The specific embodiment
Radially open-type cable dome structure of the present invention, as shown in Figure 1, comprise: side ring beam 1, notochord 2, strop 3, innermost circle strut 41, jury strut 42, radial cable 5, upper center tension ring rope 61, lower center tension ring rope 62 and initiatively rope 7, described side ring beam 1 is by the n root beam positive n limit shape ring beam forming that joins end to end, n is not less than 4 and be not more than 720, described Shang center tension ring rope 61 is upper ends of being passed through successively innermost circle strut 41 by a drag-line, and form a ring, first steel pipe 8 of every section of drag-line overcoat of Shang center tension ring rope 61, its length is the distance between innermost circle strut, outside total n root the first steel pipe 8 of upper center tension ring rope 61, as shown in Figure 2.
Described Xia center tension ring rope 62 is lower ends of being passed through successively innermost circle strut 41 by a drag-line, and form a ring, first steel pipe 8 of every section of drag-line overcoat of Xia center tension ring rope 62, its length is the distance between innermost circle strut,, outside total n root the first steel pipes 8 of lower center tension ring rope 62.
One end of notochord 2 is anchored on side ring beam 1, the other end Yu Shang center tension ring rope 61 of notochord 2 connects, notochord 2 is radial to arc lower, be connected and form by multistage drag-line, the turning point of the upper end of jury strut 42 and notochord 2 is hinged, one end of the lower end of jury strut 42 and outmost turns radial cable 5 and strop 3 are hinged, the other end of outmost turns radial cable 5 is also anchored on side ring beam 1, the turning point of one end of innermost circle radial cable 5 and notochord 2 is hinged, the lower end of the other end of innermost circle radial cable 5 and innermost circle strut 41 is hinged, initiatively one end of rope 7 is connected to the middle part of innermost circle strut 41, the other end is anchored on side ring beam 1 contact.
Described strop 3 is along hoop closed arrangement, each ring is the end that a drag-line passes jury strut 42 successively, the length of overlapping second steel pipe 9, the second steel pipes 9 on the every section of strop 3 between jury strut 42 is the distance between jury strut 42, as shown in Figure 3.
Described Shang center tension ring rope 61 absolute altitudes are the highest, strut top absolute altitude hoop is identical, radially successively decrease from inside to outside, tension ring Suo61He Xia center, described Shang center tension ring rope 62, notochord 2, strop 3, radial cable 5 is prestressed cable, described strut can be metal rod or metal tube, described side ring beam 1 is pressurized side ring beam, generally can use reinforced concrete beam, rigidity is large, Compressive Performance is good, construction is also convenient, radial cable 5, the steel plate that initiatively anchoring of rope 7 and notochord 2 is used can be embedded on this beam, tension operation space spaciousness, easy to operate, all prestressed cables can adopt high tensile steel wire, steel strand or wire rope,
Radially open-type cable dome structure opening process is: loosen the constraint of upper center tension ring Suo61He Xia center tension ring rope 62 and every strop 3, the prestressing force of cable dome structure is removed, also be that cable dome structure changes mechanism into, shrink initiatively rope 7 to side ring Liang1Chu, along with the continuous contraction of active rope 7, the length of strop constantly increases, the coverage of structure constantly reduces, the scope that central authorities do not have rope dome to cover is increasing, until initiatively the length of rope 7 is reduced to minimum, the opening process of structure finishes, structural configuration in opening process as shown in Figure 4, the first steel pipe 8 in motion process as shown in Figure 5.
Radially open-type cable dome structure closing course is: loosen the initiatively constraint of rope 7, constantly tension ring Suo61He Xia center, center tension ring rope 62 and strop 3 in stretch-draw, the length of upper center tension ring Suo61He Xia center tension ring rope 62 and strop 3 reduces, thereby all rod members are constantly moved to middle part, until equaling the length of the first steel pipe 8 and the length of every section of strop 3, the length of tension ring Suo61He Xia center, Mei Duanshang center tension ring rope 62 equals the length of the second steel pipe 9, continue tension ring Suo61He Xia center, center tension ring rope 62 and strop 3 in stretch-draw, make to produce in rod member prestressing force, thereby make mechanism become structure.
For conventional cable dome structure, its prestress distribution can be tried to achieve by balancing matrix theory, and Shang of the present invention center tension ring Suo61He Xia center tension ring rope 62 and strop 3 outer surface covers a steel pipe, its prestressing force mode change, its calculate schematic diagram as shown in Figure 6.
t 1for cable dome structure itself is given the pulling force of upper center tension ring Suo61Huo Xia center tension ring rope 62 or strop 3 from stress mode;
t 2for with steel pipe in pressure
cthe Suo Lali of balance, thus radially on open-type cable dome structure the prestressing force of tension ring Suo61Huo Xia center, center tension ring rope 62 or strop 3 be
t 1+
t 2.
