[0009] Further, vertical grooves are integrally formed on the opposite sides of the two control discs. Connecting rods are fixedly connected together above the front and rear inner surfaces of the two vertical grooves. The outer sidewalls of the two connecting rods are both rotatably connected with grips. Return torsion springs are sleeved on the outer sidewalls of the two connecting rods and in front of and behind the two grips.

Detailed implementation manners

[0027] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0028] According to one aspect of the present utility model:

[0029] As Figure 1 shown, through-type grouting grooves 27 are provided on the upper surfaces of both the upper steel plate 1 and the lower steel plate 2, and a plurality of reinforcing steel bars 28 are jointly arranged inside the upper steel plate 1 and the lower steel plate 2;

[0030] Concrete can be poured between the upper steel plate 1 and the lower steel plate 2 through the provided grouting groove 27, thereby forming an integral shear wall structure. Grouting can enhance the bonding force between the upper steel plate 1 and the lower steel plate 2 and the concrete, improve the overall bearing capacity and seismic performance of the shear wall. At the same time, the stiffness and strength of the shear wall can be significantly improved by the provided multiple reinforcing bars 28, making the shear wall more stable when bearing external forces. The multiple reinforcing bars 28 and the concrete act together to form a strong stress system. Under the action of an earthquake or other external forces, the multiple reinforcing bars 28 can resist the deformation and distortion of the shear wall and maintain the integrity and stability of the structure.

[0031] As Figure 1 shown, leveling rulers 29 are symmetrically and fixedly connected to the opposite sides of the two control plates 3;

[0032] The provided multiple leveling rulers 29 can ensure that the two control plates 3 are in a horizontal state during the installation process. During the splicing process of the steel plate concrete shear wall, the levelness of the two control plates 3 is crucial for the stability and accuracy of the entire wall. Through the multiple leveling rulers 29, the horizontal positions of the two control plates 3 can be monitored and adjusted in real time to ensure the accuracy and reliability of the splicing joints.

[0033] As Figure 1 shown, front reinforcing plates 4 are integrally formed on the upper and lower surfaces of the two control plates 3. A plurality of through plug welding holes 30 are formed in the outer side walls of the multiple front reinforcing plates 4, and the outer side walls of the multiple front reinforcing plates 4 are in contact with the outer side walls of the upper steel plate 1 and the lower steel plate 2 respectively;

[0034] The multiple front reinforcing plates 4 are fixedly connected to the two control plates 3 by welding, thereby increasing the lateral force and other loads of the multiple front reinforcing plates 4 on the upper steel plate 1 and the lower steel plate 2. The multiple front reinforcing plates 4 can significantly improve the overall bearing capacity of the joints. Then, the two sides of the upper steel plate 1 and the lower steel plate 2 are reliably welded through the multiple plug welding holes 30. This not only improves the reliability of force transfer between the multiple front reinforcing plates 4 and the steel plate composite shear wall, but also saves construction time and improves the aesthetics of the steel plate composite shear wall. At the same time, the welded fixation of the multiple front reinforcing plates 4 can firmly fix the two control plates 3 at the splicing joint of the upper steel plate 1 and the lower steel plate 2, making the splicing of the upper steel plate 1 and the lower steel plate 2 more stable.

[0035] As Figures 1-3As shown in the figure, a splicing joint of a steel plate concrete shear wall is provided, which includes an upper steel plate 1 and a lower steel plate 2. The lower surface of the upper steel plate 1 is in contact with the upper surface of the lower steel plate 2. Control plates 3 are arranged on the left and right sides of the outer side walls of the upper steel plate 1 and the lower steel plate 2. The front surface and the rear surface inside the two control plates 3 are both rotatably connected by a rotating shaft to a bidirectional threaded rod 5. The outer side walls of the two bidirectional threaded rods 5 are symmetrically threadedly connected with moving plates 6. The plurality of moving plates 6 are respectively slidably connected inside the two control plates 3. The front surface and the rear surface inside the two control plates 3 are both provided with through extending grooves 7. One side of the plurality of moving plates 6 close to the plurality of extending grooves 7 is fixedly connected with telescopic splicing plates 8. The opposite sides inside the two control plates 3 are both provided with through sliding round holes 9. Inside the two sliding round holes 9, control discs 10 are rotatably connected. The centers of the opposite sides of the two control discs 10 are both fixedly connected with worm gears 11. The opposite ends of the two worm gears 11 are respectively rotatably connected to the opposite sides inside the two control plates 3 through a rotating shaft. The outer side walls of the two bidirectional threaded rods 5 and below the two worm gears 11 are both fixedly connected with worm wheels 12. The outer side walls of the two worm gears 11 are respectively meshed with the outer side walls of the two worm wheels 12;

[0036] When it is necessary to adjust the position or tightness of the splicing joint, first rotate the two control discs 10. The rotation of the two control discs 10 drives the two worm gears 11 to rotate. The meshing of the two worm gears 11 and the two worm wheels 12 causes the two bidirectional threaded rods 5 to start rotating. Thus, the rotation of the two bidirectional threaded rods 5 causes the two moving plates 6 on their outer sides to move in opposite directions, and further drives the two telescopic splicing plates 8 to extend or retract, so as to realize the precise adjustment of the splicing joint of the steel plate concrete shear wall. Since the two bidirectional threaded rods 5 have self-locking property and can keep their positions unchanged when not affected by external forces, the two sides of the steel plate concrete shear wall can be clamped by adjusting the plurality of telescopic splicing plates 8.

