H-section steel yog ib hom kev txhim kho kev lag luam nrog high-efficiency profile nrog ntau qhov chaw faib qhov ntau dua thiab ntau dua qhov tsim nyog-qhov hnyav piv. Nws muaj npe vim nws seem yog tib yam li cov lus Askiv "H". Vim tias H-nqaj yog teem rau ntawm cov ces kaum ntawm txhua qhov chaw, H-Beam muaj qhov zoo ntawm qhov muaj zog thev taus, yooj yim siv, nqi txuag thiab lub cev nyhav nyob rau txhua txoj hau kev, thiab tau siv dav.
H-nqaj yog dab tsi?
Scope ntawm daim ntawv thov H-beam
H-section steel yog siv rau cov nqaj thiab sab cov neeg hauv cov khoom siv thiab kev ua haujlwm.
Steel Structural Rackets rau Industrial Buildings
Cov Hlau Pawg thiab Cov Txhawb Nqa ntawm Cov Tsev Kawm Ntawv Underground Engineering
Tus qauv ntawm cov khoom siv xws li Petrochemical kev lag luam thiab fais fais fab
Cov tswv cuab ntawm Long Span Steel Bridge
Nkoj thiab Machinery Manufacturing Lub Nruab Nrab Structures
Kev ciav hlau, lub tsheb, tsheb laij teb nkag
Chaw nres nkoj conveyor siv, kev kub ceev cov khauj khawm
H-section steel yog ib hom kev khwv nyiaj steel, uas yog siv rau kev lag luam, kev tsim kho, choj, roj drilling platform thiab lwm yam.
Kev taw qhia txog H-nqaj
H-beams raug muab faib ua H-kab thiab kub H-kab. Cov H-kab ntawv kub tau muab faib ua ntau H-kab hluav taws (HW) H-beams (HM) thiab voj fais fab H-beams (HN).
HW yog qhov sib npaug thiab qhov flange dav ntawm H-seem hlau; nws yog tsuas yog siv rau cov tub ntxhais hlau txhua kab hauv cov pob zeb khov pob zeb qauv txheem txhua kab, kuj paub zoo li steel hlau txhua; nws tsuas yog siv rau txhua kab hauv cov qauv hlau.
Qhov siab ntawm H-beam qhov siab mus rau flange dav yog kwv yees li 1.33 ~ 1.75 nyob rau hauv cov qauv steel: steel ncej txhua kab siv raws li kab teeb ci hauv cov txheej txheem cov txheej txheem xa mus rau kev tawm tsam; piv txwv, cov khoom siv khoom siv.
HN yog H-nqaj uas nws qhov siab ntawm qhov siab mus rau flange dav yog ntau dua los yog sib npaug 2. Nws yog tsuas yog siv rau kab teeb, thiab I-tus thawj yog sib npaug HN-nqaj.
Cov ntaub ntawv tseem ceeb ntawm H-seem hlau yog Q235B, SM490, SS400, Q345, Q345B, thiab lwm yam.
H-seem steel yog ib yam tshiab ntawm kev siv nyiaj txiag. Sib piv nrog cov I-seem steel, H-section steel muaj qhov zoo ntawm qhov seem loj module, lub cev nyhav thiab hlau txuag, uas tuaj yeem txo cov qauv hauv tsev los ntawm 30-40%. Vim hais tias nws cov hauv qab thiab cov ceg ntu thiab txoj cai kaum ntawm qhov kawg ntawm cov ceg, kev sib dhos thiab sib sau ua ke yuav txuag tau qhov haujlwm ntawm qhov khoom siv thiab qhov rais kom txog 25%. Nws yog siv rau hauv cov tsev loj (xws li cov tuam tsev, cov tsev siab, thiab lwm yam) uas yuav tsum muaj peev xwm loj thiab zoo rau kev sib tshooj, nrog rau cov txuas hniav, cov nkoj, kev tsav tsheb thiab kev thauj mus los, cov khoom siv phom, cov khoom siv , lub hauv paus teeb meem, thiab lwm yam.
H-seem steel yog ib hom kev khwv nyiaj txiag hlau nrog qhov zoo ntawm qhov kev sib tsoo khoom, uas yog tsim los ntawm qhov zoo ntawm I-seem steel. Tshwj xeeb, feem pua ntawm koog tsev kawm ntawv muaj npe tom qab tib yam li cov lus Askiv "H". Nws cov yam ntxwv yog raws li nram no:
Loj flange, loj lateral nruj. Qhov ua kom tsis muaj zog yog muaj zog, kwv yees li 5% - 10% siab dua I-nqaj.
Cov pob zeb flange muaj qhov sib luag rau txhua lwm yam, uas ua rau kev sib txuas, kev ua thiab kev yooj yim.
Muab piv rau cov hlau i-beam hlau, nws muaj tus nqi qis, muaj kev kub ntxhov, tsis tshua muaj kev ntxhov siab, tsis muaj ntaub qhwv nyiaj thiab khoom ntes, thiab txuag tau 30% ntawm kev tsim nqi steel hlau.
Nyob rau tib seem load, qhov nyhav ntawm cov hlau kub H H fais fab tuag yog txo los ntawm 15% - 20% piv nrog cov qauv khov hlau.
Muab piv nrog cov qauv ua pob zeb, H-steel hlau kub hnyav tuaj yeem ua rau thaj tsam ntawm kev siv li ntawm 6%, txo qhov hnyav ntawm tus qauv ntawm 20% mus rau 30%, thiab txo lub zog ntawm cov qauv tsim.
H-section hlau tuaj yeem ua tiav rau hauv T-section steel, thiab honeycomb beams tuaj yeem ua ke los ua ntau hom ntawv sib tawm, uas zoo heev raws li kev xav tau ntawm kev tsim vaj tse thiab kev tsim khoom.
