Fire protection sliding door

The innovation concerns a fire protection sliding door with at least one suspended by means of a sliding profile in a driving profile Thermal insulation layers formed sliding door leaf with wall and jj

ceiling-side labyrinth seal-like seal and with bottom guides.

To close fire compartment penetrations, fire protection gates are provided, which are indicated by suitable indicators in the event of a fire solved, close the opening in the fire protection wall. Included Such fire protection gates are often used as gates for the | Normally used. In addition to self-closing double doors are Sliding gates known, which are provided with a bucket drive, which ensures that they are in front of the penetration opening in the event of a fire

be pushed in the firewall. As a drive for this, reference is made to the weight drive, which is independent of external sources of power, the closing worried when a fire indicator indicates the outbreak of a fire in the fully open partially open position Fire reports. In order to be able to keep such sliding doors open in industrial halls, locks are also provided, which the Hold the sliding gate leaf in the open position and when a fire indicator is triggered, the sliding gate leaf is triggered Release closing, with closing itself from a drive is concerned - For the internal process are such Sliding gates are advantageous because there are no swivel areas for the door leaves, they open and close and are simple linear movements a sliding gate that can be adapted to meet specific requirements permitted. Traffic routes can be opened just as far as it corresponds to the operational requirements. These advantages the sliding gates are opposed to the fact that they must be adapted as a whole to the dimensions of the fire compartment penetration, with im generally the width of the gate is subject to greater variations than the height. Resulting from this adaptation to the dimensions consequential problems in the transport of the sliding gate leaf can be seen right up to the installation site.

Nier introduces the innovation on which the task is based, one Specify construction of a sliding gate wing, which avoids this Nachtei-Ie and in a simple manner an adaptation, in particular allows to the width, whereby transport and installation should be simplified and a simplified and economical production should be made possible.

According to the innovation, this object is achieved in that the sliding gate leaf is formed from a number of interconnected individual elements and end faces of the individual elements facing one another are provided with interlocking tongue and groove connections are, each of the individual elements with one preferably in the middle arranged undercarriage is provided. Through this training of the

- ¹ sliding gate leaf is achieved that a whole seala of sliding gate leaf widths is covered with one element width. The resulting sliding gate leaf width as an integer multiple of the width of the individual elements allows sufficient adaptation to any opening width in practice. The individual elements can be transported in a simple manner, since they can be stacked and, if need be, allow truck transport with consideration of any excess length. Even at the construction site, you can even use them

transport. The production is also significantly simplified, because only elements of one width are manufactured and series production is possible. The fire retardant properties of the These individual elements are assembled sliding gate flights ensured by the interlocking tongue and groove connections between the individual elements. It is irrelevant whether each element is provided with a groove on one side and a tongue on the other or whether there are elements that are on both sides are provided with tongues or grooves on both sides, the latter always being used alternately. 20th

A further development is given by the fact that the individual elements formed sliding gate leaf is divided into two parts, both of which consist of several Sliding gate leaves formed by individual elements form a bipedal one

! 25 sliding gate leaves can be locked with a tongue and groove connection is. Such two-leaf sliding gates are particularly useful

In a preferred embodiment, the joints between the ί 35 individual elements are sealed on at least one side with thermal insulation strips.

covers, according to a further suggestion which the joints between the individual elements covering thermal insulation strips are arranged in a sheet metal jacket. Finally, it is suggested that the Sheet metal jacket with each thermal insulation strip covering a joint an approximately U-shaped extension is provided, wherein the U-shaped extension can be clamped in a form-fitting manner with the tongue forming the groove of the tongue and groove connection. By covering the joints at least on one side with thermal insulation strips, one for each joint continuous thermal insulation strip is provided from top to bottom, every joint area is secured against undesired heat transfer. The double-sided arrangement of thermal insulation strips is special then of importance if it must be assumed that a possible source of fire can lie on either side of the fire compartment enclosure. The sheet metal provided for the thermal insulation strips jacket protects the thermal insulation strips from mechanical impact. This is especially important because the thermal insulation strips like many other thermal insulation materials, they usually consist of an impact-sensitive cement-bound material. The coat with Providing a U-shaped approach allows easy clamping of the Sheath on the tongue forming the groove of the groove part of an individual element. Here, too, it is irrelevant whether the individual element is equipped with a tongue and a groove or whether individual elements are used alternately with two tongues or two grooves become: In each case, each of the successive connections is fertilize covered with a thermal insulation strip.

