- 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.

Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines aufgeständerten Fußbodens, bei dem einzelne vorgefertigte Ständerelemente aufgestellt werden und hiernach auf die Ständerelemente der Fußboden aufgebracht wird.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.
Das vorerwähnte Verfahren ist z.B. aus der DE-OS 26 11 372 bekannt. Dabei werden die Ständerlemente, die als den Fußboden (Oberboden) tragende Stützen ausgebildet sein können, lose auf der Rohdecke aufgestellt. Dies bringt insbesondere bei größeren Bauhöhen des Bodens den Nachteil mit sich, daß die Stützen im Zuge der Baumaßnahmen umfallen können und dann wieder aufgerichtet werden müssen. Dieser Nachteil ließe sich zwar grundsätzlich dadurch ausräumen, daß die Stützen so ausgebildet werden, daß sie eine beträchtliche Standfestigkeit besitzen. Dies würde sich jedoch deutlich kostenerhöhend auswirken. Ein weiterer Mangel der bekannten Arbeitsweise besteht darin, daß die Plazierung der einzelnen Tragelemente auf der Rohdecke verhältnismäßig zeitaufwendig ist, da hierbei auf das Rastermaß von auf die Tragelemente aufgelegten Platten Rücksicht genommen werden muß. Wenn die Platten nicht mit ihren Rändern auf den Tragelementen aufliegen, besteht die Gefahr, daß sie bei der Begehung abkippen.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.
Um den mit der Aufstellung einzelner Tragelemente für den Oberboden verbundenen Aufwand zu reduzieren, hat man mehrere Tragelemente zu einer Baueinheit zusammengefaßt (GM 88 08 154, GM 87 09 404). Dabei ist eine gewisse Anzahl von Tragstützen mit einer mehr oder weniger formsteifen Platte verbunden. Abgesehen von den durch die Sperrigkeit solcher Bauelemente bedingten Nachteilen ergibt sich die Notwendigkeit, die aufgrund des Rastermaßes der Baueinheiten im Randbereich einer Rohdecke, also unmittelbar neben den Raumwänden verbleibenden Lücken in irgendeiner Weise, beispielsweise durch Bearbeitung der Bauteile an der Baustelle, auszufüllen.In order to reduce the effort associated with the installation of individual support elements for the top floor, several support elements have been combined to form one structural unit (GM 88 08 154, GM 87 09 404). A certain number of supports are connected to a more or less rigid plate. Apart from the disadvantages caused by the bulkiness of such components, there is a need to fill in the gaps remaining due to the modular dimension of the structural units in the edge region of a bare ceiling, i.e. immediately next to the room walls, in some way, for example by processing the components at the construction site.
Die sich bei dem vorerwähnten Verfahren ergebenden Nachteile treten dann nicht auf, wenn, wie beispielsweise in der DE-OS 31 03 632 beschrieben, auf der Unterlage (Rohdecke) eine sich den Niveauabweichungen und Unebenheiten anpassende Schalung angeordnet wird, die den Tragelementen entsprechende Einbuchtungen aufweist, in welche an der Baustelle eine Estrichmasse eingebracht bzw. eingegossen wird, welche nach dem Aushärten die Tragstützen für den Oberboden bildet. Dieser kann gleichzeitig mit den Tragstützen hergestellt werden, indem die Estrichmasse über den Rand der Einbuchtungen hinaus noch in einer der gewünschten Stärke des Oberbodens entsprechenden Dicke auf die Schalung aufgebracht wird. Da die Schalung aus einzelnen Bahnen zusammengesetzt ist, die aus einer Kunststoffolie bestehen, lassen sich die Bahnen im Randbereich der Rohdecke vergleichsweise leicht auf das für die Ausfüllung etwaiger Lücken erforderliche Maß zuschneiden.The disadvantages resulting from the above-mentioned method do not occur if, as described for example in DE-OS 31 03 632, a formwork which adapts to the level deviations and unevenness is arranged on the base (raw ceiling) and has corresponding indentations for the supporting elements , into which a screed mass is poured or poured at the construction site, which forms the support for the top floor after curing. This can be produced at the same time as the support columns by applying the screed mass to the formwork over the edge of the indentations in a thickness corresponding to the desired thickness of the top floor. Since the formwork is composed of individual sheets, which consist of a plastic film, the sheets in the edge area of the raw slab can be cut comparatively easily to the size required to fill any gaps.
