Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular, to a dual-purpose tool for roughening and grooving concrete pavements. Background Technology

[0002] In modern transportation infrastructure construction, concrete pavement is widely used due to its excellent load-bearing capacity and durability. After pouring, concrete roads generally have a smooth surface. However, for some concrete roads with special requirements, such as airport runways, there are specific requirements for the coefficient of friction and texture. In road and municipal engineering projects, it is often necessary to roughen the concrete pavement or leveling layer to improve its friction, and to cut joints in the concrete slabs to prevent cracking caused by shrinkage and creep.

[0003] Surface roughening of concrete is an important technical measure to increase the adhesion and anti-slip function of concrete surfaces. It is typically done manually with a trowel and reinforcing bars before the concrete initially sets, or using a concrete roughening machine after the concrete has hardened. Current methods involve manual roughening, which is inefficient, results in uneven roughening, and inconsistent roughening depth. Alternatively, using a roughening machine requires the concrete to reach a certain strength, and the equipment is expensive, requires a large working surface, is unsuitable for confined spaces, and generates significant dust, increasing occupational health risks for workers and contributing to dust and noise pollution.

[0004] Joint cutting in concrete slabs is typically performed when the concrete reaches approximately 50% of its design strength. Cutting too early can result in incomplete release of internal stress, while cutting too late may lead to surface cracking. The cut depth is usually 6-10 cm, and the spacing is determined based on the length of the concrete slab and local climate conditions, typically around 6 meters. Currently, cutting machines or joint cutting machines are commonly used for concrete slab jointing. However, using cutting machines has drawbacks such as high equipment costs, high mechanical consumption, insufficient cut width, and a tendency to induce concrete cracking. Furthermore, cutting machines can easily damage the edges and corners of the concrete.

[0005] In actual construction, the roughening and grooving processes usually require separate equipment to be used sequentially. For example, patent 201320788576.X discloses a concrete pavement roughening tool that can only perform roughening and does not have a grooving function. This not only increases the investment cost of construction equipment but also leads to a cumbersome construction process, low construction efficiency, and extended construction period. Furthermore, existing roughening machines, cutting machines, and other equipment are not flexible and convenient to operate, making it difficult to adapt to changes in different construction environments and requirements. Therefore, there is a need to provide a tool that can perform both roughening and grooving to reduce equipment costs. Utility Model Content

The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, but the present utility model can be implemented in many different ways as defined and covered below.

[0027] An embodiment of the first aspect of this utility model provides a dual-purpose tool for roughening and grooving concrete pavements, including a pulling component 10, a roughening component 20, and a grooving component 30. The pulling component 10 is connected to the roughening component 20 and is used to drive the roughening component 20 to perform roughening construction on the concrete pavement to form a rough texture. The grooving component 30 is detachably installed below the roughening component 20 and is used to perform grooving construction on the concrete pavement to form a groove.

[0028] The pulling component 10 is fixedly connected to the texturing component 20, such as by welding or screw connection. The pulling component 10 is used to drive the texturing component 20 and the grooving component 30 to move, so as to perform texturing and grooving construction on the concrete pavement. The texturing component 20 includes rows of texturing steel wires, with a spacing between each row of texturing steel wires, so as to form a texturing with uniform spacing and depth during construction. The texturing component 20 can also use existing wire brushes, which have built-in fiber cloth, and the wire brush can be fixed below the pulling component 10 by attaching the fiber cloth. The grooving component 30 is detachably installed below the texturing component (20) and is used to perform grooving construction on the concrete pavement to form grooves. In this application, the texturing component 20 and the grooving component 30 are set to a detachable connection method to facilitate the separate texturing and grooving construction without affecting each other, thereby improving the construction quality.

[0029] This utility model discloses a dual-purpose tool for roughening and grooving, comprising a roughening component 20 and a grooving component 30. The roughening component 20 is driven by a pulling component 10 and is used for roughening concrete pavements. The pulling component 10 facilitates manual operation, making the tool flexible and suitable for pavements of various widths, thus ensuring construction quality. The grooving component 30 is detachably installed below the roughening component 20 via a connecting part 31. During roughening, the grooving component 30 can be easily removed from the roughening component 20. During grooving, the grooving component 30 is installed on the roughening component 20 via the connecting part 31, thereby achieving the dual-purpose effect of roughening and grooving, saving equipment costs. This utility model also has the advantages of convenient construction, reusability, and enhanced practicality.

