OSB - pawg thawj coj saib xyuas txoj hlua - tau ntseeg tau nkag mus rau hauv kev tsim kho. Cov vaj huam sib luag no txawv txav los ntawm lwm cov vaj huam sib luag los ntawm lawv qhov loj me ntawm cov ntoo txua ntoo. Cov cuab yeej ua tau zoo tau muab los ntawm cov cuab yeej tsim khoom tshwj xeeb: txhua lub rooj tsavxwm muaj ob peb txheej ("ntaub pua plag") nrog cov nplais thiab cov ntoo ntoo sib txawv ntawm kev taw qhia, ua kom tsis muaj cov yas dag dag thiab nias rau hauv ib pawg.

OSBs tuab npaum li cas?

OSB cov laug cam sib txawv ntawm cov khoom siv ntoo txua ntoo tsis yog tsuas yog pom. Lawv yog cov yam ntxwv los ntawm:

• siab zog (raws li GOST R 56309-2014 qhov kawg khoov zog raws lub hauv paus tseem ceeb yog los ntawm 16 MPa txog 20 MPa);
• txheeb ze qhov sib txawv (ntom ntom piv rau ntoo ntuj - 650 kg / m3);
• kev tsim khoom zoo (yooj yim txiav thiab xyaum ua cov lus qhia sib txawv vim yog cov qauv sib xws);
• tiv taus noo, rot, kab;
• tus nqi qis (vim siv ntoo tsis zoo ua raw khoom).

Feem ntau, hloov ntawm OSB cov ntawv luv, pom lub npe OSB-phaj. Qhov tsis sib xws no yog vim lub npe European ntawm cov khoom siv no - Oriented Strand Board (OSB).

Txhua lub vaj huam sib luag tsim tau muab faib ua 4 yam raws li lawv lub cev thiab yam ntxwv yam ntxwv thiab lawv cov haujlwm ua haujlwm (GOST 56309 - 2014, p. 4.2) . OSB-1 thiab OSB-2 cov laug cam tau pom zoo tshwj xeeb rau cov xwm txheej ntawm cov av qis thiab ib txwm muaj. Rau cov txheej txheem thauj khoom uas yuav ua haujlwm hauv cov ntub dej, tus txheej txheem sau tseg kom xaiv rau OSB-3 lossis OSB-4.

Nyob rau thaj tsam ntawm Lavxias Federation, lub tebchaws tus qauv GOST R 56309-2014 tau siv, uas tswj cov txheej txheem kev tsim khoom rau OSB. Yeej, nws zoo ib yam nrog cov ntaub ntawv zoo sib xws EN 300: 2006 tau lees paub hauv Tebchaws Europe. GOST teeb tsa qhov tsawg kawg nkaus tuab ntawm daim ntawv nyias nyias ntawm 6 hli, qhov siab tshaj plaws - 40 hli hauv kev nce ntxiv ntawm 1 hli.

Hauv kev coj ua, cov neeg siv khoom nyiam cov vaj huam sib luag nrog cov tuab tuab ntawm 6, 8, 9, 10, 12, 15, 18, 21 mm

Qhov ntau thiab tsawg ntawm cov ntawv txheeb ntawm cov tuam txhab sib txawv

Tib GOST tsim kom pom tias qhov ntev thiab dav ntawm OSB cov ntawv tuaj yeem yog los ntawm 1200 hli lossis ntau dua nrog rau qib 10 hli.

Ntxiv rau Lavxias, European thiab Canadian cov tuam txhab tau sawv cev hauv kev lag luam hauv tsev.

Kalevala yog lub chaw tsim khoom vaj huam sib luag hauv tsev (Karelia, Petrozavodsk) . Qhov ntau thiab tsawg ntawm cov ntawv tsim tawm ntawm no: 2500 × 1250, 2440 × 1220, 2800 × 1250 mm.

