Description

この発明はオープントップコンテナ、詳しくはトレーラに搭載され、産業廃棄物、例えばスクラップを搬送するオープントップコンテナに関する。 The present invention relates to an open top container, and more particularly to an open top container mounted on a trailer for carrying industrial waste such as scrap.

廃自動車や建築廃材などを破砕処理するスクラップ加工処理工場からは、多量のスクラップが排出される。これらのスクラップを工場外へ搬出する際には、グラップルまたはマグネット付きのラフテレーンクレーンやスクラップローダーを利用し、スクラップヤードから廃棄物搬送用のトレーラのオープントップコンテナに移載される。
従来のオープントップコンテナ（以下、コンテナとも言う）は、例えば特許文献１に示すように、それぞれ床、前壁、後壁、左右一対の側壁を有し、天井部分が開口された箱体で構成されている。 A large amount of scrap is discharged from a scrap processing plant that crushes scrapped automobiles and construction waste materials. When these scraps are carried out of the factory, they are transferred from the scrap yard to the open-top container of the trailer for waste transport, using a rough terrain crane with a grapple or a magnet or a scrap loader.
BACKGROUND ART A conventional open top container (hereinafter, also referred to as a container) includes a floor, a front wall, a rear wall, a pair of left and right side walls, and a box body having an open ceiling portion, as shown in Patent Document 1, for example. Has been done.

このうちの床は、それぞれが普通鋼製のフロントレール、リアレールおよび左右一対のサイドレールからなる前後方向に長い矩形状の床枠に、前後方向に所定ピッチで例えば複数本の角形鋼管製の横根太がそれぞれ平行に溶接されるとともに、各横根太の下面に、左右方向へ平行に離間した状態で複数本の角形鋼管製の縦根太がそれぞれ溶接され、さらに床枠の上に耐摩耗鋼板製で前後方向に長い矩形状の床板が溶接されたものである。なお、各横根太の下面に各縦根太を溶接する際には、三角形状の多数の溶接片材を介して溶接される。 The floor among them is a rectangular floor frame that is long in the front-rear direction and consists of a front rail, a rear rail, and a pair of left and right side rails made of ordinary steel. The thick beams are welded in parallel, and the bottoms of the horizontal joists are welded together with vertical joists made of rectangular steel pipes that are spaced parallel to each other in the left-right direction. Is a rectangular floor plate that is welded in the front-rear direction. In addition, when welding each vertical joist to the lower surface of each horizontal joist, it welds through many welding piece materials of a triangular shape.

また、前壁は、それぞれが普通鋼製の下方配置の前記フロントレール、上方配置のフロント梁、左右一対のフロント側柱からなる略正方形の前枠に、耐摩耗鋼板製の前板が溶接され、前板の外面に、格子状の前板用補強板が溶接されたものである。
さらに、後壁は、それぞれが普通鋼製である下方配置の前記リアレール、上方配置のリア梁、左右一対のフロント側柱からなる略正方形の前枠に、耐摩耗鋼板製の後板が溶接され、後板の外面に、格子状の後板用補強板が溶接されたものである。
さらにまた、左右一対の側壁は、それぞれが普通鋼製のフロントサイドレール、リアサイドレール、ロアサイドレールおよびアッパサイドレールからなる前後方向に長い矩形状の左右一対の側枠に、耐摩耗鋼板からなる左右一対の側板が溶接されて、各側板の外面に、複数の縦長な傾斜補強板（側板用補強板）が、前後方向に所定ピッチで平行に溶接されたものである。 In addition, the front wall is welded with a front plate made of wear-resistant steel plate on a substantially square front frame composed of the above-mentioned front rails made of ordinary steel and arranged downward, the front beams arranged above, and a pair of left and right front side columns. A grid-like reinforcing plate for the front plate is welded to the outer surface of the front plate.
Further, the rear wall of the rear plate made of wear-resistant steel plate is welded to the substantially square front frame composed of the rear rails which are made of ordinary steel and are arranged downward, the rear beams which are arranged upward, and the pair of left and right front side columns. A grid-like reinforcing plate for a rear plate is welded to the outer surface of the rear plate.
Furthermore, the pair of left and right side walls are made of wear-resistant steel plates in a pair of left and right rectangular side frames that are long in the front-rear direction and are made of plain steel, including front side rails, rear side rails, lower side rails, and upper side rails. A pair of left and right side plates are welded, and a plurality of vertically long inclined reinforcing plates (reinforcing plates for side plates) are welded to the outer surface of each side plate in parallel in the front-rear direction at a predetermined pitch.

