A Radial Overall Opening and Closing Roof Structure

Abstract

The invention relates to a radial whole retractable roof structure. The radial whole retractable roof structure comprises movable roofs, transmission connecting rods and fixed roofs. A whole retractable roof only has one degree of freedom and is radially wholly opened and closed in the opening and closing processes, the movable roofs are connected together through the transmission connecting rods to form a whole, the movable roofs move along rails arranged on the fixed roofs through universal balls to achieve the retractable functions. A variable height intersection truss system is adopted in the movable roofs to form a space stress structural system, and then the dead weight of the movable roofs is reduced. The rails are of a circular arc shape and reasonably arranged, and therefore the rails are prevented from being exposed out of a visual field when the roof is opened. Joints for connecting the movable roofs, the transmission connecting rods and the universal balls are designed, and rotation between the movable roofs and the transmission connecting rods can be achieved to further achieve the retractable function. The radial whole retractable roof structure is novel in retractable mode, reasonable in structure stress, convenient to drive and control, and good in application prospect.

Description

Technical field [0001] The invention relates to an opening and closing roof structure applied to a stadium building roof system, which has the characteristics of radial integral opening and closing, and can fully or partially open and close the roof according to changes in weather and the needs of the stadium. Realize the mutual conversion between indoor and outdoor spaces. Background technique [0002] The opening and closing roof structure is a new type of space structure that has gradually emerged from the 1960s. It can fully or partially open and close the roof according to the changes in weather and the use of stadiums, so that the stadium can convert between indoor and outdoor spaces and make full use of nature. Conditions, the use and protection of venues, and at the same time to ensure that the event will be held on schedule. The opening and closing roof structure includes three parts: movable roof, fixed roof, and drive control system. Each part has its own characterist...

Problems solved by technology

[0003] So far, retractable roof structures such as Toronto Skydome, Oita Stadium, New Pacific Northwest Baseball Stadium, and Shanghai Qizhong Tennis Center have appeared in various parts of the world, but the research on retractable roof structures at home and abroad is still in its infancy , there are still deficiencies in the relatively simple opening and closing methods, immature calculation and analysis methods, and no unified design criteria.