[0030] In an embodiment of this utility model, the grooving assembly 30 includes a connecting portion 31 and a grooving portion 32. The grooving portion 32 is disposed at the bottom of the connecting portion 31, and the connecting portion 31 is used for detachable connection with the roughening assembly. The grooving portion 32 is 4-6mm wide and 60-70mm deep. The grooving portion 32 can be made of hard alloy material, which has extremely high hardness and wear resistance, and can press out clear and regular grooves on concrete pavement. The shape of the grooving portion 32 is cuboid or cylindrical, and its specific shape is selected according to actual construction needs and grooving effect. For example, a cuboid-shaped grooving portion 32 can press out rectangular grooves, which is suitable for pavement requiring strong drainage capacity; a cylindrical grooving portion 32 can press out circular grooves, which is suitable for pavement with high noise reduction requirements.

[0031] In an embodiment of this utility model, the connecting part 31 includes a base plate 33 and a side plate 34. The base plate 33 and the side plate 34 are connected to form a mounting groove, which is used to snap onto the mounting plate 21. The mounting groove is a U-shaped groove, through which the pressing groove assembly 30 can be directly snapped onto the mounting plate 21 for a secure connection. Both the base plate 33 and the side plate 34 are made of high-strength metal materials, such as steel or stainless steel, to ensure the strength and stability of the connecting part 31. The width and length of the base plate 33 are designed according to the dimensions of the pressing groove 32 and the mounting plate 21. Generally, the width of the base plate 33 is wider than the width of the pressing groove 32, and the length matches the length of the mounting plate 21. The height of the side plate 34 is designed according to the thickness of the mounting plate 21 and the wire brush. At the connection between the base plate 33 and the side plate 34, welding or bolting can be used for fixing to ensure the structural strength of the connecting part 31.

[0032] In an embodiment of this utility model, the connecting part 31 further includes a limiting plate 35, which is connected to the bottom plate 33 and the side plate 34, forming a groove structure with an opening on one side. This prevents the grooving assembly 30 from detaching from the roughening assembly 20 during construction. The function of the limiting plate 35 is to limit the grooving assembly 30 when it is installed below the roughening assembly 20, ensuring that the grooving assembly 30 does not loosen or fall off during construction. The shape and size of the limiting plate 35 are designed according to the structure of the connecting part 31 and the shape of the mounting plate 21. Generally, the length of the limiting plate 35 matches the length of the side plate 34. The limiting plate 35 can be fixed to the bottom plate 33 and the side plate 34 by welding. The limiting plate 35 is installed on the front side of the bottom plate 33, and its two ends are connected to the side plate 34 respectively. During grooving construction, the limiting plate 35 prevents the grooving part 32 from detaching from the roughening assembly 20 due to the resistance of the concrete.

[0033] In an embodiment of this utility model, the mounting plate 21 is provided with a snap-fit ​​groove, and the side plate 34 is provided with a snap-fit ​​part 36 for cooperating with the snap-fit ​​groove on the mounting plate 21. The snap-fit ​​groove and the snap-fit ​​part 36 are designed to further enhance the connection between the pressing assembly 30 and the roughening assembly 20. The shape and size of the snap-fit ​​groove are adapted to the shape and size of the snap-fit ​​part 36. The snap-fit ​​part 36 can be in the form of a protrusion or a hook, cooperating with the snap-fit ​​groove to achieve a quick and secure connection between the pressing assembly 30 and the roughening assembly 20. In practical applications, to facilitate the installation and disassembly of the pressing assembly 30, the surfaces of the snap-fit ​​groove and the snap-fit ​​part 36 can be smoothed to reduce friction.

[0034] In an embodiment of this utility model, the texturing assembly 20 includes a mounting plate 21 and a texturing section 22. The texturing section 22 is disposed at the bottom of the mounting plate 21, and the mounting plate 21 is used to connect with the traction assembly 10. The mounting plate 21 is the basic load-bearing component of the texturing assembly 20, used to connect with the traction assembly 10, and provides installation support for the texturing section 22. The mounting plate 21 is made of high-strength metal material, such as aluminum alloy or steel plate, and has sufficient strength and rigidity to withstand the forces during the texturing process. The mounting plate 21 is rectangular in shape, and its dimensions are designed according to actual construction needs, generally with a length of 50-100mm and a width of 50-100mm, but larger dimensions are also possible. A structure for connecting to the traction assembly 10 is provided at the top of the mounting plate 21. This structure can be a bolt connection hole, a snap-fit ​​groove, or other suitable connection method to ensure a firm connection between the mounting plate 21 and the traction assembly 10. A wire brush is disposed at the bottom of the mounting plate 21 for texturing construction.