A development is given that the lower ends of the Individual elements of each sliding gate leaf by means of a profile that runs along their lower edges and encompasses the underside edged and thus connected to one another, each of the individual elements having at least one fixed connection to the encompassing profile. It is also alleged that this is the underside encompassing profile protrudes at least on one side and than between zv / egg fixed guides running guide profile is formed.

Through this lower end the individual elements are attached to their

♦ · * · · '(IJ I Cji U ■ · · |

T 664-jS / if

Underside connected to each other; in addition, it becomes jamming The attached shock cover is prevented from slipping downwards. The one that protrudes to the side at right angles to the sliding gate leaf Cantilever interacts with guide profiles attached to the floor, which act as a continuous rail or as a short over the Rail sections distributed along the way of the fire protection sliding door could be. The few fixed connections of the profile encompassing the underside with the lower edge area of a each of the individual elements can easily be produced at the installation site, see above

IQ that this joining involves assembling the sliding gate leaf does not conflict with it on the spot.

A further development is given in that the individual elements of a sliding gate leaf are connected to one another at least at their upper ends by a connector bridging the joint. It is further proposed that each of these connectors is formed from angles arranged on the top near the end face of the individual elements and a screw bolt extending between these angles. Finally, it is proposed that the screw connection can be prestressed with a spring. In addition to the connection in the lower edge area, the connectors bridging the joints between the individual elements also create connections in the upper edge area, which improve the cohesion of the individual elements of each sliding gate leaf via the clamping of the tongue and groove connection. In a simple manner, these connectors are formed from angles arranged close to the joint, the free, protruding legs of which have bores through which a screw is pulled as a connecting bolt. Pre-tensioning the screw connection by means of a spring arranged between the nut and the angle leg as an abutment, regardless of whether it is a spring washer or a compression spring, prevents shocks from being transmitted by removing a rigid coupling and also makes the connections largely free of external influences such as temperature fluctuations . 35

A further development is given in that one of the end faces the individual elements are provided with at least two drop hooks distributed over the height and the other end face with almost corrosive

j ponding striking plates, so that two opposing

Front sides can be hooked together by means of the drop hooks. Additionally the case hooks a connection to the connections of the individual elements in the area of the upper and lower edges also ensured in the middle areas. It is advantageous to hook the case in the tongue of the tongue and groove connection Provide ι 10 and the corrosponding strike plates in the ground

their groove. This makes the case hooks easily accessible. Here, too, it is irrelevant whether the individual elements are one-sided with a Tongues or liner grooves are provided or whether individual elements have tongues and individual elements with grooves for the construction of the sliding gate leaf be used alternately. In any case, a tongue always pushes into a groove so that the drop hook and strike plate interact with one another can. It goes without saying that both the drop hook ι and the locking plates for better transmission

jj of the forces with a possibly inside each of the individual

elements existing reinforcement frame can be connected. When the individual elements are joined together, the inclined surfaces slide the FaI! hook on the lower edges of the openings in the strike plate on, the case hook is raised and it engages when it is brought together

* two single elements. The so interlocked individual elements

25 ments can now be in the area of their upper and / or lower edges

are further connected to each other.

For a fire protection sliding door with two sliding door leaves suggested that the two sliding gate leaves in the area of the disclose shock having a shock absorbing device. About that It is also proposed that the shock absorbing device from one there is a shock absorber attached to a sliding gate leaf, the pusher attached to the other sliding gate leaf with one Opposite angle! cooperates. By the arrangement of the shock absorber 35 the sliding gate

-.J - .... T 664-jS / if

Blades converted kinetic energy absorbed by the shock absorber so that the sliding gate leaves slide dampened into their end position. This is achieved in a simple manner by a shock absorber fastened close to the exposed joint, while the second sliding door leaf in the corrosive position, e.g. has an angle as an abutment for the shock absorber tappet.

