Definitions

  • the present invention relates to a multi-story building with safe access and escape routes in the event of a fire according to the preamble of patent claim 1.
  • the CH 704824 A2 reveals a smoke protection pressure system.
  • fresh air is blown into the areas of a building that need to be protected via ducts.
  • a flap is opened on the fire floor to form an outflow shaft.
  • the chimney effect as well as the wind pressure on the windward side and the suction effect on the leeward side of the building are used. 1
  • the DE102017202543A1 discloses a multi-story building with core zones, with a fire door being provided between a stairwell and the usage areas, with a door between the elevator lobby and the usage areas being locked via a fire control system in the event of a fire.
  • the present invention now sets itself the task of designing a multi-story building with safe access and escape routes in the event of a fire, which ensures right from the beginning of the planning phase that the legal requirements can be fully met, so that complex subsequent replanning and additions are no longer necessary.
  • Multi-story buildings especially those with a large number of floors or a large height, have so-called core zones 1, in which stairwells 11 and / or elevator shafts 12 for elevators F are accommodated in order to enable the transport of people or goods in the vertical direction.
  • the side areas of the floors outside core zone 1 are available as usage areas 2 and can be divided and set up differently depending on the desired use of the building ( Fig. 1a-b ).
  • the usage areas 2 are separated from the core zone 1 with horizontal fire barriers 31 such as fire protection walls 311 and fire doors 312a, 312b, which prevent the spread of fire in the event of a fire ( Fig. 2a-b ).
  • horizontal fire barriers 31 serve not only as fire protection but also as a barrier against water or other extinguishing agents in order to ensure that the core zone 1 is not flooded.
  • a smoke protection pressure system (RDA) 4 generates excess pressure in the core zone 1 so that no gases or gases are released when the fire doors 312a, 312b are opened Smoke can penetrate into core zone 1.
  • RDAs smoke protection pressure system
  • such RDAs are used to keep security stairwells (stairwells with locks in front) smoke-free.
  • the RDA 4 can also be used for the elevator systems, so that the normal elevators F can also be used safely in the event of a fire can.
  • vertical fire- and water-proof fire bars 32 are also provided. These can be designed as floor ceilings 32 installed in the horizontal direction, each of which is arranged after a certain number of floors in the area of usable areas 2.
  • the present invention provides that the vertical fire bars 32 arranged in the horizontal direction are set up as mezzanines 32a, these mezzanines 32a being sealed off from the usage areas 2 above and below in a fireproof and watertight manner ( Fig. 3a ).
  • the building according to the invention is divided into segments, which are completely sealed off from the rest of the building in a fire-safe manner in the event of a fire:
  • the usage areas 2 are divided into several fire protection segments 2'
  • the core zone 1 is divided into several core segments 1' ( Fig. 3b ).
  • the core segments 1' and fire protection segments 2' have a height of approximately 70 to 80 meters.
  • the core zone 1 acts as a shaft, which opens up the fire protection segments 2 'and mezzanines 32a in the vertical direction.
  • Each core segment 1' is connected to at least the mezzanine 32a above or below in such a way that the RDA 4 for this core segment 1' can keep this mezzanine 32a smoke-free in addition to the stairwell 11, the elevator shaft 12 and any elevator lobby 13.
  • the RDA 4 In order for the RDA 4 to function well and to ensure its effectiveness even in extreme weather and wind conditions with different air pressure on different sides and at different heights outside the building, it is recommended to use several RDA 4s per building, preferably one RDA 4 per fire protection segment 2 '. If there are several core segments 1' in a building, separate RDA 4 should be used for each core segment 1'. This makes it possible for a core segment 1' and the associated mezzanine 32a, which is located above or below, to be kept smoke-free at least partially with a single RDA 4 in the event of a fire can be.
  • the proposed arrangement also has the advantage that the RDA 4, as well as the inlets and outlets 41 required for the RDA 4 for the air from outside the building, can be installed in these mezzanines 32a. This ensures that the usable areas 2 are completely independent of the fire protection measures and can be planned freely and without restrictions by the architect.
  • the mezzanines 32a are preferably designed as technical floors 32a, which can be used in addition to the function as vertical fire barriers 32 and as a location for the RDA 4 and for other additional functions.
  • the RDA 4 of a fire protection segment 2' or core segment 1' it is advantageous if it is separated from the rest of the building on at least two sides of the building at both the upper and lower end of the fire protection segment 2' or core segment 1' Channels 41 which, depending on the weather and wind conditions, are used outside the building either as outflow or as afterflow channels 41 ( Fig. 4 ). Since the technical floors 32a are extended over the entire building area, one or more such channels 41 can easily be arranged on each side of the building.
