[0027] It should be noted that: when the strength of the shear wall body 1 is to be tested, the electric hydraulic rod connected to the pressure sensor 13 is started through the controller 14, and the output end of the electric hydraulic rod will drive the pressure sensor 13 to apply pressure forward. When the pressure sensor 503 is in contact with the shear wall body 1, the pressure between the pressure plate 13 and the shear wall body 1 will be displayed on the display on the surface of the controller, thereby obtaining the value of the pressure that the shear wall body 1 can withstand, so that the staff can record it.

[0028] In this implementation scheme: After investigation, the public (announcement) number: CN220270988U discloses a shear wall quality testing device for construction. However, this testing device needs to open a groove in the ground for each shear wall tested, which not only leads to a long preparation time, but also requires the groove to be backfilled after the test is completed, which is very time-consuming and material-consuming. In order to solve this technical problem, a positioning component 2 and a fixing component 3 are added on this basis.

[0029] More specifically:

[0030] like Figures 1 to 4 As shown;

Two first springs 24 are provided on adjacent sides of each group of limiting shells 25, and both ends of the first springs 24 are connected to the two limiting shells 25.

[0040] In this embodiment: when the triangle plate 15 is inserted into the limit frame 21, the two rollers 26 will respectively contact the limit frame 21 and the positioning block 22 and be squeezed by them. The rollers 26 will be squeezed and act on the limit shell 25 through the positioning shaft 23. The two limit shells 25 will be forced to slide toward the center inside the positioning groove 27. The first springs 24 connected to the two limit shells 25 will be compressed until the triangle plate 15 is inserted into the limit frame 21. Due to the shape of the limit frame 21, the two first springs 24 will indirectly make the two rollers 26 fit against the surfaces of the limit frame 21 and the positioning block 22 due to elastic potential energy, making it smoother when moving the triangle plate 15.

[0041] Going further:

[0042] In an optional embodiment, it further includes a fixing component 3 disposed on the surface of the triangular plate 15;

[0043] The fixing assembly 3 includes a fixing block 31 fixedly connected to the side of the triangle plate 15 away from the pressure sensor 13, the internal thread of the fixing block 31 is connected with a screw rod 32, the bottom end of the screw rod 32 is rotatably connected with a limiting sleeve 33, the limiting sleeve 33 and the fixing block 31 are slidably connected, the internal sliding connection of the limiting sleeve 33 is connected with a positioning rod 35, the internal part of the limiting sleeve 33 is provided with a second spring 34, the two ends of the second spring 34 are respectively fixedly connected with the limiting sleeve 33 and the positioning rod 35, the end of the positioning rod 35 away from the second spring 34 is fixedly connected with an extrusion block 36, and the extrusion block 36 is in contact with the ground.

[0044] In this embodiment: when the triangle plate 15 needs to be fixed, the screw rod 32 is rotated, the screw rod 32 will move downward inside the fixed block 31, and the limiting sleeve 33 rotatably connected to the screw rod 32 will slide downward inside the fixed block 31 until the extrusion block 36 contacts the ground, and the screw rod 32 is continued to be rotated to compress the second spring 34 inside the limiting sleeve 33, and a greater force will be applied to the extrusion block 36 through the positioning rod 35, thereby reinforcing the stability of the triangle plate 15.

[0045] It should be noted that: the extrusion block 36 is fixedly connected to the ground with several triangles to increase the friction between the extrusion block 36 and the ground.

[0046] The working principle and use process of the utility model are as follows: when the shear wall body 1 needs to be inspected, the limit frame 21 is fixed on the ground by bolts, and the length of the limit frame 21 can be selected according to the length of the shear wall body 1, and the vertical plate 11 is fitted with the shear wall body 1, and the horizontal plate 12 connected to the vertical plate 11 will be placed on the ground, and the triangle plate 15 will be inserted into the inside of the horizontal plate 12, and the triangle plate 15 will be inserted into the inside of the limit frame 21, and the positioning block 22 connected to the limit frame 21 will be inserted into the inside of the triangle plate 15, so as to achieve the limitation of the triangle plate 15, and when the triangle plate 15 is inserted into the limit frame 21, the two rollers 26 will contact with the limit frame 21 and the positioning block 22 respectively, and be squeezed by them, and the roller 26 will be squeezed to act on the limit shell 25 through the positioning shaft 23, and the two limit shells 25 will be subjected to force.

When the triangle plate 15 needs to be fixed, the screw 32 is rotated, and the screw 32 will move downward inside the fixed block 31. The limit sleeve 33 rotatably connected to the screw 32 will slide downward inside the fixed block 31 until the extrusion block 36 contacts the ground.
