Definitions

  • the invention relates to a fire protection fastening device for fastening a door operator. Furthermore, the invention shows arrangements comprising a door operator together with a fire protection fastening device.
  • Door operators are used to close and/or open doors.
  • door closers and door drives are referred to as door actuators.
  • a spring accumulator is usually charged by the manual opening movement. The energy stored in this way is used to close the door.
  • the door drive for example, the door can be opened and/or closed independently by means of electromechanics or hydraulics.
  • Door operators are usually attached to a mounting surface, ie on the door leaf or the frame or the wall.
  • a mounting surface ie on the door leaf or the frame or the wall.
  • flammable fluids such as hydraulic oils
  • Appropriate measures should be taken to prevent the fluid in the door actuator from heating up too much in the event of a fire and potentially igniting it.
  • the invention describes a fire protection fastening device for fastening a door operator.
  • the door operator is a door closer or a door drive.
  • the door operator must be attached to a mounting surface. This mounting surface is formed in particular by a door, frame or wall.
  • the fire protection fastening device includes a frame.
  • the frame is designed to be arranged between the door operator and the mounting surface. If there is no separate mounting plate, the door operator lies directly on the front of the frame. The back of the frame faces the mounting surface; is particularly close to the mounting surface.
  • a mounting plate can be used between the frame of the fire protection attachment and the door operator. In particular, the mounting plate is screwed to the frame of the fire protection fastening device and the door operator is fastened to the mounting plate.
  • the frame of the fire protection fastening device is an integral part of the door operator. This configuration will also be explained in detail.
  • a mounting axis is defined to describe the invention.
  • the mounting axis is perpendicular to the frame, particularly perpendicular to the back of the frame. Furthermore, the mounting axis is perpendicular to the mounting surface. For example, the mounting axis is parallel to the screws used to bolt the frame to the mounting surface. According to an alternative definition, the mounting axis is perpendicular to the output axis of the door operator.
  • the door operator can be connected to the door or wall via this output shaft, for example via a linkage.
  • At least one reaction chamber is formed in the frame of the fire protection fastening device.
  • the frame has several reaction chambers.
  • two, three, four, five, six, seven or eight reaction chambers are provided in the frame.
  • the invention is usually described using a reaction chamber, it always being provided that the several reaction chambers are of identical design.
  • the reaction chambers can differ in their size, so that, depending on the geometric design of the fire protection fastening device, as many reaction chambers as possible with the largest possible area can be used.
  • the respective reaction chamber is fully delimited by the frame.
  • the depth of the reaction chamber extends parallel to the mounting axis. Accordingly, the circumference of the reaction chamber is also defined with respect to an axis parallel to the assembly axis.
  • the reaction chamber is open at the rear and/or the front of the frame. If the reaction chamber on both sides, i. H. on the front and on the back, is open, it is a through hole in the frame. If the reaction chamber is only open on one of the two sides, it is in particular a pocket formed in the frame.
  • a drive element is arranged in each reaction chamber.
  • the drive element is made of thermally intumescent material.
  • the drive element is designed to push the door actuator away from the mounting surface when it is thermally activated, that is to say when it is heated accordingly.
  • the thermally activatable material of the drive element can be activated in a temperature range of 90°C to 200°C.
  • the drive element is in particular a flat, plate-shaped material that can be cut to any size. Since this material is available in certain thicknesses, it is preferably provided that several layers are superimposed to form the drive element. The several layers then together form a drive element.
  • the volume of this material increases, for example by foaming. Due to the fact that the drive element is arranged in the reaction chamber and due to the fact that the reaction chamber is completely delimited by the frame, the drive element only expands in a direction parallel to the mounting axis. The expansion of the drive element in a direction perpendicular thereto is blocked by the full-circumferential limitation by the frame.
  • the frame can be arranged as an independent component between the door operator and the mounting surface. If necessary, a mounting plate can be located between the frame and the door operator. In this arrangement of the frame, the reaction chamber can be open at both the front and the back. What is decisive is that, when thermally activated, the drive element expands in the direction parallel to the mounting axis, as a result of which the door actuator is pushed away from the mounting surface. Whether the frame is pushed away with it or remains on the mounting surface side is not relevant for the basic function of the invention.
