[0001] This utility model belongs to the field of building engineering quality testing technology, specifically, it relates to a device for testing the bonding strength of facing bricks. Background Technology

[0002] Facing bricks are widely used on building walls, floors and other parts. The strength of their adhesion to the base layer is directly related to the integrity of the building's appearance and its safety. As the service time increases, due to environmental factors, material aging and external forces, facing bricks may develop problems such as hollowing, loosening or even falling off. This not only affects the building's aesthetics but may also pose safety hazards to pedestrians or facilities. Therefore, it is essential to test the adhesion strength of facing bricks.

[0003] However, the existing tile bonding strength testing device uses a snap-fit ​​method to connect the tie rod and the standard block, which has an unstable problem. The threaded connection method requires removing the tie rod from the testing device, screwing the thread at the end of the tie rod directly into the standard block, and then reinstalling it into the device, which is a cumbersome operation.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the instability issues inherent in existing tile bonding strength testing devices that use a snap-fit ​​connection between the tie rod and the standard block, and the cumbersome process of removing the tie rod from the device, screwing the threaded end of the tie rod directly into the standard block, and then reinstalling it, the basic concept of this invention is as follows:

[0006] A device for testing the bonding strength of decorative bricks includes a base, a support plate, a drive unit, a pull rod, and a standard block. The bottom of the pull rod is connected to a slide rod, and a connecting ring is movably sleeved on the slide rod. The connecting ring has an internal thread, and a positioning post is provided at the end of the slide rod. A connecting block is provided on the standard block, and a positioning hole adapted to the positioning post and an external thread adapted to the internal thread of the connecting ring are provided on the connecting block. Several suction cups are evenly distributed on the bottom of the support plate.

[0007] In a preferred embodiment of this utility model, the slide rod and the pull rod are coaxially fixedly connected, the outer diameter of the slide rod is smaller than the outer diameter of the pull rod, and the inner diameter of the end of the connecting ring is adapted to the outer diameter of the slide rod.

[0008] In a preferred embodiment of this utility model, the positioning post and the slide rod are coaxially fixedly connected, the outer diameter of the positioning post is larger than the outer diameter of the slide rod, and the inner diameter of the positioning hole is adapted to the outer diameter of the positioning post.

[0009] In a preferred embodiment of this utility model, the connecting block and the standard block are fixedly connected, the external thread on the connecting block is provided on the outer peripheral surface of the connecting block, and the positioning hole is opened along the axial direction of the connecting block, and the depth is adapted to the height of the positioning post.

[0010] In a preferred embodiment of this utility model, two support plates are provided below the base, and weight reduction holes are provided on both support plates.

[0011] In a preferred embodiment of this utility model, the base is provided with a display.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention optimizes the connection method between the pull rod and the standard block. The pull rod and the standard block are positioned by positioning pins and fastened by threaded connecting rings. This avoids the instability of traditional snap-fit ​​connections and allows the connection to be completed without disassembling the pull rod, simplifying the operation and improving the efficiency and reliability of the test. Furthermore, the addition of a suction cup at the bottom of the support plate can assist in stabilization, reducing the operational burden and ensuring stable and accurate testing.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 5 As shown, a device for testing the bonding strength of decorative bricks includes a base 1, a support plate 3, a drive unit 5, a pull rod 4, and a standard block 7. A slide rod 8 is connected to the bottom of the pull rod 4. A connecting ring 6 is movably sleeved on the slide rod 8. An internal thread 11 is provided on the connecting ring 6. A positioning post 10 is provided at the end of the slide rod 8. A connecting block 12 is provided on the standard block 7. A positioning hole 13 adapted to the positioning post 10 and an external thread 14 adapted to the internal thread 11 of the connecting ring 6 are provided on the connecting block 12. Several suction cups 15 are evenly distributed on the bottom of the support plate 3. In this setup, the base 1 is the basic load-bearing component of the device, the support plate 3 supports the base 1, and several suction cups 15 at its bottom can adsorb the device onto the base surface to ensure stability during testing. The drive unit 5 provides power for testing and can drive the pull rod 4 to apply tension. The pull rod 4 is the main component for transmitting tension, and its bottom slide rod 8 is used to connect the standard block 7. The connecting ring 6 movably sleeved on the slide rod 8 engages with the external thread 14 of the connecting block 12 on the standard block 7 through the internal thread 11, realizing a stable connection between the pull rod 4 and the standard block 7. The standard block 7 is pasted on the decorative brick to transmit tension to the decorative brick. The positioning hole 13 on the connecting block 12 is adapted to the positioning post 10 at the end of the slide rod 8 to play a role in precise positioning.

