DESCRIPTION

Building closure element with glazing as! as manufacturing procedure

The invention relates to a building closure element configured as a fire barrier closure element, in particular fire protection door leaf, with a surface-level glazing as well! as to a manufacturing process thereof.

From GB 2 264 972 A a fixed glazing with glazing frame based on hollow profiles of PVC synthetic material is known. In this case, a first frame is fixedly arranged in the building, and an auxiliary frame, which may be glazed, is coupled with clips in the main frame by means of an interlocking device protruding on one side above the main frame and in the other side above the auxiliary frame.

From GB 2 323 116 A a clamping device is known for a glazing unit that is configured as an interlocking device. In this case, a first element of the interlocking device is provided with a glass fastening strip in order to hold a front face of the moon.

A comparable construction and a glazing provided therewith are known from WO 2009/078777 A1.

From document DE 203 17 163 U1 a building closure element with surface level glazing is disclosed in a fire barrier configuration, in which a frame arrangement in the form of a frame construction has several cross-members swingarms that in each case can swing around a tilting axis that runs transverse to the glazing plane. For the placement of a moon arrangement, the swingarms are rotated to a retracted position where they do not protrude into the frame arrangement. In this state, an auxiliary frame of a moon arrangement is placed and this is interlocked by tilting the different swingarms. For securing in the retracted position and in the interlocking position, the swingarms are provided with an interlocking device that releasably hold the swingarm itself in relation to the frame arrangement on which they are supported. Both the construction and the assembly process is complicated in the case of this building closure element.

An example for a building closure element with surface level glazing in fire barrier configuration is disclosed in EP 1 586 734 A2. EP 1 586 734 A2 describes a fire protection door leaf with a frame arrangement in the form of a frame construction and a moon arrangement that is placed in this frame construction. The arrangement of the moon is essentially the same thickness as the frame construction, so that glazing is flush with the surface. To do this, the moon arrangement is configured based on several moons with spacers between them. To hold the various moons, the outer edges thereof are wrapped by thin edge strips of fastening plates. With this, the moons are housed between the spacers and the edge strips. The construction as a whole is suitable for the fire barrier, that is, it resists, according to the corresponding regulations, an exposure to fire on one side for a minimum time. Although by this construction a surface level glazing can also be created for a fire barrier building closure element, by virtue of the wrapping edge strips a built-in element is still always present. In addition, the construction of fastening is relatively complicated to manufacture as! how to ride Document DE 203 17 163 U discloses a building closure element in accordance with the pre-characterizing clause of claim 1. Mission of the invention is to create a building closure element with glazing with which a glazing can be achieved by surface level also in the case of a fire barrier configuration with a simple manufacturing capacity and a simple assembly.

This problem is solved by a building closure element with the characteristics of claim 1.

An advantageous manufacturing process for the manufacture of such a building closure element is the subject of the subordinate claim.

Advantageous embodiments of the invention are subject to the dependent claims.

The invention creates a building closure element, configured as a fire barrier closure element, with surface level glazing, comprising a frame arrangement and a moon arrangement to be placed in the frame arrangement, and a device for interlocking to fix the moon arrangement in the frame arrangement.

In accordance with the invention, it is provided that the interlocking device is completely housed between at least one outer peripheral front face of the moon arrangement and a front face of intrados, oriented towards the previous one, of a glazing hole in the arrangement from Marco.

With a locking device, on the one hand, a simple fixing and a very simple assembly of the moon arrangement can be achieved. In addition, an interlocking device can be easily manufactured and assembled in a simple way. In an embodiment according to the invention, the interlocking device can be inserted completely hidden in the area of the front face between the moon arrangement and the internal intrados. With this, it is possible to dispense with clamping bars. A full surface level glazing can be created, this type of glazing being basically suitable also for fire barrier constructions.

In order to continue simplifying assembly, it is provided in accordance with the invention that the interlocking device has a stop to limit the movement of engagement after the interlocking. In the case of an assembly of the moon arrangement, the moon is then introduced into a hole in the glazing of the frame arrangement until the interlocking device is engaged. In this interlocking position, the moon arrangement is held in position, on the one hand, by means of a socket and, on the other hand, by the stop.

The interlocking device has, according to the invention, a first element to be fixed to the moon arrangement, and a second element to be fixed to the frame arrangement. By inserting the two elements of the interlocking device, the moon arrangement is thus connected with the frame arrangement. One of the two elements is an interlocking element with an elastically movable and prestressed coupling element in a hooking position. The other element of the interlocking device is preferably a counter-support element for the interlocking device. The counter-support element has a gripping element, so that the hooking element is continuously applied in a manner in the gripping element and there! It can be interlocked.

