Izinhlobo kanye nemininingwane yensimbi

I. Ipuleti Lensimbi kanye Nesiqeshana
Ipuleti lensimbiIhlukaniswe ngepuleti lensimbi elijiyile, ipuleti lensimbi elincane kanye nensimbi eyisicaba, imininingwane yalo enophawu “a” kanye nobubanzi x ubukhulu x ubude ngamamilimitha. Njenge: ipuleti lensimbi elingu-300x10x3000 elingu-300mm ububanzi, ubukhulu obungu-10mm, ubude bepuleti lensimbi elingu-3000mm.

Ipuleti lensimbi elijiyile: ukujiya kungaphezu kuka-4mm, ububanzi bungu-600~3000mm, ubude bungu-4~12m.
Ipuleti lensimbi elincane: ukujiya okungaphansi kuka-4mm, ububanzi 500~1500mm, ubude 0.5~4m.
Insimbi eyisicaba:ukujiya 4~60mm, ububanzi 12~200mm, ubude 3~9m.
Amapuleti ensimbi kanye nemichilo kuhlukaniswa ngokwendlela yokugoqa:amapuleti aqoqwe abandayofuthiamapuleti asongwe ngokushisa; ngokobukhulu: amapuleti ensimbi amancane (ngaphansi kuka-4mm), amapuleti ensimbi aqinile (4-60mm), amapuleti aqinile kakhulu (ngaphezu kuka-60mm)

2. insimbi egoqwe ngokushisa
2.1I-beam
Insimbi ye-I-beam njengoba igama layo lisho, iyiphrofayili yesigaba esinqunyiwe enomumo ongu-I, ama-flange aphezulu naphansi ayacwebezela.
Insimbi ye-I-beam ihlukaniswe ngobubanzi obujwayelekile, obukhanyayo nobephiko bezinhlobo ezintathu, enophawu "lomsebenzi" kanye nenombolo ye-said. Yiliphi inombolo elimelela ukuphakama kwesigaba senani lamasentimitha. 20 no-32 ngaphezu kwe-I-beam evamile, inombolo efanayo futhi ihlukaniswe ngohlobo lwe-a, b no-a, b, c, ubukhulu bayo bewebhu kanye nobubanzi be-flange ngokulandelana kungama-2mm. Njenge-T36a ukuthi ukuphakama kwesigaba esingu-360 mm, ubukhulu bewebhu besigaba se-I-beam evamile. I-I-beam kufanele izame ukusebenzisa ubukhulu bewebhu obuncane kakhulu bohlobo lwe-a, obubangelwa isisindo sayo esincane, kuyilapho isikhathi sesigaba se-inertia sikhulu kakhulu.
Isikhathi sokungaguquguquki kanye nobubanzi bokujiya kwe-I-beams ohlangothini lobubanzi kuncane kakhulu kunaleyo eqondene nokuphakama. Ngakho-ke, kunemikhawulo ethile ekusetshenzisweni, ngokuvamile efanele amalungu agoba ngendlela eyodwa.
3.insimbi yesiteshi
Insimbi yesiteshi ihlukaniswe izinhlobo ezimbili zensimbi yesiteshi evamile kanye nensimbi yesiteshi elula. Uhlobo lwensimbi yesiteshi olunophawu “[””” kanye nenombolo ye-show. Ngokufanayo ne-I-beam, inani lamasentimitha limelela ukuphakama kwesigaba esiphambeneyo. Njenge-[20 kanye ne-Q [20 ngokulandelana, egameni lokuphakama kwesigaba esingu-200mm sensimbi yesiteshi evamile kanye nensimbi yesiteshi esilula. 14 kanye nensimbi yesiteshi evamile engaphezu kuka-24, inani elifanayo le-sub-a, b kanye no-a, b, c, incazelo efanayo ne-I-beam.

 

4. insimbi ye-engeli
Insimbi ye-engela ihlukaniswe izinhlobo ezimbili zensimbi ye-engela elinganayo kanye nensimbi ye-engela engafani.
I-engeli elinganayo: imilenze yayo emibili eqondile enobude obulinganayo, imodeli yayo enophawu "L" kanye nobubanzi bemilenze x ubukhulu bemilenze ngamamilimitha, njenge-L100x10 yobubanzi bemilenze obungu-100mm, ubukhulu bemilenze obungu-10mm engeli elinganayo.
Ama-engeli angalingani: imilenze yayo emibili eqondile ayilingani, imodeli enophawu "" kanye nobubanzi bezitho ezinde x ububanzi bezitho ezimfushane x ubukhulu bezitho ngamamilimitha, njenge-L100x80x8 yobubanzi bezitho ezinde obungu-100mm, ububanzi bezitho ezimfushane obungu-80mm, ubukhulu bezitho obungu-8mm obungalingani.