[0024] like Figures 1 to 5 As shown, in a specific embodiment, the slide rod 8 and the pull rod 4 are coaxially fixedly connected. The outer diameter of the slide rod 8 is smaller than the outer diameter of the pull rod 4, and the inner diameter of the end of the connecting ring 6 is adapted to the outer diameter of the slide rod 8. In this configuration, the slide rod 8 and the pull rod 4 are coaxially fixedly connected, and the outer diameter of the slide rod 8 is smaller than the outer diameter of the pull rod 4, which facilitates the fitting of the connecting ring 6. The inner diameter of the end of the connecting ring 6 is adapted to the outer diameter of the slide rod 8, ensuring that the connecting ring 6 can move stably on the slide rod 8 and cooperate with the connecting block 12.

[0025] like Figures 1 to 5 As shown, furthermore, the positioning post 10 and the slide rod 8 are coaxially fixedly connected. The outer diameter of the positioning post 10 is larger than the outer diameter of the slide rod 8, and the inner diameter of the positioning hole 13 is adapted to the outer diameter of the positioning post 10. In this configuration, the positioning post 10 and the slide rod 8 are coaxially fixedly connected, and its outer diameter is larger than the outer diameter of the slide rod 8 and is adapted to the inner diameter of the positioning hole 13 on the connecting block 12. This not only achieves precise positioning of the slide rod 8 and the connecting block 12, but also prevents the connecting ring 6 from falling off the slide rod 8, ensuring the stability of the connection.

[0026] like Figures 1 to 5As shown, the connecting block 12 and the standard block 7 are fixedly connected. The external thread 14 on the connecting block 12 is provided on the outer peripheral surface of the connecting block 12. The positioning hole 13 is opened along the axial direction of the connecting block 12, and its depth is adapted to the height of the positioning post 10. In this configuration, the connecting block 12 and the standard block 7 are fixedly connected. The external thread 14 on its outer peripheral surface cooperates with the internal thread 11 of the connecting ring 6 to achieve the connection with the pull rod 4. The depth of the positioning hole 13 opened along the axial direction is adapted to the height of the positioning post 10, ensuring that the positioning post 10 can be accurately positioned after insertion, and ensuring the coaxiality of the tensile force transmission.

[0027] like Figures 1 to 5 As shown, furthermore, two support plates 3 are provided below the base 1, and each support plate 3 has a weight-reducing hole 9. In this configuration, the two support plates 3 below the base 1 are used to support the detection device. The weight-reducing holes 9 on the support plates 3 reduce the overall weight of the device while ensuring the support strength, making it easier to operate and move.

[0028] like Figures 1 to 5 As shown, a display 2 is further provided on the base 1. In this setup, the display 2 on the base 1 is used to display relevant data during the testing process in real time, facilitating observation and recording by operators, and improving the convenience of testing and the accuracy of data reading.

[0029] The implementation principle of the facing brick bonding strength testing device in this embodiment is as follows: When using this device to test the bonding strength of facing bricks, firstly, a region of the same size as the standard block 7 is cut out in advance on the facing brick to be tested. The standard block 7 is then firmly fixed in this region by means of adhesive or other methods. After the adhesive is firmly attached, ensure that all components of the device are installed in place. Then, the device is firmly attached to the base surface of the facing brick to be tested by the suction cup 15 on the support plate 3 below the base 1 to prevent displacement during testing. Next, the positioning post 10 at the end of the bottom slide rod 8 of the pull rod 4 is inserted into the positioning hole 13 of the connecting block 12 on the standard block 7, and then rotated... The connecting ring 6, which is sleeved on the slide rod 8, engages with the internal thread 11 of the connecting block 12 and tightens it to achieve a stable connection between the standard block 7 and the pull rod 4. Finally, the drive unit 5 is activated, which drives the pull rod 4 to apply upward pulling force (this drive unit is existing technology and will not be described in detail here). The pulling force is transmitted to the standard block 7 and acts on the decorative brick. At this time, a force is generated between the support plate 3 and the decorative brick to be tested, which allows the suction cup 15 to adhere more tightly to the decorative brick, ensuring the stability of the testing device. The operator reads the test data in real time through the display 2 on the base 1 to complete the test.
