Embodiment Construction
[0021] Hereinafter, the present invention will be described in more detail with reference to the drawings in the specification:
[0022] Such as figure 1 As shown, a planar radial opening and closing roof structure 1 is shown. The planar radial opening and closing roof structure 1 is composed of 3 circular chain scissor mechanisms 2 and 16 radial chain scissor mechanisms 4. Among them, the circular chain scissor mechanism 2 is composed of 48 circularly symmetric scissor hinge units 3, and the circular chain scissor mechanism 2 is evenly spaced in the radial direction; the radial chain scissor mechanism 4 is composed of 14 diameters. It consists of a symmetrical scissor hinge unit 5, and the radial chain scissor mechanism 4 is evenly spaced in the circumferential direction. In addition, the radial chain scissor mechanism 4 extends to a certain length of the outermost circumferential chain scissor mechanism, and is fixed to the hinge support 7 with only vertical rotation freedom. ...

The invention discloses a planar retractable roof structure, which is composed of two or more ring-chain shaped scissor mechanisms and more radial-chain shaped scissor mechanisms. The ring-chain shaped scissor mechanisms are arranged concentrically, and the radial-chain shaped scissor mechanisms are radially arranged along a circular ring formed by the ring-chain shaped scissor mechanisms. The ring-chain shaped scissor mechanism is formed into a ring shape by connecting a plurality of circular symmetric scissor hinge elements end to end. The radial-chain shaped scissor mechanism is formed into a linear shape by connecting a plurality of radially symmetric shear hinge elements end to end. The radial-chain shaped scissor mechanism and the ring-chain shaped scissor mechanism are connected through the second connecting rod end portion of a radial symmetric shear hinge element and the first connecting rod end portion of a circular symmetric scissor hinge element, and the radial-chain shaped scissor mechanism extends out of the end portion of the outermost ring-chain shaped scissor mechanism. The planar retractable roof structure can stretch out and draw back freely, has large stretching rate and strong vertical stiffness, is reasonable in structure and simple in design and construction, and is especially suitable for the buildings with medium and small spans.
Description
Technical field [0001] The invention relates to a plane and radial opening and closing roof structure, in particular to a plane opening and closing roof structure with a radial ring chain shear type mechanism. Background technique [0002] The opening and closing roof structure is a new type of structure developed in the past half a century, which can partially or completely open and close the roof according to the changes of the atmosphere and the needs of the building. The main feature of the opening and closing roof structure is to have two stable configurations: fully closed state and fully expanded working state. The roof needs to be moved during the normal use phase and has multiple different stress states. Compared with the conventional building structure, the design and construction are more complicated. [0003] Deployable scissor hinge structure is a spatial structure based on scissor hinge unit, which can design colorful geometric shapes. This structure becomes a tight...
