Ua ntej koj pib tsim lub tsev ntoo, koj yuav tsum txiav txim siab txog cov khoom siv thiab nkag siab txog qhov yuav tsum tau ua kom tau txais txiaj ntsig zoo. Feem ntau, hom ntoo coniferous yog siv rau kev tsim cov ntoo, ntawm lawv nws yog qhov tsim nyog qhia:

  • larch;
  • cedar;
  • pine;
  • spruce;
  • fir.

Hauv cov ntim me me nws yog tsim los ntawm cov ntoo tawv, uas yog:

  • aspens;
  • birch ntoo;
  • oak.

Qhov ntev ntawm lub nqaj ntoo tuaj yeem sib txawv heev, tab sis qhov ntsuas ntsuas yog qhov ntev thiab ntu. Ntawm lwm cov yam ntxwv, cov txheej txheem ntawm kev ua haujlwm yuav tsum tau qhia. Lub nqaj raws li qhov ntsuas no tau muab faib ua kev npaj thiab tsis npaj. Cov yav tas yog siv qhov chaw nto tsis tseem ceeb. Nyob ntawm seb qhov seem yog dab tsi, cov khoom siv yuav raug hu ua bar. Hauv qhov no, lub thickness tsis tshaj 100 hli.

Pem hauv ntej ntawm koj yog ib qho bar yogloj los ntawm 100 mm thiab ntau dua. Qhov ntau ntawm qhov ntev thiab ntu ntu tsis yog qhov dav tshaj plaws rau hom ntoo no, thiab nws tsuas yog txwv los ntawm qhov ntev ntawm cov khoom siv raw. Xav txog qhov ntev ntawm lub nqaj ntoo, nws tuaj yeem raug sau tseg tias cov khoom siv los ntawm cov array feem ntau muaj ntu ntu txog li 250 hli. Yog tias cov khoom loj dua, cov neeg tsim khoom sim ua raws li tus neeg txiav txim thiab rau qee lub hom phiaj.

Cov nqaj no muaj qhov txhawb nqa, ua ke ua ke los ntawm kev hloov cov fibers ntawm lub rooj tsavxwm. Cov khoom yog tus cwj pwm los ntawm lub zog siab hauv qhov no. Lwm qhov zoo dua hauv qhov no yog cov ntoo laminated yuav luag tsis ntsws, vim nws yog tsim los ntawm cov ntoo zoo qhuav. Thaum xaiv qhov ntev ntawm cov nplaum laminated ntoo, koj tuaj yeem paub tseeb tias qhov ntsuas yuav tsis hloov pauv. Qhov luaj li cas ntawm cov ntoo beam nyob rau hauv cov ntaub ntawv no muaj rau xaiv los ntawm. Txoj kev hla yuav txawv heev, uas yog: 150; 210 los yog 270 mm. Thickness yog cov neeg siv xaiv. Nws tsis tsim nyog tsis tsim nyog nce nws, vim tias qhov no tuaj yeem cuam tshuam tus nqi ntawm kev tsim kho, txij li tus nqi ntawm cov khoom yog siab tshaj. Koj yuav tsum sim nrhiav qhov sib npaug ntawm cov tuab thiab cov khoom siv.

Xav txog qhov ntev ntawm cov nqaj ntoo, koj tuaj yeem nco ntsoov tias cov khoom tuaj yeem muaj cov duab plaub thiab tsim nyob ntawm lub hom phiaj. Cov khoom siv phab ntsa, piv txwv li, tuaj yeem muaj qhov ntsuas ntawm 140 x 160 txog 170 x 280 mm. Pem teb kab teeb tuaj yeem muaj qhov siab ntawm 85 txog 1120 hli. Lawv qhov siab tshaj plaws yog 260 mm, cesraws li qhov tsawg kawg nkaus tus nqi yog 95 mm. Nws tseem yuav tsum tau hais txog tus qauv qhov ntev ntawm lub nqaj ntoo, yog tias lub lumber hu ua qhov rais lumber. Cov kev ntsuas feem ntau yog: 82 x 86 thiab 82 x 115 mm.

