Description

Technical Field

[0001] This invention belongs to the field of building engineering, and in particular relates to a curbstone tilting installation device and method. Background Technology

[0002] Vertical installation of curbs is a traditional method, but vertically installed curbs are easily scratched and squeezed by steel wheels during asphalt paving and compaction, causing damage. To address the drawbacks of vertical curb installation, many curb protection devices are currently available to reduce damage to curbs before asphalt paving and compaction. However, current curb protection devices are generally complex in structure and can also hinder paving and compaction, affecting construction efficiency and increasing construction costs. Therefore, it is necessary to research and improve the traditional curb installation method to address these problems. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a curbstone tilting installation device and method.

[0004] This invention relates to a curbstone inclined installation device, comprising a mortar spreading tool and a support tool. The mortar spreading tool includes two parallel trapezoidal baffles, with a horizontal plate connecting the upper horizontal portions of the baffles. A handle is provided on the horizontal plate. A right-angled trapezoidal scraper is connected between the upper inclined portions of the trapezoidal baffles. The lower end of the right-angled trapezoidal scraper is a hypotenuse, and the vertical distance between the two ends of the hypotenuse and the bottom surface of the mortar spreading tool is equal to the thickness of the mortar at the left and right ends below the curbstone. The support tool includes a base plate and an inclined support plate hinged together. A groove along the width of the base plate is provided in the middle of the base plate. Several adjusting threaded holes are evenly provided on the bottom surface of the groove. A slider is provided in the groove, with the slider having two... The end is provided with a fixed threaded hole corresponding to the adjusting threaded hole. The slider is fixed together by bolts passing through the fixed threaded hole and the adjusting threaded hole. Two fixed plates A are symmetrically arranged in the middle of the slider, and a fixed shaft A passes between the two fixed plates A. The two ends of the fixed shaft A are provided with threads, and the two ends of the fixed shaft A are respectively fixed to the fixed plates A by nuts A. Two fixed plates B are symmetrically arranged in the upper middle part of the inclined support plate, and a fixed shaft B passes between the two fixed plates B. The two ends of the fixed shaft B are provided with threads, and the two ends of the fixed shaft B are respectively fixed to the fixed plates B by nuts B. The upper end of a support rod is rotatably connected to the fixed shaft B, and the lower end of the support rod is rotatably connected to the fixed shaft A.

[0005] Preferably, the angle between the hypotenuse of the right-angled trapezoidal scraper and the horizontal plane is consistent with the inclination angle of the curbstone.

[0006] Preferably, the angle between the hypotenuse of the right-angled trapezoidal scraper and the horizontal plane is between 1° and 3°.

[0007] Preferably, the base plate and the inclined support plate are hinged together.

[0008] A method for installing curb stones at an angle includes the following steps: Step 1: Road side formwork construction. When constructing the road side formwork, several supporting steel bars are evenly embedded along the length of the road side formwork on the side away from the curb. The supporting steel bars are perpendicular to the road side formwork, and the horizontal distance between the supporting steel bars and the bottom of the curb is equal to the width of the base plate. Step 2: Spread mortar at the location where the curbstone will be installed on the roadside formwork, and then pull the mortar spreading tool to make the mortar reach the designed inclination angle and thickness; Step 3: Adjust the inclination angle of the inclined support plate of the support tool to match the designed inclination angle of the curbstone, fix the slider, and then place the support tool on the upper surface of the road side formwork, so that the bottom edge of the support tool abuts against the support steel bar; Step 4: Install the curbstone. Place the curbstone at an angle on the mortar from Step 2, with the side of the curbstone closest to the supporting steel bar resting against the inclined support plate. Step 5: After the mortar has reached its strength, remove the support tools and then construct the curb backing.

[0009] As a preferred option: In step one, the length of the supporting steel bars protruding from the road side formwork is 3-6cm.

