Description

本発明は一般的にはトラフ構造体及びそれを利用した敷設方法に関するものであり、具体的には合成樹脂製のトラフ構造体とその敷設方法に関するものである。   The present invention generally relates to a trough structure and a laying method using the same, and more specifically to a trough structure made of synthetic resin and a laying method thereof.

断面U字状又はコの字状のトラフ本体と、当該トラフ本体を塞ぐ蓋とからなる合成樹脂製のケーブルトラフ等のトラフ構造体は、成形性がよく軽量で敷設の作業性が優れている反面、軽量であることと相互の摩擦が小さいことから閉蓋状態におけるトラフ本体と蓋とが滑り易い。   A trough structure such as a cable trough made of synthetic resin composed of a trough body having a U-shaped or U-shaped cross section and a lid that closes the trough body has a good moldability and is lightweight and has an excellent workability for laying. On the other hand, the trough body and the lid are easily slipped in the closed state due to the light weight and the small mutual friction.

合成樹脂製のトラフ構造体では、トラフ本体に対して蓋を一部落し蓋形状に成形したもの(後記特許文献1)や、トラフ本体と蓋との嵌合部を長さ方向に沿うあり溝部とこれに嵌合するあり部とで構成したもの(後記特許文献2,3)などが提案されている。   In the trough structure made of synthetic resin, a part of the lid is dropped with respect to the trough main body and formed into a lid shape (Patent Document 1 described later), and a fitting portion between the trough main body and the lid is provided with a groove portion along the length direction. The thing (after-mentioned patent document 2, 3) etc. which comprised with the part with which this fits is proposed.

前記従来のトラフ構造体は、トラフ本体に対する蓋の滑りが幅方向では阻止されるほか、後者は蓋がトラフ本体から上方に向かって外れるのは阻止されるが、いずれも長さ方向には滑り易い。
勿論トラフ本体に対して蓋を両側部において止め具で押えて止める(後記特許文献3)と滑り難くなるが、蓋を本体に対して止め具で止めるのはトラフの敷設工程では後の工程である。また、蓋を止め具等で止めないで敷設するように設計される場合もある。
このように、敷設工程における敷設状態ではトラフ本体と蓋は止め具などで固定されず、種々の作業のため作業員がトラフ本体を塞いだだけの蓋の上を歩行し、あるいは作業道具の接触などにより蓋がトラフ本体に対して長さ方向に滑るため作業の安全上好ましくなかった。
さらに、通常の閉蓋状態で車両に積載して運送されるので、運送中の振動により蓋がトラフ本体に対して長さ方向に滑り、荷崩れが生じるおそれや荷崩れに到らないまでも荷姿を悪くすることがあった。

The conventional trough structure prevents sliding of the lid with respect to the trough body in the width direction, and the latter prevents the lid from coming off from the trough body, but both slide in the length direction. easy.
Of course, it is difficult to slip when the lid is pressed against the trough body with stoppers on both sides (Patent Document 3 below), but the lid is stopped against the body with the stopper in the trough laying process in a later step. is there. In some cases, the lid is laid without being stopped by a stopper or the like.
In this way, in the laying state in the laying process, the trough body and the lid are not fixed with a stopper or the like, and the worker walks on the lid that just closed the trough body for various work, or contact with the work tool For example, the lid slides in the length direction with respect to the trough body.
Furthermore, since it is transported while being loaded on the vehicle in a normal closed state, the lid slides in the length direction with respect to the trough body due to vibration during transportation, and there is no possibility that the load collapses or the load collapses. There was a case where the packing was bad.

本発明に係るトラフ構造体は前記課題を解決するため次のように構成したものである。
すなわち、本発明に係るトラフ構造体は、合成樹脂製のトラフ本体1と、当該トラフ本体1の上端開口を塞ぐ合成樹脂製の蓋2とを備え、前記トラフ本体1の側壁10の上端面と当該上端面と対応する前記蓋2の下面との一方には穴状凹部30が、他方には閉蓋時に当該穴状凹部30内に収まる凸部31がそれぞれ形成され、前記穴状凹部30と凸部31は、前記トラフ本体1に対する蓋2の長さ方向と幅方向のずれを阻止するずれ止め手段3を構成していることを最も主要な特徴としている。
前記トラフ構造体状は、U字状断面又はコ字状断面若しくはこれらの断面形状に近い形で、トラフ本体1の上端開口を塞ぐ合成樹脂製の蓋2を有しているものであれば、本発明の効果をさまたげない限り多少の断面形状の相違は許容される。前記穴状凹部30と凸部31は、トラフ構造体の長さ方向に沿って細長状に形成するのが好ましい。
The trough structure according to the present invention is configured as follows in order to solve the above problems.
That is, the trough structure according to the present invention includes a trough body 1 made of synthetic resin and a lid 2 made of synthetic resin that closes an upper end opening of the trough body 1, and an upper end surface of the side wall 10 of the trough body 1 A hole-shaped recess 30 is formed on one of the upper end surface and the lower surface of the lid 2 corresponding to the upper end surface, and a protrusion 31 that fits in the hole-shaped recess 30 when the lid is closed is formed on the other. The most prominent feature of the convex portion 31 is that it constitutes an anti-displacement means 3 for preventing the displacement of the lid 2 in the length direction and the width direction with respect to the trough body 1.
If the trough structure has a U-shaped cross-section or a U-shaped cross-section or a shape close to these cross-sectional shapes and has a lid 2 made of synthetic resin that closes the upper end opening of the trough body 1, As long as the effects of the present invention are not impaired, a slight difference in cross-sectional shape is allowed. The hole-shaped concave portion 30 and the convex portion 31 are preferably formed in an elongated shape along the length direction of the trough structure.