Wegen des Feuchtigkeitsgehalts der Estrichmasse (z.B. auf der Basis von Anhydritbinder) und der von der Verdunstung eines Anteils der Feuchtigkeit abhängigen Aushärtungszeit der Dieselben Nachteile ergeben sich grundsätzlich auch bei der Herstellung des aus der WO-A-86/06 432 bekannten Bodens. Bei diesem sind an einer auf der Rohdecke angeordneten Folie nach oben gerichtete Ausformungen vorgesehen, welche die Ständerelemente im Bereich ihres unteren Randes umschließen und somit zu deren Lokalisierung auf der Rohdecke dienen. Da sich diese Ausformungen jedoch nur über eine vergleichsweise geringe Höhe der Ständerelemente erstrecken, sind sie nicht geeignet, die Ständerelemente ausreichend gegen ein Umfallen zu sichern, vor allem dann nicht, wenn deren vertikale Erstreckung ( Höhe ) im Vergleich zur horizontalen Erstreckung ihrer Basisfläche besonders groß ist. Dabei ist zu beachten, daß für die Ständerelemente eine möglichst kleine Basisfläche angestrebt wird, damit für die Unterbringung der Installationen ein möglichst großer Freiraum verbleibt und sich dem nachträglichen Einbringen der Installationen in diesen Freiraum keine zu großen Hindernisse entgegenstellen.Because of the moisture content of the screed mass (eg based on anhydrite binder) and the curing time of the, depending on the evaporation of a part of the moisture The same disadvantages basically arise in the manufacture of the floor known from WO-A-86/06 432. In this case, upward-directed formations are provided on a film arranged on the bare ceiling, which surround the stand elements in the region of their lower edge and thus serve to locate them on the bare ceiling. However, since these formations only extend over a comparatively small height of the stand elements, they are not suitable for securing the stand elements sufficiently against falling over, especially not if their vertical extension (height) is particularly large compared to the horizontal extension of their base surface is. It should be noted that the base elements should be as small as possible so that there is as much free space as possible for the installation of the installations and that there are no obstacles to the subsequent installation of the installations in this free space.
Bei der in der WO-A-86/06 432 beschriebenen Bodenkonstruktion ist der Oberboden aus einzelnen, von den Ständerelementen abgestützten Platten zusammengesetzt. In vielen Fällen wird jedoch ein durchgehender, im Gießverfahren herzustellender und folglich fugenloser Oberboden verlangt. Die genannte Druckschrift enthält keine Hinweise wie in einem solchen Falle bei der Herstellung des Bodens verfahren, insbesondere wie die Schalung für den Oberboden ausgebildet werden soll.In the floor construction described in WO-A-86/06 432, 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.
Estrichmasse kann der Oberboden erst nach einer vergleichsweise langen Zeit (10 - 14 Tage) stärker belastet werden. Dies bringt eine Verzögerung im Fortgang der Baumaßnahmen mit sich, die in vielen Fällen unerwünscht oder sogar nicht hinnehmbar ist. Dies gilt vor allem für Bausanierungsmaßnahmen.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.
Die Aufgabe der Erfindung besteht demnach darin, ein Verfahren gemäß dem Oberbegriff des Anspruches 1 vorzuschlagen, bei dem die einzelnen vorgefertigten, kostengünstig herstellbaren Ständerelemente für den Oberboden auf einfache Weise und umfallsicher aufgestellt werden können und das sich auch für die Herstellung eines Fußbodens mit fugenlos ausgebildetem Oberboden eignet.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.
Die Lösung der Erfindungsaufgabe besteht darin, daß vor dem Aufstellen der Ständerelemente auf dem Unterboden eine sich dessen Niveauabweichungen und Unebenheiten anpassende Schalung aufgebaut wird, die aus einzelnen Bahnen zusammengesetzt ist, und eine Vielzahl von der Form und Höhe der Ständerelemente entsprechende, die Schalung gegen den Unterboden abstützende Einbuchtungen aufweist, und daß anschließend die Ständerelemente in die Einbuchtungen eingesetzt werden, von denen sie seitlich abgestützt werden.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.
Die Schalungselemente, die als Arbeitshilfe für die Plazierung der Tragstützen auf der Rohdecke fungieren, können entsprechend der vorerwähnten DE-OS 31 03 632 ausgebildet sein, also aus einer Kunststoffolienbahn, z.B. aus Polyethylen bestehen, in welche die Einbuchtungen zur Aufnahme der Ständerelemente durch Tiefziehen eingeformt sind. Die Einbuchtungen hängen über verbiegbare horizontal verlaufende Folienabschnitte zusammen. Ein derartiges Schalungselement ist vergleichsweise kostengünstig herstellbar. Die Einbuchtungen sind zweckmäßig so ausgebildet, daß sie die einzelnen vorgefertigten Ständerelemente formschlüssig umfassen. Eine Kegelstumpfform der Ständerelemente und dementsprechend auch der Einbuchtungen bzw. des von diesen umfaßten Hohlraums erweist sich als zweckmäßig. Da die Einbuchtungen der Schalungselemente eine gewisse Eigensteifigkeit besitzen und die Ständerelemente über ihre gesamte Höhe seitlich abstützen können, haben die in die Einbuchtungen eingesetzten Ständerelemente einen festen Stand. Ein Umfallen ist also ausgeschlossen.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.