[0010] The present invention provides a method for inclined installation of curb stones, which solves the problem of damage to curb stones during the later asphalt paving and compaction process, reduces economic costs, improves work efficiency, and enhances the quality of curb stone installation.

[0011] This invention installs the curbstone at an angle, forming an angle with the roller's steel wheel. This avoids scraping and squeezing the curbstone during asphalt compaction, effectively controlling the installation quality of the curbstone. It also eliminates the need for separate curbstone protection devices, improving construction efficiency and overcoming the shortcomings of traditional vertical curbstone installation.

[0012] This invention employs a specialized mortar spreading tool in the mortar spreading process, which can quickly spread mortar according to the designed inclination angle and thickness, while ensuring the flatness of the mortar.

[0013] This invention employs support tools for inclined support during the curbstone installation process and pre-embeds supporting steel bars within the road side formwork to ensure the consistency and stability of the curbstone's inclination angle, as well as the flatness and straightness of the curbstone.

Detailed Implementation

[0016] 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.

[0017] The curbstone tilting installation device of this embodiment includes two main parts: a mortar spreading tool for leveling the mortar 21 under the curbstone 22 and a support tool for supporting the tilted curbstone 22. The two main parts are described in detail below.

[0018] The mortar spreading tool can shape the mortar 21 below the curbstone 22 to the designed thickness and slope, so that the curbstone 22 achieves the designed slope. The mortar spreading tool includes two parallel trapezoidal baffles 1. The horizontal distance between the two trapezoidal baffles 1 is equal to the horizontal width of the installed inclined curbstone 22, or in other words, the horizontal distance between the two trapezoidal baffles 1 is equal to the horizontal width of the mortar 21 below the curbstone 22. The upper end of the trapezoidal baffles 1 is divided into a horizontal part and an inclined part. A horizontal plate 2 is connected between the upper horizontal parts of the two trapezoidal baffles 1. The horizontal plate 2 is equipped with a handle 3, which is used to pull the mortar spreading tool. A right-angled trapezoidal scraper 4 is connected to the inclined portion at the upper end of the trapezoidal baffle 1. The lower end of the right-angled trapezoidal scraper 4 is a hypotenuse. The vertical distance between the two ends of the hypotenuse and the bottom surface of the mortar spreading tool is equal to the thickness of the left and right ends of the mortar 21 spread below the curbstone 22. The angle between the hypotenuse of the right-angled trapezoidal scraper 4 and the horizontal plane is the same as the inclination angle of the curbstone 22. That is, the mortar 21 can be shaped into a shape where one end is lower than the other by the lower hypotenuse of the right-angled trapezoidal scraper 4. The inclination angle of the shaped mortar 21 is consistent with the designed inclination angle of the curbstone 22, and the thickness of the shaped mortar 21 is consistent with the designed thickness of the spread mortar 21. Preferably, the angle between the hypotenuse of the right-angled trapezoidal scraper 4 and the horizontal plane is between 1° and 3°, that is, the installed curbstone 22 is inclined at 1° to 3°, and a slight inclination is sufficient. To facilitate understanding of the present invention, the tilt angle is enlarged in the accompanying drawings so that the tilt can be clearly seen. After installation, the bottom surface of the curbstone 22 is slightly higher on the side closer to the road and slightly lower on the side farther from the road, and the whole surface is tilted towards the side farther from the road.

