Description
【０００１】[0001]
本考案は、鉄道の架線等の修理や軌道の補修などに好適に使用できるように工 事用車両を軌道上に進入させて、その工事用車両の作業性を向上できる軌道工事 用ブロックに関するものである。 The present invention relates to a track construction block capable of improving the workability of a construction vehicle by allowing a construction vehicle to enter the track so that it can be suitably used for repairing railway overhead lines and repairing tracks. Is.
【０００２】[0002]
近年、鉄道の軌道や架線の修理や補修工事等において、軌道上を移動して、そ れらの工事をより迅速に完了するために、一般道路と軌条上とを走行できるよう にトラック等に軌道用の車輪を備えた工事用車両が使用されるようになってきて いる。 In recent years, in repairing and repairing railway tracks and overhead lines, in order to move along the tracks and complete these works more quickly, trucks and other equipment must be installed so that they can run on ordinary roads and rails. Construction vehicles equipped with orbital wheels have come into use.
【０００３】 そのような工事用車両を軌道上に進入させ、その軌道の軌条への損傷を防止す るために、従来では、例えば図４に示すように、軌道２１上をその工事用車両が 乗り上げるため、木製などの枕木２２を台として用いている。In order to prevent such a construction vehicle from entering the track and prevent damage to the rail of the track, conventionally, as shown in FIG. 4, for example, as shown in FIG. A sleeper 22 made of wood or the like is used as a stand for riding.
【０００４】 その使用方法は、適当な大きさに切断された枕木２２を軌道２１の軌条に対し て挟んで、前記工事用車両の左右のタイヤ間隔に合わせて２列平行に並べ、さら に、工事用車両をそれら枕木２２上に乗り上げ易くするために、それらの各両端 側に傾斜面を形成するように砕石２３をそれぞれ積み上げていた。The method of use is to sandwich sleepers 22 cut into an appropriate size between the rails of the track 21 and to arrange them in two rows in parallel according to the left and right tire intervals of the construction vehicle. In order to make it easier for the construction vehicle to ride on the sleepers 22, the crushed stones 23 were piled up so that inclined surfaces were formed on both end sides thereof.
【０００５】[0005]
ところが、上記従来のような枕木２２を用いるのでは、その重量が重いため、 運搬、設置の作業に手間取り、その上、軌道２１に沿って工事する場合、工事用 車両の移動に伴って、その都度、工事用車両を軌道２１から外した後、枕木２２ を、次の工事位置まで運搬・設置するため、その工事用車両の移動に手間取ると いう問題を生じている。 However, the use of the sleepers 22 as in the above-described conventional ones is heavy, so that it takes time to carry out the work for transportation and installation, and when the construction along the track 21 is performed, the Since each time the construction vehicle is removed from the track 21 and the sleeper 22 is transported and installed to the next construction position, there is a problem that it takes time to move the construction vehicle.
【０００６】[0006]
本考案の軌道工事用ブロックは、以上の課題を解決するために、発泡樹脂成形 板が軌道の軌条間に嵌まり込んで上記各軌条の上面とほぼ面一となるように成形 されると共に、上記発泡樹脂成形板を並設する板状体が上記各発泡成形板の厚さ 方向両端面にそれぞれ接着され、かつ、上記各発泡樹脂成形板間に、押圧による 上記板状体の湾曲に応じて伸縮する間隙が形成されていることを特徴としている 。 In order to solve the above problems, the block for track construction of the present invention is formed so that the foamed resin molding plate is fitted between the rails of the track and is substantially flush with the upper surface of each rail. Plate-shaped bodies in which the foamed resin molded plates are juxtaposed are adhered to both end faces in the thickness direction of the foamed molded plates, respectively, and depending on the curvature of the plate-shaped bodies due to pressing between the foamed resin molded plates. It is characterized by forming a gap that expands and contracts.
