It relates to a structure in which a plurality of sheets are laminated with the fiber directions parallel to each other, bonded to a veneer laminated material, and then bent in a direction perpendicular to the fibers to form a triangular shape with a continuous cross section.
「従来の技術」

部分による空気断熱、防音性に優れているが、その反面
、曲げ、ねじれ、圧縮強度に劣る傾向となる。"Prior Art" Conventionally, various laminates have been developed and proposed in which a core is formed by appropriately processing wood boards, veneer veneers, paper, synthetic resins, etc., and the interior is hollow. In general, this type of laminate is lighter in weight than other laminates, and has excellent air insulation and soundproofing properties due to the hollow portion, but on the other hand, it tends to have poor bending, torsion, and compressive strength. becomes.
例えば、細長に分割した木板を、桟木として芯部に採用
し、この桟木を上下部材間の幅方向に分断して配列した
ものにおいては、桟木列間に上下部材を支持するものが
何ら介在しないので、ねじれ、曲げ強度が脆弱となり、
さらに中空部分については、圧縮強度に欠けることにな
る。For example, in the case where wooden boards divided into long strips are used as crosspieces in the core part, and these crosspieces are divided and arranged in the width direction between the upper and lower members, there is nothing intervening between the rows of crosspieces to support the upper and lower members. Therefore, the torsional and bending strength becomes weak,
Furthermore, the hollow portion lacks compressive strength.
また、ベニヤ単板を芯部とするに際しては、原木の個々

性状が相異し、且つベニヤ単板自体、繊維によって一応

は格子状等に加工して、上下部材間に接合している。し
かしながら、この接合時、その圧締力が過大になれば、
繊維が変形されて所望の中空部分を形成することは困難
となり、究極的には繊維が破壊されることになる。In addition, when using a veneer veneer as a core, the properties of the veneer veneer to be cut differ depending on the grade of the raw wood, cutting conditions, etc., and the veneer itself has a certain degree of directionality due to its fibers. However, since it is extremely fragile, it is processed into a tubular or lattice shape and joined between the upper and lower members. However, if the clamping force becomes excessive during this joining,
It becomes difficult for the fibers to be deformed to form the desired hollow portions, and ultimately the fibers will break.
また逆に、圧締力が過小であれば、接着不良の原因とな

曲げ、ねじれ等に劣シ、特に個々のベニヤ単板の相異に
より、一つの積層体内においても、圧縮強度にバラツキ
を生じる難点があった。On the other hand, if the clamping force is too low, it may cause problems in the manufacturing process, such as poor adhesion, or the strength of the core may be too low.
It has problems with bending, twisting, etc., and in particular, variations in compressive strength even within a single laminate due to differences in individual veneer veneers.
さらに、ハニカム状或いはロールコア状に加工した紙を

強度は大幅に低下するため、上下部材の材質、その重量
、使用用途が限定されることになる。Furthermore, when paper processed into a honeycomb shape or roll core shape is used as the core, the paper itself is made of defibrated wood fibers, so compared to the veneer veneer described above, the fiber directionality is lost, but , machining becomes easy. However, since the strength of the core portion is significantly reduced, the materials of the upper and lower members, their weight, and the intended use are limited.
さらにまた、芯部を非木質系の合成樹脂とした場合には
、製作加工が容易となる反面、ねじれ、曲げ強度に対し
てはもろく、且つ、切断、鋸断等に難点があるので、そ
の使用用途も必然的に限定されることになる。Furthermore, if the core is made of non-woody synthetic resin, it is easy to manufacture, but it is brittle in terms of torsion and bending strength, and it is difficult to cut, saw, etc. The intended use will also inevitably be limited.

Not only is it expected to be lighter, but it also improves bending, torsion, and compressive strength, and facilitates product processability such as cutting and sawing.Furthermore, the material of the upper and lower parts can be made optional, expanding the range of uses. The aim is to
「実施例」
以下に、本発明の実施例を添付図面に基づいて説明する
。"Example" Below, an example of the present invention will be described based on the accompanying drawings.
一般的に、複数枚のベニヤ単板1間に接着剤2を塗布し

