Description

【発明の詳細な説明】 本発明は遮音性があり、かつ施工性に優れた建築用板に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction board that has sound insulation properties and excellent workability.

従来の建築用板としては、ベニヤ等の木質台板又は石コ
ウボードなどが用いられていたが、これらは多少の遮音
性又は吸音性を有するものの、外一部からの騒音及び階
層における騒音等を遮断することができなかったため、
鉛板や鉄板などの金属板を別個に用いるかあるいは合板
等に貼り合わせて設けて遮音性を持たせることが行なわ
れていた。Traditionally, wooden baseboards such as veneer or gypsum boards have been used as architectural boards, but although these have some sound insulation or sound absorption properties, they do not reduce noise from the outside and noise on floors. Because it was not possible to block
Metal plates such as lead plates and iron plates were used separately or bonded to plywood or the like to provide sound insulation.

しかしながら、このような遮音性を持たせた建築用板を
、床壁、天井などに使用する場合、突き合わせて施工す
るため、突き合わせ部に隙間が生じ易く音が洩れて遮音
効果が低下するという欠点を有し、結局この突き合わせ
部の隙間をコーキング材等でシールしなければならず、
施工に手間を要するという欠点を有していた。However, when building boards with such sound insulation properties are used for floors, walls, ceilings, etc., they are constructed by butting each other, so gaps tend to form at the butt parts, which causes sound to leak and reduce the sound insulation effect. In the end, the gap between this butt part must be sealed with caulking material, etc.
It had the disadvantage of requiring time and effort to construct.

本発明は上記従来の欠点に鑑みてなされたものであり、
それ自体遮音性を有すると共に、突き合わす施工におけ
る施工も容易で、突き合わせ部の隙間を隠蔽して遮音性
の低下を防止することのできる建築用板を提供するにあ
る。以下、図面に基づいて詳述する。The present invention has been made in view of the above-mentioned conventional drawbacks,
To provide a construction board which has sound insulating properties in itself, is easy to construct when butting together, and can prevent a decrease in sound insulating properties by concealing gaps in the butt parts. The details will be explained below based on the drawings.

石コウボードが用いられる。FIG. 1 is a perspective view showing a construction board according to the present invention, and FIG. 2 is a sectional view of the same, in which 1 is a plate-like base material, and 2 and 3 are soft sheets. As the plate-like base material 1, wood plywood such as veneer or gypsum board is used.

この板状基材１の両面には、熱可塑性樹脂中に鉄、鉛等

れている。On both sides of this plate-like base material 1, soft sheets 2 and 3 made of a thermoplastic resin mixed with a high specific gravity substance such as metal powder such as iron or lead or barium sulfate with a specific gravity of at least 4 or more are pasted. At the same time, the edges of the diagonal positions of the soft sheets 2 and 3 are respectively extended from the plate-shaped base material 1, and stacked pieces 4. A is provided.

いま、第３図に示すように、本考案の建築用板を突き合

れる。Now, as shown in Fig. 3, when the construction boards of the present invention are butted together and constructed, the stacking piece 4 of the building board A is attached to the stacking piece A of the building board λ. Thus, the gap between the abutting portions of the plate-shaped base materials 1 and 1' is hidden.

以上のように、本発明の建築用板は板状基材の両面に高
比重物質を混在してなる軟質シートを貼着すると共に、
該軟質シートの対角位置側端縁を板状基材より延出して
重ね代部を形成したので、それ自体が遮音性を有するの
は勿論、床、壁、天井等の建築用板として使用する場合
における突き合わせ部の隙間を完全に隠蔽することがで
きるため遮音性が低下することがないうえ、施工が簡略
化できる利点を有する。As described above, the architectural board of the present invention has a flexible sheet mixed with a high specific gravity substance attached to both sides of a plate-like base material, and
Since the diagonal side edges of the soft sheet are extended from the plate-shaped base material to form an overlapping section, it not only has sound insulation properties by itself, but also can be used as a construction board for floors, walls, ceilings, etc. Since it is possible to completely hide the gap between the abutted parts when the construction is carried out, there is no reduction in sound insulation properties, and it has the advantage that construction can be simplified.
