Novel fabricated beam joint and construction form thereof
The invention discloses a novel fabricated beam joint and a construction form thereof. The novel fabricated beam joint comprises a prefabricated main beam and cast-in-place ultrahigh-performance concrete. Bolt holes are reserved in the bottom and the bevel of the prefabricated main beam, the bolt holes are in penetrating connection in an upper hole and a lower hole in the prefabricated main beam.The vertical faces of the two sides of the prefabricated main beam are concave-convex faces, and U-shaped steel bars and stretching-out steel bars are reserved. In the prefabricated main beam, high-strength bolts penetrate through the four bolt holes in the vertical direction, finally the prefabricated main beam is fixed to an anchoring part on the beam surface to be connected with the anchoring part, the U-shaped steel bars and the stretching-out steel bars are used for connecting in the horizontal direction, namely, the concave-convex faces, and finally the cast-in-place ultrahigh-performance concrete is used on two main beam seams to achieve binding. The beam joint adopts the connecting manner of combining dry connecting and wet connecting, the advantages of the two connecting manners are achieved at the same time, the novel fabricated beam joint has the advantages of good integrity, ductility, anti-seismic property and the like, meanwhile, the assembly rate is relatively improved,and more efficient and energy-saving development of a fabricated building is promoted.
本发明公开了一种新型装配式梁节点及其施工形式，包括预制主梁和现浇超高性能混凝土，所述的预制主梁在底部和斜面处均预留有螺栓孔洞，所述螺栓孔洞在预制主梁内部上下孔洞贯穿连接，所述预制主梁在两侧的竖直面均为凹凸面，并预留有U形钢筋和外伸钢筋，所述预制主梁在垂直方向上使用高强螺栓贯穿4个螺栓孔洞最后在梁表面固定于锚固件相互连接，在水平方向即在凹凸面使用预留U形钢筋和外伸钢筋连接，最后在两个主梁接缝处用现浇超高性能混凝土进行粘结。该梁节点采用干、湿式连接相结合的连接方式，同时兼顾了两种连接方式的优点，具有较好的整体性、延性和抗震性能等特点，同时相对提升了装配率，促使装配式建筑更加高效节能的发展。
