[0021] This utility model embodiment provides a device for testing the strength of interior wall foundations in building construction, such as... Figure 1-4 As shown, the building construction interior wall foundation strength testing device includes: a base 1; a limiting cylinder 2 fixed to the top of the base 1; a threaded cylinder 3 rotatably installed inside the limiting cylinder 2, wherein a first threaded rod 4 extending outside the threaded cylinder 3 is threadedly installed inside the threaded cylinder 3, and the threaded cylinder 3 cooperates with the first threaded rod 4 to adjust the height of the interior wall foundation strength testing; a support cylinder 5 installed on the top of the first threaded rod 4, wherein a rebound hammer body 6 for testing the wall strength is installed inside the support cylinder 5; and a limiting structure set on the support cylinder 5 for stabilizing the rebound hammer body 6.
[0022] In this embodiment, the base 1 provides a stable foundation support for the entire testing device, ensuring its stability during use. The combination of the limiting cylinder 2, the threaded cylinder 3, and the first threaded rod 4 achieves an adjustable testing height for indoor wall foundation strength, facilitating testing of walls at different heights and solving the problem of unstable rebound hammer operation when personnel are testing at heights. The support cylinder 5, used to install the rebound hammer body 6 (taking the ZC5 mortar rebound hammer as an example), provides a suitable installation position. The limiting structure stabilizes the rebound hammer body 6, ensuring stability during testing and reducing errors caused by shaking, thereby improving the accuracy and reliability of the test results and ensuring the smooth progress of indoor wall foundation strength testing in building construction.
[0023] In a further preferred embodiment of the present invention, the limiting structure includes a second threaded rod 7 threadedly mounted on the support cylinder 5, the second threaded rod 7 extending into the support cylinder 5; a clamping plate 19 rotatably mounted at the bottom of the second threaded rod 7 for clamping and stabilizing the rebound device body 6, the clamping plate 19 being equipped with an anti-slip pad 20 that contacts the rebound device body 6 to increase friction; and an adjusting block 8 fixed to the top of the second threaded rod 7 for providing an operating grip point.
[0024] In this embodiment, by setting the second threaded rod 7 to be threaded onto the support cylinder 5 and extending into the support cylinder 5, the position of the clamping plate 19 can be flexibly adjusted, facilitating the clamping operation of the rebound hammer body 6. By setting the clamping plate 19 rotatably installed at the bottom of the second threaded rod 7, the rebound hammer body 6 is clamped and stabilized, preventing the rebound hammer from shaking during the testing process. By installing the anti-slip pad 20 on the clamping plate 19 and contacting it with the rebound hammer body 6, the friction between the clamping plate 19 and the rebound hammer is increased, further improving the clamping stability. By setting the adjusting block 8 fixed at the top of the second threaded rod 7, a convenient operating grip point is provided for the operator, making the adjustment process easier and less strenuous, thereby improving the efficiency and accuracy of the testing work.
[0025] In a further preferred embodiment of the present invention, a connecting block 9 is installed on the top of the support cylinder 5, a spring 10 is fixed on the connecting block 9, and a cleaning brush 11 for cleaning the wall is fixed on the spring 10.
[0026] In this embodiment, by setting the connecting block 9 on the top of the support cylinder 5, a stable connection base is provided for the cleaning wall-related components. By fixing the spring 10 on the connecting block 9, the pressure of the cleaning brush 11 is buffered and adjusted, so that the cleaning brush 11 can adaptively adjust according to the flatness of the wall surface when it contacts the wall surface, avoiding damage to the wall surface or the cleaning brush 11 itself due to excessive pressure. By fixing the cleaning brush 11 on the spring 10, the wall surface can be cleaned with the cleaning brush 11 before testing the wall strength, removing dust, debris, etc., thereby ensuring that the rebound hammer body 6 makes full contact with the wall surface during testing, reducing the testing error caused by wall stains, improving the accuracy of the test results, and ensuring the smooth progress of the testing work.
[0027] In a further preferred embodiment of the present invention, a mounting plate 13 is detachably mounted on the top of the base 1, a guide frame 14 is fixed on the top of the mounting plate 13, and a locking plate 15 is hinged on the support cylinder 5 and movably sleeved on the guide frame 14. The guide frame 14 cooperates with the locking plate 15 to limit the lifting path of the support cylinder 5.
[0028] In this embodiment, by setting a detachable mounting plate 13 on the top of the base 1, the installation and disassembly of the guide frame 14 are facilitated, making it easier to assemble, maintain, and replace components of the device. By fixing the guide frame 14 on the top of the mounting plate 13, a guiding reference is provided for the lifting and lowering of the support cylinder 5. By hinged to the support cylinder 5 and movably sleeved on the guide frame 14, the guide frame 14 and the clamping plate 15 cooperate to limit the lifting and lowering path of the support cylinder 5, so that the support cylinder 5 can move stably along the predetermined path when adjusting the height, avoiding the support cylinder 5 from shaking or deviating during the lifting and lowering process, ensuring that the rebound hammer body 6 can accurately reach the designated detection position, improving the stability and accuracy of the detection work, and ensuring the smooth progress of the detection work.
