[0033] Example 1

[0034] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a steel reinforcement strength testing device for building engineering, including a support component 100. In this embodiment, the support component 100 includes a bracket 101, which is set on a workbench or installed on the ground using a lower end rod. A support platform 102 is also provided on the bracket 101, and a support body 103 is provided on the support platform 102. An up-and-down sliding member 104 is also provided on the support body 103. The up-and-down sliding member 104 can slide up and down and synchronously drive the support body 103 to move in the longitudinal direction.

[0035] Furthermore, the present invention also includes a test assembly 200, which includes an upper test component 201 connected to the support body 103, an extension rod 202 slidably connected to the support body 103, a test plate 203 disposed at the lower end of the extension rod 202, a snap-fit ​​hole 204 opened on the test plate 203, and a rotating component 205 disposed on the test plate 203. The extension rod 202 is disposed at both ends of the support body 103, and the test plate 203 is disposed corresponding to each extension rod 202, and the two test plates 203 are disposed opposite to each other.

[0036] Preferably, the support body 103 is disposed on the middle side wall of the support platform 102. The sliding member 104 includes a lead screw 104a disposed on the support platform 102, a slider 104b disposed on the support body 103, and a first motor 104c disposed at the lower end of the lead screw 104a. The lead screw 104a is vertically disposed and driven by the first motor 104c. The rotation of the lead screw can drive the slider 104b to slide in the longitudinal direction. In order to limit the movement of the slider 104b, a guide rod is disposed on the support 101. The guide rod passes through the slider 104b and restricts and guides the slider 104b.

[0037] In this embodiment, the support body 103 includes a support rod 103a connected to the slider 104b and a hanging frame 103b connected to the support rod 103a. Both ends of the hanging frame 103b extend outward, and a slide rail 103c is provided at the lower end of the hanging frame 103b. The upper test component 201 is disposed on the hanging frame 103b.

[0038] In this embodiment, the upper test component 201 includes a first frame body 201a disposed on the mounting bracket 103b, a first cylinder 201b disposed on the first frame body 201a, a second frame body 201c slidably connected to the first frame body 201a, and a mounting plate 201d disposed at the lower end of the second frame body 201c. The mounting plate 201d is hinged to the second frame body 201c. Both the first frame body 201a and the second frame body 201c are hinged frames.

[0039] Furthermore, the extension rod 202 is disposed at both ends of the mounting bracket 103b. A second cylinder 300 is disposed on the mounting bracket 103b to push the extension rod 202 to slide. There are two second cylinders 300. A snap-fit ​​bracket is disposed at the upper end of each mounting bracket 103b. The output shaft of the second cylinder 300 is connected to the snap-fit ​​bracket, so that the extension rod 202 can be pushed outward horizontally. A matching slot 301 is provided on the extension rod 202 to cooperate with the slide rail 103c. A connecting block 302 connected to the test plate 203 is disposed at the lower end of the extension rod 202, and the rotating component 205 is disposed in the connecting block 302.

[0040] In this embodiment, the rotating component 205 includes a first rotating gear 205a disposed within the connecting block 302, a second rotating gear 205b meshing with the first rotating gear 205a, and a connecting pipe 205c coaxially disposed with the second rotating gear 205b. The connecting pipe 205c is connected to the snap-fit ​​hole. A locking element 400 is disposed within the connecting pipe 205c. When the operator performs the test, the two ends of the reinforcing bar are inserted into the two connecting pipes 205c respectively, and then the locking element 400 is used to lock the two ends of the reinforcing bar. Then, the first rotating gear 205a and the second rotating gear 205b drive the connecting pipe 205c to rotate, thereby achieving the torsion of the reinforcing bar and testing the torsional performance of the reinforcing bar.

[0041] Furthermore, a sliding groove 205d is provided on the connecting block 302, and only half of the teeth are provided on the first rotating gear 205a. The sliding groove 205d is directly opposite the side of the first rotating gear 205a without teeth. A drive handle is provided on the first rotating gear 205a. The sliding grooves 205d on the two connecting blocks 302 are not mirror images of each other. Thus, when the operator controls the first rotating gear 205a to rotate, the two connecting pipes 205c can rotate in different directions, thereby applying torque in different directions to both ends of the steel bar, thereby testing the torsional resistance.

[0042] Several insertion holes 206 are provided on the lower surface of the two second frame bodies 201c, and several mating holes are provided on the upper surface of the bracket 101 corresponding to the insertion holes 206.

[0043] In this embodiment, the clip 400 includes a rotating plate 401 rotatably connected to the connecting tube 205c, a first guide groove 402 formed on the rotating plate 401, and a fixing plate 403 disposed in the connecting tube 205c. A second guide groove 404 is formed on the fixing plate 403. The first guide groove 402 is arc-shaped, and the two ends of the first guide groove 402 correspond to the two ends of the second guide groove 404. The second guide groove 404 is formed along the radial direction of the fixing plate 403. A connecting rod 405 is disposed between the first guide groove 402 and the second guide groove 404. A base plate 406 is disposed in the connecting tube 205c. A plurality of adjusting rods 407 are rotatably connected to the side wall of the base plate 406. The connecting rods 405 are disposed corresponding to the adjusting rods 407.

[0044] Furthermore, an ear plate extends downward from the lower end of the adjusting rod 407, and a central rotating rod is hinged between the lower end of the adjusting rod 407 and the connecting rod 405. A ring gear 408 is provided on the outer edge of the rotating plate 401, and the ring gear 408 extends outward from the connecting pipe 205c.

[0045] Operation process: When testing the strength of the reinforcing bars, when measuring the bending capacity of the reinforcing bars, the operator can insert several reinforcing bars into the insertion holes 206 at the lower end of the second frame 201c, and then insert the other end of the reinforcing bars into the mating holes on the bracket 101. Then, the first cylinder 201b is activated. After the first cylinder 201b is pressed down, it will bend the reinforcing bars. Then, the force sensor set at the lower end of the second frame 201c is used to measure the stress on the bent reinforcing bars. The stress curve can be plotted according to the gradual increase of the applied force.

[0046] When measuring the torsional resistance of reinforcing bars, both ends of the reinforcing bar are inserted into two connecting pipes 205c. The operator then rotates the ring gear 408, causing the rotating plate 401 to rotate. This causes the positions of several connecting rods 405 to change from near the edge to near the center of the rotating plate 401, or from the center to the edge. The movement of the connecting rods 405 causes the lower end of the adjusting rod 407 to change position. When the connecting rod 405 moves to the position near the edge, it pulls the adjusting rod 407 to rotate, causing the lower end of the adjusting rod 407 to rotate from near the center to near the edge. This adjusts the upper ends of the connecting rods 405 from a state of being far apart to a state of being close together, thus tightening the two ends of the reinforcing bar. Then, through the first rotating gear 205a and the second rotating gear 205b, the connecting pipe 205c is rotated, thereby achieving the torsion of the reinforcing bar and testing its torsional performance.
