Embodiment
A kind of large span as shown in Figure 1 can breathing structure system, including reticulated shell 1 and 6 lattice columns 2.Lattice column 2 is set respectively
Put five angles at the center of reticulated shell 1 and reticulated shell 1；Three angle endpoint nodes are discoid node in five angles.
As shown in Figure 1, 2, reticulated shell 1 is the Double-level Reticulated Shell that is made up of multiple six shapes frame units 11, upper and lower two layers of hexagon
Connected between frame unit 11 by elastic short column 12, between upper and lower two layers of hexagonal-shaped frame unit 11 and single hexagonal-shaped frame
There is the drawing connection of carbon fiber 13 between the drift angle of unit 11 and frame.Two layer of space latticed shell structure imitates elytrum internal structure.Reticulated shell 1 is logical
Endpoint node is crossed with lattice column 2 to be connected.The reticulated shell 1 of the structure can produce certain deformation, and it is uneven to reduce wind load, bearing
Difference influence to caused by building is responded in even sedimentation and seismic wave transmittance process, while when there is the larger temperature difference, warp can breathe
The controllable displacement of node, release or consumption temperature stress, make roof system to be breathed in two dimensional surface.The elastic structure of short column 12 copies sheath
It is used for connecting the back of the body, the hollow pillar of the fiber of stomach wall in wing, this structure can realize breathing for structure longitudinal direction, effectively mitigate whole
Body is conducted oneself with dignity, and realizes energy consumption effect, while the composite knitting structure of the fiber interlayer of imitative elytrum is advantageous to improve the strong of structure
Spend and improve toughness, structure is fully resisted the effect of various loads.
As shown in Figure 3,4, lattice column 2 includes cylinder 21, and a triangle platform is done in the upper surface of cylinder 21 of lattice column
22, and tri-angle-holed 24 are opened on triangle platform 22.Tri-angle-holed 24 inscribed circle diameter is more than the discoid section of reticulated shell end
The diameter of point 23（The discoid diameter of node 23 is with tri-angle-holed 24 inscribed circle diameter difference by local day and night temperature, Seasonal Temperature Difference
And the actual decision of rod member）, so that reticulated shell end disc shape node 23 can occur in all directions in tri-angle-holed 24
A range of relative displacement.Require that hole wall can bear the shear action of reticulated shell end simultaneously, set on the outside of hole wall a plurality of
Ribbed stiffener 25.The combination of nodes can transmit vertical load, and can be by controlling disk nodular point 23 and triangle platform 22
The frictional force come between control node steel plate of relative pressure so that the combination of nodes can undertake normal dead load, mobile load and
Wind load and temperature change are not more than critical value（Set according to actual conditions）The caused lower rod member of temperature stress combination
Axle power.When producing temperature deformation, because the frictional force between steel plate is overcome, node can produce controllable in tri-angle-holed 24
Displacement, structure is undertaken vertical load and horizontal loading well, while but also with good release temperature stress
Ability.
When total bears additional temperature stress, two layer of space latticed shell structure and the connection place of reticulated shell and lattice column
Micro-displacement can be produced, absorbs energy；After unloading, the frictional force at the hollow short column of reticulated shell high resiliency and " can breathe " node
Under effect, total system return, so as to realize breathing for structure.In addition, reticulated shell make with the lattice column that is connected of basis it is whole
Individual structural system has enough rigidity, and upper load is passed into basis.