【０００７】[0007]
上記の構成によれば、軌道の軌条間に嵌まり込んで上記各軌条の上面とほぼ面 一となるように成形された発泡樹脂成形板を並設しているから、軌条間に嵌め込 むことができ、その上、それらの厚さ方向両端面に板状体が接着されていて、工 事用車両等の荷重が上記板状体を介して各発泡樹脂成形板にかかっても、その荷 重が板状体により分散されて、上記各発泡樹脂成形板の荷重による破損等を防止 することができる。 According to the above configuration, since the foamed resin molded plates that are molded so as to fit between the rails of the tracks and to be substantially flush with the upper surfaces of the rails are arranged side by side, fit between the rails. In addition, plate-like bodies are adhered to both end faces in the thickness direction thereof, and even if a load of an industrial vehicle or the like is applied to each foamed resin molded plate through the plate-like body, The load is dispersed by the plate-like body, so that it is possible to prevent the foamed resin molded plate from being damaged by the load.
【０００８】 また、軌道上の不陸等による上記荷重による押圧も板状体により分散できて、 その押圧による破損等も防止できる。さらに、その荷重や押圧により板状体が撓 んで湾曲しても、各発泡樹脂成形板間に設けられた間隙により、各発泡樹脂成形 板の長さ方向への圧縮力も軽減できて、各発泡樹脂成形板の損傷を回避できる。Further, the pressing due to the above-mentioned load due to unevenness on the track or the like can be dispersed by the plate-like body, and damage due to the pressing can be prevented. Furthermore, even if the plate-shaped body bends and bends due to the load or pressure, the gap provided between each foamed resin molded plate can reduce the compressive force in the lengthwise direction of each foamed resin molded plate, and It is possible to avoid damage to the resin molding plate.
【０００９】 これにより、上記構成は、軌条の損傷等の悪影響を回避しながら工事用車両等 を軌道上に乗り上げることができ、また、工事用車両等を板状体上で軌条に沿っ て移動しても、その荷重に耐えることができる。[0009] Thus, with the above configuration, the construction vehicle or the like can be ridden on the track while avoiding adverse effects such as damage to the rail, and the construction vehicle or the like can be moved along the track on the plate-shaped body. However, it can withstand the load.
【００１０】 したがって、上記構成は、従来より、工事用車両等の移動が迅速化できるので 、補修工事等が容易となり、その上、発泡樹脂成形板を軽量とすることができて 、運搬や設置も従来より容易となるので、補修工事等の作業性を向上させること が可能となる。Therefore, with the above-described structure, since the construction vehicle can be moved more quickly than before, repair work and the like can be facilitated, and in addition, the foamed resin molded plate can be made lightweight, and can be transported and installed. Since it will be easier than before, it will be possible to improve workability such as repair work.
【００１１】[0011]
本考案の一実施例について図１ないし図３に基づいて説明すれば、以下の通り である。 軌道工事用ブロックには、図１および図２に示すように、成形性や圧縮強度に 優れた発泡樹脂であるスチレン改質ポリエチレン発泡樹脂を略長方形板状に成形 した発泡樹脂成形板１が使用され、その形状は、軌道４における軌条４ａの間隔 や高さに応じて成形され、例えば、長さ 950mm、幅 490mm、厚さ 166mmに成形さ れる。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. As shown in Figs. 1 and 2, the block for track construction uses a foamed resin molded plate 1 made by molding a styrene-modified polyethylene foamed resin, which is a foamed resin excellent in moldability and compressive strength, into a substantially rectangular plate shape. The shape is formed in accordance with the interval and height of the rails 4a in the track 4, for example, the length is 950 mm, the width is 490 mm, and the thickness is 166 mm.
【００１２】 さらに、後述するよう軌道４における軌条４ａの押さえ板やボルト等の突出部 ４ｂとの接触を回避できるように、その長さ方向両端部に厚さが半分で、その長 さ方向端面から入り込んだ長さが、例えば75mmの切欠部１ａが形成されている。Further, as will be described later, in order to avoid contact with the pressing plate of the rail 4a on the track 4 and the projecting portion 4b such as a bolt, the thickness is half at both ends in the length direction, and the end face in the length direction is formed. A cut-out portion 1a having a length of 75 mm, for example, is formed.
