Description

本発明は、鉄道踏切のゴム製舗装板およびそのゴムパッド、特に排水構造を有するゴム製舗装板およびゴム製舗装板とレールの間に詰めるゴムパッドに関する。 The present invention relates to a rubber paving board for railroad crossings and its rubber pad, and more particularly to a rubber paving board having a drainage structure and a rubber pad packed between the rubber paving board and a rail.

図１に示す鉄道踏切に敷設した舗装板の説明図を参照されたい。一般の鉄道踏切の軌道は、鉄道車両が脱線することなく安全走行できるように、使用する鉄道車両の車輪の外形寸法に合わせるため、２本のレール１０の内側に凹溝形状の輪縁溝１１を設けなければならない。しかし、この設計は踏切に溝状の障害をつくり、潜在的危険因子となり、人やオートバイの乗り手を絶えず危険にさらす。 Please refer to the illustration of the pavement laid at the railroad crossing shown in FIG. The railroad crossing track of a general railway crossing is formed with a groove-shaped annular groove 11 inside the two rails 10 in order to match the outer dimensions of the wheels of the railway vehicle to be used so that the railway vehicle can travel safely without derailing. Must be provided. However, this design creates a groove-like obstacle at the level crossing, creating a potential risk factor and constantly putting people and motorcycle riders at risk.

また、踏切の路面にアスファルトを敷設するものもあるが、この路面は常に大型車両の圧力を受けるため軌道内側の輪縁部位のアスファルトがしばしば脱落し、路面が凹んだり凸凹になったりする。特にオートバイの乗り手が斜め交差踏切を通過するときに、オートバイの車輪が輪縁溝にはまる転倒事故がしばしば起きる。 In addition, asphalt is laid on the road surface of a railroad crossing, but since this road surface is always subjected to the pressure of a large vehicle, the asphalt at the ring edge inside the track often falls off, and the road surface becomes concave or uneven. In particular, when a motorcycle rider passes through a crossing at a crossing, there are often accidents where the motorcycle wheel falls into the ring groove.

本発明は、鉄道踏切の軌道の２本のレール間に連結して敷設でき、ゴム製舗装板の底部に溜まった水を排出する設計となっており、さらに輪縁溝が平らに敷き詰められる鉄道踏切のゴム製舗装板およびそのゴムパッドを提供する。 The present invention is a railway that can be connected and laid between two rails of a railroad crossing track, is designed to discharge water accumulated at the bottom of a rubber pavement, and is further laid flat with an annular groove Providing rubber paving boards and rubber pads for level crossings.

本発明が提供する鉄道踏切のゴム製舗装板の技術的手段は、上面と底面を有し、両外側に肩部を有し、排水部材が設けられた舗装板本体と、上面と肩部の間の高低差によって形成され、各側に複数個の結合孔が設けられた２つの凹溝とを含む。 The technical means of the railroad crossing rubber pavement plate provided by the present invention includes a pavement plate body having a top surface and a bottom surface, shoulder portions on both outer sides and provided with drainage members, and a top surface and a shoulder portion. And two concave grooves each formed with a plurality of coupling holes on each side.

本発明が提供する鉄道踏切のゴムパッドの技術的手段は、ゴム製舗装板の凹溝内に嵌設され、上面と底面を有し、上面と底面の間に空洞の緩衝室を有するパッド本体と、パッド本体の底面に形成され、ゴム製舗装板の結合孔に対応し、パッド本体を凹溝に嵌設する際に結合孔に差し込まれる複数本の固定棒とを含む。 The technical means of the rubber pad for railroad crossings provided by the present invention includes a pad main body that is fitted in a concave groove of a rubber pavement plate, has a top surface and a bottom surface, and has a hollow buffer chamber between the top surface and the bottom surface. And a plurality of fixing rods formed on the bottom surface of the pad main body, corresponding to the coupling holes of the rubber pavement plate, and inserted into the coupling holes when the pad main body is fitted in the concave grooves.

本発明の特徴は、排水可能なゴム製舗装板を使用することにより、ゴム製舗装板底部の鉄道路床の底に水が溜まったときに、大型車両の強い圧力で緊急排水し、したがって、底部に溜まった水が原因となって強い圧力を受けたときに浮き上がって抜け、走行の安全に影響を与えることが避けられることである。また、空洞のゴムパッドは、鉄道車両の輪縁が圧力をかけて通過した後に原状復帰し、その底部の複数本の固定棒はゴム製舗装板の結合孔と接合し、しっかり係合しておけば緩んで抜けることが起こりにくい。 The feature of the present invention is that, by using a drainable rubber pavement board, when water accumulates on the bottom of the railway floor at the bottom of the rubber pavement board, emergency drainage is performed with strong pressure of a large vehicle, and therefore It is avoided that the water that has accumulated at the bottom rises and escapes when it receives a strong pressure and affects the safety of traveling. Also, the hollow rubber pad returns to its original state after the wheel edge of the railway vehicle passes under pressure, and the fixing rods at the bottom of the rubber pad are joined to the coupling holes of the rubber pavement and firmly engaged. If it is loose, it is difficult to come out.

