Detailed ways

Example

Fig. 1 is a schematic structural diagram of an embodiment of a concrete rough surface inspection tool of the present invention, and Fig. 3 is a schematic diagram of a bottom plate structure of an embodiment of a concrete rough surface inspection tool of the present utility model. A concrete rough surface inspection tool includes a bottom plate 1 and a probe 6. The bottom plate 1 is a rectangular plate-shaped structure, and the length×width dimension is 200×100 or 250×100, so as to adapt to the thickness specifications of existing building walls. The bottom plate 1 includes an upper plate 9 and a lower plate 10, and the upper plate 9 and the lower plate 10 are glued and fixed together. A hundred meshes are arranged between the upper board 9 and the lower board 10 . The 100-grid grid can be fixed between the upper plate 9 and the lower plate 10 by a metal mesh, or it can be carved or drawn on the lower surface of the upper plate 9 or the upper surface of the lower plate 10 . The upper plate 9 and the lower plate 10 are made of transparent hard plastic to avoid deformation during the detection process and improve the accuracy of detection. Setting the hundred-grid net between the upper plate 9 and the lower plate 10 can avoid the wear of the hundred-grid net and improve the service life.

The upper surface of the bottom plate 1 is provided with a fixed seat 2, and the fixed seat 2 is arranged on the sideline of the 100-grid grid, so as to avoid hindering the observation path of the 100-grid grid. The two ends of the handle 3 are respectively inserted into the mounting holes provided on the two fixing bases 2, and the diameter of the handle 3 is slightly smaller than the aperture of the mounting holes so that the handle 3 can be rotated on the mounting base. When not in use, the handle 3 can be placed flat on the bottom plate 1 to facilitate the storage of the bottom plate 1 . Several detection holes 4 are arranged on the bottom plate 1, and the detection holes 4 are through holes. The detection hole 4 is located at the crossing point of the grid lines of the hundred grids, and the diameter of the detection hole 4 is 2-3mm, which reduces the influence of the detection hole 4 on the detection result and improves the detection accuracy.

Fig. 2 is a schematic diagram of a probe structure of an embodiment of a concrete rough surface inspection tool of the present invention. The probe 6 is a cylindrical structure with a tapered detection end 7 at one end, and a scale area 8 is provided on the side of the probe 6 . The bottom mark of the scale area 8 is 0, and the division value is 1mm. A sleeve 5 is sheathed on the outside of the probe 6, and the sleeve 5 is a cylinder, and the two end faces of the sleeve 5 are perpendicular to the sides. When one end surface of the sleeve 5 is attached to the base plate 1 , the sleeve 5 is perpendicular to the base plate 1 . The outer diameter of the sleeve 5 is slightly larger than the diameter of the detection hole 4 . The detection end 7 of the probe 6 passes through the sleeve 5 and passes through the bottom plate 1 from the detection hole 4 to detect the rough surface of the concrete. The distance from the 0 scale line in the scale area 8 of the probe 6 to the end of the detection end 7 is equal to the thickness of the bottom plate 1 plus the height of the sleeve 5, so that the reading on the probe 6 at the end of the sleeve 5 far away from the bottom plate 1 is concrete The bump depth of the rough surface. The outer diameter of the probe 6 is slightly smaller than the inner diameter of the sleeve 5. The sleeve 5 ensures the verticality between the probe 6 and the base plate 1 on the one hand, and facilitates the reading on the probe 6 on the other hand.

When in use, the base plate 1 is placed on the concrete to be tested, and the ratio of the rough surface to the joint surface is measured through the grid on the base plate 1, that is, the number of grids occupied by the rough surface is read from the grid. Then the sleeve 5 is placed at the detection hole 4 of the bottom plate 1, and the probe 6 is inserted from the sleeve 5 and the detection hole 4 to detect the unevenness of the rough surface on the concrete. The probe 6 is to detect the degree of concrete concavo-convexity at the plurality of detection holes 4 .

Therefore, the utility model adopts the concrete rough surface inspection tool with the above structure, which can solve the problems of inconvenient detection of concrete rough surface and inaccurate detection results.
