An appropriate number of side girder inner intermediate walls p12 (this book) formed between the inner wall p11, the side girder outer wall p10 and the side girder inner wall p11 and substantially parallel to the side girder outer wall p10 and the side girder inner wall p11. In the embodiment, two side girder inner intermediate walls are formed.). Further, the side girder outer wall p10, the side girder inner wall p11, and the side girder inner wall p12 are located in the side girder P1, and a known upper deck board p1a that forms the upper deck board p1 and the lower deck. A known lower deck board crosspiece p2c forming the board p2 is connected.
中間桁P2は、フォーク挿入孔p4に沿った、相対する中間桁壁p20と、相対する中間桁壁p20間に形成された、中間桁内中間壁p21(本実施例においては、2枚の中間桁内中間壁が形成されている。)とを有している。また、中間桁壁p20及び中間桁内中間壁p21は、中間桁P2内に位置する、上部デッキボードp1を形成する公知の上部デッキボード桟p1aと、下部デッキボードp2を形成する公知の下部デッキボード桟p2cとを連結するように構成されている。 The intermediate beam P2 is formed between the opposed intermediate beam wall p20 and the opposed intermediate beam wall p20 along the fork insertion hole p4, and an intermediate wall p21 in the intermediate beam (in the present embodiment, two intermediate beams). An intermediate wall in the beam is formed). Further, the intermediate girder wall p20 and the intermediate girder inner middle wall p21 are located in the intermediate girder P2 and are a known upper deck board bar p1a that forms the upper deck board p1 and a known lower deck that forms the lower deck board p2. It is comprised so that board crosspiece p2c may be connected.
側部桁P1内には、側部桁内壁p11に連接されているとともに、上部デッキボード桟p1aと下部デッキボード桟p2cに連結され、且つ、側部桁内壁p11に略垂直なフォーク挿入孔側補強片p13が形成されている。また、側部桁P1内には、側部桁外壁p10に連接されているとともに、上部デッキボード桟p1aと下部デッキボード桟p2cに連結され、且つ、側部桁外壁p10に略垂直な側部桁外壁側補強片p14が形成されている。 The side girder P1 is connected to the side girder inner wall p11 and is connected to the upper deck board bar p1a and the lower deck board bar p2c and is substantially perpendicular to the side girder inner wall p11. A reinforcing piece p13 is formed. In the side girder P1, the side girder is connected to the side girder outer wall p10 and is connected to the upper deck board bar p1a and the lower deck board bar p2c and is substantially perpendicular to the side girder outer wall p10. A girder outer wall side reinforcing piece p14 is formed.
上述したように、側部桁P1内に、フォーク挿入孔側補強片p13及び側部桁外壁側補強片p14を形成することにより、側部桁P1の強度や剛性を高めることができる。 As described above, the strength and rigidity of the side beam P1 can be increased by forming the fork insertion hole side reinforcing piece p13 and the side beam outer wall side reinforcing piece p14 in the side beam P1.
同様に、中間桁P2内には、相対する中間桁壁p20に連接されているとともに、上部デッキボード桟p1aと下部デッキボード桟p2cに連結され、且つ、中間桁壁p20に略垂直な中間桁補強片p15が形成されている。 Similarly, in the intermediate beam P2, an intermediate beam connected to the opposite intermediate beam wall p20 and connected to the upper deck board bar p1a and the lower deck board bar p2c and substantially perpendicular to the intermediate beam wall p20. A reinforcing piece p15 is formed.
上述したように、中間桁P2内に、中間桁補強片p15を形成することにより、中間桁P2の強度や剛性を高めることができる。 As described above, the strength and rigidity of the intermediate beam P2 can be increased by forming the intermediate beam reinforcement piece p15 in the intermediate beam P2.
