Using this method and the like, artificial marble products having excellent quality were produced and distributed.

As such, the conventional artificial marble is produced and supplied only as a plate, and thus, the artificial marble is limited to a method of forming a curved surface by mosaic-decorating a plate cut to a predetermined size or by bending or processing a portion of heat. Therefore, a whole artificial marble tube that could be used for finishing circular columns among interior decoration items such as architecture and furniture could not be provided.

Accordingly, in order to manufacture artificial marble circular pillars, the unit member is formed by dividing 1/2 to 1/4 into a predetermined size and thermally deforming it to a curved surface, and the circumferential surface of the pillar portion based on the artificial marble unit member is formed. A method of joining up and down while wrapping has been proposed. Further, as known in the Republic of Korea Patent Publication No. 1992-0021819 "artificial marble column and its construction method" artificial marble unit member while assembling the divided artificial marble unit member on the circumferential surface of the foundation column such as steel or steel frame After supporting the outside of the formwork, there was a method of pouring concrete into the interior and curing the artificial marble unit members are joined together to form a column.

In the method of manufacturing a pillar using the artificial marble unit member formed as the curved surface, the process of attaching each divided artificial marble unit member is complicated and cumbersome, and the manufacturing cost is increased, and the same texture can be expressed by the joint part as a whole. There is a disadvantage in that, there is a problem that the unit member is frequently repaired due to changes in external temperature and impact.

Therefore, an object of the present invention is to simplify the series of manufacturing process to form a whole round tube by using artificial marble plate material having a wide range of material selection, low price and excellent processability by supplying various patterns, and whole It is to provide a manufacturing method of artificial marble tube which enables the tube body to express a more beautiful and high quality as a sophisticated product having the same texture.

The above object is to prepare an artificial marble plate cut to a predetermined width and length; A heating step of plastic deformation by applying heat to the artificial marble sheet; Forming a tubular body by inserting the artificial marble sheet in the plastically deformed state into the inner diameter of the circular jig and inserting the same; Cooling the tube inserted into the circular jig lower than room temperature to separate the contracted tube from the circular jig; Pressing a wedge into an inner diameter of the separated tube to open abutting portion, and cutting the wedge into a straight surface; Separating the wedges inserted into the tube and applying an adhesive to the cut portion, and then pressing and curing the adhesive portion to be in close proximity or contact with a band and a block; And, after removing the band and the block is achieved by a method of manufacturing an artificial marble tube, characterized in that it comprises the step of smooth polishing the joint of the hardened joint of the tube.

In addition, another embodiment of the present invention in the process of forming a pipe by inserting, hardening and separating the plastically deformed artificial marble plate to the circular jig, the guide is installed in the circular jig inlet to facilitate the insertion of artificial marble plate Hot water or cooling water is circulated around the circular jig, thereby making it easier to insert and separate the artificial marble plate body, thereby achieving the productivity of the artificial marble tube, characterized in that the productivity can be improved.
