Development, in recent years, there has been proposed to span more than more than 200m very large span spatial strcture demands.
Patent CN101906815A provides a kind of suspended support arch shell structure, by having reticulated shell on radial direction pull bar, while
The bottom of radial direction pull bar is provided with ring drag-line, collectively forms a kind of suspended lattice shell structure, although this structure can overcome individual layer
The shortcomings that reticulated shell or the Double-level Reticulated Shell stability difference of thinner thickness, but the end points of radial direction pull bar all in the patent converges in
Encircle the summit of shell, support is formed to the top of structure jointly so that the top of structure is point stress, and this force way is not steady enough
It is fixed, integrally-built collapse easily occurs when top pressure is big.
Utility model content
The purpose of this utility model is to provide a kind of iterative structure of super-span regarding to the issue above.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of iterative structure of super-span, the iterative structure of the super-span include Huge Steel Truss structure and overlapping
In the suspended lattice shell structure of Huge Steel Truss superstructure, the main framing of the Huge Steel Truss structure includes ring truss and footpath
To truss, the radial direction truss is located at ring truss bottom and is connected with ring truss, ring of the common support positioned at center of top
To truss, the suspended lattice shell structure is superimposed on the top of ring truss, and support frame is not provided between the radial direction truss.
The Huge Steel Truss structure also includes single-layer lattice shell, and the single-layer lattice shell is between adjacent radial direction truss.
The single-layer lattice shell includes ring beam and bearing diagonal, the interlaced composition single-layer lattice shell of ring beam and bearing diagonal, divides
It is distributed between adjacent radial direction truss.
The sectional area of the top boom of the ring truss is not less than 49000mm2, the sectional area of lower boom is not less than
41233mm2。
The main framing of the suspended lattice shell structure includes ring dome drag-line and radial direction strut, and the radial direction strut is circumferentially
Dome drag-line supports ring dome drag-line, and is connected with ring truss.
The single-layer lattice shell to match with the ring truss is additionally provided between the ring dome drag-line and radial direction strut.
Compared with prior art, the utility model has the advantages that：
(1) iterative structure entreats ratio in the structure by the way that Huge Steel Truss structure is mixed into application with suspended lattice shell structure
More flat region uses suspended-dome structure, and formalness acts on stronger position and uses the huge of " main framing+secondary structure "
Steel truss structure, structure function effect can be given full play to using the combined structure system of innovation, make most of component of structure
For uniaxial force component, on the premise of structure safety is ensured, structural material dosage is reduced to greatest extent；Huge steel truss simultaneously
The main framing of frame includes ring truss and radial direction truss, i.e. the force way at top is overall for the ring structure that ring truss is formed
Stress is more stable compared with traditional point force way, structure.
(2) time structure, this structure one are used as using by the single layer mesh that ring beam and bearing diagonal are formed in Huge Steel Truss
Aspect can independently undertake the vertical load and horizontal loading in the range of self zone, on the other hand can be that radial direction truss carries again
For stronger lateral support, so as to improve the resistance to overturning of structure and torsional rigidity, improve internal force distribution.
(3) sectional area of the top boom of ring truss is not less than 49000mm2, the sectional area of lower boom is not less than
41233mm2, because ring truss is to be in center of top, it is pressurized huge, thus top boom and the larger sectional area of lower boom can
To improve the rigidity of ring truss and bearing capacity, vertical load can be individually set up and can bear so as to be together constituted with radial direction truss
Main framing, the stability of reinforcement structure.
(4) main framing of suspended lattice shell structure includes ring dome drag-line and radial direction strut, i.e. suspended lattice shell structure is also
Face stress and non-dots stress, the local pressure at top is further alleviated, improve the stability of structure.
(5) single-layer lattice shell to match with ring truss is additionally provided between ring dome drag-line and radial direction strut, further
The support strength of suspended lattice shell structure is improved, enhances the stability of structure.
