** Cov Lus Cim Archive: ** Cov ntawv sau khaws cov ntaub ntawv keeb kwm thiab cov duab los ntawm cov ntawv thawj. Lawv tsis tau raug tshuaj xyuas thiab tsis sawv cev rau qhov project tam sim no, kev suav zoo li qub, hluav taws xob specification, kev tshaj tawm ib puag ncig lossis kev kwv yees tus nqi. Rau ib daim ntawv thov tshwj xeeb, cov kev cai siv tau, cov chaw tsim khoom cov ntaub ntawv thiab cov kws tshaj lij tso cai tsim nyog yuav tsum tau ua.
CLT vaj huam sib luag thiab cov qauv tsim ntawm CLT cov tsev tsis tau nthuav tawm raws li ib feem ntawm kev tshaj tawm pej xeem tam sim no ntawm Savo Kusić. Kev tsom xam tam sim no yog lub qhov rais thiab qhov rooj.
Nyob rau hauv tsab xov xwm dhau los “Tshiab kev tsim kho tshuab - CLT” peb tau qhia koj txog cov ntsiab lus ntawm kev tsim kho CLT, thiab hauv cov ntawv no peb yuav sau rau qhov zoo tshaj plaws uas muaj los ntawm CLT engineering.
Txoj cai thaum pib, peb yuav taw qhia tias txhua qhov txiaj ntsig tau zoo tsim nyog thiab nrog txhua txoj kev kawm ntawm daim teb no, cov txiaj ntsig tau nce ib teev los ntawm ib teev. Txawm li cas los xij, peb yuav qhia rau tam sim no 6 qhov pom tseeb tshaj plaws.
Kev siv tshuab ntawm ntau txheej glued ntoo panels sawv cev rau niaj hnub siv tshuab niaj hnub no thiab ib yam dab tsi uas yuav muaj txiaj ntsig zoo rau yav tom ntej. Tshawb nrhiav hauv qab no yog CLT pheej yig tsuas yog rau cov neeg uas muaj hnab ris tob.
Advantage 1 - Sustainability
Lub durability ntawm ntoo twb paub zoo heev, tab sis nws tsis yog phem los rov ua dua. Ntoo ua zoo li daim txhuam cev uas absorbs carbon dioxide los ntawm huab cua. Thaum nqus cov pa roj carbon dioxide, tsob ntoo ib txhij tso pa oxygen rau hauv huab cua. Thaum cov ntoo “nqus” cov pa roj carbon monoxide, nws yog tom qab tso tawm ntawm cov ntoo tsuas yog tias nws qhuav lawm los yog nws raug hlawv. Thaum cov ntoo ua tiav mechanically, carbon dioxide yog daig hauv cov khoom molded.
Los ntawm kev siv cov khoom siv ntoo rau kev tsim kho, cov khoom siv yuav txo cov pa roj carbon dioxide:
- 1m3 CLT panels yuav tshem tawm 0.8 tons ntawm carbon dioxide los ntawm huab cua, yog li 1m3 CLT panels yuav muaj qhov nruab nrab ntawm 240 rau 250kg carbon dioxide nyob rau hauv lawv.
- Kev tsim cov cement tau ua rau emission ntawm 870kg carbon dioxide ib tuj ntawm cov cement (“_Kev lag luam cement muaj lub luag haujlwm tseem ceeb hauv kev hloov pauv huab cua”, Dr. Robert McCaffrey rau “Cement thiab txiv qaub” magazine
- Kev tsim cov cement tsim txog 1.75 tonnes ntawm carbon dioxide emissions ib tonne ntawm steel tsim (The Carbon Trust)
- Granular slag (tus qauv sib xyaw ntawm 40-50%) tuaj yeem txo cov pa roj carbon dioxide, tab sis tsuas yog hais txog 100-130kg ib tuj (Ecocem)
CLT ntoo vaj huam sib luag tuaj yeem tsim tau siv cov cuab yeej ua pa phem, tsis tshua muaj zog, dej tshiab tsawg thiab xoom feem pua pov tseg hauv kev tsim khoom.
