Pressure-bearing and anchoring integrated prestressed anchorage device
The invention discloses a pressure-backing and anchoring integrated prestressed anchorage device, relates to the technical field of engineering construction tools, and aims at solving the problem thatstress borne between an existing anchor plate and a steel strand is large. The upper end of an anchor backing plate is provided with an anchor plate, the anchor backing plate and the anchor plate areintegrally formed, a plurality of clamping pieces are arranged in the anchor plate in an annular array mode, the clamping pieces are of a conical structure, backing blocks are arranged at the lower ends of the clamping pieces, a fixed cylinder is arranged in the middle of the lower end of the anchor backing plate, the fixed cylinder is fixedly connected with the anchor backing plate, steel strands are arranged in the clamping pieces, penetrate through the anchor backing plate and the anchor plate and extend to the lower portion of the fixed cylinder, a plurality of grouting holes evenly distributed in the circumferential direction are formed in the outer portion of the anchor backing plate, and spiral ribs are arranged on the outer portion of the lower end of the anchor backing plate andspirally distributed on the outer portion of the fixed cylinder.
本发明公开了承压锚固一体预应力锚具，涉及工程建筑用具技术领域，为解决现有的锚板与钢绞线之间所受应力较大的问题。所述锚垫板的上端设置有锚板，且锚垫板与锚板一体成型，所述锚板的内部呈环形阵列开设有若干个夹片，且夹片呈锥形结构，所述夹片的下端均设置有轴承块，所述锚垫板下端的中间位置处设置有固定筒，且固定筒与锚垫板固定连接，所述夹片的内部设置有钢绞线，且钢绞线穿过锚垫板、锚板并延伸至固定筒的下方，所述锚垫板的外部设有多个沿圆周均匀分布的注浆孔，所述锚垫板下端的外部设置有螺旋筋，且螺旋筋呈螺旋分布于固定筒的外部。
