[0032] This design not only provides a strong physical reinforcement effect, but also has intelligent perception and dynamic response capabilities, significantly improving the safety and durability of prefabricated buildings.

[0033] Example 2 like Figures 1 to 10As shown, this embodiment further describes the additional components and special structural features of the wall reinforcement device for assembled buildings based on the embodiment 1: The foam sealing plate 14 is fixedly connected between the fastening block 2 and the outer pressure plate 8 and the inner pressure plate 9. The toothed strip 15 is fixedly connected to the end where the outer pressure plate 8 and the inner pressure plate 9 are close to each other. The fixing groove of the connecting block 1 is opened at the end where the symmetrically arranged connecting blocks 1 are far away from each other, and cooperates with the wall.

[0039] Dynamic response stage: When the wall is subjected to external force, the wedge-shaped boss structure begins to play a role, providing preliminary force dispersion and buffering. If the external force continues to increase, the toothed strip 15 may contact the connecting block 1 to provide an additional locking mechanism. The arc-shaped structure of the outer pressure plate 8 and the inner pressure plate 9 will produce a slight deformation when under pressure, further absorbing the external force.

[0040] Enhanced sealing, the foam sealing plate 14 effectively fills the gap between the fastening block 2 and the pressure plate, improves the sealing of the entire device, prevents the intrusion of moisture and dust, and improves safety. The toothed pressure strip 15 can contact the connecting block 1 in extreme situations to form an additional locking mechanism to prevent device failure and improve the fixing effect. The fixing groove design on the connecting block 1 enhances the connection stability with the wall, improves the fixing effect of the overall device, and enhances the buffering capacity. The wedge-shaped boss structure on the connecting block 1, the outer pressure plate 8 and the inner pressure plate 9 can effectively disperse and buffer external impact forces, reduce direct damage to the wall, and improve adaptability. The mutual cooperation design of the wedge-shaped bosses allows installation Fine-tuning is performed during the installation process to improve the adaptability of the device to different wall conditions and enhance durability.

[0042] Example 3 like Figures 1 to 10 As shown, based on Examples 1 and 2, this example mainly describes the material properties and strain mechanism of the strain tube and the strain ring in the wall reinforcement device for assembled buildings: The material of the strain tube 4 is an electro-strictive material, and the strain direction is its radial direction.

[0043] The material of the strain tube 2 5 is piezoelectric material, and the strain direction is its radial direction.

[0044] The material of the strain ring 6 is piezoelectric material, and the strain direction is its axial direction.

[0045] The material of the strain ring 27 is an electro-strain material, and the strain direction is its axial direction.

[0046] Working process Static state: When there is no external force, all strain tubes and strain rings remain in their initial state.

[0047] Force sensing stage: When the wall is subjected to external force, the strain tube 2 5 and the strain ring 1 6 made of piezoelectric material first sense the stress change, the strain tube 2 5 produces a small deformation in the radial direction and a voltage change, and the strain ring 1 6 produces a small deformation in the axial direction and a voltage change.

[0048] Signal transmission stage: The voltage changes generated by the strain tube 2 5 and the strain ring 1 6 are transmitted to the strain tube 1 4 and the strain ring 2 7 through electrical connections.

[0049] Active response phase: After receiving the voltage signal, the strain tube 4 made of the electro-telescopic material generates telescopic deformation in the radial direction. After receiving the voltage signal, the strain ring 2 7 made of the electro-telescopic material generates telescopic deformation in the axial direction. These deformations act on the connecting block 1 and the fastening block 2, thereby affecting the positions of the outer pressure plate 8 and the inner pressure plate 9.

[0050] Dynamic adjustment stage: As the external force changes, the entire system continues the above process to achieve dynamic adjustment of the wall reinforcement state.

[0051] Data monitoring stage: During the whole process, the voltage changes of the strain tube and strain ring can be monitored and recorded in real time by an external system.

[0052] High sensitivity: the strain tube 2 5 and strain ring 1 6 made of piezoelectric material are highly sensitive to stress changes and can quickly detect small external forces on the wall. Fast response: the strain tube 1 4 and strain ring 2 7 made of electro-telescopic material can quickly respond to voltage signals to achieve instant adjustment of the wall reinforcement state. Bidirectional adjustment: through the combination of radial and axial strains, all-round adjustment of wall reinforcement is achieved, improving the reinforcement effect. Precise control: the deformation of the electro-telescopic material is proportional to the voltage signal, allowing precise control of the reinforcement strength. Dynamic adaptation: the system can dynamically adjust the reinforcement strength according to the real-time stress conditions and adapt to different external environmental changes. Energy conversion: piezoelectric materials convert mechanical energy into electrical energy, partially recovering the energy of external forces. , improves the energy efficiency of the system, self-check function, by monitoring the voltage changes of the strain tube and strain ring, the system can realize self-checking and discover potential problems in time, data acquisition, continuous voltage change recording provides valuable data support for building structure health monitoring, low power consumption, when there is no external force, the system is in a static state, and only very little energy is required to maintain the monitoring state, achieving low power consumption operation, long-term stability, the long service life of the electro-telescopic material and piezoelectric material ensures the long-term stable operation of the reinforcement system, non-linear compensation, the combined use of radial and axial strains helps to compensate for the nonlinear effects that may be caused by strain in a single direction, multi-scale response, the system can simultaneously cope with large-scale structural deformations and tiny vibrations, providing comprehensive wall protection.

