[0022] Specifically, the cylindrical scale 1, the first sleeve 2, the second sleeve 3, the first clamping cutter 4 and the second clamping cutter 5 are all made of stainless steel material. They have large rigidity and are not easy to deform in the daily measurement process. The cylindrical scale 1 is a cylindrical shape with a diameter of 6 mm and a length of 650 mm.
[0023] Specifically, the first clamping cutter 4 and the second clamping cutter 5 have a long side length of 250 mm, a short side length of 200 mm and a width of 7 mm.
[0024] Specifically, in use, the first sleeve 2 is slid to drive the first clamping cutter 4 to be fixed at the zero scale position of the cylindrical scale 1, and the first clamping cutter 4 is placed on one edge of the concrete, so that the cylindrical scale 1 traverses the concrete, and the second sleeve 3 is slid to drive the second clamping cutter 5 to be placed on the other edge of the concrete. The first clamping cutter 4 and the second clamping cutter 5 are both placed on the slump cone, so that the scale can be ensured to be horizontal and the reading of the cylindrical scale 1 can be performed.
[0025] Specifically, a platform 6 is formed on the outer wall of the cylindrical scale 1, threaded holes 7 are formed on the first sleeve 2 and the second sleeve 3, and fixed bolts 8 are connected in the threaded holes 7. The first sleeve 2 and the second sleeve 3 can be fixed by rotating the fixed bolts 8, so as to limit the movement of the first sleeve 2 and the second sleeve 3 and facilitate the reading of the values.
[0026] Specifically, the two ends of the cylindrical scale 1 are connected with baffles 16. The first sleeve 2 and the second sleeve 3 can be prevented from falling off.
[0027] The device for measuring the concrete spread degree, by arranging the cylindrical scale 1, the first sleeve 2, the second sleeve 3, the first clamping cutter 4 and the second clamping cutter 5, the reading is fixed on both sides of the maximum width of the concrete by the movement of the first clamping cutter 4 and the second clamping cutter 5 on the cylindrical scale 1, and the clamping cutter is fixed by the bolt on the sleeve. The caliper does not need to contact the slump cone and will not disturb the slump cone. The clamping cutter can be completely perpendicular to the scale, so as to avoid the error caused by the reading angle. The spread degree of the concrete is determined according to the reading on the scale, so as to improve the accuracy of the spread degree measurement.
[0028] Please refer to Figure 2 , 3, 4, the first sleeve 2 and the second sleeve 3 are connected with the corresponding first clamp cutter 4 and the second clamp cutter 5 through a set of rotating seat assemblies.
