Bridge stay cable anchor cylinder pre-embedding positioning device and using method thereof
The invention provides a bridge stay cable anchor cylinder pre-embedding positioning device and a using method thereof. A BIM full three-dimensional design idea is adopted, the influence of factors such as the dead weight of an anchor cylinder, the structure of the anchor cylinder and the longitudinal and transverse gradient of the position where a stay cable anchor block is located is considered,and temporary structures are arranged below and on the two sides of an anchor backing plate at the bottom of the anchor cylinder and at certain positions of the front end of the anchor cylinder, so that the stay cable anchor cylinder on a cast-in-place box girder of a cable-stayed bridge is quickly and accurately positioned, and the problems that the anchor cylinder is inaccurate in positioning due to the fact that the dead weight is large, the length is long, and a large number of steel bars are welded to the surface, or the anchor cylinder is not firmly reinforced in the construction process, is prone to deviation and is influenced by the temperature are solved. The invention belongs to the field of constructional engineering.
本发明提供一种桥梁斜拉索锚筒预埋定位装置及其使用方法，采用BIM全三维设计思路，考虑锚筒自重、锚筒本身的结构构造、斜拉索锚块所在位置的纵横坡度等因素影响，通过在锚筒底部锚垫板的下方、两侧及锚筒前端一定位置设置临时结构，以实现斜拉桥现浇箱梁上斜拉索锚筒的快速准确定位，解决由于自重较大、长度较长、表面上已焊接大量钢筋的锚筒定位不准确、或因在施工过程中加固不牢易跑偏、受温度影响导致锚筒定位不准的问题。属于建筑工程领域。
