Definitions
- the invention relates to a method for installing a double floor, a raised floor and designated double bottom plates.
- a raised floor traditionally consists of plates, which are placed on height-adjustable double floor supports, which are placed on the building floor or bare floor. Between the unfinished floor and the raised floor thus results in a low space in which media lines of all kinds, such as water pipes, gas pipes and electrical cables, can be installed on the shortest path, which eliminates the need for further planning of the installations.
- the raised floor panels are laid step by step. That is, when laying the double floor sequentially raised floor supports are set and adjusted and raised floor panels then placed. After placing a double bottom plate, this is measured with a spirit level and adjusted the double bottom support. In this way, the double floor is gradually expanded, with the individual steps of laying a double bottom plate and the adjustment of a double bottom support repeat alternately. Overall, a high installation effort results.
- the double bottom plates are typically removed after the construction of the double floor, so that the corresponding artisans media lines, for example, electrical cables, inserted or can be placed on the unfinished floor. After inserting the media lines, the Raised floor panels placed on the double floor supports again, often readjustments are necessary.
- FIG. 1 One from the EP0479720A1 known double bottom support is in FIG. 1 shown.
- This double bottom support comprises a foot part 220 with a base plate 221, which is connected via a connecting device 223 with a perpendicular to the base plate 221 aligned footer tube 222 elastically.
- the footer tube 222 can thus be inclined at a certain angle against the base plate 221 to compensate for unevenness of the soil.
- a head part tube 212 of a top plate 211 provided with a head portion 210 is telescopically inserted.
- the head part 210 supported by a spring 230 is displaceable against the foot part 220 until a screw stop 240 connected to the head part tube 212 strikes the foot part tube 222.
- the screw stop 240 is held by a thread and adjustable to a desired height.
- a method for laying the raised floor panels in which an auxiliary level is leveled over a multiple grids comprehensive field of the raw soil, can be adjusted by means of the grid points positioned double bottom supports to the desired height. Even with this method still results in a considerable effort to adjust the double bottom supports.
- Known raised floor panels have a solid support plate, which is usually provided at the bottom and top with a coating or a coating and laterally with an edge protection.
- the support plate is for example a wood-based panel or a reinforced mineral plate.
- Material plates of this type have a relatively high weight and low heat insulation. Furthermore, disturbing impact sound can occur in these raised floor panels.
- the corners of the raised floor panels rest on the double floor supports and are subject to relatively high loads, which is why a high strength of the support plate is provided. In this case, parts of the support plate have a high strength, although they are not subject to any corresponding load.
- the raised floor panels thus have a relatively high material requirements and corresponding manufacturing costs.
- the present invention is therefore based on the object to provide an improved raised floor, provided for improved double bottom plates and an improved method for installing the raised floor.
- the false floor should be able to be installed quickly and accurately with little effort and regardless of unevenness of the raw floor. Furthermore, the raised floor should have good insulation properties and absorb mechanical effects and thereby suppress impact sound.
- the raised floor should also be laid on a bare floor, on the pre-installations, such as cable channels, or recesses were provided that the subsequent construction of the raised floor was observed.
- the inventive double floor should also be able to be built on a subfloor, which was not originally intended.
- the raised floor panels should be inexpensive to produce and easy to handle.
- the raised floor panels should have a reduced weight.
- the method serves to install a double floor according to the invention over a raw floor.
- the raised floor has on the subfloor patch raised floor supports, of which inventive raised floor panels are supported.
- At least two double floor supports are each connected to a double floor beam, then at least two double-bottomed beams, preferably aligned in parallel and connected to double floor supports, are connected to at least two mounting beams, so that the double floor beams and the mounting beams form a mounting structure. Then the mounting structure is performed so far against the bare floor until the raised floor beams are at a defined mounting height. Now the double bottom supports, if they are not already on Abut bare soil, brought into firm contact with this. Finally, the mounting beams are removed and raised floor panels placed on the raised floor beams.
- the raised floor panels have first and second foot members which extend parallel to each other on opposite sides, preferably over the entire width of the raised floor panel.
- the double bottom plate has an interior in which a metal support structure is arranged consisting of metal rods or metal plates, which transmits the forces acting on the double bottom plates forces on the foot elements.
- a plurality of raised floor beams which are connected to two or more false floor supports, can be precisely installed at the same time.
- the double floor supports carry the double floor beams on which the double floor slabs will later be laid.
- the positions of the double floor supports below the raised floor beams can therefore be freely selected in relatively wide areas.
- areas of the Rohêts be bridged, which are not suitable for the establishment of a false floor support.
- Prefabrications, e.g. Recesses are provided with switch boxes, which are bridged by means of double floor beams. Double floor supports, which would fall into the recesses at a regular grid, can therefore be moved to the outside.
- the position of the false floor supports can thus be selected advantageously taking into account the nature of the double floor and any pre-installations.
- the double floor beams preferably have a profile into which the head pieces of the double floor supports can be pushed, so that they can be held in a form-fitting manner and moved along the double floor beams. This way you can The distance between the false floor supports can be set particularly easily.
- double floor beams are provided with openings, in each of which a head piece of a double floor support or a part thereof can be used.
- the head pieces are provided with coupling elements, for example slots, in which a tool can be used to rotate the head pieces, which are connected via a screw with a support body.
- this is preferably lowered by means of lifting devices to a defined level.
- lifting devices Preferably, motorized and controllable lift devices are provided on which the mounting structure is suspended or on which the mounting structure is supported.
- the mounting structure is preferably supported on at least three, preferably four, lifting devices and guided vertically downward by means of these lifting devices until the mounting plane is reached, which is signaled for example by means of laser devices.
- the mounting bars are e.g. held by supports on which drive devices, e.g. Electric motors are arranged, which drive a spindle.
- drive devices e.g. Electric motors are arranged, which drive a spindle.
- Each spindle engages in a bearing block connected to the associated mounting bar, which is moved vertically upwards or downwards upon rotation of the spindle with the mounting structure.
- Such spindle drives are e.g. supplied by maxon company (see maxonmotor.com).
- the foot element of the double bottom support preferably has an elastic element, for example a spiral spring, which is compressed when hitting the unfinished floor and keeps the false floor support in vertical alignment. When adjusting this support head, the elastic element is further compressed until a stable connection results or the support foot hits the subfloor.
- any adjustable double floor supports can be used.