本発明に係るトラフ構造体の敷設方法は、前記課題を解決するため次のように構成したものである。すなわち、前記トラフ本体1を蓋体2で塞いだ前記本発明に係るトラフ構造体を敷設する際に、直前に敷設されたトラフ構造体の後端部へ次に敷設すべきトラフ構造体の前端部を連結し又は当接しながらトラフ構造体を順次敷設する工程を含むことを最も主要な特徴としている。
前記トラフ構造体を断面ほぼ角樋状のトラフ橋4の上に沿って敷設する場合には、トラフ本体1の底部両側にフランジ部12を形成したトラフ構造体を使用し、当該トラフ構造体を前記フランジ部の部分においてアンカーボルト等を用いたボルトナット等によってトラフ橋4へ固定することができる。

プラスチック製品の廃材などを利用した合成樹脂製のトラフ本体1には、同様な材質の蓋2が両側部において当接状態で塞がれるように構成されている。
トラフ本体1の両側壁10,10には、外側面に所定の間隔で高さ方向(垂直方向)に沿う多数の縦リブ11が形成され、これらの縦リブ11を含む側壁10の上端面は閉蓋状態において蓋2の裏側の両側部寄り下面と当接する。
A trough body 1 made of synthetic resin using waste material of a plastic product or the like is configured such that a lid 2 made of the same material is closed in contact with both sides.
On both side walls 10 and 10 of the trough body 1, a large number of vertical ribs 11 are formed on the outer surface along the height direction (vertical direction) at predetermined intervals, and the upper end surface of the side wall 10 including these vertical ribs 11 is In the closed state, it comes into contact with the lower surface near the both sides on the back side of the lid 2.

図4のトラフ本体1長手方向の両端部分を除く他の縦リブ11は、下方に延びるにしたがって徐々に幅が広がり、底部方向に近付いた部分から側方へ先下がり状に傾斜し、それらの下端部は底部両側に張り出した長さ方向に沿うフランジ部12と連続している。
このように、前記縦リブ11は下方に延びるにしたがって徐々に幅が広がる方が好ましいが、必ずしもは下方に延びるにしたがって徐々に幅が広がっている必要はなく、また底部のフランジ12はなくてもよい。
図4及び図7のように、閉蓋状態では底部のフランジ部12を含むトラフ本体1の幅と蓋2の幅とはほぼ等しくなるように成形されている。
The other vertical ribs 11 except for both end portions in the longitudinal direction of the trough body 1 in FIG. 4 gradually increase in width as they extend downward, and incline downwardly from the portion approaching the bottom direction. The lower end portion is continuous with the flange portion 12 extending along the length direction projecting on both sides of the bottom portion.
As described above, it is preferable that the width of the vertical rib 11 gradually increases as it extends downward. However, it is not always necessary that the width of the vertical rib 11 gradually increases as it extends downward, and there is no bottom flange 12. Also good.
As shown in FIGS. 4 and 7, in the closed state, the width of the trough body 1 including the bottom flange portion 12 and the width of the lid 2 are formed to be substantially equal.

トラフ本体1の一端部(図1及び図3の右端)には断面内形を拡大した雌状連結部13が形成され、他端部には前記雌状連結部13の内部へ納まる程度に外形を縮小した雄状連結部14が形成されている。
雌状連結部13の両内壁面端部には抜け止め突起13aが縦方向へ形成され、他方雄状連結部14の両外壁面端部には前記抜け止め突起13aと対応する係止突起14aがそれぞれ縦方向に沿って形成されている。
トラフ本体1の前記雌状連結部13へ隣接する位置及び雄状連結部14へ隣接する位置には、両側壁10,10の外側面へ後述するバックル金具6の固定部を取り付けるための取付ベース15が棚状に形成されている。
16は上げ底状の底面へ幅方向に沿って平行に多数形成された底部補強リブであり、一部の底部補強リブ16の中央部には、トラフ本体1を必要に応じて設置ベースへボルトナットで固定するための短環状のボルト案内部17が形成されている。
The trough body 1 is formed with a female coupling portion 13 having an enlarged cross-sectional shape at one end (the right end in FIGS. 1 and 3), and the other end has an outer shape so that the female coupling portion 13 can be accommodated inside the female coupling portion 13. The male connection part 14 which reduced is formed.
Retaining protrusions 13a are formed in the vertical direction on both inner wall end portions of the female connecting portion 13, and locking protrusions 14a corresponding to the retaining protrusion 13a are formed on both outer wall surface ends of the male connecting portion 14. Are formed along the vertical direction.
A mounting base for attaching a fixing portion of a buckle fitting 6 to be described later to the outer side surfaces of both side walls 10 and 10 at a position adjacent to the female connection portion 13 and a position adjacent to the male connection portion 14 of the trough body 1. 15 is formed in a shelf shape.
A number of bottom reinforcing ribs 16 are formed in parallel to the bottom surface of the raised bottom in the width direction. At the center of some bottom reinforcing ribs 16, the trough body 1 is attached to the installation base as needed by bolts and nuts. A short annular bolt guide portion 17 is formed for fixing with the screw.

蓋2は、厚肉で全体がほぼ板状に成形されており、一端部が前記トラフ本体1の雌状連結部13の内部を除く位置から、他端部が雄状連結部14の端部からやや突出する程度の長さを有している。
蓋2の一端部(図2,図3の右端部)へ断面外形を縮小した短い内側ラップ部20が形成されている。一方他端部には、前記内側ラップ部20と対応する外側ラップ部21が形成されている。蓋2をトラフ本体1へ被せた図3の閉蓋状態では、この外側ラップ部21の先端部の内側ラップ部20の長さに相当する長さ分がトラフ本体1の他端部から突出する。
蓋2の両端部分における前記トラフ本体1の取付ベース15と対応する位置には、両側部上面から側面にわたって平面視ほぼコ字状ないしU字状に連続するように、後述するバックル金具の金属棒からなる押え部が案内される案内溝22が形成されている。
The lid 2 is thick and is generally shaped like a plate. One end of the lid 2 is located at a position other than the inside of the female coupling portion 13 of the trough body 1 and the other end is the end of the male coupling portion 14. It has a length that slightly protrudes from.
A short inner wrap 20 having a reduced cross-sectional outer shape is formed at one end of the lid 2 (the right end in FIGS. 2 and 3). On the other hand, an outer wrap portion 21 corresponding to the inner wrap portion 20 is formed at the other end portion. In the closed state of FIG. 3 in which the lid 2 is put on the trough body 1, a length corresponding to the length of the inner wrap portion 20 at the distal end portion of the outer wrap portion 21 protrudes from the other end portion of the trough body 1. .
A metal bar of a buckle fitting, which will be described later, is provided at positions corresponding to the mounting base 15 of the trough body 1 at both ends of the lid 2 so as to be substantially U-shaped or U-shaped in plan view from the upper surface to the side surface of both side portions. A guide groove 22 is formed for guiding the presser portion made of