The rubber pavement plate 20 includes a pavement plate main body 21 and two outer recessed grooves 30. The pavement board main body 21 has an upper surface 22 and a bottom surface 23, and has shoulders 24 on the outer sides corresponding to the two rails A of the pavement board main body 21, and the pavement board main body 21 has at least one drainage. A member 25 is provided, and the drainage member 25 may have a hole or a groove structure, and penetrates the entire pavement board main body 21. When the pavement board main body 21 receives pressure, the water accumulated in the railway floor is discharged from the drainage member 25. Two concave grooves 30 are respectively provided in each shoulder portion 24, and are formed by a height difference between the upper surface 22 and the two shoulder portions 24, and a plurality of coupling holes 31 are provided in the concave grooves 30 on each side. It has been.

上述の本実施形態のゴム製舗装板２０の上面２２に滑り止め部材２６が設けられ、これは、ゴム製舗装板の上面から突出した複数個の楕円形滑り止め粒２６１として設けることができ、これら楕円形滑り止め粒は間隔を置いて交錯して設けられる。もちろん楕円形の形状の他に別の形状や文字に置き換えてもよい。 An anti-slip member 26 is provided on the upper surface 22 of the above-described rubber pavement plate 20 of the present embodiment, which can be provided as a plurality of elliptical anti-slip particles 261 protruding from the upper surface of the rubber pavement plate, These oval antiskid grains are provided in a crossing manner at intervals. Of course, in addition to the elliptical shape, another shape or character may be substituted.

本実施形態のゴムパッド４０は、パッド本体４１と複数本の固定棒５０を含む。パッド本体４１は前記ゴム製舗装板２０に嵌設された前記凹溝３０内に対応し、前記パッド本体４１の上面４２と底面４３の間に空洞の緩衝室４４が形成され、複数本の固定棒５０が前記パッド本体４１の前記底面４３に形成され、これらの固定棒５０は前記ゴム製舗装板２０の前記複数の結合孔３１に対応し、前記パッド本体４１を前記凹溝３０に嵌設する際に前記結合孔３１に差し込まれ、肩部２４を貫通してこれを結合固定する。 The rubber pad 40 of the present embodiment includes a pad main body 41 and a plurality of fixing bars 50. The pad main body 41 corresponds to the inside of the concave groove 30 fitted to the rubber pavement plate 20, and a hollow buffer chamber 44 is formed between the upper surface 42 and the bottom surface 43 of the pad main body 41, and a plurality of fixed bodies are fixed. Bars 50 are formed on the bottom surface 43 of the pad main body 41, and these fixing bars 50 correspond to the plurality of coupling holes 31 of the rubber pavement plate 20, and the pad main body 41 is fitted in the concave groove 30. In this case, it is inserted into the coupling hole 31 and penetrates the shoulder portion 24 to be coupled and fixed.

前記固定棒５０の棒身はそれぞれテーパ状（ｔａｐｅｒ）に形成でき、また、末端にフック部材５１を有し、このフック部材５１はゴムパッド４０が外力により弾性変形したときにゴム製舗装板２０から抜けるのを防ぐことができる。具体的な構造は、突出した半球形５１１として設計でき、このようにすると、固定棒５０が結合するときに容易に結合孔３１に入る上、係合作用ももつ。また、上述の複数の固定棒５０は少なくとも３本であり、ゴムパッド４１が外力によって弾性変形したときに前後両端が反り返りやすいため、抜け落ちを防ぐためにこの固定棒５０の最初と最後の２本の棒身の長さを中間の固定棒５０の棒身より長くする。 Each of the rods of the fixing rod 50 can be formed in a taper shape, and has a hook member 51 at the end. The hook member 51 is separated from the rubber pavement plate 20 when the rubber pad 40 is elastically deformed by an external force. It can be prevented from coming off. The specific structure can be designed as a protruding hemispherical shape 511. In this way, when the fixing rod 50 is coupled, it easily enters the coupling hole 31 and also has an engaging action. In addition, since the above-described plurality of fixing rods 50 are at least three, and both the front and rear ends are likely to warp when the rubber pad 41 is elastically deformed by an external force, the first and last two rods of the fixing rod 50 are used to prevent falling off. The body length is made longer than that of the intermediate fixed rod 50.

