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 supporting 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 because the supports are designed so that they have a considerable stability.
• Another shortcoming 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.
• 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.
• a formwork which adapts to its level deviations and unevenness is applied, which is composed of individual sheets, and has a large number of indentations corresponding to the shape of the upright elements and that the upright elements are then inserted into the indentations, from which they are to the side are supported.
• the formwork elements which act as a work aid for the placement of the support columns on the bare ceiling, could 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 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. Due to the inherent rigidity of the wall of the recesses of the formwork elements and this itself have the used in the recesses
• the support elements used according to the invention can be prefabricated in the factory in shapes that correspond to the formwork elements that will later receive the support elements.
• the individual supporting elements are preferably made of a screed mass, e.g. made from anhydrite binder, in a casting or pounding process. Since, when using the invention at the construction site, there is no longer any need to wait until the screed material forming the stand elements has dried out and hardened, this saves a considerable amount of time for the completion of the floor even if the stand elements 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 open to the room, 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 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 roughly 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. Exemplary examples of the method according to the invention are explained with the aid of the drawing. Show it:
• Fig. 1 shows an embodiment of the invention, in which an upper floor is produced in the casting process on the prefabricated stand elements
• Fig. 2 shows another embodiment of the invention, in which the prefabricated stand elements are constructed from prefabricated prefabricated elements.
• 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 dimension in the edge area of the raw ceiling 1 in order to fill in gaps that deviate from the grid dimension of the webs.
• Embodiment have on their top mushroom-shaped approaches 3 ', which interlock with the screed compound forming the top floor 4, preferably processable with the flow process.
• 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; rather, the top floor is composed of prefabricated panels, for example 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 of a resilient material e.g. an insulation layer can be put on.
