U-shaped precast beam-column joint structure and construction method thereof
The invention relates to the technical field of fabricated buildings, in particular to a U-shaped precast beam-column joint structure and a construction method thereof.The U-shaped precast beam-column joint structure comprises a first precast column, a precast joint and a U-shaped precast beam, brackets are arranged on the two sides of the first precast column, and the ends of the U-shaped precast beam are placed on the brackets; a steel reinforcement framework is pre-buried in the U-shaped precast beam, and post-pouring concrete is poured in a U-shaped groove of the U-shaped precast beam. A plurality of additional steel bars are arranged on the prefabricated joint in a penetrating mode, and the two ends of each additional steel bar extend into the post-pouring concrete on the two sides of the prefabricated joint respectively and are in indirect lap joint with the steel bar framework. According to the embodiment, the additional steel bar is arranged on the prefabricated joint in a penetrating mode, and the two ends of the additional steel bar extend into the post-pouring concrete in the U-shaped grooves of the U-shaped prefabricated beams on the two sides correspondingly and are in indirect lap joint with the U-shaped prefabricated beam steel bar framework; the problems that construction is difficult, the joint quality cannot be guaranteed and the construction period is long due to the fact that beam bottom longitudinal bars directly stretch into the joint core area for anchoring can be solved.
本发明涉及装配式建筑技术领域，具体涉及一种U形预制梁‑柱节点结构及其施工方法，包括第一预制柱、预制节点以及U形预制梁，第一预制柱的两侧均设置有牛腿，U形预制梁的端部搁置于牛腿上；U形预制梁中预埋有钢筋骨架，U形预制梁的U形槽内浇筑有后浇混凝土；预制节点上贯穿设置有若干附加钢筋，各附加钢筋的两端分别伸至所述预制节点两侧的后浇混凝土中，并与钢筋骨架间接搭接。本实施例通过在预制节点上贯穿设置附加钢筋，并将附加钢筋的两端分别伸至两侧的U形预制梁的U形槽中的后浇混凝土中并与U形预制的梁钢筋骨架间接搭接，可以避免梁底纵筋直接伸入节点核心区进行锚固造成施工困难、节点质量无法得到保证以及施工周期较长的问题。
