Description
Technical Field
[0001] This utility model relates to the field of quality inspection, and in particular to a quality inspection agency for steel reinforcement in construction projects. Background Technology
[0002] In various construction projects, steel bars act like "skeletons" to support the entire building structure. Their quality directly affects the safety, durability, and stability of the project. From towering skyscrapers to infrastructure such as bridges, dams, and residences that are vital to people's livelihoods, steel bars bear enormous static and dynamic loads. Therefore, it is crucial to accurately control the quality of steel bars.
[0003] Current steel bar quality testing typically employs pull-out tests, which involve pulling out samples of steel bars in opposite directions and using strain sensors and force sensors to detect the mechanical properties of the steel bars.
[0004] On the one hand, existing steel bar quality inspection methods typically involve manually rotating gears to drive an extrusion plate to bend the steel bars. Since the steel bars are usually not fixed in a fixed manner, they are easily thrown away by the bending force, making it impossible to effectively fix multiple sets of steel bars and quickly replace steel bars of different diameters. On the other hand, existing steel bar bending points are usually at a fixed height, making it impossible to inspect different bending point locations, resulting in errors in data accuracy. Therefore, a steel bar quality inspection agency for construction projects is proposed to solve the above problems. Utility Model Content

It is used to output different torques to test the bending force of steel reinforcements of different sizes. A gear 3 is fixedly connected to the output shaft of the motor 2. The gear 3 is used to drive the torque of the motor 2 to rotate a rack 4. A rack 4 is meshed on the inner side of the outer wall of the gear 3. The rack 4 is driven to rotate by the motor 2, and then the contact plate 5 compresses the steel reinforcement to perform a radius bending motion. A contact plate 5 is fixedly connected to the top of the outer wall of the rack 4. The contact plate 5 is provided with a two-way frame for two-way bending. The bending force of the bent steel bar is tested to prevent the steel bar from springing back and swinging out. The inner wall of the top of the base 1 is provided with a sliding groove 6. The sliding groove 6 is provided with two sets, upper and lower, to engage the slider 7 and keep it sliding stably along the sliding groove 6. The slider 7 is slidably connected to the inner wall of the sliding groove 6. The slider 7 is used to engage the sliding groove 6 to keep the insertion frame 8 moving stably and to provide support for the insertion frame 8. The outer wall of the slider 7 is fixedly connected to the insertion frame 8. The top of the insertion frame 8 is provided with multiple sets of holes of different diameters for inserting steel bars of different sizes. The top of the outer wall of the base 1 is provided with a limit component. The outer wall of the ring toothed rack 4 is slidably connected to the inner wall of the base 1, and the outer wall of the insertion frame 8 is slidably connected to the top inner wall of the base 1.
[0033] Reference Figures 2-4A support frame 9 is fixedly connected to the top of the outer wall of the base 1. A collar 10 is slidably connected to the outer wall of the support frame 9. Two sets of collars 10 are provided to keep the top rod 11 at the same height and provide support for the top rod 11. The top rod 11 is fixedly connected between the two sets of collars 10. The top rod 11 is used as a bending point. The height of the top rod 11 is changed by engaging the fixing slots 16 of different heights with the fixing block 14. A fixing frame 12 is fixedly connected to the outer wall of the collar 10. The fixing frame 12 is used to keep the fixing rod 15 and the fixing block 14 moving stably and to provide space for the fixing block 14 to retract. The fixing block 14 is elastically connected to the inner wall of the fixing frame 12 by a compression spring 13. The fixing block 14 is used to engage the fixing slot 16 to fix the height of the collar 10. A fixing rod 15 is fixedly connected to the top of the outer wall of the fixing block 14. The fixing rod 15 is used for manual release from the outside. For easy manual operation, the support frame 9 has a fixing groove 16 on its outer wall. Several sets of fixing grooves 16 are provided for multiple locking and fixing blocks 14 to change the height of the top rod 11, thereby changing the height of the bending point. One end of the compression spring 13 is fixedly connected to the inner wall of the fixing frame 12, and the other end of the compression spring 13 is fixedly connected to the top of the outer wall of the fixing block 14. Through the opposing squeezing force between the compression spring 13 and the fixing frame 12, the fixing block 14 is always locked onto the inner wall of the fixing groove 16 without being affected by external force. The outer wall of the fixing rod 15 passes through and is slidably connected to the inner wall of the fixing frame 12. The bottom end of the outer wall of the fixing block 14 is slidably connected to the inner wall of the collar 10, the top end of the outer wall of the fixing block 14 is slidably connected to the inner wall of the fixing frame 12, and the bottom end of the outer wall of the fixing block 14 is locked onto the inner wall of the fixing groove 16.
[0034] Reference Figures 4-5 The limiting component includes a limiting frame 17, which is used to maintain the stable movement of the limiting block 19 and the limiting rod 20. The bottom of the outer wall of the limiting frame 17 is fixedly connected to the top of the outer wall of the base 1. The inner wall of the limiting frame 17 is elastically connected to the limiting block 19 through a limiting spring 18. The limiting block 19 is used to engage with the limiting groove 21 to fix the insertion frame 8. The top of the outer wall of the limiting block 19 is fixedly connected to the limiting rod 20, which is used for external manual release of the limiting position for easy manual operation. The front of the outer wall of the insertion frame 8 has a limiting groove 21. There are four sets of limiting grooves 21, and the number can be changed according to actual needs to use multiple locking limiting blocks. 19. Fix the insertion frame 8, thereby driving the holes of different sizes to align and bend. One end of the limiting spring 18 is fixedly connected to the top of the inner wall of the limiting frame 17, and the other end of the limiting spring 18 is fixedly connected to the top of the outer wall of the limiting block 19. Through the opposing extrusion force between the limiting spring 18 and the limiting frame 17, the limiting block 19 is always locked on the inner wall of the limiting groove 21 without being affected by external force. The outer wall of the limiting rod 20 passes through and is slidably connected to the inner wall of the limiting frame 17. The outer wall of the limiting block 19 is slidably connected to the inner wall of the limiting frame 17, and the bottom end of the outer wall of the limiting block 19 is locked on the inner wall of the limiting groove 21.
[0035] Working principle: When testing steel bars of different sizes, the limiting rod 20 is manually pulled to move the limiting block 19 out of the limiting groove 21 to release the limit. Then, the insertion frame 8 is manually moved to align the hole for the steel bar of the required size with the bending position. Then, the limiting rod 20 is released and the limiting spring 18 simultaneously pushes the limiting block 19 back into the corresponding limiting groove 21 for locking. Then, four sets of steel bars are inserted into the holes of the insertion frame 8 along the inner side of the contact plate 5. Then, the motor 2 is turned on, and the motor 2 drives the gear 3 to rotate. The gear 3 drives the rack 4 to rotate, and the rack 4 drives the contact plate 5 to contact and compress the steel bars, thereby performing bending force testing on the steel bars. This achieves bending force testing on multiple sets of steel bars.
[0036] When inspecting different bending points of reinforcing bars, the fixing rod 15 is manually pulled to move the fixing block 14 away from the fixing groove 16 to release the limit. Then, the lower collar 10 is manually slid down to move the top rod 11 to the height of the bending point to be inspected. Then, the fixing rod 15 is pushed inward to move the fixing block 14 into the corresponding fixing groove 16, so as to realize the manual and quick adjustment of the bending point height and improve the rigor of the inspection.
