Variable-curvature wedge block type self-anchoring anchorage device of double-layer CFRP plate cable and implementation method of variable-curvature wedge block type self-anchoring anchorage device
In the field of CFRP inhaul cable roof structures, the invention provides a self-anchoring anchorage device of a double-layer CFRP plate inhaul cable and an implementation method of the self-anchoring anchorage device, the self-anchoring anchorage device structurally comprises an anchor cup, a variable-curvature wedge block, bin dividing plates and a CFRP one-way plate, the anchor cup is of a cylindrical structure, a rectangular through hole is formed in the end of the anchor cup, the rectangular through hole axially penetrates through the anchor cup, the number of the bin dividing plates is matched with the number of wedge-shaped channels, and the variable-curvature wedge block and the CFRP one-way plate are arranged on the CFRP one-way plate. A partition plate is installed in each wedge-shaped channel, a CFRP one-way plate is arranged between every two adjacent partition plates, the two variable-curvature wedge blocks are installed in the rectangular through holes, the attaching faces of the variable-curvature wedge blocks and the inner wall of the anchor cup are variable-curvature curved faces, the faces, opposite to the variable-curvature curved faces, in the variable-curvature wedge blocks are planes, and the surfaces, opposite to the variable-curvature curved faces, in the variable-curvature wedge blocks are flat surfaces. When the side section of the variable-curvature curved surface of the simplified variable-curvature wedge block is a line, the line is a variable-curvature line; according to the self-anchoring anchorage device, on the premise that the anchoring length is not increased, the double-layer CFRP plate cable can be subjected to self-anchoring anchoring, and the problem that an existing wedge-shaped anchorage device can only be applied to a single-layer CFRP plate cable is solved.
在CFRP拉索屋盖结构领域中，本发明提供一种双层CFRP板拉索的自锚锚具及其实施方法，其结构包括：锚杯、变曲率楔块、分仓板和CFRP单向板，锚杯为圆柱状结构，锚杯的端部设置矩形通孔，矩形通孔轴向贯穿锚杯，分仓板的数量与楔形通道的数量适配，每个楔形通道内安装一个分仓板，相邻的两个分仓板之间设置一个CFRP单向板，两个变曲率楔块安装在矩形通孔中，变曲率楔块与锚杯的内壁的贴合面为变曲率曲面设置，在变曲率楔块内与变曲率曲面对立的面为平面设置，当简化变曲率楔块的变曲率曲面的侧截面为线条时，线条为变曲率线条；本自锚锚具能在不增加锚固长度的前提下，对双层CFRP板索进行自锚锚固，以解决现有的楔形锚具只能应用于单层CFRP板索的问题。
