PROBLEM TO BE SOLVED: To provide a drainage structure that can control drainage in a lower part of a sleeve frame projecting from an exterior wall of a building to suppress adhesion of dirt to the exterior wall, and to provide an architrave having the drainage structure.SOLUTION: A drainage structure 10 is provided in a lower part of each of sleeve frame parts 20c, 20d provided to project from an exterior wall 18 of a building 14 along a vertical direction. The sleeve frame parts 20c, 20d are formed of sections and include lower caps 34a, 34b fitted to cover their lower end surface 38 and having a rising shape covering at least a part of an outer peripheral edge of the lower end surface 38. The lower caps 34a, 34b have therein a drainage path G allowing flow of water by arranging their bottom surface 36f with a gap G between the sleeve frame parts 20c, 20d and the lower end surface 38. Drain ports 48, 49 for discharging water inside the drainage path G to the outside are provided at positions away from the exterior wall 18 of the bottom surface 36f of the lower caps 34a, 34b.SELECTED DRAWING: Figure 5 |
