[0002] The main purpose of anchor bolt inspection is to verify the bond strength and anchoring effect between the anchor bolt and the surrounding structural materials, ensure that the anchor bolt construction meets design requirements, and assess its long-term safety and stability. Specifically, the objectives of anchor bolt inspection include: verifying the load-bearing capacity of the anchor bolt, assessing the quality of anchor bolt construction and long-term safety, and optimizing design and construction processes.
[0003] A search revealed that application document CN211665813U discloses a locking anchor bolt detection support pad and detection device. This locking anchor bolt detection support pad and detection device effectively solves the problems of the old-style pad requiring a large number of pads for detection, gaps between each steel plate wasting jack extension during tensioning, and the cumbersome use of the old-style pads. It also reduces errors, decreases the workload during detection, and is convenient to use.
[0004] However, there are still some defects and shortcomings that need to be optimized. The specific defects and shortcomings are as follows: The top surface of the support pad in the locking anchor bolt detection support pad and detection device has no clamp design for the jack, which makes it easy for the bottom surface of the jack and the support pad to be misaligned when installed on an inclined surface, which is not conducive to installation and detection. Therefore, it is necessary to design an anchor bolt detection support pad and detection device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide an anchor bolt detection support pad and detection device. This anchor bolt detection support pad and detection device optimizes the structure of the support pad in the existing locking anchor bolt detection support pad and detection device. By using the design of the adjustable jack clamp assembly, the bottom end of the jack can be clamped, which effectively prevents misalignment between the bottom surface of the jack and the support pad when installed on an inclined surface, which is conducive to installation and detection, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An anchor bolt detection support pad includes an anchor bolt detection support pad body, which is composed of a main body and an adjustable jack clamp assembly. The main body includes a lower support plate and an upper support plate arranged in parallel. A support cylinder is fixedly installed between the lower support plate and the upper support plate. A jack limiting ring cylinder is fixedly installed on the top surface of the upper support plate. The adjustable jack clamp assembly includes several sets of jack clamp bodies arranged in a ring. The several sets of jack clamp bodies arranged in a ring are movably installed inside the jack limiting ring cylinder by corresponding limiting telescopic rods.
[0008] Preferably, the inner wall and outer surface of any one of the several groups of jack clamp bodies arranged in a ring are provided with an arc-shaped design.

[0010] Preferably, the outer surface of the jack limiting ring cylinder is provided with a matching telescopic rod through hole near each set of limiting telescopic rods, and the telescopic end of each set of limiting telescopic rods passes through the interior of the corresponding telescopic rod through hole and is fixedly connected to the jack clamp body.
[0011] Preferably, the lower support plate and the upper support plate are provided with through holes equal to the inner diameter of the support cylinder, and an upper support block and a lower support block are fixedly installed on the outer surface of the support cylinder between the lower support plate and the upper support plate, which are distributed vertically. The upper support block and the lower support block are both triangularly arranged.
[0012] This utility model also provides a detection device that uses the anchor bolt detection support pad as described above, and further includes an anchor bolt jack, an anchor plate, an anchor, and an anchor bolt. The bottom end of the anchor bolt jack is fixedly installed inside the jack limiting ring cylinder through an adjustable jack clamp assembly. The top end of the anchor bolt jack is fixedly installed with an anchor through the anchor plate. The anchor bolt penetrates the interior of the anchor bolt detection support pad body, the anchor bolt jack, the anchor plate, and the anchor, and the top end of the anchor bolt extends to the end of the anchor away from the anchor plate. Hydraulic interfaces are fixedly installed on the outer surface of the anchor bolt jack near both the top and bottom ends.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Example:
[0023] This utility model provides an anchor bolt detection support pad and detection device. The anchor bolt detection support pad and detection device optimize the structure of the support pad in the existing locking anchor bolt detection support pad and detection device. The adjustable jack clamp assembly can clamp the bottom end of the jack, effectively preventing misalignment between the bottom surface of the jack and the support pad when installed on an inclined surface. This facilitates installation and detection, thus solving the problems mentioned in the background art.
[0024] Please see Figures 1-5 This utility model provides a technical solution:
[0025] An anchor bolt detection support pad includes an anchor bolt detection support pad body 1.
[0026] The anchor bolt detection support pad body 1 is composed of a main body 11 and an adjustable jack clamp assembly 12. The main body 11 includes a lower support plate 111 and an upper support plate 112 arranged in parallel. A support cylinder 113 is fixedly installed between the lower support plate 111 and the upper support plate 112. Through holes with the same inner diameter as the support cylinder 113 are opened through the lower support plate 111 and the upper support plate 112. A jack limiting ring cylinder 114 is fixedly installed on the top surface of the upper support plate 112. An upper support block 115 and a lower support block 116 are fixedly installed between the lower support plate 111 and the upper support plate 112 near the outer surface of the support cylinder 113. The upper support block 115 and the lower support block 116 are both triangularly arranged. The adjustable jack clamp assembly 12 includes several sets of jack clamp bodies 121 arranged in a ring. 21 The corresponding limiting telescopic rod 122 is movably installed inside the jack limiting ring cylinder 114. The inner wall and outer surface of any one of the several groups of jack clamp bodies 121 arranged in a ring are all provided with an arc design. When the bottom end of the anchor jack 2 is placed on the inner bottom surface of the jack limiting ring cylinder 114 and the limiting telescopic rod 122 is activated, the jack clamp body 121 begins to move closer to the anchor jack 2 until it is clamped. This effectively prevents misalignment between the bottom surface of the jack and the support pad when installed on an inclined surface, which is conducive to installation and inspection. At the same time, the design of several groups of jack clamp bodies 121 arranged in a ring and the corresponding limiting telescopic rod 122 not only provides a greater and more stable clamping force on the anchor jack 2, but also is applicable to anchor jacks 2 of different sizes, making it more practical. At the same time, the automatic adjustment of clamping is convenient and quick.
