S235JR steel yog siv tau zoo hauv kev tsim kho rau cov khoom siv dav dav xws li kab teeb, kab, thiab kev txhawb nqa hauv cov tsev thiab txuas hniav, vim nws cov weldability zoo, lub zog tsim nyog (235 N / mm² yield), ductility, thiab tus nqi -effectiveness rau lub teeb- mus rau - nruab nrab loads rau cov nqi, {{1} } tej yaam num xav tau yooj yim fabrication thiab txhim khu kev qha kev ua tau zoo qhov twg muaj zog heev tsis yog lub hauv paus kev txhawj xeeb. Nws kuj tseem zoo rau cov kav hlau, cov ncej, thiab kev tsim vaj tsev ua haujlwm zoo li khaws cov phab ntsa.
General Structure Cheebtsam
Kab thiab kab: S235JR steel feem ntau yog siv rau fabricating txhua kab thiab kab hauv qis - mus rau - nruab nrab - nce vaj tse. Nws lub zog tawm los ntawm 235 MPa (txog li 16 - hli -} cov ntu tuab) muab cov khoom thauj txaus - cov kabmob muaj peev xwm los txhawb lub tsev cov khoom tuag (xws li qhov hnyav ntawm cov khoom siv hauv tsev) thiab cov khoom nyob (xws li qhov hnyav ntawm cov neeg nyob, rooj tog, thiab khoom siv). Lub formability kuj zoo ntawm S235JR tso cai rau kom yooj yim shaping ntawm cov Cheebtsam kom tau raws li tus tsim yuav tsum tau ntawm cov tsev sib txawv.
Ru tsev Trusses: Hauv cov txheej txheem vov tsev, S235JR steel tuaj yeem siv los tsim trusses. Cov hlau lub zog - mus rau - qhov hnyav piv ua rau nws muaj peev xwm tsim tau loj - span ru tsev trusses uas tuaj yeem npog thaj chaw dav yam tsis tas yuav muaj kev txhawb nqa nruab nrab ntau dhau. Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv industrial cov tsev, warehouses, thiab sports arenas.
Tsis yog - Load - Bearing Elements with Added Strength
Bracing Systems: S235JR tuaj yeem siv rau bracing ntsiab hauv ib lub tsev qauv. Cov braces no pab tiv thaiv lub zog sab nraud xws li cua thiab seismic loads, txhim khu kev ruaj ntseg ntawm lub tsev. Lawv lub zog muaj zog heev tso cai rau lawv hloov cov zog no mus rau lub hauv paus, ua kom lub tsev muaj kev ncaj ncees thaum huab cua huab cua lossis cov xwm txheej seismic.
Muab faib Frames: Hauv kev muab faib sab hauv, S235JR steel tuaj yeem siv los tsim cov kab sib faib. Thaum cov kev faib tawm no yuav tsis dais lub ntsiab ntawm cov qauv ntawm lub tsev, lub zog ntawm S235JR muab kev ruaj khov thiab muaj peev xwm los txhawb nqa cov khoom sib tw xws li phab ntsa ntub dej lossis vaj huam sib luag. Nws kuj tseem muaj kev tiv thaiv hluav taws zoo dua piv rau qee yam tsis yog - cov khoom siv hlau muab faib.
Kev sib txuas thiab kev sib koom ua ke
Bolts thiab Welded Connections: S235JR steel feem ntau yog siv los tsim cov bolts thiab cov khoom siv rau kev sib txuas welded. Cov hlau zoo weldability thiab mechanical zog ua rau nws tsim nyog rau kev tsim kom muaj zog thiab txhim khu kev qha kev sib txuas ntawm cov qauv sib txawv. Siab - lub zog bolts ua los ntawm S235JR tuaj yeem ruaj ntseg txuas kab teeb rau txhua kab lossis lwm cov tswv cuab, ua kom muaj kev ncaj ncees tag nrho.
Ua ntej - fabricated Construction Elements
Modular Tsev Cheebtsam: S235JR steel yog zoo tagnrho rau ua ntej - fabricated modular tsev Cheebtsam. Cov khoom siv no tuaj yeem tsim tawm ntawm - qhov chaw hauv qhov chaw tswj hwm lub Hoobkas thiab tom qab ntawd thauj mus rau qhov chaw tsim kho kom yooj yim sib dhos. Qhov zoo sib xws thiab lub zog ntawm S235JR xyuas kom meej tias cov khoom ua ntej - fabricated ua tau raws li cov qauv tsim nyog. Piv txwv li, cov chav da dej modular, chaw ua haujlwm pods, lossis cov thawv ntim khoom ua los ntawm S235JR steel tuaj yeem yooj yim ua ke rau hauv ib lub tsev qauv.
Cov qauv ib ntus
Scaffolding thiab Shoring: S235JR steel feem ntau siv rau hauv kev tsim kho ntawm scaffolding thiab shoring systems. Scaffolding muab lub platform ua haujlwm nyab xeeb rau cov neeg ua haujlwm tsim kho thaum lub sijhawm tsim kho, kho dua tshiab, lossis kho. Lub zog ntawm S235JR tso cai rau lub scaffolding los txhawb qhov hnyav ntawm cov neeg ua haujlwm, cov cuab yeej, thiab cov khoom siv hauv tsev. Shoring systems, ntawm qhov tod tes, yog siv los txhawb kev khawb lossis cov qauv tsis ruaj khov thaum tsim kho. S235JR steel shoring Cheebtsam tuaj yeem tiv taus cov av siab thiab lwm yam kev thauj khoom, ua kom muaj kev nyab xeeb ntawm qhov chaw tsim kho.
Puas yog S235JR sib npaug rau A36?
Lo lus "235" yog hais txog qhov tsawg kawg nkaus yield zog (MPa) rau steel thickness tsawg dua 16 hli. Lub "JR" qhia txog lub zog-txog qib zoo ntawm Charpy impact test (27 J, 20℃kub). ASTM A36 cov khoom sib npaug rau cov hlau S235JR.
S235JR steel qib yog dab tsi?
S235JR yog cov khoom siv dav dav, tus nqi - zoo, tsis yog - alloy structural steel (EN 10025 tus qauv) paub zoo weldability thiab formability, qhia los ntawm nws qhov tsawg kawg nkaus 235 MPa yield zog (S) thiab 27 Joule cuam tshuam lub zog ntsuas ntawm chav tsev kub (JR), ua rau nws tsim nyog rau kev siv lub tshuab, kev siv lub tshuab, thiab kev tiv thaiv corrosion. tiv as nws tsis yog inherently stainless.
JR sawv cev rau dab tsi hauv S235JR?
S235JR: Ib hom hlau uas nquag siv, S235JR paub txog nws qhov weldability, machinability, durability, thiab hnav- ua haujlwm. Nws cov lus "JR" qhia tias nws qhov cuam tshuam tsawg kawg nkaus yog 27 joules thiab nws tau dhau los ua qhov kev ntsuam xyuas ntawm 20 degree.