In an additionally preferred embodiment, stop areas of the stop are formed in the interlocking element and the counter-support element. With this, the interlocking device as a whole can only be configured by two elements, so that it can be fixed in a simple manner to the arrangements. A particularly simple construction and also suitable for the fire barrier is achieved when the elements of the interlocking device are made of metal, in particular steel, and more particularly of metal sheets. Preferably, at least one of these metal sheets, which form elements of the locking device, is bent several times. By means of curvatures that protrude from the metal sheets, for example, the buffer zones can be configured. In addition, the coupling element can be configured, for example, by means of a curved sheet tongue. The gripping element can be configured, for example, by a stepped curvature of one of the metal sheets.

Basically, it is sufficient that the panel arrangement and the frame arrangement are only fixed to one side of a glazing flange of the interlocking device. For example, the moon arrangement and the frame arrangement could be configured so that they fit inside each other on the opposite face, for example, by means of a forward-reverse configuration. Then, the coupling to this forward-reverse configuration could be carried out first and tilted next to the moon arrangement, in order to fit the interlocking device in this way. In particular, in the case of a fire barrier configuration, however, it is preferred to obtain joints as small as possible. In the case of correspondingly thick building closure elements, then a tilt to be carried out for assembly is difficult due to the possible slope between the moon arrangement and the frame arrangement. Therefore, according to a particularly preferred embodiment, it is envisaged that the interlocking device is provided next to several faces of a glazing edge, in particular on facing faces. With this, the moon arrangement can be displaced approximately perpendicular to the plane of the hole in relation to the frame arrangement until the locking devices engage.

In a particularly preferred embodiment, at least one of the elements of the interlocking device is made as a frame or made in a frame. This may be, for example, a profiled frame of the glazing that surrounds the moon arrangement and is connected to the panel arrangement. In the frame stringers of this profiled glazing frame, for example, one or more interlocking tongues may be configured, so that at least one interlocking device is present on each of the outer front faces; preferably, in each of the front faces several interlocking devices are present. The second element of the interlocking device may be configured in a profiled intrados frame that is provided in a surrounding manner in the internal intrados area of a glazing hole.

The first element of the interlocking device to be arranged in the arrangement in the moon arrangement is preferably fixed in the associated front face of the moon arrangement. This can happen by any type of suitable fixation such as, in particular, by casting in the moon arrangement, sticking with the moon arrangement or also by engaging with continuity of shape, for example by way of a groove-spring joint .

Also a fixation of the second element of the interlocking device to be arranged in the frame arrangement can happen by any suitable means. Preferably, this element is fixed by a plurality of screw fasteners or the like in the frame arrangement.

The invention is particularly suitable for creating surface level glazing, also in fire barrier constructions.

Particularly preferably, the building closure element is configured as a door leaf. More preferably, the door leaf in a fire barrier construction is configured as a door leaf of a fire barrier door. Accordingly, in the case of this preferred embodiment, the frame arrangement is a door leaf frame or a door leaf element with a glazing cutout. In a glazing hole in the door leaf frame or in the glazing cutout of the door leaf element, the moon arrangement can then be locked in place by means of the interlocking device.

A particularly cost-effective manufacturing mode for door leaf elements in fire barrier constructions is the so-called box-cover construction mode in which a metal sheet - as a rule steel sheet - is shaped as a box that It is closed by a second metal sheet in the form of a lid. Inside the cavity formed in this way are then insulated layers that provide a good fire barrier. In the state of the art different steel sheet doors of this type are described in fire barrier construction. Most of the time, in this case the plate of the box and the sheet of the lid in their edge areas are complexed and welded in a complex manner, so that the edge areas also resist in the event of a fire . A firm union of this type of metal sheets in the edge areas has, however, also disadvantages, in particular in relation to a complex manufacturing, as well! as in relation to the formation of heat bridges and, in addition, in relation to the so-called bimetal effect: if one face of the metal sheet is heated particularly strongly in relation to the other, then it expands much more, which leads to tensions and thus to curvatures of the door leaf.

Attempts have therefore been made to continue improving fire barrier constructions of this type. One approach to a simpler large-scale industrial manufacturing is a large surface bond between the metal sheets and the insulation coating. A glue of this type can, however, pose problems in the case of surface-known glazing constructions hitherto known, since the glue usually does not generally resist in the event of fire and, consequently, the metal sheets in The area of the edge of the glazing does not offer absolutely a reliable basis for fixing glass fasteners. Precisely joints of elements such as the glazing joint between the arrangement of the moon and the arrangement of the frame are particularly critical, however, in the case of fire barrier constructions.

