Abstract
The utility model relates to a dome-screen rack used for dome-screen in cinema. The utility model comprises a dome rack which is smaller than a hemisphere (180 degrees) and a fixed vertical rack connected with the external sphere of the dome rack; the difference is that the dome rack consists of a latitude component and a longitude component which are connected with each other by a joint connecting plate and a dome rack with latitude and longitude grid structure is formed; the port of the dome rack is equipped with a circular dome-screen coronal opening and the ends of the latitude and longitude components are both connected with the dome-screen coronal opening. The utility model has the beneficial effect that the latitude and longitude components form the dome rack and the joint connecting plate is used for joint connection; the dome structure is simple and rational which can has good strength and rigidity and strong stability and is convenient for construction and installation; the cost is low; the vertical dome rack arranged at the dome-screen coronal opening is more comfortable for viewers to watch and at the same time is convenient for the collocation of seats and other facilities in the cinema.
Description
Technical field
The utility model relates to a kind of ball curtain grid structure that is used for the screen of ball screen cinema ball-type.
Background technology
Ball curtain rack is the important component that constitutes ball-type screen in the ball screen cinema.Because ball curtain rack diameter is bigger, in order to guarantee the strength and stiffness of ball curtain rack, existing ball curtain rack mostly adopts the structure of M shape or triangle member and sphere nodes, structure is complicated, the corresponding increase of the number of components, engineering construction and installation are all cumbersome, and the cost of making is higher.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and provide a kind of structure that advantages of simple comparatively is set, be convenient to the ball curtain rack of constructing and installing.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: comprise less than the spherical net brace of hemisphere (180 °) and the fixedly stand that links with the spherical net brace spherical outside surface, its difference is that described spherical net brace is formed with interconnecting through node web joint 7 through line components 4 by parallel member 5, constitute the spherical net brace of fictitious graticule structure, port at spherical net brace is provided with circular ball curtain hat mouth 3, all joins with ball curtain Guan Kou through the termination of line components and parallel member.
Press such scheme, the sphere radian of described spherical net brace less than hemisphere is 155～165 °.
Press such scheme, described ball curtain Guan Kou plane and surface level are perpendicular; Described fixedly stand is coupled to each other by column 1 and arc cross bar 8 and upper frame 6 and constitutes, and fixedly stand links by the node web joint 7 that connects strut 2 and spherical net brace.
The beneficial effects of the utility model are: 1, adopt the longitude and latitude member to constitute spherical net brace, and carry out the connection of node by the node web joint, spherical frame construction like this is provided with advantages of simple, not only have strength and stiffness preferably, stability is strong, and be convenient to construction and low cost of manufacture is installed; 2, the ball curtain rack that ball curtain Guan Kou is vertical can make to be watched more comfortablely, also is convenient to simultaneously the configuration at seat and other facility in the movie theatre.
