CUT-OFF STRUCTURE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cut-off structure capable of exerting cut-off performance requiring a cut-off material, even when a distance between a sash and an exterior wall varies in a width direction of a joint.SOLUTION: A cut-off structure makes preformed sealing materials 30 and 32 compressed in a depth direction of a horizontal joint 94 to seal the horizontal joint 94. Thus, even when a distance between a sash 50 and a lower wall 84 varies in a width direction (vertical direction) of the horizontal joint 94, a compressive force applied to the preformed sealing materials 30 and 32 is hardly changed so that the preformed sealing materials 30 and 32 can exert necessary cut-off performance.SELECTED DRAWING: Figure 7
