ʻO ka ʻokoʻa ma waena o LVL, LVB, a me ka plywood

ʻOkoʻa ko lākou mau inoa, ʻokoʻa ke ʻano o ka papa, a ʻokoʻa ka ikaika compressive a me ka paʻa.
ʻO LVL, LVB, a me ka lāʻau pāpaʻi nā papa he nui, i hana ʻia e ke kāpili a me ke kaomi ʻana i nā ʻāpana he nui o ka veneer lāʻau.
E like me ka ʻaoʻao ākea a me ka pololei o ka hoʻonohonoho veneer lāʻau, hiki ke hoʻokaʻawale ʻia i LVL a me ka plywood.
ʻO ka Laminated Veneer Lumber, ʻike ʻia hoʻi ʻo LVL (Laminated Veneer Lumber), he ʻano o ka veneer i hana ʻia mai ka lāʻau maka ma o ka ʻoki ʻana a i ʻole ka hoʻolālā ʻana.Ma hope o ka maloʻo ʻana a me ka hoʻopili ʻana, ua ʻākoakoa ʻia ma ke ala o ka palaoa a laila kaomi wela a hoʻopili ʻia.Loaʻa iā ia nā hiʻohiʻona i loaʻa ʻole i ka lāʻau ʻili lāʻau paʻa: ikaika kiʻekiʻe, paʻa kiʻekiʻe, kūpaʻa maikaʻi, a me nā kikoʻī kikoʻī, ʻoi aku ka nui o ka ikaika a me ka paʻakikī ma mua o ka lāʻau ʻili lāʻau paʻa.Hiki ke hoʻohana ʻia kēia huahana no ke kūkulu ʻana i nā ʻāpana laʻa, nā kaola hale, nā panela kaʻa, nā lako, ka papahele, ka lumi hoʻonaninani lāʻau keel, a me nā mea hoʻopili, me ka nui o nā noi.

Hoʻohana maʻamau nā mea haʻahaʻa e hana i nā LVL Scaffolding Planks , LVL Formwork Beams, nā lako, nā pani puka puka, a me nā huahana huahana, ʻoiai nā mea kiʻekiʻe e hoʻohana ʻia e hana i nā kaola, nā kolamu, a me nā Structural LVL Beams no nā hale lāʻau.
Hoʻonohonoho ʻia ʻo LVL ma ka ʻaoʻao hoʻokahi, ʻoiai ua hoʻonohonoho ʻia ka plywood i hoʻokahi ʻaoʻao ākea a hoʻokahi ʻaoʻao kū.Loaʻa i nā ʻano papa ʻelua nā ʻano hana like ʻole a me nā ʻokoʻa hana, kēlā me kēia me kona manaʻo ponoʻī a paʻa paʻa, hiki ke nānā ʻia.

He ʻano hana ʻo LVB no ka hui ʻana i nā veneers plywood, a he ʻokoʻa hoʻi ka hoʻonohonoho ʻana o nā veneers lāʻau.Eia nō naʻe, ʻaʻole i māhele like ʻia ka helu o nā veneers lāʻau i hoʻonohonoho ʻia ma ke ākea a me ka longitudinally i kēlā me kēia manawa, i hoʻoholo ʻia e like me nā pono kikoʻī (e like me 3 horizontal, 2 vertical, a me 3 horizontal)
Inā ʻano lahilahi ka mānoanoa (maʻamau ma lalo o 25mm), a laila hoʻohana maʻamau ʻo LVB, no ka mea, hiki i ka hoʻohui ʻana i ka veneer transverse ke kāohi i ka deformation ākea o ka papa i kekahi ʻano.Inā he koi kiʻekiʻe no ka ikaika, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka hoʻolālā LVL.ʻElua mau ʻano o ka ikaika ma LVL: mua a me ka ʻaoʻao, a ʻelua mau ʻano o ka hoʻāʻo ikaika: static bending strength and elastic modulus

Hiki ke hoʻohālikelike ʻia kā lākou ʻokoʻa penei:
Hoʻohana: LVL veneer laminated lāʻau i hoʻohana nui ʻia i nā hale a me nā hale lāʻau;Hoʻohana nui ʻia ka Plywood no ka hoʻonaninani, nā lako, a me ka hoʻopili.ʻOiaʻiʻo, hana kekahi mau hale hana i ka LVL e like me ka poplar, hiki ke hoʻohana ʻia i loko o nā lako, nā mea hoʻonaninani, a me nā ʻeke.
Hana ʻia: LVL laminated veneer a me Plywood ua hana ʻia i ka veneer lāʻau ma o ke kaomi wela a me ka hoʻopaʻa ʻana, akā ʻokoʻa ke kuhikuhi o ka veneer.Hoʻonohonoho ʻia nā veneers LVL a pau ma ka ʻaoʻao hoʻokahi ma ka ʻaoʻao o ka palaoa, a ʻo ke ala o nā veneers lāʻau pili e pili like;Hoʻonohonoho ʻia ʻo Plywood ma ka ʻaoʻao a me ke ākea, me nā ʻāpana pili o nā veneers lāʻau e kū pono ana.
ʻAno: Ma kekahi ʻaoʻao, ʻokoʻa ke ʻano ke nānā ʻia mai kekahi ʻaoʻao, a ma ka ʻaoʻao ʻē aʻe, ʻo ka ʻili o ka Plywood a me lalo i hana ʻia me nā ʻili lāʻau lahilahi e like me Okoume, Bintangor, Red Oak, Ash, etc. nani loa a hoʻoikaika i ka hoʻonani;ʻO ka LVL laminated veneer, ma ke ʻano he hale a i ʻole nā ​​​​mea hana, e hoʻoikaika i ka ikaika a me ka deflection, akā ʻaʻohe koi kiʻekiʻe no nā panela.
Maikaʻi: LVL laminated veneer ua hana nui ʻia me ka lāʻau pine + phenolic resin (waterproof, formaldehyde release E0), aʻo Plywood ka mea maʻamau i hana ʻia me ka poplar/eucalyptus wood + MR glue (maʻamau ka moisture-proof, formaldehyde release E2, E1, E0).

ʻO ka ʻokoʻa nui ma waena o nā mea ʻelua aia i ka hoʻokumu ʻana, kaomi wela, a me ka hoʻoili ʻana o ka veneer.Mai ka hiʻohiʻona o nā ʻenehana hana, ʻoi aku ka paʻakikī o nā papa LVL i ka hana ʻana a me nā kaʻina hana, ʻoiai maʻalahi ka plywood.
ʻO ka ʻokoʻa o ka hana mua a me ka hana ʻana e hoʻoholo i ka pono huahana like ʻole ma waena o nā mea ʻelua.Ke hoʻohālikelike ʻia me ka plywood, ʻoi aku ka maikaʻi o ka papa LVL i ka ikaika, kūpaʻa, ka hana ʻana, ka hoʻopaʻa ʻana o ke ahi, ka hoʻokaʻawale leo, a me nā mea ʻē aʻe.
