Description

[Detailed description of the invention] This invention relates to a paulownia laminated material formed by joining rope boards and paulownia particle boards alternately in the width direction.

Paulownia particle board formed using leftover paulownia wood has already been known.

This paulownia particle board is made by crushing small pieces of paulownia wood and waste wood into fine pieces, then adding 10% urea adhesive to the dried pieces.
This is then compressed into a board using a cold press and then a hot press.As this uses only paulownia wood as its raw material, it has excellent moisture and heat resistance, as well as soundproofing properties. good.

In addition, it has the advantage of being easy to process because a product with the same specific gravity as paulownia wood can be obtained, but on the other hand, as is the case with particle boards in general, this paulownia particle board also has the disadvantage of being susceptible to sagging and deformation due to humidity. There is.

This idea was made to improve the above-mentioned drawbacks of paulownia particle board.It not only prevents paulownia particle board from sagging or deforming due to humidity while using it, but also reduces damage during processing. Another object of the present invention is to provide a new paulownia wood that can be advantageous in terms of price.

The gist of these methods is to arrange relatively narrow rope boards and paulownia particle boards alternately in the width direction with the paulownia particle boards sandwiched between the rope boards, and then join them with adhesive to form a single piece. The paulownia laminated wood is characterized by the following: Next, this will be explained in detail based on the illustrated embodiment.

In the figure, the paulownia wood board according to this invention is designated by the reference numeral 1, and the paulownia wood board 1 is composed of a plurality of rope boards 2 and one or more paulownia particle boards 3.

The rope board 2 and the paulownia particle board 3 are both relatively narrow, and the side board 2 is made of paulownia leftover wood that is too narrow to be used as a board by itself, and can be used as is or with an appropriate width. The paulownia particle board 3 is formed by cutting the paulownia particle board product formed as described above into a predetermined width.

The rope boards 2 and paulownia particle boards 3 thus formed are arranged alternately in the width direction with the latter 3 sandwiched between the former 2, and are bonded together with an adhesive on both sides 2a and 3a of each. .

In this case, the number of combinations of rope boards 2 and paulownia particle boards 3 is as shown in Figure 1, as well as in Figure 4 a and l.
), etc., can be appropriately selected and determined depending on the purpose of use.

There is also no particular restriction on the usage ratio of the rope board 2 and paulownia particle board 3, but if the usage ratio of the rope board 2 is 50% or more, the paulownia wood 1 will be approved as paulownia wood for tax purposes. It has become.

After the rope board 2 and the paulownia particle board 3 are joined as described above, or the surface is finished using a wide sangu, the paulownia wood board 1 is completed.

The thus completed paulownia wood material 1 is then affixed with a veneer 4 or paper as shown in FIG. 3, and used as a component made of pure paulownia wood for furniture or building materials.

As mentioned above, in this invention, the paulownia particle board 3 is sandwiched between the mesh plates 2 and these are integrated with adhesive, so that the paulownia particle board 3 is supported by the mesh plate 2, and It is possible to reliably prevent sagging and deformation due to
Since all of the corner parts of the paulownia gluing material 1 are constructed of the mesh plate 2, damage to the corner parts during transportation and processing can be reduced.

Further, since the mesh board 2 and the paulownia particle board 3 have the same specific gravity, the paulownia wood material 1 formed by joining them together is as light as a paulownia wood panel, and its surface can be easily processed.

In addition, leftover paulownia wood, which cannot be used as a single material as a board, can be used for the mesh board 2, either as is or by cutting it, so it can be used effectively and reduce costs. There is an effect like this.

Claims (1)

[Scope of utility model registration request] Both of them are characterized in that relatively narrow rope boards and paulownia particle boards are arranged alternately in the width direction so that the paulownia particle boards are sandwiched between the rope boards, and these are joined with adhesive to form a single piece. Paulownia laminated wood.
