I-I-beam lilungu lesakhiwo kunye ne-cross-section e-I-shaped cross-section (efana ne-capital "I" ene-serifs) okanye i-H-shaped. Amanye amagama anxulumene zobugcisa abandakanya i-H-beam, i-I-section, ikholamu yendawo yonke (UC), i-W-beam (emele "i-flange ebanzi"), i-universal beam (UB), i-joist yensimbi edibeneyo (RSJ), okanye i-double-T. Zenziwe ngetsimbi kwaye zingasetyenziselwa kwizicelo ezahlukeneyo zokwakha.
Ngezantsi, makhe sithelekise umahluko phakathi kwe-H-beam kunye ne-I-beam ukusuka kumbono we-cross-sectional. Usetyenziso lwe-H-beam
I-H-beam isetyenziswa ngokuqhelekileyo kwiiprojekthi ezifuna ubude obude kunye nomthamo ophezulu wokuthwala umthwalo, njengamabhuloho kunye nezakhiwo eziphakamileyo.
H Beam Vs I Beam
Insimbi yeyona nto iguquguqukayo, isetyenziswa rhoqo ngezinto zokwakha. Bobabini i-H Beam kunye ne-I Beam zizinto eziqhelekileyo eziqhelekileyo ezisetyenziselwa ukwakhiwa kwezakhiwo zorhwebo.
Zombini ziyafana ngobume kubantu abaqhelekileyo, kodwa kukho umahluko omkhulu phakathi kwezi zimbini, ezibalulekileyo ukuba wazi.
Indawo ethe tyaba yayo yomibini imiqadi i-H kunye no-I ibizwa ngokuba ziiflanges, ngelixa indawo ethe nkqo isaziwa ngokuba yi "web." Iwebhu inceda ukuthwala amandla okucheba, ngelixa iiflange ziyilelwe ukuba zimelane nomzuzu wokugoba.
Ndiyintoni, Beam?
Iyinxalenye yesakhiwo ukuba imilo efana nenkunzi I. Iqukethe iiflange ezimbini ezidityaniswe yiwebhu. Umphezulu wangaphakathi wazo zombini iiflange une-slop, ngokuqhelekileyo, 1: 6, ezenza zibe ngqindilili ngaphakathi kwaye zincinci ngaphandle.
Ngenxa yoko, iqhuba kakuhle ekuthwaleni umthwalo phantsi koxinzelelo oluthe ngqo. Lo mqadi unemiphetho ecekethekileyo kunye nobude obuphezulu becandelo elinqamlezayo xa kuthelekiswa nobubanzi beflange.
Ngokusekelwe ekusebenziseni, amacandelo e-I-beam afumaneka kuluhlu lobunzulu, ubukhulu bewebhu, ububanzi be-flange, ubunzima, kunye namacandelo.
Yintoni i-H Beam?
Ikwalilungu lolwakhiwo elenziwe njengekomkhulu H eliquka intsimbi eqengqelekayo. Imiqadi yecandelo le-H isetyenziswa ngokubanzi kwizakhiwo zorhwebo kunye neendawo zokuhlala ngenxa yomlinganiselo wamandla obunzima kunye nezakhiwo eziphezulu zemishini.
Ngokungafaniyo nomqadi we-I, iiflange ze-H azinanto yangaphakathi, zenza inkqubo yokuwelda ibe lula. Zombini iiflange zinobukhulu obulinganayo kwaye zihambelana enye kwenye.
Iimpawu zayo ezinqamlezayo zingcono kune-beam ye-I, kwaye ineempawu ezingcono zoomatshini ngeyunithi nganye yobunzima obugcina izinto kunye neendleko.
Yeyona nto ithandwayo yamaqonga, i-mezzanines, kunye neebhulorho.
Ukuqala ukujonga, zombini i-H-icandelo kunye ne-I-icandelo lentsimbi yentsimbi ibonakala ifana, kodwa ezinye iiyantlukwano ezibalulekileyo phakathi kwezi zimbini zentsimbi ziyimfuneko ukwazi.
Ubume
Umqadi u-h ufana nokumila kwe-Capital H, ngelixa i-I beam iyimilo ye-Capital I.
Ukwenziwa kwemveliso
Imiqadi ye-I yenziwe ibe sisiqwenga esinye kulo lonke, ngelixa i-H-beam ibandakanya iipleyiti zentsimbi ezintathu ezidityanisiweyo.
Imiqadi ye-H inokwenziwa kuyo nayiphi na isayizi efunwayo, ngelixa umthamo womatshini wokusila unciphisa ukuveliswa kwee-I-beams.