特許第５８９８７６０号公報Patent No. 5898760

しかしながら、従来のオープントップコンテナにあっては、このように床枠、多数本の横根太、縦根太、多数の溶接片材、前枠、後枠および各補強板が、それぞれ炭素含有量０．６ｗｔ％以下の比重が大きい普通鋼製であった。これにより、オープントップコンテナの重量が嵩張り、その分だけスクラップの積載量が減少していた。
また、このように床板を支持する角パイプ状の横根太と縦根太とが、上下に格子状に溶接されていたため、その分、コンテナの重心が高くなり、スクラップ輸送中のトレーラの走行安定性が低下していた。 However, in the conventional open top container, the floor frame, the multiple horizontal joists, the vertical joists, the multiple welding piece materials, the front frame, the rear frame, and the reinforcing plates each have a carbon content of 0. It was made of ordinary steel with a large specific gravity of 6 wt% or less. As a result, the weight of the open top container was increased, and the load of scrap was reduced accordingly.
Moreover, since the square pipe-shaped horizontal joists and vertical joists supporting the floorboard were welded in a grid pattern up and down in this way, the center of gravity of the container was increased by that amount, and the running stability of the trailer during scrap transportation was increased. Was falling.

さらに、上述した横根太、縦根太および各補強板等の素材としての普通鋼は、比較的軟らかい鋼である。その結果、コンテナでは、スクラップ全体を下向きに押圧しながら積載することから、床、前壁、後壁および左右一対の側壁の各中央部がスクラップにより外方へ向かって押されて膨み、塑性変形が生じ易かった。これらの床や壁の中央部の変形は、トレーラによるスクラップ搬送を長期間行うことで拡大し、その結果、各壁等の中央部の疲労による機械的強度も低下し、疲労破壊が発生していた。すなわち、これらの床や壁の中央部に微小なクラックが発生し、繰り返し応力を受けることで割れ目が徐々に大きくなっていた。 Further, the ordinary steel as a material of the lateral joists, the vertical joists, the respective reinforcing plates, etc. is a relatively soft steel. As a result, in the container, the entire scrap is loaded while being pressed downward, so that the central portions of the floor, front wall, rear wall, and the pair of left and right side walls are pushed outward by the scrap and expand, causing plasticity. Deformation was easy to occur. The deformation of the center of these floors and walls was enlarged by carrying scrap for a long time by a trailer.As a result, the mechanical strength due to fatigue of the center of each wall, etc. decreased and fatigue fracture occurred. .. That is, minute cracks were generated in the center of these floors and walls, and the cracks gradually increased due to repeated stress.

そこで、発明者は鋭意研究の結果、床板、前板、後板および左右一対の側板だけでなく、横根太、縦根太、前板用補強板、後板用補強板および傾斜補強板の各素材として、従来の普通鋼より高強度な耐摩耗鋼板を採用すれば、高強度化した分だけ材料の使用量を減らしてオープントップコンテナの軽量化が図れ、その分だけスクラップの積載量が増大するとともに、床、前壁、後壁および各側壁の疲労破壊を防止できることを知見した。しかも、従来のように横根太と縦根太とを上下２段に溶接するのではなく、横根太と縦根太とを互いに突き合わせ状態で（同一高さに配置して）溶接すれば、その分だけコンテナの重心が下がり、スクラップ輸送中の廃棄物搬送用のトレーラの走行安定性も高まることを知見することで、この発明を完成させた。 Therefore, as a result of earnest research, the inventor has found that not only floor boards, front boards, rear boards and a pair of left and right side boards, but also horizontal joists, vertical joists, front board reinforcing boards, rear board reinforcing boards, and inclined reinforcing board materials. As a result, if a wear-resistant steel plate with higher strength than that of conventional ordinary steel is adopted, the amount of material used will be reduced by the amount of increased strength and the weight of the open top container will be reduced, and the load of scrap will increase accordingly. At the same time, it was found that fatigue failure of the floor, front wall, rear wall and each side wall can be prevented. Moreover, instead of welding the horizontal joist and the vertical joist in upper and lower two stages as in the conventional case, if the horizontal joist and the vertical joist are welded in a state of being butted against each other (arranged at the same height), only that much The present invention has been completed by finding that the center of gravity of a container is lowered and the traveling stability of a trailer for transporting waste during scrap transportation is enhanced.

この発明は、コンテナの軽量化が図れてスクラップの積載量を増大可能で、コンテナの重心を下げてスクラップ輸送中のトレーラの走行安定性を高めることができ、さらには床、前壁、後壁および各側壁の疲労破壊を防止できるオープントップコンテナを提供することを目的としている。 This invention can reduce the weight of the container and increase the load of scrap, lower the center of gravity of the container and improve the traveling stability of the trailer during scrap transportation, and further can improve the floor, front wall, and rear wall. Another object of the present invention is to provide an open top container that can prevent fatigue damage on each side wall.

