Multi-wedge-shaped connecting joint for FRP rib of concrete structure and manufacturing method of multi-wedge-shaped connecting joint
The invention relates to the field of civil engineering, provides a multi-wedge-shaped connecting joint for a concrete structure FRP rib and a manufacturing method of the multi-wedge-shaped connecting joint, and aims to solve the problems that the shear strength between the structure of an existing multi-wedge-shaped connecting joint for the concrete structure FRP rib and the FRP rib is small, the length of the connecting joint needs to be increased when the connecting joint is used for connecting the FRP rib with the large diameter, and the connecting joint cannot be used for connecting the FRP rib with the large diameter. Therefore, the connection joint is not beneficial to the arrangement of the FRP ribs in the concrete structure. The multi-wedge-shaped connector comprises an inner pipe body and a sleeve, the inner pipe body is fixedly sleeved with the sleeve, a plurality of first wedge-shaped grooves are formed in the outer surface of the inner pipe body, the inner pipe body is connected with the inner surface of the sleeve in a matched mode through the first wedge-shaped grooves, a plurality of second wedge-shaped grooves are formed in the inner surface of the sleeve, and the second wedge-shaped grooves are connected with the inner surface of the sleeve in a matched mode through the second wedge-shaped grooves. The second wedge-shaped groove is connected with the outer surface of the inner pipe body in a matched mode.
本申请涉及土木工程领域，提供一种用于混凝土结构FRP筋的多楔形连接接头及其制造方法，以解决现有用于混凝土结构FRP筋的多楔形连接接头的结构与FRP筋之间的剪切强度小，在用于连接直径较大的FRP筋时需要较大延长连接接头的长度，从而导致该连接接头不利于FRP筋在混凝土结构中的排布的问题。所述多楔形连接接头包括内管本体和套管，所述套管固定套设在所述内管本体上，所述内管本体的外表面上设置有多个第一楔形槽，并通过所述第一楔形槽与所述套管的内表面相配连接，所述套管的内表面上开设有多个第二楔形槽，并通过所述第二楔形槽与所述内管本体的外表面相配连接。
