Description

The invention relates to a foundation arrangement according to claim 1.

The use of renewable energies, in particular for the production of electricity and / or hot water, by means of solar systems, such as photovoltaic or thermal solar systems, is becoming increasingly important. Such solar systems are used for example in the field or on buildings, eg. B. on flat roofs, set up.

The solar modules (also called solar panels or solar panels) such solar systems are mounted on supporting structures (also known as stand), which are built on suitable foundations. These support structures include, for example, posts and trusses, which allow a direct or indirect support for the solar modules.

To arrange a solar system on a flat roof or on a facade is from the EP 2 256 432 A2 a foundation arrangement with foundation profiles known. The foundation profile has a longitudinal extension and a support flange oriented transversely to the longitudinal extent. The support flange consists of two mutually parallel and spaced-apart sections, each having a support side for supporting the Fundationsprofils on a substrate and one of the support side opposite side. Furthermore, the foundation profile has webs protruding from this side of the subsections of the bearing flange and extending in the longitudinal extent of the foundation profile. The webs are connected in their end region opposite the support flange via a connecting web, wherein this forms a portion of a Hintergreifnut for the arrangement of engaging behind fastening means on the foundation profile. The foundation profile positioned on a surface with the support side is fastened to the substrate.

A disadvantage of this known solution of a foundation arrangement is that in the attachment of the same on a flat roof, the self-tight roof skin of the flat roof is punctually damaged and therefore can penetrate water at these points in the roof structure. In order to continue to ensure the tightness of the roof skin after the preparation of this known foundation arrangement, additional complex structural measures are required.

Furthermore, the known solution of the foundation profile has the disadvantage that for the production of the same a large amount of material is required. With the expected increase in solar systems to be created, there is thus a need for reducing the amount of material required for producing a foundation profile, since the resources available are limited.

From the US 2010/0212720 A1 is to arrange a solar system on a flat roof, a foundation arrangement with several mutually parallel Fundationsprofilen known. Each Fundationsprofil has a longitudinal extent, a transverse to the longitudinal direction aligned support flange having a support side for supporting the Fundationsprofils on the ground and one of the support side opposite side, and projecting from the opposite side of the support flange, extending in the longitudinal extent of the foundation profile web and a in the longitudinal extension of the foundation profile extending Hintergreifnut for the arrangement of rear engagement parts having fastening means on the foundation profile. The Hintergreifnut is provided at the, the support flange opposite end of the web. The foundation profile positioned on a surface with the support side is fastened to the substrate.

A disadvantage of this known solution of a foundation arrangement is that even when mounting the same on a flat roof, the self-tight roof skin of the flat roof is punctually damaged and therefore can penetrate water at these points in the roof structure. Furthermore, the stability of this foundation arrangement is essentially ensured only by the solar panels mounted thereon.

To avoid damage to the roof of a flat roof when creating a foundation arrangement is for example from the US 2010/0154780 A1 known to hang foundation profiles with a C-shaped cross-section only on the flat roof and to complain with weights arranged within the C-shaped cross-section as load material. Due to their design, the foundation profiles according to US 2010/0154780 A1 have a large material requirement for their production.

In order to create a foundation in a subsoil, in particular in the ground, strip foundations are used for a supporting structure, in particular for a solar system (see, for example, US Pat. EP 2 213 961 A2 ) or several individual foundations (see eg US 7,481,211 B2 ), on which the posts of the supporting structure are mounted.

A disadvantage of the known solution of this foundation is that the workload for the creation of such foundations is complex and costly. In addition, just stand out of concrete cast foundations do not always have all the required materials and equipment available at the site of construction.

To solve this problem, z. B. from the DE 20 2008 003 472 U1 So-called pegs or earth screws known as foundation elements, which are driven or screwed into the ground at the site.

A disadvantage of this known solution of a foundation is that depending on the nature of the substrate driving or screwing these foundation elements is only possible to a limited extent and, for example due to lying in the background rocks, usually an undesirable deflection of Erdnägel or earth screws occurs. The elevation or the supporting structure must therefore be provided with appropriate means to compensate for these irregularities in the foundation can. This leads to high construction costs for such a support structure, which in the worst case, the profitability of the solar system in question.

