Izinhlobonhlobo kanye nokucaciswa kwensimbi

I. I-Steel Plate kanye ne-Strip
Ipuleti lensimbiihlukaniswe yaba ipuleti lensimbi eliwugqinsi, ipuleti lensimbi elincanyana nensimbi eyisicaba, imininingwane yalo enophawu oluthi “a” kanye nobubanzi buka-x ukushuba x ubude ngamamilimitha. Okufana: a 300x10x3000 ukuthi ububanzi 300mm, ukujiya 10mm, ubude 3000mm steel plate.

Ipuleti lensimbi eliwugqinsi: ukujiya okukhulu kuno-4mm, ububanzi 600 ~ 3000mm, ubude 4 ~ 12m.
Ipuleti lensimbi elincanyana: ukujiya okungaphansi kuka-4mm, ububanzi 500 ~ 1500mm, ubude 0.5 ~ 4m.
Insimbi eyisicabaUbukhulu 4 ~ 60mm, ububanzi 12 ~ 200mm, ubude 3 ~ 9m.
Amapuleti ensimbi nemichilo ahlukaniswa ngokwendlela yokugoqa:amapuleti rolling abandayofuthiamapuleti asongwe ashisayo; ngokobukhulu: amapuleti ensimbi amancane (ngaphansi kuka-4mm), amapuleti ensimbi awugqinsi (4-60mm), amapuleti awugqinsi engeziwe (ngaphezu kuka-60mm)

2. insimbi egoqwe ngokushisayo
2.1I-beam
Insimbi ye-I-beam njengoba igama layo liphakamisa, iyiphrofayili yesigaba esiphambanayo esimise okwe-I, ama-flange aphezulu naphansi ayashawa.
Insimbi ye-I-beam ihlukaniswe yaba ejwayelekile, ububanzi obukhanyayo nobubanzi bephiko lezinhlobo ezintathu, ngophawu "umsebenzi" kanye nenombolo ethi. Iyiphi inombolo emele ubude besigaba senani lamasentimitha. 20 kanye no-32 ngaphezu kwe-I-beam evamile, inombolo efanayo futhi ihlukaniswe yaba uhlobo, b no-a, b, c, ukushuba kwayo kwewebhu kanye nobubanzi be-flange ngokulandelanayo ku-2mm. njenge-T36a ubude besigaba esiphambanayo esingu-360 mm, ukujiya kwewebhu kwekilasi le-I-beam evamile. I-I-beams kufanele izame ukusebenzisa ukujiya kwewebhu okuncanyana kakhulu kohlobo a, okungenxa yesisindo sayo esilula, kuyilapho umzuzu wesigaba esiphambanayo we-inertia mkhulu ngokuqhathaniswa.
Isikhathi se-inertia kanye ne-radius ye-gyration yama-I-imishayo ohlangothini lobubanzi mancane kakhulu kunalawo asendleleni yokuphakama. Ngakho-ke, kunemikhawulo ethile esicelweni, ngokuvamile efanele amalungu aguqa indlela eyodwa.
3.insimbi yesiteshi
Insimbi yesiteshi ihlukaniswe yaba izinhlobo ezimbili zensimbi evamile yesiteshi nensimbi engasindi yesiteshi. Uhlobo lwensimbi lwesiteshi olunophawu """ kanye nenombolo ethi. Okufanayo ne-I-beam, inombolo yamasentimitha iphinda imele ukuphakama kwesigaba esiphambanayo. Njenge-[20 kanye no-Q [20 ngokulandelanayo, egameni lesigaba sobude obungu-200mm wensimbi evamile yensimbi nensimbi yokukhanya. I-14 nangaphezulu kuka-24 ishaneli evamile incazelo, uhlobo olufanayo lwe-b, inombolo efanayo ye-b kanye ne-sub - inombolo efanayo I-beam.

 

4. insimbi ye-angle
I-Angle steel ihlukaniswe yaba izinhlobo ezimbili zensimbi ye-equilateral angle kanye nensimbi engalingani.
I-engeli elinganayo: imilenze yayo ehambisanayo emibili enobude obulinganayo, imodeli yayo enophawu “L” nobubanzi bemilenze x ukujiya kwemilenze ngamamilimitha, njenge-L100x10 ngobubanzi bezitho obungu-100mm, ukujiya kwemilenze engu-10mm e-engeli elinganayo.
Ama-engeli angalingani: izitho zayo ezimbili ezihambisanayo azilingani, imodeli enophawu “” nobubanzi bemilenze emide x ububanzi bemilenze emifushane x ububanzi bomlenze ngamamilimitha, njenge-L100x80x8 ngobubanzi bomlenze obude obungu-100mm, ububanzi bemilenze emifushane bungu-80mm, ukujiya kwemilenze engu-8mm engalingani.

