I-H-beams I-beam I-Hot Rolled Iron Carbon Steel Idiphu Eshisayo efakwe uthayela

I-H-section steel iwuhlobo lwesigaba esinomnotho kanye nesigaba esisebenza kahle kakhulu esinokusabalalisa okuthuthukisiwe kwezingxenye ezihlukene kanye nesilinganiso esinengqondo kakhulu samandla nesisindo. Iqanjwe ngoba ingxenye yayo iyafana nohlamvu lwesiNgisi oluthi "H". Njengoba izingxenye ezihlukahlukene zensimbi emise okwe-H zihlelwe ngama-engeli alungile, insimbi emise okwe-H inezinzuzo zokumelana nokugoba okuqinile, ukwakhiwa okulula, ukonga izindleko kanye nesisindo sesakhiwo esilula kuzo zonke izinkomba, futhi iye yasetshenziswa kabanzi. Ugqinsi lwewebhu ye-H-beam buncane kunalolo lwe-I-beam evamile enobude obufanayo bewebhu, futhi ububanzi be-flange bukhulu kunobu-I-beam obujwayelekile obunobude obufanayo bewebhu, ngakho-ke ibizwa nangokuthi i-wide-edge I-beam. Kunqunywa ukuma, i-modulus yesigaba, umzuzu we-inertia namandla ahambisanayo we-H-imishayo kungcono kakhulu kune-I-imishayo evamile yesisindo esisodwa esisodwa. Isetshenziswa ezakhiweni zensimbi ezinezidingo ezahlukene, kungakhathaliseki ukuthi ithwala umzuzu wokugoba, umthwalo wengcindezi, noma umthwalo we-eccentric, ibonisa ukusebenza kwayo okuphezulu. Uma kuqhathaniswa ne-I-beam evamile, ingathuthukisa kakhulu umthamo wokuthwala futhi isindise insimbi ngo-10% -40%. Insimbi emise okwe-H inama-flange abanzi, amawebhu amancane, ukucaciswa okuningi, kanye nokusetshenziswa okuguquguqukayo. Ingonga u-15% kuya ku-20% wensimbi lapho isetshenziswa ezakhiweni ezihlukahlukene ze-truss. Ngenxa yokuthi ama-flange ahambisana ngaphakathi nangaphandle, futhi imiphetho isema-engeli alungile, kulula ukuhlanganisa nokuhlanganisa izingxenye ezihlukahlukene, ezingasindisa cishe u-25% womthwalo wokushisela kanye ne-riveting, ongasheshisa kakhulu isivinini sokwakha iphrojekthi futhi unciphise isikhathi sokwakha.
