Definitions

  • the invention relates to a multi-chamber hollow profile according to the preamble of claim 1, a fire protection structure, in particular a frame for fire-resistant glazing, in which this multi-chamber hollow profile is inserted, a method for producing the multi-chamber hollow profile, and a use of the multi-chamber hollow profile.
  • fire-resistant frames such as glazing frames
  • the supporting frame profile and the hollow profile each have cavities which typically extend in the longitudinal direction of the frame profile. These cavities can have different functions. For example, they can be filled with a fire protection material.
  • the firestop material is typically introduced into at least one cavity as a preformed building block, such as a rigid insert or insert. Other cavities that are present can be used, for example, as cable ducts or to accommodate fittings or the like.
  • the following description refers to load-bearing fire-resistant frames for fire protection elements, such as frames for fire protection glazing, when frames, fire protection frames, glazing frames, frame profiles or frame profile parts are mentioned.
  • the invention also relates generally to multi-chamber hollow sections for incorporation into fire protection structures such as fire protection windows, doors or walls.
  • a standard construction of a load-bearing frame section comprises two frame sections and bolts which firmly connect the two frame sections together in the finished frame. If a hollow profile filled with a fire protection material is to be used in such a construction made of two frame profile parts and connecting bolts, passage bores for the passage of the bolts are usually produced in the hollow profile filled with fire protection material.
  • EP 1 681 430 A2 discloses a composite profile, for example for a window frame, which comprises two metal profile parts mounted at a fixed distance from one another and connected to one another by bolts arranged perpendicular to the metal profile parts.
  • a fire-resistant and/or heat-resistant insulating material made of alum or glass wool is arranged between the metal profile parts.
  • the insulation material is protected from environmental influences by an enclosing jacket and side covers.
  • a further external cavity is formed between the jacket and the cover, which can serve, for example, as a cable duct or cavity for additional fire protection material.
  • the bolts pass through the insulation material and require holes to be drilled in the jacket.
  • the load-bearing frame profile has a central profile made of fiber-reinforced plastic, on the opposite sides of which metal support profiles are attached.
  • Inner longitudinal chambers are provided within the profile made of fiber-reinforced plastic, in which fittings and/or corner connection angles and/or insert parts made of calcium silicate can be inserted.
  • DE10144551A1 discloses a fire protection element for constructing a framework on a building for holding a clampable component, such as fire protection glazing.
  • a core profile serving as an anchor is surrounded by a heat-insulating filling compound, which is surrounded by a casing.
  • the hollow chamber contained in some embodiments in the core profile does not extend to the outer surfaces of the casing enclosing the fire protection material in the form of a load-bearing box profile, but is always surrounded on all sides by the filling compound.
  • the hollow chamber is not intended to hold any object.
  • WO 2003/023175 A1 discloses a frame profile with fire protection material filling.
  • a hollow chamber for accommodating a locking bar of a locking mechanism or the like can be provided in the fire protection material filling ( 3 ).
  • the fire protection material is filled directly into the frame and is therefore not an insert or a separate filling profile with its own jacket profile and fire protection material filling.
  • the composite profile according to EP 1 681 430 A2 has several disadvantages. Holes must be provided in the jacket for the passage of the bolts. In one embodiment, cutouts are produced directly in the insulating material, in which the cover is fastened, so that the insulating material acting as a fire protection material is not hermetically sealed at several points. The drilled holes and recesses can become brittle over time leakage of insulation material. Moving parts in the bores can cause mechanical abrasion of the unprotected insulation material. In the event of a fire, cooling water that is bound in a coolant in the insulation material can escape prematurely through the holes or recesses. This is disadvantageous for the cooling capacity of the insulation material. Finally, the hollow chamber formed between the jacket and the cover for accommodating cables is located in the composite profile according to FIG EP 1 681 430 A2 completely outside the insulation material, so that in the event of a fire, the cables are only insufficiently protected from the fire.
  • the longitudinal chambers are provided in the supporting central frame profile.
  • the fixed connection between the longitudinal chambers and the load-bearing profile has the disadvantage, among other things, that the type, size and arrangement of the chambers for the finished fire protection frame are completely defined. This system thus lacks the desired flexibility.
  • the invention is based on the object of specifying a multi-chamber hollow profile in which fire protection material is better protected if cavities for accommodating mechanical connecting devices, fittings, cables or the like are provided in the fire protection material.