 
5. I-H-beam(yagingqika yashiselwa)
I-H-beam ihlukile ku-I-beam.
(1) i-flange ebanzi, ngakho-ke kuye kwaba ne-flange ebanzi ethi I-beam.
(2) Indawo yangaphakathi ye-flange ayidingi ukuba nomthambeko, izindawo ezingaphezulu nezingaphansi zihambisana.
(3) kusukela ohlotsheni lokusatshalaliswa kwezinto ezibonakalayo, i-I-beam cross-section yento esetshenziswayo igxile kakhulu kuwebhu nxazonke, kuya ezinhlangothini zesandiso, insimbi encane, kanye ne-H-beam egoqwe, ukugxila kokusatshalaliswa kwempahla emaphethelweni engxenye.
Ngenxa yalokhu, izici ze-H-beam cross-section ngokusobala ziphakeme kunomsebenzi wendabuko, isiteshi, i-engeli kanye nenhlanganisela yazo ye-cross-section, ukusetshenziswa kwemiphumela engcono yezomnotho.
Ngokwendinganiso kazwelonke yamanje “i-hot rolled H-beam nesigaba T-beam” (GB/T11263-2005), i-H-beam ihlukaniswe yaba izigaba ezine, eziqokwe kanje: i-wide flange H-beam - HW (W for Wide English prefix), imininingwane evela ku-100mmx100mm ~ 400mmx40; i-flange emaphakathi i-H-beam - HM (M yesiqalo sesiNgisi Esimaphakathi), imininingwane esuka ku-Specification from 150mmX100mm~600mmX300mm: Narrow Cui-edge H-beam - HN (N for Narrow English prefix); i-H-beam enezindonga ezincane - HT (T ye-Thin English prefix). Kusetshenziswa umaka wokucaciswa kwe-H-beam: H kanye nenani lobude bevelu engu-h x ububanzi bevelu engu-b x inani logqinsi lwenani elingu-t lewebhu x inani logqinsi lwevelu ye-flange engu-t2 eshiwo. Okufana ne-H800x300x14x26, okungukuthi, ubude besigaba esingu-800mm, ububanzi be-flange bungu-300mm, ukushuba kwewebhu okungu-14mm, ukujiya kwe-flange okungu-26mm H-beam. Noma kuvezwe kuqala ngezimpawu ze-HWHM ne-HN zathi isigaba se-H-beam, kulandelwa "ubude (mm) x ububanzi (mm)", njenge-HW300x300, okungukuthi, ubude besigaba esingu-300mm, ububanzi be-flange obungu-300mm ububanzi be-flange H-beam.
6. I-T-beam
I-Sectional T-beam (Figure) ihlukaniswe izigaba ezintathu, ikhodi ilandelayo: ingxenye ebanzi ye-flange ye-T-beam - TW (W ye-Wide English head); engxenyeni ye-flange ye-T-beam - TM (M yekhanda lesiNgisi esiPhakathi); ingxenye ye-flange ewumngcingo ye-T-beam - TN (N yekhanda le-Narrow English). I-Sectional T-beam nge-H-beam ehambisanayo phakathi nendawo yewebhu ihlukaniswe yaba. Izicaciso ze-T-beam ezimakwe ngokuthi: T nobude h inani x ububanzi b inani x ukujiya kwewebhu t inani x ukujiya kwe-flange t inani. Okufana ne-T248x199x9x14, okungukuthi, ngobude besigaba esingu-248mm, ububanzi bephiko bungu-199mm, ukujiya kwewebhu okungu-9mm, ukujiya kwe-flange okungu-14mm T-beam. Ingasetshenziswa futhi nokumelela okufanayo kwe-H-beam, okufana ne-TN225x200 okungukuthi, ubude besigaba obungu-225mm, ububanzi be-flange obungu-200mm wesigaba esincane se-T-beam.

7.ipayipi lensimbi yesakhiwo
Ipayipi lensimbi njengengxenye ebalulekile yemikhiqizo yensimbi neyensimbi, ngenxa yenqubo yayo yokukhiqiza kanye nokuma kwepayipi elisetshenziswa kabi elihlukile futhi lihlukaniswe labaipayipi lensimbi engenamthungo(round embi) kanyeipayipi lensimbi elishiselwe(ipuleti, elinobubi) izigaba ezimbili, bheka uMdwebo.
Isakhiwo sensimbi esivame ukusetshenziswa epayipini lensimbi eligoqelwe elingenamthungo elishisayo kanye nepayipi lensimbi elishiselwe, ipayipi lensimbi elihlanganisiwe eligoqiwe futhi elishiselwe kusuka emgqeni wensimbi, ngokusho kobukhulu bobubanzi bepayipi, futhi ihlukaniswe yaba izinhlobo ezimbili zokushisela umphetho oqondile kanye nokushisela okuvunguzayo.Ipayipi yensimbi ye-LSAWimininingwane yobubanzi obungaphandle obungama-32 ~ 152mm, ukujiya kodonga okungama-20 ~ 5.5mm. amazinga kazwelonke "LSAW steel pipe" (GB/T13793-2008). Ipayipi lensimbi elingenamthungo ngokwezinga likazwelonke "ipayipi lensimbi elingenamthungo" (GB/T8162-2008), kunezinhlobo ezimbili zamapayipi ashisayo, adonswe ngokubanda, adonswa ngokubanda anomkhawulo wamapayipi amancane, ipayipi elishisayo eligoqelwe elingenamthungo ububanzi obungaphandle obungu-32 ~ 630mm, ukujiya kodonga okungu-25mm.
Imininingwane engaphandle kobubanzi x ukujiya kodonga (mm), njengokuthi φ102x5. Ipayipi lensimbi elishiselwe ligobile futhi lishiselwe umugqa wensimbi, intengo iphansi. Ipayipi lensimbi cross-section symmetry iso endaweni ukusatshalaliswa kunengqondo, umzuzu inertia kuzo zonke izinkomba kanye engaba of gyration iyafana futhi emikhulu, ngakho ukusebenza kwamandla, ikakhulukazi lapho ingcindezi axial kungcono, futhi ijika ijamo layo kwenza kube kuncane ukumelana nomoya, amagagasi, iqhwa, kodwa intengo ibiza kakhulu futhi isakhiwo sokuxhuma ngokuvamile siyinkimbinkimbi.
