Reinforcing method and reinforcing structure for eccentric compression steel pipe concrete
The method comprises the following steps that at least one set of FRP sheets are bonded to a concrete-filled steel tube tension area, and the FRP sheets are arranged in the axis direction of the concrete-filled steel tube; a plurality of threaded pieces are constructed on the two sides of the FRP sheet, and the threaded pieces penetrate through the steel pipe of the concrete-filled steel pipe and are implanted into concrete inside the concrete-filled steel pipe; the anchoring part is installed and pressed on the outer surface of the FRP sheet, the threaded part penetrates through the anchoring part and is in threaded connection with the locking part, and the locking part is rotated so that the anchoring part can apply a set pressure load to the FRP sheet. The concrete-filled steel tube bearing capacity is improved.
本发明涉及一种偏心受压钢管混凝土加固方法及加固结构，包括以下步骤：在钢管混凝土受拉区粘结至少一组FRP片材，FRP片材沿钢管混凝土的轴线方向设置；在FRP片材的两侧施工多个螺纹件，螺纹件穿过钢管混凝土的钢管并植入钢管混凝土内部混凝土中；安装锚固件，锚固件压在FRP片材外表面，螺纹件穿过锚固件并螺纹连接锁紧件，转动锁紧件以使得锚固件对FRP片材施加设定压力荷载，采用本发明的加固方法对于偏心受压钢管混凝土加固效果好，同时能够抑制混凝土脱空现象的发生，提高钢管混凝土承载能力。
