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". I-I-beams eqhelekileyo kunye ne-light-duty I-beams ibe yimigangatho yelizwe.
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, i-weldability, ubukhulu besakhiwo, njl.njl ukukhetha i-I-beam efanelekileyo yokusetyenziswa.
