Description

Stone tiles, methods for manufacturing the same, and apparatuses used in the methods

The present invention relates to a stone tile, a method for manufacturing the same, and an apparatus used in the method. More specifically, the height of the protrusion is formed to be low, and thus the cleaning is easily performed by forming a gentle curve between the protrusion and the groove. The present invention relates to a stone tile, a method of manufacturing the same, and an apparatus used in the method, which have a beautiful appearance and can simultaneously exhibit the effects of acupressure.

Stone tile, which is widely used for interior and exterior materials of buildings, functions as surface decoration of plate-like stone, such as granite, and performs both decorative and anti-slip functions. For example, as a exterior, a stone tile with various protruding patterns is mainly used to emphasize the decorative function, and for interior use, it is attached to the floor of a humid indoor space such as a bath or a toilet, and it is a slippery effect. It is generally processed to form a plurality of protrusions on the surface in order to reap.

In the conventional stone tile having such a function, as shown in FIG. 1, the protrusions 2 formed on the surface are formed to maintain sharp edges as they are formed by cutting of the cutting saw so that the edges of the protrusions 2 are formed. It can be easily broken.

Moreover, such a conventional stone tile exhibits an inexhaustible appearance since the shape of the protrusion 2 includes sharp edges as it is, and this stone tile has been used for interior decoration to decorate the floor of a bathroom or toilet in a building. At the time, even when contacting the human body and the corners of the stone part 2 of the stone tile, there was a problem that can damage the human body.

Accordingly, the Applicant cuts and / or polishes the edges of the stone portion 2 of the stone tile by secondary processing, as shown schematically in FIG. New stone tile processing method that can prevent the breakage of the corner of the stone part 2 and provide a processed stone tile so as not to cause damage to the human body even when contacting the human body and the corner of the stone tile. Was developed and filed with Korean patent application No. 98-3984 on February 11, 1998.

On the other hand, the stone tiles in which the protrusions 2 are formed may have a great height difference between the protrusions 2 and the grooves, and thus have an excellent effect on the acupressure effect, but rather, dust introduced into these grooves by the formation of grooves that are too deep. There was a problem in that contaminants such as are not easily removed by cleaning. Therefore, when it is intended to be used for decoration, such as the floor of the bathroom or in particular, the exterior wall of the building, the stone tiles lose the cleanliness by these contaminants, rather the adverse effects on the decorative effect by the stone tiles used to occur.

An object of the present invention is formed so that the height of the protrusion is formed to be a smooth curve between the protrusion and the groove is formed to be easy to clean, beautiful appearance, made of a stone tile that can simultaneously show the effect of acupressure and its To provide a manufacturing method and a device used in the method.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 and 4, the stone tile according to the present invention is to be cut to 15 to 30 ° with respect to the traveling direction of the stone plate 1 to be processed cutting saw 15 The groove formed by the cutting by a part of the cutting saw to form a curved arc gently bent downwards so that the first cutting groove and the second cutting groove to cross at a predetermined angle, such as 90 ° at least two times repeated processing. It is characterized in that it is made by forming a plurality of protrusions (2) to be arranged in a rectangular or other lozenges.

As the cutting saw is inclined at 15 to 30 ° with respect to the advancing direction of the slab 1, the slab 1 is cut to form a groove, so that the cross section of the groove forms a circular curved bent downwardly. There is a feature of the invention, in particular by adjusting the depth of the groove to be formed so that the depth of the groove is not relatively deep can be formed so that the height of the projection (2) relatively low, thereby easy to clean, beautiful appearance, It is possible to produce a stone tile that can simultaneously exhibit the effect of acupressure. When the inclination with respect to the advancing direction of the slab 1 of the cutting saw is less than 15 °, there may be a problem that the cross section of the groove formed between the protrusions 2 is not formed in a smooth arc shape intended in the present invention. On the contrary, if it exceeds 30 °, the cross section of the groove formed between the protrusions 2 may have a problem of forming a shape near a straight line rather than a gentle arc shape intended in the present invention.

In the method of manufacturing a stone tile according to the present invention as described above, the stone slab is first cut to have a predetermined thickness from the raw stone, and inclined at 15 to 30 ° with respect to the advancing direction of the slab while advancing the cut slab in one direction. Cut one side of the slab with a saw. In this way, a groove having an arcuate cross section is formed along the traveling direction of the slab, and when called as the first direction, the slab with the groove formed along the first direction is rotated by 90 ° or a predetermined angle to the first plate. A groove different from the groove formed along the direction can be formed. Subsequently, the above cutting process is repeated to cut the slabs to form grooves having a circular cross section at a predetermined depth along the second direction inclined at a predetermined angle or perpendicular to the first direction to cross each other. By the formation of the protrusions, protrusions are formed between these intersecting grooves, and stone tiles according to the present invention as shown in FIGS. 3 and 4 can be obtained.

In the cutting of slabs, the slab processing step is performed by cutting into slabs by cutting the slabs into horizontal and vertical and 20 to 30 mm thickness within the range of 150 to 900 mm from the raw stones.

A plurality of cutting saws are mounted between them while advancing the processed slabs in one direction to rotate the rotating shafts so that the cutting saws are separated from each other by a predetermined distance so that the cutting saws are cut to the slabs to a predetermined depth. An arc-shaped groove is formed at a predetermined depth along the first direction.

The slab with grooves formed along the first direction is continuously rotated by 90 ° or rotated by a predetermined angle in the rotating step, and then rotated by 90 ° or a predetermined angle with respect to the first direction in the same or similar manner as described above. Along the second direction, a groove having an arcuate cross section can also be formed.

The spacer used to mount the plurality of cutting saws on the rotating shaft by being spaced apart from each other is not separately illustrated, but is mounted on the rotating shaft together with the cutting saws between the plurality of cutting saws to cut the cutting saw. It may be a disc-shaped synthetic resin plate or aluminum metal plate having a predetermined thickness for the function of separating them from each other, but the present invention is not limited to these, can maintain a constant mechanical strength, preferably a lightweight material Of course it can be understood that anything can be used.

The thickness of the spacer corresponds to the width of the protrusion formed on the surface of the slab, so that the thickness of the cutting saw naturally becomes the separation distance between the protrusions.

In addition, the cutting depth in the primary processing step may be arbitrarily set in consideration of the size of the slab to be processed and the appearance of the stone tile to be manufactured.

The shape of the upper end of the protrusion may be variously embodied from a square to a lozenge or the like by adjusting the angles of the first direction and the second direction, and it will be obvious to those skilled in the art.
