HAO SU / ZHOU YINGXIN / LI WANHENG / ZHANG JINGQUAN

The invention relates to the field of building bridge construction, and discloses a connecting structure for a concrete member. The connecting structure comprises a concrete member, wherein at least one V-shaped buffer cavity (3) is prefabricated in the concrete member, and the concrete member at least comprises a first concrete member (1) and a second concrete member (2); and a rod piece (4) which is used for connecting the first concrete member and the second concrete member, wherein the rod piece penetrates through the at least one V-shaped buffer cavity; wherein the connecting ends of therod piece are fixed to the first concrete member and the second concrete member respectively, and prestress can be applied to the connected concrete components in the axis direction of the rod piece.The disclosed connecting structure can be used for the connection and prestress application of a plurality of intersecting main force-bearing structural members; the technical problems that under thehigh external load working condition, stress concentration is conducted on the intersection joints of structural parts, so that large deformation of connecting rod pieces or prestressed steel strandsis caused in a stress concentration area, the whole structure exceeds unrecoverable distortion specified by the industry specification, and the connecting rod pieces or the prestressed steel strands are likely to be sheared off are solved.

本发明涉及建筑桥梁施工领域，公开了一种用于混凝土构件的连接结构，包括，混凝土构件，混凝土构件中预制至少一个V型缓冲腔(3)；混凝土构件至少包括第一混凝土构件(1)和第二混凝土构件(2)；杆件(4)，对第一混凝土构件和第二混凝土构件进行连接，杆件贯穿至少一个V型缓冲腔；其中，杆件的连接端分别固定在第一和第二混凝土构件上，并可以沿杆件的轴线方向对连接的混凝土构件施加预应力；所公开的连接结构可用于包括多个相交主要承力结构件的连接和施加预应力；解决由于在较高外载工况下这类结构件相交节点处应力集中导致的连接杆件或预应力钢绞线在应力集中区域大变形造成结构整体超出行业规范规定的不可恢复畸变和连接杆件或预应力钢绞线可能被剪断的技术问题。
