Definitions

  • the invention relates to a plate-shaped fire protection element in sandwich construction with at least three together connected layers, which is subject to fire withstands a front and a back, especially for a ceiling or wall in a building.
  • Such a fire protection element is from DE 40 36 735 C2 known.
  • the legs of the U-shaped Traverse lie on the plates, whereas the Bridge defines the height of the space between the plates.
  • the well-known fire protection element a high density and therefore need one particularly complex and stable support structure for Installation on a ceiling.
  • the overall height of the fire protection element large, what when installed in a Building requires large suspension heights, and the fire protection element is not sound absorbing.
  • a plate-shaped fire protection element is also known, which is bordered with a U-profile, over the entire height of the plate element and around it runs all around. An adjustment of the plate element structural conditions z. B. by shortening is not possible.
  • the present invention is based on the object plate-shaped fire protection element of the type mentioned above to create a high mechanical with low weight Has stability and easy and inexpensive to manufacture and is easy to install in a building.
  • a passage of fire gases through the fire protection element is mainly prevented with the help of the middle layer, with which the two outer layers the weight of the fire protection element can advantageously be reducing porous.
  • Every single solid of the expanded glass granulate or Perlite of the outer layers has a high proportion of pores, which also gives the fire protection element good insulation.
  • the outside sinter plate-shaped layers superficial and thus protect the Layers arranged inside the fire protection element.
  • the equipment of the outer panels with expanded glass granulate or pearlite a high degree of sound absorption guaranteed. This is especially of Advantage if the fire protection element z. B. in corridors and Escape routes from buildings is installed. A halls in these gears are thus avoided.
  • the weight of the fire protection element is particularly low, if preferably at least two of the layers by means of one Adhesive are connected. It is sufficient if the adhesive is only partial, e.g. B. in a grid pattern, is placed between the layers.
  • the adhesive could be flame retardant; the fire protection effect will however, especially reinforced when the adhesive is non-flammable is.
  • the fire protection element is against a passage of Gases particularly dense if according to another advantageous one Development of the invention, the middle layer Gypsum fiber board or a calcium silicate board is. Gypsum fibreboard and calcium silicate plates are also special inexpensive to manufacture.
  • the plate-like layers have the same external dimensions and two or more To install fire protection elements abutting in a building are.
  • the outer edges of the fire protection elements z. B. with a Fire protection compound must be provided, which under the influence of heat, d. H. in the event of a fire, swells or foams and so the area between two fire protection elements closes. Applying the fire protection compound the outer edges of the fire protection element is pronounced complex. It is therefore of particular advantage if the middle layer has smaller external dimensions than the outer layers and if on at least one the middle of the outer edges of the fire protection element Layer forming a recess opposite the outer one Layers is set back. In this recess z. B. a material swelling in the event of fire.
  • the material can be easily inserted into the recess insert because it flows out or away through the groove-shaped Design of the recess is prevented.
  • the manufacture of the fire protection element is preferred as well as its installation in the Recess a spring element insertable.
  • the spring element could be made of any fire protection material. A homogeneous layer structure and thus a uniform one However, it creates the protective effect of the fire protection element Of particular advantage if the spring element Gypsum fiber element or a calcium silicate element. A Gypsum fiber element or a calcium silicate element as a spring element is also particularly inexpensive.
  • the invention is at least one of the angle profiles in cross section L or U shaped.
  • the installation of the Profile is easier if the legs of the angle profile each have a different length. Is preferably the longer leg of the angle profile on one area facing the middle layer one of the outer Layers arranged, then the middle layer additionally stabilized.
  • a particularly effective edge protection of the outer plates is given if according to one another advantageous development of the invention the shorter Leg of the L-shaped angle profile or a die Leg connecting web of the U-shaped angle profile at least part of the edge area of one of the outer Layers.
  • a protrusion of connecting components from the fire protection element is advantageously avoided if at least one of the outer layers in the area of the screw connection or riveting a recess for receiving a Has screw or rivet head.
  • the fire protection element on two opposite Sides on cones, the cones being a common one Form swivel axis.
  • the fire protection element swivels in suitable storage locations to attach a wall or ceiling structure, so that it can be folded down around the pivot axis if necessary can and therefore a behind the wall or the ceiling Space, e.g. B. for maintenance work on supply lines in a building that is accessible.
  • Fig. 1 is a portion of a plate-shaped fire protection element 1 shown, the two outer, as plates formed layers 2, 3 and an intermediate, also designed as a medium plate Layer 4 has.
  • the plate-shaped layers 2-4 are sandwiched together and by means of a partially applied and non-combustible adhesive 11 connected with each other.
  • the outer layers 2, 3 are fire protection plates made of inorganic bound expanded glass granules, the beyond have sound-absorbing properties.
  • the middle layer 4 is formed and prevented by a gypsum fibreboard a passage of fire gases through the fire protection element 1. Due to the symmetrical layer structure of the fire protection element 1 will also be the case with large plates at bridging distances, e.g. B. in an order of magnitude of 2400 mm, may occur Deflection of the plates is largely prevented.
  • the angle section 5 has a shorter leg 17 and one longer leg 14, the shorter leg 17th an outer edge area of the top Layer 2 covers and the longer leg 14 on an inner, the area of the outer layer facing the middle layer 4 Layer 2 is arranged.
  • That enclosing an edge region of the layer 3 lying below U-shaped angle profile 6 encompasses this layer 3 in the way that a longer leg 15 on one of the middle Area 4 facing layer, a shorter leg 18 on a lower outer region and one of the legs 15, 18 connecting web 20 on an outer edge region the plate 3 is arranged.
  • the outer panels 2, 3 and the gypsum fibreboard in between 4 are connected by a screw 7.
  • the underlying plate 3 has a recess 8 in which a screw 9 is inserted.
  • the screw 9 braced - the legs 14, 15 of the angle profiles 5, 6 sweeping - the outer plates 2, 3 against each other, whereby the middle layer 4 is clamped in between; Consequently the plates 2 - 4 are non-positive and positive connected.
  • a screw head 24 is in the recess 8 sunk and from a closing the recess 8 Fire protection mass 10 covered. The screw head 24 is thus protected from direct flame in the event of fire.
  • FIG. 2 An embodiment of two arranged side by side Fire protection elements is shown in Fig. 2, where - how also in the other figures - each corresponding Components are provided with the same reference numerals.
  • a middle plate-shaped layer 4 has smaller ones here External dimensions as outer plate-shaped layers 2, 3 on and is a recess 23 forming opposite the outer Layers 2, 3 set back.
  • Recesses 23 of the adjacent fire protection elements is a spring element filling the recesses 13 inserted.
  • the spring element 13 does not create only mechanical support of the fire protection elements against each other, but also creates a continuous fire protection area without having to be covered or filled in separately Transition areas.
  • a bordering area of the upper outer layer 2 Angle profile 12 is U-shaped, with a longer leg 16 on one of the middle layer 4 facing Area of the plate 2 is arranged.
  • the thigh 16 thus also forms a wall of the recess 23 like a leg 15 of an edge area of the plate 3 enclosing angle profile 6.
  • Another wall of the recess 23 is formed by an outer edge of the plate 4.
  • a shorter leg 19 of the angle profile 12 is in the plate 2 sunk so that the leg 19 flush with closes the outer surface of the plate 2 and therefore no protruding or protruding interfering components are present on the plate 2.
  • One of the legs 16, 19 connecting web 21 faces the outer surface of the plate 2 towards a beveled area 22.
