Description

The The invention relates to a mounting system for stands for photovoltaic open-space plants and a stator made of the mounting system and its stationary arrangement. Stands constructed from such mounting systems provide the upper components of photovoltaic systems on open ground linear supports in a fixed adjustable and solar energy cheap Tilt.

For such stand Mounting systems are already known to the person skilled in the art. They include in Essentially each one to be founded in the ground support, a sloping beam as linear Support, an additional Strut for striving the inclined beam against the support and three joints. By means of the joints, the support, the oblique bar and the strut to a fixed adjustable stand in the form of a triangular truss be assembled. Here, the two joints include to the sloping beam respectively a separate joint approach. These two joint approaches are on the ends of the strut and the support rigidly placed, and they can by means of bolts on the sloping beam along a longitudinal guide different positions and in different angular positions be clamped. Longitudinal guide, pivot bearing and clamping done systemic with the same bolt. The assembly of components of such a system decreases including Stellstellungen for a correct inclination and position of the inclined beam a few handles and time and also requires conscientious work.

It is therefore an object of the invention, the installer a mounting system of to give the above-mentioned way, which is easier and faster than previously built.

The The object is achieved with the mounting system for stands for photovoltaic open-space systems specified in claim 1 solved. Accordingly, one stand per stand support and a slanted beam and a strut for striving the inclined beam against the support provided, the support, the sloping beam and the strut to a fixed adjustable stand in the form of a triangular truss can be assembled and for this between sloping beams and prop a first and between slanted beams and strut a second and between strut and prop one third articulated connection is provided and the first articulated connection a first hinge extension and the second hinge connection a second Includes joint approach and the two joint approaches on the inclined beam are longitudinally arranged can be arranged.

The An innovation is that one comprising the diagonal beam and the two joint approaches Assembled assembly, wherein the two joint approaches on the sloping beam non-rotatably longitudinally guided and there are fixed to target positions, and that the support with the first joint approach and the strut with the second joint approach are pivotally connected.

in this connection is the prop of the mounting system according to the invention destined to be fixed in place at the site of the open space plant to be, especially in the ground or on a foundation, and loads to be removed downwards. A vertical foundation by ramming has become thereby particularly well proven in practice. It is also conceivable to erect the support at an angle.

Of the oblique bar is as a linear Support for provided the upper components of the open space plant. at erected stand is the oblique beam ideally to the south aligned and running in a solar-energetically favorable, firmly set inclination. On the sloping beam can in particular transverse Module support profiles are mounted, on which in turn the photovoltaic modules the open space facility are installable.

at erected stand is the oblique beam on a statically favorable Position between its ends preferably directly above the support arranged, and the strut can obliquely down the sloping beam against the support abstreben. In this way, a framework can be generated, which in its shape includes the basic shape of a triangle. These Triangular geometry is based, as known from the prior art, expediently on the result of a static calculation, preferably by a Structural engineer performed and in particular the desired inclination, length and Load of the inclined beam considered. The positions of the first and second joints along the oblique bar and the position of the third hinge joint along the support can be determined according to such a static calculation given and accordingly be target positions.

In contrast to the known mounting system are the main functions of the two joint approaches, on the one hand a pivot bearing and on the other hand to provide an approach to be reversed. According to the invention, therefore, the joint approaches can be attached to the inclined beam and instead the support and the strut are arranged pivotally relative to the joint approaches. In addition, the joint approaches on the inclined beam are longitudinally slidably guided, whereby a displacement of the joint approaches along the inclined beam continues to be possible, a pivoting relative to the But slanted beam is prevented. Finally, it is particularly important that the articulation lugs are prefabricated on the sloping beam and therefore form an assembly together with the inclined beam. It is crucial that the joint approaches along the inclined beam are already firmly attached to their predetermined target positions, ie at the positions where the joint approaches are provided in accordance with plan erected stand according to the aforementioned statics calculation.

Of the The main advantage of the invention results from the prefabricated assembly. In the known from the prior art mounting system would be a Pre-assembly theoretically conceivable, because of the above-mentioned triple function the bolt but not practical, since the joint approaches not only at their desired position, but at the same time in their exact angular positions be clamped. The fact that the functions pivot bearing and piecing spatially changed according to the invention are provided the joint approaches on the sloping beam be non-rotatably longitudinally guided. As a result, it is now possible the joint approaches in a simple manner at the respective predetermined location on the sloping beam independent of firmly fix the pivot bearing, preferably already factory and in series.

