I-HI Beam yensimbi engagqwali
Incazelo emfushane:
I-“H Beam” ibhekisela ezingxenyeni zesakhiwo ezibunjwe njengohlamvu “H” ezivame ukusetshenziswa ekwakheni nasezindleleni ezahlukene zesakhiwo.
Insimbi Engagqwali H Beam:
I-H Beam yensimbi engagqwali yizingxenye zesakhiwo ezibonakala nge-cross-section yazo enomumo we-H. Lezi ziteshi zenziwe ngensimbi engagqwali, i-alloy engagqwali eyaziwa ngokuqina kwayo, ukuhlanzeka, kanye nokukhanga kobuhle. Iziteshi ze-H zensimbi engagqwali zithola ukusetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa ukwakhiwa, ukwakhiwa kwezakhiwo, kanye nokukhiqiza, lapho ukumelana kwazo nokugqwala kanye namandla kuzenza zibe ukukhetha okuthandwayo kokusekelwa kwesakhiwo kanye nokuklama. Lezi zingxenye zivame ukusetshenziswa ekwakhiweni kwezinhlaka, izisekelo, kanye nezinye izakhi zesakhiwo lapho kokubili amandla nokubukeka okucwebezelayo kubalulekile.

Iwebhu:
Iwebhu isebenza njengengqikithi ephakathi yomshayo, ngokuvamile ihlukaniswa ngokusekelwe ekujiyeni kwayo. Isebenza njengesixhumanisi sesakhiwo, idlala indima ebalulekile ekulondolozeni ubuqotho bomshayo ngokuxhuma nokuhlanganisa ama-flange amabili, isabalalise futhi ilawule ngempumelelo ingcindezi.
I-Flange:
Izingxenye zensimbi ezingenhla neziphansi ezisicaba zithwala umthwalo oyinhloko. Ukuqinisekisa ukusatshalaliswa kwengcindezi okufanayo, sibamba ama-flange. Lezi zingxenye ezimbili zisebenza ngokufanayo, futhi ngokomongo we-I-beams, zinezandiso ezifana namaphiko.

Yiziphi izindlela zokushisela?
Izindlela zokushisela zifaka phakathi ukushisela kwe-arc, ukushisela okuvikelwe ngegesi (i-MIG/MAG welding), ukushisela kokumelana, ukushisela nge-laser, ukushisela kwe-arc ye-plasma, ukushisela kwe-friction stir, ukushisela kwengcindezi, ukushisela kwe-electron beam, njll. Indlela ngayinye inezinhlelo zokusebenza nezici ezihlukile, ezifanele izinhlobo ezahlukene zezinto zokusebenza kanye nezidingo zokukhiqiza. I-arc isetshenziselwa ukukhiqiza amazinga okushisa aphezulu, incibilikise insimbi ebusweni bento yokusebenza ukuze yakhe uxhumano. Izindlela ezivamile zokushisela kwe-arc zifaka phakathi ukushisela kwe-arc ngesandla, ukushisela kwe-argon arc, ukushisela kwe-arc engaphansi komhlaba, njll. Ukushisa okukhiqizwa ukumelana kusetshenziselwa ukuncibilikisa insimbi ebusweni bento yokusebenza ukuze kwakhe uxhumano. Ukushisela kokumelana kuhlanganisa ukushisela okuqondile, ukushisela komthungo kanye nokushisela kwe-bolt.
Noma nini lapho kungenzeka, ukushisela kufanele kwenziwe esitolo lapho ikhwalithi yokushisela ivame ukuba ngcono khona, ukushisela esitolo akudingi isimo sezulu futhi ukufinyelela ekuxhumaneni kuvulekile impela. Ukushisela kungahlukaniswa njengokuyisicaba, okuvundlile, okuqondile, kanye nokuphezulu. Kungabonakala ukuthi ukushisela okuyisicaba kulula kakhulu ukukwenza; kuyindlela ekhethwayo. Ukushisela okungaphezulu, okuvame ukwenziwa ensimini, kufanele futhi kugwenywe lapho kungenzeka khona ngoba kunzima futhi kuthatha isikhathi esiningi, futhi ngenxa yalokho kubiza kakhulu.
Ama-groove welds angangena esitho esixhunyiwe engxenyeni yobukhulu belungu, noma angangena ebunzimeni obugcwele belungu elixhunyiwe. Lawa abizwa ngokuthi i-partialjoint penetration (PJP) kanye ne-complete-joint penetration (CJP), ngokulandelana. Ama-complete-penetration welds (abizwa nangokuthi i-full-penetration noma i-“full-pen” welds) ahlanganisa ukujula konke kwemikhawulo yamalungu axhunyiwe Ama-partial penetration welds asebenza kahle kakhulu futhi asetshenziswa lapho imithwalo esetshenzisiwe ingadingeki i-full-penetration weld. Angasetshenziswa futhi lapho ukufinyelela emseleni kukhawulelwe kolunye uhlangothi lokuxhumana.

