PROBLEM TO BE SOLVED: To provide a railway sleeper direct-coupled track structure with a concrete track bed as thin as possible in thickness having a high salt damage resistance capable of being easily constructed in a shorter construction period.SOLUTION: The railway sleeper direct-coupled track structure supports railway sleepers on a concrete track bed. The concrete track bed is formed within a length of the railway sleeper in a longitudinal direction, and is not constructed on the shoulders of the railway sleeper.

Description

本発明は、コンクリート製のまくらぎをコンクリート道床に敷設するまくらぎ直結軌道構造に関する。   The present invention relates to a sleeper direct connection track structure in which a concrete sleeper is laid on a concrete roadbed.

従来より、鉄道軌道のまくらぎ直結軌道構造として、特許文献１や図７に示すように、まくらぎ１１０を路盤に敷設されたコンクリート道床１２０で支持する構造が知られている。コンクリート道床１２０は、内部に鉄筋やセパレータを備えており、該鉄筋によって鉄筋コンクリート構造としてまくらぎ１１０から伝わる荷重を負荷している。   Conventionally, as a sleeper direct connection track structure of a railway track, as shown in Patent Document 1 and FIG. 7, a structure in which a sleeper 110 is supported by a concrete road bed 120 laid on a roadbed is known. The concrete road bed 120 includes a reinforcing bar and a separator inside, and a load transmitted from the sleeper 110 as a reinforced concrete structure is applied by the reinforcing bar.

また、このような鉄道軌道のまくらぎ直結軌道構造は、防振等を目的としてまくらぎ１１０とコンクリート道床１２０の間にゴム製のまくらぎパット１１３を介在させている。   In addition, such a railway track sleeper direct track structure has a rubber sleeper pad 113 interposed between the sleeper 110 and the concrete roadbed 120 for the purpose of vibration isolation or the like.

このような構造によれば、コンクリート道床１２０の剛性が向上することで、まくらぎ直結軌道構造の長期的安定化を図ることができるという効果を奏する。   According to such a structure, there is an effect that the rigidity of the concrete road bed 120 is improved, so that the long-term stabilization of the direct sleeper track structure can be achieved.

このようなまくらぎ直結軌道構造の施工方法は、路盤１００に鉄筋，セパレータ及びまくらぎ１１０の肩部を覆うように外郭を画成する型枠を施工して該型枠内にコンクリートの打込みを行いコンクリート道床１２０を施工する。なお、まくらぎ１１０の肩部とは、まくらぎ１１０の長手方向に沿った両端面と定義される。   The construction method of such a sleeper direct track structure is to construct a formwork that defines the outer shell on the roadbed 100 so as to cover the shoulders of the reinforcing bars, separators and sleepers 110, and then put concrete into the formwork. The concrete roadbed 120 is constructed. The shoulder portion of the sleeper 110 is defined as both end faces along the longitudinal direction of the sleeper 110.

また、他のまくらぎ直結軌道構造としては、特許文献２に示すように、まくらぎに左右方向の変位を拘束するための突起を設け、軌道桁に形成した嵌合溝に該突起を嵌合させて支持する構造が知られている。   As another structure for directly connecting a sleeper, as shown in Patent Document 2, a protrusion for restraining displacement in the left-right direction is provided on the sleeper, and the protrusion is fitted into a fitting groove formed in the track girder. There are known structures that support them.

このような構造によれば、容易にまくらぎの位置決めを行うことができ、良好な防振効果を得ることができる。   According to such a structure, the sleeper can be positioned easily and a good vibration isolation effect can be obtained.

しかし、上述した特許文献１に記載されたまくらぎ直結軌道構造は、鉄筋の加工や配筋が複雑で煩雑となり、まくらぎの肩部を覆うような型枠の形状が複雑で容易に施工することができないという問題があった。また、鉄筋のかぶり確保のために、コンクリート道床１２０の厚みを薄くすることが難しいと共に、まくらぎパット１１３の形状が複雑となることで施工期間が長くなり、施工コストの抑制を図ることが難しいという問題があった。さらに、コンクリート道床１２０に鉄筋を使用しているので、沿岸部などに施工した場合、耐塩害性が低いという問題もあった。   However, the sleeper direct-coupled track structure described in Patent Document 1 described above is complicated and complicated in rebar processing and bar arrangement, and the shape of the formwork covering the shoulder of the sleeper is complicated and easy to construct. There was a problem that could not. In addition, it is difficult to reduce the thickness of the concrete roadbed 120 in order to secure the cover of the reinforcing bars, and the construction period becomes longer due to the complicated shape of the sleeper pad 113, and it is difficult to suppress the construction cost. There was a problem. Furthermore, since the reinforcing bars are used for the concrete roadbed 120, there is a problem that the salt damage resistance is low when the concrete roadbed 120 is constructed in a coastal area.

