Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable rebar sleeve connection quality detection device. Background Technology

[0002] In infrastructure construction fields such as building engineering, bridge construction, and rail transit, reinforcing bars are core load-bearing components, and the quality of their connections directly determines the stability, load-bearing capacity, and service life of the entire structure. Reinforcing bar sleeve connections, with their advantages of high joint strength, convenient construction, and strong adaptability, have gradually replaced traditional tying and welding connections, becoming one of the mainstream technologies for reinforcing bar connections. This connection method involves inserting the ends of two reinforcing bars into a sleeve and fixing them through processes such as extrusion, threaded engagement, or grouting. Whether the connection quality meets the standards directly affects the safety performance of the engineering structure; therefore, accurate testing of the quality of reinforcing bar sleeve connections is a crucial link in the quality control of engineering construction.

[0003] Currently, the core indicators for testing the quality of rebar sleeve connections mainly include the fit clearance between the sleeve and the rebar, the coaxiality after connection, the dimensional accuracy of the sleeve itself, and the correlation of the mechanical properties of the joint. Among these, accurate measurement of geometric parameters is the basic prerequisite for quality assessment. Most existing rebar sleeve connection quality testing devices are based on the design of sleeves of specific specifications. The core components such as the clamping range of the measuring mechanism, the spacing of the measuring probes, and the positioning reference are all fixed structures, which can only be adapted to a single or very small range of rebar sleeve specifications.

[0004] However, in actual engineering construction, the specifications of rebar sleeves need to be flexibly adjusted according to the rebar diameter, stress level, and other requirements. Common sleeve inner diameter specifications cover multiple ranges from 12mm to 40mm, and parameters such as sleeve length and wall thickness also vary significantly. Faced with such diverse specification requirements, existing fixed-specification testing devices have revealed obvious limitations: on the one hand, construction units need to equip themselves with multiple sets of testing devices corresponding to different sleeve specifications, which not only significantly increases equipment procurement costs and storage space costs, but also increases the workload of equipment maintenance and calibration; on the other hand, during on-site testing operations, testing personnel need to frequently change different testing devices to adapt to the sleeves to be tested. During the replacement process, equipment debugging and benchmark calibration need to be re-performed, which not only prolongs the testing cycle and reduces construction efficiency, but may also introduce human error due to frequent debugging, affecting the accuracy and reliability of the test results.

[0005] To address this issue, an adjustable rebar sleeve connection quality testing device is proposed to solve the problems existing in the current technology. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems by providing an adjustable rebar sleeve connection quality inspection device. This utility model achieves lateral movement adjustment of the two measuring rulers by setting a centering adjustment component between the inspection rod and the base rod, thus overcoming the technical shortcomings of existing inspection devices that have fixed measurement ranges and can only adapt to a single or very small range of rebar sleeve specifications. With the adjustment function of the centering adjustment component, the distance between the two measuring rulers can be flexibly adjusted according to different specifications such as the inner diameter and length of the rebar sleeve to be inspected. This allows the device to adapt to the inspection needs of various rebar sleeves from smaller to larger specifications, eliminating the need for multiple inspection devices for different sleeve specifications and significantly reducing equipment procurement and maintenance costs. To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: According to one aspect of the present invention, an adjustable rebar sleeve connection quality inspection device is provided, comprising a base rod, a detection rod provided at one end of the base rod, and two ribs symmetrically provided at the connection between the base rod and the detection rod, a detection groove provided in the middle section of the detection rod, two measuring rulers symmetrically provided on the detection rod, and a centering adjustment component provided between the detection rod and the base rod for adjusting the lateral movement of the two measuring rulers.

[0007] Preferably, the centering adjustment assembly includes two symmetrically arranged adjustment slots on the detection rod, each adjustment slot having an adjustment block, and each adjustment block extending upward beyond the adjustment slot. Each measuring scale is disposed on the top of the corresponding adjustment block. A sliding groove is provided on the base rod, and a slider is provided within the sliding groove. Two connecting posts symmetrically arranged at the bottom of the slider are provided, and each adjustment block has a connecting post 2 at its bottom. A connecting rod is hinged between each connecting post 1 and the connecting post 2 on the same side. A support rod is provided at the top of the slider, extending beyond the sliding groove, and a driving block is provided at the top of the support rod.

[0008] Preferably, the slider has a groove, the support rod is disposed in the groove and cooperates with the groove, the lower end of the drive block has a locking block, and the shape of the locking block cooperates with the upper edge of the slide groove, and the locking block is made of rubber.

[0009] Preferably, each of the measuring rulers can be detachably mounted on the corresponding adjusting block.

[0010] Preferably, the top of the drive block is provided with an anti-slip pad.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The adjustable rebar sleeve connection quality inspection device of this utility model realizes the lateral movement adjustment of the two measuring rulers by setting a centering adjustment component between the detection rod and the base rod. This solves the technical defects of existing detection devices that have a fixed measurement range and can only adapt to a single or very small range of rebar sleeve specifications. With the adjustment function of the centering adjustment component, the distance between the two measuring rulers can be flexibly adjusted according to different specification parameters such as the inner diameter and length of the rebar sleeve to be inspected. This allows the device to adapt to the inspection needs of various rebar sleeves from smaller to larger specifications, eliminating the need to equip multiple sets of inspection devices for different specifications of sleeves, and greatly reducing equipment procurement and maintenance costs.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0014] Please see Figures 1 to 4 This utility model provides an adjustable rebar sleeve connection quality detection device, the technical solution of which is as follows: It includes a base rod 1, a detection rod 2 is provided on one end of the base rod 1, and two ribs 3 are symmetrically provided at the connection between the base rod 1 and the detection rod 2. A detection groove 4 is provided in the middle section of the detection rod 2. Two measuring rulers 5 are symmetrically provided on the detection rod 2, and a centering adjustment component is provided between the detection rod 2 and the base rod 1 for adjusting the lateral movement of the two measuring rulers 5.

