Technical Field

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

[0002] The foundation refers to the soil or rock mass that supports the foundation under the building. The soil layers used as the foundation of the building are divided into rock, gravel soil, sand, silt, clay and artificial fill. There are two types of foundations: natural foundations and artificial foundations (composite foundations). 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, mixed lime soil backfill and compaction, etc.

[0003] There is an existing foundation flatness detection device (publication number: CN 219343121 U) comprising two support frames, each of which is fixedly connected to two groups of support legs on its bottom surface, each of which is fixedly connected to a moving wheel at its bottom end, a first support box is provided inside one of the two support frames, and a second support box is fixedly connected to the inner side wall of the other support frame. The device can adjust the height of the first support box through the level bar, level, threaded rod, threaded hole, rotating wheel, rail opening, limit bar, limit hole and limit rod, and adjust the horizontality of the wire rope through the cooperation of the level bar and level, effectively maintain the horizontality of the wire rope, and facilitate the accurate measurement of the foundation flatness by the infrared rangefinder. Through the support legs, moving wheels and push handle, the detection personnel can push the device more conveniently, effectively increase the portability of the device, and facilitate the staff to measure and detect the foundation flatness.

[0004] The above existing devices determine whether the ground is flat by detecting data through the movement of an infrared rangefinder on a horizontal steel wire rope.

[0025] like Figure 5 As shown, a circular groove is provided on the outer wall of the bottom end of the horizontal measurement support block 1, and the lifting and adjusting component 3 includes a lifting threaded sleeve 301, the upper end of the lifting threaded sleeve 301 extends and is rotatably installed in the circular groove at the bottom end of the horizontal measurement support block 1, and a fixed bearing 302 is sleeved on the outer surface of the upper circumference of the lifting threaded sleeve 301, and the fixed bearing 302 is fixedly installed in the circular groove, and a supporting threaded sleeve 303 is meshedly sleeved on the outer surface of the lower end of the lifting threaded sleeve 301, and the upper surface of the supporting chassis 4 and the lower end of the supporting threaded sleeve 303 are fixedly welded to each other, and an annular plug-in hole is provided on the upper surface of the supporting chassis 4, and an annular plug-in frame 8 is inserted in the annular plug-in hole, and a smooth chamfer is provided on the corners of the lower end of the annular plug-in frame 8, so that after the supporting chassis 4 is fixed, the height of the horizontal measurement support block 1 can be adjusted by rotating the lifting threaded sleeve 301, and then the level 14 can be used to determine whether the symmetrically arranged horizontal measurement support blocks 1 are adjusted to the same height, thereby facilitating the staff to measure the flatness of the foundation.

[0026] like Figure 3-Figure 6 As shown, the horizontal block support frame 2 includes an active support frame 201 and a passive support frame 202. A convex clamping block 9 is provided on one end side wall of the active support frame 201, and a convex clamping groove is provided on one end side wall of the passive support frame 202. The convex clamping block 9 and the convex clamping groove are slidably engaged with each other.

[0028] When the utility model is in use, the staff will place the support chassis 4 symmetrically, and then insert the annular plug-in frame 8 into the ground, at which time the support chassis 4 can be limited, and then the staff will dock the active support frame 201 with the passive support frame 202, and then plug one end of the active support frame 201 and the passive support frame 202 into the symmetrically arranged horizontal measurement support block 1, and then the staff will rotate the lifting threaded sleeve 301 in the lifting adjustment component 3 by the offset of the liquid in the level 14 set on the horizontal measurement support block 1, so as to achieve the horizontal measurement between the support blocks 1. Horizontal adjustment is performed to ensure that the active support frame 201 and the passive support frame 202 are in a horizontal state. Then the staff inserts the measuring horizontal block 7 into the sliding groove 10 in the active support frame 201 and the passive support frame 202. By measuring the ups and downs of the horizontal block 7, it can be determined whether the ground is flat. When the staff needs to move the device, the staff will engage the synchronization plate 13 into the limit groove in the measuring horizontal block 7, and then limit the two ends of the synchronization plate 13 through the grooves in the fixed plate 12, which can prevent the measuring horizontal block 7 from falling, thereby facilitating the staff to move the device.