  • the object of the present invention is also at least one hollow chamber of the multi-chamber hollow profile, which serves as a shaft for heat-sensitive components such as optical or electrical cables, electronic components such as sensors, rods, screws, connecting bolts, fittings, reinforcement inserts (e.g. burglar-resistant inserts made of polycarbonate) or the like To better protect against the heat of a fire by at least one fire protection material chamber.
  • the invention is based on the object of specifying a multi-chamber hollow profile in which at least one hollow chamber for accommodating cables, sensors, connecting bolts, fittings, reinforcing inserts or the like (hereinafter: “hollow accommodating chamber”), and at least one hollow chamber filled with fire protection material ( hereinafter referred to as “fire protection material chamber”) can be combined with one another as flexibly and as required.
  • high accommodating chamber for accommodating cables, sensors, connecting bolts, fittings, reinforcing inserts or the like
  • fire protection material chamber at least one hollow chamber filled with fire protection material
  • the wall of the hollow receiving chamber is intended in particular to prevent particles of the fire protection material from a fire protection material chamber from penetrating into the hollow receiving chamber, and in a preferred embodiment also the ingress of liquids such as water, in particular also in the form of steam, from the fire protection material.
  • the primary function of the wall of the receiving hollow chamber is therefore to permanently at least largely exclude the penetration of fire protection material from a fire protection material chamber into the receiving hollow chamber during the production of the multi-chamber hollow profile, during its handling and after its intended installation in a fire protection structure under normal conditions, see above that - apart from the case of fire - at most insignificant amounts of the fire protection material can get into the receiving cavity.
  • plastics both thermosets and thermoplastics
  • plastics preferably from the substance groups of polyamides, polyimides, polyetherimides, polybenzimidazoles, polyaryletherketones, polyetheretherketones (PEEK), silicones, fluoropolymers, silicone resins, acrylonitrile -Butadiene-styrene (ABS), styrene-acrylonitrile (SAN), acrylester-styrene-acrylonitrile (ASA), PTFE, synthetic resins, phenoplasts, polycarbonates, polyacrylates, rubbers, in particular ethylene-propylene-diene rubber, polylactates, PMMA, PET , PVC, TPU, polyethylene, polypropylene, polystyrene; also fiber-reinforced plastics, in particular glass-fiber and/or carbon-reinforced plastics (GRP, CFRP), preferably based on epoxy resins, melamine
  • the multi-chamber hollow profile according to the invention comprises several hollow chambers. At least one of these hollow chambers is filled with fire protection material and thus forms at least one fire protection material chamber. Fire protection material chambers can be partially filled with fire protection material, e.g. B. only on the inside of their chamber walls or by inserting an undersized insert, or they can be substantially completely filled with fire protection material.
  • the multi-chamber hollow profile according to the invention comprises at least one hollow chamber designed to accommodate components such as optical or electrical cables, electronic components such as sensors, rods, screws, bolts, reinforcing inserts or the like.
  • the multi-chamber hollow profile can optionally have at least one further hollow chamber that is neither filled with fire protection material nor intended to accommodate components such as sensors, fittings, cables, bolts, reinforcement inserts or the like (hereinafter "empty chambers").
  • the receiving hollow chambers, fire protection material chambers or empty chambers can have an elongated or a flat shape, for example.
  • the chambers for glazing frames are elongated chambers with significantly larger longitudinal than transverse dimensions.
  • the chambers of the typical glazing frame design are elongate, they have one or more longitudinal walls and at the ends thereof one or more faces or end walls.
  • the longitudinal walls in this case run parallel to the longitudinal axis of the chambers and the glazing frame, and the end walls or end faces are arranged transversely or obliquely to this longitudinal axis.
  • the multi-chamber hollow profile is to be introduced into flat fire protection structures such as fire protection doors or fire walls
  • the multi-chamber hollow profile is also usually flat with a relatively small thickness compared to the external dimensions (length/width).
  • one or more of the chambers can also have a flat extension.
  • the walls of the receiving hollow chamber(s) run essentially parallel to the longitudinal walls of the fire protection material chamber(s).
  • receiving hollow chambers are provided, for example for receiving bolts for connecting the separate profile parts of a glazing frame
  • the walls of the receiving hollow chambers are arranged essentially perpendicular to the longitudinal axis of the multi-chamber hollow profile and thus essentially perpendicular to the longitudinal walls of the fire protection material chamber(s).
  • the main axis of the receiving hollow chamber(s) runs perpendicularly to the main axis of the fire protection material chamber(s).
  • the end faces of the receiving hollow chamber(s) are rotated 90 degrees relative to the end faces or end walls of the fire protection material chamber(s) and at least one of them, preferably both end faces, are arranged in the area of the outer wall of the multi-chamber hollow profile running along the profile.
