Description

Technical Field

[0001] The utility model relates to the technical field of construction, and more specifically, the utility model is a simple grooving tool for concrete road surfaces. Background Art

[0002] With the growth of highway traffic volume and the increase in vehicle speed, the anti-slip performance of concrete road surfaces has become an urgent problem to be solved. To enhance the friction of cement concrete road surfaces, grooving treatment technology is generally adopted. This technology aims to optimize the surface performance of the road surface, significantly improve its anti-slip ability, and increase the friction coefficient. In addition, grooving treatment can effectively prevent the continuous increase in water film pressure caused by the high-speed rotation of vehicle wheels on rainy days, thereby avoiding the occurrence of hydroplaning. By enhancing the adhesion friction resistance between the tire and the road surface, the phenomenon of fog splashing can be reduced, the braking distance of the vehicle can be shortened, the vehicle handling performance can be optimized, and thus the traffic accident rate can be significantly reduced.

[0003] Chinese Utility Model Patent CN205975321U discloses a simple tool for deep grooving of concrete roads. The tool consists of multiple longitudinally arranged angle steels, with transverse angle steels perpendicularly welded at both ends, and overlapping steel bars welded on the upper surface of the longitudinal angle steels. During the grooving operation, workers need to hold the overlapping steel bars and press the entire tool onto the cured concrete road surface to complete the grooving operation. Although this tool can achieve the grooving function, due to its all-steel structure, it has a large self-weight, increasing the labor intensity of workers. Workers need to frequently lift and press the tool, which not only consumes a large amount of physical strength but also is inconvenient to operate. In addition, limited by the weight, the size of the tool cannot be too large, otherwise it will seriously affect the operation convenience of workers, thus restricting its application in the construction of wide road surfaces. Moreover, each operation of this tool can only cover a small area of the road surface, greatly reducing the construction efficiency. At the same time, frequent bending operations also pose a certain threat to the physical health of workers. Summary of the Utility Model

[0004] To solve the technical problem of low efficiency of existing concrete grooving, the utility model innovatively provides a simple grooving tool for concrete road surfaces, which can optimize the traditional road surface grooving process into a grooving process. By holding the simple tool by workers and performing grooving operations from one side of the road surface to the other side, the road surface grooving can be achieved. This design not only improves the operation convenience but also significantly reduces the labor intensity of workers, thereby greatly improving the construction efficiency.

[0020] The following will explain and illustrate in detail a simple concrete road surface grooving tool of the present utility model with reference to the accompanying drawings of the specification.

[0021] As Figures 1-3As shown in the figure, the utility model discloses a simple grooving tool for concrete pavement, which includes a mounting member 1, a grooving member 2, a fixing member 3 and a holding member 4. The mounting member 1 is configured as a plate-like structure, which is not only durable but also easy to install and fix. The mounting member 1 can ensure that each grooving member 2 maintains a stable posture during the operation, thus ensuring the accuracy and uniformity of grooving. The grooving member 2 is the most critical part of the whole tool. They are set as slender columnar structures, numerous and arranged in a straight line. They are inserted into the mounting member 1 at equal intervals through the fixing member 3, and the free ends of the grooving members 2 extend in the first direction starting from the mounting member 1. These grooving members 2 are like sharp blades and can easily cut out neat grooves on the concrete pavement. Compared with the traditional grooving method, the grooving operation is more flexible and efficient, which can significantly improve the construction speed and quality. With the assistance of the fixing member 3, the grooving members 2 are firmly locked in the mounting member 1, ensuring the stability and reliability of the grooving members 2 during the operation. This stable structural design not only extends the service life of the tool but also reduces the safety risks caused by component loosening. The holding member 4 is fixed to the mounting member 1 through a connecting member 5. The free end of the holding member 4 extends in the second direction starting from the mounting member 1, forming a sharp contrast with the first direction of the grooving member 2. The first direction and the second direction can be set as opposite directions or there is a certain included angle between them. This design enables the worker to easily hold and control the direction and force of the tool during the operation. The holding member 4 adopts the design principle of ergonomics to achieve precise grooving.

