Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and in particular to a fully tensioned spoke-type cross-cable truss structure system and a construction method thereof. Background Art

[0002] In recent years, with the increasing demand for large-span space structures in large public buildings (such as stadiums, convention centers, transportation hubs, etc.), the fully tensioned cable truss structure system has gradually become an important technical direction for achieving ultra-large-span coverage due to its characteristics of light weight, high strength, and flexible form.

[0003] However, the fully tensioned cable truss structure system in the prior art still has some limitations and deficiencies in practical applications. First, rigid compression bars or local compression members are often introduced in traditional cable truss structures, which are prone to buckling or yielding failure under complex loads (such as wind loads, snow loads, and asymmetric loads). Second, in the existing cable truss structure system, when facing dynamic loads or sudden changes in local loads, the cable body is prone to slip, resulting in the distortion of the cable truss structure form, and then causing stress concentration and even structural instability, resulting in insufficient anti-collapse ability in some areas and being unable to effectively cope with the changing load environment. In addition, some cable truss structures do not have an inner ring cable structure, which is limited in plane and space layout. Finally, most of the existing cable truss structure systems are single-layer structures. In the case of greater span requirements, the single-layer structure may have insufficient rigidity and cannot bear the load.

[0004] How to solve the above technical problems is the subject faced by the present invention. Summary of the Invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides a fully tensioned spoke-type cross-cable truss structure system and a construction method thereof, which have strong structural anti-collapse ability, can adapt to complex load conditions, have high robustness, and meet the rigidity requirements of ultra-large-span structures.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: The present invention provides a fully tensioned spoke-type crossed cable truss structure system, which includes a first support column system, a second support column system, a first compression ring beam, a second compression ring beam, a first crossed cable net, a second crossed cable net, a first inner ring cable structure, a second inner ring cable structure, a number of suspension cables, and a number of scissors braces. The first compression ring beam is arranged on the first support column system and fixedly connected to the first support column system. The second support column system is arranged on the first compression ring beam. One end of the second support column system is fixedly connected to the first compression ring beam, and the other end is fixedly connected to the second compression ring beam. One end of the first crossed cable net is connected to the first compression ring beam, and the other end is connected to the first inner ring cable structure. One end of the second crossed cable net is connected to the second compression ring beam, and the other end is connected to the second inner ring cable structure. A number of the suspension cables are vertically arranged between the first crossed cable net and the second crossed cable net. A number of the scissors braces are hinged to the first support column system and the second support column system. Both the first crossed cable net and the second crossed cable net include a number of radial cables, and the number of the radial cables are cross-arranged and fixed at the crossing points by anchor-type cable clamps.

[0007] The crossed cable net is woven and crossed by a number of radial cables, and fixed at the crossing points by anchor-type cable clamps, so that the crossed cable net can maintain a fixed position without slipping under the stress state, ensuring uniform grid distribution and avoiding the possible instability when local areas are subjected to external forces or uneven loads.

[0008] Preferably, the first compression ring beam and the second compression ring beam are any one of a box girder, a steel truss girder, a concrete beam, and a steel-concrete composite beam. The first compression ring beam and the second compression ring beam are of the same size and concentrically arranged.

[0009] Preferably, the longitudinal projections of the first crossed cable net and the second crossed cable net coincide. At the intersection of any two radial cables of the first crossed cable net and the first inner ring cable structure, a first cable node is provided. One end of the first cable node is fixedly connected to the first inner ring cable structure, and the other end is hinged to any two radial cables of the first crossed cable net through an ear plate and a sleeve. At the intersection of any two radial cables of the second crossed cable net and the second inner ring cable structure, a second cable node is provided. One end of the second cable node is fixedly connected to the second inner ring cable structure, and the other end is hinged to any two radial cables of the second crossed cable net through an ear plate and a sleeve.

[0010] At the intersection of any two radial cables of the first crossed cable net and the first compression ring beam, a third cable node is provided. One end of the third cable node is fixedly connected to the first compression ring beam, and the other end is hinged to any two radial cables of the first crossed cable net through an ear plate and a sleeve; at the intersection of any two radial cables of the second crossed cable net and the second compression ring beam, a fourth cable node is provided. One end of the fourth cable node is fixedly connected to the second compression ring beam, and the other end is hinged to any two radial cables of the second crossed cable net through an ear plate and a sleeve.

[0011] The radial cables of the first crossed cable net and the second crossed cable net are respectively hinged to the first compression ring beam, the first inner ring cable structure, the second compression ring beam, and the second inner ring cable structure through ear plates and sleeves, enabling the radial cables to freely vary within a certain angle range, forming positive and negative Gaussian curves to constitute a stable cable net structure system. The positive Gaussian curve structure part resists the external load effect, and the negative Gaussian curve structure part resists wind suction, being able to adapt to complex load conditions.

