hordhaca alaabta
Qaabka qaabdhismeedka xudunta la xoojiyay waxay la mid tahay koornada sare iyo hoose ee unugga truss.Cabbirka isku xirka 321 waa 3000mm oo dherer ah, cabbirka isku xirka 200 waa 3048mm.Waxaa inta badan loo isticmaalaa in lagu xoojiyo korka sare iyo hoose ee trusses buundooyinka caadiga ah ama buundooyinka gaarka ah.Qalabka la xoojiyay waxaa lagu bixiyaa laba saf oo ah taageerooyinka isku xirka sare iyo hoose, safka hoose wuxuu ku habboon yahay in lagu xidho xargaha xargaha, safka sare wuxuu ku habboon yahay in lagu xiro qaabka taageerada, iyo qaybta sare ee qaybta sare ee buundada dheddigga iyo dhammaadka buundada lab ah sida caadiga ah kuma qalabaysan xargaha la xoojiyay.Caadiyan xudunta xoojinta ayaa si toos ah uga soo horjeeda curiyaha truss-ka.Nooca 200 waxa kale oo uu gariirin karaa dhegta hal iyo laba laabta ah ee xudunta la xoojiyay iyo dhegta hal iyo labanlaab ah ee unugga truss.
