AIRTIGHT MATERIAL AND AIRTIGHT STRUCTURE OF BUILDING
To provide an airtight material capable of increasing the airtightness of a building and an airtight structure of the building.SOLUTION: The present invention relates to an airtight material 1 and an airtight structure of a building. The airtight material 1 includes a base material made of plastic cardboard. The base material 14 includes a deformable portion 20, a first portion 21 located on one side of the second direction with respect to the deformable portion 20, and a second portion 22 located on the other side of the second direction with respect to the deformable portion 20. The deformable portion 20 includes a plurality of cutting portions 25 penetrating the base material 14 on a bending line L1 and an uncut bending rigidity lowering portion 26 located between the cutting portions 25. The bending rigidity lowering portion 26 is formed on the second portion 22 side of the bending line L1, such that the cut end surface 21C facing the cutting portion 25 of the first portion 21 is located closer to the second portion than the bending line L1 when the first portion 21 is bent along the bending line L1.SELECTED DRAWING: Figure 2
【課題】 建物の気密性を高めることが可能な気密材、及び、建物の気密構造を提供する。【解決手段】 気密材1及び建物の気密構造である。気密材1は、プラスチックダンボールで形成された基材を含む。基材14は、変形容易部20と、変形容易部20に対して第2方向の一方側に位置する第1部分21と、変形容易部20に対して第2方向の他方側に位置する第2部分22とを含む。変形容易部20は、折り曲げラインL1上で基材14を貫通する複数の切断部25と、切断部25の間に位置する非切断の曲げ剛性低下部26とを含む。曲げ剛性低下部26は、第1部分21を折り曲げラインL1で折り曲げたときに、第1部分21の切断部25に面する切断端面21Cが折り曲げラインL1よりも第2部分の側に位置するように、折り曲げラインL1よりも第2部分22側に形成されている。【選択図】図2