- adjustable double floor supports can be dispensed with in a further preferred embodiment of the invention.
- base of consolidating and connecting to the subfloor base material provided on the subfloor In each of the not yet cured base is immersed in lowering the mounting structure, a double bottom support. After the assembly structure has reached the mounting height and the double floor beams are aligned at an ideal height, the double floor supports protrude more or less deeply into the base, depending on the progression of the bare floor. The mounting structure is now held until the pedestals have solidified and the double floor supports are kept stable.
- the double floor supports can be used.
- simple hollow cylindrical or rectangular tubes can be used.
- the double floor supports can also be provided with an anchor at the bottom.
- sheet metal pieces can be cut out of the pipe and bent outwards.
- the base material provided for forming the pedestals is, for example, a concrete mix, a screed concrete, a cement mix or a mortar, which is so assembled and applied that it solidifies only after a period of time within which the false floor supports are inserted. After lowering the false floor supports, the solidification of the base material can be started by supplying heat, air and / or water.
- the materials mentioned have the advantage that they quickly combine with the raw soil and solidify.
- the pedestals can be realized in different ways.
- base material is deposited at mounting positions on the subfloor.
- the base material may be provided on the underside of the double bottom supports in a container.
- the base material can also be provided within the double bottom support or can be fed through it to the raw soil.
- the raised floor panels are placed. So that raised floor panels can not move on the raised floor beams, they are preferably provided with retaining elements, such as recesses or flanges, which rest laterally on the double floor beams after installation.
- the installed double floor slabs therefore additionally stabilize the raised floor beams.
- the mounting bars are only now, after the raised floor panels were placed on the raised floor beams, pulled out and can with the installation devices continue to be used.
- the raised floor beams on the other hand, form »lost « parts of the assembly structure.
- conventional raised floor panels have a solid and heavy support plate, for example a wood-based panel or a reinforced mineral panel, which is why these raised floor panels are unfavorable in terms of handling, insulation properties and noise.
- the raised floor panels can be supported on two sides and not only at the corners. According to the invention, this circumstance is used to form double bottom plates as stable bridge constructions in which support structures are used which have a high load capacity in relation to a low dead weight.
- support structures reinforcements or trusses are preferably used, which are embedded in preferred embodiments in a lightweight and well insulating foam, which further increases the stability of the reinforcement or the truss.
- the truss preferably comprises integrally interconnected sheet metal elements or metal rods, which are loaded substantially to train or pressure and connected to a cover plate and a base plate.
- trusses for example, rectangular constructions or triangular constructions are suitable.
- the raised floor panels are preferably provided with a stable frame made of metal or plastic, which fixes the cover plate and the base plate against each other and record acting on the raised floor plate shear forces and relieve the framework accordingly.
- the invention also utilizes the fact that occurring after the installation of the raised floor panels shear forces are absorbed by adjacent raised floor panels.
- connection of the nodes of the framework with the cover plate or the base plate by adhesive or by flange or rod elements, which are used for example in openings of the cover plate and the base plate. This results in a simple assembly of the prefabricated elements.
- each Raised floor plate therefore has on opposite sides depending on an elongated, for example, bar-shaped foot element, between which the raised floor plate continuously tapers to the middle.
- double bottom plates result, which have a high strength despite the further reduced material costs.
- this can also be provided with the appropriate curvature.
- the double bottom plate is preferably foamed with rigid foam, for example rigid polyurethane foam, which forms the body of the raised floor plate after curing together with the support structure.
- rigid foam for example rigid polyurethane foam
- this body With the integrated framework or reinforcement, this body has a low weight and yet a very high load capacity. In addition, excellent insulation properties result.
- the rigid foam can be introduced in various ways in the interior of the raised floor panel. It is not necessary that the raised floor panel has a self-contained housing. A frame is preferably provided for the cover plate, after which remaining parts of the necessary shuttering are temporarily applied to the raised floor plate only for the process of foaming in order to limit the interior space. It is also particularly advantageous to use films which hold the introduced foam in position. After curing of the foam, the superfluous casing can be removed, so that a part of the rigid foam is exposed.
- the raised floor panels at the bottom preferably have at least one cable channel into which the cables can be inserted.
- the cables are therefore no longer on the bare floor and are therefore resistant to moisture and Wet protected.
- the cables are easily accessible on raised floor panels where cable ducts are provided. Cable ducts, which are preferably integrated in a truss or in a reinforcement, preferably have a cover which is received flush in the cover plate.
- a distance which allows the cable to be guided from one to the other side of the false floor beams is preferably kept to individual raised floor beams arranged serially one behind the other.
- FIG. 1 shows the known double floor 1000 described above, the adjustable double floor supports 2, the double bottom plates 100 wear.
- FIG. 1a shows the Double floor support 200 from FIG. 1 supporting the corners of four double bottom 100 double bottom plates 1.
- FIG. 2 shows the raised floor 1000 of FIG. 1 with several raised floor panels 100, which are supported at their corners by double floor supports 2.
- FIG. 3 shows two parallel aligned double floor beams 20, which are each connected to two double floor supports 2.
- the raised floor beams 20 have, for example, a hat profile, a C profile (see the double floor beam 20C) or a U profile (see the double floor beam 20U) which can receive the head 21 of the double floor supports 2.
- the head 21 of the double bottom support 2 is held positively but displaceably.
- the head 21 of the double bottom support 2 can be fixed, for example by means of a support rod 29, if desired.
- the hat profile has outwardly directed flanges, which can serve as additional support surfaces.
- the two parallel-aligned double floor beams 20 are interconnected by two mounting bars 200, whereby a mounting structure 2000 is formed.
- the mounting structure 2000 is held by one or more auxiliary devices, preferably motorized lift devices or lifting devices 5 and can be performed against the unfinished floor 3 until the raised floor beams 20 are at a mounting height h M in a mounting plane E M.
- the mounting plane E M parallel to which the raised floor 10 is to be constructed, is defined for example by means of a laser device 91.
- double bottom supports 2 are adjustable (see FIG. 7 ), so they can be adjusted after lowering the mounting structure 2000, so that they come into firm contact with the green floor 3.
- non-adjustable double bottom supports 2 are provided, which are sunk into a base material 23 after lowering the mounting structure 2000, which forms a firm connection between the unfinished bottom 3 and the held double bottom support 2 after hardening. Unevenness of the green floor 3 are compensated by differently deep immersion of the double floor supports 2 in the base material 23. Work to adjust the double floor supports 2 therefore completely eliminated.
