Chiyambi cha malonda

Railway truss Bridge imatanthawuza mlatho wokhala ndi truss monga gawo lalikulu lonyamula katundu wa superstructure.Mlatho wa truss nthawi zambiri umapangidwa ndi chimango chachikulu cha mlatho, makina apamwamba ndi otsika opingasa komanso otalikirapo, chimango cha mlatho ndi cholumikizira chapakati, ndi njira yolumikizira mlatho.

Kugwiritsa ntchito mankhwala

Amagwiritsidwa ntchito ngati milatho ya njanji kapena ma viaducts a njanji ndi ma overpasses okhala ndi mipata yaying'ono.

Mlatho wa Railway Truss

Kapangidwe kazinthu

1. Truss Bridge ndi mtundu wa mlatho.
2. Milatho ya Truss imapezeka kawirikawiri m'njanji ndi m'misewu ya njanji;Imagawidwa m'mitundu iwiri yamphamvu yoyambira komanso mphamvu yapansi.
3. Thupi limapangidwa ndi chord chapamwamba, cholumikizira chapansi ndi ndodo yam'mimba;Mawonekedwe a ndodo ya m'mimba amagawidwa kukhala ndodo ya m'mimba, ndodo yowongoka ya m'mimba;Chifukwa cha kutalika kwake komanso kuwonda kwa ndodoyo, ngakhale kuti kugwirizana pakati pa ndodozo kungakhale "kokhazikika", nthawi yeniyeni yopindika ndodo nthawi zambiri imakhala yaying'ono kwambiri, kotero kuti mapangidwe ndi kusanthula akhoza kuphweka ngati "hinged".
4.Mu truss, chord ndi ziwalo zomwe zimapanga periphery ya truss, kuphatikizapo chojambula chapamwamba ndi chojambula chapansi.Mamembala omwe amalumikiza ma chords apamwamba ndi apansi amatchedwa mamembala a intaneti.Malingana ndi mayendedwe osiyanasiyana a mamembala a pa intaneti, amagawidwa kukhala ndodo za diagonal ndi ndodo zowongoka.
Ndege yomwe ma chords ndi maukonde amapezeka amatchedwa main girder plane.Kutalika kwa mlatho wa mlatho waukulu wa span kumasintha motsatira njira ya span kuti apange chingwe chopindika;zing'onozing'ono zapakatikati ndi zazing'ono zimagwiritsa ntchito kutalika kwa truss kosalekeza, zomwe zimatchedwa truss lathyathyathya kapena chingwe chowongoka.Mapangidwe a truss amatha kupangidwa kukhala mtengo kapena mlatho wa arch, ndipo angagwiritsidwenso ntchito ngati mtengo waukulu (kapena chitsulo chowumitsa) mu mlatho wothandizira chingwe.Milatho yambiri ya truss imapangidwa ndi chitsulo.Mlatho wa truss ndi wosanjikiza, kotero umatha kusinthika bwino pamasitima apawiri.

Ubwino wa mankhwala

1. mkulu kubala mphamvu
2.kumanga mwachangu liwiro
3.kupulumutsa mphamvu ndi kuteteza chilengedwe
4. maonekedwe okongola a nyumba
5.kuchita bwino kwa seismic
6. chitsimikizo cha khalidwe
