Reinforcement cage deviation prevention device for pile foundation pouring under complex conditions
The invention provides a reinforcement cage deviation prevention device for pile foundation pouring under complex conditions, and belongs to the technical field of cast-in-place pile construction. According to the technical scheme, the device comprises a vertical connecting rod piece, one side of the outer side face of the vertical connecting rod piece is provided with an upper-end hanging bar movable ring and a lower-end hanging bar movable ring which are coaxial, and the other side of the outer side face of the vertical connecting rod piece is provided with an upper-end lateral limiting part and a lower-end lateral limiting part which are used in cooperation with the inner side wall face of a pile casing; the side, away from the vertical connecting rod piece, of the upper end lateral limiting part is provided with a pile casing end clamping structure. The device has the beneficial effects that the technical problem that the steel reinforcement cage deviates during concrete pouring can be solved, and steel reinforcement cage hanging bars are limited in a closed space formed by the vertical limiting buckles, the vertical connecting rod pieces and the hanging bar movable rings in the construction process; and displacement of the steel grate and deviation of the hanging bar caused by vibration of a vibrator and repeated removal of the guide pipe in the concrete pouring process are avoided.
本发明提供了一种复杂条件下桩基浇筑用钢筋笼防偏位装置，属于灌注桩施工技术领域。其技术方案为：包括竖向连接杆件，竖向连接杆件外侧面一侧分别设置有同轴心的上端吊筋活动环和下端吊筋活动环，竖向连接杆件外侧面另一侧分别设置有与护筒内侧壁面配合使用的上端侧向限位和下端侧向限位，上端侧向限位远离竖向连接杆件的一侧设置有护筒端卡位结构。本发明的有益效果为：可以解决混凝土浇注时钢筋笼偏位的技术问题，施工过程中钢筋笼吊筋被限制在由竖向限位卡扣、竖向连接杆件和吊筋活动环构成的封闭空间内，不会因混凝土浇筑过程中振动器振捣和多次拔除导管会导致钢篦子产生位移、吊筋偏位。
