Description

The invention relates to a double floor construction with Belagtafeln and a raised to a subfloor support structure on which the Belagtafeln are bordering abutting at a distance from the subfloor laid, the support structure includes support rails extending below the joints between the Belagtafeln along the joints, the Belagtafeln and support rails means for vertically attaching the Belagtafeln on the support rails with horizontal compression of the shock-forming edge sides of the Belagtafeln comprise, wherein the support rails have a running under the respective shock longitudinal channel, in the formed on the edge sides of the Belagtafeln hook legs can be inserted.

From the EP 1 628 733 A2 is a laying low labor floor covering known which comprises Belagtafeln having a rigid lower support layer and an upper, formed for example by tiling decorative layer. An intermediate layer is foamed or molded onto the carrier layer and the decorative layer. The interlayer is integrally formed into a skirt as well as means for marginally bonding the skin panels, with the perimeter and equipment made simultaneously with the interlayer.

From the EP 1 760 222 A2 is a double floor construction known whose support rails has an inverted T-profile. A leg of the T-profile comes between juxtaposed Belagtafeln to the arrangement.

A double floor construction of the type mentioned above with a raised support structure goes out of the US 2,956,653 A1 out. Carrier rails of the support structure have a flat receiving channel for hook legs abutting Belagtafeln, wherein the side walls of the flat receiving channel are inclined to the channel bottom. The abutting against the inclined side walls hook legs are compressed under the influence of the dead load of Bellagafeln due to the inclination of the side walls. Another double floor construction of the type mentioned is from the US 2,401,587 A known.

The invention has for its object to provide a new double floor construction of the type mentioned above, which can be produced with little effort, which has a high fluid tightness and airtightness and their Belagtafeln can be replaced quickly.

The double floor construction according to the invention which achieves this object is characterized in that the hook legs can be latched in the longitudinal channel in the compressed state of the edge sides of the covering panels.

When inserting transverse forces arising Bellagafeln pull together edge, which is advantageous stabilization and additional sealing of the lining is connected.

Advantageously, the Belagtafeln in the connection with each other and in a disassembly only to move vertically, cumbersome horizontal movements account for mutual connection. Each individual covering panel can be easily removed from the surface association as required, for example Replace with a covering panel with integrated socket. The horizontal pressing of the lining panels with each other ensures tightness of the covering.

In a further embodiment of the invention, the mounting rails have a longitudinal channel forming U-profile, which deviates in material from the rest of the mounting rail. This U-profile can e.g. be made with high accuracy of aluminum or plastic, while the rest of the support rail, for. may be formed by a steel profile subject to larger manufacturing tolerances, in particular steel U-profile.

Advantageously, the former U-profile, on the outside of a Einrastschenkel can be arranged to engage in the rest of the mounting rail, on the inner sides of the U-legs each have a projection, in particular a locking projection on which the said hook leg snaps.

In a further embodiment of the invention, means for vertically attaching the lining panels to the carrier rails are integrally formed on an intermediate layer of the lining panel which is foamed or molded between a carrier layer and a decorative layer. This intermediate layer may e.g. Made of polyurethane foam.

The U-profile forming the longitudinal channel adjusts to the edge plates under horizontal contact pressure abutting Belagtafeln and over the intermediate layer produced tongue and groove joints between the Belagtafeln and the tongue and groove joints between the Belagtafeln and the U-profile produced via the intermediate layer, so to speak, a third sealing plane in which the U-profile is closed down.

In one embodiment of the invention, the support structure includes stand elements for receiving the support rails, which are preferably provided for arrangement below the corners of the Belagtafeln.

These stand elements may include seats, preferably edge indentations, for receiving mounting rails, which are laid continuously over a plurality of stator elements. Advantageously, the support structure further comprises support rails which extend perpendicularly between the support rails which are laid continuously over a plurality of uprights.

These extending between the continuously installed mounting rails mounting rails are conveniently suspended from the stand elements.

In a further embodiment of the invention, the stand elements comprise a ver adjustable three- or four-point support for elevation on the subfloor. The adjustment may be effected by changing the height and inclination of the upright element e.g. by manipulation from above done by a tool is inserted from above into a sleeve into which a stand base is screwed with an engagement opening for the tool at the top.

In a further embodiment, the three- or four-point support may be adjustable by remote action through the laid cover panels, e.g. by magnetic action. For example, a via a magnetic coupling moved from the outside gearbox can be used for height adjustment. A readjustment of the finished floor covering is possible in such a way. Preferably, however, the support structure is precisely adjusted prior to laying the lining panels.

An adjustment can for example be possible by means of only one arranged at the intersection of the joints between the Belagtafeln screw. An insertion opening for a turning tool could be closed by means of a removable cap for adjustment. Also in this way can be done without removing Belagtafeln a readjustment of the flooring.

