Description
Technical field
Patent of the present invention is related to large-span domes construction applications, and in particular to a kind of traffic circle arrangement rope system support dome
Structure.
Background technology
With continuing to develop for society, demand of the people to public environmental art such as large-scale exhibition center, stadiums etc.
It is growing day by day.This phenomenon has also promoted constantly bringing forth new ideas for large-span space structure form.It is not only in safety, economic aspect
Innovation, it is often more important that the innovation in terms of moulding, meets the aesthetic requirement of people's continuous renewal.In recent years, large span string branch
Using more in the construction of stadium and gymnasium of dome structure, cable dome structure and Cable Truss Structure at home and abroad.
Suspended-dome structure reasonable stress, structural effectiveness is higher, and Path of Force Transfer is clear, takes full advantage of high intensity drag-line
Stress performance, it is ensured that steel using amount is reduced while the rigidity of structure, makes structure become slim and graceful, expressive.Cable dome and rope
Truss structure is all typical Cable Structure, because across spacial ability is strong, the low factor of steel using amount, is also built stadiums etc. are public
It is widely used in building.
However, no matter for suspended-dome structure, or Cable dome or Cable Truss Structure, all exist it is clearly disadvantageous it
Place：
1st, there is obvious key member, i.e. ring rope in suspended-dome structure, once ring rope fails, will cause oblique drawing
The failure of rope and vertical strut, or even directly cause the Progressive Collapse of structure.
2nd, Cable Truss Structure is because structure itself can not ensure Outside-plate stabilizing, it is necessary to circumferentially set steadying line to ensure each
The Outside-plate stabilizing of Pin cable trusses.The collapse resistant capacity of structure is weaker, and radial Cable Truss Structure relies on central strop by each Pin
Cable truss links together, and makes the enough rigidity of structure acquisition and bearing capacity by the central strop of tensioning.Once central strop
Fracture, the rigidity of structure declines substantially, even results in structure and integrally collapses；Meanwhile, levels rod member is all flexible cable, space section
Point coordinates positioning is complicated, and difficulty of construction is larger.
3rd, cable dome structure, once ring rope fails, will cause oblique drawing there is also obvious key member, i.e. ring rope
The failure of rope and vertical strut, or even directly cause the Progressive Collapse of structure；Meanwhile, levels rod member is all flexible cable,
Space nodes coordinate setting is complicated, and difficulty of construction is larger.
The content of the invention
The purpose of patent of the present invention be to improve more than it is not enough there is provided it is a kind of suitable for the buildings such as stadium it is new it is big across
Spend traffic circle rope system supported dome structure.This New Ring-like Type intersects rope system's supported dome structure by top reticulated shell, lower loop
Shape intersects rope system and vertical strut composition.Each drag-line keeps relatively independent in traffic circle rope system, can individually bear lotus
Carry, even if because fortuitous event makes a certain drag-line failure, structure can carry out Internal Force Redistribution immediately, can be by remaining intact rope
System provides bearing capacity, with the common stress of top reticulated shell so that therefore total Collapse will not occur for structure, improve the superfluous of structure
Remaining.
The purpose of the invention is achieved through the following technical solutions：
Traffic circle rope system supported dome structure, it is characterised in that main that rope is intersected by top reticulated shell (1), lower annular
It is (2) and multiple vertical struts (3) composition；It is the ring that multiple drag-line crossed dispersion points are surrounded that lower annular, which intersects rope system (2),
Shape structure；The vertical vertical upper end connection top reticulated shell (1) of strut (3), lower end connection lower annular intersects rope system (2), each perpendicular
It is connected to strut (3) upper end with the grid intersection in top reticulated shell (1), lower end intersects the drag-line of rope system (2) with lower annular
Crossover sites are connected.
Described top reticulated shell, can be Swidler type, lamella type, three according to the difference of mesh generation form
To the grid of grid type, Kai Weite types, rib-ring-shaped, geodesic or other forms；According to the difference of reticulated shell shape, Ke Yishi
Sphere net case or cylindrical latticed shell etc.；Can be single-layer lattice shell, Double-level Reticulated Shell according to the difference of the reticulated shell number of plies；
Described lower annular is intersected rope system (2) and intersected by many relatively independent zips the drag-line cross part of gained
Position is constituted.
It can be one layer, two layers or multi-layer annular structure that described lower annular, which intersects rope system,；Two layers or multilayer loop
Shape structure be located at can up and down different height, be two layers coaxial or multi-layer annular structure；Drag-line crossover sites are using double-deck
Presser type fixture node, the connection of double-deck presser type fixture node and vertical strut is connected using pin.Each drag-line is mutually only
It is vertical, can independent bearing load, even if one because of unexpected failure, Internal Force Redistribution can be carried out immediately, the redundancy of structure is improved.
The drag-line is made up of cable body and anchorage, and cable body uses Galfan coating drag-line or stainless steel cable, cable body two
End is provided with anchorage, using fork ear muff cylinder adjustable type anchorage.
Traffic circle rope system has good with vertical strut in the traffic circle rope system supported dome structure being related in the present invention
Good space-load performance, plays a supportive role to top reticulated shell, changes latticed shell structure force-mechanism, reduces what latticed shell structure was produced
Horizontal thrust.Traffic circle rope system supported dome structure have new in structure, structure stress rationally, progressive collapse-resisting ability
By force, the advantages of architectural image is attractive in appearance, and be easy to make and install, with stronger practical significance.
