Definitions
- the present invention concerns a smoke evacuation shutter or fire damper with a roller shutter valve, comprising:
- Smoke evacuation shutters and fire dampers are fire safety devices designed to respectively prevent the spreading of a fire through a building, and evacuate smoke at the fire scene.
- Both safety devices comprise a frame defining a passage and a valve allowing regulate the opening of the passage in the frame, whereby the valve is connected to a spring that, in case of an alarm, moves the valve from an armed position to an alarm position.
- Fire valves are usually open in normal conditions (armed position) as they are installed in ventilation ducts.
- Smoke evacuation shutters are usually kept closed in normal conditions (armed position).
- smoke evacuation shutters are configured to fully open or fully close in case of a fire.
- the smoke evacuation shutters remain closed.
- the fire plan requires the smoke evacuation shutter to open to an intermediate position wherein the passage through the corresponding frame is restricted in view of an open position of the valve, yet not fully closed.
- Roller shutter types of valves are one of the types of valves that can be used in fire dampers or smoke evacuation shutters and have the advantage of a limited depth dimension (dimension in the direction of the air flow through the passage when the valve is open) versus other types of valve such as pivoting blade valves. For that reason, roller shutter types of valves are beneficial for use when renovating buildings where space restrictions often apply.
- the present invention concerns a smoke evacuation shutter or fire damper with a roller shutter valve, comprising:
- the present invention thereby allows automation of the opening/closing of the valve to a predetermined intermediate position by programming or steering the electric drive means and hence no longer requires the use of physical stopping means mounted in the frame of the safety device.
- the present invention also concerns a method of controlling a safety device selected from a smoke evacuation shutter or a fire damper, said safety device comprising:
- a smoke evacuation shutter according to the present invention comprises a frame defining a passage and a roller shutter configured to move between an open position allowing an air flow through said passage and a closed position shutting of the passage.
- the frame 1 is in this case made of two upright guides 2, a top profile 3 and a bottom profile 4 that define a rectangular passage 5 in between them.
- the dimensions of the passage 5 depend on the specific requirements of the building wherein the smoke evacuation shutter is applied.
- the frame 1 is preferably manufactured in a heat resistant material such as aluminium.
- the top profile 3 is in this case configured as a shutter box with therein two end plates 6 suspending an axle 7 that carries the roller shutter 8. Internally in the shutter box or externally thereof a spring is provided acting on the axle 7 through a transmission (not shown). Further a lock acts on either the transmission or directly on the axle 7 and, when in an active position, prevents rotation of the axle 7.
- the lock is preferably coupled to a fuse and configured such that when the fuse melts, the lock disengages the transmission or axle 7.
- other release mechanisms for the lock can be provided.
- the bottom profile in this case comprises an inner cavity wherein an electric drive means, in particular an electric motor 9 such as a stepper motor or a geared DC motor, is provided.
- This electric motor 9 drives a winch axle 10 for winding and unwinding a cable 11.
- the cable 11 is on the one hand fixed to the winch axle 10 and on the other hand connected to the roller shutter 8, preferably a bottom portion thereof as shown in Fig. 3 .
- the upright guides 2 are configured as U-shaped guides bordering two opposed sides of the passage 5 and cooperate with two opposed edges 8b of the roller shutter 8 for guiding a movement thereof between an open and closed position.
- the roller shutter 8 is preferably manufactured of two superimposed sheets 12 & 13 of heat resistant material such as aluminium, with in between these layers 12 & 13 strips or pockets of intumescent material 14.
- Intumescent materials are materials that swell (expands) as a result of heat exposure, thus increasing in volume. More particular an intumescent material undergoes a chemical change when exposed to heat or flames, becoming viscous then forming expanding bubbles that harden into a dense, heat insulating multicellular char. Intumescent materials are well known in the field of smoke evacuation dampers and will not be discussed in further detail. Examples of intumescent materials can be found in US 4,273,879 .
- the thickness of the slats roller shutter 8, measured in a direction perpendicular to the plane of the superimposed sheets 12 & 13 at the location of an intumescent stroke or pocket is configured to fit in the U-shaped guides 2, but once the intumescent material has expanded, the thickness of the roller shutter 8 preferably increases to an extend wherein the roller shutter become blocked the U-shaped guides and a friction fit is established between the roller shutter 8 and the U-shaped guides 2, thereby immobilizing the roller shutter 8 in place.
- the cable 11 is preferably manufactured in steel or stainless steel. Depending on the dimensions of the smoke evacuation shutter and, in particular on the width W of the roller shutter 8, a number of parallel extending cables 11 can be used, each connected on the one hand to the winch axle 10 and on the other hand to the roller shutter.
- the roller shutter 8 In normal conditions, ie. no emergency or fire test, the roller shutter 8 is in a closed state shutting of the passage 5 in the frame 1.
- the spring is loaded and acts on the roller shutter axle 7 biasing the roller shutter 8 to an open position.
- the lock maintains the roller shutter 8 in its closed position against the force of the spring.
- This closed state of the roller shutter 8 with the spring loaded is also referred to as the armed state of the smoke evacuation shutter.
- the lock disengages the transmission or shutter axle 7 upon which the roller shutter starts moving towards an open position under impulse of the spring. This movement continuous until the roller shutter opens the passage 5 in the frame 1.
- the spring is preferably relatively strong for the dimensions and weight of the roller shutter, this opening of the roller shutter happens relatively fast.
- the opening of the roller shutter involves an unwinding of the cable 11.
- the electric motor is activated an and starts rewinding the cable 11 to a predetermined extend, such that the roller shutter is partially reclosed to an intermediate position not coinciding with either the open or the closed position.
- the smoke evacuation shutter can be rotated over 90° (or any other angle) such that the upright guides extend in a horizontal longitudinal direction.
- the present invention does not only concern a roller shutter, but also addresses fire dampers.
- the parts of a fire damper according to the invention are in general the same as the parts of the roller shutter described supra, the special organization of these parts will vary.
- the electric drive means are, in case of a fire damper, to be provided at the same side of the passage as the roller shutter.
