1. Tub ntxhais sib txawv
| tus yam ntxwv | H-nqaj | I-nqaj |
|---|---|---|
| Flange Tsim | Dav thiab tig mus rau, sib zog ua tuab | Nqaim thiab tapered sab hauv, nrog kev nruj me ntsis |
| Lub Web Thickness | Feem ntau thicker | Qub |
| Lub caij ntawm inertia ntawm thaj chaw | Loj dua (muaj zog tiv thaiv dabtsi yog khoov) | Me |
| qho hnyav | Hnyav dua ntawm tib lub ntev | Lub ntais txhuam |
2. Lub zog sib piv
(1) Dabtsi yog khoov zog (tom qab loader)
Hlau nqaj hlau h muaj zog dua: cov flange ua rau kev cuam tshuam kev ntxhov siab ntau yam zoo nkauj dua, haum rau loj clans (xws li lub Hoobkas loj ci thiab txuas hniav).
Piv txwv li: ntawm qhov hnyav tib yam, kev khoov tsis kam ntawm h nqaj steel qauv yog li 20% ~ 30% siab dua li ntawm I-nqaj.
(2) Lub Zog Compressive (Ntsug Load)
Cov txheej txheem hlau nqaj yog zog heev: lub web tuab thiab flange flange muab cov qauv hlau hluav taws xob ntau dua).
I-nqaj yog nquag mus rau hauv zos buckling thiab xav tau kev ntxiv ntxiv.
(3) torsional lub zog (torsion quab yuam)
Ob qho tsis muaj zog, tab sis kuv-nqaj yog qhov zoo dua; Kev Inclined Flange tsim ua rau I-nqaj muaj qee yam tsis kam mus rau ib qho kev sib tw me me, tab sis hnyav zog yuav tsum tau siv lub thawv.
3. Yuav ua li cas xaiv?
Cov xwm txheej uas H-Shaped Hlau Beam yog nyiam:
Ntev ntev cov qauv (ntau dua los yog sib npaug rau 10 metres)
Cov khoom siv siab (xws li cov khoom siv hnyav thiab txuas hniav)
Vaj tse nrog cov seismic siab
Cov xwm txheej uas kuv-puab hlau yog nyiam:
Lub teeb tsim (xws li lofts nyob ntawm thaj chaw)
Luv luv (<6 meters) secondary beams
Tus nqi them tus nqi
Gnee steel yog lub chaw tsim khoom lag luam h nqaj, ha nqaj muag khoom thiab cov khoom lag luam h nqaj chetal. Peb yog lub tuam txhab nrog 18 xyoo ntawm cov kev tsim khoom thiab tau cog lus los muab H nqaj ntawm ntau cov ntaub ntawv.
Peb tuaj yeem muab cov qauv ha tw, s355jr steel h hom steel nqaj, s355ml hite, a572Pr50r, A992 H zoo li tus hlau thiab lwm yam khoom siv. Peb tuaj yeem hloov kho raws li cov cai tshwj xeeb. Nyob rau tib lub sijhawm, peb kuj tseem tuaj yeem muab cov ntawv pov thawj zoo thiab txais kev tshuaj xyuas thib peb.
