Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 Shown is a schematic structural diagram of a horizontal double-ring space scissor unit openable roof based on the idea of ​​the present invention, including scissor unit circles, roof panels, and the like. The scissor unit ring and the roof panel are connected by pins.

[0025] Among them, the scissor unit circle has two circles in total. The scissor unit 2 is formed by pinning two strip plates through the pin shaft 3, forming a middle pin joint node in the middle, and passing the pins at the ends between the scissor units 2. The 3 pins are connected together to form an annular scissor unit ring after unfolding.

[0026] The roof panel is composed of a circle of folding units evenly distributed in the same space, and the folding units are also connected by pin joints. The two folding units at the beginning and the end are opened when unfolding...

Abstract

The invention discloses an openable roof of a space double-ring shear unit. The openable roof of the space double-ring shear unit is composed of shear type unit rings and a roof plate, the number of the shear type unit rings is two, each shear type unit ring is composed of a circle of shear type unit, each shear type unit is formed by the fact that two strip-shaped plates are in pin joint through a pin joint in the middle of the strip-shaped plates, and two adjacent shear type units are in pin joint together at the ends of the strip-shaped plates through pins. The roof plate is composed of sector plates with the same size, and two adjacent sector plates are in pin joint to form a folding unit. Two adjacent sector plates form a crest line and a valley line on the boundary of space inner roofs. One circle of shear type unit rings are arranged on the crest line, the other circle of shear type unit rings are arranged on the valley line, and the two circles of shear type unit rings are placed at the positions in different radii from the center of the circle of the roof plate. According to the roof structure, annular opening and closing of a roof system are achieved through opening and closing of the shear type unit rings, the structure is reasonable, design and construction are simple, and the openable roof is particularly suitable for small and medium span buildings.

Description

technical field [0001] The invention relates to an openable roof structure, in particular to a space double ring scissor unit openable 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 ...
