Isingeniso somkhiqizo
Ifomu lesakhiwo se-chord eqinisiwe lifana nezintambo ezingaphezulu neziphansi zeyunithi ye-truss. Usayizi wokuxhuma ongu-321 ungu-3000mm ubude, kanti usayizi wokuxhuma ongu-200 ungu-3048mm. Ngokuyinhloko isetshenziselwa ukuqinisa ama-chords aphezulu naphansi ama-trusses amabhuloho ajwayelekile noma amabhuloho akhethekile. I-chord eqinisiwe ihlinzekwa ngemigqa emibili yezisekelo zokuxhuma ezingaphezulu neziphansi, umugqa ophansi ulungele ukuxhuma ne-truss chord, umugqa ongenhla ulungele ukuxhuma nohlaka lokusekela, kanye neyunithi ye-truss ephezulu yokuphela kwebhuloho labesifazane futhi isiphetho sebhuloho lesilisa ngokuvamile asifakelwe izingoma eziqinisiwe. Ngokuvamile i-reinforcing chord isethwe ngokuphambene ngokuqondile nento ye-truss. Uhlobo lwama-200 lungaphinda lunyakazise amalunga endlebe eyodwa nakabili wechodi eqinisiwe kanye namalunga endlebe eyodwa nakabili weyunithi ye-truss.
Ukucaciswa Komkhiqizo
Uhlobo lwe-321 i-reinforced chord inesisindo esingama-80 kg; uhlobo lwama-200 lwe-reinforced chord lunesisindo esingama-90 kg.
ukusetshenziswa komkhiqizo
1 Ukwandisa amandla ebhuloho le-bailey
2 Ingxenye ye-Bailey Bridge
3 Ixhunywe kuphaneli ngamabhawudi
