&bgr; Fire protection composite profile

8 The invention relates to a frame construction made of frame profiles with the

9 features of the preamble of claim 1. Such frame constructions

10 tions are used to accommodate surface elements, especially glass panes

13 Such known frame constructions consist of profile bars, which are

U tically and horizontally arranged in such a way that in the final assembly state

is a rectangular frame for a surface element, in particular

ie form a pane of glass. Such frame constructions serve both as

&eegr; door frames as well as window frames. The frame constructions are suitable

18 is particularly suitable for installation in house facades that serve as post/

ig bar constructions. In addition to the described rectangular

20 shaped frames, other frame shapes are also known in which the

21 profile bars are curved on the one hand and on the other hand the

22 profile bars are not arranged horizontally and vertically to each other, in particular

23 In particular, there is no right-angled arrangement of the profile bars. The

24 The invention relates primarily to metal frame structures, in particular

25 aluminum.

27 In frame constructions, there is generally the problem of thermal

28 Insulation. In facades or masonry, the frame structures form

29 and the surface elements contained therein create undesirable thermal bridges.

This is undesirable for energy-economic reasons. In addition,

The problem is that the frame structures due to their poor temperature

&igr; A generic frame construction is known, for example, from 2 DE-U-91 08 751.1.

4 The frame construction described therein consists of profile steel tubes.

5 The first profile steel tube mentioned there serves as the inner shell and the third profile steel tube also mentioned there serves as the outer shell of a

7 tional frame construction. Between this inner and outer shell

8, the second profile steel tube, referred to as the middle profile steel tube, is located as a fi-

9 spacers. Between the middle profile steel tube and the outer

10 and inner shell serving as fire protection insulation

11. The insulating layers acting as outer and inner shell

12 profile steel tubes are each connected to the centrally arranged middle profile steel tube

13 using pins that penetrate the insulating layer. Several pins or bolts are placed between the inner and outer shell on the one hand and the middle profile tube on the other, which are then welded to the profile material.

is The advantage of this design is the inner contour of the middle profile

19 filstahlrohr resulting air gap. The fixing of the outer and inner

20 shell effective central profile steel tube holds the outer and inner shell with its

21 insulation layers at a distance. In this way it is possible to create an external

22 thermal insulation levels and an independent inner thermal

23 insulation level. Through the mentioned air gap both

24 insulation levels separated from each other. The heat conduction of the middle profile steel—

25 pipes in conjunction with the mentioned fire protection insulation is at least as

26 "bad" that the frame construction over a period of more than

27 1 hour of exposure to fire or to the effects of fire

28 can withstand the heat generated by the fire.

The disadvantage of this design is the complex process of connecting the products

31 welding processes required to join the filrohre together. Based on these

32 disadvantages, the invention is based on the task of assembling the general

33 standard frame profile. This task is achieved by the

34 The feature combination of claim 1 is advantageously solved.

36 The inventive fire protection frame construction consists of a

37 inner shell and an outer shell arranged at a distance from it. The

38 The outer shell and the inner shell are connected by a

&igr; brought fixing spacer. In the final assembly state, there is

2 see the inner and outer shell on the one hand and the fixing spacer

3 on the other hand, an insulating layer of thermally insulating and fire-resistant

4 inhibiting material. The essence of the invention is to construct the fixing spacer in two parts. In this way it is possible to have two separate

6 rate supporting frame. The outer supporting frame consists of the

7 Outer shell, its associated insulating layer and its associated

8 partial profile. The inner supporting frame consists analogously of the inner shell, the

9 its associated insulating layer and its associated partial profile.

10 The partial profile and the inner or outer shell can be easily

11 screwed, riveted and/or pinned together. It is not necessary

12 the labor-intensive welding process. This creates a material-locking

13 connection is replaced by a form- and force-locking connection, where

14 are considerably simplified by the assembly properties of the frame construction.

&igr;? The frame construction can be easily assembled by

is both partial profiles are connected to each other, i.e. in their final assembly state

19 was assembled as a fixing spacer. The one from the two

The fixing spacer consisting of 20 partial profiles can thus not only be easily

21 can be assembled but also disassembled easily and with ease.

22 This advantageously reduces any repair times. The exchange

23 of individual parts is advantageous compared to the state of the art.

25 Another advantage of the invention is that the assembly of the riveting

26 and/or screwing and/or pinning from the fixing spacer side

27. In addition, a significant advantage of the invention is

28 in that the insulating layers simultaneously act as spacers between the

29 inner and outer shell on the one hand and the fixing spacer on the other hand are so effective. Finally, the intermediate layer of the insulation—

31 layers between inner and outer shell on the one hand and fixing spacers

32 on the other hand, provides effective protection against damage to the insulating layers.

34 Due to the two-part design of the fixing spacer, the thermal

35 Behavior of the frame construction has been significantly improved. On the one hand, this new frame construction also has the air gap described above.

37 On the other hand, the division of the fixing spacer into two parts results in a

this labyrinthine heat flow in the fixing spacer, which

&igr; Thermal conductivity is further "deteriorated". In this way, the heat from

2 the fire-exposed side of the frame construction slower to the

3 non-fire-exposed side. The slowing down of the

4 Transport speed in turn causes the

5 Frame construction withstands fire or heat exposure longer than

6 known fire protection structures.

s The subject of the retroactive claims are advantageous further training

9 of the construction.

