DESCRIPTION

Surface element of a fire protection glazing, especially a glass fire protection door to prevent the passage of fire and smoke from one room to another in case of fire.

The invention concerns a surface element of a fire protection glazing, especially a glass fire protection door for the passage of fire and smoke from one room to another in case of fire, with a fire protection moon that It contains a fire protection agent and is secured by a frame consisting of frame profiles arranged on both sides of the fire protection moon and connected to each other by at least one connector.

Fire protection glazings of different kinds for room separation are known from the state of the art. They generally consist of a plurality of juxtaposed surface elements that each have a fire protection moon that contains a fire protection agent and is secured by a peripheral frame consisting of frame profiles arranged on the sides of the moon. fire protection and connected to each other by connectors. Due to the function of separating rooms, a glass door that is adequately designed for fire protection purposes and which is tilted in a tilt-up manner is frequently integrated or provided as a surface element of a fire protection glazing of this class. Its peripheral framework. Of course, this glass door can also be held directly in a fence that is arranged in a fixed side element.

A fire protection glazing of this class is known by the German utility model 9103671. This surface element features a glass door for fire protection purposes with a fire protection moon containing a foaming agent as protective material and that is fastened in a door frame consisting of frame profiles. Hollow steel profiles that are arranged on both sides of the fire protection moon and that are provided with a flat metal profile in their vertical edges are used as frame profiles. The metal profile joins and immobilizes one another the frame profiles located on both sides of the door leaf and determines the distance between these profiles, which may be different depending on the thickness of the door leaf. In practice, it has been found that it is disadvantageous that the construction of a door of this kind carried out on site is complicated and prone to failures and, in addition, thermal bridges are created through the large area joint of the frame parts of both sides, which make it difficult to comply with the legal requirements regarding fire protection. Finally, the metal profile is visible when the door is open and thus worsens the total aesthetic image of the door.

Document DE 39 07 280 A1 discloses a surface element according to the preamble of claim 1.

The invention is based on the problem of proposing a surface element of a fire protection glazing, especially a glass door for fire protection purposes, which avoids the above drawbacks, is of simple construction, can be easily mounted, optically unimpressive and satisfies high fire protection requirements through a wide thermal separation between the outer and inner frame parts.

The problem is solved according to the invention with the combination of the features of claim 1.

Therefore, the nuclear idea of the present invention consists in providing, by means of the ruffled arrangement of the edge side of the frame profiles with respect to the fire protection moon, a free space in which interior connectors and an insulation of fire protection, so that a very wide thermal separation between the fire side frame profiles and the frame profiles away from the fire is provided in case of fire. However, the union between the frame profiles can be released at any time, so that a change of the fire protection moon can be carried out in a simple way. The union device itself is of simple construction and can be mounted on site without complicated adjustment and positioning measures and is not very noticeable, which expands the possibilities of aesthetic configuration.

Preferably, the fire protection moon has two glass moons spaced parallel to each other by means of an edge assembly and the space enclosed by the edge assembly between the glass moons is filled with a fire protection gel. The frame profiles themselves can be configured as hollow profiles of rectangular cross-sectional steel, a different thickness of the mutually opposite inner and outer profiles can be provided when, for example, during the assembly of a door in a fire protection glazing large closing forces have to be absorbed due to the movement of the door on one of the sides thereof by means of the steel profiles of the corresponding door fence or adjacent surface elements.

The configuration and arrangement of the connectors according to the invention makes it advantageously possible for the fire protection moon to be sealed from the edge side to the respective frame profile by a dry joint instead of the wet-handled silicone gasket, considered up to Now as necessary. It achieves a

important simplification of assembly. It is advantageous to provide the slot-free space extending around the fire protection moon and corresponding to the frame thereof and also providing on each side of the surface element several connectors located at a distance from each other. According to the invention, the strip of fire protection material fills the free space in a substantially complete manner, hugs the connectors and is in contact with the frame profiles to optimize the fire protection action, the element of the fire element being screwed. immobilization of each connector in the socket of said connector through the strip of form to establish the immobilization by adjustment of form of the union bolt. The strip itself is advantageously constituted by a mineral fire protection material.

In addition, it can be provided to cover the strip externally with a strip of intumescent fire protection material to ensure a joint closure in case of fire. If the surface element is a glass door, it is achieved with a sealing strip of intumescent fire protection material that provides during the normal operation a lining of the shock edge to improve the optics and that, in case of fire, the existing door crack is sealed. In this case, the internally arranged connectors between the frame profiles are extraordinarily well protected and arranged so that they are not visible from the outside.

