ukwaziswa kwemveliso
Ibhokisi yentsimbi yentsimbi yenziwe ngepleyiti ephezulu, ipleyiti engezantsi, iwebhu, isahlulo esinqamlezileyo kunye ne-longitudinal and transverse stiffeners. Iifom zayo ezisetyenziswa ngokuqhelekileyo ezinqamlezileyo ziquka ibhokisi enye igumbi elinye, ibhokisi enye amagumbi amathathu, ibhokisi kabini igumbi elinye, iibhokisi ezintathu igumbi elinye, Iibhokisi ezininzi-igumbi elinye, trapezoid inverted kunye webs inclined, ibhokisi enye-ibhokisi multi-chamber ngaphezu I-3 webs, i-flat iron girder girder, njl. Phakathi kwazo, icandelo lebhokisi lebhokisi lentsimbi elisetyenziswa kakhulu liyi-double-box single-chamber, kunye ne-multi-box single-chamber isetyenziselwa iibhulorho ezinobubanzi obukhulu bebhuloho. Isibambiso sebhokisi yentsimbi esicaba sinomlinganiselo omncinci wobude be-beam ukuya kububanzi be-beam, kwaye isetyenziswa ikakhulu kwimiqadi eneembambo ezinje ngeebhulorho zokunqunyanyiswa, iibhulorho ezihlala ngekhebula, kunye neebhulorho zearch. Ayifane isetyenziswe kwiibhulorho ze-beam. Ibhokisi enye ye-multi-chamber steel girder ene-webs engaphezu kwe-3 ayilula ukwenza kunye nokuyifaka, ngoko ayifane isetyenziswe.
Ikwahlulahlulwe ngamacandelo amaninzi e-boam yokuvelisa kunye nokufakwa, kwaye icandelo layo elinqamlekileyo lineempawu zemilo ebanzi kunye neflethi, kwaye umyinge we-aspect ratio ufikelela malunga ne-1:10. Umbhinqo webhokisi yentsimbi wenziwe ngokubanzi ngokuwelda ngokupheleleyo ipleyiti ephezulu, ipleyiti esezantsi, iwebhu, kunye nezahlulo ezinqamlezileyo, izahlulo zelongitudinal kunye nezilukhuni. Ipleyiti ephezulu yidekhi yebhulorho ye-orthotropic eyenziwe ngecwecwe lokugubungela kunye ne-longitudinal stiffeners. Ubukhulu bepleyiti nganye yebhokisi yentsimbi eqhelekileyo inokuba: ubukhulu be-cover 14mm, ubude be-U-shaped rib thickness 6mm, ububanzi bomlomo ophezulu 320mm, ububanzi bomlomo ophantsi 170mm, ukuphakama 260mm, isithuba se-620mm; ipleyiti esezantsi ubukhulu 10mm, longitudinal U-shaped stiffeners; Ubukhulu bewebhu ethambekeleyo yi-14mm, ubukhulu bewebhu ephakathi yi-9mm; isithuba sezahlulo ezinqamlezileyo yi-4.0m, kwaye ubukhulu yi-12mm; ukuphakama kwe-beam yi-2 ~ 3.5m.

izicelo Product
Ngenxa yefom yesakhiwo, i-steel box girder isetyenziswa ngokubanzi kumasipala ophakamileyo kunye ne-ramp iron girder; umbutho ixesha lokwakha traffic ixesha elide ibhulorho cable-wahlala, ibhulorho ukunqunyanyiswa, ibhulorho ibhulorho stiffening girder kunye ibhulorho ngeenyawo ibhulorho intsimbi ibhokisi girder.