The prefabricated assembly saves the fitter on site some essential Handles during the erection of the stand. This is not just work for the Assembly of the joint approaches, but in particular the adjustment of the inclination of the inclined beam and its positioning over the prop completely eliminated, which in the prior art because of the triple function the bolt is indispensable part of the building. From the same Reason is it for the fitter easier than before, especially at a faulty set prop, adjust the inclination and the position of the inclined beam. So can the both joint approaches on the sloping beam respectively detached from their nominal position, moved and at one more appropriate correction position are fixed again, without that rigid angles squeeze the triangle framework, since the three joints while and can remain free from rotation even after assembly. In summary, it can be note that the mounting system according to the invention also by a less experienced fitter erected in a significantly shorter time than before to a stand can be. The mounting system is therefore particularly suitable for photovoltaic ground-mounted systems on an industrial scale.

In a first preferred embodiment At least one of the two joint approaches to a joint portion Bearing a hinge pin, wherein the hinge portion arranged so is that the axis of rotation of a hinge pin mounted there the oblique bar outside crosses. Preferably, the hinge pin can be stored so that with erected stand its axis of rotation the oblique beam crosses below. This can make the design of the joint approaches clear simplify. With sufficient distance between the sloping beam and the rotation axis may also have access to release, move and lock the joint approaches along the oblique bar be kept free of swiveling components. Therefore, the Joint approach along of the slanted beam too correspondingly short executable without, for example, being crossed by the strut crossing. For storage of the hinge pin can be provided in particular in the joint section axle holes, so that a pivot bearing is easy and reliable to produce. Thereby, that the rotation axis outside runs, can use a single and correspondingly long hinge pin be without losing the slanted beam to penetrate. After all the second hinge extension is preferably designed so that a strut mounted there can be folded in towards the sloping beam.

In In a further development, the joint section is at least one Joint approach executed U-shaped profile. One such joint section extends in particular parallel to the sloping beam and is at erected stand open at the bottom. He can act in the manner of a fork with two opposite cheeks, which is the end of the prop or the strut or possibly attached thereto rod ends by means can absorb a hinge pin articulated. In addition, U-shaped joint approaches essentially by cutting to length an extruded profile strand simple and inexpensive in Produce series.

In a further preferred embodiment the joint section has at least one joint attachment for storage a hinge pin open axle slots. A hinge pin can in the preferably two open axial slots easier than in axial bores are used, since when erecting the joint parts to be joined no longer need to be brought exactly to coincide axially. Besides that is it is possible in a particularly advantageous manner, the hinge pin the counterpart of the Pre-mount the articulated connection.

In addition, it may be appropriate to make the open axial slots of the joint portion of the first joint approach so that they are open at erect stand down. As a result, the first articulated connection can be produced by merely placing the inclined beam at least in preparation. For this purpose, the inclined beam at its first joint approach needs to be set only on a hinge pin, which on the support or an optionally attached thereto joint head is already mounted mounted. The open axial slots are preferably oriented approximately vertically downwards when the stand is erected. However, a deviation of several degrees is well tolerated, so that such a joint approach for inclined beams in different inclinations is suitable. In particular, it is expedient to provide the axial slots approximately at an angle of 60 ° to the inclined beam.

In In a further development, the joint section comprises at least one Joint approach a safeguard against radial release of a hinge pin the open axle slots. This can in particular be a replacement of the oblique bar Reliably prevent lifting wind loads.

Prefers is provided to secure against radial loosening a gate valve, the tangential to a hinge pin in the hinge section inserted is. Such a locking slide can be designed in particular as a plate, in inner longitudinal guides a U-shaped profile Joint portion below the hinge pin, d. H. on the oblique bar opposite Side of the hinge pin, is inserted.

In a further preferred embodiment indicates the diagonal beam for longitudinal guidance of the two joint approaches at least one longitudinal groove, the undercut is. Related to a built up stand preferably in the left and right outside of the inclined beam each an undercut longitudinal groove integrated. Using a longitudinal groove can the joint approaches easy and safe along of the sloping beam be moved and determined. In particular, this can be a multiple proven Combination of sliding block and screw can be used. To the Joint approaches on oblique bar According to the invention can be longitudinally non-rotatably, can alternatively or in addition one with the longitudinal groove parallel running guide rail be provided on the joint approach. However, it is preferably possible, depending Joint attachment at least two combinations of sliding block and screw in the same longitudinal groove spaced apart to provide in this way a twisting to prevent.

