Yog tias koj xa cov khoom scaffolding mus rau Tebchaws Europe lossis koom nrog cov haujlwm engineering hauv EU, EN 12810 thiab EN 12811 yog ob qho qauv qauv uas koj tsis tuaj yeem hla. Ob tus qauv no tsim cov txheej txheem ua tiav rau EU cov cai ntawm kev ua haujlwm scaffolding thiab cov qauv tsim, thiab ua haujlwm dhau los rau cov khoom kom tau txais ntawv pov thawj CE thiab nkag mus rau European lag luam.
Txawm li cas los xij, ntau lub tuam txhab lag luam hauv Suav teb thiab cov neeg xa tawm tau muaj kev nkag siab tsis zoo txog ob tus qauv no:
❌ Kev ntseeg yuam kev tias "tau txais daim ntawv pov thawj CE sib npaug nrog EN 12810/12811"
❌ Tsis meej pem qhov txawv ntawm "cov qauv kev ua tau zoo" thiab "tus qauv tsim"
❌ Tsis paub meej li cas cov qhab nia hauv chav kawm txuas nrog cov khoom tshwj xeeb
❌ Tsis paub txog cov ntsiab lus ntawm cov khoom xeem thiab cov cai coj mus kuaj
1. Kev sib raug zoo ntawm EN 12810 thiab EN 12811 yog dab tsi?
Nov yog thawj lo lus nug rau ntau tus nyeem. Nyob rau hauv qhov tseeb, ob qho tib si complementary thiab sib koom ua ib tug ua tiav kev specification system rau scaffolding:
EN 12810 tsom rau"txawm tias cov khoom nws tus kheej tsim nyog"(qib khoom)
EN 12811 tsom rau"yuav ua li cas xam qhov kev nyab xeeb ntawm tag nrho cov qauv"(Engineering Level)
Ua ke, lawv npog tag nrho cov kev tswj xyuas zoo los ntawm cov khoom siv raw → Cheebtsam → systems → tag nrho cov qauv.
2. Kev txhais cov ntsiab lus ntawm EN 12810-1: Kev Ua Haujlwm Yuav Tsum Tau Ua Dab Tsi?
EN 12810-1 yog cov khoom lag luam qib tus qauv tshwj xeeb ntawm European scaffolding qauv. Nws lub ntsiab lus nug tseem ceeb yog:"Qhov ntsuas kev ua tau zoo dab tsi yuav tsum muaj peev xwm ua tau raws li qhov tsim nyog facade facade scaffolding system kom ua tau raws li qhov yuav tsum tau ua?"
TS EN 12810-1 AKev ua tau zoo-Txoj Kev Ua Raws Cai: nws tsis tso cai rau cov ntaub ntawv tshwj xeeb lossis cov qauv, tsuas yog qhov kev ua tau zoo kawg nkaus uas cov khoom yuav tsum ua tiav, thiab kev ua raws cai tau tso cai ntev npaum li qhov ua tau raws li qhov yuav tsum tau ua. Lub tswv yim no hloov tau yooj yim dua, tab sis kuj tso siab rau cov kev xav tau siab dua rau cov tuam txhab kev nkag siab txog kev muaj peev xwm.
Scope ntawm daim ntawv thov
EN 12810-1 feem ntau yog lub hom phiaj prefabricated facade scaffolding, piv txwv li scaffolding systems nrog lub Hoobkas- qauv tsim thiab ntawm- qhov chaw sib dhos. Nws suav nrog cov khoom xa tawm feem ntau suav nrog ringlock, cuplock, thav duab, thiab cov tshuab modular, tab sis tsis siv rau cov tsoos fastener - hom steel yeeb nkab scaffolding thiab tshwj xeeb-zoo li tus scaffolding. Qhov kev txhais no ua rau daim ntawv thov ntawm tus qauv meej meej, thiab zam kev tsis meej pem ntawm cov tshuab sib txawv.
6 Core Performance Dimensions
TS EN 12810-1 - Ntu 1: Cov ntsiab lus tseem ceeb:
Geometry thiab cov qauv tsim: Nws tau teev tseg tias cov kev txwv tsis pub muaj xws li qhov sib nrug ncaj, cov kauj ruam ntawm cov kauj ruam deb, thiab kev ua haujlwm platform dav yuav tsum nyob rau hauv qhov tsim nyog los xyuas kom meej qhov kev siv tau yooj yim.
Cov kev xav tau ntawm lub zog (core ntawm tus qauv): Nws xav kom cov pas nrig thiab cov kab sib txuas (xws li rosettes, cuplocks, thiab clamps) yuav tsum muaj tensile txaus, compressive, dabtsi yog khoov, thiab torsional tsis kam, thiab qhov kev ua tau zoo no yuav tsum tau txheeb xyuas los ntawm cov qauv ntsuas.