Cov ntoo no yog ua los ntawm cov ntoo thiab tuaj yeem muaj qhov sib txawv geometry, uas yog:

  • ob;
  • Finnish;
  • Nyob zoo ib tsoom phooj ywg.

Yog tias koj tsim lub tsev los ntawm cov ntoo ntoo, nws yuav tsis xav tau kev ua haujlwm tiav, ntxiv rau, nws yuav zoo tiv thaiv los ntawm ya raws thiab txias. Tom qab tshuaj xyuas cov duab ntawm ib lub nqaj ntoo, koj tuaj yeem nkag siab tias cov khoom siv no zoo li zoo nkauj heev. Nws qhov ntev yog nthuav tawm nyob rau hauv tus qauv ntau ntawm 100 x 100 txog 200 x 200 mm.

Lub hom phiaj ntawm lub nqaj txiav txim siab nws qhov tuab. Yog hais tias tus nqi no yog 100 hli, ces koj muaj ib tug sib sib zog nqus khoom uas mus rau kev tsim kho ntawm gazebos, outbuildings thiab verandas. Xws li ib tug profile copes zoo nrog cov loads uas tig los ua cov qauv ntawm lub teb chaws lub tsev. Nws yuav siv tau lub tsev nyob rau lub caij ntuj sov.

Yog tias koj nyob hauv ib cheeb tsam uas muaj huab cua me me, ces 150 hli beam zoo meej rau koj. Xws li ib qho profile yuav tiv thaiv cov txheej txheem kaw los ntawm khov. Rau kev tsim kho ntawm lub tsev, feem ntau yog siv lub beam ntawm 200 mm thickness. Cov khoom siv zoo li no kim dua, tab sis nws cov khoom siv thermal ua rau nws muaj peev xwm tsim cov cav cabins uas tsis muaj cov thermal rwb thaiv tsev ntxiv. Rau qhov noprofiled ntoo yog siv nrog qhov ntev sib npaug 200 x 150 lossis 200 x 200 mm.

Qhov ntev ntawm cov ntoo bar raws li GOST tau txiav txim siab txog qhov ntev, uas nyob hauv thaj tsam ntawm 3 mus rau 9 m. Qhov ntev ntawm lub ntsiab yog los ntawm 300 txog 600 cm. Cov kev ntsuas no yog qhov zoo tshaj plaws rau khaws cia, kev thauj mus los thiab kev tsim kho. Qee zaum, cov ntoo yog tsim rau ib tus neeg qhov ntau thiab tsawg thiab muaj qhov ntev tshaj plaws. Qhov no feem ntau yog hais txog cov qauv txheej txheem ntoo ntoo.

Rau cov ntoo los ntawm ntau hom ntoo, nws tus kheej lub xeev tus qauv tau txhais. Piv txwv li, cov ntaub ntawv softwood yuav tsum ua raws li GOST 8486-86. Hardwood lumber parameters yog tswj los ntawm GOST 2695-83.

Thaum tsim lub ru tsev ntawm cov tsev ntiag tug, cov laug cam yog siv. Lawv qhov hla yuav tsum yog 50 x 150 mm. Xws li lumber tsis yog haum rau ru tsev ntawm ntau yam designs. Qhov kev ncua deb ntawm cov ceg rafter yog kwv yees li ntawm ib meter. Cov kauj ruam no nyob ntawm hom vov tsev, cov daus thaum lub caij ntuj no thiab txoj kab nqes ntawm lub ru tsev.

