Lub Teeb Channel Hlau (Lub Teeb C- channel / lub teeb u - channel)
1. Cov ntsiab lus
Lub teeb Channel Steel yog yig c -}} zoo li cov steel cov tswv cuab nrog qhov tob me me thiab nyias cov webs / flanges. Lawv tsim los rau lub teeb {{4 4}} cov qauv siv, kev lag luam tseem ceeb, kev lag luam luas
2. Cov ntaub ntawv raug & qib
Cov Hlau Roj Hlau:Q195 / Q235 / S235 / A 36 - tus nqi qis, yooj yim rau weld thiab dav thiab dav muaj.
Siab dua - tawm cov kev xaiv (yog tias yuav tsum tau):S275 / S355 / A572 GR.50.
Corrosion -} Cov kev xaiv tiv thaiv:Kub - dip galvanized (HDg), electro {} galvalumized, los yog stainless (304/316) rau ib puag ncig kev txhoj.
Daim Ntawv Xaiv:Kub -}} {{- Tsim (los ntawm coil) rau kev tsim lub teeb (los ntawm cov teeb tsa
3. Cov neeg geometry & ranges (chav kawm lub teeb)
Qhov tob (H):feem ntau40 hli → 140 hli(Ntau qhov ntau thiab tsawg: 50, 65, 75, 100 hli).
Flarh Dav (B): 25 hli → 50 hli.
Web tuab (tw): 2.5 hli → 6 hli.
Flange Thickness (TF): 3 hli → 8 hli.
Ntev:Txiav -} rau {{1} ntev los ntawm coil / Tshuag (nquag 3 m; zeb ntev sib txawv ntawm qhov chaw).
Chav phaus:Lub teeb nyob ib txwm muaj los ntawm~ 2 kg / m rau ~ 18 kg / mnyob ntawm seem.
4. Yuav ua li cas kwv yees thaj chaw & qhov hnyav
Kwv yees thaj tsam (mM²):
A ≈ 2 × (b × TF) + (H - 2 × TF) × tw
Pawg ib meter meter (kg / m):
Mass=A (mm²) × 0.00785 (Hlau Density ≈ 7,850 kg / mp / mp / m³)
Tus yam ntxwv(checked kauj ruam - - mm, tf=4 mm, ntxiag {{mm
Flange cheeb tsam txhua=40 × {{1} → 2 flanges=320 mm²
Lub Web Qhov Siab=100}} {{4=92 mm} {{{4 4 4 4 4 4 4 4 {
Tag nrho cheeb tsam=320 + 368=688 mm²
Mass=688 × 0.00785=5.399 ≈5.40 kg / m
Siv cov ntawv teev ntu rau tsim tsim - tseem ceeb ix, iy thiab sx, sy muaj nuj nqis.
