Description

The present invention relates to a floor, in particular terrace or balcony floor, according to the preamble of claim 1.

Such a floor is z. B. from the EP 1 739 252 B1 known. The known floor comprises a plurality of planks, each having a rectangular cross-section with two opposite longer sides and two opposite shorter sides, wherein the planks are arranged in a longitudinal direction of the floor parallel to each other and in a transverse direction of the bottom with a distance. The planks are in this case oriented such that one of the longer sides considered in cross-section, ie one of the "flat sides" of the planks are directed upwards and thus upwardly directed flat sides thus form a walk-surface of the soil.

In order to hold the planks in their mutual arrangement and mutual spacing, the known floor further comprises a substructure on which the planks are superimposed with their lower flat sides, as well as between adjacent widening planks used, in cross section W-shaped cover profiles, on the one hand attached to the substructure and on the other hand are used with lateral outer legs in corresponding grooves on the side surfaces of the planks.

The problem with known from the prior art generic floors, especially if the planks are made of lumber, their tendency to deform over time, such as caused by a "fading" and / or a "bowl" of the planks. In particular, in the case of the EP 1 739 252 B1 known soil is also the material and manufacturing costs associated with the required substructure and the cover profiles disadvantageous.

It is an object of the present invention to provide a novel construction for a floor of the type mentioned, by means of which in a simple manner a stable and deformation-free ground can be created over longer periods of use.

According to the invention this object is achieved in a soil of the type mentioned above in that the planks are oriented such that their upwardly directed sides are formed by one of the shorter sides of the cross section of the planks.

Due to the orientation of the planks according to the invention can advantageously be reduced the extent of any deformation phenomena, in addition, z. B. which is particularly problematic in known floor constructions bowl is no longer visible on the top of the floor.

Due to the novel construction in particular floors for outdoor surfaces such. B. balconies and terraces are much more stable, distortion-free and durable designed.

Advantageously, no complicated substructure structures are required in the ground according to the invention.

In particular, in a prefabrication of the floor or assembled at the place of use floor modules, the time required for installation of the soil is low. Depending on the static conditions, long distances from support to support can be bridged with the ground.

It is understood that the orientation of the planks provided in the invention as such is associated with a relatively high cost of materials and thus appears rather outlandish. However, it has surprisingly been found that this disadvantage is ultimately overcompensated in practice by the greatly increased durability of the soil according to the invention. In this context, it should also be borne in mind that a substructure, as provided for in known soils, is dispensable in the invention. Moreover, in the invention, the means for holding the planks in their mutual arrangement and in their mutual distance are relatively easy to implement.

The soil of the invention may, for. B. as a prefabricated floor module with z. B. at least 10, in particular z. B. at least 20 planks, which reduces the installation effort at the site accordingly.

The planks can z. B. have a length of at least 2 m, in particular at least 3 m. For logistical reasons (transport), a length of the planks of not more than 20 m, in particular not more than 15 m, is expedient in particular for prefabricated floor modules. Depending on the contour of the desired floor surface, the planks may have a uniform length or different lengths. Preferably, the planks have a uniform cross-section over their entire length (apart from the places where "holes" mentioned below are provided in the planks).

In a particularly preferred embodiment, the planks are formed from lumber (eg oak, ash, larch, etc.). Especially with such a natural material and use of the soil outdoors is relatively large However, because of the construction according to the invention, this ultimately does not entail any serious effects on the user.

However, it should not be ruled out in the context of the invention that the planks are formed of a different material, such as a wood-plastic composite material (eg., Mixture of wood flour, optionally additives and a thermoplastic material).

The planks have a substantially quadrangular cross-section with two opposite longer sides and two opposite shorter sides, including in particular also cross-sections, in which one or more corners are rounded or chamfered.

The terms "longer" and "shorter" (sides) are to be understood in the context of the invention in such a way that each of the longer sides is longer than each of the shorter sides.

In a preferred embodiment of the floor, the cross-section of the planks is in each case symmetrical to a vertical center line of the plank in question. In an optional further development, the cross-section of the planks is moreover symmetrical to a horizontal center line of the planks.

In one embodiment, the cross section is substantially rectangular, i. H. The four corners connect two (viewed in cross section) at a 90 ° angle to each other extending sides of the planks.

