1.What yog cov ntawv teev cov ntaub ntawv tshwj xeeb ntawm Q345b hauv high-}}} maj txhim kho cov qauv?
Beams thiab kab ntawv: raws li thawj load - seem}}}}}}} huab cua (ntxiv thaj chaw siv) thaum txo cov txheej txheem kev coj ua. Qhov no ua rau nws haum tshwj xeeb rau super {{10} high-} Cov tsev siab tshaj plaws (piv txwv li cov tsev nyob hauv qhov siab) qhov chaw txo qis thiab qhov chaw siv hluav taws xob.
Pab Txhawb Cov Tswv Cuab: Hauv cov tsev nrog cov seismic fortifications, Q345B yog siv raws li kab pheeb ces kaum kev sib tsoo ntawm cov thav duab thiab raws li shear wall ntug cov tswv cuab. Nws cov zoo heev thiab cuam tshuam kuj txhim kho cov qauv muaj peev xwm tiv thaiv kev vau zuj zus hauv seismic thauj khoom.
2.What yog cov kev siv q235b hauv loj-} ntev dua qub tsev?
Ru tsev qauv: Piv txwv muaj cov qauv qub tsev trusses, thiab cov tsev hais plaub hauv chaw ua luam dej), cov tsev ua luam dej), cov chaw ua luam dej, thiab cov chaw ua luam dej. Piv txwv li, siv Q345B steel rau lub ntsiab kab ntawm loj {4} {% {{{} Kev tswj hwm cov kabmob hlau thiab deflection kev tswj hwm rau cov loj.
Choj cov qauv (me me rau nruab nrab): thaum siab dua} Tus hlau tsis muaj zog rau hauv cov kab hlau loj (xws li} {{{} Nws yog tsim nyog tshwj xeeb rau cov pej xeem txuas nrog cov vivides tsawg dua lossis sib npaug nrog 30m, muab tus nqi ntau dua {10} {}} kev daws teeb meem.
3.Qhov yog cov ntawv thov ntawm q235b hauv cov vaj tse thiab cov qauv tshwj xeeb?
Lub Hoobkas Cov Qauv: Cov kab hlau crane, kab, thiab vov tsev siv hauv cov cav hnyav, thiab cov nkoj xa khoom. Hauv tshwj xeeb, Q345B steel lub zog siab tau raws li kev qaug zog ua tau raws li kev ua kom muaj kev qaug zog ntau dua 50 tons) hauv crane nqaj tshwm sim los ntawm tsis muaj zog txaus.
Cov qauv tshwj xeeb: steel chimys, dej ntauwd kev tso tsheb hlau loj, piv txwv li cov thawv roj loj (piv txwv li cov khoom muag), thiab cov khoom siv hlau rau kev nqa cov khoom siv. Cov qauv no yuav tsum tau qhib ob qho tib si ntsug loads (piv txwv li, qhov hnyav ntawm lub tank) thiab kab rov tav (piv txwv li, cua loads). Cov cuab yeej siv cov khoom siv tshiab ntawm Q345B hlau ua kom cov qauv kev ruaj khov.
4.What yog cov ntawv teev cov ntaub ntawv tshwj xeeb ntawm Q345b hauv cov khoom sib xyaw ua ke?
Composite Beams: piv txwv, A "Q345b Hlau Beam + Qhob hauv av" sib xyaw. Tus Hlau Beam Dears Tension, Thaum Lub Pob Zeb Ua Pob Zeb Compression. Cov kab teeb no yog qhov haum rau cov kab hauv qab hauv siab {}}} cov kab teeb tsa lossis choj lawj, ntsuas lub zog thiab tus nqi- ua hauj lwm zoo.
Daim Ntawv Sib Sau: Piv txwv, "Q345B steel raj + sab hauv qhob" (qhob {}}}}}}} Rose tsev. Lawv muaj zog ntawm cov hlau siab ntawm cov hlau thiab lub compressive resistance ntawm pob zeb ua kom txhim kho lub load {{tus kabmob muaj peev xwm thiab kev ua seismic.
5.Qhov dab tsi yog cov tseem ceeb ntawm kev siv Q345b hauv tsev qauv?
Cov tub ntxhais tseem ceeb tom qab nws daim ntawv thov yog qhov sib npaug ntawm lub zog thiab tus nqi - ua tau zoo. Piv rau cov pa roj carbon hlau (Q235), Q245b basks siab dua lub zog, enabling me dua hla {4} qhov hnyav, thiab txuag chaw. Piv rau siab dua - muaj zog qis {{}}} alllotic xav tau ntawm feem ntau me me, nruab nrab, thiab vaj tse nruab nrab. Yog li ntawd, nws tau dhau los ua ib qho ntawm feem ntau siv tau tsawg -} cov hlau alleoy hauv tsev qauv.