そこで、本発明は上記問題に鑑みてなされたものであり、施工期間が短くなると共に容易に施工することができ、コンクリート道床の厚さを極力薄く設定することができると共に、コンクリート道床の耐塩害性も高いまくらぎ直結軌道構造を提供することを目的とする。   Therefore, the present invention has been made in view of the above problems, and the construction period is shortened and can be easily constructed, and the thickness of the concrete roadbed can be set as thin as possible, and the salt damage damage of the concrete roadbed can be achieved. The purpose is to provide a sleeper direct track structure with high performance.

本発明に係るまくらぎ直結軌道構造は、コンクリート道床でまくらぎを支持するまくらぎ直結軌道構造において、前記コンクリート道床は、前記まくらぎの長手方向の長さ内に形成されると共に、前記まくらぎの肩部には施工されないことを特徴とする。   The sleeper direct connection track structure according to the present invention is a sleeper direct connection track structure in which a sleeper is supported by a concrete roadbed, wherein the concrete roadbed is formed within a longitudinal length of the sleeper and the shoulder of the sleeper. It is characterized by not being constructed in the part.

また、本発明に係るまくらぎ直結軌道構造において、前記まくらぎの側面及び底面には弾性材が貼り付けられていることが好ましい。   Moreover, in the sleeper direct connection track structure according to the present invention, it is preferable that an elastic material is attached to a side surface and a bottom surface of the sleeper.

また、本発明に係るまくらぎ直結軌道構造において、前記弾性材は、少なくとも一方の側面からまくらぎ底部側へ突出していることが好ましい。   Moreover, in the sleeper direct connection track structure according to the present invention, it is preferable that the elastic material protrudes from at least one side surface toward the sleeper bottom.

また、本発明に係るまくらぎ直結軌道構造において、前記まくらぎの側面には、少なくとも一組の凸部が形成されていることが好ましい。   In the direct sleeper track structure according to the present invention, it is preferable that at least one set of convex portions is formed on a side surface of the sleeper.

また、本発明に係るまくらぎ直結軌道構造において、前記凸部は、幅寸法が前記まくらぎの長手方向に沿って徐々に拡幅する拡幅部と、前記拡幅部の端部から長手方向に沿って幅寸法が徐々に縮幅する縮幅部を備えることが好ましい。   Moreover, in the sleeper direct connection track structure according to the present invention, the convex portion has a widened portion whose width dimension gradually widens along the longitudinal direction of the sleeper, and a width along the longitudinal direction from the end of the widened portion. It is preferable to provide a reduced width portion whose dimensions are gradually reduced.

また、本発明に係るまくらぎ直結軌道構造において、前記コンクリート道床は、無筋の短繊維補強コンクリートを使用した道床であることが好ましい。   In the direct sleeper track structure according to the present invention, the concrete roadbed is preferably a roadbed using unreinforced short fiber reinforced concrete.

本発明に係るまくらぎ直結軌道構造は、まくらぎが拡幅部と縮幅部を備えているので、該拡幅部及び縮幅部によってコンクリート道床に拘束されるので枠体をまくらぎの長手方向端部に当接するようにまくらぎ直結軌道構造の長手方向に沿って配設することでコンクリート道床及び枠体の構造を単純化することができ、施工期間が短くできると共に、容易に施工することができる。   In the sleeper direct connection track structure according to the present invention, the sleeper is provided with a widened portion and a reduced width portion, so that the frame body is constrained to the concrete roadbed by the widened portion and the reduced width portion, so that the frame body ends in the longitudinal direction of the sleeper. The structure of the concrete roadbed and frame body can be simplified by arranging along the longitudinal direction of the sleeper direct-connection track structure so as to abut against the construction, and the construction period can be shortened and construction can be easily performed. .

