I-ASTM A36 HEA HEB IPE H Imishayo I Imishayo Yokwakha /H Isakhiwo Sensimbi Esimise nge-(St37-2) (USt37-2) (RSt37-2) A570 Gr.A Ibanga
INQUBO YOKUKHIQISWA KOMKHIQIZO
Inqubo yokukhiqiza yezingaI-H-imishayongokuvamile kuhlanganisa izinyathelo eziyinhloko ezilandelayo:
Ukulungiswa kwempahla eluhlaza: Izinto ezingavuthiwe zokukhiqiza imishayo ye-H ngokuvamile amabhilidi ensimbi. Lawa mabhilidi adinga ukuhlanzwa futhi ashiselwe ukuwalungiselela ukucubungula nokubunjwa okulandelayo.
Ukugoqa okushisayo: Amabhilidi ashisiwe afakwa esigayweni esishisayo ukuze acutshungulwe. Emshinini wokugoqa oshisayo, amabhilidi agingqika ngamasethi amaningi ama-roller, kancane kancane enze isici esiphambanayo esimise okwe-H.
Ukusebenza okubandayo (ongakukhetha): Kwezinye izimo, ukuze kuthuthukiswe ukunemba nekhwalithi engaphezulu yemishayo ye-H, imishayo egoqwe ngokushisayo ingena ezinqubweni zokusebenza ezibandayo, njengokugoqeka okubandayo noma ukudweba.
Ukusika nokuqeda: Ngemva kokugingqika nanoma yikuphi ukusebenza okubandayo, imishayo ye-H iyasikwa futhi iqedwe ngokuvumelana nezidingo zamakhasimende ukuze kuhlangatshezwane nobukhulu obuthile kanye nokucaciswa kobude.
Ukwelashwa okungaphezulu: Imishayo ye-H iyahlanzwa futhi iphathwe ukuze kugwenywe ukugqwala, kuqinisekiswe ikhwalithi enhle yendawo kanye nokungagqwali.
Ukuhlola nokupakishwa: Imishayo ye-H eqediwe ihlolelwa ikhwalithi, okuhlanganisa nokuhlolwa okubonakalayo, ukunemba kobukhulu, kanye nezakhiwo zemishini. Ngemva kokudlula ukuhlolwa, ayapakishwa futhi alungiselelwe ukuthunyelwa ekhasimendeni.

IZICI
Amandla aphezulu: Umumo we-cross-sectional we-H-beams ubanikeza amandla okugoba aphezulu kanye nomthamo wokuthwala umthwalo, okubenza bafaneleke izakhiwo ze-span ezinkulu kanye nezicelo zomthwalo osindayo.
Ukuzinza okuhle: Idizayini ye-cross-sectional ye-H-beams iqinisekisa ukuzinza okuhle kakhulu ngaphansi kokubili kwemithwalo ecindezelayo kanye ne-tensile, okufaka isandla ekuzinzeni okuphelele nokuphepha kwesakhiwo.
Ukwakhiwa okulula: Idizayini ye-H-imishayo yenza kube lula ukuxhumana nokufakwa kalula ngesikhathi sokwakha, ukuthuthukisa inqubekelaphambili yephrojekthi nokusebenza kahle.
Ukusetshenziswa okuphezulu kwezinsiza: Ukwakhiwa kwemishayo ye-H kuvumela ukusetshenziswa kahle kwezakhiwo zensimbi, ukunciphisa udoti wezinto ezibonakalayo nokuba negalelo ekongiweni kwezinsiza kanye nokuvikelwa kwemvelo.
Uhla olubanzi lwezinhlelo zokusebenza: Imishayo ye-H ifanele izakhiwo ezihlukahlukene zokwakha, amabhuloho, nezinhlelo zokusebenza zobunjiniyela bemishini, enikeza amandla okusebenza abanzi.
Kafushane, imishayo ye-H ejwayelekile inamandla aphezulu, ukuzinza okuhle, kanye nokwakhiwa kalula, okuyenza ibe yinsimbi ebalulekile yesakhiwo esetshenziswa kabanzi emikhakheni ehlukahlukene yobunjiniyela.
UKUHLOLWA KOMKHIQIZO
Izidingo zokuhlola ze-H-beam ngokuyinhloko zihlanganisa izici ezilandelayo:
Ikhwalithi yokubukeka: Ukubonakala kwe-H-beam kufanele kuhambisane nezindinganiso ezifanele kanye nokucaciswa kwekhasimende, okubushelelezi futhi okulinganayo, okungenayo izibonda ezisobala, imihuzuko, ukugqwala, noma okunye ukonakala.