- the raised floor panels 1 are placed on the raised floor beams 20. Previously or subsequently, the mounting bars 200 are removed. A part of the mounting structure 2000 is therefore "lost" and now forms part of the raised floor structure.
- the mounting beams 200 can be connected in any way with the raised floor beams.
- the mounting bars 200 are passed under the raised floor beams 20, so that the mounting structure 2000 can be raised or lowered by the mounting bars 200, as shown in FIG FIG. 3 is shown.
- the auxiliary devices 5 attack from above or from below to the mounting bar 200 to raise or lower this.
- the raised floor beams 20 can be provided with openings 201 into which the mounting bars 200 can be inserted. After installing the raised floor beams 20 and preferably the raised floor panels 1, the mounting beams 200 can therefore be easily pulled out of the openings 201 in the false floor beams 20.
- the raised floor panels 1 are provided with flange elements or recesses 19, which bear laterally against the raised floor beams 20 and additionally stabilize them.
- FIG. 4 shows a raised floor 10 after removal of the mounting bars 200 with raised floor panels 1, which on one of the raised floor beams 20 of FIG. 3 are supported.
- the double floor beam 20 is held by two double floor supports 2, the lower end pieces are at the same height, but are spaced differently from the green floor 3. These different distances are compensated by the hardened base 23.
- After lowering the raised floor beams 20 to the mounting height h M thus eliminates any additional adjustment, which is why according to simply configured double floor supports 2, for example, round or rectangular tubes can be used.
- FIG. 5 shows an inventive double floor 10 with two series of raised floor beams 20, which are aligned parallel to each other and according to the invention carry double floor panels 1.
- the successively arranged double floor beams 20 are arranged at intervals to one another, which allow cables 8 to pass therebetween. Cable 8 can therefore be conveniently laid from above and passed from one to the other side of the raised floor beams 20.
- FIG. 6 shows a novel raised floor 10 with raised floor panels 1 and P1, ..., P21, which are supported by five raised floor beams 20A, ..., 20E.
- the raised floor panels P10, P11, P16 and P17, which are arranged on a recess 30 in the green floor 3, are shown transparent.
- the raised floor panel P12 has been removed.
- the double bottom supports 2 are arranged at different distances from each other, so that, areas of the green floor 3, such as the recess 30, can be bridged. Therefore, other installation work can already be carried out on the unfinished floor 3 before the installation of the double floor 10.
- an electrical control box can be used, to which extend the cable 8 of the building.
- cable ducts can be pre-installed, in which cables 8 bundled out into the room.
- the inventive double floor supports 2 can now be moved and next to the Installation devices are positioned. It is also possible to move raised floor panels 1, which have different geometric shapes, but are always reliably supported on the raised floor beams 20.
- FIG. 7 shows a double bottom support 2, which has a support foot 23 and a support body 22 in which a screw 24 is rotatably supported, the screw head simultaneously forms the head 21 of the false bottom support 2.
- the column head 21 has a cylindrical extension 210, which is inserted into an opening 202 in the double floor beam 20.
- the double floor support 2 thus remains stable with the raised floor panel 20.
- a coupling element is provided, which can be coupled with a tool to grip the column head 21 and rotate. Adjustments, in particular any necessary readjustments, can therefore be carried out conveniently from above.
- FIG. 8a shows in a sectional view the production of an inventive double bottom plate 1 in a first embodiment.
- the double bottom plate 1 has a cover plate 11, a preferably self-contained frame 13 and a fragment of a base plate 12, which forms on opposite sides of the double bottom plate 1 depending on a foot element 18A and 18B.
- a support structure 16 is provided, which is concave and extends bridge-shaped from the first foot member 18A to the second foot member 18B.
- the support structure 16 consists of curved longitudinal webs 162 and straight transverse webs 161 made of metal.
- the unfinished from the base plate space is covered during the filling of a foam filling 17 by a shuttering element 70 made of plastic, which can then be removed again.
- a plastic shell or a plastic film is provided.
- a foam container 7 is shown, from the rigid foam 17 in the interior 14 of the double bottom plate. 1 is filled.
- the support structure 16 forms therein a stable reinforcement.
- the support structure 16 with the hardened rigid foam 17 therefore forms a light but at the same time very stable base body of the raised floor plate 1, which at the same time has excellent insulation properties.
- the rigid foam 17 has an elasticity, are absorbed by the mechanical effects practically without noise. Due to the concave configuration of the base side of the raised floor plate 1 also a reduction in material and thus a weight reduction is achieved. At the same time, the manufacturing costs are reduced.
- Flange elements 19 are integrally formed on the foot elements 18A, 18B and, after installation of the raised floor panels 1, bear laterally against the false floor beams 20 and are therefore securely held.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Installation eines Doppelbodens, einen Doppelboden sowie dafür vorgesehenen Doppelbodenplatten.The invention relates to a method for installing a double floor, a raised floor and designated double bottom plates.
In modernen Grossbauten werden oft Doppelböden installiert. Wie dies in der
Üblicherweise werden die Doppelbodenplatten schrittweise verlegt. D.h., beim Verlegen des Doppelbodens werden sequenziell Doppelbodenstützen gesetzt und justiert und Doppelbodenplatten sodann aufgelegt. Nach dem Auflegen einer Doppelbodenplatte wird diese mit einer Wasserwaage vermessen und die Doppelbodenstütze justiert. Auf diese Weise wird der Doppelboden schrittweise ausgebaut, wobei sich die einzelnen Schritte des Auflegens einer Doppelbodenplatte und des Justierens einer Doppelbodenstütze alternierend wiederholen. Insgesamt resultiert ein hoher Installationsaufwand. Zu beachten ist ferner, dass die Doppelbodenplatten nach dem Aufbau des Doppelbodens typischerweise wieder entfernt werden, damit von den entsprechenden Handwerkern Medienleitungen, zum Beispiel elektrische Leitungen, eingelegt bzw. auf den Rohboden aufgelegt werden können. Nach dem Einlegen der Medienleitungen werden die Doppelbodenplatten wieder auf die Doppelbodenstützen aufgelegt, wobei öfters Nachjustierungen notwendig werden.Usually, the raised floor panels are laid step by step. That is, when laying the double floor sequentially raised floor supports are set and adjusted and raised floor panels then placed. After placing a double bottom plate, this is measured with a spirit level and adjusted the double bottom support. In this way, the double floor is gradually expanded, with the individual steps of laying a double bottom plate and the adjustment of a double bottom support repeat alternately. Overall, a high installation effort results. It should also be noted that the double bottom plates are typically removed after the construction of the double floor, so that the corresponding artisans media lines, for example, electrical cables, inserted or can be placed on the unfinished floor. After inserting the media lines, the Raised floor panels placed on the double floor supports again, often readjustments are necessary.
