Definitions

  • the invention relates to a fire protection element and a fire protection bandage for sealing a cable wall or ceiling duct, with such a fire protection element.
  • conduit passages with non-refractory pipes or cables in ceilings or walls with a firewall.
  • the firewall is disposed in the conduit passage around the conduits and usually includes an intumescent material which ensures reliable closure of the conduit passage in the event of a fire.
  • Ablative or mineral materials can also be used.
  • mineral wool is used. However, this has the disadvantages that it contains fibers and tends to form dust. Thus, mineral wool is not suitable for places that need to be as free of dust and fibers as possible, such as clean rooms or telecommunications equipment.
  • the object of the invention is therefore to provide an improved fire protection element for fire protection bandages.
  • a fire protection element is provided with a mat of intumescent material, a reinforcing insert and ventilation holes.
  • the reinforcing insert serves to stabilize the intumescent crust created in the event of a fire and helps to prevent them in parts from the fire protection element drops.
  • the ventilation holes are through-holes specially designed for air circulation.
  • the ventilation holes are not capillaries or similar tubular structures with a diameter of a few millimeters, as may occur, for example, in a foamed intumescent material.
  • air can circulate through the fire protection element and remove heat. In this way, for example, the temperature of lines can be reduced, which are covered by the fire protection element, or their increase in temperature can be reduced.
  • the fire protection element may have an upper side and an oppositely arranged lower side.
  • the ventilation holes each extend linearly from the top to the bottom of the fire protection element.
  • the reinforcing insert may extend parallel to the top, thereby uniformly stabilizing the fire protection element, particularly when the reinforcement insert extends substantially over or through the entire fire protection element.
  • the reinforcing insert may be formed by a mesh or a woven fabric and may be made of metal, expanded metal, glass fibers, basalt fibers, carbon fibers or ceramic fibers. A hybrid structure of the reinforcing insert of several materials is possible. The higher temperature resistance compared to the intumescent material is advantageous since the reinforcing insert is not affected by the temperature activating the intumescent material and can thus exert its stabilizing function.
  • the reinforcing insert can be flexible, so that the fire protection element can be easily adapted to different surfaces, so that the fire protection element rests close to the surface. Therefore, the fire protection element is in particular not designed rigidly to allow easy installation, in which no tools for deforming the fire protection element are required.
  • a low elasticity of Reinforcement insert may be advantageous to facilitate assembly and to allow press fits and to improve the stability of the fire protection element.
  • the reinforcing insert can be arranged in the outer surface of the fire protection element or at least partially form the surface of one side of the fire protection element. It is advantageous to position the reinforcing insert in the surface of the fire protection element in order to stabilize the outer surfaces and in this way to keep the intumescent crust which arises in the event of a fire longer on the fire protection element. Furthermore, the reinforcing insert in this way can be easier to machine, in particular cut through, whereby the assembly is facilitated.
  • the reinforcement period may be pressed into the surface of the intumescent material.
  • the vent holes may have a diameter between 5 mm and 50 mm or between 8 mm and 15 mm. Alternatively, the diameter of the ventilation holes may be 10 mm. Preferably, all the ventilation holes have the same diameter in order to ensure homogeneous properties of the fire protection element and to reduce the manufacturing costs. Alternatively, ventilation holes with different diameters can also be provided.
  • the fire protection element may have a hole density between 100 and 5000 ventilation holes / m 2 .
  • the hole density may be between 500 and 3000 vent holes / m 2 or between 1000 and 2000 vent holes / m 2 .
  • the ventilation holes may be distributed substantially homogeneously over the fire protection element.
  • the fire protection element may be provided in the form of endless material and preferably has a thickness of 8 mm to 15 mm, in particular of 10 mm. This means that the fire protection element as a continuous very long band, for example in the form of a roll is provided. This has the advantage that sections of the desired length can be cut off from the strip as required, so that the fire protection element can be installed in one piece without additional trimming and thus waste is minimized.
  • the intumescent material can be mineral-fiber-free, which makes it particularly suitable for locations that need to remain free of dust and fibers, such as clean rooms or telecommunications equipment.
  • a fire protection bandage for sealing a cable wall or ceiling bushing provided with a fire protection element according to the invention to solve the above object.
  • the fire protection bandage can be wound around a cable and / or a cable tray, whereby the outside of the cable and / or the cable tray can be covered.
  • the ventilation holes extend from the cable-side surface inside to the environment-side surface on the outside of the fire protection bandage.
