Definitions

  • the invention relates to a method for partitioning unfinished building openings in component walls or ceilings that delimit the fire compartment.
  • the invention also relates to a fire protection cushion suitable for this method.
  • the invention relates to a partitioning element which is also suitable for this method and is prefabricated as a finished part.
  • the invention also relates to a frame adapted to this method for producing the reveal of a shell opening to be partitioned off in a component wall or ceiling which delimits the fire compartment.
  • the partition is a wall or ceiling part, which means that it must have the fire resistance of the wall or ceiling.
  • the partitioning like the rest of the wall or ceiling, must withstand fire, for example 90 minutes or 180 minutes; the increase in temperature outside the fire area may not exceed 140 degrees on average compared to the initial temperature, but may not exceed 180 degrees at any measuring point. Furthermore, no ignitable gases and no smoke may pass through the partition.
  • Fire protection cushions are known for the subsequent filling of bodyshell openings, which can be removed and reinserted into the openings.
  • These pillows have a filling made of non-flammable mineral wool and are covered with a non-flammable textile glass fabric that is soaked with insulating layer formers that react to heat in the event of fire.
  • the fillings can also consist of other substances that change to a solid ceramic mass in the event of a fire.
  • the pillows have a plastically deformable shape, since the filling is in the form of numerous small particles in the surrounding textile glass fabric envelope. Because of their great deformability, the risk that such cushions accidentally fall out of the opening is relatively great. Also, the degree of utilization, due to the compression that occurs during installation and the time required to fill an opening in the shell with these pillows, is fairly substantial and hardly economically viable.
  • a fire protection device for an encapsulated cable duct through building walls is known.
  • Small strips of water-containing sodium silicate combined into small packages are used as fire protection bags, which are provided with small amounts of organic additives and reinforced with glass fibers and / or glass fabric and are coated at least on the top and bottom with epoxy resin.
  • the strip packs are covered with a film and sit in a U-shaped channel provided with a lid. This channel is also closed on both ends by a seal. At temperatures of more than 100 degrees Celsius, the strips foam up and thereby form an inseparable, heat-resistant foam layer.
  • this fire protection device only becomes effective at temperatures inside the partition of over 100 degrees Celsius and thus only with a time delay, the fire protection device must be sealed on the end face with a smoke and fire-resistant asbestos foam. These seals on the end face must lie tightly against the lines that are led through the partition. This means that the fire protection device as a whole cannot be installed in the wall or ceiling in question when the structural opening is made.
  • the object of the invention is to find a partitioning method for the stated purpose and to design fire partitioning elements specially adapted to this partitioning method in such a way that the disadvantages indicated above the known methods or the known fire insulation elements can be avoided and an economically justifiable and nevertheless fire protection technically perfect insulation is made possible.
  • fire protection cushions which can be removed again in the openings, in that the fire protection cushions are already made in the component wall in question when the structural openings are made blanket.
  • fire protection cushions are already used in the manufacture of the prefabricated parts instead of the previously customary plastic fillers. This saves on the one hand the non-reusable plastic fillers and the effort required in connection with the subsequent partitioning.
  • the effort to create and seal corresponding openings can also be reduced.
  • the effort involved in walling in the fire protection pillows is hardly higher than that required by the conventional method of making openings. The saving arises from the fact that the subsequent effort in connection with the partitioning of finished shell openings is eliminated.
  • a fire protection cushion that is particularly suitable for this process is characterized by the fact that it has an outer shell made of non-flammable textile glass fabric, in which a filling made of non-flammable mineral wool is present, and that the filling consists of a single body having the shape of a cuboid or cube consists in that the body consists of non-compressible mineral wool, to which very small amounts of organic binders have been added; Furthermore, the outer cover of this fire protection cushion is surrounded by another cover made of non-flammable textile glass and casing and filling are dimensionally stable under the influence of fire.
  • the organic binders mean that the mineral wool can be provided in the desired cuboid or cube-shaped form.
