Definitions
- the invention relates to a device and a method for fastening surface elements to a support structure, in particular a lenticular support structure, preferably a space frame.
- the surface elements may be cover elements or roof elements for roof structures as well as facade elements or wall elements for wall constructions. Suitable for this purpose are metal elements as well as glass panes or surface elements made of other materials, for example plastics.
- Supporting structures or space frameworks are used, for example, in roof and wall constructions.
- the supporting structures or room frameworks themselves are typically constructed of a modular system of rod elements and node elements, wherein the rod elements are connected to each other in the creation of the framework through the node elements.
- Spatial frameworks are usually constructed in two layers, three layers or multiple layers, i. Two, three or more truss levels are connected by diagonal bars.
- Such a modular system for the creation of space frameworks is mainly known by the company MERO-TSK International GmbH & Co. KG located in Würzburg / Germany. In the roof and wall construction and single-layer supporting structures are used.
- the floor-facing side of the supporting structure or space framework i. the lowest truss level, referred to as bottom chord
- the side facing away from the ground i. the uppermost truss level is called the upper chord.
- BESTATIGUNGSKOPIE Roof constructions often require roofing of the supporting structure or of the space framework.
- a covering is attached to the upper belt and / or the lower belt.
- This covering is formed from a large number of surface elements (cover plates, lining elements) which are fastened to the supporting structure or to the space framework.
- cover plates, lining elements which are fastened to the supporting structure or to the space framework.
- this device and this method should allow a simplified and thus cost-effective installation of the surface elements with little staff.
- the device according to the invention for attaching surface elements to a supporting structure comprises at least one attached to the support structure or to be mounted base plate (also: support plate). At least a first surface element and at least one second surface element are at least partially placed or placed on this base plate. Furthermore, the device comprises at least one holding device arranged on the base plate for fixing the surface element to the base plate. The holding device, in turn, comprises a rotational lock, which is designed to fix the first surface element and the second surface element.
- the first surface element in a first position of the rotary locking the first surface element can be placed on the base plate, in a second position of the rotary locking is the first floor chenelement fixed to the base plate and the second surface element can be placed on the base plate, and in a third position of the rotation locking the first surface element and the second surface element are fixed to the base plate.
- the device allows a stepwise attachment of the surface elements. It must not be placed simultaneously two surface elements and then fixed by means of twist lock. Rather, the device according to the invention makes it possible for these two surface elements to be applied and fixed not simultaneously, but successively, even though the rotation lock is provided for the fixation of two surface elements, i. Initially, the first surface element can be applied and fixed via the rotation lock and then the second surface element. As a result, the mounting of the surface elements is much easier.
- the device according to the invention thus enables a simple and less personnel requiring installation of the surface elements. As a rule, one person should be able to carry out the installation, with large dimensions of the surface elements in the meter range, two fitters should suffice.
- the simple attachment allows a time-saving installation, both in a mounting on the upper flange or on the lower flange of a roof construction as well as in mounting to wall or facade constructions. Overall, it is thus possible to carry out the attachment of the surface demerage by means of the device according to the invention in a cost-saving manner.
- the advantages of the invention are based on the ease of handling the twist lock. All components required for fixing and fixing the surface elements are already present on site and no longer need to be arranged in a time-consuming manner.
- the assembly is simple by rotation of the rotary latch from the first position to the second position and finally from the second position to the third position.
- the surface elements may be, for example, metal plates, eg stainless steel plates. These are suitable, inter alia, to form a shadow roof.
- the surface elements can be perforated in a suitable manner, for example, perforated plates or lock plates can be used.
- the surface elements may also be glass plates, for example pure glass plates or metal-enclosed glass plates.
- the node elements and rod elements of the supporting structure or truss are usually made of steel, in particular of galvanized steel.
- the node elements and / or the rod elements may be made of aluminum, stainless steel or stainless steel.
- the rod elements can furthermore consist of fiber composite material, for example of carbon fiber reinforced plastics (also: CFRP) and / or of glass fiber reinforced plastics (also: GRP), or comprise these.
- the rotary lock comprises a circular locking disk rotatably mounted about its center axis oriented perpendicular to the disk surface and having at least one preferably at least substantially rectilinear flattening on the disk periphery.
