本考案はセメント瓦屋根等に使用して好適な野
地材に関するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a field material suitable for use in cement tile roofs, etc.
（従来の技術）
瓦屋根等の野地板に断熱性を与える為に、例え

のである。(Prior art) In order to provide heat insulation to the roofing boards of tiled roofs, etc., for example, the roofing boards described in Publication of Utility Model Publication No. 12041/1983,
It is known that a plurality of foamed thermoplastic resin plates are installed on the back side of a particle board, and the foamed thermoplastic resin plate is fixed to the main building material with the bottom surface, roofing is laid on the top surface, and roof tiles are placed on top. The idea is to provide insulation between the indoor and outdoor sides by roofing.
（考案が解決しようとする問題点）
然し乍ら、上記従来の野地材では、断熱材とし
てポリスチレン等殆ど吸水性、吸湿性のない樹脂

が劣り、強度や耐久性にも悪影響をもたらすので
ある。(Problem to be solved by the invention) However, in the above-mentioned conventional field materials, a resin layer such as polystyrene that has almost no water absorption or hygroscopicity is used as a heat insulating material. The water vapor that is generated and rises is not absorbed and condenses on the wood surfaces of the main building materials, bundles, beams, etc., or is absorbed and damages the wood.In addition, if rainwater leaks from the roofing. Since the rainwater absorbed by the roof board cannot be easily evaporated, the roof board is not dried, and the moisture-containing roof board has poor insulation properties, which has a negative impact on its strength and durability.
（考案の目的）
本考案の第一の目的は、上記従来の欠点を解消
し、屋根内部の過剰な水蒸気を吸収して空気を乾
燥に導き、水分が母屋材等の木材に結露したり吸
収されて木材を傷めることがなく、また、冬期等
の屋内側の空気が過乾状態になつた場合に適度の
湿気を供給して湿度を調節し過乾による木材の歪
や火災に対する危険性を減少させることにある。(Purpose of the invention) The first purpose of the invention is to eliminate the above-mentioned conventional drawbacks, to absorb excess water vapor inside the roof and to dry the air, so that moisture does not condense on the wood such as the main building material or is absorbed. It does not damage the wood, and when the indoor air becomes overly dry during the winter, it supplies an appropriate amount of moisture to regulate the humidity, preventing warping of the wood and the risk of fire due to overdrying. The goal is to reduce it.
本考案の第二の目的は、従来、セメント瓦に含
まれる水分が冬季に凍結し、それが屋内の熱によ
つて融解され、この凍結・融解による水の体積変

ことのできる野地材を提供せんとするものであ
る。 The second purpose of this invention is that the moisture contained in cement tiles freezes in the winter and is thawed by indoor heat, and the volume change of water due to freezing and thawing is repeated. In order to prevent roof tiles from cracking, keep the roof boards dry at all times to maintain their insulation properties, which blocks heat from indoors and prevents the moisture contained in the tiles from repeatedly freezing and thawing, thereby preventing tiles from cracking. The aim is to provide as much wild wood as possible.

Inside the heat insulating sheet 4 and the felt 5, the fibrous structure remains intact and breathability is maintained. That is,
The bonding surface between the heat insulating sheet 4 and the felt 5 is bonded at the intersection of the linear glass fibers on the surface of the heat insulating sheet 4 and the fibers on the surface of the felt 5, so the bonding surface of the heat insulating sheet 4 is and felt 5
There is no adhesive film formed that blocks the voids between the insulation sheet 4 and the felt 5, and the voids between the heat insulating sheet 4 and the felt 5 are continuous, and sufficient air permeability remains even after the two are laminated. It is.

乾燥させる点に於いても効果的である。 In addition to vinyl acetate emulsion, the adhesives used to bond the roofing board and the insulation sheet, and the insulation sheet and the surface layer, include natural rubber, synthetic rubber, polyurethane, and vinyl acetate emulsion.
Vinyl-based, phenol-based, etc. can be used, and it is not necessarily necessary to apply it to the entire surface, for example, it may be applied in a grid pattern or striped pattern. In this way, the area of the adhesive film will be reduced. As will be described later, it is also effective in drying the sheathing board without preventing moisture evaporation from the back side of the shedding board.

