Description

The The invention relates to a wing or frame for a fire protection window based on PVC hollow section profiles and a fire protection filling, in particular a fire-resistant glazing.

Technical area

Fire window and fire doors are usually made of steel profiles manufactured, since steel profiles compared to plastic profiles a much higher softening or melting temperature exhibit. However, steel profiles have a very low thermal insulation and are for visual reasons as well as in the maintenance effort plastic windows inferior.

State of the art

From the DE 20 2066 44 U1 is a fire protection element on the basis of plastic profiles known in which in the reinforcing chamber of the frame profile, a lattice-like and flexible trained fire protection element is used. However, such a window does not meet the usual minimum fire protection performance, such as the F30 test.

From the DE 202 08 44 U1 is a fire-retardant window or door profile on the basis of polyolefins known as a material for the outer wall, in which by intumescent material in at least one cavity of the profile increased fire safety should be achieved. Also this construction is not sufficient for the production of windows and doors, which are to withstand a higher fire load (eg F30).

task

task The present invention is therefore a wing or a frame for a fire window or a fire door to provide that increased resistance reached.

Presentation of the invention

• – der Flügel bzw. Rahmen umfasst wenigstens vier Hohlkammerprofile auf der Basis von PVC-U sowie eine in den Flügel bzw. Rahmen eingesetzte Brandschutz-Füllung, insbesondere eine Brandschutzverglasung;
• – die Hohlkammerprofile auf der Basis von PVC-U weisen eine zentrale Verstärkungskammer sowie weitere Hohlkammern auf;
• – die Verstärkungskammern der Hohlkammerprofile des Flügels bzw. Rahmens weisen eine Metallverstärkung auf;
• – die Brandschutz-Füllung wird an allen vier Seiten auf der Außenseite und/oder der Innenseite im Randbereich durch einen durchgehenden, sich über die jeweilige Seite erstreckenden Metall-Haltewinkel gehalten, wobei
• – die Haltewinkel jeweils mit den Metallverstärkungen in den Verstärkungskammern der Hohlkammerprofile verschraubt sind.

The invention solves this problem by a wing or frame for a fire-resistant window with the following features:

• - The wing or frame comprises at least four hollow chamber profiles on the basis of PVC-U and an inserted into the wing or frame fire protection filling, in particular a fire-resistant glazing;
• - The hollow chamber profiles based on PVC-U have a central reinforcing chamber and other hollow chambers;
• - The reinforcing chambers of the hollow chamber profiles of the wing or frame have a metal reinforcement;
• - The fire protection filling is held on all four sides on the outside and / or the inside in the edge region by a continuous, extending over the respective side metal support bracket, wherein
• - The brackets are bolted respectively to the metal reinforcements in the reinforcing chambers of the hollow chamber profiles.

Especially the fire protection filling is preferred on all four sides both on the outside and the inside in the edge area through a continuous, extending over the respective side Held metal bracket.

When Frame becomes in this sense a frame with fire protection filling, under wing a sash with inserted Fire protection filling understood. The fire protection filling is generally a fire-resistant glazing, as they themselves A person of ordinary skill in the art is known per se.

It is essential to the invention that the fire protection filling in the edge area at least on the outside or on the Inside, but preferably on both sides, through a continuous, over holding the respective side extending metal brackets, which projects at least almost into the corner areas and - if at all - only has short breaks. It turns out that attachment over several shorter angles, arranged at a greater distance from each other are insufficient, since the fire-resistant glazing at the usual in the event of fire temperature loads in the unsupported areas very strongly, allowing fire gases and flames from the fire side to the other side can penetrate. In the inventive Execution, however, the passage of flames is reliable prevented.

The possibly continuous bracket are according to the invention respectively with the metal reinforcements in the reinforcement chambers the hollow chamber profiles screwed to the occurring in case of fire absorb considerable forces through the fire-resistant glazing to be able to.

According to a particularly preferred embodiment of the invention, the metal reinforcements of the hollow chamber profiles in the corner regions are connected to one another directly or indirectly via metallic corner angles to form a fixed frame. For this purpose, the corner angle can be arranged in the rebate area between casement frame and frame, which are screwed in particular with the metal reinforcements. After an alternative Embodiment are arranged in the Glasfalzbereich in the corner areas metallic corner angle, which are connected by screws to the metal reinforcements in the hollow chamber profiles. This is particularly useful in a fixed glazing, since there is no fold area between glare and sash. As far as in a fixed glazing in a frame of the frame is sufficiently secured in a soffit, this may possibly be waived on the corner angle.

All Fittings, reinforcing profiles, metal brackets and metallic corner angles are preferably made of steel, since Die-cast parts usually do not have sufficient heat resistance exhibit. The fittings are preferably with a mushroom lock equipped to provide adequate anchorage in the strike plates to reach. The strike plates are preferred with the metal reinforcements bolted in the reinforcing chambers to fire in case of fire to transmit the necessary forces.

According to a particularly preferred embodiment of the invention it is provided that fire protection materials are inserted in the steel reinforcements in the reinforcing chambers of the hollow chamber profiles, which achieve a cooling effect under heat - in particular by evaporation of crystalline bound water and otherwise have good heat and sound insulation properties. For this example, Promaxon ^® can - or Promatect ^® boards are used.