11 Claim 2 relates to a preferred material for the insulating layer. The claims

12 before 3 and 4 relate to a first embodiment of the fixing spacer. The

13 Fixing spacer is here formed by two mirror-image U-shaped

14 profiles. These U-profiles are connected in the final assembly state by a

15 foundation and/or riveting and/or screwing. The advantage here is the possibility of using commercially available U-

17 shaped extruded profiles, which reduces the material costs of the

is frame construction can be advantageously reduced.

20 The subject matter of claim 5 is a further, compared to the above-mentioned

21 Embodiment Inventively developed embodiment of the invention.

22 In this inventively developed embodiment, one

23 mounting profile and a clip-on profile are provided. The mounting profile and the

24 clip-on profiles can be snapped onto each other and form

25 a clip connection. This design is particularly easy to assemble

26 inexpensive because it is easy to install. Another advantage is that in addition to the

27 mounting profile and the clip-on profile no further fastening means are required for

28 Final assembly of the fixing spacer is required. The fixing spacer

29 is therefore exclusively made up of the two partial profiles

so (= mounting profile/clip-on profile). In this embodiment,

si the outer and inner support frame are therefore completely pre-assembled

32 and only need to be activated by applying a certain amount of force

33 are clipped together. The subject of claim 6 is the connection

34 of the outer and inner shell with the receiving profile or clip-on profile.

35 Claim 7 concerns the additional adaptation of the insulating layer to its

36 assigned shell.

&igr; Outer and inner shells designed according to claim 8 create the

2 Prerequisite for a mechanically stable enclosure of a surface element,

3 for example a fixed field, a window pane, a door pane or the like.

s Outer and inner shells designed according to claim 9 take into account

&bgr; that differently designed sealing strips are fixed to the shells

7. This makes the frame construction suitable for different

a flat facade parts to be enclosed, as the cost-effective

9 sealing strips only in the area of their clamping edges to the profile side

10 provided receiving groove must be adapted.

12 The frame construction according to claim 10 is, to a certain extent, universally usable.

13 because the clamping edges are easily exchangeable as part of the frame construction. The clamping edges only have to be adapted to the surface parts to be enclosed in terms of their structural dimensions and mechanical stability.

is Claim 11 relates to a preferred embodiment of a frame

19 construction. The sealing strips ensure a perfect

20 reaching fixed fixation of the glass pane to both support frames. The

21 Sealing strips contribute to the insulating effect of the frame construction

22 is improved and the desired room temperature of an interior is constant

23 can be maintained. This contributes to saving on heating costs.

25 According to claim 12, the glass pane arranged between the sealing strips

27 consists of two glass panes and a glass panel between the glass panes.

28 arranged gel filling. The gel filling is transparent in its initial state. The

29 The transparency of the fire-resistant glass pane is exactly the same as that of a normal glass pane. In the event of a fire, the originally transparent gel filling breaks open and forms a gel foam. The volume of the heat-resistant glass pane

32 The gel foam produced by the effect is compared to the volume of the gel filling

33 tion in the initial state is significantly increased.

35 The gel filling consists essentially of bound water. The entire

36 Disc construction advantageously consists of several

37 additional, individual superimposed inner glass layers

38 between the above-mentioned glass panes and intervening gel-

5 Evaporation is accompanied by an increase in volume of the gel layer, which increases the

6 Gel filling runs into the gap between the frame construction and the pane. The

7 The pane becomes blind during this evaporation process.

8 Temperature exposure causes the glass pane to crack, with the outer

9 glass layers are initially preserved, while the inner glass layers

10 begin to melt.

12 During the glass melting process, a mixture of the molten

13 glass on the one hand and the evaporating gel filling on the other. This

14 mixture runs into the air gap between the pane and the frame construction. is On the one hand, this dissipates heat. On the other hand, the mixture also serves to wedge the fire protection pane to the frame construction.17

19 In connection with the inventive frame construction, the

20 fire protection glass also has the advantage that the gel foam penetrates both the air

21 gap between the shells or the insulating layers and

22 as well as other air spaces which are in the area of the sealing strip—

23 any gaps that may be present. If further heat is absorbed,

24 the gel foam solidifies again, whereby the glass pane in the area of

25 air gap and is thus additionally wedged to the frame. The air gap is

26 Expansion space for the gel foam effective.

&bgr; Both shells 2,3 are designed as hollow profiles, whose shaft-like profile

io cavity 6,7 each runs in the longitudinal direction 4.

12 The outer shell 3 is designed as a rectangular hollow profile. In the longitudinal direction 4

13, the long side of the rectangle runs in the transverse direction 5 and the

&kgr; Narrow side of the rectangle in span direction 8. The span direction 8 runs

15 perpendicular to both the longitudinal direction 4 and the transverse direction 5.

18 legs of the profile strips 12,12' limit a

19 Air gap 13 (Fig. 2) in transverse direction 5 and in tensioning direction 8.

21 In the final assembly state, the inner surface 10 and the base surface 15 are

22 indirectly on the surface of the insulating layer 11,11' facing it.

23 For this purpose, the inner shell 2, the insulating layer 11 and the profile strip 12 are

33 Insulation layer 11' and the profile strip 12' are components of an outer supporting frame

34 mens19.

36 In Fig. 1 and Fig. 2, the two profile strips 12,12' differ in the

37 Length of their base surfaces 15 in the transverse direction 5. The base surface 15 of the profile strip 12' is in this case relative to the base surface 15 of the profile strip 12 in such a way
