Lintlha tsa Bohlokoa ha ho Khethoa H Beam e Nepahetseng

Motheo oa khetho o qala ka ho tseba meroalo eo lehlaseli le lokelang ho e tšehetsa. Har'a tsena ke:

1. Meroalo e Shoeleng (Boima ba Kamehla ba Moaho ka Boona)

2. Mejaro e phelang (batho, thepa ea ka tlung, likoloi, lehloa, le tse ling)

3. Meroalo e matla (moea, matla a tšisinyeho ea lefatše)

Litsebi tsa boenjiniere ba meaho li sebelisa software ea tlhahlobo ea meaho kapa likhoutu tsa moralo (mohlala, AISC ho la US, Eurocode ho la Europe, kapa litekanyetso tsa GB Chaena) ho bala linako tsa ho kobeha, matla a ho kuta le meeli ea ho kheloha.

Bolelele ba Sekhahla le Maemo a Tšehetso

Li-span tse telele li hloka mahlaseli a nang le motsotso o moholo oa ho se tsitse ho fokotsa ho fapoha. Mohlala:

1. Lipalo tse khutšoane (ho fihlela ho 6-8m) khoebong e bobebe hangata li etsoa ka likarolo tse nyane tse bolelele ba ~ 150-200 mm.

2. Li-spans tse mahareng (maoto a 26-49) matlong a polokelo hangata li hloka mahlaseli a bolelele ba lisenthimithara tse 10-14.

3. Li-span tse kholo kapa merero e boima (marokho, liholo tse kholo tsa indasteri) li hloka likarolo tse 400 mm+ kapa limaraka tse teteaneng.

Kereiti ea Boitsebiso le Matla

Mefuta ea tšepe e sebelisoang khafetsa ke:

1.Lehlaseli la H la ASTM A36 / A572 / A992(Tekanyetso ea US, matla a tlhahiso a hakanyetsoang ke 250-345 MPa)

2.EN S235 / S275 / S355 H Beam(Mokgwa wa Yuropa)

3.GB Q235 / Q345 H Beam (tloaelo ea Sechaena)

Meedi e matla haholo (mohlala, Q345B kapa S355) e dumella dikarolo tse bobebe bakeng sa mojaro o tshwanang, e leng se fokotsang boima bohle ba thepa le ditjeo tsa motheo - sena se kgahla haholo dibakeng tsa tshisinyeho ya lefatshe kapa bakeng sa kaho e phahameng.

Litlhaloso tsa Boholo le Dintlha tsa Dintlha

Libalaka tsa H li khetholloa ka bolelele × bophara × botenya ba webe × botenya ba flange (metric) kapa botebo bo tloaelehileng + boima ka leoto (moemphera, mohlala, W8×40).

Boholo bo tsebahalang bo kenyelletsa:

1. Mosebetsi o bobebe: 100 × 100 mm ho isa ho 200 × 100 mm

2. Mosebetsi o mahareng: 250×250 mm ho isa ho 300×300 mm

3. Boima ba mosebetsi: 400×200 mm le ho feta

Kamehla sheba lichate tsa boholo bo tloaelehileng bakeng sa thepa ea likarolo (motsotso oa ho se sebetse hantle, modulus ea likarolo, boima ka mithara) ho lumellana le litlhoko tsa projeke.

Lintho tse Ikhethang ka Tikoloho le Morero

Ho hanyetsa mafome: Sebelisa tšepe e foreimisitsoeng, e pentiloeng, kapa e nang le mocheso o phahameng (mohlala, Corten) libakeng tse kantle kapa tse mongobo.

Ho tjheseletsa le ho bopeha ha yona: Netefatsa hore kereiti e tsamaisana le mekgwa ya ho tjheseletsa e sebediswang sebakeng seo.

Litšenyehelo le ho fumaneha ha tsona: Nahana ka ts'ebetso khahlanong le liketane tsa phepelo tsa lehae—tlhaloso e feteletseng e ka eketsa litšenyehelo ka 20–50%.

Rerisa Litsebi

Ho ngola khoutu ya pele ho ka sebedisa dikhalkhuleita tsa inthanete kapa ditafole tsa span, empa kgetho ya ho qetela e lokela ho netefatswa ke moenjiniere wa meaho ya nang le laesense. Boholo bo tlwaelehileng bo tla latela khoutu mme bo utlwahale hantle ka sebopeho – le ka mohla ha bo itshetlehe feela ka dipalopalo tse molaong.
