Description
Technical field
The present invention relates to the building air-supported membrane structure that a kind of cinema uses, be specifically related to the building structure that a kind of inside has the smooth, spherical screen, this building structure is applicable to movie theatre or the venue of playing various spherical screen stereoscopic films.
Background technology
Present ball curtain has the hard ball curtain and inflates two kinds on software ball curtain.
One, the ball curtain made of hard material:
The ball curtain is to be prefabricated into an act plate in advance with metal material, through assembled.Earlier basic ring is connected with suspended chain, pillar, girder steel or foundation wall during installation, ball curtain keel, rack is installed on basic ring then, at last in certain sequence with prefabricated metal mask assembly unit piecewise to ball curtain rack.
Hard ball curtain structure complexity, manufacturing and difficult in maintenance, installation period is long, migration difficulty, construction cost height.Based on the specific version of hard ball curtain, its size is subject to processing the restriction with mounting condition, and up to now, maximum ball curtain diameter is 30 meters, and its installation period needed for 24 weeks approximately, and involved great expense.If the ball curtain is installed to other place, be easy to cause an act plate distortion in the transition process.Therefore the ball curtain that uses hard material to make is often all made fixed type ball curtain theater.
Two, the ball curtain made of flexible material:
The ball curtain adopts the flexible curtain material through cutting to be spliced, and the shape of cutting is through professional calculation software design.By the flexible ball curtain is fixed to ground, between ball curtain and ground, form confined space, with fan blower drawdown pressure inside and outside air blowing between ball curtain and the ground makes the ball curtain, it is spherical that the ball curtain is realized then.
The sound insulation and the heat-insulating property of flexible ball curtain are relatively poor, are unfavorable for that severe cold and heat weather use out of doors; Be the key that guarantees ball curtain steady operation owing to pressure reduction is stable simultaneously, so personnel's discrepancy, fan trouble, voltage fluctuation and instantaneous wind and rain all can cause the instantaneous vibration of ball curtain and influence viewing effect; The fan blower steady operation is required high, accident such as outage even can cause the ball curtain structure to collapse and can not use safely.Therefore the flexible ball curtain often only is used as provisional Popular Science Education equipment, the domestic examples of many successful of also not using the flexible ball curtain to use as permanent theater.
Summary of the invention
The purpose of this invention is to provide a kind of ball curtain, the venue that this ball curtain cost is low, be easy to install, be applicable to arbitrary dimension, can be because of unexpected factor affecting viewing effect and ball curtain structure, be convenient to severe cold and heat weather uses out of doors, simultaneously, both nonvolatil theater can be made, interim Popular Science Education equipment can be made again.
In order to achieve the above object, technical scheme of the present invention has provided a kind of software ball curtain, comprise metal support, outside surface at metal support is coated with the roofing coverture, it is characterized in that, curtain is located at the inside surface below of metal support by being distributed on draw-gear on the metal support, the bottom of curtain links to each other with the bottom of metal support, be provided with at least one extractor fan in the bottom of metal support, extractor fan outwards vacuumizes the space that makes between roofing coverture and the curtain and forms sealed chamber.
Principle of the present invention is exactly to rely in the sealed chamber of exhausting system between the curtain system of roofing covering system that is supported by shell system and exoskeletal supporting to produce stable negative pressure, thereby form stable tension force at ball scene plot face, and the ball curtain of dimensionally stable is provided thus.
Air-bearing form of the present invention makes the supporting structure of ball curtain very simple, only needs to be fixed to curtain on the collar tie beam and to open air pump to form the ball curtain automatically, thereby has shortened the installation and the dismounting cycle of ball curtain greatly.Curtain adopts flexible screen material to make, and can fold packing and transporting, makes the ball curtain be convenient to move, and simultaneously, curtain is prefabricatedly in factory to form an integral body, and size is not limited by mounting condition, thereby can make super large ball curtain than low-cost.
Because curtain is by the negative pressure shape balling-up curtain shape in the sealed chamber, this theater space that makes curtain form can be open, can not come in and go out because of personnel, air pressure fluctuation factor such as gate unlatching causes the ball curtain to produce to vibrate, influence viewing effect.
Because confined space---the existence of sealed chamber between curtain and roofing coverture significantly reduces the heat transfer area of indoor and outdoor, has better building heat preservation performance, thereby realize energy-conservationly, and reduce the air-conditioning expense greatly.Especially for outdoor SmartMovie, under weather in freezing winter and in sultry summer, have better economy and practicality.
If run into emergency conditioies such as outage, connect the equally distributed lifting rope of curtain and metallic framework, can keep the shape of ball curtain substantially, the ball curtain more can directly not fall earthward, and it is outdoor that personnel can be evacuated at leisure, avoids occurring security incident.
In sum, advantage of the present invention is: the venue that cost is low, be easy to install, be applicable to arbitrary dimension, can be because of unexpected factor affecting viewing effect and ball curtain structure, be convenient to severe cold and heat weather uses out of doors, simultaneously, both nonvolatil theater can be made, interim Popular Science Education equipment can be made again.
