Description

[Detailed explanation of the invention] This invention is a mounting structure for the surrounding edge, more specifically,
This invention relates to a mounting structure for a circumferential edge that is mainly installed at a corner between a wall panel and a ceiling panel in a room with high humidity such as a bathroom.

As shown in FIG. 1 or 2, conventional circumferential edges of this type include a circumferential edge 15 having a substantially U-shaped cross section that fits into the circumferential edge of the ceiling panel 2, and a circumferential edge 15 that fits on the circumferential edge of the ceiling panel 2, and a circumferential edge 15 that fits on the circumferential edge of the ceiling panel 2. A surrounding edge main body 17 that fits into the provided surrounding edge receiver 16 is provided, and the surrounding edge receiver 16
There was a surrounding edge that held the peripheral edge of the ceiling panel 2 between the surrounding edge body 17 and the surrounding edge main body 17, but both of them were designed to prevent water droplets attached to the lower surface of the ceiling panel 2 from getting around to the upper surface of the ceiling panel 2 and the back surface of the wall panel 1. This was not something that could be prevented, and the moisture sometimes corroded ceiling and wall structural materials.

The present invention was developed in view of the above points, and its main purpose is to prevent water droplets attached to the bottom surface of the ceiling panel and indoor water vapor from entering the top surface of the ceiling panel and the back surface of the wall panel. It's about doing.

Hereinafter, embodiments of the present invention will be described based on the drawings. As shown in FIG.
are arranged over the entire length of the corner portion in the longitudinal direction. A pair of projecting pieces 9a, 9 are provided on the lower surface of the surrounding edge receiver 3.
b and the hanging piece 11 protrude, a groove 5 is formed between the protruding pieces 9a and 9b, and a recess 12 is formed between the protruding piece 9a and the hanging piece 11 closer to the wall panel 1. A protrusion 4 projecting upward from the circumferential edge main body 6 is fitted into the groove 5, and the upper end of the wall panel 1 is accommodated in the recess 12. The surrounding edge main body 6 is disposed at the corner between the wall panel 1 and the ceiling panel 2 over the entire length in the longitudinal direction. A wall-side elastic piece 7 made of a soft material is formed in close contact with the circumferential edge main body 6 over the entire length in the longitudinal direction, and at one end on the ceiling panel 2 side, a wall-side elastic piece 7 is formed on the lower surface of the circumferential edge of the ceiling panel 2 over the entire longitudinal length of the circumferential edge main body 6. A ceiling elastic piece 8 is formed of a soft material in close contact with each other. These wall-side elastic pieces 7 and ceiling-side elastic pieces 8 are closely connected to the surface of the wall panel 1 and the surface of the ceiling panel 2, respectively, and extend from both ends of the edge 6 to the wall panel 1 and the ceiling panel 2.
This prevents water from entering the corner between the By the way, the concave groove 5 of the surrounding edge receiver 3
A serrated portion 13 is formed along the vertical direction on the inner wall of the groove 5, and a serrated portion 14 is formed along the vertical direction on the surface of the protrusion 4 that fits into the groove 5. That is, when the circumferential edge main body 6 is fitted into the circumferential edge receiver 3, the serrated portions 13, 14 of the concave groove 5 and the protrusion 4 are formed.
This ensures that the two parts mesh together to ensure a secure connection so that they do not come off. On the other hand, wall panel 1
A soft packing 10 is provided on the side surface of the protruding piece 9a on the side of the recess 12, and the distance between the packing 10 of the recess 12 and the hanging piece 11 is set to be slightly larger than the thickness of the wall panel 1 (0.1~ 0.2 mm), and by fitting the upper end of the wall panel 1 into the recess 12, the gasket 10 is brought into pressure contact with the surface of the wall panel 1. However, by inserting the protrusion 4 into the groove 5, the protrusions 9a and 9b are pressed and bent, so that the packing 10 can be brought into further pressure contact with the surface of the wall panel 1 to improve sealing performance.

As described above, the present invention has a surrounding edge holder that extends between a hanging piece that hangs down along the back side of a wall panel, and a hanging piece that is approximately parallel to the hanging piece and spaced apart from each other, and that extends between the indoor side surface of the upper part of the wall panel and the end face of the ceiling panel. A pair of hanging protrusions are formed in an integrally extending shape,
The upper part of the wall panel is held between the outer surface of the wall panel-side projecting piece of both projecting pieces and the hanging piece, and a gasket is provided on the outer surface of the projecting piece to press against the indoor side surface of the wall panel. A protrusion that fits into the groove formed between both protrusions is integrally provided on the upper surface of the circumferential edge body, and from the end of the circumferential edge body on the wall panel side, the circumferential edge body is attached to the indoor side surface of the upper part of the wall panel. A wall-side elastic piece that comes into elastic contact over the entire length of the rim body is integrally extended, and a ceiling elastic piece that comes into elastic contact over the entire length of the rim body extends from the end of the surrounding edge body on the ceiling panel side to the lower surface of the ceiling panel periphery. Since the elastic piece on the wall side and the elastic piece on the ceiling side can prevent water from entering the corner between the wall panel and the ceiling panel, the gasket provided on one side of the protruding piece can prevent water from entering the back side of the wall panel. Waterproofing can be guaranteed, and double sealing is used.
This has the advantage that the wall structural material on the back side of the wall panel and the ceiling structural material on the top side of the ceiling panel can be prevented from being corroded by moisture from the room.
