以高强钢丝代换预应力砼托架下弦冷拉Ⅳ钢筋的设计与施工

Design and construction of the using hight strength cable to replace cold drawn bar Ⅳ in bracket member of prestressed concret

近年来，我国预应力高强钢丝发展较快，大量节约钢材，改善预应力施工工艺提高预应力施工质量。由此预应力高强钢丝代替冷拉预应力钢筋是我国钢筋发展的趋向。

Recently, hight strength cable development fast in prestressed concret, which has lowered consumption,improved the craft of pestressed force and promoted the quality of construction. therefore It is development trends in our country that using hight strength cable to replace cold drawn bar.
