Embodiment Construction

[0027] A radially retractable roof structure, comprising: a radially telescopic network frame, a single-degree-of-freedom annular linkage mechanism is arranged outside the radially-expandable network frame, and the single-degree-of-freedom annular linkage mechanism includes a head-to-tail connection A regular n-sided bar composed of n straight bars 1, n is not less than 3 and not more than 720, and each straight bar 1 is provided with a link mechanism unit, and the link mechanism unit is composed of a built-in parallelogram mechanism Ⅰ and external parallelogram mechanism Ⅱ,

[0028] The built-in parallelogram mechanism I is composed of the first fixed rod, the first side rod 3, the first connecting rod 4 and the first end rod, and the first fixed rod is 1 / 2 straight rod 1, and the first fixed rod One end of the first side bar 3 is rotatably connected to one end of the first side bar 3, the other end of the first side bar 3 is rotatably connected to one end of the first connec...

Abstract

The invention discloses a radially retractable roof structure, which comprises a radially retractable net frame. A single-freedom-degree circular connecting rod mechanism is arranged outside the radially retractable net frame and comprises equilateral n-side polygon rod combination consisting of n straight rods connected end to end, wherein the n is not smaller than 3 and not larger than 720, each straight rod is provided with a connecting rod mechanism unit, and each connecting rod mechanism unit consists of an internal parallelogram mechanism and an external parallelogram mechanism. The radially retractable roof structure has the advantages that the roof is retracted by effect of the radially retractable net frame. During retraction of the roof, the equilateral n-side polygon rod combination outside the radially retractable net frame is fixed, supporting points on the equilateral n-side polygon rod combination of the radially retractable roof structure cannot be subjected to radial movement during radially retracting process of the roof structure, and thus, supporting conditions are simplified. In addition, since the roof is driven to retract by the aid of the single-freedom-degree circular connecting rod mechanisms, the quantity of driving devices is reduced.

Description

technical field [0001] The invention relates to a roof structure, in particular to an openable roof structure. Background technique [0002] In the past few decades, scholars from various countries have proposed many concepts of long-span retractable roof structure systems, some of which have been applied in the retractable roofs of large sports venues such as tennis courts, swimming venues, and track and field venues. [1] . American engineer Hoberman has been working on the research and design of the opening and closing structure since the late 1980s, mainly focusing on the application of the opening and closing structure. His representative work is Iris Dome [2-4] . Iris Dome is based on the Hoberman unit, which is composed of two equal bent corner beam units connected in the middle by a scissor hinge. When the two corner beam units rotate around the middle scissor hinge, the beam The included angle at the end remains constant. Using this property, n identical Hoberman...
