Abstract
The invention discloses a radial retractable net rack structure which is composed of two or more annular chained shear mechanisms and two or more radial chained shear mechanisms. The annular chained shear mechanisms are arranged in a concentric mode, and the radial chained shear mechanisms are arranged in the radial direction of circular rings formed by the annular chained shear mechanisms. Each annular chained shear mechanism is in an annular shape formed by connecting a plurality of annular symmetrical shear hinge units in an end-to-end mode. Each radial hinged shear mechanism is in a linear shape formed by connecting a plurality of radial symmetrical shear hinge units in an end-to-end mode. Each radial chained shear mechanism and the corresponding annular chained shear mechanism are connected in the mode that the ends of second connection rods of the radial symmetrical shear hinge units and the ends of first connection rods of the annular symmetrical shear hinge units are hinged. The net rack structure can extend and retract freely, and the ratio of extension and retraction is large; the folding directions of the radial shear hinge units and the annular shear hinge units are both in a vertical plane, so that the net rack structure has high vertical stiffness; and besides, the radial retractable net rack structure is reasonable, easy to design and construct and particularly suitable for buildings with medium and small spans.
Description
Technical field
The present invention relates to a kind of grid structure, especially a kind of have the radially radial expansion with ring chain scissor mechanism
Grid structure.
Background technology
Deployable structure is a kind of new structure growing up nearly over half a century, in aerospace, building structure and military work
The fields such as journey play an important role.Being mainly characterized by of deployable structure has two kinds of stable configurations：Completely folded state and complete
Entirely organize work state.In folded state, structure is drawn in a certain given shape, in the presence of extraneous driving force, structure
Progressively launch, reach fully deployed working condition, be then locked as steady statue.
It is a kind of space structure cutting with scissors unit based on scissors that the hinged structure of scissors can be opened up, and can design colourful geometry
Profile.This structure becomes close bundle shape after folding completely, reach original operating state, can cover after being sufficiently spread out fixing
Larger space.Total can be produced by batch in factory simultaneously, fold bundled shape and transport building site and launch after completing
Use；Additionally, this class formation is extremely easy to remove.Using this feature, this structure can be widely applied to military architecture, short-term
Property building, in the large-span space structure such as stadium and grand theater.
At present deployable structure has that size span is little, and thick stick number of packages amount is many, the complicated problem of joint structure, and the rigidity of structure
Poor, stable problem projects, and is unfavorable for designing and constructs.
Content of the invention
The technical problem to be solved is the deficiency existing for above-mentioned prior art, and provides one kind vertically firm
Spend, shrinkage factor is big and structure is simply easy to the radial telescopic net structure that folds.
For solving above-mentioned technical problem, the technical solution used in the present invention is：
A kind of radial telescopic net structure is it is characterised in that by plural ring chain scissor mechanism and plural
Radial direction chain scissor mechanism forms, described ring chain scissor mechanism arranged concentric, and described radial direction chain scissor mechanism is along described
The radial arrangement of the annulus that ring chain scissor mechanism is formed；Described ring chain scissor mechanism is cut with scissors by the symmetrical scissors of multiple rings
Unit is connected to annular end to end, and the symmetrical scissors of described ring cut with scissors the folding direction vertically described annulus place plane of unit, each
The symmetrical scissors of ring are cut with scissors the first connecting rod by two equal lengths for the unit and are formed the middle part of first connecting rod is hinged, adjacent two rings
Hinged in the end of first connecting rod between the first connecting rod of symmetrical scissors hinge unit；Described radial direction chain scissor mechanism is by multiple footpaths
It is connected to linear end to end to symmetrical scissors hinge unit, each radial symmetric scissors cuts with scissors the second connecting rod by two equal lengths for the unit
Form the middle part of second connecting rod is hinged, adjacent two radial symmetric scissors are cut with scissors between the second connecting rod of units at the end of second connecting rod
Portion is hinged；Described radial direction chain scissor mechanism cuts with scissors unit with described ring chain scissor mechanism by described radial symmetric scissors
The hinged realization in first connecting rod end that second connecting rod end scissors symmetrical with described ring cut with scissors unit is connected.
Described radial direction chain scissor mechanism is evenly arranged on described annulus, and described ring chain scissor mechanism is in annulus
Radially equidistant placement.
The number of described ring chain scissor mechanism is 3～10, the number of described radial direction chain scissor mechanism is 10～
40.
Described first connecting rod is straight-bar.
Described first connecting rod is plane straight-bar.
Described second connecting rod is straight-bar.
Described second connecting rod is plane straight-bar.
When grid structure is in closure state, footpath ring chain scissor mechanism shrinks bundled shape, is readily transported；Work as rack
When structure is launched, radially with ring chain scissor mechanism synchronous extension, until fully deployed, after locking, become steady statue.
Beneficial effect：The present invention realizes the folding of grid structure by footpath ring chain scissor mechanism synchronization telescope, so that
Obtain grid structure and stretch freely, expansion and contraction is big, and it constructs reasonable, design and construction is simple, the Foldable square of scissors hinge unit
To for vertical plane, make grid structure have larger vertical rigidity, be particularly suitable for the building of medium and small span.

Specific embodiment
Referring to Figure of description, more detailed description is made to the present invention：
As shown in figure 1, a kind of radial telescopic net structure 1.Radial expansion latticed shell structure 1 is by 3 ring chain scissor mechanism 2
Form with 16 radial direction chain scissor mechanism 4.Wherein, ring chain scissor mechanism 2 cuts with scissors 3 groups of unit by the symmetrical scissors of 48 rings
Become, the radially even arranged for interval of ring chain scissor mechanism 2；Radial direction chain scissor mechanism 4 is cut with scissors by 12 radial symmetric scissors
Unit 5 forms, radial direction chain scissor mechanism 4 circumferentially uniform intervals arrangement.
As shown in Fig. 2 ring chain scissor mechanism is connected into ring by 48 rings symmetrical scissors hinge unit header WEILIAN, adjacent two
Hinged in the end of first connecting rod between scissors hinge unit；
As shown in figure 3, radial direction chain scissor mechanism cuts with scissors unit by 12 radial symmetric scissors being formed by connecting, adjacent two scissors hinges are single
Hinged in the end of second connecting rod between unit；
As shown in figure 4, the connecting node composition of footpath ring chain scissor mechanism is as follows：Ring chain mechanism 2 and radial direction chain machine
Structure 4 cuts with scissors unit first connecting rod by the symmetrical scissors of ring and radial symmetric scissors are cut with scissors unit second connecting rod end hinged joint 6 and connected.
Thus, by the effect of this hinged joint, radial direction chain scissor mechanism and ring chain scissors in grid structure moving process are realized
The synchronization telescope of mechanism.
The symmetrical scissors hinge unit of composition ring as shown in Figure 5 and radial direction chain scissor mechanism is that current application is the widest
