    From AT 411,617 B a fire protection sleeve for the partitioning of od with a pipe. Dg!, Passaged - through openings through Bautrennelemente, such as walls, ceilings od. Like. Of buildings, against fire spread known, the same in the duct opening or in an embodiment provided as a top collar - each with a radially outwardly projecting mounting flange for its attachment to the partitioning element on the fire-prone side is formed and the tube surrounds the circumference.
    This sleeve comprises a cylindrical metal sleeve housing, with at least on one side radially inwardly directed fire protection laminate retaining edge, in which housing a e.g. is arranged with a laminate band spiral formed fire protection laminate body, and wherein the housing body of the housing is formed integrally with its mounting flange and its retaining edge.
    The fire protection sleeve housing is made, for example, from a deep-drawn metal material, in particular from a sheet metal material.
    Maintaining the basic concept just described is, in particular due to many years of practical experience with this type of fire protection sleeve and for reasons of a much more rational and thus less expensive production this known fire sleeve while maintaining the basic concept just described and its structure, also with regard to the basic materials from which it is manufactured, each adapted to the installation situation has been changed.
    Thus, this refined and still fully proven fire protection sleeve today is formed of a thin steel sheet strip, which is e.g. produced by punching and constructed so that one of the two ends has slot openings, in which after closing the band to the housing cylinder, the locking tabs projecting beyond the other end of the band are inserted into said slot openings and bent over there to the outside of the housing.
    The hitherto radially inwardly facing and continuous laminate holder edge is replaced by a plurality of spaced-apart, bent from the housing cylinder sheet metal strip radially inwardly bent over and there projecting and with the steel sheet band integral laminate retaining tabs.
    Instead of one on the other side of the cylinder steel sheet band closed radially outwardly projecting, also continuous mounting flange are now in lesser majority outwardly bent and there protruding individual, also integral with the steel sheet band mounting tabs with mounting holes, especially Langlöchem arranged with their help the
    Fire protection sleeve on a wall, ceiling od. Like. Building element by means of screws od. Like., Fasteners can be mounted.
    It has now been shown in practice that the od either directly in a wall or ceiling passage opening usually partially accommodated, a guided through the aforementioned opening pipe od. Like. Surrounding fire protection collar or set on the fire-prone side in front of the opening Such cuff in any case with its radially outwardly projecting mounting tabs on the heat of any fire that may be exposed, so on the latent fire endangered page on the wall or ceiling by means of fasteners, usually fixed by anchored in the wall or ceiling screws or is anchored.
    Now this side of the wall, partition or ceiling, even if it is now based on concrete, plastic concrete material (Prottelith), foam concrete, formed of Mineralpiatten, such as plasterboard or even wood or wood materials, an actually occurring fire and the exposed to high temperatures of up to 1000 ° C in full extent.
    This leads to a disintegration or destruction of the ceiling or wall construction material and thereby the anchoring of the fire sleeve by means of the guided through the openings of their Monthglaschen fasteners, ie in particular screws, brittle or possibly even dissolved before the fire protection of the cuff is full, a Breakthrough of the fire preventing effect fulfilled.
    There is therefore the greatest risk that the fire sleeve away in the event of fire from their fire propagation-preventive position and there their passage opening with the inflating fire protection safely occlusive function can no longer meet.
    In particular, the assembly of conduits in general, and in particular of drains and the associated fire protection collars, is a problem especially in retrofitting, mainly in ceilings. The choice of the size of e.g. For example, in the case of retrofitting a building as a core bore, the ceiling duct opening has two requirements:
    First, the bore must be so large that e.g. Drainpipes fit with their push-in sleeves through these openings and can be cased later. With fire protection collars fitted, there is often the problem that the bore is too large compared to the collar diameter and therefore the collar can not be mounted because these mounting tabs do not " cover " the core bore. or the mounting tabs can no longer find a corresponding stop, because they attack too close to the edge of the pipe duct opening. The required hole for the attachment of the sleeves is then too close to the core hole and there breaks when introducing the sleeve attachment element, the ceiling material.
    Further, since the cuff does not cover the entire core bore, it is on the risk of fire endangered side of the ceiling to the fact that the fire between penetration wall and cuff can penetrate.
    Furthermore, the space on the ceiling underside and also on a wall, if immediately below or after a change in direction of the pipe takes place, very small.