- the straight flattening thus represents a section along a chord
- the locking disc is in this case a circular segment with a center angle greater than 180 °
- the circumference of a circular arc and the aforementioned flattening is formed.
- the circular arc of the locking disc engages in the second position of the rotary locking in a recess of the first surface element and engages in recesses of the first surface element and the second surface element in the third position of the rotation lock.
- the flattening of the locking disc is aligned parallel to an edge of the first surface element. Furthermore, it can be provided that engages in the second position of the rotation locking the circular arc of the locking disc in a recess of the first surface element and the flattening of the locking disc is aligned parallel to an edge of the second surface element. Finally, it can also be provided that engages in the third position of the rotary locking of the circular arc of the locking disc in the recess of the first surface element and in a recess of the second surface element.
- the locking disc for the transition from the first position to the second position and from the second position to the third position is rotatable clockwise or counterclockwise.
- the locking disc may have a stop which defines the third position of the rotational locking by its tarnishing against the first surface element, since the starting a further rotational movement of the locking disc is prevented.
- the locking disc on and / or in the region around its radius center on a recess, via which it is attached by means of a fastening screw to the base plate. Furthermore, it can be provided that in the second position of the rotary lock in a non-tightened state of the fastening screw, the first surface is fixed or held by the locking disc to the base plate, and that in this case the locking disc to the fastening screw is rotatably attached to the base plate.
- the first surface element and the second surface element are fixed or held by the locking disc on the base plate, and in that case the locking disc rotatable about the mounting plate to the base plate is appropriate. It can also be provided that in the third position of the rotary lock in a tightened state of the fastening screw, the first surface element and the second surface element are pressed firmly against the base plate by the locking disc and thereby secured to the base plate, and in that case the locking disc is fixed, in particular non-rotatable, is attached to the base plate.
- the attachment or attachment of the surface element to the base plate is formed reversible. For example, by loosening or loosening the fastening screw, the rotatability of the locking disc can be restored, and a turning back into the mounting position of the rotary lock then allows the disassembly of the surface element.
- a further development of the invention provides that a spring element, in particular a spring element surrounding the fastening screw, is arranged as a spacer between the base plate and the locking disc. This ensures that the locking element is ready in the desired height above the base plate, so that it can be screwed, for example, without further adjustment directly into corresponding recesses of the surface elements at the appropriate height above the base plate. Also, the spring element allows pre-assembly of the base plate, i. the holding devices can already be preassembled on the base plate, the twist-lock is ready for use immediately on site.

- the overlying corners are fixed or fixable by two holding devices.
- the other corners of the surface elements rest on other, in particular adjacent base plates.
- the advantage in this case is in particular that corners can be fixed and fastened particularly securely and stably by two holding devices, in particular by arranging a respective holding device on the two edges of the planar element adjoining the corner.
- the rotation lock and thus the holding device for simultaneous fixing of two surface elements is formed on the base plate, corresponds to the provision of two holding devices per corner of a surface element, the number of holding devices on the base plate, the number of surface elements to be applied there.
- the fixing of the surface elements to the base plate takes place positively and / or non-positively.
- the first and second surface elements on their bottom side facing the base plate have a contact area which is intended to rest on the base plate.
- This area is at least partially convex shaped, that is arched outwards, in particular with a predetermined radius of curvature.
- an edge of the recess facing the base plate in the surface element is convexly shaped with respect to the surface element, i. the recess becomes narrower towards its center here, the surface element is arched into the recess.
- the radius of curvature here corresponds to the aforementioned radius of curvature of the support area.
- the two aforementioned embodiments prove to be advantageous in modern roof structures in which no flat roof design is provided, but rather free-shaped roof surfaces are desired, such as roofs with bends, vaults or wavy roofs.
- This can lead to the individual surface elements having to be arranged inclined or tilted relative to one another and relative to the base plate. It is therefore an attachment for the surface elements required that allows a tendency of adjacent surface elements against each other and also a tendency of individual or all surface elements relative to the base plate.
- the convex curvature or curvature of the support edge on the underside of the surface element allows an inclination of the surface element relative to the base plate, without causing an undesirable significant displacement of the actual support surface.
- the surface element rests on the base plate even when tilted or close to the holding devices, so that the inclination is maintained even when the fastening screws are tightened, without any tensions or stresses occurring within the surface element.
