Isiko I-beam
Inkcazelo emfutshane:
I-beam ikakhulu yahlulwe eqhelekileyo I-beam, ukukhanya I-beam kunye flange ububanzi I-beam.Ngokomlinganiselo wobude be-flange kwiwebhu, yahlulwe ibe yi-I-beams ebanzi, ephakathi kunye nemxinwa ye-flange.Iimpawu ezimbini zokuqala ziyi-10-60, oko kukuthi, ukuphakama okuhambelanayo ngu-10 cm-60 cm.Ekuphakameni okufanayo, ukukhanya kwe-I-beam kune-flange encinci, iwebhu encinci kunye nobunzima obulula.I-wide flange I-beam, eyaziwa ngokuba yi-H-beam, ibonakala ngemilenze emibini ehambelanayo kwaye akukho tyekelo kwicala langaphakathi lemilenze.Iyinxalenye yentsimbi yecandelo loqoqosho kwaye iqengqeleke kwimill emine ephezulu yendalo yonke, ngoko ikwabizwa ngokuba yi "universal I-beam".I-I-beam eqhelekileyo kunye ne-I-beam yokukhanya yenze imigangatho kazwelonke.
Iimpawu zesicelo
Ingaba intsimbi yecandelo le-I iqhelekile okanye ilula, kuba ubungakanani becandelo buphezulu kwaye bumxinwa, umzuzu we-inertia yee-axes ezimbini eziphambili zecandelo uhluke kakhulu, ngoko ke inokusetyenziswa ngokuthe ngqo kumalungu agobileyo kwinqwelomoya. iwebhu yabo okanye ifomu lattice wagxininisa amalungu.Ayifanelekanga kumalungu e-axial compression okanye amalungu ane-goba perpendicular kwi-plane yewebhu, eyenza ibe ncinane kakhulu kwi-scope yesicelo.I-I-beam isetyenziswa ngokubanzi kwizakhiwo okanye kwezinye izakhiwo zetsimbi.
Ngenxa yobukhulu obuphezulu kunye nobukhulu becandelo le-I-beam kunye nokukhanya kwe-I-beam, umzuzu we-inertia yee-axes eziphambili zecandelo uhluke kakhulu, okwenza kube nzima kakhulu kumda wesicelo.Ukusetyenziswa kwe-I-beam kuya kukhethwa ngokweemfuno zemizobo yoyilo.
Xa ukhetha i-I-beam kuyilo lwesakhiwo, i-I-beam efanelekileyo iya kukhethwa ngokwezinto zayo zomatshini, iikhemikhali, i-weldability kunye nobukhulu besakhiwo.
