Description

Technical Field

[0001] The utility model belongs to the field of concrete road paving, in particular to a road concrete paving tool. Background Art

[0002] When concrete is paved on the road, the road surface is uneven. At the same time, since bubbles are generated in the concrete during the paving process, a vibrating paving tool should be used to drive out the bubbles in the concrete after the concrete road surface is paved. At the same time, the concrete floor should be scraped flat to enhance the density of the concrete and ensure the flatness of the road surface.

[0003] The existing vibrating paving tool for concrete pavement consists of a vibrator and a paving element. The vibrator is installed on the paving element. When the vibrator is manually pulled forward, the concrete is vibrated to discharge the bubbles in the concrete, improve its compactness, and then the paving element flattens the concrete. In order to improve the concrete vibration and exhaust effect, manual repeated operations are required, that is, the concrete pavement must be repeatedly vibrated and flattened, resulting in reduced construction efficiency.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] like Figure 1 , Figure 2As shown, a road concrete paving tool includes a paving element 1, a roller 5 and a vibrator 3, wherein the paving element 1 is an angle steel structure, placed in an "L" state, at this time, one of the two sides constituting the angle steel is in a horizontal state and is called a horizontal side 11, and the other side is in a vertical state and is called a vertical side 12. A fixing plate 2 is provided in the middle of the top of the vertical side 12, and the fixing plate 2 is provided with a connecting hole for installing the vibrator 3. The vibrator 3 is installed on the fixing plate 2, and its handle faces the side of the vertical side 12 away from the horizontal side 11. For the convenience of explanation, the side of the vertical side plate 12 corresponding to the horizontal side 11 is called the rear side, and the side away from the horizontal side 11 is called the front side. The principle of the vibrator 3 and its installation structure are both existing technologies and are not explained here. A connecting ear 4 is provided at each end of the front side of the vertical side 12, and the roller 5 is rotatably installed between the two connecting ears 4. At this time, the length directions of the roller 5 and the angle steel correspond to each other, and a plurality of protrusions 6 are evenly arranged on the circumferential surface of the roller 5. The end of the protrusion 6 at the lowest end of the circumferential surface of the roller 5 is lower than the bottom surface of the paving element 1. Preferably, the protrusion 6 is 20 to 30 mm lower than the bottom surface of the paving element 1. It is ensured that the protrusion 6 can be inserted into the concrete pavement during the rotation of the roller 5, thereby increasing the concrete vibration depth and improving the concrete density.

[0021] In the present invention, the angle steel is an unequal-leg angle steel, and the length of the vertical side 12 thereof is greater than the length of the horizontal side 11 .

[0022] In the utility model, an oblique support 7 is provided between the fixing plate 2 and the angle steel to improve the supporting stability of the fixing plate 2 .

[0023] In the utility model, the protrusion 6 is a conical protrusion structure, which is convenient for inserting into the concrete pavement.

[0024] The operation process of the utility model is as follows: the paving element 1 is placed on the templates on both sides of the concrete pavement. If the pavement is wide, the paving element 1 is placed on one of the templates. The horizontal side edges 11 of the template paving elements 1 on both sides of the concrete pavement are in horizontal contact with the upper plane of the template, and the device is pulled forward at a uniform speed. The vibrator 3 is turned on to vibrate the concrete pavement. During the forward movement of the device, the roller 5 rolls forward, and the protrusions 6 are inserted into the concrete pavement one by one, increasing the vibration depth of the concrete pavement, facilitating the discharge of bubbles in the deep, improving the density of the concrete pavement, and at the same time helping to flatten the concrete pavement. During the subsequent forward movement of the paving element, the concrete is flattened to ensure the flatness of the pavement.