トラフ本体1の両側壁10の上端面と蓋2との当接領域の長さ方向両端部寄り位置には、側壁10の上端面へ長さ方向に沿って各凸部31が四箇所に形成され、閉蓋時に当該各凸部31がそれぞれ収まるように蓋2へ各穴状凹部30が形成されている。これらの各穴状凹部30とそれらに対応する凸部31とは、トラフ本体1に対して蓋2の長さ方向と幅方向へのずれを阻止するずれ止め手段3を構成している。   At positions closer to both ends in the length direction of the contact area between the upper end surfaces of the side walls 10 and the lid 2 of the trough body 1, four convex portions 31 are formed along the length direction on the upper end surfaces of the side walls 10. In addition, each hole-like recess 30 is formed in the lid 2 so that each of the projections 31 can be accommodated when the lid is closed. Each of the hole-shaped concave portions 30 and the corresponding convex portions 31 constitute a displacement preventing means 3 that prevents the trough body 1 from shifting in the length direction and the width direction of the lid 2.

この実施形態において、前記ずれ止め手段3は前記のようにトラフ本体1の両側部寄りにかつ長さ方向両端部寄りに位置しており、長さ方向一端部寄りに位置している各ずれ止め手段3と他端部寄りに位置している各ずれ止め手段3とは、前記トラフ本体1の長さ方向の中央部を基準とした場合の位置が非対称であるか、また、それらの形状又は寸法が異なっている。
したがって、前記蓋2の長さ方向一端部が前記トラフ本体1の長さ方向に対して一定方向に位置している場合にのみ、当該蓋2を前記トラフ本体1へ正常に閉蓋することができる。すなわち、蓋2の閉蓋姿勢の正逆を間違えることがない。
In this embodiment, the displacement preventing means 3 is located near both sides of the trough body 1 and near both ends in the longitudinal direction as described above, and each displacement stopper located near one end in the length direction. The position of the means 3 and each of the displacement preventing means 3 located near the other end is asymmetric with respect to the central portion of the trough body 1 in the length direction, and their shape or The dimensions are different.
Therefore, the lid 2 can be normally closed to the trough body 1 only when one end in the length direction of the lid 2 is positioned in a certain direction with respect to the length direction of the trough body 1. it can. That is, there is no mistake in whether the lid 2 is closed or not.

長さ方向に沿って4個所形成された各凸部31は平面視においてトラフ本体1の長さ方向に沿い細長状を呈するほぼ長方形であるか、あるいは二箇所のみを細長状のほぼ長方形とし、残りの二箇所を円錐台状の形状とすることができる。
各穴状凹部30は各凸部31と相似形状又は各穴状凹部30のテーパ角度を少し小さくして、各穴状凹部30の底部と凸部31のクリアランスが徐々に減少するような形状で、当該凸部31の体積よりもやや大きい容積を有する。各凸部31の断面形状は急傾斜(70〜88°)の錐台形状であって、基端方向から先端方向へ徐々に断面積が減少する状態に形成されている。
前記傾斜角度は必要に応じて、70〜88°の間の角度に適宜設計できるが、蓋を滑らして被せる時の被せ易さの他、トラフ上を点検等の目的で検査員が歩く場合の蓋のすべりなどを考慮すると、その傾斜角度は75°〜85°、80°〜85°であるのがさらに望ましい。
Each of the convex portions 31 formed at four locations along the length direction is a substantially rectangular shape having an elongated shape along the length direction of the trough body 1 in a plan view, or only two portions are formed into a substantially rectangular shape, The remaining two locations can be in the shape of a truncated cone.
Each hole-like recess 30 has a shape similar to each protrusion 31 or a shape in which the taper angle of each hole-like recess 30 is slightly reduced so that the clearance between the bottom of each hole-like recess 30 and the protrusion 31 gradually decreases. The volume of the convex portion 31 is slightly larger. The cross-sectional shape of each convex part 31 is a frustum shape with a steep slope (70 to 88 °), and is formed in a state in which the cross-sectional area gradually decreases from the proximal direction to the distal direction.
The tilt angle can be appropriately designed to be between 70 ° and 88 ° as necessary. In addition to the ease of covering when sliding the lid, the inspector walks on the trough for inspection purposes. Considering the sliding of the lid, the inclination angle is more preferably 75 ° to 85 ° and 80 ° to 85 °.

