Ib tsob nroj steel qauv uas tau ua haujlwm tau kaum xyoo txiav txim siab ntxiv hnub ci. Thawj qhov teeb meem yog dab tsi?
Tsis xaiv modules. Tsis sib tham tus nqi hluav taws xob. Nws yog qhov kev ntsuam xyuas tus qauv.
Qhov kev ntsuam xyuas feem ntau xaus: purlins yog undersized, lub ntsiab beams yog marginal - hnub ci yog ua tau, tab sis tsuas yog tom qab ntxiv dag zog. Tus tswv tom qab ntawd pom tias qhov project txhais tau tias txuag hluav taws xob ua ntej raug nqi nyiaj rau kev ntxiv dag zog thiab txawm tias cov khoom lag luam poob qis.
Cov nyiaj ntawd tsis tas yuav siv. Muaj qhov sib txawv raws nraim: seb lub hnub ci thauj khoom puas suav nrog thaum tsim qauv, lossis ntxiv tom qab tom qab lub tsev tiav. Kab lus no siv cov ntaub ntawv los teeb tsa tus nqi sib txawv ntawm ob txoj kev.
Rooftop Solar's First Hurdle: Cov Qauv Loads
Qhov Ntxiv Hnub Ci Load: Ib Tus Naj Npawb, Lub Siab Tsis Txaus
Qhov ntxiv load ntawm faib (ru tsev) hnub ci yog feem ntau nyob rau hauv thaj tsam ntawm 15-25 kg ib square meter. Nws suab me me. Tab sis nws yog ib tug tuag load - nias ntawm purlins thiab lub ntsiab beams 24 teev nyob rau hauv ib hnub, tsis clocking tawm.
| Load Hom | Magnitude | Duration | Kev xav tau ntawm tus qauv |
| Tus kheej qhov hnyav ntawm lub hnub ci system (modules + txhawb nqa + cables) | 15-25 kg/m² | Tuag load, 24 teev | Purlins thiab cov kab teeb tseem ceeb yuav tsum tau kuaj xyuas dua |
| Kev tu cov load | Raws li tus nqi code | Sib nrug | Kev tu txoj kev taug kev yuav tsum tau tseg |
| Cua load (module windward ntsej muag) | Nce nrog cheeb tsam | Nruam ncov | Tshawb xyuas kev sib txuas uplift resistance |
Tsab Cai rau Retrofitting thiab Strengthening
Rau hnub ci retrofits ntawm cov nroj tsuag uas twb muaj lawm, ib qho kev ntxiv dag zog rau kev ua haujlwm thiab nws cov nqi Cheebtsam:
| Retrofit Tus nqi khoom | Kev piav qhia | Magnitude |
| Kev ntsuam xyuas tus qauv + kev tsim kom muaj zog | Kev tshuaj xyuas thiab kev siv zog ntxiv | Tus nqi ib zaug |
| Ntxiv purlins los yog hloov lawv tag nrho | Qhov feem ntau siv zog ntsuas | Khoom siv + kev ua haujlwm |
| Ib nrab ntau lawm nres rau kev ua haujlwm | Ru tsev ua haujlwm cuam tshuam ntau lawm | Indirect nqi |
| Ru tsev tshem tawm / reinstallation thiab rov kho dua | Txhim kho kev tiv thaiv tom qab kev cuam tshuam | Feem ntau overlooked |
Ua ke, cov no feem ntau noj 15% -25% ntawm cov peev nyiaj rov qab.
Nrog rau kev tsim qauv, los ntawm qhov sib txawv: loads, module layout, cable routing thiab txij nkawm nkag mus rau tag nrho cov mus rau hauv lub drawings ntawm lub tsim theem. Kev siv hlau tsuas yog nce me ntsis, thiab tus nqi ntxiv dag zog yog xoom.
Integrated Design: Peb kauj ruam, xam ib zaug
Tus Qauv Tsim thiab Solar Engineers ntawm Same Drawing Board
| Kev Sib Koom Tes | daws teeb meem | Qhov tshwm sim ntawm Kev Cai Ob-Phase Design |
| Purlin spacing muab tau los ntawm qhov ntev module | Qhov sib nrug yog qhov zoo tshaj plaws los ntawm qhov pib | Qhov sib txawv tsis sib haum pom tom qab kev teeb tsa - rov ua haujlwm dua |
| Ru tsev panels thiab module txhawb tsim los ua ib qho | Ib txheej txuas tsawg dua | Ib txheej txuas ntxiv txhais tau tias muaj kev pheej hmoo ntxiv |
| Loads, waterproofing, cabling thiab xob laim tiv thaiv ntawm ib daim duab | Ib lub koom haum site ib leeg | Ob tug neeg ua haujlwm nyob rau hauv ib ntus - ob npaug rau lub sijhawm |
Daim Duab Tus Nqi Tag Nrho
Raws li cov ntaub ntawv ntsuas: kev sib xyaw tsim txuag 8-12% nyob rau hauv tag nrho cov steel noj piv nrog ob-theem mus kom ze ntawm "tsim tus qauv ua ntej, ntxiv hnub ci tom qab".
