Pile foundation reinforcement cage top centering and positioning tool
The invention relates to the technical field of cast-in-place pile reinforcement cage positioning, in particular to a pile foundation reinforcement cage top centering positioning tool which comprisesa ring sleeve matched with the inner wall of a pile casing, at least three vertical first steel columns are evenly welded and fixed to the top of the ring sleeve at intervals, and at least three vertical second steel columns are evenly welded and fixed to the top of the pile casing at intervals. The first steel columns and the second steel columns are the same in number. The number of the arc-shaped plates is the same as that of the first steel columns, and all the arc-shaped plates are centrosymmetric about the central axis of the pile casing. The movable ends of all the arc-shaped plates rotate in the same direction by rotating the ring sleeve, so that the purpose of enlarging or shrinking the clamping hole is achieved, the top of the reinforcement cage extends into the clamping hole, the clamping hole is gradually shrunk to enable the center of the reinforcement cage to move towards the central axis of the pile casing, and centering of the top of the reinforcement cage is achieved.Annular reinforcing ribs are welded to acoustic pipes arranged on the reinforcement cage to extend the top of the reinforcement cage, so that the short reinforcement cage can also extend into the clamping holes.
本发明涉及灌注桩钢筋笼定位技术领域，尤其是涉及一种桩基钢筋笼顶部对中定位工装，包括与护筒内壁配合的环套，环套顶部间隔均匀地焊接固定至少三根竖直的第一钢柱，护筒顶部间隔均匀地焊接固定至少三根竖直的第二钢柱，第一钢柱与第二钢柱的数量相同；还包括数量与第一钢柱相同的弧形板，所有弧形板关于护筒的中轴线成中心对称。本发明通过旋转环套使所有弧形板的活动端同向旋转，从而达到扩大夹孔或缩小夹孔的目的，将钢筋笼顶部伸于夹孔内，逐渐缩小夹孔使钢筋笼的中心向护筒的中轴线处移动，实现了钢筋笼顶部的对中；利用钢筋笼上自带的声测管焊接环形加强筋作为钢筋笼顶部的延长，使较短的钢筋笼也能伸于夹孔中。
