I-Laminated Veneer Lumber (LVL)iwukhuni olwakhiwe ngamandla aphezulu olukhiqizwa ngokuhlanganisa ungqimba lwama-veneer amaningi ngongqimba kusetshenziswa izinto ezinamathelayo.I-LVL yasungulwa ukuze isebenzise izinhlobo ezintsha nezihlahla ezincane ezingeke zisetshenziselwe ukwenza izingodo ezisahayo eziqinile.I-LVL iyimpahla yokwakha engabizi kakhulu futhi esimeme enikeza amandla aphezulu esakhiwo nokuthembeka uma isetshenziswa ezinhlelweni zokusebenza.
Izici ze-Laminate Veneer Laminate (LVL)
I-LVL ingaphansi kwesigaba se-Structural Composite Lumber (SCL) futhi yenziwe ngamapulangwe okhuni omisiwe futhi ahlelwe ngokwezinga, imicu noma amashidi.
Ama-veneers agqinsile futhi ahlanganiswe ne-adhesive ukumelana nomswakama.Ama-veneers ambondelene aqonde ohlangothini olufanayo, okungukuthi uhlamvu lwezinkuni luhambisana nobude bendawo engenalutho (okungenalutho yibhodi eliphelele afakwe kulo).
I-veneer esetshenziselwa ukwenza i-LVL ingaphansi kuka-3 mm ubukhulu futhi ikhiqizwa kusetshenziswa ubuchwepheshe be-spin-peeling.Lawa ma-veneers alungiswe kahle, askenwe ukuthi awasebenzi yini, ahlaziywe ukuze athole umswakama futhi asikwe kusetshenziswa izikere ezijikelezayo zibe ububanzi obulingana no-1.4 m ekukhiqizeni i-LVL.
I-LVL isengozini yokubola lapho ibekwe kumswakama ophezulu noma isetshenziswa ezindaweni ezingenawo umoya.Ngakho-ke, i-LVL kufanele iphathwe ngesilondolozi ukuze kuvinjelwe ukubola noma ukuhlasela kwezicelo ezinjalo.
I-LVL ingasaha, ibethelwe futhi ibholwe ngamathuluzi ajwayelekile.Izimbobo zingabhodlozwa kulawa malungu ukuze kutholwe izinsiza zokufaka.
Amashidi e-LVL noma izikhala zenziwa ngogqinsi ukusuka ku-35 kuye ku-63 mm futhi ngobude obufika ku-12 m.
Ukumelana nomlilo kwe-LVL kufana nokhuni oluqinile futhi ukushaja kuhamba kancane futhi kuyabikezelwa.Amanani ayahlukahluka kuye ngohlobo lokhuni olusetshenzisiwe kanye nobukhulu bamalungu.
Njengoba ama-veneers ku-LVL aqondiswe ohlangothini olufanayo, afaneleka ngokukhethekile ukwakhiwa kwemishayo.Imishayo ye-LVL inobude, ukujula namandla okuthwala kahle imithwalo phezu kwezikhala ezinde.
Izinzuzo ze-LVL
I-LVL inamandla amakhulu we-dimensional kanye ne-weight-strength ratio, okungukuthi, i-LVL enobukhulu obuncane inamandla amakhulu kunempahla eqinile.Inamandla futhi uma iqhathaniswa nesisindo sayo.
Iwukhuni oluqinile oluhlobene nokuminyana kwalo.
I-LVL iwumkhiqizo wokhuni onemisebenzi eminingi.Ingasetshenziswa nge-plywood, izinkuni noma ibhodi le-strand oriented (OSB).
Kuye ngomkhiqizi, i-LVL ingakhiqizwa ngamashidi noma amabhilethi cishe anoma yimuphi usayizi noma ubukhulu.
I-LVL ikhiqizwa ngezinto zokhuni zekhwalithi efanayo kanye nokukhubazeka okuncane.Ngakho-ke, izakhiwo zabo zemishini zingabikezelwa kalula.
I-LVL ingenziwa ngokwezifiso ngokuya ngezidingo zesakhiwo.
Ukusetshenziswa kwe-LVL ku-Architecture
I-LVL ingasetshenziswa ukwenza imishayo ye-I, imishayo, amakholomu, amakholamu, izimpawu zomgwaqo, izihloko, ama-rim panel, formwork, izisekelo zaphansi nokunye.Uma kuqhathaniswa nokhuni oluqinile, amandla aqinile e-LVL akwenza kube ukukhetha okuvamile ekwakheni ama-trusses, ama-purlins, ama-truss chords, amapulangwe agxunyekiwe, nokuningi.
I-LVL idinga ukuphathwa okufanele kanye nezidingo zokulondoloza ukuze igweme izinkinga ezimpintshanayo.Noma i-LVL ishibhile ukuyikhiqiza, idinga ukutshalwa kwezimali okukhulu kokuqala.
