Description

The The present invention relates to a wall element for a movable fire barrier, wherein the wall element is a support structure comprising at least two largely parallel arranged horizontal profiles and at least two largely parallel arranged vertical profiles that are connected together in the corner areas are, and wherein the wall element at least two plate-shaped Fire protection elements comprising the support structure Cover completely at the front and back.

The The invention further relates to a movable fire protection partition from at least two next to each other and / or one above the other arranged wall elements is constructed.

wall elements for a movable fire protection partition or movable Fire safety partitions consisting of such wall elements are constructed, are known in principle from the prior art.

So a mobile fire-protection partition is offered on the market, which is composed of individual, interconnected elements. Each of the elements is a square or rectangular Steel tube frame built. The frame construction is on each Front and back covered with refractory plasterboard, which are attached to the frame construction. The cavity inside The wall elements are filled with mineral wool. The single ones Wall elements are installed on a ceiling rail suspended laterally displaceable. In the floor and ceiling area can from the wall elements by means of an internal adjustment a Sealing lip are extended. The juxtaposed plate elements grip in the closed state of the partition by groove-spring-like Side edges into each other and form in this way a superficial smooth partition.

in the Fire, it can be in this known partition or for whose construction wall elements prove to be problematic that With increasing heat, the fire wall partition strong bends towards the fire side. This one due to the different temperatures on the fire side and the side facing away from the fire and known effect can lead to leaks, because the individual elements are no longer sufficient due to the strong bending seal against each other. Even bigger problems can occur when such individual elements Fire protection partition walls with large wall heights to be built, for example, from 4 meters height or even clear about it. Then it would be in the In case of fire, bend the dividing wall so strongly in the direction of the heat source, that leaks can occur after a short time - leaks, by the dangerous flue gases, as well as heat and also flames to get to the other side. The protective effect would therefore no longer exist. For this reason, so far the possible height of movable fire-resistant partitions heavily limited.

The Object of the present invention will now be seen in a movable fire protection partition or single wall elements for construction to create such a fire barrier, with which partitions high altitude can be built without that in case of fire, the fire protection properties fail comes. For this purpose, the to be developed movable fire protection partitions can reach heights of well over 4 meters, preferably more than 6 meters.

These The object is surprisingly achieved by that instead of a support structure of steel pipes in the wall elements a support structure is used, where at least the vertical steel tubes are replaced by wooden profiles become.

These Solution is surprising in at least two ways. First, because wood is combustible as opposed to steel Material an unusual building material for the Fire protection represents. The other reason is that at for the construction of very high fire protection elements due to the expected special static stress on the load-bearing parts, for these usually on more stable materials such as steel or aluminum would be used.

One The first object of the present invention is therefore in a wall element for a movable fire protection partition, the wall element having a support structure, comprising at least two largely horizontally arranged horizontal ' Profiles and at least two largely parallel arranged vertical Profiles that are connected to each other in the corners, and wherein the wall element at least two plate-shaped Fire protection elements comprising the support structure Cover completely at the front and back and wherein the wall element is characterized in that the vertical Profiles of the support structure made of wood.

The support structure of vertical and horizontal profiles thus has approximately a rectangular or square shape. In the present invention, it is important for fire safety reasons, that especially the wood profiles are protected by the fire protection elements substantially completely against the action of flame by the complete covering.

at Investigations leading to the present invention have turned out that the strong bending out of As far as possible known in the art fire protection partitions from the steel frame construction itself and not for example, from the fire protection boards or other components used. One possible explanation for this is that the one-sided heating of the steel frame from the fire side Apparently this causes the metal on this side expands more strongly than on the opposite Page, despite the good heat conduction properties of steel. Due to the different degrees of pronounced Expansion of the tubular steel frame then bends in the direction of Exposed to fire.

Of the The present invention is based on the finding that by the replacement of vertical steel pipes by wooden profiles on the one hand the generally considered disadvantageous bending in case of fire strong can be reduced and that on the other hand, wood quite as Material also suitable for fire protection applications and even in case of fire has sufficient stability that in this way movable fire walls with large Heights of 4 meters and more can be built.

The movable fire walls according to the invention can reach heights of, for example, more than 5 meters, more than 6 meters or even 7 meters or more and thereby the fire protection requirements DIN EN 1364-1 suffice. The mobile fire protection partitions, which are made from the wall elements according to the invention and have a height of, for example, 6 meters, follow a fire protection test DIN EN 1364 Part 2 stood for more than 1 hour.

One further advantage of the wall elements according to the invention is that these are prefabricated already modular can. The support structure with vertical wood profiles allows manufacturing technology a higher flexibility as with steel profiles, usually in the corner areas be welded together. In contrast, let screw the wood profiles, creating the support structure also easier to disassemble again, for example to shorten the vertical wood profiles and so in relation to adjust to the height. This is essential with steel pipes connected higher effort.

A preferred embodiment of the invention Wall element is characterized in that the horizontal profiles the support structure also made of wood. This is particularly advantageous because in this way the bending of the Wall element and thus a movable fire wall partition in which this element is installed, even further reduced in case of fire can be.

