[0003]

[Problems to be solved by the device]

 Conventional rubber chip pavement blocks have been problematic in that they require high-cost molds and press equipment because they are compression-molded using molds, and that large capital investment is required. Also, it is necessary to make a mold every time the shape of the block changes, and it is not possible to prepare various expensive molds corresponding to various shapes, and the shape of the paving block to be molded will be uniform. There was a flaw.

Further, the conventional rubber chip paving block has a drawback that a large rubber chip paving block cannot be manufactured because the size of the press equipment is limited.

The present invention provides a paving block made of recycled rubber chips that can be easily manufactured from a large sheet-like recycled rubber chip flat plate without the need for compression molding in a press facility using an expensive mold. That is the purpose.

In particular, most of the used rubber chips are recycled rubber chips (old tires, etc.), and the used recycled rubber chip flat pavement blocks of the present invention are chipped and re-cycled to save resources and save the environment. The aim is to prevent pollution.

In addition, we provide paving blocks made of recycled rubber chips that disperse the scent of flowers and flowers and the scent of citrus fruits such as lemons according to the scenery of the place to be paved, and it is as if in a meadow or an orchard. It is intended to make you feel like.

 Detailed description will be given with reference to the accompanying drawings showing an example of an embodiment of a paving block made of a recycled rubber chip flat plate according to the present invention.

FIG. 1 shows a pavement block in which a quadrant is cut out from a square and the quadrant is combined, and FIG. 2 is divided into a drum shape and a drum shape. Another example is a paving block showing another example in which FIG. 3 shows a grinding wheel in a state of chamfering, and FIG. 4 shows a sheet-shaped rubber chip flat plate which is still large and has a joint formed thereon.

The sheet-shaped rubber chip flat plate 1 as large as shown in the drawing has 610 kg of pigments of various colors, 19 g of catalyst (trade name: AD-UL), 5.4 kg of urethane adhesive (trade name: 6710). It has a composition containing 610 g of an additive (trade name: AD-50) for the purpose of reinforcing the adhesive to further enhance the adhesive effect. Then, stir with a hand mixer, add 24.5 kg of recycled rubber chips in the form of old tires to the mixture, mix for about 6 minutes, pour into a frame of appropriate size (not shown), and dry. It is a thing.

In addition, depending on the place where the paving is performed, in a park or the like, a fragrance such as a scent of flowers or other citrus fruits such as lemon may be mixed to give an atmosphere such as a steppe or an orchard.

The as-large sheet-shaped rubber chip flat plate 1 shown in FIG. 3 is punched with a punch (not shown) having an arbitrary shape to obtain rubber chip flat plate paving blocks 2, 3 and 4, 5, 6. Then, a mold is fitted on each surface or the surface of the sheet-shaped rubber chip flat plate 1 which is still large, and pressed to create a pattern. Here, the block 2 has a shape in which a quadrant having a radius shorter than the piece is cut out from one vertex of the square, and the block 3 has the shape of the quadrant. A block 4 is a drum-shaped rubber chip flat plate paving block, and blocks 5 and 6 are obtained by dividing the drum-shaped rubber chip flat plate paving block 4 in two at the central portion.

In order to remove burrs generated around these blocks 2, 3, 4, 5, 6 and for edging (frame patterning), a grinding wheel 8 was pressed around the burrs to scrape off the corners. Chamfer 7 is provided.

A block guide surface 9 shown in FIG. 3 is for guiding each block 2, 3, 4, 5, 6 by placing it on this guide surface 9, and rotating a grindstone at a necessary chamfering position of each block. It is arranged so that the car 8 is pressed and the chamfer 7 is applied to this necessary portion.

Since the pressing roller 10 is installed above the guide surface 9 near the grinding wheel 8, when the chamfering 7 is applied to the required chamfering points of each of the blocks 2, 3, 4, 5, 6. The block is guided to the grinding wheel 8 and is pressed stably against the grinding wheel 8.

When changing the shape of the chamfer 7, it can be easily changed by changing the shape of the grinding wheel 8.

Further, as shown in FIG. 4, a trapezoidal convex portion 11 is formed around the sheet-shaped rubber chip flat plate 1 which is still large, and another convex sheet-shaped rubber chip flat plate 1 is formed on another sheet-shaped rubber chip flat plate 1. A trapezoidal concave portion 12 that fits in is molded into a joint portion 13.

Further, in order to increase the hardness of the paving blocks 2, 3, 4, 5 and 6, as is well known, rubber chips may be mixed with gravel.

[Effect of device]

 As described above, the present invention does not require an expensive mold or press equipment for manufacturing the sheet-shaped recycled rubber chip flat plate 1, and therefore can be manufactured at low cost.

The pavement blocks 2, 3, 4, 5, 6 made of recycled rubber chip flat plates do not have to be compression-molded one by one with a mold, but sheet-like rubber chip flat plates using recycled rubber chips such as old tires manufactured at low cost. It is made by punching with a glass punched from 1. In addition, the punched glasses are inexpensive, can be prepared in large quantities, and can be manufactured in large quantities at a time, enabling mass production. Further, it is possible to prepare punched glasses of various shapes, and various shapes can be freely manufactured.

Various patterns can be implemented because a pattern is fitted by fitting a mold onto the surface of the blocks 2, 3, 4, 5, 6 or the surface of the sheet-shaped rubber chip flat plate 1 that is still large and pressing it. Is. Further, by chamfering 7 with the grinding wheel 8, various frame patterns can be implemented.

Further, in the present invention, the size of the mold, press equipment, etc. is not limited to the size of the paving blocks 2, 3, 4, 5, 6 made of recycled rubber chip flat plate. Therefore, it is possible to manufacture a paving block made of a large rubber chip flat plate, and if the joint portion 13 is formed around the sheet-shaped rubber chip flat plate 1 which is still large, it is possible to pave a large area such as a ball field, a gymnasium or a truck. It will also be convenient. Further, in this case, as shown in FIG. 4, the chamfering 7 is not applied to the periphery by the grinding wheel 8 so that no frame pattern is formed on the surface of the rubber chip flat plate paving block.

Also, as is well known, a rubber chip mixed with gravel has improved wear resistance, improved nonflammability, and is less likely to burn.

Further, in the present invention, most of the recycled rubber chips are used as the raw rubber chips (old tires etc.), but it goes without saying that raw rubber chips made of raw rubber or synthetic rubber may be used.
