2. Description of the Related Art Interlocking blocks are used on sidewalks and plazas in parks, sidewalks with arcades, garages of houses, and areas around entrances. Interlocking Block manufactures ultra-hardened concrete by high-vibration pressure and immediate demolding. It can withstand heavy objects due to the interlocking effect against shearing and can draw beautiful patterns with various colors and shapes in combination to have a scenic value.

[0003] Generally, an interlocking block is constructed by laying a lower roadbed and an upper roadbed on a roadbed, forming a sand cushion thereon, and laying it here.

The interlocking block is made of various materials such as lightweight concrete, brick, tile, natural stone, and rubber-like concrete, in addition to concrete.
In addition, there is also a material in which natural stone or artificial stone is used as a surface material and concrete is used as a backing material.

[0005]

In the conventional method of installing interlocking blocks, the interlocking blocks are arranged one by one at the site, and the joints are filled with sand. For this reason, it is extremely difficult to apply a flat surface, and the surface often becomes uneven after the application.

[0006] The conventional interlocking block is liable to slip when it rains and its surface becomes wet with water, and some people slip and injure. The present invention forms an interlocking block having excellent appearance into a single panel to facilitate on-site construction, prevent uneven surface after construction, and prevent people from slipping even when wet with water. An object of the present invention is to provide an interlocking block panel having a surface layer.

[0007]

According to the present invention, a flat plate is molded with a composition comprising natural crushed stone particles, ceramic fine hollow particles, siliceous fine powder, reinforcing fibers, an alkali metal silicate aqueous solution and the same curing agent. A plurality of interlocking blocks are attached as a surface layer.

The ceramic fine hollow particles used in the composition forming the interlocking block have a compressive strength of 600 kgf / cm ² or more and a bulk specific gravity of 0.3 to 0.5 g.
By using a material having physical properties of / cm ³ and a melting point of 1500 ° C. or higher, the effect of preventing slippage can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction performance can be improved by attaching a plurality of interlocking blocks to form a panel as if it were a single panel. These can be constructed in a natural arrangement even with a locking block. For this reason, it has become possible to produce interlocking blocks of various irregular shapes which have not been seen before.

The flat material used as the base material of the interlocking block panel of the present invention may be any of inorganic, organic, and wood materials, and is selected according to the place where the interlocking panel is used. In the case of outdoor use, an inorganic or organic flat plate material is used, and in the case of indoor use, an inorganic or organic wood material can be used.

The interlocking block adhered to the surface side of the interlocking block panel has a compressive strength of 600 kgf / cm ² or more and a bulk specific gravity of 0.3 to 0.5 g using an alkali metal silicate aqueous solution and the same curing agent as a binder.

These may be used alone or in combination of two or more. Of the above, alkali metal hydroxides can be more preferably used. 2 to 15 parts per 100 parts by weight of the aqueous alkali metal silicate solution
Add by weight.

[0014] If necessary, in order to improve properties, an anti-sagging agent, an anti-settling agent, an anti-freezing agent and the like may be added. Further, for the purpose of improving the performance, a plasticizer for giving flexibility, a stabilizer for preventing deterioration due to heat or light, a fungicide for preventing the occurrence of mold, and the like may be added.

On the surface of the interlocking block panel, ceramic fine hollow particles having high strength are joined to each other,
Since it is fixed and pressurized during molding, it becomes dense and has high strength, and its surface has a large number of ceramic fine hollow particles. The surface of the fine hollow particles has a great effect on preventing slippage.

Since the ceramic fine hollow particles having high strength can exist completely in the form of a hollow body on the surface, the ceramic fine hollow particles are fixed to each other by point bonding, so that numerous countless capillary tubes can be formed in addition to point bonding. There is an air flow hole, and the air flow hole that appears on the surface makes it hard to slip even when wet with water.

The ceramic fine hollow particles can withstand high stress and shear force generated in the production process by using a material having a particularly high compressive strength as compared with the conventional fine hollow foam, and furthermore, the ceramic fine hollow particles can be subjected to additional heat. By pressing, a dense surface layer can be obtained despite its light weight.

The compressive strength of the ceramic fine hollow particles or the fine hollow foam is synonymous with the water pressure resistance. The compressive strength is measured by pressing the fine hollow foam in water and applying the pressure applied to the water to the fine hollow foam. The pressure transmitted to the foam and broken by the fine hollow foam is defined as the compressive strength.

