Description

Technical Field

[0001] The utility model relates to the technical field of concrete floor construction, in particular to a dual-purpose tool for finishing and grooving concrete floors. Background Art

[0002] Finishing a concrete pavement improves surface smoothness and wear resistance, enhancing its aesthetics. Grooving helps prevent cracking and improves driving grip, ensuring safety. This treatment extends the pavement's lifespan and enhances the driving experience.

[0003] A search revealed a utility model with publication number CN219157335U, which provides a device for embossing concrete pavement surfaces. The device comprises a rectangular pressing plate, a connecting plate, and a push-pull handle. The bottom surface of the pressing plate is provided with a groove along its longitudinal centerline, within which multiple embossing components are equidistantly spaced longitudinally. Each embossing component comprises an embossing rod, two limit plates, and a spring. The front end of the embossing rod is rotatably connected to the two limit plates, the tops of which are fixedly embedded within the pressing plate. One end of the spring is welded to the center of the embossing rod, and the other end is connected to the pressing plate via a screw. The connecting plate is positioned on its top surface along its transverse centerline, and the push-pull handle is connected to the connecting plate via a ball joint. This utility model can simultaneously perform both embossing and finishing on a pavement surface, resulting in high construction efficiency.

[0004] When the device is in use, the pressing plate is pushed forward, and the pressing plate can be used to finish the concrete surface. When the pressing plate is pulled backward, the embossing rod will be inserted into the concrete surface. As the pressing plate is pulled backward, the embossing rod can carve grooves of a certain depth on the concrete surface. This design means that when finishing the concrete surface, construction workers can only push the pressing plate forward. However, in the actual finishing operation process, construction workers are often required to pull and push the pressing plate back and forth to achieve the ideal finishing effect, resulting in large limitations in the use of this device. In addition, the depth of the embossing rod inserted into the concrete surface is fixed and cannot be flexibly adjusted according to different construction needs and the actual conditions of the concrete surface, further reducing the applicability of the device.

[0029] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] See also Figure 1-9The utility model provides a dual-purpose tool for finishing and grooving concrete floors, comprising a trowel plate 1 and a hollow long rod 2. The upper surface of the trowel plate 1 is fixedly connected to a square connecting plate 11. The upper surface of the square connecting plate 11 is fixed to a fixing plate 12 by bolts. The upper surface of the fixing plate 12 is fixedly connected to a fixing seat 13 on both sides. The lower end of the hollow long rod 2 is fixedly connected to a connecting seat 21. The lower surface of the connecting seat 21 is fixedly connected to an outer ear plate 22 on both sides. The outer ear plate 22 is rotatably connected to the fixing seat 13 and is fixed by bolts. The lower surface of the connecting seat 21 is fixedly connected to the outer ear plate 22. The inner ear plate 23 is fixedly connected to the surface and located between the two groups of outer ear plates 22. The left and right sides of the inner ear plate 23 are rotatably connected to the right-angle connecting frame 3. The short side of the right-angle connecting frame 3 is fixedly connected to the right-angle seat 5. The interior of the hollow long rod 2 is connected with a lifting component 4 for adjusting the position of the right-angle seat 5. The front side of the right-angle seat 5 is slidably connected to a C-shaped fixed frame 6. The rear side of the C-shaped fixed frame 6 is connected with an adjusting component 7 for changing the height of the C-shaped fixed frame 6. The interior of the C-shaped fixed frame 6 is fixedly connected to a fixing frame 8, and the interior of the fixing frame 8 is detachably connected to several groups of grooving blocks 9.

[0031] When finishing a concrete pavement, the utility model can lift the right-angle seat 5 via the lifting assembly 4, thereby moving the groove block 9 away from the concrete pavement. Construction workers can then use the hollow long rod 2 to drive the trowel plate 1 back and forth, completing the finishing operation. When finishing is complete and grooves need to be drawn, the lifting assembly 4 can be used to lower the right-angle seat 5. The groove block 9 can then be inserted into the concrete pavement. Construction workers then pull the hollow long rod 2 to move the groove block 9, thereby drawing grooves on the concrete pavement. This dual-purpose finishing and groove drawing tool allows finishing and groove drawing to be performed simultaneously, making construction more efficient.

[0032] The present invention allows for flexible adjustment of the height of the C-shaped fixing frame 6 through the adjustment assembly 7, thereby indirectly varying the depth to which the groove block 9 is inserted into the concrete pavement. This design allows the height of the groove block 9 to be precisely adjusted to suit varying construction requirements and the actual conditions of the concrete surface. Whether shallow or deep grooves are required, construction personnel can quickly adjust the height, thereby improving the device's applicability and flexibility and further enhancing overall construction efficiency and quality.

[0033] Specifically, construction workers can flexibly adjust the inclination angle of the hollow long rod 2 and the trowel plate 1 according to their own situation to adapt to different construction environments and needs. The adjustment method is as follows: First, the construction worker needs to loosen the bolts between the fixed outer ear plate 22 and the fixed seat 13 to release the locked state. Then, according to the required inclination angle, appropriately adjust the angle between the hollow long rod 2 and the trowel plate 1. After the adjustment is completed, tighten the bolts to ensure stability in subsequent operations to avoid affecting the construction quality due to angle changes. Through this simple and effective adjustment method, construction workers can better control the troweling effect, improve work efficiency, and ensure that the concrete surface achieves the ideal flatness and smoothness.

