Retard-bonded prestressed tendon supporting and positioning device
The invention provides a retard-bonded prestressed tendon supporting and positioning device which comprises a plurality of supporting frames and a plurality of rolling wheels, and the multiple supporting frames are symmetrically distributed on the two sides of the same section of a retard-bonded prestressed beam reinforcement cage in the width direction of the retard-bonded prestressed beam reinforcement cage; a plurality of rollers are rotationally arranged on each support frame, and the plurality of rollers on the same support frame are distributed in the length direction of the retard-bonded prestressed beam reinforcement cage; a positioning groove used for positioning the retard-bonded prestressed tendon is formed in the supporting frame or the surface of the idler wheel. When the supporting frame is stressed, elastic deformation can be generated so that the rollers can be attached to the surface of the retard-bonded prestressed tendon, supporting force on the retard-bonded prestressed tendon can be dispersed on the rollers, and the situation that an outer sleeve of the retard-bonded prestressed tendon is broken due to the fact that the supporting force is excessively concentrated is avoided.
本发明提供了一种缓粘结预应力筋支撑定位装置，其包括多个支撑架和多个滚轮，多个所述支撑架沿着缓粘结预应力梁钢筋骨架的宽度方向对称分布于所述缓粘结预应力梁钢筋骨架同一截面的两侧；所述支撑架上均转动设置有多个所述滚轮，并且同一个所述支撑架上的多个所述滚轮沿着所述缓粘结预应力梁钢筋骨架的长度方向分布；所述支撑架上或所述滚轮表面开设有用以定位缓粘结预应力筋的定位槽。所述支撑架受到压力时会产生弹性形变以使多个所述滚轮均能够与缓粘结预应力筋表面贴合，使得对缓粘结预应力筋的支撑力分散在多个所述滚轮上，以避免因支撑力过于集中而导致缓粘结预应力筋的外套管破裂。
