H-beam li I-beam los yog universal steel beam, yog ib qho kev lag luam thiab kev ua haujlwm zoo nrog kev ua kom zoo tshaj plaws hauv cheeb tsam kev faib tawm thiab tsim nyog lub zog-rau-qhov hnyav piv. Nws lub npe los ntawm nws cov duab sib luag zoo ib yam li tsab ntawv Askiv "H".
Kev tsim ntawm cov hlau no ua rau nws muaj kev khoov zoo heev hauv ntau cov lus qhia, thiab tib lub sijhawm, nws yooj yim los tsim, uas tuaj yeem txuag tau cov nqi thiab txo qhov hnyav ntawm cov qauv. Cov ntaub ntawv ntawm H-beam feem ntau muaj xws li Q235B, SM490, SS400, Q345B, thiab lwm yam, uas ua rau H-beam zoo tshaj plaws hauv cov qauv siv zog thiab tsim kom yooj yim. Vim nws qhov dav flange, nyias lub vev xaib, ntau yam kev qhia tshwj xeeb thiab siv tau yooj yim, daim ntawv thov ntawm H-beam nyob rau hauv ntau yam truss qauv tuaj yeem txuag tau 15% txog 20% ntawm cov hlau.
Tsis tas li ntawd, muaj ob txoj hauv kev tseem ceeb rau kev tsim H-beam: vuam thiab dov. Welded H-beam yog tsim los ntawm kev txiav cov sawb rau hauv qhov dav dav thiab vuam cov flange thiab lub vev xaib ua ke ntawm qhov txuas txuas txuas ntxiv. Rolled H-beam yog tsim nyob rau hauv niaj hnub steel dov ntau lawm siv universal dov mills, uas muaj peev xwm xyuas kom meej qhov tseeb dimension thiab kev ua tau zoo uniformity ntawm cov khoom.
H-beam yog dav siv nyob rau hauv ntau yam civil thiab industrial vaj tse, loj-span industrial nroj tsuag thiab niaj hnub high-sawv vaj tse, raws li zoo raws li cov choj loj, cov khoom hnyav, txoj kev loj, nkoj ntas, thiab lwm yam. cov nroj tsuag muaj nyob rau hauv cov cheeb tsam uas nquag seismic kev ua ub no thiab nyob rau hauv lub kub kub ua hauj lwm tej yam kev mob.
