の補強部材３との接合用端面４を精度よく仕上げなげれ
ばならずコスト高となり、また、その接合部分が美観を
低下させるという問題があった。As shown in Fig. 1, conventional irregularly shaped laminated timber is made by laminating and bending a large number of plates 1 into a groove shape, filling the inside of the groove with a core material 2, and reinforcing the open end. Since the members 3 are finished by joining them together, the number of parts and the number of times of joining are large, and the attached board 1 after lamination and bending is
The end face 4 for joining with the reinforcing member 3 must be finished with high precision, resulting in high costs, and there is also the problem that the joined part deteriorates in appearance.

y # meeting Kirileto y #kaiKirireto yo cost text R Y θ) srl , force 4 request a) When obtaining a stained irregularly shaped laminated lumber 6,
Logs generally have local defects, so
There has been a problem in that it is difficult to obtain defect-free sliced veneers over a long length, resulting in significantly poor yields and high costs.
したがって、この発明の目的は、外観のすぐれた製造コ
ストの安い異形集成材を提供することである。Therefore, an object of the present invention is to provide a deformed laminated lumber that has an excellent appearance and is inexpensive to manufacture.
この発明の実施例を第３図ないし第７図に基づいて説明
する。An embodiment of the invention will be described based on FIGS. 3 to 7.
すなわち、この異形集成材は、第３図Ａに示すように、
つき板７０表面に接着剤８を塗布して同図Ｂのように積
層し、同図Ｃに示すように両端部９のそれぞれの上面に
積層されたつき板７の厚み分だけ切欠いた四角柱からな
る雄金型１０をその切欠部１１部分で当接して、同図Ｃ
〜Ｅで示すようにその積層つき板７で雄金型１０を包み
込むように折曲げ、両端部９を相互に接合して筒状に形
成し、外周からカロ熱、加圧して成形したものである。That is, as shown in Fig. 3A, this irregularly shaped laminated timber has the following characteristics:
The adhesive 8 is applied to the surface of the attached plate 70, and the layers are stacked as shown in FIG. The male mold 10 consisting of
As shown in ~E, the laminated plate 7 is bent so as to wrap around the male mold 10, and both ends 9 are joined together to form a cylindrical shape, which is then molded by heat and pressure from the outer periphery. be.
なお両端部９の接合面１２は同図りの段階で接着剤８を
塗布している。Note that the bonding surfaces 12 of both end portions 9 are coated with adhesive 8 at the same stage.
また、成形を終ったこの異形集成材は雄金型１０を抜去
して第４図のような製品とするものである。Further, the male mold 10 is removed from this irregularly shaped laminated material which has been molded to produce a product as shown in FIG. 4.
このように構成した異形集成材は、外周面につき板７の
積層端面１３が全く現われずむく材と少しも見劣りしな
い外観を呈するため、柱や框としてそのまま利用できる
うえ、従来の異形集成材のように芯材や補強部材と接合
する必要がないため材料コストを低減でき、さらにつき
板７の積層端面１３を精度よく揃えて仕上げる必要がな
くなり、その工程を省略できるという効果がある。The irregularly shaped laminated timber constructed in this way does not show any of the laminated end faces 13 of the plates 7 on the outer circumferential surface and has an appearance that is not inferior to that of solid wood, so it can be used as is as a pillar or frame, and it is superior to conventional irregularly shaped laminated timber. As there is no need to join the core material or the reinforcing member, the material cost can be reduced, and there is also no need to precisely align and finish the laminated end faces 13 of the attached plates 7, and this process can be omitted.
さらにまた、この異形集成材は両端部９の接合面積（接
着剤８の塗布面積）が広いので接着強度を高めることが
できる。Furthermore, since this irregularly shaped laminated material has a large joint area (area where adhesive 8 is applied) at both ends 9, the adhesive strength can be increased.
なお、この実施例における雄金型１００代りに芯材を用
いてこれを抜去せずにそのまま補強部材としての作用を
もたせるようにしてもよく、また、これら型の代りにロ
ールフォーミングにより筒状に成形するようにしてもよ
い。Incidentally, instead of the male mold 100 in this embodiment, a core material may be used so that it can function as a reinforcing member without being removed, and instead of these molds, it can be made into a cylindrical shape by roll forming. It may also be molded.
また、第５図はこの発明の他の実施例の断面を示すもの
であり、積層されたつき板１４の両端を積層端面１５が
内側となるように相互に筒状に接合して、その接合部１
６の先端１７を筒体内の対向面にまで延長して接合した
もので、接合部１６が補強用リブとして作用するように
している。Further, FIG. 5 shows a cross section of another embodiment of the present invention, in which both ends of the stacked plates 14 are joined to each other in a cylindrical shape with the stacked end faces 15 facing inside. Part 1
The tip 17 of 6 is extended to the opposing surface inside the cylinder and joined, so that the joint 16 acts as a reinforcing rib.
さらに、第６図および第７図は他の実施例であり、それ
ぞれつき板１８，１９を積層してその積層端面２０，２
１を内側にして断面３角、６角の筒体を形成するように
接合しており、それぞれの用途に応じて各種の形状に成
形できることを示している。Further, FIGS. 6 and 7 show other embodiments in which attached plates 18 and 19 are laminated, and the laminated end surfaces 20 and 2 are laminated, respectively.
They are joined to form cylinders with triangular and hexagonal cross sections with 1 facing inside, indicating that they can be molded into various shapes depending on their respective uses.
以上のように、この発明の異形集成材は、積層したつき
板の両端部を巻き込んで双方の外表面同士を接合して筒
状に形成したため、外観がすぐれ、製造コストが安価で
あり、さらに接合部分の強度を高めることができるとい
う効果を有する。As described above, the irregularly shaped laminated timber of the present invention is formed into a cylindrical shape by rolling up both ends of laminated plates and joining the outer surfaces of both sides, so it has an excellent appearance, is low in manufacturing cost, and has an excellent appearance. This has the effect of increasing the strength of the joint.
