Prefabricated segmented bent cap
A prefabricated segmented bent cap comprises a jig frame and segmented bent cap bodies, the segmented bent cap bodies which are oppositely arranged are placed on the jig frame, a wet connection section is formed between the oppositely arranged segmented bent cap bodies, the segmented bent cap bodies are composed of steel bars and concrete, and the segmented bent cap bodies are formed by connecting a plurality of segmented bodies. Mechanical sleeves connected with each other are arranged between the adjacent segmented bodies, and mechanical sleeves connected with the segmented bent cap bodies are also arranged at the wet connection section; and a grouting sleeve and a prestressed steel strand group are arranged in the segmented bent cap bodies, the grouting sleeve is arranged at the bottoms of the segmented bent cap bodies, and the prestressed steel strand group is arranged in the length direction of the segmented bent cap bodies. Compared with the prior art, by using the prefabricated segmented bent cap, the prestressed channels which are parallel to one another and extend in the stress direction of the bent cap are inserted before concrete is poured, prestressed steel strands are arranged in the prestressed channels, fixed through the P anchors at the two ends and tensioned to the specified length through the jacks, and the segmented bent cap is suitable for large bent cap construction.
一种预制分节盖梁，包括胎架和分节段盖梁，胎架上放置有相对设置的分节段盖梁，且相对设置的分节段盖梁之间形成有湿接段，分节段盖梁由钢筋和混凝土组成，所述分节段盖梁由若干段分段体连接而成，相邻分段体之间设有相连接的机械套筒，且湿接段处也设有与分节段盖梁相连接的机械套筒；所述分节段盖梁内设有灌浆套筒和预应力钢绞线组，灌浆套筒设置于分节段盖梁底部，预应力钢绞线组沿分节段盖梁的长度方向进行设置；与现有技术相比，在混凝土浇筑前穿插沿盖梁受力方向延伸的若干互相平行预应力通道，在预应力通道内设有预应力钢绞线，通过两端P锚固定，并通过千斤顶张拉至指定长度，适用于大型盖梁施工。