【００１３】 そして、上記発泡樹脂成形板１を四個、支え板２により並設してブロック３が 形成されている。このようなブロック３は、各発泡樹脂成形板１の長さ方向両端 面をそれぞれ一直線上となり、かつ、各切欠部１ａが面するように一列に並設し て備え、さらに、例えば厚さ９mmの合板からなる支え板２を上記各発泡樹脂成形 板１の厚さ方向両端面にそれぞれ接着されてなっている。A block 3 is formed by arranging four foamed resin molded plates 1 side by side with a support plate 2. Such a block 3 is provided in such a manner that both end surfaces in the length direction of each foamed resin molded plate 1 are aligned in a straight line and are arranged in a line so that each notch 1a faces, and further, for example, a thickness of 9 mm. A support plate 2 made of plywood is adhered to both end faces in the thickness direction of the foamed resin molded plate 1.
【００１４】 その上、ブロック３では、各発泡樹脂成形板１間に所定の間隙１ｂが形成され ていて、支え板２の荷重等による押圧による変形、例えば湾曲による発泡樹脂成 形板１への圧縮応力が軽減できるようになっている。なお、上記の間隙１ｂは、 中央部の間隙１ｂで、例えば14mm、他の間隙１ｂで、例えば13mmに設定されてい る。In addition, in the block 3, a predetermined gap 1b is formed between the foamed resin molded plates 1, and the support plate 2 is deformed by a pressure applied by the load or the like, for example, curved to the foamed resin molded plate 1. The compressive stress can be reduced. The gap 1b is set to 14 mm in the central gap 1b and 13 mm in the other gaps 1b.
【００１５】 したがって、上記ブロック３は、例えば、上述した発泡樹脂成形板１の各寸法 例を用いると、長さ2000mm、幅 950mm、厚さ 184mmの略長方形板状となって、鉄 道等の軌道４における軌条４ａ間に嵌め込んで、各軌条４ａの上面と略面一、な いしは、それら軌条４ａの上面から若干高くなるように設定されている。Therefore, the block 3 is, for example, using the above-mentioned examples of the dimensions of the foamed resin molded plate 1, becomes a substantially rectangular plate shape having a length of 2000 mm, a width of 950 mm, and a thickness of 184 mm, and is used as an iron road or the like. It is fitted between the rails 4a of the track 4 so as to be substantially flush with the upper surfaces of the rails 4a, or to be slightly higher than the upper surfaces of the rails 4a.
【００１６】 上記各発泡樹脂成形板１は、ポリエチレン樹脂粒子にスチレンモノマーを重合 してスチレン改質樹脂を得た後、そのスチレン改質樹脂に発泡剤を含浸させた発 泡性樹脂粒子を、成形型内に充填し、蒸気などの加熱媒体により加熱し、所定発 泡倍率に膨張させて得られるスチレン改質ポリエチレン発泡樹脂成形体〔商品名 ：ピオセラン、積水化成品工業（株）製〕である。Each of the foamed resin molded plates 1 described above is prepared by polymerizing polyethylene resin particles with a styrene monomer to obtain a styrene-modified resin, and then impregnating the styrene-modified resin with a foaming agent to obtain foamable resin particles. Styrene-modified polyethylene foamed resin molded product (trade name: PIOCELAN, manufactured by Sekisui Plastics Co., Ltd.) obtained by filling in a mold, heating it with a heating medium such as steam, and expanding it to a predetermined foaming ratio is there.
【００１７】 なお、上記実施例では、そのスチレン改質ポリエチレン発泡樹脂の発泡倍率15 倍の成形体（見掛け比重、0.067g/cm3程度）を用いており、その圧縮強度は、そ れを JIS Ｋ6767により測定したところ、規定ひずみ10％で 3.5kg/cm2、規定ひ ずみ25％で 4.0kg/cm2、規定ひずみ50％で 5.1kg/cm2であった。In the above examples, a molded product (apparent specific gravity, about 0.067 g / cm 3 ) of the styrene-modified polyethylene foamed resin having a foaming ratio of 15 times is used, and the compression strength thereof is JIS K6767 was measured by, 3.5 kg / cm 2 at a specified strain 10%, 4.0kg / cm 2 with 25% Zumi shed defined, it was 5.1 kg / cm 2 at a prescribed strain of 50%.