Advantage 2 - Cov yam ntxwv durability
Multi-layer adhesive structural panels tuaj yeem siv rau cov khoom siv hauv tsev (phab ntsa, pem teb, ru tsev) lossis ua ib feem ntawm kev tsim vaj tsev, thiab ua tsaug rau cov txheej txheem tsim khoom “décorative lamination”, nws muaj peev xwm tsim cov vaj huam sib luag ruaj khov ntawm ntau yam duab zoo nkauj. Lub siab nruj ntawm cov panels muab qhov tseem ceeb robustness thiab cov ntsiab lus ntawm phab ntsa uas tuaj yeem txuas ntxiv ua cantilever. Cov txheej txheem muaj peev xwm ntawm cov hniav laminated ntoo panels zoo ib yam li cov pob zeb thiab tuaj yeem siv rau cov ntawv zoo sib xws.
Ib qho kev txhawj xeeb loj tshaj plaws rau cov neeg siv khoom kawg nrog cov khoom siv ntoo thiab ntoo khaub lig laminated yog hluav taws. Qhov ntshai yog tias lub tsev ua los ntawm cov ntoo yuav hlawv tag nrho yog tias muaj hluav taws, tab sis qhov tseeb, nws yog ntoo; ib yam li iav yuav yaj, ib yam li pob zeb yuav tawg. Ib lo lus nug tseem ceeb yog qhov tseeb qhov kev kwv yees ntawm cov khoom siv hauv qhov hluav taws kub thiab ntev npaum li cas nws tuaj yeem hlawv yam tsis poob nws cov khoom. Ntoo yog qhov tseeb heev nyob rau hauv qhov hluav taws kub - txheej txheej ntawm ntoo khaub lig-laminated ntoo vaj huam sib luag yuav ntes hluav taws ua ntej, ces tsim ib txheej ntawm rwb thaiv tsev uas muab 30,60 los yog ntau feeb ntawm hluav taws kub, nyob ntawm seb tus naj npawb thiab qhov loj ntawm lub vaj huam sib luag.
Advantage 3- Kev tsim kho yooj yim
CLT cov tshuab suav nrog hauv MMC thev naus laus zis vim txoj kev tsim kho yooj yim thiab nrawm. Cov vaj huam sib luag feem ntau yog nruab nrog tus kheej tapping ntoo screws thiab steel kev txhawb nqa, uas ua rau cov txheej txheem nrawm dua piv rau cov khoom siv hauv tsev. Video http://youtu.be/bURy80-ZE7Y qhia txog kev tsim kho vaj tse nyob hauv Highgate (United Kingdom) tsim los ntawm “BLISS” siv CLT panels muab los ntawm “KLH UK”. Vim qhov zoo tolerances ntawm lub panels ua nyob rau hauv lub Hoobkas, sealing ie. huab cua nruj ntawm cov pob qij txha tuaj yeem ua tiav nrog ua npuas ncauj ua ntej thiab / lossis daim kab xev tshwj xeeb uas yog glued hla cov pob qij txha sab nraud. Raws li lawv sib txuas, laminated panels sai sai muab cov khoom qhuav, huab cua-resistant yam tsis muaj khoom siv ib ntus. Qhov no muab cov txheej txheem tiv thaiv sab nraud uas ua haujlwm zoo li lub plhaub uas tuaj yeem ua dej tsis tau sai heev. CLT panels tuaj yeem xa mus rau qhov sib txawv, yog li tus neeg siv khoom muaj lub sijhawm los xaiv seb nws puas xav tau ib puag ncig uas exudes lub ntuj zoo ntawm ntoo, los yog seb phab ntsa yuav npog nrog lwm cov khoom. Raws li cov vaj huam sib luag tau tsim los ntsuas hauv lub Hoobkas, cov khoom pov tseg ntawm qhov chaw teeb tsa yog qhov tsawg thiab cov txheej txheem kev tsim kho yog nyob ntsiag to thiab huv si nrog cov cuab yeej tsawg thiab cov cuab yeej piv rau cov qauv kev tsim kho. Kev siv CLT system txhawb kev lees paub ntawm cov neeg cog lus.
