Definitions

  • the invention relates to a fire-proof holder of at least one pane covering a building opening, with elastic sealing elements made of temperature-resistant material arranged inside and outside in the edge area, which are braced flatly over a central bolt with a support profile, the inner sealing elements being angled on outer legs of a U-shaped Flat support profile lie flat and the base of the U is detachably connected to a support profile side.
  • elastic sealing elements made of temperature-resistant material arranged inside and outside in the edge area, which are braced flatly over a central bolt with a support profile, the inner sealing elements being angled on outer legs of a U-shaped Flat support profile lie flat and the base of the U is detachably connected to a support profile side.
  • It is also used for double or multiple glazing, where glazing is understood to be the use of silicate glass or other suitable materials.
  • It is also used for vertical or inclined installation positions, e.g. with horizontal ceiling glazing of an industrial building opening or with a skylight (e.g. shed, gable roof
  • the elastic ones arranged inside and outside Sealing elements are preferably swelling or expandable mats or made of mineral fibers. Swelling or expandable mats combine the outstanding characteristics of resistance of the ceramic fiber (aluminum silicate) to high temperatures and thermal expansion of the vermiculite material (intumescent). They are storage mats or strips with holding forces that also increase with increasing temperature. In the event of a fire, the intumescent effect of the swelling mat results in an increased contact pressure that significantly exceeds the pre-tensioning force of the fire-proof bracket in normal operation.
  • the invention has for its object to develop a fire-proof bracket of the type mentioned in such a way that with a simple structure and good visual appearance, a reliable hold of the disc (s) is given even in the event of fire and the tightness of the bracket in everyday life Condition of use are ensured.
  • the object on which the invention is based is achieved in that an insulated drainage channel is integrated in the fire-proof holder.
  • the insulated rebate ventilation / drainage channel is formed by inserting a profiled seal in the support profile / holding profile, the heat transfer through the holding profile also being improved.
  • the shape of the profiled seal allows the tight connection of cross profiles, which are necessary for large-area glazing.
  • the profiled seal either sits at the top in the U-shaped cutout of the holding profile, or the elastic profiled support seal is provided on the underside of the holding profile, which is therefore mounted on the support profile via the aforementioned support seal.
  • the seal also allows a tight connection of cross profiles or crossbars to the system, the crossbars being designed like the perpendicular support profiles or rungs, but the retaining profiles of the crossbars have a lower height, so that a connection in a slightly higher second Level opposite the rung-holding profile is possible and the groove drainage is ensured by joints without capillary effect.
  • the outer legs of the holding profile or the support flanks can be set in an inclined position in order to improve the spring action in the direction of the sealing element and disc.
  • Another variant of the invention is characterized by a two-part holding profile, in which the drainage channel can be easily and securely represented in the area of the fastenings by means of an elastic flat band.
  • the support between the lower and the upper or inner and outer part of the holding profile to achieve an inclined position of the support flanks. This misalignment then also increases the contact pressure against the pane with the advantage of a longer service life in the event of a fire.
  • the fireproof holder has an insulating border which extends as far as the outer legs of the holding profile, the uncovered edge flanks of the outer legs pointing towards the inside of the room being approximately flush with the insulating border.
  • the insulating surround which can in particular be an insulating material such as a fire protection plate with an outer protective jacket, protects the support profile supporting the holding device in the event of a fire on the one hand and improves the visual appearance in the area of the holding device on the other hand in that the insulating surround extends to the outer flat Legs of the holding profile of the fireproof bracket is pulled, ie there is no larger gap between the leg and the insulating frame at this point.
  • the outer legs of the holding profile lie essentially parallel to the glass surfaces and do not end approximately with the width of the supporting profile itself, but only approximately with the width of the additionally provided insulating border.
  • the outermost edge flanks of the legs are not covered towards the inside of the room, but can warm up at this point due to the room temperature. In the event of a fire, this means that the edge flanks of the legs of the holding profile are exposed to a high temperature, with the result that the fully shaped holding profile can also heat up accordingly.
  • the panes 1 with the spacer elements of them 3 separate panes 2 made of fire protection glass clamped on the interior profile 4 by a fire-proof bracket 20.
  • One of the fire protection panes 1, 2 has the property that it does not shatter under the high thermal load that occurs in the event of a fire, but rather changes into a plastic state and deforms under the influence of gravity due to its own weight.
  • the fireproof bracket is thus created in such a way that the panes do not flow out of the bracket and the pane, eg pane 2, is held securely.
  • the fireproof holder 20 comprises a lower inner elastic sealing element 10 in the edge area of the inner pane 1 and an upper outer elastic sealing element 11 in the edge area of the outer pane 2, each of which has a strip shape.
  • the sealing elements 10, 11 are swelling mats with an intumescent effect, i.e. swell when the temperature of a fire increases.
  • the sandwich arrangement consisting of assigned outer and inner sealing elements, outer and inner disks and innermost spacer element 3, is braced by a holding strip 17 on the outside of the room and a holding profile 12 on the inside of the room with central vertical bolts 5 on the supporting section 4, preferably two edge areas of sandwich arrangements being braced and the fireproof bracket 20 outside the central bolt 5 is symmetrical with respect to the vertical plane which runs through the axis of the central bolt 5 in the direction of the horizontal support profile 4.
