M1L15-1,M2L15-1  couplers can be used as anchorage firstly and as coupler later,  and are developed according to the practical needs of post-tensioned large concrete structures and research on existing products.The design process of couplers is introduced in detail on their basic structure, working principle and usefulness in construction, then the technical significance and the economical benefits of using them in super-long prestressed concrete continual structures are analyzed in many aspects, at last the testing results of prestressing tendon-coupler assembly are shown and explained
with the data and the curves.
Keywords: anchorage-coupler; prestressed tendons; clip piece anchorage; super-long prestressed concrete continual structures; test; prestressing tendon-anchorage assembly