Thatched in sequence.
（考案の効果）
本考案野地材においては、野地板の裏面に断熱
シートが取着されているので、屋内側、屋外側の
気温に温度差があつても野地板の表裏両面の温度
差が小さくなり、特に、瓦に含まれている水分が
冬季に凍結しても屋内からの熱で融解されること
がなく、凍結・融解が反覆して瓦に割れを生ずる
ことが避けられる。(Effects of the invention) In the field material of the present invention, a heat insulating sheet is attached to the back side of the field board, so even if there is a temperature difference between the indoor and outdoor sides, the temperature difference between the front and back surfaces of the field board is maintained. In particular, even if the moisture contained in the roof tiles freezes in the winter, it will not be melted by heat from indoors, and repeated freezing and thawing processes can prevent cracks in the roof tiles.
更に、該断熱シート表面には吸湿性を有する表
面層が設けられているため、浴室、台所等から上
昇してきた余分の水蒸気は表面層に吸収され、垂
木、束、梁等の木材に結露したり、吸収されるこ
とが殆ど無くなり、木材の腐食を防ぎ寿命を永く
することができる。また、余分の水蒸気は野地板
に達するまでに表面層に吸収されるので、野地板
は水蒸気によつて湿ることがなく、野地板自体の
断熱性を低下させることがない。 Furthermore, since the heat insulating sheet has a hygroscopic surface layer, excess water vapor rising from bathrooms, kitchens, etc. is absorbed by the surface layer and condenses on wood such as rafters, bundles, beams, etc. This eliminates most of the damage and absorption, which prevents wood from corroding and extends its lifespan. Further, since excess water vapor is absorbed by the surface layer before reaching the shedding board, the shedding board is not dampened by water vapor, and the insulation properties of the shedding board itself are not reduced.
また、仮に防水シートから雨水が漏れて野地板
に吸収された場合、野地板上面には防水シートが
あるので湿つた野地板は容易に乾燥せず、断熱性
が極めて悪くなるが、裏面の断熱シートは繊維か
らなるため通気性があり、且つ該断熱シート表面
には吸湿性の表面層があるため、屋内側の空気が
乾燥したとき、野地板裏面から蒸発した水分は通
気性のある断熱シートの繊維間の間隙を通り表面
層に吸収され、野地板は乾燥されて断熱性は回復
する。 In addition, if rainwater leaks from the tarpaulin and is absorbed by the roof board, the wet roof board will not dry easily because there is a waterproof sheet on the top surface of the roof board, and the insulation will be extremely poor, but the insulation on the back side will be Since the sheet is made of fibers, it is breathable, and the surface of the insulation sheet has a hygroscopic surface layer, so when the air on the indoor side becomes dry, the water that evaporates from the back of the roof board is absorbed by the breathable insulation sheet. It passes through the gaps between the fibers and is absorbed into the surface layer, drying the roofing board and restoring its insulation properties.
一方、屋内側の空気が過乾状態になつた場合、
表面層に吸収されていた水分は屋内側へ蒸発し、
屋内側の空気に適度の湿気を与え、過乾による木
材の歪を防止し、火災の危険を減少させる。そし
て表面層は乾燥し再び吸湿性を備えるのである。 On the other hand, if the indoor air becomes overly dry,
The moisture absorbed in the surface layer evaporates indoors,
Adds appropriate humidity to the indoor air, prevents wood from warping due to overdrying, and reduces the risk of fire. The surface layer then dries and becomes hygroscopic again.
更に、断熱シートは耐熱性のある材料から製せ
られているので火災に対し、防火作用をなすもの
である。 Furthermore, since the heat insulating sheet is made of a heat resistant material, it has a fire prevention effect.
