Description

本発明は、路盤コンクリート上に配列されて上面に鉄道レールが締結される軌道スラブと、上記軌道スラブの位置決め用に路盤コンクリートから立ち上げられた円柱形状の突起
との間に填充材を充填するための填充材収容体に関するものである。
In the present invention, a filler is filled between a track slab arranged on the roadbed concrete and a railroad rail is fastened to the upper surface thereof, and a cylindrical protrusion raised from the roadbed concrete for positioning the track slab. It relates to a filler container for the purpose.

鉄道用の軌道としてスラブ軌道が広く採用されている。スラブ軌道は、路盤コンクリートの上にセメントアスファルトモルタル層を介してコンクリートの軌道スラブが軌道の方向に配列され、その上にレールが締結されている。
配列された隣り合う軌道スラブの対向部には路盤コンクリートから円柱形状の突起が立ち上げられており、軌道スラブの端面に形成されたほぼ半円形の凹部の円筒曲面が突起の外周面と間隔を開けて対向している。そして、突起の外周面と軌道スラブに形成された凹状の円筒曲面との間に填充材を充填し、軌道スラブの位置を拘束するものとなっている。
The slab track is widely used as a track for railways. In the slab track, concrete track slabs are arranged on the roadbed concrete via a cement asphalt mortar layer in the direction of the track, and rails are fastened on the track slabs.
Cylindrical protrusions are raised from the roadbed concrete at the opposite parts of the adjacent track slabs arranged, and the cylindrical curved surface of the substantially semicircular recess formed on the end face of the track slabs is spaced from the outer peripheral surface of the protrusions. Open and face each other. Then, a filling material is filled between the outer peripheral surface of the protrusion and the concave cylindrical curved surface formed on the track slab, and the position of the track slab is constrained.

スラブ軌道と突起との間への填充材の充填は、填充用の袋体を装着してこの袋体の内側に填充材を注入する方法が採用されている。広く用いられている従来の袋体は不織布からなる上方が開放されたものであり、填充材の充填時にしわが生じたり、よじれたりするのを防ぐために、あらかじめ突起の周面及び軌道スラブの凹状の円筒曲面に接着して用いている。このため、袋体を接着するのに多くの作業時間を要するとともに作業者の熟練度によって作業効率が大きく変動することになる。 For filling the filling material between the slab track and the protrusion, a method is adopted in which a filling bag body is attached and the filling material is injected into the inside of the bag body. The widely used conventional bag body is made of non-woven fabric and has an open upper part. In order to prevent wrinkles and kinks when filling the filler, the peripheral surface of the protrusion and the concave shape of the track slab are formed in advance. It is used by adhering to the cylindrical curved surface of. For this reason, it takes a lot of work time to bond the bag body, and the work efficiency varies greatly depending on the skill level of the worker.

このような問題を解決するために、特許文献1から特許文献3までには、突起と軌道スラブとの間への装着を容易とする袋体が提案されている。
特許文献1及び特許文献2に記載されている填充層形成用袋体は、突起と軌道スラブとの間に装着される袋体の円筒形状部分にX状の芯体を縫い付け、自立が可能としたものである。そして、2つの円筒形状部分の上部、底部及び周方向の端部を所定の間隔で連結して袋体としたものである。
また、特許文献3に記載の填充層形成用袋体は、突起の外周面及び軌道スラブの凹状の曲面と対向する円筒形状部分を、自立が可能な剛性及び通液性を有する樹脂製の不織布で形成したものである。これらの円筒形状部分は,特許文献1及び特許文献2に記載されている填充層形成用袋体と同様に、上部、底部及び周方向の端部が所定の間隔で連結されている。
In order to solve such a problem, Patent Documents 1 to 3 propose a bag body that can be easily attached between the protrusion and the track slab.
The filling layer forming bag described in Patent Document 1 and Patent Document 2 can stand on its own by sewing an X-shaped core body to the cylindrical portion of the bag body mounted between the protrusion and the track slab. It is the one. Then, the upper portion, the bottom portion, and the end portions in the circumferential direction of the two cylindrical portions are connected at predetermined intervals to form a bag body.
Further, the bag for forming a filling layer described in Patent Document 3 is a resin non-woven fabric having rigidity and liquid permeability capable of allowing the outer peripheral surface of the protrusion and the cylindrical portion facing the concave curved surface of the track slab to stand on its own. It is formed by. Similar to the filling layer forming bag described in Patent Document 1 and Patent Document 2, the top, bottom and circumferential ends of these cylindrical portions are connected at predetermined intervals.

しかしながら、上記特許文献に記載されている従来の技術では次のような解決が望まれる課題がある。
コンクリートからなる軌道スラブ及び突起は、それぞれ鋼型枠を用いてコンクリートが打設され、形状および寸法は正確に製作される。しかし、路盤コンクリートに一体となるように突起が形成された後、所定の形状に形成された軌道スラブを配列したときに、対向する突起の外周面と軌道スラブに形成された凹部の円筒曲面との間隔には誤差が生じることがある。
However, the conventional techniques described in the above patent documents have problems for which the following solutions are desired.
The track slabs and protrusions made of concrete are each cast with concrete using a steel formwork, and the shape and dimensions are accurately manufactured. However, after the protrusions are formed so as to be integrated with the roadbed concrete, when the track slabs formed in a predetermined shape are arranged, the outer peripheral surface of the facing protrusions and the cylindrical curved surface of the recess formed in the track slab are formed. There may be an error in the interval between.

