Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, fitting grooves 2 which are open on the upper surface and both sides of the hanging core plate 1 are recessed at multiple locations in the longitudinal direction, and fitting grooves 2 that are open on the lower surface and both sides of the hanging core plate 3 are provided. A decorative plate 5 having a vertical width shorter than the vertical width of the hanging core plate 1 is provided on both sides between the fitting grooves 2 of the hanging core plate 1. Paste it on both sides between the fitting grooves 4 of the core plate 3, then cross the hanging core plate 1 and the hanging core plate 3, and fit the fitting grooves 4 into the fitting grooves 2 from above. The purpose is to provide a method for manufacturing a ceiling lattice which is characterized by mating and can be easily manufactured without the need for troublesome processing.

Conventionally, when manufacturing ceiling gratings by hand, it takes a long time and is expensive, and when manufacturing them with a radial saw cutter, the cutter has to be cut every time the cross-sectional shape of the ceiling grating is changed. It was necessary to perform thickness adjustment and pitch adjustment, which was also time-consuming.

As mentioned above, the present invention has been made with the aim of reducing the labor involved in manufacturing a ceiling lattice, and will be described in detail below with reference to Examples.

A plurality of fitting grooves 2 as shown in FIG. 2 are provided at regular intervals in the upper part of the hanging core plate 3, and fitting grooves 4 as shown in FIG. 3 are provided in the lower part of the hanging core plate 3. A plurality of grooves are provided at the same intervals as the grooves 2.

The decorative plate 5 is made by cutting both ends of a decorative blank plate 6 molded with decorative unevenness as shown in FIG. 4 at an angle of 45 degrees as shown in FIG. It is formed with a trapezoidal cross section.

The upper and lower middle parts of the decorative plate 5 are shorter than the upper and lower middle parts of the hanging core material 1, and the hooks are larger than the upper and lower middle parts of the hanging core board 3. The width is the same as the width between the fitting grooves 2 and between the fitting grooves 4.

The long sides of this decorative plate 5 are pasted on both sides of the hanging core plate 1 between the fitting grooves 2 adjacent to each other by laminating and pressing as shown in FIG.

Similarly, as shown in FIG. 7, the decorative plates 5 are pasted on both sides of the core plate 3 between the adjacent fitting grooves 4 by lamination and pressing.

After that, the fitting groove 2 of the hanging core plate 1 is fitted into the fitting groove 4 of the hanging core plate 3 from above, so that the hanging core plate 1 and the hanging core plate 3 intersect at right angles.

In this way, the decorative plate 5 of the hanging core material 1 at the intersecting portion and the decorative plate 5 of the hanging core board 3 are connected to each other on the inclined abutting surfaces 7,
7 will be interviewed as shown in Figure 8.

In the same way, the hanging core plates 1 and the hanging core plates 3 are cross-connected in all directions to form a ceiling lattice as shown in Figure 1. It is to be hung.

Here, the dimension from the groove bottom of the fitting groove 2 to the lower surface of the suspension core plate 1 and the groove depth of the fitted groove 4 are the same dimension, and the lower surface of the suspension core plate 1 and the hanging core plate 1 are the same size. It is flush with the bottom surface.

Alternatively, the lower end of the hanging core plate 1 and the lower end of the decorative plate 5 may be placed at almost the same level as shown in FIG. This means that ceiling lattices with various cross-sectional shapes can be formed by positioning the ceiling grids in different shapes.

As mentioned above, in the present invention, the decorative plates are attached to both sides of the hanging core board, and the hangings are attached to both sides of the hanging core board, so decorations can be applied to the ceiling lattice by hand or by radial cutting. There is no need to form the core plate, and it is easy to attach it by just working.Moreover, when attaching the core plate for hanging the decorative plate or hanging the core plate, you can move the position up or down or change the thickness of the core plate. It is possible to form ceiling lattices with various cross-sectional shapes simply by doing the following, and it is possible to easily manufacture ceiling lattices with different designs.

Furthermore, since the vertical width of the hanging core plate is made larger than the vertical width of the decorative plate, the upper part of the hanging core plate can be made to protrude beyond the decorative plate and can be used for mounting a hanging book.
