図1は、本発明の実施の形態である木質パネルを利用した仮囲いを建設現場側から見た図である。FIG. 1 is a view of a temporary enclosure using a wood panel according to an embodiment of the present invention as viewed from the construction site side. 図2は、本発明の実施の形態である木質パネルの性能を定性的に示した図である。FIG. 2 is a view qualitatively showing the performance of the wood panel according to the embodiment of the present invention.

以下に、本発明にかかる木質パネルおよび当該木質パネルの製造方法の実施の形態を図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。   Hereinafter, embodiments of a wood panel and a method for producing the wood panel according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

図1は、本発明の実施の形態である木質パネルを利用した仮囲いを建設現場側から見た図である。本発明の実施の形態である木質パネル1は、建設期間中、建設現場と外部とを遮断するために現場周囲に設置する仮囲いに利用されるものであって、図1に示すように、現場側に架設した単管2をパネル支持材とし、隙間なく貼設される。貼設にあたり、木質パネル間の隙間をなくし、組立構造を安定化するために木質パネルの側面に実矧ぎ加工がされてもよい。   FIG. 1 is a view of a temporary enclosure using a wood panel according to an embodiment of the present invention as viewed from the construction site side. The wood panel 1 according to the embodiment of the present invention is used for a temporary enclosure to be installed around the site in order to shut off the construction site and the outside during the construction period, as shown in FIG. The single pipe 2 erected on the site side is used as a panel support material, and is pasted without any gaps. In pasting, in order to eliminate the gap between the wooden panels and stabilize the assembly structure, the side surface of the wooden panel may be subjected to actual rowing.

建設現場の周囲に設置する仮囲いに利用される木質パネル1は、高さが2000〜4000mm(3000mmのものが多い)と大型となるため、繊維方向が平行となるように単板が積層された単板積層材(LVL(Laminated Veneer Lumber))あるいは繊維方向が交差するように単板が積層された合板に合成樹脂を含浸させたものが用いられる。含浸させる合成樹脂は、たとえば、取扱性やコストの面からフェノール樹脂が好ましいが、メラミン樹脂、エポキシ樹脂、不飽和ポリエステル樹脂など含浸性と硬化性の良好な樹脂を用いることができる。また、フェノール樹脂は、水溶性であっても油溶性であってもよい。   The wood panel 1 used for the temporary enclosure installed around the construction site has a large size of 2000 to 4000 mm (many of 3000 mm), so a single plate is laminated so that the fiber directions are parallel. A single plate laminated material (LVL (Laminated Veneer Lumber)) or a plywood laminated with a single plate so that the fiber directions cross each other is used. As the synthetic resin to be impregnated, for example, a phenol resin is preferable from the viewpoint of handleability and cost, but a resin having a good impregnation property and curability such as a melamine resin, an epoxy resin, and an unsaturated polyester resin can be used. The phenol resin may be water-soluble or oil-soluble.

単板積層材および合板は、乾燥単板を用いることにより含水率が均一化され、同時に節などの欠点部分も分散されるため、寸法の安定性と精度に優れており、さらに、合成樹脂を含浸させることにより、耐久性と強度を向上させている。   Veneer laminates and plywood have a uniform moisture content by using dry veneer, and at the same time, disperse defects such as joints, so they have excellent dimensional stability and accuracy. Impregnation and strength are improved by impregnation.

ここで用いられる単板の厚みは、3.2mm程度であり、単板積層材あるいは合板における単板の積層枚数は、木質パネル1の曲げに対する強度・剛性、重量(20kg以下が好ましい)などから7〜10枚となり、木質パネル1の厚みは、20〜30mmとなる。   The thickness of the single plate used here is about 3.2 mm, and the number of laminated single plates in the single plate laminated material or plywood is based on the strength and rigidity against bending of the wood panel 1, weight (20 kg or less is preferable), etc. 7 to 10 sheets, and the thickness of the wood panel 1 is 20 to 30 mm.

さらに、合成樹脂を含浸させた単板積層材あるいは合板を加熱プレスすることにより、木質パネル1の表層に樹脂強化部(図示せず)を設けることが好ましい。   Furthermore, it is preferable to provide a resin reinforced portion (not shown) on the surface layer of the wood panel 1 by heat-pressing a single plate laminated material or a plywood impregnated with a synthetic resin.

図2は、本発明の実施の形態である木質パネルの性能を定性的に示した図である。図2に示すように、スギ合板にフェノール樹脂を含浸させた木質パネル1は、少ないコストで耐久性および強度・剛性が向上する一方、フェノール樹脂を含浸させたスギ合板を加熱プレス(圧縮率:10〜20%)することにより、表層に樹脂強化部を設けた木質パネル1は、単板積層材あるいは合板にフェノール樹脂を含浸させた木質パネル1よりもコストがかかるものの、耐久性および強度・剛性がさらに向上する。   FIG. 2 is a view qualitatively showing the performance of the wood panel according to the embodiment of the present invention. As shown in FIG. 2, the wood panel 1 in which a cedar plywood is impregnated with a phenol resin is improved in durability, strength and rigidity at a low cost, while the cedar plywood impregnated with a phenol resin is heated by pressing (compression ratio: 10-20%), the wood panel 1 provided with a resin reinforced portion on the surface layer is more costly than the wood panel 1 in which a single board laminated material or a plywood is impregnated with a phenol resin, but durability and strength / The rigidity is further improved.

上述した実施の形態である木質パネルは、単板積層材あるいは合板(無処理)よりも耐久性および強度・剛性が向上するので、建設現場の周囲に設置する仮囲いに利用できる。   The wood panel according to the embodiment described above can be used for a temporary enclosure to be installed around a construction site because durability, strength, and rigidity are improved as compared to a single-plate laminated material or plywood (no treatment).

そして、本実施の形態である木質パネルを仮囲いに利用すれば、地域材を有効利用でき、CO2の削減に資することができる。更に、単板をスギの単板とすれば、花粉症の対策にもなる。   And if the wood panel which is this Embodiment is used for temporary enclosure, a local material can be used effectively and it can contribute to reduction of CO2. Furthermore, if the veneer is a cedar veneer, it will be a countermeasure against hay fever.

また、本実施の形態である木質パネル1を仮囲いに利用すれば、都市建設現場のイメージアップにも資することになる。   Moreover, if the wood panel 1 which is this Embodiment is used for temporary enclosure, it will contribute to the image improvement of a city construction site.
