Definitions

  • the present invention relates to a side guide for a fire protection closure, which has at least one guide rail, wherein the side guide enables a fire protection closure to be moved along the guide rail.
  • the side guide is sufficiently resistant, in particular in the event of a full-scale fire.
  • the present invention also relates to a fire protection closure guided by at least one such side guide.
  • a fire protection curtain of a fire protection closure guided on two sides by such a side guide can be deployed over a large area.
  • Guide elements located on one side of the curtain support the guidance of the curtain.
  • side guides for closures can have special design features in addition to the guidance aspect, which are usually derived from the special requirements placed on the closures. Therefore, different types of closures usually also have specifically designed side guides.
  • the following publications provide some examples of such side guides and closures.
  • a guide rail of a roller shutter guide described in the publication includes an inner rail, which is typically made of plastic or metal as a rod extrusion. A side edge of a roller shutter curtain is guided in a groove of such a guide rail. For reasons of appearance, an outer rail made of wood can surround such an inner rail.
  • the US 2011/0 061 822 A1 (Applicant: Storm Solutions, Inc.; Disclosure date: March 17, 2011 ) proposes a flexible curtain that can be threaded into retention channels on both sides and can be rolled up compactly using a mechanism to protect building openings during a storm.
  • a blackout curtain is described in the patent application FR 1 260 823 A (Applicant: M. Herbert Reppert; Filing date: April 8, 1960 ), the side slides of which have two opposing wooden strips inside, which are intended for the attachment of cover strips.
  • curtains designed to provide protection against storms are, for example, from the patent application US 2006/ 0 151 132 A1 (Applicant: Augustus Scalfani, et al.; Filing date: January 13, 2006 ), whereby such a curtain is guided in a slot in a side frame.
  • US 2011/ 0 061 822 A1 Applicant: Storm Solutions, Inc.; Filing date: September 15, 2010
  • a curtain with sewn-in loops on its edge can be guided over a wooden hem rod.
  • closures and the guides provided for their side edges have in common is that they are only intended to improve protection against environmental influences such as light, wind and weather.
  • a side guide for a roll-up protective curtain is known from the utility model DE 299 22 593 U1 (Applicant: Stöbich Brandschutz GmbH & Co. KG; filing date: 23.12.1999 ).
  • the protective curtain is designed to prevent the spread of fire and smoke by creating a dividing surface on the side guide to divide the room, at least temporarily in the event of a fire.
  • forces act across the curtain surface, which can lead to obstructions when winding up or unwinding the curtain.
  • DE 299 22 593 U1 It is suggested that the curtain sides be held with a side seam.
  • the side guide comprises a rod element that is arranged on the building side and over which the hem of the curtain is pulled.
  • the rod element can also be held to the guide profile with a support element, whereby a layer of the hem should be able to be inserted between the support element and the rod element.
  • the hem must be widened when pulled onto the rod element, which is why additional forces must be applied when unrolling the protective curtain, which can slow down the unrolling process. A possible risk of jams when unrolling the curtain cannot be completely ruled out.
  • a slightly different concept of a lateral guide is described in the utility model DE 20 2004 018 977 U1 (Owner: Stöbich Brandtik GmbH & Co. KG; Registration date: 08.12.2004 ), with particular emphasis on improving the sealing arrangement for a fire or smoke curtain.
  • the guide rails for the curtain are also made up of several parts, with fastening elements such as in Figure 3 the DE 20 2004 018 977 U1 shown, protrude into an inner area in which the rollers or sliding elements are located.
  • the curtain should run through an area with so-called "zig-zag"-shaped projections and depressions, which, like on an associated curtain box, are probably formed by metal sheets.
  • WO 2016/003 366 A1 (Applicant: Gliderol Doors (S) Pte. Ltd.; Publication date: 07.01.2016 ) is an insulated fire barrier that is to be composed of several plates. The plates are to be stacked next to each other when the barrier is open and arranged one above the other when closed by inserting them into a side guide.
  • a guide rail for a smoke and/or fire curtain in accordance with DE 20 2015 100 372 U1 should be made of a metal profile, possibly with a filling of a cooling material.
  • the guide rail should have a guide profile strip.
  • a pull-out protection device should prevent the edge area of a smoke and/or fire protection curtain from being pulled out.