Talion (Tver cheeb tsam, lub nroog Torzhok) yog lub tuam txhab Lavxias thib ob . Nws tsim cov ntawv ntawm 610 × 2485, 2500 × 1250, 2440 × 1220 mm.

OSB vaj huam sib luag tau tsim nyob hauv cov npe ntawm Austrian cov tuam txhab Kronospan thiab Egger hauv ntau lub tebchaws. Cov ntawv loj: 2500 × 1250 thiab 2800 × 1250 hli.

Lub tuam txhab Latvian Bolderaja, zoo li German Glunz, ua OSB cov laug cam ntawm 2500 × 1250 mm

North American cov tuam txhab ua haujlwm rau lawv tus kheej cov qauv. Yog li, Norbord slabs muaj qhov ntev thiab dav ntawm 2440 thiab 1220 mm, feem.

Tsuas yog Arbec muaj ob qhov sib txawv ntawm qhov ntau thiab tsawg, zoo ib yam nrog European.

Cov Lus Qhia Xaiv

Rau lub ru tsev uas muaj pob zeb, cov pob khaus feem ntau siv. Cov ntaub ntawv zoo li no rau kev vov tsev yuav tsum tsim kom muaj cov khoom ruaj khov, txawm tias yog lub hauv paus, uas OSB cov laug cam ua tiav. Cov lus pom dav dav rau lawv xaiv yog hais los ntawm kev txiav txim siab ntawm kev lag luam thiab kev tsim khoom.

Slab yam

Txij li thaum lub rooj sib txoos ntawm lub ru tsev, cov nplais, nrog qib siab ntawm qhov tshwm sim, tuaj yeem poob qis thaum nag lossis daus, thiab cov dej xau tsis suav nrog thaum lub sijhawm ua haujlwm ntawm lub tsev, nws raug nquahu kom xaiv ob hom pob zeb kawg.

Xav txog tus nqi siab ntawm OSB-4, cov neeg tsim khoom feem ntau nyiam OSB-3.

Slab tuab

Cov txheej txheem ntawm kev sib koom ua lag luam 17.13330.2011 (tab.7) tswj hwm tias thaum siv OSB-daim hlau ua lub hauv paus rau cov kab mob shingles, nws yog qhov tsim nyog los tsim cov av txuas mus ntxiv. Lub thickness ntawm slab yog xaiv nyob ntawm lub suab ntawm rafters:

Rafter suab, hli	Ntawv tuab, hli
600	12
900	18
1200	21
1500	27

Ntug

Kev ua ntug yog ib qho tseem ceeb. Cov phaj tau tsim ob qho tib si nrog cov tiaj tiaj thiab nrog cov zawj thiab cov npoo (ob- thiab plaub-sab), kev siv uas ua rau nws muaj peev xwm kom tau txais qhov saum npoo nrog qhov ua tau zoo tsis muaj qhov khoob, uas ua kom ntseeg tau tias txawm tias faib cov khoom thauj hauv cov qauv.

Yog li ntawd, yog tias muaj kev xaiv ntawm ntug du lossis nqaim, tom kawg yog qhov zoo dua.

Slab loj

Thaum sib dhos lub ru tsev, nws raug nquahu kom coj mus rau hauv tus account tias cov pob zeb feem ntau tau muab tso rau ntawm rafters ntawm sab luv, nrog ib lub vaj huam sib luag npog peb qhov dav. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov nplais tau txuas ncaj qha rau lub trusses nrog qhov sib txawv los txhawm rau txhawm rau txhawm rau deformation.

Txhawm rau kom txo qis kev ua haujlwm ntawm kev kho cov ntawv, nws raug nquahu kom siv cov ntawv uas muaj qhov loj me ntawm 2500x1250 lossis 2400x1200. Cov neeg tsim kev paub dhau los, thaum tsim kho cov duab kos thiab teeb tsa lub ru tsev, sib sau ua ke tus qauv ua ke, coj mus rau hauv tus account qhov ntev ntawm daim ntawv xaiv OSB.