Furthermore, in areas that are particularly at risk from fire, strips or bands of intumescent, ie foaming heat stress materials and at the same time heat insulating materials used. These materials are known for example under the trade name Promaseal ^®.

The Fire protection windows and doors according to the invention have one - for one on plastic profiles based conception - surprisingly high resistance against Passage of combustion gases and flames as well as in relation to the shielding from heat radiation on.

Short description of the drawing

The Invention will be described below with reference to an embodiment and the drawing explained in more detail. Show it attended:

1 a view of a fire protection window according to the invention from the inside;

2 a vertical section AA through the frame;

3 a vertical section BB through the post;

4 a vertical section DD or horizontal section CC through the sash and frame.

Best way to execute the invention

This in 1 in the view from inside shown fire protection window 1 has a frame on the left side 2 with fixed glazing 4 and on the right side an inserted turn-tilt wing 3 with fire-resistant glazing 5 on. The frame is formed by the three Bendrahmen- and the middle post profile. The vertical section AA is in 2 shown enlarged. The frame 2 has a deep design typical of the Netherlands. In the middle large elongated hollow chamber is the steel reinforcement 8th used in a conventional manner. The steel reinforcement 8th is due to the used fire protection plate 15 with high heat load in case of fire cooled from the inside. Additional intumescent bands 16 in the reinforcement chamber, in the rebate area as well as in the wall connection area, in the event of fire, the protection against the passage of combustion gases and flames supplement.

In the frame 2 is in the rebate a standard fire-resistant glazing as a fixed glazing 4 used, with the fixed glazing 4 on the outside through the steel angle 20 and on the inside through the steel angle 19 is held. The steel angles 19 and 20 extend over all four sides of the window over its entire length and are at regular intervals through the glands 22 respectively. 21 - only indicated in the figures - with the steel reinforcement 8th screwed. Thus, in case of fire, a stable, supporting corset made of steel angles 20 . 21 and steel reinforcements 8th reached. In the corner areas of the frame 2 are additional steel angles 30 used. These steel angles 30 are also with the steel reinforcements 8th screwed. The sealing of the fixed glazing 4 opposite the frame profile takes place on the outside through the seal 10 , on the inside is the fixed glazing 4 through the glass strip 7 ' held.

In 3 is the cut BB through the post 6 and the turn-tilt wing 3 shown. The post 6 takes - like the frame 2 - the fixed glazing 4 on, with this fixed glazing 4 held both on the inside and on the outside by a continuous steel angle. The sealing of the fixed glazing 4 opposite the post profile takes place on the outside through the seal 10 ' , on the inside is the Festver glazing 4 through the glass strip 7 ' held. Between turn-tilt wing 3 and the post 6 the seal on the outside is made by the stop seal 11 , on the inside through the stop seal 11 ' ,

The steel angles are on the inside through the screw connection 21 ' and on the outside through the screw connection 22 ' with the steel reinforcement 9 connected. In the fold area 28 as well as in the field of fixed glazing and in the field of glazing of the wing intumescent bands are in different places 16 used, which foam under appropriate temperature stress and seal these areas to prevent penetration of fumes and flames.

In 4 is the horizontal section CC and rotated by 90 °, the vertical section DD according to 1 also shown enlarged. The frame 2 is there - how to 2 already explained - with the steel reinforcement 8th in the steel chamber and in the rebate area 28 with various intumescent bands 16 Mistake. Between turn-tilt wing 3 and frame 2 the seal on the outside is made by the circumferential stop seal 11 '' , on the inside through the stop seal 11 ' , In the steel chamber of the turn-tilt wing 3 is a reinforcing steel 13 used, the inside through the fire protection plate 14 protected or cooled. In the glass fold area 29 are - analogous to the holder of the fixed glazing 4 in the frame 2 - on the outside steel angle 17 and on the inside steel angle 18 provided by appropriate screwing 23 respectively. 24 with the steel 13 of the turn-tilt wing 3 are firmly connected. The steel angles 17 and 18 extend over the entire length of the four sides of the turn-tilt sash and thus reliably hold the fire-resistant glazing in case of fire 5 ,

Also the Glasfalzbereich 29 is circumferential with several intumescent bands 16 protected against the passage of fumes and flames. The fire-resistant glazing 5 is on the outside through the seal 10 '' and on the inside through the glass strip 7 held with an extruded seal. In the corner areas of the sash frame (turn-tilt sash 3 ) are additional steel angles 31 used with the reinforcing steel 13 screwed the sash. The steel angles 30 are with the steel reinforcements 8th screwed. For a firm anchorage in the masonry, the steel angles 30 possibly omitted.

The fixed glazing 4 and the fire-resistant glazing 5 is in a conventional manner on fireproof glass blocks 27 clogged in the respective folding area.

Between the frame and the surrounding masonry is circumferentially a mounting frame 25 inserted, which is outward at the seal 12 supported and on the inside by intumescent tapes 16 is supplemented. In the 2 and 4 is an additional mounting frame on the inside 26 purposed.