[0034] Furthermore, the lifting assembly 4 includes a pull rod 41, which is rotatably connected to the inner side of the right angles of the two sets of right-angle connecting frames 3. The end of the pull rod 41 away from the right-angle connecting frame 3 is rotatably connected to a C-shaped buckle 42, and the side of the C-shaped buckle 42 away from the pull rod 41 is fixedly connected to a moving block 43, and the side of the moving block 43 away from the C-shaped buckle 42 is fixedly connected to a cylindrical seat 44, and the cylindrical seat 44 is slidably connected to the inside of the hollow long rod 2. The surface of the hollow long rod 2 is penetrated by a through groove 24 that provides a sliding position for the moving block 43. The side of the cylindrical seat 44 away from the connecting seat 21 is rotatably connected to an inner rod 45 through a shaft 441. The inner rod 45 is threadedly connected to the inside of the hollow long rod 2, and the end of the inner rod 45 away from the shaft 441 is fixedly connected to a knob 451.

[0035] Specifically, to lift the right-angle seat 5, simply rotate knob 1 451, which drives the inner rod 45 to rotate within the hollow long rod 2. Because the inner rod 45 and the hollow long rod 2 are threaded together, the length of the inner rod 45 extending from the hollow long rod 2 gradually increases as the inner rod 45 rotates. Simultaneously, the inner rod 45 drives the cylindrical seat 44 to slide within the hollow long rod 2 via the shaft 441, and pulls the pull rod 41 via the moving block 43 and the C-shaped buckle 42. This changes the angle between the right-angle connecting frame 3 and the inner ear plate 23, thereby lifting the right-angle seat 5. To lower the right-angle seat 5, simply rotate knob 1 451 in the opposite direction, making the operation simple and convenient.

[0036] Furthermore, two groups of guide grooves 51 are provided on the upper surface of the vertical side of the right-angle seat 5, and the adjustment component 7 includes two groups of guide blocks 71, which are respectively fixedly connected to the left and right ends of the rear side of the C-shaped fixed frame 6, and the two groups of guide blocks 71 are respectively slidably connected to the inside of the two groups of guide grooves 51, and the rear sides of the two groups of guide blocks 71 are fixedly connected with movable blocks 72. The upper surface of the horizontal side of the right-angle seat 5 is rotatably connected with two groups of threaded rods 73, and the two groups of movable blocks 72 are respectively threadedly sleeved on the outside of the two groups of threaded rods 73, and the upper ends of the threaded rods 73 are fixedly connected with knob 2 731.

[0037] Specifically, to change the groove depth, simply adjust the relative height of the C-shaped fixing frame 6 and the right-angle seat 5. The specific adjustment method is: synchronously rotate the two sets of knobs 731. Knob 731 drives the threaded rod 73 to rotate, and the movable block 72 is displaced outside the threaded rod 73. The movable block 72 drives the C-shaped fixing frame 6 through the guide block 71. The guide groove 51 limits and guides the guide block 71, making the movement of the C-shaped fixing frame 6 more stable. This design allows construction personnel to quickly and accurately set the groove depth to meet different construction requirements.

[0038] Furthermore, a C-shaped movable frame 61 is fixed to the front side of the C-shaped fixed frame 6 by screws.

[0039] Specifically, the C-shaped movable frame 61 primarily functions to position the slot blocks 9, ensuring they remain securely within the fixed frame 8 and preventing them from shifting or falling out during use. If a damaged slot block 9 requires replacement, the process is extremely simple. Construction personnel simply remove the C-shaped movable frame 61 from the front of the C-shaped fixed frame 6 to easily remove and replace the damaged slot block 9.

[0040] Furthermore, sliding grooves 52 are provided on the upper surface of the vertical side of the right-angle seat 5 and on the left and right sides of the guide groove 51. Four groups of bases 62 are fixedly connected to the rear side of the C-shaped fixed frame 6. The four groups of bases 62 are respectively located on the left and right sides of the two groups of guide blocks 71. Both sides of the four groups of bases 62 are rotatably connected to rollers 63, and the rollers 63 are slidably connected to the inside of the sliding grooves 52 at the corresponding positions.

[0041] Specifically, when adjusting the position of the C-shaped fixing frame 6 , the C-shaped fixing frame 6 drives the roller 63 to slide inside the sliding groove 52 through the base 62 , making the adjustment process smoother.

[0042] Furthermore, several groups of fixing grooves 81 for installing the grooving blocks 9 are provided inside the fixing frame 8, and limiting grooves 82 are provided on the left and right sides of the fixing grooves 81. The left and right sides of the grooving block 9 are fixedly connected to the limiting blocks 91, and the limiting blocks 91 are movably inserted into the limiting grooves 82 at the corresponding positions.

[0043] Specifically, when installing the groove block 9, it is only necessary to align the limit block 91 with the limit slot 82 and insert it. This design not only simplifies the installation process, but also ensures the accurate positioning of the groove block 9, avoiding loosening or displacement problems caused by improper installation.

[0044] Furthermore, a placement seat 14 for limiting the position of the right-angle connecting frame 3 is fixedly connected to the upper surface of the square connecting plate 11 and located in front of the fixing plate 12. The upper surface of the placement seat 14 is provided with a square notch groove 141 for placing the right-angle connecting frame 3.

[0045] Specifically, when groove drawing is required, the right-angle seat 5 is lowered by the lifting assembly 4. When the right-angle connecting frame 3 is exactly placed in the square notch 141, it indicates that the right-angle seat 5 is correctly positioned. The design of the placement seat 14 ensures that the adjusted right-angle seat 14 always remains parallel to the trowel plate 1. This indirectly ensures that the groove drawing block 9 and the trowel plate 1 are in a perpendicular position, thereby improving the accuracy of the construction.

[0046] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
