Yibuphi ubuchwepheshe bokucutshungulwa kwensimbi ye-H-beam?

Uma kukhulunywa ngobuchwepheshe bokucubungula insimbi yesigaba H, kunezindlela ezimbalwa ezivame ukusetshenziswa zokwenza insimbi yesakhiwo sekhwalithi ephezulu H.Lawa masu abalulekile ekuqinisekiseni ukuthi i-carbon steel h beam ihlangabezana nezicaciso namazinga adingekayo ekwakheni nasezimbonini zokusebenza.
Obunye bobuchwepheshe obuyinhloko bokucutshungulwa kwensimbi ye-hot roll H-imishayo ukugoqa okushisayo.Izingxenye ze-H zensimbi egoqwe ngokushisayo zikhiqizwa ngokushisisa i-billet yensimbi ize ifike endaweni eyi-ductile bese iyidlulisa ochungechungeni lwemiqulu ukuze yenze umumo we-H oyifunayo.Le nqubo ingakhiqiza150 * 150mm H insimbi yensimbiezinobukhulu obunembe kanye nobuqotho besakhiwo esihle kakhulu.
Ngaphezu kokuginqika okushisayo, ukwenza i-galvanizing kungobunye ubuchwepheshe bokucubungula obubalulekile be-H shape steel beam.Amakholomu ensimbi enama-H-beam ambozwe ngesendlalelo se-zinc ukuze avikele insimbi ekugqwaleni, okuwenza alungele ukusetshenziswa kwangaphandle nasezimbonini lapho ukuchayeka kuzinto kuwukucatshangelwa.Le nqubo ikhulisa ukuqina nempilo yesevisi yensimbi ye-H-imishayo, iqinisekisa ukuthi ingakwazi ukumelana nezimo zemvelo ezinzima.
Ngaphezu kwalokho, ukusetshenziswa okusezingeni eliphezulu hot-roll roll steel H-izigaba, ikakhulukaziQ235B insimbi H-ugongoloifakazela ubuchwepheshe bokucubungula obusezingeni eliphezulu obusetshenziswa ekukhiqizeni kwabo.Le mishayo yensimbi emise okwe-H ikhiqizwa kusetshenziswa ubuchwepheshe obuthuthukisiwe kanye nezinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ukuthi ihlangabezana namazinga aphezulu embonini.
Abakhiqizi bensimbi yase-China H baziwa ngobungcweti babo ekucubunguleni izakhiwo ze-H-beam besebenzisa ubuchwepheshe besimanje.Ukuzibophezela kwabo kubunjiniyela obunembayo nokuqinisekiswa kwekhwalithi kubenze umthombo othembekile wemikhiqizo ehlukahlukene ye-H-beam ukuhlangabezana nezidingo ezahlukene zokwakha nezezimboni.

Ngamafuphi, ubuchwepheshe bokucubungula kwensimbi yesigaba (ikakhulukazi insimbi ye-H-section) idlala indima ebalulekile ekunikezeni ikhwalithi nokusebenza okuhle kakhulu.Noma ngabe insimbi egoqiwe eshisayo i-H,izigxobo zensimbi engu-galvanized H, noma i-prime hot roll rolled steel H, ukusetshenziswa kwezindlela ezithuthukisiwe zokucubungula kuqinisekisa ukuthi lezi zingxenye zensimbi zesakhiwo zihlangabezana nezindinganiso eziphakeme kakhulu zokuqina, amandla nokuthembeka.
