[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 , Figure 2 As shown, a concrete rebound test area layout device includes a positioning plate 1, an ink pad 2, and a measuring ruler 3.

[0018] like Figure 1 , Figure 2 As shown, the positioning plate 1 is square, with a positioning hole 11 at the center. The ink pad 2 passes through the positioning hole 11 and abuts against the concrete surface. The ink pad 2 is equipped with a mounting plate 21, and the positioning plate 1 is equipped with a guide rod 12 that passes through the mounting plate 21. A spring 13 is sleeved on the guide rod 12 and located between the positioning plate 1 and the mounting plate 21.

[0019] like Figure 1 , Figure 2 As shown, the measuring ruler 3 is set on two adjacent sides of the positioning plate 1. The measuring ruler 3 includes four ruler sections 31, each of which is 50 centimeters long. A hinge 32 is provided between two adjacent ruler sections 31.

[0020] like Figure 1 , Figure 2 As shown, both ends of the ruler 31 are equipped with magnets 33 that attract each other, so as to fix the ruler 31 together when it is unfolded, thereby increasing the stability of the ruler 31 during use. The outer walls of the four sections of the ruler 31 are fitted with rubber bands 34 for binding and fixing the ruler 31, so as to facilitate carrying and transporting the measuring ruler 31.

[0021] like Figure 1 , Figure 2 As shown, one end of the ruler 31 is provided with a plug rod 35, and the positioning plate 1 is provided with plug holes 36 around its perimeter for the plug rod 35 to be inserted. Therefore, the measuring ruler 3 is detachably connected, which enables the measuring ruler 3 to be carried and transported separately.

[0022] When it is necessary to locate the test area at the edge of the concrete slab, the insert 35 of the bundled measuring ruler 3 is directly inserted into the side of the mounting plate 21 to fix the measuring ruler 3. Then, the positioning plate 1 is placed against the concrete slab, and the value on the measuring ruler 3 is observed to locate the test area at the edge. Then, the mounting plate 21 is pressed, causing the mounting plate 2 to slide forward and pass through the positioning hole 11. Then, the printing plate 2 is used to imprint a series of test frames on the surface of the concrete slab, and then the resilience test of the concrete slab can be performed.

[0023] When it is necessary to locate the test area in the middle of the concrete slab, remove the rubber band 34, then unfold the measuring ruler 3, and use the magnet 33 to fix the rulers 31 together. Then, place the positioning plate 1 against the concrete slab and observe the values ​​on the measuring ruler 3. Then press the mounting plate 21, causing the mounting plate 21 to slide forward and pass through the positioning hole 11. Then, use the printing plate 2 to imprint a series of test frames on the surface of the concrete slab, and then the resilience test of the concrete slab can be performed.

[0024] Therefore, by setting up a positioning plate 1 that can quickly determine the position to be tested, the distance between the area to be tested and the edge of the concrete slab, as well as the distance between adjacent areas to be tested, can be quickly determined, thereby enabling the rapid determination of the position of the printing pad 2 and allowing the test frame to be printed easily and quickly on the concrete slab, thus improving the testing efficiency.

[0025] like Figure 1 , Figure 2As shown, a grinding strip 14 is provided on the inner side wall of the positioning plate 1, and a handle 15 is provided on the outer side wall of the positioning plate 1. Therefore, by setting the positioning plate 1 with grinding function, the dust and mud on the surface of the concrete slab can be ground off, thereby improving the detection accuracy.
