  • Patent number: 10086643
    Abstract: Provided are a chip with a stereoscopic texture for a resin-based reinforced natural stone and a resin-based reinforced natural stone including the same. A chip with a stereoscopic texture can be obtained by coating a pigment on a surface of a crushed reinforced natural stone chip. In a resin-based reinforced natural stone to which the chip with a stereoscopic texture is added, a boundary surface between the chip and a matrix is formed, such that a texture of natural stone and a three-dimensional stereoscopic effect may be implemented, thereby making it possible to implement an aesthetically beautiful surface.

  • Patent number: 9938684
    Abstract: There is provided a guide assembly for guiding a cylindrical casing used in forming a sheathing wall in a ground. The guide assembly includes: a first guide-body having first inner and outer vertical faces and first top and bottom horizontal faces extending in a length-direction thereof; a second guide-body having second inner and outer vertical faces and top and bottom horizontal faces extending in a length-direction thereof, wherein the second inner face faces away the first inner face; at least one first coupling unit configured to couple the first and second guide-bodies to each other at the first and second top faces thereof; and at least one second coupling unit configured to couple the first and second guide-bodies to each other at lower positions of the first and second inner faces thereof.

  • Patent number: 9029436
    Abstract: An artificial silica marble comprises a matrix and a line pattern portion. The line pattern portion comprises fine lines having a width of about 50 to about 500 ?m and forms a web- or net-like pattern. The line pattern portion divides or partitions the artificial silica marble into a plurality of irregularly shaped pattern portions to form an amorphous pattern in the cross section of the artificial silica marble.

  • Patent number: 8475890
    Abstract: The present invention provides transparent chips with natural metal-like texture by coating silica-containing transparent chips with colored material, such as a metal powder, in a transparent resin as a base resin. The present invention also provides artificial stone with natural metal-like texture and patterns by mixing the colored material coated transparent chips and inorganic filler with a matrix resin. The artificial stone of the present invention can be prepared by mixing about 4 to about 24 parts by weight of inorganic filler and about 0.1 to about 5.0 parts by weight of the colored material coated transparent chips, per about 1 part by weight of the matrix resin. The colored material coated transparent chips can have a specific gravity of about 2.0 to about 2.65, while the matrix resin can have a specific gravity of about 2.2 to about 2.