[0053] This design of material properties and strain mechanism not only improves the sensing sensitivity and response speed of the device, but also realizes precise and dynamic adjustment of the wall reinforcement state, greatly enhancing the overall performance and adaptability of the device.

[0054] Example 4 like Figures 1 to 10 As shown, based on embodiments 1, 2 and 3, this embodiment describes in detail the installation and use method of the wall reinforcement device for assembled buildings, including the following steps: S1. Installation preparation: Make sure the wall surface is clean and flat, and mark the installation location.

[0055] The symmetrically arranged connection blocks 1 are fixedly connected between the walls, using a fixing method suitable for the wall material (such as expansion bolts or chemical anchor bolts).

[0056] S2. Component installation: Place two fastening blocks 2 between the two connecting blocks 1 to ensure that the fastening blocks 2 fit tightly with the connecting blocks 1 .

[0057] Put strain tube 1 4 , strain tube 2 5 , strain ring 1 6 and strain ring 2 7 into the fastening groove 3 on the fastening block 2 in sequence, paying attention to their correct installation sequence and direction.

[0058] The foam sealing plate 14 is attached to both ends of the fastening block 2 to ensure the sealing effect.

[0059] Carefully place the bidirectional solenoid 12 into the strain tube 2 5 to avoid damaging the strain tube.

[0060] S3. Press plate installation and adjustment: Align the outer threaded sleeve 10 and the inner threaded sleeve 11 on the outer pressure plate 8 and the inner pressure plate 9 and install them into the strain tube 2 5 .

[0061] Use a special tool to rotate the bidirectional screw tube 12, through the opposite thread directions of the outer screw sleeve 10 and the inner screw sleeve 11, and at the same time pull the outer pressure plate 8 and the inner pressure plate 9 together until the wall is pressed tightly.

[0062] The fastening bolt 13 is rotated into the bidirectional solenoid 12 and adjusted until the fastening bolt 13 contacts the inner pressure plate 9 to further fix the positions of the bidirectional solenoid 12 and the outer pressure plate 8 .

[0063] S4. System connection: Carefully check the electrical connections of strain tube 1 4 , strain tube 2 5 , strain ring 1 6 and strain ring 2 7 .

[0064] Electrically connect these components to the external monitoring system, ensuring the connections are secure and waterproof.

[0065] S5. Dynamic response: After the system starts working, it continuously monitors the wall status.

[0066] When the wall is impacted by external force, the voltage of the strain tube 2 5 and the strain ring 1 6 (piezoelectric material) changes.

[0067] The voltage change is transmitted to the strain tube 1 4 and the strain ring 2 7 (electrically stretched material), causing them to deform.

[0068] The deformation effect counteracts the movement of the wall and increases the fixing pressure.

[0069] At the same time, the wedge-shaped bosses on the outer pressure plate 8 and the inner pressure plate 9 cooperate with the wedge-shaped bosses at the outer ends of the connecting blocks 1 to buffer and absorb the impact.

[0070] S6. Safety monitoring: Through the external system, the strain data is monitored and recorded in real time to establish the wall stress history archive.

[0071] Check regularly whether the toothed strip 15 is in contact with the connecting block 1. If there are traces of contact, it indicates that the wall has been subjected to a large impact and needs to be inspected in detail.

[0072] According to the monitoring data and on-site inspection results, the fastening bolts 13 are adjusted when necessary to maintain the best fixing effect.

[0073] Installation flexibility, the step-by-step installation method allows flexible application on different types of walls and adapts to various building environments. Precise adjustment, through the cooperation of the two-way screw tube 12 and the fastening bolt 13, the precise control of the reinforcement strength is achieved. Sealing protection, the use of the foam sealing plate 14 enhances the dust and moisture resistance of the device and extends its service life. Dynamic response, the coordinated work of the strain tube and the strain ring enables the device to respond to the stress condition of the wall in real time and provide active protection. Buffer mechanism, the design of the wedge-shaped boss provides additional impact buffering capacity, reducing the damage to the wall caused by sudden strong force. Real-time monitoring, the connection with the external system enables the device to have real-time data collection and analysis capabilities, providing data support for building safety management, and predictive Alarm function, by continuously monitoring strain data, the system can promptly detect potential structural problems and achieve early warning. It is easy to maintain. The design of the toothed strip 15 enables maintenance personnel to quickly identify locations that have been subjected to large impacts, which is convenient for targeted inspections. It has strong adaptability and can adjust the fastening bolts 13 according to the monitoring data, so that the device can adapt to slight changes in the long-term use of the building. It is non-invasively installed, and the entire installation process has minimal impact on the original wall structure. It is suitable for the reinforcement and renovation of existing buildings.