  • the invention thus makes surprising use of the knowledge that very small proportions of organic binders are not harmful in connection with this fire protection cushion; this way, these fire protection cushions do not lose their strength and shape even when exposed to fire, as official material tests according to DIN 4102 at material testing institutes have shown.
  • Such a fire protection cushion ensures a full and, to a certain extent, elastic adaptation of the cushion to the reveal of a structural opening or to other pillows.
  • the interaction of the two shells also ensures the compression required in practice as well as the elasticity and deformability of the fire protection cushions.
  • a fire protection cushion of this type is suitable both for the very rapid subsequent partitioning of already existing structural openings, and also as a “masonry body” or “filler” when producing openings to be partitioned off already during the production of the relevant structural openings.
  • the angular shape of the fire protection cushion enables a straight surface adjustment and therefore favorable conditions for the pressing of the cushion both with each other and with respect to the reveals of structural openings; the angular shape of the pillow also prevents the pillow from accidentally falling out of the opening or slipping out.
  • the seams of the cover are also made with threads made from 100% non-flammable textile glass.
  • a partitioning element is used as a further, very essential feature of the invention
  • Prefabricated part specified which consists of a surrounding frame and fire protection cushions, which are present in the area enclosed by the frame.
  • the fire protection cushions are available close together within the frame.
  • Such a partitioning element can be used as a prefabricated part, as it were, as a filler in the manufacture of structural openings.
  • such a cover can be implemented in a favorable manner with an approximately 1.5 mm thick metallic or 3 mm thick plastic plate.
  • the frame to be preferably used in the method according to the invention and in connection with the above partitioning element according to the invention for producing the reveal of a shell opening to be partitioned off in a component wall or ceiling that delimits the fire compartment is characterized in that the outside of the Reveal part of the frame projecting a cantilevered part.
  • This cantilever part which according to a proposal can be one leg of an angle profile, the other leg of this angle profile then being attached to the frame, ensures that the frame is held securely in the corresponding wall or ceiling.
  • this cantilever part is not a full profile but with a bulging or arching - after kind in particular a profile - is formed, can be achieved by the bulge on the one hand, that the connection between the frame and the component or the pillows located on the other side can be made positively, and on the other hand, the longitudinal expansion of the frame across the opening is extended: the frame, which is strongly heated up in the event of a fire, is available to dissipate the high temperature across the building by increasing the distance by the amount of bulging.
  • the bending stiffness of the frame increases considerably due to the above measures. In suitable cases, it is therefore even possible to dispense with falls when making openings in masonry walls.
  • the bulge in the frame can be sized so that a fire protection cushion can be placed in it.
  • the frame there is an approximately right-angled bend on at least one longitudinal side of the frame, which projects in particular into the opening area enclosed by the frame.
  • This bend can then be advantageously used both for attaching a cover that laterally covers the opening area and as a system for sealing material located in the opening area, such as. B. use the fire cushion.
  • the fold also has the advantage that an additional compression of the existing fire protection cushion can be achieved at the circumferential opening edge by means of so-called adjustment cushions.
  • Such a frame can be used in particular as a ceiling frame and thus to seal off a shell opening in a component ceiling that limits the fire compartment if at least three hollow profiles are attached to the inside of the reveal side of this frame, if the longitudinal sides of these hollow profiles are also perpendicular to the one enclosed by the frame Opening plane are aligned if, in addition, the hollow profiles have an internal thread, into each of which a rod-shaped member having an external thread can be screwed to different extents, and if the links are finally fastened to a frame surrounding the frame at a distance and collar-like and the frame has an internal step has on which a cover plate closing the opening area can be supported.
  • the frame is still used to hold bulkhead material such. B. the fire cushion.
  • the hollow profiles which are attached to the frame in particular on the inside of each corner of the frame, serve to support the cover plate, which covers the shell opening closed with bulkhead material from above, and also as a stop bar, which can be adjusted in height with respect to the frame and thus the shell. and can thus be adjusted to the desired height of the finished floor.