- This result is further supported by the convex curvature of the lower edge of the recess of the surface element, since in this way, the locking disc always optimally engages this edge and thereby reliably and stably against the surface of the surface element. pressed sisplatte and thus attached to it.
- the surface element is a plate with lateral raised edges.
- the support area is formed on an edge of the upstand opposite the plate.
- the recess may then be arranged in the surface element in the lateral upstand.
- the rotary lock in particular the locking disc, recesses and / or projections, via which the rotational movement of the locking disc by means of a corresponding with these recesses and / or projections tool is feasible. This facilitates the assembly.
- An embodiment of the invention provides that the base plate for supporting a plurality of surface elements, in particular of two or four or six or eight surface elements, is formed. Furthermore, a corresponding number of holding devices can be arranged on the base plate, in which case the rotational locking of each holding device is designed for fixing two surface elements. Further, in this case, each surface element is fixed or fixable by two holding devices on the base plate.
- the supporting structure is a single-ply or two-ply or three-ply or multi-ply space framework comprising rod elements and node elements and the base plate is fastened to one of the node elements, in particular via one or more spacer elements and / or via a ball joint.

- the locking discs 23 of the holding devices 21 engage in recesses 14 in the lateral raised edges 32 of the surface element 13. This engagement takes place via a corresponding rotation of the respective locking disc 23.
- FIG 9 and FIG 10 show in plan view eight or four according to the invention via a common base plate 20 fixed to a space frame 10 surface elements 13.
- the difference lies in the number of each resting on the base plate 20 surface elements 13
- FIG 9 shows the already mentioned 10 shows the likewise already mentioned second type of base plates 20 with four holding devices 21 for the fixation and fastening of four surface elements 13.
- FIG. 9 and FIG It can be seen that each corner 15 of the surface elements 13 is fixed and fastened by two holding devices 21.
- each retaining device 21 is designed for fixing and fastening two surface elements 13. Accordingly, the number of holding devices 21 on a base plate 20 corresponds to the number of surface elements 13 to be mounted on this base plate 20.
- rotational locking means are the retaining devices 21 in their fixing position, specifically in their third position, in which both surface elements 13 are fixed.
- This third position is defined by the stop 30 of the locking disc 23, which - as shown in FIG 9 and FIG 10 - abuts against one of the surface elements 13 and thus prevents further rotation of the locking disc 23 in the clockwise direction.
- Further details of the attachment of the surface elements 13 by means of the illustrated embodiment of a device according to the invention show the illustrations in FIG 11 and FIG 12.
- the detailed structure of the holding means 21 is identical in FIG 9 and FIG 10, FIG 11 thus shows a cross-sectional view along the Line AA in FIG. 9 as well as in FIG. 10.
- FIG. 12 shows a cross-sectional view along the line CC both in FIG. 9 and in FIG. 10.
- FIG. 11 the fastening of the base plate 20 to the node element 11 can be recognized by means of the fastening devices 46a and 46b.
- the holding devices 21 and their interaction with the surface elements 13 can be seen in FIG. 11 and FIG.
- FIG 12 shows the interaction of a holding device 21 with two surface elements 13, a first surface element 13a and a second surface element 13b.
- the first surface element 13a has a first edge 16a and a first recess 14a in this first edge 16a
- the second surface element 13b has a second edge 16b and a recess 14b in this second edge 16b.
- the locking disc 23 engages in both recesses 14a, 14b of both surface elements 13a, 13b and fixes them to the base plate 20.
- FIG 11 shows a further advantageous embodiment in connection with the device for fixing surface elements according to the invention.
- Roof structures in waveform require a corresponding shaping of the covering 40. Accordingly, therefore, if necessary, the individual surface elements 13 against each other inclined to the base plates 20 must be created. In order nevertheless to obtain the most optimal fastening and a suitable support area of the surface elements 13 on the base plate 20, a convex curvature 48 is formed on the underside 17 of the surface elements 13 around the support area 18, as shown in FIG.
- This convex curvature 48 allows tilting of the surface elements 13 relative to the base plate 20, wherein in this case a support area 18 in the region of the respective holding devices 21 is maintained, so that a stable attachment of the surface element 13 even when tilted relative to the base plate 20 while maintaining the inclination and without causing internal stresses or loads of the surface element 13 is possible.
- this edge 19 has a convex curvature 49 which is directed into the recess 14, i. the recess tapers towards its center.