また、各穴状凹部30と凸部31のトラフ側壁両端部に対する傾斜角度は、必ずしも同一でなくても良く、穴状凹部30の傾斜角度が凸部31の傾斜角度より小さいほうが、穴状凹部30の奥部、すなわち穴状内底部における凸部31先端とのクリアランランスCL(閉蓋状態で穴状凹部30へ凸部31が挿入されている部分の横断面又は縦断面において、穴状凹部30の内周面と凸部31の内底面との隙間を言う。)を小さくできることから、閉蓋時に芯合わせ効果を持たせることができる。
また、穴状凹部30に傾斜角度を持たせ、凸部31はトラフ側壁上端面に対して直角にすることもできる。
したがって、閉蓋時に各凸部31がそれぞれ対応する穴状凹部30へ両者の中心が一致する状態で案内されたと仮定した場合、両者間には幅方向(図5の左右方向)及び長さ方向(図6の左右向)の両側へそれぞれ所定のクリアランスCLが形成される。
また、各凸部31の上端と対応する穴状凹部30の内底面(この実施形態では天井面)とは接触しても良いが、接触しない方が好ましい。その理由は、各凸部31の上端と対応する穴状凹部30の内底面が接触する場合は、樹脂成形時の寸法ばらつきにより、蓋が浮き上がる場合があるからである。
In addition, the inclination angles of the hole-shaped concave portions 30 and the convex portions 31 with respect to both ends of the trough side wall are not necessarily the same, and the inclination angle of the hole-shaped concave portions 30 is smaller than the inclination angle of the convex portions 31. Clearance lance CL with the back of 30, that is, the tip of the convex portion 31 at the inner bottom of the hole (in the horizontal or vertical section of the portion where the convex portion 31 is inserted into the hole-shaped concave portion 30 in the closed state) The gap between the inner peripheral surface of 30 and the inner bottom surface of the convex portion 31) can be reduced, so that a centering effect can be provided when the lid is closed.
In addition, the hole-shaped concave portion 30 can be inclined, and the convex portion 31 can be perpendicular to the upper end surface of the trough sidewall.
Therefore, when it is assumed that each convex portion 31 is guided to the corresponding hole-shaped concave portion 30 when the lid is closed in a state where both centers coincide with each other, the width direction (the left-right direction in FIG. 5) and the length direction therebetween. Predetermined clearances CL are formed on both sides (left and right in FIG. 6).
Moreover, although it may contact with the inner bottom face (ceiling surface in this embodiment) of the hole-shaped recessed part 30 corresponding to the upper end of each convex part 31, it is preferable that it does not contact. The reason is that when the upper end of each convex portion 31 and the inner bottom surface of the corresponding hole-shaped concave portion 30 are in contact, the lid may float due to dimensional variations during resin molding.

幅方向のクリアランスCL(図5)及び長さ方向のクリアランスCL(図6)は、閉蓋時の各穴状凹部30とそれに対応する凸部31との位置合わせ(芯合わせ)に手間取らないようにするためと、トラフ本体1及び蓋2における材質の収縮の影響を避けるために形成される。   The clearance CL in the width direction (FIG. 5) and the clearance CL in the length direction (FIG. 6) do not take time to align (center alignment) the hole-shaped concave portions 30 and the corresponding convex portions 31 when the lid is closed. In order to do so, the trough body 1 and the lid 2 are formed in order to avoid the influence of material shrinkage.

クリアランスの量は合成樹脂材料の材質にもよるが、前記両方の目的を達成するためには、穴状凹部30の先端と凸部31の底部の幅方向の両側(図の幅方向両側)の合計が2mmから5mmで、かつそれぞれ凸部31の幅の5〜30%であるのが好ましく、10〜25%であるのがさらに好ましい。長さ方向の両側(図の長さ方向両側)のクリアランスは、合計4mmから10mmで、且つ凸部31の長さ2〜10%であるの好ましく、5〜8%程度であるのがさらに好ましい。
孔状凹部30の底部と凸部31の先端のクリアランスが徐々に減少するような形状になっているので、穴状凹部30の底部と凸部31の先端の幅方向クリアランスは、適宜設計することが可能であるが、その合計は1mmから2mmで、長さ方向クリアランスの合計は、2mmから4mm程度とすることが望ましい。このようにすれば、閉蓋後の蓋のすべりを防止できる。
Although the amount of clearance depends on the material of the synthetic resin material, in order to achieve both of the above-mentioned purposes, the width direction both sides of the tip of the hole-like recess 30 and the bottom of the projection 31 (both sides in the width direction in the figure). The total is 2 to 5 mm, and preferably 5 to 30% of the width of the convex portion 31 and more preferably 10 to 25%. Clearances on both sides in the length direction (both sides in the figure) are 4 to 10 mm in total, and the length of the protrusion 31 is preferably 2 to 10%, more preferably about 5 to 8%. .
Since the clearance between the bottom of the hole-shaped concave portion 30 and the tip of the convex portion 31 is gradually reduced, the widthwise clearance between the bottom of the hole-shaped concave portion 30 and the tip of the convex portion 31 should be designed as appropriate. However, the total is preferably 1 mm to 2 mm, and the total length clearance is preferably about 2 mm to 4 mm. In this way, it is possible to prevent the lid from slipping after the lid is closed.

この実施形態のトラフ構造体は、図3〜図6で示すようにトラフ本体1に対して蓋2を被せると、各穴状凹部30へそれらに対応する凸部31が収まるように挿入され、蓋姿勢の正逆を間違えることはない。
この状態において、蓋2の一端(図3の右端)部における内側ラップ部20の先端は、トラフ本体1における雌状連結部13内の内側端とほぼ一致する状態に位置し、蓋2の他端部における外側ラップ部21の先端は、前記内側ラップ部20の長さにほぼ相当する長さ分がトラフ本体1の雄状連結部14の端部から突出する。
As shown in FIGS. 3 to 6, the trough structure of this embodiment is inserted into each hole-like recess 30 so that the corresponding protrusions 31 are accommodated when the lid 2 is put on the trough body 1, There is no mistake in the position of the lid.
In this state, the tip of the inner wrap portion 20 at one end (right end in FIG. 3) of the lid 2 is positioned so as to substantially coincide with the inner end in the female coupling portion 13 in the trough body 1. The tip of the outer wrap portion 21 at the end protrudes from the end of the male coupling portion 14 of the trough body 1 by a length substantially corresponding to the length of the inner wrap portion 20.

前記実施形態のトラフ構造体によれば、閉蓋状態でトラフ本体1に対する蓋2の幅方向のみならず長さ方向の滑りも防止することができるから、運送や倉庫への保管その他の取扱いの際に障害が少なくかつ便利であり、さらに静電気の帯電も少なくなる。
前記ずれ止め手段3である各穴状凹部30と各対応する凸部31との間には、前記のようなクリアランスCLがある。したがって、前記ずれ止め手段3はトラフ本体1に対する蓋2の滑りを抑制し、穴状凹部30に対する凸部31の位置合わせないし芯合わせ作用により、穴状凹部30に対する凸部31の挿入が容易になり、円滑な閉蓋作業を阻害することはない。
According to the trough structure of the above embodiment, it is possible to prevent not only the width direction but also the length direction slip of the lid 2 with respect to the trough body 1 in the closed state. It is less troublesome and convenient, and also reduces static charge.
There is a clearance CL as described above between each hole-like concave portion 30 which is the displacement preventing means 3 and each corresponding convex portion 31. Therefore, the slip prevention means 3 suppresses the sliding of the lid 2 with respect to the trough body 1, and the convex portion 31 can be easily inserted into the hole-shaped concave portion 30 by the alignment or centering action of the convex portion 31 with respect to the hole-shaped concave portion 30. Therefore, the smooth closing operation is not hindered.

