Overall rapid installation method for large-span box girder reinforcement cage
The invention provides an overall rapid installation method for a large-span box girder steel reinforcement framework, which comprises the following steps: calculating deformation of the steel reinforcement framework and deformation of a portal girder, and determining the position of the lowest point; a locking tool is installed at the lowest point position of the manufactured steel reinforcement framework; a concave locking notch tool is installed at the corresponding position of the flange formwork main beam; calibrating the position of a multi-stage signal transmitter on a gantry main beam; a receiver on the steel reinforcement framework locking tool is adjusted; hoisting and longitudinally moving the reinforcement cage; when the receiver receives the signal transmitted by the first signal transmitter, the longitudinal movement speed of the reinforcement cage is reduced; the reinforcement cage moves longitudinally at a low speed, and when the receiver receives the signal transmitted by the second signal transmitter, the reinforcement cage stops moving longitudinally; and the steel reinforcement framework is lowered into the formwork, and the concave locking notch tool in the flange formwork girder is matched with the locking tool. Rapid installation of the whole-span box girder steel reinforcement framework is achieved through the technologies such as tool locking and laser positioning, and the problem that the steel reinforcement framework is difficult to enter a mold accurately is effectively solved.
本发明提供一种大跨箱梁钢筋骨架整体快速安装方法，计算钢筋骨架变形及门架主梁变形，确定最低点位置；在制作完成后的钢筋骨架的最低点位置处安装锁定工装；在翼缘模架主梁相应位置安装凹型锁定槽口工装；标定门架主梁上的多级信号发射器的位置；调整钢筋骨架锁定工装上的接收器；钢筋骨架起吊及纵移；当接收器接受到第一信号发射器发射的信号时，钢筋骨架纵移速度下降；钢筋骨架低速纵移，当接收器接受到第二信号发射器发射的信号时，钢筋骨架停止纵移；钢筋骨架下放至模架内，翼缘模架主梁内部的凹型锁定槽口工装与锁定工装配合。通过锁定工装及激光定位等技术实现整跨箱梁钢筋骨架快速安装，有效解决钢筋骨架难以准确入模的问题。
