Lub I Beam yog dab tsi?

I-beams, kuj hu uaH-beams, yog cov khoom siv dav tshaj plaws hauv kev tsim kho niaj hnub no. Lawv cov cim tseem ceebI- lossis H-puab hla ntumuab rau lawv cov peev xwm thauj khoom zoo heev thaum txo qis kev siv khoom, ua rau lawv zoo tagnrho rau ntau yam kev siv los ntawm cov tsev thiab cov choj mus rau kev tsim nkoj thiab cov qauv kev lag luam.

Hauv tsab xov xwm no, peb yuav kawm tob txog qhovhom I-beams, lawv covkev ua qauv ntawm lub cev, thiabvim li cas lawv thiaj tseem ceeb heevhauv kev tsim kho thiab cov haujlwm tsim kho vaj tse.

Ⅰ. Hom I-Beam thiab Lawv Cov Yam Ntxwv

Tsis yog txhua tus I-beams zoo ib yam. Muaj ntau yam kev hloov pauv raws li cov duab, qhov dav ntawm flange, thiab qhov tuab ntawm lub web. Txhua hom ua haujlwm sib txawv rau cov hom phiaj kev tsim kho nyob ntawm qhov xav tau ntawm kev thauj khoom, cov xwm txheej txhawb nqa, thiab cov qauv tsim.

1. Cov Qauv I-Beams (S-Beams)

Kuj tseem hu ua yooj yim xwbI-beams, tusS-beamyog ib qho ntawm cov qauv yooj yim tshaj plaws thiab ib txwm muaj. Nws feem ntau siv hauv North America thiab ua raws li ASTM A6/A992 cov lus qhia.

  • Cov Flanges Sib Npaug: I-beams muaj cov flanges sib luag (qee zaum me ntsis tapered).

  • Qhov dav ntawm Flange nqaimLawv cov flanges nqaim dua piv rau lwm cov hom flange beam dav.

  • Qhov Hnyav Muaj Peev XwmVim lawv cov flanges me dua thiab cov webs nyias dua, cov I-beams txheem yog qhov tsim nyog rau cov khoom thauj me dua thiab feem ntau yog siv rau hauv cov haujlwm tsim kho me dua.
