Cov txheej txheem tsim kho thiab sib dhos cov ntsiab lus ntawm bailey truss

Bailey nqaj, nws tau sib dhos los ntawm bailey truss girder, feem ntau yog txuas rau cov tswv cuab, nrog cov ntsia hlau ruaj khov.

Daim ntawv thov: kev txhim kho nrawm, kev txav mus los siab, siv sijhawm ua rog rau dej thiab pob zeb teeb tsa cov choj yooj yim, tam sim no siv rau kev tsim vaj tsev, xws li gantry crane, kev tsim kho vaj tsev, kev tsim choj choj, thiab lwm yam.

Cov yam ntxwv: nqaj nqaj nqaj nrawm, nyob hauv ntau kab nrum-nyob rau hauv-kab teeb hla txoj kev loj thiab dej, muab qhov yuav tsum tau ua ntej rau kev txhawb nqa. Hauv kev tsim cov pob tawb dai thiab kev hla kev hla tus dej, nws tseem tuaj yeem muab txoj hauv kev yooj yim rau kev tsim kho, ua kom nrawm dua thiab yooj yim ntawm kev tsim kho. Bailey choj sib dhos nrog chord reinforcements: Tus choj nrog chord reinforcements hais txog kev ntxiv chord reinforcements ntawm sab saud thiab qis chords ntawm truss. Cov qauv thiab kev sib txuas ntu ntawm tus choj yog ib yam zoo ib yam ntawm cov choj uas tsis muaj kev txhawb nqa ntxiv, tshwj tsis yog cov kab sab saud thiab qis dua ntawm txhua lub pob zeb nyob nruab nrab ntawm tus choj tau ntxiv nrog chord txhawb ntxiv. Kev sib txuas ntawm chord reinforcement thiab truss yuav tsum ua los ntawm chord bolts, thiab chord reinforcement yuav tsum txuas nrog los ntawm truss pins. Txhawm rau tiv thaiv tus choj los ntawm kev cuam tshuam hauv tus txheej txheem ntawm kev tawm tsam, lub chord inclined tau teeb tsa ntawm qis chord truss yam tsis muaj kev txhawb nqa chord ntawm ob qho kawg ntawm tus choj. Hauv ob lossis peb kab txuas ntxiv txuas txuas txuas, sab saum toj kev txhawb nqa ntawm thawj kab thiab kab thib ob trusses tau teeb tsa ntawm cov chords txhawb nqa. Cov hlua khi txuas txuas tus ncej thiab chord txhawb nqa yuav tsum tau teeb tsa ntawm chord qhov cuab yeej ua ntej ua ntej chord qhov txuas tau txuas nrog lub truss, txwv tsis pub lub bolts tsis tuaj yeem tso thaum thav duab tau teeb tsa.
