Ukukhanya I-beam
I-I-beams ihlulwe ngokukodwa kwii-I-beams eziqhelekileyo, i-light-duty I-beams kunye ne-wide-flange I-beams.Ngokomphakamo we-flange kwiwebhu, yahlulwe ibe yi-I-beams ebanzi, ephakathi, kunye nemxinwa ebanzi ye-flange.Iimpawu ezimbini zokuqala zemveliso ziyi-10-60, oko kukuthi, ukuphakama okuhambelanayo ngu-10 cm-60 cm.Ekuphakameni okufanayo, i-I-beam ekhanyayo inama-flanges amancinci, ama-webs amancinci kunye nobunzima obulula.I-wide-flange I-beam ibizwa ngokuba yi-H-beam, kwaye i-cross-section yayo ibonakaliswe ngemilenze ehambelanayo kwaye akukho thambeka kwicala langaphakathi lemilenze.Iyinxalenye yentsimbi yecandelo loqoqosho, egqitywe kwi-four-high universal rolling mill, ngoko ikwabizwa ngokuba yi "universal I-beam".Iintsimbi eziqhelekileyo ze-I kunye ne-light-duty-duty-beams ziye zaba yimigangatho kazwelonke.
Kungakhathaliseki ukuba i-I-shaped iron iyinto eqhelekileyo okanye ilula, kuba ubukhulu becandelo elinqamlezayo liphezulu kwaye lincinci, umzuzu we-inertia yee-axes ezimbini eziphambili zecandelo lomnqamlezo uhluke kakhulu, ngoko unokusetyenziswa ngokuthe ngqo. ngokugoba kwinqwelomoya yewebhu yayo.Amacandelo okanye azenze zibe ngamacandelo athwala amandla ohlobo lweletisi.Akufanelekanga ukusebenzisa i-axial compression components okanye amacandelo axhomekeke kwi-plane yewebhu, ebuye igobe, eyenza ukuba usetyenziso lwayo lube luncinci kakhulu.I-I-beams isetyenziswa ngokubanzi ekwakheni okanye kwezinye izakhiwo zetsimbi.
I-I-beams eqhelekileyo kunye ne-light-duty-duty-beams ine-cross-sections ephezulu kunye nemxinwa, ngoko ke amaxesha e-inertia yee-axes eziphambili ze-cross-sections ahluke kakhulu, okunciphisa umda wesicelo sabo.Ukusetyenziswa kwe-I-beam kufuneka kukhethwe ngokweemfuno zemizobo yoyilo.
Ukukhethwa kwe-I-beam kwi-design yesakhiwo kufuneka kusekelwe kwiimpawu zayo zemishini, iikhemikhali zekhemikhali, i-weldability, ubukhulu besakhiwo, njl.
