Embodiment Construction
[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0033] Please refer to figure 1 An embodiment of the connection structure between the prefabricated sandwich wall and the middle laminated slab of the present invention includes an upper layer prefabricated sandwich wall 1 and a lower layer prefabricated sandwich wall 2 connected through the first node 6, and the lower layer prefabricated sandwich wall 2 is connected to the middle laminated slab through the second node 7 3. The upper and lower prefabricated sandwich walls 1 and 2 respectively include the first prefabricated layers 11 on both sides and the first cast-in-place layer 12 in the middle. The distributed tendons 4 perpendicular to the stressed tendons 5 and the truss tendons 9 for supporting the stressed tendons 5 are evenly arranged between the stressed tendons 5 in the first prefabricat...

Provided are a prefabricated sandwiched wall and middle superimposed board connecting structure and a construction method thereof. The connecting structure comprises an upper-layer prefabricated sandwiched wall and a lower-layer prefabricated sandwiched wall which are connected through a first node, wherein the lower-layer prefabricated sandwiched wall is connected with a middle superimposed boardthrough a second node, stress ribs of the upper-layer prefabricated sandwiched wall downward extend to enter the first node, and stress ribs of the lower-layer prefabricated sandwiched wall upward extend to enter the first node and extend to the bottom of a first prefabricated layer of the upper-layer prefabricated sandwiched wall. Stress ribs in a second cast-in-situ layer and a second prefabricated layer of the middle superimposed board respectively extend into the second node. The first node and the first cast-in-situ layer of the upper-layer prefabricated sandwiched wall are cast in situto form a first cast-in-situ section, and the second node, a first cast-in-situ layer of the lower-layer prefabricated sandwiched wall and a second cast-in-situ layer of the middle superimposed boardare cast in situ to form a second cast-in-situ section.
Description
technical field [0001] The invention relates to a fully prefabricated and assembled underground comprehensive pipe gallery, in particular to a prefabricated sandwich wall and intermediate laminated plate connection structure of a fully prefabricated and assembled underground comprehensive pipe gallery and a construction method thereof. Background technique [0002] Chinese patent application CN205742265U discloses a fully prefabricated laminated and assembled underground comprehensive pipe gallery. The base plate, side wall or side wall, the middle wall and the roof are connected by cast-in-place to form an integral underground comprehensive pipe gallery. The prefabricated sandwich wall includes prefabricated layers on both sides and a sandwich cast-in-place layer in the middle. The prefabricated layer of the prefabricated sandwich wall is pre-embedded with steel mesh, and the steel mesh in the prefabricated layer on both sides is connected by binding on the middle truss fi...