  • each core segment 1 ' the outflow and afterflow channels 41 are connected in the vertical direction to a continuous air shaft, and several such air shafts can also be arranged around the core zone 1.
  • several outflow or afterflow channels 41 are arranged on different sides in each technical floor 32a, each of which is present once for the core segment 1 'above it and once for the core segment 1 'below.
  • outflow and afterflow channels 41 are present on different sides of the building. Because they point in different directions, the outflow path can vary depending on wind conditions. For example, if there is high wind pressure on the west facade, the outflow can still occur on the east or south side. At high altitudes, where the wind load is naturally higher, or in extreme wind conditions, the wind pressure on one side can be so strong that it has a negative influence on the outflow. This influence can be caused, for example, by turbulence or undesirable pressure conditions in the outflow channels 41. In order to avoid such influences, the outflow and afterflow channels 41 can optionally be equipped with a muzzle brake 5. A possible Embodiment of the muzzle brake 5 is in Fig.
  • labyrinth a kind of zigzag-shaped labyrinth being arranged near the mouth of the channel 41 by means of permanently installed components. Since these components contain no moving parts, they are maintenance-free.
  • the built-in, one-way labyrinth dissipates the energy of the wind loads inwards, but still allows it to function as an afterflow opening.
  • the special shape of the labyrinth enables the laminar flow from the outflow channel 41 to the outside, without the risk that extreme wind conditions could create undesirable pressure conditions in the outflow channels.
  • the design of the labyrinth can be as in Fig. 4 shown, by a combination of built-in components with the outer dimension of the channel 41, or just by built-in components that can have different shapes and dimensions. The only important thing is that when there is a correspondingly strong wind pressure from outside, the flow inwards through the labyrinth is slowed down, so that an influence on the pressure conditions in the outflow channel 41 is, if possible, completely avoided.
  • each RDA 4 has at least one supply air channel 42 for the air supply from the outside, which is also in the Technical floor is arranged.
  • a supply air shaft 43 (separate from the air shaft for the outflow) is arranged within or next to the core zone 1, which conveys the supply air from the RDA 4 to the floors above or below.
  • the safety stairwell 11 is connected to the supply air shaft 43 with air outlets 44 in order to generate the RDA overpressure in the stairwell.
  • air outlets 44 can be guided from the supply air shaft 43 into each elevator shaft 12. These air outlets 44 can be located either in the technical floors 32a or in the floors above and below and are separated from the elevator shaft 12 with flaps.
  • each elevator shaft 12 can be flushed parallel to the RDA operation of the safety stairwell 11 if necessary.
  • the flaps can be controlled individually or in groups, so that various ventilation and flushing scenarios can be carried out. Such a control allows the activation of the flushing of the elevator shafts 12 via the user interfaces of the elevator systems, or via a central control, which can be located on the technical floor 32a.
  • General technical equipment for a building in normal operation can of course also be accommodated in the technical floors 32a, such as the power supply with fuse boxes, etc. In the event of a fire, this has the advantage that unnecessary or dangerous equipment can be switched off from the intermediate floors 32a. Special facilities for the event of a fire, such as the water supply to sprinkler systems or the general control of the water supply, are ideally arranged on these technical floors 32a.
  • areas of the technical floors 32a are intended as fire preparedness rooms and fire brigade bases for the fire brigade.
  • Other areas can be used as evacuation rooms for people from the floors below or above so that they can be evacuated from the building in an orderly manner via the safety stairwells 11 or the fire-safe elevator systems.
  • the present invention can be implemented not only in building concepts with a simple facade skin, but also in buildings with a curtain wall or double facade 6. In modern buildings with double facades 6, these can fulfill several functions.
  • the curtain wall 6 can also be useful for energy optimization, as a wind deflector, sound insulation or for shading.
  • the double facade 6 also promotes the functionality of the RDA 4 according to the present invention.
  • Fig. 6 shows how the outflow and inflow takes place via the joints 61 of the curtain wall 6. The flow therefore takes place from the buffer zone 62 in the space between the double facade to the outside without any control; upwards in winter and downwards in summer.
  • the outer facade skin 6 also acts as a wind deflector.
  • the wind forces which can be very strong, especially in tall buildings, are absorbed by the outer facade shell 6, so that undesirable turbulence and unfavorable pressure conditions in the outflow channels are avoided and further measures, such as the muzzle brake 5, are not necessary.
