Definitions

  • the invention relates to a fire-retardant partition with an at least partially made of metal profile beams, preferably square tubes, holding frame for at least one pane of fire protection glass, at least one surface-side flat side of the holding frame being provided with a cover made of a heat-resistant material, and in each case at the connection points between horizontally extending and vertically extending metal profile carriers of the holding frame, plug-in elements are fastened to the side surfaces of the one (first) metal profile carrier, which engage at the end in the profile of the other (second) metal profile carrier.
  • a fire-retardant partition of the type described above is known from DE-OS 35 08 078.
  • the plug-in connection of the metal profile carrier of the frame takes place in this design with the help of U-shaped plug connections, each with its web on the side surface of a metal profile carrier are screwed and inserted with their free legs into the profile of the other metal profile carrier.
  • This construction is very complex since threaded holes have to be cut into the side wall of the metal profile in order to fasten the plug-in elements.
  • the starting material for the U-shaped plug-in elements must be made relatively precisely, which can lead to difficulties in procurement when using the conventional structural steel profiles.
  • the installation of the partition consisting of prefabricated individual parts at the installation site also requires careful work.
  • the invention is based on the object, starting from the previously known construction, to simplify it in such a way that both the manufacture and the assembly are made considerably easier.
  • the plug-in elements are each formed by at least two spaced apart supporting bolts, which protrude through the (first) metal profile carrier and are firmly connected to it, that the (second) metal profile carrier on a side wall of its profile has at least one recess which is dimensioned such that it can be pushed transversely onto the supporting bolts and rests against the supporting bolts with an inner wall of the profile.
  • the support bolts are formed by strong clamping sleeves.
  • adapter sleeves simplifies production even further, since these are hammered into the through hole or pressed in and due to the spring action stuck frictionally in the through hole.
  • the assembly is simplified in that the frame profile parts provided with supporting bolts are first attached to the floor and ceiling at the installation site. Then the vertical profile parts forming the stands, which are provided with recesses at their ends, are pushed transversely onto the supporting bolts of the frame profile parts until the supporting bolts abut against the inner wall of the profile and are connected to the horizontal frame part, for example, by means of a stitching.
  • the horizontally extending metal profile beams forming the latches are then inserted between the already erected stands and are also inserted transversely onto the support bolts connected to them via the recesses and placed on the support bolts. Then the cover made of heat-resistant material and the glass retaining strips are first attached to one surface side of the frame, then the panes are inserted and fixed, and finally the other side of the holding frame is provided with the heat-resistant cover.
  • the through holes for the support bolts are expediently set so that they run closely along the parallel inner wall, which results in a high static load-bearing capacity without significant weakening of the profile cross-section.
  • the recess in the (second) metal profile carrier is formed by a cut of the carrier end which runs obliquely to its longitudinal axis.
  • This arrangement has the advantage that the recesses are already made from a strand material when the metal profile carrier is cut to length, since only a separating cut which is oblique to the longitudinal axis of the strand material is to be made in each case.
  • the second metal profile beams tapering downwards in a trapezoidal shape in the side view are then spaced between those provided with supporting bolts first metal profile carrier inserted and moved in the frame level against the support bolts until they come to rest on the wider part in the side view.
  • the second metal profile beam as a bolt, they are simply placed on the support bolt. A further definition is not necessary because the bolt is held immovably by the high weight of the fire-resistant glass pane supported on it.
  • the recesses are formed by a slot-shaped notch in a side wall and are arranged in an area facing away from the storage surface.
  • the metal profile carriers are separated from the strand material with a separating cut running perpendicular to the longitudinal axis, and the notch is then incorporated.
  • the width of the notch is slightly larger than the diameter of the support bolt, its length is slightly larger than the free collar length of the support bolt.
  • a spacer is inserted into the end of the (second) metal profile carrier, which is held on the wall of the (second) metal profile carrier after being pushed onto the supporting bolts.
  • the arrangement of such a spacer simplifies the assembly of the metal profile supports serving as stands, since this eliminates additional welding work during assembly.
  • the expediently telescopically insertable spacer into the end of the metal profile carrier is expediently dimensioned such that, after the metal profile carrier has been pushed on until it comes into contact with the support bolts, it fills the free space between the inner wall facing away from the contact surface and the support bolts, so that the plug connection is positive and in represents twist-proof connection with respect to the metal profile carrier.
  • connection points for example, a short full profile piece with a rectangular cross section can be inserted, which is held in its end position by its own weight, so that additional measures for fixing the spacer are not required.
  • the use of a spacer also offers the possibility of designing the connection points as a rigid connection, in which case the spacer is in each case fixed on the second metal profile support by means of shear bolts, the shear bolts advantageously being designed as screws and at the same time serving as fastening means for the spacer.
  • the spacer is formed by an essentially U-shaped profile piece.
  • the profile piece is expediently inserted with its free legs into the hollow profile forming the metal profile carrier, so that the web rests on the side wall of the other metal profile carrier having the supporting bolts. It is expedient if the leg of the U-shaped profile piece facing the supporting bolt has a support nose which is bent outwards at its end. This ensures a perfect telescopic displacement of the profile piece in the hollow profile of the metal profile carrier.
  • the U-shaped profile piece can expediently also be made so that the width of its web is greater than the width of the legs to be inserted into the hollow profile, so that there is a guarantee that the profile piece in particular when mounting as a stand at the upper end is not in the hollow profile can fall into it.
  • Fig. 1 shows a schematic representation of a storey-high and room-wide fire-resistant glass partition wall with a heat-resistant holding frame which divides the partition wall into several fields 1, 2, 3, 4 and 5 filled with panes of fire protection glass.
  • closed square tubes are provided as metal profile supports.
