Ua ntej, txawm tias H-shaped steel yog qhov zoo tib yam lossis lub teeb, vim qhov siab thiab nqaim hla ntu ntu, lub sijhawm ntawm inertia ntawm ob lub tes tsho tseem ceeb ntawm ntu ntu yog qhov sib txawv heev. Yog li ntawd, nws feem ntau tsuas yog siv ncaj qha rau ntawm nws lub vev xaib. Cheebtsam raug rau hauv-dav hlau dabtsi yog khoov los yog muaj li ntawm lattice-type stress-bearing Cheebtsam. Nws tsis tsim nyog siv cov tswv cuab axial compression los yog cov tswv cuab uas yog perpendicular rau lub vev xaib dav hlau thiab khoov, uas txwv nws cov ntawv thov ntau yam.
Thib ob, H-shaped steel yog qhov ua tau zoo thiab kev lag luam txiav profile (lwm tus muaj xws li txias-tsim nyias-walled steel, profiled steel daim hlau, thiab lwm yam). Vim lawv cov duab sib dhos tsim nyog, lawv tuaj yeem ua rau cov hlau zoo dua thiab txhim kho nws lub peev xwm txiav. Sib txawv ntawm cov hlau zoo tib yam I-shaped, lub flange ntawm H-shaped steel yog dav, thiab sab hauv thiab sab nrauv feem ntau yog sib npaug, uas ua rau nws yooj yim rau siv lub zog siab screws los txuas rau lwm yam khoom. Nws qhov loj me yog qhov tsim nyog nrog cov qauv ua tiav, uas yooj yim rau kev tsim thiab xaiv.
Thib peb, cov flanges ntawm H-zoo li tus hlau yog tag nrho cov tuab tuab, nrog rau cov dov seem thiab cov seem sib xyaw ua ke ntawm peb daim hlau welded. I-beams yog tag nrho cov dov seem. Vim tias cov cuab yeej siv tsis zoo, cov npoo sab hauv ntawm flange muaj txoj kab nqes ntawm 1:10. Lub dov ntawm H-zoo li tus hlau yog txawv ntawm qhov zoo tib yam I-beam steel, uas tsuas yog siv ib txheej ntawm kab rov tav rollers. Vim tias nws cov flange yog dav thiab tsis muaj txoj kab nqes (los yog txoj kab nqes me me), nws yog ib qho tsim nyog yuav tsum tau ntxiv cov txheej txheem ntsug rau dov tib lub sijhawm. Yog li ntawd, nws cov txheej txheem dov thiab cov cuab yeej siv tau yooj yim dua li cov rolling mills. Qhov siab tshaj plaws ntawm dov H-zoo li tus hlau uas tuaj yeem tsim hauv Suav teb yog 800mm. Yog nws tshaj qhov siab,
