It is connected, such as when the side wall of piping lane is connect with middle wall body, which can not just ensure it with enough bonding strengths
With good stress performance.
Utility model content
Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, offer is a kind of to realize that two is prefabricated
Sandwich wall is attached at vertical pivoting angle, and vertical with prefabricated sandwich wall turn of the prefabricated sandwich wall with enough stress performances
Angle connecting joint structure.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of vertical pivoting angle connecting joint structure of prefabricated sandwich wall and prefabricated sandwich wall is included at a vertical pivoting angle and connects
The the first prefabricated sandwich wall and the second prefabricated sandwich wall connect, the first prefabricated sandwich wall and the second prefabricated sandwich wall respectively include being located at
