The axis of the surface of rotation does not have to be vertical either quay run. Furthermore, several such could also be used between the attachment points of the arms 46, 48 and 54, geometric shapes combined into one construction 56 of the fittings 26 and 28, while the outer. Ren partial areas 42 and 44 corresponding to the An-The rods 16 are all along the meridian lines 5 closing of the rods 16 and 20 in a ring-like manner Rotating surface arranged and extend from the horizontal surface portions delimit. While the zontal pull ring 12 to the horizontal pressure ring partial surfaces 42 parallel surface parts on two 14. A meridian line is defined here as the sides of the center piece 24, which exclude them Line of intersection of the surface of rotation with a surface portions formed by its axis of the partial surfaces 44 Level. The planes in which the rods are at an acute angle to one another, since the parallel ones 16 are preferably arranged so that arms 54 and 56 for the rods 20 like this on veralle Angle, the intersecting geodetic lines separated by adjacent planes are closed, are equal to each other, so that they lie in the surface of rotation.

In the case of the hemisphere shown, adjacent rods Each connection piece 26 and 28 has a mitti-16 limit the same sectors of the hemisphere. The 15 gene arm 46 and two side arms 48 on. the Rods 16 lie on geodetic lines of the rotating longitudinal side surfaces of the arms are corresponding to the surface, in the illustrated embodiment on the inner cross-section of the hollow terminal ends of the Great circles of the hemisphere. Bars 16 and 20 rounded to ensure a better fit. Each of the side arms 48 detic lines of the surface of revolution or great circles 20 and 56 is provided with a transverse screw thread Spherical surface. In the illustrated embodiment 50 provided near its outer end, which example is each of these geodetic lines running essentially tangential to the surface of revolution in which a rod 20 lies, defined by the spreader and in which a spreader device 52 and 60, respectively, in Intersection of the spherical surface and a plane, which form a clamping screw is screwed in, soft through the center of the spherical surface and two on as against a recess 53 and 61 in the middle The same horizontal parallel circle lying, loading arm 46 and 54 is supported. For actuating the clamping neighbors Knot pieces 18 goes. In this way, the hollow terminal ends of the screw have adjoining rods 20 close together a rods 16 and 20 at the corresponding points Openim the following statements called "connecting angles".

Angle which is slightly less than 180 °. 30 It has already been mentioned that, as a result of these geometrical relationships between neighboring bars 20, both of them include a connection between the various components of the truss angle, which is slightly less than 180 ° yes, these ring parts lie on different geodetic lines that intersect each other and maintain the same curvature,
which corresponds to the radius of the spherical surface. 35 This has the advantage during manufacture that each junction piece 18 (Fig. 3 to 6) has all components in only one direction around a ge-center piece 24 with two connecting pieces 26, on a common axis with the same radius of curvature, each of which is a tubular Rod 16 connected must be curved. Here is the connoisseur. Furthermore, two angles of application between two adjacent rods 20 are provided on the middle piece 24, on each of which a tube 40 differs from ring to ring of the skeleton. It has shaped rod 20 attached. It has been found on the rods that the change in this connection 16 is a retaining profile 30 (FIG. 3) and a retaining profile 32 is attached to each of the stanchions for any type of dome in verbs 20, which is an aluminum turn sufficiently large number of rings can be miniumstranggußstück. can be kept to a minimum. In a hemispherical The retaining profiles 30 and 32 are used to support the 45-shaped dome structure with the following data, the outer skin of the structure-forming panels is, for example, the difference in the connection angle 34 z.

It has been found in practice that a single mold is sufficient for all node pieces 18 and that the differences that arise for the connection angle in the individual rings, in simpler Way can be achieved in that the tensioning screws correspondingly more or less strongly attracted.

The rods 16 and 20 are formed by tubes, preferably made of aluminum, with a circular cross-section. They are each provided with longitudinal ribs 62 and 63, which are used to attach the retaining profiles 30 and 32, respectively are provided with transverse holes 64 and 65, respectively.

Two parallel legs extend from a base body 66 or 80 of the holding profiles 30 and 32 67 or 82 and take the longitudinal rib 62 or 63 of the associated rod 16 or 20 between them on. The legs 67 and 82 are provided with transverse holes 68 and 84, which are connected to the holes 64 and 65 are aligned in the longitudinal ribs 62 and 63, respectively. The holes 64 and 65 of the longitudinal ribs 62 and 63 and the holes 68 and 84 of the legs 67 and 82 are penetrated by the connecting pin 70 and 84, respectively. Furthermore, the base body 66 or 80 is provided on its upper part with a head part 72 or 88, on its outer top surface with a longitudinal groove 73 or 90 with several parallel ribs for the engagement of screws for securing the terminal strips 36 is provided. After all, there are two Arms 74 and 92 are provided, which protrude laterally from the base body 66 and 80 and essentially are directed perpendicular to the head part 72 and 88 and to the legs 67 and 82, respectively. The arms 74 and 92, respectively, have flat sub-panels and top surfaces. The plates 34 rest on the latter. Near the Head part 72, the arms 74 are provided with small indentations, which extend in the longitudinal direction of the retaining profiles 30 extend and form channels through which, between the plates 34, the holding profiles 30 and the terminal strips 36 infiltrated water can be drained. Between the plates 34, the Holding profiles 30 and 32 and the clamping strips 36 are also strip springs 75 with three arms (FIG. 3). One arm of each spring 75 is inserted into the groove 73 or 90, while the other two arms the head part 72 or 88 and the side edge of the plates 34 press. Over the length of the retaining profiles 30 or 32 are a plurality of such ribbon springs 75 distributed so that relative movements of the plates 34 and the Holding profiles 30 and 32 are limited to a minimum.

Each retaining profile 30 is also provided with two flanges 76 which extend from the lower ends of the Legs 67 extend transversely to the longitudinal direction of the retaining profile 30 and essentially parallel to the

ίο arms 74 run. The flanges 76 have one slightly denser cross-section than the corresponding portions of arms 74 and are at their ends each provided with a band-like extension 78 extending in the longitudinal direction. In this way channels are formed for the drainage of condensation water.

Each retaining profile 32 is only provided with one flange 94 with respect to the retaining profile 30, which, however, has no shoulder at its end. The flange 94 is attached to the leg 82 at a distance from the lower end thereof, so that it fits over the flange 76 of the retaining profile 30. Furthermore, the ends of the arms 92 are machined so far that the ends of the arms 74 of the associated holding profiles 30 can engage. The flange 94 of the retaining profile 32 and its leg 82 form a channel into which ^{water occurring on the inner surface of the dome Konder 1} and can flow down from there. This is facilitated by the fact that the holding profiles 32, which are arranged on great circles of the hemispherical dome structure, have their highest point between the two connecting parts.

Each of the plates 34 rests on the flat top surfaces of the arms 74 and 92 of four, respectively holding profiles 30 and 32 arranged like a frame. Between the board edges and the headboards 72 and 88 respectively, a gap remains. Each terminal strip 36 has two longitudinal grooves 96 on the underside provided, which in the assembled state of the terminal strips 36 each over adjacent plates 34 lie. Through holes in the terminal strips 36 which are arranged at suitable distances from one another Fastening screws 98 extend, which are inserted into the grooves 73 and 90 of the holding profiles 30 and 32, respectively are screwed in and fasten the terminal strips 36 in this way. The between the grooves 96 of the Terminal strips 36 and the panels 34 remaining gap is sealed with a suitable sealing material 100, e.g. filled with a vulcanized butyl sealing tape.
