Ua ntej pib tsim lub tsev, nws yog qhov tsim nyog los kos nws qhov kev kwv yees tsim. Cov ntaub ntawv no qhia ntau npaum li cas cov ntaub ntawv xav tau rau kev ua haujlwm, nrog rau lawv cov nqi. Yog hais tias cov lus nug tshwm sim ntawm yuav ua li cas xam lub cubic muaj peev xwm ntawm lub rooj tsavxwm, tom qab nyeem tsab xov xwm no, koj yuav tau txais ib lo lus teb rau nws.
Lumber: ntau yam thiab suav nta
Cov khoom lag luam zoo thiab cov khoom lag luam raug cuam tshuam los ntawm hom ntoo thiab cov txheej txheem ntawm kev tsim cov khoom siv hauv tsev. Muaj ob hom boards:
- Edged - hwm ntoo uas muaj qhov tseeb.
- Unedged - cov khoom ntoo, sab ntug uas tsis ua tiav, yog li lawv muaj cov tawv ntoo. Cov neeg tsim khoom siv cov boards zoo li no rau kev tsim kho cov flooring ntxhib thiab qab nthab. Lawv qhov txiaj ntsig tseem ceeb yog lawv cov nqi qis piv rau cov ntoo ntoo.
Ua ntej koj xam lub cubature ntawm lub rooj tsavxwm, koj yuav tsum txiav txim siab seb yam khoom twg yuav raug siv los tsim ib qho chaw ntawm lub tsev (piv txwv li, pem teb). Nws yog qhov yooj yim dua kom paub qhov ntim ntawm edged boards vim lawv cov duab raug. Yog hais tias nws yog tsim nyog los xam lub cubic muaj peev xwm ntawm finishing qhov chaw (hauv ob sab phlu los yog ntoo), ces nyob rau hauv cov ntaub ntawv no tsuas yog qhov ntev ntawm lub ntsiab ntawm cov khoom yuav tsum tau muab coj mus rau hauv tus account, uas yog, qhov ntev ntawm tshwj xeeb tav thiab grooves yuav tsis. coj mus rau hauv tus account.
Txhawm rau txiav txim siab tus naj npawb ntawm cov laug cam hauv lub voos xwmfab, cov kws ua haujlwm siv cov mis tshwj xeeb, thiab cov ntoo uas tsis muaj ntoo yuav tsum tau suav qhov txawv me ntsis, vim tias cov khoom ntoo zoo li no tsis muaj npoo meej.
Formula rau xam edged boards
Txhawm rau txiav txim siab lub peev xwm ntawm cov khoom lag luam, koj yuav tsum paub qhov ntev ntawm cov ntsuas hauv qab no:
- length;
- dav;
- siab.
Yog tias qhov ntev yog paub, ces lawv yuav tsum muab sib npaug nrog ib leeg siv cov qauv tshwj xeeb uas zoo li no:
V=L x b x h where:
- L yog qhov ntev ntawm ib lub rooj tsavxwm hauv meters;
- b - khoom dav;
- h - edged board qhov siab.
Siv cov qauv no, koj tuaj yeem pom qhov ntim ntawm ib feem tau yooj yim. Txawm li cas los xij, ua ntej xam qhov cubature ntawm lub rooj tsav xwm edged, millimeters yuav tsum tau hloov mus rau meters, yog tias tsim nyog. Yog hais tias qhov ntev ntawm ib feem yog 3000 x 150 x 22, ces txhua qhov ntsuas yuav tsum tau pib muab faib los ntawm 0.001, thiab tom qab ntawd cov qauv yuav tsum tau muab los, uas qhov no yuav zoo li qhov no:
V=3 x 0, 15 x 0, 022
Yog li ntawd, nws hloov tawm tias ib lub rooj tsavxwm muaj qhov ntim sib npaug li 0.0099 m 3 (cubic meters). Tom qab ntawd, koj yuav tsum paub seb muaj pes tsawg unitscov khoom yog khaws cia rau hauv ib lub cubic meter. Ua li no, cov neeg tsim khoom siv cov qauv lej, uas yuav tsum tau siv los faib 1 m 3rau hauv qhov tshwm sim ntawm ib qho khoom ntoo. Kev suav yuav zoo li no:
1 / 0, 0099=101, 01 m³
Yog lo lus nug tshwm sim, yuav ua li cas xam lub cubature ntawm lub edged board, ces thaum kawg nws hloov tawm hais tias 1 m 3 muaj 101 units (tus nqi yuav tsum muab sib npaug tawm) ntawm cov khoom ntoo, qhov ntev ntawm qhov uas tau qhia yav dhau los. Tom ntej no, koj tsuas yog yuav tsum tau txiav txim siab tus naj npawb ntawm cov ntoo uas xav tau rau kev tsim kho lub tsev. Cov neeg tsim khoom paub txog pom zoo kom yuav cov khoom nrog qee cov npoo, vim tias thaum lub sij hawm tsim kho, qee cov khoom yuav deteriorate vim kev puas tsuaj.