  • An elastic element should provide pre-tensioning of the curtain.
  • the DE 20 2010 009 538 U1 (Owner: Hoefnagels Projectzonwering BV; Publication date in the Patent Gazette: 02.12.2010 ) describes a fire-retardant roller blind that has a double-walled curtain made of a fire-resistant material.
  • a thermally expandable material is to be arranged between the walls of the curtain.
  • the walls are to be constructed from parallel panels that extend across the width of the curtain and are sewn together, with an inner strip that is rigidly connected to the opposite wall.
  • the roller blind is to be guided by extensions or coupling elements through a hollow casing on the side that extends over the height of a room and is to be covered with a thermally insulating panel.
  • the product standard DIN FprEN 16034:2014 specifies performance characteristics for fire and/or smoke protection for doors, gates and windows.
  • the standard DIN EN 1634-1:2014 deals specifically with fire resistance tests and DIN EN 1634-3:2014 with the testing of smoke protection closures. The results of the tests are incorporated into classifications that are laid down in the standard DIN EN 13501-2:2003.
  • the letter “E” therefore indicates Requirements for room closure, with the letter “I” requirements with regard to thermal insulation and with the letter "W” requirements with regard to radiation limitation, which include classification times which are to be specified in minutes and which must therefore be observed over specified periods of time.
  • Laterally movable fire protection closures require reliable side guides that comply with the relevant fire protection regulations, with interested parties often expressing a desire for production to be as environmentally friendly as possible. Preferably, production should be cost-effective using common processes.
  • Other aspects include making the installation of fire protection closures as easy as possible and improving operational safety, particularly for long-term operation of fire protection closures.
  • a fire protection closure In many buildings, especially in old buildings, there are areas where people stay and installations for which special protective measures must be taken in the event of a fire or smoke spreading. In order to limit the risk of a fire in the building, fire protection closures are installed that must be activated in the event of a fire.
  • a fire protection closure separates two room areas from each other.
  • a side guide is required for a sealing connection between the closure and a part of the building, such as a wall or a passage frame.
  • the side guide can comprise several components. The side guide makes it easier to move the fire protection closure if a room separation is to be created in the shortest possible time.
  • the fire protection closure is held in a ceiling area or a lintel area so that the closure can be extended to the floor with the help of gravity.
  • Side guides extend in a vertical direction. Side guides can also be used horizontally, for example if a ceiling opening or a floor opening is to be closed.
  • the fire protection closure can be wound up in a winding box as a fire curtain that can be quickly pulled out in the event of a fire.
  • Both the materials of the fire protection closure and the materials of the side guide must have sufficient fire resistance, or in other words, at least be flame-retardant.
  • Side guides should withstand fire for at least 30 minutes. The side guide must ensure that the fire protection closure remains in position after it has been closed and that the protective effect is not lost prematurely.
  • Band protection side guides can also be used for closures such as rolling, lifting, sectional, lifting and sliding doors specified for fire protection.
  • a side guide comprises at least one guide rail.
  • the guide rail is a component of the side guide.
  • the guide rail is preferably located on a side area of the fire protection closure. At least one edge, preferably two edges, of the fire protection closure can be enclosed by the side guide. The enclosure can be caused by the closure entering the side guide.
  • a fire protection closure can be moved along the side guide.
  • a predominantly lateral movement is possible.
  • a lateral movement is a movement that is limited by the guide rail.
  • a first direction of movement can be more limited than a second direction of movement.
  • At least one direction of movement is a longitudinal direction of movement. It is possible for the fire protection closure to cling to the guide rail at least in part during movement.
  • Side guides are preferably used in pairs, in particular as parallel guides, with the fire protection closure extending between the side guides. It can also be said that the fire protection closure can be extended in the side guides.