Therefore, precisely in the case of glued fire barrier constructions, the fixation is offered in accordance with the invention between the moon arrangement and the frame arrangement by means of an interlocking device. The interlocking device can be configured and fixed inside the intrados device and, thus, relatively protected and independent of the fixing of the layers of external metal sheets. The use of the interlocking device for fixing the arrangement of the moon is, therefore, particularly preferred in the case of constructions with large surface bonding between the metal sheets and the insulation layer.

According to another aspect, the invention also creates a process for manufacturing the building closure element with glazing flush previously described, characterized by

a) fixing a first element of the interlocking device in the moon arrangement,

b) fixing a second element of the locking device in the hole of the glazing in the frame arrangement,

c) place the moon arrangement in the hole of the glazing and

d) fix the moon arrangement in the hole of the glazing by interlocking the interlocking device.

In the following, examples of realization of the invention are explained in greater detail with the aid of the attached drawing. In the show:

Figure 12, a section along the E-E line of Figure 1 showing a construction according to another form of realization.

A building closure element 10 is shown in Figures 1 and 2 in the form of a door leaf 12 for a fire barrier door 14 with glazing 15 flush with surface. The door leaf 12 has a frame arrangement 16 with a hole 18 of the glazing in which, for the formation of the glazing 15, a panel arrangement 20 in fire barrier configuration is incorporated. In order to fix the moon arrangement 20 in the frame arrangement 16 an interlocking device 22 is provided which is completely housed within a glazing joint 24 between a peripheral front face 26 of the moon arrangement 20 and an internal intrados face 28 of the frame arrangement 16. The moon arrangement 20 and the frame arrangement 16 have essentially the same thickness, so that the outer faces 20a, 20b of the moon arrangement 20 are arranged essentially flush with the outer faces 16a , 16b of the frame arrangement.

The frame arrangement 16 is configured as a door leaf frame construction 30 in fire barrier configuration. The frame arrangement 16 has for this purpose a first metal sheet in the form of a steel sheet 32 and a second metal sheet in the form of a steel plate 34, as! as an insulating sheath 36 between the two metal sheets 32, 34. The insulating sheath is glued over the entire surface with the box plate 32 and the cover plate 34 by means of a 1-K-PU 38 glue. In others embodiments, not shown here additionally, other glues are used for bonding. The insulation coating 36 has insulating strips 40, for example based on materials containing calcium silicates, in the edge area surrounding the hole 18 of the glazing. In the area of the insulation strips 40 there is a support device 42 in which the glazing fixation takes place.

The support device 42 is formed, in the exemplary embodiment shown in Figure 2, by a T-43 profile, which is here simply configured by means of a metal plate offset several times. With this, a T-profile slat is configured which runs continuously next to the intrados face 28 and is welded into lateral reinforcement profiles (not shown).

The interlocking device 22 has a first element 44 fixed in the panel arrangement 20 and a second element 46 fixed in the frame arrangement 16.

The two elements 44, 46 can be interlocked by means of an interlocking movement transversely to the plane of the opening of the hole 18 of the glazing. For this purpose, the interlocking device 22 has a stop 52 formed between the abutment zones 48, 50 in the elements 44, 46 of the interlocking device 22 to limit the interlocking movement.

The first element 44 is connected to the moon arrangement 20 and is arranged on its peripheral front face 26. The moon arrangement 20 is formed by several individual moons 54 that are joined together. The same joining technique can be used to join the moons 54 to fix the first element 44 in the moon arrangement 20. A laundry with the moon arrangement 20 or a glue or the like is imaginable. In another embodiment, not shown here in greater detail, the first element 44 has several highlights, which are continuously applied in complementary joints in the arrangement of panel 20, in order to keep the first element 44 fixed in the moon layout

For secure fixation, the first element 44 is part of a profiled frame 56 of the glazing present around the entire periphery of the moon arrangement 20, which is depicted in greater detail in Figure 11. As can be seen by Figure 11, in this case several interlocking devices 22 are provided for each front face, so that the moon arrangement 20 can be fixed on each of the four peripheral front faces 26 with at least two interlocking devices 22.

Also the second element 46 is preferably arranged in a frame that is present in a surrounding manner within the intrados of the hole 18 of the glazing and which in the following is designated as a profiled frame of intrados 58. In the embodiments shown, in each case the support device 42

it is present on each of the faces 28 of the intrados and forms in each case an intrados beam of the profiled intrados frame 58. In each of the support devices 42 are provided, as best seen in Figure 11, at minus two second elements 46 for the formation of the various interlocking devices 22. Each of the second elements 46 is firmly screwed to the support device 42 by means of several screw fasteners 60, here in the form of sheet metal screws.

