Cov txheej txheem kev tsim kho ntawm cov tsev steel qauv yog yooj yim, nrog kev ruaj ntseg zoo thiab seismic tsis kam, thiab tau yeej qhov kev lees paub ntawm cov pej xeem. Nyob rau hauv lub era ntawm kev tawm tswv yim ntsuab thiab ib puag ncig tus phooj ywg vaj tse, txawm nyob rau hauv cov cheeb tsam nyob deb nroog los yog hauv nroog, steel qauv kev tsim vaj tsev zoo li tau dhau los ua ib qho kev inevitable.
Steel qauv tsev yog assembled los ntawm ntau yam Cheebtsam. Dab tsi yog cov teeb meem uas yuav tsum tau them sai sai rau thaum tsim steel qauv tsev? Los xyuas kom meej qhov zoo thiab ruaj khov ntawm steel qauv vaj tsev. Niaj hnub no, cia peb tham txog qee yam kev paub txog kev tsim vaj tsev steel qauv ua ke.
1. Txhawm rau kom paub meej qhov kev teeb tsa ntawm tus qauv qub, xaiv qhov tsim nyog txuas txoj haujlwm thiab daim ntawv ntawm cov qauv hlau thiab cov qauv qub, thiab zam kev puas tsuaj rau cov qauv qub los ntawm cov qauv steel loads.
2. Kev teeb tsa ntawm thawj thiab theem nrab steel kab teeb hauv cov qauv steel yuav tsum tau ua ke nrog kev tsim vaj tsev, kho kom zoo nkauj, thiab kev teeb tsa ntawm lub tsev pheeb suab kom tsis txhob los yog txo qis kev puas tsuaj rau cov qauv hlau thaum lub sij hawm kho kom zoo nkauj thiab kev teeb tsa.
3. Nws tsis pom zoo kom siv hollow steel cov ntaub ntawv xws li square steel thiab tube steel, vim nws nyuaj rau siv cov xim pleev xim rau hauv cov hlau. Kev hloov pauv txias thiab kub nyob rau sab qaum teb tuaj yeem ua rau muaj kuab paug thiab xeb ntawm cov hlau, uas tuaj yeem cuam tshuam rau lub qab nthab thiab phab ntsa, thiab ua rau muaj kev phom sij loj heev.
4. Kev npaj ntawm cov qauv steel yuav tsum muaj cov kev faib tawm kom meej thiab meej. Vim yog lub zog tseem ceeb thiab kev co ntawm cov qauv hlau nws tus kheej, kev tshuaj xyuas meej thiab kev suav yuav tsum tau ua, kev tswj xyuas nruj ntawm cov txheej txheem deformation thiab vibration zaus yuav tsum tau ua kom pom kev zoo nkauj ntawm cov qauv, tshem tawm resonance ntawm tus qauv thiab tib neeg kev ua ub no, thiab zam. shear qaug zog puas tsuaj los ntawm resonance phenomena. Tib lub sijhawm, qhov no tuaj yeem ua kom muaj kev nplij siab thaum siv.
5. Rau kev xaiv steel (channel steel, I-beam), peb feem ntau muaj specifications ntawm 10, 12, 14, thiab 16 xaiv los ntawm. Txawm hais tias xaiv qhov tshwj xeeb, nws raug nquahu kom siv "tus qauv hauv tebchaws" steel vim nws cov hlau zoo thiab cov lus qhia tshwj xeeb zoo tshaj rau "tsis yog-tus qauv steel". Cov hlau tsis muaj txheej txheem muaj siab hardness, brittleness, tsis zoo ductility, thiab tsis yooj yim rau txiav los yog xyaum.
6. Ua ntej kho cov channel steel, sab ntawm cov channel steel tiv thaiv phab ntsa yuav tsum tau coated nrog cov tshuaj tiv thaiv xeb, tab sis lwm qhov yuav tsum tau pleev xim rau tom qab vuam, txwv tsis pub nws yuav cuam tshuam rau kev ua haujlwm vuam.
Thaum lub sij hawm tsim cov qauv steel, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ob qho tib si I-beams thiab channel steels yuav tsum muaj tib yam specifications, thiab "tag nrho vuam" yuav tsum tau xaiv. Lub ntsiab keel yuav tsum tau ua los ntawm tag nrho cov hlau, thiab intermediate welding yog nruj me ntsis txwv tsis pub.
Muaj ntau lub hom phiaj ntawm qhov xwm txheej uas cuam tshuam rau cov qauv steel, yog li thaum tsim cov qauv steel, nws yog ib qho tsim nyog los xaiv hom steel qauv thiab ua kom muaj kev tiv thaiv zoo raws li thaj chaw ib puag ncig thiab huab cua. Nyob rau hauv tus txheej txheem ntawm steel qauv installation thiab ntau lawm, txhua kauj ruam thiab cov ntsiab lus yog nyob ze intertwined, yog li cov kws tsim kho yuav tsum muaj lub siab ntev txaus los xyuas kom meej qhov zoo ntawm txhua kauj ruam, thiab thaum kawg xa rov qab mus rau tus tswv hauj lwm raws li ib tug ruaj ntseg thiab txhim khu kev qha lub tsev.
