Surface elastic floor and mounting module

The invention relates to a surface-elastic floor according to the preamble of claim 1 and an assembly module for such a surface-elastic floor. Such a surface-elastic soil is under www.hamberger.de with the

The "Helsinki" sales designation, which consists in principle of an elastic layer laid out on a subfloor, on which a layer of load distribution elements consisting of plywood or OSB flat-pressed slabs is laid, is placed on top of this layer of load-distributing strips and floor elements made of high-quality parquet. The panels of the floor elements are executed on all sides with a tongue and groove connection, these panels are nailed in a transverse position on the pressure distribution strip and glued in the tongue / groove area.

A disadvantage of this floor is that a considerable installation effort is required on site at the construction site, since the laying of the elastic layer, arranged thereon pressure distribution strip and the parquet planks with the associated nailing and gluing requires several steps. A corresponding floor is also described in the patent DE 19 532 606 B4 of the applicant. In DE 20 2009 002 023 U1 a solution is proposed in which all elements of the floor, ie the elastic layer, the load distribution layer and the floor element are already glued together at the factory. Although this solution has the advantage that the installation on site due to the prefabricated elements can be done very easily. The disadvantage, however, is that the total thickness of such a prefabricated module is very large, so that at most five to seven elements can be inserted into a manageable packaging. Due to the elastic layer, however, these packages are not stable in position and thus relatively sensitive to damage. Another disadvantage is the extremely bulky packaging, which causes problems both during transport and on the construction site.

In contrast, the invention has for its object to provide a surface elastic see soil, which has a simple structure and can be laid in a simple manner.

This object is achieved by a surface-elastic base having the features of patent claim 1 and a mounting module having the features of the subordinate claim 12.

Advantageous developments of the invention are the subject of the dependent claims. According to the invention, the surface-elastic bottom has a bottom element, which consists of a plurality of planks, which are connected to one another via a profiling and which in turn are connected to a layer of at least one load distribution element. These are in turn on an elastic layer, which is designed to improve the damping on a subfloor. The elastic layer may be, for example, a foam or a vibrating carrier and in an alternative embodiment almost rigid or rigid.

According to the boards are connected to a prefabricated mounting module with load distribution elements, wherein the compound of the boards and the mounting modules with each other is formed at least longitudinally by an effective horizontal and vertical locking, which by Einwinkein and / or planar shifting with an adjacent floorboard or the neighboring one

Mounting module can be brought into engagement. In other words, the site is only the inventive

Assembly module consisting of a bottom element, one or more frontally or longitudinally with each other connected planks and a so

connected load distribution layer, consisting of one or a plurality of Load distribution plate designed on the delivered as a separate module elastic layer. The pre-assembly and packaging of the mounting modules is extremely easy due to the compact dimensions. Accordingly, the mounting module according to the invention with a

 Floor element running, with at least one load distribution plate

connected, in turn, with respect to side and front edges of the

Floor element is offset, with these sides and front edges

Connecting elements are formed, via which the bottom element or adjacent mounting modules in the horizontal and vertical directions can be locked.

These prefabricated mounting modules can reduce the assembly effort compared to conventional solutions to about 20% of the time required for this. In one embodiment of the invention, the bottom is formed along the end edges of a panel with a push-button connection provided with a vertical lock.

In a variant of the invention, the load distribution layer is formed by a plurality of load distribution plates, which are glued to the bottom element and / or connected thereto by fastening means, such as brackets, nails.

Alternatively, a single load distribution plate can be assigned to a mounting module. For better load distribution, it is provided according to the invention that at least one load distribution plate projects beyond one of the longitudinal edges and / or one of the end edges of the floor element (plank (s)) and is correspondingly spaced from the respective other longitudinal edge or end edge. When laying these mounting modules thus adjacent planks or mounting modules are supported together on one or more load distribution plate. In alternative embodiments, it is provided on a mounting module, the load distribution platelets with respect to the longitudinal and / or front edges of the bottom element recessed form and another, For this corresponding module assembly over the longitudinal and / or the end edges survive.

In one embodiment of the invention, it is preferable to make the load distribution plates approximately rectangular or square.

In this case, an edge length may be about 17 cm, with a parallel distance between the plates is less than 10 mm. This spacing ensures that the thermal resistance of the floor is considerably reduced in the case of underfloor heating, since the spacing of the load distribution platelets leads to specific heat conduction ducts. Another advantage of the prefabricated load distribution layer is the fact that, due to the regular spacing of the load distribution elements, a very even load transfer into the subfloor is ensured.

