Seamless spherical screen capable of providing large-span interior architectural space and preparation process thereof

Abstract

The invention discloses a seamless spherical screen capable of providing a large-span interior architectural space and a preparation process thereof. The spherical screen comprises a composite material outer film, a polyurethane heat insulation layer, a reinforced concrete thin shell and a projection screen layer which are successively composited from the outside in. The preparation process comprises the steps of enabling the bottom edge of the composite material outer film to be connected with an annular concrete pedestal; inflating the composite material outer film, wherein the composite material outer film bulges to form an inflated spherical film; coating an adhesive, and preparing polyurethane into the polyurethane heat insulation layer through a spraying process; installing a steel bar keel, and spraying concrete so as to form the reinforced concrete thin shell; and performing painting a screen coating material at the inner wall of the reinforced concrete thin shell so as to form the projection screen layer. According to the invention, the spherical screen and the spherical thin shell structure are enabled to be fused into an integral whole, a 360-degree omnidirectional seamless projection screen can be provided inside, and the spherical shape can provide an architectural space for virtual reality such as 3D, 4D and VR with a feeling of being personally on the scene.

AI Technical Summary

Benefits of technology

This patented new type of protective coverings called ball screens have been developed over recent decades ago. These covers allow buildings without any holes or cracks when they hit them. They also offer durability against environmental factors like sunlight exposures and severe winter temperatures. Overall, these technical featments improve safety, reliance, efficiency, energy savings, and overall performance capabilities of protected spaces such as homes, offices, stadiums, etc., making their design practicality even better.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the quality of a display device that uses domes like those described earlier. However, due to their shape, they have weakened physical strength when compared to regular screens. This can lead to issues during use at high altitudes where rain may damage them over time. Additionally, current methods involve adding extra layers between each layer to increase its stiffness without affecting image clarity.
