Abstract: Tie beam formation apparatus includes parallel opposed sidewalls defining a channel constructed to receive concrete for the formation of a tie beam. The sidewalls are disposed to become a fixed part of the tie beam. The apparatus further includes mounting structure attached to the sidewalls for holding the sidewalls in the channel defining position. The mounting structure is designed to hold the sidewalls on an upper surface of a block wall and to engage the sidewalls with the block wall at regular intervals. The mounting structure is further designed to allow a flow of concrete into openings in the block wall at spaced apart regular intervals.

Abstract: A window sill includes a metal form having inner and outer surfaces and a shape defining an inner space. The window sill also includes a fill piece positioned in the inner space so that an upper surface of the fill piece is adjacent to and forms a seal with the inner surface of the metal form. The window sill further includes a window assembly for holding a pane of glass. The window sill is positioned on and forms a seal with the outer surface of the metal form.

Abstract: A box lintel includes an elongated, hollow metal form with a lower wall, integrally formed side walls extending upwardly therefrom, and integrally formed partial upper walls extending inwardly from the side walls. A method of fabricating a box lintel is also disclosed which includes the steps of providing an elongated flat sheet of metal and bending the flat sheet of metal into a hollow metal form with a lower wall, integrally formed side walls extending upwardly therefrom, and integrally formed partial upper walls extending inwardly from the side walls. The form is adapted to be positioned on upright masonry supports so as to span an opening and to be filled with grout/mortar and to receive one or more courses of masonry bricks on the upper walls.

Abstract: A prefabricated lintel having two spaced apart parallel upstanding legs extending along the length of the lintel and having laterally aligned holes defined therethrough and spaced therealong. The lintel further has a flat lower surface and an upper surface defining flat, horizontal shoulders positioned along outer edges of the lintel on opposite sides of the upstanding legs and extending the length of the lintel. The lintel is placed to span a doorway and a course of blocks is laid on the flat shoulders, with a second course laid on the first course and a rebar positioned on the upper surface. A plurality of wire stirrups, each defining a rebar receiving loop, are engaged over the rebar and extend through openings in the two courses with end portions of the stirrups engaged in each of the holes defined in the upstanding legs of the lintel. The block openings are filled with grout.

Abstract: A lintel system includes a steel flange plate adapted to rest on the wall adjacent both sides of an opening to be spanned, a steel reinforcing structure integral with the flange plate and steel primary reinforcing rods welded to the reinforcing structure and extending upwardly. After the flange plate has been emplaced, two courses of masonry blocks are laid to encompass the primary reinforcing rods. Different embodiments of the invention employ different upper structures. In a first embodiment, a wooden beam directly overlays the upper plate, and each includes apertures generally aligned with and larger than the primary reinforcing rods, each of which is threaded to receive a nut along its terminal portion such that the nuts may be tightened to compress the lintel system into a rigid structure. In the second embodiment, the lintel system also includes secondary reinforcing rods welded to the lower face of the upper plate and extending downwardly into the interior space of the masonry blocks.

Abstract: Side panels, terminating with inwardly directed flanges extend from the vertical edges of an upright main panel to form a generally channel shaped unit. The lower edge of each side panel is spaced above the lower edges of the main panel and the flanges to receive a conventional sill. A bearing plate extends inwardly from the lower edge of each side panel to rest upon the top of the sill. The upper edges of the side panels and the flanges terminate below the upper edge of the main panel to form a ledge for supporting a conventional beam. A recess, formed in the upper corner of the main panel, accommodates the beam and has a beam attachment plate extending therefrom.
