Laʻau Laʻa Laminated Veneer (LVL)He lāʻau i hana ʻia me ka ikaika kiʻekiʻe i hana ʻia e ka hoʻopaʻa ʻana i nā veneer veneer he nui ma ka papa me ka hoʻohana ʻana i nā mea hoʻopili.Ua hoʻomohala ʻia ʻo LVL e hoʻohana i nā ʻano lāʻau hou a me nā lāʻau liʻiliʻi ʻaʻole hiki ke hoʻohana ʻia e hana i nā lāʻau sawn paʻa.ʻO LVL kahi kumu kūʻai kūpono a paʻa i ka hale kūkulu e hāʻawi ana i ka ikaika a me ka hilinaʻi kiʻekiʻe i ka wā e hoʻohana ʻia ai i nā noi hana.
Nā hiʻohiʻona Laminate Veneer Laminate (LVL).
No ka Structural Composite Lumber (SCL) ka māhele LVL a ua hana ʻia mai nā veneer lāʻau maloʻo a kālai ʻia, nā ʻāpana a i ʻole nā lau.
Hoʻopaʻa ʻia nā veneers a hoʻopaʻa pū ʻia me kahi mea hoʻopaʻa pale pale.Hoʻopaʻa ʻia nā veneers ma ka ʻaoʻao hoʻokahi, ʻo ia hoʻi, ʻo ka hua o ka lāʻau ke kū pololei i ka lōʻihi o ka blank (ʻo ka blank ka papa piha i hoʻopaʻa ʻia i loko).
ʻO ka veneer i hoʻohana ʻia e hana i ka LVL ʻaʻole ia ma mua o 3 mm mānoanoa a hana ʻia me ka ʻenehana spin-peeling.Hoʻomākaukau maikaʻi ʻia kēia mau veneers, nānā ʻia no nā hemahema, ʻike ʻia no ka ʻoluʻolu a ʻokiʻoki me ka hoʻohana ʻana i nā ʻāhi rotary i ka laulā like me 1.4 m no ka hana LVL.
Hiki ke popopo ka LVL i ka wā e ʻike ʻia ai i ka ʻoluʻolu kiʻekiʻe a i hoʻohana ʻia paha i nā wahi unventilated.No laila, pono e mālama ʻia ʻo LVL me kahi mea mālama i mea e pale ai i ka palaho a i ʻole ka infestation ma ia mau noi.
Hiki i ka LVL ke ʻeli, ke kui a me ka wili ʻia me nā mea hana maʻamau.Hiki ke paʻi ʻia nā puka i loko o kēia mau lālā no nā lawelawe hoʻonohonoho.
Hana ʻia nā ʻāpana LVL a i ʻole nā blanks i ka mānoanoa mai 35 a 63 mm a i ka lōʻihi a hiki i 12 m.
Ua like ke pale ahi LVL me ka lāʻau paʻa a lohi ka charring a hiki ke wānana.Hoʻololi nā kumukūʻai ma muli o ke ʻano o ka lāʻau i hoʻohana ʻia a me ka nui o nā lālā.
No ka mea ua kuhikuhi ʻia nā veneers ma LVL i ka ʻaoʻao like, kūpono loa lākou no ke kūkulu ʻana i ka beam.Loaʻa i nā kaola LVL ka lōʻihi, ka hohonu a me ka ikaika no ka lawe pono ʻana i nā ukana ma luna o nā manawa lōʻihi.
Nā pōmaikaʻi o LVL
Loaʻa iā LVL ka ikaika nui a me ka ratio paona, ʻo ia hoʻi, ʻoi aku ka ikaika o LVL me nā ana liʻiliʻi ma mua o ka mea paʻa.ʻOi aku ka ikaika e pili ana i kona kaumaha.
ʻO ia ka mea lāʻau ikaika loa e pili ana i kona mānoanoa.
ʻO LVL kahi huahana lāʻau nui.Hiki ke hoʻohana ʻia me ka plywood, lāʻau a i ʻole oriented strand board (OSB).
Ma muli o ka mea hana, hiki ke hana ʻia ʻo LVL i nā pepa a i ʻole nā billet o ka nui a i ʻole ka nui.
Hana ʻia ʻo LVL mai nā mea lāʻau o ka maikaʻi like ʻole a me nā hemahema liʻiliʻi.No laila, hiki ke wānana maʻalahi ko lākou mau ʻano mechanical.
Hiki i ka LVL ke hana maʻamau e like me nā koi hoʻolālā.
Ka hoʻohana ʻana o LVL i ka Architecture
Hiki ke hoʻohana ʻia ka LVL no ka hana ʻana i nā I-beams, beams, columns, lintels, road markings, headers, rim panels, formwork, floor supports and more.Ke hoʻohālikelike ʻia me ka lāʻau paʻa, ʻo ka ikaika tensile kiʻekiʻe o LVL he koho maʻamau ia no ke kūkulu ʻana i nā pahu, purlins, truss chords, pitched rafters, a me nā mea hou aku.
Pono ʻo LVL i ka mālama pono a me ka mālama ʻana i nā koi e pale i nā pilikia warping.ʻOiai ʻoi aku ka liʻiliʻi o ka LVL i ka hana ʻana, pono ia i kahi hoʻopukapuka mua kiʻekiʻe.
