Kev Them Nqi Rau Ntau Hom Pob Zeb

Ntau tus neeg tuaj tshiab rau kev lag luam yuav pom lawv tus kheej tsis meej pem thaum nws los txog rau kev suav cov khoom siv pob zeb. Niaj hnub no, kuv tau sau cov lus qhia ntxaws ntxaws txog cov txheej txheem kev suav pob zeb, vam tias yuav pab tau cov neeg uas tab tom nrhiav nkag mus rau - lossis tam sim no ua haujlwm hauv - kev lag luam pob zeb.

Ua ntej thiab qhov tseem ceeb tshaj plaws, txhawm rau xam qhov hnyav ntawm lub pob zeb, koj yuav tsum xub paub nws qhov ceev.

Qhov ntom ntawmgraniteyog kwv yees li 2.6-3.3 g / cm³.

Qhov ntom ntawmmarbleyog kwv yees li 2.5 g / cm³.

Thaum koj paub lub pob zeb qhov ntom, tus so yog qhov yooj yim! Nws zoo li peb hnub kawm ntawv -txhua yam koj yuav tsum ua yog siv cov qauv!

Txhawm rau xam lub pob zeb qhov hnyav: muab lub pob zeb lub ntim los ntawm nws qhov ntom.

Hauv lwm lo lus: Length × Dav × Thickness × Specific Gravity=Pob zeb hnyav.

Pob zeb hnyav=Length × Dav × Thickness × Specific Gravity. Lub ntiajteb txawj nqus ntawm pob zeb kuj tseem hu ua nws qhov ntom ntom.

● Feem ntau, lub ntiajteb txawj nqus ntawm marble yog 2.5 ( ntsuas hauv tons).

● Qhov ceev los yog tshwj xeeb lub ntiajteb txawj nqus ntawm granite yog kwv yees li 2.6 mus rau 2.9 tons ib cubic meter.

Nqe ib pob zeb thaiv (Rough Pob Zeb)=Length × Dav × Qhov siab × Specific Gravity × Nqe ib Tuj. Tus nqi thauj khoom ib square Meter ntawm pob zeb=Tus nqi thauj khoom × Pob zeb hnyav (Length × Dav × Thickness × Specific Gravity) ÷ Surface Area (hauv square meters).

● Thickness xam:

1. Xam hauv Centimeters (cm):

1 centimeter (cm)=10 millimeters (mm)=0.01 meters (m)

▲ Common Granite Thicknesses: 15 hli, 19 hli, 25 hli, 30 hli, 50 hli

▲ Common Marble Thicknesses: 20 hli, 30 hli, 40 hli

▲ Common Thicknesses rau Roman Engineered Pob zeb thiab Imported Engineered Pob zeb: 12 hli, 19 hli

2. Muab xam rau hauv "Fen" (Points):

1 Fen=1/8 nti=3.2 mm (feem ntau hu ua 3 mm)

4 Fen=4/8 nti=12.8 mm (feem ntau hu ua 12 mm)

5 Fen=5/8 nti=16 mm (feem ntau hu ua 15 mm)

6 Fen=6/8 nti=19.2 hli (feem ntau hu ua 19 mm)

(Ceeb Toom: "Fen" yog ib chav ntsuas uas feem ntau siv los ntawm cov kws tshaj lij kev lag luam zeb hauv Suav teb. Cov neeg siv khoom thoob ntiaj teb tuaj yeem txhais nws li 1/8 ntawm ib nti lossis 3 hli.)

● Kev xam qhov hnyav:

1. Granite & Marble: 5 Fen (5/8 ")=4.5 kg; 6 Fen (6/8")=5 kg; 3 cm=7.5 kg

2. Roman Engineered Pob zeb: 4 Fen (4/8 ")=2.8 kg; 6 Fen (6/8")=4.4 kg

● Raws li cov qauv kev coj ua rau pob zeb kab hlau rhuav phab ntsa, pob zeb thickness feem ntau poob rau hauv peb pawg: 18mm, 25mm, thiab 30mm.

Siv peb qhov xwm txheej no ua piv txwv, cov hauv qab no qhia txog cov txheej txheem rau kev suav cov nqi khoom:

1. Cov pob zeb pob zeb (cov pob zeb ntxhib) yuav tsum tau txiav thiab ua kom tau txais txiaj ntsig zoo thiab tuab. Siv lub thickness 18mm ua piv txwv-thiab piv txwv li pom kerf (txiav qhov sib txawv) ntawm 8mm-

ib lub cubic meter ntawm qhov ntxhib thaiv tuaj yeem tawm tau 1000 ÷ (18 + 8)=38.46 square meters ntawm cov khoom tiav.

Raws li txoj cai, qhov no yog qhov teeb meem yooj yim. Muab hais tias qhov xav tau thickness * b * (hauv mm) ntawm cov txiav slabs tau teev tseg, ib tug yuav theoretical txiav * n *=1000 / * b * square meters ntawm cov khoom. Piv txwv li, yog * b * yog 50 hli, ib tug yuav theoretically txiav 1000 / 40=250 square meters.

