Kuv Beam yog dab tsi?

Kuv-beams, tseem hu ua H-beams, ua lub luag haujlwm tseem ceeb hauv thaj chaw ntawm kev tsim vaj tsev thiab kev tsim kho. Cov kab teeb no muab lawv lub npe los ntawm lawv qhov tshwj xeeb I lossis H-zoo li tus ntoo khaub lig-section, uas muaj cov kab rov tav hu ua flanges thiab cov ntsiab lus ntsug hu ua lub vev xaib. Kab lus no tsom mus rau delve rau hauv cov yam ntxwv, kev siv, thiab qhov tseem ceeb ntawm I-beams hauv ntau yam kev tsim kho.

Ⅰ.Type ntawm I-beams:

Ntau hom I-beams pom qhov sib txawv me me hauv lawv cov yam ntxwv, suav nrog H-piles, Universal Beams (UB), W-beams, thiab Wide Flange Beams. Txawm hais tias sib koom ib qho I-shaped cross-section, txhua hom muaj cov yam ntxwv tshwj xeeb uas ua raws li cov qauv tsim tshwj xeeb.

1. I-Beam:
•Parallel Flanges: I-beams muaj cov flanges thaum uas tig mus, thiab qee zaus, cov flanges no yuav taper.
• Cov ceg nqaim: Cov ceg ntawm I-beam yog nqaim dua piv rau H-piles thiab W-beams.
• Nyhav Tolerance: Vim lawv cov ceg nqaim, I-beams tuaj yeem tiv taus qhov hnyav dua thiab feem ntau muaj nyob rau hauv luv luv, txog li 100 ko taw.
•S-Beam Hom: I-beams poob rau hauv qeb ntawm S beams.
2. H-Piles:
•Heavy Design: Kuj hu ua bearing piles, H-piles zoo li I-beams tab sis hnyav dua.
• Wide Legs: H-piles muaj ob txhais ceg dav dua I-beams, pab txhawb lawv lub peev xwm hnyav hnyav.
•Equal Thickness: H-piles yog tsim los nrog sib npaug thicknesses thoob plaws txhua seem ntawm kab.
•Wide Flange Beam Hom: H-piles yog hom dav flange beam.
3. W-Beams / Wide Flange Beams:
• Wider Legs: Zoo ib yam li H-piles, W-beams muaj ob txhais ceg dav dua li tus qauv I-beams.
•Varying Thickness: Tsis zoo li H-piles, W-beams tsis tas yuav muaj qhov sib npaug ntawm lub web thiab flange thicknesses.
•Wide Flange Beam Hom: W-beams poob rau hauv qeb ntawm flange beams dav.

Ⅱ. Anatomy ntawm I-Beam:

Cov qauv ntawm I-beam yog tsim los ntawm ob lub flanges txuas nrog lub vev xaib. Cov flanges yog cov kab rov tav cov khoom uas dais feem ntau ntawm lub sijhawm khoov, thaum lub vev xaib, nyob nruab nrab ntawm cov flanges, tiv thaiv shear rog. Qhov kev tsim tshwj xeeb no qhia lub zog tseem ceeb rau I-beam, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv cov qauv.

Ⅲ. Khoom siv thiab kev tsim khoom:

I-beams feem ntau yog tsim los ntawm cov qauv hlau vim nws lub zog tshwj xeeb thiab ua haujlwm ntev. Cov txheej txheem tsim khoom suav nrog shaping cov hlau rau hauv qhov xav tau I-shaped cross-section los ntawm kev kub dov lossis vuam cov txheej txheem. Tsis tas li ntawd, I-beams tuaj yeem tsim los ntawm lwm cov ntaub ntawv xws li txhuas kom tau raws li qhov project tshwj xeeb.
