Detachable prefabricated concrete beam-column joint
The invention provides a detachable prefabricated concrete beam-column joint which comprises a prefabricated concrete beam and a prefabricated concrete column, the top of the prefabricated concrete column is in linear contact with one end of the prefabricated concrete beam, and the prefabricated concrete beam and the prefabricated concrete column are perpendicularly distributed. A joint post-pouring area is formed at the contact position of the prefabricated concrete column and the prefabricated concrete beam, the joint post-pouring area is filled with thermal reversible ultra-high performance concrete, and the thermal reversible ultra-high performance concrete can be broken through low impact force after being heated. According to the fabricated joint part, the problem that a poured concrete member is difficult to break and disassemble can be solved in a heating mode, the overall integrity and reusability of a beam column member are guaranteed, the detachability of a post-poured concrete structure of the joint is achieved, and the post-poured joint is not prone to deformation. And the anti-seismic property of the prefabricated concrete structure is ensured.
本发明提供了一种可拆卸预制装配混凝土梁柱节点，包括预制混凝土梁和预制混凝土柱，所述预制混凝土柱的顶部与预制混凝土梁一端呈线接触，且预制混凝土梁与预制混凝土柱呈垂直分布，所述预制混凝土柱与预制混凝土梁的接触位置形成有节点后浇区域，所述节点后浇区域的内部填充有热可逆超高性能混凝土，所述热可逆超高性能混凝土在受热后可通过低冲击力进行破碎。本发明的装配式节点部位通过加热的方式，可以解决浇筑混凝土构件难以破碎拆解的问题，并且保证了梁柱构件的整体完整性和可重复使用性，实现了节点后浇筑混凝土结构的可拆卸性，而且，后浇筑的节点，保证了预制装配混凝土结构的抗震性能。
