In recent years, the concept of building ultrahigh and oversized three-dimensional cities is created. However, there are a series of technical problems to be solved in order to realize the assumed stereo city.

If the diameter of the building of a huge three-dimensional city with strong functionality and strong marking property is set to be more than kilometers, the corresponding building area can reach millions of square meters, and the building height can exceed kilometers. Under the assumption, the quantity of the buildings in the three-dimensional city is huge, the building height and the structural span are also huge, the structural height and the cross-sectional size of the components of rigid systems such as trusses, net racks and the like are increased, and the consumption of steel materials is rapidly increased. In addition, because the quantity of the rod pieces is dense, building decoration measures need to be additionally adopted, the structure weight, the earthquake force and the engineering cost are further increased, and the requirements of natural lighting and green ecology of a three-dimensional city are difficult to meet.

The method removes the major technical bottlenecks of the ultrahigh building, such as foundation bearing capacity, lateral rigidity and the like, and also solves the problems of supporting and balance adjustment of the ultrahigh structure, including the problem of natural light utilization of a three-dimensional city and the like.

When the structural span is larger than 120m, the section of a component of a common structural system is rapidly increased, so that the steel consumption is large, and the use requirements of light, permeability, lighting and the like of a dome roof cannot be met; at the same time, rigid large-span structures are also difficult to accommodate for the effects of relative movement of the support structure.

Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention and not to limit its scope.

The technical solution of the present invention is described in more detail below with reference to fig. 1 to 20:

example 1

An annular cross-woven cable net structure.

As shown in fig. 4, an annular cross-woven cable net structure includes a giant ring truss, a roof cable net unit 41, and a connector 45; the giant ring trusses are arranged at the top ends of the annular building groups, and the roof cable net units 41 are connected between the adjacent giant ring trusses through connectors 45.

The roof cable mesh unit 41 is composed of a wire rope 44 and a cable clip. Preferably, the cable clamp is a double-layered cable clamp 43.

The same number of connectors 45 are arranged on the adjacent giant ring trusses, and the connectors 45 are uniformly distributed on the edges of the giant ring trusses in the circumferential direction; each connector 45 on the same giant ring truss connects the first ends of 2 steel cables 44; the second ends of the 2 steel cables 44 are connected to different connectors 45 of adjacent giant ring trusses and are symmetrically arranged relative to the first ends; each 2 crossed steel cables 44 are connected at the crossing points by a double-layer cable clamp 43; the connector 45 is an adjustable mount and preferably the connector 45 is a ball-point mount.

As shown in fig. 11, the connector 45 of the ball adjustment support includes a positioning fixing body 451, a positioning connecting body 452, a positioning damping unit 453, a positioning sealing unit 454, and a positioning spherical body 455.

The positioning connector 452 is used to connect the edge of the giant ring truss, and the positioning fixing body 451 is used to connect 2 steel cables 44 with angles. A positioning spherical body 455 with a ball head structure is arranged between the positioning fixing body 451 and the positioning connecting body 452, wherein a matching spherical groove is arranged at a part of the positioning connecting body 452, which is in contact with a spherical surface in the positioning spherical body 455. The structure can enable the steel cable 44 on each annular cross braided cable net structure to pass through the fine adjustment position of the spherical surface when the giant ring truss is stressed to generate small displacement, and damp is formed through different displacements of all the steel cables 44 on the annular cross braided cable net structure, so that the influence of external factors on a super high-rise building, particularly a central high tower 3, is reduced or even eliminated.

A positioning vibration damping unit 453 of elastic body is arranged between the positioning fixing body 451 and the positioning spherical body 455 and between the positioning spherical body 455 and the positioning connector 452 for vibration damping, so as to further increase the damping and block the transmission of destructive force to the main structure.

A gap is formed between the positioning fixing body 451 and the positioning connecting body 452, and the rotatable and positioning spherical body 455 is sealed by the positioning sealing unit 454, so that the rotatable and positioning spherical body 455 is located in the sealed cavity, and a lubricant is added into the sealed cavity during the installation process, so that the rotatable and positioning spherical body 455 can rotate freely.

As shown in fig. 1 and fig. 3, specifically, the annular building groups are concentrically arranged and divided into an inner ring tower group 23, a middle ring tower group 22 and an outer ring tower group 21; correspondingly, the giant ring truss is divided into an inner ring truss 232, a middle ring truss 222 and an outer ring truss 212.

The giant ring truss of the annular cross-woven rigging network structure of example 1 includes an inner ring truss 232, a middle ring truss 222 and an outer ring truss 212 of the annular building group.

Further, the roof cable net unit 41 includes an outer annular cross-woven cable net 411 and an inner annular cross-woven cable net 412, and the outer annular cross-woven cable net 411 and the inner annular cross-woven cable net 412 are respectively connected between the adjacent giant ring trusses in an annular radial shape.

Further, an outer annular cross-woven cord net 411 is provided between the inner side of the outer ring truss 212 and the outer side of the middle ring truss 222; an inner looped cross-woven cord mesh 412 is between the inside of the middle loop truss 232 and the outside of the inner loop truss 232.

