[0019] The following is combined with Figure 1 To Attachment Figure 4 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0020] A multi-layer spliced ​​wall comprises a first wall 1, a second wall 2, a third wall 3 and a foundation 9 which are attached to each other. According to the different positions of the first wall 1, the second wall 2 and the third wall 3 on the building, the wall can be divided into the following four embodiments.

[0021] Embodiment 1, refer to the attached Figure 1 , this embodiment is a connection method of walls between two adjacent floors of buildings in a building structure.

[0022] In this embodiment, the first wall 1 is defined as a wall panel, the second wall 2 is defined as a floor slab, and the third wall 3 is defined as a wall panel. The first wall 1 is arranged below the second wall 2, and the third wall 3 is arranged above the second wall 2, and the adjacent surfaces of the first wall 1, the second wall 2 and the third wall 3 are mutually attached. A reserved sleeve 5 is arranged at one end of the first wall 1 close to the second wall 2 (i.e. the top of the first wall 1), and a reserved iron box 6 is arranged at one end of the third wall 3 close to the second wall 2 (i.e. the bottom of the third wall 3), and the second wall 2 is provided with a reserved connection hole 4, which is through. The first wall 1, the second wall 2, and the third wall 3 are fixed by a connecting rod 7, and the connecting rod 7 is a steel bar with a thread. One end of the connecting rod 7 is inserted into the reserved sleeve 5, and the other end of the connecting rod 7 passes through the connecting hole 4 and extends into the reserved iron box 6 to be locked with a nut 8. After the nut 8 is locked with the connecting rod 7, the reserved iron box 6 is filled with cement, and at the same time, the gap between the connecting hole 4 and the first wall 1 or the third wall 3 is filled with micro-expansion mortar to ensure the firmness of the connection between the first wall 1, the second wall 2 and the third wall 3.

[0023] Embodiment 2, refer to the attached Figure 2 In the first embodiment, a second wall 2 is disposed between the first wall 1 and the second wall 3; in the present embodiment, two second walls 2 are disposed between the first wall 1 and the second wall 3. It should be noted that a gap of about 5 mm should be left between the two second walls 2.

[0024] Embodiment 3, refer to the attached Figure 3 This embodiment is a fixed connection method between the parapet wall and the wall of the top floor of a building in a building structure.

[0025] In this embodiment, the first wall 1 is defined as a wall panel, the second wall 2 is defined as a floor slab, and the third wall 3 is defined as a parapet.