Eine aus der
Aus den genannten Dokumenten geht hervor, dass die bekannten Doppelbodenstützen aufwändig gestaltet sind, um Unebenheiten des Rohbodens hinsichtlich Höhe und Neigung ausgleichen zu können.From the cited documents it is apparent that the known double floor supports are elaborately designed in order to be able to compensate for unevenness of the raw floor in terms of height and inclination.
Bei bekannten Verfahren zum Aufbau eines Doppelbodens ist ferner zu beachten, dass die Installateure körperlich stark beansprucht werden. Der Installateur verbringt einen hohen Anteil seiner Arbeitszeit auf dem normalerweise kalten Rohboden, wodurch die Gelenke beansprucht werden. Mit dem Aufbau der Doppelbodenstruktur von unten von oben, d.h. beginnend mit dem Setzen der Doppelbodenstützen, ist daher eine erhebliche Belastung der Installateure verbunden. Zudem ist viel Geschick und Zeitaufwand erforderlich.In known methods for building a double floor is also to be noted that the installers are physically stressed. The installer spends a large part of his working time on the normally cold unfinished soil, which stresses the joints. With the structure of the raised floor structure from below from above, ie starting with the Setting the double floor supports, therefore, a significant burden on the installers is connected. In addition, a lot of skill and time is required.
Bei bekannten Doppelbodenkonstruktionen ist ferner erforderlich, dass der Doppelboden eine regelmässige Beschaffenheit aufweist. Es ist darauf zu achten, dass keine Vertiefungen oder Installationen vorgesehen werden, welche die Positionierung der Doppelbodenstützen behindern würden.In known double floor constructions is also required that the raised floor has a regular nature. Care must be taken to ensure that no recesses or installations are provided which would hinder the positioning of the false floor supports.
Bekannte Doppelbodenplatten weisen eine massive Trägerplatte auf, die üblicherweise unten und oben mit einem Belag oder einer Beschichtung und seitlich mit einem Kantenschutz versehen ist. Die Trägerplatte ist beispielsweise eine Holzwerkstoffplatte oder eine verstärkte Mineralstoffplatte.Known raised floor panels have a solid support plate, which is usually provided at the bottom and top with a coating or a coating and laterally with an edge protection. The support plate is for example a wood-based panel or a reinforced mineral plate.
Werkstoffplatten dieser Art weisen ein relativ hohes Gewicht und eine geringe Wärmeisolation auf. Ferner kann bei diesen Doppelbodenplatten auch störender Trittschall auftreten. Die Ecken der Doppelbodenplatten liegen auf den Doppelbodenstützen auf und unterliegen relativ hohen Belastungen, weshalb eine hohe Festigkeit der Trägerplatte vorzusehen ist. Dabei weisen auch Teile der Trägerplatte eine hohe Festigkeit auf, obwohl diese keiner entsprechenden Belastung unterliegen. Die Doppelbodenplatten weisen somit einen relativ hohen Materialbedarf und entsprechende Herstellungskosten auf.Material plates of this type have a relatively high weight and low heat insulation. Furthermore, disturbing impact sound can occur in these raised floor panels. The corners of the raised floor panels rest on the double floor supports and are subject to relatively high loads, which is why a high strength of the support plate is provided. In this case, parts of the support plate have a high strength, although they are not subject to any corresponding load. The raised floor panels thus have a relatively high material requirements and corresponding manufacturing costs.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen verbesserten Doppelboden, dafür vorgesehene verbesserte Doppelbodenplatten sowie ein verbessertes Verfahren zur Installation des Doppelbodens anzugeben.The present invention is therefore based on the object to provide an improved raised floor, provided for improved double bottom plates and an improved method for installing the raised floor.
Der Doppelboden soll mit geringem Aufwand und unabhängig von Unebenheiten des Rohbodens rasch und präzise installiert werden können. Ferner soll der Doppelboden gute Isolationseigenschaften aufweisen und mechanische Einwirkungen absorbieren und dadurch Trittschall unterdrücken.The false floor should be able to be installed quickly and accurately with little effort and regardless of unevenness of the raw floor. Furthermore, the raised floor should have good insulation properties and absorb mechanical effects and thereby suppress impact sound.
Der Doppelboden soll auch auf einem Rohboden verlegt werden können, auf dem bereits Vorinstallationen, wie Kabelkanäle, oder Ausnehmungen vorgesehen wurden, dass der spätere Aufbau des Doppelbodens beachtet wurde. Der erfindungsgemässe Doppelboden soll auch auf einem Rohboden aufgebaut werden können, der ursprünglich nicht dafür vorgesehen war.The raised floor should also be laid on a bare floor, on the pre-installations, such as cable channels, or recesses were provided that the subsequent construction of the raised floor was observed. The inventive double floor should also be able to be built on a subfloor, which was not originally intended.
Für den erfindungsgemässen Doppelboden sollen einfach gestaltete Doppelbodenstützen einsetzbar sein. Auf eine Justierung der Doppelbodenstützen soll verzichtet werden können.For the novel raised floor simple designed double floor supports should be used. On an adjustment of the double floor supports should be able to do without.
Die Doppelbodenplatten sollen kostengünstig herstellbar und leicht handhabbar sein. Insbesondere sollen die Doppelbodenplatten ein reduziertes Gewicht aufweisen.The raised floor panels should be inexpensive to produce and easy to handle. In particular, the raised floor panels should have a reduced weight.
Diese Aufgabe wird mit einem Verfahren, einem Doppelboden und Doppelbodenplatten gelöst, welche die in den Ansprüchen 1, 5 und 11 angegebenen Merkmale aufweisen. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.This object is achieved with a method, a raised floor and raised floor panels having the features specified in
Das Verfahren dient der Installation eines erfindungsgemässen Doppelbodens über einem Rohboden. Der Doppelboden weist auf dem Rohboden aufgesetzte Doppelbodenstützen auf, von denen erfindungsgemässe Doppelbodenplatten getragen werden.The method serves to install a double floor according to the invention over a raw floor. The raised floor has on the subfloor patch raised floor supports, of which inventive raised floor panels are supported.
