Feem ntau tuab ntawm LVL yog 45 hli (1-3/4 nyob rau hauv), los ntawm uas dav kab teeb yuav yooj yim tsim los ntawm fastening ntau yam LVL plies ua ke ntawm qhov chaw. LVL kuj tuaj yeem tsim nyob rau hauv tuab los ntawm 19 mm (3/4 nyob rau hauv) mus rau 178 mm (7 nyob rau hauv).

Ib sab ntawm no, puas yog LVL muaj zog dua li cov ntoo ntoo?

LVL muaj ntau qhov zoo dua li cov milled ntoo : Ua nyob rau hauv ib lub Hoobkas raws li kev tswj specifications, nws yog muaj zog dua , straighter, thiab ntau uniform. Vim nws qhov sib xyaw ua ke, nws muaj peev xwm tsawg dua tshaj ib txwm ntoo rau warp, twist, hneev, los yog shrink.

Ib sab saum toj no, qhov loj npaum li cas yog DO qib? Qhov ntau thiab tsawg yuav txawv raws li cov chaw tsim khoom tab sis Georgia Pacific hais tias LVL tus qauv thicknesses yog 1 3/4 ntiv tes thiab 3 1/2 ntiv tes. Ntev yog feem ntau muaj nyob rau hauv 24, 28, 32, 36, 40 thiab 44 ko taw nrog kev txiav txim tshwj xeeb txog li 60 ko taw.

Tsis tas li ntawd paub, yuav ua li cas cov theem beam loj npaum li cas xam?

1. Ntsuas koj qhov kev ncua sij hawm tag nrho ntawm cov tswv cuab thiab xyuas kom meej tias nws tsis siab tshaj 60 ko taw.
2. Tsim ib kab dav raws li qhov tseeb tias qhov dav dav ntawm LVL nqaj yog 1 3/4 ntiv tes.
3. Tsim ib tug beam qhov tob raws li txoj cai ntawm tus ntiv tes xoo rau kwv yees qhov tob ntawm cov kab hluav taws xob tsim uas yog faib qhov ncua sij hawm los ntawm 20.

Ntev npaum li cas koj tuaj yeem ncav cuag 2x12 LVL?

Thaum txhawb joists tias ncua 12 ko taw uas tsis muaj overhang dhau ntawm kab teeb, ob chav ply beam tau span hauv taw tus nqi sib npaug rau nws qhov tob hauv ntiv tes. Ib ob 2 x12 nqaj tau span 12 ko taw; ib (2) x 10 tau span 10 feet thiab lwm yam.
