Description

Technical Field

[0001] This utility model relates to the field of concrete rebound hammers, specifically a segmented portable concrete rebound hammer operating bracket. Background Technology

[0002] A concrete rebound hammer is a portable instrument used for non-destructive testing of the surface hardness of concrete structures. Its working principle is based on the rebound method: a spring-driven hammer strikes the concrete surface, the rebound distance (rebound value) is measured, and a pre-calibrated curve is used to convert the rebound value into an estimated value of the concrete's compressive strength. This instrument is easy to operate and provides rapid testing, making it suitable for on-site quality acceptance and evaluation of building structures, bridges, tunnels, and other engineering projects. Its advantage lies in its non-destructive nature, avoiding damage to the structure caused by core sampling. However, the test results are affected by factors such as carbonation depth and surface smoothness, and usually need to be corrected by combining core drilling or ultrasonic methods to improve the accuracy of the strength estimation.

[0003] In construction engineering, strength testing of concrete structures is crucial, and rebound hammers are one of the commonly used non-destructive testing devices, especially when conducting rebound tests on the concrete strength of ceiling slabs at high floors. However, existing methods have many drawbacks. Traditional methods typically require setting up a mobile operating platform or using an A-frame ladder, with operators standing at a height and manually adjusting the rebound hammer's position. This poses significant safety risks for operators working at heights. Furthermore, setting up operating platforms or using ladders is time-consuming, labor-intensive, and inconvenient to move, greatly reducing testing efficiency. While some auxiliary devices exist on the market, most are complex in structure, inconvenient to carry and assemble, and cannot meet the flexible and ever-changing testing needs of construction sites. Therefore, there is an urgent need for a portable, retractable rebound hammer auxiliary device that can solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a segmented portable concrete rebound hammer operating bracket, including an extension rod, the top end of which is threadedly connected to a bracket structure, the rebound hammer being installed inside the bracket structure, and the extension rod and the bracket structure being a separate and detachable structure.

[0005] Preferably, the extension rod includes a rod body, and a threaded joint is fixedly connected to the top end of the rod body.

[0006] Preferably, the support structure includes a fixed rod, a placement frame is fixedly connected to one side of the fixed rod, a through limiting groove is opened on one side of the inner wall of the placement frame, and several sets of buffer rubber strips of different sizes are fixed inside the placement frame.

[0007] Preferably, the fixing rod is hollow, and the inner wall of the bottom end of the fixing rod has a threaded groove corresponding to the threaded joint.

[0008] Preferably, the rebound spring includes a rebound spring body, and a display screen is fixedly connected to one side of the rebound spring body.

[0009] Preferably, the limiting groove of the bracket structure corresponds to the display screen, and the combination of the rebound device and the bracket structure is realized by inserting the display screen into the limiting groove.

[0010] Preferably, the main body of the rod, the fixing rod, and the placement frame are all made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model proposes a segmented portable concrete rebound hammer operating support. This device utilizes a specially designed clamp to ensure that the rebound hammer's axis remains perpendicular to the top slab testing surface during the testing process, reducing data errors caused by angular deviations and significantly improving the accuracy of the test results. Simultaneously, operators no longer need to stand on mobile operating platforms or A-frame ladders in high-risk positions to hold the rebound hammer; they can simply operate this auxiliary device from the ground to complete the testing of high-altitude top slabs, effectively reducing the safety risks associated with working at heights. The separate design of the extension rod and support structure makes the assembly and disassembly of the device simple and quick, and can be completed in a short time. Furthermore, the uprights are made of lightweight materials, making them easy to carry and adaptable to the rapid transfer needs of different construction sites, greatly improving the efficiency of the testing work.

[0019] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0020] Please see Figures 1 to 4 This utility model provides a segmented portable concrete rebound hammer operating bracket, including an extension rod 1, a bracket structure 2 threadedly connected to the top of the extension rod 1, a rebound hammer 3 installed inside the bracket structure 2, and the extension rod 1 and the bracket structure 2 are separate and detachable structures.

[0021] This device utilizes a specially designed clamp to ensure that the rebound hammer 3 always maintains its axis perpendicular to the top plate detection surface during the testing process, reducing detection data errors caused by angular deviations and greatly improving the accuracy of the test results. At the same time, operators no longer need to stand on mobile operating platforms or A-frame ladders or other high-risk positions to hold the rebound hammer 3 for testing. They can simply operate this auxiliary device from the ground to complete the detection work on the top plate at high altitudes, effectively reducing the safety risks associated with working at heights. The separate design of the extension rod 1 and the support structure 2 makes the assembly and disassembly of the device simple and quick, and can be completed in a short time. Moreover, the upright is made of lightweight materials, making it easy to carry and adaptable to the rapid transfer needs of different construction sites, greatly improving the efficiency of the testing work.

[0022] The extension rod 1 includes a rod body 11, and a threaded joint 12 is fixedly connected to the top end of the rod body 11;

[0023] The support structure 2 includes a fixed rod 21, a placement frame 22 is fixedly connected to one side of the fixed rod 21, a through limiting groove 23 is opened on one side of the inner wall of the placement frame 22, and several sets of buffer rubber strips 24 of different sizes are fixed inside the placement frame 22.

[0024] The fixing rod 21 is hollow, and the inner wall of the bottom end of the fixing rod 21 has a threaded groove corresponding to the threaded joint 12;

[0025] When assembling, the extension rod 1 is screwed into the corresponding threaded groove on the inner wall of the bottom end of the fixed rod 21 using the threaded connector 12 to achieve the effect of extension. The use of the buffer rubber strip 24 can ensure that the rebound device 3 will not shake or deform when installed in the bracket structure 2, thus improving the stability of the installation.

[0026] The rebounder 3 includes a rebounder body 31, and a display screen 32 is fixedly connected to one side of the rebounder body 31;

[0027] The limiting groove 23 of the bracket structure 2 corresponds to the display screen 32. The combination of the rebound device 3 and the bracket structure 2 is achieved by inserting the display screen 32 into the limiting groove 23.

[0028] When installing the rebound hammer 3, the internal contour of the placement frame 22 is adapted to the rebound hammer body 31, and the display screen 32 is locked in the limiting groove 23, which can ensure that the rebound hammer 3 remains stable in the support structure 2, thus improving the accuracy of the test results.

[0029] The main body 11, the fixing rod 21, and the placement frame 22 are all made of stainless steel.

[0030] The stainless steel material provides excellent support and structural strength, while also being lightweight. When in use, the operator holds the main body 11 of the rod and lifts the rebound device 3 to the top of the wall for use. The overall lightweight design ensures comfortable and easy grip, which is beneficial for long-term use.