The object of the invention is therefore to provide an advantageous foundation arrangement with a Fundationsprofil, which in particular does not have the aforementioned disadvantages and compared to the known solutions easy to install and has a substantially lower material requirements for its production.

The object with respect to the foundation arrangement is solved by the features of independent claim 1. Advantageous developments are set forth in the figures and in the dependent claims 2 to 6.

According to the invention, the foundation arrangement comprises a foundation profile as a foundation for a supporting structure, in particular for a solar system, wherein the foundation profile has a longitudinal extent, a support flange oriented transversely to the longitudinal extent, which has a support side for supporting the foundation profile on a substrate and a weighting side opposite the support side, and a projecting from the weighting side of the support flange, extending in the longitudinal extent of the foundation profile web and extending in the longitudinal extent of the Fundus profile Hintergreifnut for arranging Hintergreifteilen having fasteners on the Foundation profile, wherein the Hintergreifnut is provided at the, the support flange opposite end of the web , and wherein the foundation profile positioned with the support side on a substrate is weighted with loading material.

It can be easily create a variety of foundation arrangements, which are due to the advantageous properties of the foundation profile, in particular with regard to the resulting total weight, versatile and applicable to different types of buildings. In addition to arrangements on existing buildings, in which the static maximum load capacity plays an essential role, such foundation arrangements are also advantageous for outdoor facilities.

The foundation profile positioned on a surface with the support side is weighted with load material, whereby the entire solar system against lifting off the ground z. B. is secured due to the wind forces acting on the solar system. In particular, any securing measures in which the roof skin is damaged (eg by anchoring or anchoring the foundation profiles on or in the roof structure) are unnecessary with the foundation arrangement according to the invention. As a load material, for example, on a flat roof bulk material, which serves the roofing, or suitable filler used. Alternatively, individual elements, for. As concrete, serve as a burden material, but in contrast to the previously known Fundationsanordnungen no additional measures must be provided. This significantly simplifies the assembly of the inventive foundation arrangement.

Preferably, several, advantageously aligned parallel to each other foundation profiles are provided, which can be easily create over an area expansive solar panels. The distances between the foundation profiles are advantageously matched to the corresponding design of the support structure, so that advantageously no additional auxiliary elements for the arrangement of the corresponding support structure and / or the solar modules are required.

Preferably, side-by-side foundation profiles are connected to one another via at least one transverse profile arranged transversely to their longitudinal extension, with which a stable foundation arrangement can be created. Particularly in the case of large-area installations, the arrangement of at least one transverse profile arranged transversely to the longitudinal extent of the foundation profiles is advantageous for ensuring the stability of the foundation arrangement. Even with foundation arrangements in which z. B. due to the resulting total weight, the foundation profiles are not complained or only with a small amount of loading material, in particular the stability of the foundation arrangement is ensured by the arrangement of at least one transverse profile. In addition, the total weight the foundation arrangement increases, which possibly eliminates the arrangement of loading material for securing the foundation arrangement on the ground. Advantageously, in particular in the case of large-area foundation arrangements, the at least one transverse profile is oriented such that its longitudinal extent runs perpendicular to the longitudinal extent of the foundation profiles. Further advantageously, a plurality of transverse profiles arranged transversely to the longitudinal extent of the foundation profiles are provided.

Advantageously, a frictional connection is provided between the foundation profiles and the at least one transverse profile, so that these profiles are connected to one another and, for example, enable a transmission of forces acting on the foundation arrangement from one of the profiles to an adjacent profile. For example, releasable, z. B. screwed connections or clamp connections provided, which can be easily created during assembly and, if necessary, can be solved again. Alternatively, the profiles z. B. connected by rivets, welding or soldering points. Another, but not final, variant for connecting foundation profiles and / or transverse profiles, are glued joints.

