The central rigid ring supporting jig frame 4 and the beam string supporting jig frame 6 are fixed on a foundation.
As shown in fig. 1 and 4, the tension chord 5 includes an upper chord 51, a tension cable 52 and a plurality of tension cable stays 53, the inner end of the upper chord 51 is connected to the top of the central rigid ring 3, and the outer end of the upper chord 51 is connected to the peripheral ring beam 2.
The inner end of a stay cable 52 is connected with the bottom of the central rigid ring 3, the outer end of the stay cable 52 is connected with the peripheral ring beam 2, the upper end of a stay cable stay 53 is connected with the upper chord 51, and the lower end of the stay cable stay 53 is connected with the stay cable 52. The upper chord 51 is supported by the beam support jig 6. As shown in fig. 3, a bracing cable avoiding space is reserved on the bracing beam support jig 6. The beam string supporting jig frame 6 is supposed to avoid the stay cable stay 53. In order to protect the cable 52, a plurality of sleeves 54 are sleeved outside the cable 52, and the sleeves 54 are arranged in a plurality of sleeves, so that the original characteristics of the cable 52 are kept, the tensioning of the cable is not influenced, and the cable 52 can be effectively protected.
As shown in fig. 4, a sliding support 12 is arranged between the central rigid ring 3 and the central rigid ring support jig 4; and a sliding support 12 is arranged between the peripheral ring beam 2 and the concrete wall 1.
