Definitions

  • the invention relates to a suspended fire-retardant covering provided with spraying elements for load-bearing ceilings and with an intake opening of an exhaust air fan provided above the covering.
  • Known fire-retardant cladding for example in the form of suspended ceilings, have the function of increasing the fire resistance of the load-bearing ceilings. The main focus is on ensuring that the fire cannot come into direct contact with the load-bearing ceiling.
  • Such cladding is often also equipped with sprinkler systems, which means that spray heads are automatically activated at a certain temperature, for example to contain local heat. The liquid dispensed by the spray heads is aimed directly at the floor area of the room to be secured.
  • the aim is also to give the possibility of being able to exhaust the smoke that arises at the source of the fire quickly and using normal exhaust air fans, the suction openings of which are arranged above the fire-retardant cladding.
  • the cladding is composed of curved ceiling elements, with their side edges in collecting channels for liquids emitted from the spray elements, preferably in the form of spray heads or nozzles, while maintaining a distance from the walls of the collecting channels and to the side edge of each adjacent ceiling element are included.
  • the advantage of the cladding according to the invention can be seen in the fact that the ceiling elements can be sprayed with liquids, which increases the fire resistance.
  • the continually newly used and controlled drained water is extremely effective energy absorber and emission carrier for the smoke. The water emitted by the spray heads reaches the gutters in which the side edges of the ceiling elements are arranged.
  • suction openings of suction fans which are known to be arranged in the area of the load-bearing ceilings, then suck out the air through slots which are formed between the side edges of the ceiling elements and the edge walls of the collecting troughs.
  • the particularly rapid and thorough suction of the air or smoke through the slots can be explained as follows. A cavity is created between the components closing the room and the cladding. In it, the flow resistance is many times lower than in the slots that can be called suction joints. This is why a vacuum builds up in the ceiling cavity, which ensures even suction across the entire surface of the cladding. In contrast, without the cladding according to the invention, the air or smoke is distributed over a large area of the room.
  • the ceiling elements can be arched in the shape of a cross, barrel or channel.
  • the shape of the ceiling elements can be based on the simplicity of manufacture or the decorative effect they are supposed to have, for example, to be integrated into the sales area of a department storey as a decorative element.
  • the spray elements can be designed in such a way that both the surface facing the room and the surface on the ceiling are covered. This increases the fire resistance.
  • the collecting channels are connected to one another by means of cross-shaped connecting pieces or, T-shaped connecting pieces at the ceiling edges at the crossing points, wherein preferably different levels can be introduced into these stowage plates for the storage of liquid.
  • the advantage can be achieved that an increased energy consumption by the liquid can be achieved by raising the liquid level.
  • the height of the liquid can also be adjusted with the aid of the baffle plates in such a way that the slot between the walls of the collecting troughs and the side edges of the ceiling elements is closed. The extracted air or the extracted smoke is then cooled even more when it penetrates.
  • a cross-shaped connecting piece is pressed from below against the gutters and has a bore through which a plug pin or the like is passed for fastening the cladding to the load-bearing ceiling and engages in a bore of a cross-shaped suspension part with curved legs, which engages from above presses the gutters in the area of the joints of the ceiling elements.
  • a cross-shaped or T-shaped receptacle takes up the gutter of the ceiling elements at the intersections of the gutters, which has a bore for the passage of the plug pin or the like.
  • the ceiling elements in the area of the gutters preferably have ceiling-mounted dirt deflectors in the form of a protective net on.
  • the cladding according to the invention also has the advantage that the water that has penetrated through a ceiling, for example, cannot reach the floor area of the shielded room. Rather, it is discharged along the ceiling-side surface of the ceiling elements into the gutters, for example to be fed to a downpipe in which the gutters open.
  • the teaching according to the invention accordingly provides a cladding that is simple in construction, but not only increases the fire resistance of the load-bearing ceilings, but at the same time prevents fire-fighting water from getting from one floor to the floor area of the floor below.
  • the lower edges of the gutters should preferably be arranged at the same distance from the floor.
  • the intersecting Auffan g can run from U-profiles are made, the webs of which lie in a plane, wherein the collecting channels are themselves divided into mutually parallel first and second collection channels.
  • the second collecting troughs can then be hooked into the slots of the width of the second collecting troughs provided in the legs of the first collecting troughs.
