Description

[Detailed description of the invention] (Industrial application field) This invention relates to panels made from thinned wood that are intended to prevent warping and twisting by arranging the wood obtained from thinned wood in predetermined conditions. It is something.

(Problems to be solved by the prior art and invention) Conventionally, panels are constructed by forming a frame material with vertical and horizontal bars, and surface materials are fixed in parallel to one side of the frame material. When wood obtained from thinned wood is used as a component, the cracks, warping, and twisting that occur in each component affect the entire panel, and the panel itself often warps or twists, making it impossible to obtain a usable panel. .

(Means for solving the problem and their effects) However, when using a material obtained from thinned wood that is prone to cracking, warping, and twisting, this invention is designed to offset the stress caused by the warping and twisting. By arranging the materials, there is no warping or twisting of the panel itself, solving the above problems, expanding the usable range of thinned wood, and successfully producing panels at low cost.

(Embodiment) That is, to explain this invention in terms of an embodiment, as shown in FIGS.
When forming the panel 5 by fixing them in parallel, the frame material 3 (Fig. 4) is made of horizontal bars 2 made of core material obtained from thinned wood at predetermined intervals (for example, 450 mm pitch).
are arranged in parallel with each other, and vertical bars 1, 1 are fixed to both sides thereof. The vertical beam 1 is made of narrow boards 6, 6 obtained from thinned wood.
(This is a material other than the core holding material.) As shown in FIG. 5, the wood front sides are brought into contact with each other and joined to form a predetermined size.

Next, the surface materials 4, 4 are similar to the material 6,
As shown in Figures 6 and 7, when narrow boards obtained from thinned wood are used and fixed in parallel to one side of the frame material 3, a wooden front 4a and a wooden back 4b are placed on the upper side. They are arranged alternately and with a slight gap 7 between each surface material 4, 4, and the contact surfaces with the frame material 3 are bonded. When the panel 5 is made of material obtained from thinned wood as described above, it has the following characteristics.

That is, since the vertical beam 1 is joined with the wooden front sides of the narrow boards 6, 6 in contact with each other, warping and twisting of the narrow board 6 can be prevented, and irregularities and chips on the wooden front of the narrow board 6 can be prevented. can be contained inside the vertical bar 1, and the appearance of the vertical bar can be made beautiful. Since the horizontal bar 2 is used as a core support material, the horizontal bar 2 and the vertical bar 1 work together to make the frame material 3 itself consistent.

In addition, since the facing materials 4, 4 are narrow boards with wooden fronts and wooden backs arranged alternately, the stress on the frame material 3 due to warping, twisting, etc. of each facing material 4 can be canceled out, and the panel 5 It is possible to prevent distortions such as warpage and twisting of the product itself. Furthermore, by interposing the gap 7 between the surface materials 4, 4 as in the embodiment, it is possible to secure room for expansion and contraction of the surface materials 6, and as a result, it is possible to cause the surface materials 4, 4 to move wildly, thereby preventing distortion in the panel 5. can not be internalized.

(Effects of the invention) As described above, according to this invention, the frame material itself is made to be consistent, and a surface material made of a narrow board obtained from thinned wood is placed on one side of the frame material, and the front and back sides are alternately changed. Since the panel is constructed by being fixed in parallel, it has the effect of being able to provide a panel that is free from warping or twisting, and also has various effects such as expanding the range of use of thinned wood and being able to provide the panel at a low price.

Further, by providing a gap between the parallel surface materials, there is an effect that distortion due to expansion and contraction of the surface materials is not inherent in the panel.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a panel made of a frame material assembled with vertical and horizontal bars with a surface material fixed in parallel to one side, the frame material is made of core material obtained from thinned wood. It consists of a horizontal crosspiece and a vertical crosspiece in which the wooden faces of narrow boards obtained from thinned wood are joined to each other, and the surface material is made by fixing narrow boards obtained from thinned wood by alternating the front and back sides. A panel made from thinned wood that is characterized by the fact that it is (2) A panel in which the surface material is made of thinned wood as described in claim (1) of the utility model registration, which are arranged in parallel with a gap in between.
