cov qauv hlau-qauv-qhia-4 (1)

Cov qauv hlau tsim khosiv hlau ua lub hauv paus tseem ceeb rau kev thauj khoom (xws li cov ntoo khaub lig, cov kem, thiab cov trusses), ntxiv los ntawm cov khoom tsis thauj khoom xws li cov pob zeb thiab cov ntaub ntawv phab ntsa. Cov txiaj ntsig tseem ceeb ntawm hlau, xws li lub zog siab, lub teeb yuag, thiab kev siv rov qab tau, tau ua rau nws yog ib qho thev naus laus zis tseem ceeb hauv kev tsim vaj tsev niaj hnub, tshwj xeeb tshaj yog rau cov tsev loj, cov tsev siab, thiab cov tsev lag luam. Cov qauv hlau tau siv dav hauv cov chaw ua si, cov chaw ua yeeb yam, cov tsev siab siab, cov chaw tsim khoom, cov choj, thiab lwm yam kev siv.

Cov Qauv Tseem Ceeb

Yuav tsum xaiv cov qauv ntawm lub tsev hlau raws li lub luag haujlwm ntawm lub tsev (xws li qhov ntev, qhov siab, thiab qhov hnyav). Cov hom uas feem ntau yog raws li nram no:

Daim Ntawv Qauv Lub Ntsiab Cai Tseem Ceeb Cov Xwm Txheej Siv Tau Cov Ntaub Ntawv Ib Txwm Muaj
Cov Qauv Ncej Ua los ntawm cov ntoo thiab cov kem txuas nrog los ntawm cov pob qij txha khov kho lossis cov pob qij txha sib txuas ua ke los tsim cov thav duab tiaj tiaj, uas dais tau cov khoom thauj ntsug thiab cov khoom thauj kab rov tav (cua, av qeeg). Cov tsev ua haujlwm ntau txheej/siab, tsev so, chav tsev (feem ntau nrog qhov siab ≤ 100m). Tuam Tshoj Lub Tsev Lag Luam Thoob Ntiaj Teb 3B (ib feem ntawm lub thav duab)
Cov Qauv Truss Muaj cov khoom ncaj (piv txwv li, hlau kaum sab xis, hlau puag ncig) ua cov duab peb ceg. Nws siv qhov ruaj khov ntawm cov duab peb ceg los hloov cov khoom thauj, kom ntseeg tau tias muaj kev faib zog sib npaug. Cov tsev loj (ntev: 20-100m): chaw ua si, chaw ua yeeb yam, chaw ua haujlwm hauv Hoobkas. Lub ru tsev ntawm National Stadium (Noog's Nest)
Qhov Chaw Truss / Lattice Shell Structure Tsim los ntawm ntau tus tswv cuab uas tau teeb tsa ua tus qauv ib txwm (piv txwv li, cov duab peb sab sib npaug, cov duab plaub fab) rau hauv ib daim phiaj xwm chaw. Cov zog tau faib ua qhov chaw, ua rau muaj thaj chaw loj. Cov tsev loj heev (ntev: 50-200m): cov chaw nres tsheb hauv tshav dav hlau, cov chaw sib tham. Ru tsev ntawm Guangzhou Baiyun Tshav Dav Hlau Terminal 2
Lub Rooj Sib Tham Rigid Ncej Ua los ntawm cov ncej thiab cov ntoo uas ruaj khov los ua ib lub thav duab zoo li "rooj vag". Cov hauv paus ntawm cov ncej feem ntau yog hinged, tsim nyog rau kev ris cov khoom hnyav me me. Cov chaw tsim khoom lag luam ib txheej, cov tsev rau khoom, cov chaw xa khoom (ntev: 10-30m). Ib lub Hoobkas tsim khoom ntawm lub Hoobkas tsheb
Cov Qauv Cable-Membrane Siv cov xov hlau muaj zog siab (piv txwv li, cov xov hlau galvanized) ua lub thav duab thauj khoom, npog nrog cov ntaub ntawv membrane hloov pauv tau (piv txwv li, PTFE membrane), muaj ob qho tib si kev xa hluav taws xob thiab lub peev xwm loj. Cov tsev ua vaj tse, cov chaw ua si uas muaj cua txhawb nqa, cov chaw nres tsheb hu xov tooj. Chav Ua Luam Dej ntawm Shanghai Oriental Sports Center

