摘要
利用钢筋缠绕获得一种新结构锚杆,通过改变锚杆的截面形状来提高锚杆横截面惯性矩,从而提高锚杆的抗剪能力,同时通过改变锚杆的外形结构来改变锚杆和水泥药卷的黏结性能。
A new structure anchor is obtained by twisting reinforcing steel. Remodeling of its cross sectional shape results increasing of the inertia moment, thereby shear strength of the anchor is increased, also bonding property to cement stick improved.