In an open top container that has a rear wall that welds plates and a pair of left and right side walls that weld side plate reinforcing plates to the outer surfaces of a pair of left and right side plates, respectively, and has a ceiling portion that opens and loads scrap into its internal space The floor plate, the front plate, the rear plate, and the pair of left and right side plates are each formed of an abrasion resistant steel plate having an elastic limit point of 1000 to 2000 N/mm 2 and a Brinell hardness of 300 to 700 HBW. , The same material, the horizontal joist, the vertical joist, the front plate reinforcing plate, the rear plate reinforcing plate and the left and right pair of side plate reinforcing plate, respectively, the horizontal joist and the vertical joist Is an open top container that is butt welded.

オープントップコンテナは、自走するトラクタ（牽引車）に連結された廃棄物搬送用のトレーラ（被牽引車）に搭載される。
スクラップの種類は限定されない。例えば、廃自動車や建築廃材などの破砕物を採用することができる。もちろん、オープントップコンテナによって輸送可能な積載物は限定されない。例えば、スクラップを除く他の産業廃棄物でもよい。
オープントップコンテナとは、床、前壁、後壁、左右一対の側壁を有し、天井部分が常時開口された金属製の箱体である。 The open top container is mounted on a trailer (a towed vehicle) for transporting waste, which is connected to a self-propelled tractor (a towed vehicle).
The type of scrap is not limited. For example, a crushed material such as an abandoned car or a construction waste can be adopted. Of course, the load that can be transported by the open top container is not limited. For example, other industrial wastes other than scrap may be used.
The open top container is a metal box body that has a floor, a front wall, a rear wall, and a pair of left and right side walls, and has a ceiling portion that is always open.

床は、床板の下面に、横根太と縦根太とを互いに突合せ状態で格子状に溶接したものである。
具体的には、隣接する横根太と縦根太とを溶接するとともに、これらの根太を床板の下面にそれぞれ溶接する。横根太と縦根太との断面形状は任意である。例えば、断面コの字状、断面矩形状、断面三角形状でもよい。
このように、横根太と縦根太とを突き合わせる（根太同士が同一高さ位置に設けられ一方の小口面を他方の側面に当接させている）ことで、従来のように横根太と縦根太とを上下２段に配したものに比べて、コンテナの高さが低下する。横根太および縦根太の本数は、一般的に複数である（左右一対の側板用補強板も同じ）。 The floor is formed by welding horizontal joists and vertical joists to the lower surface of the floor board in a lattice-like manner in abutting state.
Specifically, the adjacent horizontal joists and vertical joists are welded, and these joists are welded to the lower surface of the floorboard, respectively. The cross-sectional shapes of the horizontal joist and the vertical joist are arbitrary. For example, it may have a U-shaped cross section, a rectangular cross section, or a triangular cross section.
In this way, the horizontal joists and the vertical joists are abutted (the joists are provided at the same height position, and one fore edge is brought into contact with the other side), so that the lateral joists and the vertical joists can be made as in the conventional method. The height of the container is lower than that of the one in which the joists and the joists are arranged vertically. The number of horizontal joists and vertical joists is generally plural (the same applies to a pair of left and right reinforcing plates for side plates).

また、前壁は、前板の外面に前板用補強板を溶接したものである。前板用補強板の形状は任意である。例えば、格子状でもよい。
後壁は、後板の外面に後板用補強板を溶接したものである。後壁は、一対の側壁のうちの片方の側壁の後端に、上下方向に延びる回動軸を有したヒンジを介して開閉自在に設けても、そうでない密閉式（固着式）でもよい。後板用補強板の形状は任意である。例えば格子状でもよい。
左側壁は、左側板の外面に左側板用補強板を溶接したものであって、右側壁は、右側板の外面に右側板用補強板を溶接したものである。左側板用補強板および右側板用補強板の形状は任意である。例えば、それぞれ縦長なものでもよい。 The front wall is formed by welding a front plate reinforcing plate to the outer surface of the front plate. The shape of the reinforcing plate for the front plate is arbitrary. For example, it may have a lattice shape.
The rear wall is obtained by welding a rear plate reinforcing plate to the outer surface of the rear plate. The rear wall may be provided at the rear end of one side wall of the pair of side walls so as to be openable and closable via a hinge having a vertically extending rotating shaft, or may be a closed type (fixed type). The shape of the reinforcing plate for the rear plate is arbitrary. For example, it may be a lattice shape.
The left side wall is formed by welding the left side plate reinforcing plate to the outer surface of the left side plate, and the right side wall is formed by welding the right side plate reinforcing plate to the outer surface of the right side plate. The shapes of the left side reinforcing plate and the right side reinforcing plate are arbitrary. For example, each may be vertically long.

