Hlau Txheej Txheem Hlau Txheeb Xyuas

Nrog kev nce qib ntawm kev tsim steel qauv choj kev tsim kho kev tsim kho tshuab, kuv lub teb chaws muaj cov khoom siv hauv kev thiab cov txheej txheem kev lag luam los txhawb cov qauv hlau txuas, txhawb kev tsim kho vaj tse steel txuas hniav xws li steel box girder, steel truss girder, thiab steel-concrete composite girder, thiab muab kev ua si tag nrho rau cov kev ua tau zoo ntawm cov qauv nqaj hlau. Cov. Lub sijhawm tam sim no yog lub sijhawm zoo los txhawb txoj kev tsim kho ntawm cov choj hlau txuas thiab txhim kho kev ua tau zoo ntawm kev tsim kho choj, nrog rau qhov kev ntsuas tseem ceeb los txhawb kev hloov pauv thiab txhim kho kev lag luam steel.

Qhov zoo ntawm cov qauv hlau txuas hniav:

Cov qauv hlau muaj qhov zoo ntawm lub teeb yuag, kev ua haujlwm zoo seismic, kev lag luam siab thiab kev sib sau ua ke, thiab rov ua haujlwm dua.

Nrog kev siv ntawm kev hla qhov loj ntawm cov txuas hniav, kev siv ntau ntawm kev siv hlau cov tsev yog ib qho xwm txheej uas tsis pom tseeb rau kev txhim kho yav tom ntej ntawm kuv lub teb chaws' s thauj cov tsheb thauj mus los.

Qhov tsis zoo ntawm cov qauv hlau txuas:

Lub tsev steel qauv raug tus nqi siab dhau;

Kev txhim kho corrosion tsis txaus, thiab lwm yam.

Tus nqi ntawm tus choj tsim yuav tsum xav txog ntau yam xws li tus nqi tsim kho, kev nyab xeeb thiab kav ntev, kev tswj hwm thiab txij nkawm. Cov qauv ntoo choj muaj qhov hnyav hnyav dua, uas txuag cov nqi ntawm cov substructure. Nyob rau tib lub sijhawm, kev tsim kho sai dua thiab kev tsim kho lub sijhawm luv.

Cov teeb meem ntawm kev txhim kho tsis txaus xeb ntawm cov qauv hlau muaj peev xwm daws tau los ntawm kev pleev xim ntev ntev kev ua haujlwm ntawm cov tshuaj tiv thaiv anticorrosive thiab siv huab cua steel.

Tag nrho cov qauv hlau suav nrog lub thawv steel girder thiab steel truss girder.

Cov hlau-pob zeb ua ke sib xyaw ua ke muaj xws li: steel phaj puas nqaj choj, steel lub thawv puas nqaj choj, thiab corrugated steel web choj.

Cov kab hlau truss muaj ntau yam zoo, xws li siab zog, cov khoom tsis sib xws, zoo plasticity thiab toughness, thiab weldability zoo.

Cov nta ntawm hlau truss:

Vim tias cov hlau muaj ntau qhov zoo xws li lub siab muaj zog, cov khoom siv tsis zoo, zoo yas thiab tawv, thiab zoo weldability, txuas hniav tsim ntawm hlau muaj cov yam ntxwv li nram no:

(1) Muaj peev xwm zoo leaping. Vim lub zog muaj zog ntawm cov hlau, qhov chaw hla ntawm cov nqaj hlau sib txuas me dua li cov uas muaj cov pob zeb tiv thaiv nyob rau hauv tib qho kev thauj khoom-kev muaj peev xwm, yog li cov choj hlau muaj qhov hnyav sib dua thiab tsim nyog rau kev tsim cov txuas hniav ntev.

(2) Feem ntau tsim nyog rau kev lag luam kev lag luam. Hlau choj txuas feem ntau ua tiav los ntawm cov khoom siv tshwj xeeb hauv cov chaw ua haujlwm tshwj xeeb, thiab tsis txwv rau lub caij nyoog. Kev ua thiab kev tsim tawm nrawm yog nrawm, qhov ntsuas siab yog siab, thiab qhov zoo yog yooj yim los tswj, yog li cov neeg lag luam qib siab yog qhov siab.

(3) Yooj yim thauj mus los. Vim tias qhov hnyav sib xws ntawm cov choj choj Cheebtsam, nws yooj yim rau kev thauj mus los hauv lub tsheb tshwj xeeb tshaj yog nyob rau thaj chaw roob nrog kev tsheb tsis yooj yim.

(4) Kev hloov kho sai heev. Cov choj choj ua ke tau yooj yim sib dhos nrog cov qauv cantilever kev tsim kho, ua tiav cov khoom siv tau, thiab cov txheej txheem los ua ke yog cov laus.