Alternatively, both the outer annular cross-woven cable net 411 and the inner annular cross-woven cable net 412 may be provided in a single-layer annular cross-woven cable net structure or a double-layer annular cross-woven cable net structure. As shown in fig. 14, a plurality of connectors are uniformly distributed on the inner side of the outer ring truss 212, and each uniformly distributed point position can be connected with 2 connectors 45 (or a positioning connector 452 of one connector 45 is provided with 4 direction connectors), 2 other ends of 2 of 4

steel cables

44,4 can be connected with 2 connectors on the outer side upper edge of the middle ring truss 222, the other 2 other ends of the 4 steel cables are respectively connected with 2 connectors on the outer side lower edge of the middle ring truss 222, and connectors at other point positions on the inner side upper edge of the outer ring truss 212 are sequentially connected in this way, so as to form a radial annularly-arranged double-layer annular cross-woven cable network structure. The advantage of this structure is that the connection is more stable, but compared with the cable net structure used for the dome of the super-high building, the influence of the load needs to be considered because of the large amount of raw materials.

Therefore, as shown in fig. 4, it is preferable that the present invention adopts a single-layer annular cross-woven cord net structure. Specifically, the steel cables 44 in the outer ring-shaped cross-woven cable net 411 are connected between the upper edge of the inner side of the outer ring truss 212 and the upper edge of the outer side of the middle ring truss 222; the steel cables 44 of the inner ring cross-woven cord net 412 are connected between the upper edge of the inner side of the middle ring truss 232 and the upper edge of the outer side of the inner ring truss 232. The steel cables 44 and the connected giant ring trusses each form a single layer annular cross braided cable mesh structure.

The steel cables 44 in the cross-woven cable net structure are not vertical and are arranged in a cross mode, and double-layer cable clamps 43 are used for 2 steel cables at the cross positions.

As shown in fig. 12 and 13, the double-layer cable clamp 43 includes a double-layer cable clamp base plate 431, a double-layer cable clamp upper cover plate 432, and a double-layer cable clamp lower cover plate 433, which are connected in sequence; a first steel cable hole is formed between the double-layer cable clamp base plate 431 and the double-layer cable clamp upper cover plate 432, and a second steel cable hole is formed between the double-layer cable clamp base plate 431 and the double-layer cable clamp lower cover plate 433; the first and second cable holes are angled to connect 2 crossed cables 44.

The use of different double-layer cable clips 43 can be suitable for the intersection condition of the steel cables at any angle, and the double-layer cable clips 43 have the advantages of small volume, simple structure, low manufacturing cost and good effect of fastening the 2 steel cables at the angle.

In the annular cross-woven cable net structure of the present invention, the cross points of the cross weaving of the steel cables 44 are connected into a cable net structure by double-layered cable clamps, and the structural integrity is greatly improved compared with each independent single radial cable. Although the steel cables 44 in the annular cross-woven structure are straight cables, a rhombus grid with a rhythmic feeling can be formed by properly deflecting the angles of the steel cables between the adjacent ring trusses, the upper surface of the formed roof is changed from a straight line to a slightly concave curved surface, and the structure is light and attractive.

The annular cross braided cable net structure uses a steel cable material with the strength far higher than that of common steel, single-layer cross braided cable nets are arranged between adjacent annular trusses to form a dome of a large-span roof structure, and the adaptability of the dome roof to temperature change can be obviously improved while the steel consumption is greatly reduced and the weight is light.

The cable net spacing density of the annular cross woven cable net structure is adjustable, and the density can be set according to specific environment, so that the lateral rigidity of the super high-rise building structure is obviously improved.

Preferably, the inflatable membrane unit 42 is an ETFE inflatable membrane ethylene-tetrafluoroethylene copolymer. On one hand, the ETFE aerated film has light weight, good light transmission, high strength, strong impact resistance and good heat insulation performance, can meet the requirements of natural light irradiation in a three-dimensional city, has good energy-saving effect in the three-dimensional city, and can play a role of enclosing the internal environment of the three-dimensional city; on the other hand, the ETFE inflatable membrane can not drip and can be self-extinguished during combustion, thereby being beneficial to the fire safety of a three-dimensional city. In addition, the roof cable net units 41 of the adjacent annular trusses are high inside and low outside, so that roof drainage is facilitated.

As shown in fig. 16 and 17, a three-dimensional urban dome of a three-dimensional city with a central tall tower 3, i.e., a dome structure 4, can be formed by attaching inflatable membrane units 42 on outer annular cross-woven cable net 411 and inner annular cross-woven cable net 412. The stereo city dome is connected with the peripheral annular conjoined structure through the roof cable net unit 41, the stereo city dome has the function of being equivalent to a cable rope (the roof cable net unit 41) of a tower mast structure (a central tower 3), and the multiple giant annular structures are connected into a whole, so that the lateral rigidity of a central high tower base can be effectively improved. The annular cross braided cable net structure and the three-dimensional city dome structure formed on the basis of the annular cross braided cable net structure can be used as a roof around a central high tower of a three-dimensional city, and a central high tower base ring truss can be connected with the top of a huge annular structure at the outer side through the cross braided cable net; the lighting system can ensure good lighting in the stereo city, simultaneously can play the roles of symmetrical pulling and balanced damping on the central high tower of the stereo city, and can weaken or resist the influence of destructive forces such as wind resistance, earthquake and the like.
