[0002] Steel bars play an important role in enhancing the strength of concrete structures and resisting tensile forces. Due to the influence of many factors such as environmental factors, construction quality, and material quality, the quality of steel bars may be damaged to a certain extent. In order to ensure the structural safety and durability of buildings, the strength of steel bars needs to be tested.

[0003] Existing patent publication number CN221405174U, titled "A Construction Rebar Strength Testing Mechanism," proposes that this device, through the coordinated use of a lower clamping block, lead screw, screw, upper clamping block, driven gear, motor, and driving gear, can securely support rebar of varying thicknesses, preventing them from shifting or sliding during testing. By combining the use of a special-shaped slot, gear, first bending head, second bending head, rack, and connecting block, the device can bend rebar at various angles according to testing requirements, facilitating observation of the strength and toughness of the rebar under various bending conditions, thereby obtaining more accurate test data.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-Figure 5The shown type of building steel bar strength detection includes an operating table 1, a rotating component is provided on the operating table 1, and the rotating component is driven to rotate by a power component. The rotating component includes a fixed shaft 2, the fixed shaft 2 is fixedly provided on the top of the operating table 1, and two connecting shafts are rotatably provided at the outer ring of the fixed shaft 2. A turntable 3 and a first gear 4 are fixedly provided at the outer ring of the two connecting shafts. The turntable 3 and the first gear 4 are fixedly connected and formed as one piece. A plurality of through holes 5 evenly distributed in a ring shape are fixedly provided on the upper turntable 3 and the first gear 4, and a number of blind holes 6 with the same number as the through holes 5 are fixedly provided on the lower turntable 3, and the positions of the through holes 5 and the blind holes 6 correspond one to one. A bending rod 7 is slidably provided between a corresponding group of through holes 5 and the blind holes 6.

[0026] Specifically, the two steel bar test samples are respectively limitedly installed on the two turntables 3. Through the installation of the two connecting shafts, after the power assembly is running, the two turntables 3 can be driven to rotate synchronously. After driving the bending rod 7 to rotate, with the cooperation of the fixed shaft 2, the bending rod 7 bends one end of the steel bar test sample to a certain angle, thereby performing bending strength testing on the two steel bar test samples at the same time. After the bending is completed, the two steel bar test samples are removed and observed to see if cracks or deformation occur, so that the flexibility and cold bending properties of the steel bars can be evaluated, and relevant markings can be made.

[0027] In summary, the utility model can perform strength testing on two steel bar test samples at a time, solving the problem that existing building steel bar strength testing equipment can only perform strength testing on one steel bar sample at a time, resulting in low testing efficiency.

[0028] In order to stably bend the steel bar inspection sample, a limit assembly is provided on the operating table 1, which includes a support rod 12, which is fixedly arranged on the top of the operating table 1, and two limit rods 13 are rotatably provided on the side of the support rod 12. The lower surface of the limit rod 13 and the upper surface of the turntable 3 are movably fitted. A support seat 14 is also fixedly provided on the top of the operating table 1, and two screw rods 15 are rotatably provided on the internal thread of the support seat 14. The screw rod 15 and the limit rod 13 are rotatably connected at one end away from the support rod 12, and the second gear 16 is fixedly connected to the end of the screw rod 15 away from the limit rod 13. The two second gears 16 are meshed with each other, and a rotating rod 17 is fixedly provided on the side of the upper second gear 16.

[0029] Specifically, the steel bar inspection sample is placed between the limit rod 13 and the fixed shaft 2, and is placed close to the limit rod 13. A certain length should be left at the end of the steel bar inspection sample that contacts the bending rod 7 to avoid the problem of the bending rod 7 coming off the pin after bending. At this time, the rotating rod 17 is rotated to drive the two second gears 16 to rotate relative to each other, and the two screw rods 15 are driven to rotate in the support seat 14, thereby pushing the limit rod 13 to rotate, so that the steel bar inspection sample is stuck between the limit rod 13 and the fixed shaft 2, so that the steel bar inspection sample is firmly limited and fixed, which is convenient for improving the bending stability of the steel bar inspection sample.

[0030] In addition, because the threads on the two screw rods 15 have opposite directions, the displacement of the screw rods 15 can be synchronized, thereby simultaneously limiting and fixing the two steel bar test samples, thereby improving the convenience of installation and disassembly of the steel bar test samples.

[0031] Furthermore, the power assembly includes a machine box 8, a movable groove is fixedly provided inside the machine box 8, a hydraulic cylinder 9 is fixedly provided at the end of the movable groove, the telescopic end of the hydraulic cylinder 9 is fixedly connected to a movable rod 10 adapted to the movable groove, and two racks 11 are fixedly provided on one side of the movable rod 10 that is movably extended out of the movable groove, and the two racks 11 are respectively engaged with the two first gears 4.

[0032] Specifically, after the steel bar inspection sample is installed, the parameters are adjusted through the external controller, and the hydraulic cylinder 9 is started to drive the movable rod 10 and the two racks 11 to slide inside the movable groove, thereby synchronously driving the two first gears 4 to rotate a certain angle, and then driving the bending rod 7 to rotate to bend one end of the steel bar inspection sample. After bending the specified angle, the hydraulic cylinder 9 is stopped, and the rotating rod 17 is rotated in the opposite direction to loosen the bent steel bar inspection sample, so that it is easy to remove and observe whether the two steel bar inspection samples are cracked or deformed.

[0033] In order to place the steel bar inspection samples to prevent them from rolling or being placed randomly, a placement component is provided on the operating table 1, and the placement component includes a placement plate 19. The placement plate 19 is fixedly provided on the top of the operating table 1. The top of the placement plate 19 is fixedly provided with a plurality of slots with a vertical cross-section of "V" shape and evenly arranged. A placement slot is fixedly provided at the bottom of the operating table 1, and no less than two evenly arranged hanging rods 20 are fixedly provided at the end of the placement slot, and a plurality of evenly arranged limiting rings are fixedly provided at the outer ring of the hanging rod 20.

[0034] The steel bar test samples to be tested are placed on the placement plate 19, and the multiple steel bar test samples are limited by the "V"-shaped and evenly arranged slots to prevent them from rolling. The steel bar test samples that have completed the experiment and are well marked are placed on the hanging rod 20. The limiting ring makes it easy to separate and place multiple steel bar test samples, so that the corresponding samples can be found quickly.

[0035] Furthermore, a protective cover 18 is provided on the machine box 8 by rotating through a hinge. During testing, the protective cover 18 needs to be lowered to protect the experimenter and avoid accidents.

[0036] It should be noted that after the steel bar inspection sample is installed, the bending rod 7 is placed in a suitable position, the hydraulic cylinder 9 is started, and after the bending rod 7 fits the steel bar inspection sample, the hydraulic cylinder 9 is stopped, and then the parameters of the external controller are adjusted.
