In, in described top, in strop 2a and bottom, between strop 2b, it is provided with diagonal web member forms hoop truss 6, described diagonal web member two
Holding hinged with strop 2b in strop 2a in top and bottom respectively, roofing covering material is arranged at firm beam body and fastens.
Force principle of the present utility model and being structurally characterized in that: this structural system has Tension Structure System and rigid structure concurrently
The feature of system.By applying pretension in drag-line, make strop, drag-line, buckstay, vertical hanger tension in upper and lower part,
Upper and lower part rigidity outer shroud and vertical strut pressurized, total is in the tensioning state of a kind of self-balancing, has good structure
Rigidity.From overall stress, when structure is by downward load, in buckstay and top, strop internal force reduces, drag-line and
In bottom, strop internal force increases, and resists external load;When structure is by load upwards, in drag-line and bottom, strop internal force subtracts
Little, in buckstay and top, strop internal force increases, and resists external load;Increase the rigidity of structure the most further, can be in upper and lower part
Arrange inclined member between interior strop, form inner band truss.And from local pressure, drag-line passes through vertical strut with vertical
Hoist cable resilient support buckstay, reduces the local bending moment of buckstay.The firm string tension structure that on this, lower edge intersects, encorbelments identical
It is substantially reduced the vertical spacing of strop in upper and lower part under span, reduces the height of vertical strut, ensure same by force efficiency
Time, effectively solve traditional vehicle spoke tension structure strut higher, affect the defect in space in field.
As shown in figure 11, described some buckstays 3 and some drag-line 4a are spoke along flexible cable internal ring system periphery respectively
Formula of penetrating is arranged and corresponding matching;Or, as shown in figure 12, described some buckstays 3 and some drag-line 4a are respectively along flexible cable
Internal ring system periphery is that trigonometric expression is arranged and corresponding matching;Or, as shown in figure 13, described some buckstays 3 and some drag-lines
4a is that staggered form is arranged and corresponding matching respectively along flexible cable internal ring system periphery.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
