| Abstract: | To improve performance of truss prestress truss is crossing ability, reduce the deflection of an effective measures of trusses,such as prestressed inclined stay truss supports system, prestressed cable supported truss supports system was introduced. Combined with practical work ,the construction process and construction inclined stay truss supports system, the construction process and quantity control measures used for prestressed cable supported truss supports system was introduced. Finally, the drawback of existing truss formwork supports system and next develop orientation was proposed. |