[0019] The aforementioned support tool includes a base plate 5 and an inclined support plate 6 hinged together. In this embodiment, the base plate 5 and the inclined support plate 6 are preferably hinged together. A groove 7 along the width of the base plate 5 is provided in the middle of the base plate 5. Several adjusting threaded holes 8 are evenly distributed on the bottom surface of the groove 7. The adjusting threaded holes 8 do not penetrate the base plate 5. A slider 9 is provided within the groove 7, and the slider 9 can slide left and right within the groove 7. Fixed threaded holes 10 corresponding to the adjusting threaded holes 8 are provided at both ends of the slider 9. The slider 9 is fixed together by bolts 11 passing through the fixed threaded holes 10 and the adjusting threaded holes 8. Two fixed plates A12 are symmetrically arranged in the middle of the slider 9, with a horizontal fixed shaft A13 passing between the two fixed plates A12. The fixed shaft A13 has threads at both ends, and the two ends of the fixed shaft A13 located outside the two fixed plates A12 are fixed to the fixed plates A12 by nuts A14. Two fixed plates B15 are symmetrically arranged in the upper middle part of the inclined support plate 6. A horizontal fixed shaft B16 passes between the two fixed plates B15. The fixed shaft B16 has threads at both ends and is fixed to the fixed plates B15 by nuts B17. The upper end of a support rod 18 is rotatably connected to the fixed shaft B16, and the lower end is rotatably connected to the fixed shaft A13. The upper and lower ends of the support rod 18 are respectively provided with round holes, which are passed through the fixed shafts B16 and A13. The support rod 18 can rotate around the fixed shafts B16 and A13.

[0020] This invention also includes a method for inclined installation of curb stones, based on the aforementioned mortar spreading tools and support tools, comprising the following steps: Step 1: First, construct the road side formwork 19. The construction method for the road side formwork 19 is the same as the conventional construction method, and will not be repeated here. The difference in this embodiment is that, during the construction of the road side formwork 19, several supporting steel bars 20 are evenly embedded along the length of the road side formwork 19 on the side away from the curbstone 22. The embedded supporting steel bars 20 are perpendicular to the road side formwork 19. The horizontal distance between the supporting steel bars 20 and the bottom end of the curbstone 22 side closest to the supporting steel bars 20 is exactly equal to the width of the support tool base plate 5. The supporting steel bars 20 are used to block the support tool during later construction and prevent the support tool from sliding horizontally. Preferably, the length of the supporting steel bars 20 protruding upward from the road side formwork 19 is 3-6cm.

[0021] Step Two: First, initially spread mortar 21 on the upper surface of the road side formwork 19 at the location where the curbstone 22 will be installed. Then, use a mortar spreading tool to level the mortar 21. When using the tool, place it on the mortar 21 and pull it using the handle 3. The mortar 21, after being pulled past the tool, is shaped by the right-angled trapezoidal scraper 4, making the side of the mortar 21 furthest from the road lower and the side closer to the road higher, with a trapezoidal longitudinal section. The mortar spreading tool ensures that the shape and inclination of the mortar 21 meet the design requirements, and the thickness is also shaped to the designed thickness. Excess mortar 21 is pushed to the outside or back of the tool and cleaned away. This step uses the mortar spreading tool to ensure that the initially spread mortar 21 achieves the designed inclination angle and thickness.

[0022] Step 3: Rotate the inclined support plate 6, and slide the slider 9 in the groove 7. Adjust the inclination angle of the inclined support plate 6 of the support tool to match the inclination angle of the designed curbstone 22. After adjusting the inclination, fix the slider 9 with bolts 11 so that the slider 9 can no longer slide, so that the upper and lower ends of the support rod 18 can no longer rotate. Then place the support tool on the upper surface of the road side formwork 19, so that the edge of the bottom plate 5 of the support tool abuts against the support steel bar 20.

[0023] Step 4: Place the curbstone 22 at an angle on the mortar 21 prepared in Step 2. The side of the curbstone 22 closest to the supporting steel bar 20 rests against the inclined support plate 6, and the inclined support plate 6 supports the curbstone 22.

[0024] Step 5: Once the mortar 21 has reached its strength, remove the support tools. Then, construct the curb backrest 23 using the conventional method. The supporting steel bars 20 are located inside the curb backrest 23 and are cast integrally with it. At this point, the inclined installation of the curb 22 is complete. The curb 22 installed using the above method is slightly inclined, which prevents the curb 22 on the side closest to the road from being scraped or squeezed by the steel wheels of the road roller during road construction.

[0025] 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.
