Description

[Detailed Description of the Invention] The present invention relates to a decorative ceiling material that is lightweight and can be firmly fixed to a ceiling surface.

Conventionally, this type of ceiling material was used, for example, in 1973.
-There are decorative ceiling materials that can add three-dimensional decoration to the ceiling without modifying the existing ceiling, as shown in Publication No. 138617, but they are generally manufactured in one piece from synthetic resin, wood, metal, etc. This made it heavy, which was a fatal drawback in terms of construction as a decorative ceiling material that was attached directly to the ceiling surface.

Therefore, in order to reduce the weight of these decorative ceiling materials, the thickness of the flat plate parts and protruding decorative edges that make up the decorative ceiling materials is made thinner, which reduces the strength of the decorative ceiling materials themselves and reduces the nail holding power as well. However, it cannot be firmly attached to the ceiling. Furthermore, even if it is attached to the ceiling, it has the disadvantage that it may sag and deform during long-term use, creating a gap between it and the ceiling.

The present invention has been made to solve such drawbacks, and is made to protrude the outer periphery of the back surface of a synthetic resin foam molded product having an uneven decorative surface on the surface.
The present invention relates to a decorative ceiling material in which a required number of mounting pieces of wood are embedded and fixed in a portion of the back surface other than the outer periphery of the back surface of the molded body so as to be on the same level as the outer periphery of the back surface.

The present invention will be explained in detail below with reference to Examples.

1 in the figure is a synthetic resin foam molded product, and polyurethane resin is most commonly used in terms of moldability and strength, but other synthetic resins with foaming properties such as polyester resin and polyvinyl chloride resin are also used. Can be used.

Although the expansion ratio varies somewhat depending on the synthetic resin used, it is preferably about 4 times from the viewpoint of strength and weight. Reference numeral 3 is a piece of wood for attachment, which is fixed to a part of the back surface other than the land surface outer periphery 2 at the same level as the outer periphery 2 of the back surface when the synthetic resin is foam-molded.

As shown in FIG. 1, the decorative ceiling according to the present invention is directly fixed to an existing ceiling surface with nails 4 or screws via mounting wooden pieces 3.

At this time, the construction will be easier if a nailing hole is provided in advance on the wooden piece 3 for attachment so that nailing can be done accurately.

Furthermore, since the decorative ceiling material of the present invention is based on a synthetic resin foam molding, it can be considerably lightweight, but in order to further reduce the weight and raw material costs, the foam molding material is used as shown in Figures 2 and 3. The space portion 5 may be formed in a desired portion. If a decorative board 6 is bonded to the space 5, it is possible to provide a decorative ceiling material that is lighter in weight and has a greater variety.

Since the present invention has the above-mentioned configuration, when a decorative ceiling is fixed to an existing ceiling surface with nails or screws, it is directly fixed to the ceiling surface via a piece of wood for attachment, so conventionally this type of decorative ceiling Compared to wood, it is much easier to attach nails and screws without having to fix the outer periphery of the ceiling material, and even if the ceiling surface is slightly uneven, the space formed between the pieces of wood for installation can be easily fixed. It has a good appearance and can be firmly attached to the ceiling, and also prevents deformation of the outer periphery of the decorative ceiling material due to its own weight. Even after long-term use, the outer periphery of the decorative ceiling material and the There is no gap between it and the ceiling surface.

Claims (1)

[Scope of utility model registration request] A piece of wood for attachment is attached to a part of the back surface other than the outer periphery of the molded product so that the outer periphery of the back surface of the synthetic resin foam molded product having an uneven decorative surface protrudes and is at the same level as the outer periphery of the outer back surface. Decorative ceiling material made by embedding and fixing the required number of materials.
