusted by the adjusting tool 19.
In addition, the areas of the receiving plate 13 and the adjusting tool 19 of the female screw anchor 10 are sufficiently large so that the liner 20 is not deformed when the liner 20 is inserted and tightened.
When the height can be adjusted in this way, finally the mounting bolt 3A is tightened to fix the base plate 15.

このように、この実施の形態の可動ホーム柵装置１の基礎構造は、１脚部２当たり、取付ボルト３Ａは４箇所であり、可動ホーム柵装置１の脚部２は、プラットホーム４に向かって左右の両側２箇所にあるため、合計８箇所の調整具１９を回して高さ調整することで、簡単に短時間で可動ホーム柵装置１の据え付け高さと傾きを調整できる。
なお、図６に示すライナー２０は切欠き２１が２箇所設けられたものを示しているが、調整時の必要に応じて切欠き２１が１箇所で薄板の面積も小さいものが使用される。 Thus, the basic structure of the movable platform fence apparatus 1 according to this embodiment has four mounting bolts 3A per leg 2, and the legs 2 of the movable platform fence apparatus 1 are directed toward the platform 4. Since there are two places on both the left and right sides, the installation height and inclination of the movable home fence device 1 can be easily adjusted in a short time by turning the total of the eight adjustment tools 19 to adjust the height.
In addition, although the liner 20 shown in FIG. 6 has shown what the two notches 21 were provided in, the thing which has the notch 21 and the area of a thin plate small is used as needed at the time of adjustment.

なお、この実施の形態２では、ベース板１５を使用する場合について説明したが、ベース板１５は必ずしも必要なものではなく、雌ねじアンカー１０の受板１３と可動ホーム柵装置１の脚部２との間に調整具を設けるようにすることで、ベース板１５が無くても可動ホーム柵装置１の取付高さと傾きを調整できる。   In addition, in this Embodiment 2, although the case where the base plate 15 was used was demonstrated, the base plate 15 is not necessarily required, the receiving plate 13 of the internal thread anchor 10, the leg part 2 of the movable home fence apparatus 1, and By providing an adjustment tool between the two, the mounting height and inclination of the movable home fence apparatus 1 can be adjusted without the base plate 15.

なお、上記実施の形態１，２では、何れも雌ねじアンカー１０は、首部１２の上部に円板状の受板１３が設けられているが、円板状に限定されるものではなく、四角形や六角形など他の形状であってもよい。
また、取付ボルト３，３Ａ，１８の本数やサイズは必要強度等により適宜決定されるもので、上記各実施１，２の形態に限定されるものではない。
また、１枚の受板１３に対して、複数個（例えば２個または４個）のアンカー本体３０を固着した構造にすれば、複数個のアンカー本体３０の各挿入作業が一回の挿入作業で済み、プラットホーム４の取付穴８にアンカー本体３０を挿入する作業の回数を減らすことができ、挿入作業時間を削減することができる。
また、受板１３が拡大することで、挿入作業時の受板１３の水平調整等も簡単化される。 In each of the first and second embodiments, the female thread anchor 10 is provided with the disc-shaped receiving plate 13 on the upper portion of the neck portion 12, but is not limited to the disc shape. Other shapes such as a hexagon may be used.
Further, the number and size of the mounting bolts 3, 3 </ b> A, 18 are appropriately determined depending on the required strength and the like, and are not limited to the embodiments 1 and 2 described above.
Further, if a plurality of (for example, two or four) anchor main bodies 30 are fixed to one receiving plate 13, each insertion operation of the plurality of anchor main bodies 30 is performed once. The number of operations for inserting the anchor main body 30 into the mounting hole 8 of the platform 4 can be reduced, and the insertion operation time can be reduced.
Further, since the receiving plate 13 is enlarged, the horizontal adjustment of the receiving plate 13 during the insertion operation is simplified.
