JPS5850966Y2 - Veneer laminate using softwood veneer - Google Patents

Description

[Detailed description of the invention] This invention relates to a veneer laminate made of veneers of coniferous wood such as cypress, Japanese pine, and cedar.Furthermore, it effectively utilizes the coniferous wood whose conventional use was limited, and uses it as a sill and lintel. This invention relates to a laminate of needle-fallen wood veneer that can be applied to edge decks, etc.

That is, as shown in Figure 1, softwood veneers are spliced lengthwise and abutted in the length direction, and the front and back sides are continuously joined with hot melt thread, and the abutting parts are joined (the abutting parts are joined by point joints). )
These are laminated, and in this case, by arranging the front and back of the wood on the same surface alternately, warping, twisting, distortion, cracking, etc. of the laminate made of these veneers can be prevented as much as possible. , and can also be made into a laminate with uniform thickness at each part.

Next, the first embodiment of the present invention that can achieve the above purpose will be described.
Figures 1 to 2 will be explained in detail.

1 indicates a veneer made of coniferous wood such as cypress, Japanese pine, and cedar with an end diameter of about 12 crn, and obtained by rotary lace, for example, with a length l, a width W of about 50 crn, and a thickness of about 2 mm. is used.

Figure 1 is an explanatory diagram of the means of joining veneers 1, and each veneer 1 has a wooden surface 1.
This is a perspective view of the case where a and the wooden back 1b are alternately abutted in the length direction, and the front and back sides are continuously joined with a plurality of hot melt threads 2, and a plurality of points of the abutting portion are point-welded 3, This constitutes a single plate a.

In addition, Fig. 2 shows a laminate in which a large number of the above-mentioned single plates a are laminated and bonded together, and the vertical relationship of the abutting parts of each single plate is such that the abutting part of the lower plate is the same as that of the upper plate. This is an explanatory diagram of the case where the veneers are laminated so as not to match the abutting portions, and 1a shows the wood surface and 1b shows the wood back, but the numbers for the wood surface and the wood back of the veneer 1 are omitted.

Since the present invention has the above-mentioned caveats, we use coniferous wood such as cypress, Japanese pine, and cedar, which range from about 12 cm in the last days to about 8 cm in the last days, which were previously limited in use, to create thresholds, lintels, etc. Edge deck etc. are obtained.

Furthermore, warping, twisting, distortion, cracking, etc. occur when stacking the veneers 1 by abutting them in the length direction, continuously joining the front and back sides with hot melt thread 2, and joining 3 the abutting portions. It is possible to prevent this as much as possible, and when performing vertical joints (length direction) and horizontal joints (width direction) as described above,
By alternately abutting the front side of the wood and the back side of the wood, there is an effect that the range of selection based on the quality of the cut surface of the veneer at the time of abutment can be expanded.

Therefore, the purpose can be well achieved by performing post-processing such as pasting a veneer on the surface or side surface portion depending on the purpose.

Claims (1)

[Scope of utility model registration request] Coniferous wood veneers such as cypress, Japanese pine, and cedar are lined up in series in the length direction so that the front and back sides of the wood are alternated on the same side.
A veneer laminate is made by laminating these veneers.
