[0002] Floor slab: Floor slab generally refers to a kind of concrete prefabricated part processed and produced by the prefabrication yard. It is the load-bearing part of the floor slab layer.

[0041] Working principle: When it is necessary to test the strength of the floor sample, the staff first places the floor sample to be tested on the upper surface of the bearing platform 12 and between the two L-shaped fixing plates 13, and then respectively turns the two handles 26, the two handles 26 rotate the two threaded rods 25, and the two threaded rods 25 drive the two pressing plates 21 and the two anti-skid pads 22 to vertically descend until the lower surfaces of the two anti-skid pads 22 are in close contact with the upper surface of the floor sample and the two pressing plates 21 press the floor sample through the two anti-skid pads 22, and then stop turning the two handles 26, thereby conveniently realizing the fixation of the floor sample, and then facilitating the subsequent strength test of the floor sample; Subsequently, the staff turns on the servo motor 38, the driving shaft of the servo motor 38 rotates the first rotating rod 4, the first rotating rod 4 rotates the sector gear 41, the sector gear 41 drives the first gear 37 to rotate, the first gear 37 rotates a corresponding lead screw 31, one lead screw 31 rotates the other lead screw 31 synchronously in the same direction through two first synchronous wheels 35 and the first synchronous belt 36, the two lead screws 31 drive the two sliders 33 to slide horizontally along the inner wall of the corresponding slide groove 32, the two sliders 33 move the bearing platform 12 horizontally through four connecting rods 34, the bearing platform 12 makes the floor sample synchronously move horizontally, when the sector gear 41 is disengaged from the first gear 37, the bearing platform 12 and the floor sample stop moving horizontally; At the same time, the fan gear 41 meshes with the second gear 62 and drives the second gear 62 to rotate. The second gear 62 rotates the third rotating rod 59. The third rotating rod 59 rotates the second rotating rod 57 through the two second synchronous wheels 6 and the second synchronous belt 61. The second rotating rod 57 rotates the cam 58. When the cam 58 contacts the inner wall of the arc groove 56, the cam 58 pushes the pushing seat 55 to vertically descend. The pushing seat 55 causes the base plate 51 to vertically descend. The base plate 51 extends the four telescopic rods 53 and the four telescopic springs 54, and impacts the floor sample on the upper surface of the bearing platform 12 through multiple impact blocks 52. As the fan gear 41 intermittently meshes with the first gear 37 and the second gear 62, the floor sample intermittently moves horizontally. The multiple impact blocks 52 intermittently impact the floor sample in the stopped state, thereby conveniently realizing the strength detection of the floor sample at different positions, thereby effectively improving the convenience of the strength detection of the floor sample, and effectively improving the accuracy of the strength detection result.
