Abstract

PURPOSE: To enhance the strength and the beauties of blocks by forming the whole surface of a front layer of concrete blocks with permeable resin or gas which incorporates light emitting elements, and provides pressure resistance and durability to a satisfactory extent. CONSTITUTION: A front layer 1 comprises hard resin having satisfactory strength and permeability or glass having satisfactory strength where a light emitting thin sheet metal is sealed with an upper layer sheet 2 and a lower layer sheet 4. Then, a cylindrical body 8, which is designed to extend a lead wire 5 of a light emitting element 3 outside a concrete block, is installed to substantially the center of the lower layer sheet 4. Then, the light emitting element 3 uses an electroluminescence light emitting element, for example. After the front layer 1 is set to the bottom of a form in the shape of a specified contour, concrete is filled up in there and press-molded so that the front layer 1 may be integrated with the concrete block. This construction makes it possible to prevent a drop in the strength of a pavement, and enhance a luminescent effect and provide a design effect by marking a light emitting portion like well- arranged patterns.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interlocking block for paving, and provides a light emitting interlocking block for paving in which the entire surface of the surface layer of the interlocking block emits light.

[0002]

2. Description of the Related Art In interlocking block pavement, for example, concrete blocks having a predetermined outer shape of about 200 × 100 mm and a thickness of about 80 mm are combined and arranged on a roadbed adjusted with a sand cushion,
A pavement surface is formed by applying high vibration pressure to this concrete block, which is a laid combined concrete block pavement.

In such interlocking block pavement, by selecting various shapes, color tones, surface textures, laying patterns, etc. of individual concrete blocks, a pavement surface that matches the surrounding environment is formed and the landscape is improved. It is widely used in parks, outdoor playgrounds, roadways, sidewalks, parking lots, etc. because it can be used for rainwater and it is easy to return rainwater to the ground.

The concrete block used for the interlocking block pavement is basically manufactured by mixing cement, sand, aggregate and a small amount of water, filling a predetermined formwork and pressurizing it. There is.

Further, the interlocking block exhibits various color tones by mixing a colorant in the surface layer or polishing the surface layer at the time of manufacturing the interlocking block.

[0006] Recently, there is one in which a road surface light emitting system that serves both as an illumination and a decoration is attached by attaching illuminations to a paved surface paved with concrete such as a concrete flat plate and making it emit light at night.

In this system, a method of embedding a light-emitting body in which a light-emitting body such as a light-emitting diode is embedded in a hollow portion of a concrete block is used.

[0008]

By the way, in the method of embedding the luminous body described above, either the concrete block must be hollowed in order to embed the luminous body, or the luminous body embedding hole must be provided in advance in the concrete block. However, this method cannot be directly used for interlocking pavement.

That is, since the concrete block used for the interlocking block is small, the strength of each block will be reduced if a measure such as hollowing is applied to the concrete block, and the power supply to the light emitter is arranged. The method of attaching the illumination to the paved surface cannot be directly applied because it is difficult to install.

Further, the above-mentioned light emitting system is basically point light emission, and a system in which the entire surface of the concrete block emits light has not been put into practical use due to problems such as insufficient strength of the pavement surface.

Therefore, it is an object of the present invention to provide an interlocking block which is capable of retaining a sufficient strength of the pavement surface and capable of emitting light from the entire surface of the surface layer in the interlocking block pavement. It is in.

[0012]

The above objects can be achieved by the present invention described below. That is, in the present invention, in a pavement interlocking block in which concrete blocks having a predetermined outer shape are combined and laid on a roadbed to form a pavement surface, the entire surface layer of the concrete block is provided with a light emitting element. However, the pavement light-emitting interlocking block is made of a translucent resin or glass having sufficient pressure resistance and durability.

In the light emitting interlocking block for pavement of the present invention, the light emitting element is preferably an electroluminescent light emitting element in order to achieve full surface emission of the surface layer of the interlocking block.

[0014]

The light emitting interlocking block for pavement of the present invention is made of a translucent resin or glass having a built-in light emitting element and having sufficient pressure resistance and durability over the entire surface of the concrete block used for paving the interlocking block. Since it was formed, without reducing the strength of the pavement surface,
The entire surface of the interlocking block can emit light.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete structure of a light emitting interlocking block for pavement of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded explanatory view of a surface layer containing a light emitting element used for an interlocking block pavement according to an embodiment of the present invention.

