The specific embodiment
The radially open-type cable dome structure of the utility model; As shown in Figure 1; Comprise: side ring beam 1, notochord 2, strop 3, inner ring strut 41, jury strut 42, radially rope 5, go up center pulling force strop 61, center pulling force strop 62 and rope 7 initiatively down, the positive n limit shape ring beam that described side ring beam 1 is joined end to end and formed by n root beam, n are not less than 4 and be not more than 720; The described center pulling force strop 61 of going up is upper ends of being passed through inner ring strut 41 by a drag-line successively; And form a ring, and one first steel pipe 8 of every section drag-line overcoat of pulling force strop 61 at last center, its length is the distance between the inner ring strut; Last center pulling force strop 61 outside total n root first steel pipes 8, as shown in Figure 2.
Described down center pulling force strop 62 is lower ends of being passed through inner ring strut 41 by a drag-line successively; And form a ring; One first steel pipe 8 of every section drag-line overcoat of pulling force strop 62 at following center; Its length is the distance between the inner ring strut,, center pulling force strop 62 outside total n root first steel pipes 8 down.
One end of notochord 2 is anchored on the side ring beam 1, and the other end of notochord 2 is connected with last center pulling force strop 61, and notochord 2 is radial to arc lower; Constitute by the multistage drag-line is continuous; The turning point of the upper end of jury strut 42 and notochord 2 is hinged, and the lower end of jury strut 42 and outmost turns radially an end and the strop 3 of rope 5 are hinged, and the outmost turns radially other end of rope 5 also is anchored on the side ring beam 1; The inner ring radially turning point of an end and the notochord 2 of rope 5 is hinged; The inner ring radially other end of rope 5 is hinged with the lower end of inner ring strut 41, and initiatively an end of rope 7 is connected the middle part of inner ring strut 41, and the other end is anchored on side ring beam 1 contact.
Described strop 3 is along the hoop closed arrangement; Each ring is the end that a drag-line passes jury strut 42 successively; The length of one second steel pipe 9, the second steel pipes 9 of cover is the distance between the jury strut 42 on the every section strop 3 between the jury strut 42, and is as shown in Figure 3.
Described upward center pulling force strop 61 absolute altitudes are the highest, and strut top absolute altitude hoop is identical, radially successively decreases from inside to outside; The described center pulling force strop 61 of going up is with following center pulling force strop 62, notochord 2, strop 3, radially rope 5 is a prestressed cable, and described strut can be metal rod or metal tube, and described side ring beam 1 is a pressurized side ring beam; Generally can use reinforced concrete beam, rigidity is big, and the pressurized performance is good; Construction is also convenient, radially rope 5, initiatively the steel plate used of the anchoring of rope 7 and notochord 2 can be embedded on this beam, the tension operation space is spacious; 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: loosening the constraint of the center of going up pulling force strop 61 and following center pulling force strop 62 and every strop 3, the prestressing force of cable dome structure is removed, also is 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 the rope dome to cover is increasing, is reduced to minimum until the length of active rope 7, and the opening process of structure finishes; Structural configuration in the opening process is as shown in Figure 4, and first steel pipe 8 is as shown in Figure 5 in motion process.
Radially open-type cable dome structure closing course is: loosen the initiatively constraint of rope 7; Center pulling force strop 61 and following center pulling force strop 62 and strop 3 in the continuous stretch-draw; Last center pulling force strop 61 reduces with the length of following center pulling force strop 62 and strop 3; Thereby all rod members are constantly moved to the middle part, and the length that equals length and every section strop 3 of first steel pipe 8 until every section length that goes up center pulling force strop 61 and following center pulling force strop 62 equals the length of second steel pipe 9, continues center pulling force strop 61 and following center pulling force strop 62 and strop 3 in the stretch-draw; Make to produce prestressing force in the rod member, thereby make mechanism become structure.
Cable dome structure for routine; Its prestress distribution can be tried to achieve through the balancing matrix theory; Pulling force strop 61 has overlapped a steel pipe with following center pulling force strop 62 and strop 3 outsides and the utility model is at last center, its prestressing force mode change, its calculating sketch map is as shown in Figure 6.
T 1Give the pulling force of center pulling force strop 61 or following center pulling force strop 62 or strop 3 from stress mode for cable dome structure itself;
T 2For with steel pipe in pressure
