Software dome

Abstract

The invention provides a software dome, which comprises a metal bracket. A roof covering covers the outer surface of the metal bracket. The software dome is characterized in that: a curtain is arranged on the lower part of the inner surface of the metal bracket through traction devices uniformly distributed on the metal bracket; the bottom of the curtain is connected with the bottom of the metal bracket; the bottom of the metal bracket is provided with at least one air extracting device; and the air extracting device vacuumizes outwards to make a space between the roof covering and the curtain form an airtight chamber. The software dome has the advantages that: the software dome has low cost, and is easy to mount and suitable for stadiums with any size; the watching effect and the dome structure cannot be influenced due to accident factors; the software dome is conveniently used outdoors in cold and hot weather; and simultaneously, the software dome can be made into a permanent theater and also can be made into a temporary science education device.

Description

a soft dome technical field The invention relates to an architectural inflatable membrane structure for a movie theater, in particular to an architectural structure with a smooth spherical screen inside, which is suitable for theaters or venues that play various spherical screen movies. Background technique There are two types of dome screens: hard dome screens and inflatable soft dome screens. 1. Ball screen made of hard material: The dome screen is prefabricated with metal materials and then assembled. When installing, first connect the base ring with the suspension chain, pillar, steel beam or base wall, then install the dome keel and grid frame on the base ring, and finally assemble the prefabricated metal curtain pieces to the dome screen piece by piece in a certain order on the shelf. The structure of the hard dome is complex, difficult to manufacture and maintain, long installation period, difficult to move, and high construction cost. Based on the specific s...

AI Technical Summary

Problems solved by technology

The sound insulation and thermal insulation performance of the flexible dome screen is poor, which is not conducive to outdoor use in severe cold and hot weather; at the same time, since the stable pressure difference is the key to ensure the stable operation of the dome screen, personnel access, fan failure, voltage fluctuations and instantaneous wind and rain will cause The instantaneous vibration of the dome will affect the viewing effect; the blower has high requirements for stable operation, and accidents such as power failure may even cause the structure of the dome to collapse and cannot be used safely

Therefore, flexible dome screens are often only used as temporary popular science education equipment, and there are no successful examples of using flexible dome screens as permanent theaters in China.
