I-I-beam iyilungu lesakhiwo eline-cross-section emise okwe-I (efana nohlamvu olukhulu "I" olunama-serif) noma olumise okwe-H. Amanye amagama obuchwepheshe ahlobene afaka phakathi i-H-beam, i-I-section, ikholomu ye-universal (UC), i-W-beam (emele "i-wide flange"), i-universal beam (UB), i-rolled steel joist (RSJ), noma i-double-T. Zenziwe ngensimbi futhi zingasetshenziswa ezinhlotsheni ezahlukene zokwakha.
Ngezansi, ake siqhathanise umehluko phakathi kwe-H-beam kanye ne-I-beam ngombono wesigaba esiphambene.
I-H-beam ivame ukusetshenziswa kumaphrojekthi adinga ubude obude kanye nomthamo ophezulu wokuthwala imithwalo, njengamabhuloho nezakhiwo eziphakeme.
I-H Beam Vs I Beam
Insimbi iyinto yokwakha eguquguqukayo kakhulu, esetshenziswa njalo. Zombili i-H Beam kanye ne-I Beam yizinto zokwakha ezivame kakhulu ezisetshenziswa ekwakheni izakhiwo zezentengiselwano.
Zombili ziyafana ngesimo kubantu abavamile, kodwa kukhona umehluko omkhulu phakathi kwalezi ezimbili, okubalulekile ukuzazi.
Ingxenye evundlile yemisebe ye-H ne-I ibizwa ngokuthi ama-flange, kuyilapho ingxenye evundlile yaziwa ngokuthi “iwebhu.” Iwebhu isiza ukuthwala amandla okusika, kuyilapho ama-flange eklanyelwe ukumelana nesikhathi sokugoba.
Ngingubani mina, Beam?
Kuyingxenye yesakhiwo enomumo ofana nohlamvu olukhulu I. Yakhiwa ama-flange amabili axhunywe yiwebhu. Ubuso bangaphakathi bama-flange womabili bunomugqa, ngokuvamile, ongu-1:6, okwenza abe mancane ngaphakathi nangaphandle abe mancane.
Ngenxa yalokho, isebenza kahle lapho ithwala umthwalo ngaphansi kwengcindezi eqondile. Lo msebe unemiphetho enciphile kanye nokuphakama okuphezulu kwesigaba esiphambene uma kuqhathaniswa nobubanzi beflange.
Ngokusekelwe ekusetshenzisweni, izingxenye ze-I-beam zitholakala ngobubanzi bokujula, ubukhulu bewebhu, ububanzi be-flange, isisindo, kanye nezingxenye.
Kuyini i-H Beam?
Futhi iyilungu lesakhiwo elibunjwe njengo-H omkhulu owakhiwe ngensimbi egoqiwe. Imishayo yesigaba se-H isetshenziswa kabanzi ezakhiweni zezentengiselwano nezindawo zokuhlala ngenxa yesilinganiso sazo samandla nesisindo kanye nezakhiwo zazo zemishini eziphakeme.
Ngokungafani nomqadi we-I, ama-flange e-H beam awanayo i-inside intensity, okwenza inqubo yokushisela ibe lula. Womabili ama-flange anobukhulu obulinganayo futhi ahambisana.
Izici zayo ezihlanganisa izingxenye zingcono kune-I beam, futhi inezakhiwo ezingcono zomshini ngesisindo seyunithi ngayinye ezisindisa izinto kanye nezindleko.
Yinto ethandwa kakhulu ngamapulatifomu, ama-mezzanine, namabhuloho.
Ekuqaleni, imishayo yensimbi yesigaba se-H kanye nesigaba se-I ibukeka ifana, kodwa umehluko obalulekile phakathi kwale mishayo yensimbi emibili kubalulekile ukwazi.
Isimo
Umsebe we-h ufana nesimo se-Capital H, kanti umsebe we-I ufana nesimo se-Capital I.
Ukukhiqiza
Imishayo ye-I yenziwa njengento eyodwa kuyo yonke indawo, kuyilapho i-H-beam inamapuleti amathathu ensimbi ahlanganiswe ndawonye.
Imisebe ye-H ingakhiwa nganoma yisiphi isayizi esifunwayo, kuyilapho amandla omshini wokugaya ekhawulela ukukhiqizwa kwemisebe ye-I.
Ama-Flanges
Ama-flange e-H beam anobukhulu obulinganayo futhi ahambisana, kuyilapho i-I beam inama-flange anciphile anokuthambekela okungu-1: kuya ku-1:10 ukuze kube nomthamo ongcono wokuthwala umthwalo.
