Scaffolding Pipes yog dab tsi?
Scaffolding yog ib qho qauv siv ib ntus siv hauv kev tsim kho kev tsim kho los txhawb cov neeg ua haujlwm thiab cov khoom siv. Nws yog ib qho tseem ceeb ntawm cov thav duab ua los ntawm ntau qhov chaw uas haum ua ke los tsim lub platform ruaj khov. Scaffolding kav yog ib qho tseem ceeb ntawm cov qauv no thiab ua lub luag haujlwm tseem ceeb hauv nws txoj kev ncaj ncees thiab kev ruaj ntseg. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog dab tsi scaffolding kav yog ua los ntawm thiab lawv cov khoom nyob rau hauv kom meej.
Dab tsi yog scaffolding kav?
Scaffolding kav yog hollow, cylindrical raj uas yog siv los ua lub hauv paus tsev blocks ntawm scaffolding lug. Cov kav dej no feem ntau yog ua los ntawm cov hlau, tab sis lawv tuaj yeem ua los ntawm txhuas lossis lwm yam ntaub ntawv. Txoj kab uas hla ntawm cov kav dej sib txawv nyob ntawm seb lawv xav siv, tab sis lawv feem ntau yog nyob nruab nrab ntawm 1.5 thiab 3.5 nti hauv txoj kab uas hla.
Cov kav dej feem ntau txuas nrog ua ke siv cov couplings lossis fittings uas tsim los kom haum cov kav dej snugly. Cov fittings no feem ntau yog ua los ntawm cov hlau thiab ua qhov sib txuas ntawm cov kav dej ntau yam. Thaum cov kav dej txuas nrog, lawv tuaj yeem npaj rau hauv ntau yam kev teeb tsa los tsim kom muaj cov qauv ruaj khov thiab ruaj khov.
Dab tsi yog cov kav dej scaffolding ua los ntawm?
Hlau yog cov khoom siv feem ntau siv los ua cov kav dej scaffolding. Qhov no yog vim cov hlau muaj zog, ruaj khov, thiab muaj peev xwm tiv taus qhov hnav thiab tsim kua muag ntawm kev ua haujlwm hnyav. Cov hlau siv rau cov kav dej Scaffolding feem ntau yog cov muaj zog ntau yam, uas txhais tau hais tias nws muaj lub zog ntau dua thiab tuaj yeem tiv taus ntau dua li cov qauv hlau.
Cov hlau siv rau cov kav dej Scaffolding feem ntau yog ua los ntawm cov hlau tsis muaj cov pa roj carbon tsawg, uas txhais tau hais tias nws muaj tsawg dua 0.3% carbon los ntawm qhov hnyav. Qhov no ua rau cov hlau yooj yim dua rau welding thiab tsis nkig dua li cov hlau uas muaj cov pa roj carbon ntau. Cov hlau kuj feem ntau yog kub-dipped galvanized, uas txhais tau hais tias nws tau coated nrog ib txheej ntawm zinc los tiv thaiv nws los ntawm xeb thiab corrosion.
Aluminium yog lwm cov khoom siv uas qee zaum siv rau cov kav dej. Aluminium yog sib dua thiab ntau dua corrosion-resistant dua hlau, ua rau nws yog ib qho kev xaiv zoo rau siv nyob rau hauv cov cheeb tsam uas muaj high humidity los yog dej ntsev raug. Txawm li cas los xij, txhuas feem ntau kim dua hlau thiab tej zaum yuav tsis muaj zog lossis ruaj khov.
Cov khoom ntawm scaffolding kav
Cov khoom ntawm scaffolding kav yog qhov tseem ceeb rau kev nyab xeeb thiab ruaj khov ntawm cov qauv scaffolding. Qee qhov tseem ceeb tshaj plaws ntawm cov kav dej scaffolding muaj xws li:
- Lub zog: Scaffolding kav yuav tsum muaj zog txaus los txhawb qhov hnyav ntawm cov neeg ua haujlwm thiab cov ntaub ntawv tsis muaj dabtsi yog khoov lossis tawg.
- Kev nruj: Scaffolding kav yuav tsum nruj txaus los tiv thaiv deflection thiab tswj lawv cov duab nyob rau hauv load.
- Durability: Scaffolding kav yuav tsum muaj peev xwm tiv taus qhov hnav thiab tsim kua muag ntawm kev tsim kho kev ua haujlwm yam tsis muaj kev tawg lossis lwm yam kev puas tsuaj.
- Corrosion tsis kam: Scaffolding kav yuav tsum tiv taus xeb thiab corrosion tiv thaiv kom tsis muaj zog thaum lub sij hawm.
- Weldability: Scaffolding kav yuav tsum yooj yim rau weld kom tso cai rau kev tsim cov kev sib txuas ruaj khov ntawm cov kav dej thiab fittings.

Scaffolding kav yog ib qho tseem ceeb ntawm cov qauv scaffolding, thiab lawv cov khoom yog qhov tseem ceeb rau kev nyab xeeb thiab ruaj khov ntawm scaffolding. Hlau yog cov khoom siv ntau tshaj plaws siv rau cov kav dej scaffolding vim nws lub zog, ruaj khov, thiab muaj peev xwm tiv taus corrosion. Aluminium yog lwm cov khoom siv uas tuaj yeem siv rau cov kav dej, tab sis nws feem ntau kim dua hlau. Los ntawm kev nkag siab txog cov khoom ntawm cov kav dej scaffolding, cov neeg tsim khoom tuaj yeem tsim cov qauv scaffolding muaj kev nyab xeeb thiab ruaj khov uas tuaj yeem txhawb cov neeg ua haujlwm thiab cov ntaub ntawv ntawm qhov siab zoo.