これらの床板、前板、後板および左右一対の側板と、横根太、縦根太、前板用補強板、後板用補強板および左右一対の側板用補強板とは、弾性限界点が１０００〜２０００Ｎ／ｍｍ２で、ブリネル硬さが３００〜７００ＨＢＷの耐磨耗鋼板によってそれぞれ形成されている。
耐摩耗鋼板は、鉄を主成分とし、これに炭素（Ｃ；０．２１重量％以上）、ケイ素（Ｓｉ：０．７０重量％以上）、マンガン（Ｍｎ：２．００重量％以上）、リン（Ｐ：０．０１５重量％以上）、イオウ（Ｓ：０．０１０重量％以上）、ニッケル（Ｎｉ：１．００重量％以上）、クロム（Ｃｒ：１２０重量％以上）、モリブデン（Ｍｏ：０．６０重量％以上）、ホウ素（Ｂ：０．００５重量％以上）が添加されたものである。 These floor plates, front plates, rear plates and a pair of left and right side plates and lateral joists, vertical joists, front plate reinforcing plates, rear plate reinforcing plates and left and right side plate reinforcing plates have elastic limit points of 1000 to It is formed of wear-resistant steel plates having a Brinell hardness of 300 to 700 HBW at 2000 N/mm 2 .
The wear-resistant steel plate is mainly composed of iron, and contains carbon (C; 0.21% by weight or more), silicon (Si: 0.70% by weight or more), manganese (Mn: 2.00% by weight or more), phosphorus. (P: 0.015 wt% or more), sulfur (S: 0.010 wt% or more), nickel (Ni: 1.00 wt% or more), chromium (Cr: 120 wt% or more), molybdenum (Mo:0 60% by weight or more) and boron (B: 0.005% by weight or more) are added.

耐摩耗鋼板の弾性限界点（降伏点）は、１０００〜２０００Ｎ／ｍｍ２である。１０００Ｎ／ｍｍ２未満では、弾性限界点が４００Ｎ／ｍｍ２程度の普通鋼と比べて、弾性変形能としてそれほど顕著な差異がない。また、２０００Ｎ／ｍｍ２を超えれば硬すぎて、コンテナにスクラップを投入した衝撃等で側壁が破損するおそれがある。特に、耐摩耗鋼板の弾性限界点（降伏点）は１０２５〜１４０５Ｎ／ｍｍ２が好ましい。
耐摩耗鋼板としては、例えば新日鐵住金社製のアブレックス（旧新日鐵社製のウェルハード、旧住友金属社製のスミハード）、ＪＦＥスチール社製のエバーハード、スウェーデンスチール社製のハルドックス（スウェーデン鋼）などを使用することができる。
耐摩耗鋼板の耐摩耗性は、ブリネル硬さで３００〜７００ＨＢＷである。３００ＨＢＷ未満では、１３０ＨＢＷ前後の普通鋼と比較して、耐摩耗性にそれほど顕著性がない。また、７００ＨＢＷを超えれば硬すぎて、コンテナにスクラップを投入した衝撃等で側壁が破損するおそれがある。特に、耐摩耗鋼板の耐摩耗性は、ブリネル硬さで４００〜５００ＨＢＷが好ましい。 The elastic limit point (yield point) of the wear-resistant steel plate is 1000 to 2000 N/mm 2 . When it is less than 1000 N/mm 2 , there is no significant difference in elastic deformability as compared with ordinary steel having an elastic limit of about 400 N/mm 2. Further, if it exceeds 2000 N/mm 2 , it is too hard, and the side wall may be damaged by the impact of throwing scrap into the container. In particular, the elastic limit point (yield point) of the wear resistant steel plate is preferably 1025 to 1405 N/mm 2 .
Examples of wear-resistant steel plates include ABREX made by Nippon Steel & Sumikin Co., Ltd. (Welhard made by Nippon Steel Co., Ltd., Sumihard made by Sumitomo Metal Co., Ltd.), Everhard made by JFE Steel, and Hardox made by Swedish Steel. (Swedish steel) can be used.
The wear resistance of the wear resistant steel plate is Brinell hardness of 300 to 700 HBW. When it is less than 300 HBW, the wear resistance is not so remarkable as compared with the ordinary steel around 130 HBW. Further, if it exceeds 700 HBW, it is too hard, and the side wall may be damaged by the impact of throwing scrap into the container. In particular, the wear resistance of the wear-resistant steel plate is preferably 400 to 500 HBW in terms of Brinell hardness.

