I-engeli engagqwali nebha yesiteshi

Ngokuyinhloko ihlukaniswe yaba izinhlobo ezimbili: i-equilateral insimbi engagqwali engela insimbi nokungalingani ohlangothini lwensimbi engagqwali yensimbi. Phakathi kwabo, ohlangothini olungalingani insimbi engagqwali angle steel ingahlukaniswa zibe izinhlobo ezimbili: ububanzi obungalingani futhi ukushuba ezingalingani.
Ukucaciswa kwama-engeli ensimbi engagqwali kuboniswa ubukhulu bobude obuseceleni kanye nobukhulu bezinhlangothi. Kusukela ngo-2010, ukucaciswa kwensimbi yensimbi engenasici yasekhaya yiNo. 2-20, futhi inani lamasentimitha obude obuhlangothini yinombolo. I-engeli yensimbi engagqwali efanayo ivamise ukuba nogqinsi oluseceleni okungu-2-7. Insimbi yensimbi engagqwali engenisiwe ikhombisa ubukhulu bangempela nokuqina kwezinhlangothi ezimbili futhi ikhombisa izindinganiso ezifanele. Ngokuvamile, insimbi enkulu ye-engeli yensimbi engagqwali enobude obuseceleni obungu-12.5 cm noma ngaphezulu iyinsimbi ye-engeli yensimbi engagqwali enosayizi omaphakathi phakathi kuka-12.5 cm no-5 cm, kanye nensimbi encane yensimbi engagqwali enobude obuhlangothini obungu-5 cm noma ngaphansi.
I-oda lokungenisa nokuthekelisa lensimbi yensimbi engagqwali ngokuvamile lisekelwe ekucacisweni okudingekayo ekusetshenzisweni, futhi inombolo yensimbi iyibanga elihambisanayo le-carbon steel grade. Okusho ukuthi, i-engeli yensimbi engagqwali ayinakho ukwakheka okukhethekile nochungechunge lokusebenza ngaphandle kwenombolo ecacisiwe.
Ubude bokulethwa kwensimbi yensimbi engagqwali buhlukaniswe ngezinhlobo ezimbili: ubude obunqunyiwe kanye nomthetho ophindwe kabili. Ibanga lobude obulungisiwe bensimbi yensimbi engagqwali yasekhaya linezigaba ezine ze-3-9m, 4-12m, 4-19m kanye no-6-19m kuye ngenombolo yokucaciswa. Ubude bensimbi yensimbi engenasici yaseJapane yi-6-15m.
Ubude besigaba se-engeli yensimbi engagqwali engalingani bubalwa njengobubanzi bohlangothi olude lwe-engeli yensimbi engagqwali engalingani.
Ukungenisa nokuthekelisa ukuhlelwa kwesimo
Izinsimbi zaseShayina ezingenisiwe nezithunyelwa ngaphandle zine-engeli yensimbi engagqwali inomthamo othile, ikakhulukazi ongeniswe eJapan naseWestern Europe. Izindawo ezithunyelwa ngaphandle ikakhulukazi yiHong Kong, Macao, Southeast Asia, Latin America kanye namazwe ase-Arab. Amabhizinisi okukhiqiza okuthekelisa ngokuyinhloko ayizitshalo zensimbi (izigayo eziginqikayo) eJiangsu, Liaoning, Hebei, Beijing, Shanghai, Tianjin nezinye izifundazwe namadolobha.
Ama-engeli ensimbi engagqwali angenisiwe kakhulukazi amakhulu nezincane zensimbi engagqwali nezinsimbi zomumo okhethekile wama-engeli ensimbi engagqwali. Iningi lezinhlobo ezithunyelwa kwamanye amazwe ama-engeli ensimbi engagqwali aphakathi nendawo afana no-No.6 no-No.7.
Umhleli wezidingo zekhwalithi yokubukeka
Izinga elingaphezulu lensimbi yensimbi engagqwali licaciswe ezingeni. Ngokuvamile, akumele kube namaphutha ayingozi ekusebenziseni, njenge-delamination, crusting, cracks, njll.
Insimbi ye-engeli engalingani
Insimbi ye-engeli engalingani
Ibanga elivumelekile lokuchezuka kwejiyomethri yensimbi ye-engeli yensimbi engagqwali nalo licaciswa ezingeni, ngokuvamile elihlanganisa ukugoba, ububanzi bonqenqema, ukujiya konqenqema, i-engeli ye-apex, isisindo sethiyori, njll., futhi licacisa ukuthi i-engeli yensimbi engagqwali akumele ibe ne-torsion ebalulekile. .

I-304 steel stainless steel channel iyishaneli yensimbi engagqwali eyenziwe ngensimbi engagqwali engu-304. Insimbi yeshaneli yensimbi engagqwali umucu omude wensimbi onomumo we-cross-sectional of groove. Ngokufanayo ne-I-beam, insimbi yensimbi engagqwali nayo ihlukaniswe ngensimbi evamile yesiteshi kanye nensimbi yesiteshi esikhanyayo. Imodeli kanye nokucaciswa kuphinde kuvezwe ngamamilimitha okuphakama okhalweni (h) × ububanzi bomlenze (b) × ukushuba okhalweni (d). Okufana nensimbi yesiteshi esingu-120 × 53 × 5. Ingase futhi ivezwe ngamasentimitha okuphakama okhalweni, njengoba insimbi yesiteshi ibizwa ngensimbi yesiteshi engu-12 #, futhi ububanzi bayo bokucaciswa ngu-5-40 #.
Insimbi yensimbi engagqwali engu-304 iyinsimbi yensimbi engagqwali evame ukusetshenziswa kakhulu, evame ukusetshenziswa ekwakhiweni, ukwakhiwa kohlaka lwensimbi, ukukhiqizwa kwezimoto nezinye izakhiwo zezimboni.
