Movement control screed
View Patent ↗Various embodiments of the present invention are directed to a movement control screed that is structured for installation between first and second masonry coatings applied adjacent to a building wall. The movement control screed is structured as a control joint for absorbing movement between the first and second masonry coatings and also as a weep screed for accommodating drainage of water from behind the masonry coatings. The movement control screed comprises first and second flanges provided on opposite sides of first and second ribs.
1. A movement control screed structured for installation between first and second masonry coatings applied adjacent a building wall, wherein the first and second masonry coatings are subject to movement relative to each other, the movement control screed comprising: a first flange defining a substantially non-perforated surface; a second flange defining a substantially perforated surface; a first rib disposed between the first and second flanges, the first rib defining a screed surface positioned adjacent at least a portion of the first masonry coating when the first masonry coating is applied, wherein the substantially non-perforated surface of the first flange and the screed surface of the first rib combine to define a moisture path adapted to direct water from behind the first masonry coating and away from the building wall; and a second rib disposed between the first and second flanges, the second rib defining a screed surface positioned adjacent at least a portion of the second masonry coating when the second masonry coating is applied, wherein the movement control screed is structured such that the first flange is deflectable relative to the second flange for supporting the first and second masonry coatings during relative movement; and wherein the first rib defines a first screed depth corresponding to a first masonry coating thickness and the second rib defines a second screed depth that is smaller than the first screed depth and corresponds to a second masonry coating thickness.
2. The movement control screed of claim 1 , wherein the first screed depth ranges between 0.5 and 2 inches and the second screed depth ranges between 0.25 and 1.875 inches.
3. A movement control screed structured for installation between first and second masonry coatings applied adjacent a building wall, comprising: a first flange defining a substantially non-perforated surface structured for positioning adjacent a first portion of the building wall; a second flange defining a substantially perforated surface structured for positioning adjacent a second portion of the building wall; a first rib disposed between the first and second flanges, the first rib defining a first screed depth that corresponds to a first masonry coating thickness, wherein the substantially non-perforated surface of the first flange combines with the first rib to define a moisture path adapted to direct water away from the building wall; and a second rib disposed between the first and second flanges, the second rib defining a second screed depth that corresponds to a second masonry coating thickness, wherein the first screed depth differs from the second screed depth; and wherein the first screed depth is larger than the second screed depth.
4. The movement control screed of claim 3 , wherein the first screed depth ranges between 0.5 and 2 inches and the second screed depth ranges between 0.25 and 1.875 inches.
