Definitions

  • the invention relates to a reinforcement, for a blanket or a carrier, with a fire protection formed by a plate cladding, wherein a reinforcing adhesive reinforcement is arranged on the underside of the ceiling or the carrier and at least covered on the underside by a plate clothing, the plate clothing at least one below the Adhesive reinforcement arranged plate layer comprises, which is constructed from at least one plate, and a method for producing a corresponding protected reinforcement.
  • the adhesives used in the known technical solutions of adhesive reinforcements have excellent strengths at normal room temperatures, but already from temperatures of about 45-50 ° C, the load capacity of the adhesive is very strong and the failure criterion is reached quickly.
  • the normally used epoxy resin adhesive can be used at temperatures above about 50 ° C, in any case above 60 ° C, in its function.
  • U1 Fire protection clothing which comprises insulation of insulation wool at least 10 mm thick and, beneath it, a covering of fire protection plaster of the fire class F120 with a thickness of more than 20 mm.
  • the object of the invention is therefore to provide a reinforcement with a formed by a plate cladding fire protection a method for their preparation, the or at yet reasonable manufacturing effort, only a slight increase in temperature even with prolonged exposure to fire in the adhesive reinforcement and thus maintaining the carrying capacity the carrier or the ceiling guaranteed.
  • a reinforcing adhesive reinforcement is arranged on the underside of the ceiling or the carrier and covered at least on the underside by a plate clothing, wherein the plate clothing is formed of material containing water of crystallization and at least one plate layer disposed below the adhesive reinforcement, which is composed of at least one plate, and further wherein between the adhesive reinforcement and the plate clothing or within the plate clothing to secure and maintain the carrying capacity of the bond of adhesive reinforcement and ceiling in case of fire, a diffusion-inhibiting or -blocking and / or reflective protective layer is arranged.
  • the protective layer is formed from a sheet-like film or as a lamination or application of a film on at least one plate.
  • a basic idea of the present invention was that, with a desired limitation of the temperature increase, excessive vapor diffusion poses a problem when using eg plates with water of crystallization.
  • the diffusion of hot steam may cause an additional and rapid increase in the temperature at the bond beyond the allowable height.
  • common materials do not sufficiently limit vapor diffusion and thus can not always prevent an increase in the temperature of the adhesive above the threshold temperature. This means that common design solutions without reducing vapor diffusion can not always provide fire safety and contain safety hazards.
  • gypsum boards are often used, which offer excellent in terms of their small thickness fire protection. This is due to the fact that the dihydrate (CaSO 4 ⁇ 2H 2 O) of the gypsum core contains about 20% of water of crystallization, which evaporates on exposure to fire and thereby consumes energy by conversion. A diffusion of the hot steam in the direction of the adhesive reinforcement and a consequent additional temperature increase of the adhesive reinforcement is effectively prevented or at least reduced by the protective layer according to the invention.
  • a reflection layer which may be formed together with the vapor diffusion-inhibiting layer or as a separate layer. When formed as a separate layer, both layers can lie directly against one another. However, it is also conceivable to provide the vapor diffusion-inhibiting protective layer and a reflective protective layer spatially separated. Also, in some applications it may be sufficient to provide only a vapor diffusion-inhibiting protective layer without special reflection property or only a reflective protective layer without vapor diffusion barrier.
  • the cooling effect of the water of crystallization can be used optimally with the solution according to the invention and, on the other hand, the water vapor which is hot above 100 ° C. can not cause a direct increase in temperature in the area of adhesive reinforcement.
  • a reduced transmission of heat can produce a protective layer which is also heat-reflecting.
  • a protective layer which, while not vapor-blocking but reflective, may also provide for reduced total heat transfer and thus good fire protection for the adhesive reinforcement for non-water-containing panels.
  • the lamination of a film on at least one plate allows an efficient attachment of the plate clothing, as for the attachment of the film no separate operation is required. It is advantageous if the film is laminated on all plates of a plate layer, as this results in an effective vapor barrier and / or heat reflection.
  • the formation of the protective layer on the other hand has the advantage that the selection of the plates is not limited to the laminated plates.
  • materials for the film metal, in particular aluminum, PVC or polyethylene have proven to be advantageous.
  • vapor barrier and / or reflective protective layer proposed here directly on the plates or on a separate support.
  • the protective layer is applied directly to the at least one plate, in particular by spraying, troweling or brushing. This allows a good fixation of the protective layer on the at least one plate.
  • the protective layer is preferably arranged or formed above or on the upper side of the at least one panel layer, namely the panel layer associated with the adhesive reinforcement. This has the advantage that the protective layer is not exposed to such high temperatures, as it is located on the top or inside of the fire protection clothing. This reduces the risk that the protective layer will be damaged.
  • the protective layer can also be designed with a slightly lower temperature resistance, which can result in a cost savings. If the protective layer is designed as a lamination of a film on at least one plate, the at least one plate of the plate layer or the uppermost plate layer is preferably rotated so that the laminated film is facing upwards.
  • the attachment of the protective layer on the upper or uppermost plate layer is particularly advantageous since, in this embodiment, crystal water can not diffuse from the plate to the adhesive reinforcement.
  • the protective layer is arranged so that direct contact between it and the adhesive reinforcement is avoided and a distance of preferably at least 1 mm to 2 mm remains. This results in an air cushion between the adhesive reinforcement and the protective layer, so that on the one hand further improves the thermal insulation and on the other hand, a thermal bridge is avoided.
