L-Bead: a leak prevention system for stucco surfaces

摘要

A stop bead for mounting along a frame or jamb of a window or door of a building to separate the frame or jamb from plaster or stucco material during application of the plaster or stucco material to the building comprises a first side end portion and a second side end portion, the first side portion having a leading edge for engaging the frame or jamb when the stop bead is mounted adjacent to the frame or jamb, a base panel having a front face, a stop bead wall formed on the base panel and extending outwardly above the front face of the base panel, the stop bead wall having an engaging surface for engaging plaster or stucco and a frame/jamb facing surface that faces the frame or jamb when the stop bead is mounted adjacent to the frame or jamb, and a spacing member formed on the stop bead and extending outwardly away from the frame/jamb facing surface of the stop bead wall for spacing the stop bead wall a predetermined distance from the frame or jamb when the stop bead is mounted adjacent to the frame or jamb, the spacing member forming the leading edge of the first side portion of the stop bead and forming gap between the stop bead wall and the frame or jamb when the stop bead is mounted adjacent to the frame or jamb for receiving caulk for sealing between the stop bead and the frame or jamb. In a preferred embodiment, the spacing member is flexible to permit movement of the spacing member responsive to movement to weather induced movement of the jamb after the stop bead is mounted adjacent to the jamb.

主权项

1. A wall,
the wall having a jamb formed therein, the jamb being part of a frame that frames an opening in the wall, and the jamb having a first surface facing the opening in the wall and a second surface facing away from the opening in the wall, a stop bead mounted on the wall against the second surface of the jamb to separate the jamb from plaster or stucco material during application of the plaster or stucco material to the wall, the stop bead comprising a first side end portion and a second side end portion, the first side end portion having a leading edge engaging the second surface of the jamb when the stop bead is mounted adjacent to the jamb, a base panel having a front face, a stop bead wall formed on the base panel and extending outwardly above the front face of the base panel, the stop bead wall having a first side and a second side, the first side of the stop bead wall having an engaging surface for engaging plaster or stucco material, and the second side of the stop bead wall having a jamb facing surface that faces the second surface of the jamb when the stop bead is mounted adjacent to the jamb, and a spacing member formed on the stop bead and extending outwardly away from the jamb facing surface of the stop bead wall spacing the stop bead wall a predetermined distance from the second surface of the jamb when the stop bead is mounted adjacent to the jamb, the spacing member forming the leading edge of the first side end portion of the stop bead, the leading edge having a jamb engaging surface engaging the second surface of the jamb when the stop bead is mounted adjacent to the jamb, and the spacing member in conjunction with the jamb and the jamb facing surface of the stop bead wall forming a caulk receiving area above the spacing member and between the second surface of the jamb and the jamb facing surface of the stop bead wall for receiving caulk to seal between the stop bead and the jamb, caulk positioned in the caulk receiving area and contacting the stop bead and the jamb to form a seal between the stop bead and the jamb, and plaster or stucco material applied to the wall and separated from the jamb by the stop bead, the spacing member comprising flexible material and being adapted to permit movement of the spacing member responsive to weather induced movement of the jamb after the stop bead is mounted adjacent to the jamb, and the spacing member being resilient.