Preferably, the at least one transverse profile has a longitudinal extent, a support flange oriented transversely to the longitudinal extent, which has a support side for supporting the transverse profile on a substrate and a weighting side opposite the support side, and a main web projecting from the weighting side of the support flange and extending in the longitudinal extent of the transverse profile on. The at least one transverse profile thus advantageously has an L-shaped or T-shaped cross section. This embodiment is advantageous in view of the resulting total weight and material requirements of the cross section created and in terms of its stability.

Preferably protrudes from the weighting side of the support flange of the transverse profile at least one parallel to the main web extending side bar, which increases the available surface of the weighting page. Advantageously, a plurality of such side webs are provided on a transverse profile. In particular, when using bulk material as loading material such an embodiment of the transverse profile for securing the entire foundation arrangement of advantage.

Even with the foundation profile, at least one secondary web extending parallel to the main web and projecting from the weighting side of its support flange can be provided, in order to utilize the advantages of the larger, available surface of the weighting page.

With the invention, a deepening trench is first created in the ground, which is advantageous in width only slightly larger than the corresponding largest width extension of the foundation profile to be arranged therein in width. In order to create suitable machines or devices are used for the corresponding substrate (eg soil, rock, concrete, etc.), which are used for example in cable, pipeline or pipeline construction.

Thereafter, at least one foundation profile is arranged in the created trench. Advantageously, a foundation profile is used, as used in the inventive foundation arrangement. Such a foundation profile is arranged in the recess trench so that its Hintergreifnut comes to lie facing away from the bottom of the recess trench.

Subsequently, the recess trench is filled with filling material as a loading material, whereby the at least one foundation profile is securely anchored in the ground.

Preferably, before the arrangement of the at least one foundation profile in the trenches and / or before filling the trenches with filler a the Fundungsprofil at least partially surrounding tissue, knitted fabric or mat material is provided, which on the one hand ensures better anchoring of at least one Fundationsprofils in the filled trenches and on the other hand Protection of at least one Fundationsprofils ensured before material damaging filler. Depending on the nature of the material of the at least one Fundationsprofils and the nature or properties of the filling material can not readily apparent material damage occur on the foundation profile, which significantly reduce its serviceability in the medium or long term. Advantageously, the woven fabric, knitted fabric or mat material has such flexibility that it can easily be arranged at least in regions around the foundation profile. The woven, knitted or mat material includes, for example, geotextiles.

Preferably, a plurality of groove trenches, preferably running parallel to each other, for the purpose of accommodating a plurality of foundation profiles are created, in each of which at least one foundation profile is arranged. This process step is advantageous in areally designed solar systems. Advantageously, the distances between the recessed trenches are matched to the corresponding configuration of the support structure, so that advantageously no additional auxiliary elements for the arrangement of the corresponding support structure and / or the solar modules are required.

Preferably, the material used in the creation of the trenches ditch is used as filler, whereby the logistical effort for the creation of the foundation and thus the entire support structure is reduced. If the material produced during the creation of the depression trench is insufficient for adequate filling or anchoring of the foundation, this can be supplemented or replaced by further filling material which may have better material properties.

Preference is advantageously determined prior to the creation of the trenches whose depth to be created depending on the weight of the filling material used and the required to secure the support structure retaining force. This ensures easy creation and sufficient security of the foundation. When creating the trench, only enough material is removed from the substrate, as required to ensure a sufficiently strong foundation. Advantageously, the planner and / or the implementer are provided with appropriate aids (eg tables or computer programs) by means of which he can calculate or read off the required depth in advance.

In the 1 is a foundation arrangement according to the invention 11 on a subsoil, here a flat roof, using foundation profiles 21 shown, which as a foundation for a supporting structure 12 a solar system 16 serves. The solar system 16 includes several rows of juxtaposed solar modules 17 which, for example, in a frame construction 18 are arranged.

The supporting structure 12 includes posts in this example 13 and traverses 14 , which have suitable connecting elements 15 at the foundation profiles 21 are fixed. On this support structure 12 becomes the frame construction 18 directly or indirectly supported by intermediate elements.