In one embodiment of the invention, the floor element consists of high quality parquet. Of course, other suitable materials may be used, such as a solid wood or laminate topcoat.

The floor is preferably used as a surface elastic sports floor.

As already explained, the mounting modules can be designed on an elastic layer, for example a foam layer or a vibration carrier. Such vibrating carrier sports floors are sold by the applicant, for example, under the name "Stockholm" or "Berlin". Such oscillating beams have a plurality of mutually parallel spring boards. These spring boards rest on spring elements made of plastic or the like, which in turn on

Rest underbody. In one embodiment of the invention adjacent to each other end load distribution plates of the mounting modules are aligned with respect to the spring boards, that is, the end portions of adjacent to each other

Lastverteilerplättchen are then each on a springboard arranged transversely thereto, so that the bottom is made sufficiently elastic. In a further development of the mounting module, it is provided that a single load distribution plate is associated with the floor element of this mounting module, which therefore extends approximately over the entire surface of the floor element and projects beyond a longitudinal edge and an end edge of the floor element.

According to the invention, it is preferred if, in the assembly module, at least one load distribution plate and the bottom element are glued together and / or clamped together.

A preferred embodiment of the invention will be explained in more detail below with reference to schematic drawings. Show it:

FIG. 1 shows a plan view of part of a mounting module 1 according to the invention of a sports hall floor, which will be explained later with reference to FIG. The Mon Tagemodul 1 consists essentially of a load distribution layer 2, on which in the view of Figure 1, a bottom element, in the present case, a floor element 4 is arranged from parquet. It is a high-quality two-layer or three-layer parquet, the latter having a Gegenzugschicht, a middle support layer and a usable surface forming top layer of parquet lamellae. One of these parquet slats 6 is highlighted in dashed lines in the illustration in FIG. In the illustrated embodiment, the bottom element 4 of a mounting module of a plurality of parquet elements, in the following planks 8, 10 composed, which are connected along their dash-dotted lines indicated end edges 12, 14 by a push-button connection according to Figure 4. Along the longitudinal edges 16, 18 a locking profile according to Figure 6 is formed, which will also be explained in the sequence. In one embodiment of the invention, the total length of such a mounting module 1 is about 2.40 m, while the width b is about 22 cm. The outer longitudinal and front edges of the boards 8, 10 also form the longitudinal and front edges of the mounting module. 1

The construction of the load distribution layer 2 can be seen from FIG. 2, which shows a view from below of the mounting module 1 in FIG. Accordingly, the load distribution layer 2 consists of a plurality of load distribution plates 20, which in the illustrated embodiment are made approximately square with an edge length of approximately 17 cm. The load distribution plates 20 are connected to the bottom element 4 in such a way that, in the illustrated embodiment, they protrude on the one hand over the longitudinal edges 16 of the boards 8, 10 and on the other hand are set back relative to the longitudinal edges 18 extending parallel thereto. The supernatant Ü of the load distribution plate 20 corresponds approximately to the dimension S, to which the platelets with respect to

Longitudinal edge 18 are reset. According to FIG. 2, in each case one of the platelets 20 also covers the connecting region of the two end edges 12, 14, so that practically two foot elements 4 are supported in sections on each platelet 20 and, accordingly, optimal load transfer is ensured.

The load distribution plate 20 are made of plywood in the illustrated embodiment. Alternatively, for example, HDF, OSB, another wood material or chipboard made load distribution plates 20 be used. As further seen in Figures 1 and 2, are the

Slide plate 20 at a distance a to each other. This spacing ensures that when laying the sports floor on a floor heating optimal heat transfer from the floor heating to the floor surface.

In one embodiment of the invention, the distance a is slightly less than 1 cm. The compound of one or more planks 8, 10 existing

 Floor element 4 with the load distribution layer 2, for example, by gluing and / or nailing, staples. In a concrete solution, the boards are connected to the load distribution layer by gluing and stapling, in Figure 2, the glue application area 21 is indicated by dashed lines. neighboring

Mounting modules are joined together by applying glue to the overhangs of the load distribution surfaces. The Applicant reserves the right to make its own claim to this type of gluing along the supernatants. This gluing / stapling is done at the factory, so that the finished assembly modules 1 are delivered to the site with the dimensions described above.

In the embodiments described above, the

Load distribution layer formed by a plurality of square load distribution plates 20. Instead of these square load distribution plates and rectangular shapes can be used, wherein along the longitudinal edges of the mounting module 1, 1 'extending edges of this rectangular

 Load distribution plate then, for example, twice the edge length of a square load distribution plate corresponds.

