Simbi bhokisi danda, inonziwo simbi bhokisi girder, inowanzoshandiswa zvimiro fomu marefu-span mabhiriji.Kazhinji inoshandiswa pamabhiriji makuru-span, inonzi simbi yebhokisi girder nokuti inoratidzika sebhokisi.Inogona kugoverwa mumhando nhatu: single box girder bridge, double box girder bridge, uye multiple box girder bridge.
Mumabhiriji makuru-anotsigirwa netambo, bhokisi resimbi guru girder rinotambanuka mazana emamita kana kunyange zviuru zvemamita.
Iyo yakakamurwa kuita akati wandei danda zvikamu zvekugadzira uye kuisirwa, uye chikamu chayo chemuchinjiko chine hunhu hwehupamhi uye hwakatsetseka chimiro, uye chikamu chechiyero chinosvika pa1:10.Simbi bhokisi girder rinowanzo kuumbwa nekukwenenzverwa kwepamusoro ndiro, pasi ndiro, webhu, uye transverse partitions, longitudinal partitions uye stiffeners.Iyo ndiro yepamusoro ndeye orthotropic bhiriji deki inoumbwa nekavharo ndiro uye longitudinal stiffeners.Ukobvu hwendiro yega yega yesimbi yebhokisi girder inogona kuva: kuvharidzira ukobvu 14mm, longitudinal U-yakaita mbabvu ukobvu 6mm, muromo wepamusoro wakafara 320mm, muromo wezasi wakafara 170mm, kureba 260mm, kupatsanura 620mm;pasi ndiro ukobvu 10mm, longitudinal U-yakaumbwa stiffeners;Kukora kwedandemutande rakarerekera i14mm, ukobvu hwedandemutande repakati ndi9mm;nzvimbo yezvikamu zvakachinjika i4.0m, uye ukobvu i12mm;kureba kwedanda i2 ~ 3.5m.
Simbi bhokisi girder ichimiro chechimiro chinowanzo shandiswa muinjiniya.Kuti utarise pesvedzero yekupatsanurwa kweiyo inochinjika diaphragms pakukanganiswa kweiyo inongotsigirwa simbi bhokisi girder pasi pemutoro wakaomeswa, iyo yakapusa tsigiro simbi bhokisi girder ine nhamba dzakasiyana dzeyachinjika diaphragms yakaiswa kuti ienzanise yayo Distortion mhedzisiro uye yakasimba torsion mhedzisiro pasi pemutoro, iyo shanduko curve yeyakanyanya kukanganisa kukanganisa nenhamba yediaphragms inowanikwa.Yakaiswa mutoro inoiswa kumusoro kwebhokisi girder web, uye inogamuchirwa zvinoenderana neayo mana ekushanda mamiriro ekutsveyamisa, yakaoma torsion, symmetrical bending uye eccentric mutoro.Nzira yekuparara kwemutoro inoverengwa.
Zhenjiang Great Wall Heavy indasitiri ine anopfuura makumi mashanu matani emakrane, dhizaini yehunyanzvi, welding, uye zvikwata zvekuisa zvinogadzira uye kuisirwa matanda akasiyana ebhokisi resimbi.
Zvishandiso zvechigadzirwa
Nekuda kwechimiro chayo chechimiro, simbi yebhokisi girder inowanzoshandiswa kune yakasimudzwa uye ramp simbi bhokisi girder;kuvaka nguva traffic sangano refu-span cable-yakagara zambuko, kuturika zambuko, arch zambuko stiffening girder uye pedestrian zambuko simbi bhokisi girder.