このように突起と軌道スラブとの間隔に誤差があると、上記特許文献に記載の填充層形成用袋体を装着して填充材を注入したときに自立した円筒形状部分は、それぞれ突起の外周面又は軌道スラブの凹状の円筒曲面に押し付けられる。ことため突起と軌道スラブとの間隔が所定の幅より大きいときには円筒形状部分が互いに引っ張られ、間隔が小さいと互いに近接した状態となる。このため、袋体にしわが生じたり、よじれたりして充填した填充材と突起又は軌道スラブとの密着性が損なわれることがある。また、上面を平坦に仕上げることが難しくなり、手直し等が必要となる。特に、軌道に横断勾配があるときには、装着した袋体の周方向の両端部で高さが異なり、低い位置では充填した填充材が膨れ上がった形状になり、手直しを行うことになる。 If there is an error in the distance between the protrusion and the track slab, the cylindrical portion that stands on its own when the filling layer forming bag described in the above patent document is attached and the filling material is injected will be the outer circumference of each protrusion. It is pressed against the concave cylindrical curved surface of a surface or track slab. Therefore, when the distance between the protrusion and the track slab is larger than a predetermined width, the cylindrical portions are pulled from each other, and when the distance is small, they are in close proximity to each other. For this reason, the bag body may be wrinkled or twisted to impair the adhesion between the filled filler and the protrusion or track slab. In addition, it becomes difficult to finish the upper surface flat, and it is necessary to rework. In particular, when the track has a transverse gradient, the heights differ at both ends in the circumferential direction of the attached bag body, and at a low position, the filled filler has a bulging shape, which requires rework.

本発明は、上記のような事情に鑑みてなされたものであり、その目的は、路盤コンクリートから立ち上げられた突起と軌道スラブとの間に填充材を効率よく充填するとともに、突起及び軌道スラブに良好な密着性を有するように充填することができる填充材収容体を提供することである。 The present invention has been made in view of the above circumstances, and an object of the present invention is to efficiently fill a filling material between a protrusion raised from roadbed concrete and a track slab, and to fill the protrusion and the track slab. It is an object of the present invention to provide a filler container that can be filled so as to have good adhesion to the concrete.

上記課題を解決するために、請求項1に係る発明は、 路盤コンクリート上に配列されて上面に鉄道レールが締結される軌道スラブと、前記路盤コンクリートから立ち上げられた円柱形状の突起との間の円弧状の間隙に填充材を充填するための填充材収容体であって、 前記填充材がにじみ出す多数の小孔を有する薄板材からなり、前記突起の周面に沿った円筒曲面部を含み、該円筒曲面部の形状を維持して自立する第1部材と、 前記填充材がにじみ出す多数の小孔を有する薄板材からなり、前記突起の周面と間隔を開けて対向するように形成された前記軌道スラブの凹状の円筒曲面に沿った円筒曲面部を含み、該円筒曲面部の形状を維持して自立する第2部材と、 伸縮可能な布状材からなり、対向する第1部材の円筒曲面部と第2部材の円筒曲面部との間の空間の上方を塞ぐように、第1部材及び第2部材の上部に接続された上部連結部材と、を有し、 第1部材と第2部材とは、双方の前記円筒曲面部の周方向の端部及び双方の円筒曲面部の下部が、第1部材と第2部材との間に充填された填充材の漏出が生じないように、互いに連結又は連結用の布状材を介して連結されている填充材収容体を提供する。

In order to solve the above problem, the invention according to claim 1 is between a track slab arranged on a roadbed concrete and a railroad rail being fastened to an upper surface, and a cylindrical protrusion raised from the roadbed concrete. It is a filling material accommodating body for filling the arc-shaped gap of the above, and is made of a thin plate material having a large number of small holes from which the filling material oozes, and a cylindrical curved surface portion along the peripheral surface of the protrusion is formed. It is composed of a first member that is self-supporting while maintaining the shape of the cylindrical curved surface portion, and a thin plate material having a large number of small holes that the filling material exudes, so as to face the peripheral surface of the protrusion at a distance. A first member, which includes a cylindrical curved surface portion along a concave cylindrical curved surface of the formed orbital slab and is self-supporting while maintaining the shape of the cylindrical curved surface portion, and a stretchable cloth-like material, which face each other. The first member has an upper connecting member connected to the upper part of the first member and the second member so as to close the upper part of the space between the cylindrical curved portion of the member and the cylindrical curved portion of the second member. And the second member, the peripheral end portion of both the cylindrical curved surface portions and the lower portion of both cylindrical curved surface portions do not leak the filling material filled between the first member and the second member. As described above, a filler container which is connected to each other or is connected to each other via a cloth-like material for connecting is provided.

