Abstract: A modular infill panel system for attaching to vertical structural members of a building frame and adjacent modular infill panel units. The modular infill panel system is capable of creating piecewise curves in the vertical plane as well as complex piecewise three-dimensional curves in a combination of horizontal and vertical planes. The modular infill panel system can include vertically stacked modular infill panel units. The modular infill panel units can be vertically aligned and attached to the building's structural columns by bracket assemblies mounted along one or more outside edges of the top frame member of the structural frame of the modular infill panel units. The bracket assemblies can secure the modular infill panel unit to the vertical structure of the building and alignment pins projecting upward from the bracket assemblies can align vertically adjacent modular infill panel units.

Abstract: A system for ventilating the cavity of a fixed or movable window or door construction of a building, the window or door having an upper sill or header and a low sill provided with weep holes and a pair of jamb elements, the system comprising a vent member operative associated with the upper sill portion, the vent member is in fluid communication with the upper sill at one end thereof and also with the interior of the building at an opposite end thereof, the vent member extends vertically above the upper sill a distance sufficient to vent pressure within the cavity to the interior of the building so that water is caused to be readily conveyed out of the weep holes regardless of any pressure differential between the interior and exterior of the building.

Abstract: A clamping assembly for attaching loads to various kinds of flanged seams, the assembly comprising a generally U-shaped clamp body, at least one clamping hammer disposed interior of the clamp body, the clamping hammer being hingedly secured to the clamp body along the longitudinal axis of the clamp body, at least one adjustment screw extending through the clamp body and adapted to selectively impinge against the clamping hammer and cause it to pivot about its axis, the adjustment screw extending transverse to the longitudinal axis of the clamping hammer, at least one locking screw adapted to selectively impinge against the clamping hammer to prevent pivoting of the same whereby a standing seam received within the clamp body may be tightly grasped between the clamp body and the clamping hammer under action of the adjustment screw and then locked into place by the locking screw.
