Embodiment Construction

[0021] Below with reference to accompanying drawing of description, the present invention is described in more detail:

[0022] Such as figure 1 As shown, a flat radially retractable roof structure 1 is shown. The plane 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 circular symmetrical scissor hinge units 3, and the circular chain scissor mechanism 2 is evenly spaced along the radial direction; the radial chain scissor mechanism 4 is composed of 14 diameter Composed of symmetrical scissor hinge units 5, the radial chain scissor mechanism 4 is evenly spaced along the ring direction. And the radial chain-shaped scissor mechanism 4 stretches out from the outermost ring to a certain length of the chain-shaped scissor mechanism, and is fixed on the hinge support 7 with only vertical rotation freedom.

Abstract

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 radial openable roof structure, in particular to a plane openable roof structure with a radial chain scissor mechanism. Background technique [0002] The retractable 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 change of the atmosphere and the use requirements of the building. The main feature of the retractable roof structure is that it has two stable configurations: a fully closed state and a fully unfolded working state. The roof needs to move and have multiple different stress states during normal use. Compared with conventional building structures, the design and construction are more complicated. [0003] The deployable scissor hinge structure is a space structure based on the scissor hinge unit, which can design a variety of geometric shapes. This structure becomes a tight bundle after being fully folde...