この填充材収容体では、第1部材及び第2部材が有する円筒曲面部が自立するので、突起と軌道スラブとの間隙に容易に差し入れて、それぞれの円筒曲面部を円柱状の突起の外周面及び軌道スラブの凹状の円筒曲面に対向させることができる。そして、それぞれの円筒曲面部は、突起の外周面及び軌道スラブの凹状の円筒曲面に沿った形状に成形されていることにより、填充材を充填したときにしわが生じることなく、円筒曲面部が突起の外周面及び軌道スラブの凹状の円筒曲面に当接され、にじみ出した填充材が密着する。
また、第1部材と第2部材との上部は伸縮が可能な上部連結部材によって連結されており、軌道スラブと突起との間隔が一定でないときにも、第1部材と第2の部材とを相対的に変位させ、双方の円筒曲面部をしわ等が生じていない状態で突起の外周面及び軌道スラブの凹状の円筒曲面に当接させることができる。
In this filler accommodating body, since the cylindrical curved surface portion of the first member and the second member is self-supporting, it can be easily inserted into the gap between the protrusion and the track slab, and each cylindrical curved surface portion is inserted into the outer peripheral surface of the cylindrical protrusion. And can face the concave cylindrical curved surface of the orbital slab. Since each of the cylindrical curved surfaces is formed into a shape along the outer peripheral surface of the protrusion and the concave cylindrical curved surface of the orbital slab, the cylindrical curved surface portion is projected without wrinkles when the filler is filled. The filler material that has exuded from the outer peripheral surface of the slab and the concave cylindrical curved surface of the orbital slab is in close contact with the curved surface.
Further, the upper portion of the first member and the second member is connected by an upper / contractable upper connecting member, and even when the distance between the track slab and the protrusion is not constant, the first member and the second member can be connected. By relatively displacement, both cylindrical curved surfaces can be brought into contact with the outer peripheral surface of the protrusion and the concave cylindrical curved surface of the orbital slab without wrinkles or the like.

請求項2に係る発明は、請求項1に記載の填充材収容体において、 第1部材は、該第1部材の円筒曲面部の上縁から第2部材に向かってほぼ水平に張り出した第1フランジ部を有し、 第2部材は、該第2部材の円筒曲面部の上縁から第1部材に向かってほぼ水平に張り出した第2フランジ部を有するものとする。 The invention according to claim 2 is the first member of the filler housing according to claim 1, wherein the first member projects substantially horizontally from the upper edge of the cylindrical curved surface portion of the first member toward the second member. It has a flange portion, and the second member has a second flange portion that projects substantially horizontally from the upper edge of the cylindrical curved surface portion of the second member toward the first member.

この填充材収容体では、第1部材と第2部材との間に充填された填充材が円筒曲面部の上部まで達したときに、第1フランジ部及び第2フランジ部の円筒曲面部から張り出した形状に倣って填充材の上面が平坦に成形される。したがって、充填された填充材の上部を平坦に仕上げることが容易となる。 In this filler accommodating body, when the filler filled between the first member and the second member reaches the upper part of the cylindrical curved surface portion, it projects from the cylindrical curved surface portion of the first flange portion and the second flange portion. The upper surface of the filler is formed flat according to the shape of the filler. Therefore, it becomes easy to finish the upper part of the filled filler flat.

請求項3に係る発明は、請求項1又は請求項2に記載の填充材収容体において、 第1部材及び第2部材を構成する薄板材は、熱可塑性樹脂を主材料とする多数の繊維が互いに交叉するように平坦な面又は曲面に沿って配され、交叉する繊維が加熱及び加圧によって接合され、繊維間に前記填充材がにじみ出す小孔が形成されているものとする。 In the invention according to claim 3, in the filling material accommodating body according to claim 1 or 2, the thin plate material constituting the first member and the second member is composed of a large number of fibers mainly made of a thermoplastic resin. It is assumed that the fibers are arranged along a flat surface or curved surface so as to intersect each other, and the intersecting fibers are joined by heating and pressurizing, and small holes where the filler oozes out are formed between the fibers.

この填充材収容体では、熱可塑性樹脂の繊維を含む織布又は不織布を加熱及び加圧することによって容易に成形することができるとともに円筒曲面部を自立可能な剛性を有するものとすることができる。また、繊維の密度、繊維の太さ及び加圧時の圧力の調整等によって繊維間に填充材がにじみ出す小孔を形成することができる。
なお、繊維はすべてが熱可塑性樹脂からなるものに限定されず、熱可塑性樹脂以外の材料からなる繊維や熱可塑性樹脂で溶融温度が異なるものからなる繊維を混合して使用されたものであってもよい。

請求項4に係る発明は、請求項1から請求項3までのいずれかに記載の填充材収容体において、 前記上部連結部材の上面には、第1部材と第2部材との間のほぼ中央部に、第1部材及び第2部材が有する円筒曲面部の周方向に沿った帯状の上面板が貼り付けられているものとする。 The invention according to claim 4 is the filling material accommodating body according to any one of claims 1 to 3, wherein the upper surface of the upper connecting member is substantially in the center between the first member and the second member. It is assumed that a strip-shaped top plate along the circumferential direction of the cylindrical curved surface portion of the first member and the second member is attached to the portion.

