Thaum tsim ib lub rooj cob qhia, thawj qhov kev txiav txim siab feem ntau tsis xaiv tus neeg cog lus - nws yog xaiv cov qauv: portal thav duab lossis pob zeb thav duab?
Cov tswv feem ntau piv tsuas yog ib tus lej: tus nqi ib square meter. Qhov ntawd yog qhov tseeb qhov kev txiav txim siab tsis ncaj ncees pib. Tus nqi yog qhov tshwm sim, tsis yog qhov ua rau. Txoj kab sib faib tiag tiag yog ncua sij hawm, kev tsim kho, thiab yuav hloov li cas rau tsib xyoos tom ntej.
Kab lus no siv cov ntaub ntawv thiab cov haujlwm tiag tiag los daws cov lus nug ib zaug thiab rau tag nrho.
Qhov Zoo Tshaj Plaws ntawm Cov Txheej Txheem Hlau: Span txiav txim siab txhua yam
Span: 24 Meters Yog Txoj Kev Sib Tw
Hauv qab 24-meter ncua, ob qho tib si cov qauv ua haujlwm, thiab kev sib piv cov nqi ua rau muaj kev nkag siab zoo. Thaum qhov kev ncua deb tshaj 30 meters, pob zeb tus nqi kom zoo dua sai sai ploj.
Cov ntaub ntawv kev lag luam yog ncaj nraim:
| Sib piv Dimension | Portal Ncej (Steel) | Qhob Ncej |
| Economic kev ncua | 15-50 m | 8-12 m kab kab |
| Tshaj li 18 m | Tus nqi nce maj mam | Tus nqi overtakes steel |
| Kem-dawb qhov chaw | Tsis muaj kab sab hauv ntawm cov spans loj | Kem txhua 6-12 m |
| Zoo tshaj plaws rau | Rhiav / warehousing / logistics | Ntau-storey heavy-load vaj tsev |
Qhov chaw tsis muaj kab ke txhais li cas? Racking tuaj yeem mus txhua qhov chaw, cranes tuaj yeem khiav txhua qhov chaw, thiab cov kab ntau lawm tuaj yeem rov kho dua txhua lub sijhawm. Rau logistics, warehouses, thiab niaj hnub manufacturing, uas yog nyiaj.
Lub Sijhawm Tsim Kho: Dab tsi 30% -50% Ceev dua txhais tau tias
Rau kev cob qhia ntawm tib qhov loj, steel qauv yog 30% -50% nrawm dua li pob zeb.
Daim ntawv qhia siv:
| Kev tsim kho theem | Steel Qauv | Qhob Ncej |
| Foundation ua haujlwm | 7-14 hnub | 14-28 hnub |
| Main qauv | 10-20 hnub (lub Hoobkas prefab + hoisting) | 40-60 hnub (formwork / pouring / curing) |
| Lub hnab ntawv system | 10-15 hnub | 20-30 hnub |
| Tag nrho lub sijhawm | Kwv yees li. 30-50 hnub | Kwv yees li. 80-120 hnub |
Vim li cas cov hlau nrawm dua: tag nrho cov khoom yog prefabricated nyob rau hauv lub Hoobkas, thiab qhov chaw yog "qhuav ua hauj lwm" - hoisting thiab bolting, tsis muaj tos rau kev kho pob zeb. Thaum lub hauv paus tau tsim, cov khoom twb tau tsim nyob rau hauv lub Hoobkas tib lub sijhawm.
Pib ntau lawm ib hlis ua ntej txhais tau hais tias ib lub hlis ntawm cov nyiaj ntsuab ntws. Rau cov haujlwm hauv qab them rov qab lossis nqi xauj tsev, qhov sib txawv ntawm lub sijhawm muaj nqis ntau dua li tus nqi ib-square-meter sib txawv.
Tus nqi zais: Peb tus account uas yooj yim rau nco
Lub Foundation Tus Nqi Them Nyiaj
Cov qauv hlau hnyav tsuas yog ib feem peb mus rau ib feem tsib ntawm ib qho pob zeb. Qhov hnyav dua txhais tau tias cov hauv paus me me - cov nqi hauv paus tuaj yeem txiav los ntawm kwv yees li 30%. Hauv thaj chaw mos-av, qhov zoo dua no loj dua.
