Definitions

  • the invention relates to a system for erecting a peripheral frame for a building opening and a frame composed of the components of the system.
  • a peripheral frame for a window opening can also be referred to as a soffit frame or soffit cladding and is a frame which is present on the building side around a window and protrudes over the outer wall, in particular the thermal insulation layer and plaster layer or cladding of the facade, of the building.
  • window also means a French balcony.
  • the frame comprises a sill or sill, two side members and a top member which faces the sill or sill.
  • cladding of window reveals in the form of sheet metal elements or aluminum profiles are known, which are attached to the frame of the window and line the existing reveal of the wall.
  • the cladding elements additionally cover the side walls and the upper surface of the window reveal, so that there is no unified system or unified or uninterrupted frame.
  • the sheet metal elements or aluminum profiles of the reveal elements can protrude slightly from the facade of the building, with the window sill usually protruding further than this. It is also disadvantageous that the load dissipation takes place at least partially on the window frame.
  • metal elements are also screwed to the masonry with metal mounting brackets, with the brackets being attached directly to the metal element and to the wall, which disadvantageously results in a thermal bridge.
  • the object on which the invention is based is to provide an improved frame for a building opening.
  • a system according to claim 1 is proposed for solving the task.
  • the system includes a soffit frame, which is composed of soffit elements and assembly elements and cladding elements, in particular made of sheet metal.
  • the cladding elements preferably include cover elements, which are on the inside of the frame and connection elements, which are on the outside of the frame.
  • the reveal elements are preferably made of heat-insulating material, in particular a hard foam, so that thermal bridges in the area of the reveals are advantageously reduced.
  • the frame or the reveal element are arranged circumferentially around the opening in the building, with the reveal elements adjoining one another directly, so that the opening in the building is surrounded by a border of thermal insulation material.
  • the installation elements with which the reveal elements are fastened to the surface of the wall or the building wall that is parallel to the building opening, result in a force being introduced mainly into the wall or the building wall.
  • the frame Due to the two-layer structure with inner reveal elements and outer cover elements, which are preferably bonded to the reveal elements over a large area, the frame can project far beyond the facade, which increases the design freedom for the building planner.
  • a kit usually contains two or three different soffit elements, with the side soffit elements usually being identical.
  • the upper and lower reveal element can also be identical to one another.
  • One type preferably has a parallelogram cross-section.
  • Another type has a rectangular cross-section.
  • the cross-section can also be wedge-shaped, trapezoidal or triangular, depending on the design wishes of the building planner.
  • the lower soffit member has an upper surface that slopes away from the building.
  • top soffit member has a top surface that slopes away from the building.
  • each soffit member may be parallel to the top surface to form a parallelogram, or skewed to the top surface to form a trapezoid or triangle.
  • soffit members of parallelogram cross-section form the bottom and top members of the soffit frame and soffit members of rectangular cross-section form the side members of the soffit frame.
  • the reveal elements each face the building with a narrow longitudinal edge.
