成したものに関する。Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a laminate having a hollow portion inside, and particularly relates to a laminate having a hollow portion inside, and is particularly applicable to a veneer lace, a veneer slicer, etc. This invention relates to a core made by laminating veneer veneers with their fiber directions crossing each other and bonding them to a bendable thin plywood board to form a continuous triangular cross section.
「従来の技術」
従来より、木板、ベニヤ単板、紙、合成樹脂等を適宜加
工して芯部を形成し、内部を中空構造とする積層体は種
々開発され、提案されている。一般的に、この種積層体
は、他のものに比し、その重量が軽量となり、且つ中空
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" 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
の等級、切削条件等によって、切削されるベニヤ単板の
性状が相異し、且つベニヤ単板自体、繊維によって一応
の方向性を有するが、極めて脆弱であるため、管状或い
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
る等、製作段階に支障を伴うばかりか、芯部の強度は、
曲げ、ねじれ等に劣り、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 will not only cause problems in the manufacturing stage such as poor adhesion, but also reduce the strength of the core.
It is poor in bending, twisting, etc., and has the disadvantage that the compressive strength varies even within a single laminate due to differences in the 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
芯部とした場合、紙自体は木材繊維を解繊して構成され
ているので、上記ベニヤ単板に比して、繊維の方向性は
無くなるが、加工は容易となる。しかしながら、芯部の
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.
さらに捷た、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 a non-woody synthetic resin, it will be easier to manufacture, but it will be brittle in terms of torsion and bending strength, and it will be 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 also facilitates product processing 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に接着剤2を塗布して

これに基づき、壁材、床材、天井材、家具材等、真直性
が要求されるものに、幅広く展開されている。Generally, plywood 3 is made by applying adhesive 2 to a plurality of veneer veneers 1 and laminating and bonding them with their fiber directions crossing each other. It is recognized that it has a certain straightness and rigidity by getting rid of the straightness and obtaining directionality in the vertical and horizontal directions. It has been widely used in various applications that require
従って、合板3は少なくとも真直度を保持できることを
目的として製造され、結果としてその最小厚みも、現状
2.511位に決定されている。Therefore, the plywood 3 is manufactured with the aim of maintaining at least its straightness, and as a result, its minimum thickness is currently determined to be about 2.511.
本発明においては、これら合板3に対する従来からの認
識を打破して、縦横に対する機械的強度は有するが、一
定の調性を無視して、まず折り曲げ可能な薄合板3を製
造することに着目したのである。In the present invention, we broke away from the conventional understanding of plywood 3 and focused on producing a thin plywood 3 that has mechanical strength in the vertical and horizontal directions but is bendable, ignoring a certain tonality. It is.
しかして、ベニヤ単板1の繊維方向を交差させて積層接
着し、薄合板3としながら、その上下より任意間隔を置
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薄合板3を順次折り曲げ、
断面が連続する三角形状5となるように加工する。Then, by laminating and bonding the veneer veneer 1 with the fiber directions crossed and forming a thin plywood 3, for example, by pressing lightly with a flat blade, a round blade, etc., alternately at arbitrary intervals from above and below. A striped cut 4 is formed. Next, the thin plywood 3 is sequentially bent so that the cuts 4 reach the inside,
It is 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lの繊維は、接着剤2によってその伸長を拘束され

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 veneer veneer l at each top 6 are Since its elongation is not restricted by the adhesive 2 and stress is absorbed, processing into the triangular shape 5 becomes easy.
次いで、この三角形状5の薄合板3に、表面部材7と裏

塗布し、上下より接着して一体化した中空積層体9を得
るものである。Next, this triangular-shaped thin plywood 3 is interposed with a front member 7 and a back member 8, and is physically fixed to each top part 6 with a stapler or the like, or an adhesive 2 is applied as shown in the figure. An integrated hollow laminate 9 is obtained by adhering from the top and bottom.

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 continuously processed from thin plywood 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, increasing the durability strength. It is something that you have.

It can be set arbitrarily.

A hollow laminate 9 in which the front member 7 and the back member 8 are specified as
is shown, and according to this hollow laminate 9, in addition to the plate strength of the formwork plywood 10, bending, torsion, and compressive strength can be obtained by the triangular thin plywood 3 interposed in the hollow core 1. . In addition, if instead of this thick formwork plywood 10 and a thin general-purpose board of about IF, MN is used for the front member 7 and back member 8, it can be used as a construction material for wall materials, partitions, doors, etc. ,desk,
It can also be used for floor holes in furniture materials such as low tables, and has excellent workability.

。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
has no directionality and is fragile, but the triangular thin plywood 3 interposed in the hollow core provides strength, making handling, sawing, construction, and other operations at construction sites easier.
