Intshayelelo emfutshane ye-I-beam:
I-I-beam, eyaziwa ngokuba yintsimbi yentsimbi (igama lesiNgesi elithi I Beam), ngumcu wentsimbi kunye necandelo elibunjwe ngu-I.I-beam yahlulwe ibe yi-I-beam eqhelekileyo kunye nekhaphukhaphu, i-H - intsimbi enemilo emithathu.I-I-beam isetyenziswa ngokubanzi kwizakhiwo ezahlukeneyo zokwakha, i-atlas Bridges, izithuthi, inkxaso, oomatshini kunye nokunye.Oqhelekileyo I-beam kunye nokukhanya I-beam iphiko ingcambu kancinci kancinci ukuya emphethweni, kukho iAngle ethile, eqhelekileyo I-beam kunye nokukhanya I-beam uhlobo imelwe linani leesentimitha ukuphakama esinqeni Arabic inombolo, web, flange. Ubukhulu kunye nobubanzi be-flange yeenkcukacha ezahlukeneyo kubude besinqe (h)× ububanzi bomlenze (b)× ubukhulu besinqe (d).Ukucaciswa kwe-I-beam eqhelekileyo kunokubonakaliswa ngumzekelo, imodeli ibonisa inani leesentimitha zokuphakama kwesinqe, njenge-16 # ngokubanzi.Ukuba kukho ububanzi bomlenze ohlukeneyo kunye nobukhulu besinqe se-I-miqadi enobude obufanayo esinqeni, i-A, B, kunye no-C kufuneka yongezwe kwicala lasekunene lomzekelo ukuzehlula.
Ukusetyenziswa kwe-I-beam:
I-I-beam eqhelekileyo, i-I-beam ekhanyayo, ngenxa yokuba ubungakanani becandelo buphezulu, buncinci, ngoko ke umzuzu we-inertia yemikhono emibini yecandelo inkulu kakhulu, ngoko ke, ngokubanzi inokusetyenziswa kuphela ngokuthe ngqo kwi-web plane ukugoba. amalungu okanye ukwakhiwa kweletiyisi yamalungu omkhosi.Akufanelekanga ukusebenzisa amalungu e-axial compression okanye ukugoba amalungu e-perpendicular kwi-plane yewebhu, eyenza ibe ncinane kakhulu kwi-scope yesicelo.