また、コンクリート道床に短繊維補強コンクリートを用いて無筋構造としているので、耐塩害性を高くできるとともに、コンクリート道床をより薄く構成することが可能となる。   In addition, since the concrete roadbed is made of short fiber reinforced concrete and has an unreinforced structure, the salt damage resistance can be increased and the concrete roadbed can be made thinner.

The following embodiments do not limit the invention according to each claim, and all combinations of features described in the embodiments are not necessarily essential to the solution means of the invention. .

It is a top view for demonstrating.

図１に示すように、本実施形態に係るまくらぎ直結軌道構造１は、略等間隔に配列されたまくらぎ１０をコンクリート道床２０で支持している。まくらぎ１０はＰＣまくらぎを用いると好適である。また、まくらぎ１０には、まくらぎ１０の配列方向に沿って一対の軌道レール２が取り付けられており、この軌道レール２を鉄道車両などが走行可能に構成されている。   As shown in FIG. 1, the sleeper direct connection track structure 1 according to the present embodiment supports sleepers 10 arranged at substantially equal intervals by a concrete roadbed 20. The sleeper 10 is preferably a PC sleeper. A pair of track rails 2 is attached to the sleeper 10 along the direction in which the sleepers 10 are arranged, and the track rail 2 is configured such that a rail vehicle or the like can travel.

コンクリート道床２０は、まくらぎ１０の長手方向の長さと略同一に即ち、長手方向の長さ内に形成されており、まくらぎ１０の肩部１０ａには施工されていない。即ち、図２に示すように、まくらぎ１０の肩部１０ａにはコンクリート道床２０が施工されず、まくらぎ１０の肩部１０ａが露出している。なお、まくらぎ１０の底面１０ｃは、長手方向に沿ってコンクリート道床２０が施工されており、軌道レール２からの荷重を負荷している。   The concrete roadbed 20 is formed substantially the same as the length of the sleeper 10 in the longitudinal direction, that is, within the length in the longitudinal direction, and is not applied to the shoulder 10 a of the sleeper 10. That is, as shown in FIG. 2, the concrete roadbed 20 is not applied to the shoulder 10 a of the sleeper 10, and the shoulder 10 a of the sleeper 10 is exposed. Note that a concrete roadbed 20 is constructed along the longitudinal direction of the bottom surface 10 c of the sleeper 10 and loads a load from the track rail 2.

さらに、コンクリート道床２０は、短繊維補強コンクリートを用いた無筋構造で構成されている。このように本実施形態に係るまくらぎ直結軌道構造１は、コンクリート道床２０が短繊維補強コンクリートを用いた無筋構造であるため、剛性を確保つつ、耐塩害性が向上している。また、無筋構造であるために鉄筋とのかぶりを確保する必要がなく、コンクリート道床２０の薄型化を図ることができる。   Furthermore, the concrete roadbed 20 is constituted by an unreinforced structure using short fiber reinforced concrete. As described above, the sleeper direct-connection track structure 1 according to the present embodiment has an unreinforced structure in which the concrete roadbed 20 uses short fiber reinforced concrete, and thus the salt damage resistance is improved while ensuring rigidity. Moreover, since it is an unreinforced structure, it is not necessary to ensure the cover with a reinforcing bar, and the concrete road floor 20 can be made thin.

図３に示すように、まくらぎ１０の側面１０ｂ及び底面１０ｃには、側面１０ｂと当接する第１の弾性材１３ｂと、底面１０ｃと当接する第２の弾性材１３ａとからなる弾性材１３が貼り付けられている。弾性材１３は、スチレンブタジエンゴムなどのような安価且つ薄い加硫ゴムを用いると好適である。   As shown in FIG. 3, on the side surface 10b and the bottom surface 10c of the sleeper 10, there is an elastic material 13 composed of a first elastic material 13b that contacts the side surface 10b and a second elastic material 13a that contacts the bottom surface 10c. It is pasted. The elastic material 13 is preferably made of inexpensive and thin vulcanized rubber such as styrene butadiene rubber.

