Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a corner part of a ceiling, particularly an edge around a ceiling, which is suitable for rooms where fine dust is averse, such as in laboratories, pharmaceuticals, food products, precision machinery factories, etc.

[Conventional technology]

Conventional ceiling edges have a rectangular cross section, and the corners only abut each other, so fine dust tends to adhere to the corners and edges of the ceiling, making cleaning extremely difficult.

[Purpose of invention]

An object of the present invention is to provide a circumferential edge that is formed into a curved surface, and in particular has separate corner members to prevent the adhesion of fine dust and that can be easily cleaned.

[Structure of the idea]

The present invention consists of an outer surface and a spherical inner surface formed by connecting a top surface and two vertical surfaces displaced by 90 degrees from each other through an inclined surface, and three connections formed at an angle of 90 degrees to each other. It is composed of a corner member consisting of a rim, and a circumferential edge member having a curved surface that conforms to the spherical inner surface, and protrusions are integrally provided on the back side of both left and right edges of the circumferential edge member, and the protrusions are displaced 90 degrees from each other at the tip of the protrusions. This is the edge around the ceiling with an integral contact strip.

〔Example〕

In the figure, reference numeral 1 indicates a corner member, and reference numeral 2 indicates a circumferential edge member, both of which are molded from synthetic resin. , 8 and 9, connecting edges 10, 11, 12 are provided with an outer surface 1a and a spherical inner surface 1b, and are formed at an angle of 90 degrees to each other.
The circumferential edge member 2 has a curved surface 13 that fits the spherical inner surface 1b of the corner member 1, and protrusions 14 and 15 are integrally provided on the back side of both left and right edges, and the ends of the protrusions 14 and 15 are arranged at 90 degrees each other. Contact strips 16, 17 are provided which are displaced by a degree.

[Effect]

As shown in FIG. 3, a corner member 1 is applied to a ceiling corner, and surrounding edge members 2 are connected to the corner member 2 on the left and right sides. Further, when the surrounding edge member 2 is connected to the connecting edge 12 at the lower end of the corner member 1 as shown in FIG. 4, it can be used as an inside corner member. In this case, a filler 19 is applied to the gap between the left and right sides and the exterior wall material 18.

[Effect of idea]

In the present invention, when the corner members and surrounding edge members are attached, the ceiling and corner portions are all curved and there are no corners, which prevents fine dust from adhering and is extremely easy to clean. Additionally, the connection operations at the corners can be performed quickly.
