Kenyelletso ea Motheo ea H-Beam
1. Tlhaloso le Sebopeho sa Motheo
Li-flange: Lipoleiti tse peli tse bapileng, tse rapameng tsa bophara ba junifomo, tse nang le mojaro o ka sehloohong oa ho kobeha.
Web: Karolo ea setsi se otlolohileng se kopanyang li-flange, se hanyetsa matla a ho kuta.
TheH-beamLebitso la lona le tsoa ho "H" -joalo ka sebopeho sa likarolo tse fapaneng. Ho fapana leKe-bama(I-beam), li-flanges tsa eona li pharalletse ebile li bataletse, li fana ka khanyetso e kholo ho matla a ho kobeha le a torsional.
2. Likarolo tsa Tekheniki le Lintlha
Thepa le Maemo: Lisebelisoa tsa tšepe tse sebelisoang ka tloaelo li kenyelletsa Q235B, A36, SS400 (carbon steel), kapa Q345 (tšepe e tlaase ea alloy), e lumellanang le litekanyetso tsa machaba tse kang ASTM le JIS.
Boholo ba mefuta (litlhaloso tse tloaelehileng):
| Karolo | Sebaka sa parameter |
| Boemo ba webo | 100-900 limilimithara |
| Web botenya | 4.5–16 limilimithara |
| Bophara ba flange | 100-400 limilimithara |
| Botenya ba flange | 6–28 limilimithara |
| Bolelele | 12m e tlwaelehileng (e ka iketswang) |
Molemo oa matla: Moralo o pharaletseng oa flange o ntlafatsa kabo ea mojaro, 'me khanyetso ea ho kobeha e phahame ho feta 30% ho feta ea I-beam, e etsa hore e tšoanelehe bakeng sa maemo a boima.
3. Likopo tse ka Sehloohong
Mehaho ea Mehaho: Litšiea mehahong e phahameng le litšepe tsa marulelo lifekthering tse kholo li fana ka tšehetso ea mantlha ea ho jara.
Marokho le Mechini e boima: Li-crane girders le li-bridge girders li tlameha ho mamella meroalo e matla le khatello ea mokhathala.
Indasteri le Lipalangoang: Likamore tsa likepe, chassis ea terene, le metheo ea lisebelisoa li itšetlehile ka matla a tsona a phahameng le thepa e bobebe.
Lisebelisoa tse khethehileng: Lithupa tse hokahanyang tsa mofuta oa H lienjineng tsa likoloi (joalo ka enjene ea Audi 5-cylinder) li entsoe ka tšepe ea 4340 chromium-molybdenum ho mamella matla le lebelo le phahameng.
4. Melemo le Core Features
Moruo: Karolelano e phahameng ea matla ho boima e fokotsa tšebeliso ea thepa le litšenyehelo tse akaretsang.
Botsitso: Mehaho e metle e kopantsoeng ea flexural le torsional e etsa hore e tšoanelehe ka ho khetheha bakeng sa meaho e libakeng tse kotsing ea litšisinyeho tsa lefatše kapa tse tlas'a meroalo e matla ea moea.
Kaho e Bonolo: Likamano tse tloaelehileng li nolofatsa lihokelo ho meaho e meng (joalo ka welding le bolting), e khutsufatsa nako ea kaho.
Ho tšoarella: Ho chesa ho matlafatsa ho hanyetsa mokhathala, ho fella ka bophelo ba tšebeletso ea lilemo tse fetang 50.
5. Mefuta e khethehileng le mefuta e sa tšoaneng
Wide Flange Beam (Viga H Alas Anchas): E na le li-flange tse pharaletseng, tse sebelisetsoang metheo e boima ea mechine.
HEB Beam: Li-flange tse tšoanang tse matla, tse etselitsoeng lisebelisoa tse kholo (tse kang marokho a terene a lebelo).
Beam e Laminated (Viga H Laminada): Hot-rolled bakeng sa ntlafatso ea weldability, e loketseng bakeng sa liforeimi tse rarahaneng tsa mohaho oa tšepe.
Tšebeliso ea H-Beam
1. Mehaho ea Mehaho:
Kaho ea Sechaba: E sebelisoa mehahong ea bolulo le ea khoebo, e fanang ka tšehetso ea mohaho.
Indasteri Limela: Mabala a Hli ratoa ka ho khetheha bakeng sa limela tse telele le meaho e phahameng ka lebaka la bokhoni ba tsona bo botle ba ho jara le botsitso.
Mehaho e Phahameng: Matla a phahameng le botsitso ba marako a H a etsa hore e be khetho e nepahetseng bakeng sa libaka tse nang le tšisinyeho ea lefatše le libaka tse nang le mocheso o phahameng.
2. Boenjiniere ba Borokho:
Marokho a Maholo: Lifate tsa H li sebelisoa ka har'a marako le litšiea tsa marokho, li finyella litlhoko tsa li-spans tse kholo le matla a phahameng a ho jara.
3. Liindasteri tse ling:
Thepa e boima: Li-beams tsa H li sebelisetsoa ho tšehetsa mechine e boima le lisebelisoa.
Litsela tse kholo: E sebelisoa ka marokho le mehaho ea litsela.
Liforeimi tsa Sekepe: Matla le ho hanyetsa ha kutu ea mabala a H a etsa hore e tšoanelehe bakeng sa ho haha likepe.
Tšehetso ea Merafo:E sebelisoa meahong ea ts'ehetso bakeng sa merafo e ka tlas'a lefatše.
Ntlafatso ea Mobu le Boenjiniere ba Letamo: Lifate tsa H li ka sebelisoa ho tiisa metheo le matamo.
Lisebelisoa tsa Mochine: Mefuta e fapa-fapaneng ea boholo le litlhaloso tsa maballo a H le tsona li etsa hore e be karolo e tloaelehileng ea ho etsa mechine.
