Ultra-high-performance concrete centrifugal pole
The invention discloses an ultra-high-performance concrete centrifugal pole. The ultra-high-performance concrete centrifugal pole comprises ultra-high-performance concrete and a framework, the framework is embedded into the ultra-high-performance concrete and comprises a plurality of main bars, auxiliary bars, mesh spiral bars, inner steel hoops and nut protection layers, the main bars and the auxiliary bars are parallel to each other and penetrate through the ultra-high-performance concrete at intervals, the outer side edge of the main bars and the outer side edge of the auxiliary bars are located on the same circumference, the mesh spiral bars are wound around the outer side of the main bars and the outer side of the auxiliary bars and comprises transverse bars and longitudinal bars, thetransverse bars and the longitudinal bars are fixedly connected with the contact positions of the main bars and the auxiliary bars, the inner steel hoops are distributed at equal intervals in the length direction of the centrifugal electric pole and fixed to the inner sides of the auxiliary bars, and the nut protection layers are fixed to the outer sides of the auxiliary bars. According to the ultra-high-performance concrete centrifugal pole, the problems of winding looseness and large spacing deviation of traditional spiral bars are avoided, meanwhile, the contact area of the spiral bars andultra-high performance concrete is increased, the strength of the centrifugal electric pole is remarkably improved, and the risk of cracks of the centrifugal electric pole is reduced.
本发明公开了一种超高性能混凝土离心电杆，包括超高性能混凝土和骨架，骨架嵌入超高性能混凝土中，骨架包括若干主筋、附筋、网片螺旋筋、内钢箍和螺母保护层，主筋和附筋相互平行且相间穿设在超高性能混凝土中，主筋的外侧边和附筋的外侧边均位于同一圆周上，网片螺旋筋缠绕在主筋和附筋的外侧，网片螺旋筋包括横向筋和纵向筋，横向筋和纵向筋与主筋和附筋的接触处均固定连接，内钢箍沿离心电杆的长度方向等间距分布并固定在附筋的内侧，螺母保护层均固定在附筋的外侧。本发明规避了传统螺旋筋缠绕松动以及间距偏差大的问题，同时增大了螺旋筋与超高性能混凝土的接触面积，以显著提高离心电杆的强度，减小离心电杆裂纹发生的风险。
