【考案の詳細な説明】
本考案は木造建築物の外壁となる、モルタル、金属サイ
ディング等の下地とする防水性、通気性壁下地シートに
関する。[Detailed Description of the Invention] The present invention relates to a waterproof and breathable wall base sheet used as a base for mortar, metal siding, etc., for the outer walls of wooden buildings.
近年建造物の壁に断熱材を組み入れて、保温、保冷、省
エネルギーをはかる場合が多い。In recent years, insulation materials have often been incorporated into the walls of buildings to keep them warm, cool, and save energy.
然し壁に断熱材を組み入れると、壁内の換気が悪くなり
木材を早く腐蝕さす傾向がある。However, incorporating insulation into walls tends to reduce ventilation within the walls and cause the wood to rot faster.
殊に冬期石油暖房をする場合、その発生する水分は非常
に多く、内壁６を透した湿気および、屋内、外の温度差
による結露水分が壁内に充満する。Particularly when oil heating is used in the winter, a large amount of moisture is generated, and the walls are filled with moisture that has passed through the inner wall 6 and condensed moisture due to the temperature difference between indoors and outdoors.
従来、壁下地シートとして、屋外より雨水の浸入を防ぐ
目的で、通気性のない又は小さいプラスチックシート、
アスファルト含浸シートの如き防水シートを用いている
ので、断熱材を組み入れた壁内に包含され外部に排出す
るのを遮断され、いつまでも乾燥しない。Traditionally, non-breathable or small plastic sheets have been used as wall base sheets to prevent rainwater from entering from outdoors.
Since a waterproof sheet, such as an asphalt-impregnated sheet, is used, it is contained within a wall that incorporates a heat insulating material, and is blocked from being discharged to the outside, so it does not dry out forever.
その為木材を腐蝕し木造建造物の寿命を著しく短縮する
結果となり、近年業界では此の対策が望まれている。As a result, the wood corrodes and the lifespan of wooden structures is significantly shortened, and in recent years, countermeasures against this problem have been desired in the industry.
本考案は従来のプラスチックシート又はアスファルト含
浸シートの如き通気性のない又は少い壁下地防水シート
の代りに、通気性の多い構造の防水シートを外壁下地に
用い、壁内の湿気を屋外に通気し木材の腐蝕を防ぐ目的
である。This invention uses a waterproof sheet with a highly breathable structure as the exterior wall base instead of a wall base waterproof sheet with no or little air permeability, such as a conventional plastic sheet or asphalt-impregnated sheet, and allows moisture inside the wall to be vented to the outdoors. The purpose is to prevent corrosion of wood.
本考案防水、通気性壁下地シートの構成は、アスファル
ト、フェルトを横方向に、好ましくは２０〜５０ｃｍ間
隔に切断し得られた１ ａ、１ ｂ、Ｉ Ｃ，１ｄを第
１図の如く、重ねしろをとって点接着２する接着しない
部分３は通気が自由な間隙として残して、ａの如く長尺
ロール状に巻き取る。The structure of the waterproof and breathable wall base sheet of the present invention is as shown in Fig. 1: 1a, 1b, IC, 1d obtained by cutting asphalt or felt in the horizontal direction, preferably at intervals of 20 to 50 cm. The overlapping margin is removed and the unbonded part 3 where point bonding 2 is to be made is left as a gap for free ventilation, and the film is rolled up into a long roll as shown in a.
接着剤としては、アスファルトを主材として、合成ゴム
、合成樹脂等を配合したホットメルト型接着剤が好しい
。As the adhesive, a hot-melt adhesive containing asphalt as a main material and synthetic rubber, synthetic resin, etc. is preferable.
又溶剤型接着剤も用いることが出来る、接着作業はコン
ベヤー上の流れ作業で、切断したシーＩ・を点接着して
長尺のシートを形成して巻き取るのがよい。A solvent-based adhesive can also be used.The adhesion work is preferably carried out by point-adhering the cut sheets I in an assembly line on a conveyor to form a long sheet and winding it up.

モルタル塗り又は金属サイテ゛イングである故、その間
隙より排出される。During construction, a heat insulating material 5 is placed on the outside of the inner wall 6 as shown in Figure 3.
Instead of the conventional waterproof sheet used on the outside, the waterproof and breathable wall base sheet A of this invention is used to hang down like an armor and fixed to the crossbars to prevent rainwater from entering from outside and prevent the inside of the wall from entering. Moisture is discharged through the gap 3 as shown in 7. Since the outer wall 4 constructed on the outside thereof is made of breathable mortar coating or metal cladding, the moisture is discharged through the gap.
本考案防水通気壁下地シートはかかる構成よりなるので
、壁内に断熱材を組み入れても乾燥し易く、木材の耐久
性をよくする。Since the waterproof breathable wall base sheet of the present invention has such a structure, even if a heat insulating material is incorporated into the wall, it dries easily and improves the durability of the wood.
且つ断熱材の湿気を排出し易いので断熱効果がよく保温
、保冷、省エネルギーにも有効である。In addition, since the moisture in the insulation material can be easily discharged, it has a good insulation effect and is effective in keeping warm and cold, and saving energy.