図４に示す本発明のゴム製舗装板およびゴムパッドの実施形態のレール内側への使用の説明図と、図５に示す図４の軌道車輪外縁の圧迫による変形の説明図を参照されたい。上述のゴム製舗装板２０は複数個を連結して鉄道踏切の２本のレールＡ間に敷設することができ、各ゴム製舗装板２０は鉄道の枕木Ｂ上にちょうど跨置できる長さであり、その上面２２がレールの車輪当接面Ｄとほぼ平らになり、また２つの肩部２４を利用して２本のレールＡの内側立面に密着させることができる。上記ゴム製舗装板２０の材質は合成ゴムであり、外層は耐磨耗合成ゴムでよく、硬度はショアＡ硬さ（ＳｈｏｒｅＡ）７０、引張強さは１２０ｋｇ／ｃｍ²以上、最大伸長率は３５０％以上である。 Please refer to the explanatory view of the use of the embodiment of the rubber paving board and rubber pad of the present invention shown in FIG. 4 inside the rail, and the explanatory view of the deformation due to the compression of the outer edge of the track wheel shown in FIG. 4 shown in FIG. A plurality of the above-mentioned rubber pavement boards 20 can be connected and laid between the two rails A of the railroad crossing, and each rubber pavement board 20 has a length that can be just straddled on the railway sleepers B. The upper surface 22 of the rail is substantially flat with the wheel contact surface D of the rail, and the two shoulder portions 24 can be used to closely contact the inner vertical surfaces of the two rails A. The rubber pavement 20 may be made of synthetic rubber, the outer layer may be wear-resistant synthetic rubber, the hardness is Shore A 70, the tensile strength is 120 kg / cm ² or more, and the maximum elongation is 350% or more.

上記ゴムパッド４０のパッド本体４１の材質は合成ゴムであり、硬度はショアＡ硬さ（ＳｈｏｒｅＡ）５０、引張強さは２００ｋｇ／ｃｍ²以上、最大伸長率は５００％以上である。固定棒５０の材質は硬質合成ゴムであり、硬度はショアＡ硬さ（ＳｈｏｒｅＡ）７５、引張強さは１６０ｋｇ／ｃｍ²以上、最大伸長率は３００％以上である。 The material of the pad main body 41 of the rubber pad 40 is synthetic rubber, the hardness is Shore A hardness (Shore A) 50, the tensile strength is 200 kg / cm ² or more, and the maximum elongation is 500% or more. The material of the fixing rod 50 is hard synthetic rubber, the hardness is Shore A hardness (Shore A) 75, the tensile strength is 160 kg / cm ² or more, and the maximum elongation is 300% or more.

本発明の実施形態における取替可能なゴムパッド４０の設計と排水機能をもつゴム製舗装板２０の組合せ実施形態では、前記ゴムパッド４０は２本のレールＡの内側にあり、車両がレールＡを通過していないときは、前記ゴムパッド４０の上面４２とゴム製舗装板２０の上面２２がほぼ平らであるが、軌道車両がレールＡを通過するときは、軌道車両の車輪Ｃの輪縁がゴムパッド４０のパッド本体４１の上面４２を圧迫して通過する。前記空洞の緩衝室４４に弾性変形作用が生じるため、パッド本体４１の上面４２が一時的に下に凹み、車輪の通過後には元の状態に戻る。しかし、底面の硬質固定棒５０も硬質のゴム製舗装板２０と係合しているため、緩んで抜けることが起こりにくい。 In the embodiment of the rubber pad 40 having the design of the replaceable rubber pad 40 and the drainage function in the embodiment of the present invention, the rubber pad 40 is inside the two rails A, and the vehicle passes through the rails A. When not, the upper surface 42 of the rubber pad 40 and the upper surface 22 of the rubber pavement plate 20 are substantially flat. However, when the track vehicle passes the rail A, the ring edge of the wheel C of the track vehicle is the rubber pad 40. The upper surface 42 of the pad main body 41 is pressed and passed. Since an elastic deformation action is generated in the hollow buffer chamber 44, the upper surface 42 of the pad main body 41 is temporarily recessed downward, and returns to its original state after passing through the wheel. However, since the hard fixing bar 50 on the bottom surface is also engaged with the hard rubber pavement plate 20, it is difficult to loosen and come off.