    For this reason, currently the fire protection collars are often used without appropriate secure attachment to the respective ceiling or wall, which further usually takes place after the laying of the pipes and thus causes an increased installation costs. This has the consequence that the assembly then often just done poorly and may pose a dangerous problem in any Brandfail, since such poorly mounted fire protection sleeve can ultimately solve the ceiling or wall, wandered away from the fire to be protected through opening and so enables a fire breakthrough.
    Thus, a solution has been sought to prevent the problems outlined and the invention is now essentially to provide a true " remodeling construct " the as described above and practice proven
    To completely avoid fire protection sleeve, but still effective to ensure that their place of action does not need to change in case of fire, namely the attachment or anchoring of the previously used, latent fire endangered side of a wall, partition or ceiling to a point of this Bautrennelemente is moved, which is not affected by the fire and the associated high temperatures, so has turned away.
    The invention thus provides a fire protection sleeve for bushings of pipes od. The like. By Bautrennelemente, especially ceilings, false ceilings, partitions or walls, with a formed by a ring-like or cylindrical self-contained sheet metal housing in the interior, preferably with a fire protection laminate tape formed, fire protection body is arranged, which is held with radially inwardly projecting and retaining tabs of the housing sheet metal strip and projecting from one side or from an edge of the housing sheet metal strip a plurality of preferably designed as elongated holes mounting holes mounting tabs or a A plurality of such mounting tabs punched in said housing sheet metal strip and of or
    be bent or bent out of it radially outward, which is characterized in that using the mounting holes of the mounting tabs on the latent fire endangered side or surface of the ceiling or wall arranged fire protection collar each of the mounting tabs via a junction with one of a bendable or flexible, preferably fireproof material, in particular made of metal, made long strip, wire, chain, or rope-like mounting bracket extension member connectable or connected to at least one mounting hole, which od each between the Wandungsaußenseite of guided through the duct opening. Like ., And the eventual the pipe enclosing insulating material and / or filling material and the inner wall of the passage opening to the fire exposure not exposed other side or surface of the ceiling or wall can be guided or guided, to this other side or surface of the Ceiling or wall fitting bendable or umknickbar or bent and by means of one, through the mounting hole or one of their mounting holes od. Like. Guided fastener, in particular screw, to the fire-free side or surface of the ceiling or wall fastened or fastened.
    When using the new fire protection collars, the diameters of the core holes should be so large that they are at least slightly larger (in diameter, for example, up to 10 mm larger) than the outer diameter of the fire protection collar.
    With the new version of the fire protection collars, it is possible, so to speak, by means of an appropriate setting and bending of the mounting bracket extension elements and their installation on the non-fire end of a ceiling a " extension " the previous, relatively short mounting tabs to achieve.
    This means that the pitch diameter for the necessary holes in ceilings od. Like. Can be easily increased significantly. The cuff is placed in the blanket or wall e.g. inserted and attached to the stop of the set or angled mounting bracket extension elements. The attachment of the sleeves can, if desired or necessary, be done before laying the pipes to be performed through the ceiling and thus simplifies the installation of fire protection cuffs quite essential.
    Furthermore, by the stop at the mounting tabs a complete insertion of the cuffs in the passage opening of the wall or ceiling avoided, and thus their proper function is guaranteed in a possible fire, since on the fire danger side from the opening outstanding metal housing can act enough heat and thus a as fast as possible
    Expansion of the intumescent layer-forming agent arranged in the interior thereof, thus e.g. Fire-resistant laminate, is substantially promoted.
    The installation of fire protection sleeves for ceilings or walls that are not accessible from both sides, was previously without increased effort or not solvable.
    The given with the mounting tab extension element new mounting aid is thus an extension arm for the mounting tabs, which has each fire sleeve. This new assembly aid is by means of connecting and fastening element, such as screws, rivets, folding or crimping of sheet metal cuts on the mounting tabs u. Like. Attached.
    The extension element has either a length markings or graduation cuts and can thus be adjusted to the appropriate thickness of the separating component (wall or ceiling) and thus angled in the right place. It preferably has the same way as the mounting tabs of the fire sleeve over one or more holes, so holes that are used for attachment.
    The fire sleeve is inserted with the novel extension element in the existing opening in the ceiling or wall until the sleeve on the other side of the wall or ceiling, for. is flush or protrudes over the entire installation depth of the cuff from the wall or ceiling.