[0015] By setting a centering adjustment component between the detection rod 2 and the base rod 1, the lateral movement adjustment of the two measuring rulers 5 is realized, which solves the technical defects of the existing detection device that has a fixed measurement range and can only adapt to a single or very small range of rebar sleeve specifications. With the adjustment function of the centering adjustment component, the distance between the two measuring rulers 5 can be flexibly adjusted according to different specification parameters such as the inner diameter and length of the rebar sleeve to be detected. This allows the device to adapt to the detection needs of various rebar sleeves from smaller to larger specifications, eliminating the need to equip multiple detection devices for different specifications of sleeves. This significantly reduces equipment procurement and maintenance costs, while also reducing the burden of equipment storage and transportation. It is especially suitable for scenarios where specifications are frequently changed during on-site construction.

[0016] The centering adjustment assembly includes two symmetrically arranged adjustment slots 6 on the detection rod 2. Each adjustment slot 6 is provided with an adjustment block 7, and each adjustment block 7 extends upward beyond the adjustment slot 6. Each measuring scale 5 is set on the top of the corresponding adjustment block 7. A sliding groove 8 is provided on the base rod 1, and a slider 9 is provided in the sliding groove 8. Two connecting posts 10 are symmetrically arranged at the bottom of the slider 9. Each adjustment block 7 is provided with a connecting post 21 at the bottom. A connecting rod 12 is hinged between each connecting post 10 and the connecting post 21 on the same side. A support rod 13 is provided at the top of the slider 9. The support rod 13 extends beyond the sliding groove 8, and a driving block 14 is provided at the top of the support rod 13.

[0017] The centering adjustment component uses a hinged linkage structure between the slider 9, connecting rod 12, and two adjusting blocks 7 on both sides. When the drive rod 13 moves the slider 9 along the slide groove 8, the slider 9 pulls the connecting rods 12 on both sides simultaneously through the connecting column 10, thereby driving the two adjusting blocks 7 to move laterally in opposite directions along the adjustment groove 6, realizing the synchronous approach or distance of the two measuring rulers 5. This linkage design ensures that the measuring rulers 5 are always symmetrically distributed with the detection groove 4 as the center, eliminating the need to adjust one side of the measuring ruler 5 separately. This completely solves the centering deviation problem that easily occurs when manually adjusting the measuring mechanisms on both sides of the existing device, effectively ensuring the consistency of the measurement benchmark and significantly improving the detection accuracy of key indicators such as the fit clearance and coaxiality of the rebar sleeve.

[0018] By simply moving the support rod 13 and slider 9 via the drive block 14, the distance between the two adjustment blocks 7 and measuring ruler 5 can be synchronously controlled via the connecting rod 12. The adjustment process requires no complicated tools and the operation steps are simple and intuitive. Compared with the prior art, this application realizes one-click synchronous adjustment, which greatly shortens the equipment debugging time when testing different specifications of steel bar sleeves, reduces the operation difficulty for testing personnel, and significantly improves the efficiency of on-site testing. It is especially suitable for scenarios where sleeve specifications are frequently changed during construction.

[0019] The slider 9 has a groove 15 inside, the support rod 13 is set in the groove 15 and the support rod 13 cooperates with the groove 15, the lower end of the drive block 14 has a locking block 16, and the shape of the locking block 16 cooperates with the upper edge of the slide groove 8. The locking block 16 is made of rubber.

[0020] During adjustment, lifting the drive block 14 allows for sliding. When fixing, pressing down the drive block 14 engages the locking block 16 with the upper edge of the slide groove 8. The locking block 16 at the lower end of the drive block 14 precisely matches the upper edge of the slide groove 8. After pressing down the drive block 14, the locking block 16 achieves rigid positioning through mechanical engagement with the edge of the slide groove 8, effectively limiting the lateral displacement of the slider 9, adjusting block 7, and measuring ruler 5. Simultaneously, the locking block 16, made of rubber, allows for a tight fit between the locking block 16 and the edge of the slide groove 8, increasing contact friction and further preventing loosening or positional shift due to vibration or external force during testing. This dual locking effect ensures that the spacing of the measuring ruler 5 remains stable throughout the testing process, avoiding testing errors caused by positional shifts and significantly improving the reliability of the testing results.

[0021] Each of the measuring rulers 5 can be detachably installed on the corresponding adjusting block 7; the detachable design allows the device to flexibly replace different types, accuracies, or measurement ranges of measuring rulers 5 according to the needs of different testing scenarios and testing indicators; without the need to purchase multiple sets of special testing devices, it can achieve accurate testing of multiple dimensions of indicators such as the fit clearance of steel bar sleeves, connection length, and coaxiality deviation, which greatly improves the functional expandability and scenario adaptability of the device and meets the usage needs of different specifications and testing standards in construction engineering.

[0022] The top of the drive block 14 is provided with an anti-slip pad 17. The anti-slip pad 17 increases the surface roughness of the top of the drive block 14, which effectively increases the frictional resistance between the hand and the drive block 14. Even if the hands of the inspector are covered with dust, oil, cement slurry and other impurities from the construction site, they can still hold the drive block 14 firmly to lift or press, avoiding operational errors caused by slipping.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
