Description

Technical Field

[0001] The invention belongs to the field of construction engineering, and in particular relates to a curbstone inclined installation device. Background Art

[0002] Vertical installation of curbstones is a traditional installation method. However, vertically installed curbstones are easily scratched and squeezed by steel wheels during road asphalt paving and rolling, causing the curbstones to be damaged. In view of the disadvantages of vertical installation of curbstones, there are currently many curbstone protection devices. Before road asphalt paving and rolling construction, curbstone protection devices are used to reduce damage to curbstones. However, current curbstone protection devices are generally complex in structure and will also hinder paving and rolling construction, affecting construction efficiency and increasing construction costs. In view of the current problems, it is necessary to study and improve the traditional curbstone installation method. Summary of the invention

[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 curb.

[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 by hinges.

[0008] A method for installing a curbstone obliquely comprises the following steps:

[0009] Step 1: Construction of the road side formwork. When constructing the road side formwork, a number of supporting steel bars are evenly pre-buried along the length direction 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 end of the curb is equal to the width of the base plate.

[0011] Step 3: Adjust the inclination angle of the inclined support plate of the support tool to be consistent with 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 plate edge of the support tool rests on the supporting steel bar;

[0012] Step 4: Install the curbstone, place the curbstone on the mortar in step 2 at an angle, with the side of the curbstone close to the supporting steel bar resting against the inclined support plate;

[0013] Step 5: Once the mortar has reached sufficient strength, remove the support tools and proceed to construct the curb backing.

[0014] As a preferred option:

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0029] The inclined curb installation device of this embodiment includes two major parts: a mortar spreading tool for leveling the mortar 21 under the curb 22 and a supporting tool for supporting the inclined curb 22. The two major parts are described in detail below.

[0030] The mortar spreading tool can arrange the mortar 21 under the curb 22 into a designed thickness and inclination, so that the curb 22 reaches the designed inclination. The mortar spreading tool includes two parallel trapezoidal baffles 1, and the horizontal distance between the two trapezoidal baffles 1 is equal to the horizontal width of the inclined curb 22 after installation, or in other words, the horizontal distance between the two trapezoidal baffles 1 is equal to the horizontal width of the mortar 21 under the curb 22. The upper end of the trapezoidal baffle 1 is divided into a horizontal part and an inclined part, and a horizontal plate 2 is connected between the upper horizontal parts of the two trapezoidal baffles 1, and a handle 3 is provided on the horizontal plate 2, and the mortar spreading tool is pulled by the handle 3. A right-angled trapezoidal scraper 4 is connected between the inclined parts at the upper end of the trapezoidal baffle 1. The lower end of the right-angled trapezoidal scraper 4 is a hypotenuse. The vertical distances between the two ends of the hypotenuse and the bottom surface of the mortar paving tool are respectively equal to the thickness of the left and right ends of the mortar 21 paved below the curb 22. The angle between the hypotenuse of the right-angled trapezoidal scraper 4 and the horizontal plane is consistent with the inclination angle of the curb 22, that is, the mortar 21 can be adjusted to a state where one end is low and the other end is high through the hypotenuse at the lower end of the right-angled trapezoidal scraper 4. The inclination angle of the adjusted mortar 21 is consistent with the designed inclination angle of the curb 22, and the thickness of the adjusted mortar 21 is consistent with the designed thickness of the paved mortar 21. Preferably, the angle between the hypotenuse of the right-angled trapezoidal scraper 4 and the horizontal plane is between 1°-3°, that is, the installed curb 22 is inclined by 1°-3°, and a slight inclination is sufficient. In order to facilitate understanding of the scheme of the present invention, the inclination angle is magnified in the drawings so that the inclination can be clearly seen. The bottom surface of the installed curb 22 is slightly higher on the side close to the road and slightly lower on the side away from the road, and the whole is inclined in the direction away from the road.