前記ずれ止め手段3におけるクリアランスCLは、閉蓋状態において前記凸部31の先端部外周面と前記穴状凹部30の奥部内周面とのクリアランスCLよりも、前記凸部31の基端部外周面と前記穴状凹部30の開口端部内周面とのクリアランスCLを大きく設定する(図5,6において、上端部のクリアランスよりも下端部のクリアランスを大きく設定する)のが好ましい。そして、幅方向のクリアランスCLよりも長さ方向のクリアランスCLを大きく設定するのが好ましい。このようにクリアランス設定にすることにより、トラフ本体1を蓋2で塞いだ場合に、凹部30と凸部31との芯合わせ効果がよりよく発揮される。   The clearance CL in the displacement preventing means 3 is larger than the clearance CL between the outer peripheral surface of the distal end portion of the convex portion 31 and the inner peripheral surface of the deep portion of the hole-shaped concave portion 30 in the closed state. The clearance CL between the surface and the inner peripheral surface of the opening end of the hole-shaped recess 30 is preferably set large (in FIGS. 5 and 6, the clearance at the lower end is set larger than the clearance at the upper end). The clearance CL in the length direction is preferably set larger than the clearance CL in the width direction. By setting the clearance in this way, when the trough body 1 is closed with the lid 2, the effect of aligning the recesses 30 and the protrusions 31 is more effectively exhibited.

また、前記のように閉蓋状態で各穴状凹部30とそれらに対応する各凸部31の高さ方向に向けてのクリアランスを徐々に小さくすることにより、外気温の変化や日照による合成樹脂材料の熱変形による種々の弊害(収縮による変形や歪みの発生や膨張による変形、再開蓋や再閉蓋困難等)を防止することができる。
例えば後述のように、敷設状態でバックル金具6等を用いて蓋2をトラフ本体1へ押圧固定した場合でも、蓋2のずれの衝撃は当該バックル金具6には及ばないので、バックル金具6の損耗が防止され、その長寿命化に役立つ。
In addition, by gradually reducing the clearance in the height direction of each hole-like concave portion 30 and the corresponding convex portion 31 in the closed state as described above, the synthetic resin due to changes in outside air temperature or sunlight Various adverse effects due to thermal deformation of the material (deformation due to shrinkage, distortion or deformation due to expansion, difficulty in reopening and reclosing, etc.) can be prevented.
For example, as will be described later, even when the lid 2 is pressed and fixed to the trough body 1 using the buckle fitting 6 or the like in the laid state, the impact of the displacement of the lid 2 does not reach the buckle fitting 6. Wear is prevented and it is useful for extending its life.

前記第1実施形態において、前記凸部31は長さ方向へ連続して形成されている。例えば図6の二点鎖線で示すように各凸部31の長さ方向の中央部へ所定長さの切欠状部31bを形成し、両端部の二つの部分を対としても実施できる。このように形成すると、合成樹脂材料の使用量がより小さくなる。
各凸部31は前記のように急峻な傾斜の角錐台形状に形成されているが、前記のようなクリアランスが形成されていれば、ほぼ角柱状であっても実施することができる。また、各凸部31は四角柱状又は四角錐台形状、円柱状又は円錐台形状及び楕円柱ないしその錐台形状その他これらに類する形状であってもよい。
In the first embodiment, the convex portion 31 is formed continuously in the length direction. For example, as shown by a two-dot chain line in FIG. 6, a notch 31b having a predetermined length may be formed at the center in the length direction of each convex portion 31, and two portions at both ends may be paired. When formed in this way, the amount of the synthetic resin material used becomes smaller.
Each of the convex portions 31 is formed in a truncated pyramid shape having a steep slope as described above. However, if the clearance as described above is formed, it can be implemented even in a substantially prismatic shape. Each convex portion 31 may have a quadrangular prism shape or a truncated pyramid shape, a cylindrical shape or a truncated cone shape, an elliptical column shape, a truncated cone shape, or the like.

閉蓋作業時の案内機能を持たせるには、凸部31を四角錐台形状や楕円柱又は楕円錐形状、あるいは四角錐台形状の短片を半円又は円弧の一部と置き換えた長円柱形状又は長円錐形状を複合した形状とする方がよい。
このようにすると、蓋2をトラフ本体1の長手方向に対して斜めにして、トラフ本体1の凸部31の一部に蓋の孔状凹部30の一部を合わせ、蓋を長手方向に沿って滑らせて閉蓋することができるので便利である。
In order to provide a guide function at the time of the closing operation, the convex portion 31 has a truncated pyramid shape, an elliptical column or an elliptical cone shape, or a long cylindrical shape in which a short piece of the truncated pyramid shape is replaced with a semicircle or a part of an arc. Or it is better to make it the shape which compounded the long cone shape.
In this way, the lid 2 is inclined with respect to the longitudinal direction of the trough main body 1, a part of the hole-shaped concave portion 30 of the lid is aligned with a part of the convex portion 31 of the trough main body 1, and the lid is moved along the longitudinal direction. It is convenient because it can be slid and closed.

