Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of full tension cord bar structural system of roof of flexible boundary.
Technical scheme: for solving the problems of the technologies described above, a kind of full tension cord bar structural system of roof that the utility model provides comprises: Levy type rope dome and annular stretching integral, and described annular stretching integral is connected in the edge of Levy type rope dome; Described Levy type rope dome comprises depression bar in 1 center depression bar, the interior depression bar of n root and n root, and notochord, upper radial cable, lower radial cable, interior strop, middle strop, upper oblique cord and lower oblique cord, wherein interior depression bar and middle depression bar are arranged in respectively and take the center depression bar on two concentric circles in the center of circle, the two ends of described center depression bar and the top of interior depression bar are connected with respectively notochord and upper radial cable, the two ends of described interior depression bar and middle depression bar top are connected with respectively notochord and lower radial cable, the bottom of described interior depression bar is connected with interior strop, and the bottom of described middle depression bar is connected with middle strop; Described annular stretching integral comprises the outer depression bar of staggered n group, every group of outer depression bar comprises 4 outer depression bars that are linked in sequence, two outer depression bars in every middle depression bar and every group of outer depression bar are connected to a common points, one end of the two ends of every middle depression bar and adjacent one group of outer depression bar is connected with respectively oblique cord and lower oblique cord, between the outer depression bar of adjacent sets, be connected with stretching rope, wherein middle strop and lower oblique cord are the shared rope of Levy type rope dome and annular stretching integral.
As preferably, for the ease of connecting common points when the construction, described common points is ball pivot, and described ball pivot comprises spherical heart section and is articulated in three rotating connecting portions in heart section.
Beneficial effect: the utility model is combined Levy type rope dome together with annular stretching integral innovatively, and the beneficial effect had is:
1) Levy type rope dome depends on the flexible boundary of annular stretching integral, and two kinds of structures form the structural system of self-balancing, has given full play to the advantage of two kinds of structural systems;
2) in conjunction with after system in all Suo Shoula, the bar pressurized, saved steel to the full extent, light high-efficiency has been given full play to the intensity of material, has promoted the service efficiency of material;
3) all members of this structural system are all first to be prefabricated in the factory, and have greatly improved the reliability of member.Field operation is all assembling construction and pre-stress construction, has farthest reduced the impact of work progress on environment, has reduced labour intensity and the difficulty of field worker, has shortened construction period, has also reduced construction cost simultaneously.