この填充材収容体では、突起の外周面と軌道スラブの凹状の円筒曲面との間隔が広くなっているときに、填充材の上面の形状が上面板によって規制され、充填された填充材の表面を平らに仕上げることが容易となる。 In this filler housing, when the distance between the outer peripheral surface of the protrusion and the concave cylindrical curved surface of the track slab is wide, the shape of the upper surface of the filler is regulated by the top plate, and the surface of the filler is filled. It becomes easy to finish flat.

請求項5に係る発明は、請求項1から請求項4までのいずれかに記載の填充材収容体において、 第2部材の円筒曲面部の周方向の両端縁から該円筒曲面部の外側へ張り出した周端ガイド部を有するものとする。 The invention according to claim 5 is the filling material accommodating body according to any one of claims 1 to 4, wherein the cylindrical curved surface portion of the second member projects from both end edges in the circumferential direction to the outside of the cylindrical curved surface portion. It shall have a peripheral end guide portion.

この填充材収容体では、軌道スラブの凹状の円筒曲面が形成されている端面に周端ガイド部を沿わせて上方から突起と軌道スラブとの間に差し入れることにより、軌道スラブの凹状の円筒曲面と突起の外周面との間に正確に装着することが可能となる。 In this filler housing, the concave cylinder of the track slab is formed by inserting the peripheral end guide portion along the end surface on which the concave cylindrical curved surface of the track slab is formed and inserting it between the protrusion and the track slab from above. It can be accurately mounted between the curved surface and the outer peripheral surface of the protrusion.

請求項6に係る発明は、請求項1から請求項5までのいずれかに記載の填充材収容体において、 第1部材の円筒曲面部の下端に連続し、第2部材と対向する方向に拡径された円筒曲面を形成する下端拡径部と、 第2部材の円筒曲面部の下端に連続し、第1部材と対向する方向に縮径された円筒曲面を形成する下端縮径部と、を有し、 前記下端拡径部と前記下端縮径部とが重ね合わされ、接合されているものとする。 The invention according to claim 6 is the filler accommodating body according to any one of claims 1 to 5, which is continuous with the lower end of the cylindrical curved surface portion of the first member and extends in a direction facing the second member.

この填充材収容体では、第1部材の円筒曲面部と連続するように形成された下端拡径部と第2部材の円筒曲面部と連続するように形成された下端縮径部とを重ね合わせて接合することにより、第1部材と第2部材の下部を、填充材が漏出しないように接合することが容易となる。また、重ね合わされた下端拡径部と下端縮径部とによって路盤コンクリート上で第1部材と第2部材との円筒曲面部を所定の高さに支持することができる。したがって、軌道スラブがセメントアスファルトモルタル等の層を介して路盤コンクリート上に支持されているときに、軌道スラブの凹状の円筒曲面に第2部材の円筒曲面部を当接させることができる。つまり、填充材を充填する高さの範囲を限定するために、収容体の下部に支持部材を設ける必要がなくなる。 In this filler accommodating body, the lower end diameter enlarged portion formed so as to be continuous with the cylindrical curved surface portion of the first member and the lower end diameter reduced portion formed so as to be continuous with the cylindrical curved surface portion of the second member are overlapped. By joining the members, it becomes easy to join the first member and the lower part of the second member so that the filling material does not leak. Further, the cylindrical curved surface portion of the first member and the second member can be supported at a predetermined height on the roadbed concrete by the overlapped lower end diameter expanding portion and the lower end diameter reducing portion. Therefore, when the track slab is supported on the roadbed concrete via a layer such as cement asphalt mortar, the cylindrical curved surface portion of the second member can be brought into contact with the concave cylindrical curved surface of the track slab. That is, in order to limit the range of heights for filling the filler, it is not necessary to provide a support member at the lower part of the housing.

An injection port 15 for filling a filling material is provided between the first member 11 and the second member 12 at the peripheral ends of the portions 11a and 12a.

上記第1部材11は、填充材がにじみ出す程度の大きさの小孔を多数有する薄板材からなり、図3に示すように突起6の外周面とほぼ同形状の円筒曲面部11aと、この円筒曲面部11aの上縁から対向する第2部材側にほぼ水平に張りだした第1フランジ部11bと、上記円筒曲面部11aの下側に連続して設けられ、該円筒曲面部11aより曲率半径が拡大された下端拡径部11cと、円筒曲面部11aの周方向の端縁から対向する第2部材側に張り出してほぼ鉛直な面を形成する周端張出部11dとを有するものである。 The first member 11 is made of a thin plate material having a large number of small holes having a size such that the filling material oozes out, and as shown in FIG. 3, a cylindrical curved surface portion 11a having substantially the same shape as the outer peripheral surface of the protrusion 6 and the cylindrical curved surface portion 11a thereof. The first flange portion 11b projecting substantially horizontally from the upper edge of the cylindrical curved surface portion 11a to the side of the second member facing the cylindrical curved surface portion 11a and the lower side of the cylindrical curved surface portion 11a are continuously provided and curved from the cylindrical curved surface portion 11a. It has a lower end enlarged diameter portion 11c with an enlarged radius and a peripheral end protruding portion 11d that projects from the peripheral edge of the cylindrical curved surface portion 11a toward the opposite second member side to form a substantially vertical surface. is there.

