The ring cables 1 can slide relative to the retaining ring 9, the ring cables 1 of each layer are annularly opened, and the length of the ring cables 1 can be adjusted in a telescopic mode. In some preferred modes, the retaining ring 9 and the self-lockable pulley 5 are not connected with each other and do not interfere with each other.
In some preferred modes, the ridge cables connect the upper end points of two adjacent layers of the nearest support rods 3, and the ridge cables between the layers can be controlled independently. One end of the ridge cable at the outermost layer is connected with the upper end point of the brace rod 3 closest to the adjacent layer, and the other end is connected with the outer ring beam 10. The ridge cable does not penetrate through the retaining ring or is not connected with the retaining ring, and the position relation between the ridge cable and the retaining ring is not influenced. Similarly, the ridge cable does not pass through the self-locking pulley and is not connected with the self-locking pulley, and the position relationship between the ridge cable and the self-locking pulley is not influenced.

The drawing control of different ring cables 1 is preferably symmetrically distributed along different cable trusses, and fig. 3 and 4 show the condition that the inner pull ring cables 1 are distributed along the symmetrical cable trusses.
As shown in fig. 5, the stay rod 3 and the diagonal rod 4 are connected by a one-way node 8 with a torsion spring. In the process of unfolding and folding the cable dome, the one-way node 8 limits the stay bar 3 and the inclined bar 4 to be folded and unfolded only along a determined motion path under the traction of the auxiliary cable, so that the condition that the motion path of the mechanism is forked is avoided. When the stay bar 3 and the diagonal bar 4 are folded, the torsion spring in the one-way node 8 is compressed, so that the stay bar 3 and the diagonal bar 4 have the tendency of relatively unfolding, tension is generated in the auxiliary cable, and the single cable truss has enough rigidity in the folding and unfolding processes.
In the folding and unfolding process and the layered use state of the cable dome structure, the auxiliary cable and the ring cable 1 are in a tension state by the length adjustment and matching of the auxiliary cable and the ring cable 1, so that the structure is ensured to have sufficient rigidity and overall stability.
Preferably, the cable dome structure is adapted to be folded and unfolded symmetrically, the lengths of the auxiliary cable and the looped cable are adjusted by the winding device at the outer ring beam 10 during the folding and unfolding process to satisfy a certain quantitative relationship, and the length quantitative relationship of the auxiliary cable and the looped cable during the symmetrical folding process according to the preferred embodiment of the present invention is described by taking fig. 6 as an example:
between two layers of support rods, two triangles formed by the support rods, the diagonal rods and the auxiliary ropes are used as basic calculation units, and for example, delta ijk is a basic calculation unit. The fully unfolded state between two layers of stay bars is used as an initial state, and the length of an auxiliary cable in the initial state is l0(i.e., the length of ik) and the length of the looped cable is S0＝C0+l0(C0The initial length of the circumference of the ring cable), the distance from the end point i of the stay rod to the stay rod jk is h0. In the folding process, the brace rod is always kept in a vertical state according to the symmetry, the distance from the end point i to the brace rod jk is recorded as h, and h belongs to [0, h ∈0]And calculating the length l of the auxiliary rope according to the geometrical relationship as follows:
wherein, n is the length of vaulting pole, and m is the length of down tube, and when folding in-process certain position, length l of supplementary cable.
Then, from the initial state to a certain position in the folding process, the variation of the length of the auxiliary rope is:
Δl＝l0-l (2)
at a certain position in the folding process, the length S of the ring cable in the calculating unit is as follows:
then, from the initial state to a certain position in the folding process, the variation of the length of the looped cable is:
ΔS＝S-Se＝2π(h0-h)-Δl (5)
to make the variation a positive value, let Δ l ═ l0-l。
The folding and unfolding process of the cable dome structure is specifically explained by taking a 3-ring 6-petal rib ring type cable dome as an example, and is shown in figures 6 and 7. It should be noted that (i), (ii), and (iii) used in the following description refer to numbers of the rings in the direction toward the outer ring beam 10 along the geometric center of the cable dome.
