Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building structure design, and in particular to a central high tower base structure. BACKGROUND

[0002] With the progress of human civilization and the development of construction technology, developed countries continue to challenge the scale, height and span of buildings. Among them, the landmark high tower construction has exceeded 1000m. The central high tower relies on the building to further improve the overall height of the landmark building.

[0003] In the prior art, during the construction of the super high-rise building including the central high tower, the main technical bottlenecks include the huge load of the super high-rise building, which requires a foundation that can reasonably distribute the load. The high-rise building foundation generally uses a pile raft foundation. When the building height reaches about 500m, due to the limitation of single pile bearing capacity, the raft area under the tower is insufficient to arrange a sufficient number of foundation piles to support the huge load of the upper structure.

[0004] Another important constraint factor is the lateral stiffness of the central high tower. It is extremely difficult for a single tower to reach a height of more than one kilometer. The monomer tower is limited by the size of the bottom plane, and it is difficult for the super high-rise building to reduce its height-width ratio. The insufficient lateral stiffness causes the structure to sway and is difficult to avoid.

[0005] The above technical difficulties seriously restrict the construction of kilometer-level super high-rise buildings. SUMMARY

[0006] In view of the above analysis, the present application aims to provide a central high tower base structure to solve the technical problems of insufficient lateral stiffness of the central high tower and excessive concentration of vertical force.

[0007] The present application is realized by the following technical solutions:

[0008] A central high tower base structure, comprising a base building foundation and a base building group; the base building group is built on the base building foundation, and the central high tower is built on the base building group; the base building group is a giant ring structure, comprising a base tower body, a base ring truss and a base waist reinforcing ring truss unit; a plurality of base tower bodies are arranged in a ring, the base ring truss is arranged around and connected to the top of each base tower body, and the base waist reinforcing ring truss unit is arranged at the waist of the base tower body; the base building foundation comprises a ring-shaped raft and a base pile foundation; the ring-shaped raft is arranged around the bottom of the base tower body; the giant ring structure refers to a ring structure with a minimum inscribed circle diameter of not less than 200m.

[0009] Further, the annular raft is a ring plate structure, and a radial radius difference is greater than a maximum circumscribed circle radius of a cross section of the base tower body; a plurality of the base tower bodies are uniformly distributed along a circumferential direction of a middle surface of the annular raft; and the base pile foundation is arranged below the annular raft.

[0010] Further, the base pile foundations are uniformly distributed below the annular raft; and a length of the base pile foundation arranged below the base tower body is greater than a length of the base pile foundation arranged at a peripheral position.

[0011] Further, the base pile foundation comprises a base pile column, an upper end of the base pile column is located in the annular raft, a portion of the base pile column below the annular raft is provided with a spiral hoop; and a concrete cushion layer is laid on a lower surface of the annular raft.

[0012] Further, the base tower body comprises a base tower and a base tower core tube; the base tower core tube is arranged in the base tower; and the base tower core tube and the base tower are both connected to the annular raft.

[0013] Further, the base tower core tube is higher than the base tower; the base ring truss is connected to a top of each base tower core tube on the same ring through a ring truss structure; and the base tower core tube is located inside the base tower and close to a center of the mega annular structure of the base building group.

[0014] Further, the base waist reinforcing ring truss unit comprises a plurality of base waist reinforcing ring trusses, the plurality of base waist reinforcing ring trusses are arranged in a spaced manner from top to bottom on the base building group; each base waist reinforcing ring truss is connected to an outer frame column of each base tower on the base building group and extends to connect the base tower core tube.

[0015] Further, the base waist reinforcing ring truss unit comprises a first waist ring truss, a second waist ring truss and a third waist ring truss; the first waist ring truss is arranged below the base ring truss; and the third waist ring truss is located at a lower half of the base tower body.

[0016] Further, a base platform horizontal reinforcing layer is arranged at the base ring truss, and a base movable platform layer is constructed at the first waist ring truss, the second waist ring truss and the third waist ring truss, respectively.

[0017] A three-dimensional urban super high-rise building comprises the central high tower base structure.

[0018] Compared with the prior art, the application can achieve at least one of the following beneficial effects:

[0019] 1. The central high tower base structure of the present application effectively disperses the huge load of the central high tower to each base tower body of the base building group through the base top ring truss on the base building group, thereby reducing the difficulty of solving the problem of concentrated load.

[0020] 2. The annular raft of the central high tower base structure of the present application is equivalent to constructing a continuous foundation girder for the central high tower, dispersing the concentrated load to the entire ring-shaped pile cap, allowing the pile area to be expanded, and improving the bearing capacity of the foundation. By using a pile area much larger than the projected area of the base tower, the problem of the single raft area being difficult to meet the requirements of the lower zone of the central high tower can be solved, thereby overcoming the problem of insufficient foundation bearing capacity and providing a new approach for significantly increasing the building height.

[0021] 3. The base piles under the annular raft of the central high tower base structure of the present application are set to different lengths, which can be beneficial to the variable stiffness leveling of the annular raft and the upper building structure, the deformation adjustment of the annular raft, and the stability of the annular raft and the upper building structure.

[0022] 4. The base tower core tube of the central high tower base structure of the present application is arranged inwardly in the base tower. The inward offset of the base tower core tube satisfies the same building use function as the ordinary super high-rise building, and facilitates the direct elevator transfer to the high-altitude transfer platform.

[0023] 5. The multiple base waist reinforcing ring trusses of the central high tower base structure of the present application can effectively enhance the integrity of the base structure and significantly improve the lateral stiffness of the central high tower base. The base horizontal transfer platform can be built at the top base ring truss. The top base ring, the base horizontal transfer platform, and the multiple base waist reinforcing ring trusses can coordinate the deformation between the base tower bodies, and avoid the torsional effect caused by the eccentric arrangement of the core tube of a single base tower body.

