Definitions

  • the invention relates to a Feuerschutzabchluss and / or Rauchschutzab gleich for closing a cross section of a building, consisting of a plate-shaped closure element, which consists at least partially of glass, preferably a fire protection glass, and a mecanicelememt enclosing frame which is krafstchlüssig connected to a building part.
  • Such a fire protection is, for example, from the DE 196 35 409 A1 known.
  • the closing element consists of a pane of fire-resistant glass, which is encircled by a cross-sectionally U-shaped metal profile. At this metal profile, the hinges for mounting the door leaf and also the handle set and a possible door closer are attached.
  • the revolving, sturdy metallic U-profile has the output to prevent uncontrolled or excessive discarding of the door in case of fire. Only through the interaction of the enclosing profile of the end element and the equally solid executed steel frame, the fire protection is to fulfill its protective function even in case of fire, which is precisely defined in the provisions of EN 1363-1 and EN 1634 Part 1.
  • the thickness of the frame elements is usually several times greater than the thickness of the fire-resistant glazing.
  • a metallic, d.b. more opaque, frame in a glass door at all as disturbing, since often the character of a "glass door” is desired.
  • the invention is based on the object to provide a fire protection, in which the final element to the highest possible proportion, preferably even completely made of fire-resistant glass, without the risk of uncontrolled distortion of the matters exists in case of fire, thereby jeopardizing compliance with fire protection standards could be.
  • the cover is provided on both sides next to the receiving groove for the fire protection strip with a parallel extending retaining groove for receiving a respective holding portion of an elastic sealing profile, the spans the fire protection strip.
  • the end of the end element comes to rest.
  • the frame in particular the base profile, is provided on the side facing the building part with a receiving groove for receiving a fire protection strip.
  • the foaming that occurs then leads to an automatic sealing of the gap area between the frame and the building part, even if this gap area has an irregular shape and size.
  • the closing element essentially consists entirely of fire protection glass or is an all-glass door leaf.
  • the definition of the terms "complete” or “all-glass” is not intended in the context of this application to preclude the fact that on the one hand functional parts such as handle set, bands or Door closers are made of metallic materials or frontal surfaces of the fire glass, for example by means of film strips or thin metal strips are sealed to protect against environmental influences sensitive sodium silicate, which is in the usual Feuerscbutzverglasung between the individual glass layers, from contact with air and water.
  • the idea can additionally be used, the existing in conventional fire protection statements in the edge region of the closure element and thus movable, frame-like reinforcements in the frame, i. a stationary component, to relocate. In the resting state of the stabilizing agent, these are not within the cross section of the terminating element and therefore do not affect its appearance in any way.
  • a fire protection according to the invention it is therefore possible to make the end element completely made of fire-resistant glass, of course, the handle set or bands for the storage of the end element or a door closer and a lower smoke protection seal continue to be made of metal.
  • the stabilizers only then come into action and are only visible when the fire actually occurs. Only in this case, stabilizing agents are needed in the edge region of the end element, as in the normal operating state, the strength of a glass entire closure element is quite given, such as glass doors in the normal version, ie without fire protection function, have proven for some time.
  • the stabilization Exxungsmittel are arranged outside the visible cross section of the closure element, if they have to fulfill any function, whereas in the known fire protection statements stabilizing means, for example in the form of rotating frame elements are always firmly connected to the closing element and therefore the optics in not affect negligibly.
  • the frame as a location for the stabilizer in the non-active state is a particularly advantageous place, as there is usually sufficient space available to accommodate the stabilizing agent including its self-acting drive, without the optical properties of the frame are adversely affected ,
  • these sunk, ie, for example, completely plastered, installed so that when using a glass whole closure element no metal parts are more visible to the viewer when the final element, for example, between opposite walls and between the ceiling and floor of a Flures extends and the frame is flush-mounted in walls, ceiling and floor or plaster or floor covering.
  • the stabilizing agents are within the limited by the frame cross-section that the edge regions of the end element can support and thereby prevent excessive distortion of the same and resulting flame passage safely.
  • the stabilizing function is particularly good when the terminating element is bilateral, i. from its two sides of Stabilmaschinesffenn supportable. Also, the stabilizing means should extend in an elongated manner parallel to the end faces of the closing element, in order to enable the widest possible and not only selective support in case of fire.