Ubukhulu beJiyomethri: Ubude, ububanzi, ubude, ukujiya kwewebhu, nokujiya kwe-flange kwe-H-beam kufanele kuthobelane namazinga afanele kanye nokucaciswa kwekhasimende.
Ukuqondile: Ukuqonda kwe-H-beam kufanele kuthobelane namazinga afanelekile kanye nokucaciswa kwekhasimende, okungaqinisekiswa ngokukala ukuthi iziphetho ezimbili ze-beam ziyahambisana yini noma ngokusebenzisa igeji yokuqondisa.
I-Torsion: Ukunyakaziswa kwe-H-beam kufanele kuthobelane namazinga afanelekile kanye nokucaciswa kwekhasimende, okungaqinisekiswa ngokukala ukuthi izinhlangothi ze-beam zi-perpendicular noma ngokusebenzisa i-torsion gauge.
Ukubekezelela isisindo: Isisindo se-H-beam kufanele sihambisane namazinga afanelekile kanye nokucaciswa kwekhasimende, futhi ukubekezelela isisindo kungaqinisekiswa ngesisindo.
Ukwakheka kwamakhemikhali: Uma i-H-beam izoshiselwa noma icutshungulwe, ukwakheka kwayo kwamakhemikhali kufanele kuthobelane namazinga afanele kanye nokucaciswa kwekhasimende.
Izakhiwo zemishini: Izakhiwo zemishini ze-H-beam kufanele zithobelane namazinga afanelekile kanye nokucaciswa kwekhasimende, okuhlanganisa amandla aqinile, amandla okukhiqiza, ukunwetshwa, njll.
Ukuhlola okungonakali: Uma ukuhlolwa okungonakali kuyadingeka ku-H-beam, kufanele kwenziwe ngokuya ngamazinga afanelekile kanye nokucaciswa kwekhasimende ukuze kuqinisekiswe ikhwalithi yayo yangaphakathi.
Ukupakisha nokumaka: Ukupakishwa nokumakwa kwe-H-beam kufanele kuhambisane nezindinganiso ezifanele kanye nemininingwane yekhasimende ukuze kube lula ukuhamba nokugcinwa.
Kafushane, lapho uhlola ama-H-beam, zonke izimfuneko ezingenhla kufanele zicatshangelwe ngokugcwele ukuze kuqinisekiswe ukuthi ikhwalithi ihlangabezana nezindinganiso ezifanele kanye nokucaciswa kwamakhasimende, ngaleyo ndlela kunikeze abasebenzisi imikhiqizo yekhwalithi ephezulu ye-H-beam.
ISICELO SOMKHIQIZO
Imishayo ye-H evamile yangaphandle isetshenziswa kakhulu ezinkambini zokwakha nezobunjiniyela, kuhlanganisa kodwa kungagcini kulezi zici ezilandelayo:
Ubunjiniyela besakhiwo, ubunjiniyela bebhuloho, ukukhiqizwa kwemishini, ukwakha umkhumbi, ukwakhiwa kwesakhiwo sensimbi,
UKUPAKA KANYE NOKUTHUMELA
Ukupakishwa nokuthuthwa kwemishayo ye-H evamile kuvame ukulandela lezi zinyathelo:
Ukupakisha: Imishayo ye-H ivamise ukupakishwa ngokwezidingo zamakhasimende ukuvikela indawo yayo ekulimaleni. Izindlela zokupakisha ezijwayelekile zifaka ukupakishwa okungenalutho, ukupakishwa kwephalethi yokhuni, nokugoqa ngepulasitiki. Ngesikhathi sokupakishwa, ukunakekelwa kufanele kuthathwe ukuze kuqinisekiswe ukuthi ingaphezulu le-H-imishayo alinawo imihuzuko noma ukugqwala.
Ukulebula: Ulwazi lomkhiqizo, olufana nemodeli, ukucaciswa, kanye nenani, kufanele limakwe ngokucacile ephaketheni ukuze ukhonjwe kalula futhi uphathwe.
Ukulayisha: Ngesikhathi sokulayisha nokuthutha, imishayo ye-H epakishiwe kufanele iphathwe ngokucophelela ukuze kuvinjwe umonakalo kusuka kumthelela noma ukuchotshozwa.
Ezokuthutha: Khetha indlela yezokuthutha efanele, njengamaloli noma ujantshi, bese ukhetha indlela efaneleke kakhulu ngokusekelwe ezidingweni zekhasimende kanye nebanga lokuya endaweni.
Ukukhipha: Lapho ufika endaweni, inqubo yokulayisha kufanele isingathwe ngokucophelela ukugwema ukulimaza imishayo ye-H.
Isitoreji: Gcina imishayo ye-H endaweni yokugcina impahla eyomile, enomoya omuhle ukuze uvimbele ukulimala komswakama noma eminye imiphumela emibi.
