Definitions

  • the invention relates to a method for producing a fire-retardant casing for metal and wood profiles, in which in a first step a fire-retardant covering, for example a plate, is attached to a processing base by gluing.
  • a fire-retardant covering for example a plate
  • a method mentioned at the outset has become known, for example, with the subject of DE-GM 7 5o7 543.
  • the processing base consists of a completely bent, box-shaped profile, on the inside of which the fire-retardant covering is glued in the form of plates.
  • a disadvantage of the known method is that the processing base (box-shaped metal profile) must first be bent in order to then glue in the fire-retardant covering. It is therefore no longer possible to adapt the box-shaped profile differently to encased beams.
  • This fire-retardant casing is intended to ensure that the support does not warp in the event of a fire.
  • the disadvantage of this design is that the production of the casing on the building is expensive because it is time-consuming and the fire resistance at the parting lines is not always guaranteed because it is exposed to fire on lightest burst, that is, this is the weakest point. This bursting is due to the fact that the glue joint is relatively small in these known designs. Undercuts are generally not provided for manufacturing reasons. The fire resistance of this casing is therefore relatively low.
  • the object of the invention is to remedy this situation and to provide the sheathing in such a way that prefabrication in the factory is possible in accordance with the various standardized profile beams.
  • the actual assembly on site is then very short.
  • a much greater fire resistance is also achieved, that is, higher degrees of heat are prevented from the component to be sheathed.
  • a fire-retardant covering e.g. a plate on a processing base
  • a film ensures that the plate can now be machined economically on machines, e.g. by milling notches, undercuts can also be milled, and this is a continuous process, which means that these jackets can be used for very tall developers and also for Real estate developers are processed in the same way, so that a much lower inventory is now necessary. You can bring these notches or the like at such a distance from each other that the processing of known standard bearers is recorded.
  • the processing base can serve to ensure that the other side of this processing base can be designed both as a plaster base and as a decorative pattern. For example, it does not have to be fire-retardant if beams are clad in bungalows where fire-retardancy is not prescribed or is not desired.
  • this processing base which is a film, can also be fire-retardant; it can be designed as decorative cladding, and it can be provided that mosaic stones can also be applied in a manner known per se.
  • the component is clad in that glue is introduced into the parting lines, relatively large glue lines being possible which have a much greater security against bursting open when exposed to fire.
  • the jackets produced by this method can be designed in different ways.
  • the processing base on the outside can be designed as a plaster base, it can also be designed as a decorative pattern on the outside.
  • it can also be fire-retardant or it can also be made of normal materials as decorative cladding composed.
  • the parting lines can have undercuts, e.g. in a step-like shape to increase the durability of the connection. Additional parts can also be inserted into these joints, which then form a unitary whole with the sheathing by gluing.
  • the processing base can have protruding tabs that serve to engage a tensioning strap when the casing is tensioned.
  • top and bottom of such a casing has undercuts, notches or the like, so that another casing can also be placed in the length of the casing and these parting lines are also fire-retardant.
  • Undercuts and overlaps can also be provided, tongue and groove connections are also possible.
  • processing base is removed after the developer has been applied or encased, this processing base then being provided with a pressure sensitive adhesive.
  • a pressure sensitive adhesive e.g. as a mortar bed, and place decorative stones, mica parts or similar in this mortar bed, which then give the wearer the impression of a stone column, if the film is now removed, these stone particles become visible .
  • the processing film also protrudes on the upper and lower end faces in such a way that a parting line is covered. Undercuts can also be provided there.
  • the casing is an application of the invention to understand carriers, but also the manufacture of construction elements, for example in furniture construction. It is always important that the processing base is not used to attach the parts to be machined, but the processing base is used to arrange the parts forming the finished part next to each other so that only parting lines have to be made and then the processing base is used in order to produce the structural part, that is, it then serves as a casing or as a fixation of the structural parts to one another, which may later be glued, riveted or grouted. It is known that parts are placed on processing documents which are processed but which are then removed from this processing document in order to be used separately. However, using the processing document to simultaneously manufacture the construction part is part of the invention.
  • a fire-retardant covering produced according to the method is characterized in that the covering consists of two plate elements made of rock wool, glass wool or basalt wool, the plate elements being separated by a reflective film in the area of their horizontal contact surface, and the reflective film on both sides with a highly heat-resistant glue layer the associated plate element is connected.
  • the mineral wool board elements on their own do not have good fire resistance.
  • the reflection film consists of, for example, an aluminum film or another metal film, but it can also consist of a silver-damped plastic film or the like. It is only important that this aluminum foil withstands temperatures up to approximately 1000 ° without substance destruction.
  • the reflective tape serves here as a reflective screen, i.e. it reflects a large part of the radiated heat.
  • the reflective tape acts as a vapor barrier, i.e. hot air or moist air cannot pass through the covering, this also protects the inside.
  • the basic substance is a powder which is mixed with water and which, when ready for use, has a slightly yellowish, glass-like, transparent appearance.
  • This glue is then applied and dried and results in a very hard and brittle connection layer after drying.
