2. tšepe e chesang e chesang
2.1Ke-bama
I-beam steel joalo ka ha lebitso la eona le fana ka maikutlo, ke "I-shaped cross-section profiles", li-flanges tse ka holimo le tse ka tlaase lia fofa.
I-beam tšepe e arotsoe ka bophara bo tloaelehileng, bo bobebe le mapheo a mefuta e meraro, e nang le letšoao "mosebetsi" le palo ea ho boleloa. Ke nomoro efe e emelang bophahamo ba karolo ea palo ea lisentimitara. 20 le 32 ka holimo ho tloaelehileng I-beam, palo e tšoanang 'me e arotsoe ka mofuta oa a, b le a, b, c, botenya ba eona ba marang-rang le bophara ba flange ka ho latellana ke 2mm. joalo ka T36a hore bolelele ba karolo ea sefapano ke 360 ​​mm, botenya ba marang-rang ba sehlopha se tloaelehileng sa I-beam. Li-beams li lokela ho leka ho sebelisa botenya ba marang-rang ba thinnest ba mofuta oa mofuta oa a, e leng ka lebaka la boima ba eona bo bobebe, ha motsotsoana oa ho sesa oa inertia o batla o le moholo.
Motsotso oa inertia le radius ea gyration ea maballo a I-ka lehlakoreng le bophara e nyane haholo ho feta tse ka lehlakoreng la bophahamo. Ka hona, ho na le mefokolo e itseng ts'ebetsong, ka kakaretso e loketseng litho tse kobehang ka tsela e le 'ngoe.
3.kanale tšepe
Channel tšepe e arotsoe ka mefuta e 'meli ea tloaelehileng kanale tšepe le bobebe kanale tšepe. Mofuta oa tšepe oa mocha o nang le letšoao """" le palo ea ho boleloa." Ho tšoana le "beam", palo ea li-centimeters e boetse e emela bophahamo ba karolo ea "cross-section". Joalo ka [20 le Q [20] ka ho latellana, lebitsong la bophahamo ba karolo ea 200mm ea tšepe e tloaelehileng ea tšepe le tšepe e khanyang. Ke-bama.

 

4. angle tšepe
Angle tšepe e arotsoe ka mefuta e 'meli ea equilateral angle tšepe le ho se lekane angle tšepe.
Equilateral angle: maoto le matsoho a eona a mabeli a bolelele bo lekanang, mohlala oa eona o nang le letšoao "L" le bophara ba leoto x bophara ba maoto ka limilimithara, joalo ka L100x10 bakeng sa bophara ba 100mm, botenya ba maoto a 10mm equilateral angle.
Li-angles tse sa lekaneng: maoto a eona a mabeli a mahlakoreng a mabeli ha a lekane, mohlala o nang le letšoao "" le bophara ba maoto a malelele x bophara ba maoto a makhutšoane x bophara ba maoto ka limilimithara, joalo ka L100x80x8 bakeng sa bophara ba maoto a malelele a 100mm, bophara ba maoto a makhutšoane a 80mm, botenya ba 8mm bo sa lekanang.

 
5. H-beam(e phuthetsoe le ho chesoa)
H-beam e fapane le I-beam.
(1) bophara ba flange, kahoo ho bile le flange e pharaletseng I-beam e boletsoeng.
(2) Sebaka se ka hare sa flange ha se hloke ho ba le moepa, libaka tse ka holimo le tse ka tlaase li tšoana.
(3) ho tloha ka mokhoa oa kabo ea lintho tse bonahalang, I-beam cross-karolo ya thepa e haholo-holo concentrated ka ho web ho pota-pota, ho feta ho mahlakoreng a katoloso, ka tlaase ho tšepe, 'me phuthoa H-beam, thepa kabo tsepamisa maikutlo moeling oa karolo.
Ka lebaka la sena, litšoaneleho tsa H-beam cross-section ho hlakile hore li phahametse mosebetsi oa setso, mocha, angle le motsoako oa bona oa ho tšela, tšebeliso ea liphello tse molemo tsa moruo.
Ho ea ka maemo a hona joale a naha "hot rolled H-beam le karolo T-beam" (GB/T11263-2005), H-beam e arotsoe ka mekhahlelo e mene, e khethiloeng ka tsela e latelang: bophara ba flange H-beam - HW (W bakeng sa prefix ea Wide English), litlhaloso ho tloha 100mmx100mm ~ 400mmx40; flange e bohareng H-beam - HM (M bakeng sa sehlohlolong sa Senyesemane sa Bohareng), litlhaloso tse tsoang ho Specification ho tloha 150mmX100mm~600mmX300mm: Narrow Cui-edge H-beam - HN (N for Narrow English prefix); lerako le lesesaane la H-beam - HT (T for Thin English prefix). H-beam specification marking e sebelisoa: H le boleng ba bophahamo ba h boleng x bophara ba b boleng x boleng ba botenya ba web t boleng x boleng ba botenya ba flange t2 boleng bo boletsoeng. Joalo ka H800x300x14x26, ke hore, bolelele ba karolo ea 800mm, bophara ba flange ke 300mm, botenya ba marang-rang ke 14mm, botenya ba flange ba 26mm H-beam. Kapa o ile a bontša pele ka matšoao a HWHM le HN a re sehlopha sa H-beam, se lateloa ke "bolelele (mm) x bophara (mm)", joalo ka HW300x300, ke hore, bolelele ba karolo ea 300mm, bophara ba flange ba 300mm bophara ba flange H-beam.
6. T-beam
Sectional T-beam (Figure) e arotsoe ka mekhahlelo e meraro, khoutu e tjena: bophara ba flange karolo ea T-beam - TW (W bakeng sa Wide English hlooho); karolong ea flange ea T-beam - TM (M bakeng sa hlooho ea Middle English); moqotetsane flange karolo ea T-beam - TN (N bakeng sa Narrow English hlooho). Sectional T-beam ka H-beam e tsamaisanang le bohareng ba tepo e lekanang e arotsoe. Litlhaloso tsa Sectional T-beam tse tšoailoeng ka: T le bophahamo h boleng x bophara b boleng x botenya ba tepo t boleng x botenya ba flange t boleng. Tse kang T248x199x9x14, ke hore, bolelele ba karolo ea 248mm, bophara ba lepheo ke 199mm, botenya ba marang-rang ke 9mm, botenya ba flange ke 14mm T-beam. E ka boela ea sebelisoa le H-beam boemeli bo tšoanang, joalo ka TN225x200 ke hore, bophahamo ba karolo ea 225mm, bophara ba flange ea 200mm moqotetsane oa karolo ea T-beam.
