Definitions

  • the invention relates to a fire protection and smoke extraction device for ventilation and smoke extraction systems comprising at least one arranged in a housing shut-off, said housing is insertable into a ventilation or smoke extraction and wherein the shut-off in its closing the cross-section of the housing closed position seals are assigned.
  • Fire protection systems with shut-off elements are known for fire. They close a ventilation duct, which is passed through a wall, for example, to prevent the transmission of sparks, smoke and heat in an adjacent room. Also smoke extraction with shut-off elements are known. Normally, these can be closed; in the event of a smoke extraction, they open despite fire exposure in order to enable smoke extraction via smoke extraction ducts or ducts.
  • the invention relates to a combined fire protection and smoke extraction device, the shutoff closes a ventilation or smoke extraction duct against transmission of fire and their shut-off for the passage of smoke can also be opened.
  • a fire protection and smoke extraction can be closed in case of fire and be opened again after this closing for an assumed smoke extraction.
  • the seals of the fire protection and smoke extraction device must ensure a tight seal of the ventilation or smoke extraction system in the event of shutdown, in the event of shutdown Opening case or Wiederöschensfall but they must not hinder the movement of the shut-off.
  • the invention has for its object to provide a fire protection and smoke extraction device mentioned above, which improves both a tight barrier in case of fire and an opening and reopening for the discharge of smoke allows.
  • each seal has at least one sealing section made of intumescent material, which is arranged in the longitudinal center plane of the shut-off in its closed position, and preferably in direct contact on both sides each a sealing section of non-intumescent material is assigned, wherein the sealing portions in wells Wall of the housing are arranged.
  • At least one sealing section of intumescent material is used for the seal.
  • intumescent material expands at higher temperatures, it can thus fill a gap between the housing wall and shut-off completely and seal. Therefore, this material has been proven in fire protection devices with shut-off.
  • the fire protection device according to the invention is also a smoke extraction device, so that the shut-off is also open for smoke removal in case of fire to comply with the relevant particular European standards.
  • the intumescent material must not hinder this opening.
  • the invention proposes that the intumescent material is preferably protected temporarily or for a required period of time against an attack of its expansion causing heat. In direct contact are on both sides of the sealing section of intumescent other sealing sections Non-intumescent material provided that protect the Intumeszenzmaterial against the attack of heat so far. This is especially true when the pivotable shut-off is in its closed position. Then it is associated with a portion of the wall of the housing. In this area, the seals are arranged at the same time.
  • the sealing section of intumescent material is located, flanking each longitudinal side of this sealing section, the sealing sections are arranged from memoriintumeszenzmaterial. In this way, the sealing portion of Intumeszenzmaterial is housed so that acting heat can not hit directly on this Intumeszenzmaterial.
  • the fire protection and smoke extraction device can withstand fire attacks for a time in this manner solely due to the functionality of the sealing sections made of non-intumescent material.
  • the sealing sections do not change so much that opening or reopening of the shut-off element is prevented. For a time later subsequent smoke extraction process thus the shut-off can still be opened.
  • the fire protection and smoke extraction device according to the invention If the fire protection and smoke extraction device according to the invention is not used for the smoke extraction process, it will and / or will remain closed and then be subjected to more fire. In this case, after a period of time required for a possible opening of the shut-off element, the seals of non-intumescent material gradually lose their heat-insulating and sealing effect due to the temperature rise. This gradually reduces the protection of this sealing section of non-intumescent material. It is increasingly transferred heat to the intumescent, so that it then reacts and expands. Then a setting of the shut-off with the intumescent material and a dense and stable fire protection effect is produced.
  • the sealing portions are arranged in recesses of a wall of the housing. Both the intumescent material sealing portion and the non-intumescent sealing portion may be disposed in recesses.
  • the free inner cross-section of the housing is thereby extended, in particular, the pivoting movement of the shut-off element is not hindered by protruding into the pivoting sections.
  • a larger recess than at least one recess for the sealing sections of non-intumescent material is provided for the sealing section of intumescent material.
  • the sealing portion of intumescent material is further away from the inner cross section of the housing, whereby its isolation from heat attack can be improved.
  • a cavity is formed, which allows the intumescent material to expand slightly despite the shielding through the sealing sections made of non-intumescent material, without hindering the movability of the blocking element. Only when the heat attack continues, the intumescent expands so far that it bridges this cavity and applies to the shut-off.
  • a seal of Fishintumeszenzmaterial protrudes into the pivoting of the shut-off in the region of its closed position.
  • This protruding seal can form a stop for the shut-off. Since the protruding seal projects in the region of the closed position of the shut-off in the pivoting path, the shut-off is at stop on the protruding seal in its closed position. Thus it is associated with the further seal of non-intumescent material and the seal of Intumeszenzmaterial.
  • the intended sealing portions may each be strip-shaped. Such strips can be arranged side by side, a strip of intumescent material is flanked on both sides by a strip of non-intumescent material.
  • the non-intumescent material seals may be formed from mineral materials, glass silk or silicates, or combinations of these materials.
  • the fire protection and smoke extraction device has a cuboid housing 1, in which a shut-off element 2 is pivotally inserted.
  • the housing 1 is covered on its outside with a peripheral frame 3, which is placed on the walls 4 of the housing 1.
  • FIG. 4 and in FIG. 9 show in the respectively open position of the shut-off element 2 on the inside of a housing 4 strip-shaped sealing portions. These are each three sealing sections, which in detail in the enlarged views FIG. 5 and FIG. 10 are explained.
  • FIG. 5 the longitudinal center plane of the shut-off element 2 is illustrated by a dashed line 5.
  • a first sealing portion 8 is arranged from Intumeszenzmaterial.
  • This sealing section 8 of intumescent material is bordered on each of its longitudinal sides by a sealing section 7 of non-intumescent material.
  • FIGS. 1 to 5 are the sealing portions 8, 7 arranged in a recess of the wall 4, while the largest recess is provided for the sealing portion 8 of intumescent material. Above the sealing section 8 of intumescent material, a cavity 6 is provided.
  • depressions are provided in the wall 4 of the housing 1 for the sealing portions.
  • a first sealing section 7 made of non-intumescent material and the sealing section 8 of intumescent material are arranged in a depression, a second sealing section 7 of non-intumescent material is arranged in a smaller depression.
  • This section 7 of Fishintumeszenzmaterial also protrudes further into the interior of the housing 1, thereby forming this section 7 a stop for the pivotal movement of the shut-off element 2.
  • a cavity 6 is provided above the portion 8 of intumescent material.
  • the walls 4 of the housing 1 are preferably made of a silicate material.
  • the placed on the walls 4 surrounding frame has in its interior a metallic profile 9, which is covered with silicate sections 10.
