Definitions

  • the present invention relates to a prefabricated module, particularly for use in the building industry, according to the preamble of claim 1.
  • a prefabricated module is for example known from EP-A-0 061 100.
  • the module comprises three-dimensional wire structure comprising a series of plane nettings, which are spaced apart a pre-determined distance by a series of cross wires welded to the nettings. All plane nettings have substantially the same form and comprise a plurality of pairs of lengthwise wires and a plurality of brace wires.
  • the plurality of pairs of lengthwise wires comprises first, second and third pairs, of which a first pair forms the outer pair of lengthwise wires. The second pair is positioned inwardly with respect to the first pair and the third pair is positioned inwardly from the second pair, so further inwards than the second pair.
  • the second and third pairs of lengthwise wires define spaces on both sides in which panels in insulating material are placed.
  • a prefabricated module is achieved having a filling space between the panels, which can be filled with a filler material such as for example concrete.
  • the prefabricated module is used in the building industry for constructing walls, ceilings, floors or roofs of buildings. To this end, a plurality of prefabricated modules are mounted on the building site so as to form the general structure of the building, after which the filling space is filled with the filler material and the outer sides of the prefabricated module are covered with for example a plastering material.
  • the prefabricated module comprises the technical characteristics of the characterising part of the first claim.
  • the prefabricated module according to the invention comprises a three-dimensional wire structure of welded steel wires which supports a plurality of panels in insulating material on either side. Between the panels, a filling space is provided for introducing a filler material.
  • the wire structure comprises a series of plane nettings, which are spaced apart by a series of cross wires welded to the nettings.
  • Each plane netting comprises a plurality of pairs of lengthwise wires and a plurality of brace wires welded to the lengthwise wires.
  • the plurality of lengthwise wires comprises at least a first pair and a second pair, the first pair forming an outer pair of lengthwise wires and the second pair being positioned inwardly from the first pair.
  • the panels in insulating material are supported in spaces between the first and second pairs on either side of the prefabricated module.
  • the panels of the module of the invention are supported between the outer pairs of lengthwise wires and the next pairs of lengthwise wires.
  • the outer pairs of lengthwise wires and consequently also the cross wires of the module are located adjacent the panels.
  • the outer pairs of lengthwise wires and consequently also the cross wires on both sides of the module are spaced apart from the panels, as these are supported between the second and third pairs of lengthwise wires.
  • the outer lengthwise wires and the cross wires although covered with for example plastering, can vibrate as in response to sounds produced in the vicinity. It has been found that the plastering provides substantially no dampening effect to the vibrations of the wires. The vibrations created on one side of the module are transported via the brace wires of the nettings to the outer lengthwise wires and the cross wires on the other side of the module.
  • the outer wires on the other side of the module resonate with the outer wires on the one side of the module, so that a large amount of sound can be transported through the module.
  • the resonance effect can be compared to the resonance effect between strings of a musical instrument, the filling space between the modules acting as the sound box of the instrument.
  • the outer wires on both sides of the module are located adjacent the panels in insulating material, which provide more of a dampening effect to the wires as compared to for example plastering. Furthermore, it has been found that the introduction of filling material into the filling space between the panels causes the panels to be pressed against the outer wires, so that substantially all outer wires, i.e. substantially all outer pairs of lengthwise wires and substantially all cross wires of the module contact the panels after the filling space has been filled. This can lead to a substantial reduction in the sound conductivity of the module of the invention.
  • the first and second pairs of lengthwise wires comprise right-hand and left-hand first and second lengthwise wires, the first right-hand lengthwise wires being spaced from the second right-hand lengthwise wires by a right-hand distance and the first left-hand lengthwise wires being spaced from the second left-hand lengthwise wires by a left-hand distance, the right-hand distance being larger than the left-hand distance.
  • the panels on the right-hand side are wider than those on the left-hand side of this preferred embodiment of the module of the invention.
  • this difference in width of the panels on one side with respect to those on the other side can further reduce the sound conductivity of the prefabricated module of the invention.
  • the difference in width is a ratio of about 1.5, but it may also be more or less.
  • Figure 1 shows a first preferred embodiment of the prefabricated module of the invention.
  • Figure 2 shows a second preferred embodiment of the prefabricated module of the invention.
  • the prefabricated modules 10, 20 of figures 1 and 2 comprise a three-dimensional wire structure 11 formed by welded wires, and flat elements 12-1/2 made from insulating and/or heat-insulating material, held on either side of the three-dimensional wire structure 11 in such a way as to form a substantially continuous panel.
  • a module 10, 20 may be used either in vertical position as shown in the figures, in horizontal position or in a slanting position, i.e. the module 10, 20 may be used for walls, ceilings, floors and roofs of buildings.
  • the three-dimensional wire structure 11 comprises a series of substantially identical nettings 16, each of which is substantially planar.
  • the nettings 16 are arranged facing one another and are firmly held in their positions by two series of cross wires 18, located on either side of the module 10, 20.
  • Each netting 16 is comprises a plurality of lengthwise wire pairs: a first pair 21-1 and 21-2, a second pair 22-1 and 22-2 and a third pair 23-1 and 23-2. These lengthwise wires are welded to and held in position by a plurality of brace wires 25.
