Description

Sidewalk-block combined rice hulls layer and aggregate layer}

The present invention relates to a sidewalk block, and more particularly to an environmentally friendly and permeable sidewalk block produced using chaff.

In general, a sidewalk block that is passed by a person is a road pavement installed on a pedestrian path, and a concrete walkway block having excellent hardness, heat resistance, and weather resistance or inelastic pavement such as concrete, color cone, pitcher cone, and asphalt concrete is generally used.

However, these inelastic packages have a problem of poor walking feeling due to lack of elasticity and environmental pollution due to dust.

Recently, in order to solve the disadvantage of the inelastic package, the use of an elastic member, for example, an elastic package manufactured using a waste tire chip or a rubber chip, has been increasing.

However, the elastic packaging using recycled rubber chips has a complicated manufacturing process such as waste rubber collection, sorting, crushing, washing, drying, melting, product molding (roll sheet form or chip form, etc.), waste resin powder generation, There is a problem that may cause environmental pollution during grinding and processing, such as emissions of harmful gases during melting, or may cause environmental pollution during disposal, such as landfill or incineration.

Recently, to create an eco-friendly atmosphere using ocher blocks, this also has a problem that the water pooling phenomenon occurs seriously during heavy rain due to lack of permeability.

An object of the present invention for solving the above-mentioned problems is to provide a walkway block that is environmentally friendly, strong permeability and good walkability.

Sidewalk block is combined with the chaff layer and aggregate layer according to the present invention for solving the above problems, chaff layer and the chaff layer formed by stirring the resin and in a predetermined frame; Aggregate layer having a uniform size and the aggregate of the resin is formed in a predetermined frame; including, the chaff layer and the aggregate layer has a configuration that is bonded using an adhesive resin at room temperature.

Here, as the chaff layer is added to the fiber and stirred, the binding force can be further increased.

Here, the aggregate of the aggregate layer is characterized in that the natural aggregate or steelmaking slag of uniform size.

Here, the sidewalk block has a rectangular parallelepiped shape, and the other side edge portion facing one edge thereof preferably has an incision to ensure permeability.

According to the configuration of the present invention described above, it is possible to provide a sidewalk block that is environmentally friendly, strong permeability and good walking.

Hereinafter, the structure and manufacturing process of the sidewalk block is combined with the chaff layer and aggregate layer according to the present invention with reference to the accompanying drawings.

Figure 1a shows a cross-sectional view of the sidewalk block is combined with the chaff layer and aggregate layer according to the present invention, Figure 1b is a perspective view of the sidewalk block is combined with the chaff layer and aggregate layer according to the present invention.

As shown, the sidewalk block is combined with the chaff layer and aggregate layer according to the present invention is composed of the chaff layer 110, the bonding resin 120 and the aggregate layer 130.

The chaff used for the chaff layer 110 is chaff is used as it is in a natural state generated by refining rice ear. The rice husks have their own elasticity because they have a space inside the rice bran, and may vary in size depending on the rice variety. The chaff may also have a crushed and pressurized form and may provide improved durability by using crushed and pressurized chaff.

Fiber strands may be mixed to enhance the binding force of the chaff layer 110, the fiber strands to stick to the neighboring chaff serves to strengthen the bond between chaff. The fiber strands may be reinforcing fibers or fiber composite materials, and such fiber strands may be obtained from fibers, nonwoven fabrics, fabrics, reinforcing fibers, and the like, and natural fibers, synthetic fibers, and inorganic fibers may be applied as the fibers.

Chaff layer 110 may be composed of a combination of chaff and a resin, the resin is a thermosetting resin or a thermoplastic resin is used.

Bonding resin 120 is a resin that combines the chaff layer 110 and the aggregate layer 130 at room temperature, may be an epoxy-based resin, but is not limited to this, if the bonding resin capable of bonding the resin layer and the resin layer can be used. It is possible.

The aggregate layer 130 is a mixture in which aggregate and resin are combined, and the aggregate may be a natural aggregate obtained in a natural state, and may also use steelmaking slag.

Of course, natural aggregates or steelmaking slag should have a uniform size. This is because it is necessary to maximize the porosity in order to secure permeability, which is a requirement of the sidewalk block.

Steelmaking slag is a slag that is produced when steel is manufactured from molten iron. As such steelmaking slag remains unslagized quicklime during slag formation, it is aged to eliminate the cause of cracks or fractures due to volume expansion. It is preferable to use slag, and the aging technique can be applied by various known techniques.

Like the chaff layer 110, the resin mixed in the aggregate layer 130 may alternatively be used as a thermosetting resin or a thermoplastic resin.

Referring to FIG. 1B, the sidewalk block has a rectangular parallelepiped shape, and the other side edge portion facing the one edge portion has an incision 140 to ensure permeability. The formation of the cutout 140 may have a polygonal shape and does not necessarily have a rectangular parallelepiped shape. That is, the incision 140 serves as a permeability auxiliary role that can more efficiently increase the permeability guaranteed by the chaff layer 110 and the aggregate layer 130.

As the aggregate layer 130, although the aggregate is used in the present invention as a natural aggregate and steelmaking slag, it is also possible to use a concrete layer having good water permeability that can replace the aggregate layer 130.

The concrete layer may be composed of permeable cone and ascone, which is used for permeable or drainage paving, and ascone is used for asphalt (asphalt) and coarse aggregate (gravel), fine aggregate (sand) or It is a mixture of packing filler (mineral filler) at heating or room temperature. It is used for road pavement or parking lot. It is also possible to implement the sidewalk block according to the present invention by bonding the concrete layer consisting of such a pitcher cone or ascon with chaff layer and the joint resin.

Hereinafter, with reference to Figure 2 looks at the manufacturing process of the sidewalk block is combined chaff layer and aggregate layer according to the present invention.

First, Figure 2 is a flow chart showing the manufacturing process of the sidewalk block combined with chaff layer and aggregate layer according to the present invention.

Aggregate and resin are mixed (S210), while chaff and resin are mixed (S220). For the sake of convenience, the processes S210 and S220 are listed in a time series, but the order is meaningless and does not matter at the same time or in reverse order.

The mixed mixture is put in a predetermined standard frame and undergoes a molding process (S230). At this time, after molding the coating resin so that the bottom surface of the chaff layer 110 and the upper surface of the aggregate layer 130 is bonded (hardened at room temperature) (S240). When the curing is completed after a predetermined time elapses when the mold is removed by removing the standard frame (S250).

The manufactured sidewalk block can have elasticity by the chaff layer, which makes it possible to provide elasticity and convenience of walking, and also solves the problem of discharging harmful substances as an environmentally friendly material. On the other hand, the aggregate layer can compensate for the disadvantages of the mechanical strength of the rice hull layer, which is superior to the mechanical strength of the existing concrete sidewalk block, and the permeability of the sidewalk block is the aggregate layer and the incision by the chaff layer and uniform aggregate. This makes it possible to maintain good performance.