【００１８】 その上、前記ブロック３は、その幅方向に形成されてその幅方向両端に達する 間隙１ｂが、複数、所定の間隔で相互に平行に設けられているから、ブロック３ は可撓性を備えており、ブロック３への荷重による支え板２の湾曲等の変形によ る発泡樹脂成形板１の破損が軽減される。Moreover, since the block 3 has a plurality of gaps 1b which are formed in the width direction thereof and reach both ends in the width direction and are parallel to each other at a predetermined interval, the block 3 is flexible. Is provided, and damage to the foamed resin molded plate 1 due to deformation of the support plate 2 such as bending due to the load on the block 3 is reduced.
【００１９】 なお、発泡樹脂成形板１には、所定の圧縮強度、例えば２kg/cm2以上の圧縮強 度（規定ひずみ、25％）を備えた発泡樹脂成形体であれば、前記のスチレン改質 ポリエチレン発泡樹脂に限らず、エチレンまたはプロピレンの単独重合体、エチ レン−プロピレン、エチレン−酢酸ビニルの共重合体などのポリオレフィン系樹 脂、スチレン系樹脂などの発泡樹脂成形体を使用してもよい。If the foamed resin molded plate 1 is a foamed resin molded body having a predetermined compression strength, for example, a compression strength of 2 kg / cm 2 or more (specified strain, 25%), the styrene modified Not only polyethylene foam resin, but also polyolefin resin such as ethylene or propylene homopolymer, ethylene-propylene, ethylene-vinyl acetate copolymer, or foamed resin molding such as styrene resin can be used. Good.
【００２０】 また、支え板２としては、ベニヤ板等の合板や木材の一枚板、あるいは、所定 の強度を有するゴム等からなる樹脂板を使用してもよい。Further, as the support plate 2, a plywood such as a veneer plate, a single plate of wood, or a resin plate made of rubber or the like having a predetermined strength may be used.
【００２１】 したがって、上記実施例の構成では、支え板２の見掛け比重が、0.54ｇ/cm3程 度で、各発泡樹脂成形板１の見掛け比重が 0.067ｇ/cm3程度であるので、前記ブ ロック３の重量は36kg程度となる。Therefore, in the configuration of the above-mentioned embodiment, since the apparent specific gravity of the supporting plate 2 is about 0.54 g / cm 3 and the apparent specific gravity of each foamed resin molded plate 1 is about 0.067 g / cm 3 , Block 3 weighs about 36 kg.
【００２２】 このような上記軌道工事用ブロックの使用法としては、図１に示すように、鉄 道などの軌道４の各軌条４ａ間に各ブロック３を、各軌条４ａの長手方向に沿っ て、相互に隣接するように置く。このような運搬・設置作業は、各ブロック３が 軽量なため、２名の作業員により容易に可能である。As shown in FIG. 1, as a method of using such a track construction block, each block 3 is provided between each track 4a of a track 4 such as a railroad track along the longitudinal direction of each track 4a. , Put them next to each other. Since each block 3 is lightweight, such transportation / installation work can be easily performed by two workers.
【００２３】 このようにして軌道４の軌条４ａ間に各ブロック３が載置された後、図３に示 すように、各軌条４ａ上に工事用車両である軌道工事用トラック７を、各軌条４ ａへの障害を回避して乗り上げるため、外方に向かって低くなる傾斜を形成する ように高さの異なる乗上用枕木８…を軌条４ａの外側に沿って並べ、もしくは、 図示しないが、傾斜部と板状体を両面に備える発泡成形体を軌条４ａの外側に沿 って、上記と同様に並べる。After each block 3 is placed between the rails 4a of the track 4 in this way, as shown in FIG. 3, a track construction truck 7 which is a construction vehicle is mounted on each rail 4a. In order to avoid the obstacle on the rail 4a and get on, the riding sleepers 8 having different heights are arranged along the outside of the rail 4a so as to form a slope that becomes lower toward the outside, or not shown. However, the foamed molded product having the inclined portion and the plate-shaped body on both sides is arranged along the outside of the rail 4a in the same manner as described above.