Qhov ntev ntawm cov nqaj ntoo rau cov rafters tseem ceeb npaum li cov kauj ruam ntawm lawv. Yog tias lub ru tsev txoj kab nqes ntau tshaj 45˚, ces qhov kev ncua deb ntawm cov khoom tuaj yeem ncav cuag 1.4 m. Qhov dav ntawm cov khoom rau cov rafters yog xaiv raws li qhov ntev ntawm qhov qhib yuav tsum tau thaiv. Nrog rau qhov ntev ntawm lub rafter ceg, qhov dav ntawm lub rooj tsavxwm nce.

Yog tias koj xav tau 6 m rafter, nws yog tsim los ntawm 150 hli board. Qhov tsawg kawg nkaus tus nqi hauv qhov no yog 50 x 150 mm. Yog tias txhais ceg ntev dua 6 m, qhov dav yuav tsum yog tsawg kawg 180 mm. Cov ceg txuas ntxiv yog tsim los ntawm 150mm cohesive planks. Qhov chaw sib tshooj yuav tsum nyob ze li qhov ua tau mus rau qhov ntu ntu. Qhov hla ntawm cov rafters yuav nyob ntawm qhov load ntawm lub ru tsev, nrog rau cov cua load, nrog rau qhov hnyav ntawm lub truss qauv, qhov ntev ntawm lub overlapped qhib, lub kaum sab xis ntawm inclination ntawm txoj kab nqes thiab qhov dav ntawm lub ru tsev. tsev.

Qhov ntev ntawm kab rau lub cav ntawm lub hauv paus ntoo yog xaiv tus kheej. Qhov kev ntseeg ntawm tus qauv tsim yuav nyob ntawm qhov no. Nrog rau qhov ntev ntawm lub lag luam feem ntau tsis muaj teeb meem. Qhov kev ntsuas no nyob ntawm qhov kev taw qhia tso thiab feem ntau sib npaug rau qhov dav lossis qhov ntev ntawm chav. Qhov kev xaiv zoo tshaj plaws yog qhov ntev ntawm cov ntoo 3 cm tsawg dua qhov kev ncua deb.

Qhov lag luam yog xam raws li qhov ua tau ntawm qhov chaw thau khoom thiab qhov luaj li cas ntawm qhov nruab nrab ntawm cov ntsiab lus txhawb nqa. Feem ntau lees txais tus nqi thauj khoom yog 300 kg / m 2. Qhov kev xaiv no yog qhov zoo rau thaj chaw nyob. Piv txwv li, yog tias qhov ncua sij hawm yog 2 m, ces qhov lag luam yog 110 x 60 mm. Tus nqi siab tshaj plaws yog 220 x 180 mm, uas yog qhov tseeb rau qhov ntev ntawm 6 meters.

Ntau yam ntoo ua ntaub ntawv

Boards tuaj yeem txiav thiab tsis txiav, tab sis qhov ntsuas ntawm cov ntaub ntawv yog ntsuas los ntawm cov npoo. Lub bar tuaj yeem yog 2-, 3- lossis 4-edged. Thawj ob sab yog cav sib npaug. Ob qhov sib txawv yog ua tiav. Peb-edged beam muajpeb kho qhov chaw, tom kawg yog nyob rau hauv nws tus thawj lub xeev. Plaub-sab ntoo yog ua tiav los ntawm txhua sab thiab yog qhov kim tshaj plaws ntawm nws hom ntawm lub khw.

Cov khoom siv niaj hnub tau nyab lub khw. Tab sis qhov zoo qub ntoo nqaj, uas tseem siv rau kev tsim kho rau niaj hnub no, tsis poob nws qhov tseeb. Qhov no yog vim lub fact tias nws muaj durability, kev cia siab rau thiab ib tug unrivaled saib. Thaum pib, lub nqaj yog ib lub cav uas tau npaj kom tau txais ib ntu. Niaj hnub no, ntoo yog ib yam khoom uas muaj peev xwm tsis tsuas yog ntawm ib tug array, tab sis kuj ntawm glued khaubncaws sab nraud povtseg, mix sawdust, uas muaj ib tug nplaum muaj pes tsawg leeg yog ntxiv.
