NTA
1. Cov Khoom Siv Kho Tshuab Zoo Kawg Nkaus
Muaj zog tiv taus kev khoov: Cov flanges dav thiab tuab nrog lub sijhawm loj ntawm kev sib hloov ntawm inertia (Ix) ua tau zoo dua li I-beams (siab dua 30% -50% ntawm tib qhov hnyav).
Kev Ruaj Ntseg Zoo Kawg Nkaus: Cov flanges yog perpendicular rau lub web, ua rau muaj kev ntxhov siab hauv zos, ua rau lawv tsim nyog rau kev txhawb nqa kem.
Kev Sib Npaug Biaxial Stiffness: X- thiab Y-axis moments of inertia zoo sib xws (piv txwv li, HM hom), ua rau muaj kev tiv thaiv zoo heev rau sab nraud.
2. Nyhav thiab Yooj Yim
Qhov Sib Piv Zog Siab Rau Qhov Hnyav: Sib dua 15% -20% dua li cov I-beams ib txwm rau tib lub peev xwm thauj khoom (txo cov khoom thauj thiab cov nqi hauv paus).
Kev Txuag Khoom Siv: Kev ua haujlwm zoo ntawm qhov txiav siab txo qhov kev siv hlau (piv txwv li, rau lub tsev Hoobkas 30-meter, H-beams siv hlau tsawg dua 40% dua li cov beams pob zeb).
3. Kev Tsim Kho Yooj Yim thiab Ua Tau Zoo
Yooj Yim Bolting: Qhov flange tiaj tiaj ua rau muaj zog bolting.
Txo Kev Vuam: Cov khoom txheem tau ua tiav hauv lub Hoobkas, ua rau kev sib dhos sai dua ntawm qhov chaw (txo lub sijhawm tsim kho los ntawm 30%).
4. Cov Qauv Txheem Siab Tshaj Plaws Cross-Sectional
Tus Txheej Txheem Hauv Tebchaws (GB/T 11263): HW (flange dav), HM (flange nruab nrab), thiab HN (flange nqaim) series, npog qhov ntau thiab tsawg ntawm 100 × 100 txog 1000 × 300 hli.
American Standard (ASTM A36): Cov W series (piv txwv li, W12 × 30) yog lees txais thoob ntiaj teb.
KEV TSHAWB XYUAS KHOOM
Cov kev cai rau kev tshuaj xyuas hlau H-zoo li feem ntau suav nrog cov hauv qab no:
Qhov Tsis Zoo Ntawm Qhov Chaw
Tsis pub:

Cov qhov xeb uas cuam tshuam rau lub zog (qhov tob ntau dua 5% ntawm phab ntsa tuab);
Kev tshem tawm cov txheej zinc (rau cov qauv uas tiv taus xeb).
Cov teeb meem me me uas raug tso cai:
Cov khawb hauv zos ≤ 0.2 hli tob;
Thaj chaw cim ≤ 1cm²/m².
DAIM NTAWV THOV KHOOM
Cov qauv sab nraud H-beams siv dav hauv kev tsim kho thiab kev tsim kho vaj tse, suav nrog tab sis tsis txwv rau cov hauv qab no:
Kev tsim kho vaj tse, kev tsim choj, kev tsim khoom siv tshuab, kev tsim nkoj, kev tsim kho hlau,
NTIM THIAB XA KHOOM
Kev ntim khoom thiab kev thauj mus los ntawm cov qauv sab nraud H-beams feem ntau yuav tsum ua raws li cov kauj ruam hauv qab no:
Kev Ntim Khoom: Cov hlau zoo li H feem ntau yog ntim raws li cov neeg siv khoom xav tau los tiv thaiv nws qhov chaw ntawm kev puas tsuaj. Cov txheej txheem ntim khoom feem ntau suav nrog kev ntim khoom liab qab, ntim ntoo pallet, ntim yas, thiab lwm yam. Thaum ntim khoom, nws yog qhov tsim nyog los xyuas kom meej tias qhov chaw ntawm cov hlau zoo li H tsis khawb lossis xeb.
Kev Sau Npe: Kos cov ntaub ntawv khoom kom meej rau ntawm lub ntim khoom, xws li tus qauv, qhov tshwj xeeb, qhov ntau, thiab lwm yam, kom yooj yim txheeb xyuas thiab tswj hwm.
Kev Thauj Khoom: Thaum thauj khoom thiab thauj cov hlau H-puab uas tau ntim, nws yog qhov tsim nyog los xyuas kom meej tias yuav tsis muaj kev sib tsoo lossis kev tawm thaum lub sijhawm thauj khoom kom tsis txhob muaj kev puas tsuaj rau cov khoom.
Kev Thauj Mus Los: Xaiv cov cuab yeej thauj mus los uas tsim nyog, xws li cov tsheb thauj khoom, kev thauj mus los ntawm tsheb ciav hlau, thiab lwm yam, thiab xaiv txoj kev thauj mus los uas tsim nyog raws li cov neeg siv khoom xav tau thiab qhov deb ntawm kev thauj mus los.
Kev Tshem Tawm: Tom qab tuaj txog ntawm qhov chaw mus, kev tshem tawm yuav tsum tau ua kom zoo kom tsis txhob muaj kev puas tsuaj rau cov hlau H-puab.
Kev Khaws Cia: Khaws cov hlau zoo li H rau hauv qhov chaw qhuav thiab muaj cua nkag kom tsis txhob muaj dej noo lossis lwm yam teeb meem tsis zoo.
