Kev taw qhia ceev ceev rau steel ncej hauv steel qauv.

Cov thav duab hlau hauv cov qauv hlau yog siv los ua "skeleton" lub hauv paus ntawm lub tsev, feem ntau muaj cov kab ntsug thiab kab rov tav, uas yog riveted, bolted, los yog welded ua ke nyob rau hauv ib daim phiaj rectilinear. Steel beams yog kab rov tav structural cov tswv cuab uas muaj peev xwm tiv taus loads tom qab rau lawv axis, thaum steel kab yog ntsug structural cov tswv cuab uas xa compressive loads. Daim phiaj ntawm kab teeb thiab kab no tuaj yeem siv los txhawb lub ru tsev, phab ntsa, pem teb, thiab lwm theem ntawm lub tsev.

Hauv cheeb tsam Wuhan, cov qauv steel feem ntau yog siv rau hauv siab -cov tsev siab, cov chaw tsim khoom, cov tsev khaws khoom, thiab cov tsev nyob. Lawv qhov zoo muaj xws li lub zog siab, qhov hnyav hnyav, qhov loj me, qhov yooj yim ntawm kev teeb tsa, ntawm - qhov chaw tsim khoom, siv sijhawm luv luv, kev tsim khoom ntau ntawm cov khoom siv rov ua dua, zoo cua thiab seismic tsis kam, thiab haum rau ntau txoj kev sib txuas.

 

Hom kev tsim steel ncej muaj xws li:

1. Cov khoom siv hlau tsoos: Cov khoom siv hlau yog tsim tawm - qhov chaw, txiav rau qhov ntev ntev, thiab welded ua ke.

2. Bolted steel: Cov khoom siv hlau yog tsim tawm ntawm -site thiab sib sau ua ke ntawm - qhov chaw siv bolts.

3. Lub teeb ntsuas steel: Zoo ib yam li cov qauv ntoo, siv cov khoom sib sib zog nqus hlau es tsis txhob siv cov ntoo.

4. Kub- dov steel feem ntau yog siv los tsim steel kab thiab kab. Cov no yog tsim los ntawm kev hla cov hlau kub ntawm cov chais loj uas deform cov hlau rau hauv cov duab uas xav tau, xws li "H" lossis "I" kab, kaum, thiab cov hlab.

Vim tias cov hlau softens ntawm qhov kub thiab txias, uas tuaj yeem ua rau cov txheej txheem tawg, lub thav duab yuav tsum muaj kev tiv thaiv hluav taws tshwj xeeb. Qhov no tuaj yeem ua tiav los ntawm kev thaiv cov hlau hauv masonry, pob zeb, lossis gypsum board, tab sis steel qauv hluav taws kub -cov txheej txheem siv ntau dua. Cov hlau tseem raug cuam tshuam rau corrosion nyob rau hauv cov huab cua ntub los yog marine ib puag ncig, yog li tiv thaiv - cov coatings coatings kuj tau siv.

Bracing yog ntxiv rau cov thav duab steel los txhim kho nws txoj kev ruaj ntseg tiv thaiv kev thauj khoom sab nraud (xws li cua loads thiab seismic rog). Cov tswv cuab bracing kuj feem ntau yog ua los ntawm cov qauv hlau thiab ua haujlwm zoo hauv ob qho tib si nro thiab compression.

Ntawm cov qauv txheej txheem no, lub portal thav duab, hauv nws daim ntawv yooj yim tshaj plaws, tau siv dav heev thiab muaj nyob hauv thaj tsam Wuhan.