In a further preferred embodiment has at least one of the two joint approaches a U-shaped profile neck portion on, on which the joint projection attached to the inclined beam non-rotatably longitudinally is. Similar like the joint portion, the neck portion may also be U-shaped. Preferably, in this case, the inner contour of the neck portion corresponds with the outer contour of the sloping beam, so that the Ansetzabschnitt the inclined beam in the manner of a sliding carriage embraces. Such an approach section can in particular to the previously mentioned longitudinal grooves be clamped.

In a further preferred embodiment At least one of the two joint approaches H-profile designed, wherein the shape of the joint approach of the above-described U-shaped joint section and the U-shaped profile Neck section results. This allows the inner contour of the joint approach at its upper portion with the oblique beam and at its lower Section with the strut or the support or the attached if necessary Joint partners correspond. In addition, such a joint approach easy and inexpensive essentially by cutting to length a correspondingly extruded profile strand are produced.

In a particularly preferred embodiment For example, the first articulated connection comprises a condyle which is attached to the upper end of the prop put on and over a hinge pin hingedly connected to the first hinge extension can be. The top of the column may only be suitable Conditionally as a joint partner, since it when building, especially during Construction by means of ramming, can be easily damaged. Here offers a separate condyle, preferably after erection the prop on top of this, special benefits. Corresponding is the support with the first joint approach by means of this intermediate joint head pivotally connectable. In a further development, the condyle can transverse to the support and / or parallel to the support slidably mounted. This can cause deviations from the vertical and deviations from a desired height, which often arise in practice when erecting the support, corrected become. Here is a transverse and height adjustment of about + -15 mm is most of the time sufficient.

In Another optimization, the joint head a hinge pin height adjustable take up. The condyle can do this in the manner of a fork two cheeks in which axial slots are included, which when built stand run approximately vertically. The hinge pin can then on the cheeks at different heights be tightened. It can for securing against slipping on screw nuts provided for the hinge pin and integrated on the cheeks meshing serrations be. additional Is it possible, to provide the axial slots open at the top.

In a further preferred embodiment, an additional rotational degree of freedom is provided for compensating for a rotation of an erected support in the first and the third articulated connection. This allows the inclined beam together with the strut despite a Umstän under circumstances the twisted erected in its longitudinal axis support be placed in the intended azimuthal orientation. The compensation of a rotation is particularly important if the support is to be arranged in a row of columns. Here, a twist range of about + -10 ° has been found to be sufficient. The additional rotation axes are preferably aligned vertically or parallel to the support. But it is also possible to provide the additional rotation axes to a limited extent kinking. It is essential that the inclined beam can be rotated together with the strut about the longitudinal axis of the support.

In a further development in combination with the previously described Condyle can this around the prop and / or vertically rotatably mounted on the upper end of the support become.

And in a further development in connection with the third articulation this includes a joint part with two mutually perpendicular axes of rotation, with the hinge part on the support and can be arranged at the lower end of the strut. Such a hinge part may preferably be designed in the manner of a universal joint, however, it is not necessary that their axes of rotation intersect. For easy connection to the prop can there at a given height Axle holes for a hinge pin may be provided which cooperate with the hinge part can.

In a further embodiment are for the third joint longitudinally the prop at different heights several axle bores for provided a hinge pin. This can be both for a simple Tilting joint as well for the joint part described above be advantageous since in this way a standard support flexible for different slopes of the sloping beam and for different strut lengths may be suitable.

In a particularly preferred embodiment comprises the assembly according to the invention also the strut, wherein the strut pivotally connected to the second joint approach is. This saves the fitter further on-site which can be done more efficiently at the factory in series. The The strut can be directly or via a strut-side joint partner be pivotally connected to the second joint approach. For this Connection may be suitable in particular a hinge pin. In a Further development, the strut is folded in to the sloping beam. Thereby can the pack size of Assembly be kept small. Preferably, the strut is included against unintentional folding away, especially during a Loading, secured.

