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.). In particular, in such a natural material and use of the soil outdoors is expected to relatively high tendency to deform, but ultimately brings due to the construction of the invention, no serious consequences for the user with it.

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 beveled 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, the inner diameter similar to the Inner diameter of said holes of the planks is 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 arranged at the two vertical ends of this web portion, 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 downward sides of the planks and is attached 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.

Fig. 1 shows a floor 10, for example, for laying on a terrace or a balcony, with several planks 12 of lumber (here eg oak), each having a substantially rectangular cross section with two opposite longer sides 14 and two opposite shorter sides 16, wherein the planks 12 are arranged in a longitudinal direction L of the bottom 10 parallel to each other and in a transverse direction Q of the bottom 10 at a distance d to each other, and wherein formed on upwardly facing sides of the planks 10 a walk-surface of the bottom 10 is. A vertical or vertical direction is in Fig. 1 denoted by H.

Fig. 1 shows for simplicity only the starting from a in Fig. 1 The actual number of planks 12 is basically arbitrary and can be selected according to the width of the bottom 10 required in the transverse direction Q. For example, with a desired width of the bottom 10 of about 2 m, the bottom 10 shown z. B. about 30 to 70 planks 12 have.

Also considered in the longitudinal direction L present length of the bottom 10 may, for. 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 a width b defined by the mutual distance of the respective longer sides 14 and a height h defined by the mutual distance of the respective shorter sides 16.

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

The distance d between adjacent planks 12 is preferably chosen uniform over the entire bottom width and is in the illustrated embodiment, for. 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 Fig. 1 also shown, bevelled (alternatively rounded).

For holding the planks 12 in their mutual arrangement and in their mutual distance d a plurality of the planks 12 in the transverse direction Q of the bottom 10 passing through threaded rods 18 are provided which extend exactly in the transverse direction Q through correspondingly arranged holes 20 of the planks 12 in the example shown.

Between adjacent mutually extending planks 12 respectively hollow cylindrical spacer sleeves 22 are inserted, which are penetrated in each case by one of the threaded rods 18.

In the sectional view of Fig. 1 only one of the threaded rods 18 can be seen.

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

An optional feature of the illustrated base 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 intermediate spacer sleeves 22 is fixed or braced by screwed to each threaded rod 18 at its two ends Clamping nuts, of which in Fig. 1 one visible and designated 24 (Alternatively to the use of locknuts at both ends of a bar, one end of the bar could also be provided with a fixed "head" and only the other end with an external thread and nut).

The accessible area of the floor 10 is formed in the illustrated example of the upwardly directed sides 16 of the planks 12 itself. If desired, these sides 16 may be formed 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 illustrated floor 10 is that it is provided at desired locations with feet, of which in Fig. 1 one can be seen and designated 26.

In the illustrated example, the adjustable foot 26 comprises 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 protrudes upward into a gap between two mutually adjacent planks 12, wherein an external thread of the threaded rod 28 is in engagement with an internal thread of a bearing plate 32, which bridges the gap between the two relevant planks 12 at the bottom of the bottom 10 attached to these planks 12 (eg, by a screw connection as in Fig. 1 indicated). The bearing plate 32 has an approximately square contour in the example shown. By this construction, a height adjustment of the adjustable foot 26 can be accomplished by a corresponding rotation of the threaded rod 28. In the example shown, the upper end of the threaded rod 28 is suitably shaped for this purpose tool engagement, ie z. B. provided with a hexagon socket or the like.

Due to the illustrated construction of the bottom 10 and the thus realized connection of "standing timber" (planks 12) can be advantageous z. B. external surfaces such as balconies and terraces are much more stable, distortion-free and durable designed.

The standing wood arranged in their connection with each other have a lower tendency to shrinkage and a lower tipping and cracking compared to conventionally laid board.

The bottom 10 may advantageously 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.

