Cov neeg feem coob xav tias cov ntsia hlau shear yog cov ntsia hlau welded, tab sis qhov tseeb lawv yog ob yam sib txawv ntawm cov ntsia hlau txuas.
1. Shear ntsia thawv yog ib hom kev sib txuas siv hauv cov qauv steel-pob zeb sib xyaw. Lawv feem ntau yog ua los ntawm cov hlau muaj zog thiab muaj cov duab tshwj xeeb thiab cov yam ntxwv geometric. Lub luag haujlwm tseem ceeb yog hloov lub zog transverse thiab dabtsi yog khoov lub sijhawm los ntawm kev tiv thaiv shear quab yuam, thiaj li paub txog kev sib txuas muaj zog ntawm cov qauv steel thiab pob zeb. Shear ntsia hlau feem ntau yog siv rau hauv cov choj, hauv pem teb, kev txhawb nqa thiab lwm yam qauv.
ob.. Lub vuam ntsia hlau yog ib hom kev sib txuas kho los ntawm vuam. Lawv feem ntau yog ua los ntawm cov khoom siv hlau thiab muaj cov ntsia hlau zoo li tus ntsia thawv. Lub vuam tus pin txuas nws ruaj khov rau lwm qhov chaw ua haujlwm los ntawm vuam ib kawg mus rau lwm qhov chaw ua haujlwm. Vuam cov ntsia hlau tuaj yeem pom tau los ntawm kev sib txawv vuam xws li qhov chaw vuam, sib txhuam vuam thiab lwm yam. Vuam cov ntsia hlau feem ntau siv hauv cov qauv hlau, kev tsim tsheb, kev tsim khoom siv tshuab thiab lwm yam.
Nws yuav tsum tau muab sau tseg tias muaj kev sib txawv ntawm cov ntsia hlau shear thiab welded rau tes nyob rau hauv cov nqe lus ntawm kev siv, cov ntaub ntawv thiab kho txoj kev. Shear rau tes yog tsuas yog siv nyob rau hauv steel-concrete lug hloov transverse quab yuam thiab dabtsi yog khoov lub sij hawm los ntawm resisting shear quab yuam, thaum vuam rau tes yog tsuas yog siv nyob rau hauv cov hlau lug txhim kho workpieces los ntawm vuam. Kev xaiv cov khoom sib txuas tsim nyog yuav tsum tau txiav txim siab raws li kev thov tshwj xeeb thiab cov qauv tsim.
Thaum nws los txog rau shear rau tes thiab welded rau tes, lawv cov yam ntxwv thiab kev siv tau tuaj yeem tham ntxiv:
Cov yam ntxwv ntawm cov ntsia hlau shear:
1. Lub zog siab: cov ntsia hlau shear feem ntau yog ua los ntawm cov hlau muaj zog thiab tuaj yeem tiv taus cov shear loj thiab kev sib hloov.
ob.. Cov duab tshwj xeeb: cov ntsia hlau shear muaj cov duab tshwj xeeb thiab cov duab geometric los txhim kho lawv cov shear tsis kam thiab kev sib txuas ruaj khov.
3. Tsim nyog rau cov pob zeb ua vaj tse: cov ntsia hlau shear feem ntau yog siv hauv cov khoom siv steel-pob zeb sib xyaw, xws li txuas hniav, pem teb, thiab lwm yam, kom paub txog kev sib txuas ntawm cov hlau thiab pob zeb.
Cov yam ntxwv ntawm cov ntsia hlau welding:
1. Zoo nruj: cov ntsia hlau vuam yog kho los ntawm vuam, uas tuaj yeem muab kev sib txuas ruaj khov thiab muaj kev nruj nruj.
ob.. Ntau yam kev siv vuam: vuam cov ntsia hlau tuaj yeem siv txoj kev vuam sib txawv, xws li qhov chaw vuam, sib txhuam vuam, thiab lwm yam, kom ua tau raws li cov kev xav tau sib txawv.
3. Haum rau cov qauv hlau: vuam cov ntsia hlau yog siv rau hauv cov qauv hlau, xws li hlau ncej, tsheb tsim, tshuab tsim thiab lwm yam, kom paub txog kev sib txuas ntawm cov hlau.
Nws yuav tsum raug sau tseg tias thaum siv cov ntsia hlau shear lossis cov ntsia hlau welded, cov kev sib txuas tsim nyog yuav tsum raug xaiv raws li cov qauv tsim tshwj xeeb thiab cov ntawv thov. Thaum xaiv cov ntsia hlau los yog cov ntsia hlau welded, nws yog ib qho tsim nyog yuav tsum xav txog qhov yuav tsum tau ua ntawm cov qauv, cov yam ntxwv ntawm cov khoom siv, kev tsim kho tshuab thiab lwm yam los xyuas kom meej qhov ruaj khov thiab kev ntseeg siab ntawm kev sib txuas.