In a further preferred embodiment the assembly according to the invention comprises several Retaining elements for to the sloping beam transversely to be arranged support profiles, wherein the holding elements to target positions or nearby of these at the slanted beam are arranged. These holding elements can preferably be shaped in such a way that the support profiles first Tool-free, especially by mere insertion or hooking on the sloping beam at least provisionally be fastened. In an advantageous way can so further time-consuming assembly steps on site accounts for the factory more efficient and even automated.

following is an embodiment of the assembly system according to the invention closer by means of drawings explained. Show it:

To overview shows 1 the substructure of a photovoltaic open-space plant with three erected from the mounting system according to the invention stands. Each stand includes a support 1 , a sloping beam 2 as well as a strut 3 , which are composed of three joints to a triangular framework. The three articulated joints will be explained in detail below.

Out 1 It is also evident that the supports 1 stand vertically and with their lower sections in the ground 4 are founded and evenly spaced form a straight column row. The sloping beams are at an angle of about 30 ° to the row of columns 2 on the supports 1 attached. For striving the oblique beams 2 against the supports 1 are also the pursuits 3 at her lower ends with the supports 1 and at their upper ends with the slanted beams 2 articulated. Further, on the sloping beams 2 six module support profiles parallel to the column row 5 evenly spaced mounted. And on the module support profiles 5 Finally, photovoltaic modules not shown in detail can be installed.

In 2 is one of the stands according to 1 with its three joints 20 . 70 and 90 shown in more detail, wherein the first hinge connection 20 between the sloping beam 2 and the prop 1 , the second articulation 70 between the sloping beam 2 and the strut 3 and the third articulation 90 between the strut 3 and the prop 1 consists. The three joints 20 . 70 and 90 each have an imaginary tilt axis 21 . 71 respectively. 91 which runs approximately horizontally and ideally parallel to the column row.

Because the three distances between the joints 20 . 70 and 90 or between their tilt axes 21 . 71 and 91 are fixed, that is from the prop 1 , the sloping beam 2 and the strut 3 enclosed triangle defined geometrically in its interior angles. It is therefore not necessary torques on the tilt axes 21 . 71 or 91 take.

The main geometry of the stator is based on the result of a static calculation, which can preferably be performed by a structural engineer and in particular the desired inclination, length and load of the inclined beam 2 considered. The positions of the first and second articulations 20 and 70 along the sloping beam 2 and the position of the third articulation 90 along the support 1 are specified according to this static calculation and thus target positions. For a fitter, these target positions can be conveniently removed locally from a structural plan based on the static calculation.

In 3 and 4 First is the simpler second hinge connection 70 of the stand according to 2 shown in detail. Main element of the second hinge connection 70 is a joint approach 72 whose front side is in 4 highlighted by dot hatching. The joint approach 72 is essentially a symmetrical extrusion and consists in the upper part of a Ansetzabschnitt 73 and at the bottom of a joint section 74 , Both the Ansetzabschnitt 73 as well as the joint section 74 are designed approximately U-shaped profile, wherein the Ansetzabschnitt 73 upwards and the joint section 74 is opened downwards and the Ansetzabschnitt 73 two spaced cheeks 76 and the joint section 74 two spaced cheeks 77 and the two sections 73 and 74 through a common middlebridge 75 are split, so for the joint approach 72 a profile with approximately double U-shaped or H-shaped cross-section is given.

Besides, it is off 4 the special cross section of the inclined beam 2 seen. The sloping beam 2 is a hollow extruded profile with a rectangular basic shape, whose corner areas and underside are strongly rounded. In the top of the sloping beam 2 is an undercut longitudinal groove 10 integrated, which attach to the in 1 illustrated module support profiles 5 is provided. In addition, in the left and in the right outside of the inclined beam 2 in each case a further undercut longitudinal groove 11 integrated, both for attachment of the joint approach 72 be used. To mention remains that on both sides of the opening slots of the longitudinal grooves 11 recognizable and in the views to scale scale as black stripes shown corrugations are of minor importance here.

3 and 4 further show that the joint approach 72 on the sloping beam 2 According to the invention non-rotatably longitudinally guided is attached. This is the joint approach 72 on both sides via two screw connections on the undercut longitudinal grooves 11 of the sloping beam 2 slidably clamped. The four screw connections each comprise a screw bolt 78 as well as a square nut 79 which serves as a groove stone. The bolts 78 lead through four corresponding holes in the two cheeks 76 the Ansetzabschnittes 73 in the undercut grooves 11 where they are using the square nuts 79 axially against the undercuts of the longitudinal grooves 11 are tense. Because to the left and right outside of the inclined beam 2 there are two screw connections and these along the longitudinal grooves 11 can be spaced, the joint approach 72 on the sloping beam 2 not be twisted. In addition, the inner contour of the Ansetzabschnittes corresponds 72 over a wide range with the outer contour of the inclined beam 2 so that the joint approach 72 in the manner of a shoe along the sloping beam 2 slidably guided. If the four screw connections are released, the joint approach 72 along the sloping beam 2 or in one of the directions of the double arrow 80 moved out of its nominal position and on the sloping beam 2 be fixed again at another position or a correction position.