Tus Nqi Residual Account
- Hlau: 30% -40% recyclability - ib qho cuab tam thaum kawg ntawm lub neej
- Qhob: demolition raug nqi nyiaj los tshem tawm - lub luag haujlwm
Lub Expansion & Retrofit Account
Kev lag luam hloov txhua ob peb xyoos; lub rooj cob qhia yuav tsum ua raws li:
| Retrofit xav tau | Steel Qauv | Pob zeb |
| Extend span / ntxiv bay | Bolted kev twb kev txuas - kev npaj ua haujlwm | Demolishing phab ntsa ≈ rebuilding |
| Ntxiv nyiaj siv ua haujlwm crane | Tsuas yog pre-set corbels | Txhim kho kab teeb & kab; yuav tsum tau nres ntau lawm |
| Ntxiv mezzanine | Ua tau | Pem teb slab load tsis txaus |
Thaum twg Koj Tseem Yuav Xaiv Cov Khoom Siv?
Ib tus neeg muab khoom ncaj ncees yuav qhia rau koj rau sab nraud. Pob zeb yog qhov zoo dua nyob rau hauv cov xwm txheej no:
- Multi-storey heavy-load rhiav saum 4 storeys
- Muaj zog corrosive ib puag ncig (kev cob qhia tshuaj lom neeg / electroplating) qhov tshwj xeeb tiv thaiv corrosion tsis xav tau
- Cov kev cai tiv thaiv hluav taws kub heev nrog kev lees txais lub sijhawm ntev dua
Kev xaiv txoj cai: thawj zaug txiav txim siab qhov ncua sij hawm thiab qhov kev xav tau yuav hloov li cas hauv 5 xyoos tom ntej, tom qab ntawd tham txog tus nqi ib square meter. Tau txais qhov kev txiav txim tsis raug, thiab txhua yam hauv qab dej mus yuam kev.

Cov khoom lag luam suav nrog kev cob qhia kev lag luam, kev xa khoom thauj khoom, chaw thau khoom loj, kev sib tw conveyor, thiab EPC kev cog lus dav dav - thiab BESTA tau nkag mus rau cov saw hlau ntawm ntau lub tuam txhab Fortune Global 500.
FAQ
Q1: Ntau npaum li cas steel qauv rhiav ib square meter?
A: Nws nyob ntawm qhov ntev, qhov siab ntawm qhov siab, lub peev xwm crane, thiab cov qauv cladding. Qhov loj dua qhov ntev thiab qhov siab dua qhov kev teeb tsa, qhov siab dua cov nqi tsev. Qhia koj qhov ncua sij hawm thiab npaj siv, thiab peb yuav muab cov lus pom zoo sib piv.
Q2: Dab tsi yog qhov siab tshaj plaws ntawm lub portal ncej?
A: Kev lag luam ncua sij hawm yog 15-50 m. Rau qhov loj dua, peb pom zoo kom hloov mus rau truss lossis qhov chaw thav duab - BESTA tau xa cov haujlwm loj nrog qhov ntev txog 185 m.
Q3: Koj puas ua haujlwm rau cov haujlwm txawv teb chaws?
A: Yog. Peb muab tag nrho cov saw hlau tsim-fabrication-logistics-installation cov kev pabcuam, thiab tseem txhawb nqa "Suav kev taw qhia + cov neeg ua haujlwm hauv zos" qauv.
Q4: Lub rooj cob qhia steel siv sijhawm ntev npaum li cas?
A: Lub neej kev pab tsim yog 50 xyoo. Cov txheej tiv thaiv corrosion xav tau kev tshuaj xyuas thiab tu txhua 15-20 xyoo; nrog kev saib xyuas ib txwm muaj, lub neej kev ua haujlwm tsis raug cuam tshuam.
Q5: Cov lej twg yog siv rau cov haujlwm xa tawm?
A: Tsim thiab hloov dua siab tshiab tuaj yeem ua raws EN / GB thiab lwm cov lej thoob ntiaj teb; peb muaj kev paub dhau los hauv cov khoom sib npaug (piv txwv li, Q355B vs. S355JR).
