【発明の詳細な説明】
間伐材あるいは規格寸法径10.5cmの角柱を製造
した後のうら木等の小径木は、安価ではあるが利
用価値の少ないものであつた。[Detailed Description of the Invention] Although thinned wood or small-diameter wood such as back wood after producing prismatic pillars with a standard diameter of 10.5 cm is inexpensive, it has little utility value.
しかしながら最近の木材資源の不足と高価の現
状から小径木の活用が着目され、これを接着し大
径として再生利用することが研究されているが、
全体が均一且つ強固に接着され難く、接着不良や
強度の面で、未だ完全な集成板が製造されていな
い。 However, due to the recent shortage and high cost of wood resources, attention has been paid to the use of small-diameter trees, and research is being conducted on gluing these together and recycling them into large-diameter trees.
It is difficult to bond the entire board uniformly and firmly, and a perfect laminated board has not yet been manufactured due to poor adhesion and strength.
本発明は従来法の上記欠点に鑑み、小径木集成
材の生命である全素材の均一且つ強固な接着を目
的とし、多数並列した横断面が梯形の各梯形ラミ
ナー間の三角形の空隙に横断面が正三角形あるい

を安価且つ大量に製造できるようにしたものであ
る。 In view of the above-mentioned drawbacks of the conventional method, the present invention aims to uniformly and firmly bond all the materials that are the life of small-diameter laminated wood. By driving in a wedge-shaped lamina that is an equilateral or isosceles triangle and has two sides coated with adhesive, it is possible to produce laminated wood in large quantities at low cost, with all the materials bonding uniformly and firmly and having the same flat top surface. This is how it was done.

ビ形ラミナーを使用した場合の実施例について説
明する。 The wedge-shaped lamina used in the present invention has a first
As shown in the figure, the cross section is an equilateral triangle or an isosceles triangle, but the effect is exactly the same, so for convenience, we will explain an example in which a wedge-shaped lamina whose cross section is an equilateral triangle is used. do.
１は本発明に使用される間伐材あるいはうら木
等の小径材を素材とし、その横断面が梯形状の梯
形ラミナーである。 Reference numeral 1 is a trapezoidal lamina whose cross section is ladder-shaped and is made of small-diameter materials such as thinned wood or backwood used in the present invention.
２は横断面が正三角形のクサビ形ラミナーで、
第３図に示すように梯形ラミナー１の高さより１
mm以上大きく形成すると共にその二辺３および４
に接着剤を塗布した後、並列した多数の梯形ラミ
ナー１，１相互間の空隙５に挿入する。 2 is a wedge-shaped lamina with an equilateral triangular cross section.
1 from the height of the trapezoidal lamina 1 as shown in Figure 3.
mm or more and its two sides 3 and 4
After applying adhesive to the lamina, the lamina is inserted into the gap 5 between the many parallel trapezoidal laminas 1 and 1.
並列した多数の梯形ラミナー１の右端部６を縦
枠７で受止め、左端部８を側圧プレス９で押圧し
て幅決めを行なつた後、上方からホツトプレス盤
１０で押圧する。 The right end portions 6 of a large number of parallel trapezoidal laminars 1 are received by a vertical frame 7, the left end portions 8 are pressed by a side pressure press 9 to determine the width, and then pressed from above by a hot press plate 10.
この際各クサビ形ラミナー２の先端部１１は押
し潰され、両隣りの梯形ラミナー１，１との接着
を一層均一且つ強固にすると共に各梯形ラミナー
１とクサビ形ラミナー２との各上面を同一平面と
した集成板１２が作製される。 At this time, the tip part 11 of each wedge-shaped laminar 2 is crushed to make the adhesion with the trapezoidal laminars 1, 1 on both sides even more uniform and strong, and to make the upper surfaces of each trapezoidal laminar 1 and wedge-shaped laminar 2 the same. A flat board assembly 12 is produced.
この集成板１２の多数を第６図に示すように相
互に逆向きになるように積み重ねて接着し、ブロ
ツク状の集成材１３を作製する。 As shown in FIG. 6, a large number of the laminated boards 12 are stacked and glued in opposite directions to produce a block-shaped laminated timber 13.
この集成材１３は非常に強固なものとなつた
が、実際使用の場合はこれを垂直に切断して板状
または角材として使用するので、更に強固なもの
となつた。図中１４は集成板１２のフインガージ
ヨイント部である。 This laminated timber 13 has become extremely strong, but in actual use it has become even stronger because it is cut vertically and used as plates or square timbers. In the figure, reference numeral 14 indicates a finger joint portion of the composite plate 12.
本発明における側圧プレス９の横圧力は、両隣
りの梯形ラミナー１，１の下部隅角部が一点で接
しているので、全梯形ラミナー１を浮上させたり
右端部に進むに伴なつた横圧力が低下することな
く、全梯形ラミナー１および全クサビ形ラミナー
２を同一に押圧するので、接着を均一且つ強固に
することができる。 In the present invention, the lateral pressure of the lateral pressure press 9 is caused by the lateral pressure caused by floating all the trapezoidal laminars 1 and advancing toward the right end, since the lower corners of the trapezoidal laminars 1 and 1 on both sides are in contact at one point. Since the entire trapezoidal lamina 1 and the entire wedge-shaped lamina 2 are pressed equally without decreasing the adhesive strength, uniform and strong adhesion can be achieved.
またクサビ形ラミナー２は真つ直に降下するの
で、両隣りの梯形ラミナー１，１の斜辺に食い込
んだり節目に遮られることなく、接着材を均一且
つ強固に接着することができる。 Furthermore, since the wedge-shaped laminar 2 descends straight, the adhesive material can be bonded uniformly and firmly without digging into the oblique sides of the trapezoidal laminars 1, 1 on both sides or being obstructed by joints.
一方クサビ形ラミナー１は断面が正三角形であ
るため、同一に塗装機で全面均一に塗布でき、日
産数万本という大量塗布が正確にでき、非常に高
能率をなると共に接着剤を節約し経済的となつ
た。 On the other hand, since the wedge-shaped laminar 1 has an equilateral triangular cross section, it can be uniformly applied to the entire surface with the same coating machine, and it can accurately apply large quantities of tens of thousands of pieces per day, making it extremely efficient and saving adhesives, making it economical. It hit the mark.
以上は断面正三角形のクサビ形ラミナー２使用
の場合について説明したが、第１図に示した他の
断面二等辺三角形のクサビ形ラミナーを使用した
場合も全く同一に作用効果を営むことができる。 Although the case where the wedge-shaped laminar 2 with an equilateral triangular cross-section is used has been described above, the same operation and effect can be achieved even when the other wedge-shaped laminar with an isosceles triangular cross-section shown in FIG. 1 is used.
本発明は上記のように、従来至難とされた小径
材を接着した集成材の接着上の欠点を完全に除去
し、集成材の生命というべき均一且つ強固な接着
を寄能とした点に画期的な効果を有するものであ
る。 As described above, the present invention is characterized by completely eliminating the adhesion defects of laminated wood made by gluing small-diameter materials, which had been considered extremely difficult in the past, and by making it possible to achieve uniform and strong adhesion, which is the lifeblood of laminated wood. It has a long-term effect.
