Structure.
Further, the radius of curvature of two top booms of the space of curves tubular truss 11 is identical, forms vertical revolution,
Lower boom is similar to top boom curvature, and connects each chord member by web member 112 and form firm space of curves tubular truss 11；Two
Space of curves tubular truss 11 forms lateral rotation to spatially form the petal-like structures of bi-directional rotary, to the antitorque of structure
It is advantageous with resistance to compression.
Further, the Double-level Reticulated Shell 12 is using the top boom of space of curves tubular truss 11 as exterior chord, space of curves
The lower boom of tubular truss 11 is interior chord member, with 121 phase of web member between the interior chord member, exterior chord on two space of curves tubular truss 11
Even；Specifically, the Double-level Reticulated Shell 12 include interior chord member, exterior chord and connect between chord member, between exterior chord and interior string
Web member 121 between bar and exterior chord.As shown in Fig. 2, exterior chord top is connect with upper ring beam 21, lower part with basis connect, two
Pass through the connection composition outer layer reticulated shell of web member 121, interior chord member top and lower ring between exterior chord on a space of curves tubular truss 11
It is made up of between interior chord member in the connection of beam 22, lower part and basis connection, two space of curves tubular truss 11 connection of web member 121
Internal layer reticulated shell is connected by web member 121 between two layers of reticulated shell, so that being formed has that reasonable stress, structural behaviour is excellent, form is simple
Clean beautiful, economical and practical partial double-layer reticulated shell structure type.
For up-side down triangle space tube truss for stress, two, top chord member is in tension state, the string of lower part one
Bar is in pressured state, and for extent of stability, two, top chord member forms two-dimensional surface system, in addition a string of lower part
Bar forms three-dimensional structure, solves destabilization problems, thus up-side down triangle section form is more reasonable；By between three rod pieces
Connection the power that two, top chord member is subject to is passed into web member, while two web members will be by a petal-like structures unit
Power substructure 4 is passed to by V-arrangement support.Space of curves tubular truss is because itself and basis are in certain angle of cut, power simultaneously
Basis is passed to, the structural stability of single petal-like structures unit is realized.
Further, 1 top of petal-like structures unit is supportted top by 4 connection basis of V-arrangement support and by V-arrangement
Load passes to basis.
Further, as shown in figure 4, the steel construction articulated mounting includes being separately positioned on adjacent petal-like structures list
The pedestal 31 for being provided with elastic rubbery body and movable part 32 in member 1, movable part 32 is by sequentially connected right top plate 321, stainless
Steel plate 322, plane polyfluortetraethylene plate 323, middle steel plate 324 form；Pedestal 31 is benzvalene form fixed bearing face, by spherical surface poly- four
Vinyl fluoride plate 311, rubber seal 312, left roof 313 form；The spherical surface polyfluortetraethylene plate 311 is indent benzvalene form knot
Structure, the middle steel plate 324 are the spirogyrate structure cooperated with indent tub configurations, and the movable part 32 passes through middle steel plate
324 with the spherical surface polyfluortetraethylene plate 311 of pedestal 31 is discontiguous is set together, the spherical surface of middle steel plate 324 and pedestal 31
Elastic rubbery body 33 is provided in gap between polyfluortetraethylene plate 311.Using by semiclosed in the Intrapelvic elasticity of steel
Rubber bodies 33, have the characteristics that under triaxial stress state it is fluidic, to realize the rotation of 32 structure of movable part, due to movable part
32 with left side pedestal 31 is mobilizable links together, similar to the biomimetic features in joint, movable part 32 can be in external force
Under rotated；Use joggle between the plane polyfluortetraethylene plate 323 and middle steel plate 324, the middle steel plate 324 with
The contact of plane polyfluortetraethylene plate 323 side setting is fluted, and plane polyfluortetraethylene plate 323 is embedded in the recessed of middle steel plate 324
To form vertical slide surface in slot；By the stainless steel on the polyfluortetraethylene plate and movable part 32 on middle steel plate 324
The low-friction coefficient that the joggle of plate 322 generates realizes the vertical displacement of right part structure, makes shear stress suffered by pedestal no longer
It is all undertaken by elastic rubbery body, and indirectly-acting is on the slide surface between middle steel plate 324 and polyfluortetraethylene plate 323.
The effect of rubber seal 312 is to prevent dust from invading polytetrafluoroethylene (PTFE) plate surface, influences the sliding capability of support.
Further, the ring beam 2 is the double-deck ring beam, including the upper ring beam 21 and lower ring using triangular shape connection
22, the relatively upper ring beam 21 of lower ring 22 is interior through big.
Specifically, the structural system is made of eight petal-like structures units 1 in a center of symmetry, connection from top to bottom
Mode is successively are as follows: what the double-deck ring beam was taken is triangular shape connection, enhances the intensity between ring beam, the relatively upper ring beam 21 of lower ring 22
Greatly, two ring beams not ensure that the feasibility of power transmission in the same vertical plane.Double-deck ring beam 2 of the petal-like structures unit 1 on
The form for taking consolidation makes total system have enough strength and stabilities.Petal-like structures unit 1 and petal-like structures
- consolidation-is hingedly-consolidation-hinged-consolidation-is hinged-is taken hinged to consolidate the connection type to alternate, make whole knot between unit 1
Structure has self-recovering function.The bottom of petal-like structures unit 1 is connect with basic rigidity, ensure that whole stability.Individually
Petal-like structures unit 1 is made of the Double-level Reticulated Shell 12 of two groups of space tube truss 11 and centre.As shown in figure 3, one group of space
Tubular truss is made of three faces, is made of respectively rod piece interconnection on each face so that each face forms triangle, is made purlin
Frame structural integrity and stability are enhanced.Double-level Reticulated Shell 12 between two groups of truss be by triangle sets at.
It, can at the articulated connection between two pairs of petal-like structures units 1 when overall structure bears additional temperature stress
Appropriateness displacement is generated, energy is absorbed；It is whole at reticulated shell edge and " can breathe " hinged joint under the action of frictional force after unloading
Body structure system return, to realize breathing for structure.In addition, the V-arrangement support that reticulated shell is connected with basis makes total system
Basis is passed to enough rigidity, and by upper load.
The Double-level Reticulated Shell large span of the utility model can breathing structure system as a kind of novel space structure system, tool
There is the features such as rigidity is big, steel using amount is small, easy for construction, economic and environment-friendly performance, enriches the stereoscopic effect of building；Relative to flat
Face truss, the lateral stability and torsional rigidity of space truss are greatly improved, and largely reduce lateral branch
The arrangement of support；The utility model uses the space truss in up-side down triangle section, and for stress, two, top chord member is in
Tension state, the chord member of lower part one is in pressured state, and for extent of stability, two, top chord member forms two-dimensional surface body
System solves destabilization problems in addition a chord member of lower part forms three-dimensional structure, thus up-side down triangle section form is more
Rationally；The power that two, top chord member is subject to is passed into the web member connecting with four fork V-arrangement supports 3 by the connection between three rod pieces,
The power being subject to is supportted 3 by four fork V-arrangements and passes to substructure by two web members in a petal-like structures unit simultaneously.It is bent simultaneously
Power is passed to basis by chord member, realizes single petal-shaped by space of lines tubular truss because itself and basis are in certain angle of cut
The structural stability of structural unit.