請求項２に記載の発明は、前記横根太および前記縦根太は、それぞれ一対の平行な対峙板片の基端部同士を連結板片により連結した断面コの字状のもので、このうち、前記横根太は、開口を上に向けて前記床板の下面に溶接され、前記縦根太は、開口を横に向けて前記床板の下面と、隣接する前記横根太の突き合わせ面とにそれぞれ溶接されたものである請求項１に記載のオープントップコンテナである。 In the invention according to claim 2, the horizontal joists and the vertical joists are U-shaped in cross section in which the base end portions of a pair of parallel facing plate pieces are connected by a connecting plate piece. The horizontal joists are welded to the lower surface of the floorboard with the opening facing upwards, and the vertical joists are respectively welded to the lower surface of the floorboard with the opening facing laterally and the abutting surface of the adjacent lateral joists. The open top container according to claim 1, which is a container.

断面コの字状の横根太または縦根太とは、平行に離間した一対の細長い対峙板片の各基端を、連結板片によりそれぞれ直交状態で一体的に連結したチャンネル鋼材状のものである。
耐摩耗鋼板は硬いため、従来の横根太や縦根太のように、各辺が短い角パイプ状にプレス加工することは困難である。そのため、横根太および縦根太をプレス加工が可能なコの字状のものとした。 The horizontal joist or vertical joist having a U-shaped cross-section is a channel steel material in which the base ends of a pair of elongated facing plate pieces that are spaced in parallel are integrally connected in a perpendicular state by the connecting plate pieces. ..
Since the wear-resistant steel plate is hard, it is difficult to press it into a square pipe shape with each side having short sides like conventional horizontal joists and vertical joists. Therefore, the horizontal joists and vertical joists are U-shaped so that they can be pressed.

また、「横根太が、開口を上に向けて床板の下面に溶接されている」とは、横根太の各対峙板片の先端面が、それぞれ床板の下面に溶接されていることを意味する。
さらに、「縦根太が、開口を横に向けて床板の下面と、隣接する横根太の突き合わせ面とにそれぞれ溶接されている」とは、縦根太の上側の対峙板片の上面が床板の下面に溶接されているとともに、縦根太の連結板片の外面（縦根太側の突き合わせ面）が、隣接する横根太の突き合わせ面（対応する対峙板片の外面）に溶接されていることを意味する。 In addition, "horizontal joist is welded to the lower surface of the floorboard with the opening facing upward" means that the front end surface of each facing plate piece of lateral joist is welded to the lower surface of the floor board, respectively. ..
Furthermore, "the vertical joists are welded to the lower surface of the floorboard and the abutting surfaces of the adjacent lateral joists respectively with the openings facing horizontally" means that the upper surface of the facing plate piece on the upper side of the vertical joist is the lower surface of the floorboard. It means that the outer surface of the connecting plate piece of the vertical joist (the abutting surface on the vertical joist side) is welded to the adjacent abutting surface of the lateral joist (the outer surface of the corresponding facing plate piece). ..

横根太および縦根太の断面コの字状のサイズは任意である。ただし、横根太および縦根太は、コの字状の断面において、コの字の各対峙板片の部分の方をコの字の連結板片の部分より短くした方が好ましい。その理由は、耐摩耗鋼板が高硬度素材であることから、断面コの字の連結板片の部分（以下、コの字の両端部分）より断面コの字の各対峙板片の部分（以下、コの字の中間部分）を長くする加工が難しいためである。 The lateral joists and vertical joists have a U-shaped cross section of any size. However, regarding the horizontal joists and vertical joists, it is preferable that, in a U-shaped cross section, the portion of each U-shaped facing plate piece is shorter than the portion of the U-shaped connecting plate piece. The reason for this is that since the wear-resistant steel plate is a high hardness material, the portion of the connecting plate piece having a U-shaped section (hereinafter, both ends of the U-shaped section) is the portion of each facing plate piece having a U-shaped section (hereinafter This is because it is difficult to lengthen the middle part of the U-shape).

なお、横根太および縦根太は、それぞれ一対の平行な対峙板片の基端部同士を連結板片により連結した断面サイズが同一の断面コの字状のものとしてもよい。このようにすれば、開口を上に向けた横根太を、床枠（横根太と床枠とは高さが同じ）と床板の下面とに溶接し、また開口を横に向けた縦根太を、床板の下面と、隣接する横根太の突き合わせ面とにそれぞれ溶接した際に、各横根太の隣接する縦根太との突合せ部分において、横根太の連結板片の下面と地面との間にそれぞれ隙間が現出する。
そのため、仮に雨天時にコンテナの床下に雨水が浸入しても、雨水はこれらの隙間を通って床下の外へ流れ出る。また、このように通気性が良いため、床下に雨水がいくらか溜まっても乾燥し易い。これにより、雨水による床下部分の錆の発生を防止することができる。さらには、このように床下の通気性が高いことから、夏季のコンテナ内の温度上昇を抑えることもできる。 The horizontal joists and the vertical joists may have a U-shaped cross-section with the same cross-sectional size in which the base end portions of a pair of parallel facing plate pieces are connected by a connecting plate piece. By doing this, the horizontal joist with the opening facing up is welded to the floor frame (the horizontal joist and the floor frame have the same height) and the bottom surface of the floorboard, and the vertical joist with the opening facing sideways. , When the bottom surface of the floorboard and the abutting surface of the adjacent horizontal joists are respectively welded, at the abutting portion with the adjacent vertical joists of each lateral joist, between the lower surface of the connecting board piece of the lateral joists and the ground, respectively. A gap appears.
Therefore, even if rainwater enters under the floor of the container in the case of rain, the rainwater flows out through the gaps to the outside of the floor. Further, since the air permeability is good as described above, even if some rainwater is accumulated under the floor, it is easy to dry. As a result, it is possible to prevent rusting of the underfloor portion due to rainwater. Further, since the air permeability under the floor is high, it is possible to suppress the temperature rise in the container in the summer.