  • the stabilizing agents contain an activatable heat-activatable intumescent, in particular sodium silicate.
  • an activatable heat-activatable intumescent in particular sodium silicate.
  • the invention further ausgestaltend is provided that the stabilizing agent at least one stabilization profile, in particular a. Have steel profile. In this way, a very high strength of the stabilizing agent is achieved, so that even very large internal deformation forces of the closing element , especially in very uneven exposure to heat, can be supported.
  • the stabilizing agents are formed by a hollow profile filled with an intumescent agent, which has an opening facing away from the direction of movement of the stabilizing agent.
  • an intumescent agent which has an opening facing away from the direction of movement of the stabilizing agent.
  • the stabilization profile is slidably mounted in a guide profile, wherein the guide profile and / or the stabilization profile have stop means which define a Stabilisiergswolf in which the stabilization profile has emerged maximally from the frame.
  • stabilization profiles and the guide profiles thus act together according to the telescopic principle, which allows the absorption of transverse forces, in particular even in the extended state.
  • the stabilization profile is U-shaped in cross-section with feet projecting outwards at the ends of its legs and the guide profile is formed inverted in a U-shaped cross-section with hooks projecting inwards at the ends of its legs.
  • two guide profiles are combined to form a base profile and that a stiffening profile is arranged between the guide profiles.
  • the latter has the task of ensuring the rigidity of the frame construction, in particular to absorb the forces that are caused by the bands movable, for example, tiltable, pivotal or hinged mounted end elements to accommodate.
  • the base profile consisting of a lower part, which has the opposite legs of the two guide profiles, and a non-positively connected, in particular welded, upper part, which has the mutually facing legs of the two guide profiles.
  • the frame has a cover, which covers the stabilization profiles and / or the guide profiles and with predetermined breaking points is provided, which limit an opening area, which can be lifted by the swelling Dämm Anlagen briefly.
  • the inherent stabilization function for the edge regions of the end element is not to be considered.
  • the places where the stabilization profiles emerge in case of fire, can be made completely invisible, so that such a frame can also meet very high aesthetic requirements. Only in case of fire, the cover profile of such a frame breaks exactly at the points from which emerge the stabilization profiles.
  • the material thickness in the area of the predetermined breaking points and the quantity and type of intumescent agent must be coordinated in such a way that a secure emergence of the stabilization profiles is ensured.
  • the cover profile is connected to a holding profile, preferably via latching lugs, and the stiffening profile is arranged between the holding profile and the cover profile, this results in a very space-saving positioning of the stiffening profile between the mutually parallel stabilization profiles together with the associated guide profiles.
  • Fig. 1 shows a view of a fire protection cover 1 in the form of a glass door, consisting of a closing element 2 in the form of a door leaf, which consists of a holding set 4 in addition to a handle set 3, bearing pin 4a and a door closer 5 completely made of a fire-resistant glass of known type, and a frame. 6 , which is non-positively, in particular by means of screws, connected to a building part 7 in the form of a wall.
  • the frame 6 is substantially complete by one on the building part 7 after the Zargeneinbau applied plaster layer P covered and runs along the two vertical end faces of the door panel and at least along the horizontal upper end side, if necessary, the horizontal lower, ie would then be embedded in the floor.
  • the frame has a base profile 8, which consists of steel and is designed in two layers in its central region 9, because there are an upper part 10 and a lower part 11 of the base profile 8, for example, connected by welding. Alternatively, however, is also a one-piece design of the base profile 8 into consideration.
  • Upper part 10 and lower part 11 of the base profile 8 together form two guide profiles 12, which are arranged on both sides of the central region 9.
  • the guide profiles 12 have in cross section the shape of a U and have at the ends of their legs 13 each inwardly projecting feet 14, which take over the function of stop means.
  • a stabilizing profile 15 is arranged, which also consists of steel and is U-shaped in cross section, wherein the two U-sections of the guide profiles 12 and the stabilizing profiles 15 are arranged rotated by 180 ° to each other.
  • At the ends of the legs 16 of the stabilizing profiles 15 outwardly projecting hooks 17 are arranged. The hooks 17 prevent the stabilization profiles 15 from escaping from the guide profiles 12 and cause a limitation of a relative movement of guide profiles 12 and stabilization profiles 15 to each other.
  • the stabilization profiles 15 are substantially completely filled in their interior with an intumescent agent 18, in particular a sodium silicate, which swells up under the influence of heat.