Erfindungsgemäss werden wenigstens zwei Doppelbodenstützen je mit einem Doppelbodenbalken verbunden, anschliessend werden wenigstens zwei vorzugsweise parallel ausgerichtete und mit Doppelbodenstützen verbundene Doppelbodenbalken mit wenigstens zwei Montagebalken verbunden, so dass die Doppelbodenbalken und die Montagebalken eine Montagestruktur bilden. Dann wird die Montagestruktur soweit gegen den Rohboden geführt, bis die Doppelbodenbalken auf einer definierten Montagehöhe liegen. Nun werden die Doppelbodenstützen, sofern sie nicht bereits am Rohboden anliegen, mit diesem in festen Kontakt gebracht. Abschliessend werden die Montagebalken entfernt und Doppelbodenplatten auf die Doppelbodenbalken aufgesetzt.According to the invention, at least two double floor supports are each connected to a double floor beam, then at least two double-bottomed beams, preferably aligned in parallel and connected to double floor supports, are connected to at least two mounting beams, so that the double floor beams and the mounting beams form a mounting structure. Then the mounting structure is performed so far against the bare floor until the raised floor beams are at a defined mounting height. Now the double bottom supports, if they are not already on Abut bare soil, brought into firm contact with this. Finally, the mounting beams are removed and raised floor panels placed on the raised floor beams.
Die Doppelbodenplatten weist ein erstes und ein zweites Fusselement auf, welche sich parallel zueinander auf einander gegenüberliegenden Seiten vorzugsweise über die gesamte Breite der Doppelbodenplatte erstrecken. Ferner weist die Doppelbodenplatte einen Innenraum auf, in dem eine metallene Trägerstruktur bestehend aus Metallstäben oder Metallplatten angeordnet ist, die die auf die Doppelbodenplatten einwirkenden Kräfte auf die Fusselemente überträgt.The raised floor panels have first and second foot members which extend parallel to each other on opposite sides, preferably over the entire width of the raised floor panel. Furthermore, the double bottom plate has an interior in which a metal support structure is arranged consisting of metal rods or metal plates, which transmits the forces acting on the double bottom plates forces on the foot elements.
Mit dem erfindungsgemässen Verfahren können mehrere Doppelbodenbalken, die mit zwei oder mehreren Doppelbodenstützen verbunden sind, gleichzeitig präzise installiert werden. Die Doppelbodenstützen tragen die Doppelbodenbalken, auf denen später die Doppelbodenplatten abgelegt werden. Die Positionen der Doppelbodenstützen unterhalb der Doppelbodenbalken können daher in relativ weiten Bereichen frei gewählt werden. Dadurch können Bereiche des Rohbodens überbrückt werden, die für das Aufstellen einer Doppelbodenstütze nicht geeignet sind. Auf dem Rohboden können Vorinstallationen, z.B. Ausnehmungen mit Schaltkästen, vorgesehen werden, die mittels der Doppelbodenbalken überbrückt werden. Doppelbodenstützen, die bei einem regelmässigen Raster in die Ausnehmungen fallen würden, können daher nach aussen verschoben werden. Die Position der Doppelbodenstützen kann somit vorteilhaft unter Berücksichtigung der Beschaffenheit des Doppelbodens und allfälligen Vorinstallationen gewählt werden.With the method according to the invention, a plurality of raised floor beams, which are connected to two or more false floor supports, can be precisely installed at the same time. The double floor supports carry the double floor beams on which the double floor slabs will later be laid. The positions of the double floor supports below the raised floor beams can therefore be freely selected in relatively wide areas. As a result, areas of the Rohbodens be bridged, which are not suitable for the establishment of a false floor support. Prefabrications, e.g. Recesses are provided with switch boxes, which are bridged by means of double floor beams. Double floor supports, which would fall into the recesses at a regular grid, can therefore be moved to the outside. The position of the false floor supports can thus be selected advantageously taking into account the nature of the double floor and any pre-installations.
Die Doppelbodenbalken weisen vorzugsweise ein Profil auf, in das die Kopfstücke der Doppelbodenstützen hineingeschoben werden können, so dass sie formschlüssig gehalten und entlang dem Doppelbodenbalken verschoben werden können. Auf diese Weise kann der Abstand zwischen den Doppelbodenstützen besonders einfach eingestellt werden.The double floor beams preferably have a profile into which the head pieces of the double floor supports can be pushed, so that they can be held in a form-fitting manner and moved along the double floor beams. This way you can The distance between the false floor supports can be set particularly easily.
Alternativ werden Doppelbodenbalken mit Öffnungen versehen, in die je ein Kopfstück einer Doppelbodenstütze oder ein Teil davon eingesetzt werden kann. Vorzugsweise werden die Kopfstücke mit Kopplungselementen, beispielsweise Schlitzen versehen, in die ein Werkzeug eingesetzt werden kann, um die Kopfstücke, die über eine Schraube mit einem Stützenkörper verbunden sind, zu drehen.Alternatively, double floor beams are provided with openings, in each of which a head piece of a double floor support or a part thereof can be used. Preferably, the head pieces are provided with coupling elements, for example slots, in which a tool can be used to rotate the head pieces, which are connected via a screw with a support body.
Nach dem Zusammenbau der Montagestruktur wird diese vorzugsweise mittels Liftvorrichtungen auf eine definierte Ebene abgesenkt. Vorzugsweise sind motorisierte und steuerbare Liftvorrichtungen vorgesehen, an denen die Montagestruktur aufgehängt ist oder auf die die Montagestruktur abgestützt ist.After assembly of the mounting structure, this is preferably lowered by means of lifting devices to a defined level. Preferably, motorized and controllable lift devices are provided on which the mounting structure is suspended or on which the mounting structure is supported.