In addition, in 3 and 4 revealed as the strut 3 over a hinge pin 81 at the joint approach 74 in the directions of the double arrow 83 is mounted pivotably. So cover the cheeks 77 of the joint section 74 the upper end of the strut 3 in the manner of a yoke, wherein the hinge pin 81 by two axis drilling in the cheeks 77 and by two axle holes in the upper end of the strut 3 leads and with a mother 82 is axially secured. The hinge pin 81 runs in the tilt axis 71 corresponding to below the inclined beam 2 , In addition, the connection between the strut 3 , which has a square hollow cross-section, and the joint approach 72 designed so that the strut 3 to the sloping beam 2 can be folded down. This is between the upper end of the strut 3 and the central pier 75 of the joint approach 72 given sufficient freedom of movement.

5 and 6 show the first articulation 90 of the stand according to 2 in detail. Main element of the third articulation 90 is a joint body 92 who is the strut 3 with the prop 1 on the tilt axis 91 and a rotation axis perpendicular thereto 93 articulates in two rotational degrees of freedom and acts like a universal joint, but whose axes do not intersect at one point.

In particular, from the exploded view according to 6 it can be seen that the joint body 92 as U-shaped extrusion with two opposite cheeks 94 and a central pier 95 executed and a first hinge pin 96 between two side walls of the column 1 around the tilt axis 91 is pivotally mounted. This is in the middle of the central pier 95 a cylindrical bolt receptacle 97 integrated, parallel to the tilt axis 91 runs. The first hinge pin 96 leads through this bolt receptacle 97 as well as left and right by two unspecified axial bores in the side walls of the support 1 , which is designed as U-shaped or slightly trapezoidal rolled profile, so that the support 1 the joint body 92 Tilting in the manner of a yoke and receives the strut 3 so that it is movable in its inclination. The axial bores in the side walls along the column 1 are preferably already provided at the factory. And their position results expediently from the statics calculation mentioned above.

Furthermore, the strut 3 via a second hinge pin 98 around the axis of rotation 93 pivotally connected. These include the two cheeks 94 the lower end of the strut 3 on the upper and lower side, and it's in both cheeks 94 as well as in the upper and lower side of the end of the strut 3 each except two axle holes through which the second hinge pin 98 leads. In this way, the joint body decreases 92 the strut 3 between his cheeks 94 also pivoted in the manner of a fork, so that the strut 3 in case of a possible rotation of the support 1 from the column row is correctly aligned.

7 shows the first joint 20 of the stand according to 2 in detail. The first joint 20 essentially comprises one on the support 1 fortified platform 22 , one on the platform 22 slidably arranged clevis 23 with a hinge axis 24 and one over the hinge axis 24 tiltably mounted joint approach 25 , in turn, at the sloping beam 2 is slidably attached. For further clarification, in 8th to 10 the main elements of the first articulation 20 shown separately.

The platform 22 is an extruded part with a T-shaped cross-section, which has a wide central web with cavities. In addition, the platform has 22 over a flat top 26 for the clevis 23 at the head of the support 1 provides a horizontal support. The attachment of the platform 22 on the prop 1 done by means of two screw connections 27 through corresponding holes in the side walls of the column 1 and in the middle bridge of the platform 22 to lead.

The clevis 23 is also made of an extrusion. He has a foot 28 with a flat bottom 29 which act as a sliding partner to the top 26 the platform 22 acts. The clevis 23 can therefore be on the platform 22 being moved and twisted, being for attachment and guidance in the platform 22 two unspecified and across the sloping beam 2 aligned slots are excluded and in the left and right sides of the foot 28 two more slots 30 are excluded, which are parallel to the sloping beam 2 run. The long holes 30 in the foot 28 as well as the slots in the platform 22 are therefore arranged so that they each form a crossing pair of holes, each pair of holes a screw 31 consists. In this way, the clevis can 23 on the platform 22 opposite the support 1 moved transversely and also longitudinally to the column row by a small amount and then found. Since between the hole walls of the two pairs of holes on the one hand and the shafts of the screw 31 On the other hand, there is some movement, the clevis can 23 also slightly opposite the platform 22 around a vertical axis of rotation 62 be twisted to allow the slanted beam 2 in case of a possible rotation of the support 1 from the row of columns can be aligned azimuthally correctly. This correction can be done along with the strut 3 be done, since this according to 5 and 6 also in two rotatory degrees of freedom at the support 1 is hinged. That the rotation axis 93 of the joint body 92 according to 5 not with the axis of rotation 62 Aligns can be tolerated in the usually small correction angles.