【００２４】 次に、前記の軌道工事用トラック７を各ブロック３上に乗り上げて、各ブロッ ク３上を軌条４ａに沿って進めて、順次、補修工事等を進めることができる。こ れにより、上記実施例の構成は、一般道路も走行できる軌道工事用トラック７を 用いることができるため、補修用等の器具や補修材等を、運搬用のトラックから 軌道用車両に積み替える手間を省くことができる。Next, the track construction truck 7 can be ridden on each block 3 and advanced on each block 3 along the rail 4a, so that repair work can be sequentially performed. As a result, the configuration of the above-described embodiment can use the track construction truck 7 that can also drive on general roads, and therefore equipment for repairs, repair materials, etc. can be transshipped from a transportation truck to a track vehicle. You can save time.
【００２５】 また、通過後の各ブロック３は、順次取り出して、進行方向の軌条４ａ間に運 搬して設置すればよい。この際にも、各ブロック３が軽量なため、少ない作業員 により容易に運搬・設置が可能である。The blocks 3 after passing may be taken out one after another, transported between the rails 4a in the traveling direction, and installed. Also in this case, since each block 3 is lightweight, it can be easily transported and installed by a small number of workers.
【００２６】 よって、上記実施例の構成は、軌道工事用トラック７の移動も、従来のように 枕木を積み替えていた場合と比べて、大幅に迅速化できて、軌道４の補修工事、 軌道４上の架線工事、軌条４ａの交換や補修、軌道４における砕石６の補修など の軌道工事の作業性を向上できる。Therefore, in the configuration of the above-described embodiment, the movement of the track construction track 7 can be significantly speeded up as compared with the conventional case where the sleepers are re-loaded, and the repair work of the track 4 and the track 4 are performed. It is possible to improve workability of track work such as overhead wire work, replacement and repair of rail 4a, repair of crushed stone 6 on track 4.
【００２７】 このようなブロック３は、軌道工事用トラック７の６本あるタイヤの各ブロッ ク３に対する総当接面積が2000cm2 程度であるので、４トン程度の重量まで耐え ることができ、また、上記の軌道工事用トラック７の総重量は３トン程度である ので、上記ブロック３は充分にその重量に耐えることができる。The block 3 as described above has a total contact area of about 2000 cm 2 with respect to each block 3 of the six tires of the track construction truck 7, and therefore can bear a weight of about 4 tons, Moreover, since the total weight of the track construction truck 7 is about 3 tons, the block 3 can sufficiently bear the weight.
【００２８】 このようにしてブロック３が使用され、軌道工事用トラック７の入ることので きる位置であれば、その軌道工事用トラック７にブロック３を積載して運搬でき るから、どのような軌道４上にも、上記の各ブロック３を用いて軌道工事用トラ ック７を移動させることが可能となる。In this way, if the block 3 is used and the track construction truck 7 can enter the block 3, the block 3 can be loaded on the track construction truck 7 and transported. It is possible to move the track 7 for track construction on each of the blocks 4 using the blocks 3 described above.
【００２９】 ところで、従来では、軌条内の中込め材として木製等の枕木を用いていたため 、その重量が重く、踏切板の運搬や設置に手間取り、その上、その設置等の作業 中に、例えば足の上にその枕木を落としたりすると、大きな傷害を起こし易かっ た。By the way, in the past, since sleepers such as wood were used as the filling material in the rails, the weight thereof was heavy, and it took time to transport and install the crossing plate, and further, during work such as installation, for example, Dropping the sleeper on the foot was likely to cause serious injury.
【００３０】 しかしながら、上記実施例のブロック３では、その重量が軽く、作業員による 各ブロック３の運搬や設置は容易なものとなり、また、そのような軽量のブロッ ク３を、作業中、万が一例えば足の上に落としても、大きな傷害に至ることが回 避できる。However, in the block 3 of the above-mentioned embodiment, the weight thereof is light, which facilitates the transportation and installation of each block 3 by the worker. In addition, such a light block 3 should be used during the operation. For example, dropping it on the foot can prevent serious injury.