  • the segmentation in the area of the buffer zone of the double facade can be supplemented with swords 63 either without fire resistance (RF1) or with fire resistance.
  • swords 63 can either be in the area of the technical floors 32a or can also be installed on each individual floor.
  • the design and materialization of the swords 63 is based on the basic fire protection concept of the building.
  • the structural design of the swords 63 is of great importance. For example, by fire-resistant swords 63 that protrude over the outer building shell 6, the effectiveness of the vertical fire bars 32 and thus the fire safety of the entire building can be significantly increased. In combination with the use of fireproof materials in the curtain wall 6, a vertical spread of a fire to floors above can be largely prevented.
  • the present invention also has the advantage over conventional systems in connection with an RDA and fire protection measures that less measurement and control technology is required to ensure the functions.
  • RDA and fire protection measures that less measurement and control technology is required to ensure the functions.
  • outflow and wake systems natural physical phenomena such as lift or downforce are exploited or problems due to these phenomena, such as wind pressure, are avoided. This avoids costs, both during construction and later maintenance.
  • Core segments 1 ' which in normal operation connect the different floors and vertical building segments, can be safely used completely for fire fighting and / or evacuation in the event of a fire. They therefore serve as a vertical access axis both in normal operation and in the event of a fire, which connects all fire protection segments 2 'and technical floors 32a with one another. This is achieved by sealing off the core zone 1 and the intermediate floors 32a from the usage areas 2 with fire protection walls 311, doors 312a, 312b and locks or other measures that are water and fire resistant or are automatically sealed off in the event of a fire via the fire control system.
  • each building unit consisting of a fire protection segment 2 ', the core segment 1' adjacent in the horizontal direction and the upper or lower mezzanine 32a connected to it functions self-sufficiently, ie independently of the other building units. It makes sense that the planned RDA 4 and the outer shell of the double facade 6 are not unit-wide. Only the elevator shafts 12 and the safety stairwell 11 are continuous and unit-wide, with the safety stairwell 11 being divided on each mezzanine 32a with a wall with built-in doors and two barometric flaps so that the RDA 4 each works as intended.
  • Another central feature of the invention is the consistent separation of the core zone 1 from the usage areas 2 in the event of a fire by the fire protection walls 311 and the fire protection doors 312a, 312b.
  • the aim is to seal core zone 1 absolutely tightly against heat, smoke and (extinguishing) water, so that not only the users of the elevators in the event of a fire, but also all sensitive components of the elevator systems are effectively protected.
  • the Fig. 7a-b show a possible door construction for the fire doors 312a, 312b, which allows maximum security to be achieved by combining a hinged door 71 with a sliding door 72. With a door blade 73, which is guided in a gutter 75 equipped with a drain 74, the complete, watertight separation of the core zone 1 from the surrounding usage areas 2 can be achieved.
  • the fire doors 312a between the lift lobby 13 and the usage areas 2 can be controlled and are locked in the event of a fire, so that in the event of a fire, the lift shafts 12 and the lift lobby 13 can only be accessed via the pressurized safety stairwell 11 and its upstream fire door 312b.
  • Lift shafts 12 and the lift lobby 13 in the core zone 1 are structurally separated from the usage areas 2 as a “shaft with outdoor climate”.
  • core zone 1 only acts as a closed shaft in the event of a fire.
  • the lift lobby 13 can be accessed from the usage areas 2, for example directly via open fire doors 312a.
  • different security levels can be implemented.
  • a difference in level between the lift lobby 13 and the safety stairwell 11 can prevent extinguishing water from reaching the lift lobby 13 and thus into the lift shafts 12 via the safety stairwell 11. Any extinguishing water that gets into the safety stairwell 11 runs down the stairs before it can overcome the difference in level into the lift lobby 13. In the lower area of the safety stairwell 11, the water can be led away from the core zone 1 via a pipe through waterproof connections of a flight of stairs and the corresponding platform to the stairwell walls.
  • the systems must generate a fresh air flow directed vertically from bottom to top with an output of 7,500 m 3 /h in the pressure maintenance phase.
  • a weak point is always the possibility that several doors may be temporarily blocked due to the movement of fleeing people can be open at the same time and the required fresh air flow is thereby lost.
  • Another weak point is that escapees on the fire floor can take smoke from the burning areas 2 through open doors not only into the security stairwell 11, but also into the elevator lobby 13 and the elevator shafts 12.
  • a first solution to this problem is to ensure that the door between the security stairwell 11 and the elevator lobby 13 on the fire floor is locked so that only part of the core zone 1 is accessible on the fire floor.
