Definitions

  • the invention relates to a closable fire protection opening for drywall, comprising a plate having an opening and a lid for covering the opening, wherein the plate has an opening edge delimiting the opening and the lid has a lid edge, and a fire protection cover. See for example NL 1006 870 C1 . EP 1 279 779 A2 . US Pat. No. 7,650,722 B1 ,
  • Drywall systems allow the construction of interior design structures, such as walls and ceilings.
  • Industrial semi-finished products such as plasterboard and metal profiles, are used in dry construction.
  • non-load-bearing interior walls, partitions and ceiling structures, such as suspended ceilings can be produced inexpensively and quickly.
  • These constructions often include installations, such as electrical, ventilation and plumbing installations. These are hidden in the drywall system upon completion of the design.
  • inspection openings are known, which are provided in a wall or ceiling and allow a view and intervention in the interior of the construction. These inspection openings usually have a lid, which is connected via a hinge with a frame. If fire protection requirements are to be met, fire protection openings are provided instead of the inspection openings.
  • Known fire protection openings have an inspection opening as described above, wherein the inspection opening provided with an additional fire protection cover is that covers the opening in addition to the flap.
  • the invention has for its object to develop a sealable Brandtiköffriung that is easy to manufacture and inexpensive and has a low weight.
  • a positive connection between the opening edge and the lid edge is formed such that the lid is held in the assembled state in the opening.
  • the fire protection cover rests on a frame associated with the plate.
  • the fire protection lid closes the opening in addition to the lid, so that the lids are arranged in series and constitute an obstacle to flue gases. Due to the positive connection, the cover automatically holds in the opening, with no additional holding elements are required. In particular, when using the fire protection opening in a ceiling construction, the lid automatically holds due to gravity in the opening. Because no additional holding elements or the like are required, the fire protection opening has only a very few components, namely, in the simplest embodiment, essentially only the plate with the frame, the lid and the fire protection lid.
  • An additional stiffening frame for stiffening the fire opening and for receiving hinges and fasteners for the lid can be omitted.
  • the fire opening is particularly simple and inexpensive to produce and it has a special low weight.
  • the positive connection results only by the shape of the plate and lid, so that additional interlocking elements can be omitted.
  • Another advantage of the lockable fire opening according to the invention is its low height. The height of the fire opening is determined by the height of the plate, frame and mounted fire protection cover. As a result, the fire opening can also be used where only very limited space is available.
  • the plate and the lid may each have a first and a second main side, and the opening edge may be formed such that the cross-sectional area of the opening on the first main side is smaller than the cross-sectional area of the second main side.
  • the lid edge is formed so that the cross-sectional area of the lid on the first main side is smaller than the cross-sectional area on the second main side.
  • the cross-sectional area of the first main side of the opening corresponds to the cross-sectional area of the first major side of the lid
  • the cross-sectional area of the second major side of the opening corresponds to the cross-sectional area of the second major side of the lid.
  • the opening edge and the lid edge may be formed congruent to each other. This results in a particularly secure positive connection, so that the lid is held securely on the one hand in the opening and on the other hand not tilted in the opening. It is also advantageous that only a small gap between the plate and lid forms.
  • the opening edge and the lid edge can be profiled, wherein the profiling is designed such that the opening edge and the lid edge in cross-section at least partially overlap each other.
  • at least one or more lugs can be formed from the opening edge and / or the lid edge.
  • a nose is formed circumferentially.
  • the noses can be provided with different radii. This results in a large overlap and thus a secure hold for the lid.
  • the opening edge and the lid edge may be formed as a slope. Such a shape is particularly easy to produce.
  • at least one step is formed from the opening edge and the lid edge.
  • the cover engages in a defined manner in the opening and can not tilt.
  • Opening edge and lid edge may also be formed so that several or all of the aforementioned design elements are combined.
  • the above-described embodiments each have the advantage that the lid is flush with the plate and the lid in particular does not protrude beyond one of the two main sides of the plate. Furthermore, the joint, which is formed by the opening edge and the edge of the lid, in this embodiment, particularly smoke-tight because a kind of labyrinth results.
  • the opening and the lid may be triangular, rectangular or polygonal. Triangular lids are particularly handy and rectangular openings make hidden installations particularly easy to access. For rectangular openings and lids, especially if they are not square, the lid can be easily removed through the opening.
  • straight sections may be provided and the straight sections of plate and / or lid may be connected by rounded sections.
  • the straight sections When using brittle materials there is an increased tendency to fracture in sharp-edged section, especially when straight section and an acute angle meet.
  • the straight sections are connected by rounded sections. These rounded sections are radiused.
  • the radius is between 1cm and 10cm. Radii in this area reduce the tendency to break without reducing the opening too much.
  • the opening and the cover may each have a circular or an oval basic shape.
  • a circular configuration the acute-angle meeting of straight sections is avoided, which is particularly relevant when using brittle materials such as gypsum. These have a greatly increased tendency to break especially in sharp corners.
  • the height of the frame is selected so that there is a mounting space between the plate and the fire protection cover when the fire protection cover is applied.
  • To close the fire opening it is necessary to first hang the fire protection cover on the frame. Due to the height of the frame remains after placing the fire protection cover mounting space between the plate, frame and fire cover, so that the lid can be inserted through the opening in the room and then placed in the opening.
  • the height of the mounting space corresponds at least to the height of the lid.
  • the handling improves during the application of the lid. Quadrangular or oval lid and opening shapes are particularly suitable for this embodiment, since in these embodiments the lid can be moved through the opening.
  • the frame may be spaced from the opening on the plate: that is, there is a clearance between the opening edge and the inside of the frame such that the cross-sectional area defined by the inside of the frame is greater than the cross-sectional area defined by the opening.
  • the limited by the inside of the frame cross-sectional area should be at least chosen so that an inserted through the opening lid can be rotated with the fire protection lid in the mounting space.
  • the clear distance between the opposite inner sides of the frame corresponds to at least the longest diagonal extension of the lid.
  • the frame and the fire cover space by the space expands parallel to the plate plane. This makes it possible to rotate a lid inserted through the opening in spite of the fire protection cover in the available space, so that the lid can be oriented in the correct position for opening.
  • the fire protection cover can be multi-part. As a result, the fire cover is handy and it can be easily removed from the frame and placed on both sides of the opening in order to achieve the hidden installation through the opening can.
  • the fire protection cover may have two cover parts which are arranged side by side on the frame and partially overlap each other along the contact joint. This is the result Fire protection cover particularly handy and smoke-tight.
  • the seal can be further improved by inserting a fire seal as described above.
  • the fire protection cover can be multilayered.
  • the overlapping contact joint is particularly easy to produce by the plates, which form the lid parts have different dimensions, so that a plate of a lid part overlaps another plate of the other lid part. It is also conceivable to add the plates offset from each other.
  • a multi-layered, for example, two or more gypsum plasterboard, formed fire protection cover also has a higher fire protection than a single-layer fire protection cover.
  • Frame, lid and fire protection cover are preferably made of non-combustible materials, in particular plasterboard, gypsum fiber boards, mineral fiber boards and / or cement materials and / or metallic materials, especially in sheet form.
  • non-combustible materials in particular plasterboard, gypsum fiber boards, mineral fiber boards and / or cement materials and / or metallic materials, especially in sheet form.
