I-Laminated Veneer Lumber (LVL)
Incazelo Yomkhiqizo
Ugongolo lwe-LVL olugcwele lwe-Pine, uhlaka lwe-LVL, amapulangwe e-LVL noma izingodo ze-Strand/ izingodo ezinobunjiniyela/ugodo lokhuni olunjiniyela lokubumba i-LVL yesakhiwo se-LVL
I-HW structural laminated veneer lumber (LVL) ekhiqizwe ngokuhambisana ne-AS/NZS 4357 enezakhiwo ezinqunywe ngokuvumelana ne-AS/NZS 4063.2 futhi ngenxa yalokho ithobelana nezidingo zokwakheka kwesakhiwo ngokuhambisana ne-AS1720.1
I-HW LVL terminator itholakala ngawo wonke amasayizi futhi iyingxenye yohlu lwe-Carter Holt Harvey Terminator.I-HW H2-S Terminator iphathwa ngomuhlwa eningizimu yeTropic of Capricorn.Ukwelashwa kusetshenziswa ku-glue-line ngesikhathi sokukhiqiza ukuze kuzuzwe ukuvikelwa okugcwele kwe-termite kumgogodla we-beam.Akukho okunye ukubekwa uphawu okudingekayo emaphethelweni asikiwe, emigodini noma kumanotshi.Amanye amazinga okwelashwa ayatholakala kubahlinzeki ngesicelo, kodwa ukwelashwa kukhawulelwe ekusebenziseni ngaphezu komhlabathi.I-hySPAN ayikwazi ukulashwa kalula ezicelweni zokuxhumana zasemhlabeni.
I-HW LVL yakhiwe kusetshenziswa i-'A' Bond ene-Formaldehyde engaphansi kuka-0.5mg/l (okulingana ne-E0) evela kumkhiqizo wokugcina.
i-laminated veneer lumber uhlobo lwesakhiwo lvl
Ukuze uthole ukuqinisekiswa kwekhwalithi uhla lwe-HW lwenziwa ngezinqubo zokucwaninga ezizimele kanye nesitifiketi somkhiqizo.I-Carter Holt Harvey iqinisekisa ukuthi izinkuni zayo zitholakala ngokusemthethweni emahlathini aphethwe futhi inikeza i-FSC 'Chain of Custody' egunyazwe uma icelwa.
I-HW LVL ikhiqizwa inobuso bezinga lesakhiwo futhi ayivamisile ukusetshenziswa ezinhlelweni zokubukeka futhi ngesikhathi sokuthunyelwa endaweni yokukhiqiza inomswakama ophakathi kuka-8-15%.

Inzuzo ye-HW yesakhiwo se-LVL
Izingodo ezincane zingenziwa zibe imikhiqizo emikhulu ye-LVL.
Ubude obude be-LVL buyatholakala kufika ku-12m
Insiza yokhuni ingathuthukiswa ngokuhlela nokukhetha i-veneer yezingxenye ezahlukene ze-LVL cross section futhi kwenziwe uhla lwemikhiqizo enezakhiwo ezahlukene.
Izakhiwo zesakhiwo se-LVL zifana kakhulu ngoba izendlalelo ezingahleliwe zemifino emincane zihlelwa kusengaphambili ukuze zibe lukhuni (i-coefficient of variation ye-modulus yokunwebeka ngaphansi kuka-5%).
Amalungu e-LVL anamandla aphezulu ngenxa yokuhlukahluka okuphansi kanye nezakhiwo zokhuni ezingahleliwe ezingqimbeni ezincane.
I-LVL ingasikwa futhi ifakwe ngomshini ngamathuluzi avamile okwenza izinkuni.
I-LVL ivame ukusetshenziselwa ukugcwalisa ukusetshenziswa kwezingodo ezisahwe ekwakhiweni kwasekhaya.
Ukusetshenziswa kwe-LVL yesakhiwo se-HW
I-LVL ifaneleka ngokukhethekile kulezi zicelo ezilandelayo
Ama-rafts nama-joists
Ama-Lintels, imishayo kanye namalungu ozimele
Ama-chords ama-truss
Amafreyimu ephothali
I-imishayo
Ibhokisi-imishayo
Amapulangwe esikafula
Umsebenzi wefomu
Amaphaneli e-LVL asikwa abe amalungu esakhiwo anamandla aphezulu nokuqina.
I-LVL ifanele ukusetshenziswa kwesakhiwo njengemishayo, amapulangwe namakholomu ezinhlobonhlobo zezakhiwo ezihlanganisa izindlu, izakhiwo zezohwebo, zezimboni nezasemaphandleni.Enye i-LVL ekhethekile inenani elincane lama-veneers abekwe nge-perpendicularly (ahlanganiswe nge-cross banded).
Ezakhiweni zezentengiselwano noma zezimboni kuvame ukusetshenziswa njengendlela ehlukile yokhuni ensimbi yesakhiwo noma ukhonkolo oqinisiwe.
Ukupakisha kanye Nokufakwa Kweziqukathi