The folding process of the rib ring type foldable unfolding cable dome (folding from the fully unfolded state) comprises the following steps:
firstly, the first layer of ring cables 1 (namely the upper ring cables 1 and the lower ring cables 1 of the inner pull ring) are loosened under the control of a winding device, the lengths of the other layers of ring cables 1 are kept unchanged, auxiliary cables (an upper chord auxiliary cable 6 and a lower chord auxiliary cable 7) are tightened by the winding device arranged at an outer ring beam 10 at the same time for each roof truss, the first layer of support rods 3 are drawn to the second layer of support rods 3 by the auxiliary cables, torsion springs in one-way nodes 8 are compressed, and all pulleys are in a rotatable state in the process.
When the first layer structure of the cable dome is folded, the next layer of cable dome is folded, the first layer of cable dome 1 is controlled to be loosened and lengthened simultaneously, the lengths of the other layers of cable dome 1 are kept unchanged, the auxiliary cables (the upper chord auxiliary cable 6 and the lower chord auxiliary cable 7) of each cable truss are continuously tightened, and the first layer supporting rod 3 and the second layer supporting rod 3 are drawn to approach the third layer supporting rod 3 by the auxiliary cables.
The folding rule is as follows: during the folding process of each layer, the pulleys are kept in a rotatable state, the ring cables 1 of the folded or folded structures of each layer are synchronously loosened, the length of the ring cables 1 of the unfolded structures of each layer is kept unchanged, and the pulleys are locked in the fully folded or partially folded using state of the cable dome. According to the rule, the cable dome structure can be folded layer by layer from inside to outside. When the first layer of stay rods, the second layer of stay rods and the third layer of stay rods 3 are all pulled to the outer ring beam 10, the cable dome structure is completely folded.
The unfolding process of the rib-ring type foldable unfolding cable dome structure (when the structure is unfolded from the fully folded state) as shown in fig. 8 comprises the following steps:
and simultaneously controlling to tighten each layer of ring cables 1 through a winding device, synchronously loosening the upper chord auxiliary cable 6 and the lower chord auxiliary cable 7 through each cable truss, and gradually unfolding the layer of support rods 3 under the traction of the ring cables 1 when each pulley is in a locked state.
When the layer structure of the cable dome is unfolded, the next layer of cable dome is unfolded, the layer supporting rods 3 reach the designed position, the length of the layer ring cables 1 is kept unchanged, the other layers of ring cables 1 are tightened simultaneously, the auxiliary cables of the cable trusses are loosened continuously, the pulleys at the two ends of the layer supporting rods 3 are in a rotatable state, the other pulleys are locked, and the layer supporting rods 3 are gradually unfolded under the traction of the ring cables 1.
The expansion rule is as follows: when a certain layer of stay bar 3 is pulled to a designed position, the layer of structure is unfolded, in the later unfolding process, pulleys at two ends of the layer of stay bar 3 can rotate, the length of the corresponding layer of ring cable 1 is kept unchanged, the pulleys at two ends of the rest layers of stay bars 3 which are unfolded or not unfolded are locked, and the corresponding layers of ring cables 1 are synchronously tightened. According to the rule, the cable dome structure can be unfolded layer by layer from outside to inside. When the layer strut 3 is pulled to the design position, the cable dome structure is completely unfolded.
Compared with the traditional rib ring structure construction mode, the installation construction of the structure under the completely folded state has obvious advantages, and the specific installation implementation process is as follows:
(1) firstly, mounting a peripheral outer ring beam 10;
(2) then, pre-assembling a single cable truss on the ground, installing and connecting a ridge cable 2, a support rod 3, an inclined rod 4, a self-locking pulley 5, a one-way node 8, an upper chord auxiliary cable 6, a lower chord auxiliary cable 7 and a retaining ring 9,
(3) the auxiliary cables are tightened to enable the supporting rods of all layers to be completely folded, and then all self-locking pulleys are kept locked;
(4) then lifting each cable truss in a folded state to a designated position at the outer ring beam 10, connecting an auxiliary cable to a hoisting device at the outer ring beam 10, and connecting an outermost ridge cable and an inclined rod with the outer ring beam 10;
(5) finally, lifting and installing each layer of ring cables, enabling the ring cables to penetrate through the corresponding rigid retaining rings 9, enabling the rest lengths to be connected to each winding device at the position of the outer ring beam 10, and adjusting cable force through cable length adjustment of the winding devices to enable the structure to achieve the designed shape. Thus, the installation of the invention is completed in a fully folded state.
