Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure testing technology, and in particular to a bending testing device for building steel structures. Background Technology
[0002] Bending testing devices for building steel structures are mainly used to evaluate the mechanical properties and deformation behavior of steel structure materials under bending loads. These devices have wide applications in steel structure manufacturing, building engineering quality inspection, and materials science research.
[0003] In the process of bending testing steel structures, to ensure the accuracy and comprehensiveness of the test results, it is usually necessary to conduct detailed bending tests at multiple points on the steel structure. This is not only because the steel structure may be subjected to different mechanical forces and deformations at different locations, but also because multi-point testing can more comprehensively reflect the overall bending performance and stability of the steel structure. Therefore, the flexibility of the bending testing equipment is particularly important when conducting multi-point bending tests, and the flexibility of the bending testing equipment is closely related to the efficiency of steel structure bending testing. This flexibility not only improves the efficiency of testing, but also significantly reduces the workload of testing personnel, making the entire testing process smoother and more efficient.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a bending detection device for a building steel structure includes a gantry support 1, on which a detection hydraulic cylinder 2 is fixedly installed. A mounting base plate 7 is installed at the lower end of the gantry support 1. A U-shaped mounting bracket 3 is installed inside the gantry support 1 and on the piston rod of the detection hydraulic cylinder 2. An adjusting assembly 4 is installed on the U-shaped mounting bracket 3, and a downward pressure detection assembly 5 is installed on the adjusting assembly 4. The downward pressure detection assembly 5 consists of a moving block 11, a pressure sensor 13, and a detection compression block 14. The pressure sensor 13 is fixedly installed on the moving block 11, and the detection compression block 14 is fixedly installed on the pressure sensor 13. Two fixing assemblies 6 are symmetrically fixedly installed inside the gantry support 1 and at the upper end of the mounting base plate 7. Each fixing assembly 6 consists of a fixing cylinder 15 and a fixing clamp 16. The fixing clamp 16 is fixedly installed on the piston rod of the fixing cylinder 15. The gantry support 1 and the mounting base plate 7 are fixedly connected. The detection hydraulic cylinder 2 is fixedly installed on the gantry support 1. At the upper end of the gantry bracket 1, the piston rod of the detection hydraulic cylinder 2 passes downward through the upper side wall of the gantry bracket 1. When performing multi-point bending tests on the steel structure, the steel structure can be fixed first using the fixing component 6. Then, the position of the pressing detection component 5 can be adjusted according to the position of the steel structure to be bent. The method is to simply start the adjusting component 4. As the adjusting component 4 works, the position of the pressing detection component 5 will change. After the position of the pressing detection component 5 is appropriate, the adjusting component 4 can be turned off. Then, the detection hydraulic cylinder 2 can be started, thereby using the piston rod of the detection hydraulic cylinder 2 to push the U-shaped mounting bracket 3, the adjusting component 4, and the pressing detection component 5 downward, so that the detection extrusion block 14 presses on the steel structure. At this time, the pressure applied to the steel structure can be obtained through the pressure sensor 13, and the data of the steel structure before and after being extruded by the pressing detection component 5 can be obtained through the laser displacement sensor, thereby obtaining the test results.
[0022] Therefore, by setting a U-shaped mounting bracket 3 on the piston rod of the hydraulic cylinder 2, setting an adjustment component 4 on the U-shaped mounting bracket 3, and setting a pressure detection component 5 on the adjustment component 4, the position of the pressure detection component 5 can be flexibly adjusted according to the points to be detected on the steel structure. This can improve the efficiency of multi-point bending detection of the steel structure and significantly reduce the workload of the inspection personnel. By setting a fixing component 6, the steel structure can be conveniently fixed, thereby avoiding displacement of the steel structure during the bending detection process and ensuring the accuracy of the bending detection results of the steel structure.
[0023] Specifically, the U-shaped mounting bracket 3 has an opening facing downwards, and two mounting through holes 8 are symmetrically opened on both sides of the U-shaped mounting bracket 3. The adjusting component 4 consists of a drive motor 9 and a lead screw 10. The lead screw 10 is fixedly installed on the output shaft of the drive motor 9 and is simultaneously rotatably installed in the two mounting through holes 8 opened on the U-shaped mounting bracket 3. The drive motor 9 is fixedly installed at one end of the U-shaped mounting bracket 3. The moving block 11 on the pressure detection component 5 is movably installed in the U-shaped mounting bracket 3. The moving block 11 has a threaded hole 12, and the moving block 11 is simultaneously installed on the lead screw 10 on the adjusting component 4 through the threaded hole 12. When adjusting the position of the pressure detection component 5, the drive motor 9 is started first. At this time, the drive motor 9 will drive the lead screw 10 to rotate on the U-shaped mounting bracket 3. As the lead screw 10 rotates, the moving block 11 will move the pressure sensor 13 and the detection extrusion block 14.
[0024] Specifically, the fixing component 6 is located inside the gantry bracket 1, the fixing cylinder 15 is fixedly installed on the upper end of the mounting base plate 7, and the upper end of the fixing clamp 16 is provided with a placement groove 17. The placement groove 17 is also opened at the inner end of the fixing clamp 16. When fixing the steel structure, the steel structure is first placed into the two placement grooves 17 on the two fixing components 6, and then the fixing cylinder 15 is activated. The piston rod of the fixing cylinder 15 pushes the fixing clamp 16, so that the two fixing clamps 16 clamp and fix the steel structure.