Cov kev cai ruaj ntseg: Nws hais tias tag nrho cov ncej yuav tsum tsis txhob raug kev txom nyem los ntawm tag nrho cov instability los yog overturning nyob rau hauv lub ua ke ntawm nws tus kheej - nyhav, nyob load, cua load, thiab lwm yam.
Load-cov kev cai muaj peev xwm (feem ntau tshwj xeeb): Nws faib cov chaw ua haujlwm rau hauv 6 Chav Kawm Kev Ntsuas (Class 1 txog Chav Kawm 6) raws li kev thauj khoom- cov kabmob muaj peev xwm, nrog rau cov khoom sib xws uas nce qib los ntawm 0.75 kN / m² mus rau 6.0 kN / m², thiab ib qho hnyav hnyav ntawm 1.5 kN. Cov tuam txhab lag luam tuaj yeem xaiv cov qib sib txuam raws li cov ntawv thov sib txawv.
Durability yuav tsum: Tus qauv muaj cov kev cai meej ntawm kev tiv thaiv kev tiv thaiv corrosion: qhov nruab nrab thickness ntawm kub -dip galvanized txheej yuav tsum tsis pub tsawg tshaj 55 microns, thiab lub zos thickness yuav tsum tsis txhob tsawg tshaj li 45 microns, thiab corrosion kuj yuav tsum tau xyuas los ntawm ib tug tshuaj tsuag ntsev.
Cov kev cai ua haujlwm kev nyab xeeb: Cov txheej txheem muaj cov ncauj lus kom ntxaws txog cov guardrails, ntiv taw boards, platform planks, kev tiv thaiv lub caij nplooj zeeg, thiab lwm yam, kom ntseeg tau tias tus kheej kev nyab xeeb ntawm cov neeg ua haujlwm thaum ua haujlwm.
Lub ntsiab tseem ceeb: Chav Kawm Qib Siab System
Ntawm txhua qhov yuav tsum tau ua, Chav Kawm Qib Siab ntawm EN 12810-1 yog qhov tsim nyog tshaj plaws ntawm kev nkag siab tob los ntawm Suav cov lag luam xa tawm. Tus qauv tsim cov txheej txheem qhia tus kheej zoo ib yam li "cov khoom ID card" los ntawm kev sib xyaw ntawm peb qhov loj:
Upright spacing (SW rau qhov me me lossis LW rau qhov sib txawv loj)
Load class (Class 1-6)
Platform tiv thaiv configuration (4 qib ntawm H0 txog H3)
Txhua yam khoom ua raws cai yuav tsum muaj cov lej ua tiav hauv chav kawm, uas yuav tsum tau muab cim tas mus li thiab meej meej rau ntawm daim ntawv teev npe. Piv txwv li, ib qho kev sib koom siab -kawg configuration"3D - SW06/250 - H2 - B"txhais tau hais tias: thauj khoom Class 3 (suav nrog 2.0 kN / m²), upright spacing ntawm 2.5m, ua hauj lwm platform dav ntawm 0.6m, platform tiv thaiv configuration H2 (ob chav ledgers ntxiv rau ntiv taw), thiab tshwj xeeb muaj nuj nqi B.
Qhov no "code sib npaug kev ntsuas" lub tswv yim tseem ceeb txhawb nqa scaffolding, ib txwm suav tias yog "cov cuab yeej siv dav dav", mus rau qib ntawm cov khoom siv traceable, sib piv, thiab cov khoom pov thawj engineering.
Tus nqi tiag tiag ntawm EN 12810-1 tus qauv kev ua tau zoo yog txhawm rau cuam tshuam kev cuam tshuam ntawm cov teb chaws Europe, tso cai rau kev sib piv cov khoom los ntawm cov tuam txhab sib txawv raws li kev cai sib koom ua ke, thiab txhawb kev tsim kho tshiab: tsuav koj tuaj yeem ua pov thawj cov khoom ua tau raws li qhov yuav tsum tau ua, koj tuaj yeem muag hauv European lag luam txawm tias koj siv cov khoom thiab cov qauv.
3. Kev txhais cov ntsiab lus ntawm EN 12811-1: Yuav ua li cas coj tus qauv tsim kev suav lej?
Yog tias EN 12810 tsom rau "txawm tias cov khoom siv scaffolding tsim nyog", EN 12811-1 tsom rau "yuav ua li cas xam cov qauv scaffolding kom muaj kev nyab xeeb". Nws yog lub hauv paus txheej txheem rau European scaffolding tsim, thiab yog qhov tseem ceeb ntawm cov lus qhia rauLimit State Design, uas muaj qhov sib txawv ntawm lub tswv yim los ntawm cov txheej txheem kev ntxhov siab uas tau teev tseg hauv Tuam Tshoj tus qauv JGJ 202 tam sim no.
