    SIMPLE SCREW FIXING OF A FIRE PROTECTION SLEEVE AROUND PIPE ENTRIES WITHOUT ANY TOOLS
    In order to prevent the spread of flames and dangerous gases in the event of fire, line bushings in walls and ceilings are provided with preventive fire protection measures. Most commonly used are fire protection collars, which are placed around a cable duct and attached to the wall or ceiling. According to the state of the art, the fire protection collar is fastened to a solid wall or ceiling using a combination of dowels and screws or by mortaring in the bent fastening straps. Fixing the fire protection collar to a soft bulkhead system is particularly cumbersome. According to the state of the art, the fire protection collar must be fixed to the mineral fiber board with several threaded rods so that the installed fire protection system fulfills the required fire resistance class. The resulting considerable time and material expenditure for the installation of the fire protection represents a relevant problem for the trades. Current publications on the subject describe new fasteners for soft bulkheads, such as the use of a spiral screw or a hinged spring anchor. This type of fixation of a fire protection collar can reduce the time required, but not the material and cost expenditure.
    The specified in protection claim 1 invention is based on the requirement to generate the fixation of a fire protection collar around a cable bushing that prevents the cable bushing from slipping in the event of a fire and its installation in one step with a commercially available chipboard or wood construction screw, such as ASSY® Würth screws on a soft partition wall or soft partition ceiling, or with a concrete screw without dowels, e.g. concrete screw with hexagon head W-BS / S (160 mm) or with the concrete screw hexagon head and large washer W-BS / S (180 mm ) of the Würth company can be carried out on a light partition wall, a solid wall or solid ceiling, so that the work and material expenditure for the trades is minimized.
    These requirements are met with the features listed in claim 1 protection.
    With the invention, the slipping and falling out of the cable bushing is prevented in the event of a fire. In addition, the uncomplicated screw fixing of a fire protection collar around cable penetrations on soft partition walls, soft partition ceilings, lightweight partition walls, solid walls and ceilings is cost-effective and user-friendly.
    [0005] Advantageous embodiments of the invention are specified in claims 2 to 4.
    [0006] Embodiments of the invention are explained below with reference to FIG. 1 and FIG. 2. These show:
    Fig. 1 is a cross-sectional view of a wall with a line bushing through a soft bulkhead system with a mineral fiber board.
    Fig. 1 shows a cross-sectional view of a wall 1, such as a single-panel soft partition wall. A cable bushing 2 runs through the soft partition wall and consists of a combustible material such as PVC-U, PE-HD or PP-HT with or without insulation or is designed as a multi-layer composite pipe with combustible insulation, for example synthetic rubber insulation is. The line bushing 2 is surrounded on the inside of the soft partition wall with a fire protection sleeve 3. The fire protection collar 3 is attached to the mineral fiber board 6 with coarse-threaded chipboard or wood construction screws 4, such as the ASSY® screw from Würth. The resulting spaces between the mineral fiber board 6 and the cable bushing 2 are covered with a filler 5
    closed.
    2 shows a cross-sectional view of a solid ceiling with a screw fixing of a fire protection collar around a line bushing.
    Fig. 2 shows a cross-sectional view of a solid ceiling 7, such as an aerated concrete ceiling. A cable bushing 2 runs through the solid ceiling 7 and consists of a combustible material such as PVC-U, PE-HD or PP-HT with or without insulation or is designed as a multi-layer composite pipe with combustible insulation, for example synthetic rubber insulation. The cable bushing 2 is surrounded by a fire protection collar 3 on the inside of the solid ceiling. The fire protection sleeve 3 is with concrete screws without dowels 8, such as. B. the concrete screw with hexagonal head W-BS / S (160 mm) or with the concrete screw hexagonal head and large washer W-BS / S (180 mm) from the company Würth attached to the solid ceiling 7. The resulting spaces between the solid ceiling 7 and the cable bushing 2 are sealed with a filler compound 5.
    With the screw fixation according to the invention of the fire protection collar 3 to a line bushing 2 on a soft bulkhead wall 1 with a commercially available chipboard or. Wood construction screw 4 and on light partition walls, solid walls or solid ceilings 7 with a commercially available concrete screw without dowel 8, the cable bushing is prevented from slipping and falling out in the event of a fire. The simple screw fixing of a fire protection collar 3 around line bushings 2 without tools on the aforementioned walls and on solid ceilings 7 is inexpensive and user-friendly.