Cov Khoom Siv Tseem Ceeb

Cov hlau siv rau hauvcov tsev qauv hlauyuav tsum tau xaiv raws li qhov yuav tsum tau ua ntawm cov qauv, qhov xwm txheej ntawm kev teeb tsa, thiab kev siv nyiaj tsim nyog. Nws feem ntau yog muab faib ua peb pawg: phaj, profiles, thiab kav dej. Cov pawg me thiab cov yam ntxwv tshwj xeeb yog raws li nram no:

I. Cov Phaj:
1. Cov phaj hlau tuab
2. Cov phaj hlau nruab nrab-nyias
3. Cov phaj hlau uas muaj qauv

II. Cov ntaub ntawv qhia txog tus kheej:
(I) Cov ntaub ntawv kub-kub: Haum rau cov khoom siv thauj khoom tseem ceeb, muab lub zog siab thiab kev tawv
1. I-beams (xws li H-beams)
2. Cov hlau channel (C-beams)
3. Lub kaum sab xis hlau (L-beams)
4. Hlau tiaj tus
(II) Cov ntaub ntawv nyias nyias uas tsim los ntawm cov khoom siv txias: Haum rau cov khoom siv sib dua thiab cov khoom siv kaw, muab qhov hnyav tsawg
1. Cov kab C-kab uas ua los ntawm txias
2. Cov kab Z-kab uas ua los ntawm txias
3. Cov kav dej plaub fab thiab plaub fab uas ua los ntawm cov khoom txias

III. Cov kav dej:
1. Cov kav hlau tsis muaj qhov sib txuas
2. Cov kav hlau vuam

Cov Qauv Hlau Zoo Dua

Muaj Zog, Lub Teeb NyhavLub zog tensile thiab compressive ntawm cov hlau yog siab dua li cov pob zeb ua vaj tse (kwv yees li 5-10 npaug ntawm cov pob zeb ua vaj tse). Vim tias cov kev cai ntawm kev thauj khoom zoo ib yam, cov khoom siv ntawm cov hlau tuaj yeem me dua hauv qhov seem thiab sib dua hauv qhov hnyav (kwv yees li 1/3-1/5 ntawm cov qauv pob zeb ua vaj tse).

Kev Tsim Kho Sai thiab Kev Lag Luam Siab: Cov qauv hlauCov khoom sib xyaw (xws li H-beams thiab lub thawv kem) tuaj yeem ua tus qauv thiab tsim tawm hauv cov chaw tsim khoom nrog qhov tseeb ntawm millimeter. Lawv tsuas yog xav tau bolting lossis vuam rau kev sib dhos ntawm qhov chaw, tshem tawm qhov xav tau lub sijhawm kho zoo li cov pob zeb.

Kev Ua Haujlwm Zoo Kawg Nkaus ntawm Kev Av QeegCov hlau ua tau zoo heev (piv txwv li, nws tuaj yeem hloov pauv tau zoo thaum muaj kev thauj khoom yam tsis tawg tam sim ntawd). Thaum muaj av qeeg, cov qauv hlau nqus tau lub zog los ntawm lawv tus kheej hloov pauv, txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm lub tsev tag nrho.

Siv Chaw NtauCov ntu me me ntawm cov khoom siv hlau (xws li cov kav hlau tubular thiab cov H-beams nqaim-flange) txo qhov chaw uas phab ntsa lossis cov kem nyob.

Ib puag ncig zoo thiab siv tau dua tshiab tau zoo heevCov hlau muaj ib qho ntawm cov nqi rov ua dua tshiab siab tshaj plaws ntawm cov ntaub ntawv tsim kho (ntau dua 90%). Cov qauv hlau uas raug rhuav tshem tuaj yeem rov ua dua thiab siv dua, txo cov khib nyiab tsim kho.