(5) Cov kauj hlau ua haujlwm yooj yim kho thiab hloov.

(6) Cov hlau tsis yooj yim rau xeb, yog li tus nqi saib xyuas ntawm tus choj steel yog siab. Tsis tas li ntawd, cov choj hlau yuav tsum tua hluav taws, thiab lub suab nrov nrov thaum lub tsheb ciav hlau hla dhau, yog li nws tsis tsim nyog los tsim cov choj hlau hla hauv cov chaw nyob hauv nroog.

Lub thawv steel girder, tseem hu ua steel box girder, yog cov qauv siv dav dav hauv kev txuas ntev ntawm cov choj. Feem ntau siv rau ntawm cov qhov txuas loj loj, nws hu ua steel box girder vim nws zoo li lub thawv.

Lub thawv steel girder feem ntau yog tsim los ntawm kev ua haujlwm vuam tag nrho cov phaj saum toj, hauv qab phaj, web, sab nraud hloov chaw, muab faib ntev thiab txhav txhav. Sab saum toj phaj yog pob orthotropic choj lawj muaj li ntawm npog npog phaj thiab ntu ntev stiffeners.

Lub thawv steel girder yog cov qauv txheej txheem feem ntau siv hauv engineering. Txhawm rau kawm qhov sib cuam tshuam ntawm qhov sib nrug ntawm transverse diaphragms ntawm kev sib pauv ntawm qhov yooj yim txhawb nqa lub thawv steel girder nyob rau hauv kev nkag siab yooj yim, qhov yooj yim txhawb nqa steel lub thawv girder nrog cov sib txawv ntawm cov transverse diaphragms tau tsim los sib piv nws cov txiaj ntsig sib txawv thiab nruj torsion effect hauv qab kev thauj khoom, qhov hloov nkhaus ntawm qhov siab tshaj plaws cuam tshuam nrog cov naj npawb ntawm diaphragms tau. Concentrated load yog thov rau sab saum toj ntawm lub thawv girder web, thiab nws tau saws raws li plaub yam kev ua haujlwm ntawm kev sib cais, txhav torsion, zooj thaum khoov thiab eccentric load. Cov qauv ntawm load decomposition yog xam.

Cov hlau-pob zeb ua ke sib xyaw ua ke yog tus choj ua lub pob zeb rau lub viav vias pob zeb ua rau cov pob zeb ua pob zeb ua pob zeb thiab cov nqaj nqaj hlau ua ua los ntawm cov qauv hlau.

Cov khoom muaj txiaj ntsig: ua kom siv tag nrho ntawm cov khoom siv zoo ntawm cov hlau thiab pob zeb. Pob zeb ua kev txhim kho qhov ruaj khov ntawm cov nqaj hlau.

Cov txiaj ntsig zoo: txo qhov siab ntawm tus qauv, nce qhov kev nruj ntawm cov qauv, thiab txo qhov deflection ntawm tus qauv hauv qab load.

Kev tsim kho yooj yim: kev tsim khoom hauv chaw tsim khoom, ua haujlwm siab rau kev teeb tsa, kev tsim kho tus nqi qis, thiab kev tsim kho sai.

Kev tiv thaiv ib puag ncig thiab txuag hluav taws xob: Ib qho tseem ceeb txo cov kev siv MAAs thiab txo qhov kuab paug ib puag ncig.

Qhov tsis zoo: Muaj qhov tsis muaj zog ntawm torsional tsis muaj zog thiab cov kev siv me me.

Shandong Hanpu Machinery IndustrialCo., Ltd. yog lub chaw tsim khoom hluav taws xob tsim hluav taws xob kev sib xyaw ua ke R& D, ntau lawm thiab muag khoom. Nws cov khoom tseem ceeb: hluav taws xob shear ciaj ntswj, hluav taws xob hluav taws xob ciaj ntswj, cov khoom siv ntsia hlau ntsia lub rooj sib tsoo, cov kab hluav taws xob axial lub zog, ntsuas lub zog axial thiab lwm yam Tom qab ntau tshaj 20 xyoo ntawm kev tsim kho tshiab thiab kev txhim kho, lub tuam txhab tam sim no muaj 62 ev kawj ntawm chaw ua si thiab 30,000 square metres ntawm kev tsim khoom thiab kev tshawb nrhiav thiab kev cob qhia ua haujlwm. Nws tau qhia ntau ntawm cov khoom lag luam siab kawg ua hauv Switzerland, Lub Tebchaws Yelemees, thiab Nyij Pooj, thiab tau dhau los ua cov khoom siv hluav taws xob ntau hauv cov hluav taws xob hauv Suav.
