(1) High-nce steel qauv tshuab:
Raws li lub tsev qhov siab thiab kev tsim qauv, thav duab, thav duab txhawb nqa, lub tog raj kheej thiab cov ncej loj heev yog siv raws li. Nws cov khoom tuaj yeem ua los ntawm cov hlau, cov pob zeb ua kom muaj zog los yog steel tube pob zeb. Steel Cheebtsam yog lub teeb nyob rau hauv hnyav thiab zoo nyob rau hauv ductility. Lawv tuaj yeem ua los ntawm welded steel lossis dov steel. Lawv haum rau super-siab- cov tsev nce siab. Rigid reinforced qhob Cheebtsam muaj siab rigidity thiab zoo hluav taws kub. Lawv haum rau nruab nrab thiab siab -cov tsev nce siab lossis cov qauv hauv qab. Steel raj pob zeb yog ib qho yooj yim los tsim thiab tsuas yog siv rau cov kab ke.
(2) Spatial steel qauv technology:
Spatial steel qauv muaj lub teeb yuag, siab rigidity, zoo nkauj tsos thiab kev tsim kho ceev ceev. Spherical node flat grids nrog steel tubs li rods, multi-layer variable cross-section grids and grid shells are the most widely use structural type of spatial steel structures in my teb chaws. Lawv muaj qhov zoo ntawm qhov siab spatial rigidity thiab qis steel noj. Lawv muaj cov txheej txheem tsim, tsim thiab tshuaj xyuas thiab tuaj yeem ua tiav CAD. Ntxiv nrog rau cov qauv kab sib chaws, cov qauv spatial kuj suav nrog loj - ncua kev txuas cable thiab cable membrane cov qauv.
(3) Lub teeb steel qauv siv tshuab:
Nrog rau cov qauv qauv tshiab tsim los ntawm lub teeb xim hlau daim hlau ua los ntawm cov phab ntsa thiab lub ru tsev enclosure qauv. Lub teeb steel qauv system yog tsim los ntawm loj-section nyias-walled H-zoo li tus steel phab ntsa kab teeb thiab lub ru tsev purlins welded los yog dov los ntawm steel daim hlau nrog ib tug tuab ntawm 5 hli los yog ntau tshaj, round steel ua los ntawm saj zawg zog kev txhawb zog system thiab siab - lub zog bolt kev twb kev txuas. Cov kab sib nrug tuaj yeem yog los ntawm 6m mus rau 9m, qhov ntev tuaj yeem ncav cuag 30m lossis ntau dua, qhov siab tuaj yeem ncav cuag ntau tshaj kaum metres, thiab lub teeb dai tuaj yeem teeb tsa. Kev siv steel yog 20-30kg / m2. Tam sim no muaj cov txheej txheem tsim qauv tsim thiab kev tsim khoom lag luam. Cov khoom lag luam zoo yog qhov zoo, kev teeb tsa nrawm nrawm, qhov hnyav yog lub teeb, kev nqis peev tsawg, thiab kev tsim kho tsis txwv raws caij nyoog. Nws yog haum rau ntau lub teeb industrial nroj tsuag.
(4) Steel-concrete composite structure technology:
Lub nqaj thiab kab load-cov kabmob uas muaj cov hlau lossis cov kav hlau thiab cov khoom ua vaj tse yog cov hlau- cov qauv sib xyaw ua ke. Nws daim ntawv thov Scope tau nthuav dav hauv xyoo tas los no. Cov qauv sib xyaw muaj qhov zoo ntawm cov hlau thiab pob zeb, nrog rau tag nrho lub zog, zoo rigidity, thiab zoo seismic kev ua tau zoo. Thaum siv cov txheej txheem sab nrauv, nws muaj kev tiv thaiv hluav taws zoo dua thiab tiv thaiv corrosion. Composite structural Cheebtsam feem ntau tuaj yeem txo cov hlau siv los ntawm 15-20%. Composite pem teb slabs thiab steel tube ua vaj tse cov khoom tseem muaj qhov zoo ntawm tsawg los yog tsis muaj formwork, yooj yim thiab ceev kev tsim kho, thiab muaj peev xwm loj rau kev nce qib. Lawv haum rau cov kab teeb ci, kab thiab hauv pem teb slabs ntawm ntau- dab neeg lossis cov tsev siab siab nrog cov khoom loj, cov kab hauv tsev thiab cov slabs hauv pem teb, thiab lwm yam.
(5) High- lub zog bolt txuas thiab vuam tshuab:
High- lub zog bolts kis kev ntxhov siab los ntawm kev sib txhuam thiab muaj peb ntu: bolts, txiv ntseej thiab ntxhua khaub ncaws. High- lub zog bolt kev sib txuas muaj qhov zoo ntawm kev tsim kho yooj yim, hloov tau yooj yim dismantling, muaj peev xwm muaj peev xwm ua tau zoo, qaug zog tiv thaiv tus kheej thiab tus kheej -locking zog, thiab kev nyab xeeb siab. Lawv tau hloov riveting thiab ib feem welding nyob rau hauv engineering thiab ua lub ntsiab kev twb kev txuas txoj kev nyob rau hauv steel qauv tsim thiab installation. Rau steel Cheebtsam uas tsim nyob rau hauv lub rhiav, tuab daim hlau yuav tsum tau welded nrog tsis siv neeg multi- hlau arc vuam, thiab lub thawv kem partitions yuav tsum tau welded nrog melting nozzle electroslag vuam thiab lwm yam technologies. Thaum lub sij hawm ntawm - qhov chaw teeb tsa thiab kev tsim kho, semi- tsis siv neeg vuam tshuab thiab roj shielded flux-cored vuam hlau thiab tus kheej-shielded flux-cored vuam hlau tshuab yuav tsum tau siv.
(6) Steel qauv tiv thaiv technology:
Kev tiv thaiv cov qauv hlau muaj xws li kev tiv thaiv hluav taws, tiv thaiv corrosion, thiab tiv thaiv xeb. Feem ntau, kev tiv thaiv xeb yog qhov tsis tsim nyog tom qab kev kho hluav taws kub retardant txheej, tab sis kev tiv thaiv corrosion tseem tsim nyog nyob rau hauv cov tsev raug corrosive gases. Hauv tsev, muaj ntau yam hluav taws kub retardant txheej, xws li TN series thiab MC-10. MC-10 hluav taws kub retardant txheej muaj xws li alkyd enamel, chlorinated roj hmab xim, fluororubber xim, thiab chlorosulfonated xim. Thaum lub sij hawm tsim kho, cov txheej txheej tsim nyog thiab txheej txheej yuav tsum raug xaiv raws li cov qauv steel, cov kev xav tau ntawm kev tiv thaiv hluav taws, thiab kev xav tau ib puag ncig.
