Xov Xwm - Ua tiav Phau Ntawv Qhia rau W Beams: Dimensions, Materials, and Purchasing Considerations

W beam, yog cov txheej txheem tseem ceeb hauv engineering thiab kev tsim kho, ua tsaug rau lawv lub zog thiab ntau yam. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov dav dav, cov ntaub ntawv siv, thiab cov yuam sij los xaiv txoj cai W beam rau koj qhov project, suav nrog xws li14 x 22 W, 16 x 26 W, ASTM A992 W beam, thiab ntau dua.

Qhov tob tob rau hauv H-Beams tsom rau ASTM A992

W beam yog dab tsi?

AW beam yog hlau profile nrog "W"-zoo li tus ntoo khaub lig-section, muaj xws li ib tug ncej (nruab nrab seem) thiab ob flanges (kab rov tav seem ntawm ob sab). Qhov geometry no muab kev tiv thaiv zoo heev rau kev khoov thiab thauj khoom, ua rau lawv zoo tagnrho rau kev txhawb nqa hauv cov tsev, txuas hniav, thiab cov haujlwm ua haujlwm. Cov ntsiab lus W-beam, W-profile, thiab W-beam feem ntau siv sib hloov los xa mus rau hom profile no.

Common W-Beam Dimensions

W-beam qhov ntev yog txhais los ntawm lawv qhov siab tag nrho ( ntsuas los ntawm ib qho kawg ntawm flange mus rau lwm qhov) thiab qhov hnyav ntawm ib qho taw qhia, txawm hais tias lawv qee zaum hu ua flange qhov siab thiab dav hauv shorthand. Qee qhov nrov tshaj plaws muaj xws li:
12 x 16 W: Kwv yees li 12 ntiv tes siab, hnyav 16 phaus ib ko taw.
6 x 12 W: 6 nti siab, hnyav 12 phaus ib ko taw, zoo tagnrho rau kev siv me me.
14 x 22 W: 14 nti siab, hnyav 22 phaus ib ko taw, siv hauv cov qauv nruab nrab.
16 x 26 W: Ntawm 16 ntiv tes siab thiab hnyav 26 phaus ib ko taw, nws tsim nyog rau cov khoom hnyav dua.

Feem ntau siv W-beam steel ua tau raws li ASTM A992 tus qauv, uas txhais tau hais tias cov hlau ua tau zoo nrog lub zog ntawm 50 ksi (50,000 phaus ib square inch). Cov hlau no muaj npe rau:
Nws tiv thaiv corrosion thaum kho nrog kev tiv thaiv kev kho mob.
Nws ductility, uas tso cai rau tswj deformations yam tsis muaj kev tawg.
Nws muaj peev xwm tiv taus static thiab dynamic loads, ua rau nws zoo tagnrho rau ib puag ncig hnyav.
Ntxiv rauASTM A992 hlau, W-beams kuj tuaj yeem pom nyob rau hauv lwm hom hlau, xws li ASTM A36, txawm hais tias A992 nyiam nyob rau hauv cov haujlwm loj vim nws lub zog ntau dua.

Kev txiav txim siab tseem ceeb thaum yuav W-Beams

Txhais cov kev xav tau
Txhawb nqa Loads: xam qhov zoo li qub (tus kheej qhov hnyav) thiab dynamic (tsav loads) loads lub nqaj yuav txhawb nqa. Cov qauv xws li 16x26 W-beam yog tsim rau cov khoom hnyav, thaum lub 6x12 W-beam zoo dua rau cov qauv me.
Yuav Tsum Tau Ntev: W-beams yog tsim nyob rau hauv tus qauv ntev, tab sis tuaj yeem hloov kho rau txhua qhov project. Xyuas kom tseeb tias qhov ntev yuav tsis ua rau kev thauj mus los lossis teeb meem kev teeb tsa.

Txheeb xyuas tus qauv thiab cov khoom siv
Xyuas kom cov nqaj ua tau raws li ASTM A992 tus qauv yog tias nws yog ib qhov haujlwm tseem ceeb, vim qhov no tau lees paub cov khoom siv tshuab tsis sib xws.
Tshawb xyuas cov hlau zoo: nws yuav tsum tso saib cov chaw tsim khoom kos npe thiab daim ntawv pov thawj ntawm kev ua raws li cov qauv thoob ntiaj teb.

Ntsuas tus neeg muab khoom
Txaus siab rau cov tuam ntxhab nrog kev paub hauv steelW-beamsthiab lub koob npe nrov hauv kev ua lag luam. Tshawb xyuas cov ntaub ntawv thiab tshuaj xyuas lawv cov haujlwm yav dhau los.

Sib piv cov nqi, tab sis tsis txhob hnov qab tias cov khoom zoo yog qhov tseem ceeb tshaj tus nqi qis. W-beams tsis zoo tuaj yeem ua rau kev ua haujlwm tsis zoo nyob rau lub sijhawm ntev.

Xav txog kev kho deg
W-beams raug rau ib puag ncig yuav tsum muaj kev tiv thaiv corrosion, xws li epoxy xim lossis galvanization. Qhov no ua rau lawv cov kav ntev, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj av noo los yog salinity.

Txheeb xyuas cov ntawv thov tshwj xeeb
Rau cov haujlwm xws li txuas hniav lossis cov tsev siab, kev xaiv ntawm W-beam yuav tsum tau ua nrog rau tus kws tsim qauv, uas yuav txiav txim siab qhov tsim nyog thiab cov khoom siv raws li cov qauv hauv zos thiab cov kev xav tau ntawm kev thauj khoom.

W-beams yog cov khoom tseem ceeb hauv kev tsim kho niaj hnub no, thiab lawv cov kev xaiv raug yog nyob ntawm kev nkag siab lawv qhov ntev (xws li 14x22 W-beam lossis 12x16 W-beam), cov khoom siv (tshwj xeeb tshaj yog ASTM A992 steel), thiab qhov project yuav tsum. Thaum yuav khoom, ua qhov tseem ceeb ntawm qhov zoo, ua raws li cov qauv, thiab tus neeg muag khoom lub koob npe nrov, yog li ua kom muaj kev nyab xeeb thiab kav ntev ntawm koj cov qauv.
