Yibuphi ubuchwepheshe bokucubungula insimbi ye-H-beam?

Uma kukhulunywa ngobuchwepheshe bokucubungula insimbi yesigaba se-H, kunezindlela eziningana ezivame ukusetshenziswa ukukhiqiza umsebe wensimbi wesakhiwo wekhwalithi ephezulu. Lawa masu abalulekile ekuqinisekiseni ukuthi umsebe wensimbi yekhabhoni we-h uhlangabezana nezindinganiso ezidingekayo zokwakha kanye nezicelo zezimboni.
Enye yezindlela eziyinhloko zobuchwepheshe bokucubungula izinsimbi ze-H-beams zensimbi ezishisayo ukugoqa okushisayo. Izingxenye ze-H zensimbi ezigoqwayo ezishisayo zikhiqizwa ngokushisa i-billet yensimbi ize ifike esimweni se-ductile bese iyidlulisa ochungechungeni lwezingqimba ukuze yakhe isimo se-H esifiselekayo. Le nqubo ingakhiqizaInsimbi yogongolo lwe-H engu-150*150mmngezilinganiso eziqondile kanye nobuqotho obuhle kakhulu besakhiwo.
Ngaphezu kokugoqa okushisayo, ukugaya ngogesi kungenye indlela ebalulekile yokucubungula ugongolo lwensimbi olunomumo we-H. Amakholomu ensimbi agqitshwe ngogesi we-H ambozwe ngesendlalelo se-zinc ukuvikela insimbi ekugqwaleni, okwenza ibe yindawo ekahle yokusetshenziswa kwangaphandle kanye nezimboni lapho ukuchayeka ezintweni kuyindaba yokucatshangelwa. Le nqubo yandisa ukuqina kanye nokuphila kwenkonzo yezinsimbi ze-H, okuqinisekisa ukuthi zingakwazi ukumelana nezimo zemvelo ezinzima.
Ngaphezu kwalokho, ukusetshenziswa kwezingxenye ze-H zensimbi ezigoqekile ezishisayo zekhwalithi ephezulu, ikakhulukaziInsimbi ye-H-beam ye-Q235Bkufakazela ubuchwepheshe bokucubungula obusezingeni eliphezulu obusetshenziswa ekukhiqizweni kwabo. Lezi zinsika zensimbi ezimise okwe-H zakhiwa kusetshenziswa ubuchwepheshe obuthuthukisiwe kanye nezinyathelo eziqinile zokulawula ikhwalithi ukuqinisekisa ukuthi zihlangabezana nezindinganiso eziphakeme kakhulu zemboni.
Abakhiqizi bezinsimbi ze-H bensimbi baseShayina baziwa ngobuchwepheshe babo ekucubunguleni izakhiwo ze-H-beam besebenzisa ubuchwepheshe besimanje. Ukuzibophezela kwabo ekubunjweni kokunemba kanye nokuqinisekiswa kwekhwalithi kubenze baba umthombo othembekile wemikhiqizo eyahlukahlukene ye-H-beam ukuze kuhlangatshezwane nezidingo ezahlukene zokwakha nezezimboni.

Ngamafuphi, ubuchwepheshe bokucubungula insimbi yesigaba (ikakhulukazi insimbi yesigaba se-H) budlala indima ebalulekile ekuhlinzekeni ikhwalithi nokusebenza okuhle kakhulu. Kungakhathaliseki ukuthi yi-hot rolled steel H-beams,izinsika zensimbi ye-H ezihlanganisiwe, noma i-prime hot rolled steel H beam, ukusetshenziswa kwezindlela zokucubungula ezithuthukisiwe kuqinisekisa ukuthi lezi zingxenye zensimbi ezakhiwe zihlangabezana nezindinganiso eziphakeme kakhulu zokuqina, amandla kanye nokuthembeka.