Xaiv cov boards tsis muaj boards
Cov duab ntawm cov khoom tau hais muaj qhov tsis raug, vim tias cov ntoo no tsis muaj cov duab plaub. Unedged boards feem ntau yog siv rau kev tsim kho vaj tse ib ntus lossis cov plag tsev ntxhib.
Cov neeg tsim khoom siv ntau txoj hauv kev los txiav txim seb muaj pes tsawg qhov hauv ib lub cubic meter. Txawm li cas los xij, cov ntsuas no yog qhov nyuaj rau kev tsim, vim nws nyuaj rau kev xam cov khoom lag luam uas muaj cov duab tsis zoo. Ua ntej xam lub cubature ntawm lub rooj tsavxwm unedged, koj yuav tsum xav txog nyob rau hauv ntau nthuav dav txhua txoj kev thiaj li yuav xaiv qhov yooj yim tshaj plaws. Muaj ntau txoj hauv kev:
- Batch.
- Piece method.
- Sampling method.
Hauv thawj txoj kev, cov laug cam yuav tsum muab tso rau hauv ib lub hnab thiabntsuas cov ntaub ntawv xav tau. Cov kauj ruam tom ntej yog txiav txim siab qhov ntim siv cov ntsuas uas tau txais thaum ntsuas ntsuas. Yog hais tias cov lus nug tshwm sim, yuav ua li cas xam lub cubature ntawm lub rooj tsavxwm nyob rau hauv pem teb (draft), ces qhov kev xaiv no muab ib tug meej cov lus teb rau nws, tab sis qhov no tsis yog txoj kev ceev tshaj plaws.
Thaum siv cov txheej txheem, koj yuav tsum tau siv cov lej (hauv metres), uas yuav tsum tau muab coj los rau hauv tus account qhov siab thiab qhov dav ntawm lub rooj tsavxwm unedged. Txhawm rau xam qhov nruab nrab, koj yuav tsum xub ntsuas qhov tsawg kawg nkaus qhov dav ntawm cov khoom, thiab tom qab ntawd qhov siab tshaj plaws. Tom qab ntawd, ntxiv ob tus lej thiab faib los ntawm 2. Ib yam nkaus, koj yuav tsum xam qhov nruab nrab qhov siab ntawm lub rooj tsavxwm. Cov kauj ruam kawg yog muab cov ntaub ntawv tau txais los ntawm qhov ntev ntawm ntu.
Cov qauv qauv yog siv los ntawm cov neeg tsim khoom yog tias nws tsim nyog los xam cov cubic peev ntawm cov ntoo loj. Qhov tseem ceeb ntawm txoj kev no yog dab tsi? Koj yuav tsum tau coj ob peb lub rooj tsavxwm, thiab tom qab ntawd xam lawv tib yam li hauv batch version. Cov nuj nqis uas tau txais yuav tsuas yog muab faib los ntawm tag nrho cov khoom hauv pawg.
Nyob hauv kaw
Lumber tej zaum yuav xav tau nyob rau hauv ib qho kev tsim kho, yog li nws yog ib qho tseem ceeb uas yuav tau yuav lawv raws li qhov xav tau kom muaj kev nyab xeeb ntawm kev tsim khoom. Txawm li cas los xij, rau qhov no koj yuav tsum muaj peev xwm xam qhov ntim ntawm cov khoom, yog li cov khoom piav qhia yuav ua li cas xam lub cubature ntawm lub rooj tsavxwm ntawm ob hom: edged thiab unedged.
