Prefabricated Highway Steel Choj muaj plaub ntu

Prefabricated txoj kev loj steel choj muaj truss girder, lawj system, kev sib txuas system thiab lub hauv paus, thiab yog nruab nrog tshwj xeeb erection cov cuab yeej. Lub nqaj loj yog ua los ntawm txhua 3-meter-ntev truss txuas nrog tus pin, nyob rau ntawm ob sab ntawm txoj kev, txuas nrog ib kab nruab nrab ntawm lub ntsiab nqaj, txhua lub truss yog muab nrog ob kab; Plaub pawg ntawm longons yog teem rau ntawm kab, nruab nrab ob pawg yog non-buckled lengthons, thiab sab nrauv ob pawg yog buckled lengthons; Lub longon yog paved nrog ntoo choj board, thiab ob sab ntawm lub choj board yog tsau nrog cov ntaub ntawv ntug, thiab ob qho tib si kawg ntawm tus choj yog muab nrog kawg kab. U-hom choj board tuaj yeem tso ncaj qha rau ntawm kab. Lub ntsiab nqaj yog kev txhawb nqa ntawm lub rooj zaum choj (kev txhawb nqa) thiab lub rooj zaum phaj ntawm kab kawg, tus choj thiab txoj kev tawm yog txuas nrog tus choj taub hau phaj, nruab nrab yog tsis muaj buckle phaj, ob sab yog buckle phaj, phaj yog nteg rau ntawm tus choj phaj, tsau ntug khoom. Tag nrho cov choj yog nruab nrog ntau yam sib txuas xws li kab pheeb ces kaum, cua - resistant khi rods, kev txhawb nqa thav duab, txuas daim hlau, thiab lwm yam, kom tus choj tsim ib tug ruaj khov spatial qauv.

Txhawm rau hloov mus rau qhov kev hloov pauv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv, 10 cov kev hloov pauv raug pom zoo rau kev sib xyaw ua ke, uas yog ib kab ib txheej (Lus Askiv sau luv SS), ob kab ib txheej (DS), peb kab ib txheej (TS), ob npaug. kab ob txheej (DD), peb kab ob txheej (TD) thiab tsib daim ntawv ntawm kev ntxiv cov hlua khi rau ntawm cov hlua sab sauv thiab qis ntawm cov saum toj no tsib kev sib txuas. Thaum ntxiv cov hlua ntxiv, lo lus "txhim kho" (ntxiv "R" hauv lus Askiv) feem ntau yog muab, piv txwv li, "peb-kab ib-txheej reinforcing (TSR)", thiab lwm yam. Choj load, ncua thiab truss ua ke.