  • the invention is used for both orientations of receiving hollow chambers, namely essentially parallel or perpendicular to the fire protection material chambers, as well as intermediate forms.
  • the at least one receiving hollow chamber preferably passes through the multi-chamber hollow profile from an area of its outer wall or an end face to an opposite area of its outer wall or an end face, so that a component can be pushed through the receiving hollow chamber of the multi-chamber hollow profile or into it from two sides or can be drawn.
  • a receiving hollow chamber is designed in the manner of a blind hole and is only accessible from an outer wall or end face of the multi-chamber hollow profile. This can be useful if small, heat-sensitive components that require little space are to be accommodated in the receiving hollow chamber or if bolts or other mechanical fixing means only penetrate into the multi-chamber hollow profile for fixing and are not intended to penetrate it completely.
  • the fire protection material chambers are closed at their end faces located in the area of the outer wall or an end face of the multi-chamber hollow profile, for example with openable and closable covers. This is advantageous in order to maximize the cooling effect in the event of a fire. However, they can also be open at their ends.
  • one or more seals or other indentations or cross-sectional constrictions that reduce the flow cross-section are present in a hollow receiving chamber.
  • the inner surface of the wall of a receiving cavity can be provided with a three-dimensional structure such as grooves, ribs or a grain, generally expressed with a relief-like structure or a structure with macroscopic unevenness. This is particularly advantageous when hollow receiving chambers run vertically in the installation situation, since this increases the flow through the hollow receiving chambers optimized with hot gases (chimney effect), in particular can be throttled.
  • fire protection material chambers are open on at least one of their end faces.
  • fire protection material chambers are preferably completely encased with a wall.
  • the main advantage of completely encasing the fire protection material in the fire protection material chambers, including their front sides, is that there is then no exchange of substances between the interior of these chambers and their surroundings.
  • a large number of materials are basically suitable, which separate the fire protection material in a fire protection material chamber from other hollow chambers of the multi-chamber hollow profile, including in particular the materials listed above that are suitable for the wall the at least one receiving cavity are suitable.
  • the outer wall of the multi-chamber hollow profile has the function of mechanically protecting and stabilizing the at least one fire protection material chamber and the at least one receiving hollow chamber and protecting it against harmful influences from the outside, preferably for as long as possible after the start of a fire.
  • the outer wall can be part of the wall of at least one fire protection material chamber, it can also form a small part of the wall of at least one receiving hollow chamber.
  • the requirements formulated for the walls in question also apply as minimum requirements where these hollow chamber walls are part of the outer wall of the multi-chamber hollow profile.
  • the outer wall of the multi-chamber hollow profile is preferably essentially impermeable to fire protection material, in particular in its hardened state, and to its components thanks to a suitable choice of material and thickness, and this preferably remains up to a temperature of the outer wall of at least 70° C., in particular up to at least 100 °C
  • the full cooling capacity of the fire protection material is only provided in the event of a fire.
  • an outer wall material that is impermeable to the encased fire protection material e.g organic polymers, in particular plastics (mainly GRP or CRP), cardboard, or metals
  • an outer wall material that is impermeable to the encased fire protection material e.g organic polymers, in particular plastics (mainly GRP or CRP), cardboard, or metals
  • no harmful foreign substances can get into the multi-chamber hollow profile and in particular into its fire protection material chamber(s) from the outside.
  • their encasing by the outer wall must be essentially complete.
  • the outer wall, which is impermeable to fire protection material should therefore also be free of larger pores.
  • less thermally stable materials can also be used for the walls of hollow receiving chambers, which can also be permeable to components of the fire protection material or the foamed fire protection material.
  • a porous, mesh-like or net-like material is used for the wall of a receiving hollow chamber, components of the fire protection material, such as water vapor in particular, can penetrate the wall in the event of a fire.
  • sufficiently small pores a small size of the mesh and/or small net spacing, at least mechanical protection can be guaranteed, since particles of the hardened fire protection material can neither escape from a fire protection material chamber surrounding the hollow receiving chamber nor can solid objects penetrate into it. This is of particular advantage in the case of receiving hollow chambers running transversely to fire protection material chambers, which are intended, for example, for receiving bolts.
  • gaseous decomposition products occurring in the fire protection material can escape through the porous wall of a hollow receiving chamber and from there into the environment in a controlled manner.
  • coolants preferably steam
  • from the fire protection material from at least one fire protection material chamber surrounding the hollow receiving chamber can cool, for example, metal connecting bolts of the fire protection frame located in the hollow receiving space, into which the multi-chamber hollow profile is inserted, and thereby improve the fire resistance of the frame.
