Piv nrog rau cov qauv ntawm lwm cov ntaub ntawv, cov qauv steel muaj cov yam ntxwv hauv qab no:
1. Cov qauv steel yog lub teeb hauv qhov hnyav
Txawm hais tias qhov ntom ntom ntawm cov qauv hlau loj, nws lub zog yog ntau dua li ntawm lwm cov khoom siv hauv tsev. Yog li ntawd, thaum lub load thiab tej yam kev mob yog tib yam, lub steel qauv yog sib dua li lwm yam qauv, uas yog yooj yim rau kev thauj mus los thiab installation, thiab yuav span ntau loj. Qhov hnyav ntawm lub tsev tsim nrog cov qauv hlau yog li 1/2 ntawm cov pob zeb ua vaj tse; nws tuaj yeem ua tau raws li qhov xav tau ntawm chav loj ntawm lub tsev, thiab thaj chaw siv yog li 4% siab dua li ntawm lub tsev ua vaj tse.
2. Zoo plasticity thiab toughness ntawm hlau
Ntawm lawv, cov yas yog qhov zoo, yog li cov qauv hlau feem ntau tsis tawg tam sim ntawd vim kev sib tsoo los yog cov khoom siv hauv zos. Zoo toughness ua rau cov qauv steel ntau yoog mus rau dynamic loads. Cov khoom ntawm cov hlau no muab kev lees paub txaus rau kev nyab xeeb thiab kev ntseeg siab ntawm cov qauv steel.
3. Hlau yog ze rau ib homogeneous thiab isotropic lub cev
Cov qauv sab hauv ntawm cov hlau yog qhov sib xws, ze heev rau lub cev homogeneous thiab isotropic, thiab yuav luag tag elastic nyob rau hauv ib qho kev ntxhov siab ntau. Cov khoom no yog nyob rau hauv txoj kab nrog cov kev xav hauv lub tshuab xam zauv, yog li cov txiaj ntsig ntawm cov qauv steel muaj ntau dua nyob rau hauv txoj kab nrog qhov tseeb qhov kev ntxhov siab.
4. huab cua nruj thiab dej nruj ntawm cov qauv hlau zoo dua
5. tus qauv tsim yog hloov tau thiab nplua nuj
Nrog tib lub nqaj qhov siab, lub bay ntawm cov qauv hlau tuaj yeem yog 50% loj dua li qhov chaw ntawm lub pob zeb, yog li ua rau lub tsev kho kom zoo dua qub.
6. kev tsim steel qauv yog yooj yim
Kev tsim kho thiab kev teeb tsa lub sijhawm luv luv, thiab cov qauv steel yog tsim los ntawm ntau yam profiles, uas yooj yim rau kev tsim khoom. Ntau tus qauv steel yog tsim nyob rau hauv tshwj xeeb hlau qauv fabrication nroj tsuag; siab precision. Cov khoom tsim tau raug thauj mus rau qhov chaw rau kev sib dhos, thiab txuas nrog bolts. Cov qauv yog lub teeb, yog li kev tsim kho tau yooj yim thiab lub sijhawm tsim kho yog luv. Tsis tas li ntawd, cov qauv steel ua tiav tuaj yeem yooj yim dismantled, ntxiv dag zog lossis rov ua dua tshiab.
7. kev siv cov qauv hlau tuaj yeem tiv thaiv ib puag ncig zoo
Nws yog embodied nyob rau hauv peb yam: ua ntej, piv nrog rau cov pob zeb, qhuav siv tau, uas ua rau tsis muaj suab nrov thiab plua plav; Thib ob, vim qhov txo qis tus kheej qhov hnyav, cov av qiv nyiaj rau kev tsim kho hauv paus yog me me, thiab kev puas tsuaj rau cov khoom siv av me me. Kev noj cov pob zeb tuaj yeem txo qhov kev khawb thiab khawb, uas muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig ecological; thib peb, tom qab lub neej kev pab cuam ntawm lub tsev qauv tas sij hawm, tom qab cov qauv yog demolished, tus nqi ntawm cov khoom pov tseg generated yog me me, thiab cov nqi ntawm cov khoom seem ntawm cov khoom siv rov qab yog siab.
8. High degree ntawm industrial ntau lawm ntawm steel qauv
Nws yog qhov yooj yim rau kev tsim cov tshuab, siv ntau lawm, siab precision, yooj yim installation, thiab yooj yim kev ruaj ntseg. Nws tuaj yeem tsim tau rau hauv lub tsev tsim khoom tiag tiag, kev tsim khoom tsim choj, kev tsim cov khoom siv cog qoob loo, thiab lwm yam. Kev tsim cov qauv steel tau tsim thiab tsav kev loj hlob ntawm ntau pua kev lag luam tawm tshiab.