【００３１】 その上、各ブロック３の厚さ方向両端面に支え板２が貼り付けられているので 、砕石６上のように平面ではなく凸凹形状の面に各ブロック３が載置されても、 各発泡樹脂成形板１部分が変形したり、破損したりすることはない。Moreover, since the support plates 2 are attached to both end faces of each block 3 in the thickness direction, even if each block 3 is placed on an uneven surface instead of a flat surface like the crushed stone 6. The foamed resin molded plate 1 portion is not deformed or damaged.
【００３２】 また、ブロック３は、隙間１ｂ…を備えているため、可撓性に優れ、図１に示 すように、砕石６上や枕木５と砕石６との境目のように不陸にも追随して、破損 を防止できるから、種々な設置面の状態への適用を拡大できる。Further, since the block 3 is provided with the gaps 1b, it is excellent in flexibility, and as shown in FIG. 1, the block 3 becomes uneven like the boundary between the crushed stone 6 and the sleeper 5 and the crushed stone 6. The damage can be prevented and the application to various installation surface conditions can be expanded.
【００３３】 その上、ブロック３では、切欠部１ａが設けられて、軌条４ａの押さえ板やボ ルト等の突出部４ｂとの接触を回避できるから、それらと当接することによって 、荷重時に、それらとの当接点に集中する荷重による発泡樹脂成形板１の破損を 防止でき、かつ、その切欠部１ａに容易に手を差し込むことができて、ブロック ３の運搬を容易なものとしている。よって、上記ブロック３は、従来より使用勝 手の良いものとなっている。Moreover, since the block 3 is provided with the notch 1a, it is possible to avoid contact with the protrusion 4b such as the pressing plate or the bolt of the rail 4a. It is possible to prevent the foamed resin molded plate 1 from being damaged by a load concentrated on the contact point with the and to easily insert the hand into the notch 1a, so that the block 3 can be easily transported. Therefore, the block 3 is easier to use than the conventional one.
【００３４】 なお、各発泡樹脂成形板１および支え板２から成るブロック３の形状や、その ブロック３における用いる発泡樹脂成形板１の数量は、上記のように限定される ものではなく、作業員が運搬できる大きさおよび重さの範囲内で、軌条４ａ間の 間隔や高さに応じて変更できる。The shape of the block 3 including the foamed resin molded plate 1 and the support plate 2 and the number of the foamed resin molded plate 1 used in the block 3 are not limited as described above, but are not limited to those of the worker. It can be changed according to the distance and height between the rails 4a within the range of the size and weight that can be transported by
【００３５】[0035]
本考案の軌道工事用ブロックは、以上のように、発泡樹脂成形板が軌道の軌条 間に嵌まり込んで上記各軌条の上面とほぼ面一となるように成形されると共に、 上記発泡樹脂成形板を並設する板状体が上記各発泡成形板の厚さ方向両端面にそ れぞれ接着され、かつ、上記各発泡樹脂成形板間に、押圧による上記板状体の湾 曲に応じて伸縮する間隙が形成されている構成である。 As described above, the track construction block of the present invention is formed such that the foamed resin molded plate is fitted between the rails of the track so as to be substantially flush with the upper surface of each of the rails. The plate-shaped bodies in which the plates are arranged in parallel are adhered to both end faces in the thickness direction of the foam-molded plates, respectively, and depending on the bending of the plate-shaped bodies due to pressing between the foam-molded resin plates. In this configuration, a gap that expands and contracts is formed.
【００３６】 それゆえ、上記構成は、工事用車両等を軌道上に乗り上げても、軌条の損傷等 の悪影響を回避でき、また、発泡樹脂成形板を軽量とすることができて、運搬や 設置も従来より容易化、かつ迅速化できるので、軌条に沿った工事用車両等の移 動をより迅速化できる。Therefore, the above configuration can avoid adverse effects such as rail damage even when a construction vehicle or the like is put on the track, and can reduce the weight of the foamed resin molded plate for transportation or installation. Since it can be made easier and faster than before, the movement of construction vehicles along the track can be made faster.
【００３７】 この結果、上記構成は、補修工事等が容易となり、かつ、補修工事等の作業性 を向上させることが可能となるという効果を奏する。As a result, the above configuration has an effect that the repair work and the like can be facilitated and the workability of the repair work and the like can be improved.