  • the support profile 4 is a rectangular tube made of steel and has an upper horizontal edge length of preferably 40 mm and a lateral vertical edge extension of different heights and has a thickness of 3 mm and more. With the exception of the upper support profile side, the support profile 4 is surrounded by an insulating surround 6, which in particular can be divided into three and each part of the insulating enclosure contains an insulating material 24 adjacent to the supporting profile 4 in the form of a fire protection plate and an outer protective jacket 25 in the form of an angled steel strip. Protective jacket 25 and insulating material 4 are screwed to the corresponding side of the support profile 4.
  • the holding profile 12 is a U-shaped angled flat strip, which is detachably connected centrally at the base of the U to the upper side of the supporting profile 4. It basically has outer horizontal legs 13 made of flat strip material, on which the associated inner sealing elements 10 lie flat under prestress.
  • the holding profile 12 is formed in one piece and roll-formed as a bent sheet metal part. With its base of the U, the support profile 12 lies snugly over the entire width of the support profile 4 located underneath and is bent at its two lateral ends by 90 ° upward, so that in the exemplary embodiment of the drawing two vertical support webs for an associated one located above it inner sealing element 10 are formed.
  • the support webs run approximately in the middle of the associated inner sealing elements 10.
  • the support webs have a 90 ° bend 19 inwards at the top and an inner subsequent 180 ° bend 21 outwards, which forms the outer leg 13.
  • the outer leg 13 extends beyond the width of the support profile 4 to approximately the thickness of the insulating border 6 there, which adjoins closely below to form a small gap.
  • the edge flank 7 of the outer leg 13 is approximately flush with the protective jacket of the insulating enclosure 6, but can also end shortly before the protective jacket 25 of the insulating enclosure 6 there.
  • a profiled seal 14 with a U-shaped cross section is accommodated, which fits snugly against the vertical support webs of the holding profile 12 and on the underside after the 90 ° bend 19.
  • the profiled seal 14 has a through hole.
  • the profiled seal 14 In the assembled state of the fire-proof holder 20, the profiled seal 14 firstly forms an insulated seam ventilation / drainage channel 16 and at the same time improves the heat transfer through the support profile and to the vertical support webs of the retaining profile 12.
  • the profiled seal 14 allows the tight connection of cross profiles due to their shape, which are necessary for large-area glazing.
  • the fully formed U-shaped holding profile 12 of the fire-proof holder 20 according to FIGS. 1 and 5 therefore has edge flanks 7 on the right and left at the ends of the outer legs 13, which are not covered towards the inside of the room and nevertheless have a good visual appearance, that the insulating border 6 is pulled to just below the edge flank 7, the insulating border 6 at this point touching the vertical support webs of the holding profile 12 flat.
  • the insulating enclosure 6 is not connected to the underside of the outer legs 13 and therefore does not assume any supporting function for the insulating glazing. It has been shown that an attachment profile designed in this way, which heats up practically exclusively on the edge flank 7, deforms only in the direction of insulating glazing due to the supporting effect of the insulated vertical web.
  • This deformation creates an additional force in the direction of the glass pane, which is sufficient to make the softening glass (eg pyran) last longer in the glass rebate pinch and thereby achieve a longer service life than previously known. This is particularly important for inclined or horizontal glazing.
  • softening glass eg pyran
  • the holding profile 12 has a U-shaped cross section in the inner region with a base of a U that is smaller than the width of the support profile 4.
  • the two U-shaped legs are on an upper point bent outward at right angles to form the outer legs 13 for a flat support of the insulating glazing.
  • the outer legs 13 have edge flanks 7 which extend approximately up to the protective jacket 25 of the insulating surround 6 there.
  • This exemplary embodiment also has a profiled seal 15 which is U-shaped in cross section, but which extends under the holding profile 12 and lies snugly on the upper side of the supporting profile 4.
  • the vertical webs of the holding profile can also expand in the direction of the insulating glazing in this embodiment variant and generate an additional clamping force for the insulating glazing.
  • the outer legs 13 of the holding device can also have inclined flanks without increased central pretensioning in order to improve the spring action.
  • the profiled seal 15 of the embodiment according to FIGS. 2 and 6 also creates a tight connection to the cross profiles due to its shape, as will be described below.
  • the exemplary embodiment of a fire-proof holder 20 according to FIG. 3 does not have a one-piece, but a two-part holding profile 12.
  • the upper part is approximately as shown in FIG 2 and 6, while the lower part has a precisely U-shaped cross section and extends over the entire width of the support profile 4.
  • a flat seal 23 is accommodated centrally between the two parts, which forms a drainage channel 16 together with the two parts of the holding profile.
  • the outer legs 13 of the upper part of the holding profile 12 again extend approximately to the protective jacket 25.
  • the edge flanks 7 can also be located lower with respect to the protective jacket 25, for example approximately 2 mm, as illustrated in the exemplary embodiment in FIG. 3 .
  • the drainage channel 16 can be easily and securely sealed in the area of the fastenings by means of an elastic flat band.
  • the support of the vertical web 22 between the lower and the upper part of the holding profile enables the support flanks to be skewed. This misalignment also increases the contact pressure against the glass and leads to a longer service life in the event of a fire than previously known.
  • the fire-proof brackets 20 of FIGS. 1 and 2 are shown, as they may have cross profiles or cross bars 9 according to FIG. 4, which run perpendicular to the assigned rungs 8.
  • the holding profiles 12 belonging to crossbars 9 have a smaller height b than the holding profiles 12 of the rungs 8, which have a height a.
  • the drainage channels 16, which are assigned to the crossbars 9 are higher than the drainage channels 16 of associated rungs 8. This ensures that the seams are irrigated without joints by capillary effects.
