Similar to the first exemplary embodiment. By additionally closing other openings, tubular openings and locks of the stadium 20 are provided on supports 122 on the guide sides 124 and 125. In contrast to the above-described manner, a substantially above the first exemplary embodiment are in the case of the two-airtight room. Several exemplary embodiments parallel and outside of the bladder 111 generate an overpressure which lifts the roof supports 122 additional guides 124 or skin 56 from the pull cables 51, 52 and 53 and arranges it 125 for guide members 127 and 128 , respectively. Above the support structure 26, 29 like a hallway, each arching in pairs transversely to the direction of actuation (see FIGS. 1 and 2). Are connected to each other by safety valves by suspension ropes 129. The overpressure can also be maintained in a roof skin 131 in the order of magnitude of approximately 0.0175 kg / cm ² when the carrying ropes 129 are heated. As indicated in FIG. 13, the roof skin 15 can be made up of several web parts in one piece or 128 essentially similar hanging cases by applying adjacent guide members 127 56. In addition, the curvature of the ten can be formed (see. Fig. 11).

Roof skin 56 by shaping and material exclusion To close the roof skin 131, which is not set accordingly, in particular by the manner shown in more detail with the fixed side 134 in the suspension cables 57 with a tubular plastic 20 is essentially airtight, is on both sheathing 58, the Reinforcing strips 61 guide sides each have a pull rope 140 that is only glued to the roof skin 56 and is firmly connected to the first guide member 127 or 128 on the closing straight line, in the longitudinal and transverse directions as well as in the edge of the roof skin 131 and in the direction of diagonals extending and other guide members 127 and 128 each on the sliding side along the circumference and in the first or 25 tend, in the direction of the closing side 135, the second third of the roof skin 56 as an oval or circle to a cable drum drive 136 or 138 to form running reinforcements, each surrounding a cable drum drive 137 and 139 espult, support each other in nodes (cf. Starting with the first fold on FIG. 14). Closing edge of the roof skin 131, the folding according to and by reference numeral 105 is also shown in FIG. 2 a 30 after lifted and ultimately the closing edge on at least the closing side 32 of the support structure of the closing side 135 - similar to the first protective screen indicated, the temptation example - is braced and continuous so that updrafts particularly seal the roof skin 56.

especially during the adjustment process, from which the sealing on the guide sides is required to tear loose the support structure. 35 by actuation of actuators 145, with Kolin closed position also carry Faltseile 95, 94, 93 benstangen 146 engage on pivoting levers 142 and 92 (see. In particular FIG. 4), each in one end of each of the guide 124 and Areas above the traction cables 50 to 54 with lower 125 is articulated in a pivot bearing 143 and different lengths, according to the size of the other end staggered with a section of a fold, connected to the roof skin 56 4 ° terminal strip 144 is connected to the side of above, to reinforce. and outside the circumference of the roof skin 131 against the

When the roof skin 56 is drawn in, it presses out of the closing support 122.

The arrangement is made by five drive motors 88 of blower 150 and five folding devices 82 to 86 via five belts essentially correspond to the first exemplary embodiment drives 89 each four pulleys 91 for the game, however, the lower ropes 92, 93, 94 and 95 such a mutually different arrangement of the carrying cables 129 is driven by correct that on the one hand the differences in FIG .
the stretched length of the roof skin 56 in the areas It does not matter what material the roof skin is composed of over the respective traction ropes 51, 52 and 53 , for example, the drives of the pulleys 50 can be made of plastic or some other fabric with a 91 first for the folding ropes 92, then for the folding ropes vinyl or neoprene rubber cover 93, then for the folding ropes 94 and lastly for the folding ropes, but the tensile strength should be greater than rope 95 in a manner not shown 14 kg / cm ² , the dead weight approximately between the coupling or be switched off when the 338 to 2370 g / m ² are in each case, the moisture absorption- corresponding fold of the roof skin 56 within a 55 tion factor of less than 5% of the dead weight betra-cover 98 im Area of the fixed side 31 of the supports, furthermore the material is at least made of a translucent construction. be an anti-ozone compound as a protection against the second embodiment having in accordance with the ultraviolet radiation, and at least FIGS. 10 to 12 is cold-resistant with 116 Veranstaltungszentrurn to -40 ° C, designated ie foldable and, in principle, in which a part of canopy 118 60 be fireproof.
