Abstract

An elastic floor is disclosed which has a plurality of prefabricated assembly modules consisting of a floor element and at least one load distribution plate connected to it. These are delivered to the construction site as a prefabricated unit.

Description

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 offered under the sales designation "Helsinki" and consists in principle of an elastic layer laid out on a subfloor on which a layer of load distribution elements made of plywood or OSB flat-pressed plates is laid. Floor elements made of high quality parquet are then placed on this layer of load distribution strips in the transverse direction. 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 bottom is also in the patent DE 19 532 606 B4 the applicant described.

In the 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 soil, which has a simple structure and can be laid in a simple manner.

This object is achieved by a surface-elastic base with the features of claim 1 and a mounting module with the features of the independent 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 invention the boards are connected to a prefabricated mounting module with load distribution elements, wherein the connection of the boards and the mounting modules with each other is formed at least longitudinally by an effective horizontal and vertical locking, which by Einwinkeln and / or planar shifting with an adjacent floorboard or the adjacent mounting module can be brought into engagement.

In other words, the construction site is merely the assembly module according to the invention consisting of a bottom element, one or more frontally or longitudinally interconnected planks and an associated load distribution layer, consisting of one or a plurality of load distribution plates on the delivered as a separate module elastic layer designed. 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 is carried out with a bottom element which is connected to at least one load distribution plate, which in turn is offset with respect to side and front edges of the bottom element, wherein on these sides and end edges connecting elements are formed, via which the bottom element or adjacent mounting modules in Horizontal and vertical direction 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 connected to the bottom element glued and / or connected to this 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 plates with respect to the longitudinal and / or front edges of the bottom element formed back and leave in another, corresponding thereto mounting module over the longitudinal and / or the end edges.

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 uniform load transfer is ensured in the subsoil inside.

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 rest on the underbody. In one embodiment of the invention, mutually adjacent load distribution plates of the mounting modules are aligned with respect to the spring boards to each other, that is, the end portions of adjacent Lastverteilerplättchen then each lie 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:

1 shows a plan view of a part of a mounting module according to the invention 1 a sports hall floor, later based 7 is explained. The mounting module 1 consists essentially of a load distribution layer 2 , in the view according to 1 a floor element, in the present case a floor element 4 is arranged from parquet. This is a high-quality two-layer or three-layer parquet, the latter a Gegenzugschicht, a middle support layer and Having a useful surface forming top layer of parquet lamellae. One of these parquet slats 6 is in the illustration according to 1 dashed highlighted. In the illustrated embodiment, the bottom element 4 a mounting module made of a variety of parquet elements, hereafter planks 8th . 10 composed along their dash-dotted lines indicated end edges 12 . 14 by a push-button connection according to 4 are connected. Along the long edges 16 . 18 is a locking profile according to 6 trained, which is also explained in the episode. In one embodiment of the invention, the total length of such a mounting module 1 about 2.40 m, while the width b is about 22 cm. The outer longitudinal and front edges of the planks 8th . 10 also form the longitudinal and front edges of the mounting module 1 ,

The structure of the load distribution layer 2 opens up 2 taking a bottom view of the mounting module 1 in 1 shows. Accordingly, there is the load distribution layer 2 from a variety of load distribution tiles 20 , which are executed approximately square in the illustrated embodiment with an edge length of about 17 cm. The load distribution tiles 20 are like that with the floor element 4 connected in the illustrated embodiment on the one hand over the longitudinal edges 16 the planks 8th . 10 protrude and on the other hand against the longitudinal edges running parallel thereto 18 are reset. The supernatant Ü of the load distribution platelets 20 corresponds approximately to the dimension S, to which the platelets with respect to the longitudinal edge 18 are reset. According to 2 covers one of the tiles in each case 20 also the connection area of the two front edges 12 . 14 so practically on every slide 20 two floor elements 4 are partially supported and accordingly an optimal load transfer is guaranteed.

