Cov yeeb nkab truss yog hais txog cov qauv lattice uas muaj cov pas nrig puag ncig txuas rau ib leeg ntawm qhov kawg.Lub truss ua rau cov khoom siv ntawm cov qauv kev lag luam, cov qauv yog lub teeb hauv qhov hnyav, thiab nws yooj yim los tsim ntau yam duab kom haum rau kev siv sib txawv, xws li kev txhawb nqa trusses, arches, thav duab thiab yees.Lub truss yog hais txog cov qauv lattice uas muaj cov pas nrig txuas rau ib leeg ntawm qhov kawg, thiab cov yeeb nkab truss txhais tau hais tias cov pas nrig hauv cov qauv yog tag nrho cov yeeb nkab txuas.Feem ntau, cov rods nyob rau hauv lub truss tsuas yog raug rau axial nro los yog siab, thiab cov kev nyuaj siab yog sib npaug zos rau ntawm tus ntoo khaub lig-section, yog li nws yog ib qho yooj yim mus ua si lub luag hauj lwm ntawm cov ntaub ntawv.Cov yam ntxwv no ua rau cov qauv truss yig hauv cov ntaub ntawv thiab cov qauv me me.Nws yog ib qho yooj yim los tsim ntau yam duab kom hloov mus rau kev siv sib txawv, xws li kev txhawb nqa trusses, arches, thav duab thiab yees, thiab lwm yam. Yog li ntawd, truss lug siv nyob rau hauv ntau lub tsev loj-span venues niaj hnub no, xws li cov rooj sib tham thiab exhibition chaw, stadiums. los yog lwm yam loj-scale Nws yog dav siv nyob rau hauv pej xeem vaj tse.

Feem ntau ntawm cov rods nyob rau hauv lub truss qauv yog txuas nrog welding ntawm cov nodes.Ua ntej welding, lub web thiab chord yuav tsum tau txiav raws li cov duab ntawm vuam seam ntawm txhua tus pas nrig yuav tsum tau welded.Xaus yog txiav nrog cov kab sib tshuam thiab chords yog grooved.Txij li cov rods nyob rau hauv lub truss qauv sib tshuam nrog ib leeg nyob rau hauv daim ntawv ntawm kev sib tshuam kab, cross-sectional zoo ntawm tus pas nrig kawg yog complex, yog li nyob rau hauv lub tiag tiag txiav txheej txheem, ob txoj kev ntawm mechanical tsis siv neeg txiav ua thiab phau ntawv phau ntawv txiav ua. feem ntau yog siv.ua.