Preferably, the threaded part of the connector bushing is a screw, with metal frame profiles being preferred to provide as a threaded part a cylindrical screw screwed into a counter-nut of the frame profile. Likewise, it is advantageous to carry out the transverse hole in the wall of the socket of the connector as a pass-through and to provide it with a thread, the immobilization element being able to be a captive screw provided with a corresponding counter nut. Two transverse drills of this kind may also be provided cross-arranged relative to each other to facilitate the introduction of the immobilization element.

Just as the threaded part of the socket of the connector can be a screw, it is planned to configure the threaded part of the union bolt as a screw and also use here a cylindrical metal screw screwable in a counterscrew of the frame profile.

Preferably, the annular groove formed in the cylindrical part of the connecting bolt is provided with conical groove flanks to make possible, even in the case of an alignment not perfectly coaxial with the transverse bore, an exactly adjusted introduction of the immobilization element in the annular groove and secure immobilization in the tolerance zone of the adjustment. The frame profiles to be joined are immobilized and securely secure with respect to each other even if a certain slack is present.

If the surface element according to the invention is a glass door for fire protection purposes, it is advantageous to arrange the profiles of one of the sides of the fire protection moon in a decayed position with respect to the frame profiles of the other side in order to form a staggered revalve and configure the staggered revalve as a door stop, and the frame profile defining the staggered revamp can be arranged between a strip of metallic protection that penetrates the joint and is held by the connectors. The metal molding advantageously consists of aluminum.

Other details, features and advantages of the object of the invention emerge from the following description of the corresponding drawing, in which a preferred embodiment of a surface element according to the invention in the form of a glass door is schematically represented for purposes of fire protection.

The door T shown in figure 1 of the drawing contains a fire protection moon 1 which is constituted by two ESG 2 glass moons, 3 attached to each other and kept at a distance by means of a spacer 8 and a border edge assembly. PU, resulting in a closed interior space that is filled with a gel acting as a fire protection agent. The moon 1 of fire protection is held on all sides by a peripheral frame that is constituted by respective hollow profiles 4 and 5 of steel. The peripheral frame is fixed by means of hinges S to frame profiles 24 that belong to an adjacent surface element of a fire protection glazing that is not represented in more detail. Likewise, the door has on the opposite side to the side of the hinges a respective latch to actuate a locking mechanism not shown. Finally, above the glass door T is a skylight that is not described in more detail.

The surface elements of a fire protection glazing, adjacent to the door T are provided, according to Figure 2, with frame profiles 23, 24 of different thickness to absorb the high forces that come from the door drive. The hollow profiles of rectangular cross-section steel used in the exemplary embodiment as frame profiles 23, 24 have the different thickness described, the rear frame profile 23 being formed in the direction of closing of the door with a thickness three times greater than that of the front frame profile 24 in the closing direction. The representation of Figure 2 illustrates that on both sides the vertical profiles of the surface elements that receive the door are provided with frame profiles configured in this way.

The fragment of the glass door 1 shown in Figure 4 of the drawing shows the joining device, described below in greater detail, with which the fire protection moon 1 is fastened on both sides in the edge area by the Frame profiles 4 and 5 made in the form of hollow profiles of rectangular cross-sectional steel. Each of the two glass moons 2 and 3 is glued with a strip of elastocellular foam 22 and a silicone sealant mass 6 with the corresponding frame profile 4 or 5. Instead of using a silicone sealant mass 6, a dry joint can be mounted, for example in the form of a rubber profile, since with the joint device 7 according to the invention, the profiles are secured with one another.

The frame profiles 4 and 5 that form the outer frame and the inner frame are arranged on the edge side on both sides of the fire protection moon 1 protruding in a cantilever way in such a way that between the frame profiles 4 and 4 or 23 and 2 on both sides a slot-free space F is enabled in which the joining device is arranged in the form of connectors 7, a strip-shaped strip of protective material FS being arranged in the free space F Fire protection covering the connectors 7. In addition, the FS-shaped strip is covered externally by an intumescence strip 25.

The flown projection of the frame profiles has been carried out in such a way that a phased renvalso SF is formed. To this end, the frame profiles 4 on one of the sides of the fire protection moon are arranged so that they are offset (forming incoming) with respect to the frame profiles 5 on the other side of the fire protection moon due to the fact that frame profiles 4 of reduced width are used in comparison with the width of frame profiles 5. The stepped revamp SF formed in this way is configured as a door stop, the corresponding frame having a concordant shape. Between the strip of form FS and the frame profile 4 that forms the stepped revalidation SF, an aluminum metal frame 26 is disposed that penetrates the joint, is designed to reinforce the stop and is held by the connectors 7.