[0027] Furthermore, in this embodiment, please refer to Figure 2 and Figure 4The outer surface of the jack limiting ring cylinder 114 is provided with a matching telescopic rod through hole 1141 near each set of limiting telescopic rods 122. The telescopic end of each set of limiting telescopic rods 122 passes through the interior of the corresponding telescopic rod through hole 1141 and is fixedly connected to the jack clamp body 121. The design of the telescopic rod through hole 1141 facilitates the connection between the limiting telescopic rod 122 and the jack clamp body 121.
[0028] Furthermore, in this embodiment, please refer to Figure 4 and Figure 5 The bottom of any one of the several groups of jack clamp bodies 121 arranged in a ring is fixedly installed with an adjustment limit slider 123. The top surface of the upper support plate 112 is provided with an adjustment limit groove 1121 corresponding to the several groups of jack clamp bodies 121 arranged in a ring. The adjustment limit groove 1121 and the adjustment limit slider 123 are slidably connected. The design of the adjustment limit groove 1121 and the adjustment limit slider 123 can make the automatic adjustment and clamping process stable, reliable and smooth, and prevent shaking.
[0029] This embodiment also provides a detection device that utilizes the aforementioned anchor bolt detection support pad, and further includes an anchor bolt jack 2, an anchor plate 3, an anchor 4, and an anchor bolt 5. The bottom end of the anchor bolt jack 2 is fixedly installed inside the jack limiting ring cylinder 114 via an adjustable jack clamp assembly 12. The top end of the anchor bolt jack 2 is fixedly installed with the anchor 4 via the anchor plate 3. The anchor bolt 5 penetrates the interior of the anchor bolt detection support pad body 1, the anchor bolt jack 2, the anchor plate 3, and the anchor 4, with the top end of the anchor bolt 5 extending to the end of the anchor 4 away from the anchor plate 3. Hydraulic interfaces 21 are fixedly installed on the outer surface of the anchor bolt jack 2 near both the top and bottom ends. After the anchor bolt 5 is installed, the anchor bolt detection support pad body 1 is installed first, followed by the installation of the anchor bolt jack 2, the anchor plate 3, and the anchor 4 in sequence, and connected to an external hydraulic oil system via the hydraulic interfaces 21. A continuous connection is made, and the tension on the anchor 5 is gradually increased using equipment such as anchor jack 2 until the anchor 5 shows significant displacement or reaches the maximum tension required by the design. During this process, the anchor jack 2 works according to Pascal's law, that is, in a closed system, applying a certain pressure to one piston will produce the same pressure increment on another piston, thereby generating the required tension. While applying the load, the displacement of the anchor and the applied tension value are recorded in real time to plot the load-displacement curve. By analyzing the load-displacement curve, it is determined whether the pull-out resistance of the anchor meets the design requirements. If necessary, further analysis and adjustment can be carried out. This testing method is not only suitable for evaluating the bearing capacity of the anchor, but can also comprehensively test the quality and performance of the anchor through various types of tests such as basic tests, acceptance tests and creep tests.
[0030] In this embodiment of the anchor bolt detection support pad and detection device, after the anchor bolt 5 is installed, the main body 1 of the anchor bolt detection support pad is installed first, followed by the installation of the anchor bolt jack 2, anchor plate 3, and anchor 4 in sequence. When installing the anchor bolt jack 2, the bottom end of the anchor bolt jack 2 is placed inside the bottom surface of the jack limiting ring cylinder 114, and the limiting telescopic rod 122 is activated. Simultaneously, under its action, the jack clamp body 121 begins to move closer to the anchor bolt jack 2 until it is clamped. Then, it is connected to the external hydraulic oil system through the hydraulic interface 21. At the same time, the tension on the anchor bolt 5 is gradually increased through the anchor bolt jack 2 and other equipment until the anchor bolt 5 shows significant displacement or reaches the maximum tension required by the design. During this process, the anchor bolt jack 2 operates according to Pascal's law, that is, in a closed system, applying a certain pressure to one piston will cause a reaction in another piston. The same pressure increment is generated on each piston, thereby generating the required tension. While applying the load, the displacement of the anchor rod and the applied tension value are recorded in real time to plot the load-displacement curve. By analyzing the load-displacement curve, it is determined whether the pull-out resistance of the anchor rod meets the design requirements. If necessary, further analysis and adjustment can be carried out. The overall structure of the existing locking anchor rod detection support pad and the support pad in the detection device is optimized. The design of the adjustable jack clamp assembly 12 can clamp the bottom end of the jack, effectively preventing misalignment between the bottom surface of the jack and the support pad when installed on an inclined surface, which is conducive to installation and detection.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