[0022] In practical applications, this simple grooving tool for concrete pavement can significantly improve the construction efficiency. The worker only needs to hold the tool and stand on one side of the pavement and perform the grooving operation along the predetermined track to the other side. The whole process is smooth and efficient, which not only reduces the physical burden of the worker but also greatly improves the construction speed and quality. Compared with the traditional grooving method, using this grooving tool can save about 30% of the construction time and significantly improve the uniformity and aesthetics of the pavement grooves. In addition, this grooving tool also has wide applicability and flexibility. It can not only be used for the grooving operation of concrete pavement, but also be appropriately modified and adjusted according to actual needs to meet the construction requirements of different materials and specifications of pavement or the construction requirements of step surfaces.

[0023] As Figure 4As shown, in an embodiment of the present utility model, one end of the grooving member 2 is set as a rectangular end. The rectangular end not only perfectly matches the rectangular jack 11 on the mounting member 1, effectively preventing the rotation and deviation of the grooving member 2 during the installation process, but also greatly improves the connection stability. At the same time, the design of the rectangular end also facilitates the quick positioning and installation by workers, improving the construction efficiency. An installation hole 21 is particularly provided in the middle of the rectangular end of the grooving member 2. The mounting member 1 is not only provided with the jack 11 matching the rectangular end of the grooving member 2, but also provided with a fixing hole 12 penetrating through the jack 11. The cross-sectional shapes of the fixing hole 12 and the jack 11 are in a cross shape. After the grooving member 2 is inserted into the rectangular jack 11 of the mounting member 1, the installation hole 21 is aligned with the fixing hole 12. This unique shape design not only enhances the connection strength, but also enables the fixing member 3 to more accurately lock the grooving member 2, preventing it from loosening or falling off during the working process. To further optimize the connection effect, the fixing member 3 is selected as a fixing bolt. This choice is based on the wide application of fixing bolts in mechanical connections and their excellent fastening performance. The fixing hole 12 of the mounting member 1 is designed as a threaded hole so that the fixing bolt can be directly screwed into it to achieve a quick and firm connection. This connection method is not only simple and convenient to operate, but also facilitates the replacement or maintenance of the grooving member 2 when needed, greatly reducing the cost and time of tool maintenance. It is worth mentioning that the design of the grooving member 2 also fully considers the actual use requirements. From the rectangular end to the free end, the grooving member 2 gradually becomes thinner. This shape design not only conforms to the principle of ergonomics, reducing the burden on workers during operation, but also enables the grooving member 2 to operate more flexibly and accurately during the road grooving operation. At the same time, the gradually thinning design also improves the adaptability of the grooving member 2 under complex road conditions, ensuring the stability and reliability of the construction quality. This connection method between the grooving member 2 and the mounting member 1 shows excellent performance. In multiple road construction projects, this connection method not only significantly improves the construction efficiency and quality, but also greatly reduces the failure rate and maintenance cost of tools.

[0024] In an embodiment of the present utility model, the specific installation process of the holding member 4 is as follows: The connecting member 5 is composed of a support member 51 and a sleeve member 52. The support member 51 is in a plate shape, and its back is fixedly connected to the mounting member 1 closely. The sleeve member 52 is designed in a cylindrical shape, and one end of it is firmly fixed at the exact center of the support member 51, while the holding member 4 is skillfully inserted inside the sleeve member 52. In terms of the connection method, the support member 51 is stably combined with the mounting member 1 through bolt connection to ensure the stability of the structure. To further optimize the fixing effect of the holding member 4, the sleeve member 52 is carefully designed into two parts: an equal-diameter section and a variable-diameter section, and these two parts are integrally formed. The unique feature of the variable-diameter section is that its cross-sectional area gradually decreases along the direction from the equal-diameter section to the support member 51, forming a clever gradient structure. At the same time, the holding member 4 is also correspondingly designed and adjusted. It is provided with a variable-diameter end that perfectly matches the inner wall of the variable-diameter section. This design not only improves the stability of the holding member 4 but also makes the overall structure more compact.