In another embodiment, the cross section is substantially trapezoidal, wherein the upwardly and downwardly directed sides of the trapezoidal shape preferably extend parallel to one another. In turn, the inner angle of the trapezoidal shape preferably deviates by a maximum of 20 °, in particular a maximum of 10 °, from the right angle (90 °).

In the case of a substantially rectangular cross-section as well as a substantially trapezoidal cross-section of the planks, one or more of the corners of the cross-section may be rounded or chamfered.

In one embodiment, for. B. rounded at least the two arranged to the top of the bottom corners or beveled. It can also z. B. all of the four corners of the cross-sectional shape of the planks should be rounded or chamfered. As regards the dimensioning of fillets, the cross-sectional area of the screed is preferably reduced by less than 5%, more preferably by less than 1%, compared to the corresponding non-rounded cross-sectional area.

In the following explanations concerning dimensions of the individual planks, lengths measured in the transverse direction of the floor are also referred to as "widths" and lengths measured in the vertical direction of the floor are also referred to as "heights".

The width of the planks on their upwardly directed side is preferably at least 2 cm, in particular at least 3 cm, and preferably at most 10 cm, in particular at most 8 cm.

The width of the planks on the downwardly directed side is preferably equal to or smaller than the width on the upwardly directed side. In one embodiment, the ratio of these two widths is in a range of 1: 1 to 1: 0.33, in particular in a range of 1: 1 to 1: 0.5.

The height of the planks is preferably at least 4 cm, in particular at least 6 cm, and preferably at most 15 cm, in particular at most 10 cm.

The ratio of the largest width of a screed (preferably on the upwardly facing side of the screed) to the highest height of the screed is preferably in a range of 1: 1.33 to 1: 3, in particular in a range of 1: 1.5 to 1: 2.

With regard to any existing rounding or chamfering at corners of the plank cross section, the ratios of dimensions given here are neglecting these rounding or chamfering to understand (that is, to be calculated as if no rounding or bevels are present).

The (clear) distance in the transverse direction of the floor between adjacent planks in the region of the upwardly directed sides of the planks is preferably at least 3 mm, in particular at least 5 mm, and preferably at most 15 mm, in particular at most 10 mm.

In one embodiment, for holding the planks in their mutual arrangement, a plurality of rods passing through the planks in the transverse direction of the floor are provided.

The rods can z. B. extend exactly in the transverse direction of the soil, wherein z. B. corresponding holes can be formed in the planks through which passes the respective rod. Preferably, the rods each extend with a small clearance (eg, smaller than 2 mm) through the respective bores of the planks.

In one embodiment, spacers between adjacent mutually extending planks are used to hold the planks in their mutual distance.

The spacers can, for. Example, have a sleeve-like shape, so that these can be advantageous also interspersed with the use of the aforementioned rods as the planks of the rods to keep the individual spacers reliable in their arrangement between adjacent extending planks. In this case, in particular hollow cylindrical sleeves can be provided, whose inner diameter is similar to the inner diameter of the mentioned holes of the planks adapted to the outer diameter of the rods to provide a preferably low clearance between the rods and the sleeve-shaped spacers.

In a further development of that embodiment in which sleeve-shaped spacers each interspersed with a rod are used, the bores of the planks are formed with a countersink in such a way that the end-side ends of the spacers in the transverse direction of the bottom are considered a distance (eg 1 to 5 mm) protrude into the planks, which further improves the stability when holding the planks in their mutual arrangement. The shape of the cuts is expediently adapted to the shape of the front ends of the spacers. In the case of hollow cylindrical spacers so far is a reduction with recessed, flat surface preferred as this z. B. after introduction of the holes can be subsequently produced with a Planenker.

The depth of the depression of the bore is preferably in a range of 0.05 times to 0.25 times the width of the screed present in the region of the depression.

In one embodiment, said bars and / or said spacers are formed from a metallic material (eg, stainless steel).

The transverse extent (diameter) of the rods can be suitably selected according to the mechanical stress to be expected when using the soil.

In one embodiment, the transverse dimension (diameter) of the rods is in a range of 5 mm to 20 mm.

In one embodiment, the transverse dimension (diameter) of the bars is in a range of 0.05 times to 0.2 times the height of the planks.