Advantage 4 - Txuag Nyiaj
Tus nqi ntawm kev tsim lub tsev siv CLT vaj huam sib luag thev naus laus zis yuav tsum tau saib hauv cov ntsiab lus dav dua thiab ntev dua. Dab tsi yog muab los ntawm kev suav tam sim no ntawm kev tsim kho, thaum lub sij hawm siv lub tsev, dhau los ua ib qho kev suav uas yog amortized heev rau cov neeg siv. Kev txuag nqi nrog qhov kev tsim kho no tau txais thoob plaws hauv lub neej ntawm qhov project tsim. Kev tsim kho ceev txo qhov kev tsim kho tag nrho, uas ua rau txo qis ntawm tus neeg cog lus ua haujlwm ua ntej, txo tus nqi ntawm tus neeg cog lus thiab txo cov nqi tsim kho rau cov neeg siv khoom kawg. Kev txo cov nqi tsim kho tag nrho yog raws li:
- Tsawg qhov hnyav hauv tag nrho cov qauv ua rau muaj kev lag luam ntau dua substructure / foundation tsim (tsawg pob zeb)
- Kev npaj yuav nrawm dua; piv txwv li qhov rais tuaj yeem xaj ua ntej raws li muaj qib siab ntawm qhov raug muab los ntawm precision CNC txiav
Qhov zoo ntawm 5 - Txuag sijhawm
Raws li twb tau piav lawm, qhov ua tau zoo ntawm kev tsim kho nrog cov ntoo panels no tuaj yeem ua kom txuag tau lub sijhawm tseem ceeb ntawm qhov project. Raws li cov ntaub ntawv uas tau tsim nyob rau hauv factories, nws tsis xav tau lwm yam ntaub ntawv thaum lub sij hawm tsim kho, yog li ntawd tsawg tus neeg koom nyob rau hauv kev tsim kho, thiab CLT panels tuaj txog ntawm qhov chaw npaj rau kev sib dhos. Cov nyiaj khaws cia hauv qab no tau ua tiav:
- Kev tsim kho - txog 30-50% sai dua
- Kev txhim kho qhov rais thiab qhov rooj- 20-30% sai dua
- Installation- 20-30% sai dua
Qhov zoo ntawm 6 - Tsim kom yooj yim
Txoj hauv kev uas CLT cov vaj huam sib luag tuaj yeem raug txiav thiab xa mus tso cai rau kev tsim qauv yooj yim thiab kev ywj pheej ntawm kev tsim vaj tsev.
Txhawm rau siv lub peev xwm loj ntawm CLT, nws yog ib qho tseem ceeb uas yuav tsum muaj cov qauv tsim kom pom tseeb uas tau kos npe ua ntej los ntawm cov neeg siv khoom thiab pab pawg tsim qauv, vim tias qhov tseeb thiab qhov tseeb ntawm cov phiaj xwm phiaj xwm nws tus kheej (kev npaj) tseem ceeb npaum li kev tsim kho nws tus kheej.
Ntoo yog cov khoom siv uas yooj yim rau kev ua, thiab niaj hnub CNC tshuab muab qhov ua tau zoo ib yam ntawm cov khoom haum thiab nkhaus, txoj kev tsim qauv thiab cov kws tsim qauv pom nws.
Txog tam sim no, dhau 280 ntawm cov tsev zoo li no tau tsim nyob hauv Tebchaws Askiv. Txij li thaum paub txog cov tswv yim zoo li no tau loj hlob nyob rau xyoo tas los no, ntau lub tuam txhab tau tsim cov khoom siv zoo li no. Tus kws kes duab vajtse Alek de Rijke hais tias: “Yog 19. xyoo pua yog lub xyoo pua ntawm cov hlau, 20. lub xyoo pua ntawm pob zeb, ces **21. xyoo pua yog hais txog lub tsev nrog ntoo **”.
