Description

Technical Field

[0001] This utility model relates to the field of building testing equipment technology, specifically a building load-bearing capacity testing device after reinforcement. Background Technology

[0002] In the field of building engineering, with the increase in the service life of existing buildings, changes in building functions, and the long-term effects of the external environment, a large number of building structures will experience varying degrees of damage, aging, or reduced load-bearing capacity, failing to meet the requirements of existing standards and safe use. Therefore, reinforcement treatment is required by means of bonding carbon fiber cloth, external steel wrapping, increasing cross-section, etc. After reinforcement, load-bearing capacity testing is a key link to verify the reinforcement effect and ensure the safe use of building structures. Its testing accuracy and reliability are particularly important.

[0003] Currently, commonly used techniques for testing the load-bearing capacity of reinforced buildings include static load testing, dynamic testing, and non-destructive testing (such as ultrasonic testing). The corresponding testing equipment is also diverse. Among them, ultrasonic non-destructive testing is widely used in the investigation of internal defects and indirect assessment of load-bearing capacity of reinforced structures due to its advantages such as convenient operation, no damage to the structure, and high testing efficiency.

[0004] In actual testing operations, ultrasonic testing instruments are usually connected and supported by a testing frame. The fixing effect of the testing frame ensures that the probe of the instrument is in close contact with the surface of the building structure, so as to ensure stable transmission of ultrasonic signals. However, the probe angle is fixed after assembly and cannot be dynamically adjusted according to the on-site conditions. When the ground at the bottom of the testing frame is uneven, the probe is prone to deviating from the ideal contact angle due to the tilt of the testing frame, resulting in a gap between the probe and the surface of the building structure. This affects the accuracy of the test data and reduces the accuracy of the entire testing device in assessing the load-bearing capacity of the reinforced structure. Utility Model Content

[0005] The purpose of this utility model is to provide a load-bearing capacity testing device for reinforced buildings, thereby solving the problems mentioned in the background section. To solve these technical problems, this utility model is achieved through the following technical solution: This utility model relates to a device for testing the load-bearing capacity of a building after reinforcement, comprising: The test frame and the main body of the ultrasonic tester are provided, and the main body of the ultrasonic tester is connected to a test probe via a connecting cable. The adjustment component includes a fixed plate embedded in one side of the detection frame. A connecting seat is fixedly provided on the side of the outer wall of the fixed plate. A locking bolt is threaded on one side of the connecting seat. A horizontal plate is fixedly provided at one end of the fixed plate. A placement seat is fixedly provided in the middle of one side of the horizontal plate, and a fixing mechanism is connected through the placement seat. A lead screw is passed through one end of one side of the horizontal plate. A knob is fixedly provided at one end of the lead screw. A connecting plate is rotatably provided at the other end of the lead screw. A mounting seat is fixedly provided at the top of the connecting plate. Several elastic blocks are symmetrically provided on both sides of the inner wall of the mounting seat, and the elastic blocks are engaged with the detection probe.

[0006] Furthermore, one end of the horizontal plate is rotatably connected to the inner wall of the testing frame.

[0007] Furthermore, the adjusting component also includes a slide rod, one end of which is fixedly mounted on one side of the connecting plate, and the outer wall of the slide rod penetrates one side of the horizontal plate.

[0008] Furthermore, the length of the slide bar is adapted to the length of the lead screw.

[0009] Furthermore, the fixing mechanism includes two fixing blocks fixed on both sides of the placement seat, each fixing block having a moving rod extending through one side, each moving rod having a spring sleeved on its outer wall, and each moving rod having a limiting clamp at one end.

[0010] Furthermore, one end of the spring is fixedly connected to one side of the fixing block, and the other end of the spring is fixedly connected to one side of the limiting clamp.

[0011] Furthermore, the fixing mechanism also includes two limiting blocks, one side of each of the two limiting blocks being fixedly connected to the other end of the two moving rods.

[0012] This utility model has the following beneficial effects: This invention, by using a horizontal plate and a connecting plate, connects and fixes the testing frame to the ultrasonic testing instrument. After placement, the locking bolts are loosened and rotated, causing the horizontal plate to rotate. This, in turn, causes the testing probe to rotate via the connecting plate until the testing probe is perpendicular to the building structure surface. Then, the locking bolts are tightened, and the rotary knob is rotated. The rotation of the knob causes the connecting plate to move via a screw until the testing probe is in close contact with the building structure surface. This method allows for dynamic adjustment of the testing probe, ensuring an ideal contact angle between the probe and the building structure surface without affecting the accuracy of the testing data. This improves the accuracy of the entire testing device in assessing the load-bearing capacity of the reinforced structure. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Please see Figures 1-4 As shown, this utility model is a bearing capacity testing device after building reinforcement, comprising: The test frame 11 and the ultrasonic tester body 12 are connected to the test probe 13 via a connecting cable. The testing frame 11 is used to connect and support the ultrasonic testing instrument to ensure stable transmission of ultrasonic signals. The main body 12 of the ultrasonic testing instrument and the testing probe 13 together constitute the ultrasonic testing instrument. The ultrasonic testing instrument adopts the HC-U91 model. It drives the probe to emit mechanical vibration waves into the building structure through the high voltage transmitting circuit of the instrument. Then, the receiving transducer receives the ultrasonic signals passing through the building structure. The mechanical vibration waves are converted into electrical signals and sent to the signal amplification and processing circuit of the instrument for signal analysis.

