Lub ntsiab lus ntawm kuv - nqaj
Raws li lub npe qhia, Kuv - nqaj yog hom hlau nrog ib qho "Kuv" tus ntoo khaub lig zoo nkauj {1} {1} {1} {1}- seem. Cov chaw sab hauv ntawm cov fligent sab saud thiab qis dua, feem ntau yog 1: 6, ua cov flanges thinner ntawm sab nraud thiab tuab ntawm sab hauv. Qhov no ua rau muaj qhov sib txawv tseem ceeb ntawm tus ntoo khaub lig}} Hla cov yam ntxwv ntawm ob lub dav hlau loj, ua rau siv lub zog tag nrho ntawm cov hlau hauv cov ntawv thov. Txawm hais tias tuab i {{{9} duab ci kuj tau tshwm sim hauv khw, tus qauv ntawm i6 10} Tsov tau txiav txim siab nws cov kev tsis txaus siab hauv torsional.
Cov ntsiab lus ntawm h - Tus Hlau Zoo Li Cas
H {{0} Daim tawv tawv tawv tawv tawv tawv tawv tawv tau muaj npe rau nws tus ntoo khaub lig- seem zoo li tsab ntawv Askiv "h". Nws yog cov siv dav dav hauv cov qauv siv niaj hnub no thiab muaj ntau qhov sib txawv ntawm kuv {{pears. Firstly, nws muaj flanges, thiab qhov thib ob, sab hauv ntawm cov flanges tsis muaj nqes hav tsis muaj txoj kab nqes, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog cov chaw sab saud, nrog rau sab saud thiab qis dua. Tus ntoo khaub lig- Seem siab ntawm h {{{} Daim tawv hlau yog qhov tseem ceeb rau cov tsoos ib txwm zoo dua li cov tsoos kuv zoo siab, raws, thiab cov ces kaum.
H {{0} Daim tawv hlau yog qhov ua tau zoo tshaj plaws nrog kev faib tawm thiab muaj zog tshaj plaws ntawm kev faib tawm thiab muaj zog ntxiv {{{[} qhov hnyav. Cov tog sab hauv ntawm ob sab nraud ntawm h - Daim nyias hlau tsis muaj txoj kab nqes thiab ncaj. Qhov no ua rau lub vuam thiab splicing ntawm h {{{} Daim ci hlau yooj yim dua li tias ntawm cov khoom siv hnyav, uas tuaj yeem txuag tau ntau cov ntaub ntawv thiab lub sijhawm tsim kho. Nws yog ib qho siv tau dav hauv cov ntaub ntawv niaj hnub no.
Cov Ntawv Thov:
Kuv - nqaj
Kev tsim kho nyob (piv txwv li, pem teb joists, vov tsev txhawb).
Cov phiaj xwm kev lag luam uas cov khoom lag luam rau cov nra hnyav.
Automotive thiab Aerospace kev lag luam rau lub teeb ci ntsa iab.
H - nqaj
Hnyav Industrial qauv (piv txwv li, choj, skyscrapers, cranes).
Cov cuab yeej siv tshuab thiab thauj khoom {- belks beeps hauv cov chaw tsim khoom.
Cov haujlwm hauv tsev hluav taws xob zoo li cov tunnels thiab cov nroj tsuag hluav taws xob, qhov twg muaj zog thiab ruaj khov yog qhov tseem ceeb.
Lub zog thiab thauj khoom muaj peev xwm sib piv: h - ci cis vs. Kuv {{ci
Lub zog thiab thau khoom muaj peev xwm ntawm h - Beams thiab kuv}} seem ntawm lawv cov kev ua tau zoo hauv cov ntawv thov txheej txheem. Ob qho zoo hauv kev coj tus nqi khoov, tab sis lawv qhov sib txawv hauv Fleet Geometry thiab Web Configuration tshwm sim hauv kev ua haujlwm sib txawv.
