Definitions

  • This invention relates to lintels and more particularly to a new and improved lintel and method of supporting a course of blocks with a binder above an opening.
  • a post-and-lintel construction is most often utilized for supporting a load above an opening.
  • the post-and-lintel construction has been used all over the world and for centuries ranging from the stone circle at Stonehenge and the Greek architecture of the Parthenon in Athens to present day commercial and residential windows and doorways.
  • Lintels have been constructed from stone, timber, concrete or steel. Each of these materials have positive and negative characteristics when used to construct a lintel.
  • Lintels constructed of stone resist weathering and corrosion may span only very limited distances due to the weight of the lintel and lack of tensile strength.
  • Lintels constructed from timber are capable of spanning further distances than stone lintels, however timber is susceptible to burning and decaying.
  • Concrete lintels may span further than stone lintels and resist burning and decaying unlike timber lintels, however the weight of concrete lintels economically inhibits transportation of concrete lintels over large distances.
  • U.S. Patent 4,020,612 to W. T. Welch discloses a lintel fabricated of an elongated lightweight metal plate having rigidifying beam means affixed thereto and extending longitudinally thereof.
  • U.S. Patent 4,280,308 to L. Svensson discloses 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, 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, e.g. a series of slots, perforations, a groove or similar.
  • the material weakening forms a fracture indication along which the shank can be folded or broken off, when the mortar has set and brickwork has become self-supporting.
  • U.S. Patent 4,409,764 to J. A. Wilnau discloses a system for constructing the structural framework of a building or other structure of reinforced concrete, characterized by column and beam forms of sheet metal which remain in place as permanent parts of the framework after being filled with concrete. These forms are preferably factory-assembled, together with the necessary internal metal reinforcing skeletons, and shipped to the building site ready for erection of the column forms and interconnection thereof by the beam forms. Novel provisions are made, by means of walers and tensioned steel bands, for initially compressing opposed side walls of the forms to concave curvatures so that they are returned to essential flatness by the hydrostatic pressure of the fluid concrete.
  • U.S. Patent 4,757,656 to J. Powers, Jr. discloses a lintel system including 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.
  • 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.
  • 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. Upwardly directed steel studs are welded to the upper face and extend through the apertures in the beam and the top plate such that nuts may be tightened to compress the lintel system into a rigid structure.
  • a charge of mortar is introduced into the space within the masonry block courses to envelop the portions of the reinforcing rods disposed in the space.
  • U.S. Patent 5,465,538 to J. Powers, Jr. discloses 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.
  • U.S. Patent 6,367,209 to J. Powers, Jr. discloses a box lintel including 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.
  • U.S. Patent 6,560,938 to J. Powers, Jr. discloses a box lintel including 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.

Linteau soutenant une portée de blocs assemblés avec un liant au-dessus d'une ouverture définie entre des première et seconde surfaces supports. La portée de blocs comprend des première et seconde parties portantes. Le linteau comprend une base allongée à première et seconde extrémités qui s'étendent entre les deux surfaces supports. Ladite base comporte un haut et un bas, et des premier et second côtés. Une montée s'étend depuis le haut de la base pour augmenter la capacité de charge du linteau. Un premier barrage s'étend vers le haut depuis le premier côté de la base pour recueillir le liant adjacent au premier barrage, et un second barrage s'étend vers le haut depuis le second côté de la base pour recueillir le liant adjacent au second barrage. Les deux parties portantes de la portée de blocs se trouvent au-dessus des deux barrages et le liant ainsi recueilli soutient ces deux parties.
