Annular composite material structure hinge

The utility model relates to an annular composite material structure hinge, which is characterized in that a U-shaped cross connecting steel bar is reserved and extends into a reserved hole of a plate, the elastic connection between a column and the plate is realized through post-pouring slurry, an annular composite material gasket is fixed on a steel plate pre-buried at the top of the column through bonding glue, and a composite material gasket with a certain height is cast in situ inside the annular composite material gasket. Compared with traditional consolidation connection, the structurehinge is easy and convenient to construct, the rigidity effect of the connection structure can be reduced through the high elasticity of the annular composite material, and therefore the adverse effects of the temperature, shrinkage creep and other effects on the overall stress of the structure are reduced. 本实用新型专利涉及一种环状复合材料结构铰，预留U型交叉连接钢筋，伸入板的预留孔中，通过后浇灌浆料实现柱与板的弹性连接，环状复合材料垫片通过粘结胶固定在柱顶部预埋的钢板上，内部现浇一定高度的复合材料垫片。相比较于传统的固结连接，这种结
