Description

Annular cross-woven cable net structure, stereoscopic city dome and large-span building dome

With the advancement of human civilization and the development of construction technology, it is a desire to continually challenge the scale, height and span of buildings. In recent years, the idea of building ultra-high and ultra-large stereoscopic cities is raised. However, there are a series of technical problems to be solved in order to realize the envisaged stereoscopic city.

If the building diameter of the huge stereo city with strong functionality and markedness is set to be more than kilometers, the corresponding building area can reach millions of square meters, and the building height can also exceed kilometers. Under the assumption, the three-dimensional city building has huge volume, huge building height and structure span, and the structural height and the cross section size of members of rigid systems such as trusses, net racks and the like are increased, so that the steel consumption is increased rapidly. In addition, because the number of the rods is dense, the construction decoration measures are required to be additionally adopted, so that the structural weight, the earthquake force and the engineering cost are further increased, and the requirements of natural lighting and green ecology of the three-dimensional city are difficult to meet.

The foundation bearing capacity, lateral rigidity and other heavy technical bottlenecks of the ultra-high building are removed, and the foundation structure further comprises the problems of supporting and balancing adjustment of the ultra-high structure, including the problem of natural light utilization of a three-dimensional city and the like.

When the structural span is more than 120m, the cross section of the common structural system member is rapidly increased, so that the steel consumption is large, and the use requirements of light, transparent, lighting and the like of the dome roof can not 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.

The technical difficulties of lighting and supporting super high-rise structures limit the construction of large-span buildings and three-dimensional city super high-rise buildings. To construct a stereoscopic city of good quality, a new stereoscopic city dome structure must be created.

Detailed Description

The following detailed description of preferred embodiments of the invention is made in connection with the accompanying drawings, which form a part hereof, and together with the description of the embodiments of the invention, are used to explain the principles of the invention and are not intended to limit the scope of the invention.

The following describes the technical scheme of the present invention in more detail with reference to fig. 1 to 20:

example 1

An annular cross-woven rope net structure.

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

The roof cable net unit 41 is constituted by a cable 44 and a cable clamp. Preferably, the cord clip is a double layer cord clip 43.

The same number of connectors 45 are arranged on the adjacent giant ring trusses, and the connectors 45 are circumferentially and uniformly distributed on the edges of the giant ring trusses; each connector 45 on the same huge ring truss is connected with the first ends of 2 steel ropes 44; the second ends of the 2 steel ropes 44 are connected to different connectors 45 of the adjacent huge ring trusses and are symmetrically arranged relative to the first ends; every 2 crossed wires 44 are connected at the crossing point by a double layer wire clip 43; the connector 45 is an adjustable mount, preferably the connector 45 is a ball adjustment mount.

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

The positioning connector 452 is used for connecting the edge of the huge ring truss, and the positioning fixing body 451 is used for connecting 2 steel ropes 44 with angles. A positioning spherical body 455 with a ball head structure is provided between the positioning fixing body 451 and the positioning connecting body 452, wherein the positioning connecting body 452 has a matching spherical groove at a portion contacting with the spherical surface in the positioning spherical body 455. When the giant ring truss is stressed to generate micro displacement, the steel ropes 44 on each annular cross woven rope net structure can pass through the fine adjustment positions of the spherical surfaces, and damping is formed through different displacements of all the steel ropes 44 on the annular cross woven rope net structure, so that the influence of external factors on super high-rise buildings, especially the central high tower 3, is reduced or even eliminated.

An elastomer positioning vibration reduction unit 453 is arranged between the positioning fixing body 451 and the positioning spherical body 455 and between the positioning spherical body 455 and the positioning connecting body 452, and is used for absorbing vibration, further increasing damping and blocking the transmission of destructive force to the main body structure.

A gap is provided between the positioning fixing body 451 and the positioning connecting body 452, and the positioning sealing unit 454 seals the positioning fixing body 451 and the positioning connecting body 452, so that the rotatable and positioning spherical body 455 is positioned in the closed cavity, and lubricant is conveniently added in the closed cavity in the installation process, so that the positioning spherical body 455 can freely rotate.

As shown in fig. 1 and 3, in particular, the annular building groups are concentrically arranged and divided into an inner annular tower group 23, an intermediate annular tower group 22 and an outer annular tower group 21; correspondingly, the huge 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 ring-shaped cross-woven cable network structure of embodiment 1 includes an inner ring truss 232, a middle ring truss 222, and an outer ring truss 212 of the ring-shaped 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 adjacent giant ring trusses in an annular radial manner.

Further, an outer annular cross-woven cable net 411 is disposed between the inner side of the outer ring truss 212 and the outer side of the middle ring truss 222; an inner endless cross-woven cable net 412 is between the inner side of middle ring truss 222 and the outer side of inner ring truss 232.

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

steel cables

44,4 in 4 different directions can be connected with 2 connectors on the outer side of the middle ring truss 222, the other ends of the other 2 of the 4 steel cables are respectively connected with 2 connectors on the lower side of the outer side of the middle ring truss 222, and the connectors on other points on the inner side of the outer ring truss 212 are sequentially connected in this way to form the double-layer annular cross-woven cable net structure with radial annular arrangement. The advantage of this structure is that the connection is more stable, but because of the extra large amount of raw materials, the load effect needs to be considered compared with the cable net structure used by the dome of the super-large building.

