［摘要］按全截面連接、帶企口連接、借助懸挑預(yù)埋部件連接梳理國內(nèi)外預(yù)應(yīng)力混凝土雙T板端部連接方式的各種構(gòu)造和研究進展，分析了各連接方式的特點及優(yōu)缺點。在此基礎(chǔ)上提出了一種新型鋼質(zhì)企口連接方式，對其特點及設(shè)計要點、受力性能進行了分析,并對工程應(yīng)用的相關(guān)問題進行了探索。新型鋼質(zhì)企口連接的傳力路徑明確、設(shè)計及施工便捷，可為預(yù)應(yīng)力混凝土雙T板的推廣應(yīng)用提供有力保證。

Abstract:According to the full cross-section connection and dapped end connection, with overhanging embedded components connection, the various structures and research progress about the end connection mode of prestressed concrete double tees at home and abroad were reviewed, and the characteristics and advantages and disadvantages of each connection mode were analyzed. On this basis, a new steel dapped end connection mode was proposed, its features, design points and mechanical properties were analyzed, and related issues of engineering application were explored. The structure with new steel dapped end connection has clear transmission path, convenient design and construction, which can provide strong guarantee for the popularization and application of prestressed concrete double tees.
Keywords:prestress; concrete double tees; assembled building; steel dapped end