In a further variant of the invention, the bottom element 4 may be assigned a single load distribution plate, which protrudes laterally beyond a longitudinal edge and the front side over an end edge and practically supports the entire bottom element 4. However, such a version has a lower elasticity than those elements which consist of a plurality of load distribution platelets. Of course, geometries deviating from the square or rectangular shape can also be used.

FIGS. 3 and 4 show, in an enlarged view, the areas marked A and B in FIGS. 1 and 2. One recognizes in the figure 3 over the

Floor element 4 or more precisely on the longitudinal edges 16 of the planks 8, 10 out standing load distribution plate 20, the distance a to each other with the

Floor element 4 are connected and thereby also connected to each other

Cover end edges 12, 14.

The two interconnected end edges 12, 14 are clearly visible in the representation of Figure 4. It can also be seen that the longitudinal edge 18 lying at the top in this illustration stands by the dimension S beyond the parallel side edge of the load distribution platelets 20.

The profiling of the end edges 12, 14 of each floorboard 8, 10 and each mounting module 1 will be explained with reference to Figure 5, along the end edges 12, 14 connected boards 8, 10 from the viewing direction Y in Figure 4 shows. The connection shown in FIG. 5 is also used by the applicant in conventional floors for residential or commercial surfaces and is covered by the term "Top Connect®"

www, harn berger. de described. Further details of this frontal connection can also be found in the patent application WO 2010/075839 A1 of the Applicant, so that only the basic elements of the frontal connection essential for understanding the invention are explained here.

As shown in FIG. 5, a receiving groove 22 for a resilient locking element 24 is formed on the front edge 12. This protrudes from the end edge 12 of the board 8 and protrudes into a locking groove 26 at the end edge 14 of the other board 10 into it.

The arranged below the locking element 24 portion of the end edge 12 is extended to a lower lip 40 having at its end portion a projection 28 which in the locked state in a downgrade 30 of the other board. 8 dips. In this case, the locking element 24 rests on a surface 32 of the locking groove 26. A formed by the downgrade 30 locking projection 34 rests on the lower lip 40 and the locking projection 34 is engaged behind by the projection 28, so that the two planks 8, 10 are fixed in position in the horizontal direction and in the vertical direction.

The connecting of the floorboards takes place in that first a connection is made along the longitudinal edges (see FIG. 6) with an already installed floorboard and then the floorboard 10 is pivoted down onto a frontally adjacent, already installed floorboard 8, so that initially the locking projection 34 runs onto the locking element 24 and this resiliently urges back into the receiving groove 22, so that the locking projection 34 can be lowered onto the lower lip 40. Upon reaching this position then jumps the locking member 24 resiliently in the locking groove 26 back, so that a vertical locking takes place. Such push button connections can also be configured in other ways. The invention is therefore in no way limited to the described push-button connection.

According to Figure 5, the load distribution plates 20 are arranged on the underside of the boards 8, 10, which together form the bottom element 4 of a mounting module 1. The connection between two mounting modules 1 with each other along their end edges 12, 14 also takes place according to the embodiment in Figure 5. As already mentioned, in addition to the positive locking according to Figure 5, a positional fixation of the boards 8, 10 and / or interconnected

Assembly modules 1 done by gluing.

On the longitudinal side, a connection according to FIG. 6 is provided. This shows the longitudinal edges 16, 18 of two longitudinally interconnected mounting modules 1, 1 '(or planks 8, 10) in the viewing direction X of Figure 3.

The formed on the mounting modules longitudinal profile can be connected by Einwinkein with the corresponding longitudinal side of an already installed mounting module V. In principle, it is a tongue and groove connection with horizontal zontalverriegelung. Such a connection is marketed by the applicant under the name "Lock Connect®" and described, for example, under www.hamberger.de In principle, however, it is also possible to use another connection which can be connected, for example, by planar shifting in the horizontal direction Solution is described for example in DE 199 62 830 of the applicant.