また、図４に示すように、第１の弾性材１３ｂは、まくらぎ１０の側面１０ｂの少なくともいずれか一方が第２の弾性材１３ａよりもまくらぎ１０の底部側へ突出した突出部１３ｃを備えている。このように突出部１３ｃを構成することで、コンクリート道床２０とまくらぎ１０を一体化すると共に、第１の弾性材１３ｂがコンクリート道床２０のひび割れ誘発目地を兼ねている。なお、突出部１３ｃは、図４に示すように、コンクリート道床２０の高さ方向の途中まで延在しても構わないし、コンクリート道床２０の厚さいっぱいまで延在させても構わない。さらに、両側面１０ｂ，１０ｂと当接する第１の弾性材１３ｂ，１３ｂの両方に突出部１３ｃをそれぞれ形成しても構わない。   Further, as shown in FIG. 4, the first elastic member 13b has a protruding portion 13c in which at least one of the side surfaces 10b of the sleeper 10 protrudes toward the bottom side of the sleeper 10 rather than the second elastic member 13a. I have. By configuring the protruding portion 13 c in this manner, the concrete roadbed 20 and the sleeper 10 are integrated, and the first elastic material 13 b also serves as a crack-inducing joint of the concrete roadbed 20. In addition, as shown in FIG. 4, the protrusion part 13c may be extended to the middle of the height direction of the concrete roadbed 20, and may be extended to the full thickness of the concrete roadbed 20. As shown in FIG. Furthermore, you may form the protrusion part 13c in both of the 1st elastic materials 13b and 13b contact | abutted with both side surfaces 10b and 10b, respectively.

図５に示すように、まくらぎ１０の側面１０ｂには、まくらぎ１０の幅寸法がまくらぎ１０の長手方向に沿って徐々に拡幅する拡幅部１１と、拡幅部１１の端部から長手方向に沿って幅寸法が縮幅する縮幅部１２とからなる凸部１４が形成されている。凸部１４は、まくらぎ１０の両側面１０ｂ、１０ｂに幅方向に突出するように一対形成されると共に、長手方向に沿って２組，合計で４か所に形成されている。   As shown in FIG. 5, on the side surface 10 b of the sleeper 10, the widened portion 11 in which the width dimension of the sleeper 10 gradually widens along the longitudinal direction of the sleeper 10, and the longitudinal direction from the end of the widened portion 11. The convex part 14 which consists of the reduced width part 12 which a width dimension reduces along is formed. A pair of convex portions 14 are formed on both side surfaces 10b and 10b of the sleeper 10 so as to protrude in the width direction, and two sets along the longitudinal direction are formed at a total of four locations.

このように、本実施形態に係るまくらぎ直結軌道構造１は、まくらぎ１０の側面に凸部１４を形成しているので、肩部１０ａにコンクリート道床２０を施工することなく、まくらぎ１０を長手方向に保持することができる。   Thus, since the sleeper direct connection track structure 1 which concerns on this embodiment has formed the convex part 14 in the side surface of the sleeper 10, the sleeper 10 is constructed without constructing the concrete roadbed 20 in the shoulder part 10a. It can be held in the longitudinal direction.

なお、凸部１４を拡幅部１１と縮幅部１２とで構成することで、まくらぎ１０内の鉄筋のかぶりを確保することができ、まくらぎ１０の剛性を十分に確保することができると共に、徐々に縮径及び拡径する構造とすることで、凸部１４からコンクリート道床２０に列車荷重を伝達することができる。   In addition, by comprising the convex part 14 with the wide part 11 and the narrow part 12, the cover of the reinforcing bar in the sleeper 10 can be secured, and the rigidity of the sleeper 10 can be sufficiently secured. The train load can be transmitted from the convex portion 14 to the concrete roadbed 20 by gradually reducing the diameter and increasing the diameter.

なお、本実施形態に係るまくらぎ直結軌道構造１は、以下の施工方法で施工することができる。図６に示すように、路盤に所定の間隔で配置したまくらぎ１０の肩部１０ａに当接する枠体３０を配置する。枠体３０は、板材を用いることができ、まくらぎ１０と当接する反対面をバラスト４０によって押さえられている。また、所定の間隔で目地材１５をまくらぎ１０の長手方向に沿って配置する。この状態で、まくらぎ１０の側面１０ｂ及び枠体３０で画成された空間に短繊維補強コンクリートの打込みを行う。   In addition, the sleeper direct connection track structure 1 which concerns on this embodiment can be constructed with the following construction methods. As shown in FIG. 6, a frame body 30 that contacts the shoulder portion 10 a of the sleeper 10 disposed at a predetermined interval on the roadbed is disposed. A plate member can be used for the frame body 30, and the opposite surface in contact with the sleeper 10 is pressed by the ballast 40. Further, the joint material 15 is arranged along the longitudinal direction of the sleeper 10 at a predetermined interval. In this state, short fiber reinforced concrete is driven into the space defined by the side surface 10 b of the sleeper 10 and the frame body 30.

