Definitions

  • the invention relates to a self-supporting composite panel for raised floors, ceilings or the like with a trough-shaped outer reinforcement made of sheet metal, preferably sheet steel and a curable, mineral filler to be introduced into this reinforcement in the flowable state, e.g. Anhydrite, the composite effect between the hardened filler and the trough-shaped reinforcement being produced by openings (punctures) provided in the bottom and side walls thereof with inwardly protruding, frayed edges, and furthermore the trough-shaped reinforcement on the outside with a leakage of the filler is covered by the layer preventing breakthroughs.
  • a trough-shaped outer reinforcement made of sheet metal, preferably sheet steel and a curable, mineral filler to be introduced into this reinforcement in the flowable state, e.g. Anhydrite
  • the composite effect between the hardened filler and the trough-shaped reinforcement being produced by openings (punctures) provided in the bottom and side walls thereof with inwardly protruding, frayed edges, and further
  • the object of the invention is to simplify the sealing of the breakthroughs acting as thrust anchors in the trough-shaped reinforcement with respect to the liquid mineral filler and at the same time to significantly increase the strength and bending stiffness of the finished composite panel and thus its load-bearing capacity.
  • the object is achieved in that the leakage of the mineral filler, for example anhydrite-preventing layer consists of a liquid or plastic applied and then cured surface protection and / or finishing agent, which as a closed skin with a correspondingly small clear diameter closes in a trough-shaped reinforcement in a number of openings (punches) made similar to a grater.
  • This method of sealing the openings (punctures) requires a surface protection or finishing agent with a corresponding viscosity and a clear diameter of the openings (punches) of only a few millimeters.
  • the basis of the invention is two new findings, the combination of which results in a surprising rationalization in production and at the same time an extremely significant increase in the load-bearing capacity.
  • the first new finding is that the magnitude of the thrust that is transmitted by the "punches" from the tub floor to the filled pressure-resistant filler depends on the sum of all surfaces that protrude from the tub bottom into the pressure-resistant filler. So the greater the sum of these edge-side surfaces of the punches, the greater the transmitted thrust before the filling material tears off the tub floor. A very large number of small punches can thus transmit a significantly higher thrust than a small number of large punches, while on the other hand the weakening of the floor and thus the reduction in tensile force in the floor does not increase to the same extent.
  • the second finding is that small openings (punctures) can be closed efficiently by a protective layer that serves to protect against corrosion or to improve the surface of the tub material.
  • the invention therefore consists in the combination of the two new findings.
  • the tub bottom is not provided with a relatively small number of large openings (punches) as in the prior art, but rather with a number of openings with a small clear diameter which is several times as large, and then a skin is applied liquid or plastically and this skin is left harden before the mineral filler, e.g. Anhydrite, is introduced. This prevents the liquid filled curable mineral filler from leaking through the openings (punctures).
  • the skin that closes the openings is formed by a quick-drying lacquer that contains a filler made of e.g. Contains pieces of fiber.
  • a filler made of e.g. Contains pieces of fiber.
  • the skin that closes the openings can be a zinc skin.
  • This zinc skin can e.g. by spraying on a zinc dust paint or by hot-dip galvanizing the trough-shaped reinforcement from sheet steel.
  • trough-shaped outer reinforcement 11 made of, for example, sheet steel and a hardenable mineral filler 12, for example anhydrite, which is introduced into the trough-shaped reinforcement 11 in the liquid state.
  • the required composite effect between the hardened filler 12 and the trough-shaped reinforcement 11 is achieved by means of numerous openings 13 (punctures) which have frayed edges 14 which protrude inwards. This through Fractures 13 are generated by means of pointed mandrels to be driven into the steel sheet from the outside.
  • the height of these edges 14 is approximately 5 mm and the smallest clear diameter b 1 of the openings 13 is approximately 8 mm.
  • the openings 13 with the inwardly projecting edges 14 can also be referred to as thrust anchors.
  • the finished composite panel 10 has a square floor plan and is supported with its corners on footrests, which in turn are placed on the respective floor of the building (not shown).
  • the composite panel 10A according to the invention shown in FIG. 2 has the same two main components as the composite panel 10 of FIG. 1, namely the trough-shaped outer reinforcement 11 made of, for example, sheet steel and the mineral filler 12, for example anhydrite.
  • the filler 12 is also poured into the trough-shaped reinforcement 11 in liquid form and is then allowed to harden therein.
  • openings 13 punctures
  • frayed edges 14 projecting inwards.
  • the liquid mineral filler 12 runs out through these openings 13 here through to the outside Prevents the trough-shaped reinforcement 11 from applying liquid, hardening surface protection or finishing agent which, after hardening, forms a skin 19 on the entire outside of the trough-shaped reinforcement (bottom and side walls), which closes the openings 13 to the outside.
  • a surface protection or finishing agent for example, a quick-drying, correspondingly viscous synthetic resin varnish can be used, which is applied to the outside of the trough-shaped reinforcement 11 is sprayed on.
  • This synthetic resin varnish can contain fiber pieces, for example glass fiber pieces, as filler in order to securely close the openings 13 and to seal them outwards, as shown in FIG. 4.
  • liquid mineral filler 12 is introduced into the trough-shaped reinforcement 11 only after the surface protection and / or finishing agent has hardened or the protective and sealing skin 19 has been formed.
  • the setting time of the lacquer which consists of a quick-drying quality, can be accelerated by adding heat.
