Ntawm cov ntoo ua kev tsim kho, lub tsev ua cov tsev ntoo yog tshwj xeeb tshaj yog nrov, vim hais tias cov khoom no yog cov phooj ywg ib puag ncig thiab, tib lub sijhawm, muaj cov yam ntxwv zoo heev ntawm kev muaj zog, tiv taus kev ntxhov siab thiab txuag hluav taws kub. Muaj nws peb hom ntoo: ntuj noo, profiled thiab ci.
Cov Lus Qhia
Kauj ruam 1
Ib bar ntawm ntuj noo noo. Cov khoom siv nrov tshaj plaws thiab pheej yig. Nws yog qhov zoo dua los siv xws li bar yog tias koj npaj siab yuav nyob hauv tsev feem ntau yog nyob rau lub caij nplooj ntoo hlav thiab lub caij ntuj sov. Qhov cuam tshuam tseem ceeb ntawm cov ntoo no yog tias cov kab nrib pleb tshwm rau ntawm nws sab thaum lub sij hawm ziab, thiab tom qab ntsws (tom qab li 2-3 xyoos), yuav tsum tau txuas phab ntsa ntxiv lossis xaws sab nrauv.
Kauj ruam 2
Profiled beams Feem ntau, profiled kab teeb yog tsim los ntawm conifers los ntawm milling lossis phiaj xwm. Thaum lub sijhawm tsim khoom, xws li qhov bar tau muab cov qauv ntawm cov duab puab (qhov profile). Txawm hais tias nws tshwm sim tias sab hauv ntawm lub tsev ntoo muaj qhov chaw tiaj, thiab sab nraud ntawm lub tsev yog convex. Lub tsev ua los ntawm cov ntoo profiled zoo nkauj thiab zoo huv si thiab tsis tas yuav ua tiav xov ntxiv. Xaiv qhov ntawm lub tsev zoo li ntawd, koj txuag sijhawm rau nws txoj kev tsim kho. Ua tsaug rau qhov tshwj xeeb grooves, cov ntoo ntoo profiled tau yooj yim muab tais tau yooj yim zoo li cov menyuam yaus tsim qauv, qhov twg txhua qhov chaw haum zoo ua ke. Kev nrib pleb hauv tsev zoo li no yuav tsis tshwm sim, thiab txhua yam koj yuav tsum ua yog xuab zeb phab ntsa thiab taug kev nrog lawv cov tshuaj pleev xim lossis pleev xim. Koj tuaj yeem nyob hauv lub tsev zoo li no thaum lub caij ntuj no tsis muaj kev ntshai ntawm cua, kev nkag mus rau ya raws nruab nrab ntawm cov kab thiab qhov tsos ntawm foci ntawm kev lwj. profiled ntoo xaiv tau cov txheeb ze vaum.
Kauj ruam 3
Glued laminated ntoo. Glued laminated ntoo yog tsim los ntawm cov laug cam (lamellas), ua ntej ziab thiab them nrog cov tshuaj tua kab mob. Lamellas tiav yog glued rau hauv kab teeb. Hauv qhov no, thaum lub sijhawm ua haujlwm, lub tsev ua los ntawm cov ntoo laminated veneer lumber khaws nws cov qub qub. Yog li no, yog tias koj xav nyob hauv tsev tam sim ntawd tom qab nws tsim kho, ces lo rau cov ntoo laminated yog qhov kev xaiv zoo tshaj plaws, vim hais tias kev tshem tawm cov shrinkage (tsis pub ntau tshaj 1%), thiab koj yuav tsis pom ib zaug qhib qhov rooj lossis qhov rai qhib.