    This also corresponds to the abutment of the extension element which has been set or angled beforehand according to the thickness of the separating component having the respective passage opening. This can be done before or after the pipe assembly.
    Now, under certain circumstances, e.g. In the case of a partition wall, a fire load acts on both sides. For this case - after the insertion of the fire protection sleeve with the help of the new mounting bracket extension element - a second fire protection sleeve on the already accessible side of the wall can be attached.
    This means that the mounting tabs on the accessible wall side to be mounted can be screwed together with the holes or fixing screws of the mounting bracket extension element. Thus, the used on the inaccessible side of a wall fire protection sleeve and the cuff are attached to the accessible side only with a set of extension elements, which means that ultimately only half to perform fixing work for the two fire sleeves, and thus valuable assembly time is saved and Furthermore, the risk of assembly errors is substantially reduced or completely avoided.
    In the case of fire protection collars, which are mounted and fastened to ceiling insulation on the underside of the ceiling, enormous demands are placed on the attachment of the fire protection collar in the event of fire. For ceilings made of lighter materials such as wood, aerated concrete, aerated concrete, Prottelith (mixture of cement and Styrofoam balls) or the like, there is a risk that even the screws on the fire side lose their strength as a result of heat conduction into the interior of the respective partition (ceiling). By the
    In addition, there is usually a loss of heat or burn-off in the immediate vicinity of the screw fastening, even inside the ceiling. Falling off the fire sleeve can then no longer be prevented.
    The new mounting aid tab extension eliminates this problem by having the attachment " above " the ceiling takes place and an immediate effect of temperature on the attachment of the underside of the ceiling arranged fire protection sleeve can no longer come about.
    As for the various particular concrete embodiments of the new and improved fire sleeve, the following variants are preferred in view of the ease of connection between the sleeve mounting brackets and the mounting bracket extension members and their ease of use:
    Each of the mounting bracket extension members for connection to the sleeve mounting tabs may be a first through the mounting slot of the sleeve mounting tab first feasible and then bayonet-like in a closed position transversely to the extension of this oblong hole rotatable, about hahngriffartigen, small rotary lever od. Like ,
    Further, each of the mounting tab extension members may be connectable or connected to the sleeve mounting tab via a rivet or screw-nut connection guided through the mounting holes of the mounting tab and the extension member.
    Ease of use and firm grip of the fire sleeve is ensured when each of the mounting bracket extension elements is connected by means of cross-up and Umbiegebereiche with the sleeve mounting tab via a bayonet-type locking mechanism or connected.
    So it is e.g. provided that each of the mounting tab-Verängerungselemente has transversely to its longitudinal extent two oppositely disposed, pointing in opposite directions with their free ends or end edges, such as hook-like or hook-like effective, ultimately crimped on distance punched, which durchsteckbar through the slot of the mounting tab and protrude on both sides over the opposite straight edges of the slot after appropriate rotation of the mounting strap extension elements.
    Furthermore, it may be provided that each of the mounting tab extension elements with the sleeve mounting tab by bending at least one in the extension mounting tab, for example by punching, preformed by the sleeve mounting hole and lead over the sleeve mounting tab bendable bendable connectable or . connected is. It is advantageous if the elongate, strip-like mounting tab-Verängerungselement has at least one opening or an end-mounting hole for fixing them on the side facing away from the fire side of the ceiling or wall.
    It is also advantageous if the elongated, strip-like mounting tab extension element to adapt to the respective thickness of the
    Implementation opening having wall or ceiling and adapted to the respective mounting situation, a plurality or a series of, preferably equal sized and / or equally spaced, mounting holes has.
    Favoring the bending of the mounting tab extension members and their length adaptation to the respective thickness of the blanket is a variant in which the elongate, strip-like mounting tab extension member comprises a pair or a plurality of pairs of opposing side notches or notches to facilitate the bending the mounting bracket extension member and to adapt to the thickness of the passage opening having wall or ceiling and to the respective mounting situation.
    Further lying in the invention mounting bracket extension elements disclosed in claim 10, according to which it is provided that the mounting bracket extension element by a, preferably refractory, for example mineral fiber tape, such a rope, a chain, a ball chain, a wire od. Like is formed with a connection member to the mounting hole of the mounting tab, possibly node, and one or a fastening ring chain link or loop at the free end or in the vicinity thereof.