請求項１に記載の発明によれば、オープントップコンテナにおいて、床を構成する床板、横根太および縦根太と、前壁を構成する前板および前板用補強板と、後壁を構成する後板および後板用補強板と、左右一対の側壁を構成する各側板および対応する各側板用補強板との素材として、従来の普通鋼より高強度な耐摩耗鋼板を採用したことで材料の使用量が減少し、オープントップコンテナの軽量化が図れて、その分だけスクラップの積載量を増大させることができるとともに、床、前壁、後壁および各側壁の疲労破壊を防止することができる。 According to the invention as set forth in claim 1, in the open top container, a floor plate, a horizontal joist and a vertical joist that constitute a floor, a front plate and a front plate reinforcing plate that configure a front wall, and a rear wall that configures a rear wall. Use of materials by using wear-resistant steel plates with higher strength than conventional plain steel as the material for the reinforcing plate for the plate and the rear plate, each side plate that constitutes the pair of left and right side walls, and the corresponding reinforcing plate for each side plate The amount can be reduced, the weight of the open top container can be reduced, and the load of scrap can be increased correspondingly, and fatigue failure of the floor, front wall, rear wall and each side wall can be prevented.

すなわち、コンテナに多量のスクラップを積み込んだ場合には、床、前壁、後壁および左右一対の側壁の各中央部が多量のスクラップにより内方から押されて膨らもうとする。しかしながら、これらは、普通鋼より硬い耐摩耗鋼板からなるため、床および各壁の中央部の変形は抑制される。しかも、耐摩耗鋼板は普通鋼に比べて弾性限界点が高い。そのため、搬送先でスクラップを荷降ろしすれば、床および各壁への応力が取り除かれ、これらは塑性変形することなく、元の平坦な床や各壁に復元する。その結果、各壁等が多量のスクラップ投入による繰り返し応力を受けても、これらの中央部の機械的強度はほとんど低下せず、床、前壁、後壁および各側壁の疲労破壊が抑制される。
また、従来のように横根太と縦根太とを上下２段に溶接するのではなく、横根太と縦根太とを突き合わせ状態で溶接したため、その分、コンテナの高さが低くなってコンテナの重心が下がり、スクラップ輸送中のトレーラの走行安定性が高まる。 That is, when a large amount of scrap is loaded in the container, the central portions of the floor, the front wall, the rear wall, and the pair of left and right side walls are pushed from the inside by the large amount of scrap and try to expand. However, since these are made of wear-resistant steel plates that are harder than ordinary steel, deformation of the floor and the center of each wall is suppressed. Moreover, the wear-resistant steel plate has a higher elastic limit point than the ordinary steel. Therefore, when the scrap is unloaded at the destination, the stress on the floor and each wall is removed, and these are restored to the original flat floor and each wall without being plastically deformed. As a result, even if each wall is subjected to repeated stress due to a large amount of scrap input, the mechanical strength of these central parts does not decrease, and fatigue failure of the floor, front wall, rear wall and each side wall is suppressed. ..
Further, instead of welding the horizontal joist and the vertical joist in upper and lower two steps as in the conventional method, the horizontal joist and the vertical joist are welded in a butt state, so that the height of the container is lowered accordingly and the center of gravity of the container is lowered. Lowers the running stability of the trailer during scrap transportation.

特に、請求項２に記載のオープントップコンテナによれば、横根太および縦根太を断面コの字状をした耐摩耗鋼板からそれぞれ形成するようにした。これにより、横根太と縦根太とを例えば１本の断面コの字状の耐摩耗鋼板から切り分けることもでき、オープントップコンテナの部品点数を低減することができる。
また、従来のように不安定な直角三角形状の多数の溶接片材を介して、横根太と縦根太とを溶接する場合に比べて、部品点数がさらに低減するとともに溶接が容易となる。 Particularly, according to the open top container of the second aspect, the horizontal joists and the vertical joists are formed of wear-resistant steel plates each having a U-shaped cross section. Thereby, the horizontal joist and the vertical joist can be cut from, for example, one wear-resistant steel plate having a U-shaped cross section, and the number of parts of the open top container can be reduced.
Further, the number of parts is further reduced and welding is facilitated as compared with the conventional case where a horizontal joist and a vertical joist are welded through a large number of unstable right triangle shaped welding pieces.

