I-beams thiab H-beams siv ntau qhov sib txawv ntawm lub vev xaib rau flange qhov ntev. Txhua ntu ntu muaj nws qhov zoo, ua rau nws haum rau kev siv sib txawv.
I-shaped beams (los yog S-shaped beams, nyob ntawm seb cov neeg siv khoom xav tau) muaj nyias thiab siab webs thiab tuab flange uas ua haujlwm sab nraud ntawm txoj kab nqes ntawm 1:10. Cov flanges yog nqaim heev txheeb ze rau qhov siab ntawm lub vev xaib, yog li lawv cov ntu ntu yog lub peev "Kuv".
Thaum lawv muaj lub zog-rau-hnyav piv cov khoom thiab siab tiv thaiv kev khoov, lawv tsis muaj zog torsional. Lawv feem ntau siv nyob rau hauv kev txhawb nqa ncej thiab kab ntawm elevators, trailer, tramways thiab cranes.
Zoo li H-shaped steel, I-shaped steel kuj tau siv dav hauv cov tsev steel qauv thiab txuas hniav. Txawm li cas los xij, lawv cov spans me me, mus txog 100 ko taw, uas txhais tau tias yuav tsum muaj kev txhawb nqa ntxiv.
H-shaped steel muaj zog dua I-beam thiab yog qhov kev xaiv zoo tshaj plaws hauv kev ua haujlwm hnyav. Piv nrog rau I-beams, H-beams tuaj yeem tiv tsis tau tsuas yog thauj khoom ncaj qha tab sis kuj muaj cov khoom loj, yog li lawv cov nqi tag nrho cov nqi qis dua vim tias lawv tuaj yeem ncua ntev dua thiab siv kev txhawb nqa tsawg dua. kem.