Preferably, the uprights elements are formed as cuboid open on one or two opposite sides, wherein the opposing parallelepiped walls at the free upper edge of an edge recess, in particular Randeinschlitzungen to form the above seat or to form means for suspending the support rails have.

The vertical stand elements can be easily set up alone. In this then the continuous over several stator elements, horizontally aligned mounting rails are used. Stops, especially Einschlitzungen it, can fix the exact position of the stator elements. Alternatively, the mounting rails may have markings for the position of the stator elements. Between two longitudinal beams produced in this way, the support beams, which are perpendicular thereto, can then be suspended from the support elements between two longitudinal rails forming support rails. This results in perfectly fitting square shots that pick up the lining panels provided with latching elements and clamp them together.

For bracing can also self-adjustment of the flooring and the Belagtafeln serve themselves, especially if there is room to move in the locking connections. The precisely fitting lining panels then adjust the bearing structure around the circumference and bring the support elements into their exact positions.

The extending between the continuous support rails shorter coupling carrier rails may have slots for hanging on the stator elements at their ends.

In the exemplary embodiment shown, a double floor construction comprises square covering panels 1, which are laid on the support structure at the edges in a contiguous manner. But it can also be used rectangular Belagtafeln, possibly omitting a hinged coupling carrier. The support structure raised on a subfloor comprises in each case under the corners of the adjoining lining panels 1 arranged stator elements. 2

On the uprights 2 mutually perpendicular support rails 3 and 4 are arranged, of which the support rails 3 each extend continuously over a plurality of stator elements 2 away and the support rails 4 only between two such support rails 3 and two stator elements 2.

As 6 and 7 Let the Belagtafeln 1 consist of several layers, a rigid carrier layer 5, a decorative layer 6 and an intermediate layer 7 foamed or molded onto the carrier layer 5 and the decorative layer 6. The rigid, the plaque stability providing carrier layer 5 is preferably made of a recycled material or a non-flammable, other material (eg a gypsum fiberboard or similar) produced. The decorative layer may have, for example, tiles or another material with a decorative surface. The foamed or injection-molded intermediate layer 7 is preferably made of polyurethane foam.

The intermediate layer 7 merges integrally into a peripheral rim 8 surrounding the covering panel 1, which forms a joint 9 with the edge enclosure of the respectively adjacent covering panel. Further, integrally connected to the intermediate layer 7 is a hook leg 10. Both the hook leg 10 and the edge enclosure 8 are made simultaneously with the intermediate layer 7 by foaming or molding. However, it is also possible to foam-in finished fasteners (for example extruded parts) as a substitute. In contrast to the peripheral edge enclosure 8, the hook legs 10 are not circumferentially interrupted but near the corners of the table.

The uprights 2 are essentially made as hollow cuboids with square horizontal cross-section and four side walls 11 which are open on opposite sides. The side walls 11 go over at the corners in each case in a vertical sleeve 12 with an internal thread. In the sleeves 12 stand feet 13 are screwed. Threaded bolts of the stand feet 13 expediently have at the upper end a recess for the engagement of a sleeve 12 insertable from above rotary tool. When producing the main body of the stator elements as extruded part, said internal threads are formed by press-fit sleeves.

Each of the side walls 11 has at the top two Randeinschlitzungen.

Both the continuous support rails 3 and the shorter support rails 4 in the example shown each consist of a U-shaped profile 15 made of steel and a profile 16 comprising a U-profile, which is e.g. made of aluminum or a plastic. An indentation 17 in the base leg of the steel profile 15 receives the profile 16, the base leg has a projection 18 on the outside. Further projections 19 are formed in the profile 16 on the inside at the ends of the U-legs. These are latching noses for engagement in a recess 20 in the hook leg 10. The latching noses form a second sealing plane.

The profiles 15, 16 could be deviated differently from a U-profile, and other materials than those mentioned may also be considered.

Both the mounting rails 3 and the support rails 4 have Randeinschlitzungen 21 in both legs of the U-profile 15.

In the production of a double floor construction from the components described above, first of all the stand elements 1 are arranged in the positions corresponding to the adjacent corners of the covering panels 1 on the underbody. Then, the laying of the continuous trough rails 3, the steel profiles 15 engage with their U-legs in the respective Randeinschlitzungen 14 in the side walls 11 of the support members 2. The slots 21 in the U-legs automatically ensure a dimensionally accurate arrangement of the support rails 3,4. Alternatively, instead of the slots 21 on the support rails 3 and / or 4, a mark could be attached, which facilitates a dimensionally accurate installation of the support structure, but by tolerance displacement can be compensated by longitudinal displacement of the support rails 3 and / or 4. Without on the dimensions of the lining panels tailored Einschlitzungen 21 or other the support rails 3.4 on the support elements 2 horizontally defining stops, can be variably adapted to different dimensions of Belagtafeln. Optionally, only the mounting rails 4 are adjusted.

