In the construction of the flat stone base of the curbstone in road engineering, the construction elevation and flatness are often measured and leveled according to the reference line, which results in slow construction speed. Moreover, the workers often have to bend over a lot during the operation, which leads to low construction efficiency and causes back fatigue for the workers in the long run.

[0003] Therefore, there is an urgent need for a leveling tool that allows for rapid construction and is physically friendly to workers. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See below Figures 1-4 This invention provides a detailed description of the small paving and leveling tool for municipal engineering construction.

[0024] This utility model relates to a small paving and leveling device for municipal engineering construction, comprising a main beam 5 that moves back and forth on a curbstone 12, and a scraper 6 that slides vertically on the side of the main beam 5. Rollers 3 are installed at both ends of the main beam 5 to facilitate its movement back and forth on the curbstone 12.

[0025] This utility model's scraper 6 consists of a vertical plate and an inclined plate. The inclined plate is welded to the vertical plate or integrally bent into shape. The vertical plate is flush with the front of the curbstone 12. A steel plate groove 7 extending vertically is formed on the vertical plate. A locking knob 10 passes through the steel plate groove 7 and connects to the main beam 5 to fix the scraper 6 to the main beam 5. The lateral width of the scraper 6 can be customized. When the scraper 6 moves forward, mortar with excessively high base elevation will be scraped off along the bottom edge of the inclined plate; when the scraper 6 moves backward, the scraped base mortar is further leveled by the bottom edge of the inclined plate.

[0026] In addition, the scraper 6 has a groove 9 parallel to the steel plate groove 7 on its vertical plate, and a sliding ruler 11 extending into the groove 9 is fixed to the side of the main beam 5. The width of the sliding ruler 11 is slightly narrower than the width of the groove 9. The sliding ruler 11 is welded to the side of the main beam 5 and can only slide up and down relative to the groove 9. The sliding ruler 11 allows the operator to easily and accurately adjust the height midway. In addition, the locking knob 10 connects to the main beam 5, making the mechanism run more stably when sliding and avoiding the instability of the mechanism when only the locking knob 10 is connected to the main beam 5.

[0027] The small paving and leveling device of this utility model also includes an operating rod 1 for moving the main beam 5 back and forth, and a handrail 2 set on the top of the operating rod 1. A bushing 4 is welded to the back of the inclined plate away from the vertical plate. The horizontal connecting rod at the bottom of the operating rod 1 is fitted and rotated inside the bushing 4. The lower end of the operating rod 1 is connected to the scraper 6 through the bushing 4 welded to the scraper 6. The operating rod 1 and the bushing 4 are rotatably connected. The diameter of the horizontal connecting rod at the bottom of the operating rod 1 is slightly smaller than the inner diameter of the bushing 4. The horizontal connecting rod at the bottom of the operating rod 1 can be fitted and rotated inside the bushing 4, so that the operating rod 1 and the scraper 6 are rotatably connected.

[0028] Specifically, the locking knob 10 of this utility model includes a hand-tightening part with a diameter greater than the width of the steel plate groove 7 and a threaded part connected to the hand-tightening part. The threaded part passes through the steel plate groove 7 and is threadedly connected to a threaded hole on the side of the main beam 5. The scraper 6 is rotated and tightened to the main beam 5 with roller 3 through the locking knob 10 in the steel plate groove 7. After setting the height of the flat stone base, the operator moves the roller 3 back and forth on the curb stone 12, thus forming a small paving scraper for municipal engineering construction.

[0029] After the curbstone 12 is erected and before the leveling stone is laid, the leveling of the base layer can be achieved quickly by pushing and pulling the small paving scraper used in municipal engineering construction. The surface of the vertical plate of the scraper 6 is marked with scales 8, and the scale lines of scales 8 are set along the edge of the slide groove 9 to record the adjustment height of the scraper 6. The 0 mark of scale 8 is the first line at the top of the scale, and the spacing between each scale line is 1 cm. If the height of the slide 11 at the 0 mark is a certain height, the scraper 6 can be adjusted up and down to the corresponding height of the leveling stone base layer. The height of the leveling stone base layer can be preset and locked in place. The roller 3 rolls on the upper part of the curbstone 12, and the operator can push and pull the handle 2 back and forth to carry out the construction.

[0030] Below, refer to Figures 1 to 4 The method of using the small paving and leveling tool for municipal engineering construction of this utility model is described in conjunction with the above description of structural features:

[0031] In use, after setting the height of the flat stone base of the curbstone 12 by rotating the locking knob 10 in the steel plate groove 7 of the vertical plate, the operator uses both hands to operate the 1.2-meter-high handrail 2 (1.2cm in diameter, Q235 round steel) to slide the two rollers 3 back and forth on the curbstone 12, and the scraper 6 to level the base, thus beginning the leveling construction of the flat stone base. When the operator pushes the handrail 2 forward, the mortar with excessive base elevation will be scraped off along the bottom edge of the inclined plate; when the operator pushes the handrail 2 backward, the scraped base mortar is further leveled off by the bottom edge of the inclined plate. When too much base mortar accumulates on the upper surface of the inclined plate, the mortar can be poured out to continue construction. During operation, the vertical plate is flush with the front of the curbstone 12. This leveler is simple to install, easy to operate, highly efficient, and does not require bending over during construction.

[0032] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
