Description

【0001】
【考案の属する技術分野】
本考案は、結露防止の建材として室内壁面に用いる不燃性断熱ボードに関する。
【0002】
【従来の技術】
従来より外壁内壁間には断熱材として断熱ボードが用いられており、また塗料としての結露防止塗材が存在している。
【0003】
【考案が解決しようとする課題】
従来より、壁面結露が生じる家屋室内の施工工事において、対処として外気温との温度差を軽減するためにまず断熱材を装てんすることが一般におこなわれているが、例えばコンクリート塗りの壁面では断熱材を壁面内部に装てんすることが出来ず、表面に対して結露防止塗料等の調湿性塗材を塗布する程度で、その対処が充分に出来ていなかった。
【0004】
【課題を解決するための手段】
本考案は、外気温との温度差を軽減するための不燃性断熱ボードに、下地塗りと表面に結露防止塗料等の調湿性塗材を塗布施工済みとすることで、室内コンクリート壁面に対しても直接貼り合わせ施工をおこなうことができ、断熱性の向上と現場施工工事の効率も向上するよう手段を講じたものである。
【0005】
【考案の実施の形態】
考案の実施の形態を以下に説明する。
図1に例を示すとおり、本考案にかかる結露防止断熱ボードは、不燃性断熱材を基板とし、表面にガラスクロスを張り付けてセメント系フィラーを塗布し、更に結露防止塗材を塗り重ねた構造となっている。
【0006】
【実施例】
基板となる不燃性断熱材は、一般的に炭酸カルシウム発泡板を用いることで、充分な断熱性能を得られると共に軽量で持ち運びが用意であるため適している。
【0007】
従来、断熱材としてはグラスウール等が内外壁間に装てんされているが、経年劣化でその断熱性能が低下したり、水分を吸湿したままになる問題があった。
【0008】
しかしながら、本考案製品に用いる断熱材としての炭酸カルシウム発泡板は、軽量でありながらも板状で保形性が高く、現場施工も比較的容易であって切断加工性も問題がない上、施工後も長期に亘り安定した性能を維持できる。
【0009】
まず、定格サイズ、一般的に1800mm×900mm、厚みは発泡板の製品規格により選択可能で標準として10mm厚の炭酸カルシウム発泡板の片側全面にガラスクロスを貼付するが、この場合糊等の固着剤を用いるか、或いはガラスクロスに接着剤が塗布された製品が存在するのでこれを用いて発泡板に貼り付けをおこなう。ガラスクロスの貼付は、基板たる発泡板の反りを押さえるために使用する。また、ガラスクロスによって本考案製品の表面には凸凹が生じるので、網目状の模様がそのまま製品として使用できることになる。
【0010】
ガラスクロスの貼付後、セメント系フィラーを乾燥後厚0.1mm〜0.2mm程度になるよう塗布することにより、ガラスクロスを基板に固着させる。セメント系フィラーが完全に乾燥するまで1日乃至2日間の養生期間を置く。この処理によってガラスクロスが強固に基板と一体化するので、多少の圧擦によっても剥がれることがなく製品の反りを防止することができる。
【0011】
セメント系フィラーの乾燥後、中毛ウーローラー等を用いて結露防止塗材を塗厚1mm〜2mm程度に全面塗布する。この後乾燥のための養生期間を1日程度おくと、塗材が痩せて下地のガラスクロスによる凸凹が浮き出ることによって、網目状の模様が表面に形成される。
【0012】
なお、結露防止塗材の色によって本考案製品の色彩も変えることが可能であるが、基本的に施工現場にて更に結露防止塗材を上塗りして仕上げるため、下地として白色系或いは淡色系の塗材が主に使用される。
【0013】
【考案の効果】
この考案は前記のように構成されており、以下に記載のような効果を有する。
【0014】
近年では、住宅室内の機密性が向上したために冬場の結露問題が増加しており、施工対象がコンクリート壁面などの場合には、外気温との温度差を根本的に解消することが出来ずに単に結露防止塗材を塗布施工する程度で、塗材の調湿能力を超えてしまい再び結露問題が生じることもあった。
【0015】
その対策として、外気温との温度差を軽減するために断熱材を用いて施工する方法がとられてきたが、各現場において断熱材の壁面貼付施工に始まり、結露防止塗材の塗布、乾燥、更に仕上げ塗布など、多くの工程を施工現場において要しており作業性も悪かった。
【0016】
本考案製品は、断熱材に結露防止塗材の一度塗りを済ませた下地ボードとして販売されるので、現場においては従来通りに断熱材を壁面に貼る要領にて使用することができ、継ぎ合わせ部の目地処理をした後に好みの色の結露防止塗材を上塗りして仕上げることができる。
【0017】
また、結果的に結露防止塗材を二度塗りすることとなるので、充分な塗厚を形成でき、調湿性が向上し防露効果がより期待できる。
【0018】
また、例えば押入内壁面などの結露防止のために本考案製品を使用する場合には、化粧仕上げを要しないので結露防止塗材の上塗りをすることなく本考案製品をそのまま壁面に貼付施工することによって、作業性が向上し且つ充分な防露効果を得ることができる。
【0019】
更に本考案製品は、その表面が下地に貼付されたガラスクロスによる網目模様となっており、現場における結露防止塗材を仕上げ塗布する作業において、上塗りの塗材が載りやすい効果を有している。
【0020】
また、結露状態によって断熱材の厚みを大きく取ることが望ましい場合には、本考案製品を壁面に二重貼りすれば断熱性能が向上し、結露問題を解消することができる。
【0021】
なお、本考案製品の上から板材やクロスを貼り付けたり、通常のペイントを塗布すると結露防止塗材による調湿性能が失われるので、必ず内壁表面には結露防止塗材を塗布する。
【0022】
上記のように断熱材と結露防止塗材を一体化したことによって、防露効果が向上すると共に現場作業性も向上する効果を有する。

[Technical field to which the invention belongs]
The present invention relates to a non-combustible heat insulating board used as a building material for preventing dew condensation on an indoor wall surface.
