Description

50

The invention relates to a multiple, individually displaceable tracks that are suspended from a supporting frame Made of pliable material roofing for a sports field, a grandstand or the like., wherein the I. longitudinal edges of the individual, transverse to these longitudinal edges sagging tracks od in running rails. Like. Are guided. Such canopies are z. B. by the US-PS 28 28 756 became known.

In the case of canopies with individually suspended sheets, the tent skin is around that which occurs when there is wind To avoid hitting and the annoying noise associated with it, kept under tension, which means special Tension ropes, including those made of elastic material or those with tensioning devices, are made, which are stretched over these * 5 se in the throats of the individual tracks.

As a result, a complicated cut is chosen for the individual lengths of the tent skin must or that with a rectangular cut of the webs a wrinkling occurs, which leads to the formation of Water pockets, leads to the deposition of dirt or snow.

The invention is therefore based on the object Roofing of a sports field, for example a tennis court or a boxing ring, if necessary including grandstands, or the roofing of a grandstand alone to be carried out in such a way that for the webs of the tent skin can be used with simple cuts and the load on the supporting structure Hitting the tent skin and stressing the tent skin with deposits occurring in folds is avoided

will.

This is achieved according to the invention in that the tracks with parts of the supporting structure and / or in the case of tracks arranged in mutually inclined planes with each other by means of transversely to the longitudinal edges of the Tracks of extending tendons engaging in the apex area of the tracks are guyed.

This results in a flutter-free structure in a simple manner due to the tendons running transversely to the webs Bracing of the tracks reached.

Instead of individual tendons, the two sheets arranged in mutually inclined planes with each other connect and are distributed at a distance from one another over the length of two tracks, two such Tracks also by means of an additional track extending over the length of these tracks, a so-called Tension apron, be tensioned, which is longitudinally displaceable with respect to the two tracks.

The suspension of the tracks is expediently carried out on the upper chord of a longitudinal girder, on the lower chord in the Attack the tendons in the event of a web being braced on the shoring.

For areas the size of a tennis court or a boxing ring, for example, there is a roof advantageously from one extending between longitudinal members arranged at the same height middle track and one on each side of this middle part at an upper and a lower one Side member guided train.

Here, the lower longitudinal beams are advantageously compared to the upper longitudinal beams according to the Offset.

The longitudinal edges of the webs are expediently guided by means of the longitudinal beams Pivotably arranged running rails for double rollers provided on the edges of the tracks.

in the drawing is an embodiment of the invention Canopy shown in a schematic manner. It shows

F i g. 1 is a longitudinal side view of the supporting structure,

F i g. 2 shows a section through the supporting structure according to FIG. 1 after the section line 2-2 with drawn-in webs and accessories in opposite FIG. 1 enlarged view,

F i g. 3 that shown in FIG. 2 with "A" labeled detail, again enlarged,

4 shows that in FIG. 2 detail marked with »& <, also in an enlarged view.

The supporting structure consists of three supports 1 aligned with one another on each longitudinal side and on each end face two slightly longer supports 2 on which beams 3, 4 and 5 are supported. One in the plane of symmetry The truss arranged on the supporting frame is composed of the two struts 6 and the ridge carrier 7. on the supports 2 and the two nodes of the central

Leren binders lie on the side members 8, on which rails 9 are arranged pivotably about their longitudinal axis are. On these running rails you are: Longitudinal edges of a middle track 10 and two side tracks 11 and 12 hung.

In the case of the FIG. 2 and 3 shown embodiment are on the side members 8 obliquely arranged downwardly pointing tubes 19, which carry further rails 9 on a collar, on which tendons 13 and 14 are displaceably guided, which are attached to the track 11 or 12 or to the track 10.

On further running rails attached to the tubes 19 an additional group of tracks 15, 16 and 17 is arranged, especially in the cold season be pulled under the outer tent skin to counteract heat loss and the formation of Avoid condensation. These sheets are also made of translucent plastic, so that the Daylight enters the roofed room in a diffuse and undisturbed manner. These additional tracks do not need any Bracing, as they are not exposed to the wind or any debris.

As shown in FIG. 2 can be seen, the tubes 19 can also serve as a carrier of lights that are also perpendicular can be arranged hanging.

Instead of the in FIGS. The shoring structure shown in FIGS. 2 and 3 can also be used in this way be designed that the longitudinal beam 8 is designed as a narrow and high beam, the running rails for the tendons 13 and 14 are arranged on the lower chord.

The lower longitudinal edges of the side panels 11 and 12 are guided in running rails 9 which are articulated on the side members 3 and which are guided by a the side panels attached apron 18 are overlapped, over which the rainwater in the as Gutter serving carrier is initiated.
