W beams, yog cov ntsiab lus tseem ceeb hauv kev tsim kho thiab kev tsim kho, ua tsaug rau lawv lub zog thiab kev hloov pauv tau yooj yim. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov qhov ntev sib xws, cov ntaub ntawv siv, thiab cov yuam sij rau kev xaiv W beam kom raug rau koj qhov project, suav nrog xws liLub teeb 14x22 W, Lub teeb 16x26 W, ASTM A992 W beam, thiab ntau ntxiv.
AW beam yog ib daim hlau profile uas muaj ib daim duab "W", uas muaj ib lub ncej (seem ntsug nruab nrab) thiab ob lub flanges (seem kab rov tav ntawm ob sab). Cov geometry no muab kev tiv thaiv zoo heev rau kev khoov thiab kev thauj khoom, ua rau lawv zoo tagnrho rau kev txhawb nqa cov qauv hauv cov tsev, choj, thiab cov haujlwm kev lag luam. Cov lus W-beam, W-profile, thiab W-beam feem ntau siv hloov pauv los xa mus rau hom profile no.
Qhov ntev ntawm W-beam yog txhais los ntawm lawv qhov siab tag nrho (ntsuas los ntawm ib kawg ntawm lub flange mus rau lwm qhov) thiab qhov hnyav ib ko taw linear, txawm hais tias lawv qee zaum raug xa mus rau qhov siab thiab dav ntawm flange hauv luv luv. Qee qhov ntev nrov dua suav nrog:
12x16 W Beam: Kwv yees li ntawm 12 nti siab, hnyav 16 phaus ib ko taw.
6x12 W Beam: siab 6 nti, hnyav 12 phaus ib ko taw, zoo tagnrho rau cov ntawv thov me dua.
14x22 W Beam: siab 14 nti, hnyav 22 phaus ib ko taw, siv rau hauv cov qauv nruab nrab.
16x26 W BeamNws siab 16 ntiv tes thiab hnyav 26 phaus ib ko taw, nws tsim nyog rau cov khoom hnyav dua.
Cov hlau W-beam feem ntau siv ua tau raws li tus qauv ASTM A992, uas txhais cov hlau ua tau zoo nrog lub zog tso zis ntawm 50 ksi (50,000 phaus ib square inch). Cov hlau no paub txog:
Nws txoj kev tiv thaiv corrosion thaum kho nrog kev kho mob tiv thaiv.
Nws qhov ductility, uas tso cai rau kev tswj hwm deformations yam tsis muaj kev tawg.
Nws muaj peev xwm tiv taus cov khoom thauj static thiab dynamic, ua rau nws zoo tagnrho rau cov chaw ib puag ncig hnyav.
Ntxiv rauASTM A992 hlau, W-beams kuj tseem tuaj yeem pom muaj nyob rau hauv lwm hom hlau, xws li ASTM A36, txawm hais tias A992 yog qhov nyiam dua hauv cov haujlwm loj vim nws lub zog ntau dua.
Txhais cov Kev Cai Txuj Ci
Cov Khoom Txhawb Nqa: Xam cov khoom thauj uas tsis hloov pauv (qhov hnyav ntawm tus kheej) thiab cov khoom thauj uas hloov pauv tau (cov khoom thauj uas txav mus los) uas lub nqaj yuav txhawb nqa. Cov qauv xws li 16x26 W-beam yog qhov tsim nyog rau cov khoom thauj hnyav, thaum 6x12 W-beam zoo dua rau cov qauv me me.
Qhov Ntev Yuav Tsum Tau Ua: Cov W-beams yog tsim los ntawm cov qhov ntev ib txwm muaj, tab sis tuaj yeem hloov kho rau txhua qhov project. Xyuas kom tseeb tias qhov ntev yuav tsis ua rau muaj teeb meem kev thauj mus los lossis kev teeb tsa.
Xyuas kom meej tus qauv thiab cov khoom siv
Xyuas kom tseeb tias lub nqaj ua tau raws li tus qauv ASTM A992 yog tias nws yog ib qho project loj, vim qhov no lav cov khoom siv kho tshuab sib xws.
Tshawb xyuas qhov zoo ntawm cov hlau: nws yuav tsum muaj cov cim qhia thiab daim ntawv pov thawj ntawm kev ua raws li cov qauv thoob ntiaj teb.
Tshuaj xyuas tus neeg muab khoom
Nyiam cov chaw tsim khoom uas muaj kev paub txog hlauW-beamsthiab lub koob npe nrov hauv kev ua lag luam. Saib cov ntaub ntawv qhia thiab tshuaj xyuas lawv cov haujlwm yav dhau los.
Muab cov nqi sib piv, tab sis tsis txhob hnov qab tias qhov zoo ntawm cov khoom siv tseem ceeb dua li tus nqi qis. Cov W-beams tsis zoo tuaj yeem ua rau cov qauv tsis ua haujlwm ntev.
Xav txog kev kho qhov chaw
Cov kab W uas raug rau ib puag ncig yuav tsum muaj kev kho mob tiv thaiv xeb, xws li xim epoxy lossis galvanization. Qhov no ua rau lawv ruaj khov dua, tshwj xeeb tshaj yog nyob rau hauv thaj chaw uas muaj av noo lossis ntsev.
Txheeb xyuas daim ntawv thov tshwj xeeb
Rau cov haujlwm xws li cov choj lossis cov tsev siab, kev xaiv W-beam yuav tsum tau ua ua ke nrog tus kws tsim qauv, uas yuav txiav txim siab qhov loj me thiab cov ntaub ntawv tsim nyog raws li cov qauv hauv zos thiab cov kev xav tau thauj khoom.
Cov W-beams yog cov khoom tseem ceeb hauv kev tsim kho niaj hnub no, thiab lawv qhov kev xaiv kom raug yog nyob ntawm kev nkag siab txog lawv qhov loj me (xws li 14x22 W-beam lossis 12x16 W-beam), cov khoom siv (tshwj xeeb tshaj yog ASTM A992 hlau), thiab cov kev cai ntawm qhov project. Thaum yuav khoom, qhov tseem ceeb tshaj plaws yog qhov zoo, kev ua raws li cov qauv, thiab lub koob npe nrov ntawm tus neeg muag khoom, yog li ua kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm koj cov qauv.