  • the former In order to allow the liquids collected in the gutters to flow away without difficulty, in particular to be able to transfer the liquid well from the second to the first gutters, the former have an intermediate floor running parallel to the webs and at a distance from the webs that is the height between the webs Webs and the insertion slot of the first gutters corresponds.
  • the first collecting troughs having the slots are preferably load-bearing or connected to load-bearing elements.
  • sleeves extend from the webs of the first collecting troughs to at least the upper edges of the legs, the continuous ones Openings of the sleeves for receiving fastening elements for the cladding or for carrying out supply lines are formed.
  • the pipeline for the supply of liquid to the spray heads simultaneously represents the suspension for the cladding.
  • a suspended cladding 10 below a load-bearing ceiling, which is composed of individual ceiling elements 12.
  • the latter are preferably made of thin-walled material.
  • the ceiling elements 12 are arched in the shape of a cross arc. The edges at the opening of the arched cross-shaped arch can be of equal length, so that each ceiling element 12 forms a square surface in a plane running parallel to the floor surface of the sales area.
  • the base area of the cross-arched ceiling elements 12 can also be rectangular or trapezoidal.
  • the ceiling elements 12 are also arranged next to one another at the same height.
  • the ceiling elements 12 protrude with their lateral edges 14 into collecting channels 16 which are open on the ceiling side upwards.
  • the gutters 16 have two parallel lateral walls 18 which merge into a V-shaped base part 20. 4 and 5, however, the gutters consist of U-profiles, in which the side walls or legs 18 are connected by a web 24 running perpendicular thereto.
  • edges 14 of the ceiling elements 12 are of cruciform receiving pieces 30, which are the distance from the walls 18 of the gutters 16 and the base parts 20 and 24, respectively hold, recorded. At the same time, the distance between the adjacent edges 14 of the ceiling elements 12 is fixed by the receiving pieces 30 and an opening or a slot of a predetermined size is left free.
  • the gutters 16 are arranged below the ceiling elements 12 along the edges 14. This results in 12 intersections of gutters 16 at the corners of the ceiling elements, which run in mutually perpendicular directions. Furthermore, cross-shaped connecting pieces 34 or T-shaped connecting pieces 36 can be provided, by means of which the collecting channels 16 are assembled at the crossing points.
  • the covering 10 consisting of the ceiling elements 12 is suspended from the load-bearing ceiling.
  • a cross-shaped suspension part 38 with four curved legs 40 is provided, which is fastened to the load-bearing ceiling and has a bore 42.
  • the bore is preferably surrounded by a sleeve extending from the bottom of the gutters and extending at least up to the height of the upper edge of the connecting piece or the gutter.
  • FIG. 4 shows a corresponding bore surrounded by a sleeve 26, which is used to carry out fastening means for suspending the cladding according to the invention or to carry out supply lines such as electrical cables are determined.
  • the upper opening of the sleeve 26 must of course be above the upper edge of the legs 18 in order to prevent liquid passage through the bore surrounded by the sleeve 26 when the gutter is completely filled with liquid).
  • a cross-shaped connecting piece 34 is pressed against the gutters 16, which has a bore through which a plug pin 44, an elongated screw or other fastening means can be passed, which protrudes into the bore in the suspension part 38 and is brought into engagement therewith.
  • the hanging part 38 presses with its four arcuate legs 40 against the collecting troughs 16.
  • the adjustable engagement of the plug pin 44 or the like in the hanging part 38 sets the strength of the pressure of the connecting piece 34 against the collecting troughs 16.
  • the gutters 16 are arranged with their connecting pieces 34 and 36 at the same height from the floor.
  • the collecting channels 16 are preferably connected at the end to a downpipe in order to allow liquids to be discharged to flow into a collecting container or into a drain.
  • FIG. 5 shows a further embodiment of a crossing point of collecting gutters which intersect.
  • the gutters are U-profiles that - as mentioned - run parallel to each other Legs 18 and a web 24 connecting them are formed.
  • the schematically shown collecting troughs are a main collecting trough or also first collecting trough 52, into which secondary collecting troughs or second collecting troughs 54 and 56.m open.
  • an insertion slot 58 is provided in the legs 18 of the collecting trough 52, into which the secondary collecting troughs 54 and 56 are hung. The width of the insertion slot 58 is equal to the clear distance between the legs of the gutters 54 and 56.
