Definitions

  • the present invention relates to a fire-protected penetration of a conduit in a wall or the like as well as a method of providing such a penetration.
  • conduit means a pipe, a cable, a duct or the like.
  • SE, C2 , 509,458 discloses a fireproofing in a plaster board wall, in which use is made of two fireproof rock wool boards of moulded rock wool having a very high density, preferably at least 200 kg/m 3 . These boards have a thickness approximately corresponding to that of the respective plaster board sides and are arranged in a hole which is made in the wall and is aligned with the associ- ated board side and are provided with cut-out or sawn-out openings for the cables or pipes which are to be passed through the wall .
  • One object of the present invention is to provide fire-protected conduit penetrations, which are simple, cheap and safe and easy to mount.
  • the conduit insulation can be easier to handle and apply and, for instance, at least partially consist of glass wool, which normally has a significantly lower degree of fire-retardancy than rock wool .
  • the fire-retardant , compressible mineral wool it preferably consists of rock wool having an original density of suitably at least about 70 kg/m 3 , however advantageously at least about 100 kg/m 3 and preferably at least about 130 kg/m 3 . It has been found particularly advantageous to use rock wool having a density of at least about 150 kg/m 3 .
  • the density should not, however, be too high, as this may have a detrimental effect on the compressibility. It may be preferable that the density is not higher than about 180 kg/m 3 . It goes without saying that in this connection the binder content must be taken into account, so that the mineral wool has the desired degree of compressibility.
  • the fire-retardant , compressible mineral wool can advantageously have a low binder content and be of so- called wired mat type (but without wiring) .
  • the compressible mineral wool is suitably packed so that, after the application of the conduit insulation, the remaining hole space is filled with compressible mineral wool, whereupon the latter is radially compressed and the thus forming free space is filled with additional compressible mineral wool, after which this procedure is repeated the number of times required until the desired degree of radial compression is obtained.
  • a simple, insertable, flat tool such as a trowel or the like.
  • the compressed mineral wool should surround the conduit insulation on all sides with a radial thickness, i.e. substantially perpendicularly to the direction of the conduit, of at least about 5 cm.
  • the compressible mineral wool should be packed in the inner, intermediate part of the hole, the respective hole openings around the conduit insulation suitably being filled and sealed with filling material, which can be fire-protecting in itself, such as mortar of plaster.
  • conduit insulation use is advantageously made of different kinds of pipe insulation sections or the like. They can thus be made of glass wool with its accompanying advantages .
  • the insulation has a central part (suitably the part which co-operates with the compressed mineral wool) of comparatively more fire-retardant mineral wool, such as rock wool, whereas the respective adjoining side parts are of comparatively less fire-retardant mineral wool, such as glass wool.
  • conduit insulation still cover the conduit a distance away from the wall, typically at least about 5 cm.
  • Fig. 1 is a schematic partial perspective view of a section of a conventional plaster board stud wall provided with a fire-protected pipe penetration according to an embodiment of the present invention.
  • Fig. 2 is a view of the same type as the one in Fig. 1 illustrating another embodiment of the present invention.
  • Fig. 3 is a view of the same type as the one in Fig. 1 but illustrating an embodiment of the present invention in a massive wall.
  • Fig. 4 is a view of the same type as the one in Fig. 3 illustrating an embodiment of the present invention which is similar to the one in Fig. 2.
  • Fig. 5 finally, is a view of the same type as the one in Fig. 1 but illustrating an embodiment of the present invention with a plurality of pipes in one and the same penetration.
  • Fig. 1 schematically shows a section of a conventional plaster board stud wall which is provided with a fire-protected pipe penetration according to an embodiment of the invention.
  • the wall 1 On each side, the wall 1 has in conventional manner two superposed plaster boards 2, 3 and 4, 5, respectively.
  • the plaster boards are placed on wall studs (not shown) which keep the two inner plaster boards 3, 4 at a fixed stud distance from each other.
  • a through hole having quadrangular cross-section is made in the wall . Part of one side opening of the hole is indicated in the Figure by the line 6, 7, 8.