Die Montagestruktur wird vorzugsweise auf wenigstens drei, vorzugsweise vier, Liftvorrichtungen gestützt und mittels diesen Liftvorrichtungen vertikal nach unten geführt, bis die Montageebene erreicht ist, die beispielsweise anhand von Lasergeräten signalisiert wird. Die Montagebalken werden z.B. durch Stützen gehalten, auf denen Antriebsvorrichtungen, z.B. Elektromotoren, angeordnet sind, die eine Spindel antreiben. Jede Spindel greift in einen mit dem zugehörigen Montagebalken verbundenen Lagerblock ein, der bei Drehung der Spindel mit der Montagestruktur vertikal nach oben oder nach unten gefahren wird. Derartige Spindelantriebe werden z.B. von der Firma maxon geliefert (siehe maxonmotor.com). Es sind auch beliebige weitere vorzugsweise steuerbare Liftvorrichtungen, hydraulische und pneumatische Hebevorrichtungen, einsetzbar, welche es erlauben, die Montagestruktur vertikal zu verschieben.The mounting structure is preferably supported on at least three, preferably four, lifting devices and guided vertically downward by means of these lifting devices until the mounting plane is reached, which is signaled for example by means of laser devices. The mounting bars are e.g. held by supports on which drive devices, e.g. Electric motors are arranged, which drive a spindle. Each spindle engages in a bearing block connected to the associated mounting bar, which is moved vertically upwards or downwards upon rotation of the spindle with the mounting structure. Such spindle drives are e.g. supplied by maxon company (see maxonmotor.com). There are also any other preferably controllable lifting devices, hydraulic and pneumatic lifting devices, used, which allow to move the mounting structure vertically.
Nach dem Absenken der Montagestruktur auf die vorgesehene Montagehöhe geht der Installateur von Doppelbodenstütze zu Doppelbodenstütze und nimmt mit seinem Werkzeug, beispielsweise einem Schraubendreher, die erforderliche Justierung vor. Die Höhe der einfach ausgestalteten Doppelbodenstützen kann somit mit wenigen Handgriffen an einen unebenen Rohboden angepasst werden. Das Fusselement der Doppelbodenstütze weist vorzugsweise ein elastisches Element auf, beispielsweise eine Spiralfeder, welche beim Auftreffen auf den Rohboden komprimiert wird und die Doppelbodenstütze in vertikaler Ausrichtung hält. Beim Justieren dies Stützenkopfs wird das elastische Element weiter komprimiert, bis eine stabile Verbindung resultiert oder der Stützensfuss auf dem Rohboden auftrifft.After lowering the mounting structure to the intended mounting height, the installer goes from double bottom support to double bottom support and takes with his tool, for example a screwdriver, the required adjustment before. The height of the simply designed double floor supports can thus be adapted in a few steps to an uneven floor. The foot element of the double bottom support preferably has an elastic element, for example a spiral spring, which is compressed when hitting the unfinished floor and keeps the false floor support in vertical alignment. When adjusting this support head, the elastic element is further compressed until a stable connection results or the support foot hits the subfloor.
Grundsätzlich können beliebige justierbare Doppelbodenstützen verwendet werden. Auf justierbare Doppelbodenstützen kann in einer weiteren vorzugsweisen Ausgestaltung der Erfindung verzichtet werden. Dazu werden vor, während oder nach der Positionierung der Doppelbodenstützen Sockel aus sich verfestigendem und mit dem Rohboden verbindendem Sockelmaterial auf dem Rohboden vorgesehen. In jeden der noch nicht ausgehärteten Sockel wird beim Absenken der Montagestruktur eine Doppelbodenstütze eingetaucht. Nachdem die Montagestruktur die Montagehöhe erreicht hat und die Doppelbodenbalken in idealer Höhe ausgerichtet sind, ragen die Doppelbodenstützen, in Abhängigkeit des Verlaufs des Rohbodens, mehr oder weniger tief in die Sockel hinein. Die Montagestruktur wird nun so lange gehalten, bis sich die Sockel verfestigt haben und die Doppelbodenstützen stabil gehalten sind.In principle, any adjustable double floor supports can be used. On adjustable double floor supports can be dispensed with in a further preferred embodiment of the invention. For this purpose, prior to, during or after the positioning of the false floor supports base of consolidating and connecting to the subfloor base material provided on the subfloor. In each of the not yet cured base is immersed in lowering the mounting structure, a double bottom support. After the assembly structure has reached the mounting height and the double floor beams are aligned at an ideal height, the double floor supports protrude more or less deeply into the base, depending on the progression of the bare floor. The mounting structure is now held until the pedestals have solidified and the double floor supports are kept stable.
Durch die Verwendung der sich verfestigenden Sockel werden Unebenheiten des Rohbodens ausgeglichen, weshalb die Justierung der Doppelbodenstützen entfällt. Somit können besonders einfache Doppelbodenstützen verwendet werden. Beispielsweise können einfache hohlzylindrische oder rechteckige Rohre verwendet werden. Damit eine stabile Verbindung zwischen dem Sockel und der Doppelbodenstütze resultiert, können die Doppelbodenstützen an der Unterseite auch mit einem Anker versehen werden. Dazu können Blechstücke aus dem Rohr ausgeschnitten und nach aussen gebogen werden.By using the solidifying base unevenness of the raw soil are compensated, which is why the adjustment of the false floor supports deleted. Thus, particularly simple double floor supports can be used. For example, simple hollow cylindrical or rectangular tubes can be used. For a stable connection between the base and the false floor support, the double floor supports can also be provided with an anchor at the bottom. For this purpose, sheet metal pieces can be cut out of the pipe and bent outwards.
Das zur Bildung der Sockel vorgesehene Sockelmaterial ist beispielsweise eine Betonmischung, ein Estrichbeton, eine Zementmischung oder ein Mörtel, welcher derart zusammengesetzt ist und angewendet wird, dass er sich erst nach einer Zeitspanne verfestigt, innerhalb der die Doppelbodenstützen eingesetzt werden. Nach dem Absenken der Doppelbodenstützen kann die Verfestigung des Sockelmaterials durch Zufuhr von Wärme, Luft und/oder Wasser in Gang gesetzt werden. Die genannten Materialien haben den Vorteil, dass sie sich rasch mit dem Rohboden verbinden und verfestigen.The base material provided for forming the pedestals is, for example, a concrete mix, a screed concrete, a cement mix or a mortar, which is so assembled and applied that it solidifies only after a period of time within which the false floor supports are inserted. After lowering the false floor supports, the solidification of the base material can be started by supplying heat, air and / or water. The materials mentioned have the advantage that they quickly combine with the raw soil and solidify.
