Concrete-filled steel tube pier column and bent cap fabricated joint
The invention belongs to the field of structural engineering, and relates to a concrete-filled steel tube pier column and bent cap fabricated joint. The fabricated joint is formed by assembling a prefabricated concrete-filled steel tube pier column and a reinforced concrete bent cap through a high-strength bolt and a post-tensioned prestressed steel bar. The post-tensioned prestressed steel bar islocated in the prefabricated concrete-filled steel tube pier column, the pier column is provided with an annular plate with stiffening grid plates at the assembling end, the prefabricated bent cap isprovided with bolt holes and prestressed rib holes, a high-strength steel embedded plate is embedded in the prefabricated bent cap, and the embedded plate is used for better assembling and anchoringthe high-strength bolt, the prestressed steel bar and the bent cap. In order to facilitate assembly and installation of the joint and reasonable stress, a space is reserved between the embedded plateand a high-strength steel cover plate; therefore, the fabricated joint can be opened and closed under the earthquake action, the rigidity of the fabricated joint is reduced, the natural vibration period is prolonged, and the purpose of shock absorption is achieved. Meanwhile, sustainable and industrial development of building-resources-environments is promoted. The fabricated joint can be appliedto important structures such as bridge engineering and subway engineering.
本发明属于结构工程领域，涉及一种钢管混凝土墩柱与盖梁装配式节点。所述装配式节点为预制钢管混凝土墩柱与钢筋混凝土盖梁之间通过高强螺栓和后张法预应力钢筋装配而成的节点。后张法预应力钢筋处于预制钢管混凝土墩柱之中，墩柱在装配端部带有加劲格板的环板，预制盖梁带有螺栓孔和预应力筋孔，以及在其中预埋高强钢嵌板，嵌板是为了更好地使高强螺栓和预应力钢筋与盖梁之间进行装配锚固，为了便于节点装配安装及受力合理，在嵌板与高强钢盖板之间留有空间；从而使该装配式节点能够在地震作用下张开与闭合，自身刚度减小，自振周期增加，达到减震的目的；同时也促进建筑‑资源‑环境可持续、工业化发展。可应用于桥梁工程、地铁工程等重要结构。
