Variable-curvature wedge-shaped clamping piece type anchorage device for multi-layer carbon fiber plate
The invention discloses a multi-layer carbon fiber plate variable-curvature wedge-shaped clamping piece type anchorage device used in the field of building reinforcement. The multi-layer carbon fiber plate variable-curvature wedge-shaped clamping piece type anchorage device comprises an anchor head and a clamping piece. The clamping piece comprises a variable-curvature wedge-shaped upper clamping piece and a variable-curvature wedge-shaped lower clamping piece; the variable-curvature wedge-shaped upper clamping piece and the variable-curvature wedge-shaped lower clamping piece are the same in size and opposite in curvature; the whole anchor head is in a cuboid shape, a conical hole is formed in the longitudinal direction, the hole end is in a rectangular shape, a hole in the loading end is small, and a hole in the free end is large. Arc-shaped chamfers are arranged at the outer ends of the variable-curvature wedge-shaped clamping pieces and inside the anchor head, the curvature faces of the inner surfaces of the two variable-curvature wedge-shaped clamping pieces are bonded with the multiple layers of carbon fiber plates through colloid, and the clamping pieces are inserted from the large hole end of the anchor head after being bonded with the multiple layers of carbon fiber plates. The problem that the multi-layer carbon fiber plate is abnormally damaged at the loading end of the anchorage device due to stress concentration can be solved, field assembly is convenient and fast, efficiency is high, and construction universality is good.
本发明公开了一种用于建筑加固领域的多层碳纤维板变曲率楔形夹片式锚具装置，包括有锚头和夹片；夹片包括变曲率楔形上夹片和变曲率楔形下夹片；所述变曲率楔形上夹片和变曲率楔形下夹片的尺寸相同，曲率相反；所述锚头的整体呈长方体型，纵向有锥形孔，孔端呈长方形，加载端孔洞较小，自由端孔洞较大；所述变曲率楔形夹片的外端以及锚头内部设有圆弧形倒角、两个变曲率楔形夹片内表面曲率面与多层碳纤维板通过胶体粘结，夹片与多层碳纤维板粘结后由锚头的大孔端插入。本发明可以解决多层碳纤维板在锚具加载端由于应力集中而产生非正常破坏的问题，现场组装便捷，效率高，施工普适性好。
