Mapolanka a Laminated Veneer (LVL)ke lehong le entsoeng ka matla a phahameng le hlahisoang ka ho tlamahanya lera la li-multiple veneer veneers ka lera le sebelisang likhomaretsi.LVL e ile ea ntlafatsoa hore e sebelise mefuta e mecha le lifate tse nyenyane tse ke keng tsa sebelisoa ho etsa lehong le tiileng le sahiloeng.LVL ke thepa ea mohaho e theko e tlaase le e tsitsitseng e fanang ka matla a phahameng a sebopeho le ho tšepahala ha e sebelisoa lits'ebetsong tsa moralo.
Likarolo tsa Laminate Veneer Laminate (LVL).
LVL ke ea sehlopha sa Structural Composite Lumber (SCL) 'me e entsoe ka li-veneers tsa patsi tse omisitsoeng le tse hlophisitsoeng hantle.
Li-veneers li koahetsoe 'me li kopantsoe hammoho le sekhomaretsi se thibelang mongobo.Li-veneers li phuthetsoe ka tsela e le 'ngoe, ke hore, lijo-thollo tsa patsi li pota-potile bolelele ba letho (sekheo ke boto e feletseng eo ba kenngoa ho eona).
Veneer e sebelisetsoang ho etsa LVL e ka tlase ho 3 mm botenya mme e hlahisoa ka theknoloji ea spin-peeling.Li-veneers tsena li lokisitsoe hantle, li hlahlojoa hore ha ho na liphoso, li hlahlobjoa bakeng sa boemo ba mongobo 'me li khaola ka ho sebelisa li-rotary shears ho bophara bo lekanang le 1.4 m bakeng sa tlhahiso ea LVL.
LVL e kotsing ea ho bola ha e pepesehetse mongobo o mongata kapa e sebelisoa libakeng tse se nang moea.Ka hona, LVL e lokela ho alafshoa ka sebatli ho thibela ho bola kapa ho tšoaetsoa ha lits'ebetso tse joalo.
LVL e ka sehoa, ea khokhotheloa le ho phunngoa ka lisebelisoa tse tloaelehileng.Likoti li ka boela tsa phunyeletsoa ho litho tsena bakeng sa litšebeletso tsa ho kenya.
Lipampiri tsa LVL kapa likheo li entsoe ka botenya ho tloha ho 35 ho isa ho 63 mm le bolelele ho fihlela ho 12 m.
Ho hanyetsa mollo oa LVL ho tšoana le patsi e tiileng 'me ho chesoa ho lieha ebile ho ka lebelloa.Litefiso lia fapana ho latela mofuta oa patsi e sebelisoang le boholo ba litho.
Kaha li-veneers tsa LVL li lebisitsoe nqa e le 'ngoe, li loketse ka ho khetheha bakeng sa kaho ea maballo.Mabala a LVL a na le bolelele, botebo le matla a ho jara meroalo hantle ka nako e telele.
Melemo ea LVL
LVL e na le karo-karolelano e babatsehang ea matla le boima ba 'mele, ke hore, LVL e nang le litekanyo tse nyenyane e na le matla a maholo ho feta thepa e tiileng.E boetse e matla ho feta boima ba eona.
Ke thepa e matla ka ho fetisisa ea lehong e amanang le ho teteana ha eona.
LVL ke sehlahisoa sa lehong se nang le mekhoa e mengata.E ka sebelisoa ka plywood, lehong kapa oriented strand board (OSB).
Ho itšetlehile ka moetsi, LVL e ka etsoa ka maqephe kapa li-billet tsa boholo leha e le bofe kapa boholo.
LVL e entsoe ka thepa ea lehong ea boleng bo tšoanang le bofokoli bo fokolang.Ka hona, thepa ea bona ea mechine e ka boleloa esale pele habonolo.
LVL e ka etsoa ho latela litlhoko tsa sebopeho.
Tšebeliso ea LVL ho Architecture
LVL e ka sebelisoa ho etsa maballo a I, maballo, litšiea, linte, matšoao a litsela, lihlooho, liphanele tsa rim, formwork, litšehetso tsa fatše le tse ling.Ha ho bapisoa le lehong le tiileng, matla a phahameng a LVL a etsang hore e be khetho e tloaelehileng bakeng sa ho haha li-trusses, purlins, truss chords, rafters, le tse ling.
LVL e hloka tlhokomelo e nepahetseng le litlhoko tsa polokelo ho qoba mathata a ntoa.Leha LVL e theko e tlase ho e hlahisa, e hloka matsete a holimo a mantlha.
