Lumber Laminated Veneer (LVL)ndi matabwa amphamvu kwambiri omwe amapangidwa pomangirira ma veneer angapo wosanjikiza pogwiritsa ntchito zomatira.LVL inapangidwa kuti igwiritse ntchito zamoyo zatsopano ndi mitengo ing'onoing'ono yomwe singagwiritsidwe ntchito popanga matabwa odulidwa.LVL ndi zomangira zotsika mtengo komanso zokhazikika zomwe zimapereka mphamvu zamapangidwe apamwamba komanso zodalirika zikagwiritsidwa ntchito pamapangidwe.
Mawonekedwe a Laminate Veneer Laminate (LVL)
LVL ndi ya gulu la Structural Composite Lumber (SCL) ndipo imapangidwa kuchokera ku matabwa owuma komanso opangidwa ndi matabwa, mizere kapena mapepala.
Ma veneers amakutidwa ndikumangika pamodzi ndi zomatira zosagwira chinyezi.Ma veneers amatsatiridwa mbali imodzi, mwachitsanzo, njere yamatabwayo imakhala yofanana ndi kutalika kwa chopanda kanthu (chopanda kanthu ndi bolodi lathunthu lomwe amalowetsamo).
Veneer yomwe imagwiritsidwa ntchito popanga LVL imakhala yocheperapo 3 mm ndipo imapangidwa pogwiritsa ntchito ukadaulo wa spin-peeling.Ma veneerswa amakonzedwa bwino, amafufuzidwa ngati ali ndi zolakwika, amawunikidwa kuti apeze chinyezi ndikudula pogwiritsa ntchito shear yozungulira mpaka m'lifupi mwake wofanana ndi 1.4 m popanga LVL.
LVL imayamba kuvunda ikakhala ndi chinyezi chambiri kapena ikagwiritsidwa ntchito m'malo opanda mpweya.Chifukwa chake, LVL iyenera kuthandizidwa ndi mankhwala oteteza kuti asawole kapena kufalikira pazogwiritsa ntchito ngati izi.
LVL imatha kuchekedwa, kukhomeredwa ndi kubowola ndi zida wamba.Mabowo amathanso kukhomeredwa mwa mamembalawa kuti azithandizira.
Mapepala a LVL kapena opanda kanthu amapangidwa mu makulidwe kuchokera 35 mpaka 63 mm ndi kutalika mpaka 12 m.
Kukaniza kwa moto kwa LVL ndikofanana ndi nkhuni zolimba ndipo kuwotcha kumakhala kochedwa komanso kodziwikiratu.Mitengo imasiyanasiyana malinga ndi mtundu wa nkhuni zomwe zimagwiritsidwa ntchito komanso kukula kwa mamembala.
Popeza ma veneers mu LVL amalunjika mbali imodzi, ndi oyenera kupanga matabwa.Miyendo ya LVL imakhala ndi kutalika, kuya ndi mphamvu zonyamula katundu pazitali zazitali.
Ubwino wa LVL
LVL ili ndi mphamvu zowoneka bwino komanso mphamvu zolemera, ndiye kuti, LVL yokhala ndi miyeso yaying'ono imakhala ndi mphamvu zambiri kuposa zinthu zolimba.Ndilonso lamphamvu poyerekezera ndi kulemera kwake.
Ndilo matabwa amphamvu kwambiri poyerekezera ndi kachulukidwe kake.
LVL ndi chinthu chamatabwa chosunthika.Itha kugwiritsidwa ntchito ndi plywood, matabwa kapena oriented strand board (OSB).
Kutengera wopanga, LVL imatha kupangidwa m'mapepala kapena ma billets amtundu uliwonse kapena kukula kwake.
LVL imapangidwa kuchokera kumitengo yamitengo yofananira komanso zolakwika zochepa.Choncho, mawotchi awo amatha kuneneratu mosavuta.
LVL ikhoza kupangidwa mwamakonda malinga ndi zofunikira.
Kugwiritsa ntchito LVL mu Architecture
LVL ingagwiritsidwe ntchito kupanga matabwa a I-, mizati, mizati, lintels, zolembera zamsewu, mitu, mapanelo amphepete, mawonekedwe, zothandizira pansi ndi zina.Poyerekeza ndi matabwa olimba, kulimba kwamphamvu kwa LVL kumapangitsa kukhala chisankho chodziwika bwino popanga ma trusses, purlins, truss chords, rafters, ndi zina zambiri.
LVL imafuna kusamalira bwino ndi kusungirako zofunikira kuti mupewe zovuta.Ngakhale LVL ndiyotsika mtengo kupanga, imafunikira ndalama zambiri zoyambira.
