Peb Txheem H - Beams (ASTM W / S / m
Tsim thiab qhov loj me:
US W {- duab: ua ntej ua ntej dav dav thiab cov webs siv nyias rau khoov kev ua tau zoo. W18 × 76 (18-nti qhov siab) muaj lub vev xaib flange ntawm 0.425 nti thiab kev ntsuas ntawm kev tsis kam lees) nrog qhov hnyav.
European Heape REA / Heb: Hewb kab teeb tau nqaim flanges thiab tuab tshaj w - duab. Ib tug heb 450 (450 mm qhov siab) muaj cov flange dav ntawm 200 hli thiab lub vev xaib tuab ntawm 11 hli, tsim rau balanced axial thiab dabtsi yog khoov. Heb kab teeb ciav hlau tau hnyav dua rau ib qho ntev tshaj li we{ [} hier 43}} He}} Cov duab Axis muaj zog tab sis nws yog khoov kev ua tau zoo.
Japanese jis h - Beams: JIS G3192 Qhia Txog Qhov Me Me Flanges Ntau Tshaj W}} Duab tab sis dav dua li hea. Ib 450 × 200 jis h- tsov ntxhuav (450 hli qhov siab) muaj lub vev xaib tuab ntawm 9 hli, ntsuas lub zog thiab kev siv hluav taws xob. Lawv tau sib dua tshaj ob qho W thiab Heb Shape - 450 × 4 Kg / M-M-Haum rau lub teeb yuag.
Cov Khoom Siv Neeg Kho Tshuab:
Tos lub zog ntau:
Us: A36 (250 MPA), A572 Qib 50 (345 MPa), A992 (345 MPA).
European: S235 (235 MPa), S355 (355 MPA), S460 (460 MPA).
Japanese: SS400 (245 MPA), SM490 (325 MPA).
Cov kev kawm nyob hauv European muaj ntau dua qhov ua tau zoo tshaj plaws (S460> A992 tau zoo dua qub (-40 Qib F cuam tshuam kev xeem), tseem ceeb rau huab cua txias.
Weldability: Asmeskas A36 (0.26% Cax) thiab European Version (0.23% ntawm -}} chaw vuam.
Daim Ntawv Thov Xyuas:
Peb w - duab: Excel nyob rau hauv khoov - Cov duab kab teeb, Roos mom, Roos Girders) vim yog qhov dav. Nyiam nyob rau hauv North America rau cov tsev lag luam lag luam, cov choj, thiab spans ntau dua 30 feet.
European Heape REA / HEB: Zoo dua rau cov roj axial (kab) vim tuab. Siv nyob rau hauv European siab-}} sawv thiab cov nroj tsuag, qhov twg sib zog ua pa thiab muaj cov roj muaj axial muaj ntau.
Japanese jis h - Beams: Zoo tagnrho rau cov qauv kev coj seones (lawv qhov hnyav me, lawv qhov hnyav txo qis hauv av hauv av.
Tus nqi thiab muaj:
Teb chaws Asmeskas: Tus nqi qis hauv North America thiab Latin America vim yog kev tsim khoom hauv tsev. Txawv teb chaws mus rau Asia / Middle East ntawm 10-15% hwm tshaj hauv cov kab hauv zos.
European: Txawv hauv EU nrog qis - cov nqi thauj khoom hauv cheeb tsam. Teb chaws txawv teb chaws Africa ntawm cov nqi siab dua vim EU export cov khoom.
Japanese: Nqis nyob rau hauv Asia tab sis kim nyob rau Western lag luam vim tias xa khoom thiab cov haujlwm.
Code kev sib xyaw:
Cov nqaj hlau ua ke nrog AISC 360, tsom mus rau ntawm cov thauj khoom thiab kev tawm tsam tsim nyog (LRFD).
Cov kab av hauv European siv Eurocode 3, hais txog lub xeev tsim nrog stricter rog rog.
Japanese Beams Ua raws li Aij cov lus qhia txog AIJ, nrog kev txhim kho seismic (piv txwv li, txo flange dav {}} tuab ratios).
Kev Kawm Kev Kawm: Ib 30 {14 {14- ko taw siv ib qho W16 × 57 A5 5 PSF nyob rau 50 PSF Live Tib lub tebchaws nyob rau hauv cov chaw lag luam German tau siv HEX 400 s355 nqaj (400 lub qhov siab siv 400 × 200 nqaj (SS400) rau kev tsim lub ntsej muag.
Hauv kev xaus, peb cov qauv kev sib tw h {Beams Excel nyob rau hauv khoov {} {- tsom rau cov cheeb tsam uas muaj lub hauv paus av engineing.