[0002]
[Prior art]
Conventionally, a heat insulating board has been used as a heat insulating material between the outer and inner walls, and a dew-prevention coating material as a paint has been present.
[0003]
[Problems to be solved by the invention]
Conventionally, in the construction work in a house room where dew condensation on the wall surface occurs, it is common practice to first install heat insulating material in order to reduce the temperature difference from the outside air temperature. Could not be mounted on the inside of the wall surface, and only a moisture-controlling coating material such as a dew-condensation prevention paint was applied to the surface, and the measures could not be taken sufficiently.
[0004]
[Means for Solving the Problems]
The present invention applies a humidity control coating material such as anti-condensation paint to the base coat and the surface of the non-combustible heat insulating board to reduce the temperature difference from the outside air temperature, so that it can be applied to the interior concrete wall. It is possible to perform direct lamination work, and measures are taken to improve the heat insulation and the efficiency of construction work on site.
[0005]
[Embodiment of the invention]
An embodiment of the invention will be described below.
As shown in FIG. 1, the dew condensation prevention heat insulating board according to the present invention has a structure in which a non-combustible heat insulating material is used as a substrate, a glass cloth is adhered to the surface, a cement filler is applied, and a dew condensation prevention coating material is further applied. It has become.
[0006]
【Example】
The non-combustible heat insulating material used as the substrate is generally suitable by using a calcium carbonate foam plate because it can provide sufficient heat insulating performance and is lightweight and portable.
[0007]
Conventionally, glass wool or the like is mounted between the inner and outer walls as a heat insulating material. However, there has been a problem that the heat insulating performance is deteriorated due to aging, or moisture is kept absorbed.
[0008]
However, the calcium carbonate foam board as a heat insulating material used in the product of the present invention is lightweight, plate-like, has high shape retention, is relatively easy to perform on site, and has no problem in cutting workability. Thereafter, stable performance can be maintained for a long period of time.
[0009]
First, the rated size, generally 1800 mm x 900 mm, and the thickness can be selected according to the product standard of the foam board. As a standard, a glass cloth is adhered to the entire surface of one side of a 10 mm thick calcium carbonate foam board. Or a product in which an adhesive is applied to a glass cloth is used, and the product is attached to a foam plate using the product. The attachment of the glass cloth is used to suppress the warpage of the foam plate as the substrate. In addition, since the surface of the product of the present invention is uneven due to the glass cloth, the mesh pattern can be used as the product as it is.
[0010]
After attaching the glass cloth, the glass cloth is fixed to the substrate by applying a cement-based filler to a thickness of about 0.1 mm to 0.2 mm after drying. A curing period of one to two days is allowed for the cement-based filler to dry completely. Since the glass cloth is firmly integrated with the substrate by this processing, the product can be prevented from being warped without being peeled off even by slight rubbing.
[0011]
After the cement-based filler is dried, a dew-prevention coating material is applied to the entire surface to a thickness of about 1 mm to 2 mm using a medium wool roller or the like. After that, if the curing period for drying is set to about one day, the coating material becomes thin and irregularities due to the underlying glass cloth emerge, thereby forming a mesh-like pattern on the surface.
[0012]
It is possible to change the color of the product of the present invention by the color of the anti-condensation coating material. Coating materials are mainly used.
[0013]
[Effect of the invention]
This invention is configured as described above and has the following effects.
[0014]
In recent years, the dew condensation problem in winter has increased due to the improvement of the confidentiality in the housing room, and when the construction target is a concrete wall, etc., it is not possible to fundamentally eliminate the temperature difference from the outside temperature. Simply applying the dew-prevention coating material may exceed the humidity control capability of the coating material, and may cause a dew condensation problem again.
[0015]
As a countermeasure, the method of using insulation materials to reduce the temperature difference from the outside air temperature has been adopted.However, at each site, the application of the insulation material to the wall surface, the application of dew condensation prevention coating material, and the drying In addition, many steps such as finish coating were required at the construction site, and workability was poor.
[0016]
The product of the present invention is sold as a base board in which the heat-insulating material has been coated once with anti-condensation coating material. After finishing the joint processing, a desired anti-condensation coating material of a desired color can be overcoated and finished.
[0017]
Further, as a result, the anti-condensation coating material is applied twice, so that a sufficient coating thickness can be formed, the humidity control property is improved, and the anti-dew effect can be more expected.
[0018]
Also, when using the product of the present invention to prevent dew condensation on the inner wall of the indentation, for example, it is not necessary to apply a decorative finish, so the product of the present invention should be applied to the wall surface without coating the anti-condensation coating material. Thereby, workability is improved and a sufficient dew-proof effect can be obtained.
[0019]
Further, the product of the present invention has a mesh pattern formed by a glass cloth attached to the base, and has an effect that the top coating material is easily put on in the work of finishing application of the anti-condensation coating material on site. .
[0020]
Further, when it is desirable to increase the thickness of the heat insulating material depending on the dew condensation state, the heat insulation performance is improved by double applying the product of the present invention to the wall surface, and the dew condensation problem can be solved.
[0021]
If a plate or cloth is pasted on the product of the present invention, or if ordinary paint is applied, the moisture control performance of the anti-condensation coating material is lost, so the anti-condensation coating material must be applied to the inner wall surface.
[0022]
By integrating the heat insulating material and the dew condensation preventing coating material as described above, there is an effect that the dew prevention effect is improved and the on-site workability is also improved.
