Description

本発明は車両の荷台床搭載方法及び荷台床搭載構造に関するものである。   The present invention relates to a loading platform mounting method and a loading platform mounting structure for a vehicle.

従来、トラックの荷台床は、シャシフレームのサイドレールの長手方向に沿って載置され且つ当該サイドレールにＵボルト等の締結手段で固定した左右の縦根太と、両端が車両側方へ向けて突出するように前後方向に適宜の間隔で左右の縦根太上に掛け渡され且つ当該縦根太にボルト等の締結手段で固定した複数の横根太とにより積み重ね井桁形状の床枠構造を構成し、この床枠構造で平型荷台や箱形荷台の床材を支えるようにしている。   Conventionally, the truck bed is mounted along the longitudinal direction of the side rails of the chassis frame and fixed to the side rails by fastening means such as U-bolts, and both left and right vertical joists are directed to the side of the vehicle. A plurality of horizontal joists spanned on the left and right vertical joists at appropriate intervals in the front-rear direction so as to protrude and constitute a floor frame structure of a stacked well girder shape with a plurality of horizontal joists fixed by fastening means such as bolts, etc. This floor frame structure supports the floor material of a flat type carrier box or a box type carrier.

平型荷台に積載可能な貨物の大きさ（高さ）、あるいは箱形荷台の収納容積を考慮すると、床枠構造の厚みを減らして荷台の低床化を図ることが望ましい。   Considering the size (height) of cargo that can be loaded on a flat type carrier, or the storage capacity of a box type carrier, it is desirable to reduce the thickness of the floor frame structure and reduce the floor of the carrier.

そこで、荷台床面を構成する床板部と、当該床板部の下面にあってサイドレールに沿う左右の縦根太部とを、繊維強化プラスチックにより中空状に且つ一体的に形成し、更に、繊維強化プラスチックの外殻に発泡樹脂材料を封入して外殻の変形を抑制するコアとした荷台の床板材が提案されている（例えば、特許文献１参照）。
特開平９−３０１２２５号公報 Therefore, the floor plate portion constituting the cargo bed floor surface and the left and right vertical joists along the side rails on the lower surface of the floor plate portion are integrally formed in a hollow shape with fiber reinforced plastic, and further fiber reinforced. There has been proposed a floor plate material for a cargo bed, in which a foamed resin material is enclosed in a plastic outer shell to suppress deformation of the outer shell (see, for example, Patent Document 1).
JP-A-9-301225

しかしながら、前記床板材のような大きな構成部材を、強化材としての繊維を適切な状態で配置して形成することは簡単ではなく、特許文献１のものは生産性の向上が期待できない。   However, it is not easy to form a large structural member such as the floor board material by arranging fibers as a reinforcing material in an appropriate state, and the one of Patent Document 1 cannot be expected to improve productivity.

また特許文献１のものは、言わば発泡樹脂を繊維強化プラスチックで包んだような構造であるので、床枠構造の厚みを効果的に削減することができず、また、剛性不足に起因した共振の発生も懸念される。   In addition, since the structure of Patent Document 1 is a structure in which foamed resin is wrapped with fiber reinforced plastic, the thickness of the floor frame structure cannot be effectively reduced, and resonance due to insufficient rigidity is also caused. Occurrence is also a concern.

更に特許文献１のものは、床板材のような大きな部材とサイドレールに沿って延びる長大な縦根太部とを繊維強化プラスチックによって一体的に形成しているが、その形成には多大の時間が掛り生産性が低いと共に、非常に高い技術が要求されるために荷台床の価格が非常に高価になってしまう問題がある。   Furthermore, although the thing of patent document 1 integrally forms the big member like a floorboard material and the elongate vertical joist part extended along a side rail with fiber reinforced plastics, it takes a lot of time for the formation. In addition to low productivity, there is a problem that the price of the cargo bed becomes very expensive because very high technology is required.

本発明は上述した実情に鑑みてなしたもので、床枠ブロックの厚みを減らすことができ、更に生産性を高めて価格を低く抑えることができ、且つ車両に対する搭載性を高め得る荷台床搭載方法及び荷台床搭載構造を提供することを目的としている。   The present invention has been made in view of the above-described circumstances, and can reduce the thickness of the floor frame block, can further increase the productivity, keep the price low, and can improve the mountability to the vehicle. It is an object to provide a method and a loading platform mounting structure.