Also, a distance between the rods selected in the longitudinal direction of the bottom can be suitably selected according to the expected mechanical load. In many applications, the latter distance between the rods z. B. be useful in a range of 0.5 m to 1 m.

The mentioned rods can z. B. may be formed as threaded rods with an external thread to realize by screwing a nut at least one end of each threaded rod acting in the transverse direction of the soil fixing bracing of the planks with the spacers inserted therebetween.

If it comes in the course of time to fading or other deformations of the planks, so the floor z. B. be directed by suitable tightening the threaded rod fittings. In particular, in a symmetrical with respect to a horizontal plane shape of the floor is also considered, the floor after a long period of use simply turn over to use the previous bottom as a new top.

In some applications, it is desirable in the soil vertical passage of smaller objects or z. B. of water through the viewed in the transverse direction of the soil present gap between adjacent planks to avoid. In this case, appropriate, z. B. over the entire length of the soil extending filler or seals between adjacent extending planks are used.

In an advantageous development, the function of the mentioned spacers is simultaneously realized with such fillers. For this purpose, z. B. be provided that the filler bodies are clamped or braced using the aforementioned rods, in particular threaded rods, each between two adjacent planks. The fillers can hereby be provided with corresponding recesses (eg bores) in the region of the rods, in order to allow the passage of the rods.

In an embodiment which is particularly suitable for waterproofing and which is particularly advantageous in terms of the cost of materials, the filler bodies are essentially designed as profiles running in the longitudinal direction of the floor (eg of metal such as stainless steel or plastic), these profiles each comprising: a vertically extending and recesses for the passage of the rods having web portion, which preferably extends at least approximately in the middle of the gap between the adjacent planks, and at the two Vertical ends of this web portion arranged horizontally extending profile sections, which fulfill both the spacer function and the sealing function. The lateral ends of these profile sections can, for. B. abut directly on the adjacent planks.

In an embodiment variant of the floor, the accessible area is formed by the upwardly directed sides of the planks themselves.

In another embodiment variant, the walk-on area is formed by separately produced cover strips which are (directly or indirectly) attached to the upwardly directed sides of the planks.

The attachment of the cover strips can, for. B. be accomplished by a screw and / or bonding with the planks. Advantageously, a structuring of the upwardly directed sides of the planks in combination with a corresponding structuring of undersides of the cover strips can be provided at this point in order to realize an (additional) positive connection and / or a contact surface enlargement which is advantageous with regard to bonding. As such structuring is in particular z. B. at least one extending in the longitudinal direction of the bottom elevation on the upwardly directed side of the screed (or the downwardly directed side of the cover strip) in combination with a corresponding groove on the downwardly directed side of the cover strip (or the upwardly directed side the screed) into consideration.

In view of a simple installation of the soil z. B. on concrete or other solid substrates can z. B. height-adjustable feet can be provided on the underside of the floor. For this purpose, various designs come into consideration within the scope of the invention. In a particularly advantageous embodiment, the bottom is provided with a plurality of adjustable feet, each comprising a vertically extending threaded rod extending in the region of a gap between adjacent planks, is preferably provided at its lower end with a plate-shaped support member for resting on the ground, and at its upper end suitable for attacking a tool head (especially eg hexagon socket, Torx or the like), so as to accomplish a height adjustment by rotation of the threaded rod, wherein in the region of the downwardly facing sides of both sides of the threaded rod adjacent Planks a bearing plate rests on the downwardly facing sides of the planks and is fixed there, and wherein said bearing plate has an internally threaded bore with which a shaft portion of the threaded rod is engaged.

A preferred use of the floor is to use it outdoors.

In a preferred use of the floor, it is provided that the minimum distance between two supports (eg mentioned leveling feet) of the floor is greater than 1 m, in particular greater than 2 m.

In one embodiment of the use of the floor, provision is made for a self-supporting overhang of the floor starting from the bearing surface defined ("clamped") by the position of the supports in at least one direction (eg longitudinal direction and / or transverse direction) a projection length of more than 0.3 m, in particular more than 0.6 m is provided.

In one embodiment, the use of the bottom of this is supported on two lateral edge regions in each case by a plurality of supports, wherein a minimum distance between the two support surfaces defined by the respective support surfaces is greater than 2 m, in particular greater than 3 m.

