Abstract

PROBLEM TO BE SOLVED: To easily provide a lightweight and waveless ceiling board with high design efficiency and having good quality. SOLUTION: Frame members 2 having grooves in the end faces are mounted to both ends of a substrate 1 by directing the grooves to the outsides, a honeycomb core 3 laminating a sheet on at least one side is mounted between the frame members 2 by directing the sheet non-laminated surface to the substrate side, and it is coated with a facing member 4 continued from the groove of one frame member 2 to the surface of the substrate 1 and the groove of the other frame member 2 to stick. Therefore, warp is made in accordance with humidity variations while holding strength sufficiently as the ceiling board to make it possible to prevent the occurrence of waves in the whole ceiling board and, at the same time, corners of the frame members can be formed into the curved surfaces, or the ceiling board can flexibly correspond to an optional design to be required without being controlled over the sectional design.

A thin wooden board of about 7 mm is used. The frame material 2 is made of lumber, particle board, LVL, OSB, or the like. The honeycomb core 3 has a sheet 3a laminated on both sides. The material of the honeycomb core 3 may be cardboard or aluminum. The reason for using the laminated sheet 3a is to facilitate attachment to the substrate 1. The material of the sheet 3a may be the same as the material of the honeycomb core 3. However, it is preferable to use a moisture-proof material such as polyethylene because moisture from behind the ceiling can be blocked to further prevent warpage. The attachment to the substrate 1 may be applied to the entire surface with an adhesive, but there is also a method of attaching to the frame 2 by a tucker 5 without using an adhesive.

結するためのものである。A frame member 2 is attached to both ends of the substrate 1 with an adhesive. The adhesive may be a conventional one in which an emulsion type such as a vinyl acetate resin type, an EVA type or an acrylic resin type is used alone, or a thermosetting type such as a urea resin or a melamine resin is mixed. The honeycomb core 3 on which the sheet 3 a is laminated is attached between the frame members 2. Installation is honeycomb core 3
The same adhesive as above may be applied to the back sheet 3a and adhered thereto, or may be fixed to the frame member 2 with the tucker 5, but the method of stopping with the tucker 5 is quick and reliable. A groove 2a is formed at an end of the frame member 2. When the ceiling plate is constructed, the groove 2a is for fitting a metal fitting or a small nut to connect the ceiling plates together.

As the decorative material 4, a vinyl chloride resin sheet or a printed decorative paper is used, and the same adhesive is applied, and the decorative material 4 is continuously coated and adhered by a wrapping machine. Before attaching the decorative material 4, the corners of the frame material 2 may be processed into an arbitrary shape using a molding machine or the like to form a ceiling plate having a desired end shape.

る。According to the present invention, the following effects can be obtained. Since a honeycomb core is used instead of reinforcement,
It is possible to prevent the ceiling board from waving due to a change in humidity while maintaining the strength of the ceiling board sufficiently. A decorative material that is continuous from the groove of the frame material to the groove of the other frame material is applied by a wrapping machine etc. so as to cover the surface of the substrate, so the cross-sectional design is not limited and the corners of the frame material are formed into curved surfaces It can respond flexibly to any design you want or want. Since the honeycomb core is used in place of the conventional reinforcing material made of wood, the weight is extremely reduced and no labor is required for construction. Further, after the construction, the load on the mounting portion due to the weight of the ceiling plate can be reduced, and the hanging of the ceiling plate can be prevented. Since a honeycomb core in which sheets are laminated on at least one side is used, a pin can be easily attached to a frame material by a tucker or the like at the time of manufacture, and the frame can be easily manufactured. Also,
When a honeycomb core in which sheets are laminated on both sides is used, adhesion to the substrate can be performed on the surface and peeling can be reduced.
