摘要
对抗浮锚杆而言,与拉力型锚杆相比,压力型锚杆具有耐久性好、张拉锁定时对建筑物的防水结构影响小的特点,因而有其独特的优势和适用性。但是关于压力型锚杆的承载体,现行规范或图集中没有相对的统一标准,对压力型锚杆的的设计和施工造成一定的影响。文章依托工程实例,结合设计要求及相关规范对压力型抗浮锚杆的承载体进行优化设计。改进后的承载体以钢板作为承载体核心构件,以利于加工和现场使用为指导,变传统的T型锚设计为U型锚设计。在具体工程应用中达到良好的效果,为压力型锚杆承载体的推广应用提供了成功范例。
Pressure-type anti-floating anchors,compared with the tension-type anchors,have good durability and little influence on the waterproof structure of the building.Therefore,it has its unique advantages and applicability.But with regard to the bearing body of the pressure-type anchor,there is no uniform standard about the bearing body in the current norms or atlases.This brings about negative influences on the design and construction of pressure-type anchors.This paper takes actual building projects as the example and tries to optimize the bearing body of pressure type anti-floating anchors in accordance to the design requirements and relevant norms.The steel plate is taken as the core component of the improved bearing body to facilitate processing and field use as a guide and the traditional T-type anchor design is changed to U-type.The resulting good effect in the concrete engineering application provides a successful example for the popularization and application of the pressure type anchor bolt bearing body.