The load distribution tiles 20 are made of plywood in the illustrated embodiment. Alternatively, for example, from HDF, OSB, another wood material or chipboard made load distribution plates 20 be used. How to continue the 1 and 2 is removable, are the platelets 20 moved 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 connection of one or more planks 8th . 10 existing floor element 4 with the load distribution layer 2 for example, by gluing and / or nailing, parentheses. In a concrete solution, the boards are connected to the load distribution layer by gluing and clamping, in 2 is the glue application area 21 indicated by dashed lines. Adjacent 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 supplied with the above dimensions to the site.

In the embodiments described above, the load distribution layer is defined by a plurality of square load distribution plates 20 educated. Instead of these square load distribution plates and rectangular shapes can be used, which along the longitudinal edges of the mounting module 1 . 1' then extending edges of this rectangular load distribution plate then, for example, the double edge length of a square load distribution plate corresponds.

In a further variant of the invention, the floor element 4 be associated with a single load distribution plate which projects laterally over a longitudinal edge and the end face over a front edge and virtually the entire floor element 4 supported. 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.

The 3 and 4 show the in the 1 and 2 A and B marked areas in an enlarged view. One recognizes in 3 the over the floor element 4 or more precisely on the longitudinal edges 16 the planks 8th . 10 out standing load distribution plate 20 at a distance a to each other with the floor element 4 are connected and thereby also the interconnected end edges 12 . 14 cover.

The two connected front edges 12 . 14 are in the illustration according to 4 clear to see. It can also be seen that the longitudinal edge lying in this illustration above 18 by the dimension S over the parallel side edge of the load distribution platelets 20 stands out.

The profiling of the front edges 12 . 14 every hallway 8th . 10 and every mounting module 1 is based 5 explained along the front edges 12 . 14 connected planks 8th . 10 from the viewing direction Y in 4 shows. In the 5 illustrated Connection is used by the applicant in conventional flooring for residential or commercial space and is under the term "Top Connect ^® " under www.hamberger.de described. Further details of this frontal connection are also the patent application WO 2010/075839 A1 can be removed from the applicant, so that only the essential elements of the frontal connection essential for understanding the invention are explained here.

As shown in 5 is at the front edge 12 a receiving groove 22 for a resilient locking element 24 educated. This protrudes from the front edge 12 the hall 8th out and protrudes into a locking groove 26 at the front edge 14 the other hallway 10 into it.

The below the locking element 24 arranged area of the front edge 12 is to a lower lip 40 extended, which at its end portion a projection 28 has in the locked state in a downgrade 30 the other hallway 8th dips. This is the locking element 24 on an area 32 the locking groove 26 on. One by the demotion 30 trained locking projection 34 lies on the lower lip 40 on and the locking tab 34 gets off the lead 28 engaged behind, leaving the two planks 8th . 10 are fixed in position in the horizontal direction and in the vertical direction.

The bonding of the floorboards takes place in that first a connection along the longitudinal edges (see 6 ) is made with a previously laid floorboard and then the hallway 10 on a frontally adjacent, already laid plank 8th is pivoted down, so first the locking projection 34 on the locking element 24 runs up and this elastic in the receiving groove 22 pushes back, leaving the locking projection 34 on the lower lip 40 can be lowered. Upon reaching this position then jumps the locking element 24 resilient 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 5 are at the bottom of the floorboards 8th . 10 , who share the floor element 4 a mounting module 1 form the load distribution tiles 20 arranged. The connection of two mounting modules 1 with each other along their front edges 12 . 14 also takes place according to the embodiment in 5 , As already mentioned, in addition to the positive locking according to 5 a position fixation of the planks 8th . 10 and / or the interconnected mounting modules 1 done by gluing.

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

The formed on the mounting modules longitudinal profile can be made by angling with the corresponding longitudinal side of an already installed mounting module 1' get connected. In principle, it is a tongue and groove connection with horizontal locking. Such a compound is marketed by the Applicant under the term "Lock Connect ^® " and, for example, under www.hamberger.de described. In principle, however, it is also possible to use another connection which can be connected, for example, by planar shifting in the horizontal direction. Such a solution is for example in the DE 199 62 830 the applicant described.

