文章分析了预应力锚具板的强度和变形,通过有限元分析发现,通常工程中所用的锚板都是在上边1/5高度的地方位移和应力最大,最先屈服,这样一来下部比较厚的锥型壁材料得不到有效利用,显然受力不合理.为此,笔者与中南预应力有限公司联合研究,改变了夹片的度,即从6.5°变为6.25°,? This paper analyzes the strength and deformation of prestressed anchorage plates. Through finite element analysis, it is found that usually the anchor plates used in the project are located in the upper 1/5 height where the displacement and stress are the largest and yield first, so that the lower part is compared The use of thick tapered wall materials cannot be effectively used. It is obviously unreasonable to exert force. For this reason, the author and Zhongnan Prestress Co., Ltd. jointly studied and changed the degree of the clip, that is, from 6.5° to 6.25°.
