Ua ntej koj pib xam lub cubature ntawm ntau hom boards thiab teb cov lus nug: "Puas muaj pes tsawg lub boards nyob rau hauv ib lub voos xwmfab?" - koj yuav tsum xav txog lub tswvyim ntawm "cubic meter ntawm ntoo" txhais li cas, thiab qhov kev tsim kho kev lag luam muaj dab tsi.

Ntau yam ntoo thiab lawv qhov ntau thiab tsawg

Boards yog tau los ntawm longitudinal sawing ntawm cav. Raws li txoj cai, lawv muaj qhov ntev ntawm 4 mus rau 6 meters. Qhov dav sib txawv. Cov thinnest sawv daws yuav nyob rau hauv cov chav kawm ntawv hauv ob sab phlu - mus txog ob thiab ib nrab centimeters, ces muaj ib tug shalevka board, lub thickness ntawm uas yog yeej sib npaug rau ob centimeters (tab sis tej zaum 2, 5, thiab 4, thiab 5 cm). Ntau kim - edged tsev board, qhov ntev ntawm uas yog heev standardized: qhov dav yog ib txwm siab tshaj nws ob qhov siab, thiab qhov ntev yog 4 (tsis tshua muaj 4.5) thiab 6 meters. Thicker boards yog hu ua ntoo. Rau kev yooj yim, sawn ntoo yog muag hauv qhov cub, thiab rau kev tsim kho nws yog ib qho tseem ceeb kom paub tias muaj pes tsawg boards nyob rau hauv 1 lub voos xwmfab.

Peb yuav tsis xav txog hauv ob sab phlu, vim qhov tseeb tias hom ntoo no yog siv rau kev ua haujlwm tiav thiab suav cais.

Ua ntej tshaj plawsqhov chaw tsim kho yuav xav tau ib lub rooj tsavxwm screed, uas yog ob peb zaug pheej yig dua ib qho kev txiav thiab xav tau rau formwork, ru tsev ntaub ntawv, battens, subflooring, kev tsim kho chav dej.

Qhov dav ntawm lub rooj tsavxwm tuaj yeem yog 10-15 centimeters, ntev lawv yog cov qauv lossis txiav ua ob lossis peb meters. Paub txog thaj tsam ntawm lub hauv paus yav tom ntej thiab qhov tsis sib xws ntawm shalevka, nws yog ib qho yooj yim los xam seb muaj pes tsawg boards nyob rau hauv ib lub voos xwmfab thiab pes tsawg cubic meters koj yuav tsum tau yuav rau formwork. Rau kev xam kom raug ntau dua, koj tuaj yeem siv lub laij lej online, uas nyob rau ntawm lub vev xaib ntawm cov neeg muag khoom feem ntau.

lub cubature yog dab tsi?

Yog koj teb cov lus nug ncaj qha: "Puas muaj pes tsawg lub rooj nyob hauv ib lub voos xwmfab?" - ces yuav muaj ib qho kev xaiv - ib tug cubic meter. Peb xav tau cov ntaub ntawv tshwj xeeb ntxiv. Piv txwv li, thaj chaw ntau npaum li cas tuaj yeem raug sheathed nrog ib lub voos xwmfab ntawm ib lub thickness?

Cia li conditionally xaiv qhov dav ntawm lub rooj tsavxwm - W, lub thickness - T, ntev - D. Qhov tshwm sim yuav nyob ntawm seb thickness (T). Cov qauv cheeb tsam (P) paub los ntawm tsev kawm ntawv:

P (m²)=WxL/T (1m x 1m / 0.02m=50m^2).

Yog tias peb nqa ib lub cubic meter ntawm 2 cm tuab, lawv yuav npog 50 m 2.

Qee zaum koj yuav tsum paub qhov ntev (L) ntawm tsob ntoo hauv 1 m3.

suav siv tus qauv:

L=1 m3/T x W.

Thiab thaum kawg, cov lus teb rau lo lus nug: "Puas muaj pes tsawg lub boards nyob rau hauv ib lub voos xwmfab (beams, round blanks, etc.)?". Yog hais tias lumber parameters paub,ces qhov tshwm sim tuaj yeem tau los ntawm kev siv cov mis:

K=W x T x L

Los ntawm txoj ntsiab cai no, lub cubic peev ntawm ib lub rooj tsavxwm kuj suav nrog, tab sis tsis txhob hnov qab hloov tag nrho qhov ntev rau hauv meters.

Piv txwv ntawm kev suav cov ntim ntawm edged boards

Qhov nrov tshaj plaws edged board, uas yog siv rau phab ntsa, pem teb, qab nthab, partitions, rafters thiab ntaiv. Txhua qhov loj txawm muaj nws tus kheej "lub npe": nti, plaub caug, tsib, nqaj (nws yog tam sim no paub meej tias qhov dav ntawm lub rooj tsavxwm peb tham txog).

Xaiv, piv txwv li, pes tsawg lub boards tuaj yeem nyob hauv ib nti lub voos xwmfab, paub txog nws qhov dav. Yog li, nrog qhov dav ntawm 10 cm - cov no yog 66 daim, thiab nrog qhov dav ntawm 15 cm - 44 daim. 1 cubic meter txaus 40 m2.

Ib qho piv txwv ntawm kev suav cov cubic peev ntawm ib rau-meter inch 15 cm dav:

Luas=0.15 m x 0.025 m x 6 m=0.0225 m
• 3.

Yog tias nws tsim nyog los xam qhov ntim, piv txwv li, ntawm cov plag tsev (nrog spikes), tsuas yog qhov dav ua haujlwm ntawm lub rooj tsavxwm (tsis muaj spikes) yog hloov rau hauv cov qauv. Yog hais tias ib lub tsev thaiv (ib lub rooj tsavxwm ua raws li lub cav) raug xam, ces qhov tuab yog qhia los ntawm qhov siab tshaj plaws.
