I-beam yangokwezifiso
Incazelo emfushane:
I-I-beam ihlukaniswe ikakhulukazi i-I-beam evamile, i-I-beam elula kanye ne-wide flange I-beam.Ngokwesilinganiso sobude be-flange kuya kuwebhu, ihlukaniswe yaba imishayo ye-flange ebanzi, ephakathi nendawo emincane.Izincazelo ezimbili zokuqala ziyi-10-60, okungukuthi, ukuphakama okuhambisanayo ku-10 cm-60 cm.Ekuphakameni okufanayo, ukukhanya kwe-I-beam kune-flange encane, iwebhu encane nesisindo esincane.I-wide flange I-beam, eyaziwa nangokuthi i-H-beam, ibonakala ngemilenze emibili ehambisanayo futhi akukho ukuthambekela ohlangothini lwangaphakathi lwemilenze.Iyingxenye yensimbi yesigaba sezomnotho futhi igoqelwa kumshini wokugaya ophakeme we-universal high, ngakho ibizwa nangokuthi "i-universal I-beam".I-I-beam evamile kanye ne-I-beam ekhanyayo yakhe izindinganiso zikazwelonke.
Izici zohlelo lokusebenza
Kungakhathaliseki ukuthi insimbi ye-I-section ijwayelekile noma ilula, ngenxa yokuthi usayizi wesigaba uphakeme futhi uncane, isikhathi sokungenzi lutho kwezimbazo ezimbili eziyinhloko zesigaba sihluke kakhulu, ngakho singasetshenziswa kuphela ngokuqondile kumalungu agobile endizeni iwebhu yabo noma amalungu e-lattice agcizelelwe.Ayilungele amalungu e-axial compression noma amalungu ane-gonding perpendicular endizeni yewebhu, okwenza ibe nomkhawulo kakhulu kububanzi bohlelo lokusebenza.I-i-beam isetshenziswa kabanzi ezakhiweni noma kwezinye izakhiwo zensimbi.
Ngenxa yosayizi wesigaba ophakeme futhi omncane we-I-beam evamile kanye ne-I-beam ekhanyayo, isikhathi sokungashintshi kwezimbazo ezimbili eziyinhloko zesigaba sihluke kakhulu, okwenza kube nomkhawulo kakhulu kububanzi bohlelo lokusebenza.Ukusetshenziswa kwe-I-beam kuzokhethwa ngokuya ngezidingo zemidwebo yokuklama.
Lapho ukhetha i-I-beam ekwakhiweni kwesakhiwo, i-I-beam enengqondo izokhethwa ngokuya ngezakhiwo zayo zemishini, izakhiwo zamakhemikhali, ukushisela kanye nosayizi wesakhiwo.
