Kungani kufanele sikhethe i-H-beam?
1. Yiziphi izinzuzo nemisebenzi ye-H-beam?
Izinzuzo zeI-H-beam:
Ama-flanges abanzi anikeza ukugoba okuqinile nokuzinza, ukumelana ngokuphumelelayo nemithwalo eqondile; iwebhu esezingeni eliphakeme iqinisekisa ukumelana okuhle kwe-shear. Lo mklamo ufinyelela ukusebenza kahle kokusetshenziswa kwezinto eziphakeme kakhulu, ulula kunezigaba eziqinile kumthamo ofanayo wokuthwala umthwalo, futhi wehlisa isisindo nezindleko zesakhiwo. Okubaluleke nakakhulu, idizayini yayo ye-flange ebanzi yenza ukusebenza mayelana nezimbazo eziqinile nezibuthakathaka kufane, futhi uma isetshenziswa njengekholomu, inozinzo oluhle kakhulu lwe-bidirectional futhi ingamelana ngempumelelo namandla asemaceleni. Ngaphezu kwalokho, indawo ebanzi neyisicaba ye-flange yenza kube lula ukuxhumana kwezinye izingxenye (i-welding noma i-bolting), futhi usayizi ojwayelekile wenza kube lula ukuklama nokwakhiwa. Ukusebenza kwayo okuphelele kanye nokuphumelela kwezindleko kuyenza ibe iphrofayili encanyelwayo yokusebenza kahle okuphezulu kwezingxenye ze-beam nekholomu ezakhiweni zesimanje kanye nezakhiwo zobunjiniyela.
Imisebenzi ye-H-beam:
Izakhiwo zokwakha: Zisebenza njengemishayo namakholomu ezitshalweni zezimboni nezakhiwo eziphakeme, ezivumela izindawo ezinde, ezingenakholamu (njengamafekthri nezakhiwo zokuhlala). Ukuqina kwawo okuphezulu kwezinhlangothi kuwenza afanelekele ukusetshenziswa ezindaweni ezithandwa ukuzamazama komhlaba.
Ingqalasizinda: Asetshenziswa ezinhlelweni ezibanzi noma ezithwala kanzima njengamabhuloho, izisekelo zamachweba, nezithiyo zomgwaqo onguthelawayeka, kanye nezinqwaba zosekelo kumaphrojekthi angaphansi komhlaba.
Izimpahla ezisindayo nezokuthutha: Zisekela amafreyimu ezitimela nemikhumbi, kanye nemishini esindayo, eqinisekisa ukusimama kwesakhiwo.
Ungakhetha kanjani i-H-beam?
1.Nquma amapharamitha we-Cross-Section
Ukuhlonza Imodeli (kusetshenziswa i-GB/T 11263 njengesibonelo):
HW (I-Wide FlangeInsimbi emise okwe-H): Ububanzi be-Flange ≈ ubude besigaba, bufanele amakholomu (ukumelana okuqinile kwe-biaxial buckling).
I-HM (Insimbi Emise okwe-Flange Emaphakathi): Ububanzi be-Flange bumaphakathi, bufaneleka kokubili uhlaka nezinhlelo zokusebenza zekholomu.
I-HN (I-Narrow Flange H-shaped Steel): Ama-flange amancane namawebhu aphezulu, alungele imishayo (ukumelana nokugoba okuhle kakhulu).
Ukucaciswa Isibonelo:
I-HN400×200: Ukuphakama kwesigaba 400mm, ububanzi be-flange 200mm.
Uncamela ukucaciswa okujwayelekile (izindleko ezincishisiwe nokuthenga okulula).
2.Ukukhetha Ibanga Lokubalulekile
Izinto Zensimbi Ezivamile:
I-Q235B: Imithwalo elula, izinhlelo zokusebenza ezingabizi kakhulu.
I-Q355B (ngaphambilini eyayiyi-Q345): Inketho evamile, enamandla aphezulu kanye nokusebenza kahle kwezindleko (kuyanconywa).
I-Q420B: Imithwalo esindayo, izakhiwo ezinde (njengamabhuloho nemishayo yefekthri ye-crane).
Izindawo Ezikhethekile:Insimbi yesimo sezulu (efana ne-Q355NH) iyanconywa ezindaweni ezibolayo. Izingubo ezivimbela umlilo ziyadingeka ezindaweni ezishisa kakhulu.
3.Ukuthuthukisa Umnotho
Iyunithi Yesisindo Sokuthwala Isisindo: Qhathanisa "isisindo imitha kuya kumthamo wokuthwala" isilinganiso samamodeli ahlukene, ubeke phambili ukusebenza kahle okuphezulu kwezigaba.
Ukutholakala Kwemakethe: Gwema ukucaciswa okungathandwayo (okunezikhathi zokuhola ezinde namaprimiyamu amanani aphezulu).
Izindleko Zokuvikela Ukugqwala: Sebenzisa insimbi ye-hot-dip galvanized H-beam ezakhiweni zangaphandle ukuze unciphise ukulungiswa okuqhubekayo.
Umhlinzeki wekhwalithi ephezulu we-H-beam-Royal Group
Royal Groupingumkhiqizi we-H beam. Sinikezela ngezinsizakalo ezahlukahlukene ezihlanganisa ukusika, ukushisela, nosayizi bangokwezifiso. Siphinde sinikeze amanani ancintisanayo emikhiqizweni yethu.Inkampani yethu ikakhulukazi isebenzisana nazo zonke izinhlobo zensimbi, futhi ingomunye wabahlinzeki bensimbi abathathu abahamba phambili eShayina, okuhlanganisa ipuleti lensimbi, ikhoyili yensimbi, ipayipi lensimbi, insimbi engagqwali, imikhiqizo yethusi nemikhiqizo ye-aluminium.
Sinesitokwe esanele semikhiqizo yosayizi abajwayelekile. Ngesikhathi esifanayo, sizohlinzeka ngentengo engcono kakhulu kanye nesivinini sokulethwa esisheshayo. Bheka phambili ekubuzeni kwakho nganoma yisiphi isikhathi.