Ntxiv nyob rau hauv tsis muaj zog, tsis muaj downtime, thiab overlapping lub sij hawm - rau ib tug tshiab cog project, tag nrho cov kev txuag los ntawm kev sib xyaw tsim mus deb tshaj tus naj npawb:
| Tus nqi | Integrated Design | Ua ntej, Retrofit Tom qab |
| Txhim kho tus nqi | 0 | 15% -25% ntawm pob nyiaj siv |
| Downtime poob | 0 | Nyob ntawm cov kab ntau lawm |
| Kev siv hlau | Lub hauv paus (txuag 8-12%) | Lub hauv paus + cov ntaub ntawv ntxiv dag zog |
| Lub koom haum site | Ib tug neeg coob, ib tug hla | Ob txoj kev tsim qauv, ob qho kev txhawb nqa |
Vim li cas Solar-Steel Integration Tsis tshua muaj
Steel fabricators tsis nkag siab txog kev xaiv hnub ci; Cov neeg muab khoom siv hnub ci tsis nkag siab txog cov khoom siv. Cov pab pawg uas nkag siab ob qho tib si tsis tshua muaj nyob hauv khw.
Dab tsi ua rau ZM-Besta lub peev xwm loj hauv kev lag luam: tsib lub hauv paus tsim khoom nrog 300,000 m² ntawm lub Hoobkas; Tshwj xeeb Qib A kev tsim nyog nyob rau hauv lub teeb steel qauv engineering tsim, Tuam Tshoj steel qauv fabrication tsim nyog (Special Grade), Qib I dav siv kev cog lus, thiab Qib I kev cog lus rau steel qauv ua haujlwm; ntxiv rau cov khoom siv hnub ci tsim nws tus kheej (cov chaw nres tsheb hnub ci hluav taws xob thiab BIPV cov kev daws teeb meem).
Cov ntawv pov thawj: EN 1090 (CE) thiab ISO 9001 / 14001 / 45001 kev tswj hwm qhov system trio.
Tsuas yog thaum cov qauv thiab hnub ci nyob hauv tib lub tuam txhab ua cov duab kos tau txais lub sijhawm ntsib.
FAQ
Q1: Dab tsi yog qhov txawv ntawm BIPV thiab PEB?
A: BAPV mounts modules mus rau lub tsev ua tiav, yog li cov qauv yuav tsum tau kuaj xyuas thiab ntxiv dag zog; BIPV kho lub hnub ci raws li ib feem ntawm lub tsev lub hnab ntawv, ua ke nrog lub ru tsev thiab thauj khoom los ntawm theem tsim. Qhov kev tsim qauv sib tham tau tham ntawm no yog txoj hauv kev BIPV.
Q2: Ib tsob nroj uas twb muaj lawm puas tuaj yeem tau txais lub hnub ci ru tsev?
A: Yog, tab sis pib nrog kev ntsuam xyuas cov qauv. Yog tias cov purlins muaj cov npoo txaus, nruab ncaj qha; yog tsis yog, ntxiv dag zog rau hauv zos. Xa peb daim ntawv ntsuam xyuas thiab peb yuav ua qhov kev ntsuam xyuas dawb.
A: Thaum lub load tau suav nrog hauv cov qauv ntawm cov qauv tsim, steel noj tsuas yog nce me ntsis - thiab tag nrho, kev tsim qauv tseem txuag tau 8-12% piv rau ob-theem mus kom ze.
Q4: Hnub ci tuaj yeem mus rau saum lub dome cia silo?
A: Yog. Lub dome yog qhov chaw-thav duab qauv; curved solar panels ua raws li lub plhaub, thiab cov loads hloov hauv lub plhaub mus rau lub nplhaib beam. Nws adapts zoo. Saib peb cov kev daws teeb meem hnub ci dome kom paub meej.
Q5: Leej twg ua lub luag haujlwm tag nrho rau qhov kev sib koom ua ke?
A: ZM-Besta ua ib lub luag haujlwm rau kev tsim, tsim thiab teeb tsa. Cov qauv thiab hnub ci yog kos los ntawm tib lub tuam txhab - qhov cuam tshuam tsawg tshaj plaws thiab qhov kev thov qis tshaj plaws.
