Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like figure 1 Shown is a schematic structural view of a circularly expanded roof based on the idea of ​​the present invention, including columns 5, scissor unit rings, roof panels, and the like. The scissor unit ring and the roof panel are connected by pins.

[0028] Among them, the scissor unit circle has only one circle, and the scissor unit 2 is formed by pinning two strip plates through pins 3, forming a middle pin joint node in the middle, and between the scissor units 2 at the ends respectively through pins 3 Pinned together and unfolded to form an annular scissor cell ring.

[0029] The roof panel is composed of a circle of folding units evenly distributed on the same circle, and the folding units are also connected by pin joints. The two folding units at the beginning and the end are opened when they are unfolded or folded. See figure 2 . Each foldi...

Abstract

The invention discloses an annularly unfolded roof structure. The annularly unfolded roof structure is composed of a column, a shear unit ring and a roof panel. The shear unit ring is composed of a circle of shear units. Two strip-shaped plates are pin-joint through middle pin joints in the middles of the strip-shaped plates to form each shear unit. Every two adjacent shear units are pin-joint together through pins at the ends of the strip-shaped plates. The roof panel is composed of a circle of folding units which are evenly distributed on the same circle, and two fan-shaped plates are pin-joint on the side faces to form each folding unit. The inner end of each folding unit is arranged on the column, the upper end of each folding unit is provided with one shear unit for driving the folding unit, and the shear unit ring is located in the roof panel. According to the roof structure, through unfolding and folding of the shear unit ring, the roof system can be annularly unfolded and folded, and the annularly unfolded roof structure is reasonable in structure, easy to design and construct and particularly suitable for small-space and medium-span buildings.

Description

technical field [0001] The invention relates to an openable roof structure, in particular to an annular unfolded roof structure. Background technique [0002] The deployable structure is a new type of structure developed in the past half a century, and it plays an important role in the fields of aerospace, building structure and military engineering. The main feature of a deployable structure is that it has two stable configurations: a fully folded state and a fully unfolded working state. In the folded state, the structure is gathered in a certain shape, and under the action of external driving force, the structure is gradually unfolded, reaching the fully unfolded working state, and then locked into a stable state. [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 folded, and reaches the initial working state after be...