凸部31上下端の平均長さは、蓋を滑らせて閉蓋するためには、滑り長さを考えると、少なくともトラフ本体1の長さ方向に40mm〜150mm程度である。40mm以下であると短すぎてスムーズに滑らせることができないし、これ以上長いと、すべり距離が大きく無駄が多い。望ましくは、80mm〜120mm程度であることがさらに好ましい。 また、穴状凹部30上下端のトラフ本体長さ方向の平均長さは、上記の凸部31上下端の平均長さにその両側に設けるべきクリアランスを加えた長さに設定すればよい。   The average length of the upper and lower ends of the convex portion 31 is about 40 mm to 150 mm at least in the length direction of the trough body 1 in consideration of the sliding length in order to slide the lid and close the lid. If it is 40 mm or less, it is too short to slide smoothly, and if it is longer than this, the sliding distance is large and wasteful. Desirably, the thickness is more preferably about 80 mm to 120 mm. Moreover, what is necessary is just to set the average length of the trough main body length direction of the upper and lower ends of the hole-shaped recessed part 30 to the length which added the clearance which should be provided in the both sides to the average length of said convex part 31 upper and lower ends.

第1実施形態のトラフ構造体では、蓋2のずれ止め手段3である穴状凹部30とそれに対応する凸部31は、トラフ本体1の長さ方向に沿う細長状であるので、トラフ構造体の少なくとも一箇所に設ければ前記と同様な効果を発揮する。
ずれ止め手段3を複数設ける場合において、閉蓋時の蓋姿勢の正逆間違いを防止するためには、前記のようにそれらの位置を非対称としたりそれらを異なる寸法にしたりすることに代えて、形状の異なる各ずれ止め手段3を設けることができる。
In the trough structure of the first embodiment, the hole-shaped recess 30 which is the displacement preventing means 3 of the lid 2 and the corresponding protrusion 31 are elongated along the length direction of the trough body 1, so the trough structure If provided in at least one place, the same effect as described above is exhibited.
In the case of providing a plurality of displacement preventing means 3, in order to prevent the forward / reverse error of the lid posture at the time of closing, instead of making the positions asymmetric or making them different dimensions as described above, Each shift preventing means 3 having a different shape can be provided.

次に前記第1実施形態のトラフ構造体を、トラフ橋を用いて敷設する方法について図3,図4を参照しながら説明する。
4は支柱5の上に固定されたトラフ橋であり、それぞれの垂直部40a,41aがトラフ本体1の幅よりやや広い程度の間隔で相対するように、水平な補強板42を介してアングルベース40,41の水平部を重ねる。この状態で支柱5相互を連結している連結ベース44の上に連結板42を介して連結するとともに、これらを支柱5へボルトナットなどで固定してほぼ角樋状のトラフ橋4を順次構築する。
Next, a method of laying the trough structure of the first embodiment using a trough bridge will be described with reference to FIGS.
Reference numeral 4 denotes a trough bridge fixed on the column 5, and an angle base is provided via a horizontal reinforcing plate 42 so that the vertical portions 40 a and 41 a face each other at a slightly larger interval than the width of the trough body 1. The horizontal portions 40 and 41 are overlapped. In this state, the columns 5 are connected to the connection base 44 that connects the columns 5 with each other via the connection plate 42, and these are fixed to the columns 5 with bolts and nuts, etc., so that the substantially square trough-shaped trough bridge 4 is sequentially constructed. To do.

トラフ橋4の内底部へ浅い溝状の上げ底受板43を敷設し、その上にトラフ構造体を順次並べて敷設する。
例えば、図3で示すようにトラフ本体1を蓋2で閉蓋し、これらのトラフ構造体をトラフ橋4の上に敷設する。その要領は、あらかじめトラフ橋4の両側寄り位置にアンカーボルト(図示しない)を取り付け、当該ボルトの軸を受板43の挿通孔(図示しない)に通して上方へ突出させておく。
A shallow groove-shaped raised bottom receiving plate 43 is laid on the inner bottom of the trough bridge 4, and the trough structures are sequentially laid on the raised bottom receiving plate 43.
For example, as shown in FIG. 3, the trough body 1 is closed with a lid 2, and these trough structures are laid on the trough bridge 4. The procedure is that anchor bolts (not shown) are attached in advance to positions on both sides of the trough bridge 4, and the shafts of the bolts are projected upward through insertion holes (not shown) of the receiving plate 43.

閉蓋状態のトラフ構造体をトラフ橋4上の溝状の上げ底受板43の上に長さ方向に沿って載置し、このように直前に載置したトラフ構造体の雌状連結部13が位置する部分へ次のトラフ構造体の雄状連結部14を上方から案内収容する要領で連結し、同時にこれを上げ底受板43上に載置する。このとき、直前に載置されたトラフ構造体における蓋2の内側ラップ20の上に次のトラフ構造体における蓋の外側ラップ部21が重なった状態となり、蓋2相互の上面はほぼ面一となる。
以上の要領でトラフ構造体を順次連結しながら敷設し、その後、トラフ構造体における底部両側のフランジ部12の挿通孔(図示しない)へ前記ボルトの軸を通してナットを締め付け、トラフ橋4へ固定する。あるいは、敷設しながら順次トラフ構造体をトラフ橋4上にボルトナットで固定してゆく。
この実施形態のトラフ構造体の敷設方法によれば、蓋2がトラフ本体1に対して幅方向にも長さ方向にもずれ止めされ、それらを一体として敷設することにより施工コストの大幅な削減が図られる。
また、種々の作業の際に作業員が蓋の上を安全に歩行することができるから、他の作業も容易になる。
The trough structure in the closed state is placed on the groove-like raised bottom receiving plate 43 on the trough bridge 4 along the length direction, and the female connecting portion 13 of the trough structure placed immediately before in this way. The male connecting portion 14 of the next trough structure is connected to the portion where the is located in the manner of guiding and accommodating from above, and at the same time, it is raised and placed on the bottom receiving plate 43. At this time, the outer wrap portion 21 of the lid of the next trough structure overlaps the inner wrap 20 of the lid 2 of the trough structure placed immediately before, and the upper surfaces of the lids 2 are substantially flush with each other. Become.
The trough structure is laid while being sequentially connected in the manner described above, and then the nut is tightened through the shaft of the bolt to the insertion hole (not shown) of the flange portion 12 on both sides of the bottom portion of the trough structure and fixed to the trough bridge 4. . Alternatively, the trough structure is sequentially fixed on the trough bridge 4 with bolts and nuts while being laid.
According to the laying method of the trough structure of this embodiment, the lid 2 is prevented from slipping in the width direction and the length direction with respect to the trough body 1, and the construction cost is greatly reduced by laying them together. Is planned.
Further, since the worker can safely walk on the lid during various operations, other operations are facilitated.