Txawm li cas los xij:

1) Cov khoom poob vim qhov tuab ntawm cov saw hniav yuav tsum tau muab xam rau hauv; Thaum txiav *n * slabs, muaj * n * -1 piv txwv ntawm cov khoom poob sib xws rau cov hniav thickness.

2) Tus ntoo khaub lig- ntu ntawm cov blocks ntxhib tsis tshua muaj qhov zoo sib xws lossis zoo ib yam; yog li ntawd, ntxhib- txiav slabs uas ua tsis tau raws li qhov yuav tsum tau muaj thickness specifications yuav tsum muab pov tseg.

3) Cov txheej txheem tom ntej ntawm kev txiav cov slabs rau hauv qhov tseeb, cov khoom tiav ua rau poob ntxiv -xws li kev txiav cov khib nyiab los ntawm cov npoo ntxhib, cov khoom poob vim muaj cov kab nrib pleb ua rau tawg, thiab lwm yam. Cov khoom siv tiag tiag poob yog qhov tseem ceeb thiab muaj feem cuam tshuam nrog cov txheej txheem geological tshwj xeeb thiab cov yam ntxwv ntawm lub pob zeb.

Cov lus saum toj no qhia txog kev hloov pauv hloov pauv rau cov pob zeb ntxhib. Tshwj xeeb, ib lub cubic meter ntawm pob zeb ntxhib tuaj yeem tsim 38 square metres ntawm slabs nrog lub thickness ntawm 18 hli. Lwm qhov loj me ua raws tib txoj cai.

Yog tias koj lub Hoobkas cov ntaub ntawv tsim tawm poob qis dua cov qauv ntsuas no, nws qhia tau tias koj cov txheej txheem ua haujlwm yuav tsum tau hloov kho.

2. Tus nqi ntawm cov pob zeb ntxhib yog feem ntau 6,000 RMB ib lub cubic meter. Piv txwv tias qhov loj - nplai txiav tus nqi ntawm 80 RMB ib square meter, tus nqi pib ib square meter yog 6,000 ÷ 38.46=156 RMB. Tom qab ntxiv tus nqi txiav, tag nrho cov nqi nce mus rau 156 + 80=236 RMB ib square meter.

3. Txij li cov pob zeb slabs sib txawv ntawm qhov loj thiab qhov tshwj xeeb, yeej ib txwm muaj qhov teeb meem hais txog kev siv hluav taws xob txiav (feem pua ​​​​ntawm cov slab uas tuaj yeem siv tau zoo). Tus qauv siv tus nqi ntawm 90% feem ntau yog suav tias yog. Txhawm rau suav rau qhov cuam tshuam ntawm kev txiav cov khoom pov tseg thiab kev ua haujlwm tsis zoo, tus nqi hloov kho yuav tsum suav nrog 236 ÷ 90%=262 RMB ib square meter.

4.Stone manufacturers feem ntau ua rau cov nyiaj tau los ntawm 15% mus rau 30%. Yog tias cov nyiaj tau los ntawm 15% raug siv, tus neeg tsim khoom tus nqi yuav raug xam raws li 262 ÷ 85%=308 RMB. 5. Pob zeb Cov Nqi Them Nqi:

Rau 18 hli pob zeb, tus nqi thauj khoom yog 8-10 RMB / m²;

rau 25 hli pob zeb, nws yog 14-16 RMB / m²;

thiab rau 30 hli pob zeb, nws yog 18-23 RMB / m².

Tag nrho cov nuj nqis xav tias ib qho kev thauj khoom thiab kev thauj mus los; tus nqi tshwj xeeb tau xaiv (hauv qhov muab ntau) nyob ntawm qhov kev ncua deb ntawm qhov project site thiab qhov chaw ua haujlwm.

Piv txwv li, tus nqi rau 25 hli pob zeb yog xam raws li nram no: 1000 ÷ (25 + 8)=30.30 m²; 6000 ÷ 30.30=198 RMB/m²;

198 + 80=278 RMB/m²; 278 ÷ 90%=309 RMB/m²; 309 ÷ 85%=363 RMB/m². Tom qab tus nqi thauj mus los: 363 + 14=377 RMB/m².

Piv txwv li, tus nqi rau 30 hli pob zeb yog xam raws li nram no: 1000 ÷ (30 + 8)=26.31 m²; 6000 ÷ 26.31=228 RMB/m²;

228 + 80=308 RMB/m²; 308 ÷ 90%=342 RMB/m²; 342 ÷ 85%=402 RMB/m².

Tom qab suav cov nqi thauj mus los: 402 + 18=420 RMB/m².

Tswv yim

Tsab ntawv xov xwm no qhia txog cov nqi ua pob zeb hauv Suav teb, nrog cov lej suav nrog RMB. Raws li tus nqi pauv hloov pauv mus tas li, cov neeg nyeem thoob ntiaj teb tuaj yeem siv qhov piv txwv yooj yim ntawm 1: 7 raws li kev siv ntxhib rau kev kwv yees tus nqi.