この第1部材11を構成する薄板材は、熱可塑性樹脂からなる繊維を含む不織布を加熱し、金型内で加圧したものである。これにより、多数の熱可塑性樹脂の繊維が互いに交叉する部分で溶融又は軟化し、圧着されることによって剛性を有する薄い板状となる。そして、金型によって上記円筒曲面部11a、第1フランジ部11b、下端拡径部11c及び周端張出部11dが連続した一体の部材として形成されたものである。この薄板状となった第1部材11は、交叉する繊維が互いに結合されることによって剛性を有するものとなる。そして、その剛性は、円筒曲面部11aが軸線を上下方向にして自立する程度のものであって、第1フランジ部11bはほぼ水平に張り出した状態を維持することができる剛性を有するものとする。また、金型内で熱可塑性樹脂が加熱及び加圧されても繊維間の空隙が残り、填充材がにじみ出すことができる程度の小孔が存在する程度に加熱及び加圧されたものである。

The thin plate material constituting the first member 11 is obtained by heating a non-woven fabric containing fibers made of a thermoplastic resin and pressurizing it in a mold. As a result, a large number of thermoplastic resin fibers are melted or softened at the intersections with each other, and are pressure-bonded to form a thin plate having rigidity. Then, the cylindrical curved surface portion 11a, the first flange portion 11b, the lower end diameter expanding portion 11c, and the peripheral end overhanging portion 11d are formed as a continuous integrated member by the mold. The thin plate-shaped first member 11 has rigidity due to the intersecting fibers being bonded to each other. The rigidity is such that the cylindrical curved surface portion 11a stands on its own with its axis oriented in the vertical direction, and the first flange portion 11b has rigidity capable of maintaining a state in which it projects substantially horizontally. .. Further, even if the thermoplastic resin is heated and pressurized in the mold, the gaps between the fibers remain and the filler is heated and pressurized to the extent that there are small holes to the extent that the filler can ooze out. ..
In the above-mentioned non-woven fabric, all the fibers may be made of a thermoplastic resin, but the non-woven fabric may contain fibers made of a material other than the thermoplastic resin, and the thermoplastic resin is also a resin having a different melting temperature. The fibers using the above may be mixed. Further, the thickness of the fiber, the density of the fiber, and the like can be adjusted together with the material of the fiber so as to satisfy the conditions of the rigidity of the thin plate material and the presence of small holes.

上記第2部材12は、軌道スラブ3に形成された切欠部内の円筒曲面とほぼ同形状の円筒曲面部12aと、この円筒曲面部12aの上縁から対向する第1部材側に張り出した第2フランジ部12bと、上記円筒曲面部12aの下側に連続して設けられ、該円筒曲面部12aより曲率半径が縮小された下端縮径部12cと、円筒曲面部12aの周方向の端縁から対向する第1部材11と反対側、つまり円筒曲面の外側に張り出してほぼ鉛直な面を形成する周端ガイド部12dとを有するものである。
この第2部材12は、第1部材11と同じ薄板材からなるものであり、同様に金型内で円筒曲面部12a、第2フランジ部12b、下端縮径部12c及び周端ガイド部12dが一体に連続するものとして形成されたものである。そして、同様に円筒曲面部12aが自立し、第2フランジ部が張り出した状態を維持することができる程度の剛性を有するとともに、填充材がにじみ出す多数の小孔を有するものである。
The second member 12 has a cylindrical curved surface portion 12a having substantially the same shape as the cylindrical curved surface portion in the notch formed in the track slab 3, and a second member protruding from the upper edge of the cylindrical curved surface portion 12a toward the first member side.

It has a peripheral end guide portion 12d that projects to the outside of the cylindrical curved surface and forms a substantially vertical surface on the side opposite to the first member 11 that faces the opposite side.
The second member 12 is made of the same thin plate material as the first member 11, and similarly, the cylindrical curved surface portion 12a, the second flange portion 12b, the lower end diameter reduction portion 12c, and the peripheral end guide portion 12d are formed in the mold. It was formed as one continuous object. Similarly, the cylindrical curved surface portion 12a is self-supporting, has a rigidity sufficient to maintain the state in which the second flange portion is overhanging, and has a large number of small holes from which the filling material oozes out.

第1部材11の下端拡径部11cと第2部材12の下端縮径部12cとは、円筒曲面を形成しており、その径は第1部材11の下端拡径部11cが第2部材12の下端縮径部12cよりわずかに小さくなっている。そして、第1部材11と第2部材12とは、下端拡径部11cと下端縮径部12cとを重ね合わせ、加熱及び加圧することによって接合されている。これにより第1部材の円筒曲面部11aと第2部材の円筒曲面部12aとが間隔をあけて互いに対向するとともに、第1部材と第2部材との下部から填充材が漏出しないように封鎖するものである。 The lower end diameter enlarged portion 11c of the first member 11 and the lower end diameter reduced portion 12c of the second member 12 form a cylindrical curved surface, and the diameter of the lower end diameter enlarged portion 11c of the first member 11 is the second member 12 It is slightly smaller than the lower end reduced diameter portion 12c of. The first member 11 and the second member 12 are joined by superimposing the lower end diameter expanding portion 11c and the lower end diameter reducing portion 12c, heating and pressurizing. As a result, the cylindrical curved surface portion 11a of the first member and the cylindrical curved surface portion 12a of the second member face each other with a gap, and the filling material is sealed so as not to leak from the lower part of the first member and the second member. It is a thing.