[0037] As Figure 1 and Figure 6 shown in the figure, one side of the plurality of telescopic splicing plates 8 away from the plurality of moving plates 6 respectively passes through the plurality of extending grooves 7 and extends to the front and rear of the two control plates 3 respectively. On the left side of the two telescopic splicing plates 8 on the right side and on the opposite sides of the upper steel plate 1 and the lower steel plate 2, side splicing plates 13 are integrally formed. Docking grooves 14 are opened on the opposite sides of the two side splicing plates 13. Rubber pads 15 are fixedly connected to the inner side walls of the two docking grooves 14. On the right side of the two telescopic splicing plates 8 on the left side and on the opposite sides of the upper steel plate 1 and the lower steel plate 2, pressing plates 16 are integrally formed. The two pressing plates 16 are both located inside the two docking grooves 14. Side reinforcing plates 17 are integrally formed on the upper surface and the lower surface of the two side splicing plates 13. A plurality of through plug welding holes two 18 are opened on the outer side walls of the plurality of side reinforcing plates 17. The outer side walls of the plurality of side reinforcing plates 17 are respectively in contact with the front surface and the rear surface of the upper steel plate 1 and the lower steel plate 2;

[0038] When the multiple telescopic splicing plates 8 are controlled to contract into the interiors of the two control plates 3 by rotating the two control discs 10, that is, the two side splicing plates 13 and the two pressing plates 16 are simultaneously driven to move by the multiple telescopic splicing plates 8 until the two side splicing plates 13 are in close contact between the front side and the rear side of the splicing seams of the upper steel plate 1 and the lower steel plate 2, and at the same time the two pressing plates 16 move into the interiors of the two docking grooves 14, the fixation and sealing of the splicing joints can be achieved, so that the joints maintain a certain stability. At the same time, in this way, shear walls with different widths can be fixed in real time, improving the flexibility and practicality of the device. Through the multiple plug welding holes two 18 provided, the multiple side reinforcing plates 17 can be quickly welded in front of and behind the upper steel plate 1 and the lower steel plate 2, so as to transfer and disperse the forces in front of and behind the shear wall through the multiple side reinforcing plates 17, ensuring that the splicing joints can maintain overall stability when bearing external loads.

[0039] As Figure 5 shown, transverse limiting grooves 23 are provided on the lower surfaces of the multiple telescopic splicing plates 8, guide rods 24 are fixedly connected to the front surfaces and the rear surfaces inside the multiple transverse limiting grooves 23, fixing blocks 25 are slidably connected to the outer side walls of the multiple guide rods 24, and the lower surfaces of the multiple fixing blocks 25 are fixedly connected to the upper surfaces inside the multiple protruding grooves 7 respectively;

[0040] By providing the multiple guide rods 24 and the multiple fixing blocks 25, during the movement of the multiple telescopic splicing plates 8, it is ensured that they can only slide along a predetermined horizontal direction, preventing deviation or inclination caused by uneven force or external factors, so that the multiple telescopic splicing plates 8 can have better load-bearing capacity and stability, providing a strong guarantee for the overall safety of the high steel plate concrete shear wall.

[0041] As Figure 2 and Figure 3 shown, limiting baffles 26 are symmetrically and fixedly connected above and below the two worm wheels 12 on the upper surface and the lower surface inside the two control plates 3;

[0042] By providing the multiple limiting baffles 26, the specific extension of the multiple telescopic splicing plates 8 can be effectively limited, and at the same time, the worm 11 and the worm wheel 12 can be protected from direct impact or excessive extrusion, thereby prolonging their service life and improving the stability and reliability of the device.

[0043] As Figure 3 and Figure 4As shown, vertical grooves 19 are integrally formed on the opposite sides of the two control discs 10. Connecting rods 20 are fixedly connected above the front and rear inner surfaces of the two vertical grooves 19. Grips 21 are rotatably connected to the outer side walls of the two connecting rods 20. Return torsion springs 22 are sleeved on the outer side walls of the two connecting rods 20 and in front of and behind the two grips 21. The two ends of the multiple return torsion springs 22 are fixedly connected to the front and rear surfaces of the two grips 21 and the opposite sides inside the two vertical grooves 19 respectively;

[0044] The two grips 21 provided facilitate the user to directly operate the two control discs 10. By rotating the two grips 21, the user can easily drive the rotation of the two control discs 10, thereby controlling the rotation of the worm 11 and the movement of the bidirectional threaded rod 5, making the operation more convenient and intuitive. At the same time, through the multiple return torsion springs 22 provided, when the two grips 21 are rotated to a certain position, the multiple return torsion springs 22 will store a certain amount of elastic potential energy. When the external force disappears (such as when the user releases the grips 21), the multiple return torsion springs 22 will release the stored elastic potential energy, causing the two grips 21 to automatically return to the initial position, which not only improves the convenience of operation but also avoids potential safety hazards caused by improper positions of the two grips 21.

[0045] Of course, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention also belong to the protection scope of the present invention.