側部桁P1の側部桁内壁p11と下部端部桟p2aとにより形成される隅部、及び、側部桁P1の側部桁内壁p11と下部中央桟p2bとにより形成される隅部には、側部桁内壁p11の下端部を、側部桁内壁p11に沿って、フォーク挿入孔p4側に、直線状或いは湾曲状に変形させることにより、側部桁内壁p11の下端部には、側部桁内壁p11の傾斜補強部p30が形成されている。傾斜補強部p30は、略垂直な側部桁内壁p11と、該側部桁内壁p11より、フォーク挿入孔p4側に位置する略垂直な内壁下端部p11aとの間に形成されているとともに、側部桁内壁p11、内壁下端部p11a及び傾斜補強部p30の肉厚は、均一に形成されている。また、このような傾斜補強部p30は、フォーク挿入孔p4側に位置する側部桁P1の側部桁内壁p11の全長に亘たって形成されている。このように、フォーク挿入孔側補強片p13を形成することにより、傾斜補強部p30と側部桁内壁p11の内壁下端部p11aとを補強することができる。 The corner formed by the side girder inner wall p11 and the lower end crosspiece p2a of the side girder P1 and the corner formed by the side girder inner wall p11 and the lower central crosspiece p2b of the side girder P1 By deforming the lower end portion of the side girder inner wall p11 along the side girder inner wall p11 to the fork insertion hole p4 side in a straight line or a curved shape, An inclined reinforcement part p30 of the inner wall p11 of the part beam is formed. The inclined reinforcing portion p30 is formed between a substantially vertical side girder inner wall p11 and a substantially vertical inner wall lower end p11a located on the fork insertion hole p4 side from the side girder inner wall p11. The thicknesses of the inner wall p11, the inner wall lower end p11a, and the inclined reinforcing part p30 are formed uniformly. Moreover, such an inclination reinforcement part p30 is formed over the full length of the side part inner wall p11 of the side part beam P1 located in the fork insertion hole p4 side. Thus, by forming the fork insertion hole side reinforcing piece p13, the inclined reinforcing portion p30 and the inner wall lower end portion p11a of the side beam inner wall p11 can be reinforced.
同様に、中間桁P2の中間桁壁p20と下部端部桟p2aとにより形成される隅部、及び、中間桁P2の中間桁壁p20と下部中央桟p2bとにより形成される隅部にも、中間桁壁p20の下端部を、中間桁壁p20に沿って、フォーク挿入孔p4側に、直線状或いは湾曲状に変形させることにより、中間桁壁p20の下端部には、中間桁壁p20の傾斜補強部p31が形成されている。傾斜補強部p31は、略垂直な中間桁壁p20と、該中間桁壁p20より、フォーク挿入孔p4側に位置する略垂直な中間桁壁20の下端部p20aとの間に形成されているとともに、中間桁壁p20、中間桁壁20の下端部p20a及び傾斜補強部p31の肉厚は、均一に形成されている。また、このような傾斜補強部p31は、フォーク挿入孔p4側に位置する中間桁P2の中間桁壁p20の全長に亘たって形成されている。このように、中間桁補強片p15を形成することにより、傾斜補強部p30と中間桁壁20の下端部p20aを補強することができる。 Similarly, the corner formed by the intermediate beam wall p20 of the intermediate beam P2 and the lower end beam p2a and the corner formed by the intermediate beam wall p20 of the intermediate beam P2 and the lower central beam p2b are also provided. By deforming the lower end portion of the intermediate girder wall p20 along the intermediate girder wall p20 toward the fork insertion hole p4 in a linear or curved shape, the lower end portion of the intermediate girder wall p20 An inclined reinforcing portion p31 is formed. The inclined reinforcing portion p31 is formed between the substantially vertical intermediate girder wall p20 and the lower end portion p20a of the substantially vertical intermediate girder wall 20 located on the fork insertion hole p4 side from the intermediate girder wall p20. The wall thickness of the intermediate girder wall p20, the lower end part p20a of the intermediate girder wall 20, and the inclined reinforcing part p31 is formed uniformly. Further, such an inclined reinforcing portion p31 is formed over the entire length of the intermediate beam wall p20 of the intermediate beam P2 located on the fork insertion hole p4 side. Thus, by forming the intermediate beam reinforcing piece p15, the inclined reinforcing portion p30 and the lower end portion p20a of the intermediate beam wall 20 can be reinforced.
上述したように、略垂直な側部桁内壁p11と、該側部桁内壁p11より、フォーク挿入孔p4側に位置する略垂直な内壁下端部p11aとの間に、傾斜補強部p30を形成することにより、また、略垂直な中間桁壁p20と、該中間桁壁p20より、フォーク挿入孔p4側に位置する略垂直な下端部p20aとの間に、傾斜補強部p31を形成することにより、側部桁P1及び中間桁P2と、側部桁P1及び中間桁P2とを連結する下部端部桟p2aと下部中央桟p2bとの連結部の強度を高めることができ、ひいては、下部端部桟p2aと下部中央桟p2bの曲げ強度が向上し、従って、一体成形2方差しパレットPの強度や剛性を高めることができる。 As described above, the inclined reinforcing portion p30 is formed between the substantially vertical side girder inner wall p11 and the substantially vertical inner wall lower end p11a located on the fork insertion hole p4 side from the side girder inner wall p11. In addition, by forming the inclined reinforcing part p31 between the substantially vertical intermediate girder wall p20 and the substantially vertical lower end part p20a located on the fork insertion hole p4 side from the intermediate girder wall p20, The strength of the connecting portion between the lower end beam p2a and the lower central beam p2b that connects the side beam P1 and the intermediate beam P2 and the side beam P1 and the intermediate beam P2 can be increased. The bending strength of p2a and lower center crosspiece p2b is improved, and therefore the strength and rigidity of the integrally formed two-way pallet P can be increased.
