Description

Technical Field

[0001] The utility model relates to the technical field of foundation flatness detection, in particular to a foundation detection device. Background Art

[0002] The foundation refers to the soil or rock mass beneath a building that supports its foundation. The soil layers that serve as building foundations are divided into rock, crushed stone, sand, silt, clay, and artificial fill. There are two types of foundations: natural and artificial (composite). Natural foundations are natural soil layers that do not require human reinforcement. Artificial foundations require human reinforcement, and common methods include stone chip cushions, sand cushions, and mixed lime-soil backfill followed by compaction. The building foundation is the foundation of engineering construction, and the flatness of the foundation will affect the quality and stability of subsequent buildings. Therefore, it is extremely important to test the flatness of the foundation after the foundation treatment is completed.

[0026] The present invention will be described in further detail below in conjunction with the full text.

[0027] Combined with attachment Figure 1 and Figure 2, a foundation detection device includes a connecting frame 1 and a movable plate 2. A driving device 3 for driving the movable plate 2 to move within the connecting frame 1 is installed in the connecting frame 1. A measuring rod 4 is slidably connected to the movable plate 2, and a linkage plate 5 is installed on one side of the measuring rod 4. The movable plate 2 is connected to one side of the rolling nut 305. Adjustable airbag horns 6 are installed at the upper and lower ends of the linkage plate 5. Specifically, the airbag horn 6 is a prior art. When the driving device 3 drives the measuring rod 4 to move in the connecting frame 1 to detect the plane of the foundation, if the foundation is uneven, the measuring rod 4 drives the linkage plate 5 to move up and down, squeezing the airbag horn 6, causing the airbag horn 6 to sound, reminding the tester that the flatness of the foundation is abnormal and needs to be directly resolved by on-site personnel.

[0028] When the utility model is implemented, Figure 1 and Figure 2 As shown, the driving device 3 includes a screw mechanism 301 and two sets of telescopic rods 302 connected to the connecting frame 1. The screw mechanism 301 includes a driving motor 303, a screw 304 at the output end of the driving motor 303, a rolling nut 305 used in conjunction with the screw 304, and a limit plate 306 for connecting the screw 304 with a bearing. A motor bracket 7 is installed on the outside of the driving motor 303. The output ends of the two telescopic rods 302 are respectively connected to the limit plate 306 and one side of the motor bracket 7. A guide rod 8 is installed on the motor bracket 7, and the guide rod 8 passes through the rolling nut 305 to connect the limit plate 306.

[0029] When the utility model is implemented, Figure 3 As shown, a sliding hole 201 is provided on the movable plate 2 to cooperate with the movement of the measuring rod 4, a fixed plate 9 is installed on the outside of the measuring rod 4, an adjusting spring 10 is installed on the outside of the measuring rod 4 and between the fixed plate 9 and the movable plate 2, and the lower end of the measuring rod 4 is movably connected with a ball 17. Specifically, the measuring rod 4 moves and adjusts in the sliding hole 201, and the adjusting spring 10 pushes the fixed plate 9 and thereby pushes the ball 17 of the measuring rod 4 to stick to the foundation. A groove is provided at the lower end of the measuring rod 4 to cooperate with the ball 17, and the ball 17 can move in the groove.

[0030] When the utility model is implemented, Figure 3As shown, the linkage plate 5 is relatively installed with a vertical plate 11, and a detachable movable plate 12 is installed on one side of the vertical plate 11. The two airbag horns 6 are installed on the opposite surfaces of the two movable plates 12. The airbag horns 6 can be fixedly connected to the movable plate 12 by a clamp or bolts. A threaded rod 13 and a limiting rod 14 are installed on one side of the movable plate 12. A waist hole 15 and a waist hole 2 16 for matching the threaded rod 13 and the limiting rod 14 are provided on the vertical plate 11. A fixing nut is installed on the outside of the threaded rod 13. The vertical plate 11 can pass through the waist hole 15 through the threaded rod 13, and then be installed on the outside of the threaded rod 13 through the fixing nut, so that the movable plate 12 is fixed on one side of the vertical plate 11. The limiting rod 14 is in the waist hole 2 16 and moves up and down in the waist hole 2 16 to play a role in limiting the position.

[0031] Example 1:

[0032] Place this device in the foundation area that needs to be tested. The telescopic rod 302 of the driving device 3 drives the screw mechanism 301 to move horizontally. The screw mechanism 301 drives the movable plate 2 to detect the flatness in the foundation area. The lower end of the measuring rod 4 is provided with a groove that matches the sphere 17. The sphere 17 can move in the groove. The sphere 17 is located on the foundation. The measuring rod 4 moves in the foundation area. When unevenness occurs, the measuring rod 4 moves and adjusts in the sliding hole 201. The measuring rod 4 drives the linkage plate 5 to move up and down, squeezing the airbag horn 6, causing the airbag horn 6 to sound, reminding the tester that the flatness of the foundation is abnormal and needs to be directly resolved by on-site personnel.

[0033] Example 2:

[0034] Compared with the first embodiment, the second embodiment adds an adjustable position of the airbag horn 6, so as to adjust the error of the flatness detection in the foundation area. The vertical plate 11 can pass through the waist hole 15 through the threaded rod 13, and the limit rod 14 is in the waist hole 2 16. It moves up and down in the waist hole 2 16 to play the role of limiting the position. Then, it is installed on the outside of the threaded rod 13 through the fixing nut, so that the movable plate 12 can be fixed on one side of the vertical plate 11 with an adjustable position, thereby changing the position of the airbag horn 6 and the linkage plate 5, thereby changing the sensitivity of the device and adjusting the error in disguise.

[0035] The above description of the present invention and its embodiments is non-limiting. What is shown in the full text is only one embodiment of the present invention, and the actual structure is not limited thereto.