[0035] In an embodiment of this utility model, the roughening section 22 includes several groups of roughening steel wires spaced apart, with a spacing of 1-30 mm between the groups. Each roughening steel wire group consists of multiple steel wires with a diameter of 0.1-2 mm. These wires possess high hardness and wear resistance, effectively roughening the concrete pavement. To further improve the service life and roughening effect of the roughening section 22, the surface of the steel wires can be treated with rust prevention, such as galvanizing or nickel plating. The spacing between the roughening steel wire groups can be adjusted according to the specific conditions of the concrete pavement and the roughening requirements. For example, for concrete pavements with high surface hardness, the spacing between the roughening steel wire groups can be appropriately reduced to increase the roughening strength; for concrete pavements with low surface hardness, the spacing can be appropriately increased to improve the roughening efficiency. The steel wires in the roughening steel wire groups can be connected to the mounting plate 21 by welding, threaded connection, or insertion.

[0036] In an embodiment of this utility model, the roughening part 22 further includes an adhesive part 23, through which the roughening steel wire assembly is connected to the bottom of the mounting plate 21. The adhesive part 23 includes adhesive fiber cloth, which ensures a firm connection between the roughening steel wire assembly and the mounting plate 21. In practical applications, to enhance the adhesive effect, surface treatments such as grinding and cleaning can be performed on the bottom of the mounting plate 21 and the connection part 31 of the roughening steel wire assembly to remove surface oil, dust, and other impurities, thereby improving the adhesion of the adhesive fiber cloth. Furthermore, to facilitate the replacement of worn roughening steel wire assemblies, the adhesive part 23 can be designed as a detachable structure, for example, in the form of an adhesive sheet or adhesive strip. When the roughening steel wire assembly is severely worn, it can be easily peeled off and replaced with a new steel wire brush.

[0037] In an embodiment of this utility model, the pulling assembly 10 includes a pulling rod 11 and a connecting rod 12. The first end of the connecting rod 12 is provided with a connector for connecting to the texturing assembly 20, and the second end of the connecting rod 12 is movably connected to the pulling rod 11. The pulling rod 11 is a key component of the tools used by construction workers, made of high-strength metal materials such as aluminum alloy or steel. Its length is designed according to actual construction needs, generally 0.5-1.5m. The surface of the pulling rod 11 can be treated with anti-slip material, such as by setting anti-slip textures or wrapping it with anti-slip material, to improve the comfort and safety of the workers' grip. The connecting rod 12 is used to connect the pulling rod 11 and the texturing assembly 20. The connector at its first end can be a bolt head, a snap-fit ​​connector, or other suitable connection method to ensure a secure connection between the connecting rod 12 and the mounting plate 21 of the texturing assembly 20. The second end of the connecting rod 12 is connected to the tie rod 11 via a movable connection. This movable connection can be in the form of a rotary joint or a hinge, allowing the tie rod 11 to rotate flexibly during operation to adapt to different construction angles and directions. For example, when construction workers need to roughen or groove the edge of the road surface, they can rotate the tie rod 11 to allow the roughening component 20 or the grooving component 30 to accurately reach the construction position.

[0038] In an embodiment of this utility model, the second end of the connecting rod 12 is provided with a connecting sleeve 13, and the pulling rod 11 is connected to the connecting sleeve 13 by a pin. The connecting rod 12 and the connecting sleeve 13 are welded or threaded together, and the connection between the pulling rod 11 and the connecting sleeve 13 by the pin allows for flexible rotation of the pulling rod 11.

[0039] During the roughening process: Workers hold the pull rod and move the roughening assembly to the concrete pavement area to be roughened. By manipulating the pull rod, the roughening assembly moves across the concrete pavement, and the roughening wire assembly roughens the surface. This process is repeated 2-3 times to create a uniform rough texture on the concrete pavement surface. Testing shows that the surface roughness meets the anti-skid performance requirements.

[0040] During grooving construction: After the roughening process is completed, install the grooving assembly below the roughening assembly. Insert the mounting plate into the mounting slot of the connector, ensuring the locking part and locking slot mate securely, thus guaranteeing a firm installation of the grooving assembly. Operate the pull rod again to move the grooving assembly on the concrete pavement, allowing the grooving part to groove the pavement. After grooving is completed, inspection shows that the width, depth, and flatness of the grooves formed by the grooving part meet relevant standard requirements.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