  • the cables or the cable tray are insulated from the environment by the fire protection bandage.
  • air can flow through the ventilation holes and remove heat from the cables or the cable route.
  • the fire protection bandage is not limited to use with cables.
  • the fire protection bandage can also be wound around other types of pipes, such as pipes, with or without wiring. Furthermore, the fire protection bandage can also be wound around several lines and / or cable routes, in particular with different types of lines. Further advantages and features will become apparent from the following description taken in conjunction with the accompanying drawings. In these show:

  • FIG. 1 shows a fire protection element 10 which comprises a mat 12 with a multiplicity of ventilation holes 14 and a reinforcing insert 16.
  • the fire protection element 10 is cuboid and has a length L of 500 mm, a width B of 150 mm and a thickness H of 10 mm (see Figure 2).
  • the fire protection element 10 may have other shapes and dimensions.
  • the width B between 50 mm and 500 mm and / or the thickness H between 8 mm and 15 mm.
  • the fire protection element 10 may be provided as a continuous material, in particular as a very long band in the form of a roll, whereby the possible length L is limited essentially only by the length of the tape
  • the mat 12 is at least partially made of an intumescent material and is substantially fiber-free.
  • the mat 12 has no mineral fibers.
  • the reinforcing insert 16 is a mesh of metal wire.
  • the reinforcing insert 16 may be formed by a mesh or fabric of metal, expanded metal, glass fibers, basalt fibers, carbon fibers or ceramic fibers.
  • a hybrid structure of the reinforcing insert 16 of several materials is possible. However, preference is given to materials which are fiber-free or have no unbound fibers and are therefore particularly suitable for clean rooms which must not be contaminated by free fibers.
  • the top 18 is formed by the reinforcing insert 16, which extends parallel to the surface of the mat 12.
  • the reinforcing insert 16 is close to the mat 12 and is beispieiswetse by means of an adhesive attached to the mat 12. Additionally or alternatively, the reinforcing insert 16 can be pressed into the surface of the mat 12 or completely or partially in this - 8th -
  • the reinforcing insert 16 can be introduced directly into the production of the mat 12 in this.
  • the reinforcing insert 16 extends substantially over the entire width B and length L of the fire protection element 10.
  • the reinforcing insert 16 can be made wider than the width B and thus unilaterally or bilaterally form a projection (not shown), for example, during assembly for Fixing the fire protection element 10 may be used or is bent over the sides of the fire protection element 10, in order to stabilize them in particular in case of fire.
  • the ventilation holes 14 each have a diameter D of 10 mm and are distributed over the fire protection element 10 in the form of an equidistant grid.
  • the vent holes 14 may have a diameter D between 5mm and 50mm, or preferably between 8mm and 15mm.
  • ventilation holes 14 with different diameters D can be provided.
  • the ventilation holes 14 may be distributed as desired over the fire protection element 10, wherein a homogeneous distribution is advantageous in order to ensure uniform properties over the entire fire protection element 10.
  • the mat 12 has a hole roofs of about 2500 ventilation holes m 2 .
  • the hole density can be between 100 and 5000 ventilation holes / m 2 , preferably between 500 and 3000 ventilation holes / m 2 , preferably between 1000 and 2000 ventilation holes / m 2 .
  • the ventilation holes 14 extend linearly from the upper side 18 to the lower side 20 through the fire protection element 10 (see FIG. 2).
  • special openings can be provided in the reinforcing insert 16, in particular if the reinforcing insert 16 has a mesh width which is smaller than the diameter D of the ventilation holes 14, or the reinforcing insert 16 covers a large part, for example more than 50%, of the cross-sectional area of all the ventilation holes 14 ,
  • sufficient ventilation holes 14 provide a substantially free cross-section over the entire thickness H, in order to ensure sufficient air circulation for the heat transfer.
  • part of the Cross-sectional area of a small part of the ventilation holes 14 may be hidden by the reinforcing insert 16, without thereby the Heilzirkuta ion of the fire protection element 10 is substantially impaired.
  • the ventilation holes 14 have a circular cross-section and are therefore particularly inexpensive to produce.
  • the ventilation holes 14 may have an arbitrary cross section, in particular also a cross section which changes over the thickness H.
  • the vent holes 14 extend perpendicular to the top 18 through the mat 12 and form a circular cylindrical through hole due to their circular cross-section. Alternatively, at least a portion of the vent holes 14 may extend at an angle through the mat 12 that deviates from 90 °.