  • this glue layer acts as a protective screen for the reflective film and this glue layer protects the reflective film from heat decomposition.
  • this water glass glue has approximately the same expansion capacity and similar brittleness behavior as the reflective film, so that both materials complement each other. This protects the reflective tape from warping, and the glue layer forms a protective screen that surrounds the reflective sheet on both sides (all sides).
  • the glue layer penetrates into the fibrous substance of the plate elements at the connecting layer, and holds the plate elements with high strength connected to the glue layer and the reflective film.
  • fire-retardant coverings of any thickness can be built up.
  • the inner plate element can e.g. be constructed thinner than the outer plate element. Therefore, all requirements for thermal insulation can be taken into account.
  • the processing document 1 can be seen in FIG. 1. It extends beyond the fire-retardant covering 3 by the width 2.
  • the fire-retardant covering or any covering 3 is applied to this processing base.
  • notches 4 are present. These notches 4, which are located in area B in the exemplary embodiment according to FIG. 1, are delimited by area C. These areas B and C are designed so that when the casing is placed around the profile to be protected, parting lines are formed which are then filled with glue or also with fire-retardant materials.
  • area B is triangular in cross section, while area C is straight.
  • the processing film 1 can be designed as a part that can be used repeatedly, that is, it can be removed after the sheathing in order to be used again.
  • the connection with the covering 3 would be given by a pressure sensitive adhesive.
  • it can also be used as a component by being decorative, or else e.g. on its outer side e.g. is provided with a cover film which is peeled off after the covering, in order then either to have a decorative effect or, if a pressure-sensitive adhesive was present, to permit the application of mosaic or similar decorative parts.
  • step-shaped undercuts 5 which, in the case of a corner connection shown there, extend in a labyrinth-like manner inward from a heat acting from the outside in the direction of the arrow 6 and thus keep the component 7 to be protected free from the effects of temperature.
  • connection is also more durable than just a mitred corner connection.
  • connection 8 shows a step-shaped connection 8 in area C, while in area B a further connection option 9 is shown, which is also suitable for covering corners.
  • 5 shows a possibility of increasing the height of a sheathing, that is to say that the covering 3 should continue in an extension of the covering 3 ', as well as the processing base in a further area as the base 1'.
  • a tongue and groove connection 10 is used here, material (e.g. pressed mineral wool) which is fire-retardant being used for the spring.
  • the connection area is overlapped, as shown in FIG. 5.
  • FIG. 6, like FIG. 5, shows another possibility in which the vertical butt joint is formed by tongue and groove, that is to say that, in contrast to FIG. 5, where the butt joint is formed by tongue and groove, galvanizing corresponds. In both cases there is an overlap, which is particularly evident from the position of the dividing line 11 in relation to the covering pieces 3 and 3 '.
  • Fig. 7 shows schematically a possible design of the casing.
  • a wide flange beam 12 is covered at the top and bottom with wooden strips 13.
  • irregularly designed components to be protected can also be assigned a shape that can be easily encased, that is, has favorable geometric dimensions, such as squares, rectangles or round cross sections.
  • the previously on the processing document 1 applied plates or the covering 3 with a training in the areas B, as indicated, for example, in FIG. 3, are thus placed around the profile, the corner connections 5 being connected to one another by adhesive or other means.
  • the processing base 1 can be a plastic fabric, which serves as a plaster base. It can also be deleted later.
  • the processing base itself can also be designed as a fire-retardant covering, e.g. asbestos with a decorative pattern. Furthermore, films of all kinds with decorative covering protection can also be used.
  • a stone mosaic covering 17 can then later be applied to this processing base. Of course, it is also possible to first apply the stone mosaic covering to a stretcher or peel-off film 18, that is to say to lay it out in terms of area, this stone mosaic covering being connected to the processing documents 1 and the two method steps then being as described in the previous figures.
  • the clamping pressure generated in this way ensures that the entire casing, with the glues and connecting elements introduced, covers the metal profile to be protected practically without air pockets. After the connection means such as glue or the like have set, the tensioning belt and tensioning device are then removed.
  • Fig. 9 shows in the basic concept the processing for the sheathing of a round column.
  • the notches or cutouts 4 are then designed differently, that is to say the angles 22 are designed in accordance with the shape to be encased.
  • the application of the invention is not only to be understood as the sheathing of beams, but also, as stated at the outset, the manufacture of structural elements, e.g. in furniture construction.
  • the refractory casing shown in FIG. 11 consists of the same parts as the refractory casing according to FIG. 7.
  • the fire-resistant covering consists of a two-layer composite covering, namely an inner fire-resistant covering. which is glued to the outer fire-retardant covering 25 via a reflection film and interposed inner and outer glue layers 23.
  • the surface of the outer fire-retardant covering adjoining the processing base 1 is of course glued to this processing base by a further layer of glue 23.
  • the reflective film 24 extends as a protective layer (protective screen) through all abutting sheathing g -elements, so that this forms an all-round, completely enveloping reflective screen.
  • the fire-retardant composite covering consisting of the inner 3 and the outer covering 25, can also be screwed together.
