American- Txheem channel steel hlau (American c- channel {}} AISS AISS)
1. Cov ntsiab lus
American- Txheem channel yog hais txog c} Cov miv nyam}}}}}} zoo li kev coj ua thiab aws / aws / aw / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / t / вsm system. Cov channel no yog tsim nyob rau hauv ib thaj tsam ntawm qhov tob, flange dav thiab siv ntau cov tswv cuab cov qauv, tshuab sib xyaw, cov seem muaj qhov xav tau yog qhov tsim nyog.
2. Cov Qauv Siv Tau & Cov Ntaub Ntawv
Cov Qauv & Cov Ntaub Ntawv:kev tsim qauv thiab xaiv cov khoom siv feem ntauAISC STEES kev kho phau ntawvRau ntu cov khoom thiab cov ntxhuav tsim. Cov Qauv Txuj Ci / Tshuaj / Neeg Kho Mob yog cov qauv khoom siv Astm (cov qauv hauv qab no).
Koom Haum ASTM Khoom Cov Qeb Khoom: ASTM A36, ASTM A572 (GR.50 / GR.55), ATM A992(qhov twg teev), thiab siab dua - muaj zog HSLA qib raws li yuav tsum tau ua. Stainless thiab corrosion {-} tiv taus alloys tseem muaj nyob ntawm kev thov.
Nco tseg:Thaum kev yuav khoom lossis kev tsim qauv, qhia txog cov ATTM / AISC Tsim lossis qhov ntev (tob × Flange × Web / Thickness) thiab cov ntaub ntawv yuav tsum tau kuaj.
3. Geometry & Raug Ranges
Qhov tob (H):feem ntau los ntawm hais txog2 hauv (50 hli)mus txog20 hauv (500 hli)Rau cov ntu ntu - Chaw tsim khoom / zeb tuam ntxhab / zeb cov rooj chaw tsim khoom / zeb teev cia qhov ntau thiab tsawg.
Flarh Dav (B):Cov Khoom Nquag Yog1.25 hauv → 6+ hauv (30 hli → 150+ hli).
Lub Vev Xaib & Flange Thickness (Tw / Tf):Txawv los ntawm ntu thiab chav kawm (taws teeb → hnyav) {}}}} ntawm ~ 075 hauv (19 mm) lossis ntau dua nyob rau ntu hnyav.
Cov Ntawv:Kub - rolled channels (los ntawm chapered flanges), rau cov kauj ruam / welded / welded - txheem qhov ntau thiab tsawg.
Ntev:zeb ntev (feem ntau 20 ft / 40 ft / kev cai) lossis txiav {{2} {{ntev; Cov rooj sib tham sib dhos kom ntev dua.
4. Tshooj Khoom Siv & Yuav Siv Li Cas
Official Aisc cov rooj muab qhia meej: Hla} qhov chaw seem, ib lub sij hawm ntawm inertia (sx, sy), vojvoog ntawm gyration thiab chav phaus. Siv cov kev cai no rau lub zog, kev ruaj khov thiab deflection tshev.
Kev kwv yees loj (metric / Imperial):Pawg ≈ ≈ cheeb tsam × li 7,850 kg / mg / mg / mg) lossis siv cov chav tsev hnyav los ntawm AISC lub rooj (LB / FT) rau cov qauv logistics.
Tswv yim:Ib txwm siv cov AISC / ASTM lub rooj nkag mus thaum ua cov txheej txheem txheej txheem kev suav {}} mantse mantsry (fillets, tapered flanges) cuam tshuam rau ix thiab sx.
5. Tus cwj pwm coj cwj pwm & Tsim Qauv
Qhib, asymmetric tshooj:Raws muaj txiaj ntsig zoo rau khoov txog lawv cov kab mob muaj zog (flanges oriented los ntawm kev khoov thiab asymmetric khoov - torsional buckling thiab warping.
Pairing / rov qab - rau -} rov qab siv:Ob tug charnel bolted los yog welded rov qab - {1} rov qab los tsim cov kev coj ua zoo ib yam li) thiab txhim kho kev coj tus cwj pwm zoo li tus cwj pwm.
Kev txhawb zog hauv zos:Ntawm lub zog tsim tawm (crane log, bearings, cov ntawv txuas hnyav) ntxiv cov paib flange, cov phiaj hlau lossis web stiffeners.
Serviceability:Tshawb xyuas cov kev txwv deflection (L / 240, L / 360 lossis kev yuav tsum tau ua) thiab kev co yog siv raws li kev sib tw nrog cov plag tsev lossis purlins.

11. Xaiv & Tsim Kev Tshawb Xyuas (Cov Lus Qhia Ua Tswv Qhia)
Siv AISC cov rooj noj mov rau ntu ntu thiab Inertia; Tsis txhob hloov los ntawm geometry ib leeg yog tias muaj tseeb ix / sx yuav tsum muaj.
Rau cov tsheb ciav hlau ntev ntev muab cov kab xev tom qab lossis xav txog kev sib tw ua ke / lub thawv.
Qhov twg muaj lub zog tsim nyog muaj, nthuav dav flange cov doublers lossis cov paib coj los ua kom tsis txhob yauv tawm.
Yog tias corrosion kuj yuav tsum tau, npaj txheej ntawm theem fabrication theem (galvanize ua ntej mus ua tau los yog siv duplex tom qab fabrication).
Txheeb xyuas Weldability / Kev Kho Cua sov txwv thaum xaiv siab dua - muaj zog HSLA cov hlau.
12. Vim li cas xaiv Asmeskas -} Cov qauv ntsuas?
Lawv tau ua qauv, thiab txhawb nqa los ntawm cov ntaub ntawv dav dav uas muaj rau peb xyaum thiab cov haujlwm thoob ntiaj teb uas hu tawm ntawm cov khoom siv AISC / ASTM cov khoom siv tshuab.
Yog tias koj xav tau, Kuv tuaj yeem:
pubAisc lub rooj nkagthiab ntu ntu (thaj tsam, qhov hnyav ib txhais ko taw, ix, sx) rau cov npe AISC cov kev tsim qauv koj muab rau kuv; lossis
coj kojSPAN + LOADthiab tshaj tawm2-3 Aisc Channel Sib Twnrog kev puas yog kev puas yog khoov thiab deflection tshev (kwv yees).
Qhia kuv qhov kev xaiv uas koj xav tau thiab muab cov qauv channel lossis cov ntaub ntawv luv / load.
