Fastener-hom steel raj scaffolding yog dav siv nyob rau hauv peb lub teb chaws, thiab nws cov nyiaj pab tau ntau tshaj 60%. Tam sim no nws yog cov scaffold ntau tshaj plaws. Txawm li cas los xij, qhov tsis muaj zog loj tshaj plaws ntawm hom scaffolding no yog nws kev nyab xeeb tsis zoo, tsis siv kev ua haujlwm, thiab kev siv khoom siab. Tam sim no, muaj kwv yees li 10 lab tons ntawm scaffold hlau kav hauv lub teb chaws, ntawm uas tsis muaj txiaj ntsig yog li 80 txog 1% yog li 90% yog cov khoom lag luam. Xws li ntau ntawm cov kav hlau tsis tsim nyog hlau thiab cov fasteners tau dhau los ua kev phom sij nyab xeeb hauv kev tsim kho.
Raws li cov txheeb cais tsis tiav, txij li xyoo 2001 txog 2007, muaj ntau dua 70 tus kab yeeb uas muaj kev sib tsoo, nrog ntau tshaj 200 tus neeg raug mob. Nyob rau hauv xyoo tsis ntev los no, scaffold poob cov xwm txheej tau tshwm sim txhua xyoo, ua rau cov khoom lag luam hnyav thiab kev raug mob. Yog li ntawd, qee cov kws tshaj lij thiab cov neeg hauv tebchaws kev lag luam qhia tau hais tias cov cai hauv tebchaws qhia kom tshem tawm cov kev cai ceev-hom steel yeeb nkab Scaffolding.
Cov laj thawj yog li nram qab no:
01. Qhov zoo ntawm kuv lub teb chaws lub fastener steel scaffolding yog tiag tiag ntawm kev tswj hwm
Txheem JGJ1302002001 hauv cov lus 5.1.7 ceg ntseeg tias cov kabmob tawm tsam muaj peev xwm tiv thaiv cov kabmob muaj peev xwm ntawm txoj cai thiab lub ntsej muag rotating yog 8kn. Qee cov kws tshaj lij pom pom ntawm qhov kev kuaj xyuas ntawm cov khoom uas nws nyuaj rau cov khoom lag luam hauv kev thov kom tau raws li qhov yuav tsum tau ua. Tom qab ib qho kev sib tsoo loj tau tshwm sim ntawm qee qhov chaw tsim kho, cov fasteners tau kuaj xyuas thiab tus nqi dhau los 0%.
02. Qhov zoo ntawm cov yeeb nkab steel yog tiag tiag ntawm kev tswj hwm
Coob tus ntawm cov kav hlau tsis muaj kev tiv thaiv xeb tau zoo tau ntws mus rau hauv kev ua lag luam. Vim tias lawv tsis tau lees paub los ntawm kev tshuaj xyuas kom zoo, cov khoom tsis tuaj yeem muab cov qauv kev nyab xeeb zoo, uas tau ua txhaum txoj cai ntawm cov khoom tsis xws luag. Tsis tas li, qhov tseeb, kev tsim cov chav kawm thiab cov tuam txhab qiv khoom los ntawm kev sib tw styddy siv, thiab qee cov dej num siv cov khib nyiab hlau rau Scaffolding. Objectively, kev nyab xeeb ntawm lub tshuab luam-hom steel yeeb nkab scaffolding yog kiag li ntawm kev tswj lub xeev. Qee tus kws tshaj lij cov kws tshawb fawb cov kav hlau steel tom qab qhov kev sib tsoo loj hauv ib qho phiaj xwm, thiab tus nqi dhau tau tsuas yog 50%.
03. Nyob rau ntawm thaj chaw erection thiab kev tswj hwm kev nyab xeeb kev nyab xeeb
Qhov hloov pauv hloov tau thiab muaj ntau yam zoo tshaj plaws ntawm cov kab hlau nrawm nraus kuj nqa cov kev paub tseeb hauv lub xaib erection thiab kev tsim kho. Nws yog ib qho nyuaj rau cov kev pheej hmoo ruaj ntseg tshwm sim los ntawm qhov tsis muaj kev tswj hwm, tsis muaj kev sib koom ua ke thiab tsis muaj lub luag haujlwm vim kev sib sau ua ke.
04, daim ntawv thov tsis raug
Raws li cov kev paub ntawm cov teb chaws tsim, ceev-hom steel raj scaffolding thiab cov pob nyem uas yog pob zeb, thiab disc-khawm scaffolding, thiab disc-khawm scaffolding. Nws yuav tsum tsis txhob siv los txhim kho ib qho loj ntawm scaffolding system tsis tuaj yeem siv rau kev txhawb nqa cov tshuab uas xav tau cov ris nra hnyav. Hauv Tebchaws Asmeskas, txawm tias kev tsim kho thiab txij nkawm villas uas muaj ntau hom yeeb nkab cov nplaim hluav taws xob tsis tau siv los tsim cov platform. Qhov laj thawj yog qhov yooj yim. Yog tias siv nyob rau hauv txoj kev no, txawm tias qhov zoo ntawm American tus qauv fasteners thiab steel raj scaffolding yog tag nrho cov cai kev nyab xeeb. Txawm li cas los xij, vim tias txoj kev npaj ua erection yog qhov nyuaj rau kev ua kom zoo, thiab cov txheej txheem erection yog tsis tuaj yeem tswj tau ntau yam lus ntawm kev ua haujlwm ntawm phau ntawv kev nyab xeeb, thiab kev nyab xeeb tsis tuaj yeem lav. Nyob rau tib lub sijhawm, piv nrog portal lossis lub tais-hle scaffolding, daim ntawv thov tau ua ob npaug ntawm tag nrho cov phiaj xwm thiab poob nyiaj kev lag luam.
05. Tsis ncaj ncees
Ministry ntawm kev tsim kho cov neegsCov koom pheej ntawm Tuam Tshoj tau pom zoo "JGJ130-2001 kev nyab xeeb kev ua haujlwm rau lub Rau Hli 1, 2001. Nws yog ib qho kev lag luam ua haujlwm ua ntej lawm hauv kuv lub tebchaws. Nws yog ib qho tsim nyog rau erection thiab tshem tawm ntawm scaffolding hauv kuv lub teb chaws. Tus qauv tsim thiab kev tsim kho cov tuam txhab muaj kev cuam tshuam tob.
