I-I-beam iyilungu lesakhiwo elinesiphambano esimise oku-I (elifana nenhloko-dolobha ethi "I" enama-serif) noma okumise okuka-H. Amanye amatemu obuchwepheshe ahlobene ahlanganisa i-H-beam, i-I-section, ikholomu yendawo yonke (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 ezinhlobonhlobo zezicelo zokwakha.
Ngezansi, ake siqhathanise umehluko phakathi kwe-H-beam ne-I-beam ngokombono wesigaba esiphambene. Izicelo ze-H-beam
I-H-beam ivame ukusetshenziswa kumaphrojekthi adinga izikhala ezinde namandla okuthwala umthwalo, njengamabhuloho nezakhiwo eziphakeme.
H Beam Vs I Beam
Insimbi iyona nto yesakhiwo evumelana nezimo kakhulu, esetshenziswa njalo. Kokubili i-H Beam kanye ne-I Beam yizinto ezivamile zesakhiwo ezisetshenziswa ekwakhiweni kwezakhiwo zentengiso.
Zombili ziyafana ngesimo kubantu abajwayelekile, kepha kunomehluko omkhulu phakathi kwalokhu okubili, okubalulekile ukwazi.
Ingxenye evundlile yayo yomibili imishayo engu-H no-I ibizwa ngokuthi ama-flange, kuyilapho ingxenye eqondile yaziwa ngokuthi “iwebhu.” Iwebhu isiza ukuthwala amandla okugunda, kuyilapho ama-flange enzelwe ukumelana nomzuzu wokugoba.
Ngiyini mina, Beam?
Kuyingxenye yesakhiwo ukuthi umumo ofana nosonhlamvukazi I. Uqukethe ama-flange amabili axhunywe iwebhu. Ingaphakathi lawo womabili ama-flange ane-slop, ngokuvamile, u-1:6, okuwenza abe mkhulu ngaphakathi futhi abe mncane ngaphandle.
Ngenxa yalokho, yenza kahle ekuthwaleni umthwalo ngaphansi kwengcindezi eqondile. Le nsimbi inemiphetho ecijile nobude obuphakeme besigaba esiphambene uma kuqhathaniswa nobubanzi be-flange.
Ngokusekelwe ekusetshenzisweni, izigaba ze-I-beam zitholakala kuhlu lokujula, ukujiya kwewebhu, ububanzi be-flange, izisindo, nezigaba.
Yini i-H Beam?
Futhi iyilungu lesakhiwo elimise okwenhlokodolobha H ehlanganisa insimbi egoqiwe. Imishayo ye-H-section isetshenziswa kakhulu ezakhiweni zezentengiselwano nezindawo zokuhlala ngenxa yesilinganiso sazo samandla nesisindo kanye nezakhiwo eziphakeme zemishini.
Ngokungafani ne-I beam, ama-H beam flanges awanakho ukuthambekela kwangaphakathi, okwenza inqubo yokushisela ibe lula. Womabili ama-flange anogqinsi olulinganayo futhi ayahambisana.
Izici zayo eziphambanayo zingcono kune-I beam, futhi inezakhiwo ezingcono zemishini ngeyunithi ngayinye yesisindo ezonga impahla nezindleko.
Iwumsebenzi othandwayo wamapulatifomu, ama-mezzanines, namabhuloho.
Ekubukeni kokuqala, kokubili imishayo yensimbi ye-H-section kanye ne-I-section ibukeka ifana, kodwa umehluko obalulekile phakathi kwalezi zingongolo ezimbili zensimbi kubalulekile ukwazi.
Isimo
Uthango luka-h lufana nokuma kwe-Capital H, kuyilapho i-I beam iwumumo we-Capital I.
Ukukhiqiza
I-I-imishayo ikhiqizwa njengesiqephu esisodwa kulo lonke, kuyilapho i-H-beam iqukethe amapuleti ensimbi amathathu ashiselwe ndawonye.
Imishayo ye-H ingenziwa kunoma yimuphi usayizi oyifunayo, kuyilapho amandla omshini wokugaya akhawulela ukukhiqizwa kwe-I-imishayo.
Ama-Flanges
Ama-flange we-H anogqinsi olulinganayo futhi ayahambisana, kuyilapho mina nginama-flanges acijile ngokuthambekela koku-1: kuya ku-1:10 ukuze uthole umthamo ongcono wokuthwala umthwalo.
