DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. FIG. 1 is an overall perspective view of a log decorative plate according to a first embodiment of the present invention.
Is a partially omitted cross-sectional view of the log decorative plate, and FIG. 3 is an explanatory view of an assembly process of the log decorative plate. 4 is a partially omitted cross-sectional view of a modified example of the log decorative plate of the first embodiment, FIG. 5 is an overall perspective view of the modified example, and FIG. 6 is another modified example of the log decorative plate of the first embodiment. 3 is a partially omitted sectional view of FIG. FIG. 7 is an overall perspective view of a log decorative plate according to a second embodiment of the present invention, and FIGS. 8 and 9 are assembly process explanatory diagrams of the log decorative plate.

[First Embodiment] In FIGS. 1 to 3, the reference numeral 1 designates a short log material of the same size, which is obtained by shortening and thinning a thinned wood material, and forming a row around a log decorative plate material. Has been established. These logs 1.1 are connected by dowels 12.12 ... and dowels are connected to each other. A slit 11 is formed (see FIG. 3).
reference).

In the figure, what is indicated by the reference numeral 2 is a reinforcing plate made of a plywood, which is a slit of a log 1, 1,...
.. Are fitted. Further, plate-shaped decorative materials 41 are arranged on the upper and lower surfaces of the reinforcing plate material 2, and a space A (see FIG. 2) between the decorative material 41 and the surrounding log materials 1.1,. ) Is injected with a cold-setting adhesive 3 (see FIG. 1) mainly composed of an epoxy resin mixed with wood chips.

The adhesive 3 fixes the plate-like decorative material 41 above and below the reinforcing plate 2 and at the same time, the reinforcing plate 2 and the logs 1.1, and the adjacent logs 1.1,.・ They are securely joined and fixed to each other to obtain a log decoration plate material with sufficient strength. In FIG. 2, the adhesive 3 is not shown to show the space A.

As described above, in the log decorative plate of the present embodiment, the logs 1, 1,... Are connected and fixed not only by the dowel joint and the adhesive but also by the fitting with the reinforcing plate 2. Therefore, sufficient strength can be ensured, and there is no fear that the surrounding log material will fall off unlike the conventional product.

In the above embodiment, the plate-like decorative materials 41 are arranged on the upper and lower sides of the reinforcing plate 2 so as to expose the surface. However, as shown in FIG. Are arranged in a shorter dimension than the log material 1 of the above, and these log decoration materials 42, 42,... And the surrounding log materials 1, 1,.
If the adhesive 3 is poured into the space A between the two, it is also possible to obtain a log decorative plate made of only a log as shown in FIG.

Further, instead of the plate-shaped decorative material 41 and the log decorative material 42, for example, a branched natural tree is disposed on the reinforcing plate 2 in a lying state, and the adhesive 3 is poured into the space A. , And when shaving the surface of the solidified adhesive 3,
If the natural tree with branches is cut out, a natural tree pattern with branches can be displayed on the surface of the plate material, and the decorativeness can be further improved.

As described above, in the log decorative plate of the present invention, the type, shape, number, position, and the like of the decorative materials 41 and 42 provided on the adhesive portions on the upper and lower surfaces of the reinforcing plate 2 are simply changed. The surface decoration can be easily changed with this, and the decoration variety is excellent.

Furthermore, in the above embodiment, the log materials 1.1
················································································································ As shown in FIG. Notched 11 ・ 11 ・ ・ ・ ・
Furthermore, if the separate reinforcing plate members 2 are fitted and connected, it is possible to easily provide a log decorative plate member having a large area without a decrease in strength. 4 and 6, the illustration of the adhesive 3 is omitted to show the space A.

[Second Embodiment] A second embodiment shown in FIGS.
The log decorative plate material according to the embodiment is such that log materials 1, 1,... Having a slit 11 formed in the middle of the peripheral side surface are arranged in a circular shape by dowel joints, and these log materials 1, 1,.・ Slice 11 ・ 11
A circular reinforcing plate 2 is fitted to.

On the upper and lower surfaces of the reinforcing plate 2, frames 51, 51 which define a space B inside are disposed, and the upper frame 51 and surrounding log materials 1.1,. .Space A between
Only in FIG. 8 (see FIG. 8), a cold-setting adhesive 3 (see FIG. 9) mainly composed of an epoxy resin mixed with wood chips is injected, and the decorative board 5 is further covered so as to cover the frames 51.・

As described above, in the log decorative plate of the present embodiment, the reinforcing plate 2 and the log 1, 1... ···························································································································· ···

In the present embodiment, the adhesive 3 is not injected into the lower surface of the reinforcing plate 2 in order to further reduce the manufacturing cost and reduce the weight. An adhesive may be injected into the plate, and various design changes are possible in consideration of the strength and decorativeness of the decorative plate material.

In this embodiment, as shown in FIG. 9, after the frames 51 are arranged on the upper and lower surfaces of the reinforcing plate 2, the adhesive 3 is injected into the space A to make the decorative plate 5. 5 is attached, but the log decorative plate material according to the present invention is, of course, not limited to this production order. The frame body 51 and the decorative plate material 5 are joined in advance, and this is 2, the adhesive 3 may be injected into the space A for production. In this way, it is possible to easily match the upper end surface level of the surrounding log materials 1, 1... With the upper surface level of the decorative plate material 5, and to easily make a log decorative plate material having a flush surface. can get.

[0020]

As described above in the embodiment, in the log decorative plate according to the present invention, the logs arranged in the periphery are fitted and connected by the reinforcing plate and the adhesive Since the reinforcing plate material and each log material and the adjacent log material are bonded and fixed to each other, sufficient strength can be secured without complicating the structure, and the surrounding log material can be secured as in the conventional product. There is no worry that it will easily fall off.

Further, if necessary, the surface decoration can be easily changed by changing the decorative material disposed on the surface of the adhesive portion with the surface exposed, or the decorative plate material disposed on the adhesive portion with the surface covered. Therefore, the log decorative plate material of the present invention is very excellent in decorative diversity, and can be widely applied, for example, as a table top plate material or a decorative wall material of a building.
