[0021] In the embodiment, the back plate 1 is made of stainless steel plate, the frame 2, the second crossbeam 23 and the second column 24 are all made of stainless steel square tube with the same size, which is made of stainless steel material and will not rust during maintenance, and can be used repeatedly for a long time.

[0022] In the embodiment, the back plate 1 is made of stainless steel plate, the frame 2, the second crossbeam 23 and the second column 24 are all made of stainless steel square tube with the same size, which is made of stainless steel material and will not rust during maintenance, and can be used repeatedly for a long time.

[0023] In the embodiment, the back plate 1 is made of stainless steel plate, the frame 2, the second crossbeam 23 and the second column 24 are all made of stainless steel square tube with the same size, which is made of stainless steel material and will not rust during maintenance, and can be used repeatedly for a long time.

[0024] In the embodiment, the lower part of the two first columns 22 and the first crossbeam 21 below are both fixedly provided with clamping grooves 5, the clamping grooves 5 are in U shape as a whole, the clamping grooves 5 are used for inserting the baffles 6, and the baffles 6 prevent the concrete color difference contrast samples with different proportions filled in the concrete filling grooves 4 from falling out of the concrete filling grooves 4 due to vibration and other reasons during long-term use, thereby preventing the concrete samples from being damaged.

[0025] In this embodiment, circular bosses 61 are provided on the left and right sides of the side of the baffle 6 away from the concrete filling groove 4. The function of the circular bosses 61 is that when removing the baffle 6, the baffle 6 can be removed from the slot 5 by pressing the circular bosses 61 on both sides with both hands and pushing upwards.

[0026] In this embodiment, the baffle 6 is made of acrylic material. The advantage is that acrylic material is waterproof, moisture-proof and easy to clean, and the transparent acrylic baffle 6 can clearly see the situation inside the covered concrete filling groove 4. The baffle 6 can cover two-thirds of the area of ​​the concrete filling groove 4. It can be understood that after the concrete filling groove 4 is filled with concrete of different proportions, the exposed one-third of the concrete filling groove 4 can be used for color difference comparison of concrete appearance defect repairs. It is possible to perform color difference comparison more intuitively without observing through acrylic, thereby preventing color difference comparison errors caused by light refraction.

[0027] In this embodiment, the backboard 1 includes an upper backboard 11 and a lower backboard 12. The upper backboard 11 is located above the frame 2 and is used to install and fix the label box 3; the upper and lower ends of the lower backboard 12 are fixed on the second crossbeam 23 and the lower first crossbeam 21, and its left and right sides are respectively fixed on the lower parts of the two first columns 22; a gap of 3-5 cm is left between the upper backboard 11 and the lower backboard 12. The backboard 1 does not adopt a whole piece, but adopts a split type of upper backboard 11 and lower backboard 12, and a gap of 3-5 cm is also left. When the concrete filling tank 4 is filled with black cement and white cement mixtures of different proportions, the mixture needs to be cured regularly. The splashed curing water will flow away from the gap of 3-5 cm, and no water will be accumulated in the area where the label box 3 is fixed. At the same time, when comparing, the backboard of the device is pressed against the area to be repaired, and the real color of the on-site concrete is observed through the gap of 3-5 cm, which is convenient for comparison with the concrete sample in the concrete filling tank 4.

[0028] In this embodiment, a handle 7 is fixedly provided on the upper surface of the first crossbeam 21 above the frame 2. The handle 7 is arranged at a left-right symmetrical central position. The function of the handle 7 is to facilitate the staff to carry it.

[0029] The method of using the present invention is to fill black cement and white cement mortars with different proportions in a concrete filling tank 4 (the mortar ingredients include black cement, white cement, sand, water, etc., and some also require adhesives), and put corresponding labels indicating the proportions, ingredients and sample preparation time in the label box 3 corresponding to each concrete filling tank 4, and place the device under the same environmental conditions as the concrete to be repaired for maintenance. When the black cement and white cement mortars in the concrete filling tank 4 solidify, a concrete sample is formed, and the device is carried to the concrete defect to be repaired, and compared with the concrete at the defect, and the closest concrete sample is selected. Then, according to the proportions and ingredients on the label in the label box corresponding to the concrete sample, the mortar is prepared, and finally, the mortar is used to repair the appearance defects of the concrete at that location. The device can perform on-site concrete color difference comparison, improves the accuracy of concrete color difference comparison, and eliminates the problem of large errors in color difference comparison in traditional construction methods.

[0030] In the above embodiments, the black cement is ordinary Portland cement or the corresponding cement used in the concrete of the part to be repaired, and the white cement is white Portland cement.