  • the transition between the gutters is designed in such a way that it is tight in order to prevent liquids from escaping in the transition area.
  • the edges of the gutters 54 and 56 are bent over in such a way that they come to rest on the inner walls of the legs 18. The bent edges can then be connected to the leg walls by any fastening means. A sealant can then preferably be introduced in the overlapping regions between the leg walls and the bent edges.
  • an intermediate floor 60 running parallel to the web is provided, the distance to the web corresponding to the height between the web and the lower edge of the insertion slot 58.
  • the intermediate floor 60 can of course not be ascertained by the observer of the paneling according to the invention, so that the visually constant and regular impression of the paneling according to the invention is not disturbed.
  • At least one spray element 46 preferably in the form of a spray head or nozzle, is arranged within the curvature of each ceiling element and is supplied with liquids, preferably extinguishing liquids, via a line (not shown).
  • the spray element 46 is designed so that there is the possibility that the liquid to be dispensed covers both the surface of the ceiling elements 12 facing the room and the surfaces on the ceiling with a liquid layer. The liquids released by the spray elements 46 are then collected in the collecting channels 16 and 52, 54, 56 in order to drain off.
  • baffle plates 48 are arranged in the intersection area of the collecting channels 16, that is to say within the cross-shaped connecting pieces 34 or T-shaped connecting pieces 36, as a result of which the liquid level in the collecting channels 16 can be adjusted.
  • This has the advantage that the air extracted from the rooms, which must pass through the aforementioned suction joints or slots, depends on the distances between the channels 14 the ceiling elements 12 and the legs 18 of the gutters 16 are formed, more or less comes into contact with the liquid. This cools down. This is particularly advantageous if, for example, smoke has to be extracted in the event of a fire.
  • the cooling opens up the possibility of extracting the smoke through conventional suction openings of fans arranged above the cladding, which would normally be put out of operation, however, if the smoke is too high in temperature.
  • the baffle plates 48 can even be designed such that the joints or slots between the edges 14 and legs 18 are fully closed. Accordingly, in order to be able to extract air or smoke coming from underneath the casing 10, a corresponding negative pressure must prevail above the casing 10.
  • the area between adjacent ceiling elements is provided with a dirt deflector 50 in order to ensure that the area between the collecting channels 16 and the ceiling elements 12, through which air or smoke is sucked in, is not clogged, as a result of which the functionality of the panel 10 according to the invention would be questioned.
  • the dirt deflector 50 u. a. have the shape of a protective net or a perforated plate.
  • the cladding according to the invention not only increases the fire resistance of the supporting blanket shielding it, at the same time a rapid suction of the resulting smoke takes place, but at the same time prevents that, for example, extinguishing water can penetrate through blankets without being underneath Floor area to be affected.
  • the load-bearing ceiling above it is shielded from direct fire influence.
  • a spread of fire towards the load-bearing ceiling is made more difficult by spraying and covering the covering 10, which consists of the ceiling elements 12, with liquid. This spraying makes the spread of fire towards the ceiling more difficult, whereby not only the surface facing the room but also the surface on the ceiling can be covered with a liquid film.
  • the liquids flowing along the surfaces of the ceiling elements 12 enter a collecting trough which is designed in such a way that the liquid does not have to flow off directly, but rather can be stowed therein to the desired extent.
  • This has the advantage that the air or the smoke coming from the room, which is sucked through the joints or slots formed between the gutters and the edges of the ceiling elements, is cooled, which ensures that the exhaust fans used remain operational, since the extracted air or smoke does not have an impermissibly high temperature.
  • the cladding 10 is composed of a large number of ceiling elements -12, that is to say the suction slots are evenly distributed over the entire ceiling area, the smoke originating from a fire source is sucked in directly vertically or almost vertically upwards towards the ceiling. This avoids the risk of the entire room being filled with smoke or smoke, which could result in a risk of poisoning of the people inside.
  • the cladding 10 prevents, for example, extinguishing water, which can come from a floor above it, from entering the shielding room.
  • the water penetrating through a ceiling is in fact guided along the ceiling-side surfaces of the ceiling elements into the collecting channels 16 and 52, 54, 56, in order to subsequently flow, for example, into a collecting container. This ensures that the damage caused by a fire remains limited to one floor and that fire water on the floors below cannot cause any damage.
