Khoom Description
S235 yog dab tsi?
S235 yog cov ntsiab lus ntawm ntau yam khoom uas cov khoom muaj. Piv txwv li, 'S' qhia 'Structural'. Loosely, uas txhais tau hais tias cov qauv hlau los yog hlau. Lub '235' qhia tias lub zog tawm los hauv MPa (megapascals hauv N / mm²) ntawm lub thickness ntawm 16 hli. Qhov no yog tus nqi tseem ceeb vim tias sai li sai tau thaum lub zog tensile ntawm 235 megapascals mus txog, cov hlau yuav pib ntws, ua rau cov yas deformation mus tas li. Cov npe hlau feem ntau muaj ntau cov lus xaus uas hais txog cov khoom thiab cov txheej txheem tsim khoom, piv txwv li: 'J2' 'K2' 'C' 'Z' 'W' 'JR' 'JO' 'N' ntawm 'NL' 'Q' ntawm 'QL' thiab 'M' ntawm 'ML'.

Ob leeg I-beam thiab H-beam yog ntau yam thiab tuaj yeem siv rau ntau yam kev siv.
Lawv yog ob qho tib si structural steel beams uas tau tsim los pab txhawb rau cov tsev thiab lwm yam qauv.
Qhov sib txawv tseem ceeb ntawm ob hom kab teeb no yog lawv cov duab. Ib qho "I" beam muaj ib daim duab peb sab cross-section, thaum lub "H" beam muaj ib lub duab plaub (li no lub npe).
Lwm qhov sib txawv ntawm lawv yog tias "H" beam feem ntau ntev dua "I" beam ntawm qhov loj me thiab qhov hnyav. Qhov no txhais tau hais tias H-beam yuav siv ntau qhov chaw thaum ntsia, tab sis nws kuj muaj zog ntau dua thaum nqa cov khoom hnyav dhau qhov ntev lossis ntev; whereas I-beam tej zaum yuav zoo dua rau kev tuav cov khoom me me ntawm qhov luv luv luv vim nws muaj zog ntxiv (tsawg dua).
Raws li qhov tshwm sim, H beams feem ntau suav hais tias yog qhov ruaj khov dua li kuv cov kab teeb vim lawv qhov hnyav dua thiab tawv. Txawm li cas los xij, muaj ntau qhov sib txawv uas tuaj yeem cuam tshuam lub nqaj lub zog thiab kev ua tau zoo, nrog rau nws cov txheej txheem tsim khoom, muaj pes tsawg leeg, thiab tsim. Thaum kawg, nws yog nyob ntawm ib tus kws tshaj lij thiab cov neeg tsim qauv xaiv cov kab teeb uas zoo tagnrho rau ib lub hom phiaj.