[0019] The adjustment component includes a fixed plate 21 embedded on one side of the detection frame 11. A connecting seat 22 is fixedly provided on the side of the outer wall of the fixed plate 21. A locking bolt 23 is threaded on one side of the connecting seat 22. A horizontal plate 24 is fixedly provided at one end of the fixed plate 21. A placement seat 241 is fixedly provided in the middle of one side of the horizontal plate 24 and a fixing mechanism is connected through the placement seat 241. A lead screw 25 is provided through one end of one side of the horizontal plate 24. A knob 26 is fixedly provided at one end of the lead screw 25. A connecting plate 27 is rotatably provided at the other end of the lead screw 25. A mounting seat 28 is fixedly provided at the top of the connecting plate 27. Several elastic blocks 281 are symmetrically provided on both sides of the inner wall of the mounting seat 28 and are engaged with the detection probe 13 through the elastic blocks 281. The fixed plate 21 is rotatably connected to the testing frame 11. The locking bolt 23 is used to limit and fix the fixed plate 21. The ultrasonic testing instrument body 12 is placed on the top of the placement seat 241. The horizontal plate 24 is threadedly engaged with the lead screw 25. The outer wall of the knob 26 is provided with anti-slip threads.

[0020] One end of the horizontal plate 24 is rotatably connected to the inner wall of the testing frame 11; The detection frame 11 assists in the rotation of the horizontal plate 24, thereby improving the overall stability of the horizontal plate 24 during rotation.

[0021] The adjusting component also includes a slide rod 29, one end of which is fixedly mounted on one side of the connecting plate 27, and the outer wall of the slide rod 29 penetrates one side of the horizontal plate 24; The slide bar 29 is used to limit the movement of the connecting plate 27, so that it moves horizontally along the direction of the lead screw 25. The slide bar 29 is in sliding engagement with the cross plate 24.

[0022] The length of slide bar 29 is adapted to the length of lead screw 25; This prevents the slide bar 29 from sliding off the horizontal plate 24.

[0023] Working principle: After fixing the main body 12 of the ultrasonic testing instrument and the testing probe 13, one side of the testing frame 11 is brought into contact with the surface of the building structure to be tested. When there are uneven surfaces on the ground where the bottom of the testing frame 11 is located, the locking bolt 23 is loosened until it is no longer in contact with the testing frame 11. Then the locking bolt 23 is rotated, which drives the fixed plate 21 to rotate through the connecting seat 22. The rotation of the fixed plate 21 drives the horizontal plate 24 to rotate, which in turn drives the testing probe 13 to rotate until the testing probe 13 is perpendicular to the surface of the building structure. Then the locking bolt 23 is tightened. Next, the rotating knob 26 is rotated. The rotation of the rotating knob 26 drives the connecting plate 27 to move towards the building structure through the lead screw 25 until the testing probe 13 is in close contact with the surface of the building structure. In this way, the testing probe 13 can be dynamically adjusted so that the probe and the surface of the building structure are at an ideal contact angle, which does not affect the accuracy of the test data, thereby improving the accuracy of the entire testing device in assessing the load-bearing capacity of the reinforced structure.

[0024] Please see Figures 1-4 As shown, this embodiment is based on the above embodiment. The fixing mechanism includes two fixing blocks 31 fixed on both sides of the placement base 241. A moving rod 32 is provided through one side of each of the two fixing blocks 31. A spring 33 is sleeved on the outer wall of each of the two moving rods 32. A limiting clamp 34 is provided at one end of each of the two moving rods 32. The movable rod 32 slides with the fixed block 31, and the limiting clamp 34 and the opposite side of the horizontal plate 24 are bonded with rubber pads to prevent the ultrasonic detector body 12 from being damaged.

[0025] One end of the spring 33 is fixedly connected to one side of the fixing block 31, and the other end of the spring 33 is fixedly connected to one side of the limiting clamp 34.

[0026] The fixing mechanism also includes two limiting blocks 35, one side of each limiting block 35 being fixedly connected to the other end of each of the two moving rods 32; The limiting block 35 is used to limit the movement of the moving rod 32.

[0027] Working principle: Before inspecting the building structure, pull the limiting clamp 34 outward to stretch the spring 33. Then, place the ultrasonic detector body 12 on the top of the placement seat 241 and slowly release the limiting clamp 34. Under the elastic action of the spring 33, the limiting clamp 34 moves in the opposite direction until it is tightly attached to the ultrasonic detector body 12. Then, move the detection probe 13 downward along the mounting seat 28 and lock it in place under the action of the elastic block 281. This split-type fixing structure not only facilitates the connection and fixing of the ultrasonic detector, but also facilitates the subsequent dynamic adjustment of the probe.
