Weep

Abstract: This invention relates to a metal plate curtain wall structure. The joints of the metal plate structure are sealed weathertight without exposed caulking. A second line defense against water infiltration is formed by a concealed internal drainage system without exposed weep holes eliminating the water stain problem under the weep holes and enhancing the architectural appearance. A plate connection system securely fastened to the structural support is slidable in the direction parallel to the plate surface allowing free thermal expansion of the plate without weakening the resistance against wind load acting normal to the plate surface. The connection system is also designed to absorb any conceivable dimensional tolerance of the support frame facilitating the easiness of field erection.

Abstract: A mortar and debris collection device for a cavity wall construction has a non-water absorbent body formed with circuitous paths therethrough making the body water-permeable. The collection device has a porosity sufficient to permit water to pass therethrough but insufficient to permit mortar and other debris to pass therethrough to weep holes or other water channels covered by the collection debris. The device may be freely placed on the wall base within the cavity to cover the opening of a weep hole, or may also be placed on existing wall ties within the cavity.

Abstract: A self draining door sill assembly for use in the bottom of an exterior door frame of a house or other building is disclosed. The assembly includes an elongated base and a threshold member adjustably attached to the base for cooperating with and engaging a weather strip attached to the underside of a door when the door is closed in the frame to form a primary water seal. The threshold and base define an elongated water chamber therebetween and the threshold defines an upwardly opening storm drain channel formed in and along an upper, interior side surface portion thereof which terminates in a pair of slots located in opposite ends of the threshold, which slots also communicate with the underlying water chamber. A pair of spaced apart weep channels are formed in the base and extend from a floor of the water chamber exteriorally along the through an exterior side of the base, such that rain water which blows or seeps past the primary seal gathers in the drain channel, flows through the slots onto the floor of the water chamber, migrates along the floor to the weep channels, and then flows through the weep channels out of the assembly. A weather cover panel covers an exterior side portion of the base and a compressible resilient gasket is attached to the weather cover and fills a gap between the weather cover and the threshold member.
