Sab hauv thiab sab nrauv ntawm cov flanges ntawm H-zoo li tus hlau yog sib npaug los yog ze rau thaum uas tig mus, thiab cov flange kawg yog nyob rau ntawm txoj cai kaum, li no lub npe parallel flange I-beam. Lub web thickness ntawm H-zoo li tus hlau yog me dua li ntawm qhov zoo tib yam I-beams nrog tib lub web qhov siab, thiab lub flange dav yog loj dua li cov zoo tib yam I-beams nrog tib lub web qhov siab, yog li nws kuj hu ua dav-ntug. Kuv-beam. Kev txiav txim siab los ntawm nws cov duab, seem modulus, lub sij hawm ntawm inertia thiab coj lub zog ntawm H-zoo li tus hlau yog ho zoo dua li qub I-beams ntawm tib chav tsev qhov hnyav. Siv hauv cov qauv hlau nrog cov kev xav tau sib txawv, nws qhia tau hais tias nws qhov kev ua tau zoo dua txawm tias nws dais lub sijhawm dabtsi yog khoov, siab load, lossis eccentric load. Nws tuaj yeem ua rau muaj peev xwm ua kom muaj peev xwm loj dua piv nrog cov kab hluav taws xob zoo tib yam thiab txuag 10% mus rau 40% ntawm cov hlau. H-zoo li tus hlau muaj flanges dav, nyias webs, ntau yam specifications, thiab saj zawg zog siv. Nws tuaj yeem txuag tau 15% mus rau 20% ntawm cov hlau thaum siv ntau yam truss qauv. Vim tias sab hauv thiab sab nrauv ntawm flange yog sib npaug thiab cov ntug xaus yog nyob rau ntawm txoj cai kaum, nws yog ib qho yooj yim los sib sau ua ke thiab ua ke rau hauv ntau yam, yog li txuag li ntawm 25% ntawm cov vuam thiab riveting ua hauj lwm, uas yuav ua tau zoo heev txhim kho kev tsim kho. ceev ntawm qhov project thiab shorten lub sij hawm tsim kho.
Vim yog qhov zoo saum toj no, H-shaped steel yog dav siv, feem ntau yog siv rau hauv: ntau yam kev tsim vaj tsev thiab kev tsim vaj tsev; ntau yam loj-span industrial nroj tsuag thiab niaj hnub high-sawv vaj tse, tshwj xeeb tshaj yog muaj cov nroj tsuag nyob rau hauv cov cheeb tsam uas nquag seismic kev ua si thiab high-temperature ua hauj lwm tej yam kev mob; yuav tsum tau loj txuas hniav nrog loj bearing muaj peev xwm, zoo cross-sectional stability thiab ntev ncua; khoom siv hnyav; txoj kev loj; nkoj ncej; kev txhawb nqa kuv; lub hauv paus kev kho mob thiab dam engineering; ntau yam tshuab Cheebtsam.
Muaj ntau yam khoom tshwj xeeb ntawm H-shaped steel, thiab cov txheej txheem kev faib tawm yog raws li hauv qab no. (1) Raws li qhov dav flange ntawm cov khoom, nws tau muab faib ua flange dav, nruab nrab flange thiab nqaim flange H-shaped steel. Lub flange dav B ntawm dav-flange thiab nruab nrab-flange H-zoo li tus hlau yog ntau dua lossis sib npaug ntawm lub vev xaib qhov siab H. Lub flange dav B ntawm nqaim-flange H-shaped steel yog kwv yees li ntawm ib nrab ntawm lub vev xaib qhov siab. H. (2) Raws li cov khoom siv, nws tau muab faib ua H-shaped steel kab, H-shaped steel kab, H-shaped steel piles, thiab tuab heev flange H-shaped steel beams. Qee lub sij hawm thaum uas tig mus rau sab channel steel thiab parallel flange T-shaped steel kuj muaj nyob rau hauv cov Scope ntawm H-shaped steel. Feem ntau, nqaim-flange H-puab steel yog siv los ua cov khoom siv nqaj, thiab dav-flange H-shaped steel yog siv los ua cov khoom siv. Raws li, nws tseem hu ua beam-hom H-shaped steel thiab kem-hom H-zoo li tus hlau. (3) Raws li txoj kev tsim khoom, nws tau muab faib ua welded H-shaped steel thiab dov H-shaped steel. (4) Raws li qhov loj me, nws tau muab faib ua loj, nruab nrab thiab me H-shaped steel. Feem ntau, cov khoom uas muaj lub vev xaib siab H siab tshaj 700mm yog hu ua loj, cov neeg uas muaj lub web qhov siab H ntawm 300 thiab 700mm yog hu ua nruab nrab, thiab cov khoom uas lub web qhov siab H tsawg dua 300mm yog hu ua me me. Thaum kawg ntawm xyoo 1990, lub ntiaj teb loj tshaj plaws H-shaped steel web muaj qhov siab ntawm 1200mm thiab flange dav ntawm 530mm.
