Abstract

In this study, a new anchorage used for reconstructive engineering of pre-stressed structure is mainly introduced. Pre-stressed concrete structures began to appear at the end of the 19th century. The structure form of pre-stressed concrete expresses outstanding advantages and gets a wide application, no matter in the functional form or structural properties as well as in construction or investment benefit. Facing functional changes and a situation that structure opening is often inevitable on the floor; the ordinary anchorage cannot fully meet the requirements of the reconstructive engineering. It`s urgent to test the new anchorage whose outstanding characteristic is higher anchoring coefficient, separated anchoring cup, participating of retaining bolt. Combined with several data analysis of anchorage test, a comprehensive study of the anchorage is indispensable to explore the feasibility of engineering applications.
