Dab tsi yogHollow Structural Sections?
Hollow Structural Sections (HSS) sawv cev rau cov chav kawm ntawm cov hlau profiles feem ntau ua los ntawm cov hlau txias, zoo li tus tubular configurations.Daim ntawv tshwj xeeb no ua rau muaj qhov qhib, tsis muaj ntug khiav raws tag nrho qhov ntev ntawm cov hlau bar, tau txais lawv cov monikers lwm qhov "box section" thiab "hollow section."Kev saws me nyuam ntawm HSS tau nce siab vim nws daim ntawv tuaj yeem yooj yim, ntau yam, thiab muaj kev ncaj ncees ntawm cov qauv, ua rau nws tshwj xeeb rau kev tsim thiab kev xav txog kev tsim qauv.
Hom Hollow Structural Sections:
Hollow Structural Sections feem ntau muaj nyob rau hauv peb lub ntsiab configurations: rectangular hollow sections (RHS), square hollow sections (SHS), and circular hollow sections (CHS).Txhua qhov sib txawv ntawm qhov hollow seem muaj qhov zoo sib xws, cov khoom, thiab kev siv.
1.Square Hollow Sections (SHS):
SHS muaj ib qho square cross-section thiab feem ntau yog siv rau hauv kev tsim cov qauv uas cov duab square nyiam lossis xav tau.Lawv feem ntau ua hauj lwm hauv lub tsev thav duab, txhawb cov kab, thiab lwm yam kev siv vaj tse.
2.Rectangular Hollow Sections (RHS):
RHS muaj ib lub voj voos kheej kheej thiab siv rau hauv cov xwm txheej uas cov duab plaub yog qhov tsim nyog.Zoo ib yam li SHS, RHS feem ntau yog siv hauv tsev thiab kev tsim kho rau cov khoom siv.
3.Circular Hollow Sections (CHS):
CHS muaj lub voj voos kheej kheej thiab feem ntau siv rau hauv cov ntawv thov uas lub voj voog zoo ib yam, xws li hauv kev tsim cov kab, ncej, thiab lwm yam qauv cylindrical.CHS paub txog nws cov khoom siv tau zoo hauv kev tiv thaiv torsional loads.
Hollow Structural Sections (HSS) hauv kev lag luam hlau khav theeb ntau yam tseem ceeb:
1.Kev siv ntau yam thoob plaws kev lag luam:
HSS tau pom dav dav rau nws lub peev xwm tshwj xeeb los tiv thaiv kev thauj khoom ntau dhau sijhawm ntev.Qhov no versatility ua rau nws nyiam cov khoom siv rau tej yaam num xav tau robust stability.Kev hloov pauv ntawm HSS tso cai rau nws siv nyob rau hauv ntau qhov chaw, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau tej yaam num uas yuav tsum tau muaj peev xwm tiv thaiv corrosive los yog puas.
2.High Load-Bearing Peev Xwm:
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm HSS yog nws lub peev xwm zoo tshaj plaws los tiv thaiv kev thauj khoom siab, ua rau nws muaj kev ntseeg siab rau kev siv cov qauv uas lub zog yog qhov tseem ceeb.
3.Broad Environmental Suitability:
HSS nthuav tawm qhov ua tau zoo nyob hauv ntau qhov chaw, tso cai rau nws siv hauv ntau qhov chaw.Cov yam ntxwv no ua rau nws tshwj xeeb tshaj yog haum rau tej yaam num raug corrosive los yog nyuaj tej yam kev mob.
