Definitions

  • the invention relates to a fire-retardant closure device, in particular a fire-retardant gate, with at least one closing element for closing an opening in a closed position, wherein the closing element has at least one section having a rigid front surface and a rear surface facing away from the front surface, wherein between the front surface and the Rear surface intumescent material is arranged.
  • a fire-retardant door in the form of a plastic door, in which the closing element is formed by a roller-armor, is known.
  • the Rollpanzer consists of a plurality of Torlamellen, which have a rigid front surface made of a plastic and a rigid rear surface also made of a plastic. Fireproof material is arranged between the front surface and the rear surface. In case of fire burns or charred the fire-facing side, so for example, the front surface or the rear surface of the closing element.
  • a disadvantage of such a fire-retardant closure device is that it represents a fire load itself. When burning or charring the plastic is namely free heat, which is undesirable. It can also lead to smoke, which is also undesirable.
  • roller doors with a mineral wool or water filling.
  • the disadvantage of this is that such roller doors are quite thick, especially if they should have the classification "fire resistant" (T 90 or EI 90), and therefore poor or can not be wound because they require a considerable amount of space.
  • a generic closure device is from the DE 10 2005 023 426 B3 known.
  • the front surface and the rear surface are formed by metal sheets, each having hook profiles which engage with each other.
  • the sheet metal facing the fire warps.
  • the two metal sheets therefore move against each other by sliding in the hook connection to each other. This ensures that the metal sheet facing away from the fire does not deform and closes securely with the frame.
  • a disadvantage of this system is the complex production, which is the case in particular when the closing element has several sections. In this case, a separate hook connection must be made for each section. Another disadvantage is the low insulating effect.
  • a fire door is known in which laterally intumescent material is arranged to seal gaps to the door frame. Intumescent material is also used to seal other gaps, such as around the pusher. The fire resistance is ensured by calcium silicate material, which releases moisture in case of fire.
  • a disadvantage of such a fire door is their high weight, which makes a transfer of technology to closing elements that have more than one section, unattractive appearance.
  • EP 1 707 714 A2 is an emergency lock for a fire door known in which under the influence of temperature expanding material presses a bolt in a prepared receptacle for locking and thus locks the fire door.
  • Such technology is not applicable to the front surface and rear surface of the closure member.
  • the door leaf has a thin layer of foamable material.
  • the disadvantage of this is that such a layer can not be used for multi-sectional closing elements, since, for example, when the sections are rolled up, the layer is rubbed off.
  • a hoistway door is known in which the front surface is releasably secured to the rear surface.
  • the front surface facing the fire separates from the rear surface so that the front surface can curve.
  • the back surface remains unaffected.
  • roller door in which a plurality of pockets disposed under heat refrigerant dispensing substance.
  • a disadvantage of this roller door is the lack of mechanical stability.
  • the invention has for its object to produce a fire-retardant closure device that is particularly easy to manufacture.
  • the invention solves the problem by a generic fire-retardant closure device in which the front surface and the back surface are interconnected so that an increase in volume of the intumescent material leads to a displacement of the front surface relative to the back surface.
  • This closure device winds thin. Normally, if there is no fire, the intumescent material has a small volume and the front surface thus a small distance from the rear surface.
  • the closure device can be easily wound onto a shaft. The fact that the front surface and the back surface are connected together so that they can move against each other, the intumescent material can expand in case of fire. So a high fire retardant effect is achieved.
  • the rigid front surface and / or the rear surface can be made of metal, for example, so that it is particularly resistant to wear or are. It is also possible, unlike in the prior art, to use a material which retains its strength in the event of fire and does not burn or char. The use of metal also requires a high thermal conductivity, so that the intumescent material swells quickly and shields the fire heat.
  • the front surface and the rigid rear surface are made of combustible or other thermally unstable material. Also in this case, the fire load is reduced compared to existing closure devices, because the thermal instability of the front and rear surfaces unlike the prior art is not a constructive necessity. So it is possible to use fiber reinforced plastic for the front surface and / or the back surface.
  • the fire-retardant closure device is understood in particular to mean a device for closing openings, for example in buildings. It may, for example, be a door, a gate, a roller shutter or a conveyer closure.
  • the closing element could also be referred to as a partitioning element, since it is preferably designed to seal off the opening and to form a fire resistance.
  • the closure device is fire-retardant becomes understood that she withstands a fire for at least 30 minutes.
  • each closure device has a certain fire-spreading inhibitory effect, this is not meant in the present case.
  • Decisive is that the closure device is designed to inhibit the spread of fire and is designed to be particularly temperature resistant.
  • intumescent material is understood in particular any material that inflates when exposed to heat, without being flammable.
  • the intumescent material is designed so that it inflates in case of fire to twice its volume or more.
  • the closing element in particular that movable element of the closure device understood, which serves to close the opening.
  • the closing element in the case of a door, a swinging gate, a tilting gate or a swing gate is the door leaf, in the case of a roll-up door of the rolling armor and in the case of a sectional door the entirety of all sections.
  • the front surface is rigid, it is understood, in particular, that the front surface, which may for example be the front side of a door blade, does not substantially deform during operation.
  • the front surface and the back surface are not flexible as in a fire screen.
  • the fact that the front surface or the rear surface is rigid also relates in particular to the fire, so that in this case the volume increase of the intumescent material is made possible mainly by the displacement of the front surface relative to the rear surface and not by a deformation of the front and / or rear surface.
