Description

本発明は、隅部用長尺気密シートに関する。   The present invention relates to a long airtight sheet for corners.

住宅等の建物の気密性を高いものにするため、壁と床の取り合い部や、壁と天井の取り合い部等に、気密材が設置されるが、気密材の設置は、従来、気密テープを用いこれを取り合い部にＬ形にして貼り付けたり、あるいは、取り合い部にシーリングを施したり、あるいは、気密シートを取り合い部においてＬ形に貼り伸ばししたりすることで行われることもあるが、これらの方法は、品質が現場での施工精度に依存してしまうことや、施工に技量を要することなどから、現在では、予めＬ形に成形した樹脂製の長尺気密シートを用い、これを取り合い部に設置するという方法で行うのが主流となっている。   In order to increase the airtightness of buildings such as houses, airtight materials are installed at the joints between walls and floors, and between walls and ceilings. It may be done by applying this to the joint part in an L shape, or by sealing the joint part, or by sticking and extending an airtight sheet to the joint part in an L shape. This method is based on the accuracy of construction on site and requires skill in construction. Currently, we use a resin-made long air-tight sheet molded in advance in an L-shape. The mainstream method is to install it in the club.

しかしながら、気密シートはそもそも非常に薄くつくられるものであるため、予めＬ形に成形した長尺気密シートは、腰が弱くてＬ形の直角がでにくい等の理由から、いささか施工しずらい面がある。   However, since the airtight sheet is made very thin in the first place, the long airtight sheet molded in advance in the L shape is a little difficult to construct because of its low waist and difficulty in making the right angle of the L shape. There is.

本発明は、上記のような問題点に鑑み、薄肉にもかかわらず、Ｌ形部の直角をしっかりと出すことができ、現場での施工を容易に行うことができる、横断面にＬ形部を備えた隅部用長尺気密シートを提供することを課題とする。   In view of the above-mentioned problems, the present invention can firmly bring out the right angle of the L-shaped portion despite being thin, and can be easily constructed on site. It is an object to provide a long airtight sheet for corners provided with

上記の課題は、横断面にＬ形部を備えた隅部用長尺気密シートであって、
前記Ｌ形部に、その屈曲部を挟む一方の側から屈曲部を通じてもう一方の側に連続して延びる線状の補強リブが、シート長手方向に複数、間隔的に備えられていることを特徴とする隅部用長尺気密シートによって解決される。 The above-mentioned problem is a long airtight sheet for corners having an L-shaped portion in a transverse section,
The L-shaped part is provided with a plurality of linear reinforcing ribs extending continuously from one side across the bent part to the other side through the bent part in the longitudinal direction of the sheet. This is solved by the long airtight sheet for corners.

この気密シートでは、Ｌ形部において、その屈曲部を挟む一方の側から屈曲部を通じてもう一方の側に連続して延びる補強リブが備えられているので、シートが薄肉であっても、該リブの補強作用によってＬ形部の直角がしっかりと出る。そして、該補強リブは、線状をしていて、シート長手方向に複数、間隔的に備えられているので、気密シートが長尺であっても、長さ方向の各部においてＬ形部の直角がしっかりと出て、現場での施工を容易に行うことができ、しかも、気密シートとしての薄さが補強リブによって妨げられることもない。   In this airtight sheet, since the L-shaped portion is provided with reinforcing ribs that continuously extend from one side sandwiching the bent portion to the other side through the bent portion, even if the sheet is thin, the rib The right angle of the L-shaped part comes out firmly by the reinforcing action. The reinforcing ribs are linear, and a plurality of the reinforcing ribs are provided at intervals in the longitudinal direction of the sheet. Therefore, even if the hermetic sheet is long, the right angle of the L-shaped part in each part in the longitudinal direction. Can be firmly attached and can be easily constructed on site, and the thinness of the airtight sheet is not hindered by the reinforcing ribs.

上記の気密シートにおいて、横断面に複数のＬ形部が備えられ、各Ｌ形部に前記補強リブが備えられているのもよい。この場合は、各Ｌ形部の直角がそれぞれにしっかりと出て、現場での施工を容易に行うことができる。   In the above airtight sheet, a plurality of L-shaped portions may be provided in the cross section, and the reinforcing rib may be provided in each L-shaped portion. In this case, the right angles of the respective L-shaped portions can come out firmly, and construction on site can be easily performed.