上記上部連結部材13は、伸縮可能な布状材からなり、第1部材11及び第2部材12の湾曲した平面形状に沿って平面形状が湾曲した帯状の部材である。そして、両側縁がそれぞれ第1部材11及び第2部材12の上部で第1フランジ部11b及び第2フランジ部12bの下側の円筒曲面部11a,12aに接合されている。これにより、図4に示すように対向する第1部材の円筒曲面部11aと第2部材の円筒曲面部12aとの間の空間の上方を塞ぐように、第1部材11及び第2部材12の上部を連結するものである。これにより、填充材が充填される前では、図4に示すように上部連結部材13がやや垂れ下がった状態となる。
上部連結部材13と第1部材11及び第2部材12との接合は、加熱及び加圧によって接着する、いわゆるヒートシールとするのが望ましいが、その他の方法、例えば縫合等であっても良い。
The upper connecting member 13 is made of a stretchable cloth-like material, and is a strip-shaped member whose planar shape is curved along the curved planar shape of the first member 11 and the second member 12. Both side edges are joined to the lower cylindrical curved surface portions 11a and 12a of the first flange portion 11b and the second flange portion 12b at the upper portions of the first member 11 and the second member 12, respectively. As a result, as shown in FIG. 4, the first member 11 and the second member 12 are closed so as to close the upper part of the space between the cylindrical curved surface portion 11a of the first member and the cylindrical curved surface portion 12a of the second member. It connects the upper parts. As a result, before the filling material is filled, the upper connecting member 13 is in a slightly hanging state as shown in FIG.
The upper connecting member 13 and the first member 11 and the second member 12 are preferably bonded by heating and pressurizing, that is, a so-called heat seal, but other methods such as suturing may be used.

上部連結部材13の上面には、湾曲した形状の中心線に沿って所定幅の上面板16が張り付けられている。この上面板16は、第1部材11又は第2部材12とほぼ同等の剛性を有する薄板材を用いるのが望ましいが、填充材がにじみ出す小孔は設けられていてもよいし、設けられていないものであってもよい。この上面板16は、突起6の外周面と軌道スラブ3の切欠部内の円筒曲面との間隙の中心線に沿って湾曲した形状で、その幅は、突起6の外周面と軌道スラブ3の切欠部内の円筒曲面との間隔の許容最小幅よりわずかに小さい寸法とするのが望ましい。また、この上面板16と上部連結部材13との接着は、上面板13の全幅ではなく、中心線に沿って双方の接合が可能な小さい幅で接着するのが望ましい。これにより上部連結部材13の伸縮が制限されるのを抑制するものとなっている。
なお、上記許容最小幅は、突起6の外周面と軌道スラブ3の切欠部内の円筒曲面との間隔の設計値に対して施工誤差等による増減が許容される範囲として定められた最小値である。また、許容される範囲の最大値は許容最大幅として予め定められる。
A top plate 16 having a predetermined width is attached to the upper surface of the upper connecting member 13 along a center line having a curved shape. For the top plate 16, it is desirable to use a thin plate material having substantially the same rigidity as the first member 11 or the second member 12, but small holes where the filling material oozes out may be provided or provided. It may not be. The upper surface plate 16 has a shape curved along the center line of the gap between the outer peripheral surface of the protrusion 6 and the cylindrical curved surface in the notch of the orbital slab 3, and the width thereof is the outer peripheral surface of the protrusion 6 and the notch of the orbital slab 3. It is desirable that the dimension is slightly smaller than the minimum allowable width of the distance from the cylindrical curved surface in the part. Further, it is desirable that the upper surface plate 16 and the upper connecting member 13 are adhered not by the entire width of the upper surface plate 13 but by a small width that allows both to be joined along the center line. As a result, the expansion and contraction of the upper connecting member 13 is suppressed.
The allowable minimum width is a minimum value defined as a range in which an increase or decrease due to a construction error or the like is permitted with respect to the design value of the distance between the outer peripheral surface of the protrusion 6 and the cylindrical curved surface in the notch of the track slab 3. .. Further, the maximum value in the allowable range is predetermined as the maximum allowable width.

上記側端連結部材14は、布状の部材であって、図2に示すように上下方向の軸線を有する帯状の部材である。そして、両側縁が第1部材11及び第2部材12の周方向の端部を互いに連結し、第1部材11と第2部材11との間の空間を封鎖するものである。
側端連結部材14と第1部材11及び側端連結部材14と第2部材12との接合は、図5に示すように、第1部材の周端張出部11dと第2部材の周端ガイド部12dにそれぞれ側端連結部材14の両縁部を接着するものである。接着は加熱及び加圧によるヒートシールとするのが望ましい。
The side end connecting member 14 is a cloth-shaped member, and is a strip-shaped member having an axis in the vertical direction as shown in FIG. Then, both side edges connect the peripheral ends of the first member 11 and the second member 12 to each other, and block the space between the first member 11 and the second member 11.
As shown in FIG. 5, the joint between the side end connecting member 14 and the first member 11 and the side end connecting member 14 and the second member 12 is formed between the peripheral end overhanging portion 11d of the first member and the peripheral end of the second member. Both edges of the side end connecting members 14 are adhered to the guide portions 12d, respectively. Adhesion is preferably heat-sealed by heating and pressurizing.

