Siab -Kev Ua Haujlwm Rebar Spacers & Pob Tawb Txhawb Kev Txhawb Nqa
Rebar spacers thiab kev txhawb nqa tuav cov kev cai tshwj xeeb npog cov kev cai hla kab rov tav slab reinforcement, ntsug phab ntsa panels, kem tawb, thiab cov hauv paus hnyav. Qhov chaw npog meej tiv thaiv cov hlau oxidation, ua kom cov qauv thauj khoom hloov pauv, thiab ua kom muaj hluav taws kub - cov txheej txheem ntsuas kev tswj hwm los ntawm cov cai hauv tsev thoob ntiaj teb (xws li EN 1992-1-1 thiab ACI 318).
Kev ua vaj tse tsis raug ncaj qha ua rau muaj kev puas tsuaj thaum ntxov:
Lub hau npog tsis txaus nthuav tawm cov hlau txuas ntxiv rau cov dej noo, carbonation, thiab chloride ingress, ua rau spalling, ntxov ntxov corrosion, thiab seem poob.
Cov npog ntau dhau yuav txo cov txheej txheem qhov tob (d), ua kom tsis txhob muaj kev sib tsoo ntawm lub ntsej muag nro thiab txo cov txheej txheem shear thiab flexural muaj peev xwm.
Xaiv qhov tseeb spacer variant nyob ntawm formwork hom, rebar ceev, mechanical load thaum lub sij hawm ua vaj tse, thiab ib puag ncig raug cov chav kawm (xws li, XC, XS, XD).