  • the two wires 21-1, 21-2 are the outermost wires in the nettings 16, and the spacing therebetween determines the thickness T of the module 10.
  • the two wires 22-1 and 22-2 are located inwardly from the wires 21-1 and 21-2 and the two wires 23-1 and 23-2 are located inwardly from the two wires 22-1 and 22-2.
  • the two wires 23-1 and 23-2 are the innermost lengthwise wires of the module 10, but further lengthwise wires (not shown) may be welded to the brace wires 25 inwardly from the wires 23-1 and 23-2.
  • the complete wire structure 11 of the module 10, 20 is obtained by welding the cross wires 18 to the outermost lengthwise wires 21-1, 21-2.
  • Particularly efficient methods for making the three-dimensional wire structure 11 comprising lengthwise wires, brace wires and cross wires are amongst others described in US-A-4 667 707, EP-A-162 183 and more recently in the international patent application with no. PCT/EP01/14852.
  • the wire structure 11 may however also be constructed in any other way known to the person skilled in the art.
  • the modules 10, 20 of figures 1 and 2 are parallelepiped shaped, with the lengthwise wires 21-1/2 to 23-1/2 substantially at right angles to the brace wires 25, so that the nettings 16 are substantially rectangular in shape, and the cross wires 18 substantially at right angles to the nettings 16. The angles between the wires may however vary.
  • the modules 10, 20 of figures 1 and 2 are substantially straight, but the modules 10 may also have a bent or arched shape or any other shape known to the person skilled in the art. Openings (not shown) may be provided in the modules 10 for providing spaces for doors or windows or the like.
  • the brace wires 25 of the plane nettings 16 are spaced apart by a first predetermined distance D1
  • the plane nettings 16 are spaced apart by a second predetermined distance D2
  • the cross wires 18 are spaced apart by a third predetermined distance D3.
  • the first predetermined distance D1 is preferably substantially twice the third predetermined distance D3. In this way, a three-dimensional wire structure 11 is achieved which has a regular structure.
  • the distances D1, D2 and D3 may however also vary.
  • the lengthwise wires 21-1/2 to 23-1/2 of the plane nettings 16 are spaced apart by one or more times a fourth predetermined distance D4.
  • the distance between the lengthwise wires 22-1 and 23-1 and the distance between the lengthwise wires 22-2 and 23-2 is each time once the fourth predetermined distance D4.
  • the distance D5 between the lengthwise wires 21-1 and 22-1 and the distance D6 between the lengthwise wires 21-2 and 22-2 is each time a plural of the fourth predetermined distance D4.
  • the distance D6 is substantially equal to D5 whereas in the module 20 of figure 2 the distance D6 is substantially 1.5 times the distance D5.
  • the distances between each two lengthwise wires may however also be chosen differently as desired by the person skilled in the art.
  • all these distances are a plural of 0.5 cm, the dimensions of the module 10 are easily adaptable to the requirements of the building construction by simply varying the plurals of 0.5 cm. It should however be clear that the distances may be varied further.
  • the three-dimensional wire structures 11 carry a plurality of panels 12-1/2 in an insulating material, preferably expanded polystyrene. These panels 12-1/2 are held on either side of the wire structure 11 between the first and second pairs of lengthwise wires 21-1/2 and 22-1/2 and have a width substantially equal to the distances D5 and D6 therebetween, so that they are supported by the lengthwise wires. More particularly, the panels 12-1 are held between the lengthwise wires 21-1 and 22-1 and have a width substantially equal to the distance D5 between these two wires. The panels 12-2 are held between the lengthwise wires 21-2 and 22-2 and have a width substantially equal to the distance D6 between these two wires.
  • the panels 12-1/2 on both sides have a height substantially equal to the distance D1 between the brace wires 25, so that the panels 12-1 together and 12-2 together form a substantially continuous panel on either side of the module 10, 20.
  • the space between the panels 12-1 and 12-2 is provided for introducing a filler material 13, such as for example concrete.
  • the wires 22-1/2, 23-1/2 and 25 located within the filling space between the panels 12-1 and 12-2 form a reinforcement for the filler material 13.
  • the prefabricated modules 10, 20 of figures 1 and 2 are provided for use in the building industry in a similar way as those described in EP-A-180 667 and US-A-4 864 792. Therefore, the use of the modules 10, 20 in the building industry will not be repeated here in detail.
  • the panels are supported between the outer lengthwise wires 21-1/2 and the next lengthwise wires 22-1/2.
  • the outer lengthwise wires 21-1/2 and consequently also the cross wires 18, which are welded to the outer lengthwise wires 21-1/2 are located adjacent the panels 12-1/2. It has been found that this construction reduces the sound conductivity of the modules 10, 20, since the panels 12-1/2 in insulating material have more of a dampening effect to the outer wires as compared to for example plastering (not shown), which is applied on the outer wires as covering material.
  • the panels 12-2 on the right-hand side are wider than the panels 12-1 on the left-hand side. Surprisingly, it has been found that this difference in width of the panels 12-1 on one side with respect to the panels 12-2 on the other side can further reduce the sound conductivity of the prefabricated module 20 of figure 2 with respect to that of figure 1.