  • the reaction chamber is open at the rear in order to push the door operator together with the integral frame away from the mounting surface.
  • the door actuator When the drive element or the several drive elements in the individual reaction chambers are thermally activated, the door actuator is pushed away from the mounting surface, with the external threads on the screws or the associated internal threads breaking, for example. This releases the door operator from the mounting surface, i.e. from the door, frame or wall. In particular, it is assumed that the door operator is on the side of the door away from the fire. Detaching the door operator from its mounting surface avoids overheating the door operator, thereby avoiding ignition of the fluid in the door operator.
  • the fire protection fastening device has a piston plate arranged in the reaction chamber.
  • the piston plate is arranged in the reaction chamber in such a way that the mounting axis is orthogonal to the piston plate. If several reaction chambers are used, there is a drive element in each reaction chamber and a piston plate that is to be used preferably.
  • the piston plate is formed from a rigid material and serves to be displaced by the drive element when the drive element is thermally activated. It is provided in particular that the piston plate is guided in the reaction chamber. The direction of displacement is in particular parallel to the assembly axis.
  • the gap between the piston plate and the reaction chamber should preferably be kept as small as possible so that the intumescent material of the drive element does not swell past the piston plate through the gap.
  • the piston plate can be arranged on the front or the rear of the drive element. Furthermore, it is also possible to arrange a piston plate on both sides of the drive element. Accordingly, two piston plates are then provided per reaction chamber.
  • the piston plates can also be referred to as pressure distribution plates or pressure modulator plates, since they ensure that the pressure applied by the drive element is transmitted over as large an area as possible. They also ensure that the drive element is not uselessly distributed in cavities, for example the jagged rear side of a door operator, in the event of thermal activation.
  • the piston plate is made of metal, for example aluminum. This results in a stiff, lightweight piston plate that is easy to manufacture.
  • a thermally insulating design of the fire protection fastening device is advantageous.
  • the heat input from the mounting surface into the drive element should be as resistance-free as possible.
  • any further heat conduction, especially in the direction of the door operator, should be prevented if possible will.
  • a piston plate, which is arranged between the drive element and the door operator is made of non-metallic, thermally insulating material.
  • the piston plate can also be multi-layered, with at least one layer being made of non-metallic, thermally insulating material.
  • a piston plate, which is arranged between the drive element and the mounting surface is made of metallic, thermally conductive material. This ensures that heat is transferred quickly from the mounting surface to the drive element in order to ensure an early increase in volume of the intumescent material. It can thus be provided that the drive element is surrounded by two different piston plates, in particular by two piston plates with different thermal conductivity.
  • the thermally insulating material in the piston plate it is preferably provided that at least one insulating plate made of non-metallic, thermally insulating material is placed on at least one side of the piston plate.
  • the insulation panel is preferably made of a fiber composite material.
  • the insulation plate When the insulation plate is inserted between the piston plate and the drive element, it is located in particular in the reaction chamber. If the insulating plate is placed on the side of the piston plate facing away from the drive element, it can also be located outside the reaction chamber.
  • the single reaction chamber has a cross-sectional area perpendicular to the mounting axis.
  • This cross-sectional area of the reaction chamber is in particular rectangular, since as many reaction chambers or reaction chambers with a large area as possible can be distributed over the frame with this geometric configuration. However, other cross-sectional areas are also possible. However, it is preferably provided that the drive element and/or the piston plate and/or the insulating plate extends/extend over the entire cross-sectional area.
  • the reaction chamber is preferably on both sides, i. H. on the front and on the back, open.
  • the reaction chamber is open on both sides over the entire cross section.
  • the open rear of the reaction chamber has the advantage that the drive element can be in direct contact with the mounting surface. As a result, the drive element is heated as quickly and adequately as possible in the event of a fire.
