Basic Introduction ntawm H-Beam
1. Kev txhais thiab cov qauv tsim
Flanges: Ob qho tib si, kab rov tav daim hlau ntawm qhov dav dav, coj tus thawj bending load.
Web: Qhov chaw ntsug ntsug txuas cov flanges, tiv thaiv shear quab yuam.
CovH-beamlub npe los ntawm nws "H"-zoo li tus ntoo khaub lig-sectional duab. Tsis zoo li ibKuv-beam(I-beam), nws cov flanges yog dav thiab tiaj tus, muab kev tiv thaiv ntau dua rau kev khoov thiab torsional rog.
2. Technical nta thiab Specifications
Cov ntaub ntawv thiab cov qauv: Cov khoom siv hlau feem ntau suav nrog Q235B, A36, SS400 (carbon steel), lossis Q345 (cov hlau tsis tshua muaj hlau), ua raws li cov qauv thoob ntiaj teb xws li ASTM thiab JIS.
Qhov ntau thiab tsawg (tus specifications):
| Ib feem | Parameter ntau yam |
| Web qhov siab | 100-900 hli |
| Web thickness | 4.5-16 hli |
| Flange dav | 100-400 hli |
| Flange thickness | 6-28 hli |
| Ntev | Txheem 12m (customizable) |
Lub zog kom zoo dua: Qhov dav flange tsim optimizes load faib, thiab khoov kuj yog ntau tshaj 30% siab tshaj li ntawm I-beam, ua rau nws haum rau hnyav-load scenarios.
3. Cov ntawv thov tseem ceeb
Architectural Structures: Cov kab hauv cov tsev siab siab thiab lub ru tsev trusses nyob rau hauv loj-span factories muab core load-bearing txhawb.
Cov choj thiab cov tshuab hnyav: Crane girders thiab choj girders yuav tsum tiv taus dynamic loads thiab nkees nkees.
Kev lag luam thiab kev thauj mus los: Nkoj decks, tsheb ciav hlau chassis, thiab cov khoom siv hauv paus cia siab rau lawv lub zog siab thiab lub teeb yuag.
Cov ntawv thov tshwj xeeb: H-hom txuas rods hauv tsheb cav (xws li Audi 5-lub tog raj kheej cav) yog forged los ntawm 4340 chromium-molybdenum steel kom tiv taus siab zog thiab ceev.
4. Qhov zoo thiab cov yam ntxwv tseem ceeb
Kev lag luam: Lub zog-rau-qhov hnyav piv txo cov khoom siv thiab tag nrho cov nqi.
Kev ruaj ntseg: Cov khoom sib xyaw ua ke zoo heev thiab torsional ua rau nws tsim tshwj xeeb rau cov tsev nyob hauv thaj chaw av qeeg lossis cov uas muaj cua daj cua dub.
Kev tsim kho yooj yim: Cov txheej txheem kev sib txuas ua kom yooj yim sib txuas rau lwm cov qauv (xws li vuam thiab bolting), ua kom lub sijhawm siv sijhawm luv.
Durability: Kub-dov txhim khu kev qaug zog, ua rau muaj kev pab cuam lub neej ntawm ntau tshaj 50 xyoo.
5. Hom tshwj xeeb thiab ntau yam
Wide Flange Beam (Viga H Alas Anchas): Nta dav flanges, siv rau hnyav machinery foundations.
HEB Beam: High-strength parallel flanges, tsim rau loj infrastructure (xws li high-speed rail choj).
Laminated Beam (Viga H Laminada): Kub-dov rau kev txhim kho weldability, haum rau txoj kev steel qauv thav duab.
Kev siv H-Beam
1. Kev tsim vaj tsev:
Kev tsim kho vaj tse: Siv nyob rau hauv cov tsev nyob thiab kev lag luam, muab kev txhawb nqa.
Cov nroj tsuag muaj: H-beamstshwj xeeb tshaj yog nrov rau cov nroj tsuag loj thiab cov tsev siab siab vim lawv cov peev txheej zoo heev thiab kev ruaj ntseg.
Tsev High-Rise: Lub zog siab thiab ruaj khov ntawm H-beams ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau thaj chaw av qeeg thiab qhov kub thiab txias.
2. Choj Engineering:
Cov choj loj: H-beams yog siv nyob rau hauv lub beam thiab kem qauv ntawm cov choj, ua tau raws li qhov yuav tsum tau ntawm loj spans thiab siab load-bearing muaj peev xwm.
3. Lwm yam kev lag luam:
Khoom hnyav: H-beams yog siv los txhawb nqa cov tshuab hnyav thiab khoom siv.
Txoj kev loj: Siv nyob rau hauv cov choj thiab cov vaj tse nyob.
Nkoj Ncej: Lub zog thiab corrosion kuj ntawm H-beams ua rau lawv tsim nyog rau nkoj tsim.
Kev them nyiaj yug kuv:Siv rau hauv kev txhawb nqa cov qauv rau cov mines hauv av.
Kev txhim kho av thiab Dam Engineering: H-beams tuaj yeem siv los txhawb lub hauv paus thiab cov dams.
Tshuab Cheebtsam: Ntau qhov ntau thiab tsawg thiab qhov tshwj xeeb ntawm H-beams kuj ua rau lawv muaj feem ntau hauv kev tsim tshuab.