第1部材及び第2部材の円筒曲面部11a,12aを周方向の両端で連結する側端連結部材14の少なくともいずれか一方は、図2に示すように第1部材11及び第2部材12の上端より上方に延長されている。一方、上部連結部材13は、側端連結部材14が上方に延長された周方向の端部で、円筒曲面部11a,12aの周方向の端部より延長されている。そして、側端連結部材14の上方に延長された延長部分14aと、上部連結部材13の延長部分13aとは、帯状となった両側縁部が接合され、筒状となった部分を形成している。この筒状となった部分の内側は、図6に示すように第1フランジ部11b及び第2フランジ部12bの下側で第1部材と第2部材の円筒曲面部11a,12aの間の空間に連通し、第1部材11と第2部材12との間へ填充材を充填するための注入口15となっている。 As shown in FIG. 2, at least one of the side end connecting members 14 that connect the cylindrical curved surface portions 11a and 12a of the first member and the second member at both ends in the circumferential direction is the first member 11 and the second member 12. It extends above the top edge. On the other hand, the upper connecting member 13 is an end portion in the circumferential direction in which the side end connecting member 14 is extended upward, and is extended from the end portion in the circumferential direction of the cylindrical curved surface portions 11a and 12a. Then, the extension portion 14a extended above the side end connecting member 14 and the extension portion 13a of the upper connecting member 13 are joined to form a tubular portion by joining both side edge portions in a band shape. There is. As shown in FIG. 6, the inside of the tubular portion is a space between the cylindrical curved surfaces 11a and 12a of the first member and the second member under the first flange portion 11b and the second flange portion 12b. Is an injection port 15 for filling the filling material between the first member 11 and the second member 12.

以上に説明したように構成された填充材収容体10は、図7に示すように路盤コンクリート1から立ち上げられた突起6と軌道スラブ3の切欠部との間の円弧状の間隙8に上方から差し入れることができる。このとき周端ガイド部12dが軌道スラブの端面3bに当接するように位置を合わせ、軌道スラブの端面3bに沿って下降させることにより、突起6の外周面6aと軌道スラブ3の切欠部内の円筒曲面3cとが対向する領域に正確に装着することができる。そして、図4に示すように重ね合わされた下端拡径部11cと下端縮径部12cとによって路盤コンクリート1上に支持され、第2部材の円筒曲面部12aがセメントアスファルトモルタル層2の上に支持された軌道スラブ3の円筒曲面3cに対向する位置に装着される。 As shown in FIG. 7, the filler accommodating body 10 configured as described above is above the arcuate gap 8 between the protrusion 6 raised from the roadbed concrete 1 and the notch portion of the track slab 3. You can insert it from. At this time, the peripheral end guide portion 12d is aligned so as to abut on the end surface 3b of the track slab, and is lowered along the end surface 3b of the track slab so that the outer peripheral surface 6a of the protrusion 6 and the cylinder in the notch portion of the track slab 3 are formed. It can be accurately mounted in the region facing the curved surface 3c. Then, as shown in FIG. 4, the lower end enlarged diameter portion 11c and the lower end reduced diameter portion 12c are supported on the roadbed concrete 1, and the cylindrical curved surface portion 12a of the second member is supported on the cement asphalt mortar layer 2. It is mounted at a position facing the cylindrical curved surface 3c of the track slab 3.

上述のように填充材収容体10が突起6と軌道スラブ3との間に装着された状態で、図4に示すように第1部材11と第2部材12との間に注入口15から流動性を有する填充材が充填される。このとき、第1部材の円筒曲面部11aは、突起6の外周面6aとほぼ同形状に成形されており、第1部材の円筒曲面部11aは突起6の外周面6aに大きな隙間を生じることなく当接される。また、第2部材の円筒曲面部12aも同様に軌道スラブ3の切欠部内の円筒曲面3cに沿って大きな隙間を生じることなく当接される。そして、第1部材11と第2部材12との間に円筒曲面部11a,12aの上端まで充填される。このとき、図4に示すように第1部材11と第2部材12の間に貯留された填充材7の流体圧Pによって第1部材及び第2部材の円筒曲面部11a,12aが突起6の外周面及び軌道スラブ3の円筒曲面に押し付けられ、下端縮径部11c及び下端拡径部12cに填充材の重量による負荷が大きく作用することなく、填充材収容体10の位置が維持される。 As described above, with the filler accommodating body 10 mounted between the protrusion 6 and the track slab 3, flow from the injection port 15 between the first member 11 and the second member 12 as shown in FIG. Filling material with properties is filled. At this time, the cylindrical curved surface portion 11a of the first member is formed to have substantially the same shape as the outer peripheral surface 6a of the protrusion 6, and the cylindrical curved surface portion 11a of the first member creates a large gap in the outer peripheral surface 6a of the protrusion 6. Will be contacted without. Further, the cylindrical curved surface portion 12a of the second member is also brought into contact with the cylindrical curved surface portion 12a of the track slab 3 along the cylindrical curved surface 3c in the notch portion without forming a large gap. Then, the space between the first member 11 and the second member 12 is filled up to the upper ends of the cylindrical curved surface portions 11a and 12a. At this time, as shown in FIG. 4, the cylindrical curved surfaces 11a and 12a of the first member and the second member are formed by the protrusions 6 due to the fluid pressure P of the filling material 7 stored between the first member 11 and the second member 12. The position of the filling material accommodating body 10 is maintained without being pressed against the outer peripheral surface and the cylindrical curved surface of the orbital slab 3 and exerting a large load on the lower end diameter reducing portion 11c and the lower end diameter expanding portion 12c due to the weight of the filling material.