  • An opening 11 is present in a wall 10.
  • This wall opening 11 is filled with fire protection pillows 12, of which only three are shown as solid lines.
  • the pillows 12 have an approximately cuboid shape (FIG. 3).
  • the reveal of the wall 10 is formed by a frame 13 in the illustration in FIG. 2, so that the cushions 12 adjoining the reveal are in the immediate vicinity Do not come into contact with the frame 13 and not with the wall 10.
  • Each of the pillows 12 has an inner body 14 which has a cuboid or cube-shaped shape.
  • This body 14 is surrounded by an inner shell 15, which in turn is completely surrounded by another outer shell 16.
  • Both the two shells 15, 16 and the body 14 are made of non-combustible material.
  • the angular shape of the body 14 enables such bodies to be stacked on top of one another and thus the use of such fire protection cushions as "masonry stones" as it were.
  • the two shells 15, 16 allow such a "masonry stone” that the same has a certain elasticity and resilience, so that it is press-fitted into an opening 11 - directly against a wall or indirectly adjoining it via a frame - with an immovable fit can.
  • the presence of a second shell has the essential advantage that when direct walling in or concreting in a corresponding pillow, only one of its outer shells forms a firm connection with the masonry or concrete, while the other inner shell remains elastic.
  • the frame 13 has a central, U-shaped part 17 and adjoining, outer U-shaped parts 18 and 19, respectively.
  • a non-combustible cushion 20.1 tightly fitting which is material correspond to the pillow 12.
  • the cushions 12 adjoin the U-shaped part 17 of the frame 13 and are press-fitted into the frame-shaped frame 13.
  • the pillows are as long as the wall 10 is strong. With vertical walls, it is practically impossible for pillows 12 to fall out of the opening 11 unintentionally.
  • lines 21 are to be passed through the opening in the future, a corresponding number of fire protection cushions must be removed from the opening at the corresponding points. In their place, after laying the lines 21, the space between the latter and the pillows still present is filled with a known, hardening bulkhead. Both the area of the bulkhead and the area filled with fire protection pillows are each fire-safe, both individually and as a whole. Due to their special shape and design, the subsequent routing of lines through an opening is very easy.
  • the frame 22 shown in FIG. 6 also has a central, U-shaped part 23, to which angular parts 24 and 25 adjoin in each case towards the outside.
  • the frame projects into the wall 10, as a result of which it is firmly seated in the same.
  • the cushions 12 are again stacked on top of one another in a press-fit manner, while in the central, U-shaped part 23 there is in each case a size-adapted cushion 20.2.
  • the angled design of the frames in the area of the wall 10 causes a greater length of the frame across the wall, which in the event of fire favors the heat dissipation of the strongly heated frame across the wall, so that the permissible temperatures on the wall side facing away from the fire not be exceeded on the metal frame.
  • the angular outer parts 24, 25 have a bend 26 and 27 running in the wall plane.
  • Several plates 28 are screwed to two frame parts of the frame opposite the wall opening, which cover the cushions 12 on both sides of the wall. These plates 28 are not required to increase the fire safety of the wall breakthrough; Rather, they serve as mechanical protection against fire protection cushions being pulled out or pushed out of the opening more or less unintentionally.
  • FIG. 7 shows a plurality of plates 28 which are aligned next to one another and parallel to one another, each of which is screwed via two screw connections 29, 30 to opposite frame parts of the frame - specifically to their bends 26.
  • pillows 12.1 with edge dimensions 10 cm x 30 cm x 20 cm (length x width x depth) are present in the 20 cm deep wall opening.
  • the edge dimensions can be varied over a wide range, so that any wall or ceiling openings can be filled with such pillows. Small bulges in the area of the frame, e.g. the middle or outer U-shaped parts 18, 19, 23 of the frames 13, 22 can be filled well with such pillows.
