Pre-tensioning method precast beam tensioning concrete reaction wall
The invention discloses a pre-tensioning method precast beam tensioning concrete reaction wall which comprises a side jack, a reaction wall body, ear walls, a pull rod, an anchoring vehicle, a plurality of steel strands, a bogie, a vertical jack, a main bogie and a concrete bearing platform foundation, the rear end of the reaction wall body is connected with the two ear walls, one end of each steel strand is fixed to the anchoring vehicle, and the other end of each steel strand is fixed to the pull rod. The vertical jack is fixed to the concrete bearing platform foundation and drives the main bogie to move up and down so as to provide pulling force of the steel strand, and the reaction wall and the lug wall are fixed to the concrete bearing platform foundation. According to the device, through cooperation of the reaction wall, the lug wall, the pull rod, the anchoring vehicle, the steel strands, the bogie and the vertical jack, the vertical jack is driven to conduct tension transmission, the anchoring vehicle is tensioned to meet the tensioning requirement, the device is applied to tensioning construction of a pre-tensioning method precast beam, and the problems that the pre-tensioning force is large, and safety is insufficient are solved.
本发明公开了一种先张法预制梁张拉混凝土反力墙，包括侧部千斤顶、反力墙、耳墙、拉杆、锚固车、若干根钢绞线、转向架、竖向千斤顶、主转向架、混凝土承台基础，反力墙的后端衔接有两个耳墙，钢绞线的一端固定于锚固车，另一端绕经转向架上的滚轮并向主转向架上的滚轮延伸，竖向千斤顶固定于混凝土承台基础并带动主转向架上下移动进而提供钢绞线的拉力，反力墙、耳墙固定于混凝土承台基础。本装置通过反力墙、耳墙、拉杆、锚固车、若干根钢绞线、转向架、竖向千斤顶的配合，驱动竖向千斤顶进行拉力传递，对锚固车进行张拉而达到张拉要求，在先张法预制梁的张拉施工中应用，解决了预张拉力大、安全性不足的问题。
