Description

[Detailed Description of the Invention] The present invention relates to a grid-shaped ceiling louver installed below a ceiling lighting fixture.

For this type of louver, it is impossible to configure the entire desired area with a single louver because it is necessary to easily remove it during construction and when inspecting or replacing lighting equipment or other equipment. A construction method is used in which many louvers are connected using connecting materials.

In the conventional construction method, the connecting member is a single vertical board or a grid of several vertical and horizontal boards, and the louver is connected to the connecting member to form a ceiling louver. Since the area occupied by the connecting material is smaller than that of the louvers, the number of louvers is large, which has the drawback of requiring a large amount of construction time. Further, if the vertical plate and the horizontal plate have an I-shaped cross section (single material) and are not thick, it is difficult to mold both plates straight, and the louver is easily bent when assembled.

This proposal aims to improve these shortcomings by making the louver corresponding to the above-mentioned connecting material approximately 1 to 5 times the area of the other louvers connected to the louver, and pre-aligning the louver corresponding to the connecting material in the vertical direction. These louvers are connected and attached to the ceiling, and other louvers are connected adjacent to the louver to simplify construction and shorten the construction time.

In other words, a lattice-like louver A is formed by vertical ribs and horizontal ribs that are both approximately shaped in cross section at predetermined intervals and intersected at right angles, and longitudinal ribs and horizontal ribs that are both approximately shaped in cross section are arranged at predetermined intervals. The area ratio of the louvers A and louver B is about 1:1 to about 5:1, and the louvers A are connected to each other by vertical ribs and horizontal ribs. The louvers A and louver B are connected in the horizontal direction by the intersection of the horizontal ribs of louver B and the vertical ribs of louver A, and the louvers A and B are connected in the horizontal direction. This is a ceiling louver arranged vertically.

The feature of this project is that the louver A corresponds to the conventional connecting material.
The area of the louver B is about 1 to 5 times that of other louvers B. When the construction area is the same compared to the conventional connecting material composed of 1 to 3 vertical plates, the number of louvers A is reduced, the lower end surface of the louver A is easily leveled, and the construction time is reduced. can be shortened.

Louva A consists of about 10 to 20 vertical ribs,
It consists of about 10 to 40 horizontal ribs.

The louvers A and louvers B are constructed by intersecting vertical ribs with a cut half the height from the top or bottom surface and horizontal ribs with a cut half the height from the bottom or top surface at the cut point. be done. The louvers A and the louvers B are arranged vertically,
The louvers A and louvers B are arranged alternately in the horizontal direction. The louvers A are connected by intersecting a part or all of the vertical ribs of one of the adjacent louvers with the horizontal ribs of the other louver. Louver A and louver B are connected by crossing some or all of the horizontal ribs of louver B with the vertical ribs of louver A. The louvers B may be connected in the same way as the louvers A by intersecting some or all of the vertical ribs of one adjacent louver with the horizontal ribs of the other louver, or a part of one louver. Alternatively, all the vertical ribs may be brought into contact with the horizontal ribs of the other louver, or some or all of the vertical ribs of one louver and the other louver may be brought into contact with each other and connected.

The vertical ribs and the horizontal ribs may have a cross-section shaped like a type, a U-shape, a V-shape, or the like.
