Dab tsi yog galvanized steel plank?
Galvanized Steel Plank kuj yog hu ua Hlau Platforms, Catwalk Scaffolding ET lwm yam Nws yog cov tshuaj Scaffolding, thiab lwm cov kev tsim khoom loj tsim khoom. Nws muaj hluav taws kub tiv thaiv, cov xuab zeb nce ntxiv, lub teeb yuag, muaj zog compressive ntawm ob sab, thiab lwm yam.
Cov txheej txheem ntau lawm ntawm galvanized steel yeeb nkab
Scaffolding Hlau Planksyog nquag siv nyob rau hauv lub scaffolding system, yog li qhov zoo ntawm scaffolding plank yuav tsum raug tswj hwm tswj tau thaum lub sijhawm tsim khoom.
Lub sab nraud sab nraud thiab ntev ntawm lub galvanized steel planks tsis txwv. Qhov dav dav yog 240mm, 250mm, thiab qhov siab yog 65 hli, 50mm, 45 hli, feem. Qhov ntev ntawm cov steel platform tso cai rau qhov yuam kev: qhov ntev yuav tsum tsis pub tshaj 3mm, qhov dav yuav tsum tsis pub tshaj 2.0 hli, thiab qhov siab yuav tsum tsis pub tshaj li 1.0mm.
Lub qhov taub uas hla (12mmx18mm), lub qhov deb (30.5mmx40mm), cov flanging yog punched, lub ntsej muag yog 2 hli, thiab qhov siab flanging yog 1.5mm. Qhov tsis-qab txoj kev uas hla ntawm lub rooj tsavxwm yuav tsum tsis pub tshaj 2.0 hli, thiab lub qhov ua tsis tau zoo tshaj 0.5mm.
Cov kab khoov tam li ntawm cov hlau planks yuav tsum yog 90 °, thiab qhov yuam kev yuav tsum tsis pub tshaj 2 °.
Qhov saum npoo ntawm cov steel spewboard yuav tsum tiaj, thiab deflection ntawm lub cim yuav tsum tsis pub tshaj 5.0 hli. Daim duab peb sab-puab zawj nrog cov ruaj khov zoo dua yog xaiv rau ntawm lub rooj tsavxwm, uas yog kev npaj ntau dua li cov neeg thib peb kub-dip Galvanoidal Gracezoidal. Rau kev tshawb fawb, nws yog tiv taus ntau ntxiv rau compression thiab ruaj khov.
Plaub lub kaum ntawm cov steel platform yog qaij cov hlau planks, cov neeg dig muag ntawm plaub fab yog stagoned, thiab nws yuav tsum tsis pub tshaj 5.0mm.
Burrs xws li ntug ntawm cov txheej txheem steel yuav tsum tau ua ntawv thov.
Sab nraub qaum ntawm cov pob zeb hlau yog embedded nrog slotted stiffening tav txhua 500 ~ 700mm. Lub stiffener deb yuam kev ntawm cov pob zeb hlau yuav tsum tsis pub tshaj 0.5 hli, thiab cov lus xaus yuam kev yuav tsum tsis pub tshaj 2.0mm.
Cov vuam vuam: Cov ntawv Welds) yog siv rau cov todplates thiab tawg welds rau cov stiffeners. Cov welds yuav tsum tsis pub tsawg tshaj 2.0mm, thiab qhov dav ntawm cov welds yuav tsum tsis pub tsawg tshaj 2.0mm. Qhov ntev ntawm txhua txuas ntxiv vuam sib khi ntawm lub stiffener yuav tsum tsis pub tsawg tshaj 10mm, thiab cov hlua khi yuav tsum tsis pub tsawg tshaj 10. Qhov ntev ntawm lub vuam sib koom ua ke yog ≥15mm, lub vuam sib koom tes yog ≥6, thiab cov ntaub ntawv sib dhos ntawm txoj hlua khi siab yog ≥2mm. Lub taub hau vuam ntawm cov lus endplate yuav tsum ntau tshaj 7 cov ntsiab lus vuam, thiab vuam sib dhos ntawm ob tog, thiab cov vuam sib dhos ntawm ob tog, thiab cov vuam sib dhos ntawm ob sab.
Qhov saum npoo ntawm cov steel spreidoard yuav tsum yog degreing thiab txiav tawm, thiab tom qab ntawd txiav tawm. Nws yog qhov yuav tsum tau thov primer ib zaug thiab topcoat ib zaug, thiab cov tuab ntawm txhua zaj yeeb yaj kiab xim yuav tsum tsis pub tsawg tshaj li 25μm.
Txhua pob ntawm kub-dip galvanized steel ntawv sau lub Hoobkas yuav tsum tau muab cov ntaub ntawv pov tseg lossis cov ntawv xeem tawm los ntawm kev sim cov koom tes.