The joining device 7 according to the invention, whose pieces are represented in detail in Figures 5 to 10, keeps the frame profiles at a certain distance from each other and unites them in a releasable manner. The union device 7 is constituted by a connector bushing 11 according to figures 5, 6 and 7, a union bolt 9 according to figures 8, 9 and 10 and an immobilization element 10 which, according to figure 4 and figure 11, is configured as a set screw.

According to figures 5, 6 and 7, the connector bushing 11 has a configuration of a vessel-shaped steel with a cylindrical wall 12 that is crossed in crosswise by two through holes 13 which are provided with an internal thread, as can be deduced especially from figure 6 of the drawing. The thread is provided so that it is possible for the captive screw 10 used as an immobilization element to be screwed into the connector bushing 11.

Naturally, the connector bushing 11 has a bottom 14 and a hollow interior space 15 within the wall 12 which is constructed in the form of a blind hole in the exemplary embodiment shown. The upper edge of the wall is widened outward in the form of a ring to provide an enlargement of the seating surface in the frame profile 4.

From the bottom 14 of the connector bushing 11, a part extends with an identical axis to that of the hollow interior space.

threaded that can be screwed into the frame profile 5 and that is configured as a cylindrical steel screw 16. To make possible the screwing described, the frame profile 5 is provided, in a corresponding place, with a rivet nut 17 with countersunk head according to figure 4 of the drawing.

In figures 8, 9 and 10 the second element of the union device is represented, that is, the union bolt 9. Also this is made of steel and has a threaded part in the form of a cylindrical screw 18 for its union with the profile of frame 4 and a coaxial cylindrical part 19 for insertion into the hollow interior space 15 of the socket-shaped socket 11. The cylindrical part 19 is provided, at a certain distance from its free head end, of an annular groove 20 having conically shaped flanks according to the representation of the drawing. In the assembled state, this annular groove 20 is located on the axis of the transverse holes 13 of the connector bushing 11, so that the captive screw 10 screwed into it can fit into the annular groove 20 of the union bolt 9, a consolidation of the pieces with each other. Since the union bolt 9 is screwed with its cylindrical screw 18 into a rivet nut 21 with an internal thread that is inserted in the frame profile 4, the detachable union of the two frame profiles with one another can be established. The default distance. The union is schematically represented in perspective in figure 11 of the drawing in combination with figure 4 of the drawing, and in particular it can be carried out as follows the formation of the union:

First, the frame profiles 4 and 5 that form the outer frame and the inner frame of the fire protection moon 1 are provided, at the intended joint site, with the rivet nuts 21 and 17 or, alternatively, of a carved thread. Next, the connector bushing 11 with its cylindrical screw 16, provided as a spacer, is screwed into the internal thread of the rivet nut 17 and the union with the frame profile 5 is established. In front of this, the screw is screwed cylindrical 18 of the union bolt 9 in the rivet nut 21 of the frame profile 4, whereby the two frame parts are now prepared to hold and immobilize the fire protection moon 1. To this end, the frame profile 5 is positioned in a known manner on the fire protection moon 1 and the frame profile 4 is then applied from the other side against the moon 1 against fire protection such that the bolt of union 9 fits into the hollow interior space 15 of the connector bushing 11 and the bushing itself comes to be applied with its free edge as a stop to the frame profile 4. The distance has been chosen in this case so that the moon 1 of protection against Fire, on the one hand, is securely fastened within frame profiles 4 and 5 with its strip 22 applied by the edge side, made of elastocellular foam, but, on the other hand, the pressure applied is not so high that deformation and excessive pressure load of glass moons 2 and 3 can occur with the inner gel layer. Finally, by screwing the captive screw 10 as an immobilization element, the established joint is secured and secured, and an extraordinarily firm joint can be produced by the conical configuration of the annular groove 20 in the cylindrical part 19 to the union bolt with compensation for eventual tolerances , but which can be released again at any time, for example when a fire protection moon 1 has to be changed. It is expressly stated that the above description affects all the connectors used that are necessary to mutually join the frame parts that hold the fire protection moon in its entirety.

The frame profiles 4 and 5 are finally glued with the fire protection moon 1 in the edge areas by means of the silicone sealing mass 6.