Furthermore, it can be seen that perpendicular to the foot 28 of the clevis 23 two parallel spaced fork cheeks 35 are arranged in each of which a vertical axis slot 36 for the hinge axis 24 is excluded for height-adjustable storage. As in particular from 9 can be seen comprises the hinge axis 24 one through both axial slots 36 leading bolt 37 , A mother 38 and a cylindrical spacer sleeve 39 between the two fork cheeks 35 and coaxial on the bolt 37 is arranged. It is also between the outsides 40 the fork cheeks 35 and the head of the bolt 37 or the mother 38 one square washer each 41 coaxially interposed. It is essential that the hinge axis 24 in the axial slots 36 or in one of the directions of the arrow 61 is height adjustable. This may be the bolt 37 dissolved, moved down or up and tightened at a different height again, with the spacer sleeve 39 When bracing prevents the fork cheeks 35 be claimed on bending. So that the hinge axis 24 not accidentally slipped down or up, are both on the outside 40 the fork cheeks 35 as well as on the insides of the square washers 41 not shown in the drawings, horizontally extending serrations incorporated when tightening the hinge axis 24 mesh. In this way, the hinge axis 24 almost infinitely on the fork cheeks 35 along the axial slots 36 height adjustable and also secured against slipping. The serrations can preferably be manufactured by extrusion.

Out 7 to 10 It can also be seen that the joint approach 25 very similar to the joint approach 72 the second joint according to 3 and 4 is constructed. This is the joint approach 25 also essentially a symmetrical extruded part and consists in the upper part of a Ansetzabschnitt 53 and at the bottom of a joint section 54 , Likewise, the Ansetzabschnitt 53 and the joint section 54 approximately U-shaped profile, wherein the Ansetzabschnitt 53 upwards and the joint section 54 is opened downwards and the Ansetzabschnitt 53 two spaced cheeks 56 and the joint section 54 two spaced cheeks 57 and the two sections 53 and 54 through a common middlebridge 55 are divided, so that a profile is given with approximately double U-shaped or approximately H-shaped cross-section.

Also, the joint approach 25 in the same way according to the invention on the sloping beam 2 unrotatable longitudinally guided. This is the joint approach 25 again on both sides via two screw connections on the undercut longitudinal grooves 11 of the sloping beam 2 slidably clamped. The four screw connections each comprise a screw bolt 58 and a square nut, which is used as a sliding block. The bolts 58 lead through four corresponding holes 59 in the two cheeks 56 the Ansetzabschnittes 53 in the undercut grooves 11 , where they by means of the square nuts axially against the undercuts of the longitudinal grooves 11 are tense. As with the joint approach 72 according to 3 and 4 to the left and right outside of the inclined beam 2 there are two screw connections and these along the longitudinal grooves 11 can also be the joint approach 25 on the sloping beam 2 not be twisted. Likewise, the inner contour of the Ansetzabschnittes corresponds 53 over a wide range with the outer contour of the inclined beam 2 so that the joint approach 25 in the manner of a shoe along the sloping beam 2 slidably guided. If the four screw connections are released, the inclined beam can 2 in one of the directions of the double arrow 60 opposite the joint approach 25 moved and fixed again.

