Description

[Detailed description of the invention] This invention creates a ceiling surface with excellent waterproofness by laminating a ceiling finishing material and a board, and pasting a waterproof sheet on the top surface of the board with a protruding part on the edge. This invention relates to a ceiling panel that can be formed simply and quickly.

When forming on the ceiling surface, for example, to prevent condensed water generated in the attic from dripping or adhering to the ceiling and staining the indoor ceiling surface, wall surface, etc.
Prior to installing the ceiling board, it is common practice to apply a waterproof sheet over the entire surface of the ceiling base material or attach waterproof tape to the edge surface of the ceiling board at the joint. But the sheet that takes,
Pasting the tape requires work in an upward position, resulting in poor work efficiency.Especially in the former case, the sheet is wide, making it difficult to handle and requiring a great deal of effort to waterproof the ceiling surface. It had the disadvantage of poor construction efficiency.

The present invention aims to provide a ceiling panel that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

1 and 2, the ceiling panel 1 of the present invention is constructed by laminating a substrate 2 and a ceiling finishing material 3 and pasting a waterproof sheet 4 on the upper surface of the substrate 2 facing the attic. Relatively thin rectangular plywood is used, and the ceiling finishing material 3 is gypsum board 5, which has excellent fire resistance and water resistance, and an overhang 7 of the board 2 can be formed on two sides sandwiching one corner. Since the substrate 2 is slightly smaller than the substrate 2, the substrate 2 is attached to the top surface of the ceiling finishing material 3 using an adhesive or the like to cover the top surface of the ceiling finishing board 2, and both are made of a flat plate material. As a result, the ceiling panel 1 forms a flat plate material having a total thickness by laminating the layers. In addition, the board 2 is used as a ceiling base material 3.
2 of the ceiling base material 3 by aligning and attaching the one corner part and the diagonal corner part to the
The overhanging portion 7 is formed on the side so as to continuously protrude from the edge with the same width. Moreover, its lower surface, including the side surfaces and the overhanging portion 7, is covered with a patterned paper 6 to give a decorative finish. The waterproof sheet 4 is made of a synthetic resin sheet with excellent waterproof properties such as nylon or polyester, and has an overlapping protruding portion 10 over the entire surface of the upper surface of the substrate 2 and at the edge on the side of the overhanging portion 7. It is pasted.

As shown in FIG. 2, the ceiling panel 1 may have one overhang 7 interposed between the ceiling panels 1, and the overhang 7 may form, for example, a grid-like joint 9. At the same time, the protruding portions 10 of the waterproof sheets 4 provided on the overhanging portions 7 are overlapped with the waterproof sheets 4 on the opposite edges of the adjacent ceiling panels 1, and each ceiling panel 1 is sequentially placed side by side with the outside edge. By fixing screws to 12, a ceiling surface can be formed, and at that time, the ceiling panel 1 is attached to the edge 12 via the waterproof sheet 4, and the waterproof sheet 4 overlaps to ensure waterproofing of the ceiling surface.

In Figures 3 and 4, a waterproof sheet 4 is pasted on each side of a substrate 2 on a ceiling panel 1 with a protruding portion 10, and the protruding portions 10 of adjacent ceiling panels 1 and 1 are attached in a zigzag shape. Another embodiment of the present invention is shown in which the ceiling panels 1 are stacked one on top of the other and are sequentially attached to the roof edge 12 to improve the waterproofness of the ceiling surface and patterned paper 6 is pasted only on the lower surface of the plasterboard 5. Incidentally, the protruding portion 10 of the ceiling panel 1 can be cut out as appropriate, and the ceiling panel 1 can be attached in the same manner as shown in FIG. 2.

As mentioned above, the ceiling panel of the present invention has a structure in which the ceiling finishing material and the substrate are laminated, and a waterproof sheet is pasted on the top surface of the substrate.As a result, the ceiling surface can be waterproofed with the waterproof sheet at the same time as the ceiling panel is installed. This makes it possible to easily and quickly form a ceiling surface with excellent waterproof properties, reducing labor and greatly increasing work efficiency compared to the conventional method of pre-installing waterproof sheets or tape on the edges. It becomes possible to improve the performance. Further, since the waterproof sheet is attached to the substrate with a protruding portion, the waterproof sheet overlaps at the joint portion of adjacent ceiling panels, thereby improving the waterproofness of the ceiling surface. In addition, even if the ceiling finishing material is made of easily breakable materials such as gypsum board, plywood is used to reinforce the material to prevent cracking and make it easier to handle, and the patterned paper not only improves the aesthetics but also makes it easier to handle the ceiling finishing material. Helps improve strength. Furthermore, since the substrate is provided with an overhang, by arranging the substrates in contact with each other, it is possible to accurately and easily form the joint portion of the ceiling board.