At the same time, the rear gate ASSY 14 is closed and the container 10 having the upper opening is loaded up to the maximum loading amount.

このとき、図１〜図８に示すように、フロアパネルＡＳＳＹ１２の一部を構成する各フロアパネル１７，１７Ａ，クロスメンバ１８およびサブフレーム１９と、フロントパネルＡＳＳＹ１３の一部を構成するフロントパネル２９および前板用補強板３０と、リアゲートＡＳＳＹ１４の一部を構成するリアゲートパネル３７および後板用補強板３８と、左右一対のサイドパネルＡＳＳＹ１５，１６の一部を構成する各サイドパネル４４および対応する各側板用補強板４５との素材として、従来の普通鋼より高強度な耐摩耗鋼板を採用した。これにより、材料使用量が減少し、オープントップコンテナ１０の軽量化が図れて、その分だけスクラップＳの積載量を増大させることができるとともに、フロアパネルＡＳＳＹ１２、フロントパネルＡＳＳＹ１３、リアゲートＡＳＳＹ１４および各サイドパネルＡＳＳＹ１５，１６の疲労破壊を防止することができる。 At this time, as shown in FIGS. 1 to 8, each floor panel 17, 17A, a cross member 18, and a subframe 19 which form a part of the floor panel ASSY12, and a front panel 29 which forms a part of the front panel ASSY13. Further, the front plate reinforcing plate 30, the rear gate panel 37 and the rear plate reinforcing plate 38 that form a part of the rear gate ASSY 14, the side panels 44 that form a part of the pair of left and right side panels ASSY 15, 16 and the corresponding As a material for the side plate reinforcing plate 45, a wear-resistant steel plate having higher strength than the conventional ordinary steel was adopted. As a result, the amount of material used is reduced, the weight of the open top container 10 can be reduced, and the load of the scrap S can be increased accordingly, and the floor panel ASSY12, the front panel ASSY13, the rear gate ASSY14, and each side. Fatigue failure of the panels ASSY 15 and 16 can be prevented.

すなわち、コンテナ１０に多量のスクラップＳを積み込んだ場合には、フロアパネルＡＳＳＹ１２、フロントパネルＡＳＳＹ１３、リアゲートＡＳＳＹ１４および左右一対の各サイドパネルＡＳＳＹ１５，１６の各中央部が、多量のスクラップＳにより内方から外方に向かって押されて膨らもうとする。しかしながら、これらは普通鋼より硬い耐摩耗鋼板からなるため、フロアパネルＡＳＳＹ１２および各パネルＡＳＳＹ１３〜１６の中央部の変形は抑制される。
特に、図７に示すように、リアゲートＡＳＳＹ１４の外面を後板用補強板３８により補強したため、スクラップ満載時におけるリアゲートＡＳＳＹ１４の外方への膨出量を抑えることができる。これにより、リアゲートＡＳＳＹ１４の外方への膨出を原因としたフロアパネルＡＳＳＹ１２の後端面とリアゲートＡＳＳＹ１４の内面との間に隙間が生じることを防ぎ、結果としてこの隙間からのスクラップＳの落下を防止することができる。 That is, when a large amount of scrap S is loaded in the container 10, the respective center portions of the floor panel ASSY 12, the front panel ASSY 13, the rear gate ASSY 14, and the pair of left and right side panels ASSY 15, 16 are internally scraped by the large amount of scrap S. It is pushed outward and tries to swell. However, since these are made of wear-resistant steel plates that are harder than ordinary steel, deformation of the central portions of the floor panel ASSY12 and the panels ASSY13 to 16 is suppressed.
In particular, as shown in FIG. 7, since the outer surface of the rear gate ASSY 14 is reinforced by the rear plate reinforcing plate 38, the outward expansion amount of the rear gate ASSY 14 when the scrap is fully loaded can be suppressed. This prevents a gap from being formed between the rear end surface of the floor panel ASSY12 and the inner surface of the rear gate ASSY14 due to the outward bulging of the rear gate ASSY14, and consequently prevents the scrap S from falling from this gap. can do.