Ubukhulu bewebhu
I-h beam inewebhu ewugqinsi ngokuphawulekayo uma iqhathaniswa ne-I beam.
Inombolo yezingcezu
I-beam yesigaba sika-h ifana nensimbi eyodwa, kodwa ine-bevel lapho amapuleti ensimbi amathathu ashiselwa ndawonye.
Nakuba i-I-section beam ayikhiqizwa ngokushisela noma ngokuhlanganisa amashidi ensimbi, iyingxenye eyodwa kuphela yensimbi.
Isisindo
Imishayo engu-H isindayo ngesisindo uma iqhathaniswa nemishayo ye-I.
Ibanga Kusukela ekupheleni Flange Kuya esikhungweni Web sika
Esigabeni se-I, ibanga ukusuka ekugcineni kwe-flange kuya esikhungweni seWebhu lincane, kuyilapho esigabeni H, Ibanga elisuka ekugcineni kwe-flange kuya esikhungweni seWebhu liphakeme ngesigaba esifanayo se-I-beam.
Amandla
I-beam yesigaba sika-h inika amandla engeziwe ngeyunithi ngayinye yesisindo ngenxa yendawo ethuthukisiwe ye-cross-sectional kanye nesilinganiso esihle kakhulu samandla nesisindo.
Ngokuvamile, imishayo ye-I-section ijulile kunobubanzi, okuyenza ibe yinhle kakhulu ekuthwaleni umthwalo ngaphansi kokubopha kwasendaweni. Ngaphezu kwalokho, anesisindo esincane kunemishayo yesigaba sika-H, ngakho-ke ngeke athathe umthwalo obalulekile njengama-H-beam.
Ukuqina
Ngokuvamile, imishayo ye-H-section iqinile futhi ingathatha umthwalo osindayo kunemishayo ye-I-section.
Isigaba esiphambanayo
I-beam ye-I-section ine-cross-section ewumngcingo efanele ukuthwala umthwalo oqondile kanye nezingcindezi eziqinile kodwa ayilungile uma iphikisana.
Uma kuqhathaniswa, i-H ine-cross-section ebanzi kune-I beam, engakwazi ukuphatha umthwalo oqondile kanye nezingcindezi eziqinile futhi imelane nokusonteka.
Kalula Welding
Imishayo ye-H-section ifinyeleleka kalula ekushiseleni ngenxa yama-flange ayo angaphandle aqondile kunemishayo ye-I-section. Isigaba esiphambanayo sobhongo sesigaba sika-H siqine kakhulu kunesiphambano se-I-section ye-beam; ngakho-ke kungathatha umthwalo obaluleke kakhulu.
Isikhathi se-Inertia
I-Moment of Inertia ye-beam inquma amandla ayo okumelana nokugoba. Lapho kuzoba phezulu, ugongolo luzogoba kancane.
Imishayo yesigaba sika-H inama-flange abanzi, ukuqina kwe-lateral okuphezulu, kanye nomzuzu omkhulu we-inertia kunemishayo ye-I-section, futhi imelana kakhulu nokugoba kunemishayo yami.
Izipani
I-I-section beam ingasetshenziselwa ibanga elingafika ku-33 kuya ku-100 izinyawo ngenxa yemikhawulo yokukhiqiza, kuyilapho i-H-section beam ingasetshenziswa isikhathi esingafika ku-330 amafidi njengoba ingenziwa kunoma yimuphi usayizi noma ukuphakama.
Umnotho
I-beam yesigaba H yisigaba esonga kakhulu esinezakhiwo ezithuthukisiwe zemishini kune-I-section beam.
Isicelo
Imishayo yesigaba sika-H ilungele ama-mezzanines, amabhuloho, izinkundla, nokwakhiwa kwezakhiwo ezijwayelekile zokuhlala nezohwebo. Zibuye zisetshenziselwe ikholomu ethwala umthwalo, i-trailer, nohlaka lombhede wamaloli.
Imishayo ye-I-section ingxenye eyamukelwayo yamabhuloho, izakhiwo zensimbi yesakhiwo, kanye nokwenza amafreyimu asekelayo namakholomu amakheshi, ama-hoist namakheshi, ama-trolleyways, ama-trailer, nemibhede yamaloli.
