Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reusing waste roof tiles, and more particularly to a method for reusing waste roof tiles by effectively reusing the waste roof tiles by performing an optimal construction process.

[0002]

2. Description of the Related Art In recent years, as environmental regulations have become stricter, more and more industrial wastes have been required to be treated. In addition, from the viewpoints of global environmental issues, resource conservation, and difficulty in locating waste disposal sites, etc., instead of simply disposing of industrial waste, such as landfill, safety with the aim of zero mission,
Many proposals have been made as the motivation for effective reuse has increased.

For example, it is directed to reuse industrial waste as an aggregate for safe and large-scale use.

[0004] For this reason, by melting the incineration ash of municipal waste and earth and sand contaminated with harmful substances, the harmful substances are decomposed in the melting process, or the molten substances are confined in a stable state in the melt. A method has been proposed to produce the melt processed product as aggregate.

A method of crystallizing by generating crystal nuclei has also been proposed. In the example disclosed in Japanese Patent Publication No. 1-247739, the incineration ash having the adjusted components is melted and then rapidly cooled, Although crystal nuclei are generated by thermal shock and heat retention is carried out again to crystallize it, but it is crushed during thermal shock or cracks occur at the same time as crushing. The body was in a situation where it could not be manufactured and lacked the freedom to produce aggregate of the desired size.

On the other hand, the use of industrial waste as a ground material is also being considered, and as a part of that, ash formed by incinerating sludge discharged from a paper mill (hereinafter,
PS ash) is promising.

However, since PS ash has a large grain size portion corresponding to sand content and its grain size is too uniform, PS ash is mixed with cement and water to form a slurry, and backfilling is carried out. In order to generate it as a material, the fluidity was extremely deteriorated, and it was difficult to pump it during construction.

In addition to this, since the clay content generated in the washing step during the production of mountain sand has a large water content, it is difficult to use it as a versatile backfill soil when used alone. As described above, the reality is that it has not been effectively used even for industrial waste that must be generated.

As described above, although it is generated as so-called industrial waste, it is generated as industrial waste because the most suitable use for recycling and a method of processing into a form suitable for the use have not been established. However, it has been pointed out that there is still a large amount of waste that is not reused as a result.

Among them, roof tiles, which are indispensable for use in many detached houses, have been diversified in specifications such as shape and color, and therefore, generate more scraps than expected. Therefore, even in the housing industry, there is no suitable countermeasure for the treatment as industrial waste, and therefore an improvement measure has been desired.

BEST MODE FOR CARRYING OUT THE INVENTION The method for reusing waste roof tiles according to the present invention comprises a step of collecting and accumulating waste roof tiles, and crushing the waste roof tiles into granular materials having a plurality of particle sizes in stages. And a step of separating into granular materials of different particle sizes.

An embodiment of the method for recycling a waste roof tile according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic view showing an embodiment of the present invention. In the figure, a house 1 for treating waste roof tiles has a crusher 2, a conveying section 3 separated for each particle size, and each particle size. It is composed of a silo group 4 of shaped granules.

The waste roof tiles 5 collected from each construction site and the like are collectively put into the crusher 2 and crushed inside thereof. The crushed waste roof tiles 5 are separated from the upper portion by the particle separating units 11, 12, and 13 to provide coarse particles 6 having a particle size of 5 mm or more and 7 mm or less, fine particles 7 having a particle size of 3 mm or more and less than 5 mm, and further a particle size. Sand grain content less than 3 mm 8
It is gradually separated and gradually descends.

Coarse-grained portion 6 and fine-grained portion 7 which have been shaped and separated
The sand grains 8 are transferred from the respective outlets 9 to the respective conveyors 10 forming the transport unit 3, and are transported to the silo group 4 for the respective grains by the transfer of the conveyor 10. The silo group 4 is composed of silos 14, 15 and 16 and is stored in a state of being divided into a coarse grain component 6, a fine grain component 7 and a sand grain component 8.

In the present embodiment, the waste roof tile 5 is crushed and separated as described above and stored in the silo group, but the waste roof tile 5 is crushed, separated and stored in these embodiments. The present invention is not limited, and various machines conventionally used conventionally can be appropriately used.

However, since the roof tile is inherently a porous baked product, each crushed and shaped grain portion is essentially hydrophilic and breathable.

Therefore, in the method for reusing a waste roof tile according to the present invention, the grain size of each particle is appropriately adopted, and at the same time, the above-mentioned characteristics of the roof tile can be effectively utilized to make a waste roof tile. We are trying to reuse.