Qhov zoo ntawm H-beams
H-beam yog ib hom tshiab ntawm kev siv nyiaj txiag siv hlau. Cov duab ntawm H-beam yog kev lag luam thiab tsim nyog, thiab cov khoom siv kho tshuab zoo. Thaum lub sij hawm dov, cov ntsiab lus ntawm ntu txuas ntxiv sib npaug thiab qhov kev ntxhov siab sab hauv me me. Piv nrog rau qhov zoo tib yam I-nqaj, nws muaj qhov zoo ntawm qhov loj seem modulus, lub teeb yuag thiab txuag hlau; Sab hauv thiab sab nraud ntawm ob txhais ceg yog sib npaug, thiab ob txhais ceg yog nyob ntawm txoj cai kaum. Lawv tuaj yeem sib sau ua ke rau hauv cov khoom, uas tuaj yeem txuag cov vuam thiab riveting workload los ntawm 25%. Nws yog feem ntau siv hauv cov tsev loj (xws li kev cob qhia, cov tsev siab siab, thiab lwm yam) uas yuav tsum tau muaj peev xwm loj thiab muaj kev ruaj ntseg zoo, nrog rau cov choj, nkoj, nqa thiab tsheb thauj mus los, cov cuab yeej siv hauv paus, kev txhawb nqa, pawg hauv paus, lwm.
H-beams feem ntau yog siv rau hauv cov nroj tsuag, pej xeem vaj tse, engineering engineering, roj platforms, txuas hniav, flatbed girders, lub hwj chim txhawb rau electrified railways, thiab steel qauv choj raws railways. Lub teeb thiab ultra-light H-beams yog qhov tsim nyog rau kev tsim cov thawv ntim khoom, lub tsev txawb, ntau lub chaw nres tsheb, lub thawv tsheb ciav hlau, kev txhawb nqa hluav taws xob, ntau qhov chaw, thiab cov tsev me me.
Qhov kub-dov H-beam tsim nyog faib cov nam piv ntawm ntu loj raws li kev siv sib txawv, thiab muaj cov khoom siv zoo heev thiab kev ua haujlwm zoo heev.
Cov qauv tsim muaj zog. Piv nrog I-beam, seem modulus yog loj, thiab cov hlau yuav cawm tau los ntawm 10-15% nyob rau hauv tib lub load-bearing tej yam kev mob.
Cov qauv yog lub teeb hauv qhov hnyav. Piv nrog rau tus kheej qhov hnyav ntawm cov pob zeb ua qauv, nws yog sib dua, thiab qhov txo qis ntawm tus kheej qhov hnyav ntawm cov qauv txo qhov kev quab yuam sab hauv ntawm cov qauv tsim, uas tuaj yeem ua rau cov kev kho mob yooj yim ntawm cov qauv hauv tsev, kev tsim kho. yog qhov yooj yim, thiab tus nqi txo.
H-beam-raws li steel qauv muaj kev tshawb fawb thiab tsim nyog qauv, zoo plasticity thiab yooj, siab structural stability, thiab siab structural stability. Kev tsim vaj tsev nyob hauv qee thaj tsam av qeeg. Raws li kev txheeb cais, ntawm cov av qeeg loj heev ntawm qhov loj 7 lossis siab dua hauv ntiaj teb, cov tuam tsev hlau uas muaj H-beams raug kev puas tsuaj tsawg kawg nkaus.
Txhim kho qhov siv tau zoo ntawm cov qauv. Piv nrog rau cov qauv kev ua vaj tse, qhov chaw hla ntawm cov qauv steel kem yog me me, uas tuaj yeem ua rau thaj tsam siv tau zoo ntawm lub tsev. Nyob ntawm cov ntaub ntawv sib txawv ntawm lub tsev, thaj chaw siv tau zoo tuaj yeem nce los ntawm 4-6%.
Nws tuaj yeem pom tseeb txuag kev ua haujlwm thiab cov khoom siv, thiab txo qis kev noj cov khoom siv raw, lub zog thiab kev ua haujlwm.
Ib qho yooj yim machining, cov qauv kev sib txuas thiab kev teeb tsa, thiab yooj yim tshem tawm thiab rov siv dua.
Kev tsim kho ntawm qhov project yog ceev ceev, hauv pem teb cheeb tsam yog me me, thiab nws yog haum rau tag nrho cov huab cua kev tsim kho thiab tsis tshua muaj kev cuam tshuam los ntawm climatic tej yam kev mob. Kev tsim kho ceev ntawm cov qauv hlau ua los ntawm H-nqaj yog kwv yees li 2-3 lub sijhawm ntawm kev tsim kho ceev ntawm cov qauv kev tsim vaj tsev, cov peev nyiaj tau los yog ob npaug, tus nqi nyiaj txiag raug txo, thiab kev nqis peev tau txais kev cawmdim. Noj "Jinmao Building" nyob rau hauv Pudong, Shanghai, kuv lub teb chaws "lub tsev siab tshaj" raws li piv txwv, cov qauv saum toj kawg nkaus ntawm cov qauv nrog lub cev loj ntawm ze li ntawm 400m tau ua tiav nyob rau hauv tsawg tshaj li ib nrab xyoo, thaum lub steel-concrete qauv yuav tsum tau. lub sijhawm tsim kho ob xyoos.