Core Logic: 3 Load Types + 5 Limit States + 1 Teem pov thawj
3 Load Hom: Cov neeg tsim qauv yuav tsum tau ua tib zoo xav txog peb hom kev ua thiab ua kev suav superposition raws li lub hauv paus ntsiab lus ntawm kev sib xyaw ua ke tsis zoo:
Kev thauj mus tas li: Lub Sijhawm- qhov tsis sib xws xws li scaffolding tus kheej- hnyav, platform plank hnyav, guardrail hnyav
Cov khoom sib txawv: Cov khoom hnyav xws li cov neeg ua haujlwm, cov khoom sib dhos, cov khoom siv tsim kho (sib faib ua 6 qib ntawm 0.75 txog 6.0 kN / m² raws li Chav Kawm 1 txog Chav Kawm 6)
Environmental loads: Cua load, daus load, kub nyhuv
5 txwv lub xeev kom paub tseeb:
Qhov kawg txwv lub xeev ntawm cov kabmob muaj peev xwm: Cov qauv yuav tsum tsis txhob puas lossis tsis ruaj khov
Serviceability txwv lub xeev: Deformation thiab deflection yuav tsum nyob rau hauv ntau npaum li cas (platform deflection yuav tsum tsis txhob ntau tshaj 1/100 ntawm lub ncua)
Overturning limit state: Zuag qhia tag nrho los tiv thaiv -overturning stability coefficient yuav tsum tsis pub tsawg tshaj 1.5
Sliding limit state: Tsis muaj slippage ntawm lub hauv paus hauv qab thiab hauv av
Fatigue limit state: Fatigue checking laij lej rau kev sib txuas ntawm cov pob txha rov ua dua
Qhov ntau- lub tswv yim pov thawj hauv xeev no tuaj yeem cuam tshuam qhov tseeb ntawm qhov kev nyab xeeb ntawm cov qauv piv nrog cov qauv kev ntxhov siab ib txwm muaj.
Cov Ntsiab Cai Tsim
TS EN 12811-1 Cov lus qhia meej meej: qhov sib nrug ncaj yog feem ntau ntawm 1.0m thiab 3.0m, ledger kauj ruam nrug feem ntau yog 1.5 txog 2.0m, eccentricity ntawm lub platform ua haujlwm thiab phab ntsa yuav tsum tsis pub tshaj 100mm, qhov sib nrug ntawm khi cov tswv cuab raws txoj kab ntsug yuav tsum tsis pub tshaj 4m ntawm kev taw qhia thiab raws tus lej tib lub sijhawm ua haujlwm hauv pem teb yog suav tias tsis muaj ntau tshaj ob.
Cov tsis sib koom ua ke txiav txim siab tus qauv ntawm tag nrho cov thav duab: uprights yog yooj yim raws li nruam compression tuav nrog elastic kev txhawb nqa, khi cov tswv cuab yog suav tias yog kab rov tav caij nplooj ntoos hlav, cua loads hloov mus rau lateral rog faib raws lub façade, thiab tag nrho kev ruaj ntseg yog thaum kawg daws los ntawm ob -kev txiav txim elastic tsom xam los yog P- Δ txoj kev.
Cov ntsiab lus tseem ceeb rau kev xyaum
Qhov yooj yim tshaj plaws tau saib tsis tau tseem ceeb tshaj plaws ntawm EN 12811-1 yog kev tiv thaiv- rov qab xyuas kev suav thiab kev txheeb xyuas kev ruaj ntseg tag nrho. Ntau lub tuam txhab Suav cov khoom lag luam ua tau zoo heev hauv ib qho - cov khoom ntsuas raws li EN 12810-2, tab sis nthuav tawm cov teeb meem hauv cov ntawv thov siab siab tshaj 50m thaum kuaj xyuas EN 12811-1: qhov siab dua, qhov tseem ceeb ntawm cov cua load amplification nyhuv, thiab qhov zoo ntawm qhov ntev ntawm uprights hloov raws li. Hom kev tsis ruaj khov tag nrho tuaj yeem hloov ntawm "tus tswvcuab tsis ruaj khov" mus rau "txheej txheem lateral hloov chaw tsis ruaj khov", uas tsis tuaj yeem raug ntes los ntawm ib qho kev sim ntsuas.
Qhov no kuj yog vim li cas European Cov Lus Qhia Txog Lub Cev (xws li TÜV, DIBt) tsis tsuas yog tshuaj xyuas cov khoom lag luam cov ntaub ntawv thaum tshawb xyuas, tab sis kuj yuav tsum tau tsim cov ntaub ntawv suav thiab tag nrho cov ntaub ntawv pov thawj hauv qab kev ua haujlwm. Tus nqi tiag tiag ntawm EN 12811-1 yog tias nws yuam cov neeg tsim qauv txav los ntawm "ib zaug-cov ntsiab lus tsim nyog" mus rau "kev nyab xeeb ntawm lub cev" - qhov no tsis yog tsuas yog kev sim ntawm cov khoom, tab sis kuj yog ib qho kev sim ntawm kev tsim muaj peev xwm.