The foundation arrangement 11 is of several, here parallel aligned Fundationsprofilen 21 and a plurality of transverse profiles arranged parallel to one another and arranged transverse to their longitudinal extent 36 formed the foundation profiles 21 connect with each other. Between the foundation profiles 21 and the cross sections 36 For example, a frictional connection is provided.

Reaches the total weight of the solar system 16 to secure them on the ground to take over the solar system 16 The burdensome profiles do not turn out to be burdensome 21 and thus also the cross profiles 36 with a, here represented by points, load material, z. B. a bulk material 19 , which advantageously serves the roofing, complains. This process is with the filling of the trench 62 in the in the 5 to 7 comparable procedures described. At least the foundation profiles 21 the foundation arrangement 11 are at least partially covered with loading material. The bulk material 19 or the load material can extensively or intensively planted green or with a floor covering, z. As from paving stones or garden plates, are occupied.

2 shows the foundation profile 21 in an enlarged view, which is made in this example of aluminum, advantageously made of an aluminum alloy. These materials are particularly related to the resulting total weight of the foundation profile 21 and its capacity is preferred. Furthermore, in simple methods, such as in a Extrusion process, the foundation profile 21 be made. Alternatively, suitable plastics or composites are used which can be brought into the desired shape and are suitable for taking over the forces that occur. Unless the weight of the foundation profile 21 is of secondary importance, the foundation profile, for example, from other materials, such. B. made of steel.

The foundation profile 21 has a longitudinal extent, a transverse to the longitudinal direction aligned support flange 22 who has a support page 23 for the circulation of the foundation profile 21 on a surface and one of the bearing side 23 opposite ballot page 24 and one from the weighting page 24 of the support flange 22 protruding, in the longitudinal extension of the foundation profile 21 running bridge 26 on. The jetty 26 protrudes between the two in the longitudinal extension of the foundation profile 21 running lateral edges 25 of the support flange 22 from its weighting page 24 from. The foundation profile 21 thus has a T-shaped cross section, which allows a stable arrangement of the foundation profile on a substrate.

At the, the support flange 22 opposite end of the bridge 26 is one in the longitudinal extension of the foundation profile 21 extending Hintergreifnut 28 for the arrangement of rear grip parts 72 having fasteners 71 at the foundation profile 21 intended. In contrast to conventional steel profiles with a comparable cross-section, the foundation profile 21 a simple attachment for suitable fasteners, such as rail nuts on. Therefore, for example, no on-site welding is required, which requires several expensive measures for a sufficient quality of the connection created.

The Hintergreifnut 28 points in the longitudinal extension of the foundation profile 21 extending, spaced edges 29 , which has an insertion longitudinal slot 30 for rear grip parts 72 define. The over the Einführlängsschlitz 30 accessible space 31 has a width E which is greater than the corresponding distance A of the edges 29 to each other, leaving one in the room 31 introduced and twisted in this and appropriately trained rear grip 72 the free ends of the edges 29 can engage.

On the same level as the Hintergreifnut 28 are each on both sides of the same projecting further, in the longitudinal extension of the Fundationsprofils 21 extending, the support flange 22 opposite and spaced apart flanges 32 intended. The in this area transverse to the longitudinal extent of the foundation profile 21 measured width C, which is the distance of the free edges 33 the flanges 32 corresponds to each other, is smaller than that transverse to the longitudinal extent of the foundation profile 21 measured width B of the support flange 22 , In this embodiment, this width C is 50% of the mass of the width B of the support flange 22 , The second flanges 32 serve the user for example as an installation aid and give z. B. the maximum Schütthöhe a ballast material to complain the Fundationsanordnung 11 at. By such a configuration, the foundation profile can be 21 with high load capacity in relation to the required material requirements for the production of the foundation profile 21 optimize.

