Feem ntau ntev spans ua rau hloov tau yooj yim, kab-dawb sab hauv qhov chaw, txo cov nqi tsim khoom, thiab txo cov sij hawm erection steel.

Thiab cov lus nug yog, ntev npaum li cas steel beam span?

Yog lawm. Koj tau tau siab txaus steel kuv - nqaj tias yuav span 25 ko taw tsis muaj kab.

Qhov thib ob, qhov ntev ntawm lub nqaj yog dab tsi? Nws yog qhov nyuaj, tab sis cov cai ntiv tes xoo tuaj yeem ua haujlwm yog tias cov qauv yooj yim. Nws yog ib txwm pom zoo kom siv cov qauv tsim software xws li ETabs lossis Staad pro rau kev tsim. Hauv a nqaj txog li 5 meters ntev , theem nrab spans txog li 4 meters, phab ntsa loads txog li 8 kN ib tug khiav 'meter', Kuv siv tau cov hlau raws li hauv qab no.

Ib yam li ntawd, kuv tuaj yeem ncav cuag qhov ntev npaum li cas?

Thaum txhawb joists tias ncua 12 ko taw tsis muaj overhang tshaj qhov nqaj , ib ob ply beam tau span hauv taw tus nqi sib npaug rau nws qhov tob hauv ntiv tes. Ib ob 2 x 12 beam tau span 12 ko taw; ib (2) x 10 tuaj yeem ncua 10 ko taw thiab lwm yam.

Kuv xav tau 20 feet ntev npaum li cas?

Re: 20 ko taw clearspan nqaj size Qhov ntawd, koj xav tau ib yam dab tsi zoo li 12-16 "GLULAM lossis LVL rau ncua tus 20 ' thiab siv tau yooj yim 2x8-10 qhov ntev lumber 16 "OC li hauv pem teb joists.
