Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a lattice-shaped ceiling using existing T-bars.

[Background technology]

Conventionally, the cross-sectional shape of the system ceiling was an inverted T.
Hang the letter-shaped T-bars with hanging bolts and assemble them in a lattice pattern.
In each lattice space, ceiling material is placed on the lower flange of the T-bar. In such a system ceiling, the configuration shown in FIG. 1 is adopted when it is desired to change to a lattice ceiling after construction to improve decorativeness.

In FIG. 1, reference numeral 1 denotes a T-bar, which is suspended from a beam (not shown) or the like with hanging bolts 2 and assembled in a lattice shape. The T-bar 1 and the hanging bolt 2 are joined by a hanger 3. A ceiling material 4 is fitted into each lattice space formed by the T-bars 1 and placed on the lower edge flange 1a of the T-bars 1. The louvers 5 that form the lattice ceiling are made of wood and are attached to hanging bolts 6 that pass through the ceiling material 4, or are attached to the T-bar 1.
A hook 7 is attached to the frame, and it is suspended by a wire 8.

However, since the louver 5 is installed below the existing ceiling material 4 in this way, it is difficult to secure the ceiling height when the existing ceiling height is low. Furthermore, the hanging bolts 6 and wires 8 must be constructed separately, making the construction complicated.

[Purpose of invention]

The purpose of this invention is to provide a ceiling that can be easily constructed using existing T-bars and that can ensure ceiling height.

[Disclosure of invention]

The ceiling of this invention has a downward lip groove-shaped louver body that covers the vertical piece of the T-bar, and the louver body is attached by sandwiching the vertical piece of the T-bar with a retaining spring provided on the inner surface of the web. This is what I did.

An embodiment of this invention is shown in FIGS. 2 to 6. In other words, this ceiling is constructed by placing the downward lip groove-shaped louver body 9 over the vertical piece 1b of the existing T-bar 1, and using the retaining spring 10 provided on the inner surface of the web of the louver body 9, the wide upper edge of the vertical piece 1b 1c is sandwiched between them. The T-bar 1 is suspended by hanging bolts 2 as in the example shown in FIG. Remove ceiling material 4. The louver main body 9 is made of a steel plate, and is formed to have approximately the same width as the T-bar 1. The holding springs 10 are provided at both ends of the louver body 9. The retaining spring 10 may be provided in the middle of the louver body 9 in the longitudinal direction as appropriate. A notch 11 through which the hanger 3 of the hanging bolt 2 passes is appropriately provided on the web surface of the louver body 9. Further, when the louver main body 9 is provided continuously beyond the intersection of the T-bars 1, a notch (not shown) through which the vertical piece portion 1b of the T-bar 1 is inserted is provided in both flange portions.

In this way, the louver body 9 only needs to be placed over the existing T-bar 1 and held between the retaining springs 10, so construction is easy. Also, the louver body 9 is T
Since it has approximately the same width as the bar 1, it looks like a single square bar and the appearance is improved. Furthermore, since the louver body 9 is placed over the T-bar 1, the same ceiling height as the existing ceiling height can be ensured.

[Effect of idea]

The ceiling of this invention can be easily constructed using existing T-bars, and has the effect of ensuring the ceiling height.