填充材が円筒曲面部11a,12aの上部まで充填されると、図4に示すようにやや垂れ下がるように支持されていた上部連結部材13及び上面板16は、填充材7の上面によって押し上げられ、図8に示すように第1フランジ部11b及び第2フランジ部12bの下面に押し付けられる。そして、第1フランジ部11b及び第2フランジ部12bはほぼ水平に張り出した状態を維持することができる程度の剛性を有することによって填充材7の上面を押さえ、填充材の上面を平坦にすることができる。また、上面板16は第1フランジ部11bと第2フランジ部12bとの間に下側から架け渡すように押し付けられ、充填された填充材7の表面を平端にすることに寄与するものとなる。これにより第1部材11と第2部材12との間に充填されて第1部材及び第2部材の円筒曲面部11a,12aからにじみ出した填充材7は突起6及び軌道スラブ3に密着し、填充材収容体10にしわが生じたり、よじれたりすることなく填充材7を良好な状態で充填することが可能となる。このような状態で填充材が硬化することにより、軌道スラブ3は突起6によって位置が規制されるものとなる。 When the filling material is filled to the upper part of the cylindrical curved surface portions 11a and 12a, the upper connecting member 13 and the upper surface plate 16 which are supported so as to hang down slightly as shown in FIG. 4 are pushed up by the upper surface of the filling material 7. As shown in FIG. 8, it is pressed against the lower surfaces of the first flange portion 11b and the second flange portion 12b. Then, the first flange portion 11b and the second flange portion 12b hold the upper surface of the filler 7 by having a rigidity sufficient to maintain a state of being projected substantially horizontally, and flatten the upper surface of the filler. Can be done. Further, the upper surface plate 16 is pressed so as to bridge between the first flange portion 11b and the second flange portion 12b from the lower side, and contributes to flattening the surface of the filled filler 7. .. As a result, the filling material 7 that is filled between the first member 11 and the second member 12 and exudes from the cylindrical curved surface portions 11a and 12a of the first member and the second member adheres to the protrusion 6 and the track slab 3 and is filled. It is possible to fill the filling material 7 in a good state without causing wrinkles or kinks in the material accommodating body 10. When the filler is cured in such a state, the position of the track slab 3 is regulated by the protrusion 6.

また、突起6の外周面と軌道スラブ3の切欠部内の円筒曲面との間隔が、施工時の誤差等によってあらかじめ定められた設計値より大きく又は小さくなっているときにも、第1部材と第2部材の円筒曲面部11a,12aは、それぞれ突起3の外周面及び軌道スラブ3の円筒曲面に沿って正確に当接される。つまり、突起6の外周面と軌道スラブ3の円筒曲面が鋼型枠を用いて正確な形状に形成されており、この形状に沿ってほぼ同じ形状に第1部材と第2部材の円筒曲面部11a,12aが成形されている。そして、伸縮可能な上部連結部材13で連結された第1部材11と第2部材12とが相対的に移動し、それぞれが突起6の外周面と軌道スラブ3の円筒曲面に正確に当接される。したがって、突起6と軌道スラブ3との間隔が異なるときにも、填充材収容体10にしわやよじれを生じることなく良好な状態で填充材が充填される。 Further, even when the distance between the outer peripheral surface of the protrusion 6 and the cylindrical curved surface in the notch of the track slab 3 is larger or smaller than a predetermined design value due to an error during construction or the like, the first member and the first member The cylindrical curved surfaces 11a and 12a of the two members are accurately abutted along the outer peripheral surface of the protrusion 3 and the cylindrical curved surface of the orbital slab 3, respectively. That is, the outer peripheral surface of the protrusion 6 and the cylindrical curved surface of the track slab 3 are formed into an accurate shape by using a steel formwork, and the cylindrical curved surface portions of the first member and the second member have substantially the same shape along this shape. 11a and 12a are molded. Then, the first member 11 and the second member 12 connected by the expandable upper connecting member 13 move relatively, and each of them is accurately contacted with the outer peripheral surface of the protrusion 6 and the cylindrical curved surface of the track slab 3. To.
