I-Europe Ehlanzekile Ejwayelekile Eshisayo Ejikijelwe H Insimbi Yensimbi Eyi-Wide Flange Universal Beams UB Universal Columns UC

Insimbi ye-H-beam egoqwe ngokushisayo inama-flange abanzi kanye nokuqina okukhulu kwezinhlangothi;inokumelana nokugoba okuqinile, cishe ngo-5-10% kunensimbi ye-I-beam.Ama-flange amabili ayahambisana, futhi isakhiwo sifanelekile.

Ukucaciswa:

Izici:
Imishayo ye-H egoqelwe ngokushisayo isabalalisa ngokunengqondo isilinganiso sesici sosayizi wesigaba ngokwezinjongo ezihlukene, futhi ibe nezakhiwo ezinhle kakhulu zemishini nokusebenza okuphakeme kokusetshenziswa.

Amandla esakhiwo aphezulu.Uma kuqhathaniswa ne-I-beam, i-modulus yesigaba inkulu, futhi insimbi ingasindiswa ngo-10-15% ngaphansi kwezimo ezifanayo zokuthwala.
Isitayela sokuklama siyaguquguquka futhi sicebile.Endabeni yobude obufanayo be-beam, i-steel structure bay ingaba nkulu ngo-50% kune-concrete structure bay, ngaleyo ndlela yenza isakhiwo sesakhiwo sibe nezimo.
Isakhiwo silula.Uma kuqhathaniswa nesakhiwo sekhonkrithi, ilula kunesakhiwo sekhonkrithi, futhi isisindo sesakhiwo siqu siyancishiswa, okunciphisa amandla angaphakathi okwakhiwa kwesakhiwo, okungenza izidingo zokwelashwa kwesisekelo sesakhiwo esiphansi, ukwakhiwa okulula kanye nezindleko eziphansi.
Isakhiwo sensimbi ngokuyinhloko esenziwe ngensimbi ye-H-section eshisayo inesakhiwo sesayensi nesinengqondo, ipulasitiki enhle nokuguquguquka, kanye nokuzinza okuphezulu kwesakhiwo.Ifanele ukwakha izakhiwo ezimelana nokudlidliza okukhulu kanye nemithwalo yethonya.Inokumelana okuqinile nezinhlekelele zemvelo, futhi ifaneleka ngokukhethekile kwabaningi Isakhiwo sokwakha endaweni yokuzamazama komhlaba.Ngokwezibalo, ezinhlekeleleni zokuzamazama komhlaba ezibhubhisayo zomhlaba zesilinganiso esingu-7 noma ngaphezulu, izakhiwo zensimbi ezibuswa insimbi emise okwe-H ziye zalimala kakhulu.
Khulisa indawo esebenzayo yokusetshenziswa kwesakhiwo.Uma kuqhathaniswa nesakhiwo sikakhonkolo, ikholomu yesakhiwo sensimbi inendawo encane yesiphambano, engandisa indawo yokusetshenziswa ngempumelelo kwesakhiwo.Ngokuya ngendlela ehlukile yesakhiwo, ingandisa indawo yokusetshenziswa ephumelelayo ngo-4-6%.
Uma kuqhathaniswa nensimbi yokushisela emise okwe-H, ingonga kakhulu abasebenzi nezinto zokwakha, inciphise ukusetshenziswa kwezinto ezingavuthiwe, amandla nokusebenza, ngokucindezeleka okusalayo okuphansi, nokubukeka okuhle kanye nekhwalithi ephezulu.
Ilungele ukwenziwa ngomshini, ukuxhumeka kwesakhiwo nokufaka, futhi kulula ukuyidiliza nokuphinda isetshenziswe.
Ukusetshenziswa kwensimbi ye-H-section kungavikela ngokuphumelelayo imvelo, ebonakala ezicini ezintathu: okokuqala, uma kuqhathaniswa nokhonkolo, ukwakhiwa okomile kungasetshenziswa, okukhiqiza umsindo omncane nothuli oluncane;okwesibili, ngenxa yesisindo esilula, inani lenhlabathi elithathwe ukwakhiwa kwesisekelo lincane.Umonakalo wemithombo yomhlaba mncane.Ngaphezu kwalokho, ukunciphisa okukhulu kwenani lokumba ukhonkolo kanye nezintaba kunenzuzo ekuvikelweni kwendawo ezungezile;okwesithathu, ngemva kokuba impilo yesevisi yesakhiwo sokwakha iphelelwa yisikhathi, inani lemfucuza eqinile elakhiwe ngemva kokudilizwa kwesakhiwo lincane, futhi inani lokuvuselela kabusha izinsiza zensimbi ezilahliwe liphezulu.
Isakhiwo sensimbi ikakhulukazi esenziwe nge-hot-rolled H-beam sinezinga eliphezulu lokukhiqizwa kwezimboni, esilungele ukukhiqizwa kwemishini, ukukhiqizwa okujulile, ukunemba okuphezulu, ukufakwa okulula, nokuqinisekisa ikhwalithi kalula.Ingakhiwa ibe yimboni yangempela yokukhiqiza indlu, imboni yokukhiqiza ibhuloho, imboni yemboni yezimboni, njll.Ukuthuthukiswa kwezakhiwo zensimbi kuye kwadala futhi kwakhuthaza ukuthuthukiswa kwamakhulu ezimboni ezisafufusa.
Ijubane lokwakhiwa kwephrojekthi liyashesha, indawo incane, futhi ifanele ukwakhiwa kwesimo sezulu sonke, futhi ayithinteki kakhulu izimo zezulu.Isivinini sokwakhiwa kwesakhiwo sensimbi esenziwe ngensimbi ye-H-section eshisayo cishe izikhathi ezingu-2-3 zesakhiwo sekhonkrithi, izinga lokubuyisela imali liphindwe kabili, futhi izindleko zezimali ziyancipha, ngaleyo ndlela kulondoloza ukutshalwa kwezimali.Thatha “iJinmao Building” ePudong, Shanghai, “isakhiwo esiphakeme kunazo zonke” ezweni lami njengesibonelo.Isakhiwo esiyinhloko esinomzimba ophakeme ubude obucishe sibe ngamamitha angu-400 saqeda uphahla lwesakhiwo esikhathini esingaphansi kwesigamu sonyaka, kuyilapho ukwakhiwa kwensimbi-ukhonkolo kudinga isikhathi sokwakha seminyaka emibili.

Isicelo:
Izingxenye ze-Beam nekholomu esakhiweni sensimbi sezakhiwo zezimboni nezabantu.
Ukwesekwa kwesakhiwo sensimbi okuthwala umthwalo wezakhiwo zezimboni.
Izinqwaba zensimbi kanye nezakhiwo ezisekela amaphrojekthi angaphansi komhlaba.
Ukwakheka kwemishini yezimboni efana nemboni ye-petrochemical namandla kagesi.
Izingxenye zebhuloho lensimbi ene-span eside.
Isakhiwo sohlaka lokukhiqiza umkhumbi nemishini.
I-Girder isekela izitimela, izimoto, nogandaganda.
Ibhande lembobo yokuthutha, ubakaki onguthelawayeka webhaffle.