The support structure can now be adjusted by horizontally aligning the support rails 3.4, the adjustable stand feet 13 of the stator elements 2 are adjusted by more or less wide screwing into the sleeves 12 so using a turning tool from above, so that each of the stator elements 2 is stable against tilting stands on the subsoil.

Finally, it is possible to assemble the lining panels 1 whose hook legs 10 fit into the e.g. be formed by the aluminum profile 16 formed channel, wherein the edges of the Belagtafeln 2 are pressed against each other and form the shock 9.

Finally, the panels are used under vertical pressure. The provided according to the dimensions of the Belagtafeln Einschlitzungen can have clearances such that the mounting rails in their position around the circumference follow the most accurate hook elements of Bellagafeln. Accordingly, the top surface formed by the lining panels ensures horizontal adjustment of the entire system.

The stand elements could also have such a height that, for example, a stage floor can be produced by the covering. This could be a firmer Coupling between the support rails and the stator elements, for example by screwing, can be provided.

Alternatively, transverse stiffeners, diagonal braces or the like could be provided, in particular at higher heights.

It will be up now Fig. 8 Reference is made where a further embodiment of a double floor covering is shown in sections. The same or equivalent parts are designated by the same reference number as in the preceding embodiment, the relevant reference number being accompanied by the letter a.

From the foregoing embodiment, the embodiment differs from FIG Fig. 8 especially by the fact that at opposite edge borders 8a of Belagtafeln 1 a further locking projection 22 and a locking recess 23 are provided.

The abutting edge pressure under pressure 8a form a first sealing plane. Finally, a downwardly closed U-profile 16a, in which lugs 10a of the edge surrounds 8a engage, as a third sealing barrier down no liquid through it.

In Fig. 9 and 10 a stator element 2b is shown, which has a lower part 25, which in its basic form the in Fig. 2 shown stator element 2 corresponds. The stand feet 13 corresponding stand feet are in the Figures 9 and 10 Not shown.

In each of four vertical sleeves 12b, a threaded bush 26 is rotatably inserted at its upper end.

In addition to the lower part 25, the stator element 2b has an upper part 27, which is formed in the horizontal cross section as the lower part 25 and at the upper edge (not shown) Einschlitzungen for the suspension of carrier rails are formed.

On a placed on the lower part 25 intermediate plate 28, a gear 29 is rotatably mounted, projecting axially from the Magnetkupptungseinrichtung 30.

The gear 29 is in engagement with four rotatably mounted on the intermediate plate 28 gears 31, which are each rotatably penetrated by a threaded bolt 32. Each of the threaded bolts 32 engages in one of the threaded bushes 26.

With the help of an in Fig. 10 shown magnetic rotary tool 33 can be carried out after installation of Belagtafeln 1 b height adjustment of the upper part 27 of the stator element 2b. Upon rotation of the magnetic coupling device 30 by the magnetic rotary tool 33, the gear 29 drives the four gears 31, so that the four threaded bolts 32 rotate and emerge from the threaded bushing 26 by raising the upper part 27. By left / right-hand thread an effect in both directions is possible.

Notwithstanding the embodiment shown, threaded bushes could also or only be provided on the upper part 27 or rotatably connected to the intermediate plate 28. It is understood that this requires appropriate combinations of right and left hand threads.

Notwithstanding the embodiment described above, the support rails 3.4 can be made in one piece, for example, from bent sheet steel. The FIGS. 11 to 13 show various embodiments of such support rails in cross section. The mounting rails each form a longitudinal channel 40 into which the hook legs formed on the edge sides of the Belagtafeln can be inserted.

The profile 16 of the above-described two-part mounting rails 3.4 could be made of aluminum instead of even better conductive copper, for example by pultrusion. In particular, such profiles can be used in conjunction with conductive Belagtafeln advantageous for the dissipation of electricity on the upper surface. The engaging in the longitudinal channel of the profile 16, integrally connected with the joint material hook legs can be formed, for example, of conductive polyurethane. Defined discharge currents can then flow via the profiles 16.

An in Fig. 14 shown transverse reinforcement 41 between extended stator elements 2a and 2a 'of a (not shown otherwise) stage floor, can be with the help of a in Fig. 15 Fasten each quick release at 42.

The quick-clamping comprises an outer tube 43 and an inner tube 44 guided in the outer tube 43, which is connected at one end to a clamping head 45. A in a recess 46 of the outer tube at 47 rotatably mounted toggle lever 48 engages with an Exenterkopf 49 in a recess 50 in the inner tube 44 a. By pivoting the toggle lever 48 as indicated by arrow 51, the clamping head 45, which engages behind the wall 52 and moves through an opening 53 in a wall 52 of the upright element 2a or 2a ', can move in the direction of the arrow 54 and the wall 52 between the front end of the outer tube 43 and pinch the clamping head 45.

By screwing longitudinally displaceable and so clamping constructions would also be possible.
