External prestressing cable restraining device for wind power tower cylinder

The utility model discloses a wind power tower cylinder external prestress cable body restraining device which is composed of two parts, namely a strip-shaped band edge steel plate pasted with a flexible protection material and a semi-annular band edge steel plate pasted with a flexible protection material, a semi-annular cylinder is defined by the strip-shaped band edge steel plate and the semi-annular band edge steel plate, the inner wall of the semi-annular cylinder is made of the flexible protection material, and a prestress cable can penetrate through the flexible protection material. According to the restraining device, friction between the cable body and the peripheral hole wall is reduced, meanwhile, the structural safety advantage of wall-attached operation of the cable in the body is achieved, and the bow stretching effect caused by too large deformation difference between the prestressed cable and the tower body under the extreme condition is reduced. 本实用新型公开了一种风电塔筒体外预应力索索体约束装置，由两部分组成：粘贴有柔性防护材料的条形带