Ubukhulu bewebhu
Umsebe we-h unewebhu ejiyile kakhulu uma kuqhathaniswa nomsebe we-I.
Inani lezingcezu
Ugongolo lwe-h-section lufana nengxenye eyodwa yensimbi, kodwa lune-bevel lapho amapuleti ensimbi amathathu ehlanganiswa khona.
Nakuba ugongolo lwe-I-section lungakhiqizwa ngokuhlanganisa amashidi ensimbi noma ngokuwahlanganisa ndawonye, luyingxenye eyodwa kuphela yensimbi ngokuphelele.
Isisindo
Imisebe ye-H inzima kakhulu uma iqhathaniswa nemisebe ye-I.
Ibanga Ukusuka Ekugcineni Kwe-Flange Kuya Esikhungweni Sewebhu
Esigabeni se-I, ibanga ukusuka ekugcineni kwe-flange ukuya enkabeni yeWebhu lincane, kanti esigabeni se-H, ibanga ukusuka ekugcineni kwe-flange ukuya enkabeni yeWebhu liphakeme esigabeni esifanayo se-I-beam.
Amandla
Ugongolo lwesigaba se-h lunikeza amandla engeziwe ngesisindo seyunithi ngayinye ngenxa yendawo ehlanganisiwe eyenziwe ngcono kakhulu kanye nesilinganiso esihle kakhulu samandla nesisindo.
Ngokuvamile, imishayo yesigaba se-I ijule kakhulu kunobubanzi, okwenza ibe mihle kakhulu ekuthwaleni umthwalo ngaphansi kwe-buckling yendawo. Ngaphezu kwalokho, ilula ngesisindo kunemishayo yesigaba se-H, ngakho ngeke ithwale umthwalo omkhulu njengemishayo ye-H.
Ukuqina
Ngokuvamile, imishayo yesigaba se-H iqinile kakhulu futhi ingathwala umthwalo osindayo kunemishayo yesigaba se-I.
Isigaba esiphambanayo
Umsebe wesigaba se-I unesigaba esincane esifanelekile ukuthwala umthwalo oqondile kanye nokucindezeleka kokudonsa kodwa awulungele ukusonteka.
Uma kuqhathaniswa, umsebe we-H unesigaba esibanzi kune-I beam, esingaphatha umthwalo oqondile kanye nokucindezeleka kokudonsa futhi simelane nokusonteka.
Ukushelela Kalula
Imishayo yesigaba se-H ifinyeleleka kalula ekushiseleni ngenxa yama-flange ayo angaphandle aqondile kunemishayo yesigaba se-I. Imishayo yesigaba se-H iqine kakhulu kunemishayo yesigaba se-I; ngakho-ke ingathwala umthwalo omkhulu.
Isikhathi Sokungabi Naso
Isikhathi Sokungakwazi Kwesigqi senduku sinquma ikhono layo lokumelana nokugoba. Uma iphakeme, yilapho induku izogoba kancane.
Imishayo yesigaba se-H inezingqimba ezibanzi, ukuqina okuphezulu kwezinhlangothi, kanye nesikhathi esiningi sokungaguquguquki kunemishayo yesigaba se-I, futhi imelana kakhulu nokugoba kunemishayo yesigaba se-I.
Ama-Span
Ugongolo lwesigaba se-I lungasetshenziswa isikhathi esingafika kumamitha angu-33 kuya kwangu-100 ngenxa yemikhawulo yokukhiqiza, kanti ugongolo lwesigaba se-H lungasetshenziswa isikhathi esingafika kumamitha angu-330 ngoba lungenziwa nganoma yisiphi isayizi noma ukuphakama.
Umnotho
Umsebe wesigaba se-H uyisigaba esingabizi kakhulu esinezakhiwo ezithuthukisayo zemishini kunemsebe wesigaba se-I.
Isicelo
Imishayo yesigaba se-H ilungele ama-mezzanine, amabhuloho, amapulatifomu, kanye nokwakhiwa kwezakhiwo ezivamile zokuhlala nezebhizinisi. Zisetshenziselwa futhi uhlaka lwekholomu ethwala imithwalo, i-trailer, kanye nombhede weloli.
Imishayo yesigaba se-I yisigaba esamukelwe samabhuloho, izakhiwo zensimbi ezakhiwe, kanye nokwenziwa kohlaka lokusekela kanye nezinsika zama-lifti, ama-hoist nama-lifti, imigwaqo yama-trolley, ama-trailer, kanye nemibhede yamaloli.