前記のように敷設した後に、例えば図7,8で示すように、各トラフ本体1の長さ方向両端部分において蓋2をトラフ本体1へバックル金具6により押え付けて固定する。
バックル金具6は、図9で示すように所定形状に曲げ加工された金属棒からなる押え部60と、この押え部60の曲げ端部を保持してトラフ本体1の取付ベース15へ固定する固定部61とから構成されている。
After laying as described above, for example, as shown in FIGS. 7 and 8, the lid 2 is pressed and fixed to the trough body 1 by the buckle fitting 6 at both ends in the longitudinal direction of each trough body 1.
As shown in FIG. 9, the buckle fitting 6 has a holding part 60 made of a metal rod bent into a predetermined shape, and a fixing for holding the bent end part of the holding part 60 and fixing it to the mounting base 15 of the trough body 1. Part 61.

押え部60は金属棒(この実施形態では丸棒)を蓋2の案内溝22と適合するように平面視コ字状ないしU字状に曲げ加工した主部60aと、主部60aの両端部をほぼ鉛直に曲げ下げた脚部60b,60bと、各脚部60bの端部をほぼ直角で相対向状に曲げた各被保持部60c,60cとから構成されている。   The holding portion 60 includes a main portion 60a obtained by bending a metal bar (in this embodiment, a round bar) into a U shape or a U shape in plan view so as to fit the guide groove 22 of the lid 2, and both end portions of the main portion 60a. The leg portions 60b, 60b are bent substantially vertically, and the held portions 60c, 60c are formed by bending the end portions of the leg portions 60b substantially perpendicular to each other.

固定部61は、例えば板ばねやステンレス板のような弾性金属板を、前記取付ベース15を挟持に適するように断面横コ字状ないし横U字状に曲げ加工した挟持部61aと、当該挟持部61aの上側板を折り返し状にカールさせたカール部61bと、当該カール部61bの折り返し部端部を断面ほぼ円形状に曲げ加工した保持部61cとから構成されている。
保持部61cには前記押え部60の各被保持部60cが、それぞれ差し込み状に保持されている。また、挟持部61aの下側板には弾性を強化するため内側(上側)に向けて傾斜状に切り起こした弾性片61dが形成されている。カール部61bの両端部には、短いスリット状の切り欠き61eが形成されている。
The fixing portion 61 includes, for example, a clamping portion 61a obtained by bending an elastic metal plate such as a leaf spring or a stainless steel plate into a U-shaped or U-shaped cross section so that the mounting base 15 is suitable for clamping. The curling portion 61b is formed by curling the upper plate of the portion 61a in a folded shape, and the holding portion 61c is formed by bending the end portion of the folded portion of the curled portion 61b into a substantially circular shape.
Each held portion 60c of the pressing portion 60 is held in the holding portion 61c in an insertion shape. Further, an elastic piece 61d that is cut and raised in an inward (upper) direction is formed on the lower plate of the sandwiching portion 61a in order to enhance elasticity. Short slit-shaped notches 61e are formed at both ends of the curled portion 61b.

前記のように構成されたバックル金具6は、押え部60を蓋2の案内溝22へ案内し、固定部61の挟持部61aによりトラフ本体1の取付ベース15を側部から押付けて挟ませる要領で取り付け、蓋2をトラフ本体1へ押付け状に固定する。
バックル金具6により蓋2をトラフ本体1へ固定する作業は、トラフ構造体の敷設前に行なっても、あるいはトラフ構造体を敷設する手順にしたがって敷設しながら順次行なっても差し支えない。
バックル金具6は、蓋2をトラフ本体1へ固定することができる形態であれば他の形態のものでも使用することができるほか、敷設場所の環境によっては、バックル金具等により蓋2をトラフ本体1へ固定しない場合でも実施することができる。
The buckle fitting 6 configured as described above guides the holding portion 60 to the guide groove 22 of the lid 2 and presses the mounting base 15 of the trough body 1 from the side by the holding portion 61a of the fixing portion 61 so as to be pinched. The lid 2 is fixed to the trough body 1 by pressing.
The operation of fixing the lid 2 to the trough body 1 with the buckle fitting 6 may be performed before laying the trough structure or sequentially while laying according to the procedure for laying the trough structure.
The buckle fitting 6 can be used in other forms as long as the lid 2 can be fixed to the trough body 1. Depending on the environment of the laying place, the lid 2 is attached to the trough body by a buckle fitting or the like. Even if it is not fixed to 1, it can be carried out.

敷設環境の条件によっては、トラフ本体1および蓋2をともにラップ部を有しない構造とし、閉蓋状態のトラフ構造体の相互の端部を当接させて敷設する構造とすることにより、トラフ橋やコンクリート等の敷設基礎上に載置するだけで現場敷設する場合もある。
このようにトラフ構造体の端部相互を当接させて敷設する場合には、前後の各トラフ構造体の突合わせが円滑にできるように、トラフ本体当接部断面の肉厚を厚くしたり、トラフ本体1底部の前後に切り欠きとこれに嵌合する突起を設けることにより、より安定的に敷設するかとができる。
また、トラフ構造体を閉蓋状態で現場に輸送し、当該閉蓋状態のままで敷設すると、敷設工事が著しく簡素化され、施工コストの大幅削減が可能になる。
Depending on the conditions of the laying environment, both the trough body 1 and the lid 2 have a structure that does not have a wrap portion, and a structure in which the ends of the trough structure in the closed state are brought into contact with each other to construct a trough bridge. In some cases, it is laid on the ground simply by placing it on a foundation such as concrete or concrete.
When laying the trough structure in such a manner that the ends of the trough structure are brought into contact with each other, the thickness of the cross section of the trough body abutting portion is increased so that the front and rear trough structures can be smoothly abutted. It is possible to lay more stably by providing a notch and a protrusion that fits into the front and rear of the bottom of the trough body 1.
Further, when the trough structure is transported to the site in a closed state and laid in the closed state, the laying work is remarkably simplified and the construction cost can be greatly reduced.