  • the side guide comprises a guide channel.
  • the guide channel is a part, such as an area, of the guide rail.
  • the guide channel is preferably located in the guide rail.
  • the guide rail delimits the guide channel.
  • Several guide channel sides can be assigned to the guide channel.

  • the guide channel can be designed to be mirror-symmetrical with respect to a mirror plane that can be laid structurally through the guide channel.
  • the guide rail is made entirely of wood.
  • All components of the guide rail that make up the guide channel are made of wood. Due to the low heat conduction, a guide channel with at least one side made of wood is advantageous.
  • the guide channel is made entirely of wood. A wood that is flame-retardant is particularly suitable.
  • wood is basically a combustible material
  • experience has shown that wood must be exposed to an open flame for a relatively long time before it can start to burn.
  • the desired combustion is therefore usually accelerated by chipping wood.
  • surface-treated and thus smoothed wood is used as a guide rail.
  • the treated surface is particularly chip- and splinter-free.
  • the combustion properties of types of wood are known or can be calculated. On the basis of the calculations, a very effective construction geometry can be determined that offers a sufficiently long durability against combustion. It is even possible to reduce the use of materials to a minimum on the basis of the calculations.
  • Wood has many advantageous properties for fire protection that are generally not considered due to the fact that wood is generally combustible.
  • wood is a very good thermal insulator. In the event of a fire, wood remains largely free of distortion. If a guide rail is installed on a building, hardly any stresses from the fire protection seal are transferred to the building in the event of a fire. The building's statics are hardly affected by the subsequent installation of wooden side guides. Guide rails made of wood can be tested and classified for their fire resistance using standardized test procedures. In contrast to steel, wood is an easy-to-work material that dulls conventional processing tools relatively slowly. Wood is also relatively light. It is possible to use wood for fire protection without additional cladding or coatings.
  • wood Due to the good workability of wood, the energy required to produce guide rails is low. As a renewable natural product, wood is also completely biodegradable, recyclable and does not cause any disposal problems, e.g. when a building is demolished. Guide rails made of wood can be manufactured in a very environmentally friendly way. In addition, wood is often used in residential areas in particular because of its optical properties and the feeling of space. Wood is a preferred building material, particularly for listed old buildings that are to be subsequently upgraded to improve fire protection. in order to use as few materials as possible that were not yet available at the time when an old building was constructed.
  • the guide channel is limited on at least four sides.
  • the guide channel has a clear cross-section and has a passage to a free interior area on at least one side.
  • the side extends continuously, in particular between the inlet end and the end end of the guide channel.
  • the term four-sided limitation can also be understood to mean that, viewed at the cross-section, there is a limitation in four directions of space, whereby the limitation, at least in one spatial direction, is not a final limitation.
  • the guide channel serves to accommodate at least one guide element, such as a sequence of guide elements.
  • Guide elements are arranged in such a way that they can be inserted into the guide channel.
  • the guide elements are connected to the fire protection closure, in particular to an edge region of the fire protection closure.

  • the guide element can be connected to the fire protection closure, in particular to the fire protection curtain, via a connecting means.
  • a fire curtain can be designed as a fire protection curtain. Guided on the sides, a fire curtain can be deployed over a large area. In other words, it can also be said that a fire curtain of a fire protection closure guided on two sides with a side guide can be deployed over a large area. The deployment can be carried out, for example, by the effect of gravity and/or a drive unit.
  • a fire curtain can be arranged on a winding device before deployment. It is also possible for a fire curtain to be gathered up, e.g. stored in a box, for deployment. For a fire protection closure, several fire curtains and side guides can be arranged next to one another.

  • the guide elements are located on at least one side of the fire curtain.
  • the guide rail preferably has several inner surfaces that adjoin one another.
  • the guide rail can also be described as a hollow body-like structure.
  • the similarity is that, in contrast to a real hollow body, a surface line of the body does not enclose a hollow space but runs like a groove.
  • an inner surface offers a surface along which the guide element or elements can be moved.
  • Fastening elements such as screws, nails, bolts or anchors do not extend into the free space of the guide channel. Fastening elements in the guide channel could hinder movement of the guide elements or even damage the guide elements.
  • the guide channel is continuous over the length of the guide rail.
  • a guide opening is formed along the guide rail. The guide channel opens into an outer area at the guide opening.
  • the guide opening is a through-opening for the fire protection closure.