 
5. Ukukhanya kwe-H(egoqiwe futhi eshiselwe)
U-H-beam uhlukile ku-I-beam.
(1) i-flange ebanzi, ngakho-ke kube khona i-flange I-beam ebanzi.
(2) Ubuso bangaphakathi be-flange akudingeki bube nomthambeka, ubuso obungaphezulu nobangaphansi buhambisana.
(3) kusukela ohlotsheni lokusatshalaliswa kwezinto, ingxenye ye-I-beam yezinto igxile kakhulu kuwebhu ezungezile, lapho izinhlangothi zesandiso zincane, insimbi encane, kanye ne-H-beam egoqiwe, ukugxila kokusatshalaliswa kwezinto emaphethelweni engxenye.
Ngenxa yalokhu, izici zesigaba esiphambene ne-H-beam ngokusobala ziphakeme kakhulu kunomsebenzi wendabuko, isiteshi, i-angle kanye nokuhlanganiswa kwazo kwesigaba esiphambene, ukusetshenziswa kwemiphumela engcono yezomnotho.
Ngokusho kwesilinganiso samanje sikazwelonke esithi “hot rolled H-beam kanye nesigaba T-beam” (GB/T11263-2005), i-H-beam ihlukaniswe ngezigaba ezine, ezibizwa kanje: i-wide flange H-beam - HW (W for Wide English prefix), imininingwane kusukela ku-100mmx100mm ~ 400mmx400mm; i-middle flange H-beam - HM (M for Middle English prefix), imininingwane kusukela ku-Specification kusukela ku-150mmX100mm ~ 600mmX300mm: I-Narrow Cui-edge H-beam - HN (N for Narrow English prefix); i-thin-walled H-beam - HT (T for Thin English prefix). Kusetshenziswa ukumaka imininingwane ye-H-beam: H kanye nenani lokuphakama kwenani le-h x ububanzi benani le-b x inani lobukhulu be-web t value x inani lobukhulu benani le-flange t2 elishiwoyo. Njenge-H800x300x14x26, okungukuthi, ukuphakama kwesigaba esingu-800mm, ububanzi be-flange obungu-300mm, ukujiya kwewebhu okungu-14mm, ukujiya kwe-flange okungu-26mm H-beam. Noma kuqala kuboniswe ngezimpawu ze-HWHM kanye ne-HN ezithi isigaba se-H-beam, kulandelwe "ukuphakama (mm) x ububanzi (mm)", njenge-HW300x300, okungukuthi, ukuphakama kwesigaba esingu-300mm, ububanzi be-flange obungu-300mm ububanzi be-flange H-beam.
6. Umugqa we-T
I-T-beam yesigaba (Umfanekiso) ihlukaniswe ngezigaba ezintathu, ikhodi ilandelayo: ingxenye yeflange ebanzi ye-T-beam - TW (W yekhanda le-Wide English); engxenyeni yeflange ye-T-beam - TM (M yekhanda le-Middle English); ingxenye yeflange encane ye-T-beam - TN (N yekhanda le-Narrow English). I-T-beam yesigaba nge-H-beam ehambisanayo phakathi kwewebhu ilingana ihlukaniswe ibe. Imininingwane ye-T-beam yesigaba imakwe kanje: T nokuphakama inani le-h x ububanzi inani le-b x ubukhulu bewebhu inani le-t x ubukhulu beflange inani le-t. Njenge-T248x199x9x14, okungukuthi, ukuphakama kwesigaba esingu-248mm, ububanzi bephiko bungu-199mm, ubukhulu bewebhu bungu-9mm, ubukhulu beflange bungu-14mm T-beam. Ingasetshenziswa futhi nge-H-beam efana nokumelwa, njenge-TN225x200 okungukuthi, ukuphakama kwesigaba esingu-225mm, ububanzi be-flange obungu-200mm we-flange encane yesigaba se-T-beam.

7. ipayipi lensimbi yesakhiwo
Ipayipi lensimbi njengengxenye ebalulekile yemikhiqizo yensimbi nensimbi, ngenxa yenqubo yalo yokukhiqiza kanye nesimo sepayipi elisetshenziswa ezinhlotsheni ezahlukene ezimbi futhi lihlukaniswe ngezigaba ezimbili.ipayipi lensimbi elingenamthungo(i-round embi) kanyeipayipi lensimbi elihlanganisiwe(ipuleti, elinobubi) izigaba ezimbili, bheka uMfanekiso.
Isakhiwo sensimbi esivame ukusetshenziswa epayipini lensimbi elingenamthungo eligoqwe ngokushisa kanye nepayipi lensimbi eligoqwe ngokushisa, ipayipi lensimbi eligoqwe futhi eligoqwe kusuka ku-strip yensimbi, ngokuya ngobukhulu bobubanzi bepayipi, futhi lihlukaniswe ngezinhlobo ezimbili zokushisela umthungo oqondile kanye nokushisela okujikelezayo.Ipayipi lensimbi le-LSAWimininingwane yobubanzi bangaphandle obungu-32 ~ 152mm, ubukhulu bodonga obungu-20 ~ 5.5mm. amazinga kazwelonke “epayipi lensimbi le-LSAW” (GB/T13793-2008). Ipayipi lensimbi elingenamthungo lesakhiwo ngokwezinga likazwelonke “ipayipi lensimbi elingenamthungo lesakhiwo” (GB/T8162-2008), kunezinhlobo ezimbili zepayipi eligoqwayo elishisayo nelidonswayo elibandayo, elidonswayo elibandayo likhawulelwe kububanzi bepayipi elincane, ipayipi lensimbi elingenamthungo elidonswayo elishisayo ububanzi bangaphandle obungu-32 ~ 630mm, ubukhulu bodonga obungu-25 ~ 75mm.
Imininingwane yobubanzi obungaphandle x ubukhulu bodonga (mm), njenge-φ102x5. Ipayipi lensimbi elihlanganisiwe ligobile futhi lihlanganiswe ngentambo yensimbi, intengo iphansi kakhulu. Ukusatshalaliswa kwendawo yeso lepayipi lensimbi eliyindilinga kuyafaneleka, isikhathi sokungangeni kuzo zonke izinkomba kanye nobubanzi be-gyration kuyafana futhi kukhulu, ngakho-ke ukusebenza kwamandla, ikakhulukazi lapho ingcindezi ye-axial ingcono, kanye nesimo sayo sejika kwenza kube nokumelana okuncane nomoya, amagagasi, iqhwa, kodwa intengo ibiza kakhulu futhi isakhiwo sokuxhuma sivame ukuba yinkimbinkimbi kakhulu.