Die Sockel können auf verschiedene Arten realisiert werden. Beispielsweise wird Sockelmaterial an Montagepositionen auf dem Rohboden deponiert. Alternativ kann das Sockelmaterial an der Unterseite der Doppelbodenstützen in einem Behälter vorgesehen sein. Alternativ kann das Sockelmaterial auch innerhalb der Doppelbodenstütze vorgesehen sein oder durch diese hindurch dem Rohboden zugeführt werden.The pedestals can be realized in different ways. For example, base material is deposited at mounting positions on the subfloor. Alternatively, the base material may be provided on the underside of the double bottom supports in a container. Alternatively, the base material can also be provided within the double bottom support or can be fed through it to the raw soil.
Nach der Justierung der Doppelbodenstützen oder nach dem Aushärten der Sockel werden die Doppelbodenplatten aufgesetzt. Damit sich Doppelbodenplatten auf den Doppelbodenbalken nicht verschieben können, sind sie vorzugsweise mit Halteelementen, wie Ausnehmungen oder Flanschen versehen, die nach der Installation seitlich an den Doppelbodenbalken anliegen. Die installierten Doppelbodenplatten stabilisieren die Doppelbodenbalken daher zusätzlich.After adjustment of the double floor supports or after hardening of the base, the raised floor panels are placed. So that raised floor panels can not move on the raised floor beams, they are preferably provided with retaining elements, such as recesses or flanges, which rest laterally on the double floor beams after installation. The installed double floor slabs therefore additionally stabilize the raised floor beams.
Vorzugsweise werden die Montagebalken erst jetzt, nachdem die Doppelbodenplatten auf die Doppelbodenbalken aufgesetzt wurden, herausgezogen und können mit den Installationsvorrichtungen weiter verwendet werden. Die Doppelbodenbalken bilden hingegen »verlorene« Teile der Montagestruktur.Preferably, the mounting bars are only now, after the raised floor panels were placed on the raised floor beams, pulled out and can with the installation devices continue to be used. The raised floor beams, on the other hand, form »lost« parts of the assembly structure.
Mit dem erfindungsgemässen Verfahren erfolgt neu ein Aufbau des Doppelbodens von oben nach unten. Zuerst wird die Montagestruktur mit den Montagebalken, den Doppelbodenbalken und den Doppelbodenstützen erstellt, die anschliessend von oben gegen den Rohboden abgesenkt wird. Erst jetzt erfolgt die Justierung der einstellbaren Doppelbodenstützen oder die Verbindung der Doppelbodenstützen mit dem Rohboden durch die sich verfestigenden Sockel. Der Aufbau erfolgt somit nicht in einem Aufbauprozess von unten nach oben, bei dem zuerst die Doppelbodenstützen positioniert und justiert werden müssen. Das neue Verfahren hat zahlreiche Vorteile. Das aufwändige Aufstellen und Justieren der Doppelbodenstützen wird durch das einfache Verbinden der Doppelbodenstützen mit der Montagestruktur bzw. den Doppelbodenbalken ersetzt. Das Justieren der Doppelbodenstützen entfällt entweder vollständig oder wird durch einen bequem und rasch durchzuführenden Justiervorgang ersetzt, bei dem die Doppelbodenstützen bereits gehalten sind und vorzugsweise von oben mit wenigen Handgriffen justiert werden können.With the method according to the invention, a new construction of the double bottom takes place from top to bottom. First, the assembly structure with the mounting beams, the false floor beams and the false floor supports is created, which is then lowered from above against the unfinished floor. Only now is the adjustment of the adjustable double floor supports or the connection of the double floor supports with the raw floor through the solidifying base. The structure is thus not in a building process from bottom to top, in which first the double floor supports must be positioned and adjusted. The new process has many advantages. The complex setting up and adjustment of the double floor supports is replaced by the simple connection of the double floor supports with the mounting structure or the double floor beams. The adjustment of the double floor supports deleted either completely or is replaced by a convenient and quickly performed adjustment, in which the double bottom supports are already held and can be adjusted from above with a few simple steps.
Nach der Installation der der Doppelbodenstützen mit den Doppelbodenbalken können konventionelle Doppelbodenplatten in einfacher Weise auf die Doppelbodenbalken abgelegt werden.After installing the double floor columns with the double floor beams, conventional raised floor panels can be easily placed on the raised floor beams.
Wie eingangs erwähnt, weisen konventionelle Doppelbodenplatten eine massive und schwere Trägerplatte, beispielsweise eine Holzwerkstoffplatte oder eine verstärkte Mineralstoffplatte, auf, weshalb diese Doppelbodenplatten hinsichtlich der Handhabung, der Isolationseigenschaften und der Geräuschentwicklung unvorteilhaft sind.As mentioned above, conventional raised floor panels have a solid and heavy support plate, for example a wood-based panel or a reinforced mineral panel, which is why these raised floor panels are unfavorable in terms of handling, insulation properties and noise.
Aufgrund der Verwendung der Doppelbodenbalken können die Doppelbodenplatten auf zwei Seiten und nicht nur an den Ecken abgestützt werden. Erfindungsgemäss wird dieser Umstand dazu genutzt, Doppelbodenplatten als stabile Brückenkonstruktionen auszubilden, bei denen Tragstrukturen eingesetzt werden, die im Verhältnis zu einem geringen Eigengewicht eine hohe Tragfähigkeit aufweisen. Als Tragstrukturen werden vorzugsweise Armierungen oder Fachwerke eingesetzt, welche in bevorzugter Ausgestaltungen in einem leichten und gut isolierenden Schaumstoff eingebettet werden, welcher die Stabilität der Armierung oder des Fachwerks weiter erhöht.Due to the use of false floor beams, the raised floor panels can be supported on two sides and not only at the corners. According to the invention, this circumstance is used to form double bottom plates as stable bridge constructions in which support structures are used which have a high load capacity in relation to a low dead weight. As support structures reinforcements or trusses are preferably used, which are embedded in preferred embodiments in a lightweight and well insulating foam, which further increases the stability of the reinforcement or the truss.
