Vim li cas cov blocks spacer ntsia nruab nrab ntawm guardrail panels thiab posts? Lawv muab cov txiaj ntsig dab tsi?
- Zog Absorption: Spacer blocks lawv tus kheej ua lub zog-absorbing mechanisms. Thaum muaj kev cuam tshuam, lawv tso cai rau lub guardrail deform maj mam, txhawb lub zog dissipation thiab txo qhov kev pheej hmoo ntawm kev raug mob hnyav rau cov neeg nyob hauv tsheb.
- Tiv thaiv Wheel Snagging: Los ntawm kev ruaj ntseg qhov thaiv qhov thaiv ntawm tus ncej thiab lub qhov rooj thaiv vaj huam sib luag, qhov sib txawv yog tsim. Qhov no tiv thaiv lub tsheb lub log pem hauv ntej los ntawm snagging ntawm tus ncej thaum muaj kev sib tsoo, uas tuaj yeem ua rau muaj kev cuam tshuam sai thiab txaus ntshai.
- Enhanced Force Distribution: Kev koom ua ke spacer blocks rau hauv lub guardrail system faib cov kev cuam tshuam quab yuam nyob rau hauv ib qho chaw dav dav. Qhov no ua rau muaj kev sib faib ntau dua ntawm kev ntxhov siab, ua rau muaj kev sib tsoo zoo dua rau lub tsheb, txhim kho nws txoj kev rov qab, thiab txhim kho tag nrho lub zog ntawm lub guardrail system.
- Mitigating Curb Impacts: Thaum txhim kho guardrails nrog spacer blocks nyob rau hauv seem nrog curbs, qhov kev ncua deb ntawm lub guardrail vaj huam sib luag thiab curb lub ntsej muag yog txo. Qhov no txo qis lossis txawm tias tshem tawm cov teebmeem tsis zoo ntawm lub tsheb tsoo qhov thaiv thiab tom qab ntawd vaulting rau hauv qhov chaw tiv thaiv.
Spacer blocks tuaj yeem tsim los ntawm ntau yam zoo li steel seem. Ob hom kev pom zoo feem ntau yog A thiab B. Hom A, nrog nws cov qauv hexagonal, yog tsim rau cov ncej puag ncig, thaum Hom B, raws li Fabkis cov qauv, yog tsim los rau C-shaped lossis lwm yam qauv steel ncej.
Hauv kev xaus, lub luag hauj lwm ntawm spacer blocks nyob rau hauv guardrail systems yog ib qho tseem ceeb thiab yuav tsum tsis txhob overlooked. Lawv ua rau lub cev muaj txiaj ntsig zoo hauv kev nqus lub zog, tiv thaiv tus cwj pwm ntawm lub tsheb txaus ntshai thaum sib tsoo, thiab txhim kho txoj kev nyab xeeb tag nrho.
