Yuav Ua Li Cas Xaiv Qhov H Beam Zoo Rau Kev Lag Luam Tsim Kho?

Hauv kev lag luam kev tsim kho,H beamshu ua "lub hauv paus ntawm cov qauv thauj khoom" - lawv qhov kev xaiv tsim nyog ncaj qha txiav txim siab qhov kev nyab xeeb, kev ruaj khov, thiab kev siv nyiaj tsim nyog ntawm cov haujlwm. Nrog rau kev nthuav dav ntawm kev tsim kho vaj tse thiab kev lag luam tsev siab, yuav ua li cas xaiv H beams uas phim cov kev xav tau ntawm cov haujlwm los ntawm ntau yam khoom tau dhau los ua qhov teeb meem tseem ceeb rau cov engineers thiab cov pab pawg yuav khoom. Hauv qab no yog cov lus qhia ntxaws ntxaws uas tsom mus rau cov yam ntxwv tseem ceeb, cov yam ntxwv tshwj xeeb, thiab cov xwm txheej siv ntawm H beams los pab cov neeg ua lag luam txiav txim siab txog kev tshawb fawb.

Pib Nrog Cov Cwj Pwm Tseem Ceeb: Nkag Siab Txog "Cov Qauv Yooj Yim" ntawm H Beams

Qhov kev xaiv ntawm H beams yuav tsum ua raws li peb yam tseem ceeb uas tsis tuaj yeem sib tham tau, vim tias cov no cuam tshuam ncaj qha rau seb cov khoom puas tuaj yeem ua tau raws li cov qauv tsim qauv.

Qib Khoom SivCov ntaub ntawv feem ntau rau H beams yog carbon structural steel (xws liQ235B, Q355B H Beamhauv cov qauv Suav, lossisA36, A572 H Beamhauv cov qauv Asmeskas) thiab cov hlau tsis tshua muaj zog. Q235B / A36 H Beam yog qhov tsim nyog rau kev tsim kho pej xeem dav dav (piv txwv li, cov tsev nyob, cov chaw tsim khoom me me) vim nws qhov weldability zoo thiab tus nqi qis; Q355B / A572, nrog lub zog siab dua (≥355MPa) thiab lub zog tensile, yog qhov nyiam rau cov haujlwm hnyav xws li choj, cov chaw ua haujlwm loj, thiab cov tsev siab, vim nws tuaj yeem txo qhov loj ntawm lub nqaj thiab txuag qhov chaw.

Cov Lus Qhia Txog Qhov Ntev: H beams yog txhais los ntawm peb qhov tseem ceeb: qhov siab (H), dav (B), thiab lub web thickness (d). Piv txwv li, ib tug H beam uas muaj cim "H300 × 150 × 6 × 8"txhais tau tias nws muaj qhov siab ntawm 300mm, dav ntawm 150mm, lub web tuab ntawm 6mm, thiab flange tuab ntawm 8mm. Cov H beams me me (H≤200mm) feem ntau siv rau cov qauv theem nrab xws li cov joists hauv pem teb thiab cov kev txhawb nqa faib; cov nruab nrab (200mm

Kev Ua Haujlwm Txog TshuabUa tib zoo saib cov ntsuas xws li lub zog tawm los, lub zog tensile, thiab kev cuam tshuam. Rau cov haujlwm hauv thaj chaw txias (piv txwv li, sab qaum teb Suav teb, Canada), H beams yuav tsum dhau qhov kev sim cuam tshuam qis-kub (xws li -40 ℃ kev cuam tshuam toughness ≥34J) kom tsis txhob tawg brittle hauv cov xwm txheej khov; rau thaj chaw seismic, cov khoom lag luam nrog ductility zoo (elongation ≥20%) yuav tsum tau xaiv los txhim kho qhov kev tiv thaiv av qeeg ntawm cov qauv.

Siv Cov Yam Ntxim Saib Tshwj Xeeb: Sib phim "Cov Txiaj Ntsig Khoom" rau Cov Kev Xav Tau ntawm Qhov Project

Piv nrog cov seem hlau ib txwm zoo liI-beamsthiab cov hlau channel, H beams muaj cov yam ntxwv sib txawv uas ua rau lawv haum rau cov xwm txheej kev tsim kho tshwj xeeb - kev nkag siab txog cov txiaj ntsig no yog qhov tseem ceeb rau kev xaiv lub hom phiaj.

