[0014] Example

[0015] like Figure 1 As shown, a high-strength bolt friction surface anti-slip coefficient detection and fastening device includes a base plate 1, a friction surface fixing part 3, an upper fastening bolt 5 and a side fastening bolt 6. The base plate 1 is provided with fixing holes 2 at the four corners. The friction surface fixing part 3 is an inverted U-shaped structure and is fixed in the middle of one side edge of the top surface of the base plate 1. Two detection plates 4 are inserted into the friction surface fixing part 3. The height of the detection plate 4 is the same as the inner height of the friction surface fixing part 3. The thickness of the detection plate 4 is equal to half of the inner width of the friction surface fixing part 3. The upper fastening bolt 5 is arranged in the middle of the top surface of the friction surface fixing part 3 through a threaded connection, and the side fastening bolt 6 is arranged in the middle of the side wall of the friction surface fixing part 3 through a threaded connection.
