LVL Formwork Beam
Hōʻike huahana
ʻO ka lāʻau Pine LVL piha, ka hana LVL, nā lāʻau LVL a i ʻole ka lāʻau Strand/Laau i hana ʻia/Laau lāʻau o ka lāʻau ʻenekinia no ka hoʻoheheʻe ʻana iā LVL Structural LVL
HW structural laminated veneer lumber (LVL) i hana ʻia e like me AS/NZS 4357 me nā waiwai i hoʻoholo ʻia e like me AS/NZS 4063.2 a no laila e hoʻokō i nā koi no ka hoʻolālā hoʻolālā e like me AS1720.1
Loaʻa ka HW LVL terminator ma nā nui āpau a he ʻāpana ia o ka laulā Carter Holt Harvey Terminator.Hana ʻia ʻo HW H2-S Terminator e kūʻē i nā termite ma ka hema o ka Tropic of Capricorn.Hoʻohana ʻia ka lāʻau lapaʻau i ka laina glue i ka wā o ka hana ʻana e hoʻokō i ka pale termite piha i ke kumu o ka lāʻau.ʻAʻole koi ʻia ke sila hou aʻe ma nā ʻoki ʻoki, nā lua a i ʻole nā notches.Loaʻa nā pae lapaʻau ʻē aʻe mai nā mea hoʻolako ma ke noi, akā ua kaupalena ʻia ka mālama ʻana i ka hoʻohana ma luna o ka honua.ʻAʻole hiki ke mālama koke ʻia ka hySPAN no nā noi pili honua.
Hana ʻia ʻo HW LVL me ka hoʻohana 'A' Bond me ka liʻiliʻi o 0.5mg/l Formaldehyde (e like me E0) mai ka huahana hope loa.
lvl hale ʻano lāʻau laminated veneer
No ka hōʻoia maikaʻi ua hana ʻia ka laulā HW me nā kaʻina loiloi kūʻokoʻa a me ka hōʻoia huahana.Hoʻomaopopo ʻo Carter Holt Harvey i ka loaʻa ʻana o kāna lāʻau mai nā ululāʻau i mālama ʻia a hāʻawi iā FSC 'Chain of Custody' i hōʻoia ʻia ma ke noi.
Hoʻohana ʻia ʻo HW LVL me kahi helehelena papa hana a ʻaʻole i hoʻohana maʻamau ʻia i nā noi hiʻohiʻona a i ka manawa o ka hoʻouna ʻana mai kahi kahua hana i loaʻa ka maʻi ma waena o 8-15%.

Ua pena ʻia kā mākou LVL formwork beam i nā kala no ka pale ʻana i ka wai a me ka mākaukau mākaukau.Loaʻa iā HW nā ʻaoʻao chamfered no ka maʻalahi o ka lawelawe ʻana a me ka hoʻopau ʻana i ka pena wai.Hōʻike ka HW i kahi hoʻomaikaʻi nui ma mua o nā kaola lāʻau maʻamau a maʻalahi hoʻi e hoʻohana, ʻoi aku ka maʻalahi o nā mea ʻē aʻe.He ikaika, lōʻihi, hilinaʻi a hoʻohana hou.
Pōmaikaʻi o ka HW structural LVL
Hiki ke hana ʻia nā lāʻau liʻiliʻi i nā huahana LVL nui.
Loaʻa nā lōʻihi lōʻihi o LVL a hiki i 12m
Hiki ke hoʻonui ʻia ke kumu lāʻau ma ke koho ʻana a me ke koho ʻana i ka veneer no nā ʻāpana like ʻole o kahi ʻāpana keʻa LVL a me ka hana ʻana i nā huahana me nā waiwai like ʻole.
'A'ahu like 'ole ka waiwai o ka LVL no ka mea, ua helu mua 'ia nā papa lauwili o nā veneers lahilahi no ka 'o'ole'a (ka helu o ka ho'ololi no ka modulus o ka elasticity ma lalo o 5%).
Loaʻa i nā lālā LVL ka ikaika kiʻekiʻe ma muli o ka liʻiliʻi liʻiliʻi a me nā waiwai lāʻau randomized i nā ʻāpana lahilahi.
Hiki ke ʻoki ʻia a hana ʻia ʻo LVL me nā mea hana lāʻau maʻamau.
Hoʻohana pinepine ʻia ʻo LVL e hoʻokō i ka hoʻohana ʻana i ka lāʻau ʻili i ka hana hale.
Ka hoʻohana ʻana i ka LVL hoʻolālā HW
Ua kūpono loa ʻo LVL i nā noi aʻe
Nā lāʻau lāʻau a me nā kuʻi
Nā lintels, nā kaola a me nā lālā paʻi
ʻO nā chords Truss
Nā pā puka

ʻO nā papa pā
Pahu hana
Hoʻokiʻoki ʻia nā panela o LVL i nā lālā hoʻolālā i loaʻa ka ikaika kiʻekiʻe a me ka ʻoʻoleʻa.
Ua kūpono ʻo LVL i nā noi hoʻolālā e like me nā kaola, nā lāʻau a me nā kolamu i kahi ākea o nā hale me nā hale, nā hale kūʻai, nā ʻoihana a me nā hale kuaʻāina.ʻO kekahi LVL kūikawā he helu liʻiliʻi o nā veneers i waiho perpendicularly (cross banded).
Ma nā hale kūʻai pāʻoihana a i ʻole nā hana ʻoihana e hoʻohana pinepine ʻia ma ke ʻano he kumu lāʻau ʻokoʻa i ke kila kila a i ʻole nā mea i hoʻoikaika ʻia.