  • the closing element has a first section and at least one second section, which can be brought into a closed position to form a closing surface and which can be brought into a storage position for rolling up.
  • the first section and the second section are attached to each other, for example hinged together.
  • the fire retardant closure device is a roller shutter
  • the sections are formed by the door fins.
  • the sections corresponding to the profiles hinged together, which are also called rods.
  • there are more than two sections in particular there are a plurality of sections mounted in pairs.
  • the front surface and the rear surface are connected by means of a fire protection textile.
  • This fire-resistant textile is normally arranged, so if no fire, arranged in bows, placed meandering or folded.
  • the intumescent material expands and pushes the front surface and the back surface apart. This smoothes the fire-resistant textile and allows so that the front surface shifts relative to the back surface by both move away from each other. It is possible, but not necessary, for the move to be a guided move. So it is indeed possible that the front surface and the back surface are led to each other, but dispensable.
  • the front surface and the rear surface are incombustible.
  • they are made of metal or include metal and other non-combustible materials.
  • Metal has the advantage of being particularly wear-resistant.
  • Another advantage of using metal, such as a metal sheet, for the front surface and the back surface is that it is particularly easy to work on and finish, for example, to be painted.
  • the use of metal for the front surface and the back surface therefore leads to a particularly robust and low-wear closure device. This is particularly advantageous when it comes to the closure device is a gate, as this is often closed and opened in daily operation.
  • expansion joints which are formed so that they increase the volume of the intumescent Material allow the displacement of the front surface relative to the back surface.
  • the intumescent material expands, the intumescent material exerts a force on the front surface and the back surface. This force also acts on the expansion joints.
  • the expansion joints are designed to yield to the force so that the front surface can move relative to the back surface. This opens the expansion joints.
  • the expansion joints may be present in the front surface, the rear surface or in a separate component connecting the front surface and the rear surface.
  • the expansion joints have the advantage that the closing element is particularly easy to manufacture so that an increase in thickness is possible. Another advantage is that the expansion joints can be designed so that the closure device is sufficiently rigid and does not warp in normal operation. There is therefore no additional stiffening necessary.
  • the expansion joints are formed so that when moving the front surface relative to the rear surface, a heat transfer coefficient for a heat transfer from the front surface to the back surface decreases. It is assumed that the front surface facing the fire in case of fire, whereas the rear surface is facing away from the fire.
  • the heat transfer coefficient describes the amount of heat that flows in case of fire through the structure that has the expansion joints. For example, the heat transfer coefficient drops below half its original value.
  • the expansion joints are formed so that the intumescent material is retained between the front surface and the back surface.
  • the expansion joints are formed by slots in, for example, a metal sheet. These slots are so narrow that the intumescent material can not pass through.
  • the expansion joints can be cut or punched, for example.
  • the expansion joints can also be formed by a perforation, which ruptures in case of fire.
  • the expansion joints may be at least partially formed as predetermined breaking points. Because of their function, the expansion joints can also be referred to as target failure points. This is particularly advantageous when the intumescent material comprises or is a polyurethane foam.
  • the expansion joints are at least partially closed with a sealant.
  • the sealant is designed to seal the expansion joints against leakage of the intumescent material below a firing temperature and release the expansion joints above the firing temperature to permit displacement of the front surface relative to the back surface.
  • the sealant is a solder that is chosen so that it melts in the event of fire. Normally, that is, when there is no fire, the solder is fixed so that it fixes the front surface relative to the back surface.
  • the firing temperature at which the sealant loses its strength may be 100 ° C. But it is also possible to choose the sealant so that a loss of strength occurs only at 200 ° C or even higher temperature.
  • the front surface and the back surface of the first section are interconnected such that the volume increase of the intumescent material causes at least a portion of the intumescent material to enter an intermediate region between the first section and the second section in the event of fire.
  • the closure device is, for example, a roller door or sectional door
  • the individual sections ie Torlamellen, connected by hinge joints. Since the individual segments move towards each other during winding in the region of the joints, the sections in the region of the joints must be reduced in their material thickness. However, this reduced material thickness means a lower fire retardant effect in case of fire.
  • the closure device comprises a plurality of sections, wherein the respective front surface and rear surface are connected to each other so that intumescent material swells in the event of fire between the individual sections.
  • Such a roll or sectional door inhibits the spread of fire particularly effective in the event of fire and is at the same time easy to handle.
  • the fire retardant closure device is particularly easy to manufacture when the front surface and the rear surface are formed on a one-piece component.
  • the front surface and the rear surface may be formed on like-shaped components which are twisted together by 180 ° for making a section or a single door louver.
  • the closing element is designed as a slide plate, which has a recess for a conveyor, wherein expansion joints are arranged so that the volume increase of the intumescent material causes intumescent material to enter the recess in the event of fire.
  • a fire-retardant closure device is a conveyor termination, which is used in case of fire to close an opening in a building part through which a conveyor passes.
  • it may be a support chain conveyor or other conveyor.
  • the closure device is designed so that in case of fire, the slide sheet the Closing opening largely, wherein the recess prevents the slide blade touches down on the conveyor.
  • the swelling intumescent material enters a gap between the conveyor and the closing element and thus ensures a safe termination point.
  • the advantage of this is that the recess must only roughly correspond to the contour of the conveyor, since any remaining open areas are closed by the intumescent material.
  • the fire-retardant closure device comprises a fixed-field part, which is fixedly connected to the building part, in which the opening is formed, wherein the recess is arranged in the slide blade so that it surrounds the fixed-field part in case of fire.