Kuv {- ci, tus cwj pwm los ntawm tapered los yog nkhaus flanges thiab nqaim web, muaj kev txhim khu kev qha bending lub zog rau lub teeb mus rau nruab nrab loads. Lawv cov tshiab profile ua cov khoom siv rau ntsug, ua rau lawv muaj txiaj ntsig hauv kev txhawb nqa ntsug ntsug load zoo li cov roots lossis ru tsev rasts. Txawm li cas los xij, flapted flanges txwv lawv lem tom qab (toj) lo rub tawm cov kab rov tav uas tsis muaj zog, raws li qhov tsis sib xws tsis tuaj yeem tawg tsis tuaj yeem yuam kev pob zeb hauv qab.
H - ci, nrog parallel, uniform - tuab flanges thiab lub vev xaib tuab heev, tshwj xeeb tshaj yog rau hnyav {1} Duty} Duty} Lub luag kuab lom. Lub parallel flanges tsim cov kev faib tawm kev ntxhov siab ntau dua, txhim kho ob qho tib si khoov thiab ntxim nyiam. Qhov tsim no ua rau h {{4 4}} Beams kom wrertal muaj kev ruaj ntseg (piv txwv li cov tshuab hauv qab roob hauv qab) thiab ntau {{Directal rog. Lawv lub vev xaib muaj zog kuj tiv thaiv shear deformation zoo dua li kuv - cov kab teeb thaum raug rau cov khoom hnyav.
Hauv cov ntsiab lus, Kuv - Beams tau raug nqi nrog tsawg dua rau kev muaj peev xwm tsawg dua thiab cov qauv nruj dua rau cov khoom ntim hnyav, nyuaj. Qhov kev xaiv yog nyob ntawm seb daim ntawv thov tau ua ntej cov khoom siv tau ua ntej (Kuv} nqaj thiab muaj zog (h {tshiav).
Lifespan thiab txij nkawm ntawm h - nqaj thiab kuv {{ci
Raug liv thiab cuam tshuam rau yam
H - Beams thiab kuv {leads, feem ntau muaj lub neej, feem ntau muaj lub neej ntawm 30}} 50 xyoo nyob rau hauv ib txwm muaj tshwm sim. Lawv lub durability yog ze ze rau cov khoom ua tau zoo, ib puag ncig cov ntsiab lus thiab kev saib kev txij nkawm. High-qib carbon hlau lossis alloy steel teeb muaj zoo dua corrosion tsis kam, uas tuaj yeem txuas lawv lub neej pabcuam. Txawm li cas los xij, raug rau cov av noo, tshuaj lom neeg lossis huab cua sov siab yuav ua kom lawv poob siab.
Kev Siv Khoom Siv Tseem Ceeb
Kev tu ib txwm yog qhov tseem ceeb. Kev tshuaj xyuas ib txwm yuav tsum tau txais yuav tsis yog- Kev sim tshuaj ntsuam xyuas rau xeb, tawg lossis deformation. Corroded thaj chaw yuav tsum ua sandblasting kev kho thiab anti - corrosion txheej xws li epoxy pleev xim. Zawm Fasteners Xiav thiab txhawb qhov tsis muaj zog tuaj yeem tiv thaiv kev ua tsis tiav. Rau cov nqaj siv hauv cov chaw hnyav, galvanization lossis Cathodic tiv thaiv cov tshuab tuaj yeem muab kev tiv thaiv ntxiv.
Kev ntsuas kev tswj hwm rau lub neej pabcuam txuas ntxiv
Kev tswj kom tsim nyog yog tseem ceeb. Zam kev overloading tuaj yeem tiv thaiv kev puas tsuaj tas mus li ntawm kab teeb. Nrog ceev faj txij nkawm, cov kab no tuaj yeem tshaj lawv lub neej kev pabcuam, kom muaj kev nyab xeeb thiab txo tus nqi hloov chaw.
