I-I-beam ekhanyayo
I-I-imishayo ihlukaniswe ngokuyinhloko ibe i-I-imishayo evamile, i-light-duty I-imishayo kanye ne-wide-flange I-imishayo. Ngokwesilinganiso sobude be-flange kuwebhu, ihlukaniswe yaba imishayo ye-I-flange ebanzi, ephakathi, futhi emincane ebanzi. Izincazelo ezimbili zokuqala zokukhiqiza ziyi-10-60, okungukuthi, ukuphakama okuhambisanayo kungu-10 cm-60 cm. Ekuphakameni okufanayo, i-I-beam engasindi inama-flange amancane, ama-webs amancane nesisindo esincane. I-wide-flange I-beam ibizwa nangokuthi i-H-beam, futhi isigaba sayo esiphambanayo sibonakala ngemilenze ehambisanayo futhi akukho mthambeko ohlangothini lwangaphakathi lwemilenze. Iyingxenye yensimbi yesigaba sezomnotho, egoqwe esigayweni esiginqikayo esiphezulu esine-universal, ngakho-ke ibizwa nangokuthi "i-universal I-beam". Ama-I-beams ajwayelekile kanye ne-light-duty I-beams abe yizindinganiso zikazwelonke.
Kungakhathaliseki ukuthi insimbi emise okwe-I ijwayelekile noma ilula, ngoba usayizi wesigaba esiphambanayo uphakeme futhi uncane, umzuzu we-inertia yezimbazo ezimbili eziyinhloko ze-cross-section uhluke kakhulu, ngakho-ke ungasetshenziswa ngokuqondile. ngokugoba endizeni yewebhu yayo. Izingxenye noma zizenze zibe izingxenye ezithwala amandla ohlobo lwe-lattice. Akufanelekile ukusebenzisa izingxenye zokucindezela kwe-axial noma izingxenye ezincikene nendiza yewebhu, nayo egobile, okwenza ububanzi bayo bokusebenza bube buncane kakhulu. I-I-imishayo isetshenziswa kabanzi ekwakheni noma kwezinye izakhiwo zensimbi.
Ama-I-beams ajwayelekile kanye nama-I-duty-duty-lights aneziphambano eziphakeme ngokuqhathaniswa neziwumngcingo, ngakho-ke izikhathi ze-inertia yezimbazo ezimbili eziyinhloko zezigaba eziphambene zihluke kakhulu, ezikhawulela ububanzi bokusebenza kwazo. Ukusetshenziswa kwe-I-beam kufanele kukhethwe ngokuvumelana nezidingo zemidwebo yokuklama.
Ukukhethwa kwe-I-beam ekwakhiweni kwesakhiwo kufanele kusekelwe emikhiqizweni yayo, izakhiwo zamakhemikhali, ukushisela, usayizi wesakhiwo, njll. ukukhetha i-I-beam efanelekile ukuze isetshenziswe.