  • the drive element can spread out in the direction of the door operator or push the piston plate in the direction of the door operator via the open front side.
  • the fire protection fastening device is designed as flat as possible and is designed as far as possible in such a way that it can be arranged inconspicuously between the door operator and the mounting surface.
  • a depth of each reaction chamber is defined perpendicular to the mounting axis. This depth of the reaction chamber is preferably between 1 mm and 30 mm, in particular between 5 mm and 20 mm. This provides sufficient installation space to arrange the drive element, possibly also the piston plate, in the reaction chamber.
  • the cross-sectional area of the individual reaction chambers is defined perpendicular to the assembly axis. This is preferably between 400 mm 2 and 50,000 mm 2 ; preferably between 900 mm 2 and 10,000 mm 2 .
  • the sum of all cross-sectional areas of all reaction chambers is preferably at least 2,500 mm 2 , in particular at least 5,000 mm 2 .
  • the frame is not an integral part of the door operator, but is arranged between the mounting surface and the door operator or mounting plate. It is provided in particular that the frame has first attachment points for screwing to the mounting surface. Furthermore, second attachment points are formed in the frame, at which the door operator or any mounting plate can be attached to the frame.
  • the attachment points are, in particular, through-holes. In particular at the second fastening points, the through-holes preferably have an internal thread.
  • the fastening points can also be formed by threaded rods, for example.
  • first and second attachment points which are closest to one another preferably form a pair.
  • two first and two second attachment points are provided on the right side of the frame.
  • two first and two second attachment points are provided on the left side of the frame. This means there are two pairs on each side of the frame.
  • the distance between the attachment points of a pair is as small as possible.
  • the distance between the first attachment point and the second attachment point of the respective pair is at most 5 times, preferably at most 4 times, the thickness of the frame.
  • the thickness of the frame is defined parallel to the mounting axis.
  • the frame at its thickest point is decisive.
  • the average thickness of the frame in the area between the attachment points of a pair is decisive. If the distance between the attachment points of a pair is too great, it can happen that only the frame deforms without the door operator detaching from the frame.
  • the invention also includes a first arrangement with a door operator and the fire protection attachment device described above, the frame of the fire protection attachment device being designed as an integral part of the door operator.
  • the door operator has a housing; for example from die casting.
  • the housing there is in particular at least one hydraulic chamber in which the combustible fluid is located.
  • the frame is preferably formed on the rear side of the door operator, in particular the housing.
  • the piston plate can be located on the back of the frame.
  • the invention includes a second arrangement with a door operator and the described fire protection attachment device, wherein the door operator can be attached directly to the frame, in particular can be screwed on.
  • the frame of the fire protection fastening device in turn, can preferably be fastened directly to the mounting surface, in particular screwed on.
  • the invention also includes a third arrangement with a door operator and the fire protection fastening device described, as well as an additional mounting plate.
  • the mounting plate is to be arranged between the fire protection fastening device and the door operator.
  • the mounting plate is attached to the frame of the fire protection attachment device, in particular screwed on.
  • the frame of the fire protection fastening device must in turn be screwed to the mounting surface.
  • the door operator can be connected in the usual way to the front of the mounting plate, in particular screwed. During thermal activation, the mounting plate is pushed away from the mounting surface. The door actuator is released together with the mounting plate.
  • All exemplary embodiments show an arrangement 100 with a door operator 102.
  • the door operator 102 is designed as a hydraulic door closer in the exemplary embodiments.
  • the door operator 102 has an output shaft 103 .
  • the door operator can be connected to a door or frame, for example, by means of a linkage via this output shaft 103 .
  • the door operator 102 is attached to a mounting surface 101 .
  • the mounting surface 101 is formed in particular by a door, frame or wall.
  • a mounting axis 2 is perpendicular to the mounting surface 101.
  • a fire protection fastening device 1 is used to fasten the door operator 102 to the mounting surface 101 .
  • the fire protection fastening device 1 comprises a frame 3.
  • this frame 3 is a separate component.
  • the frame 3 is an integral part of the door operator 102.
