Peb Q235, Q345, A36, S235jr, S355jr, thiab Ss400 Structural H Beams sawv cev rau ntau yam ntawm siab - kev ntseeg siab ntawm cov qauv, tsim kom ua raws li ntau yam thoob ntiaj teb thiab cheeb tsam steel qauv. Cov khoom lag luam no suav nrog cov qauv siv dav dav- suav nrog Tuam Tshoj tus qauv GB / T (Q235, Q345), Asmeskas tus qauv ASTM (A36), Tebchaws Europe tus qauv EN (S235jr, S355jr), thiab Nyij Pooj tus qauv JIS (Ss400){{15} kev ua haujlwm rau kev tsim kho thoob ntiaj teb. Txhua qib yog tsim los ua tib zoo xyuas kom ntseeg tau tias cov khoom siv sib xws thiab qhov ntsuas qhov tseeb, ua lub hauv paus rau kev nyab xeeb thiab ruaj khov cov txheej txheem.
Raws li cov txheej txheem steel hlau, cov qib H beam no tau txhais los ntawm lawv cov kev ua haujlwm kho kom haum kom haum rau ntau yam kev thauj khoom -cov kabmob scenarios. Q235 thiab S235jr, raws li carbon structural steels, muaj qhov tsawg kawg nkaus yield zog ntawm 235 MPa, muab zoo heev ductility thiab formability rau dav - lub hom phiaj daim ntaub ntawv. Q345 (sib npaug rau S355jr) thiab S355jr, cais raws li siab- lub zog qis- alloy (HSLA) steels, khav theeb yam tsawg kawg nkaus lub zog ntawm 345 MPa thiab 355 MPa feem, xa cov khoom txhim khu kev qha-cov kabmob hnyav rau nruab nrab 1. A36, siv dav siv ASTM tus qauv carbon steel, muaj qhov tsawg kawg nkaus lub zog ntawm 250 MPa thiab zoo dua weldability, thaum Ss400, JIS tus qauv carbon steel, muaj kev ruaj ntseg tensile zog (400-510 MPa) thiab versatility rau ntau yam kev xav tau kev tsim kho.
Lub iconic H-zoo li tus ntoo khaub lig- ntu ntawm cov kab teeb no - suav nrog ob qho tib si flanges thiab lub vev xaib nruab nrab- tau ua kom zoo rau kev ua haujlwm zoo. Cov flanges zoo tiv thaiv kev nyuaj siab khoov, thaum lub vev xaib muaj txiaj ntsig zoo tuav lub zog shear, kom ntseeg tau tias muaj kev ntxhov siab zoo sib xws thoob plaws cov khoom. Qhov kev tsim qauv geometric no tso cai rau txhua qib (Q235, Q345, A36, S235jr, S355jr, Ss400) nrog lub zog tshwj xeeb- rau - qhov hnyav piv, txo qhov hnyav tag nrho ntawm cov qauv yam tsis muaj kev cuam tshuam cov qauv kev ncaj ncees. Tsis tas li ntawd, cov H beams no nthuav dav weldability thiab machinability zoo, ua kom yooj yim fabrication, ntawm -qhov chaw teeb tsa, thiab kev kho kom haum raws li cov qauv tsim tshwj xeeb ntawm ntau yam haujlwm.
Kev ua haujlwm dav dav hauv kev tsim kho thoob ntiaj teb thiab kev tsim kho vaj tse, cov qauv H beams yog qhov kev xaiv zoo tshaj plaws rau cov tsev lag luam, cov tsev khaws khoom lag luam, txuas hniav, chaw ntau pob, cov chaw tsim hluav taws xob, thiab cov chaw thauj mus los. Q235, A36, S235jr, thiab Ss400 yog qhov zoo tagnrho rau cov qauv txheej txheem xws li cov kab hauv pem teb, lub ru tsev russes, thiab lub teeb -cov haujlwm txhawb nqa. Piv txwv li, Q345 thiab S355jr tshwj xeeb tshaj yog haum rau hnyav- daim ntawv thov kev ua haujlwm, suav nrog - txuas txuas loj, siab - nce lub tsev cores, thiab cov cuab yeej siv hauv tsev, uas muaj zog dua thiab qaug zog kuj tseem ceeb heev. Tag nrho peb cov H beams tau dhau los ua cov txheej txheem kev tswj hwm nruj, suav nrog tshuaj lom neeg kev tshuaj ntsuam xyuas, kev ntsuas cov cuab yeej cuab yeej (tensile, dabtsi yog khoov, cuam tshuam), thiab kev tshuaj xyuas qhov ntev, kom ntseeg tau tias ua tau raws li lawv cov qauv kev cai.
Hauv cov ntsiab lus, peb Q235, Q345, A36, S235jr, S355jr, thiab Ss400 Structural H Beams muaj ntau yam, txhim khu kev qha, thiab cov qauv- ua raws li kev daws teeb meem rau ntiaj teb kev tsim qauv engineering. Los ntawm kev npog tag nrho cov qib ntawm cov khoom siv thiab ua raws li cov qauv zoo thoob ntiaj teb, cov khoom siv no txhawb cov kws tsim qauv, cov kws tsim qauv, thiab cov neeg cog lus kom paub txog cov phiaj xwm sib txawv ntawm cov nplai thiab qhov nyuaj, nrog rau kev ruaj ntseg, durability, thiab tus nqi - ua tau zoo.
