Abstract: A reusable window buck or pouring frame for forming a window opening in a cast concrete wall or the like is provided. The window buck comprises an inner and outer rectangular frame in which the inner frame is adapted to be at least partially received in mating relationship within the outer rectangular frame. Releasable clamp means are provided for releasably securing the inner and outer rectangular frame structures together as a substantially interlocked unit.

Abstract: A security sleeve for facilitating the mounting of plumbing fixtures in fire rated masonry or concrete wall construction. The sleeve has a pair of metal plates which are spaced apart about the thickness of the wall. The plates have a plurality of holes which correspond with a plurality of conduits bridging the metal plates to form passageways for plumbing pipes and fasteners connected to the plumbing fixture.

Abstract: A fire resistant, elevator hatchway door entrance for wall openings up to and including 10 feet in height, including first and second side jambs and a head jamb. Each side jamb includes a pair of upstanding, oppositely facing, metallic channel members dimensioned and coupled together to define both a structural box beam and a pocket for receiving the wall which defines the opening. The bight and one leg portion of one channel member define the jamb depth and reveal, respectively, of the side jamb, and the bight of the other channel member receives and shields an asociated J-strut at the wall-entrance interface. The remaining leg portion of the one channel member may cooperate with a member disposed on the trailing edge of the associated door panel to define a flame shield and a mechanical limit for preventing undue separation of the door panel from the side jamb.

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 decorative jamb structure for a side of an entranceway through a wall from a corridor to an elevator hatchway that has a sliding door in the hatchway. The jamb structure includes a shroud covering the end of the wall, the shroud having vertical side elements and a recessed connecting web that define a vertical central channel, a decorative panel removably mounted in the channel by means of headed studs impaling vertical keyhole openings in the web, and a base plate in the channel which is detachably secured to the web and supports the decorative panel with the studs in the narrow upper end portions of the keyhole openings.

Abstract: A quickly assembled door frame formed of sheet metal and having a generally U-shaped cross-section, one of the frame members being adapted to mount a hinge having a portion embossed to provide a recess to receive a plate of the hinge, a plurality of slots provided in a side wall, and a hinge anchor plate having engagement tabs adapted to be inserted into the slots and having threaded apertures adapted to engage screws engaging the hinge plate and passing through apertures provided in the frame member. In an improved embodiment secondary embossments are provided in the frame member defining alignment channels, and the hinge anchor plate is provided with guide tabs adapted to be received within channels, thereby maintaining the engagement tabs of the hinge anchor plate in engagement with the inner wall of the primary embossment.

Abstract: An adjustable bracket for mounting a jamb to an adjacent framing member. The mounting assembly comprises at least one L-shaped member, an inner leg of which is secured to the back of the jamb. The outer leg of the member can be nailed to the surrounding framing to locate and support the jamb.In one embodiment, a pair of telescoping L-shaped members are provided, one of which is secured to the jamb while the other slides within it. The members are advantageously formed with stiffening means at the apexes, and can be formed with detents for engaging the opposite edges of a hollow molding strip.In another embodiment, the brackets engage one side of the molding strip, the other side thereof being forced into a slot extending along the door jamb. A retainer is described which aids in retaining the molding lip in the jamb slot.
