[0023] The supporting structure includes a load-bearing column 1, a reaction frame 2, a fixed base plate 3, and a top plate 4. The bottom of the load-bearing column 1 is connected to the fixed base plate 3. Several first reinforcing plates 13 are evenly arranged at the connection between the bottom of the load-bearing column 1 and the fixed base plate 3 to ensure the connection strength and stability of the load-bearing column 1. Several fixing holes 16 are evenly opened on the fixed base plate 3, which are used to engage with bolts to fix the fixed base plate 3 to the ground or experimental platform. The reaction frame 2 is arranged obliquely and its top is connected to one side of the upper part of the load-bearing column 1. The bottom of the reaction frame 2 is connected to the fixed base plate 3. A top plate 4 is provided at the top of the supporting column 1. A second reinforcing plate 14 is provided on both sides of the lower surface of the top plate 4 and at the connection with the supporting column 1 to ensure the connection strength and stability of the top plate 4. The top plate 4 extends to the outside of the supporting column 1 at the end away from the reaction frame 2. A third reinforcing plate 15 is provided on both sides of the upper surface of the support plate 6 and at the connection with the supporting column 1. Guide rails 5 are symmetrically arranged on both sides of the end of the supporting column 1 away from the reaction frame 2.

The two sides of the slide 10 are slidably engaged with the guide rail 5 via sliders. The middle position of the slide 10 near the support column 1 is engaged with the lead screw 9 via a lead screw nut 11. The hydraulic jack 12 is vertically connected to the end of the slide 10 away from the support column 1 via bolts.
[0025] Installation method and operating principle: First, weld the supporting column 1 and the reaction frame 2 together. Then, weld the bottoms of both the supporting column 1 and the reaction frame 2 to the fixed base plate 3. Weld the top plate 4 to the top of the supporting column 1. Weld the support plate 6 to the surface of the supporting column 1 away from the reaction frame 2, completing the assembly of the main support body. Next, install the hydraulic jack 12 to the outer surface of the slide block 10 with bolts. Connect the lead screw 9 to the lead screw nut 11 of the slide block 10. Then, connect the slide block 10 to the two guide rails 5 through the sliders on both sides. Next, install the guide rails 5 to the surface of the supporting column 1 away from the reaction frame 2 with bolts. At the same time, connect the bottom of the lead screw 9 to the lead screw seat 7 on the upper surface of the support plate 6. Finally, install the motor 8 on the upper surface of the top plate 4. Then, pass the output shaft of the motor 8 through the top plate 4 and connect it to the top of the lead screw 9 through a coupling, completing the installation.

The height of the hydraulic jack 12 is adjusted according to the height of the concrete column to be tested or the test position. Specifically, the motor 8 drives the lead screw 9 to rotate. The lead screw 9 cooperates with the lead screw pair nut 11 on one side of the slide block 10 to adjust the height of the hydraulic jack 12. Then, the piston of the hydraulic jack 12 is adjusted by the oil cylinder connected to the hydraulic jack 12. The piston rod of the hydraulic jack 12 is pressed against the concrete column to be tested. Then, the value of the pressure gauge at the end of the oil cylinder is observed, so as to carry out the overturning test on the concrete column within the predetermined pressure value. This utility model has a reasonable structure. A reaction frame 2 is provided on one side of the supporting column 1.

Furthermore, a guide rail 5 is provided on the side of the supporting column 1 away from the reaction frame 2. A motor 8 is provided at the top of the supporting column 1 through a top plate 4. The output shaft of the motor 8 is connected to a lead screw 9. The slide 10 slides with the guide rail 5 through a slider. The slide 10 also cooperates with the lead screw 9 through a lead screw pair nut 11. The hydraulic jack 12 is connected to the surface of the slide 10 through bolts. Through the cooperation of the motor 8, the lead screw 9 and the lead screw pair nut 11 on one side of the slide 10, the height of the slide 10 can be adjusted. Thus, the height of the hydraulic jack 12 can be adjusted according to the height of the concrete column to be tested or the test point, greatly improving the flexibility and applicability of the test.
