[0018] Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment: Please refer to Figures 1-3 , a stiffness testing device for a composite shear wall, comprising a bottom plate 1 and a support box body 2. The support box body 2 is fixedly installed at the upper end of the bottom plate 1. An adjusting and testing structure is provided at the rear side of the upper end of the bottom plate 1, and a support and testing structure is arranged inside the support box body 2;

[0020] The adjusting and testing structure includes: a support vertical frame 3, a mounting plate 4, a motor 5, a lead screw 6, a first hydraulic cylinder 7, and a detection push plate 8;

[0021] The support vertical frame 3 is fixedly installed at the rear side of the upper end of the bottom plate 1. Both ends of the mounting plate 4 are movably sleeved on both sides of the support vertical frame 3. The motor 5 is fixedly installed at one side of the upper end of the bottom plate 1. One end of the lead screw 6 is connected to the driving end of the motor 5, and the other end is movably embedded in the mounting plate 4. The first hydraulic cylinder 7 is fixedly embedded on one side of the mounting plate 4. The detection push plate 8 is connected to the telescopic end of the first hydraulic cylinder 7.

[0022] When testing the composite shear wall, the staff first moves the device to the designated position and uses the provided bottom plate 1 to support the whole device. Subsequently, according to the height of the shear wall sample, the motor 5 at the upper end of the bottom plate 1 is driven to work. Under the cooperation of the lead screw 6 and the internal thread inside the mounting plate 4, the height of the mounting plate 4 at the upper end of the support vertical frame 3 is changed until the whole mounting plate 4 is higher than the height of the composite shear wall sample. Then, the shear wall sample is placed above the support and testing structure and fixed. Subsequently, by driving the first hydraulic cylinder 7 at the upper end of the mounting plate 4 to work, the detection push plate 8 is pushed to fit with the top end of the composite shear wall sample, and continuous force is applied to realize the compressive strength detection operation of the composite shear wall.

[0023] In the specific implementation process, the support and testing structure includes: four fixed support rods 9, a support plate 10, two fixed plates 11, two clamping plates 12, four clamping bolts 13, and four second hydraulic cylinders 14;

The two fixed plates 11 are respectively installed on both sides of the upper end of the support plate 10. The two clamping plates 12 are respectively located inside the two fixed plates 11. The four clamping bolts 13 are respectively movably embedded in the two fixed plates 11. The four second hydraulic cylinders 14 are respectively installed at the four corners of the lower end inside the support box body 2.

[0025] When installing and conducting seismic tests on the composite shear wall sample, the staff first place the bottom end of the composite shear wall sample on the upper end of the support plate 10. Through the cooperation of the four fixed support rods 9 and the support plate 10, the shear wall sample is placed on the upper end of the support box 2. Subsequently, by turning the four clamping bolts 13 in the two fixing plates 11, the two clamping plates 12 are pushed to move inward by the clamping bolts 13 to clamp and fix the bottom end of the composite shear wall sample. When conducting the compressive strength test, the four fixed support rods 9 stably support the support plate 10 and the composite shear wall sample to ensure the test effect. Subsequently, by driving the four second hydraulic cylinders 14 at the four corners inside the support box 2 to work in sequence, the support plate 10 is pushed to swing at a specified angle in the four fixed support rods 9, and the seismic effect test of the composite shear wall can be satisfied.

[0026] In the specific implementation process, guide plates 15 are provided on both sides of the upper end of the detection push plate 8.
