Description
Technical field
The present invention relates to a kind of foldable cylinder membrane structure, particularly a kind of foldable cylinder film knot with rigid bracing
Structure.
Background technology
Foldable structure top meets Contemporary Architecture theory, is a Main Trends of The Development of large span spatial structure, it is increasingly
Favored by people.Foldable structure because its have the advantages that short time limit, easily resettlement and it is repeatable utilize, having caused the modern times builds
The great interest for teacher of the building.But, using less in large-span structure, main cause has for it：（1）The design of node of folding grid structure
It is typically complex, still lacks simple structure and practicality, the design of node of cheap suitable engineer applied at present；（2）Folding
The component of folded network is except in addition to by axle power, also by certain moment of flexure, stress performance is bad, and cost is higher；（3）Folding grid structure
Rigidity it is very poor, displacement is more difficult to meet requirement.
Only foldable cylindrical reticulated shell and then can the rigidity of structure deficiency, according to planar film, then can not provide from geometry
The rigidity of shape, and planar film is also easy to that fold and tear occurs, and had not only influenceed attractive in appearance but also had influenceed to use, space membrane is effectively kept away
These shortcomings of planar film are exempted from.
The content of the invention
The present invention to be solved technical problem is to be directed to above-mentioned the shortcomings of the prior art, and it is simple to provide a kind of structure
Single, easy for construction, cost is low and the foldable cylinder membrane structure of good stress performance, can preferably meet that temporary building is conveniently built
With requirement of the mobile and long span building to folder function, it can more meet the rigidity requirement of membrane structure.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of foldable cylinder membrane structure with rigid bracing, including latticed shell structure and it is arranged on the latticed shell structure
On membrane structure, the latticed shell structure by more Pin fold arch unit connect and compose, it is characterised in that：It is described that arch unit is folded per Pin
Be connected to form by n rectangular pyramid elementary cell along structural span direction, n be >=2 natural number, the rectangular pyramid elementary cell
It is made up of four positive pole scissors units, the positive pole scissors unit is made up of two poles, and the positive pole is cut
The angle of upper end is more than the angle of lower end between two poles of formula unit, and four positive pole scissors units pass through from beginning to end successively
Endpoint node connects circlewise, and the intermediate node of four pole scissors units is generally aligned in the same plane interior, adjacent two Pin foldings arch list
Connected between member using reverse folded scissors unit, the reversely pole scissors unit is also made up of two poles, described reverse
The angle of upper end is less than the angle of lower end, the endpoint node of reverse folded scissors unit between two poles of pole scissors unit
It is connected on the endpoint node that arch unit is folded per Pin along the forward folded scissors unit on structure length direction；The film
Structure is made up of a folding film unit on each rectangular pyramid unit, the folding film unit include four support bars with
And the membrane material on the support bar is attached to, four post uppers are hinged, and the lower end of every support bar is hinged on four ribs
In four ring connecting nodes for boring unit, the membrane material top is fixed on the point of intersection of four support bars, the membrane material lower part
It is not fixed in four ring connecting nodes of rectangular pyramid unit.
Equal length of the pole in intermediate node both sides.
The pole is the rod member of plane link or space structure.
Described strut is straight-bar and identical length is same.
Described stay length should be greater than the length of pole intermediate node side.
The mechanism of the present invention is single-degree-of-freedom system, reduces the quantity of drive device；Further, since what the present invention was formed
Number of components gives a kind of effect of brevity and lucidity of people far fewer than in general folding grid structure, overcomes network sense
See the shortcomings that upper lever is various in disorder；And by having the folding membrane structure dead load of ring support bar lighter thereon,
Folding is flexible, adds the rigidity of structure, structure simple structure, designs and easy for construction, be particularly suitable for the building of medium and small span.

Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the elementary cell of the present invention is pole scissors unit 1.Each pole scissors unit 1 is by two poles
2 compositions, bending place connect in the midpoint of pole 2, two poles 2 of pole scissors unit 1 in bending place pin joint, and dotted line is folding exhibition
The movement locus of pole scissors unit in open procedure.
Four folding and expanding direction of motion identical pole scissors units 1 are connected to form a foldable expansion by ring
Rectangular pyramid unit 3, as shown in Figure 9.Any one pole scissors unit 1 of anchor portion, is formed single-degree-of-freedom system, can
Realize overall expansion and fold.Determine after structural span for avoid the incompatible pole size of geometry all by do boost line come it is true
It is fixed.One rectangular pyramid unit 3 is regarded as with a pole scissors unit 1 as object, the folding and expanding of pole scissors unit 1 fortune
Put what annular array was formed centered on dynamic center, a folding film unit 4 is set on each rectangular pyramid unit 3.Folding film unit 4
It is made up of four support bars 41 for meeting at any on top with adhering to superincumbent membrane material 42, ring of the support bar 41 along rack
Arrangement, lower end ring node corresponding with rectangular pyramid unit 3 are connected, and the top of membrane material 42 is fixed on the intersection point of four support bars 41
Place, the bottom of membrane material 42 is separately fixed on four nodes of rectangular pyramid unit 3.
Shape is similar between folding film unit 4, and composition component is identical each other, the company of seamlessly transitting between folding film unit
Connect.N such rectangular pyramid units 3 join end to end, and being directed around half of circumference along span forms Pin folding arch units 5 as schemed
Shown in 6.Wherein n is natural number n >=2.The pin-connected joints of any one pole scissors unit 1 of end are connected with substructure,
Single-degree-of-freedom system is formed, overall expansion can be achieved and fold.Using it is any fold encircle unit interior joint fringe node as
Stationary nodes are connected with bearing, then system is a single-degree-of-freedom system, so as to reach the purpose for reducing drive device quantity.
Positive pole scissors unit 1 is connected signal with a reverse pole scissors unit 1 as shown in fig. 7, along structure length
Direction, adjacent pole scissors unit motion are in opposite direction.Pass through per Pin between folding arch unit（n+1）It is individual to be rolled over substantially with folding in arch
Bar scissors unit motion pole scissors unit in opposite direction is connected, be formed foldable cylinder membrane structure 6 as shown in figure 8,
Whole system can realize that single-degree-of-freedom folding and expanding moves.
As shown in Figure 2,3, during foldable cylinder membrane structure expansion, membrane material 42 is in tensioning state, bears extraneous and structure
The load of itself, rigidity is provided for structure, distance is maximum between the intersection point of four support bars 41；As shown in Figure 4,5, when foldable post
When facial mask is packed up, the distance of the distance between four support bars 41 rack plane also reduces therewith, and membrane material 42 is in relaxed state.