本発明においては、車両の荷台床を長手方向に複数に分割した形状の床枠ブロックを軽合金鋳造により製造する。この床枠ブロックの長手方向端面を当接させた状態にして複数の隣接する床枠ブロック同士を上側と下側の組立固定材で固定し、これによって曲げ強度を有する所定長さの荷台床を組み立てる。そして、この荷台床を車両のサイドレール上に搭載して位置決めし、各床枠ブロックの縦梁をサイドレールに締結する。   In this invention, the floor frame block of the shape which divided | segmented the loading platform floor of the vehicle into the longitudinal direction is manufactured by light alloy casting. A plurality of adjacent floor frame blocks are fixed with the upper and lower assembly fixing materials in a state in which the longitudinal end surfaces of the floor frame blocks are in contact with each other, whereby a loading platform floor having a predetermined length having bending strength is obtained. assemble. And this loading platform floor is mounted and positioned on the side rail of the vehicle, and the vertical beam of each floor frame block is fastened to the side rail.

Even if the floor frame block is made thin, it can maintain high strength. In addition, by fixing a plurality of floor frame blocks with an assembly fixing material and assembling the cargo bed floor, this cargo bed floor is mounted on the side rails in a lump, making it easy to mount the floor frame blocks on the side rails, Furthermore, the positioning of each floor frame block with respect to the side rail is facilitated, and the fastening operation of each floor frame block with respect to the side rail is facilitated.

上記形態において、車両のサイドレール１上に荷台床９を搭載する手順について説明する。   In the above embodiment, a procedure for mounting the cargo bed floor 9 on the side rail 1 of the vehicle will be described.

図１、図２及び図４に示す形状を有する複数の床枠ブロック６をアルミニウム鋳造により製造する。この床枠ブロック６は、車両に設けられる荷台床を長手方向に複数分割した形状とする。   A plurality of floor frame blocks 6 having the shapes shown in FIGS. 1, 2 and 4 are manufactured by aluminum casting. The floor frame block 6 has a shape in which a cargo bed floor provided in a vehicle is divided into a plurality of parts in the longitudinal direction.

図４に示す如く、地上或いは作業台上において、車両の荷台床を構成するのに必要な数の床枠ブロック６を、端面ａが互いに当接するように配置し、固定孔１５にボルト（図示せず）を通して、端面ａ同士を相互に締結する。続いて、床枠ブロック６の隣接する端部に形成した上側の連結嵌合溝１１と下側の連結嵌合溝１２に組立固定材７，８を夫々を嵌合配置し、該組立固定材７，８の固定孔１４と連結嵌合溝１１，１２の固定孔１３にボルト１６（図８）を通して締付けることにより、図４に示すような所定長さの荷台床９を組み立てる。   As shown in FIG. 4, the floor frame blocks 6 as many as necessary for constituting the loading platform floor of the vehicle are arranged on the ground or on the work table so that the end faces a come into contact with each other, and bolts (see FIG. The end faces a are fastened to each other through (not shown). Subsequently, the assembly fixing materials 7 and 8 are fitted and arranged in the upper connection fitting groove 11 and the lower connection fitting groove 12 formed at the adjacent ends of the floor frame block 6, respectively. By fastening bolts 16 (FIG. 8) to the fixing holes 14 of FIGS. 7 and 8 and the fixing holes 13 of the coupling fitting grooves 11 and 12, a loading bed 9 having a predetermined length as shown in FIG. 4 is assembled.

このようにして組み立てた荷台床９は、図７、図８に示すように車両のサイドレール１上に一括搭載する。この時、各床枠ブロック６は端面ａ同士を図示しないボルトで相互に締結し、且つ上側と下側の組立固定材７，８で一体に組み立てているので、荷台床９の床枠ブロック６に図６の白抜き矢印の方向の曲げ力が作用したときは、端面ａが互いに突っ張って上側の組立固定材７の引っ張り力により支持し、また、床枠ブロック６に図６の黒矢印の方向の曲げ力が作用したときは、端面ａが互いに突っ張って下側の組立固定材８の引っ張り力により支持するので、荷台床９の曲げ強度が保持され、よって荷台床９を安定して車両のサイドレール１上に搭載することができる。   The load carrier floor 9 assembled in this way is collectively mounted on the side rails 1 of the vehicle as shown in FIGS. At this time, since the floor frame blocks 6 are fastened to each other with bolts (not shown) at the end faces a and are assembled integrally with the upper and lower assembly fixing members 7 and 8, the floor frame block 6 of the loading bed floor 9. When the bending force in the direction of the white arrow in FIG. 6 is applied, the end surfaces a are stretched to support each other by the pulling force of the upper assembly fixing member 7 and the floor frame block 6 is also provided with the black arrow in FIG. When the bending force in the direction is applied, the end surfaces a are stretched and supported by the pulling force of the lower assembly fixing material 8, so that the bending strength of the cargo bed floor 9 is maintained, so that the cargo bed floor 9 is stably maintained in the vehicle. It can be mounted on the side rail 1.