Therefore, as shown in fig. 4, the single-layer annular cross-woven cable net structure is preferably adopted in the invention. Specifically, the steel cables 44 in the outer annular 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 endless cross-woven cable net 412 are connected between the inner upper edge of the middle ring truss 222 and the outer upper edge of the inner ring truss 232. The steel cables 44 and the connected huge ring trusses all form a single-layer annular cross-woven cable net structure.

The steel cables 44 in the cross-woven cable net structure are not vertical and are all arranged in a cross manner, and 2 steel cables use double-layer cable clamps 43 at the crossing positions.

As shown in fig. 12 and 13, the double-layered rope clip 43 includes a double-layered rope clip base plate 431, a double-layered rope clip upper cover plate 432, and a double-layered rope clip lower cover plate 433, which are sequentially connected; a first wire rope hole is formed between the double-layer rope clamp base plate 431 and the double-layer rope clamp upper cover plate 432, and a second wire rope hole is formed between the double-layer rope clamp base plate 431 and the double-layer rope clamp lower cover plate 433; the first and second wire holes are disposed at an angle for connecting 2 intersecting wires 44.

The double-layer cable clamp 43 with different angles can be suitable for the intersecting condition of steel cables with any angle, and the double-layer cable clamp 43 has the advantages of small volume, simple structure, low manufacturing cost and good effect of fastening 2 steel cables with angles.

In the endless, cross-woven wire mesh structure of the present invention, the cross-woven intersections of the wire ropes 44 are connected by double layer clamps to form a wire mesh structure, which greatly improves the structural integrity as compared to each individual radial rope. Although the steel ropes 44 of the endless cross-weave structure are all straight ropes, diamond-shaped grids with rhythm sense can be formed by properly deflecting the angle of the steel ropes between adjacent ring trusses, and the upper surface of the formed roof is changed from straight lines to slightly concave curved surfaces, so that the structure is light and attractive.

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

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

Example 2:

a stereoscopic city dome.

The stereoscopic city dome of example 2, which is used as a stereoscopic city super high rise building roof, comprises a roof cable net unit 41 and an inflatable membrane unit 42. The roof cable net unit 41 includes the endless cross-woven cable net structure of embodiment 1, among others.

The inflatable membrane unit 42 is attached to the roof cable network unit 41 of the cross-woven annular cable network structure to form a roof of the three-dimensional city super high-rise building, namely a three-dimensional city dome, in particular a dome structure 4.

Preferably, the inflatable membrane unit 42 employs ETFE inflatable membrane ethylene-tetrafluoroethylene copolymer. On one hand, the ETFE inflatable film has light weight, good light transmittance, high strength, strong impact resistance and good heat preservation and 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 in enclosing the internal environment of the three-dimensional city; on the other hand, the ETFE inflatable film can not drip and can self-extinguish when being burnt, thereby being beneficial to the fire safety of the three-dimensional city. Also, the roof cable net units 41 of adjacent annular trusses are high in inside and low in outside, which is beneficial to roof drainage.

As shown in fig. 16 and 17, by attaching the inflatable membrane units 42 to the outer annular cross-woven wire mesh 411 and the inner annular cross-woven wire mesh 412, a stereoscopic city dome, i.e., a dome structure 4 of a stereoscopic city with the center high tower 3 can be formed. The stereoscopic city dome is connected with the peripheral annular conjoined structure through the roof cable net unit 41, and the function of the stereoscopic city dome is equivalent to a cable rope (the roof cable net unit 41) of a tower mast structure (the central tower 3), and the multiple huge annular structures are connected into a whole, so that the lateral rigidity of the central high tower base can be effectively improved. The annular cross-woven rope net structure and the stereoscopic city dome structure formed on the basis thereof can be used as a roof at the periphery of a central high tower of a stereoscopic city, and can enable a central high tower foundation ring truss to be connected with the top of a huge annular structure at the outer side through the cross-woven rope net; the high tower in the stereoscopic city can play a role in symmetrically pulling and balancing damping while ensuring good lighting in the stereoscopic city, and can weaken or resist the influence of wind resistance, earthquake and other destructive forces.

The stereoscopic city dome of embodiment 2, namely dome structure 4, is integrally formed by a large-down and small-up body, which is beneficial to reducing the wind resistance area of stereoscopic cities and large-span buildings, reducing the influence of wind load and increasing the lateral rigidity of stereoscopic cities and large-span building structures.

The inflatable membrane unit 42 is attached to the outer annular cross-woven wire mesh 411, the inner annular cross-woven wire mesh 412 and the core large-span roof unit 413.

As shown in fig. 1 and 10, the outer annular cross-woven wire mesh 411, the inner annular cross-woven wire mesh 412 and the large-span roof unit 413 together constitute a roof of a large-span building center square, forming a large-span building dome of example 3.

In connection with fig. 15, the large span building applied to the large span building dome of embodiment 3 further includes a building foundation 1, a giant ring structure.

The large-span super high-rise building forms a huge central square at the center of the inner ring tower body 231, and the large-span roof unit 413 is a roof thereon. The large span super high rise building forms an environmentally controlled space under the structure of the large span building dome of example 3.

The large-span building dome with the annular cross woven rope net structure can greatly break through the limitation of the span of the conventional rope structure by continuously arranging the multiple annular cross woven rope net structure, is suitable for large-span buildings covering millions of square meters and over super-large spaces, has a coverage area equivalent to tens of large-scale stadiums, and provides technical possibility for building urban-level super-large indoor space environments.
