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 the reinforcement in a flowable state, e.g. B. anhydrite, wherein the composite effect between the hardened filler and the trough-shaped reinforcement is produced by openings (punches) provided in the bottom and side walls thereof with inwardly projecting, frayed edges, and furthermore the trough-shaped reinforcement on its outside with a leakage of the filler is coated 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 the reinforcement in a flowable state, e.g. B. anhydrite
  • 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.
  • Anhydrite-preventing layer consists of a liquid or plastically applied and then cured surface protection and / or finishing agent which, as a closed skin, closes the openings (punctures) in the trough-shaped reinforcement which are produced with a correspondingly small clear diameter in a variety similar to a grater.
  • This method of sealing the breakthroughs (punches) requires a surface protection or finishing agent with a corresponding viscosity and a clear diameter of the breakthroughs (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 is the transmitted thrust before the filling material tears off the trough bottom.
  • a very large number of small punches can therefore transmit a significantly higher thrust than a small number of large punches, while on the other hand the weakening of the soil and thus the reduction in tensile force in the soil does not increase to the same extent.
  • the second finding is that small breakthroughs (punctures) can be rationally sealed with 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. B. anhydrite is introduced. This prevents the liquid filled curable mineral filler from leaking through the openings (punctures).
  • An embodiment of the invention provides that the skin closing the breakthroughs is formed by a quick-drying lacquer that contains a filler made of z. B. contains fiber pieces.
  • the filler advantageously settles in the funnel-shaped openings and thereby favors the formation of "sealing plugs" on the skin in the openings.
  • the skin that closes the openings can be a zinc skin.
  • This zinc skin can e.g. B. by spraying a zinc dust paint or in the course of hot-dip galvanizing the trough-shaped reinforcement made of sheet steel.
  • the composite plate 10 shown in Fig. 1 of known type has a trough-shaped outer reinforcement 11 made of z. B. steel sheet and a curable mineral filler 12, z. B. 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 (punches) which have frayed edges 14 which protrude inwards. These openings 13 are produced by means of pointed mandrels to be driven into the steel sheet from the outside.
  • the height of these edges 14 is about 5 mm and the smallest clear diameter b, the openings 13 is about 8 mm.
  • the openings 13 with the inwardly projecting edges 14 can also be referred to as thrust anchors.
  • thrust anchors In order to avoid leakage of the same through these openings 13 when filling the liquid mineral filler 12 into the trough-shaped reinforcement 11, aluminum foils 17 and 18 which adhere to the openings have been glued to the outside of the bottom 15 and the side walls 16 of the trough-shaped reinforcement 13 close to the outside.
  • the finished composite panel 10 has a square plan and is supported with its corners on foot supports, which in turn are set up on the respective building floor (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 e.g. B. steel sheet and the mineral filler 12, z. B. 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 (punches) with inwardly projecting, frayed edges 14 are also used.
  • the leakage of the liquid mineral filler 12 through these openings 13 is here through to the outside prevents the tub-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 tub-shaped reinforcement (bottom and side walls) which closes the openings 13 to the outside.
  • a surface protection or finishing agent z. B. a fast drying corresponding viscous synthetic resin lacquer can be used, which is sprayed onto the outside of the trough-shaped reinforcement 11.
  • This synthetic resin varnish can fiber pieces, for. B. contain glass fiber pieces as filler to securely close the openings 13 and to seal to the outside, as shown in Fig. 4 5.
  • 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 paint which consists of a quick-drying quality, can be accelerated by adding heat.
