Abstract: A lintel for supporting arches over doors, windows and other openings in a wall. The lintel is made of relatively thin sheet metal and has at least one load-carrying shank (5;12,13;19,20), so that the lintel in spite of its thin construction can carry great loads during the walling of the arch. The shank or each shank is provided with a longitudinally extending material weakening (6), e.g. a series of slots, perforations, a groove or similar. Said material weakening forms a fracture indication along which the shank can be folded or broken off, when the motar has set and brickwork has become self-supporting.

Abstract: A method of insulating a building having a foundation wall disposed at least partially below grade includes substantially covering the exterior surface of the foundation wall with panels of insulation material, securing the panels thereto with flanged retaining members interposed between adjacent edges of adjacent panels. The retaining members are secured to the foundation wall with the flanges thereof partially overlying the adjacent panels. The top edge of the insulation material is then covered to prevent the impingement of water and foreign matter onto the top edge and between the panels and foundation wall.A system for securing panels of insulation material to the exterior surface of a building foundation wall includes a plurality of flanged retaining members, each including a base portion and at least one flange laterally extended from the base portion to overly a panel in abutment with the base portion.

The first web portion is substantially straight throughout its longitudinal direction and the second web portion is curved in the vertical direction towards the plane containing the uppermost elongate flat surface of the first web portion. If desired, the element may include a box-section wherein the second web portion comprises the top wall thereof.

Abstract: The invention provides a structural assembly for use in a building comprising an elongate structural element for use in a frame (such as a window or door frame) in an opening in the wall of the building, said structural element providing an effective pocket open along one side thereof, and a sill which comprises an elongate plate-like element formed along its inner edge with an arcuate surface as seen in transverse section, whereby said sill is adapted for rocking motion about its inner edge, said inner edge of said sill being received within said pocket and said plate-like element extending laterally from said elongate structural element.

Abstract: Apparatus for mounting awning panels adjacent the roof fascia, having an overlapping roof drip edge includes a header having a first plate adapted to be mounted flush with the fascia and having a flange extending underneath the drip edge. The header is provided with a channel along the upper edge thereof, with a flap having a flange along an edge thereof, the flange of the flap engaging the header in the channel. The other edge of the flap is fastened to the field of the awning panel, and a strip of sealing material is disposed along the interface between the flap and the channel.

Abstract: A building element comprises a rectangular panel having four flanges projecting from one face thereof adjacent to the edges of the panel, wherein the bottom and side edges of the panel each have at least one groove running the length thereof and wherein the flanges are provided with means suitable for, or suitable for use in, the fixing of the building element to another similar or different building element.

Abstract: An energy efficient skylight construction. A skylight cover is secured by a frame to a curbing comprised of an insulating core, the interior and exterior surfaces of which are covered by non-combustible shields separated along the upper and lower surfaces of the curbing by a gap which serves as a "thermal break" between the highly conductive inner and outer shields. The frame is pierced by drain openings the exterior of which are covered by a filter type material such as foam or glass fibers that is both absorbtive of moisture and resistant to the passage of air. The frame is secured to the outward portion of the curbing and includes a flange extending inward across the gap between the shields, which serves as a gutter to collect condensation which drips off the glazing.

Abstract: A sloped curtain wall structure for buildings comprises an elongated, horizontal sill including a bottom wall and at least one upstanding side wall forming a gutter designed for mounting on a supporting base structure such as a vertical wall segment or a foundation wall. An elongated baffle is interconnected with the horizontal sill and is interlocked with side walls to substantially enclose the sill above the gutter and a plurality of rafters are connected through openings in the baffle by extruded anchors to the sill and supporting structure and slope upwardly to support glazing panels mounted in the frame work. Each rafter includes a gutter and a glazing pocket aligned with the glazing pocket in the baffle for receiving and supporting the edges of a glazing panel.

Abstract: A rainwater run-off dispersion system comprising mounting means and receiving surface with a plurality of fixed baffles, spaced tangentially at the roof edge of a building in the path of rainwater falling therefrom and preferably inclined outwardly and downward away from said building, said baffles uniformly distributing and dispersing rainwater away from same building and breaking up same into a relatively fine and dispersed shower of droplets.

Abstract: An exterior window unit for covering the outside of an opening in a building wall. The unit has a frame header comprising a vertical mounting plate, a first horizontal plate projecting outwardly from the mounting plate, a second horizontal plate projecting outwardly from the mounting plate and spaced upwardly of the first horizontal plate, and a slanted surface extending downwardly from said second to said first horizontal plate. The second horizontal plate has at its outer end a drip flange projecting downwardly therefrom.

Abstract: There is provided an improved wall construction including a vertical mullion and a horizontal member. The horizontal member is provided with longitudinally extending screw splines. The members may be assembled in the known shear block method, or in a known screw spline system, or further in accordance with the present invention the members may be assembled in accordance with an improved shear pin system. The shear pin system employs a shear pin which joins the horizontal member to the vertical mullions. The vertical mullion is prepared for the attachment of a horizontal member by forming holes to receive the head of a shear pin, and the horizontal member is prepared by the insertion of the shear pins into screw splines formed in the horizontal member. The horizontal member is then installed on the vertical by installing the head of the shear pin into the hole previously drilled in the vertical mullion, and then tapping the horizontal downward until the shear pins bottom in the holes.

Abstract: A protective cover for a stack of hay bales is provided, the cover comprising a plurality of panels, each of generally shallow inverted V-shape configuration. The panels are disposed side-by-side on the stack with their adjacent edges overlapping. Each panel is provided with a plurality of anchors which project downwardly and engage between certain ones of the bales thereby to assist in preventing the panels from being carried away by the wind.

Abstract: A metal roof unit including a backing, a heat insulating material, and a surface metal plate, which can be produced by roll forming, press forming or extrusion forming on a mass-production basis in factories and can be used for roofing without special skill by expert roofers. In order to unite the metal roof units there are provided joint members which can be produced of light metal such as aluminum by roll forming, press forming or extrusion forming. The joint members are provided with a series of slits from which nails are driven through notches provided at each ends of said metal roof units into a rafter which is provided under said metal roof units, and said slits and notches have sufficient allowance in order to make the joint members and metal roof units movable by heat expansion due to sun heat.

Abstract: A rain water run-off disperser comprising mounting means, and multiple fixed deflecting surfaces spaced below a roof edge of a building in the path of water falling therefrom and preferably inclined downwardly and outwardly from said building, said deflecting surfaces deflecting water away from said building and breaking up the same into a relatively fine and dispersed shower of drops.