- the radius of the curvature 49 of the lower edge 19 of the recess 14 in this case corresponds to the radius of the curvature 48 at the edge 33 of the upstand 32 of the surface element 13. This ensures that the locking disc 23 even with a tilt or inclination of the surface element 13 relative to the base plate 20 always in a central region and not only with an edge on the lower edge 19 of the recess 14 engages.
- FIGS. 13 to 25 show, as a sequence of illustrations, the mode of operation of the already explained exemplary embodiment of a device according to the invention for fastening surface elements to a space frame. They illustrate the individual assembly steps.
- the base plates 20 are in this case already in the intended manner to the node elements 11 of
- the base plate 20 is preassembled, the holding devices 21 are attached to the base plate 20 via the fastening screws 27, which have not yet been tightened, the locking discs 23 of the rotary locks 22 are moved over spring elements 28 at the desired spacing and in the desired orientation above the base plate 20 held.
- the locking disk is preferably already or possibly now aligned such that the flattening 24 is oriented parallel to the edge 16a of the first surface element 13a to be applied first (see FIG. 13). This is referred to as the first position or mounting position.
- the first surface element 13a can be applied to the base plate 20 in the intended position and optionally also in an inclination.
- the locking disc 23 After applying the first surface element 13a, the locking disc 23 is rotated clockwise (in plan view) to its second position, optionally with the aid of a special tool according to FIG 26.
- the circular arc 25 of the locking disc 23 engages in the first recess 14a of the first surface element 13a and fixed
- the flattening 24 of the locking disc is oriented in such a way that the flattening 24 is aligned parallel to the edge 16b of the second surface element 13b to be applied (see FIG. 14 and FIG. 15).
- the locking disc is rotated further in the clockwise direction (see FIG. 16), again if necessary with the aid of the special tool according to FIG. 26, until the abutment 30 abuts against the first edge 16a of the first surface element 13a and thereby a further rotation is prevented (see FIG 17).
- the circular arc 25 of the locking disc 23 engages both in the first recess 14a of the first surface element 13a and in the second recess 14b of the second surface element 13b, so that both surface elements 13a, 13b are fixed to the base plate.
- This third position is shown in FIG 18 again in a side sectional view.
- Locking disc 23 firmly against the lower edge 19 of the recesses 14 a, 14 b of the surface elements 13 a, 13 b pressed (see FIG 19). As a result, the surface elements 13a, 13b clamped between the locking disc 23 and the base plate 20 and thus fixedly secured to the base plate. Now also the locking disc 23 is no longer rotatable, but also fixedly fixed on the mounting screw 27 to the base plate 20. The toothed disc 42 prevents the loosening of the locking disc 23.
- the spring element 28 is optionally compressed during tightening of the fastening screw 27.
- the contact of the surface elements 13a, 13b is not directly to the base plate 20, but via the damping element 29, a Teflon disk 29th
- the self-locking lock nut 43 which is already preassembled on the fastening screw, is now tightened (see FIG. 20).
- FIGS. 21 to 24 show an optional possibility of attaching a wire 50 (also known as a wire rope) for connecting the surface elements 13 applied to a base plate 20 as additional securing means.
- a wire 50 also known as a wire rope
- the wire 50 is threaded through the recesses 14 in the already applied surface elements 13 (see FIG. 21 and FIG. 22).
- the wire 50 is threaded through the recesses 14 of the not yet applied surface element 13 (see FIG. 23) and subsequently twisted at its ends (see FIG. 24), if necessary with the aid of a tool or a tensioning device.
- FIG 25 shows the final state in which all provided surface elements 13 are attached to the base plate.
- FIG 27 shows a specific embodiment of a device for fixing surface elements 13 according to the invention, designed and determined for edge regions of a space frame.
- a surface element 13 is mounted only on the left side in the figure, on the right side ends the space frame and thus the roofing.
- the holding device 21 shown is in turn a twist lock 22 with locking disc 23 according to the above explanations.
- the attachment to the base plate 20 takes place in the manner described via the fastening screw 27.
- the holding device 21 shown must fix and fasten only one surface element 13, the counter support is missing through a second surface element.
- a support element 51 or an elevation is provided on this special edge base plate 20, on which the locking disc is fixed by rotation and / or can support in the attachment by tightening the mounting screw.