この施工方法によれば、コンクリート道床２０の打込み前に鉄筋を配筋することがなく、コンクリート道床２０の型枠も板材をまくらぎ１０の配列方向に沿って配置するだけなので、型枠の作成作業が大幅に簡素化できる。   According to this construction method, reinforcing bars are not arranged before the concrete roadbed 20 is driven, and the formwork of the concrete roadbed 20 is simply arranged along the direction in which the sleepers 10 are arranged. Work can be greatly simplified.

なお、コンクリート道床２０の打込み後は、枠体３０及びバラスト４０は撤去することもできるが、そのまま残しておいても構わない。この場合、バラスト４０による吸音効果を図ることができる。   After the concrete roadbed 20 is driven, the frame body 30 and the ballast 40 can be removed, but may be left as they are. In this case, the sound absorption effect by the ballast 40 can be achieved.

以上、説明した本実施形態に係るまくらぎ直結軌道構造１は、コンクリート道床２０に短繊維補強コンクリートを用いた無筋構造としているので、施工時に配筋作業を行うことがなく、施工期間を大幅に短縮することができると共に、コンクリート道床２０の薄型化を図ることができる。また、無筋構造とすることで沿岸部で問題となる耐塩害性を良好とすることができる。   As described above, the sleeper direct-connection track structure 1 according to the present embodiment has an unreinforced structure using short fiber reinforced concrete for the concrete roadbed 20, so that no reinforcement work is performed at the time of construction, and the construction period is greatly increased. The concrete roadbed 20 can be made thinner. Moreover, the salt damage resistance which becomes a problem in a coastal part can be made favorable by setting it as an unstrained structure.

また、まくらぎ１０の肩部１０ａにコンクリート道床２０を施工しないので、型枠の施工も大幅に簡素化することができ、施工期間を短縮することができる。さらに、まくらぎ１０の側面１０ｂに凸部を形成しているので、肩部１０ａにコンクリート道床２０を施工せずに、まくらぎ１０をまくらぎ１０の長手方向に保持することができる。   Moreover, since the concrete roadbed 20 is not constructed on the shoulder 10a of the sleeper 10, the construction of the formwork can be greatly simplified, and the construction period can be shortened. Furthermore, since the convex part is formed in the side surface 10b of the sleeper 10, the sleeper 10 can be hold | maintained in the longitudinal direction of the sleeper 10 without constructing the concrete roadbed 20 in the shoulder part 10a.

さらに、凸部１４は、拡幅部１１と縮幅部１２とから構成されているので、まくらぎ１０内の鉄筋のかぶりを確保できるので剛性を確保することができ、凸部１４からコンクリート道床２０に列車荷重を伝達することができる。   Furthermore, since the convex part 14 is comprised from the wide part 11 and the reduced width part 12, since the cover of the reinforcing bar in the sleeper 10 can be ensured, rigidity can be ensured and the concrete roadbed 20 from the convex part 14 can be ensured. Train load can be transmitted to

なお、上述した本実施形態に係るまくらぎ直結軌道構造１では、凸部１４は、まくらぎ１０の両側面１０ｂ，１０ｂの長手方向の両端側に合計４箇所形成した場合について説明を行ったが、凸部は、これに限られず、凸部は、側面１０ｂに少なくとも一か所ずつ形成されていればよく、例えば、長手方向の略中央部に一か所ずつ形成しても構わないし、長手方向に沿って３か所以上形成しても構わない。その様な変更又は改良を加えた形態も本発明の技術的範囲に含まれうることが、特許請求の範囲の記載から明らかである。   In addition, in the sleeper direct connection track structure 1 according to the above-described embodiment, a case has been described in which the convex portions 14 are formed at a total of four locations on both ends 10b and 10b in the longitudinal direction of the sleeper 10 in the longitudinal direction. The convex portion is not limited to this, and the convex portion only needs to be formed at least one place on the side surface 10b. For example, the convex portion may be formed one place at a substantially central portion in the longitudinal direction. You may form three or more places along a direction. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
