Imininingwane Yomkhiqizo

Omaka bomkhiqizo

isingeniso somkhiqizo

Ibhande lebhokisi lensimbi lakhiwe ngepuleti eliphezulu, ipuleti elingaphansi, iwebhu, ukwahlukanisa okuphambene kanye neziqiniseko ze-longitudinal nezinqamulayo. Izinhlobo zayo ezivame ukusetshenziswa eziphambanayo zihlanganisa ibhokisi elilodwa igumbi elilodwa, ibhokisi elilodwa amagumbi amathathu, ibhokisi eliphindwe kabili igumbi elilodwa, amabhokisi amathathu, igumbi elilodwa lebhokisi elilodwa, i-Multi-box single-chamber, i-trapezoid ehlanekezelwe enowebhu ethambekele, i-single-box multi-chamber enezinto ezingaphezu kwe Ama-web angu-3, ​​ibhande lebhokisi lensimbi eliyisicaba, njll. Phakathi kwazo, ingxenye yebhande lebhokisi lensimbi esetshenziswa kakhulu yi-double-box single-chamber, futhi i-multi-box single-chamber isetshenziselwa amabhuloho anobubanzi obukhulu bebhuloho. Ibhande lebhokisi lensimbi eliyisicaba linesilinganiso esincane sobude be-beam ukuya kububanzi be-beam, futhi lisetshenziselwa ikakhulukazi imishayo enezimbambo njengamabhuloho amisiwe, amabhuloho ahlala ngekhebula, namabhuloho amakhothamo. Akuvamile ukusetshenziswa emabhulohweni e-beam. Ibhokisi elilodwa lebhokisi lensimbi elinama-web angaphezu kuka-3 akulula ukulikhiqiza nokulifaka, ngakho-ke alivamile ukusetshenziswa.

Ibhuloho le-Multiple Box Girder (1)

Ihlukaniswe ngezigaba eziningana zemishayo yokukhiqiza nokufakwa, futhi ingxenye yayo yesiphambano inezici zomumo obanzi nesicaba, futhi isilinganiso se-aspect ratio sifinyelela cishe ku-1:10. Ibhande lebhokisi lensimbi ngokuvamile lakhiwa ngokushisela ngokuphelele ipuleti eliphezulu, ipuleti elingaphansi, iwebhu, kanye nokuhlukanisa okuphambene, ama-partitions ama-longitudinal kanye neziqinisekiso. Ipuleti eliphezulu liyidekhi yebhuloho le-orthotropic elakhiwe ipuleti lekhava kanye nama-longitudinal stiffeners. Ubukhulu bepuleti ngalinye lebhande lensimbi elivamile kungaba: ukujiya kwekhava okungu-14mm, ukujiya kwezimbambo ezimise okwe-U ubude obungu-6mm, ububanzi bomlomo ongenhla buyi-320mm, ububanzi bomlomo ophansi bungu-170mm, ukuphakama bungu-260mm, isikhala esingu-620mm; ugqinsi lwepuleti elingaphansi 10mm, izigxivizo eziqinile ezimise okwe-U longitudinal; Ukuqina kwewebhu ethambekele kungu-14mm, ukujiya kwewebhu ephakathi kungu-9mm; ukuhlukaniswa kwama-partitions aguquguqukayo ngu-4.0m, kanti ukujiya kungu-12mm; ubude be-beam buyi-2 ~ 3.5m.

Izinzuzo zomkhiqizo

1. Isisindo esincane nokonga impahla
2. Ukugoba kanye nokuqina kwe-torsion kukhulu
3. Ukufakwa okulula, izindleko eziphansi, umjikelezo omfushane
4. Ikhwalithi eqinisekisiwe kanye nenani, nokuthembeka okuphezulu.
5. Ukusebenza kahle kokwakhiwa okuphezulu nokuphepha okuphezulu
6. Isetshenziswa kabanzi

Izinhlelo zokusebenza zomkhiqizo

Ngenxa yesakhiwo sawo, ibhande lebhokisi lensimbi livame ukusetshenziselwa ibhande lebhokisi lensimbi eliphakeme kanye ne-ramp; Inhlangano yethrafikhi yesikhathi sokwakha ibhuloho elinekhebula elihlala isikhathi eside, ibhuloho elimisiwe, ibhuloho eliyi-arch eliqinisa ibhande kanye nebhuloho labahamba ngezinyawo.
