Laminated Veneer Lumber (LVL)yog ib tug high-strength engineered ntoo tsim los ntawm kev sib txuas ntau veneer veneers txheej los ntawm txheej siv cov nplaum.LVL tau tsim los siv hom tshiab thiab cov ntoo me uas tsis tuaj yeem siv los ua cov ntoo saws.LVL yog cov khoom siv hluav taws xob zoo thiab muaj txiaj ntsig zoo uas muab cov qauv tsim muaj zog thiab kev ntseeg siab thaum siv hauv cov qauv siv.
Laminate Veneer Laminate (LVL) nta
LVL belongs rau Cov Qauv Txheej Txheem Lumber (SCL) qeb thiab yog tsim los ntawm cov ntoo qhuav thiab qib veneers, strips lossis nplooj ntawv.
Cov veneers yog txheej thiab sib koom ua ke nrog cov nplaum nplaum uas tiv taus dej.Cov veneers yog stacked nyob rau hauv tib txoj kev, piv txwv li cov grain ntawm cov ntoo yog perpendicular mus rau qhov ntev ntawm lub dawb paug (ib qho dawb paug yog tag nrho cov board lawv stacked rau hauv).
Cov veneer siv los ua LVL yog tsawg dua 3 hli tuab thiab tsim los ntawm kev siv tshuab spin-peeling.Cov veneers no tau npaj zoo, tshuaj xyuas qhov tsis xws luag, txheeb xyuas cov ntsiab lus ntawm cov dej noo thiab txiav siv cov rotary shear rau qhov dav sib npaug li 1.4 m rau LVL ntau lawm.
LVL tuaj yeem raug rotting thaum raug cov dej noo siab lossis siv hauv qhov chaw tsis muaj cua.Yog li, LVL yuav tsum tau kho nrog cov tshuaj tiv thaiv kom tsis txhob lwj lossis kab mob hauv cov ntawv thov.
LVL tuaj yeem saws, nailed thiab drilled nrog cov cuab yeej siv.Lub qhov tseem tuaj yeem raug punched hauv cov tswv cuab rau kev pabcuam kev teeb tsa.
LVL nplooj ntawv los yog qhov khoob yog tsim nyob rau hauv thicknesses ntawm 35 mus rau 63 hli thiab nyob rau hauv ntev mus txog 12 m.
LVL hluav taws kuj zoo ib yam li cov ntoo thiab charring yog qeeb thiab kwv yees.Cov nqi sib txawv nyob ntawm seb hom ntoo siv thiab qhov loj ntawm cov tswv cuab.
Txij li cov veneers nyob rau hauv LVL yog taw qhia nyob rau hauv tib txoj kev, lawv yog tshwj xeeb tshaj yog haum rau beam tsim.LVL kab teeb muaj qhov ntev, qhov tob thiab lub zog kom ua tau zoo nqa cov khoom ntev ntev.
Qhov zoo ntawm LVL
LVL muaj qhov zoo ntawm qhov loj me thiab qhov hnyav-lub zog piv, uas yog, LVL nrog qhov me me muaj lub zog ntau dua li cov khoom siv.Nws kuj muaj zog dua piv rau nws qhov hnyav.
Nws yog cov khoom siv ntoo uas muaj zog tshaj plaws rau nws qhov ntom.
LVL yog cov khoom siv ntoo ntau yam.Nws tuaj yeem siv nrog plywood, ntoo lossis oriented strand board (OSB).
Nyob ntawm cov chaw tsim khoom, LVL tuaj yeem tsim nyob rau hauv cov ntawv lossis cov ntawv loj ntawm txhua qhov loj lossis qhov ntev.
LVL yog tsim los ntawm cov khoom siv ntoo ntawm cov khoom zoo thiab qhov tsis xws luag.Yog li ntawd, lawv cov khoom siv kho tshuab tuaj yeem kwv yees tau yooj yim.
LVL tuaj yeem tsim kho raws li cov qauv tsim.
Kev siv LVL hauv Architecture
LVL tuaj yeem siv los tsim I-nqaj, kab teeb, kab, kab, kab ntawv, txoj kev cim, headers, rim panels, formwork, pem teb kev txhawb nqa thiab ntau dua.Piv nrog rau cov khoom ntoo, LVL lub zog tensile siab ua rau nws yog ib qho kev xaiv rau kev tsim trusses, purlins, truss chords, pitched rafters, thiab ntau dua.
LVL yuav tsum tau tuav kom zoo thiab khaws cia kom tsis txhob muaj teeb meem warping.Txawm hais tias LVL pheej yig los tsim, nws xav tau kev nqis peev thawj zaug.