  • plug-in elements are attached to the longitudinal beams 6a running on the floor and ceiling at the spacing predetermined by the subdivision, in each case on the upper side for the respective vertically running beam 6b, the construction of which is described in more detail below.
  • the finished frame structure is attached to its outer surfaces by strip-shaped covers 7 made of a heat-resistant material, for example by means of self-drilling screws 8.
  • the strip-shaped cover 7 is dimensioned in its width so that it is seen in the frame plane, the width the metal profile carrier 6 protrudes so that it also contributes to the attachment of a pane 9 to be inserted into the respective frame field made of fire protection glass.
  • barrier material strips 10 preferably in the edge area, are glued to the inside of the metal profile carrier, which in each case delimits a field. Thin, angular metal strips 11 are then placed on these strips of barrier material 10 and lie flat on the barrier material strips 10 with one leg.
  • the covers 7 are provided on their side facing the pane 9 to be inserted in the edge region in each case with a circumferential clamping strip 12 made of a refractory or heat-resistant material, to which the pane 9 used comes to rest.
  • the disc 9 is held on the clamping strips 12 by the covers 7 on both sides.
  • FIG. 3 shows the connections of the individual metal profile supports to one another on a larger scale, specifically the areas A, B, C and D indicated in FIG. 1 in different embodiments.
  • the representation of the frame construction is limited to the connection points between the metal profile beams.
  • Embodiment A is primarily used for fastening a metal profile carrier 6b serving as a stand, that is to say a vertically running metal profile carrier 6b, on the horizontally running frame part 6a running on the bottom.
  • a metal profile carrier 6b serving as a stand
  • four support bolts 13 in the form of so-called clamping sleeves are held in corresponding bores in the metal profile carrier 6a in through bores on both walls of a square tube.
  • the ends of the support bolts 13 held in the tube wall can run flush with the outer surface.
  • the supporting bolts protrude slightly from the outer surface, since the underside of the metal profile carrier 6a forming the frame has a Insulating and sealing material is covered, in which the bolts can penetrate to a small extent.
  • the supporting bolts 13 are set at a distance from one another so that the metal profile carrier 6b serving as a stand, also a square tube with a corresponding cross-section, can be plugged onto the four supporting bolts from above, the supporting bolts then bearing tightly against the inner wall of the profile.
  • the metal profile carrier 6b serving as a stand is thus held on the frame part 6a arranged on the floor so that it cannot move and rotate. In this construction, the metal profile carrier 6b stands with its end on the metal profile carrier 6a.
  • the metal profile support 6b to be connected which is used as a stand, is provided at its upper end with a recess 14, for example in the form of a bevel or a notch, so that the profile support 6b is inserted laterally between the two horizontal frame parts and then plugged onto the lower four supporting bolts can.
  • the two upper support bolts 13 then lie against the inner wall of the profile carrier 6b. The remaining space is then closed with a spacer 15.
  • the spacer 15 can be formed by a correspondingly Z-shaped tube section, which is initially held loosely in the profile carrier 6b during assembly. After attaching this spacer 15 is pushed up from the fully drawn assembly position to the end position and firmly connected via side screws 15 'to the profile carrier 6b, so that there is an immovable positive connection.
  • the vertical profile carrier 6b is somewhat shorter in length than the clear internal dimension between the lower and upper frame part and can be pivoted sideways into its final position.
  • the remaining free cross section of the attached profile carrier 6b is then filled in via spacers 16, which in this embodiment are essentially U-shaped and have an outwardly bent support nose 17.
  • the carrier can be supported directly on the lower frame part 6a or, as shown, can be arranged at a distance.
  • the spacer 16 is attached to the profile carrier 6b both above and below by one or more screws. The size and number of screws depends on the specified statics.
  • the lower screws 18 can be designed in such a way that they also serve as shear bolts, ie are sheared off if a corresponding change in length of the vertical profile beam 6b occurs due to thermal expansion in the event of a fire. This ensures that the partition does not "bulge” in the event of a fire.
  • the spacers 16 nevertheless hold the vertical profile carrier 6b in a form-fitting manner in its connection.
  • the embodiment C is in turn designed with only two supporting bolts 13 lying next to one another, for example in the form of clamping sleeves.
  • the locking is effected in this embodiment via a full profile piece 16 ', which is raised for assembly and after the stand 6b has been put down falls by its own weight into the end position shown and brings about a reliable positive connection.
  • the upper end can then be locked using one of the forms described above for the spacers.
  • locking by spacers can be omitted at least for the upper end of the stand.
  • the vertical metal profile beams 6b which act as stands, are in turn provided with supporting bolts 13, preferably in the form of clamping sleeves, in accordance with the predetermined division into individual fields, so that the horizontally extending metal profile beams 6c used as bolts, which have a corresponding one at both ends Recess, for example, are provided with an oblique cut, can be placed from above on the projecting ends of the support bolts 13. Since the heavy panes made of fire protection glass are supported on the metal profile supports 6c, an additional locking is not necessary since the weight of the respective fire glass pane lying on them is sufficient.
  • the outer surfaces of the frame parts are provided with a cover made of heat-resistant material, as shown in FIG. 2, through which the horizontally extending bolts are then connected securely.
  • the recess on the horizontally extending metal profile beams 6c can also be in the form of a notch 14 ', as shown in Fig. 3 for the profile piece 6'c.
  • Fig. 5 shows a plan in a larger scale, the design of the support bolts in the form of so-called clamping sleeves.
  • These consist essentially of a slotted spring steel bush with a tapered end for easy hammering.
  • the sleeve has a slightly larger outer diameter than the associated, not reworked hole, so that it is under tension after driving. The slot remains open even when inserted.
