Glued beams: flaws thiab zoo

Nws yeej ib txwm ntseeg tias ntoo yog cov khoom tsim rau kev tsim kho. Nws yog txhua yam hais txog nws qhov kev phooj ywg, kev thermal conductivity, naturalness thiab, tau kawg, ntuj kev zoo nkauj. Cov teeb meem ntawm cov khoom siv hauv tsev no tsis tshua muaj me me, thiab txawm nrog cov neeg ntawd, cov neeg tau kawm los mus sib ntaus.

Cov khoom ntawm cov cim tshiab - glued nqaj

Cov neeg feem coob, tshwj xeeb tshaj yog cov pejxeem ntawm megacities, npau suav ntawm kev tu tsiaj txhim ntawm vaj tse thiab kev nyob zoo dua qub. Txog rau hnub, kev cai ntawm kev sib tw ntawm ib-paus xyoo, ua ke nrog cov txheej txheem tsim tshiab, tso cai rau tsim cov tsev ntoo ntawm cov zoo zoo. Qhov nrov tshaj plaws thiab nrov nyob rau hauv kev tsim kho ntawm lub tsev glued ntoo, vim nws yog ntuj, ruaj thiab zoo nkauj. Tej lub tsev ua haujlwm tsis thim, muaj txoj haujlwm ntev ntev thiab npaj txhij rau kev lag luam thiab ua tiav txoj cai tom qab kev ua tiav kev teeb tsa.

Ntau cov qauv

Cov khoom siv uas tsim los ntawm peb tau ua tiav raws li nram no: cov log uas tau pom ntawm cov laug cam, uas zoo li qub qhuav (noj rau hauv cov paj ntoo), txog li 10-12% noo noo, thiab mechanically ua tiav, raws li qhov ua rau tag nrho cov ua tau raug tshem tawm. Tom qab muaj kev ziab zoo, cov ntoo hla ib daim duab kos rau qhov txheeb xyuas thiab tshem tawm cov cheeb tsam nrog cov pob txha tuag, cov ntaub qhwv thiab cov nqaij fungal.

Tom qab ntawd cov laug cam (hauv txhais tau tias lawv hu ua lamellas) yog sib xyaw ua ke nrog kev sib txuas lus tshwj xeeb thiab raws li cov cuab yeej siv rau cov khoom siv no. Nyob rau hauv tiav lawm beam lawv muaj peev xwm yuav ntau, qhov ntev ntawm lub blanks tau ncav cuag txog li 18 meters. Tsis tas li ntawd, cov ntoo kab teeb raug qhuav, thiab tsuas yog tom qab uas cov nqaj glued yog txheeb, uas yog, nws tau txais cov qauv li ib txwm.

Cov ntaub ntawv rau laminated veneer lumber

Rau qhov tsim tau thiab siv thiab ua cov cav ntoo, cov kab tsim muaj ntev ntev, siv ntoo, txiv ntoo, cedar thiab larch. Kev siv cov tseem ceeb thiab, raws li, ntau kim hom ntoo - ib qho tsawg kawg tshwm sim. Yog vim li cas ib tug nqi siab. Xws li tus nqi yog siv tsis tau rau cov neeg ua haujlwm hauv tsev. Txawm hais tias tej ntaub ntawv pom lawv cov neeg muas zaub, thiab nws tshwm sim ntau zaus.

Qhov zoo ntawm cov kab teeb

Zoo li txhua yam khoom siv hauv tsev, muaj cov kab kos zoo zoo thiab qhov tsis zoo. Ua ntej, cia saib nws qhov zoo:

1. Lub tsev ntoo ua cov laminated veneer lumber tau yooj yim kom sib sau tau thiab sib sau ua ke, thiab thawb thiab shrinkage tsawg dua.

2. Cov khoom siv suab tsis yog deformed thiab tsis hloov nws cov duab.

3. Lub sijhawm ua haujlwm, nws tsis muaj kev tiv thaiv los ntawm cov kab tawg. Qhov nws saum npoo yog du thiab du, tsis yog yuav tsum tau ntxiv kev ua thiab siv zog thiab siv cov nyiaj ua haujlwm tiav.

4. Cov khau glued muaj qhov zoo ntawm cov av noo, uas tiv thaiv rotting thiab pom nyob rau hauv nws ntawm fungal microorganisms thiab cov teeb meem kab mob.

5. Cov ntaub ntawv no tuaj yeem siv los siv cov dej num nyuaj.

Ntseeg

Txawm li cas los xij, peb tsis tuaj yeem hais tias tsuas yog cov yam ntxwv zoo yog cov nqaj tawv. Disadvantages kuj muaj qhov chaw ua, ntawm no yog qee yam ntawm lawv:

1. Tus nqi siab ntawm cov ntaub ntawv glued. Xws li ib lub tsev yuav raug nqi 2 zaug ntau tshaj li cov nqi ntawm cov ntawv sau tsis tau.

2. Raws li qhov tseeb tias cov cuab yeej tsim tawm tshiab heev, cov ntaub ntawv ntawm kev coj cwj pwm ntawm cov khoom no ntawm cov sij hawm sib txawv (piv txwv li, tom qab 30-50 xyoo) tseem tsis tau muaj, vim tias nws cov khoom tsis tau kawm.

