Ceiling panel apparatus and method of manufacturing the same

A method of manufacturing a ceiling panel apparatus, the method comprising:

• a first layer forming step for forming a first layer substantially having a rectangular plate shape and made of a first material;
• and
• a reinforcing member forming step (for forming one or more reinforcing members substantially having a rod shape, made of a second material, and provided in a diagonal direction on an upper surface of the first layer to prevent sagging,
• wherein the reinforcing member forming step comprises:
• a preparation step for preparing three reinforcing members having a first length;
• a cutting step for using one of the three reinforcing members as a first reinforcing member and cutting the other two to prepare two second reinforcing members having a second length and two third reinforcing members having a third length;
• and
• a disposition step for disposing the two second reinforcing member and the two third reinforcing member at both sides of the first reinforcing member.

A ceiling panel apparatus comprising:

• a base substantially having a rectangular plate shape and made of a first material;
• and
• one or more reinforcing members substantially having a rod shape, made of a second material, and provided in the base to prevent sagging of the base,
• wherein the base is a square-shaped plate or panel with horizontal and vertical sides of equal length,
• wherein the one or more reinforcing members are disposed in a diagonal direction of the base, extend at both ends to an overlap region where an edge of the base overlaps a ceiling support, and comprise:
• a first reinforcing member mounted in the base to extend a first length;
• at least one second reinforcing member mounted in the base to extend a second length less than the first length and disposed at a position spaced apart from the first reinforcing member by a first distance;
• and
• at least one third reinforcing member mounted in the base to extend a third length less than the second length and disposed at a position spaced apart from the at least one second reinforcing member by a second distance,
• wherein the first material is an eco-friendly material comprising a cork material made by selecting at least one of oak, cypress, cork oak, and combinations thereof,
• wherein the second material is bamboo,
• wherein the one or more reinforcing members have a circular rod shape, and
• wherein the bamboo has a grain pattern extending along a longitudinal direction of the one or more reinforcing members on outer circumferential surfaces of the one or more reinforcing members.
