Tsis ntev los no ntau thiab ntau tus neeg nyiam tsim tsev los ntawm cov khoom siv zoo ib puag ncig - ntoo. Glued laminated ntoo yog qhov kev xaiv zoo tshaj plaws.

Khoom zoo

Cov neeg tsim khoom koom nrog kev tsim vaj tsev ntoo tsis txhob nkees tham txog qhov zoo ntawm cov khoom siv ntuj no. Nws muaj peev xwm tswj tau qhov zoo ntawm cov av noo thiab qhov kub thiab txias hauv chav, muab huab cua pauv nrog ib puag ncig thiab tsuas yog muaj txiaj ntsig zoo rau tib neeg. Kev hloov zoo tshaj plaws rau cov cav ntoo yog glued ntoo.

Kev tsim cov khoom ntoo no yog ua raws li kev siv tshuab tshwj xeeb, ua tsaug rau cov khoom tsim nyog rau kev tsim kho tau txais ntawm cov khoom tsim tawm. Lub tsev yog tsim los ntawm nws nyob rau hauv lub shortest tau lub sij hawm. Ntawm lub hauv paus npaj txhij, ib lub tsev uas yooj yim hauv kev tsim qauv tuaj yeem tsim tau yuav luag ib hlis. Xws li cov qauv shrinks tsis ntau tshaj 1%. Thiab qhov no txhais tau hais tias nyob rau hauv cov tsev no koj tuaj yeem ua tiav tag nrho cov haujlwm tiav, nruab qhov rooj thiab qhov rais.

khoom siv yuav tsum

Nrog cov qauv ntoo ua ntau dua thiab nrov dua, ib qho kev cog lus ntawm kev lag luam yog kev tsim cov tsev los ntawm cov kab teeb ci. Koj tuaj yeem koom nrog kev tsim vaj tsev thiab tsim cov khoom siv nws tus kheej.

Ua ntej pib tsim cov ntoo, nws yog ib qho tsim nyog yuav tsum paub seb cov khoom siv twg yuav tsum tau ua rau lub hom phiaj no. Nws yog tseeb hais tias ntoo sawing tshuab, ziab chambers, tshwj xeeb presses yuav tsum tau. Tab sis qhov no tseem tsis tau tiav.

Yuav khoom siv rau kev tsim cov ntoo laminated, koj yuav tsum siv nyiaj. Yog li, koj yuav xav tau:

1) sawmill rau txiav ntoo;

2) ntau lub tshuab pom tsim los txiav cov kab loj loj rau hauv ib lub rooj;

3) folding lossis lub tshuab nqus tsev tsim rau stacking;

4) noo noo ntsuas, uas yog siv los tsis kam ntub dhau los yog, hloov pauv, overdried boards;

5) milling tshuab xav tau los ua cov txheej txheem ntawm cov lamellas;

6) planer thiab gluer, uas ib txwm nyob ntawm ib sab;

7) nias.

Dhau li ntawm qhov no, nws tseem yuav tsum tau teeb tsa txoj kab kev txhim kho uas txhua qhov tsis xws ntawm tsob ntoo yuav raug tshem tawm.

Technological process

Nws yog ib qho yooj yim los txiav txim seb cov khoom siv twg yog qhov xav tau txhawm rau ua cov kab teeb ci. Nws ntau lawm pib nrog sawing ntawm cov cav uas tau txais los ntawm lub rhiav mus rau hauv nyias boards. Nws yog lawv tom qabxa mus rau cov tshuab ziab khaub ncaws. Nws yog ib qho tsim nyog kom cov av noo nyob rau hauv lawv nyob rau theem ntawm 10%.

Tom qab ziab kom tiav, cov laug cam raug kuaj xyuas thiab tsis lees paub. Cov khoom xaiv uas tsis muaj qhov tsis zoo yog kho nrog cov tshuaj tshwj xeeb - nplaim taws thiab tshuaj tua kab mob. Qhov no yog qhov tsim nyog kom cov ntoo tsis cuam tshuam los ntawm cov kab mob thiab kom tsis txhob hlawv.

Tsuas yog tom qab ua tiav cov theem no, cov kev cob qhia pib ua cov lamellas. Nyob ntawm seb qhov yuav tsum tau ua thickness ntawm cov cav, los ntawm 2 mus rau 5 boards tuaj yeem txuas ua ke ntawm qhov tawm. Lawv tau nteg nyob rau hauv xws li ib tug txoj kev uas cov ntoo fibers mus nyob rau hauv sib txawv cov lus qhia - qhov no muab lub zog zoo tshaj plaws ntawm xws li cov khoom xws li glued beams. Kev tsim khoom tiav ntawm cov cuab yeej tshwj xeeb - nias. Qhov no yog qhov tsim nyog txhawm rau txhawm rau txhawm rau txhawm rau txuas cov lamellas ua ke.

Hais txog qhov zoo ntawm cov khoom siv niaj hnub no, ntau tus neeg tsis nco qab hais txog kev ua haujlwm ntev. Yog li, ib lub tsev tsim los ntawm cov kab teeb ci yuav muaj tsib caug lossis txawm tias 70 feem pua muaj zog dua li qhov uas tau siv hauv kev tsim cov cav ntoo. Tsis tas li ntawd, qhov ntev ntawm cov khoom tuaj yeem ncav cuag 12 meters - nws yooj yim los siv rau kev tsim kho ntawm cov phab ntsa.

Lub tshuab tsim khoom ntawm cov ntoo laminated yog xws li tias nws tseem profiled thaum nws tsim khoom. Qhov no muab kev yooj yim ntawm kev sib dhos ntawm cov phab ntsa thiab lawv cov zog ntxiv. Profileing ntawm ib lub bar yog tsim los ntawm tshwj xeeb plaub-sided tshuab. Qhov zoo ntawm cov khoom tiav yuav nyob ntawm seb yuav ua li cas conscientiously tus nplaig-thiab-groovebar ntsiab. Thaum lub sij hawm tsim kho vaj tse, rwb thaiv tsev yog nteg nyob rau hauv lub xauv ntawm cov ntoo profile. Qhov no muab cov rwb thaiv tsev ntxiv thiab cov phab ntsa tsis muaj cua.

Qhov zoo ntawm cov tsev ntoo

Ib tug tuaj yeem tham txog qhov zoo ntawm txhua lub tsev ntoo tau ntev. Tab sis peb xav nyob rau hauv dab tsi zoo glued ntoo muaj. Kev tsim cov khoom siv no yuav tsum tau tsim nyob rau theem siab tshaj plaws. Tom qab tag nrho, qhov zoo ntawm cov kab tiav tiav nyob ntawm cov cuab yeej siv, kev tsim nyog ntawm cov neeg ua haujlwm koom nrog, cov neeg ua haujlwm impregnation thiab cov nplaum siv rau ntoo.

Yog tias cov ntoo zoo nkauj tau yuav los tsim lub tsev, cov kab nrib pleb yuav tsis tshwm nyob rau hauv cov phab ntsa ntawm lub tsev, lawv yuav tiv thaiv qhov kub thiab txias, siab lossis qis qis thiab tsim kom muaj kev nyob zoo tshaj plaws. xwm txheej.

Tsis tas li ntawd, cov tsev cav feem ntau hu ua cov neeg tseem ceeb. Cov khoom no tso cai rau koj los daws cov teeb meem tsim, thaum txhua lub tsev yuav zoo li tsis muaj txiaj ntsig.