Die erfindungsgemäß verwendeten Tragelemente können fabrikmäßig vorgefertigt werden in Formen, die den die Tragelemente später aufnehmenden Schalungselementen entsprechen. Vorzugsweise werden die einzelnen Tragelemente aus einer Estrichmasse, z.B. auf Anhydritbinderbasis, im Gieß- oder Stampfverfahren hergestellt. Da bei Anwendung der Erfindung an der Baustelle nicht mehr gewartet zu werden braucht, bis die die Ständerelemente bildende Estrichmasse ausgetrocknet und ausgehärtet ist, ergibt sich eine wesentliche Zeitersparnis für die Fertigstellung des Fußbodens selbst dann, wenn auf den in den Einbuchtungen der Schalungselemente sitzenden Ständerelementen an der Baustelle erst noch in an sich bekannter Weise ein Oberboden aus Estrichmasse hergestellt wird. Der zur Raumseite hin offen liegende Oberboden kann natürlich sehr viel schneller abtrocknen (in 2 bis 4 Tagen) als eine in die darunter liegenden Einbuchtungen eingebrachte Estrichmasse. Falls der Oberboden aus einer fließfähigen Estrichmasse hergestellt wird, können Niveauabweichungen der Ständerelemente, die sich als Folge der Niveauabweichungen der Unterlage ergeben, leicht ausgeglichen werden, weil sich die fließfähige Masse praktisch von selbst einnivelliert.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.
Bei der zuletzt beschriebenen Ausführungsform dient die Schalung zur Aufnahme der vorgefertigten Ständerelemente gleichzeitig auch als (verlorene) Schalung für den Oberboden.In the last-described embodiment, the formwork for receiving the prefabricated stand elements also serves as (lost) formwork for the top floor.
Um eine gute Verbindung der den Oberboden bildenden Estrichmasse mit den vorgefertigten Ständerelementen zu gewährleisten, erweist es sich als zweckmäßig, daß bereits bei der Herstellung der Ständerelemente auf deren Oberseite Vorsprünge ausgebildet werden, die sich bei der Anformung des Estrichbelags mit diesem verzahnen. Die Vorsprünge können in der Weise erzeugt werden, daß in der Oberseite der Ständerelemente vergleichsweise harte Feststoffpartikel verankert werden, beispielsweise durch teilweises Eindrücken solcher Teilchen in die noch nicht ausgehärtete Estrichmasse. Die Feststoffpartikel können beispielsweise aus grob zerkleinerter Estrichmasse oder natürlich vorkommenden Mineralkörnern wie Quarz, Kies und dergleichen oder aus Drahtstücken bestehen.In order to ensure a good connection of the screed mass forming the top floor with the prefabricated stand elements, it has proven to be expedient that 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.
Es besteht natürlich auch die Möglichkeit, entsprechend dem in der DE-OS 26 11 372 beschriebenen Verfahren auf die Tragstützen eine als verlorene Schalung wirkende, aus Gipskarton- oder Gipsfaserplatten verhältnismäßig geringer Stärke bestehende Plattenabdeckung aufzubauen und dann hiernach wieder eine den Oberboden bildende Estrichmasse aufzubringen.There is of course also the possibility, in accordance with the method described in DE-OS 26 11 372, to build up a formwork that acts as lost formwork and consists of gypsum plasterboard or gypsum fibreboard panels of relatively low thickness and then apply a screed that forms the top floor.
In Fällen, in denen eine sofortige Begehbarkeit des Oberbodens verlangt wird, also nicht einmal die Aushärtungszeit für den Oberboden akzeptabel ist, kann der Oberboden aus auf die Tragstützen aufgelegten Platten gebildet werden, welche den Festigkeitserfordernissen des Fußbodens entsprechen. Auf diese Platten, zwischen denen eine Nut/Feder-Verbindung vorhanden sein kann, kann dann anschließend unmittelbar der Nutzbelag aufgezogen werden. Etwaige Niveauunterschiede der Tragstützen können durch auf- oder untergelegte Scheiben ausgeglichen werden.In cases where an immediate accessibility of the top floor is required, i.e. not even the curing time for the top floor is acceptable, 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.

Das Ausführungsbeispiel gemäß Fig. 2 eignet sich insbesondere für solche Fälle, in denen aus Zeitgründen eine Trockenbauweise für den Fußboden verlangt wird.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.
Um etwaige Niveauunterschiede bzw. Unebenheiten auszugleichen, die durch Höhentoleranzen der Ständerelemente und/oder durch Unregelmäßigkeiten der Oberfläche der Rohdecke bedingt sind, kann auf der Oberseite der Ständerelemente und/oder auf die Rohdecke eine Lage aus einem federelastischen Werkstoff, z.B. eine Dämmlage aufgelegt werden.In order to compensate for any level differences or unevenness that are caused by height tolerances of the stand elements and / or by irregularities in the surface of the bare ceiling, a layer made of a resilient material, e.g. an insulation layer can be put on.
