Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an interlocking block panel, and is used particularly for a sidewalk or a plaza in a park, a sidewalk with an arcade, a rooftop, a garage of a house, a doorway, a garden stone of a house, a veranda, and other interior flooring materials of a building.

[0002]

[Prior art]

 Interlocking blocks are used for sidewalks and squares in the park, sidewalks with arcades, residential garages, and entrances. The interlocking block manufactures ultra-hardened concrete by a high-vibration pressure immediate release method. It can withstand heavy objects due to the interlocking effect against shearing, and it can be used to draw beautiful patterns in various colors and shapes, and has a scenic value.

[0003] In general, 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. Others use natural stone or artificial stone as the surface material and concrete as the backing material.

[0005]

[Problems to be solved by the invention]

 The conventional method of installing interlocking blocks is to arrange them one by one on site and fill the joints with sand. For this reason, it was extremely difficult to construct a flat surface, and the surface often became irregular after construction.

[0006] Conventional interlocking blocks have become more slippery when it rains and the surface is wet with water, and some people have slipped and injured. The present invention forms an interlocking block with excellent appearance into a single panel, facilitating on-site construction, preventing uneven surface after construction, and allowing people to slide even when wet with water. The purpose is to provide an interlocking block panel with no surface layer.

[0007]

[Means for Solving the Problems]

 In the present invention, a plurality of interlocking blocks formed of a composition comprising natural crushed stone particles, ceramic fine hollow particles, reinforcing fibers, and synthetic resin are adhered to the surface of a flat plate.

[0008]

[Embodiment of the invention]

 By attaching a plurality of interlocking blocks to form a single panel, not only can the construction performance be improved, but also the interlocking blocks of any irregular shape can Work can be done in an array. For this reason, it has become possible to fabricate interlocking blocks of various irregular shapes that have not been seen before.

[0009] The flat material serving 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. For outdoor use, inorganic or organic flat materials can be used. For indoor use, inorganic or organic wood materials can be used.

The interlocking block adhered to the surface side of the interlocking block panel has a compressive strength of 300 kgf / cm ² or more, a bulk density of 0.3 to 0.5 g / cm ³ , and a melting point of 1300 ° C. or more using a synthetic resin as a binder. The ceramic fine hollow particles are mixed with natural crushed stone particles and reinforcing fibers.

The synthetic resin used is preferably of an emulsion type, for example, an acrylic resin emulsion, a vinyl acetate emulsion, a vinyl chloride resin emulsion, a vinylidene chloride resin emulsion, a styrene / butadiene resin emulsion, and an epoxy resin emulsion.・ Polyester resin emulsions and copolymers of acrylic acid esters, styrene, ethylene, vinyl esters, vinyl acetate, synthetic rubber, etc.

For example, copolymers of these include acrylic / vinyl acetate copolymers, vinylidene chloride / butyl acrylate copolymers, ethylene / vinyl acetate copolymers, and the like. The amount of the synthetic resin emulsion composition used is in the range of 5 to 30% by weight. If it is less than 5% by weight, the physical properties do not increase, and if it is more than 30% by weight, the stability decreases.

In order to improve the properties of the synthetic resin emulsion, if necessary, various surfactants as a dispersant, an emulsifier for stabilizing the emulsion, an anti-wrinkling agent for the emulsion, a thickening agent, an anti-sagging agent, An anti-settling agent, anti-freezing agent, etc. may be added. Further, for the purpose of improving the performance, a plasticizer for giving flexibility, a stabilizer for preventing deterioration due to heat and light, a fungicide for preventing the occurrence of mold, and the like may be added.

On the surface of the interlocking block panel, high-strength ceramic fine hollow particles are joined together and adhered to each other, and they are fixed and pressed during molding. The particle surface has a significant effect on sliding up.

[0015] The ceramic fine hollow particles can withstand high stress and shear force generated in the production process by using a material having particularly high compressive strength as compared with the conventional fine hollow foam. 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, and 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. The compressive strength is the pressure transmitted to the foam and broken by the fine hollow foam.

An interlocking block capable of exhibiting excellent performance must have a sufficient stirring and kneading process, and is particularly important for a high quality interlocking block with a uniform product. There was no conventional fine hollow foam capable of withstanding such a 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 it was not possible to make air flow holes due to point joining.

The melting point of the ceramic fine hollow particles used is 1300 ° C. or higher. Naturally, the fine hollow ceramic particles are caused by their material, but generally the higher the melting point, the higher the compressive strength. If the compressive strength is 300 kgf / cm ² or more, its melting point is 1300 ° C. or more.

As described above, as the ceramic fine hollow particles, those obtained by foaming a ceramic composition comprising 50 to 60% of silica, 40 to 45% of alumina, and 1.5 to 2.5% are used. Its physical properties include a compression strength of 300 kgf / cm ² or more, a melting point of 1300 ° C. or more, a bulk specific gravity of 0.3 to 0.5 g / cm ³ , and a thermal conductivity of 0.1 (kcal / mhr ° C.). ing. 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, 20 parts by weight, and the fineness is adjusted to 5 to 75 μm, medium to 75 to 150 μm, coarse to 150 to 350 μm Parts, and 30 parts by weight of coarse powder are mixed and used. The bulk specific gravity is heavy for fine particles and light for coarse ones. Although the scope of this for the bulk specific gravity is 0.3 to 0.5 g / cm ^3, obtained by the particle size adjustment is 0.36 g / cm ³ before and after.

The amount of the ceramic fine hollow particles to be added is 10 to 50 parts by weight based on 100 parts by weight of the synthetic resin emulsion. If the amount is less than 10 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 50 parts by weight, the physical properties are greatly reduced. The amount of the ceramic fine hollow particles is adjusted according to the required physical strength, specific gravity and the like.

The natural stone used as the 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. Fine particle diameter is 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. To use. In addition to natural crushed stone particles, silica sand, silica stone powder, fly ash, silica fume, clay, talc, kaolin, crushed ceramic, crushed blast furnace slag, siliceous dust, and pigments may be added. For the particle size adjustment of natural crushed stone, use 40 parts by weight of fine, 30 parts by weight of medium, and 10 parts by weight of coarse.

The reinforcing fiber is a short fiber having a diameter of 13 μm or less and a length of 1 to 5 mm. This is because the smaller the diameter of the reinforcing fiber is, the higher the tensile strength is, and if the diameter is 13 μm or less, a tensile strength of 100 kgf / cm ² or more can be obtained. The reason for using short fibers having 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 and carbon fiber.

The adhesive used for attaching a plurality of interlocking blocks to a flat plate material may be any of an organic or inorganic adhesive, but may be a synthetic resin used as a binder for an interlocking block to be attached to the surface. Adhesives containing the same synthetic resin as a main component are more preferable. It is also possible to apply a cement mortar to the surface of a flat plate, and to attach an interlocking block on this.

[0024] The shape and dimensions of the interlocking block can be arbitrarily designed, and the dimensions are free and varied. Square, rectangular, triangular, round, and other special shapes such as irregular shapes are possible. is there. This is because the dimensions can be arbitrarily large, and a plurality of these can be combined into one panel.

Since natural crushed stone particles are blended in 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 molding can be made into a natural stone pattern with irregularities, and the surface can be polished to produce a marble tone with excellent gloss on the surface.