3. Siv hauv qhov txheej txheem ntawm cov kua nplaum. Tis ntawm qhov tseeb hais tias lub nplaum sib txuas ua raws li cov kev cai, rau qhov kev sib haum xeeb ntawm ecological tus glued beam yuav plam mus rau qhov zoo tib yam qis qis los yog cav, txij thaum lawv tsis tag dawb ntawm cov tshuaj zoo sib xws. Kev siv kua nplaum yuav ua rau qee cov yam ntxwv, nyob rau hauv txhua rooj plaub, pa pauv thiab noo noo tsis ua rau tag nrho. Tsis tas li ntawd, qhov microclimate hauv thaj chaw tseem raug ua txhaum.

Dab tsi yog vim li cas rau cov nqi siab ntawm cov ntaub ntawv hauv tsev?

Txawm tias muaj tseeb tias qhov muaj siab xav ua neej nyob hauv ib lub tsev ntawm cov khoom siv yog loj heev, ntau tus neeg raug kev cuam tshuam los ntawm lawv cov nqi. Tseeb, qhov nqaj hlau nplaum, qhov shortcomings uas tau txiav txim siab me ntsis ntxiv, yog cov kim tshaj txhua yam kev sib txuas ntawm wood - cav, cav, thiab lwm yam.

Tus nqi siab ntawm cov ntaub ntawv no yog undoubtedly cuam tshuam los ntawm cov txheej txheem ua txoj haujlwm ntawm nws cov khoom. Ntau cov nqi tsim kho, nce, noj cov ntoo thiab cov khoom siv, uas tsis tuaj yeem cuam tshuam txog cov nqi.

Qhov zoo tshaj plaws ua tau zoo tshaj plaws, muaj qhov tsis zoo, thiab tag nrho lawv dag rau qhov chaw tsis muaj kev tsim khoom, tsis muaj kev ncaj ncees, tsis muaj kev ntseeg, tsis ua haujlwm hauv xaiv cov cuab yeej thiab lwm yam ntaub ntawv, thiab lwm yam. Ib txhia siv lawv cov ntaub ntawv tsis zoo, sim txuag nyiaj thiab Simplify tsim txoj kev. Txawm li cas los xij, tus tswv tsev yuav khuv xim nws, raws li nws lub tsev yuav ploj tag thiab tawg. Ntawm qhov tod tes, qhov sib tsoo no tau ua suab tsis tau raws li cov txheej txheem deformation, nws yog qhov ntev dua piv rau lwm cov sawn ntoo. Nws hloov tawm tias tus nqi nplua nuj yog qhov ncaj ncees. Tab sis tsawg tus nqi, nyob rau hauv tsis tooj, yuav tsum ceeb toom.

Cov nqaj puas ruaj ruaj?

Feem ntau muaj kev tsis pom zoo txog kev nyab xeeb rau tib neeg thiab thaj chaw ntawm cov khoom siv xws li nkhaus kab laum. Qhov laj thawj rau cov kev tsis sib haum no yog siv cov kua nplaum rau hauv cov txheej txheem ntau lawm.

Nws yuav tsum tau nyob rau hauv lub hlwb hais tias cov khoom siv nyob rau hauv lub chaw ua khoom ntawm xws li ib tug bar muaj xws li cov ntaub ntawv nyob rau hauv ib txwm hauv paus. Nyob hauv qee txoj kev, kua nplaum yuav piv rau ib qho kev muaj zog thiab tiv taus ntau yam teeb meem ntawm cov ntoo ntoo. Tab sis txij li thaum cov nqaj nyom, qhov zoo thiab qhov tsis zoo ntawm peb tau pom, muaj ob peb lub khoob khau ua ke, tsis tas yuav tsum hais txog qhov zoo txav ntawm kev ya raws thiab cua. Li no, peb tuaj yeem kos cov nram qab no xaus: nws tsis yog siv raws li cov khoom ntoo, tab sis nws tsis tuaj yeem tsim kev puas tsuaj, vim tag nrho cov ntaub ntawv siv rau nws cov khoom yuav tsum tau ntawv pov thawj.

Raws li kev txheeb cais, ntau tus tswv tsev zoo tib yam thiab cov tuam txhab ua haujlwm tau xaiv cov laj kab nyom. Disadvantages (tawm tswv yim txog kev siv cov khoom siv no yog tseeb), tau kawg, muaj feem xyuam rau qee thaj chaw ntoo, tab sis qhov no tsis yog qhov tseem ceeb.

Ntau yam

Tseg ntau hom ntawm cov khoom siv no. Nyob ntawm qhov tsim thiab lub hom phiaj, lawv tuaj yeem faib ua 2 pawg:

1. Siv cov khoom siv rau cov phab ntsa ntawm pob zeb (rau qhov no siv qhov cub ua kom sov los yog qeeb qeeb).

2. Khoom siv uas rau kev tsim kho ntawm cais lug (bent thiab glued scantlings, joists etc.). Nrov tshaj plaws yog hom Finnish thiab German. Scandinavian glued beam, cov disadvantages ntawm uas tsuas yog hais tias nws yuav tsum tau ntxiv sealing rau nws (thiab feem ntau qhov no yog ib hom kev profile), tus so yog characterised muaj ob sab laterals thiab tshwj xeeb grooves. Cov khoom xws li txuas nrog lub khov khov muaj zog, thiab hauv nruab nrab yog qhov chaw rau kev ntim cov ntawv foob. Lub German profile yog pom zoo los ntawm sib txuas ua ke. Nws muab ntau qhov ntom nti tsis siv cov ntaub ntim khoom siv.

Kev tsim kho ntawm ib lub tsev ua los ntawm laminated veneer lumber

Lub zog ntawm txhua lub tsev pib nrog lub hauv paus, yog li nyob rau hauv txoj hlua glued nws yog qhov yuav tsum tau ua ntej tso lub hauv paus tsim nyog.
