[0002] Construction engineering refers to the engineering entity formed by the construction of various types of housing buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "housing buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities. In the process of building houses, some steel bars are connected by welding. However, the tensile strength of these welded steel bar connectors is unknown. It is time-consuming and labor-intensive to send them to professional testing structures. In addition, each of the steel bar connectors welded on-site at the construction site is different, and there are too many uncertain factors. A single steel bar specimen tested by a professional testing agency cannot represent all of them, and multiple tests will significantly increase the cost. Therefore, a tensile testing device for testing steel bar connectors on-site at the construction site is needed. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] like Figure 1-2 As shown, a tensile strength detection device for welding parts in construction engineering comprises a bottom plate 1, a No. 1 pillar 2 is fixedly installed at the rear position of the bottom plate 1, a No. 2 pillar 3 is fixedly connected to the front position of the bottom plate 1, a top plate 6 is fixedly connected to the upper ends of the No. 1 pillar 2 and the No. 2 pillar 3, a tension sensor 10 is fixedly connected to the bottom plate 1, a lower workbench 11 is fixedly connected to the tension sensor 10, an upper workbench 12 is movably installed above the lower workbench 11, a steel bar welded part 13 is fixedly connected between the lower workbench 11 and the upper workbench 12, a positioning fixture 19 is fixedly connected to the lower workbench 11 and the upper workbench 12, a movable fixture 21 is movably installed on the lower workbench 11 and the upper workbench 12 at the side position of the positioning fixture 19, and the lower workbench 11 and the upper workbench 12 are fixedly connected to the positioning fixture 19. The workbench 12 is fixedly connected to the two ends of the steel bar welded part 13 through the positioning clamp 19 and the movable clamp 21 respectively. The cylinder 20 is fixedly connected to the lower workbench 11 and the upper workbench 12. The limiting plate 22 is also fixedly connected to the lower workbench 11 and the upper workbench 12. The output shaft of the cylinder 20 is fixedly connected to the movable clamp 21, and the output shaft of the cylinder 20 passes through the limiting plate 22. The movable clamp 21 is located at the side of the limiting plate 22. The movable clamp 21 is pushed toward the side of the output shaft of the cylinder 20, so that the movable clamp 21 squeezes the steel bar welded part 13 to the side, thereby fixing the steel bar welded part 13. The limiting plate 22 is located at the side of the cylinder 20 to protect the cylinder 20 to prevent debris from damaging the cylinder body of the cylinder 20 when the steel bar breaks.
[0021] like Figure 1-2As shown, a screw tube 18 is fixedly connected to the upper workbench 12, and the screw tube 18 and the screw rod 15 are movably installed. Four No. 1 slide bars 14 are fixedly connected between the bottom plate 1 and the top plate 6, and the No. 1 slide bar 14 is movably installed with the upper workbench 12. The screw rod 15 is movably installed with the lower workbench 11 and the upper workbench 12 through bearings 17 respectively. A stepper motor 16 is fixedly connected to the upper workbench 12, and the upper end of the screw rod 15 is fixedly connected to the output shaft of the stepper motor 16 through a coupling. The inner wall of the screw tube 18 is engraved with threads, so that the screw tube 18 and the screw rod 15 are installed with each other. With the rotation of the screw rod 15, the screw tube 18 moves upward or downward, so that the upper workbench 12 moves synchronously, so as to perform tensile testing on the steel bar weldment 13.
[0022] like Figure 1-3 As shown, a No. 3 protective plate 8 is movably installed between the No. 2 pillars 3, a No. 1 protective plate 4 is fixedly connected between the No. 1 pillars 2, a No. 2 protective plate 5 is fixedly connected between the No. 1 pillars 2 and the No. 2 pillars 3, and a slide groove 7 is provided on the side of the No. 2 pillar 3. Both ends of the No. 3 protective plate 8 are movably installed in the slide groove 7, and the handle 9 is fixedly connected to the No. 3 protective plate 8. The No. 3 protective plate 8 is easy to move upward or downward. The No. 3 protective plate 8 is movably moved in the slide groove 7, which is convenient for moving the No. 3 protective plate 8 upward, thereby facilitating the installation and disassembly of the steel bar welded part 13. When the anti-trash detection is carried out, the No. 3 protective plate 8 is moved downward, thereby covering the steel bar welded part 13 and improving safety.
[0023] It should be noted that the utility model is a tensile strength detection device for welding parts in construction projects. The stepper motor 16 is started to rotate the screw rod 15, so that the upper workbench 12 moves downward, and the upper workbench 12 slides up and down on the No. 1 slide bar 14. When the upper workbench 12 slides to a suitable position, the upper and lower ends of the steel bar welded part 13 are respectively brought close to the positioning fixtures 19 on the upper workbench 12 and the lower workbench 11, and then the cylinder 20 at the side position is started so that the output shaft of the cylinder 20 pushes the movable fixture 21 to move, so that the movable fixture 21 moves to the side, squeezes the steel bar welded part 13, and thus positions the steel bar welded part 13. The cylinder 20 moves again to squeeze and deform the two ends of the steel bar welded part 13, thereby fixing and connecting the steel bar welded part 13, and then the stepper motor 16 is started. Reverse rotation causes the screw 15 to move in the opposite direction, causing the upper workbench 12 to move upward, thereby pulling the steel bar welded part 13. A tension sensor 10 is provided below the lower workbench 11 to detect the magnitude of the tension on the steel bar welded part 13 in real time. When the welding joint of the steel bar welded part 13 is broken or deformed, or the steel bar welded part 13 is broken or deformed, the stepper motor 16 is stopped to detect the tensile performance of the steel bar welded part 13. When installing the steel bar welded part 13, the handle 9 is pushed to make the No. 3 protective plate 8 slide upward in the slide groove 7. When the upper workbench 12 moves upward, the No. 3 protective plate 8 is pulled downward, so that the No. 3 protective plate 8, the No. 2 protective plate 5 and the No. 1 protective plate 4 protect the steel bar welded part 13, thereby avoiding safety accidents caused by the broken steel bars bursting out.
