E eseese o latou igoa, e ese foi le fausaga o le laupapa, ma e ese le malosi o le compressive ma le mausali.
O le LVL, LVB, ma le plywood o laupapa e tele fa'apipi'i, e fai i le kelu ma le oomiina o le tele o laulau o fafie fafie.
E tusa ai ma faʻataʻitaʻiga faʻalava ma faʻasaga i luga o le faʻatulagaga faʻapipiʻi laupapa, e mafai ona vaevaeina i le LVL ma le plywood.
Laminated Veneer Lumber, lea e ta'ua o le LVL (Laminated Veneer Lumber), o se ituaiga o veneer e faia mai fafie mata e ala i le tipi fa'ata'amilo po'o le fuafuaina.A maeʻa ona faʻamago ma faʻapipiʻi, ona faʻapipiʻi lea i le itu o le saito ona faʻapipiʻi vevela ma faʻapipiʻi.O lo'o i ai uiga fa'atulagaina e le o iai i le fa'alava laupapa: malosi maualuga, malosi maualuga, mautu lelei, ma fa'amatalaga sa'o, lea e faatoluina le maualuga o le malosi ma le ma'a'a'a nai lo fafie.O lenei oloa e mafai ona faʻaaogaina mo le fausiaina o vaega faʻataʻitaʻiga, fale faʻalava, faʻataʻavalevale taavale, meaafale, fola, teuteuga o potu kiel laupapa, ma mea afifiina, ma le tele o faʻaoga.
O mea maualalo e masani ona faʻaaogaina e fai ai LVL Scaffolding Planks , LVL Formwork Beams, meaafale, faitotoʻa pito i luga, ma faʻapipiʻi oloa, ae o mea maualuga e faʻaaogaina e fai ai faʻalava, koluma, ma Structural LVL Beams mo fausaga laupapa.
LVL e fa'atulagaina uma i le itu e tasi, a'o plywood e fa'atulaga i le tasi fa'ata'atia ma le tasi itu tu'usa'o.O ituaiga e lua o laupapa e eseese fausaga ma faʻatinoga faʻatinoga, e taʻitasi ma lona lava taulaʻi ma le mautu malosi, lea e mafai ona siaki.
LVB o se metotia o le faʻapipiʻiina o plywood veneers, e iai foʻi se eseʻesega o faʻapipiʻi laupapa.Peitaʻi, o le aofaʻi o veneers laupapa e faʻatulagaina faʻalava ma umi i taimi taʻitasi e le tutusa le tufatufaina, lea e fuafuaina e tusa ai ma manaʻoga faʻapitoa (e pei o le 3 faalava, 2 tūsaʻo, ma le 3 faʻalava)
Afai o le mafiafia e fai si manifinifi (masani i lalo ifo o le 25mm), ona faʻaaogaina lea o le LVB, aua o le faʻapipiʻiina o veneer transverse e mafai ona pulea le lautele o le faʻaogaina o le laupapa i se tulaga patino.Afai ei ai se manaʻoga maualuga mo le malosi, e sili ona lelei le faʻaogaina o le fausaga LVL.E masani ona lua ituaiga o malosi i luga o le LVL: luma ma le itu, ma e masani lava e lua ituaiga o suʻega malosi: malosi faʻapipiʻi malosi ma faʻapipiʻi modulus.
O lo latou eseesega e masani lava e mafai ona faʻamaonia e pei ona taua i lalo:
Fa'aoga: LVL veneer laminated laupapa e masani ona fa'aogaina i fale ma fausaga laupapa;Plywood e masani ona faʻaaogaina mo teuteuga, meafale, ma afifiina.O le mea moni, o nisi fale gaosi oloa e gaosia LVL e pei o poplar, lea e mafai foi ona faʻaaogaina i meaafale, teuteuga, ma afifiina.
Fauga: LVL laminated veneer ma Plywood e faia uma i laupapa veneer e ala i vevela oomi ma fusi, ae o le faatulagaga o le itu o le veneer e ese.O LVL veneers uma o loʻo faʻatulagaina i le itu lava e tasi i luga o le saito, ma o le itu o vaʻa faʻapipiʻi laupapa e tutusa;O plywood o lo'o fa'atulaga i luga ma fa'alava, fa'atasi ai ma fa'apa'aga o fafie e fa'atatau i luga.
Faʻaaliga: I le tasi itu, o le fausaga e ese pe a vaʻaia mai le tasi itu, ma i le isi itu, o le Plywood luga ma lalo e masani lava ona faia i paʻu laupapa manifinifi e pei o Okoume, Bintangor, Red Oak, Ash, ma isi, o loʻo i ai. matagofie tele ma faʻamamafa teuteuga;LVL laminated veneer, e pei o se fale poʻo se mea faʻapipiʻi, faʻamalosia le malosi ma le faʻafefe, ae leai ni manaʻoga maualuga mo panels.
Mea: LVL laminated veneer e masani lava ona faia i laupapa paina + phenolic resin (waterproof, formaldehyde tatala E0), ao Plywood e masani ona faia i poplar / eucalyptus laupapa + MR kelu (masani susu-faamaonia, formaldehyde tatala E2, E1, E0).
O le eseesega tele i le va o ia mea e lua o loʻo taoto i le faʻatulagaina, vevela vevela, ma le faʻatulagaina o le veneer.Mai le va'aiga o metotia gaosiga, o laupapa LVL e sili atu ona lavelave i le gaosiga ma le fa'agasologa o faiga, ae o plywood e faigofie lava.
O le ese'esega i le mua'i fa'agaioiina ma le gaosiga e iloa ai le 'ese'ese o le aoga o oloa i le va o le lua.Pe a faatusatusa i plywood, LVL laupapa e sili atu ona lelei i le malosi, mautu, faagasologa, mumu mumu, leo insulation, ma isi itu.
