Isicelo somkhiqizo
Ngokuvamile isetshenziselwa amabhuloho omzila wezitimela anama-span amancane.
Ukwakheka Komkhiqizo
Ku-truss, i-chord amalungu akha i-periphery ye-truss, okuhlanganisa i-chord ephezulu kanye nechord ephansi.Amalungu axhuma amachords aphezulu naphansi abizwa ngokuthi amalungu ewebhu.Ngokwezikhombisi-ndlela ezihlukene zamalungu ewebhu, ahlukaniswe ama-diagonal rods kanye nezinduku eziqondile.
Indiza lapho ama-chords nama-webs etholakala khona ibizwa ngokuthi indiza ehlanganisa ama-main.Ukuphakama kwebhuloho lebhuloho elikhulukazi kuyashintsha ngokuhambisana ne-span ukuze kwakheke intambo egobile;ama-spans aphakathi nendawo amancane asebenzisa ukuphakama kwe-truss okuqhubekayo, okubizwa ngokuthi i-flat string truss noma intambo yentambo eqondile.Isakhiwo se-truss singakhiwa sibe ibhuloho noma ibhuloho le-arch, futhi singasetshenziswa njengesigxobo esiyinhloko (noma i-stiffening beam) ebhulohweni lesistimu yokusekela ikhebula.Iningi lamabhuloho ama-truss akhiwe ngensimbi.Ibhuloho le-truss liyisakhiwo esingenalutho, ngakho-ke likwazi ukuzivumelanisa nezimo ezinhle kudekhi ephindwe kabili.
Izinzuzo zomkhiqizo
Ibhuloho le-Steel truss lihlanganisa izinzuzo zensimbi nesakhiwo se-truss:
1. Isakhiwo esikhanyayo kanye nekhono elikhulu lokuhlanganisa
2. Kulula ukulungisa nokufaka esikhundleni
3. I-steel truss beam inamalungu amaningi nama-node, isakhiwo siyinkimbinkimbi, futhi ukuzinza kunamandla.
I-4.Ukumelana okuqinile nokucindezela nobuqotho obuhle
5. Uhlu olubanzi lokusetshenziswa
