Multi-layer FRP plate anchoring device and anchoring method
The invention discloses a multi-layer FRP plate anchoring device and anchoring method, and the anchoring method comprises the steps: an anchor plate which is provided with an anchoring channel with an isosceles trapezoid-shaped cross section; the base plate is a metal plate filled between the two layers of FRP plates in the anchoring area; the clamping piece is filled between the surfaces of the upper-layer FRP plate and the lower-layer FRP plate and the anchoring channel; the clamping piece is a wedge-shaped block with a small front end and a large rear end; the top plate is a square metal plate with a square hole; the base plate and the clamping piece are connected to transmit shearing force; the bolt pin is used for fixing the multiple layers of base plates and transmitting force from the base plates to the top plate; the bolt pin is a semi-cylinder. According to the anchoring method for the multiple layers of FRP plates, the multiple layers of composite thin plates can be effectively anchored, and compared with an FRP thick plate under the same sectional area, the anchoring length is shortened. And the FRP plate is subjected to ideal bursting type damage, so that the tensile strength of the material can be fully exerted.
本发明公开了一种多层FRP板锚固装置及锚固方法，其中锚固方法包括：锚板，具有一截面形状为等腰梯形的锚固通道；垫板，填充在锚固区域的两层FRP板之间的金属板；夹片，填充在上、下层FRP板表面与锚固通道之间；所述夹片为前端小后端大的楔形块；顶板，具有方形孔洞的方形金属板；连接垫板与夹片以传递剪力；销栓，将多层垫板固定的装置，并将力从垫板传递至顶板；所述销栓为半圆柱体。本发明公开的一种多层FRP板锚固方法可以有效锚固多层复合材料薄板，相比同等截面积下FRP厚板的锚固长度有所缩短。FRP板发生理想的炸裂式破坏，可充分发挥材料拉伸强度。
