Example Embodiment

[0022] Hereinafter, the present invention will be described in more detail with reference to the drawings in the specification:

[0023] Such as figure 1 Shown, a radial telescopic grid structure 1. The radial telescopic reticulated shell structure 1 is composed of 3 circular chain scissor mechanisms 2 and 16 radial double-layer chain scissor mechanisms 4. Among them, the circular chain scissor mechanism 2 consists of 48 circularly symmetric scissor hinge units 3, and the circular chain scissor mechanism 2 is arranged at even intervals in the radial direction; the radial double-layer chain scissor mechanism 4 consists of upper and lower The aligned two-layer chain-shaped scissor mechanism consists of 12 radially symmetric scissor hinge units 5 in each layer of chain-shaped scissor mechanism, and the radial double-layer chain scissor mechanism 4 is evenly spaced in the circumferential direction.

[0024] Such as figure 2 As shown, the circular chain-shaped scissor mechanism consis...

Abstract

The invention discloses a radial dual-layer flexible grid structure which comprises more than two loop chain-shaped shear mechanisms and more than two radial dual-layer chain-shaped shear mechanisms, wherein the loop chain-shaped shear mechanisms are concentrically distributed; the radial dual-layer chain-shaped shear mechanisms are distributed along the radial direction of the loop formed by the loop chain-shaped shear mechanism; each loop chain-shaped shear mechanism is formed by a plurality of loop symmetric scissor-like units which are connected end to end to form a loop; each radial dual-layer chain-shaped shear mechanism comprises upper and lower horizontal shear mechanisms which are aligned, and each shear mechanism layer is formed by a plurality of radial symmetric scissor-like units end to end to form a line; and upper and lower radial chain-shaped shear mechanism layers are respectively connected with the loop chain-shaped shear mechanisms through a second connecting rod end part of the radial symmetric scissor-like units and a first connecting rod end part of the loop symmetric scissor-like units. The grid structure can be expanded and contracted freely, has a high rate of expansion and contraction, has a reasonable structure and simple design and construction, and is especially suitable for buildings with medium and small spans.

Description

technical field [0001] The invention relates to a grid structure, in particular to a radially stretchable grid structure with a radial double-layer chain-shaped scissor mechanism and a circular chain-shaped scissor mechanism. Background technique [0002] Deployable structure is a new type of structure developed in the past half century, which 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 becom...
