Description

この考案は、コンクリート製のケーブルトラフなどコンクリート製トラフに関するものである。 This invention relates to a concrete trough such as a concrete cable trough.

従来一般的に、コンクリート製のトラフは鉄道などの軌道脇において鉄道用の信号、通信、電力等のケーブルを前記軌道（例えば線路）に沿って収容敷設し、日光、大気、風雨および鼠害等から保護するものとして使用されている。 Conventionally, concrete troughs generally lay cables, signals, communications, electric power, etc. for railways along the tracks (eg, tracks) alongside the tracks such as railways, so that sunlight, the atmosphere, wind and rain, damage, etc. Used to protect from

しかしながら従来のトラフは例えば特開平６−２８４５４３号公報に記載されているように、そのトラフ本体が単に断面凹状をなしており、またトラフ本体を構成する両側壁の長手方向一端面に連結用凹部が設けられ、かつ連結する他方のトラフ本体を構成する両側壁の長手方向他端面に前記凹部に嵌り込む凸部が設けられ、その各々の凹部と凸部を嵌り込ませてただ単に連結敷設するものとしていた。
特開平６−２８４５４３号公報 However, the conventional trough, for example, as described in JP-A-6-284543, the trough body simply has a concave cross section, and the connecting recesses are formed on one end surface in the longitudinal direction of both side walls constituting the trough body. And a convex portion that fits into the concave portion is provided on the other longitudinal end surface of both side walls that constitute the other trough body to be coupled, and the respective concave portion and convex portion are fitted into each other to simply lay the connection. I was supposed to.
JP-A-6-284543

しかしながら、前述したような従来のトラフでは連結時に上下方向のみならず左右方向に連結ずれを生じさせないため、必ずトラフの幅方向下端部隅角部にＬ型の補助鋼を添設して補強しなければならず作業が面倒になってしまうと共に、コストアップの原因ともなっていた。   However, the conventional trough as described above does not cause misalignment not only in the vertical direction but also in the horizontal direction at the time of connection. Therefore, L-shaped auxiliary steel is always added to the lower corner of the trough in the width direction for reinforcement. This has been a tedious task and increased costs.

また、トラフの連結敷設に際しても、トラフ長手方向両側壁の両端面に設けた凹部と凸部をただ単に突き合わせ、嵌め込んで連結するものであり、長期間の使用において連結部にずれが生じてしまうとの課題があった。
かくして本考案は前記従来の課題に対処すべく創案されたものであり、トラフの幅方向下端部隅角部にＬ型の補助鋼を添設して補強する必要がないため作業が面倒になってしまうと共に、コストアップの原因ともなることなく、スムーズな施行で連結時に上下方向のみならず左右方向に連結ずれを生じないトラフを提供することを目的とするものである。
In addition, when connecting and laying troughs, the concave and convex portions provided on both end faces of the trough longitudinal side walls are simply abutted and fitted and connected. There was a problem with it.
Thus, the present invention has been devised to cope with the above-described conventional problems, and it is not necessary to reinforce the trough by adding L-shaped auxiliary steel to the lower end corner in the width direction, which makes the work troublesome. In addition, the present invention aims to provide a trough that does not cause an increase in cost, and that does not cause a shift in connection in the horizontal direction as well as the vertical direction during connection with smooth enforcement.

本考案によるコンクリート製トラフであれば、トラフの幅方向下端部隅角部にＬ型の補助鋼を添設して補強する必要がないため作業が面倒になってしまうことがないと共に、コストアップの原因ともなることなく、スムーズな施工でもって連結時にはトラフ本体の上下方向のみならず左右方向（幅方向）にも連結ずれを生じないコンクリート製トラフを提供できるとの優れた効果を奏する。
With the concrete trough according to the present invention, there is no need to reinforce the trough by adding an L-shaped auxiliary steel to the bottom corner of the trough in the width direction. In other words, it is possible to provide a concrete trough that does not cause misalignment not only in the vertical direction of the trough body but also in the horizontal direction (width direction) at the time of connection with smooth construction.