In the known longitudinal side connection profile is at the longitudinal edge 16 of the floor element 4 a laying module 1' a groove 36 with an extended groove lower lip 38 executed, which at its free end portion a horizontal locking projection 40 wearing. On the other longitudinal edge 18 or at the associated longitudinal edge 18 of the adjacent mounting module 1 is a spring 42 with a rounded face 44 provided, with the below the spring 42 arranged region of the longitudinal edge 18 is downgraded and with a Horizontalverriegelungsausnehmung 46 is executed, in which the horizontal locking projection 40 can dive. In the illustrated locking position, the horizontal locking projection engages behind 40 an oblique surface 48 the horizontal locking recess 46 so the two mounting modules 1 . 1' are locked in both the horizontal direction and in the vertical direction. As shown in 6 overstretches the load distribution tile 20 the remaining gap 50 between the front edge of the groove bottom lip 38 and the adjacent end face of the horizontal lock recess 46 ,

For attaching the mounting module 1 to an already installed mounting module 1' becomes the spring 42 with the rounded end face 44 on the extended groove lower lip 38 placed in the direction of the arrow and then angled down so that the spring 42 in the groove 36 dips and the locking projection 40 in the manner described above, the locking surface 48 engages behind.

7 shows in the installation of such mounting modules 1 . 1' resulting structure of the surface elastic soil 52 , You can see two already installed assembly modules 1 . 1' along the dash-dotted lines 16 . 18 in the in 6 described way with each other are connected. The longitudinal edge 16 of the mounting module 1' with the over the long edge 16 out standing load distribution plate 20 is not yet with another mounting module 1 connected. However, it can be clearly seen that, when an assembly module of this kind is angled, it projects onto the protruding section of the load distribution platelets 20 rests. The mounting modules 1 . 1' lie on an elastic layer 54 on, which is placed on the subfloor. The elastic layer may be, for example, an organic foam having 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.

8th shows a variant in which the mounting modules are not designed on a substantially full-surface elastic layer, such as a foam layer. At the in 8th variant shown are the mounting modules 1 . 1' on a swinging carrier 56 whose structure is known from the soils "Stockholm" and "Berlin". In the illustration according to 8th was chosen a greatly simplified representation, from which only the layer structure can be removed, the profiling of the longitudinal and lateral edges is not shown. Again in this representation one sees a partial area (both in the longitudinal and in the transverse direction) of a mounting module 1 who is on the swinging carrier 56 is up. This consists in principle of one or more mutually parallel spring boards 58 , in turn, over pad-shaped spring elements 60 made of plastic are supported on the underbody. The springboards 58 consist in turn of several individual elements in the representation according to 8th across to the mounting modules 1 . 1' extend. The a gap having joints between the load distribution plate 20 are related to the spring boards 58 aligned, so that in each case two end sections of two adjacent Lastverteilerplättchen on each a spring board 58 are supported. The planks of the floor element 4 then run accordingly across the spring boards 58 , The connection of the mounting modules 1 with the vibrating carrier 56 takes place in the illustrated embodiment by brackets 62 , on both sides of the joints on the supernatant of the load distribution plates 20 above the floor element 4 are set up. In this way, a reliable connection with the substructure is ensured. In addition, another gluing can take place. The load distribution tiles 20 are in the embodiment according to 8th not square but rectangular, with the in 8th visible edge length the distance b of two adjacent spring boards 58 equivalent. They are in the 8th rearward extending edge length of the modules 1 and the load distribution plate 20 is less, for example, about 50% of the measure 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' done by a push-button connection according to 5 , The course of the front edges 12 . 14 within a mounting module 1 or between adjacent mounting modules 1 . 1' is in 7 dashed lines.

For laying such a sports floor, first, the elastic layer 54 designed and then on the factory prefabricated mounting modules 1 . 1' laid, for example, with a length of 2.40 m and a width of 22 cm are provided. For this installation, the publisher needs only about 20% of that laying time, which he needs for laying a conventional sports floor described above. Furthermore, the transport to the site is 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 load distribution plate associated therewith. These are delivered as a prefabricated unit to the construction site.