In the known longitudinal side connection profile is on the longitudinal edge 16 of the bottom element 4 of a laying module V, a groove 36 with a

extended groove bottom lip 38 executed, which carries at its free end portion a horizontal locking projection 40. At the other longitudinal edge 18 and at the associated longitudinal edge 18 of the adjacent mounting module 1, a spring 42 is provided with a rounded end face 44, wherein the arranged below the spring 42 portion of the longitudinal edge 18 is downgraded and with a

Horizontal locking recess 46 is executed, in which the

Horizontal locking projection 40 can dip. In the illustrated

Locking position engages behind the horizontal locking projection 40 a

Inclined surface 48 of the Horizontalverriegelungsausnehmung 46, so that the two mounting modules 1, 1 'are locked in both the horizontal direction and in the vertical direction. As shown in Figure 6, the load distribution plate 20 overstretches the remaining gap 50 between the end edge of the groove bottom lip 38 and the

adjacent end face of the Horizontalverriegelungsausnehmung 46th

To attach the mounting module 1 to an already installed mounting module V, the spring 42 is placed with the rounded end face 44 on the extended groove bottom lip 38 in the arrow direction and then angled down so that the spring 42 dips into the groove 36 and the locking projection 40 in above Way the locking surface 48 engages behind.

FIG. 7 shows the construction of the area-elastic bottom 52 resulting from the installation of such assembly modules 1, 1 '. Two already installed assembly modules 1, 1' are shown along the longitudinally drawn dotted lines 16, 18 in FIG Way with each other. The longitudinal edge 16 of the mounting module 1 'with the over the longitudinal edge 16 beyond standing load Dividing plate 20 is not yet connected to another mounting module 1. It can be clearly seen, however, that at an angle of such a mounting module, this rests on the protruding portion of the load distribution plate 20. The mounting modules 1, 1 'rest on an elastic layer 54, which is placed on the lower floor. The elastic layer may be, for example, an organic

 Foam, which has a comparatively high density and a low compression set modulus. In an alternative embodiment, it is conceivable to form the elastic layer almost rigidly or rigidly. Figure 8 shows a variant in which the mounting modules not on a in the

 Substantive full-surface elastic layer, for example one

Foam layer are designed. In the variant shown in Figure 8, the mounting modules 1, 1 'are on a vibrating support 56, whose structure from the soils "Stockholm" and "Berlin" is known. In the illustration according to FIG. 8, a greatly simplified representation has been selected, from which only the layer structure can be removed, the profiling of the longitudinal and lateral edges is not shown. Again in this

Representation can be seen a partial area (in both the longitudinal and in the transverse direction) of a mounting module 1, which is placed on the oscillating support 56. This consists in principle of one or more mutually parallel spring boards 58, which in turn are supported by pad-shaped spring elements 60 made of plastic on the underbody. The spring boards 58 in turn consist of several individual elements which extend transversely to the assembly modules 1, 1 'in the illustration according to FIG. The a gap having joints between the

Load distribution plates 20 are aligned with respect to the spring boards 58, so that in each case two end portions of two adjacent

 Lastverteilerplättchen are supported on a respective spring board 58. The planks of the bottom element 4 then run correspondingly transverse to the spring boards 58. The connection of the mounting modules 1 with the oscillating support 56 takes place in the

illustrated embodiment by brackets 62, which are placed on both sides of the joints on the supernatant of the load distribution plate 20 on the bottom element 4. In this way is a reliable connection with the substructure

guaranteed. In addition, another gluing can take place. The

Load distribution plates 20 are not in the embodiment of FIG 8 square but rectangular in shape, the visible in Figure 8

Edge length corresponds to the distance b of two adjacent spring boards 58. The rearwardly extending in the figure 8 edge length of the modules 1 and the

Load distribution plate 20 is smaller, for example, about 50% of the dimension b.

Instead of the illustrated simple oscillating carrier and a double vibrating carrier can be used, in which two spring boards are arranged one above the other, which in turn are spaced apart by intermediate webs. Such a floor with Doppelschwingträger is sold by the applicant under the term "Berlin".

The frontal connection of the mounting modules 1, 1 'is effected by a push-button connection according to FIG. 5. The course of the end edges 12, 14 within a mounting module 1 or between adjacent mounting modules 1, 1' is shown by dashed lines in FIG.

For laying such a sports floor, the elastic layer 54 is first designed and then laid on the factory prefabricated mounting modules 1, 1 ', which are provided for example with a length of 2.40 m and a width of 22 cm. For this installation, the publisher needs only about 20% of the laying time, which he used to lay a conventional, input

described sports floor needed. Furthermore, the transport to

Construction site simplified because the prefabricated assembly modules 1, 1 'are very compact and not - as in the conventional solutions - in separate packaging units (parquet, load distribution plate) to be delivered and stored.

Disclosed is an elastic floor having a plurality of prefabricated mounting modules consisting of a, bottom element and at least one associated load distribution plate. These are delivered as a prefabricated unit to the construction site. LIST OF REFERENCE NUMBERS