The flanges 32 represent a stiffening of the foundation profile 21 and thus an improved load transfer safely. In addition, these flanges 32 serve as installation aid for a user. Because the flanges 32 on the same level as the Hintergreifnut 28 at the end of the jetty 26 are arranged, is an enlarged contact surface for a on the Fundungsprofil 21 arranged attachment available, such as a post 13 the supporting structure 12 or a corresponding connecting element 15 , As a result, higher loads can be transmitted via the connection and the material required for the production of such a foundation profile 21 is still relatively lower than in the previously known profiles.

The jetty 26 has a middle section 33 with less material thickness than at its end regions. The extension of the middle section 33 is essentially of the static requirements on the foundation profile 21 dependent, with the transitions to the end portions of the web 26 advantageously run continuously with the greater material thickness.

The support flange 22 is in this example with two, respectively to the edges 25 of the support flange 22 and in the direction of the longitudinal extent of the foundation profile 21 ongoing weakenings 34 provided, which is a simple reduction of the width B of the support flange 22 enable. Advantageously, this adjustment at the installation site directly by the user and further advantageous vornehmbar without a special additional tool.

In an alternative embodiment, not shown here, a foundation profile is used for the foundation arrangement or at least for a part thereof, which has, for example, an L-shaped cross-section and therefore a much lower material requirement compared to the known foundation profiles. Even with an L-shaped foundation profile, the Hintergreifnut advantageously arranged directly at the free end of the web. As a result, viable profiles can be created with respect to the known profiles smaller dimensions.

Dashed is in the 2 an upper edge of a weighting with bulk material 19 as weighting material shown schematically.

3 shows the cross profile 36 in an enlarged view, which is also made of aluminum in this example. Also for the cross profile 36 can use the same or similar materials as for the foundation profile 21 be used.

The cross profile 36 has a longitudinal extent, a transverse to the longitudinal direction aligned support flange 37 who a pad side 38 for supporting the cross profile 36 on a surface and one of the bearing side 38 opposite ballot page 39 and one from the weighting page 39 of the support flange 37 protruding, in the longitudinal extent of the transverse profile 36 running main bridge 46 on.

From the weighting page 39 of the support flange 37 of the cross section 36 protrude on both sides of the main bridge 46 parallel to this running outer side bars 41 and inner sidewalks 42 from. The outer side walkways 41 are each at the lateral edges 40 of the support flange 37 intended. The other, inner side walkways 42 are each between the outer side bars 41 and the main pier 46 provided as well as each spaced therefrom.

In each case between the outer side walkway 41 and the inner side walkway 42 is the support flange 37 on his page 39 with a weakening 43 Mistake. Also the main bridge 46 has on both sides in each case one in the direction of the longitudinal extension of the transverse profile 36 extending and to the free, the support flange 37 opposite end 47 a weakening 48 on. The weakenings 43 and or 48 allow a user in a simple way the cross profile 36 if necessary, to adapt to local conditions.

Apart from the flange additionally spaced apart from the support flange, the foundation profile has 51 according to 4 essentially the same or at least similar features to those in the 2 Funding profile shown 21 on.

Also the foundation profile 51 thus has a longitudinal extent, a transverse to the longitudinal direction aligned support flange 52 who has a support page 53 for the circulation of the foundation profile 51 on a surface and one of the bearing side 53 opposite ballot page 54 and one from the weighting page 54 of the support flange 52 protruding, in the longitudinal extension of the foundation profile 51 running bridge 56 on.

At the, the support flange 52 opposite end of the bridge 56 is one in the longitudinal extension of the foundation profile 51 extending Hintergreifnut 58 for the arrangement of rear grip parts 72 having fasteners 71 at the foundation profile 51 intended. The Hintergreifnut 58 corresponds in the embodiment of the Hintergreifnut 28 of the foundation profile 21 ,

Advantageously, all of the provided with a Hintergreifnut profiles that for the creation of the foundation arrangement 11 used, and more advantageously, the entire support structure similarly or identically configured Hintergreifnuten, so that in the corresponding construction with only one type of fasteners 71 has to be worked. This prevents the placement of incorrect, unsuitable fasteners, which can lead to failure of the created connection, and significantly simplifies the logistical effort.