For example, at a desired width of the soil 10 of about 2 m could be the soil shown 10 z. B. about 30 to 70 planks 12 exhibit.

Also considered in the longitudinal direction L present length of the soil 10 can z. B. on the order of one or several meters. The length of the floor viewed in the longitudinal direction L may be uniform, but may also vary across the transverse direction (planks of different lengths).

The planks 12 have one by the mutual distance of the respective longer sides 14 defined width b and one by the mutual distance of the respective shorter sides 16 defined height h.

A special feature of the soil 10 is that the planks 12 are oriented such that their upwardly directed sides, on which the walk-in bottom surface is formed, of one of the two shorter sides 16 the cross-section of the planks 12 are formed. It therefore applies h> b.

The distance d between adjacent planks 12 is preferably selected uniform over the entire bottom width and in the illustrated embodiment z. B. 8 mm. Particularly preferably, the distance d is in the range of 5 mm to 10 mm.

If desired, cross-sectional corners of the planks 12 , such as In 1 also shown, bevelled (alternatively rounded).

To hold the planks 12 in their mutual arrangement and in their mutual distance d more are the planks 12 in the transverse direction Q of the ground 10 penetrating threaded rods 18 provided, in the example shown exactly in the transverse direction Q by appropriately arranged holes 20 the planks 12 run.

Between adjacent planks 12 are each hollow cylindrical spacer sleeves 22 inserted, each from one of the threaded rods 18 to be interspersed.

In the sectional view of 1 is just one of the threaded rods 18 to recognize.

Conveniently, the threaded rods 18 with a mutual distance considered in the longitudinal direction L of typically about 0.2 m to 1 m over the entire length of the soil 10 arranged distributed.

An optional feature of the presented floor 10 is also that the holes 20 are each provided at their bore mouths with a few mm deep depression, in which the front ends of the spacer sleeves 22 are used.

The arrangement of the planks 12 with the interposed spacer sleeves 22 is fixed or braced by on each threaded rod 18 At the two ends screwed clamping nuts, of which in 1 one obvious and with 24 As an alternative to the use of clamping nuts on both ends of a rod, for example, one end of the rod could be provided with a fixed "head" and only the other end with an external thread and clamping nut).

The walk-in area of the floor 10 in the example shown, it is the up-facing pages 16 the planks 12 self-educated. If desired, these pages 16 be designed for aesthetic reasons and / or with regard to a desired slip resistance with a structuring. For this purpose, in particular in the longitudinal direction L continuous grooves, z. B. rectangular grooves, or z. B. a wave-like corrugation into consideration.

Another optional feature of the presented floor 10 is that this is equipped at desired points with feet, of which in 1 one obvious and with 26 is designated.

In the example shown, the adjustable foot comprises 26 a threaded rod 28 , at the lower end of a support plate 30 is mounted (preferably rotatable about a longitudinal central axis of the threaded rod). The threaded rod 28 projects upwards into a gap between two adjacent planks 12 into it, with an external thread of the threaded rod 28 in engagement with an internal thread of a bearing plate 32 which stands at the bottom of the floor 10 the gap between the two planks concerned 12 bridging at these planks 12 is fastened (eg by a screw connection as in 1 indicated).

The floor 10 can be advantageous z. B. as a prefabricated floor module ("floor mattress") in whole (to be joined together at the site) units or trains are made to measure.

In the following description of further embodiments, the same reference numerals are used for equivalent components, each supplemented by a small letter to distinguish the embodiment. In this case, essentially only the differences from the embodiment (s) already described are discussed and, moreover, reference is hereby explicitly made to the description of previous exemplary embodiments.

2 shows a floor 10a , for the sake of simplicity again only four planks 12a are shown and beyond the arrangement of a threaded rod 28a is shown simplified.

An essential difference of the soil 10a opposite the already described ground 10 ( 1 ) is that at the bottom 10a no sleeve-shaped spacers (spacer sleeves 22 in 1 ) are provided, but between adjacent mutually extending planks 12a in each case one in the longitudinal direction L extending sealing and spacer profile 40a is used.

For the passage of the threaded rods 28a are appropriately arranged holes in the profiles 40a educated.