[0031] The above-mentioned 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 by hinges. A slide groove 7 is provided in the middle of the base plate 5 along the width direction of the base plate 5. A plurality of adjustment threaded holes 8 are evenly provided on the bottom surface of the slide groove 7. The adjustment threaded holes 8 do not penetrate the base plate 5. A slider 9 is provided in the slide groove 7. The slider 9 can slide left and right in the slide groove 7. Fixed threaded holes 10 corresponding to the adjustment threaded holes 8 are provided at the left and right ends of the slider 9. The slider 9 is fixed together by bolts 11 passing through the fixed threaded holes 10 and the adjustment threaded holes 8. Two fixed plates A12 are symmetrically provided in the middle of the slider 9. A horizontal fixed shaft A13 passes between the two fixed plates A12. Threads are provided at both ends of the fixed shaft A13. The two ends of the fixed shaft A13 are located on the outside of the two fixed plates A12 and are fixed to the fixed plates A12 by nuts A14. Two fixing plates B15 are symmetrically arranged in the middle upper part of the inclined support plate 6, and a horizontal fixing shaft B16 passes through the two fixing plates B15. Similarly, threads are arranged at both ends of the fixing shaft B16, and both ends of the fixing shaft B16 are fixed to the fixing plate B15 by nuts B17. The upper end of a support rod 18 is rotatably connected to the fixing shaft B16, and the lower end is rotatably connected to the fixing shaft A13. The upper and lower ends of the support rod 18 are respectively provided with circular holes, and the upper and lower ends of the support rod 18 are respectively passed through the circular holes on the fixing shaft B16 and the fixing shaft A13, and the support rod 18 can rotate around the fixing shaft B16 and the fixing shaft A13.

[0032] The present invention also includes a method for installing a curbstone in an inclined manner, which is based on the above-mentioned mortar paving tool and support tool and includes the following steps:

[0033] Step 1: First, the road side form 19 is constructed. The construction of the road side form 19 is the same as the conventional construction method, which will not be repeated here. The difference in this embodiment is that when constructing the road side form 19, a plurality of support steel bars 20 are evenly pre-buried along the length direction of the road side form 19 on the side away from the curb 22 in the road side form 19. The pre-buried support steel bars 20 are perpendicular to the road side form 19. The horizontal distance between the support steel bars 20 and the bottom end of the side of the curb 22 close to the support steel bars 20 is just equal to the width of the support tool bottom plate 5. The support steel bars 20 are used to block the support tool in the later construction to prevent the support tool from sliding horizontally. Preferably, the length of the support steel bars 20 exposed upward from the road side form 19 is 3-6 cm.

[0034] Step 2: Preliminarily spread mortar 21 at the position where the curb 22 is installed on the upper surface of the road side mold 19, and then use the mortar spreading tool to level the mortar 21. When using, place the mortar spreading tool on the mortar 21, and then pull the mortar spreading tool through the handle 3. The mortar 21 after being pulled through the mortar spreading tool is shaped by the right-angle trapezoidal scraper 4, so that the mortar 21 is low on the side away from the road and high on the side close to the road, and the longitudinal section is trapezoidal. The mortar spreading tool makes the shape and inclination of the mortar 21 meet the design requirements, and the thickness is also adjusted to the designed thickness by the mortar spreading tool. The excess mortar 21 is pushed to the outside or back of the mortar spreading tool and can be cleaned up. In this step, the mortar spreading tool is used to make the preliminarily spread mortar 21 reach the designed inclination angle and thickness.

[0035] Step 3: Rotate the inclined support plate 6, and the slider 9 slides in the slide groove 7. Adjust the inclination angle of the inclined support plate 6 of the supporting tool to be consistent with the designed inclination angle of the curb 22. After adjusting the inclination, fix the slider 9 with the bolt 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, and then place the supporting tool on the upper surface of the road side mold 19, so that the edge of the bottom plate 5 of the supporting tool rests on the supporting steel bar 20.

[0036] Step 4: Place the curbstone 22 at an angle on the mortar 21 prepared in step 2, with the side of the curbstone 22 close to the supporting steel bar 20 resting on the inclined support plate 6 , and the curbstone 22 is supported by the inclined support plate 6 .

[0037] Step 5: After the mortar 21 reaches the required strength, the supporting tool can be directly removed, and then the curbstone backrest 23 is constructed according to the conventional method. The supporting steel bar 20 is located in the curbstone backrest 23 and cast as one with the curbstone backrest 23. At this point, the inclined installation of the curbstone 22 is completed. The curbstone 22 installed according to the above method is slightly inclined, so that the curbstone 22 close to the road side can be prevented from being scratched or squeezed by the steel wheel of the roller during road construction.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
