Isakhiwo Se-Space Truss: Inketho Ekhethwayo Yezakhiwo Zomphakathi Ezibanzi

Njengegatsha elibalulekile lesakhiwo segridi yendawo, isakhiwo se-truss yesikhala sibonisa ukusebenza okuphezulu kwemishini, isisindo esilula, ukuqina okuphezulu, ukumelana nokuzamazama komhlaba okuhle kakhulu, izindleko eziphansi nokubunjwa okulula. Sekuyiyona ndlela ekhethwayo yokwakha uphahla lwezakhiwo ezinkulu zomphakathi njengezikhumulo zezindiza, izinkundla zemidlalo, izikhungo zemibukiso kanye neziteshi.

Isakhiwo se-Space truss siwuhlobo olukhulu lwesistimu yegridi yendawo. Kuyisakhiwo se-spatial bar esakhiwe ngamalungu ahlelwe njalo futhi axhunywe ngamajoyinti. Iklanywe ngokuyinhloko njengamagridi anezingqimba ezimbili noma ezendlalelo eziningi, ahluke kumagobolondo anesendlalelo esisodwa.

Izakhiwo ze-Space truss zivame ukwamukelwa ezakhiweni zophahla, ikakhulukazi ezisezingeni elilodwa kanye nezimo eziyisicaba. Zisetshenziswa kabanzi ezakhiweni zomphakathi kuhlanganiseizindawo zokuzivocavoca, amahholo ombukiso, amahholo okulinda eziteshinifuthiizikhumulo zezindiza. Eminyakeni yamuva, ziye zasetshenziswa futhi izakhiwo zezimboni ezifanaizindawo zokugcina izimpahla, ama-hangars nama-workshop asefekthri. Ngokuziqhenya ngezinzuzo ezihlukene, zigqama njengenketho evamile yezakhiwo zomphakathi ezinkulu.

Isikhala esikhulu esingenakholomu.

Izakhiwo ze-Space truss zithola kalula ukumbozwa ngaphandle kwamakholomu ukusuka kumamitha angama-60 kuye kwayi-150, kwakheka indawo yangaphakathi evuleke ngokugcwele futhi ebanzi. I-Beijing Capital Gymnasium yamukela isakhiwo se-space truss ene-span yamamitha angu-99 namamitha angu-112.2. Le nzuzo yenza i-space truss ibe yisinqumo esijwayelekile ophahleni lwetheminali yesikhumulo sezindiza.

Ukusebenza kahle kwezomnotho okumangalisayo.

Isakhiwo sibonisa ukusetshenziswa kwensimbi okuphansi kanye nezindleko ezilawulekayo eziphelele. Ishede lensimbi le-Hangzhou Renhe Grain Reserve Terminal lisebenza nge-truss yesikhala sephiramidi enezikwele ezinezikwele ezimbili, enebanga eliphakeme lamamitha angama-95, iletha ukwakhiwa okubiza izindleko.

Ukusebenza okuhle kakhulu kwe-seismic.

Ngenxa yokuphindaphindeka kwengcindezi yendawo ephezulu, i-ductility enhle kanye nesisindo somzimba esilula, izakhiwo ze-truss yesikhala zidlula izakhiwo zekhonkolo zendabuko ekumelaneni nokuzamazama komhlaba. Njengesakhiwo sehabhu elikhulu kakhulu endaweni yokuzamazama komhlaba, i-Beijing Daxing International Airport Terminal ifakwe ama-arolation bearings angu-1152 kanye nama-dampers angu-160 ukuqinisekisa ukuvikelwa okusebenzayo ekuzamazameni komhlaba okunamandla.

Isitayela sezakhiwo esiguquguqukayo.

Isakhiwo singakwazi ukubona izimo eziyinkimbinkimbi ezifana ne-hyperboloid, indawo yefomu yamahhala kanye nendawo yamagagasi eqhubekayo, ehlangabezana nezidingo zedizayini eyingqophamlando yezakhiwo zomphakathi zesimanje. Uphahla oluyinhloko lweSikhumulo Sezindiza i-Zhuhai T2 Terminal luthatha ubude besikhathi obuguquguqukayo-curvature hyperboloid hollowed steel truss. Isikhungo Sezemidlalo sase-Shenzhen Bay sihlanganisa igobolondo elenziwe ngongqimba olulodwa kanye ne-truss egobile enezendlalelo ezimbili, zombili zisebenza njengezibonelo zesakhiwo esiyingqayizivele.

Ngaphezu kwalokho, izakhiwo ze-truss yesikhala ziza ngezindlela ezihlukahlukene ngezigaba eziyinhloko kanje:

I-truss yesikhala enezendlalelo ezimbili, esakhiwe amachords aphezulu, izingoma ezingezansi namalungu ewebhu, iyindlela evame ukutholwa.

Ukukhethwa kwesakhiwo se-truss yesikhala kunqunywa ngokuphelele izici ezihlanganisa isakhiwo sepulani, izidingo zezakhiwo, umthwalo, ubude besikhathi, isimo sokusekela kanye nezindleko zokwakha.

Sekukonke, ukwamukela izakhiwo ze-truss yesikhala kuvumela ukudala izikhala ezinkulu ngezinto ezimbalwa. Ngokumelene nesizinda sokuthuthukiswa kwekhwalithi ephezulu kanye nokwakhiwa okuluhlaza, i-space truss isebenza njengohlaka oluqinile oluwumgogodla wezakhiwo zomphakathi ezinkulu.