FIG. 2 is an explanatory view of a concrete block used for paving an interlocking block in which the surface layers are adhered.

The surface layer 1 is made of a hard resin having sufficient strength and translucency or a glass having sufficient strength, and has an upper layer plate 2 having a space inside which can accommodate a light emitting element, and a light emitting element. It comprises a thin element plate 3 and a lower layer plate 4 which is fitted in the space of the upper layer portion 1 and encloses the light emitting element thin plate 3.

A cylindrical body 8 consisting of an inner cylinder 6 and an outer cylinder 7 for extending the lead wire 5 of the light emitting element thin plate 3 to the outside of the concrete block 9 is formed in the substantially central portion of the lower layer plate 4. Are provided integrally with the lower layer plate 4 and through the lower layer plate 4.

In the surface layer 1, the light emitting element thin plate 3 and the lower layer plate 4 are fitted in the space of the upper layer plate 2, and the wall portion of the lower layer plate 4 and the inner wall of the space portion of the upper layer plate 2 are connected to each other. Can be formed by bonding.

In the light emitting interlocking block for pavement of the present invention, the electroluminescent light emitting element is most preferable as the light emitting element thin plate 3 in order to achieve full surface light emission.

The electroluminescent phosphor element is
It is generally called EL and is commercially available. For example, a back electrode formed of aluminum foil and an insulating layer formed on the back electrode, that is, a high dielectric constant organic resin is dissolved in a solvent, and It consists of an insulating layer formed by an ink in which barium titanate powder is dispersed therein, an electroluminescent light emitting layer formed on top of it, and a transparent electrode, which is entirely packaged in a highly moisture-proof film. .

The lead wire 5 is led out from the transparent electrode of the electroluminescent light emitting element.

The upper layer plate 2 is made of a colorless transparent or colored resin or glass having sufficient strength, and may be any one as long as it transmits the light of the light emitting element thin plate 3.

On the other hand, the lower layer plate 4 may be made of resin or glass that does not transmit light.

In order to integrate the surface layer 1 having such a structure with the concrete block 9 as shown in FIG. 2, first, the surface layer 1 is set in the lower part of the molding chamber having a predetermined outer shape having a depth of, for example, about 100 mm. Then, after pouring an adhesive into it, if necessary, it is filled with concrete in which sand, cement, crushed stone, and water are kneaded, and then press-molded to obtain a surface layer 1 and a concrete block 9 as shown in FIG. An integrated interlocking block can be obtained.

When the concrete is poured into the surface layer 1, the outer cylinder 7 of the cylindrical body 8 is slid to the maximum extent along the outer circumference of the inner cylinder 6 so that the concrete does not enter the cylindrical body 8. Concrete is added to the cylinder 8, and then the cylinder 8 and the entire concrete are simultaneously pressed, so that the outer cylinder 7 of the cylinder 8 contracts along the outer circumference of the inner cylinder 6, and the cylinder 8 is substantially centered on the concrete block 9. And the lower end of the cylindrical body 8 and the lower end of the concrete block 8 are flat.

In this way, the concrete block unit in which the cylindrical body 8 is arranged in the concrete block 9 is
The strength of the concrete block does not decrease as compared with the case where the concrete block is processed by the above-mentioned "opening" method.

Further, since resin or glass having excellent pressure resistance and durability is arranged on the entire surface of the concrete block, the load applied to the concrete block itself is dispersed. The concrete block will not be damaged.

In the light emitting interlocking block for pavement of the present invention, a bellows-shaped plastic may be used instead of the cylindrical body 8.

Further, the lead wire 5 can be wired through the concrete without using the cylindrical body 8.

[0032]

EFFECTS OF THE INVENTION The light emitting interlocking block for pavement according to the present invention having the above-described structure can emit light to the entire surface of the surface layer of the interlocking block without lowering the strength of the pavement surface. An excellent interlocking block pavement can be formed.

Further, the light emitting interlocking block for paving of the present invention can be used for all or a part of the paving surface of the interlocking block, and particularly when it is used for a part of the paving surface of the interlocking block,
An interlocking block pavement having a design effect can be formed by arranging the light emitting portions so as to appear in a pattern.