  • Each of these plates 28 has groove-like depressions 31 and 32, the cross-sectional shape of which depends on the material of the plate 28; So are in a plate made of plastic material 28.1, for example, a thickness of 3 mm, the grooves 31 are deeper than the grooves 32 in a plate 28.2 made of metallic material. Both panels 28.1 and 28.2 have on their narrow sides two holes 33 and 34, respectively, with which they can be screwed onto a frame outside the wall area.
  • the grooves 31 and 32 run crosswise over the respective plate 28.1 and 28.2, but do not abut each other in the respective crossing areas.
  • the areas of a plate framed by the grooves can be easily removed individually from the plate, for example by breaking them out of the plate.
  • the remaining webs 37.1 and 37.2 present on the long sides 35, 36 of the plates 28.1, 28.2 when any fields break out ensure that even after any fields of a plate 28.1 or 28.2 are broken out, the same by means of their holes 33 and 34 on a frame can remain screwed on.
  • plates 28.1 or 28.2 are to be used in connection with the frontal covering of wall openings which are not framed by a frame, the plates 28.1 or 28.2 can be screwed directly through their holes 33 and 34 to the wall.
  • the plates 28.3 show plates 28.3, from which either no fields or fields at different locations have been removed.
  • the plates 28.3 do not have three but only two fields, each in plate width, in an alignment parallel to the holes.
  • the number of grooves in a plate is largely arbitrary and depends, among other things, on the size of the plates.
  • two fields are not present in the left plate 28.31 in the middle, right area, while two fields are not present in the plate 28.32 lying next to it in the left, middle area.
  • two fields have been removed from plate 28.32 in the lower right area. From the third plate 28.33 there are two fields in the upper area and in the lower left area.
  • the fourth plate 28.3 is completely present.
  • the cushion 12.1 (FIG. 7) originally present there is removed from the frame 22 after detaching this panel, and a cushion 12.11 (10 cm x 5 cm x 20 cm) is left in its place. and on the right a pillow 12.12 (10 cm x 15 cm x 20 cm) was inserted, with lines 40 being passed through the building opening between these pillows.
  • the space between the lines 40 and the left pillow 12.11 and the right pillow 12.12 is filled fire-proof with a sealing compound 41.
  • the sealing mass 41 is thus visibly present in the area of the opening that is not covered by the plates 28.31 and 28.32.
  • While plates 28 are preferably present on both wall sides in the case of wall openings, such plates 28 are only required on the openings in the ceiling 50 on their lower side; the top of ceiling openings is regularly closed by a cover plate 51.
  • This cover plate 51 rests on a stepped step 52 which is present in a stop profile 53.
  • This stop profile 53 is flush with its top edge with a floor covering 54.
  • On the stop profile 53 is one Plate 57 protrudes into the opening area, in which there is an opening which is penetrated by the shaft of a screw 56 while the screw head rests on top of plate 57.
  • the screw 56 engages with its external thread in the internal thread of a nut, which is fastened to a frame 58 and protrudes vertically into the inner opening area.
  • This nut sits on top of a sleeve 59 which is fastened in each corner of the frame 58, which is rectangular in plan.
  • the stop profile 53 can be adjusted in height relative to the frame 58 so that the stop profile 53 is flush with its upper edge with the floor covering 54 to be introduced later.
  • An angle profile 60 is fastened with its one leg to the frame 58, while its other leg projects into the ceiling area. With the help of this angle profile 60, the frame 58 is held immovably in the ceiling. On the underside of the frame 58 there is a bend 61, which is aligned in the opening area, parallel to the lower edge of the ceiling. At the bottom of this turn 61 plates 28 are screwed. These plates 28 thus cover the pillows 12 present in the opening 50 from below. These pillows can be present in the ceiling opening 50 - just as in the case of wall openings - with their longer edge in the longitudinal direction of the opening - as shown in FIG. 12 - or in the transverse direction in the opening.
  • the sleeve 59 present in each corner of the frame 58 is so small in cross section that it does not hinder the installation of a cushion in this corner. If necessary, there is also the option of filling the corner area with a so-called stuffing pillow or with a precisely fitted pillow.