Every profile 40a comprises a vertically extending and recesses for the passage of the rods having web portion 42a which is in the middle of the gap between the adjacent planks 12a runs, as well as at the two vertical ends of this web section 42a arranged, horizontally extending profile sections 44a which fulfill both the spacer function and the sealing function. In this respect, it is the profile 40a in the example shown, a "double-T" or "I" profile. The lateral ends of the profile sections 44a lie directly on the neighboring planks 12a (Alternatively, the profile sections 44a also partially in corresponding grooves of the planks 12a be sunk).

The profile is preferred 40a , as in 2 also shown, dimensioned and arranged so that its profile sections 44a not flush with the up or down facing sides of the planks 12a but in high direction H considered within the gap between the planks 12a run out, leaving at the top of the floor 10a corresponding "water drainage channels" are formed.

The example shown in FIG 2 (as well as 1 ) Preliminary symmetry of the soil 10a with respect to a horizontal median plane has the advantage that (for example, after prolonged use) the arrangement of the planks 12a together with profiles 40a can also be turned 180 ° (turned around).

3 shows a floor 10b in one of the 1 corresponding representation, wherein in the partial representation of 3 again only four planks 12b are drawn.

An essential difference between the floor 10b and the already described soils 10 and 10a ( 1 respectively. 2 ) is that the individual planks 12b have a substantially trapezoidal cross section, said cross section again two opposite longer sides 14b and two shorter sides opposite each other 16b owns, with the shorter sides 16b running parallel to each other an upper side (walk-surface of the soil 10b ) and a bottom of the floor 10b training, whereas the longer sides 14b not parallel to each other, so that a width of the planks 12b downsized from top to bottom.

In 3 is one at the walkable area of the ground 10b existing width of the planks 12b labeled b1 and one at the bottom of the planks 12b existing width designated b2. In the example shown, b2 is about 0.5 times that of b1.

With the embodiment according to 3 is compared to the statements according to 1 and 2 advantageous material (for the planks 12b Saved.

4 shows a part of a floor 10c namely a screed intended for the formation of the same 12c where the ground 10c through a like already described juxtaposition of a variety of such planks 12c is formed.

The planks 12c have a substantially rectangular cross section with a height h and a width b.

An essential difference of the soil 10c Compared to the previously described embodiments is that the walk-in area of the floor 10c not from the up-facing pages 16c itself is formed, but the walk-in area of cover strips 50c is formed on the upwardly directed sides 16c the planks 12c are attached.

The cover strips 50c are in the example shown with the planks 12c bonded. A structuring is advantageous (here: longitudinal elevation) of the upwardly directed sides 16c the planks 12c and a corresponding structuring (in this case: longitudinal groove) engaged therewith from undersides of the cover strips 50c provided in order to achieve an additional form-fitting connection and a contact surface enlargement which is advantageous for the bonding.

Because the cover strips 50c have a width b which is greater than a width b of the planks 12c is, with the embodiment according to 4 in comparison to the statements according to the 1 and 2 again advantageous material for the planks 12c saved. In general, a "lateral overhang"b'-b is preferably in a range of 0.75 times to 1.5 times the width b (or if the planks in question do not have a uniform width b, the width of the planks on their upward side). A relevant for the user of the soil (clear) distance between transversely adjacent cover strips 50c is preferably in a range of 5 mm to 10 mm. Due to the mentioned overhang of the cover strips 50c is then the distance between the adjacent planks 12c correspondingly larger.

5 illustrates an application example of a floor 10d of the type described here.

The floor 10d is essentially like the ground 10 ( 1 ), but waived height adjustable adjustable feet and instead a direct Auflagerung of planks 12d on transversely extending Q carrier 60 (eg made of wood) is provided. The carriers 60d are in turn at their ends and possibly at other points of their course on vertically in a ground 62d used piles 64d (eg round logs made of oak).

Starting from the in 5 to the left "last Auflagerung" by the in 5 left carrier 60d is bottom to the left end 10d provided a cantilevered overhang, which is dimensioned by about 0.5 m cantilevered.

6 illustrates another example of use for a floor 10e of the type described here.

In this example, the bottom is 10e at his in 6 left end up on a garage roof and at his in 6 right end attached to a house facade. Between these two relatively widely spaced support areas extends a longitudinal area L viewed in the middle region of the soil 10e self-supporting.