Kev Ua Haujlwm Zoo Tshaj PlawsCov H-zoo li tus ntoo khaub lig-seem ntawm H beams faib cov khoom siv tau zoo dua: cov flanges tuab (qhov sab saud thiab qis kab rov tav) dais feem ntau ntawm lub sijhawm khoov, thaum lub vev nyias (qhov nruab nrab ntsug) tiv taus lub zog shear. Qhov kev tsim no tso cai rau H beams kom ua tiav lub peev xwm thauj khoom siab dua nrog kev siv hlau tsawg dua - piv rau I-beams ntawm tib qhov hnyav, H beams muaj lub zog khoov siab dua 15% -20%. Tus cwj pwm no ua rau lawv zoo tagnrho rau cov haujlwm nrhiav kev txuag nqi thiab cov qauv sib dua, xws li cov tsev prefabricated thiab kev tsim kho modular.

Muaj zog ruaj khov & Yooj yim rau kev teeb tsaQhov sib npaug ntawm H seem ua rau txo qhov kev hloov pauv torsional thaum lub sijhawm tsim kho, ua rau H beams ruaj khov dua thaum siv ua cov nqaj hlau loj. Tsis tas li ntawd, lawv cov flanges tiaj tiaj yooj yim txuas nrog lwm cov khoom (piv txwv li, bolts, welds) yam tsis muaj kev ua tiav nyuaj - qhov no txo ​​​​​​lub sijhawm tsim kho ntawm qhov chaw los ntawm 30% piv rau cov seem hlau tsis sib xws, uas yog qhov tseem ceeb rau cov haujlwm ceev ceev xws li cov chaw lag luam thiab cov chaw tsim kho thaum muaj xwm txheej ceev.

Zoo corrosion & hluav taws tsis kam (nrog kev kho mob)Cov H beams uas tsis tau ua tiav lawm yuav yooj yim xeb, tab sis tom qab kev kho saum npoo xws li kub-dip galvanizing lossis epoxy txheej, lawv tuaj yeem tiv taus xeb hauv cov av noo lossis ntug dej hiav txwv (piv txwv li, cov platforms offshore, txoj kev ntug dej hiav txwv). Rau cov xwm txheej kub siab xws li cov chaw ua haujlwm hauv kev lag luam nrog cov cub tawg, cov H beams uas tiv taus hluav taws (coated nrog intumescent fire-retardant xim) tuaj yeem tswj tau lub peev xwm thauj khoom ntau dua 120 feeb yog tias muaj hluav taws, ua tau raws li cov qauv kev nyab xeeb hluav taws nruj.

Cov Xwm Txheej Siv Rau Lub Hom Phiaj: Kev Xaiv Yog

Cov haujlwm tsim kho sib txawv muaj cov kev cai sib txawv rau H-beams. Tsuas yog los ntawm kev sib phim cov khoom siv nrog cov kev cai ntawm qhov chaw thiaj li ua rau lawv tus nqi siab tshaj plaws. Hauv qab no yog peb qhov xwm txheej siv thiab kev sib xyaw ua ke uas pom zoo.

Cov Tsev Nyob thiab Cov Tsev Lag Luam SiabRau cov tsev uas muaj 10-30 plag tsev, cov H-beams nruab nrab uas ua los ntawm Q355B hlau (H250 × 125 × 6 × 9 txog H350 × 175 × 7 × 11) raug pom zoo. Lawv lub zog siab txhawb nqa qhov hnyav ntawm ntau lub plag tsev, thaum lawv qhov me me txuag chaw rau kev tsim sab hauv.

Cov Choj thiab Cov Qauv NtevCov choj ntev (ntev ≥50 meters) lossis cov ru tsev chaw ua si yuav tsum tau cov H-beams loj, muaj zog (H400 × 200 × 8 × 13 lossis loj dua).

Cov Hoobkas Lag Luam thiab Cov Tsev Khaws KhoomCov chaw ua haujlwm hnyav (xws li cov chaw tsim tsheb) thiab cov tsev rau khoom loj xav tau H-beams uas muaj peev xwm txhawb nqa qhov hnyav ntawm cov khoom siv lossis kev teeb tsa cov khoom thauj.