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

A significant difference of the bottom 10a compared to the already described bottom 10 (FIG. Fig. 1 ) is that at the bottom 10 a no sleeve-shaped spacers (spacer sleeves 22 in Fig. 1 ) are provided, but between each adjacent extending planks 12a each extending in the longitudinal direction L sealing and spacer profile 40a is inserted.

For the passage of the threaded rods 28a correspondingly arranged holes in the profiles 40a are formed.

Each profile 40a. Comprises a vertically extending and passageways for the passage of the bars having web portion 42a, which runs in the middle of the gap between the adjacent planks 12a, and arranged at the two vertical ends of this web portion 42a, horizontally extending profile sections 44a, which both Perform spacer function and the sealing function. In this respect, the profile 40a in the example shown is a "double T" or "I" profile. The lateral ends of the tread portions 44a abut directly on the adjacent planks 12a (alternatively, the tread portions 44a could also be partially buried in corresponding grooves of the planks 12a).

Preferably, the profile 40a is as in Fig. 2 also shown, dimensioned and arranged so that its profile sections 44a not flush with the upwardly or downwardly directed sides of the planks 12a, but viewed in the vertical direction H within the gap between the planks 12a extend, so that at the top of the bottom 10a corresponding "water drainage channels" are formed.

The example shown in FIG Fig. 2 (as well as Fig. 1 1) has the advantage that (eg after prolonged use) the arrangement of the planks 12a together with profiles 40a can also be turned over (turned over) by 180 ° with respect to a horizontal center plane.

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

A significant difference between the bottom 10b and the already described bottoms 10 and 10a (FIG. Fig. 1 respectively. Fig. 2 ) is that the individual planks 12b have a substantially trapezoidal cross-section, this cross-section again has two opposite longer sides 14b and two opposite shorter sides 16b, wherein the shorter sides 16b parallel to each other a top (walkable surface of the bottom 10b) and a lower surface of the bottom 10b, whereas the longer sides 14b are not parallel to each other, so that a width of the planks 12b decreases from top to bottom.

In Fig. 3 a width of the planks 12b present on the walk-on surface of the floor 10b is designated by b1, and a width at the lower end of the planks 12b is designated by b2. In the example shown, b2 is about 0.5 times that of b1.

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

Fig. 4 shows a part of a bottom 10c, namely a screed 12c provided for forming the same, the bottom 10c being formed by a row of a plurality of such screeds 12c, as already described.

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

A significant difference of the bottom 10c compared to the previously described embodiments is that the walk-in surface of the bottom 10c is not formed by the upwardly directed sides 16c itself, but the walk-in surface is formed by cover strips 50c, which at the top directed sides 16c of the planks 12c are mounted.

The cover strips 50c are glued in the example shown with the planks 12c. Advantageous is a structuring (in this case: longitudinal elevation) of the upwardly directed sides 16c of the planks 12c and a corresponding structuring (in this case longitudinal groove) provided therefrom, provided by undersides of the cover strips 50c in order to provide an additional positive connection and one advantageous for the bonding To achieve contact surface enlargement.

Since the cover strips 50c have a width b 'that is greater than a width b of the planks 12c, the embodiment according to FIG Fig. 4 in comparison to the statements according to the Fig. 1 and Fig. 2 again advantageously saved material for the planks 12c. 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 (light) distance that is relevant for the user of the floor between crosswise adjacent cover strips 50c is preferably in a range of 5 mm to 10 mm. Due to the above-mentioned overhang of the cover strips 50c, the distance between the mutually adjacent planks 12c is correspondingly greater.

Fig. 5 illustrates an example of use of a bottom 10d of the type described here.

The bottom 10d is essentially like the bottom 10 (FIG. Fig. 1 ), wherein, however, height-adjustable adjusting feet are dispensed with and instead a direct support of planks 12d on transversely extending beams 60 (eg made of wood) is provided. The supports 60d are in turn respectively at their ends and optionally at other points in their course on vertically inserted into a substrate 62d posts 64d (eg., Round logs made of oak wood) superimposed.

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

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

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