Thaum cov degree ntawm xeb yog ntau dua 0.5 hli, cov yeeb nkab steel mus txog ntawm cov qauv ntawm cov qauv ntawm cov qauv thiab yuav tsum tsis siv.
(2) Fasteners:
1) pov cov hlau sib txuas yuav tsum siv, thiab cov khoom siv yuav tsum ua raws qib KH330-80-80
2) Lub chaw tsim khoom lag luam cov ntawv tso cai tsim cov ntawv tso cai, khoom pov thawj khoom lag luam, thiab daim ntawv pov thawj khoom tsim nyog yuav tsum muaj.
3) Fasteners yuav tsum tsis muaj cov tawg, npuas, deforming, xov daig, lossis lwm yam xo hau, lossis lwm yam cam khwb cia hlau tsis xws luag uas cuam tshuam rau kev siv ua haujlwm. Cov xuab zeb ci, nchuav cov ris tsho, seem tawg, cov nplai oxide, thiab lwm yam uas cuam tshuam rau cov tsos zoo yuav tsum ntxuav kom huv.
4) Lub khawm khawm khawm thiab cov yeeb nkab steel yuav tsum haum kom nruj ua ke thiab muaj kev sib khi zoo thaum muab cov yeeb nkab ceev. Thaum cov ntsia hlau zawm lub zog txog li 65nk, tus neeg ua haujlwm nrawm yuav tsis tawg.
5) Cov npoo ntawm lub fastener yuav raug kho nrog xeb kev tiv thaiv.
(3) scaffolding

Plaub, yuav tsum tau rau kev ua kom erection ntawm Scaffolding ncej
(1) Lub hauv paus yuav tsum ua kom tau raws li cov kev thauj khoom ntawm tag nrho cov duab scaffolding tag nrho thiab yog 50 hli ~ 100m saum toj no hauv av. Kev ntsuas cov roj yuav tsum tau ua ib ncig nws.
(2) Tus ncej ncej yuav tsum muab tso rau ntawm sab qaum ntawm lub hauv paus, uas yuav tsum ntau tshaj 50 hli saum lub hauv paus; Thaum siv ntaub qhwv ntoo ntoo, lub hauv paus yuav tsum tau ntxiv.
(3) Cov kauj ruam nyob deb ntawm cov scaffolding hauv qab txheej yuav tsis pub tshaj 2 meters, thiab cov ncej yuav tsum tau ntseeg nrog lub tsev qauv nrog phab ntsa sib txuas cov pas nrig.
(4) Rau qhov ncua ntawm cov ncej ntsug, tshwj tsis yog rau kauj ruam saum toj kawg nkaus ntawm cov theem saum toj, uas tuaj yeem sib txuas, cov pob qij txha sib txuas ntawm lwm qhov chaw yuav tsum sib txuas los ntawm lub pob tw fasteners. Cov kev cai tshwj xeeb muaj raws li hauv qab no: lub taub qab rollowers ntawm tus ncej ntsug yuav tsum yog staggered, thiab cov pob qij tes yuav tsum tsis txhob teeb tsa hauv tib qho kev coj. Qhov ob leeg sib cais sib cais los ntawm ib ntsug ntsug yuav tsum yog qhov tsis muaj tsawg dua 500m, thiab qhov kev ncua deb ntawm nruab nrab ntawm txhua qhov sib koom tes yuav tsis muaj ntau dua 1/3 ntawm cov kauj ruam.
(5) Sab saum toj ntawm txoj kab ntsug yuav tsum tsis pub tsawg tshaj 1m saum toj no cov tawv nqaij parapet thiab 1.5m saum toj no eaves.