前記補強リブが、シートの一方の面を凹、もう一方の面の凹対応部分を凸に成形して形成されたものからなる場合は、シートが薄肉で、補強リブも薄肉であることにより、施工後は、このリブが潰れることで、補強リブが周囲との取り合い関係で妨げとなることもない。   In the case where the reinforcing rib is formed by forming one surface of the sheet concave and forming the concave corresponding portion of the other surface convex, the sheet is thin and the reinforcing rib is also thin, After the construction, the ribs are crushed so that the reinforcing ribs do not interfere with the surrounding relationship.

本発明は、以上のとおりのものであるから、薄肉にもかかわらず、Ｌ形部の直角をしっかりと出すことができ、現場での施工を容易に行うことができる。   Since the present invention is as described above, the right angle of the L-shaped portion can be firmly brought out despite the thin wall, and the construction at the site can be easily performed.

次に、本発明の実施最良形態を図面に基づいて説明する。   Next, the best mode for carrying out the present invention will be described with reference to the drawings.

図１及び図２に示す第１実施形態の隅部用長尺気密シート１は、図５（イ）に示すように、建物内の床２と壁３との取り合い部分に設置されるもので、横断面にＬ形部を一つ備えたＬ形の気密シートからなっている。該気密シート１は、厚さが例えば０．１ｍｍを下回らない程度の極薄のポリエチレンシートなどからなっていて、図１（イ）に示すように、屈曲部１ａを挟む一方の側１ｂから屈曲部１ａを通じてもう一方の側１ｃに連続して延びる線状の補強リブ４が、シート長手方向に複数、間隔的に備えられている。そして、各補強リブ４は、図１（ハ）に示すように、シート１の一方の面を凹、図１（ロ）に示すように、もう一方の面の凹対応部分を凸とするように、真空成形などにより成形されて形成されたものからなっている。   As shown in FIG. 5 (a), the corner long airtight sheet 1 of the first embodiment shown in FIG. 1 and FIG. 2 is installed at a joint portion between a floor 2 and a wall 3 in a building. It consists of an L-shaped airtight sheet with one L-shaped part in the cross section. The airtight sheet 1 is made of an extremely thin polyethylene sheet having a thickness not less than 0.1 mm, for example, and is bent from one side 1b sandwiching the bent portion 1a as shown in FIG. A plurality of linear reinforcing ribs 4 extending continuously to the other side 1c through the portion 1a are provided at intervals in the sheet longitudinal direction. Each reinforcing rib 4 is concave on one surface of the sheet 1 as shown in FIG. 1 (C) and convex on the concave corresponding portion on the other surface as shown in FIG. 1 (B). Further, it is formed by being formed by vacuum forming or the like.

この気密シート１では、シートが薄肉であっても、補強リブ４の補強作用によってＬ形部の直角がしっかりと出る。しかも、該補強リブ４は、線状をしていて、シート１の長手方向に複数、間隔的に備えられているので、気密シート１が長尺であるにもかかわらず、長さ方向の各部においてＬ形部の直角がしっかりと出、また、気密シートとしての薄さが補強リブ４…によって妨げられることもない。   In this airtight sheet 1, even if the sheet is thin, the right angle of the L-shaped portion is firmly obtained by the reinforcing action of the reinforcing rib 4. Moreover, since the reinforcing ribs 4 are linear and are provided in a plurality of intervals in the longitudinal direction of the sheet 1, each part in the longitudinal direction is provided even though the airtight sheet 1 is long. The right angle of the L-shaped portion is firmly formed, and the thinness as an airtight sheet is not hindered by the reinforcing ribs 4.

上記の気密シート１は、図２（イ）（ロ）及び図５（イ）に示すように、壁３と床２の取り合い部に設置されるが、その施工において、該気密シート１は、上記のように、それ自体でＬ形部の直角がしっかりと出ているので、設置するだけで、屈曲部を挟む各辺１ｂ，１ｃが壁３と床２に沿い、施工を容易に行うことができる。   As shown in FIGS. 2 (a) and 2 (b) and FIG. 5 (a), the above airtight sheet 1 is installed at a joint portion between the wall 3 and the floor 2. In the construction, the airtight sheet 1 is As mentioned above, the right angle of the L-shaped part is firmly on its own, so that it is easy to install by installing each side 1b, 1c sandwiching the bent part along the wall 3 and the floor 2 Can do.
