I-beams

Kuv - Beams tau siv dav hauv cov tuam tsev thiab lwm cov qauv hlau. Seb kuv - ci lossis lub teeb I- Beams (xws li} kab hlau), lawv qhov siab} kev siab yog feem ntau100-900 hli, thiab ntu dav yog hais txog50-300 hli.

Lub sij hawm ntawm inertia ntawm ntu raws ob lub ntsiab axes tuaj yeem ncav cuag10,000-10⁷m, yog li lawv feem ntau yog siv ncaj qha raws li web - dav hlau khoov cov tswv cuab hauv cov tswv cuab hauv cov qauv hauv siab.

Hauv kev tsim qauv txheej txheem, kev xaiv ntawm i {- cov kab teeb yuav tsum yog raws lawv cov khoom ntiag tug (tawm lub zog235-355 MPa, tensile lub zog370-510 MPA), Tshuaj lom neeg cov khoom (cov ntsiab lus carbonTsawg dua los yog sib npaug rau 0.22%), Weldability, txheej txheem qhov loj me, thiab lwm yam kom tsim nyog qhov tsim nyog kuv {{nqaj tsim nyog.

Qhov zoo ntawm kuv - ci

Tsim qauv tsim:Kuv {- ci ci muaj cov txiaj ntsig zoo, ua kom txiav, khoov, thiab vuam yooj yim. Lawv tsim kev tsim kom haum kuj ua kom muaj kev kho kom haum raws li qhov ua tau. Piv txwv li, txoj kev khoov vojvoog tau txog1.5-2 lub sij hawm ntawm ntu qhov siab, thiab qhov ntsuas kub yog650-750 degree.

Muaj zog durability:Kuv {- ci ci ua tau zoo ua kom cov laus tiv taus thiab lub neej ntev ntawm50 xyooCov. Lawv cov kev cuam tshuam lub zog tuaj yeem ncav cuag120-200 j / cm², thiab lawv cov coj tsis kam tshaj lwm tus hlau tsim muaj ntau yam kev tsim kho, ua kom muaj kev ruaj khov thiab lub sijhawm siv sijhawm thaum siv.

Lub teeb hnyav:Qhov hnyav ntawm kuv {- Beams muaj ntau dua los ntawm10-200 kg / mNyob ntawm seem. Cov txheej txheem kev tsim kho yog yooj yim thiab nrawm, txuagTxog 20-30%ntawm lub sijhawm tsim kho thiab txhim kho kev txhim kho phiaj xwm ua tau zoo.

Khoom zoo lub cev:Kuv {- Beams tseem muaj rwb thaiv tsev zoo, sib nqus permeability (0.001–0.01 H/m), thiab kev tiv thaiv hluav taws kub heev (kev ntaus hluav taws kubA1) thiab cov cua sov rwb thaiv tsev.

Cov teeb meem txheej txheej txheej txheej:Lub galvanizing txheej, feem ntau50–100 μmtuab, yog Metallurgically sib khi rau tus hlau, muab kev tiv thaiv ruaj khov thiab txhim khu kev qha. Galvanization tuaj yeem npog txhua feem ntawm cov khoom siv, suav nrog recesses, fab, thiab cov chaw zais.