A Further development of the wall element according to the invention provides that the wall element on at least one vertical side a concave (groove-like conical) or convex (feathery conical) face having. This is particularly advantageous because in this way the individual wall elements during assembly to a movable fire wall partition can be better fixed against each other.

These concave or convex end face may be more preferred Be equipped with a magnetic rail. To this Way snap when installing the wall elements in a movable partition when closing this wall the individual elements more exactly into each other. In addition, the magnetic stripes hold the individual wall elements close together, which increases the risk of passage reduces smoke in case of fire. The partition wall is characterized but also closer to drafts or noise.

To a further preferred embodiment of the invention Wall element, the wall element at its upper end side a connecting part on, with which the wall element displaceable and possibly to the longitudinal axis rotatable on a frame, a ceiling track rail or a building part is attachable. In this way can such wall elements in a simple way for use the construction of a movable partition and can when opening the partition to save space on one side of the opening, the is closed by the partition wall, be moved. Prefers the connecting part is connected to a scroll, which in a Ceiling track is running.

According to the invention it is preferred if the wall element at its lower and / or upper End face has a retractable sealing strip or sealing lip. In this way, when installing such a wall element in a movable fire wall when closing the wall this wall element can be mechanically fixed to the floor or the ceiling and at the same time ensuring the smoke-tightness in this way become. The retractable sealing strip, for example, over one inside the wall element or fire protection partition located adjusting mechanism via a crank drive be moved out.

Especially preferred is a wall element according to the invention in which the plate-shaped fire protection elements visible Almost completely absorb light and heat radiation and / or reflect. Such fire protection elements are, for example from mineral, in particular silicate materials Pressing with or without the use of additional binders manufactured and characterized by very good fire protection properties at relatively low weight.

One Another object of the present invention is in a movable fire protection partition, the at least two next to each other and / or one above the other arranged wall elements according to the invention comprises. Such a fire barrier has the advantage that they themselves in comparison to the previously known movable fire-resistant partitions bend much less in the event of fire and therefore also as very high mobile fire protection partitions the fire protection regulations in terms of heat insulation and smoke tightness can.

A preferred embodiment of the invention movable fire wall is characterized by the fact that the vertical side surfaces of the wall elements at the facing each other Sides by nut-spring-like design with conical contact surfaces in space-separating position frictionally and sealingly mesh. This allows a more accurate positioning the individual elements when closing the wall.

there It has proved to be particularly advantageous if this conical contact surfaces each equipped with magnetic rails are and the wall elements attract each other in this way. As a result, the movable fire barrier is better against the Passage of smoke secured but also against normal Air passage, reducing energy costs for heating or cooling the interior can be saved.

A Development of the movable according to the invention Fire protection partition provides that the horizontal side surfaces of stacked wall elements to each other assigning sides by means of a tongue and groove joint and optionally a screw connection are connected. In this way can, especially in combination with the optional additional screw connection, the individual wall elements very be precisely fixed to each other, so even in case of fire no smoke or flames can pass between the elements. Two or more generally several wall elements fixed on each other then form a single separator, the whole as an example a composite element about the longitudinal axis rotatable with a Roller unit running in a ceiling track rail and in this way the entire separating element is conveniently rotated and can be moved laterally.

A inventive fire protection partition exists in the simplest case one, preferably several, side by side in the ceiling track rail mounted separating elements, so the segments a movable fire protection partition according to the invention form. To close the fire wall, the Dividers pushed together and fixed together.

To a further preferred embodiment of the invention movable fire wall have the respective top wall elements the fire protection partition at its upper end in each case at least a connecting part with which the wall elements slidably and optionally rotatable about the longitudinal axis on a frame or a building part are attached. In this way, the fire wall can be partition disassemble without much effort and the individual elements push aside. Just as easily manages the reconstruction or the Closing the fire protection partition.

A furthermore preferred embodiment of the invention movable fire barrier is characterized in that the respective lower wall elements at their lower end side respectively have at least one retractable sealing strip or sealing lip. In this way, the fire protection partition on its lower side by moving the sealing strip to the floor, for example of the building by the resulting contact pressure on the one hand be fixed and in this way at the same time a seal towards the passage of smoke or even drafts and make noise.

To the same purpose, it may be advantageous if in the inventive movable fire wall separating the upper wall elements at least one retractable sealing strip at its upper end side exhibit. These sealing strips can therefore at the top and / or bottom edge of the fire-protection partition, or of the individual separating elements the fire protection partition are provided.

A further development of the movable fire protection partition according to the invention is characterized in that at least one of the outer wall elements of the fire protection partition has on its outer vertical side surface a nut- or spring-like design with conical contact surface, which with a corresponding thereto lateral conical contact surface of a festste Henden associated end element in space-separating position frictionally and sealingly engages each other. In this way, the movable fire protection partition can be better stabilized on one or two fixed to the walls end elements. For this purpose, the respective outer wall element or separating element of the movable fire protection partition according to the invention has a correspondingly shaped concave or convex conical contact surface. The conical contact surfaces ensure better sealing of the fire-protection partition against smoke, drafts or even noise. Again, the respective concave or convex end faces of outer wall elements and end elements can be equipped with magnetic rails.
