Txij Nkawm Ntawm Scaffolding
Xyoo tsis ntev los no, tib neeg tau them ntau dua thiab ntau rau cov ncauj lus ntawm" txij nkawm" ;. Txhua yam uas xav ua kom ntev nws lub neej kev pabcuam yuav tsum muaj kev tiv thaiv thiab tsim kho kom nws nyob hauv lub xeev ib txwm muaj. Nyob rau lub sijhawm no, scaffold yuav ua li cas los ua nws txoj haujlwm txij nkawm yog qhov tsim nyog heev. Scaffolding yog lub chaw haujlwm tseem ceeb hauv kev tsim kho vaj tse, scaffold yog li ua nws txoj haujlwm tu tsev yog lub luag haujlwm tsim kev ruaj ntseg kev tsim kho. Yog li yuav ua li cas yuav tsum tau scaffold tswj?
Yog tias muaj dabtsi yog khoov lossis deformation ntawm tus pas nrig, scaffold nws yuav tsum tau ncaj ncaj ua ntej, thiab cov khoom siv tsis zoo yuav tsum tau kho kom zoo ua ntej kom ntseeg tau tias nws tuaj yeem siv ib txwm siv hauv kev tsim kho. Cov scaffolds hauv kev siv (suav nrog cov khoom siv sib txuam) yuav tsum xa rov qab mus rau lub chaw siv nyiaj thiab khaws cia ib qho sib cais. Thaum muab tso rau hauv qhov chaw qhib cua, scaffold xyuas kom meej tias qhov chaw ntim yog tiaj thiab zoo dej, muaj ntaub thaiv txhawb kom zoo hauv qab thiab npog nrog lub tarpaulin. Cov khoom siv kho thiab cov khoom siv yuav tsum muab tso rau sab hauv tsev.
Txog cov xeb tshem tawm thiab tiv thaiv xeb kho ntawm cov khoom siv, scaffold thov cov tshuaj tiv thaiv xeb tsawg kawg ib xyoos ib zaug hauv cov cheeb tsam uas muaj cov av noo (ntau dua 75%). Cov fasteners yuav tsum tau oiled, scaffold thiab bolts yuav tsum tau galvanized los tiv thaiv xeb. Yog tias tsis muaj qhov mob rau galvanizing, nws yuav tsum tau ntxuav nrog kerosene tom qab siv txhua zaus, scaffold thiab tom qab ntawd muab coated nrog cov roj cav los tiv thaiv xeb. Cov khoom siv me me xws li cov khawm ris, cov txiv ntoo, cov rov qab phaj, cov pob tw thiab cov ntsia hlau uas siv hauv cov ntawv scaffolding yog ib qho yooj yim ploj. Cov khoom seem yuav tsum tau ua dua tshiab thiab khaws cia rau hauv lub sijhawm thaum lawv tau txhim tsa, ua pob thiab kuaj thiab lees paub hauv lub sijhawm thaum lawv raug tshem tawm.