第2実施形態
穴状凹部30は、トラフ本体1の取り扱い中に当該凹部30内へ塵芥等が溜まるのを防止するためには、第1実施形態のトラフ構造体のように蓋2へ形成するのが好ましいが、機能的には、例えば図10のように、穴状凹部30をトラフ本体1の側壁10の上端面へ形成し、凸部31を蓋2へ形成しても差し支えない。
Second Embodiment The hole-shaped recess 30 is formed on the lid 2 like the trough structure of the first embodiment in order to prevent dust and the like from accumulating in the recess 30 during handling of the trough body 1. However, functionally, for example, as shown in FIG. 10, the hole-shaped concave portion 30 may be formed on the upper end surface of the side wall 10 of the trough body 1 and the convex portion 31 may be formed on the lid 2.

第3実施形態
図11及び図12はトラフ構造体の第3実施形態を示す部分拡大断面図であり、穴状凹部30への凸部31の挿入案内を円滑にするための変形形態を示している。
トラフ本体1における側壁10の上端面に形成されている凸部31には、先端部(頂部)に先端方向に向かって徐々に縮小する傾斜状(図11)又は断面円弧状(図12)の挿入ガイド部31aが形成されており、当該凸部31は基部から前記挿入ガイド31aに向かう各部の断面体積がほぼ等しくなるように構成されている。
他方、蓋2側に形成されている穴状凹部30には、開口部分に開口端方向に向かって徐々に拡大する傾斜状(図11)又は断面円弧状(図12)の受入れガイド部30aが形成されており、当該穴状凹部30は奥部から前記受入れガイド部30aに向かう各部の断面容積がほぼ等しくなるように構成されている。
このように構成することにより、凸部31の凹部30への挿入案内(閉蓋作業)を円滑にすることができる。
Third Embodiment FIGS. 11 and 12 are partially enlarged cross-sectional views showing a third embodiment of the trough structure, showing a modified form for smooth insertion guide of the convex portion 31 into the hole-shaped concave portion 30. FIG. Yes.
The convex portion 31 formed on the upper end surface of the side wall 10 of the trough body 1 has an inclined shape (FIG. 11) or a circular arc shape (FIG. 12) that gradually decreases toward the distal end (top) toward the distal end. An insertion guide portion 31a is formed, and the convex portion 31 is configured such that the cross-sectional volumes of the respective portions from the base portion toward the insertion guide 31a are substantially equal.
On the other hand, in the hole-like recess 30 formed on the lid 2 side, an acceptance guide portion 30a having an inclined shape (FIG. 11) or a circular arc shape (FIG. 12) gradually expanding toward the opening end direction at the opening portion. The hole-shaped recess 30 is formed so that the cross-sectional volume of each part from the inner part toward the receiving guide part 30a is substantially equal.
By comprising in this way, the insertion guide (lid closing operation | work) to the recessed part 30 of the convex part 31 can be made smooth.

第4実施形態
図13の(e)図はトラフ構造体の第4実施形態を示す蓋の部分底面図、同(f)図は(e)図の矢印C−Cに沿う部分拡大断面図である。
この実施形態は、穴状凹部30への凸部31の挿入案内をさらに円滑にするための変形形態であり、第1実施形態のトラフ構造体とほぼ同様に、蓋2には図示されていない対応する凸部が収まる穴状凹部30が形成されている。
蓋2には、穴状凹部30の長さ方向の両端部(一端部でも実施できる)と連続するように、当該穴状凹部30の長さとほぼ等しい長さで長さ方向に沿う状態に当該穴状凹部30よりも浅いガイド溝30bが形成されている。このガイド溝30bの幅は対応する凹部30の幅とほぼ等しい。
Fourth Embodiment FIG. 13 (e) is a partial bottom view of a lid showing a fourth embodiment of the trough structure, and FIG. 13 (f) is a partially enlarged sectional view taken along arrow CC in FIG. 13 (e). is there.
This embodiment is a modified form for further smoothing the insertion guide of the convex portion 31 into the hole-shaped concave portion 30, and is not shown in the lid 2 in substantially the same manner as the trough structure of the first embodiment. A hole-like recess 30 is formed in which the corresponding protrusion is accommodated.
The lid 2 has a length that is substantially equal to the length of the hole-shaped recess 30 along the length direction so as to be continuous with both ends of the hole-shaped recess 30 in the length direction (can also be implemented at one end). A guide groove 30 b shallower than the hole-shaped recess 30 is formed. The width of the guide groove 30b is substantially equal to the width of the corresponding recess 30.

閉蓋時に蓋2をトラフ本体1の上に長さ方向に沿って載せると、ガイド溝30bへ対応する凸部31の先端部が案内されるので、この状態で蓋2をその長さがトラフ本体1の長さとほぼ適合する方向へ滑らせると、当該凸部31は対応する凹部30へ円滑に挿入される。
この実施形態において、ガイド溝30bの長さは対応する凹部30の長さ以上であるのが好ましいが、蓋2をトラフ本体1の上に載せるときに両者の長さ方向の位置関係に大差を生じることはほとんどないので、前記ガイド溝30bの長さは特に限定されない。また、前記ガイド溝30bは蓋2の長さ方向へ連続して形成されていても差し支えない。
When the lid 2 is placed on the trough body 1 along the length direction when the lid is closed, the tip end portion of the convex portion 31 corresponding to the guide groove 30b is guided. When sliding in a direction substantially matching the length of the main body 1, the convex portion 31 is smoothly inserted into the corresponding concave portion 30.
In this embodiment, the length of the guide groove 30b is preferably equal to or longer than the length of the corresponding recess 30.
