Doors with swing hinges used, e.g. B. of so-called T30 doors. The door panels are for modified the use as a sliding door leaf. However, it becomes essential constructive elements and materials of the proven fire protection constructions used. The door leaves can be made of wood, metal, composite, glass in so-called G or F version or a combination thereof. To the Door leaves can be used for intumizing materials over the entire scope Sealing must be attached. It is in the event of fire under heat foaming materials or similar volume-increasing materials. Preferably, the door edges are additionally stair-shaped at the sealing edges Designs, similar to those formed with overlapping revolving doors to get a tight seal in the closed position. The colliding Wing edges are preferably designed to complement each other. Correspondingly, the end edges on the wall or frame side be designed so that in the closed position of the door leaves a tight seal is guaranteed. Are preferably in the area in the closed position Edges intumescent materials provided.

The sliding door leaves 1, 2 are mounted on top rollers 3 in a fixed position Run pipe 4 out. The rollers 3 are mounted in roller carriages 13, which with the sliding sashes 1 and 2 are connected via suspension screws. By doing In the exemplary embodiment in FIG. 1, each wing 1, 2 carries two roller carriages 13. The structure of the roller carriage 13 and the basic structure of the running tube 4 corresponds to DE 36 02 440 A1. The castors are either completely made of metal or made of metal with plastic treads. Alternatively, you can consist of other heat-resistant materials.

A DC electric motor 5 is used to drive the sliding leaves 1, 2 provided with electronic control device 50. The electrical Feed lines, such as cables, etc., the motor 5 and the control device 50 can have additional heat protection, such as by appropriate heat and fire-resistant formwork.

All drive units are on all sides above the running tube 4 enclosed smoke-tight encapsulated receiving space 6 installed. Room 6 is formed in a so-called drive case 60, which extends from the upper edge the sliding sash 1, 2 extends to the ceiling 61 and outwards on the Front and back are covered by vertical wall elements 7, 8. The front wall element 7 is a sheet metal body with a rectangular cross section, the rear wall element 8 a downwardly angled metal panel. Up and below the room 6 is over sheets as well as plates and profile angles limited, which are attached to flanges of the running tube 4. The room is on the front side 6 limited by front wall elements. Both the drive case 60 and the wall elements 7, 8 are heat and fire resistant, for example by appropriate coatings or cladding applied inside or outside. It can commercially available fire protection materials such as bromate, Fermazell, Ri-Gips z. B. as Fairings are used. Alternatively, at least the External walls of the drive case 60 and the wall elements 7, 8 themselves made of these Materials exist. Foaming foils can also be used for Fire protection must be applied.

The DC electric motor 5 with the electronic control device 50 and the other units of the drive are on a common Mounting flange 51 mounted. The flange 51 is on the top of the Running tube 4 and is clamped there. For this purpose, the runner 4 has a upper horizontal flange 41 on the front and rear of the Cantilevered tube and a horizontal one to clamp the drive unit Has groove 42. The mounting flange 51 resting on the flange 41 engages with a complementary foot 52 in the groove 42. The clamp connection is obtained via vertical clamping screws in the area of foot 52 and groove 42 intervention.

The motor 5 drives a drive belt-like element 55, which on two guide rollers 56, 57 is arranged all around. The element 55 can be a toothed belt be made of heat-resistant material. Preferably a steel cable, e.g. B. Bowden cable used. But it can also be a metal band or the like be used. For driving connection of the sliding sash 1, 2 with the drive belt-like Element 55 are essentially C-shaped drivers 58, 59 intended. The driver 58 is with its upper leg with the upper Run of the belt 55 and with its lower leg with the upper edge of the Sliding wing 2 firmly connected. The driver 59 is in a corresponding manner the lower run of the belt 55 and with the upper edge of the sliding sash 1 connected. This means that wings 1, 2 are only in opposite directions Directions can be moved simultaneously. When the element 55 rotates The sliding sashes turn clockwise, when turning counterclockwise Open.

The deflection roller 56 sits directly on the in the illustrated embodiment Output shaft 5a of the electric motor 5. The deflection roller 57 is on a separate one Bearing bracket 57a mounted in the same way as the rest Drive units on the horizontal flange 41 of the running rail housing 4 is arranged and attached. However, the pedestal 57a is not on the Mounting flange 51 of the drive unit attached, but separately via a corresponding own shorter mounting flange attached.

The runner 4 with its molded flanges is designed as a hollow chamber profile. The hollow chamber forms the box-shaped running tube in which the carriage are led.

It has a longitudinal slot on the underside to allow the suspension screws to pass through, via which the sliding sash 1, 2 are suspended on the carriage. The formed on the top of the tube horizontal flange 41 is on the Front angled upwards and vertically angled downwards at the back. On an L-shaped angle 42 is attached to the upward-pointing leg 410, whose upper leg 42o horizontally at a distance above the drive units is arranged pointing to the back. The top of this leg is horizontal plate 43 screwed. It is cantilevered on the leg 42o on.

The downward leg 41u of the horizontal flange 41 ends vertically at about the same height as the bottom edge of the box-shaped Overflow pipe. On the leg 41u, a vertical plate 44 is screwed, which with Your lower horizontal edge is at the same height as the lower horizontal Edges of covers 7 and 8. At the lower edge of plate 44 is an L-shaped one Bolted profile 45, the horizontal lower leg 45u to Cover 8 is directed and with which the lower horizontal cover plate 46th is screwed. This sheet 46 lies on the leg 45u and on the lower one angled edge of the cover 8. The room previously described 6, which all drive units, d. H. Drive motor 5, control unit 50, Driving belt 55, pulleys 56, 57, etc., is limited by following walls: front and rear covers 7, 8, upper and lower Cover plates 43, 46 as well as flange 41, plate 44 and angle 42, 45.

