Dab tsi yog H-Beam Thiab I-Beam
H-Beam yog dab tsi?
H-beamyog cov khoom siv pob txha engineering nrog kev ua haujlwm siab load-bearing efficiency thiab lub teeb yuag tsim. Nws yog tshwj xeeb tshaj yog haum rau niaj hnub steel qauv nrog loj spans thiab siab loads. Nws cov txheej txheem tshwj xeeb thiab cov cuab yeej zoo yog tsav tsheb engineering technology innovation hauv kev tsim kho, txuas hniav, lub zog, thiab lwm yam.
I-Beam yog dab tsi?
Kuv-beamyog ib qho kev lag luam unidirectional dabtsi yog khoov cov khoom siv. Vim nws cov nqi qis thiab kev ua haujlwm yooj yim, nws tau siv dav hauv cov xwm txheej xws li cov kab teeb theem nrab hauv cov tsev thiab kev txhawb nqa txhua yam. Txawm li cas los xij, nws tsis zoo rau H-nqaj nyob rau hauv torsional tsis kam thiab ntau qhov kev taw qhia load-bearing, thiab nws cov kev xaiv yuav tsum nruj me ntsis raws li cov neeg siv khoom xav tau.
Qhov txawv ntawm H-Beam thiab I-Beam
Qhov tseem ceeb sib txawv
H-Beam: Cov flanges (sab sauv thiab sab kab rov tav) ntawm H-nqaj yog sib npaug thiab ntawm cov tuab tuab, tsim ib qho square "H"-zoo li tus ntoo khaub lig-section. Lawv muaj kev khoov zoo heev thiab torsional tsis kam, ua rau lawv haum rau cov tub ntxhais cov kabmob thauj khoom.
Ib-Beam: Cov flanges ntawm I-beam yog nqaim nyob rau sab hauv thiab dav sab nraud, nrog txoj kab nqes (feem ntau 8% mus rau 14%). Lawv muaj qhov "Kuv"-zoo li tus ntoo khaub lig-section, tsom rau unidirectional dabtsi yog khoov tsis kam thiab kev lag luam, thiab feem ntau yog siv rau cov khoom me me ntawm cov kab teeb.
Kev sib piv ntxaws
H-Beam:H-zoo li tus hlauyog ib lub thawv torsion-resistant tsim los ntawm uniformly dav thiab tuab parallel flanges thiab ntsug webs. Nws muaj cov khoom siv kho tshuab dav dav (khoov zoo heev, torsion, thiab siab ua haujlwm), tab sis nws cov nqi kuj yog siab heev. Nws yog tsuas yog siv nyob rau hauv core load-bearing scenarios xws li high-sawv tsev kab, loj-span Hoobkas ru tsev trusses, thiab hnyav crane beams.
Ib-Beam:Kuv-beamstxuag cov ntaub ntawv thiab txo cov nqi ua tsaug rau lawv cov flange slope tsim. Lawv ua tau zoo heev thaum raug unidirectional dabtsi yog khoov, tab sis muaj zog torsional tsis kam. Lawv tsim nyog rau cov khoom thauj me me, cov khoom nruab nrab xws li lub Hoobkas theem nrab kab teeb, cov cuab yeej txhawb nqa, thiab cov qauv ib ntus. Lawv yog qhov tseem ceeb ntawm kev daws teeb meem kev lag luam.
Daim ntawv thov scenarios ntawm H-Beam thiab I-Beam
H-Beam:
1. Super-siab cov tsev (xws li Shanghai Ntauwd) – dav-flange kab tiv thaiv av qeeg thiab cua torque;
2. Loj-span industrial cog ru tsev trusses - siab dabtsi yog khoov kuj txhawb nqa hnyav cranes (50 tons thiab nce) thiab ru tsev khoom;
3. Lub zog tsim hluav taws xob - thermal fais fab nroj tsuag boiler steel thav duab tiv taus siab thiab kub siab, thiab cua turbine yees muab kev txhawb nqa sab hauv los tiv thaiv cua vibration;
4. Hnyav-duty choj - trusses rau hla hiav txwv choj tiv thaiv tsheb dynamic loads thiab seawater corrosion;
5. Heavy machinery - mining hydraulic kev txhawb nqa thiab nkoj keels xav tau lub siab-torsion thiab qaug zog-resistant matrix.
Ib-Beam:
1. Muaj lub tsev ru tsev purlins - Angled flanges zoo txhawb xim-coated steel daim hlau (spans <15m), nrog rau tus nqi 15%-20% qis dua H-beams.
2. Cov khoom siv sib zog txhawb nqa - Conveyor lem thiab me me platform thav ntawv (load muaj peev xwm <5 tons) ua tau raws li qhov yuav tsum tau ua kom zoo li qub.
3. Cov qauv ib ntus - Kev tsim kho scaffolding beams thiab exhibition shed txhawb txhua kab sib dhos sai thiab disassembly nrog cov nqi-zoo.
4. Cov txuas hluav taws xob tsawg - Kev txhawb nqa tsuas yog cov nqaj hlau txuas ntawm txoj kev nyob deb nroog (spans <20m) leverage lawv cov nqi khoov zoo.
5. Machinery foundations - Cov cuab yeej siv lub hauv paus thiab cov tshuab ua liaj ua teb siv lawv cov tawv tawv-rau-qhov hnyav.