  • a quadrangular frame or abutment construction 9 is arranged, which closes the inner open space between the plaster boards 3, 4 around the hole.
  • the construction 9 consists of a U-like girder element, so-called nogging pieces, having a width corresponding to that of the studs, i.e. the distance between the boards 3, 4.
  • the plane abutment sides of the girder elements are on a level with the hole-defining faces of the plaster boards, such as the faces 10, 11 on all four sides.
  • a metallic pipe 13 is passed axially and centrally through the hole in the wall.
  • a pipe insulation extending through the hole is arranged in the form of a conventional pipe insulation section 15 made of glass wool.
  • the cylindrical pipe insulation section can typically have a density of about 70 kg/m 3 .
  • the space between the abutments 9 and the corresponding part of the pipe insulation section 15 is filled with packed rock wool 17.
  • the rock wool is packed around the pipe insulation section such that it is radially very much compressed, so as to be able to expand, if needed, radially inwards towards the pipe insulation section and the pipe to compensate, for instance, for a collapse of the pipe insulation section, if the latter is exposed to such a high temperature that the glass wool softens and "settles" .
  • the rock wool suitably consists of wool of so-called wired mat quality (without wiring) .
  • the wool can typi- cally have an original density of about 100 to about 150 kg/m 3 and be compressed after packing to at least about 50 % of its original thickness.
  • the two side openings of the hole in the wall i.e. in the shown example the hole parts which are defined by the actual plaster boards, are filled with after-filling or after-repairing material 19, which suitably contributes to the fire protection.
  • the material is advantageously mortar of plaster or the like.
  • a penetration of the above-described type can be made in an easy and safe manner by various fitters, in particular insulation fitters. A typical method thereof is described below.
  • the tool suitably consists of a thin, flat element, for instance a trowel, which can easily be inserted axially adjacent to the abutments 9 and then pressed radially inwards, so that a free space forms, which is then filled with rock wool. This is repeated, suitably successively around and along the wall of the hole, until the required radial compression is obtained.
  • the radial compression in itself will ensure a tendency to radial expansion, inwards as well as outwards, thus ensuring that no leakage or slits remain in the fireproofing.
  • the packed, compressed rock wool everywhere around the pipe has a certain minimum radial thickness of typically at least about 5 cm.
  • Fig. 2 illustrates a modification of the penetration according to Fig. 1, in which modification the pipe insulation does not constitute a continuous pipe insulation section of uniform composition.
  • the pipe insulation com- prises a central part 21 which is more fire-retardant in the form of an adjustment member of a rock wool pipe insulation section.
  • the adjustment member typically has a density of about 150 kg/m 3 and a metal coating in the form of a surface foil 22 of aluminium.
  • Pipe insulation sections 23, 24 having the same outer diameter as the adjustment member but made of conventional glass wool are joined to the adjustment member 21 on each side of the same.
  • the pipe insulation sections 23, 24 also have a metal coating in the form of a surface foil 25 and 26, respectively, of aluminium.
  • the joints between the pipe insulation section pieces can, if desired, be taped.
  • the outer packed rock wool 17 corresponds to the description in connection with Fig. 1.
  • the adjustment member 21 is shown with an axial length corresponding to the axial width of the abutments 9. It will, however, be understood that the length of the adjustment member can be varied depending on the wall type and fire protection classification.
  • Fig. 3 illustrates an embodiment of the present invention, which corresponds to that shown in Fig. 1 as concerns the pipe insulation and the packed rock wool.
  • the actual wall 31 is a homogeneous, massive wall, for instance, made of concrete, lightweight concrete, brick or the like.
  • the hole in the wall, whose opening circumference is indicated at 33, is suitably circular in cross-section.
  • Fig. 4 illustrates yet another embodiment of the present invention, which corresponds to that shown in Fig. 2 as concerns the pipe insulation and the packed rock wool, but in this case the wall 41 and the hole 43 in the wall correspond to that shown in Fig. 3.
  • Fig. 5 illustrates an embodiment of the present invention, which is based on the one shown in Fig.