FIG. 2 shows an embodiment of the present invention, which is an example in which a block is formed by forming a coarse particle content and a fine particle content in a predetermined particle size distribution.

The block 20 shown in this embodiment is composed of a coarse grain 6 having a particle size of 5 mm or more and 7 mm or less and a particle size of 3 mm or more and 5 m.
It is made up of fine particles 7 of less than m, and while effectively eliminating the use of various aggregates and concrete, the hydrophilicity and breathability of the discarded roof tiles are effectively utilized to fully exert the function as a block. ing.

The block 20 can be formed in a variety of color patterns by coloring the waste roof tiles while forming the blocks in the same manner as a normal block made of concrete. Not only is the waste roof tiles reused, but also the color is changed. It also has the advantage of being able to build rich block walls.

FIG. 3 shows another embodiment of the present invention, which is an example in which the surface layer portion is backfilled to a predetermined depth, and FIG. 3 (a) is a conceptual diagram of a schoolyard and antuca. Figure 3
(B) is a partial cross-sectional view of the schoolyard and Antuca.

Since a normal schoolyard is composed of clay soil, its surface is hard and hardened due to poor water permeability, and water is not collected well even in rainy weather, causing a pool of water and slipping. There was a risk of falling due to a fall, and it was necessary to be concerned about injuries due to a fall or the like during exercise of the child.

However, as in the present embodiment shown in FIG. 3 (a), the surface layer portion 22 of the schoolyard 21 is filled to a predetermined depth with the sand grains 8 having a grain size of less than 3 mm formed from the waste roof tile. If you put it back, you can prevent such a danger.

That is, as shown in the cross section of FIG. 3 (b), the sand grains 8 formed from the waste roof tile backfilled to a predetermined depth have hydrophilicity and air permeability. , Schoolyard 2
When 1 is dry, it exhibits a great elasticity due to its breathability, and when it rains in the rain, the surface layer 22 sucks rainwater and eliminates the pool of water, which may cause slipping and falling. Have been eliminated.

On the other hand, in the Antuca 23 shown in FIG. 3 (a), since the goodness of the drainage is mainly taken into consideration, coarse soil particles are selected on the runway, and the soil particles are laid. The coarse particles of the soil did not stop the scratches when falling.

However, in the method for reusing a waste roof tile according to the present invention, as shown in FIG. 3 (b), a fine particle fraction 3 having a particle size of 3 mm or more and less than 5 mm and a particle size of 3 mm formed from the waste roof tile. By embedding a grain mixture of a sand grain component 8 of less than 8 in a surface layer 24 having a predetermined depth, it is possible to prevent the risk of scratches due to a fall, which the conventional Antuca 23 had. Is.

That is, in this case as well, as in the embodiment of the schoolyard 21, the particles formed from the discarded roof tiles are the same as the Antuca 2
While maintaining the good water handling and running performance required by No. 3 by breathability and hydrophilicity, it also eliminates the risk of scratches by forming fine particles of loam particles and sand particles, and at the same time provides appropriate elasticity. By providing the surface layer 24 with moisture and dampness, the convenience of the track is enhanced.

In addition, as another embodiment, coarse particles having a particle size of 5 mm or more and 7 mm or less and fine particles having a particle size of 3 mm or more and less than 5 mm, which are formed from a waste roof tile, have an appropriate particle size distribution. It is also effective to backfill into the surrounding area such as earth pipes buried in the soil while mixing, and the backfill material for earth pipes is required due to the air permeability and hydrophilicity of the particles formed from the discarded roof tiles. It is possible to arbitrarily establish the good water-holding performance and the elasticity between the laid ground.

Further, an appropriate composition of coarse particles having a particle size of 5 mm or more and 7 mm or less, fine particles having a particle size of 3 mm or more and less than 5 mm, and sand particles having a particle size of less than 3 mm, which are formed from waste roof tiles on arbitrary soil. The embodiment that mixes the granular material composed of the above to create the plant culture soil, ensures the retention of air and water in the culture soil by the air permeability and hydrophilicity of the grains formed from the waste roof tiles. It greatly exerts the effect of increasing the growth of the plant to be planted.

Although the embodiment of the method for reusing the discarded roof tile according to the present invention has been described in detail with reference to the drawings, the present invention is not limited to the above-mentioned embodiment and is discarded. Recycling of waste roof tiles can be meaningfully developed if the application that maximizes the characteristics of air permeability and hydrophilicity that the particles formed from roof tiles have in relation to the particle size to be created. is there.