  • the plate clothing comprises at least two plate layers arranged one above the other, the protective layer being arranged between the plate layers, for example between the two lowest or between the two uppermost plate layers.
  • the protective layer being arranged between the plate layers, for example between the two lowest or between the two uppermost plate layers.
  • the laminated plates of a plate layer can be arranged with their lamination facing an adjacent plate layer.
  • the above-described embodiment of providing the protective layer between the plate layers may be considered primarily for a protective layer in which the reflective function is in the foreground. Specifically, this may be the case in applications in which the plate clothing is made from plates without embedded crystal water.
  • lateral cover elements are arranged so that even the side of the adhesive reinforcement is a good thermal insulation.
  • the plate clothing to cover the adhesive reinforcement by lateral plates on both or all sides of the Klebebeehrung, in particular so that the plate clothing comprises the adhesive reinforcement completely or almost completely.
  • the protective layer is on or through the plate clothing, wrapping the adhesive reinforcement, each edge led to the carrier or to the ceiling.
  • This embodiment has the advantage that the reinforcement is air-tight and vapor-tight or at least largely closed air- and vapor-tight from the environment, resulting in a particularly good thermal insulation, but especially a particularly low vapor diffusion or a particularly good vapor barrier.
  • the protective layer formed as a film is in one piece.
  • one-piece design of the protective layer results in a particularly effective vapor barrier, since there are no shocks or gaps between the sections of the protective layer, which could make the vapor barrier partially permeable.
  • the protective layer may also include multiple sections with intermediate joints or butt joints.
  • the joints of the protective layer are protected by fire protection, in particular by providing bent parallel end portions of the adjacent portions of the protective layer and / or by providing a separate cover strip.
  • the foils or the laminated panels are joined together and / or glued as far as possible to form a protective layer which is as closed as possible. Bonding is preferably carried out so that all shocks are completely or almost completely sealed. The bond improves the vapor-tightness of the fire protection clothing.
  • further plate layers can be arranged depending on the thickness of the fire protection target.
  • the butt joints with a cover strip preferably from about 50 mm wide diffusion-inhibiting adhesive tape, for example, aluminum adhesive tape, especially on the back of the plate, taped.
  • Aluminum tape can be applied easily and quickly and also has good properties in terms of the desired heat reflection or the desired vapor-tightness.
  • the protective layer is temperature resistant up to at least 100 ° C and / or has a high vapor diffusion resistance and / or is reflective, especially heat-reflecting.
  • the heat reflection also reduces the heat transfer of the fire protection clothing and can therefore also increase the fire resistance of the adhesive reinforcement.
  • the film is formed with a water vapor diffusion equivalent air layer thickness greater than 20 m, preferably greater than 100 m, more preferably greater than 1000 m.
  • a high water vapor diffusion equivalent air layer thickness results in an effective barrier to steam.
  • the film is preferably in the form of a multilayer film, for example of polyethylene-coated and aluminum-coated kraft paper or single-layer films, for example of metal, in particular aluminum, PVC or polyethylene (PE).
  • Multilayer films or composite films can be laminated particularly well. Films of aluminum or polyethylene and aluminum coated kraft paper reflect some of the heat radiation. In addition, this type of film is vapor-tight or largely vapor-tight. The combination of kraft paper and aluminum in different thicknesses increases the mechanical stability of the film.
  • the multilayer or composite film comprises a kraft paper layer, in particular with a basis weight of 50 g / g 2 , a polyethylene layer, in particular with a weight per unit area of 30 g / m 2 and a preferably 9 ⁇ m thick aluminum foil with a water vapor diffusion equivalent air layer thickness s d greater than 1000 m. It has been found that this composition in the multilayer or composite film has particularly good technological properties in terms of plate coating, mechanical stability and vapor diffusion.
  • the underside of the lowermost plate layer has a smooth and / or scratch-resistant, in particular visibly executed or executable surface.
  • no additional layer for example, no plaster layer or plate layer, is required, which reduces the installation times for the Klebebestehrung.
  • the installation costs can also be reduced as a result, since no additional material is required for the cover layer. Since, in particular, the application of an additional layer of plaster is not absolutely necessary, the accumulation of dirt is also reduced.
  • To attach the plate clothing all technically common mounting options are considered, in particular screwing, clamping, pegging, each with or without substructure.
  • the panel clothing is made of calcium silicate panels, cementitious mineral panels, vermiculite-based panels, but preferably of water-containing material, e.g. Gypsum in the form of glass-fiber-reinforced, glass-fiber-nonwoven or paper-fiber-reinforced plasterboard or plasterboard or formed from a combination of these plates.
  • the panel apparel or fire protective garment converts a fire resistance time of F90, the panel garment having a total thickness of max. 40 - 50 mm.
  • a small total thickness of the plate clothing is of great importance, since an adhesive reinforcement often takes place in old buildings with a comparatively low ceiling height. Due to a low overall height of the adhesive reinforcement including the panel cladding, the required or desired ceiling height can be made possible while at the same time compliance with the fire protection requirements, or at least made easier.
  • the object of protective layer and plate clothing is to keep the temperature increase as long as possible before the carrier or the ceiling.
  • a low thermal conductivity is advantageous for the plate clothing.
  • the ceiling or the support comprises a reinforced concrete surface, wherein a cavity is formed between clothing and reinforced concrete surface, the thickness of carbon fibers for technical reasons is preferably at least about 6 mm.
  • At least one plate layer is already coated with a film prior to installation in the plate clothing, since this can reduce the installation effort and thus the installation costs.
