Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and particularly to a large-span BOX-shaped screen and a construction method thereof. Background Art
[0002] The BOX-shaped screen is mostly used in multimedia exhibition halls and generally adopts a four-fold screen. The four-fold screen is composed of three walls and the ground. The orthographic projections of the three walls are in a U shape, aiming to create a visual impact of naked-eye 3D and bring a better immersive experience to the audience. At present, more and more exhibition halls adopt the BOX-shaped screen for cultural and content promotion.
[0003] At the present stage, the most commonly used form of the domestic four-fold screen is the form of screen + projection, that is, screens are set on the three walls and the ground, and finally projected onto the four screens. Although this construction is simple and fast, it is mostly temporarily erected. When large-span projection is required, it is difficult to accurately locate the installation positions of multiple projectors, and the projection effect is poor. At the same time, the clarity of the projection form is poor; in addition, there is also a form of connecting LED display screens on the three walls and the ground. This form has high clarity, but for a large multimedia exhibition hall, a large-span LED display screen adapted thereto is required. Such a large-span LED display screen is expensive in cost, and both the transportation and construction difficulties are relatively large. In addition, if it is damaged and cannot be repaired later, it can only be scrapped as a whole, resulting in a large cost. Summary of the Invention
[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a large-span BOX-shaped screen and a construction method thereof. The wall screen is formed by splicing multiple wall screen units, and the ground screen is formed by splicing multiple ground screen units, ensuring the clarity.