To reach through the driver 12 is a horizontal in the vertical plate 44 Longitudinal slot 44s formed, which extends over the entire path of the driver 58, 59 extends. This slot forms the only opening of the box-shaped Room 6, which houses all drive units. The slot is smoke-tight sealed, for example by intumizing at the slit edges Materials are applied.

In the illustrated embodiment, the running tube 6 forms the load-bearing one Element of the facility. The running rail 6 can be designed as a self-supporting carrier his. However, a separate self-supporting support can also be provided which the runner 4 is attached. Alternatively, the wall elements 7 and / or 8 can be designed as load-bearing walls to which the running tube 4 is attached is.

In the embodiment shown in Fig. 3 is different from that Embodiment in FIGS. 1 and 2, the drive on a vertical wall 70th attached. It is instead of a box-shaped running tube one to one side open C-shaped tread 400 used, which has a lower tread 401 and has an upper tread 402 on which the lower supporting rollers 301 or the upper support rollers 302 run. The rollers are like that previous embodiment of heat-resistant material.

Otherwise, the drive in Fig. 3 has corresponding drive units as in the 1 and 2, namely a drive motor 5, one not shown in Fig. 3 Control device and a transmission belt-like transmission device between the output side of the engine and the sliding sashes.

All drive units including the drive with the rollers and the Running rails are arranged in a drive case 60. The drive case 60 is in same way as in the embodiment described above heat and fire resistant as well as smoke-tight, e.g. B. with a heat-resistant Fairing 60a and intumizing seals 60d.

As can be seen in FIG. 3, in addition to the sliding leaves 1, 2 there are also fixed field leaves 101 and 102 are provided, which are fixed in a conventional manner on the Track 400 or can be attached to the wall 70.

In modified embodiments, the sliding door systems can also only be designed as smoke protection closures. This means that only the measures are necessary that a smoke-tight in the closed position of the door Form conclusion. This can automatically move seals or intumizing seals 60d.

There is a significant advantage in the exemplary embodiments described in that a conventional sliding door system can be used, the through special measures as fire protection and / or smoke protection is modified. Self-supporting constructions with self-supporting can also be used Carriers, possibly also with self-supporting running rails, with all transitions between the building wall and the sliding sashes in particular in the area of the drive case 60 fire-proof or smoke-proof be designed.

It can also be used automatically moving seals that over corresponding contacts are controllable, preferably by contacts to the Sliding sashes or corresponding fixed contacts or in the drive case Arranged contacts that automatically in the closed position of the door in the sealing position be moved. You can also be switched so that they are only in the Fire trap can be moved to the active position.

The fire protection sliding door system in Fig. 4 is mounted in a facade construction, specifically in a mullion-transom construction. This consists of vertical beams, so-called posts, and horizontal beams, so-called bars. The drive unit 60 is fastened to the bolt 81, in which it is screwed there to the drive, specifically to the running rail 4. The sliding leaves 1, 2 are guided in the drive 4. The drive unit, which has the drive 4 and an electric drive motor and control devices, forms a composite cuboid body 60 which has a particularly low overall height. This vertical height corresponds to that of the bolt 81. In the exemplary embodiment shown, the drive unit is 7 cm and the bolt is 6 cm high.
The facade has large glass panes 82 which are clamped between the posts and transoms. The sliding panels 1, 2 consist of glass panes 91 with a profile frame 92.

The posts, the bars 81 and the frame 92 of the sliding sash 1, 2 are each trained as a profile. These are hollow profiles into which insulators 100 are inserted to obtain a fire-retardant effect. With the isolators it is a heat-resistant profile material. It can be conventional Profiles, e.g. Aluminum profiles for the mullions, transoms and sash frames can be used as they are conventionally without insulators for facades and Door frames can be used. Profiles can also preferably be used that are used in fire protection revolving door closings.

The vertical door level of the sliding sash is opposite the vertical Facade level in the horizontal direction inside or outside the building offset by the offset 99. This results from the fact that the drive 4 on the Inside of the latch 81 is arranged. One is in the door opening area Profile opening 95 surrounding the door opening area on three sides. This Profile construction has a horizontal upper profile part and two lateral vertical ones Profile parts. The top of the upper horizontal profile part is at the bottom the bolt 81 attached, preferably by a snap-in connector 95 a. The vertical profile parts are on vertical components of the facade structure or attached to fixed field wings of the sliding door system.

The profile structure 95 is arranged such that it displaces the offset 99 between Door level of wings 1, 2 and facade level, i.e. it extends with their side facing the sliding sash close to the door level of the Sliding sash, preferably up to just before the profile frame 92 of the sliding sash. It engages under the drive box 60 in the area of the drive 4 and covers offset 99 between wing and facade.

Insulators 100 are also inserted in the profiles of the profile construction 95, so that the passage of heat and fire is prevented.

In modified exemplary embodiments, the drive box 60 can also be used insulating material, e.g. B. clad with panels outside or inside, and so in addition or instead of the profile construction 95, the offset 99 against Block fire entry. The insulators 100 can be on the entire box or located only on part of the box, e.g. only in the area of the offset.

The individual drive units can be provided with appropriate formwork or Encapsulation to be protected against fire, especially the locking unit, which in the Fire trap performs the emergency closure. Electrical can also be used Supply lines etc. must be coated accordingly or designed to be heat-resistant. The drive, in particular the rollers, can also be heat-resistant be trained to safely close the emergency closure even in the event of fire guarantee.