  • the refugees are guided down one floor through the security stairwell 11 with pictograms. There the refugees can open the door to the lift lobby 13 without the risk of smoke entering the lift lobby 13 and the lift shafts 12.
  • This measure is additionally supported by the above-mentioned upward flow of fresh air through the safety stairwell 11: Since the escapees move downwards from the fire floor, towards the fresh air, no smoke can be carried into the lift lobby 13 and into the lift shafts 12. If necessary, this door between the security stairwell 11 and the elevator lobby 13 could also be locked on one or more floors above the fire floor.
  • the core zone 1 has a lock 14 between the security stairwell 11 and the usage areas 2 or between the elevator lobby 13 and the usage areas 2 ( Figure 8 ).
  • This lock 14 has at least one door to the usage areas 2 and at least one door to the security stairwell 11 or to the elevator lobby 13, which cannot be opened at the same time and are not open at the same time. As soon as one of these two doors is opened, the other door is locked so that it cannot be opened.
  • the invention is optimized for the evacuation of refugees with mobility restrictions. For example, bedridden patients in a hospital and wheelchair users in a retirement home cannot escape via the safety stairwell 11, but only via the elevators F.
  • a waiting zone 7 is provided in the usage areas 2 next to the core zone 1, in which bedridden patients and Wheelchair users can be collected in a first step and can protect themselves from the fire before they are evacuated in a second step using the elevators F ( Figure 9 ).
  • the waiting zone 7 can, for example, consist of one or more bed rooms that are located next to the core zone 1 and, like the core zone 1, have fire protection walls 311 and Fire doors 312b can be sealed off.
  • the waiting zone 7 can be directly connected to the security stairwell 11 and/or to the elevator lobby 13 and/or to a lock 14. It is important that the waiting zone 7 can also be protected against the ingress of smoke with the excess pressure prevailing in the safety stairwell 11 or in the elevator lobby 13. It is advantageous if a lock effect is also provided in the waiting zone 7, ie that the door of the waiting zone 7 to the usage areas 2 cannot be opened at the same time and is not open at the same time to the door of the waiting zone 7 to the security stairwell 11 or to the elevator lobby 13 or to the lock 14.
  • a ventilation flap is also provided in the waiting zone 7, through which the smoke that penetrates into the waiting zone 7 when the door to the usage areas 2 is opened can escape from the waiting zone 7 can. Due to the excess pressure prevailing in the safety stairwell 11 or in the lift lobby 13 or in the lock 14, the smoke in the waiting zone 7 is blown away through the ventilation flap as soon as the door to the safety stairwell 11 or to the lift lobby 13 or to the lock 14 is opened is, and without in the core zone 1 to penetrate.
  • a major advantage of the invention is the use of the stairwells and lifts both in normal operation and in the event of a fire, so that those fleeing can use the routes they are used to even in the event of a fire.
  • Experience shows that it is more difficult to behave correctly in a stressful situation, so that it is not always easy for those affected to find escape routes despite appropriate instructions, training and marking. If these escape routes are the same ones that are used every day, this is much easier and the appropriate instruction and training in the event of a fire is simplified.
  • the full potential of the invention is particularly evident in hospital use. With a single RDA 4, the security stairwell 11, the lift shafts 12, the lift lobby 13, the locks 14 and the waiting areas 7 are effectively protected against smoke.
  • Moving elevators cause a piston effect that changes the pressure conditions in the elevator shafts 12:
  • the elevator F builds up excess pressure in front of it.
  • the moving elevator F builds up a negative pressure or suction effect behind itself.
  • elevators F are moved at speeds of up to over 70 km/h
  • the lift shafts 12 therefore generate significant pressure differences.
  • the lift shafts are therefore connected to the outside in each mezzanine 32 via a first and a second pressure equalization channel 51, 52 so that they are in permanent pressure equalization with the outside climate.
  • the first pressure equalization channel 51 serves to relieve the excess pressure of the piston action of the elevator F to the outside.
  • the second pressure compensation channel 52 is used for the follow-up air from outside to compensate for the negative pressure of the piston action of the elevator F.
  • the first pressure compensation channel 51 has a check valve, which only allows excess pressure to be released to the outside.
  • the second pressure compensation channels 52 each have a controllable valve, which can be opened and closed by the fire control system. In order to avoid smoke being drawn into the lift shafts 12 via the second pressure compensation channel 52, the valve of the second pressure compensation channel 52 of all mezzanines 32, which are located above the fire floor, is closed by the fire control system.
