SEAL STRUCTURE, METHOD FOR CONSTRUCTING SEAL STRUCTURE, AND METHOD FOR IMPROVING SEAL STRUCTURE
To improve refractory performance and fire retardant performance to suppress deterioration of watertight performance after fire disaster, in a seal structure, a method for constructing the seal structure and a method for improving the seal structure.SOLUTION: In a seal structure in which a through hole is provided in a wall part of a structure and that has a seal part for connecting the wall part and a through member inserted through the through hole, the seal part comprises a watertight part having watertightness, and a flame shielding part having flame retardancy arranged on at least one side in the penetrating direction of the through hole in the watertight part.SELECTED DRAWING: Figure 1
【課題】シール構造およびシール構造の施工方法、シール構造の改善方法において、耐火性能および難燃性能の向上を図ることで、火災後の水密性能の低下を抑制する。【解決手段】構造物の壁部に貫通孔が設けられ、前記壁部と前記貫通孔に挿通される貫通部材とを連結するシール部を有するシール構造であって、シール部は、水密性を有する水密部と、水密部における貫通孔の貫通方向の少なくとも一方側に配置されて難燃性を有する火炎遮蔽部とを備える。【選択図】図１