  • Another significant advantage of the multi-chamber hollow profile according to the invention is that receiving hollow chambers, which are used as cable ducts, are completely or predominantly surrounded by fire protection material in the area of their walls.
  • the cables are particularly well protected against the effects of the heat of a fire.
  • Cables or other components introduced into the receiving hollow chamber can be poured, foamed or fixed there with additional material, in particular fire protection material.
  • the material used advantageously has cooling and/or insulating properties.
  • a further advantage of the multi-chamber hollow profile is its modular structure, since the hollow chambers to be used as hollow receiving chambers and fire protection material chambers can be selected application-specifically and thus different variants of the multi-chamber hollow profile can be provided as required. All hollow chambers can first be joined together with empty cavities to form a multi-chamber hollow profile, and some of these are then filled with fire protection material, whereby fire protection material chambers are created from the filled hollow chambers, while the remaining unfilled hollow chambers are available as receiving hollow chambers or empty chambers. However, fire protection material chambers can also be produced in advance and then combined with at least one receiving hollow chamber.
  • Simple designs such as cylinders or cuboid profiles, can be put together particularly flexibly and adapted to different fire protection structures such as frames. Furthermore, it is advantageously possible to produce a one-piece hollow chamber system (with hollow chambers in the longitudinal direction, but in particular with receiving hollow chambers oriented transversely thereto for the passage of bolts) by polymer processing methods and then to fill individual hollow chambers with fire protection material in the one-piece multi-chamber hollow profile and one of the hollow chambers provide as a receiving cavity.
  • This modular design makes it possible to set different fire protection classes in a targeted manner by varying the proportion of fire protection material and the arrangement of the fire protection material.
  • receiving hollow chambers can remain open on one or both sides for receiving components such as cables, or can be opened and then, if necessary, closed with adapted covers.
  • Fire protection material chambers are open on their front sides for filling or can be opened and are then either closed with covers in the filled state / after the fire protection material has hardened in situ or remain so permanently open.
  • covers are not always required, particularly if the hollow receiving chambers are used for inserting or passing through bolts.
  • the walls of the receiving hollow chamber(s) and the fire protection material chamber(s) extend parallel to the main axis of the multi-chamber hollow profile, and the end faces of the receiving hollow chamber(s) run essentially parallel to the end faces of the fire protection material chamber(s).
  • This configuration corresponds to the essential basic arrangement according to the invention, in which the at least one receiving hollow chamber and the at least one fire protection material chamber run parallel to the main axis of the multi-chamber hollow profile and to the main axis of the fire protection frame into which the hollow profile is inserted.
  • the at least one receiving hollow chamber is preferably open at both of its end faces, so that cables can be pulled through which are protected by surrounding fire protection material within the receiving hollow chamber with its wall being interposed.

  • This configuration is suitable for a situation in which a multi-chamber hollow profile must have at least one passage transversely to the longitudinal axis in order, for example, to be able to provide at least one connecting bolt between two frame profile parts, between which the multi-chamber hollow profile according to the invention is arranged, or at least one fixing bolt which is attached to a Frame part is attached to be able to introduce at least one receiving cavity designed as a blind hole.
  • the multi-chamber hollow profile is preferably produced in one or more parts by a polymer processing method such as injection molding, and because of the increased complexity of the inner contour of the cavity of the fire protection material chamber(s), it is preferably filled with liquid precursors of fire protection materials, which harden in situ in the at least one fire protection material chamber .

The outer wall is located on the periphery of the multi-chamber hollow profile and delimits it from the environment, while inner walls are arranged inside the profile.
  • Walls between adjacent fire protection material chambers and walls between adjacent receiving hollow chambers and walls between fire protection material chambers and receiving hollow chambers can either be formed by common walls, especially if the multi-chamber hollow profile was produced in one piece by injection molding, or two or more walls can adjoin one another here if the individual hollow chambers are produced separately from one another and then joined together to form a multi-chamber hollow profile.

The modern technology available is the production of particularly complex components using 3D printers.
  • receiving hollow chambers running transversely to the longitudinal extent of a multi-chamber hollow profile for accommodating cables or fastening elements such as bolts or screws can also be made before the fire protection material is filled into the fire protection material chamber(s) by inserting pipe sections with walls that are impermeable to the fire protection material (the can also be designed porous, net-like or mesh-like) in suitable bores or openings in opposite areas of the outer wall and, if necessary, in inner walls within the multi-chamber hollow profile.