Yiziphi izinzuzo zokushisela i-arc engaphansi komhlaba?
Ukushisela i-arc ecmerged kufaneleka ezindaweni ezizenzakalelayo nezinomthamo ophezulu. Kungaqeda umsebenzi omkhulu wokushisela ngesikhathi esifushane futhi kuthuthukise ukusebenza kahle kokukhiqiza. Ukushisela i-arc ecmerged kufaneleka ezindaweni ezizenzakalelayo nezinomthamo ophezulu. Kungaqeda umsebenzi omkhulu wokushisela ngesikhathi esifushane futhi kuthuthukise ukusebenza kahle kokukhiqiza. Ukushisela i-arc ecmerged kuvame ukusetshenziselwa ukushisela amashidi ensimbi ajiyile ngoba amandla ayo aphezulu kanye nokungena okuphezulu kwenza kube ngcono kulezi zinhlelo zokusebenza. Njengoba ukushisela kumbozwe yi-flux, i-oxygen ingavinjelwa ngempumelelo ukuthi ingene endaweni yokushisela, ngaleyo ndlela kuncishiswe amathuba okushisela kanye nokuchitheka. Uma kuqhathaniswa nezinye izindlela zokushisela ezenziwe ngesandla, ukushisela i-arc ecmerged kuvame ukwenziwa kube lula kakhulu, kunciphisa izidingo eziphezulu zamakhono abasebenzi. Ekushiseni i-arc ecmerged, izintambo eziningi zokushisela kanye nama-arcs zingasetshenziswa ngesikhathi esisodwa ukuze kufezwe ukushisela kweziteshi eziningi (ezinezingqimba eziningi) nokuthuthukisa ukusebenza kahle.
Yiziphi izinhlelo zokusebenza ze-Stainless Steel H beams?
Izinsimbi ze-H zensimbi engagqwali zisetshenziswa kabanzi ekwakheni, ubunjiniyela basolwandle, imishini yezimboni, izimoto, amaphrojekthi wamandla, kanye neminye imikhakha ngenxa yokumelana nokugqwala nokuqina kwazo. Zinikeza ukwesekwa kwesakhiwo kumaphrojekthi okwakha futhi zidlala indima ebalulekile ezindaweni ezidinga ukumelana nokugqwala, njengezindawo zasolwandle noma zezimboni. Ngaphezu kwalokho, ukubukeka kwazo kwesimanje nobuhle kuzenza zifanelekele ukusetshenziswa kwezakhiwo kanye nokuklama kwangaphakathi.
Iqonde kangakanani i-Stainless Steel HI beam?
Ukuqondile kwe-H-beam yensimbi engagqwali, njenganoma iyiphi ingxenye yesakhiwo, kuyisici esibalulekile ekusebenzeni nasekufakweni kwayo. Ngokuvamile, abakhiqizi bakhiqiza i-H-beam yensimbi engagqwali enezinga elithile lokuqondile ukuze ihlangabezane nezindinganiso kanye nemininingwane yemboni.
Indinganiso eyamukelekayo yemboni yokuqondakala kwensimbi yesakhiwo, kufaka phakathi izinsimbi ze-H zensimbi engagqwali, ivame ukuchazwa ngokwemibandela yokuphambuka okuvunyelwe kusuka emgqeni oqondile ngaphezu kobude obubekiwe. Lokhu kuphambuka kuvame ukuvezwa ngokwemigomo yamamilimitha noma amasentimitha okushelela noma ukufuduka okuseceleni.
Isingeniso ngesimo somsebe we-H?
Ukuma kwensimbi ye-I-beam okunezingqimba, okwaziwa kakhulu ngokuthi "工字钢" (gōngzìgāng) ngesiShayina, kufana nohlamvu "H" uma luvulwa. Ngokukhethekile, ingxenye ehambisanayo ngokuvamile inezingqimba ezimbili ezivundlile (ama-flange) phezulu naphansi kanye nebha ephakathi eqondile (iwebhu). Lo mumo we-"H" unikeza amandla aphezulu kanye nokuqina kwensimbi ye-I-beam, okwenza kube yinto evamile yokwakha ekwakheni nasebunjiniyelani. Umumo oklanyelwe wensimbi ye-I-beam uyivumela ukuthi ifanelekele izinhlelo zokusebenza ezahlukahlukene zokuthwala umthwalo kanye nokusekela, njengemishayo, amakholomu, kanye nezakhiwo zamabhuloho. Lokhu kulungiselelwa kwesakhiwo kwenza insimbi ye-I-beam isabalalise imithwalo ngempumelelo lapho ibhekene namandla, inikeze ukwesekwa okuqinile. Ngenxa yesimo sayo esiyingqayizivele kanye nezici zesakhiwo, insimbi ye-I-beam isetshenziswa kabanzi emikhakheni yokwakha kanye nobunjiniyela.
