Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0018] This embodiment includes a scraper plate 1, which is used to smooth the mortar. A vertical rod 2 is fixed upward at the upper end of the scraper plate 1. A short sleeve 3 is slidably sleeved on the outside of the vertical rod 2, and the vertical rod 2 can slide up and down along the short sleeve 3. A threaded hole A is provided on one side of the short sleeve 3, and a bolt A4 is connected in the threaded hole A. The bolt A4 is used to fix the short sleeve 3. The bolt A4 passes through the threaded hole A and abuts against the vertical rod 2. After tightening the bolt A4, the short sleeve 3 and the vertical rod 2 can no longer slide relative to each other.

[0019] A horizontal sliding rod 5 is fixed to the other side of the short sleeve 3. The horizontal sliding rod 5 is perpendicular to the short sleeve 3 and also perpendicular to the scraper plate 1. The horizontal sliding rod 5 is slidably sleeved with the horizontal fixed rod 6. The horizontal fixed rod 6 is hollow inside, and the horizontal sliding rod 5 can extend into the horizontal fixed rod 6. The horizontal sliding rod 5 can slide left and right along the horizontal fixed rod 6. For easy storage, it is preferable that the end of the horizontal fixed rod 6 near the horizontal sliding rod 5 has a threaded hole B. A bolt B10 is connected in the threaded hole B. The bolt B10 is screwed into the threaded hole B and abuts against the horizontal sliding rod 5. Tightening the bolt B10 can fasten the horizontal sliding rod 5 and the horizontal fixed rod 6 together. When storing, the horizontal sliding rod 5 is slid into the horizontal fixed rod 6, and then the bolt B10 is tightened to prevent the horizontal sliding rod 5 from slipping out of the horizontal fixed rod 6.

[0020] Several L-shaped control plates 7 are fixed to the bottom of one side of the horizontal fixing rod 6. One or more L-shaped control plates 7 can be used; in this embodiment, two L-shaped control plates 7 are used. Each L-shaped control plate 7 includes a horizontal plate 11 and a vertical plate 12, wherein the bottom surface of the horizontal plate 11 of the L-shaped control plate 7 is flush with the bottom surface of the horizontal fixing rod 6. The L-shaped control plate 7 is used to be secured to the curb or control stone. Preferably, the corner of the L-shaped control plate 7 has a chamfer 13 identical to that of the curb, which allows the L-shaped control plate 7 to be secured to the curb or control stone more effectively. Preferably, a hanging rod 8 is vertically welded to the outer surface of the L-shaped control plate 7. In this embodiment, a discarded screw rod can be used as the hanging rod 8. One hanging rod 8 is welded to the top and bottom of the vertical plate 12 of the L-shaped control plate 7. The hanging rod 8 is used to hang the line, and the control curb is mounted on the same vertical surface. Preferably, an inclinometer 9 is provided on the upper surface of the L-shaped control panel 7. The inclinometer 9 is used to measure the incline angle of the upper surface of the curbstone, that is, the angle between the upper surface of the curbstone and the horizontal direction. This incline angle is the incline angle after the curbstone is installed. The inclinometer 9 is a commonly used device, and its structure and principle will not be described in detail here. Generally, the incline angle of the curbstone is set at 2-3°. This incline angle can also be measured on-site using angle measuring tools, but in this embodiment, the inclinometer 9 is directly installed on the L-shaped control panel 7, which is more convenient.

[0021] During construction, first adjust the inclination angle of the control stone to meet the design requirements. One or more control stones can be used. Then, clip the L-shaped control plate 7 onto one edge of the control stone, ensuring that the horizontal plate 11 of the L-shaped control plate 7 is flush against the upper surface of the control stone, and the vertical plate 12 is flush against the side of the control stone. At the same time, the horizontal fixing rod 6 is also flush against the upper surface of the control stone. At this point, the inclination angle of the L-shaped control plate 7 is the designed inclination angle of the curb stone, and the scraper plate 1 also has the same inclination angle as the entire tool. Loosen bolt A4 and slide the scraper plate 1 downwards until the height of the scraper plate 1 from the ground is the designed mortar layer thickness. Tighten bolt A4 to fix the scraper plate 1. Loosen bolt B10 to allow the horizontal sliding rod 5 to slide left and right. Workers can press down on the horizontal fixing rod 6 to ensure it is in contact with the upper surface of the control stone. Hang a line on the hanging rod 8, then lay a mortar layer at the curbstone installation location. After laying the mortar layer, pull the horizontal sliding rod 5 left and right. The horizontal sliding rod 5 will move the scraper plate 1 to level the mortar, simultaneously creating the required mortar angle. This ensures the correct angle for the curbstone installed on the mortar layer. Then, install the curbstone on the prepared mortar layer. Once this section of the curbstone is installed, move the tool to place the L-shaped control plate 7 onto the installed curbstone. This installed curbstone now serves as the initial control stone. Repeat the above steps to install the next section of the curbstone. During installation, observe whether the inclinometer 9 meets the designed inclinometer angle requirements. If there is a deviation, adjust the inclinometer to meet the design requirements.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