搭載した荷台床９をサイドレール１に対して位置決めした後、前記各床枠ブロック６の縦梁２を、図９又は図１０に示す締結手段１７を用いてサイドレール１に締結する。この時、各床枠ブロック６は締結手段１７によってサイドレール１に強固に締結されるが、前記各床枠ブロック６は簡単な構成の上下の組立固定材７，８によって一体に組み立てられているので、サイドレール１上に搭載した荷台床９の強度を高めることができ、且つサイドレール１上に搭載される荷台床９の上下の厚さを薄くすることができる。   After the loaded carrier floor 9 is positioned with respect to the side rail 1, the vertical beam 2 of each floor frame block 6 is fastened to the side rail 1 using the fastening means 17 shown in FIG. 9 or FIG. At this time, each floor frame block 6 is firmly fastened to the side rail 1 by the fastening means 17, but each floor frame block 6 is integrally assembled by the upper and lower assembly fixing members 7 and 8 having a simple configuration. Therefore, the strength of the loading platform floor 9 mounted on the side rail 1 can be increased, and the upper and lower thicknesses of the loading platform floor 9 mounted on the side rail 1 can be reduced.

上記したように、組立固定材７，８によって組み立てた複数の床枠ブロック６がサイドレール１上に装備されるので、各床枠ブロック６によって平型荷台や箱形荷台の床材を支持することができる。   As described above, since the plurality of floor frame blocks 6 assembled by the assembly fixing members 7 and 8 are mounted on the side rails 1, the floor frame block 6 supports the floor material of the flat type carrier box or the box type carrier. be able to.

従って、上記したように車体長手方向に並べる床枠ブロック６の数を増減することにより、単一種の床枠ブロック６で異なる長さの荷台に対応することができる。   Therefore, by increasing or decreasing the number of floor frame blocks 6 arranged in the longitudinal direction of the vehicle body as described above, a single type of floor frame block 6 can correspond to different length loading platforms.

図１１、図１２（Ａ）、（Ｂ）は、Ｕ字ボルトによる締結手段を用いて前記床枠ブロック６をサイドレール１上に締結する場合の形態を示したものである。この形態では、床枠ブロック６に備える縦梁２が、鉛直の外面板２ａと内面板２ｂとを有しており、該外面板２ａと内面板２ｂとの間に前記上側の連結嵌合溝１１と下側の連結嵌合溝１２とを形成しており、且つ前記上側の連結嵌合溝１１と下側の連結嵌合溝１２との間における外面板２ａと内面板２ｂには水平な孔２３を形成している。   FIGS. 11, 12 </ b> A, and 12 </ b> B show forms when the floor frame block 6 is fastened on the side rail 1 using fastening means using U-bolts. In this embodiment, the vertical beam 2 provided in the floor frame block 6 has a vertical outer surface plate 2a and an inner surface plate 2b, and the upper coupling fitting groove is provided between the outer surface plate 2a and the inner surface plate 2b. 11 and the lower connection fitting groove 12 are formed on the outer surface plate 2a and the inner surface plate 2b between the upper connection fitting groove 11 and the lower connection fitting groove 12. A hole 23 is formed.