Iiflange
I-H beam flanges inobunzima obulinganayo kwaye iyahambelana enye kwenye, ngelixa i-beam ine-tapered flanges ngokuthambekela kwe-1: ukuya ku-1:10 kumthamo ongcono wokuthwala umthwalo.
Ukutyeba kweWebhu
Umqadi we-h unewebhu engqindilili ngokuphawulekayo xa kuthelekiswa nomqadi we-I.
Inani lamaqhekeza
Umqadi wecandelo le-h ufana nentsimbi enye, kodwa ine-bevel apho iipleyiti ezintathu zetsimbi zidibene kunye.
Nangona i-beam yecandelo le-I ayiveliswanga nge-welding okanye i-riveting sheet sheets kunye, licandelo elinye kuphela lesinyithi ngokupheleleyo.
Ubunzima
Imiqadi H inzima ngobunzima xa ithelekiswa nemitha ye-I.
Umgama ukusuka ekupheleni kweFlange ukuya kwiziko leWebhu
Kwicandelo le-I, umgama ukusuka ekupheleni kwe-flange ukuya kwiziko leWebhu lincinci, ngelixa li-H-icandelo, Umgama ukusuka ekupheleni kwe-flange ukuya kwiziko lewebhu liphezulu kwicandelo elifanayo le-I-beam.
Amandla
I-beam yecandelo le-h inika amandla amaninzi ngeyunithi nganye ngenxa yendawo enqamlezileyo elungiselelwe ngakumbi kunye nomlinganiselo obalaseleyo wamandla-to-ubunzima.
Ngokubanzi, imiqadi yecandelo le-I inzulu kunobubanzi, nto leyo eyenza ukuba ilunge kakhulu ekuthwaleni umthwalo phantsi kwebuckling yendawo. Ngapha koko, zikhaphukhaphu ngobunzima kuneentsimbi zecandelo le-H, ngoko ke aziyi kuthatha umthwalo obalulekileyo njengeemitha ze-H.
Ukuqina
Ngokubanzi, imiqadi yecandelo le-H iqinile kwaye inokuthatha umthwalo onzima kuneentsimbi zecandelo le-I.
Indawo yokudlula
I-beam yecandelo le-I inecandelo elinqamlezayo elimxinwa elilungele ukuthwala umthwalo othe ngqo kunye noxinzelelo lwe-tensile kodwa ihlwempuzekile ekujikeni.
Xa kuthelekiswa, umqadi we-H unomnqamlezo obanzi kunomqadi we-I, onokuthwala umthwalo othe ngqo kunye noxinzelelo lwe-tensile kwaye uxhathise ukujija.
Ukulula kweWelding
Imiqadi yecandelo le-H ifikeleleka ngakumbi kwi-weld ngenxa yeeflange zazo zangaphandle ezithe tye kuneentsimbi zecandelo le-I. I-H-icandelo le-beam cross-section yomelele ngakumbi kune-I-section beam cross-section; kungoko inokuthatha umthwalo obaluleke ngakumbi.
Umzuzu we-Inertia
Umzuzu we-inertia yomqadi umisela amandla ayo okuxhathisa ukugoba. Okuphezulu kuya kuba, ngaphantsi kwe-beam iya kugoba.
Imiqadi yecandelo le-H ineeflange ezibanzi, ukuqina kwecala eliphakamileyo, kunye nomzuzu omkhulu we-inertia kunemiqadi yecandelo le-I, kwaye iyaxhathisa ngakumbi ekugobeni kunemiqadi yam.
Iispans
I-beam yecandelo le-I ingasetyenziselwa ubude beenyawo ukuya kwi-33 ukuya kwii-100 ngenxa yokunciphisa ukuveliswa, ngelixa i-H-section beam ingasetyenziselwa isithuba esingangeenyawo ze-330 ekubeni inokwenziwa kuyo nayiphi na isayizi okanye ukuphakama.
Uqoqosho
I-beam yecandelo le-H licandelo elinoqoqosho ngakumbi kunye nokuphucula izakhiwo zemishini kune-I-section beam.
Isicelo
Imiqadi yecandelo le-H ilungele i-mezzanines, iibhulorho, amaqonga, kunye nokwakhiwa kwezakhiwo eziqhelekileyo zokuhlala kunye nezorhwebo. Zikwasetyenziselwa ikholomu ethwele umthwalo, inqwelo erhuqwayo, kunye nefreyim yebhedi yelori.
Imiqadi yecandelo le-I licandelo elamkelweyo leebhulorho, izakhiwo zentsimbi yesakhiwo, kunye nokwenza izakhelo zenkxaso kunye neekholamu zee-elevators, ii-hoists kunye ne-lifts, i-trolleyways, ii-trailers, kunye neebhedi zelori.
