Definitions

  • the invention relates to a device for connecting adjacently arranged insulating elements, in particular made of mineral fibers, consisting of a web with two substantially parallel longitudinal edges and at the first longitudinal edge of the web in opposite directions extending, substantially perpendicular to the web extending holding elements and at least a, arranged on the second longitudinal edge of the web support element, which is aligned parallel to the holding elements extending.
  • the invention further relates to an insulation system for the sound insulation of closed and / or access having open spaces with at least one traffic route, in particular traffic tunnels, garages, stations or the like, consisting of at least two, in particular plate-shaped insulating elements, preferably of mineral fibers, which are arranged adjacent to each other such that their narrow sides abut each other.
  • Tunnels are underground passages for traffic routes and are created for traffic with motor vehicles and rail vehicles. As far as the tunnels are laid out at shallow depths, they are formed with rectangular cross-sections, whereas tunnels which cross mountains or are led underwater are formed for static reasons with a vault and with curved side surfaces, in particular with circular cross-sections. Road tunnels, because of the widths of the roads, the emergency parking bays and other escape routes, usually have larger cross sections than the tunnels intended for rail traffic.
  • the walls are made of reinforced concrete or, initially, of cast-iron tubbing, in which concrete structures are installed.
  • Ceilings of underground subways often consist of steel girders on which concrete floors and immediately adjacent roadway structures are laid.
  • the vehicles in the tunnels particularly heavy trucks or trains, induce vibrations in the construction elements of the tunnel and in the adjacent soil. This results in a high noise pollution.
  • the emitted noise in the form of airborne noise not only leads to considerable annoyance of the passengers in the area of the stops, but also to excessive noise emissions at the entrances and exits of tunnels, in the vicinity of air ducts, exits of stations and other outlets or too thin overlaps.
  • insulating materials are particularly effective when placed near the sound sources.
  • suitable sound-absorbing insulation materials If flammable materials, in particular absorbers burning off under intense development of smoke, are eliminated from the outset because of the associated risks. These include, for example, plastic foams and rigid foams. Due to their open, finely porous structure, mineral wool insulating materials, especially in the medium and high frequency ranges, are very effective sound absorbers.

  • the rockwool insulation materials produced similarly to the glass wool fibers are free of non-fibrous particles, which must be taken into account when comparing the bulk densities and binder contents.
  • Rockwool insulation materials produced with the aid of cascade fiberizing machines are generally bound with not more than about 4.5% by weight of organic binders, while the binder contents in rockwool insulation materials produced by the jet-blown process are about 2% are up to about 4% by mass higher.
  • the non-fibrous particles are usually not covered by the binders, so that they serve primarily the binding of the fibers.
  • thermosetting resins are used as binders, especially mixtures of phenol, formaldehyde and urea resins. These resins are soluble in water and have a generally accepted value for money.
  • Hydrophobizing substances such as mineral oils, silicone oils and other additives, which are usually present in proportions of about 0.2 to about 0.3% by mass with respect to the net fiber mass or to the fiber mass plus the non-fibrous constituents, apply not as a binder.
  • These substances distributed in thin films on the fiber surfaces develop a certain binding capacity for the smallest particles, such as fiber fragments, so that they are sometimes referred to as dust binders.
  • the interfacial forces caused by these substances are so low that they have no significance for the mechanical strength of the insulating molded body.
  • the fibers produced by means of cascade fiberising machines are intrinsically deformed and become entangled with one another immediately after their formation into fiber flakes, the fibers impregnated with binders and additives frequently forming the central regions of these fiber flakes.
  • the fiber flakes are collected at the end of a collection chamber as a primary impregnated fiber web and then deposited by means of a shuttle device across a second slower-moving conveyor.

Thin, consisting of relatively brittle glass fibers Wirrvliese can still be separated with a relatively sharp cutting edge. For fabrics, especially woven fabrics made of plastic fibers, a shearing separation is frequently observed, which leads to fraying edges of the laminations.
