Definitions

  • the object of the present invention is to overcome this defeet.
  • the characteristic feature of the invention is that in the said gap beneath the joint there is laid a tube of flexible material, filled with air, so that the tube walls on both sides of the joint are pressed sealingly against the slab-shaped building elements, to prevent any material being forced into and filling the said gap. There can thus be no filling up of the joint with mortar to affect sound insulation, so that sound insulation is very satisfactory in the composite building elements.
  • This method also makes the seaming of the concrete-building elements considerably cheaper than with previously used methods wherein the gap was filled to the upper surface of the slab by a soft material, such as mineral wool or foam.
  • the invention also relates to a specific form of the tube used in this method.
  • FIGS. 4 and are cross sections through two different embodiments of tubes for use in this method.
  • the concrete-building elements 1 and 2 shown in the drawings each consist of a concrete coffer 3 reinforced by strengthening bars (not shown) and a superimposed flat concrete slab 4, also reinforced by strengthening bars (not shown).
  • a sound barrier 6 is disposed in the gap 5 between these two elements 3 and 4.
  • this barrier consists of wedges of neoprene or other suitable istrophic and flexible plastic or rubber, superimposed in pairs and axially movable relative to each other to vary their total thickness, these pairs of wedges being laid at equal distances on the upper edge 7 of the concrete coffer 3.
  • the wedges are so chosen and located, and the elasticity of the wedge material is such, that with an increase in the load on the concrete slab by e.g. 50 kg., the wedges are compressed by about 0.2-0.5 mm. Very effective sound-damping values are produced by such a construction.
  • a layer 9 of mineral wool or similar heatand sound-absorbing material is applied in the cavity 8 in the interior of the concrete coffer 3.
  • the composite concrete-building elements I, 2 are factory made so that they all have the same thickness. Before being sent to the building site, the building elements preferably have their upper part covered by a protective plastic foil 10 (FIG. 2), so that the gap 5 between the concrete coffer 3 and the concrete slab 4 is completely closed.
  • a protective plastic foil 10 FIG. 2
  • the air in the tube 14 is let out, so that the tube collapses and lies flat on the top 7 of the concrete coffer 3. If so desired, the tube 14 can then be withdrawn and reused in further seams between concrete building elements 1, 2.
  • the tube 14 can with advantage have a channel-shaped longitudinal expanded portion 19 or a head which when the tube is applied enters the gap 12 between the concrete coffers 3 and thus centers the tube in its correct position immediately below the seam joint between the concrete slabs 4.
  • longitudinal reinforcing filaments or wires 21 in its two diametrally opposite fins 20.
  • Similar reinforcing filaments or wires 22 should also be embedded in the longitudinal edge portions 23 of the tube whereat the channel-shaped widened portion 19 joins the head portion of the tube I4.
  • a method of assembling supporting structures comprising a number of adjacently disposed composite concrete-building elements each consisting of a preferably coffer-shaped first concrete support element, a vertically spaced superimposed slablike second concrete element and sound insulation means disposed in the horizontal gap between said first and second concrete elements, wherein after these composite-concretebuilding elements have been laid on a support portions of the composite concrete-building elements are spaced apart forming a vertical gap, the vertical gap between adjacent composite concrete-building elements is filled with mortar or similar material to bond together these composite concretebuilding elements, wherein the improvement comprises placing in the said, horizontal gap at the joint between the superimposed composite concrete-building elements a tube of flexible material, filled with air, so that the tube walls lie on both sides of the joint and are pressed sealingly against the building elements to prevent any mortar from the vertical gap being forced into and filling the said horizontal gap.