[0025] In an embodiment of the present utility model, the mounting member 1 can be made of epoxy resin fiber board, the grooving member 2 can be made of plastic welding rod, the fixing member 3 uses hexagon bolts, and the distance between adjacent grooving members 2 is 12 mm - 25 mm, and this distance can be adjusted according to the actual situation. The holding member 4 is made of wood material to reduce the overall weight of the tool.

[0026] Taking road construction as an example, the working principle of the present utility model is as follows:

[0027] Implementation preparation: Select materials such as plastic welding rods, hexagon bolts, epoxy resin fiber boards, and wooden handles of fixed specifications and models to enter the site. Process them according to the above embodiments. After assembly, they can be put into use, making full preparations for on-site installation.

[0028] On-site implementation:

[0029] The first step: On-site concrete paving and vibrating

[0030] When discharging materials during cloth laying, the discharging should be uniform, and the cloth laying should be adapted to the paving speed. For the mixture with a slump of 10 - 40 mm, its loose paving coefficient is 1.12 - 1.25. During paving, workers hold shovels in their hands to fill the unfilled positions. On longitudinal slope sections, it is advisable to pave in the uphill direction.

[0031] When the fabric length is greater than 10m, the vibration operation can be started. The vibration is carried out by using an internal vibrator in combination with a screed. When vibrating with the vibrator, the moving distance each time should not exceed 1.5 times the effective action radius of the vibrator and shall not be greater than 50cm; the vibration time should be 15 - 30s. When compacting, it should be carried out evenly, slowly and continuously without interruption, and the operation speed should be determined according to the operation effect (taking that no coarse aggregate is exposed on the surface of the mixture, no bubbles emerge from the liquefied surface and cement slurry overflows as the standard). And strengthen the vibration of the parts that are not easy to be compacted, such as the positions close to the formwork and steel bars.

[0032] Step 2: Concrete leveling

[0033] After the concrete is compacted by the vibrator, the slurry extraction and leveling should be immediately carried out with a three-roller shaft. When the three-roller shaft is used for rolling and leveling, there should be a special person to handle the height of the material level in front of the shaft. The height difference of the material level compacted by the three-roller shaft rolling should be 5 - 20mm higher than the top surface of the formwork. When it is too high, it should be supplemented by manual removal; when there is a gap under the shaft, concrete should be used for patching. After the three-roller shaft leveling, the surface should be accurately leveled by using a transverse and full-length aluminum alloy screed to move back and forth 2 - 3 times, so that the flatness of the concrete surface meets the requirements, and then the edges are cleared and the joints are formed, the sticky slurry is removed, and the missing edges and corners are repaired. After the concrete is leveled with a straightedge, after the surface water seepage is completed, fine leveling should be carried out in time to ensure the flatness of the road surface.

[0034] Step 3: Concrete grooving

[0035] After the concrete pavement is leveled and when it starts to set, the concrete pavement grooving treatment is carried out. The worker holds a simple tool and grooves from one side of the road surface to the other side. When using the grooving tool, it should be stable and uniform to avoid problems such as uneven gap spacing, bending, fracture, etc., and ensure the groove width, groove depth and straightness to ensure the beauty of the completed pavement.

[0036] Step 4: Concrete pavement maintenance

[0037] Generally, 2h after the concrete pavement is grooved and when the surface has a certain strength, it should be immediately covered with geotextile for moisture conservation. Generally, the number of days for moisture conservation should be 14 - 21d. In high-temperature weather, it should not be less than 14d, and in low-temperature weather, it should not be less than 21d. During the maintenance period, vehicles and personnel are prohibited from walking on it.
