[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The embodiment of the present application discloses a double-sided composite shear wall structure.

[0019] Reference Figure 1 and Figure 2The double-sided composite shear wall structure includes a first shear wall panel 1 and a second shear wall panel 2. A plurality of steel cages 3 are fixedly arranged between the first shear wall panel 1 and the second shear wall panel 2. The plurality of steel cages 3 are equidistantly and vertically arranged between the first shear wall panel 1 and the second shear wall panel 2. The steel cages 3 include a group of first steel frames 31 vertically arranged between the first shear wall panel 1 and the second shear wall panel 2 and two groups of second steel frames 32 vertically arranged in the first shear wall panel 1 and the second shear wall panel 2. There are four roots in total in the two groups of second steel bars 32, which are respectively located on both sides of the first steel bar frame 31, and the two groups of second steel bars 32 are respectively cast in the first shear wall panel 1 and the second shear wall panel 2, and the first steel bar frame 31 and the second steel bar frame 32 are connected in a hexagonal shape; a plurality of connecting steel bars 34 are transversely fixedly connected between the first steel bar frame 31 and the second steel bar frame 32, so the connection shape of the steel cage 3 is a hexagon, which makes the supporting structure of the first shear wall panel 1 and the second shear wall panel 2 relatively stable.

[0020] Reference Figure 3 The two groups of second steel bars 32 are both welded with support frames 33, and the two groups of support frames 33 are respectively fixedly connected to the steel bars in the first shear wall panel 1 and the second shear wall panel 2. This arrangement is convenient for fixing the steel cage 3 between the first shear wall panel 1 and the second shear wall panel 2 when casting the shear wall panel.

[0021] Reference Figure 3 A fixed block 4 is fixedly connected to the inner side of the first shear wall 31 near the upper end, and a shock-absorbing assembly 5 is fixedly connected to the upper surface of the fixed block 4. The shock-absorbing assembly 5 includes a shock-absorbing box 54 fixed to the upper surface of the fixed block 4. The shock-absorbing box 54 is a hollow square box with an upper end opening. A cover plate 51 is fixedly installed on the upper end of the shock-absorbing box 54. A first positioning hole 511 for the first steel bar frame 31 to pass through is opened at the center of the cover plate 51. Installing the cover plate 51 can reduce the entry of dust and debris into the shock-absorbing assembly 5 and affect the shock-absorbing performance of the shock-absorbing assembly 5; two sets of mounting platforms 52 are fixedly connected to both inner sides of the shock-absorbing box 54, and the two sets of mounting platforms 52 are fixedly installed in parallel on the shock-absorbing On the inner wall of the box 54, a group of installation platforms 52 are fixedly connected to a cylindrical limit rod 53 in the middle position, and the limit rod 53 is vertically fixedly connected between the installation platforms 52; a positioning block 7 is arranged in the middle position between the two limit rods 53, and the positioning block 7 is longitudinally penetrated with a second limit hole 71 for the first steel bar frame to pass through; the lower end of the first steel bar frame 31 between the first shear wall panel 1 and the second shear wall panel 2 of the upper layer is fixedly passed through the upper end of the positioning block 7, and the upper end of the first steel bar frame 31 between the first shear wall panel 1 and the second shear wall panel 2 of the lower layer is fixedly passed through the lower end of the positioning block 7, so that the first steel bar frames 31 of the upper and lower layers are fixed.

[0022] Reference Figure 3The limit rod 53 is provided with a connecting assembly 6, and the connecting assembly 6 is slidably connected to the limit rod 53. The connecting assembly 6 includes a connecting block 61 that is slidably sleeved on the limit rod 53. The connecting block 61 is cylindrical, and a spring 64 is fixedly connected to the lower end of the connecting block 61. One end of the spring 64 is fixedly connected to the bottom of the connecting block 61, and the other end is fixedly connected to the upper surface of the lower mounting platform 52. The two connecting blocks 61 are fixedly connected to an extension block 62 on one side close to the positioning block 7, and the extension block 62 is fixedly connected to the side away from the rotating block 61 with two connecting rods 63. The two connecting rods 63 are connected in an inclined manner, so that the two connecting rods 63 and the positioning block 7 form a triangle. The connecting block 61, the extension block 62 and the connecting rod 63 are an integrated workpiece, so that the connecting assembly 6 is more stable in the shock-absorbing box 54. ; Two sets of connecting shafts 8 are fixedly connected to the edges of both sides of the positioning block 7, and the connecting rods 63 are slidably sleeved on the connecting shafts 8. During an earthquake, the shear wall will shake in a direction perpendicular to the wall body, so the setting length of the connecting shaft 8 is sufficient to meet the displacement caused by the first steel frame 31 driving the positioning block 7 to shake; since a spring 64 is fixedly connected under the connecting block 61, the positioning block 7 is usually in the shock-absorbing box 54 with a distance from the upper and lower surfaces of the shock-absorbing box 54. When there is a vibration, the positioning block can be displaced to remove the force generated by the vibration, so that the upper and lower double-sided overlapping shear walls can withstand greater impact force when they are perpendicular to the wall body and laterally offset, making the installation structure more stable.

[0023] Installation steps: first put the prepared steel cage 3 into the shear wall panel mold, then cast the shear wall panel, after completion, let it stand and cure the wall panel, wait for the wall panel to be completed, then install the shock-absorbing device 5 on the first steel frame 31, and finally use a lifting machine to place the wall panel to the specified position and place the wall panel layer by layer.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