Das Fachwerk umfasst vorzugsweise einstückig miteinander verbundene Metallblechelemente oder Metallstäbe, welche im Wesentlichen auf Zug oder Druck belastet und mit einer Deckplatte sowie einer Grundplatte verbunden sind. Als Fachwerke sind beispielsweise Rechteck-Konstruktionen oder Dreieck-Konstruktionen geeignet. Dabei werden die Doppelbodenplatten vorzugsweise mit einem stabilen Rahmen aus Metall oder Kunststoff versehen, welcher die Deckplatte und die Grundplatte gegeneinander fixiert und auf die Doppelbodenplatte einwirkende Scherkräfte aufnehmen und das Fachwerk entsprechend entlasten kann. Die Erfindung nutzt zudem den Umstand, dass nach der Installation der Doppelbodenplatten auftretende Scherkräfte durch benachbarte Doppelbodenplatten aufgefangen werden.The truss preferably comprises integrally interconnected sheet metal elements or metal rods, which are loaded substantially to train or pressure and connected to a cover plate and a base plate. As trusses, for example, rectangular constructions or triangular constructions are suitable. The raised floor panels are preferably provided with a stable frame made of metal or plastic, which fixes the cover plate and the base plate against each other and record acting on the raised floor plate shear forces and relieve the framework accordingly. The invention also utilizes the fact that occurring after the installation of the raised floor panels shear forces are absorbed by adjacent raised floor panels.
Die Verbindung der Knotenpunkte des Fachwerks mit der Deckplatte oder der Grundplatte erfolgt durch Klebstoff oder durch Flanschelemente oder Stabelemente, die zum Beispiel in Öffnungen der Deckplatte und der Grundplatte eingesetzt werden. Dadurch resultiert ein einfacher Zusammenbau der vorgefertigten Elemente.The connection of the nodes of the framework with the cover plate or the base plate by adhesive or by flange or rod elements, which are used for example in openings of the cover plate and the base plate. This results in a simple assembly of the prefabricated elements.
Die Doppelbodenplatten können vorteilhaft mit einem Querschnitt versehen werden, dessen Grundseite konkav ist. Jede Doppelbodenplatte weist daher an gegenüberliegenden Seiten je ein langgestrecktes, beispielsweise balkenförmiges Fusselement auf, zwischen denen sich die Doppelbodenplatte bis zur Mitte hin kontinuierlich verjüngt. Auf diese Weise resultieren Doppelbodenplatten, die trotz des weiter reduzierten Materialaufwands über eine hohe Festigkeit verfügen. Bei der Verwendung eines Fachwerks kann dieses ebenfalls mit der entsprechenden Wölbung versehen werden.The raised floor panels can advantageously be provided with a cross section whose base side is concave. each Raised floor plate therefore has on opposite sides depending on an elongated, for example, bar-shaped foot element, between which the raised floor plate continuously tapers to the middle. In this way, double bottom plates result, which have a high strength despite the further reduced material costs. When using a truss, this can also be provided with the appropriate curvature.
Die Doppelbodenplatte wird vorzugsweise mit Hartschaumstoff, beispielsweise Polyurethan-Hartschaumstoff ausgeschäumt, der nach dem Aushärten zusammen mit der Trägerstruktur den Körper der Doppelbodenplatte bildet. Mit dem darin integrierten Fachwerk oder der Armierung weist dieser Körper ein geringes Gewicht und trotzdem eine sehr hohe Tragfähigkeit auf. Zudem resultieren ausgezeichnete Isolationseigenschaften.The double bottom plate is preferably foamed with rigid foam, for example rigid polyurethane foam, which forms the body of the raised floor plate after curing together with the support structure. With the integrated framework or reinforcement, this body has a low weight and yet a very high load capacity. In addition, excellent insulation properties result.
Der Hartschaumstoff kann auf verschiedene Weise in den Innenraum der Doppelbodenplatte eingeführt werden. Dabei ist es nicht notwendig, dass die Doppelbodenplatte ein in sich geschlossenes Gehäuse aufweist. Zur Deckplatte wird vorzugsweise ein Rahmen vorgesehen, wonach verbleibende Teile der notwendigen Verschalung nur für den Prozess der Ausschäumung temporär an die Doppelbodenplatte angelegt werden, um den Innenraum zu begrenzen. Besonders vorteilhaft können auch Folien verwendet werden, welche den eingeführten Schaumstoff in Position halten. Nach der Aushärtung des Schaumstoffs kann die überflüssige Verschalung entfernt werden, so dass ein Teil des Hartschaumstoffs frei liegt.The rigid foam can be introduced in various ways in the interior of the raised floor panel. It is not necessary that the raised floor panel has a self-contained housing. A frame is preferably provided for the cover plate, after which remaining parts of the necessary shuttering are temporarily applied to the raised floor plate only for the process of foaming in order to limit the interior space. It is also particularly advantageous to use films which hold the introduced foam in position. After curing of the foam, the superfluous casing can be removed, so that a part of the rigid foam is exposed.
Damit Kabel, die unterhalb des Doppelbodens verlegt werden, optimal geschützt sind, weisen die Doppelbodenplatten an der Unterseite vorzugsweise wenigstens einen Kabelkanal auf, in die die Kabel eingelegt werden können. Die Kabel liegen daher nicht mehr auf dem Rohboden und sind somit gegen Feuchtigkeit und Nässe geschützt. Zudem sind die Kabel bei Doppelbodenplatten leicht zugänglich, an denen Kabeldurchlässe vorgesehen sind. Kabeldurchlässe, die vorzugsweise in ein Fachwerk oder in eine Armierung integriert werden, weisen vorzugsweise eine Abdeckung auf, die bündig in der Deckplatte aufgenommen ist.In order for cables that are routed below the false floor to be optimally protected, the raised floor panels at the bottom preferably have at least one cable channel into which the cables can be inserted. The cables are therefore no longer on the bare floor and are therefore resistant to moisture and Wet protected. In addition, the cables are easily accessible on raised floor panels where cable ducts are provided. Cable ducts, which are preferably integrated in a truss or in a reinforcement, preferably have a cover which is received flush in the cover plate.
Damit Kabel vorteilhaft verlegt werden können, wird einzelnen seriell hintereinander angeordneten Doppelbodenbalken vorzugsweise ein Abstand eingehalten, welcher erlaubt, das Kabel von einer zur anderen Seite der Doppelbodenbalken zu führen.So that cables can be laid advantageously, a distance which allows the cable to be guided from one to the other side of the false floor beams is preferably kept to individual raised floor beams arranged serially one behind the other.
