Reinforcing device for fabricated concrete square column
The invention discloses a reinforcing device for a fabricated concrete square column, which is characterized in that stretching bases are fixedly arranged at the top end and the bottom end of the side surface of the concrete square column, more than two fixed bases are arranged between the two stretching bases, and first reinforcing steel bar holes through which prestressed reinforcing steel bars can penetrate are longitudinally formed in the stretching bases and the fixed bases; the two ends of the prestressed steel bar are both in threaded connection with prestressed nuts, second steel bar holes allowing the threaded steel bar to penetrate through are further transversely formed in the stretching base and the fixed base, the two ends of the threaded steel bar are both in threaded connection with fastening nuts, the square pipe is arranged on the outer side of the concrete square column in a sleeving mode, and L-shaped steel plates are arranged at the four corners of the inner side of the square pipe. And the L-shaped steel plate and the square tube are fixedly connected with the twisted steel. The splicing type structure is adopted, large machines do not need to be arranged on site, construction is convenient, the construction period can be shortened, and meanwhile the horizontal rigidity, the flexural capacity and the crack resistance of the concrete column can be comprehensively improved through the prestressed steel bars fixed to the periphery of the concrete square column.
本发明公开了一种装配式混凝土方柱的加固装置，混凝土方柱的侧面顶端和底端均固设有拉伸基座，两个拉伸基座之间设置有两个以上的固定基座，拉伸基座和固定基座均纵向开设有供可供预应力钢筋穿过的第一钢筋孔，预应力钢筋两端均螺纹连接有预应力螺母，拉伸基座和固定基座上还横向开设有可供螺纹钢筋穿过的第二钢筋孔，螺纹钢筋两端均螺纹连接有紧固螺母，方管套设于混凝土方柱外侧，方管内侧的四个拐角处均设置有L型钢板，且L型钢板和方管均与螺纹钢筋固定连接。本发明采用拼接式结构，现场无需配备大型机械，施工方便，能够缩短施工周期，同时固定在混凝土方柱四周的预应力钢筋，能够全面提高混凝土柱的水平刚度、抗弯承载力和抗裂性能。