上記した床枠ブロック６は、図４と同様に長手方向に複数配置し、上側と下側の連結嵌合溝１１，１２に組立固定材７，８を嵌合配置して通しボルト２４で締結する（図１２（Ａ））ことにより荷台床９を組み立てる。そして、組み立てた荷台床９を図１２（Ａ）、（Ｂ）に示す如くサイドレール１上に搭載して位置決めし、締結手段１７によりサイドレール１に締結する。このとき、締結手段１７は、前記孔２３に孔開き組立固定材２５を通し、該孔開き組立固定材２５の孔（図示せず）にＵ字ボルト２６を通してナット２７を締付けることにより縦梁２をサイドレール１に締結する。上記において、Ｕ字ボルト２６の上端は床枠ブロック６の上面から突出しないようにしている。   A plurality of the above-described floor frame blocks 6 are arranged in the longitudinal direction in the same manner as in FIG. 4, and the assembly fixing members 7 and 8 are fitted and arranged in the upper and lower connection fitting grooves 11 and 12 and fastened with a through bolt 24 (FIG. 12A) assembles the cargo bed floor 9. Then, the assembled cargo bed floor 9 is mounted on the side rail 1 and positioned as shown in FIGS. 12A and 12B, and fastened to the side rail 1 by the fastening means 17. At this time, the fastening means 17 passes the hole assembly fixing material 25 through the hole 23, and tightens the nut 27 through the U-bolt 26 in the hole (not shown) of the hole assembly fixing material 25, thereby fixing the vertical beam 2. Is fastened to the side rail 1. In the above, the upper end of the U-shaped bolt 26 does not protrude from the upper surface of the floor frame block 6.

上記各形態に示したように、床枠ブロック６は車両に設けられる荷台床を長手方向に複数分割した形状としているので、床枠ブロック６の形状が小型になることによって製造が容易になると共に、前記床枠ブロック６は厚さを薄くしても高い強度を保持できる。更に、複数の床枠ブロック６を上下の組立固定材７，８で固定して組み立てた荷台床９をサイドレール１上に一括して搭載するため、サイドレール１上への床枠ブロックの搭載作業が容易になる。また、サイドレール１に対する各床枠ブロック６の位置決めが容易になってサイドレール１に対する各床枠ブロック６の締結作業が容易になる。更に、床枠ブロック６相互を簡単な構成の上下の組立固定材７，８で固定して荷台床９を組み立てるので、サイドレール１上に搭載する荷台床９の上下の厚さを薄くできる。   As shown in each of the above embodiments, the floor frame block 6 has a shape obtained by dividing a cargo bed floor provided in a vehicle into a plurality of parts in the longitudinal direction. The floor frame block 6 can maintain high strength even when the thickness is reduced. Furthermore, since the loading platform floor 9 assembled by fixing the plurality of floor frame blocks 6 with the upper and lower assembly fixing materials 7 and 8 is mounted on the side rails 1 at a time, the floor frame blocks are mounted on the side rails 1. Work becomes easy. Further, the positioning of each floor frame block 6 with respect to the side rail 1 is facilitated, and the fastening operation of each floor frame block 6 with respect to the side rail 1 is facilitated. Furthermore, since the loading platform floor 9 is assembled by fixing the floor frame block 6 with the upper and lower assembly fixing members 7 and 8 having a simple configuration, the upper and lower thicknesses of the loading platform floor 9 mounted on the side rail 1 can be reduced.

一方、床枠ブロック６の上面と下面に、組立固定材７，８が嵌合する連結嵌合溝１１，１２を形成したので、連結した床枠ブロック６の横の動きを抑制して荷台床９の横方向の強度も高めることができる。   On the other hand, since the connecting fitting grooves 11 and 12 into which the assembly fixing materials 7 and 8 are fitted are formed on the upper and lower surfaces of the floor frame block 6, the lateral movement of the connected floor frame block 6 is suppressed and the bed floor is suppressed. The horizontal strength of 9 can also be increased.

また、前記したように、複数の床枠ブロック６を上下の組立固定材７，８で固定した高い強度を有する荷台床９をサイドレール１上に装備することができるので、各床枠ブロック６によって平型荷台や箱形荷台の床材を高い強度で支持できるようになる。   Further, as described above, since the load carrier floor 9 having a high strength in which the plurality of floor frame blocks 6 are fixed by the upper and lower assembly fixing materials 7 and 8 can be provided on the side rail 1, each floor frame block 6 Therefore, it becomes possible to support the floor material of a flat type carrier or a box type carrier with high strength.

更に、車体長手方向に並べる床枠ブロック６の数を増減することにより、単一種の床枠ブロック６で異なる長さの荷台に対応することができる。   Further, by increasing or decreasing the number of floor frame blocks 6 arranged in the longitudinal direction of the vehicle body, a single type of floor frame block 6 can correspond to different lengths of loading platforms.
