Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The technology of the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this
Bright, it is not used to limit invention.
As Figure 1-10 shows, rung formula oblique firm string tension structure, including the rigidity outer ring body being arranged at structural edge
It is, is arranged on the flexible cable internal ring system at structure intermediate openings and is arranged on rigidity outer shroud system and flexible cable internal ring
Tension cable and rods system between system and firm beam body system, outside described rigidity outer shroud system is by top rigidity outer shroud 1a and bottom rigidity
Ring 1b forms, and is provided with support rod member 5, in described flexible cable between described top rigidity outer shroud 1a and bottom rigidity outer shroud 1b
Member ring systems is made up of strop 2b in strop 2a in top and bottom, and described firm beam body system is made up of some buckstays 3, described rigidity
The two ends of beam 3 are hinged with strop 2a in bottom rigidity outer shroud 1b and top respectively, and described tension cable and rods system includes some and firm
The drag-line 4a of property beam 3 correspondence, described drag-line 4a two ends are hinged with strop 2b in top rigidity outer shroud 1a and bottom respectively, described in draw
Rope 4a intersects with corresponding buckstay 3, and described drag-line, through corresponding buckstay, is positioned at buckstay 3 times at described drag-line 4a
The side of side, is provided with at least vertical strut 4b between described drag-line 4a and buckstay 3, described vertical strut 4b two ends are divided
The most hinged with drag-line 4a and buckstay 3, it is positioned at the side above buckstay 3, described drag-line 4a and buckstay 3 at described drag-line 4a

Holding hinged with strop 2b in strop 2a in top and bottom respectively, roofing covering material is arranged at firm beam body and fastens.
The Force principle of the present invention and being structurally characterized in that: this structural system has Tension Structure System and rigid structural system concurrently
Feature.By applying pretension in drag-line, make strop, drag-line, buckstay, vertical hanger tension in upper and lower part, upper and lower
Portion's rigidity outer shroud and vertical strut pressurized, total is in the tensioning state of a kind of self-balancing, has the good rigidity of structure.
From overall stress, when structure is by downward load, in buckstay and top, strop internal force reduces, in drag-line and bottom
Strop internal force increases, and resists external load；When structure is by load upwards, in drag-line and bottom, strop internal force reduces, rigidity
In beam and top, strop internal force increases, and resists external load；Increase the rigidity of structure the most further, can in upper and lower part strop
Between arrange inclined member, formed inner band truss.And from local pressure, drag-line passes through vertical strut and vertical hanger bullet
Property buttress brace, reduce buckstay local bending moment.The firm string tension structure that on this, lower edge intersects, under identical span of encorbelmenting
It is substantially reduced the vertical spacing of strop in upper and lower part, reduces the height of vertical strut, while ensureing by force efficiency, effectively
To 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 presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