しかも、耐摩耗鋼板は普通鋼に比べて弾性限界点が高い。そのため、搬送先でスクラップＳを荷降ろしすれば、フロアパネルＡＳＳＹ１２および各パネルＡＳＳＹ１３〜１６への応力が取り除かれ、これらは塑性変形することなく、元の平坦なフロアパネルＡＳＳＹ１２や各パネルＡＳＳＹ１３〜１６に復元する。その結果、フロアパネルＡＳＳＹ１２や各パネルＡＳＳＹ１３〜１６が多量のスクラップＳの投入による繰り返し応力を受けても、これらの中央部の機械的強度はほとんど低下せず、フロアパネルＡＳＳＹ１２、フロントパネルＡＳＳＹ１３、リアゲートＡＳＳＹ１４および各サイドパネルＡＳＳＹ１５，１６の疲労破壊が抑制される。
また、このようにフロアパネルＡＳＳＹ１２および各パネルＡＳＳＹ１３〜１６の素材として耐摩耗鋼板を採用したため、普通鋼に比べて摩耗しにくい。その結果、スクラップローダーなどを操縦し、スクラップＳをコンテナ１０に投入した際、スクラップＳがフロアパネルＡＳＳＹ１２および各パネルＡＳＳＹ１３〜１６の内面に衝突し、擦れが生じても、従来品よりこれらの摩耗を低減することができる。 Moreover, the wear-resistant steel plate has a higher elastic limit point than the ordinary steel. Therefore, if the scrap S is unloaded at the destination, the stress on the floor panel ASSY12 and each panel ASSY13 to 16 is removed, and these do not undergo plastic deformation, and the original flat floor panel ASSY12 and each panel ASSY13 to 16 are removed. Restore to. As a result, even if the floor panel ASSY12 and each of the panels ASSY13 to 16 are subjected to repeated stress due to the input of a large amount of scrap S, the mechanical strength of the central portion of the floor panel ASSY12, the front panel ASSY13, the rear gate is not substantially reduced. Fatigue fracture of ASSY14 and each side panel ASSY15, 16 is suppressed.
Further, since the wear-resistant steel plate is used as the material of the floor panel ASSY12 and each of the panels ASSY13 to 16 in this manner, it is less likely to wear as compared with ordinary steel. As a result, when the scrap loader or the like is operated and the scrap S is loaded into the container 10, the scrap S collides with the inner surfaces of the floor panel ASSY 12 and each of the panels ASSY 13 to 16 and even if rubbing occurs, these scraps are worn more than the conventional products. Can be reduced.

さらに、従来のようにクロスメンバとサブフレームとを上下２段に溶接するのではなく、クロスメンバ１８とサブフレーム１９とを突き合わせ状態で溶接したため、その分、コンテナ１０の高さが低くなってコンテナ１０の重心が下がり、スクラップ輸送中のコンテナセミトレーラ１１の走行安定性を高めることができる。
また、ここでは各クロスメンバ１８および各サブフレーム１９を、それぞれ所定サイズの耐摩耗鋼板をプレス成型して作製されるようにしたため、例えば、クロスメンバ１８とサブフレーム１９とを１本の断面コの字状の耐摩耗鋼板から切り分けることも可能で、オープントップコンテナ１０の部品点数を低減することができる。
さらにまた、従来は直角三角形状の多数の溶接片材を介して、クロスメンバ１８とサブフレーム１９とを溶接していたが、これに比べて、部品点数がさらに低減するとともに溶接が容易となる。 Further, since the cross member and the sub-frame 19 are welded in a butted state with each other instead of welding the cross member and the sub-frame in upper and lower two stages as in the conventional case, the height of the container 10 is reduced accordingly. The center of gravity of the container 10 is lowered, and the running stability of the container semi-trailer 11 during scrap transportation can be improved.
Further, here, since each cross member 18 and each sub-frame 19 is made by press-molding a wear-resistant steel plate of a predetermined size, for example, the cross member 18 and the sub-frame 19 have It is also possible to cut it from the wear-resistant steel plate in the shape of V, and the number of parts of the open top container 10 can be reduced.
Furthermore, conventionally, the cross member 18 and the sub-frame 19 are welded through a large number of right-angled triangular shaped welding pieces, but compared to this, the number of parts is further reduced and welding is facilitated. ..

また、各クロスメンバ１８および各サブフレーム１９は、コの字状の断面において、コの字の各バーチカルサイド１８ａ，１９ａの部分をコの字のラテラルサイド１８ｂ，１９ｂの部分より短くしている（図５（ａ），（ｂ））。そのため、耐摩耗鋼板が高硬度素材であるにも拘らずプレス成型がし易い。 Further, in each cross member 18 and each sub-frame 19, in the U-shaped cross section, the vertical side portions 18a, 19a of the U-shape are shorter than the lateral sides 18b, 19b of the U-shape. (FIGS. 5(a) and 5(b)). Therefore, although the wear-resistant steel plate is a high hardness material, it is easy to press-form.