Piv txwv li, yog tias tus nqi ntawm 30 hli pob zeb yog 228 RMB ib square meter, qhov no tuaj yeem xam tau yooj yim li 228 ÷ 7=32.57.

Hauv lwm lo lus, tus nqi ntawm 30 hli pob zeb yog kwv yees li $ 32.57 ib square meter.

Cov qeb ntawm pob zeb kab yog qhov dav heev, suav nrog ntau yam duab thiab qauv; yog li ntawd, tsis muaj ib qho qauv uas tso cai rau tus nqi ncaj qha, tus qauv qauv hais. Hauv paus, tus nqi tsev yog xam raws li: Chav Tsev Nqe=Tus Nqi + Cov Nyiaj Tau Los=Cov Khoom Siv + Tus Nqi Ua Haujlwm + Cov Nyiaj Tau Los.

1. Cov nqi ntawm cov khoom siv kuj yooj yim los xam. Txawm li cas los xij, cov nqi ua haujlwm sib txawv heev vim muaj cov yam ntxwv xws li qhov nyuaj thiab nyuaj ntawm kab tsim, hom tshwj xeeb ntawm cov khoom siv pob zeb siv, thiab cov cuab yeej sib txawv, kev ua tau zoo, thiab kev txawj tshwj xeeb ntawm cov neeg tsim khoom. Yog li ntawd, nws yog tsis yooj yim sua kom muab tau ib qho, meej lej suav rau kev ua cov nqi.

2. Rau cov qauv, cov pob zeb yooj yim, kev suav yuav tshwm sim ncaj nraim ntawm qhov chaw; Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas qhov tshwj xeeb qhov ntev thiab cov qauv pob zeb (veining) thov los ntawm tus neeg siv khoom. Txij li cov pob zeb feem ntau xav tau cov khoom siv ntev ntev, nrhiav cov pob zeb nyoos (cov pob zeb zeb zeb) uas ua tau raws li qhov yuav tsum tau muaj qhov ntev yuav nyuaj. Yog li ntawd, tus nqi kawg tsis tau txiav txim siab raws li tus qauv kev lag luam tus nqi rau cov slabs lossis cov blocks raw, tab sis tau soj ntsuam raws li qhov tshwj xeeb yuav tsum tau ua - feem ntau yuav tsum tau siv cov kev cai - xaj cov blocks.

3. Yog li ntawd, txoj hauv kev zoo tshaj plaws rau tus nqi yog muaj kev paub ncaj qha hauv kev ua pob zeb; tsuas yog los ntawm kev sib sau ua ke ntawm qhov ntev - lub sijhawm ua haujlwm tau zoo tuaj yeem ua tiav qhov kev kwv yees tus nqi tsim nyog.

Feem ntau, cov kws ua haujlwm paub txog thiab cov kws ntsuas ntsuas siv cov qauv qhia pom tseeb- tau los ntawm kev ua tau zoo- los ua cov kev suav no. Piv txwv li, ib lub tuam txhab ib zaug commissioned ib batch ntawm txhua kab uas nthuav qhia cov kev sib tw tseem ceeb. Lub chaw tsim khoom, tso siab rau nws qhov kev paub dhau los, tau muab qhov kev kwv yees thawj zaug. (Lub chaw tshwj xeeb no tshwj xeeb hauv kev tsis xwm yeem- cov khoom lag luam pob zeb thiab kab, khav tshaj kaum xyoo ntawm kev paub hauv thaj chaw.)

Txawm li cas los xij, thaum lub sijhawm tsim khoom tiag tiag, qhov teeb meem kev ua haujlwm tau ua pov thawj ntau dua li qhov xav tau, ua rau 50% nce ntawm cov nqi tsim khoom tiag tiag (raws li lees paub los ntawm lub Hoobkas nws tus kheej). Txawm li cas los xij, vim tias qhov tsis sib xws tau tshwm sim los ntawm lub Hoobkas tus kheej kev suav tsis raug thaum lub sijhawm kwv yees, tus nqi muag zaum kawg raug them rau tus neeg siv khoom tseem tsis hloov pauv ntawm cov lus qub.

Cov saum toj no ua haujlwm luv luv thiab sib qhia ntawm qee cov qauv siv hauv pob zeb pricing. Raws li kev ua lag luam thiab cov nqi ua lag luam hloov zuj zus, tus nqi tiag tiag yuav txawv me ntsis ntawm cov lus qhia dav dav. Cov ntaub ntawv no yog muab rau koj siv. Ua tsaug rau koj qhov kev txhawb nqa txuas ntxiv mus. Cheefung tuam txhab tshwj xeeb hauv R & D thiab tsim cov cuab yeej sib tsoo thiab polishing rau cov khoom siv pob zeb ntuj thiab cov khoom siv pob zeb-xws li cov slabs loj, sawb slabs, thiab tsis sib xws - cov khoom siv pob zeb.
