Description
Technical field
The utility model is a kind of full tensioning intersection Cable Truss Structure of no inner ring, belongs to a kind of new space structures system,
It is mainly used in space awareness construction applications.Roof arrangement form particularly suitable for large spans such as stadium.
Background technique
With the continuous promotion of china's overall national strength, to meet the ever-growing material and cultural needs of the people, large-scale body
The demand for educating venue is continuously increased.This has been further driven to the development of space structure.How to design safer, economical and suitable
Structural system becomes the striving direction of structure projector.
In the public buildings such as stadiums, Cable Truss Structure is a kind of form of Cable Structure.The arrangement of Cable Truss Structure
Form mainly has parallel arrangement, square crossing arrangement, spoke type arrangement etc..Wherein the shortcoming of spoke type cable truss mainly exists
In there is strop in center, once inner ring fails, structural system is entirely ineffective, even results in structure and integrally collapses.In addition rigidity support
The presence of bar needs to consider the destabilization problems of strut.This structure has abandoned tradition using internal full tensioning " ocean of drag-line and
Strut (compression bar) isolated island " design concept, all realized using drag-line.Meanwhile solving tradition and have inner ring structural system,
The technical problem for causing annular diameters excessive when span is excessive.
Summary of the invention
The purpose of this utility model be anti-Progressive Collapse difference in order to make up existing structure and structure leverage stability not
The problem of foot proposes a kind of to intersect Cable Truss Structure form without the full tensioning of inner ring suitable for stadium.The structure is used by more
The unidirectional self-balanced cabled truss traffic circle arrangement of Pin forms structural system, using the building shape of middle opening, periphery arrangement roofing
Formula.
From cable truss from the point of view of single Pin cable truss by the track cable that winds up, lower edge steadying line, vertical drag-line connection form plane by
The full tensioning cable truss of power；It is formed again by the full tensioning cable truss arranged crosswise of several Pin planes with good space-load performance
Middle opening, periphery arrangement roofing intersect Cable Truss Structure system without the full tensioning of inner ring；Wind up track cable and lower edge steadying line
It is fixed at the upper and lower otic placode of compression fringe truss by bitter end anchorage respectively, provides constraint by compression fringe truss to balance drag-line
In horizontal force.The utility model without the full tensioning of inner ring intersect Cable Truss Structure have full tensioning in vivo, reasonable structural arrangement,
The advantages that structural stability is good, anti-Progressive Collapse is significant, wind resistance is good, architectural image is beautiful, and be easy to make and apply
Work has very strong engineering practice feasibility.
Consider from structural system global analysis, every unidirectional cable truss of Pin can individually bear lotus independently of other Pin cable truss
It carries, therefore even if a certain Pin or a few Pin cable truss, which occur to destroy, exits work, structure residual part can still undertake load, structure hair
The probability of raw entirety Progressive Collapse is smaller.For the sport field structure of middle opening, periphery arrangement roofing, when roofing is using light
Material simultaneously wind load it is very big when, even if total vertical load is upward, winding up for this structural system is symmetrical above and below with lower edge, under
String rope automatically becomes track cable, and structural system can normally undertake the great upward suction under wind action.
The technical solution of the utility model is as follows: a kind of full tensioning of no inner ring intersects Cable Truss Structure, by the track cable that winds up,
The full tensioning cable truss of lower edge steadying line, vertical drag-line connection composition plane stress；Again by the full tensioning cable truss of several Pin planes
Arranged crosswise forms the middle opening with good space-load performance, periphery arrangement roofing intersects cable truss without the full tensioning of inner ring
Frame structural body system；It winds up track cable and lower edge steadying line passes through the upper and lower otic placode that bitter end anchorage is fixed on compression fringe truss respectively
Place provides constraint by compression fringe truss to balance the horizontal force in drag-line.
The track cable that winds up, lower edge steadying line and vertical drag-line in the structural system all use tensional element.
The type of attachment of the vertical drag-line and the track cable that winds up, lower edge steadying line is hinged joint, is only transmitted perpendicular
To the axial tension of drag-line.
This structure is all completed on ground, and the track cable that winds up uses fixed length rope, after ground is completed, is directly mentioned
Design height is risen to, the track cable that winds up is fixed on the upper ear plate of compression fringe truss, successively tensioning lower edge steadying line, and final lower edge is steady
Standing wire is fixed on the lower ear plate of fringe truss, and construction can be completed.
It is that circle is divided into N parts first according to top view, it then can be two of interval M (M≤0.5N) a point on circle
It is in line that point is connected two-by-two, final to realize various forms listed by Fig. 4.Every two point forms a Pin on circle, forms a Pin of structure
Stress unit.Every Pin can be used as a structure, undertake corresponding load, not influenced by other Pin.
Structural advantage: the utility model intersects Cable Truss Structure with full tensioning, structure cloth in vivo without the full tensioning of inner ring
The advantages that reasonable, structural stability is good, anti-Progressive Collapse is significant, wind resistance is good, architectural image is beautiful is set, and is easy to make
Make and construct, there is very strong engineering practice feasibility.This structure all uses rope, can use prestressing force, so that rope be made to begin
It is in the working condition of tension eventually.This structure all uses rope, makes full use of the tensile property of Cable Structure, realizes economical well
Property.

Specific embodiment
A kind of full tensioning intersection Cable Truss Structure of no inner ring, is connected by the track cable 1 that winds up, lower edge steadying line 3, vertical drag-line 2
Connect the full tensioning cable truss of composition plane stress；Being formed again by the full tensioning cable truss arranged crosswise of several Pin planes has good sky
Between the middle opening of stress performance, periphery arrangement roofing intersect Cable Truss Structure system without the full tensioning of inner ring；Wind up track cable
Pass through bitter end anchorage respectively with lower edge steadying line to be fixed at the upper and lower otic placode of compression fringe truss 4, be provided about by compression fringe truss
Beam is to balance the horizontal force in drag-line.
The track cable that winds up, lower edge steadying line and vertical drag-line in the structural system all use tensional element.
The vertical drag-line and wind up track cable, lower edge steadying line type of attachment is hinged joint.
Structural advantage: the utility model intersects Cable Truss Structure with full tensioning, structure cloth in vivo without the full tensioning of inner ring
The advantages that reasonable, structural stability is good, anti-Progressive Collapse is significant, wind resistance is good, architectural image is beautiful is set, and is easy to make
Make and construct, there is very strong engineering practice feasibility.
This structure belongs to the structural system of no inner ring, compared with the structure for having inner ring:
If traditional spoke type Cable Structure is compared, inner ring failure is avoided well, leads to structure total collapse, it is serious to endanger
And the life security of people.
There is inner ring spoke structure for traditional, when structural span is more than 200 meters, the diameter of inner ring can be especially big, existing
Some manufacture crafts are unable to satisfy design requirement.
It can according to need the space structures such as the stadium for designing super-span.