  • an intumescent agent 18 in particular a sodium silicate, which swells up under the influence of heat.
  • the fire protection strip 20 also consists of a heat-swelling intumescent, such as sodium silicate.
  • the base profile 8 is covered by a cover profile 21, which has a flat U-shape in cross section.
  • the cover 21 is connected in its central region 22 via recesses 23 with locking lugs 24 of a retaining profile 25 which extends in the central region of the base profile 8 between the two guide profiles 12.
  • the retaining profile 25 also has a U-shape and takes in its interior - limited by the central region 22 of the cover 21 - a stiffening profile 26.
  • the stiffening profile 26 is in cross section essentially U-shaped and has in its two edge regions 27 each have a plurality of folded sheet metal layers, whereby the resistance moment can be significantly increased.
  • the existing steel reinforcing profile 26 is from the DE 196 51 699 C1 known, so that can be dispensed with further explanations at this point.
  • the cover profile 21 has in its two edge regions 29 each opening portions 30 which are connected via predetermined breaking points 31 with the remaining portions of the cover 21.
  • the predetermined breaking points. 31 are defined by notches 32, which are introduced from the back of the cover in the surface and therefore are not visible from the outside.
  • the cover profile further comprises a flat receiving groove 33 into which a fire protection strip 34 is inserted.
  • a fire protection strip 34 In the event of fire, the heat-swelling material of this fire protection strip 34 leads to a seal between the frame 6 and the end face 35 of the end element 2 or its delimiting edge regions of the viewing sides.
  • a retaining groove 36 On both sides of the receiving groove 33 is in each case a retaining groove 36, in each of which a holding portion 37 of an elastic material, in particular of silicone elastomer, existing seal 38 is inserted.
  • the seal 38 spans the fire protection strip 34 and ensures even in the "cold state" for a seal between the end face 35 of the end element 2 and the frame 6, so that the fire protection 1 complies with the relevant smoke protection standards.
  • the seal 38 is destroyed at temperatures above 200 ° C, so that the fire protection strip 34 consequently enters the sphere of influence of high temperatures, and then - as already indicated above - takes over a sealing of the gap area against a flame passage.
  • the fire protection strip 34 may be covered for reasons of appearance with a thin metal profile having the color of the cover 21. In this way it is prevented that can be looked through the crystal clear material of the seal 38 on the color possibly deviating fire protection strip.
  • Fig. 3 shows the fire protection closure 1 in a state in which the left stabilization profile 15 has emerged from the frame 6 after exposure to heat by foaming the intumescent agent 18.
  • the swelling Dämm Anlagenslavner acts like a hydraulic drive medium for the "Kobu” in the form of the stabilization profile 15, since the located behind this "cylinder space” is completed and the pressure generated during swelling can be reduced only by displacement of the stabilizing profiles 15 to the outside.
  • the cover profile 21 is broken in the region of the left opening area at the predetermined breaking points, 31.
  • the on the "hot side” stabilization profiles 15 are located in FIG. 3 In its stabilization position, in which the hooks 17 rest on the legs 14 of the legs 13 of the guide profiles 12, so that a further exit movement of the stabilizing profiles 15 is prevented.
  • the stabilizing profile 15 is located within the cross section of the closing element 2 and can therefore be Support edge regions 39 and therefore prevent excessive distortion.
  • the tightness against a flame passage through the gap between the end face 35 of the end element 2 and the frame 6 is through the Dämm Anlagen brieflyner in this.
  • Condition activated fire protection strip 34 taken.
  • the insulating layer is also located in the space between the edge regions 39 of the end element 2 and the leg 16 of the stabilization profile 15, so that the support function of the stabilization profile 15 is an indirect.
  • Fig. 4 shows how the stabilization profiles 15 are located on both sides of the fire protection closure 1 in the activated position and thereby, if necessary, can support the closing element 2 in both directions.
  • the respective (temporal) swelling behavior of the intumescent of the fire protection strip 34 and the stabilization profiles 15 and the concrete deformation of the end element 2 it is possible that in places both stabilization profiles 15 are activated, whereas at other points of the frame. 6 only the stabilizing profile 15 is activated on one side of the end element 3. In any case, it could be demonstrated by means of the corresponding fire tests that the relevant standards could always be reliably adhered to in connection with the seal caused by the fire protection strip 34.