For easy operation of a sliding gate leaf according to the innovation it is proposed that near a vertical edge of a terminal Single element a grip shell is provided. With the help of this shell grip, a point of attack is given over which the forces required to open or close the gate can be transmitted to the sliding gate. It goes without saying that the shell handle can also be connected to a locking device for one or both sliding gate leaves, so that there is no unintentional opening and opening only after unlocking can be done.

Finally, a further development is proposed in which the chassis the individual elements via resilient links with the individual element are connected. It is also proposed that each of the resilient Links with a guided in a sleeve, as a compression spring formed coil spring is provided, wherein the connecting bolt of the chassis with play through an opening in a top plate serving as an upper abutment for the coil spring is and with a nut that can be moved up and down in the sleeve al.-adjusting screw is screwed. This suspension of the chassis adjustability is created in a simple manner, co that the depth of immersion of the tongue * · in the groove of the adjacent individual element is easily adjustable over the entire height. All individual elements can be adjusted using this simple type of adjustability Bring it into a vertical position and align it parallel. The suspension also helps with bumps in the runway or deviations to overcome from the horizontal.

Thermal insulation strips 20 covered. The sliding gate leaf is along the |

- to the side shown interrupted - moving track 4 = bar. It can thus be brought from the closed representation, as shown, to an open position. In the open position It becomes the corresponding end position through the interaction of a

releasable holding member 8 with this holding member facing Side of the sliding gate leaf locked. To ensure the function of the fire protection sliding gate and to lock the To ensure fire compartment penetration, this triggering by means of appropriate detectors, e.g. ionization smoke detectors, infrared fire alarms, temperature sensors, detonators or the like. A weight drive with a weight 5 guided in a guide 5.1 acts via a train 5.2 on the sliding gate leaf 10 and closes it automatically after unlocking. Around the sliding gate leaf 10 to be able to open without difficulty is a handle shell 12.3 provided near the vertical outer edge.

FIG. 2 shows an analogous view; however, a sliding gate with two sliding gate leaves 10.1 and 10.2 is shown here, the | to open (and thus also to close) in opposite directions Direction can be shifted. It is not necessary that both sliding gate leaves 10.1 and 10.2 open and close evenly. Ben, there can also be other aperture ratios. Each the sliding gate leaves 10.1 and 10.2 are made up of a number composed of individual elements 11 and each of the individual elemen-] te 11 is slidable with one in the profile of the running rail 4 Undercarriage (Fig. 1). The running rail 4 itself is in the Dar position canceled; it is at least the width of the Sliding gate leaf 10.1 or 10.2 to the outside, with it without The meaning is whether the sliding gate leaves 10.1 or 10.2 are the same Have width. In certain local conditions it can even be advantageous to have one of the sliding gate leaves narrow to make others wider accordingly, in order to be able to open up traffic routes of different widths. The individual elements are hooked together in the area of the joints, a case hook 16 is through a corresponding outbreak is shown, the others are indicated by double lines. Each case hook is in a pocket 15 movable and engages with its hook-shaped end in one

To open the sliding gates, grips η 12.3 provided at a suitable grip height. Here, too, the sliding gate leaves 10.1 and 10.2 are driven via drive elements - not shown in detail - which are connected to each other via the trains 5.2 the other side arranged sliding gate are connected so that the sliding gate leaves lö.l and 10.2 under the action of Forces of the drives against each other move into the closed position.

Figures 3 and 4 show cross sections through a sliding gate a sliding gate leaf 10 (Fig.3) or a sliding gate with two Sliding gate leaves 10.1 and 10.2 (Fig. 4). The one to be locked Opening 1 is located in a fire protection wall 1.1, which encloses a fire compartment. The sliding gate leaf 10 closes this opening 1. In FIG. 4, the two sliding gate leaves 10.1 and 10..2 partially withdrawn so that an opening in the middle is present, which reveals the guide pieces 9 of the bodensei ti gene rail. The sliding gate leaves 10 or 10.1 and 10.2 are composed of individual elements 11; the joints between the individual elements are covered on both sides with thermal insulation strips 20. The wall connection is made in a known manner by labyrinth-dich similar arrangements 2, with wall side fastened and door strips attached on the leaf side interlock and thus form the conclusion. The central lock of the sliding gate with two sliding gate leaves 10.1 and 10.2 is designed in the usual way of a tongue and groove connection, the cover with thermal insulation afford 20 is provided.
