Lub tsev tau muab faib ua ob pawg: steel qauv thiab pob zeb ua qauv. Cov qauv hlau yog ua los ntawm ntu steel, steel phaj thiab steel yeeb nkab los ntawm vuam, bolting lossis riveting.
Engineering qauv, pob zeb.
Qauv: Nws yog ib qho kev tsim vaj tsev uas sib txuas ob yam khoom: steel thiab pob zeb los ua ib qho kev sib koom ua ke.
Yog li steel rau kev tsim kho
Feem ntau, nws tuaj yeem muab faib ua cov hlau rau cov qauv steel thiab cov hlau rau cov pob zeb muaj zog. Hlau rau steel qauv feem ntau suav nrog ntu steel, steel phaj, steel yeeb nkab, thiab steel rau pob zeb ua qauv
Main
Haum rau cov hlau thiab steel hlau.
1. Hlau rau steel qauv
1. Tshooj Hlau
Muaj ntau ntau hom steel hlau, uas yog cov khoom ntev steel nrog ib qho kev hla ntu thiab loj. Raws li nws cov duab cross-sectional, nws muab faib ua yooj yim thiab
Ob hom complex seem. Cov qub suav nrog lub voj voog
Hlau, square steel, tiaj tus hlau, hexagonal steel thiab lub kaum sab xis steel; Cov tom kawg suav nrog cov ntsia hlau, I-beams, H-beams, channel steels, windows
Ncej steel thiab tshwj xeeb-puab steel, thiab lwm yam.
2. Hlau phaj
Hlau phaj yog lub tiaj tiaj steel nrog qhov dav dav-rau-thickness piv thiab qhov loj ntawm qhov chaw. Raws li cov thickness, muaj nyias daim hlau (hauv qab 4 hli) thiab nruab nrab daim hlau (4mm-
20mm), tuab daim hlau (20mm-
Muaj plaub hom 60mm) thiab cov phaj tuab ntxiv (siab dua 60mm). Steel strips muaj nyob rau hauv steel phaj qeb.
3. Cov yeeb nkab steel
Cov yeeb nkab steel yog ib txoj hlua ntev ntawm cov hlau nrog ib qho hollow seem. Raws li nws cov duab sib txawv, nws tuaj yeem muab faib ua cov raj puag ncig, lub raj square, lub raj hexagonal thiab ntau yam tshwj xeeb zoo li seem.
Nto steel yeeb nkab. Raws li kev siv tshuab sib txawv
Nws tuaj yeem muab faib ua ob pawg: seamless steel yeeb nkab thiab welded steel yeeb nkab.
2. Hlau rau pob zeb ua qauv
1. Rebar
Steel bar yog hais txog cov ncaj los yog hlau qws-zoo li tus steel siv rau cov pob zeb muaj zog, uas yuav muab faib ua kub dov steel tuav (kub dov puag ncig bars HPB thiab kub dov ribbed
Rebar HRB), txias dov twisted steel bar
(CTB), txias-dov ribbed steel bar (CRB), cov txheej txheem xa khoom yog ncaj thiab coiled.
2. Hlau hlau
Hlau xaim yog lwm cov khoom ua haujlwm txias ntawm cov hlua hlau. Raws li cov duab sib txawv, nws tuaj yeem muab faib ua puag ncig steel hlau, tiaj tus hlau xaim thiab daim duab peb sab steel hlau. Hlau ntxiv rau kev ncaj qha
Ntxiv rau kev siv, nws kuj yog siv los tsim cov hlau hlau
hlua, steel xov thiab lwm yam khoom. Feem ntau siv nyob rau hauv prestressed pob zeb lug.
3. Hlau hlua
Steel strands yog tsuas yog siv rau prestressed qhob reinforcement.