しての真直性、剛性を有するものと認識されている。In general, a laminated veneer material 3 in which an adhesive 2 is applied between a plurality of veneer veneers 1 and the fibers are bonded in parallel is manufactured by applying an adhesive 2 between multiple veneer veneers 1 and bonding the fibers in parallel. For example, locally existing knots, irregular wood grains, etc. are dispersed evenly to improve moisture resistance and strength in the fiber direction, and it is recognized as having straightness and rigidity in one direction. There is.
従って、この認識に基づいて単板積層材3は、現状にお
いて、大なる圧縮荷重が掛る個所、例えば足場板、床板
等に多く使用されている。Therefore, based on this recognition, the laminated veneer material 3 is currently often used in places where large compressive loads are applied, such as scaffolding boards, floorboards, etc.
本発明においては、単板積層材3の特性である繊維方向
に有する強度を活用しながら、単板積層材3に対する従
来からの認識を打破して、まず繊維と直交する方向に折
り曲げ得る単板積層材3を製造することに着目したもの
である。In the present invention, while utilizing the strength in the fiber direction, which is a characteristic of the veneer laminate material 3, we have broken down the conventional understanding of the veneer laminate material 3, and first, we have created a veneer that can be bent in the direction perpendicular to the fibers. The focus is on manufacturing the laminated material 3.
しかして、複数枚のベニヤ単板1をその繊維方向と平行
に積層接着し、薄目の単板積層材3としながら、繊維と
直交する方向へ、その上下よシ任意間隔を置いて交互に
、例えば、平刃、丸刃等を軽く押し当てることによって
、筋状の切れ目4を形成する。次いで、この切れ目4が
内側に至るように単板積層材3を顆次折シ曲げ、断面が
連続する三角形状5となるように加工する。Thus, a plurality of veneer veneers 1 are laminated and bonded in parallel to the fiber direction to form a thin veneer laminate 3, and alternately in the direction perpendicular to the fibers at arbitrary intervals above and below, For example, the striped cuts 4 are formed by lightly pressing a flat blade, a round blade, etc. Next, the laminated veneer material 3 is condylarly bent so that the cuts 4 reach the inside, and processed so that the cross section becomes a continuous triangular shape 5.
このとき、三角形状5の上下に位置する各頂部6におい
ては、各層のベニヤ単板1のうち、内層となるものは、
その繊維の一部、若しくは全部が切れ目4によって、筋

板1の厚みが薄いので、各頂部6における外層のベニヤ
単板1の繊維は、接着剤2によってその伸長を拘束され
ず、応力は吸収されるので、三角形状5への加工が容易
となる。At this time, at each top 6 located above and below the triangular shape 5, among the veneer veneers 1 of each layer, the inner layer is
Some or all of the fibers are streak-like cracked or crushed by the cuts 4, so they contract easily, but the outer layer is more stressed when the fibers are stretched. However, since the adhesive 2 applied inside each veneer veneer 1 is still in a semi-gelled state and the thickness of the veneer veneer 1 is thin, the fibers of the outer layer of veneer veneer 1 at each top 6 are Since the adhesive 2 does not restrict its elongation and the stress is absorbed, processing into the triangular shape 5 becomes easy.
次いで、この三角形状5の単板積層材3に、表面部材7
と裏面部材8を介在させて、各頂部6とホッチキス等に
よって物理的に係止するか、若しくは図示の如く接着剤
2を塗布し、上下よシ接着して一体化した中空積層体9
を得るものである。Next, a surface member 7 is attached to this triangular-shaped veneer laminate 3.
A hollow laminate 9 is formed by physically fixing it to each top part 6 with a stapler or the like, or by applying an adhesive 2 as shown in the figure and bonding it from above and below with a back member 8 interposed therebetween.
This is what you get.

相殺されることになり、耐久強度を有するものである。This hollow laminate 9 not only has excellent torsion and bending strength in the direction parallel to each apex 6, but also has excellent torsion and bending strength in the direction perpendicular to each apex 6. is processed continuously from the laminated veneer material 3, so the compressive load acting on one hypotenuse of the triangular shape 5 is offset by the tensile strength generated as a reaction on the other continuous hypotenuse, which improves durability. It has strength.

Any material can be used as long as it can be processed.

A hollow laminate 9 in which the front member 7 and the back member 8 are specified as
According to this hollow laminate 9, in addition to the board strength of the formwork plywood 10, the triangular shape 5 interposed in the hollow core
The bending, twisting, and compressive strengths of the laminated veneer material 3 can be obtained. In addition, instead of this thick formwork plywood 10, the surface member 7
In addition, if a natural general-purpose board with a rating of 2.5 mm is used for the back member 8, it can be widely used for building materials such as wall materials, partitions, doors, etc., and furniture materials such as desks and low tables. It is also excellent in terms of sex.

となる。Furthermore, in the case shown in FIG. 6, the front member 7 and the back member 8 are made of gypsum board 11 among the above-mentioned inorganic materials, and the material is used for ceiling panels and wall materials for the purpose of flame retardancy. According to this hollow laminate 9, the gypsum board 11
Although it has no directionality and is fragile, it has strength due to the triangular veneer laminated material 3 interposed in the hollow core, making it easy to perform work such as linking, sawing, and construction at construction sites. becomes.
