The invention relates to the technical field of cement precast pile connection, in particular to a cement precast pile connecting piece and a construction method.The cement precast pile connecting piece comprises a connecting frame, four fastening plates distributed in a rectangular shape are arranged in the connecting frame, and the fastening plates are connected with the connecting frame through fastening bolts; a carbon fiber net is laid on the inner side of the connecting frame, a layer of bonding glue is smeared in meshes of the carbon fiber net, and the carbon fiber net is formed by weaving carbon fiber tows with the diameter ranging from 0.5 mm to 1.2 mm. Connection between the cement precast piles is achieved through the new material carbon fibers, internal stress cannot be generated like welding connection, an embedded structure cannot be needed like mechanical connector connection, and the beneficial effects of being easy to construct and high in connection reliability are achieved.
本发明涉及水泥预制桩连接技术领域，具体为一种水泥预制桩连接件及施工方法，包括连接框架，所述连接框架内设有呈矩形分布的四块紧固板，紧固板通过紧固栓与连接框架连接；所述连接框架内侧铺设有碳纤维网，碳纤维网的网孔内涂抹有一层粘接胶，碳纤维网由直径为0.5mm‑1.2mm的碳纤维丝束编织而成。本发明通过采用碳纤维这种新材料实现水泥预制桩之间的连接，既不会像焊接连接一样产生内应力，也不会像机械接头连接一样需要预埋结构，具有施工简单、连接可靠性高的特点。