An interlocking block capable of exhibiting excellent performance must have sufficient stirring and kneading steps, and is particularly important for a high quality interlocking block with a uniform product. None of the conventional fine hollow foams could withstand such high pressure, and none of them could be used as such a surface layer to obtain sufficient performance. That is, most of them were destroyed, and the air flow holes could not be formed by the point joining.

The melting point of the fine hollow ceramic particles is 1500 ° C. or higher. Naturally, the fine ceramic hollow particles are caused by their material, but generally, the higher the melting point, the higher the compressive strength. Compressive strength of 600kgf / c
If m ² or more, its melting point becomes 1500 ° C. or more.

As described above, the ceramic fine hollow particles are composed of 50 to 60% of silica, 40 to 45% of alumina,
A foam obtained by foaming a ceramic composition of about 2.5% is used. Its physical properties are compressive strength 700kgf /

And consists only of complete hollow particles. The particle size of the ceramic fine hollow particles is in the range of 5 to 350 μm, and the fineness is adjusted to 20 parts by weight as finer 5 to 75 μm, medium 75 to 150 μm, coarse 150 to 350 μm,
A mixture of 20 parts by weight of a medium mesh and 30 parts by weight of a coarse mesh is used.
The bulk specific gravity is heavy for fine particles and light for rough ones. For this reason, the range of the bulk specific gravity is 0.3 to 0.5 g / cm ^3.
However, the particle size adjusted is about 0.36 g / cm ³ .

With respect to 100 parts by weight of the aqueous alkali metal silicate solution, 50 to 50 parts by weight of the ceramic fine hollow particles are added.
250 parts by weight. If the amount is less than 50 parts by weight, the anti-slip property, the weight reduction and the heat insulation cannot be sufficiently exhibited, and if the amount is more than 250 parts by weight, the physical properties are greatly reduced. The amount of ceramic fine hollow particles is adjusted according to required physical strength, specific gravity, and the like.

The natural stone used as a raw material of the natural crushed stone particles may be any of granite, andesite, marble, serpentine and the like, and is not limited. Natural crushed stone particles are fine, medium, and coarse, and the diameters of fine particles are adjusted to 0.1 to 0.5 mm, medium to 0.5 to 1.5 mm, and coarse to 1.5 to 3.4 mm, respectively. To use. Fine grain size adjustment of natural crushed stone 40
It is mixed and used as parts by weight, 30 parts by weight of medium mesh, and 10 parts by weight of coarse mesh. The range is 50 to 800 parts by weight of natural crushed stone particles with respect to 100 parts by weight of the aqueous alkali metal silicate solution.

The siliceous fine powder used in the present invention is silica fume, fly ash, quartz sand, quartzite powder, clay, kaolin, talc, crushed ceramic, blast furnace slag crushed slag,
Granulated blast furnace slag, siliceous duct and the like can be used. These have an average particle size of about 1 μm and a specific surface area of 200,000 cm ² / g.
Position is preferred. Among the above, silica fume, silica powder,
Granulated blast furnace slag is suitable. 20 to 100 parts by weight are added to 100 parts by weight of the alkali metal silicate aqueous solution.

The reinforcing fiber has a diameter of 13 μm or less and a length of 1 to 5
mm short fiber. The reinforcing fiber has a higher tensile strength as the diameter is smaller, and the diameter is 13 μm or less.
/ Cm ² or more.
The reason why the short fibers have a length of 1 to 5 mm is that the fibers can be uniformly dispersed without entanglement during stirring and kneading. The material of the reinforcing fiber may be any of glass fiber, polypropylene, vinylon, nylon, carbon fiber and the like. The amount of the reinforcing fiber to be added is in the range of 0.5 to 8 parts by weight based on 100 parts by weight of the aqueous alkali metal silicate solution.

The adhesive used for attaching a plurality of interlocking blocks to the flat plate may be either an organic or inorganic adhesive. It is also possible to apply a cement mortar to the surface of a flat plate material, and to attach an interlocking block on this.

The shape and dimensions of the interlocking block can be arbitrarily designed, and the dimensions are free and varied, and square, rectangular, triangular, round, and other special shapes are possible. . This is because the dimensions can be arbitrarily large, and a plurality of these are collectively formed into one panel.

Since natural crushed stone particles are blended into the surface layer of the interlocking block panel, various stone-grain patterns can be produced depending on the type of the natural crushed stone particles. In addition, the surface of the mold at the time of this molding can be made into a natural stone pattern with irregularities, and the surface can be polished to produce a marble tone with a glossy surface.