以下、この考案を図に示す実施例に基づいて説明する。
本考案によるトラフ１は、断面凹状をなすトラフ本体２と、該トラフ本体２の上部開口を塞ぐ蓋部材３とを有して構成されている。 Hereinafter, the present invention will be described based on embodiments shown in the drawings.
A trough 1 according to the present invention includes a trough body 2 having a concave cross section and a lid member 3 that closes an upper opening of the trough body 2.

蓋部材３は、図２に示すように、幅方向両側下端部に切り欠き１４，１４が設けられ、この切り欠き１４，１４の間は下側に凸設する肉厚部１５として構成されている。よって、トラフ本体２の上部開口へ前記肉厚部１５が嵌り込み、ガタツキのない蓋部材３として機能するものとなる。また、図２から理解されるように、当該蓋部材３の表面は面取りされており、外観上の美観が考慮されていると共に、トラフ破損防止、及び作業者などへの危険防止が図られている。   As shown in FIG. 2, the lid member 3 is provided with notches 14 and 14 at the lower end portions on both sides in the width direction, and a gap 15 between the notches 14 and 14 is configured as a thick portion 15 projecting downward. Yes. Therefore, the thick portion 15 is fitted into the upper opening of the trough body 2 and functions as the lid member 3 without backlash. In addition, as can be understood from FIG. 2, the surface of the lid member 3 is chamfered, the appearance is considered, and the trough is prevented from being damaged and the danger to workers is prevented. Yes.

ここで、前記トラフ本体２の長手方向一方側の右側壁端面４には、上下方向の連結ずれを解消する凹状連結ずれ解消部５が形成されている。
また、長手方向一方側の左側壁端面６には、前記凹状連結ずれ解消部５に嵌り合う形状に形成された凸状連結ずれ解消部７が設けられている。
さらに、図から理解されるように、前記トラフ本体２の長手方向他方側の右側壁端面８には、やはり上下方向の連結ずれを解消すべく、前記凹状連結ずれ解消部５に嵌り合う凸状連結ずれ解消部７が形成され、かつ長手方向他方側の左側壁端面９には、前記凸状連結ずれ解消部７に嵌り合う形状に形成された凹状連結ずれ解消部５が設けられている。 Here, the right side wall end face 4 on one side in the longitudinal direction of the trough body 2 is formed with a concave connection deviation canceling portion 5 for eliminating the vertical connection deviation.
Further, the left side wall end surface 6 on one side in the longitudinal direction is provided with a convex connection deviation canceling portion 7 formed in a shape that fits the concave connection deviation cancellation portion 5.
Further, as can be understood from the figure, the right side wall end surface 8 on the other side in the longitudinal direction of the trough body 2 has a convex shape that fits into the concave connection deviation canceling portion 5 in order to eliminate the vertical connection deviation. A connection displacement canceling portion 7 is formed, and a concave connection displacement canceling portion 5 formed in a shape that fits the convex connection displacement canceling portion 7 is provided on the left side wall end surface 9 on the other side in the longitudinal direction.

なお、図に示す実施例では、トラフ本体２における長手方向一方側の右側壁端面４に、上下方向の連結ずれを解消する凹状連結ずれ解消部５が形成され、左側壁端面６に前記凹状連結ずれ解消部５に嵌り合う形状に形成された凸状連結ずれ解消部７が設けられ、長手方向他方側の右側壁端面８に、前記凹状連結ずれ解消部５に嵌り合う凸状連結ずれ解消部７が形成され、かつ長手方向他方側の左側壁端面９に、前記凸状連結ずれ解消部７に嵌り合う形状に形成された凹状連結ずれ解消部５が設けられているが、各々凹状連結ずれ解消部及び凸状連結ずれ解消部を右、左逆側の側壁端面に設けても構わないものである。 In the embodiment shown in the figure, the right side wall end surface 4 on one side in the longitudinal direction of the trough body 2 is formed with a concave connection deviation canceling portion 5 that eliminates vertical connection deviation, and the left side wall end surface 6 has the concave connection. A convex connection displacement canceling portion 7 formed in a shape that fits the displacement cancellation portion 5 is provided, and a convex connection displacement cancellation portion that fits the concave connection displacement cancellation portion 5 on the right side wall end surface 8 on the other side in the longitudinal direction. 7 and a concave connection displacement canceling portion 5 formed in a shape that fits the convex connection displacement canceling portion 7 is provided on the left side wall end surface 9 on the other side in the longitudinal direction. The elimination part and the convex connection deviation elimination part may be provided on the right and left side wall end faces.