[0029] In a further preferred embodiment of the present invention, a fixing bolt 16 is threadedly installed on the clamping plate 15 and threadedly connected to the support cylinder 5 for stabilizing the clamping plate 15. A ball bearing for reducing friction is embedded on the inner wall of the clamping plate 15, and the ball bearing is in contact with the guide frame 14.
[0030] In this embodiment, the fixing bolt 16 is threadedly installed on the clamping plate 15 and threadedly connected to the support cylinder 5, which stabilizes the clamping plate 15 and effectively prevents it from loosening or shifting during the lifting and lowering of the support cylinder 5. This ensures stable cooperation between the guide frame 14 and the clamping plate 15, thereby guaranteeing the accuracy of the lifting and lowering path of the support cylinder 5. By embedding ball bearings on the inner wall of the clamping plate 15 that contact the guide frame 14, the friction between the clamping plate 15 and the guide frame 14 is greatly reduced, making the lifting and lowering of the support cylinder 5 smoother. This reduces the resistance caused by friction, reduces component wear, extends the service life of the device, and improves the lifting and lowering efficiency of the support cylinder 5. This makes the entire testing device more flexible and convenient to operate, and improves the overall efficiency of the testing work.
[0031] In a further preferred embodiment of the present invention, the guide frame 14 is provided with a handle 17 for providing an operating grip point, the bottom of the base 1 is fixed with a mounting frame, and the mounting frame is rotatably mounted with a moving wheel 18 for assisting the movement of the equipment.
[0032] In this embodiment, by providing a glove 17 on the guide frame 14, a convenient gripping point is provided for the operator, which facilitates auxiliary operation of the guide frame 14 and its related structures when needed, such as adjusting the initial position of the equipment. By fixing the mounting bracket at the bottom of the base 1 and rotating the movable wheels 18, the equipment can be moved easily, allowing the entire testing device to be easily moved between different testing locations, greatly saving manpower and time costs and improving work efficiency.
[0033] In a further preferred embodiment of the present invention, the spring 10 is provided with a limiting telescopic rod 12 for limiting the extension and retraction path of the spring 10. The limiting telescopic rod 12 is composed of an outer cylinder and an inner rod. The inner rod is slidably installed inside the outer cylinder. The outer cylinder and the inner rod are respectively fixed to the connecting block 9 and the cleaning brush 11 on the side where they are close to each other.
[0034] In this embodiment, by setting the limiting telescopic rod 12 inside the spring 10, the extension and retraction path of the spring 10 is limited, so that the spring 10 can only move along the direction of the limiting telescopic rod 12 during the extension and retraction process. This avoids the spring 10 bending or deviating during extension and retraction, ensuring the stability and reliability of the spring 10. The limiting telescopic rod 12 consists of an outer cylinder and an inner rod, with the inner rod slidably installed inside the outer cylinder. This structure is simple and practical, and can effectively guide the extension and retraction movement of the spring 10. The outer cylinder and the inner rod are respectively fixed on the side of the connecting block 9 and the cleaning brush 11 that are close to each other, so that the limiting telescopic rod 12 can closely cooperate with the spring 10, the connecting block 9 and the cleaning brush 11 to work together. This ensures that the cleaning brush 11 can move smoothly and accurately when cleaning the wall, improving the cleaning effect and providing a good foundation for subsequent wall strength testing.
[0035] In a further preferred embodiment of the present invention, an elastic pad is provided on one side of the base 1 to contact the wall surface for protecting the wall surface, and the guides 14 are arranged in groups and located on both sides of the threaded cylinder 3 respectively, and the guides 14 are U-shaped.
[0036] In this embodiment, by setting an elastic pad that can contact the wall on one side of the base 1, the wall surface is protected. When the device is close to the wall for detection, the elastic pad can buffer the impact, preventing the base 1 from directly contacting the wall and preventing the wall surface from being scratched or damaged due to collision, thus ensuring the integrity of the wall surface. By setting the guide frame 14 in groups and placing them on both sides of the threaded cylinder 3, the device plays a role in balancing support and stabilizing guidance, making the force on the support cylinder 5 more uniform during the lifting process and improving the stability of the device. By designing the guide frame 14 as a U-shape, the limiting effect of the lifting path of the support cylinder 5 is further enhanced.
[0037] In summary, compared with related technologies, this device provides stable support by setting a base 1, and the limiting cylinder 2, threaded cylinder 3 and first threaded rod 4 cooperate to achieve flexible adjustment of the detection height, which is convenient for detecting walls of different heights and avoids the problem of the rebound hammer body 6 being difficult to stabilize when personnel are conducting detection at heights. The limiting cylinder 2 provides a suitable installation position for the rebound hammer body 6, and the limiting structure cooperates with the second threaded rod 7, clamping plate 19, anti-slip pad 20 and adjusting block 8 to stably clamp the rebound hammer body 6 and improve the reliability of the detection results.