In addition, in 7 to. 10 revealed as the oblique beam 2 at the joint approach 25 over the hinge axis 24 on the clevis 23 is mounted pivotably. So include the fork cheeks 35 the cheeks 57 of the joint section 54 , where the hinge axis 24 in the imaginary tilt axis 21 below the sloping beam 2 runs. An essential difference to the joint approach 72 the second joint according to 3 and 4 However, this is that for pivotal mounting in the cheeks 57 not two axle bores, but two axial slots open at the bottom 65 are provided. In this way it is possible to use the sloping beam 2 at the joint approach 25 by mere touchdown on the joint axis 24 with the fork head 23 tiltable to connect. The hinge axis 24 can therefore already factory on the clevis 23 be pre-assembled. Also, in the two insides of the two cheeks 57 two guide grooves 66 incorporated, which are parallel to the sloping beam 2 run and through the axial slots 65 are interrupted. In the guide grooves 66 is a backup plate 67 inserted, for radial securing of the hinge axis 24 in the joint approach 72 is used. These are the guide grooves 66 immediately below the spacer sleeve 39 provided so that when inserted backup plate 67 , in particular from 10 and subsequently in 13 visible, the joint approach 72 no longer from the clevis 23 is solvable. The guide grooves 66 and the corresponding edges of the backup plate 67 are preferably designed so that the backup plate 67 by inserting is insertable and then holds self-locking.

In 11 a prefabricated assembly according to the invention is shown, as in the stand according to 2 is installed. The assembly includes especially the sloping beam 2 , the joint approach 25 the first joint 20 , the joint approach 72 the second joint connection 70 as well as the strut 3 and the joint body 92 ,

The two joint approaches 72 and 25 are as above 3 and 4 or too 7 to 10 described by means of the screws 78 respectively. 58 Non-rotatably longitudinally guided on the inclined beam 2 firmly attached. It is important that the joint approaches 72 and 25 already at her 1 and 2 apparent target positions are set, so that when exactly according to plan or tolerable deviating from the plan prop 1 the joint approaches 72 and 25 not have to be readjusted on site by the fitter. Otherwise, it is still possible, the joint approaches 72 and 25 by loosening, moving and locking to arrange from the target positions deviating correction positions.

It can also be seen that the second articulation 70 between sloping beams 2 and strut 3 how to 3 and 4 described about the hinge pin 81 already made, and that the joint body 97 at the bottom or at the other end of the strut 3 over the hinge pin 97 also already arranged.

The prefabricated assembly can be prefabricated as standard in large numbers factory or delivery side and delivered to the installation site of the open space system. For transport purposes is the strut 3 as shown at or near the slanted beams 2 worked. Particularly characteristic of the prefabricated assembly is therefore that the strut 3 for making the third hinge connection 90 according to 5 and 6 in a pivoting movement according to arrow 7 first unfold is.

In 12 and 13 is illustrated as the prefabricated assembly according to 11 making the first joint 20 on the prop 1 is arranged. Preparing became the support 1 first in the ground 4 according to 1 founded and then the platform 22 , the clevis 23 as well as the joint axis 24 according to 9 assembled. At this point it should be mentioned that also in 9 assembly shown may already be pre-assembled at the factory.

Next is in 12 to recognize how before connecting the prefabricated assembly on the support 1 is raised so that the axial slots 65 of the joint approach 25 above the hinge axis 24 of the clevis 23 are located. Subsequently, the prefabricated assembly is down in the direction of the arrow 8th between the fork cheeks 35 of the clevis 23 led, so that the two axial slots 65 up to the stop on the spacer sleeve 39 the hinge axis 24 seated.

For radial securing can then, as in 13 illustrates the fuse plate 67 in the direction of the arrow 9 in the guide grooves 66 and thus under the spacer sleeve 39 be pushed so that the prefabricated assembly is no longer from the clevis 23 or the support 1 unintentionally solvable.

In a further assembly step, the strut not shown here in detail 3 the prefabricated assembly of the inclined beam 2 folded away, the entire assembly around the tilt axis 21 if necessary, slightly tilted and then the third joint connection are made.

Finally shows 14 the module according to 11 by five terminals each 100 and 101 complements that for fixing the on the diagonal beam 2 arranged module support profiles 5 according to 1 are provided. In each case form one of the terminals 100 and 101 one of five pairs of terminals. Not clear is that the lower clamps 100 and the upper clamps 101 of each pair of clips on the module profile 5 on both sides provided retaining web can embrace.

The clamps 100 and 101 are in the undercut longitudinal groove 10 according to 4 and 10 Slidably mounted by sliding blocks. It is essential that the lower clamps 100 already arranged at their desired positions and designed so that a module support profile 5 tool-free by a fitter, preferably only by inserting or hooking the lower part of the holding web initially provisionally held on the inclined beam and then by tightening the clamps 100 is finally fastened. The upper clamps 101 are arranged slightly above their nominal positions, so that this placing the module support profiles 5 do not hinder. After mounting, the terminals can 101 solved if necessary, on the upper side of the retaining web of the module support profile 5 attached and also tightened.