In the exemplary embodiments shown, the first element 44 is configured as an interlocking element 62 having an elastically prestressed coupling element 64. The second element 46 is configured as a counter-support element 66 with a coupling element 68 housed in a locked manner in the coupling element 64.

The more precise structure of the interlocking element 62 is explained in the following in greater detail with the aid of the representations in Figures 3 to 6.

The interlocking element 62 forming the first element 44 is formed on the basis of a metal sheet 70, in particular steel sheet, curved several times, and has as a coupling element 64 a sheet tongue 72 disengaged outwardly and bent towards outside. The sheet metal 72 is surrounded by a flat area 73 of the sheet metal plate 70. Next to the zone 73 of the plate, the sheet metal 70 is raised so that it protrudes on the same face as the tongue sheet metal 72, so that a stepped flank 74 is formed which forms the abutment area 48 of the first element 44. The sheet tongue 72 is bent outwardly oriented such that a free end thereof is directed towards the flank stepped 74. On the face of the stepped flank 74 away from the sheet tongue 72, a stop bevel 76 is joined to the stepped flank 74 which ends at an edge strip 78 that runs parallel to the area 73 of the plate.

In the following, the structure of the second element 46 is explained in greater detail with the aid of the representations of Figures 7 to 10. The counter-support element 66 forming the second element 46 is formed by a metal plate 80 also curved several times, that it is provided for the formation of a step 82 with a bend 84. A stepped flank 88 formed by the bend 84 serves as a gripping element 68 that can be grasped behind by the sheet tongue 72. A first area of edge 90 that joins the bend 84 is provided with holes 92 for the accommodation of the screw fasteners 60. The holes 92 are configured in an elongated manner in order to be able to do so! an adjustment of the position of the second element 46. A second edge zone 94 that joins the bend 84 on the other side excels in use according to the standards protruding inwards into the hole 18 of the glazing and is housed in the state of interlocking shown in Figure 2 between the sheet tongue 72 and the stepped flank 74. The free edge 96 of the second edge zone 94 forms the abutment zone 50 of the second element 46 of the interlocking device 22.

During manufacturing, the procedure is that the hole 18 of the glazing is cut out of a door leaf on its entire surface in the box-cover construction. The intrados area is then provided with an insulation strip 40. The support device 42 is welded with the reinforcement profiles and the reinforcement brackets in the glazing hole in the intrados area. The second element 46 is screwed with the screw fasteners 60 to the support profile 42. This results in the construction of the door leaf frame 100 with the hole 18 of the glazing and several second elements 46 as shown in Figure eleven.

The moon arrangement 20 is provided, for example, with the first elements 44 fixed in the manufacturing workshop for the moon arrangement 20. Figure 11 depicts only the profiled frame 56 of the glazing housing the moon arrangement 20 with the first element 44 fully configured thereto, but without the moons 54. When the moon arrangement 20 is fixed in the profiled frame 56 of the glazing, the moon arrangement 20 of the mounting direction shown 102 is introduced perpendicularly to the opening plane in the hole 18 of the glazing until the sheet tongue 72 slides over the shoulder formed by the second edge area 94 and fits behind the stepped flank 88, bumping the edge 96 into the stepped flank 74 of the first element 44.

The glazing joints 24 are provided, according to the needs, possibly in addition to strips of an intumescent material. These strips of intumescent material (not shown) may already be provided above, in particular in a groove in an area between the T-profile 43 and the box plate 32 or the cover plate 34. The remaining area of the joint 24 of the Glazing is cast from both sides with a sealing material (not shown), such as, for example, silicone.

Figure 12 shows another modified embodiment of a glazed fire barrier door leaf 12 in a representation comparable to the representation in Figure 2. This embodiment corresponds, with the exception of the configuration of the support device 42 , to the embodiment previously represented with the aid of Figure 2. Corresponding parts are provided with corresponding reference symbols.

In the case of the second embodiment, the support device 42 has two angular profiles 104 and 106. A first angular profile 104 is fixed with a branch 104a to the box plate 32, and a second angular profile 106 is fixed with a branch 106a to the box plate 34. The remaining branches 104b, 106b of the two angular profiles 104, 106 overlap one another and thus reinforce! the intrados zone of the hole 18 of the glazing. Between these branches 104b, 106b that run perpendicular to the plane of the hole is incorporated an insulation strip 108 of a fire barrier material; Several layers of the insulation strips 40 are provided below. The screw fasteners 60 are applied through both overlapping branches 104b, 106b. Moreover, the structure of the second embodiment is equal to that of the first embodiment.
