Embodiment 1
[0039] see figure 2 , a prestressed prefabricated concrete node curved surface connection structure, including a prefabricated column 1, a left prefabricated beam 2-1, a right prefabricated beam 2-2, a left node outrigger 6-1, and a right node outrigger 6-2; The left node outrigger 6-1 and the right node outrigger 6-2 are symmetrically arranged on the left and right sides of the prefabricated column 1, and the left node outrigger 6-1, the right node outrigger 6-2 and the precast column 1 Integral molding structure; the left node outrigger 6-1 is connected with the left prefabricated beam 2-1, and the right node outrigger 6-2 is connected with the right prefabricated beam 2-2;
[0040] The outrigger 6-1 at the left node and the outrigger 6-2 at the right node are variable-section structures. The end face of the beam connection is concave;
[0041] The connecting end surface of the left prefabricated beam 2-1 and the left node outrigger 6-1 is a convex surface, which is equal...
Embodiment 2
[0046] see image 3 , taking a single-story single-span planar frame structure as an example. A prestressed prefabricated concrete node curved surface connection structure, including a left prefabricated column 1-1, a right prefabricated column 1-2, a left node outrigger 6-1, a right node outrigger 6-2 and a prefabricated beam 2, left The precast column 1-1 is connected to one end of the precast beam 2 through the left node outrigger 6-1, and the right precast column 1-2 is connected to the other end of the precast beam 2 through the right node outrigger 6-2; the left precast column 1 -1 is integrally formed with the left node outrigger 6-1, and the right prefabricated column 1-2 is integrally formed with the right node outrigger 6-2;
[0047] The outriggers at the left and right nodes are of variable cross-section structure, the cross-section at the connection with the left and right prefabricated columns is large, the cross-section at the connection with the prefabricated b...