It goes without saying that instead of foundation profiles 21 or 51 and cross sections 36 also only foundation profiles 21 and or 51 can be used to create a foundation arrangement. Next is instead of using cross profiles 36 To stabilize or increase the overall weight of the foundation arrangement, the use of conventional profiles already on the market is conceivable, although this is preferred.

The illustrated foundation profiles 21 or 51 as well as the cross profile 36 each have an axisymmetric cross section. However, this embodiment is preferably not mandatory. Depending on the local conditions, the use of asymmetric cross sections for creating a foundation arrangement may also be advantageous.

In the 5 to 7 is a method of creating a foundation 61 in a subsoil, here in the ground, for a supporting structure, here for a solar system, shown.

First, a trench ditch 62 in the underground 63 created with a suitable device (see 5 ). This when creating the trench 62 accumulating material is, with appropriate suitability as a filler 64 or weighting material, the side of the recess trench 62 landfilled. The width F of the trench 62 is advantageously chosen such that it is slightly larger than the width B of the support flange 22 of the foundation profile to be arranged 21 is. The depth T of the trench 62 is determined as a function of the net weight of the filling material used and the retention force required to secure the supporting structure. The user is advantageously an aid, such as a table or a computer program available, so that the required depth T for each application is easily determined by the user.

In the created trench 62 becomes a foundation profile 21 , on which in some areas a geotextile 66 was provided as a fabric arranged (see 6 ). The fabric, which may alternatively be a knitted fabric or mat material, surrounds this in the recessed trench 62 arranged foundation profile 62 advantageous such areas, that its free ends of the recess trench 62 protrude.

The foundation profile shown here 21 has an advantageous for the arrangement of a supporting structure of a solar system configuration. However, other foundation profiles may be used which are suitable for an arrangement of a support structure and at least have a support flange projecting laterally with respect to the web.

Subsequently, the space between the geotextile 66 protected foundation profile 21 and the boundary edges of the trench 62 remaining space with filler 64 filled up (see 7 ). Unless the suitability of the filler 64 as weighting material and / or as anchoring material for the foundation profile 21 in the underground 63 is given, this is advantageously used. Otherwise, suitable filling material will be suitable for this purpose 64 fed.

That now safely in the underground 63 anchored foundation profile 21 forms the foundation, for example, for a supporting structure 12 as they are in the 1 is shown. The inventive method was with a Fundationsprofil 21 described what is preferred due to the achievable anchoring values and resulting retention forces. However, it is also conceivable already known profiles, such as in the EP 2 256 432 A2 profile shown to use as a foundation profile in this inventive method.

At the foundation profile 21 is a suitably trained connecting element 15 provided, which z. B. the arrangement of the post 13 serves. For fixing the connecting element 15 at the foundation profile 21 is a fastener 71 provided, which is a rear grip part 72 and a cooperating with this clamping screw 73 includes.

The fastener 71 , z. B. a rail nut is in the 7 shown in the clamped state. The rear grip part 72 However, in a perpendicular to the in the 7 Plane extending direction advantageously a dimension which is smaller than the corresponding width C of the Einführlängsschlitzes 30 the Hintergreifnut 28 of the foundation profile 21 is. Thus, the rear grip part 72 at any point along the longitudinal extent of the foundation profile 21 in the Hintergreifnut 28 be introduced. The in the 7 illustrated dimension of the rear grip part 72 is greater than the corresponding width C of Einführlängsschlitzes 30 the Hintergreifnut 28 of the foundation profile 21 , so that after twisting in the Hintergreifnut 28 inserted rear grip part 72 to a certain, essentially of the design of the rear grip part 72 dependent angular amount, here by about 90 °, the free edges 33 the Hintergreifnut 28 when tightening the fastener 71 by means of the clamping screw 73 be underrun.

At least two and for planar solar systems also several, preferably parallel to each other deepening trenches 62 for holding several foundation profiles 21 created, in each of which at least one foundation profile 21 is arranged.

The individual details described in connection with the figures can of course also be provided in the other embodiments.
