[0032] Furthermore, the linkage mechanism includes a sliding track 9 provided on the top of the embedded plate 2 and spanning the connecting hole 21, and a pair of sliding doors 8 relatively slidably arranged on the sliding track 9 to achieve an openable and closable blocking of the connecting hole 21. A first card groove 81 is provided on opposite sides of the pair of sliding doors 8. When the pair of sliding doors 8 are closed, the two first card grooves 81 are docked to form a socket for inserting the front end of the positioning cone 1. The diameter of the socket is smaller than the diameter of the connecting hole 21, and the socket is connected to the connecting hole 21. Preferably, the locking mechanism includes a pair of clips 3 located on the relatively outer sides of a pair of sliding doors 8, and the inner sides of the tops of the pair of clips 3 are provided with second clip grooves 331 for clipping the rear end of the positioning cone 1. The middle part of the clip 3 is rotatably connected to the embedded plate 2, and the bottom of the clip 3 is inserted into the sliding rail 9. It should be noted that in this embodiment, when the front end of the positioning cone 1 passes through the socket and is inserted into the connecting hole 21, the bottom of the clip 3 slides relatively outward to be clamped between the corresponding sliding doors 8 and the ends of the sliding rail 9, and the pair of second clip grooves 331 are relatively clamped to the rear end of the positioning cone 1.

[0036] The present invention also provides a method for positioning and connecting an assembled shear wall, comprising the following steps:

[0037] Step 1: Provide the above-mentioned assembled shear wall positioning and connection device, and embed the positioning cone at the bottom of the upper shear wall and the embedded plate at the top of the lower shear wall;

[0038] Step 2: Lift the upper shear wall so that the positioning cone is above the embedded plate and the front end of the positioning cone is aligned with the connection hole;

[0039] Step 3: Press down the positioning cone, and drive the locking mechanism to close as the positioning cone is inserted into the connecting hole through the linkage mechanism, so as to lock the positioning cone after it is inserted into the connecting hole. Specifically, as the depth increases, the pair of sliding doors are opened, so as to squeeze and rotate the corresponding two buckles respectively until the two buckles clamp the positioning cone, and the clamping plate in the buckle is located below the limit ring, thereby limiting the displacement of the entire wall and achieving precise positioning of the upper assembled shear wall;

[0040] Step 4: Grout high-strength grouting material between the upper shear wall and the lower shear wall to complete the positioning connection.