次に、前記トラフ本体２の長手方向一方側の底壁端面１０には、左右方向、換言すればトラフ本体２の幅方向に対する連結ずれを解消すべく幅方向に凹凸形状を連続して形成した第１凹凸状連結ずれ解消部１１が形成されている。
そして、トラフ本体２の長手方向他方側の底壁端面１２には、前記第１凹凸状連結ずれ解消部１１に嵌り合うべく幅方向に凸凹形状を連続して形成した第２凹凸状連結ずれ解消部１３が形成されている。 Next, the bottom wall end surface 10 on one side in the longitudinal direction of the trough body 2 is continuously formed with a concavo-convex shape in the lateral direction, in other words, in the width direction so as to eliminate the connection shift in the width direction of the trough body 2. A first uneven connection displacement canceling portion 11 is formed.
Then, the bottom uneven end 12 of the trough body 2 on the other side in the longitudinal direction is formed by continuously forming a concave and convex shape in the width direction so as to fit the first concave and convex connection displacement canceling portion 11. A portion 13 is formed.

ここで、前述した凹状連結ずれ解消部５及び当該凹状連結ずれ解消部５に嵌り合う形状に形成された凸状連結ずれ解消部７の形状は、図１から理解されるように、底辺側から先端側に向かって窄められた略台形形状に構成するのが好ましいものである。
さらに、前記第１凹凸状連結ずれ解消部１１及び第２凹凸状連結ずれ解消部１３における凹凸形状についても、底辺側から先端側に向かって窄められた略台形形状に構成するのが好ましいものである。
このような形状に形成することにより、連結時に嵌め合うポイントが大きくなり、スムーズかつ容易に連結操作できるものとなる。 Here, as can be understood from FIG. 1, the shape of the concave connection deviation eliminating portion 5 and the shape of the convex connection deviation elimination portion 7 formed to fit the concave connection deviation elimination portion 5 are as follows. It is preferable to form a substantially trapezoidal shape that is narrowed toward the tip side.
Furthermore, it is preferable that the concave and convex shapes in the first concave and convex connection displacement canceling portion 11 and the second concave and convex connection displacement canceling portion 13 are also formed in a substantially trapezoidal shape constricted from the bottom side toward the distal end side. It is.
By forming into such a shape, the point which fits at the time of a connection becomes large, and a connection operation can be performed smoothly and easily.

また凹状連結ずれ解消部５と凸状連結ずれ解消部７とを嵌り込ませるという簡単な連結作業によって、相隣る連結すべきトラフ本体３、３を上下方向における連結ずれを全く生じさせることなく連結出来るものとなる。
さらに、前記第１凹凸状連結ずれ解消部１１及び当該第１凹凸状連結ずれ解消部１１に嵌り合う第２凹凸状連結ずれ解消部１３の凹凸形状についてもトラフ本体２の幅方向に連続する凹凸形状とし、かつその連続した凹凸形状を、底辺側から先端側に向かって窄められた略台形形状に構成するものとする。
このような形状とすることにより、相隣る連結すべきトラフ本体３、３の左右方向、換言すれば幅方向における連結ずれを全く生じさせることなく連結出来るものとなるのである。
Moreover, the trough bodies 3 and 3 to be connected next to each other are not caused at all in the vertical direction by a simple connecting operation of fitting the concave connection deviation eliminating portion 5 and the convex connection deviation eliminating portion 7 together. It can be connected.
Further, the concave and convex shapes of the first concave and convex connection displacement canceling portion 11 and the concave and convex shape of the second concave and convex connection and disconnection canceling portion 13 that fits in the first concave and convex connection and disconnection canceling portion 11 are also continuous in the width direction of the trough body 2. It is assumed that the shape and the continuous uneven shape is a substantially trapezoidal shape constricted from the bottom side toward the tip side.
By adopting such a shape, the trough bodies 3 and 3 to be connected next to each other can be connected without causing any connection displacement in the left-right direction, in other words, the width direction.
