Basic Introduction To Steel Structure
Cov qauv hlau yog cov qauv tsim los ntawm cov khoom siv hlau thiab yog ib qho ntawm cov qauv tseem ceeb ntawm lub tsev. Cov qauv no tsuas yog tsim los ntawm cov kab hlau, steel kab, steel trusses thiab lwm yam khoom ua los ntawm steel seem thiab steel daim hlau, thiab txais kev tshem tawm xeb thiab xeb tiv thaiv txheej txheem xws li silanization, ntshiab manganese phosphating, dej ntxuav thiab ziab, thiab galvanizing. Welds, bolts lossis rivets feem ntau yog siv los txuas cov khoom lossis cov khoom. Vim nws lub teeb yuag thiab kev tsim kho yooj yim, nws tau siv dav hauv cov chaw tsim khoom loj, qhov chaw, cov tsev loj loj, txuas hniav thiab lwm qhov chaw. Cov txheej txheem steel yog yooj yim rau xeb. Feem ntau, cov qauv hlau yuav tsum tau xeb, galvanized lossis pleev xim, thiab khaws cia tsis tu ncua.
Cov yam ntxwv ntawm cov hlau yog siab zog, lub teeb yuag, zoo zuag qhia tag nrho nruj, thiab muaj zog tsis kam mus deformation. Yog li ntawd, nws yog tshwj xeeb tshaj yog haum rau lub tsev loj-span, super-siab thiab super-hnyav vaj tse; cov ntaub ntawv muaj zoo homogeneity thiab isotropy, thiab yog ib tug zoo tagnrho elastic lub cev, uas zoo tshaj plaws raws li lub hauv paus kev xav ntawm general engineering mechanics; cov khoom muaj zoo plasticity thiab toughness, muaj peev xwm loj deformation, thiab muaj peev xwm tiv taus dynamic loads zoo; lub sij hawm tsim kho yog luv; nws cov degree industrialization yog siab, thiab kev tsim tshwj xeeb nrog rau qib siab ntawm kev siv tshuab tuaj yeem nqa tawm.
Cov qauv hlau yuav tsum kawm cov hlau muaj zog heev kom txhim kho nws cov txiaj ntsig taw tes zog; Tsis tas li ntawd, cov hlau tshiab yuav tsum tau dov, xws li H-shaped steel (tseem hu ua dav flange steel) thiab T-shaped steel thiab corrugated steel daim hlau kom tau raws li cov kev xav tau ntawm cov qauv loj thiab cov tsev siab siab. .
Tsis tas li ntawd, muaj lub teeb steel qauv system tsis muaj thermal txuas hniav. Lub tsev nws tus kheej tsis muaj zog-npaum. Lub tshuab no siv cov khoom siv tshwj xeeb ntse los daws qhov teeb meem ntawm cov txuas hniav txias thiab kub hauv lub tsev; cov qauv truss me me tso cai rau cov kav dej thiab cov kav dej kom dhau los ntawm phab ntsa, uas yooj yim rau kev tsim kho thiab kho kom zoo nkauj.
