Definitions

  • the invention relates to a method for producing a raised floor, in which individual prefabricated stand elements are set up and the floor is subsequently applied to the stand elements.
  • the aforementioned method is known for example from DE-OS 26 11 372.
  • the stand elements which can be designed as supports that support the floor (top floor), are placed loosely on the bare ceiling.
  • This has the disadvantage, in particular in the case of greater overall heights of the floor, that the supports can fall over in the course of the construction measures and then have to be erected again.
  • This disadvantage could in principle be eliminated by designing the supports so that they have considerable stability. However, this would significantly increase costs.
  • Another defect of the known method of operation is that the placement of the individual support elements on the bare ceiling is relatively time-consuming, since the grid dimension of plates placed on the support elements must be taken into account. If the plates do not rest with their edges on the support elements, there is a risk that they will tip over during the inspection.
  • the top floor is composed of individual plates supported by the stand elements. In many cases, however, a continuous top layer that is to be produced using the casting process and is consequently seamless is required.
  • the cited document contains no information as to how to proceed in such a case in the manufacture of the floor, in particular how the formwork for the top floor should be designed.
  • Screed can only be subjected to a higher load on the topsoil after a comparatively long time (10-14 days). This entails a delay in the progress of the construction work, which is undesirable or even unacceptable in many cases. This applies above all to building renovation measures.
  • the object of the invention is therefore to propose a method according to the preamble of claim 1, in which the individual prefabricated, inexpensive to manufacture stand elements for the top floor can be set up in a simple and safe manner and also for the production of a floor with seamless design Suitable for topsoil.
  • the solution to the problem of the invention is that before the stand elements are set up on the sub-floor, a formwork which adapts to its level deviations and unevenness is built up, which is composed of individual sheets, and a multiplicity of the shape and height of the stand elements, the formwork against the Has underbody supporting indentations, and that the stand elements are then inserted into the indentations, from which they are supported laterally.
  • the formwork elements which act as a tool for placing the support columns on the bare ceiling, can be designed in accordance with the aforementioned DE-OS 31 03 632, that is to say they consist of a plastic sheet, for example made of polyethylene, into which the indentations for receiving the upright elements are molded by deep drawing are. The indentations are connected by bendable, horizontally running film sections.
  • Such a thing Formwork element is comparatively inexpensive to manufacture.
  • the indentations are expediently designed such that they encompass the individual prefabricated stand elements in a form-fitting manner. A truncated cone shape the stand elements and, accordingly, the indentations or the cavity enclosed by them have proven to be expedient. Since the indentations of the formwork elements have a certain intrinsic stiffness and can support the stand elements laterally over their entire height, the stand elements inserted into the indentations have a firm stand. Tipping over is therefore impossible.
  • the support elements used according to the invention can be prefabricated in the factory in shapes which correspond to the formwork elements which will later receive the support elements.
  • the individual supporting elements are preferably produced from a screed mass, for example based on anhydrite binder, in a pouring or ramming process. Since, when using the invention at the construction site, there is no longer any need to wait until the screed material forming the upright elements has dried out and hardened, this saves a considerable amount of time for the completion of the floor even if the upright elements are seated in the indentations of the formwork elements the construction site is still a top floor made of screed mass in a conventional manner.
  • the top floor which is exposed to the room side, can of course dry much faster (in 2 to 4 days) than a screed compound placed in the indentations below. If the top floor is made of a flowable screed mass, level deviations of the stand elements, which result as a result of the level deviations of the base, can be easily compensated for, because the flowable mass practically levels itself out.
  • the formwork for receiving the prefabricated stand elements also serves as (lost) formwork for the top floor.
  • protrusions are already formed on the upper side during the manufacture of the stand elements, which interlock with the screed covering when it is formed.
  • the projections can be produced in such a way that comparatively hard solid particles are anchored in the top of the stand elements, for example by partially pressing such particles into the not yet hardened screed mass.
  • the solid particles can consist, for example, of coarsely ground screed or naturally occurring mineral grains such as quartz, gravel and the like, or of pieces of wire.
  • the top floor can be formed from plates placed on the support supports, which meet the strength requirements of the floor.
  • the useful covering can then be applied directly to these plates, between which a tongue and groove connection can be present. Any differences in level of the support columns can be compensated for by placed or underlaid washers.
  • a formwork denoted overall by 2, which preferably consists of a plastic film, in which indentations 2 'are formed, which are connected by bendable film sections 2' '.
  • the formwork consists of several tracks having the mentioned parts 2 'and 2' ', which can be suitably, e.g. by gluing or welding to form the overall formwork 2. Since the webs in the area of the film sections 2 ′′ are easily severable, they can be cut to the required size in the edge area of the raw ceiling 1 in order to fill in gaps that deviate from the grid dimension of the webs.
  • Prefabricated, block-like stand elements 3 are inserted into the indentations 2 ', which completely fill the indentations 2' and which, in the exemplary embodiment shown in FIG Screed compound that can be processed in the flow process interlock with this.
  • the exemplary embodiment shown in FIG. 2 differs from the exemplary embodiment according to FIG. 1 in that no seamless screed is applied to the stand elements 3 or to the formwork 2 at the construction site; the top floor is rather made of prefabricated panels, e.g. composed of plasterboard or gypsum fiber material, to which a useful covering 6 is applied.
  • the embodiment according to FIG. 2 is particularly suitable for those cases in which a dry construction for the floor is required for reasons of time.
  • a layer made of a resilient material e.g. an insulation layer can be put on.