[0012] Preferably, one end of several sling cables is fixedly connected to the anchoring cable clamp and the first cable node of the first crossed cable net, and the other end is fixedly connected to the anchoring cable clamp and the second cable node of the second crossed cable net.

[0013] By connecting the first crossed cable net 5 and the second crossed cable net 6 through the sling cable 9, the first crossed cable net 5, the sling cable 9, and the second crossed cable net 6 form a cable truss structure, breaking through the span limit of the single-layer cable net and adapting to the dispersion requirements of larger loads.

[0014] Preferably, both the first inner ring cable structure and the second inner ring cable structure include at least one inner ring cable, and the inner ring cable adopts a continuous cable.

[0015] When the structure span is greater than 100m, it is necessary to consider that the inner ring cable is composed of multiple ring cables to increase the robustness and anti-collapse ability of the inner ring cable. The inner ring cable adopts a continuous cable, effectively reducing the difficulty of construction tensioning and forming.

[0016] Preferably, the radial cable, the inner ring cable, and the sling cable all adopt any one of a sealed cable, a high-vanadium cable, or a carbon fiber cable.

[0017] Preferably, both the first support column system and the second support column system include several support columns, and the support columns are made of at least any one of square steel pipes, circular steel pipes, lattice columns, and concrete columns; the cross braces are made of at least any one of flat steel, angle steel, and round steel, and several cross braces are arranged at intervals or multiple columns are arranged at intervals between several support columns.

[0018] Preferably, a friction material is provided in the groove of the anchored cable clamp. By providing the friction material, the friction force between the groove and the cable body is increased, further improving the stability of the cable net structure.

[0019] The present invention also provides a construction method for a fully tensioned spoke-type cross-cable truss structure, including the following steps:

[0020] S1. Determine the position of the first support column system according to the design drawings and fixedly install it;

[0021] S2. Piece together the first compression ring beam section by section on the working plane formed at the top of the first support column system, and fixedly connect the first support column system and the first compression ring beam;

[0022] S3. Arrange diagonal braces at intervals or among multiple columns between several support columns of the first support column system, and hinge the diagonal braces to the support columns; install the second support column system on the first compression ring beam, and fixedly connect the first compression ring beam and the second support column system;

[0023] S4. Piece together the second compression ring beam section by section on the working plane formed at the top of the second support column system, and fixedly connect the second support column system and the second compression ring beam. Arrange diagonal braces at intervals or among multiple columns between several support columns of the second support column system, and hinge the diagonal braces to the support columns;

[0024] S5. Assemble the first cross-cable net and the second cross-cable net within the site enclosed by the first support column system, fixedly connect the cross nodes of the radial cables through anchored cable clamps, and respectively hinge the assembled first cross-cable net and second cross-cable net to the first inner ring cable structure and the second inner ring cable structure through sleeves and ear plates;

[0025] S6. Fix one end of the sling to the anchored cable clamp and the first cable node of the first cross-cable net, and the other end to the anchored cable clamp and the second cable node of the second cross-cable net;

[0026] S7. Connect one end of the tooling cable to the second cable node on the second inner ring cable structure, and the other end to the fourth cable node on the second compression ring beam. Connect the tooling cable through a synchronous hydraulic lifting device, lift the first cross-cable net and the second cross-cable net to the design elevation, respectively hinge them to the first compression ring beam and the second compression ring beam, install the catwalk, disassemble the tooling cable, and check the installation quality;

[0027] S8. After the main structure is stable, construct the secondary roof steel structure, roof covering film or other covering structures, and construct the maintenance structure around the main structure;

[0028] S9. Complete the construction of the overall structure and comprehensively check the construction quality.

[0029] The beneficial effects of the present invention are as follows: The adoption of the fully tensioned cable structure system avoids compressive yield failure, can adapt to complex load conditions, and meets the rigidity requirements of super-large-span structures. The cross-cable net nodes are fixed by anchored cable clamps, which are smaller in size, and at the same time effectively prevent the cross-cable net from slipping under force, avoiding the instability that may occur when local areas are subjected to external forces or uneven loads. Friction materials are arranged in the grooves of the cable clamps to increase the friction force between the grooves and the cable bodies, further improving the stability of the cable net structure. The first cross-cable net and the second cross-cable net are connected by suspension cables to form a cable truss structure, with a clear force transmission path, effectively avoiding compressive yield failure. The cable truss structure connects the first inner ring cable structure and the second inner ring cable structure, solving the problem of limited plane and spatial layout of the cross-cable truss without the inner ring cable structure system, breaking through the span limit of the single-layer cable net, and adapting to the dispersion requirements of larger loads. The radial cables, suspension cables, and inner ring cables adopt structures such as carbon fiber cables, effectively reducing the self-weight of the structure. The inner ring cables adopt continuous cables, effectively reducing the difficulty of tensioning and forming. The scissors braces are arranged at intervals between the support columns or between multiple columns at intervals, increasing the overall stability and lateral displacement resistance stiffness of the structure.