[0024] In the present application, the above technical solutions can be combined with each other to realize more preferred combination schemes. Other features and advantages of the present application will be described in the subsequent specification, and some advantages will become apparent from the specification or be understood by implementing the present application. The purpose and other advantages of the present application can be achieved and obtained through the contents specifically indicated in the specification and the drawings.

[0047] The preferred embodiments of the present application will be described in detail below with reference to the drawings, which form a part of this description, and which are illustrative of the principles of the present application. The application is not limited to the embodiments disclosed but is to be accorded the widest scope consistent with the principles and features disclosed.

[0048] The technical solutions of the present application will be described in detail below with reference to the drawings: Figures 1-16

[0049] Embodiment 1

[0050] Central high tower podium structure.

[0051] The central high tower podium structure comprises a podium building foundation and a podium building group 23.

[0052] As shown in Figure 1 , Figure 2 and Figure 3 , the podium building group 23 is built on the podium building foundation, and the central high tower 3 is built on the podium building group 23; the podium building group 23 is a giant ring structure, comprising a plurality of podium tower bodies 231 and a podium ring truss 232.

[0053] The plurality of podium tower bodies 231 are arranged in a ring, and the podium ring truss 232 is located at the top of the plurality of podium tower bodies 231 and is arranged around and connected to each of the podium tower bodies 231. The podium building foundation comprises a ring-shaped raft 12 and a podium pile foundation 113; the ring-shaped raft 12 is arranged around the podium pile foundation 113. Preferably, a podium platform horizontal reinforcement layer 234 is built depending on the podium ring truss 232. The podium platform horizontal reinforcement layer 234 can serve as a central shared hall and also as a transfer platform during the construction of the central high tower 3.

[0054] As shown in Figure 8 , Figure 9 and Figure 10 ​As shown, the annular raft 12 is a ring plate structure, and the radial radius difference of the ring plate is greater than the maximum circumscribed circle of the cross section of the base tower body 231. Preferably, the radial radius difference of the ring plate is not less than 1.5 times the diameter of the maximum circumscribed circle of the cross section of the base tower body 231. A plurality of base tower bodies 231 are evenly distributed along the circumferential direction of the annular raft 12; and the base pile foundation 113 is arranged below the annular raft 12.

[0055] The base pile foundation 113 is evenly distributed below the annular raft 12; and the length of the base pile foundation 113 can be set to different lengths according to the position. Preferably, the length of the base pile foundation 113 arranged below the base tower body 231 is greater than the length of the base pile foundation 113 arranged at the peripheral position.

[0056] As shown, Figure 11 The base pile foundation 113 includes a base pile column 1131, the upper end of the base pile column 1131 penetrates into the inside of the annular raft 12 and is rigidly connected with the annular raft 12, and is solidified as a whole through the concrete cushion 114 laid on the lower surface of the annular raft 12.

[0057] The part of the base pile column 1131 located outside the annular raft 12 is provided with a spiral hoop 1132; the spiral hoop 1132 is arranged on the upper part of the base pile column 1131 at a local height, and preferably, at least 1 / 3 of the upper part of the base pile column 1131 is wound with the spiral hoop 1132. A plurality of longitudinal stiffening hoops 1133 are also arranged in the axial direction on the base pile column 1131; and the plurality of longitudinal stiffening hoops 1133 are evenly arranged.

[0058] The base pile foundation 113 of this structure is connected with the annular raft 12, which can strengthen the integrity of the base pile foundation 113, improve the supporting effect on the base building group, and further well support the central high tower 3, forming a stable central high tower base structure.

[0059] The bored pile foundation is adopted for the base building foundation, and the total settlement and differential settlement of the central high tower base structure, the building structure thereon and the central high tower 3 are controlled through the thickness of the annular raft 12, the pile diameter and the pile length of the base pile foundation 113.

[0060] Preferably, the base tower body 231 in the embodiment 1 is a total of 6.

[0061] The radial size of the annular raft 12 in the embodiment 1 is greater than the maximum planar size of the base tower body 231 supported thereon, and a plurality of base tower bodies 231 at a long distance are connected on one pile foundation. The base pile foundation 113 is not only arranged below the base tower body 231, but also arranged below the entire annular raft 12, so that the effective pile distribution area is expanded, thereby bearing a larger load. At the same time, the overall strength of the base building group 23 is effectively enhanced.

[0062] Preferably, the base pile foundation 113 is uniformly distributed under the ring-shaped raft 12, and is divided into long and short piles according to the stress condition. Further preferably, longer base pile foundations 113 are arranged directly below the base tower body 231, and shorter base pile foundations 113 are arranged at other places of the ring-shaped raft 12 outside the base tower body 231. The arrangement of long and short base pile foundations 113 can level the rigidity of the ring-shaped raft 12 and the upper building structure thereof, adjust the deformation of the ring-shaped raft 12, and is conducive to the stability of the building and the high tower foundation above the ring-shaped raft 12 and the overall structure.

[0063] The bottom of the base building group 23 adopts the ring-shaped raft 12, which is equivalent to constructing a continuous foundation girder. The ring foundation of the ring-shaped raft 12 breaks the traditional practice of having independent pile-raft foundations for adjacent building structures that are far apart. The continuous foundation girder of the ring-shaped raft 12 can disperse concentrated loads to the entire ring-shaped pile cap, allow the expansion of the pile distribution area, and improve the bearing capacity of the foundation. By arranging the pile distribution area to be much larger than the projected area of the base tower body 231, the problem of being difficult to meet the requirements of pile distribution under the low area of the high tower with a single raft area can be solved, and the problem of insufficient foundation bearing capacity can be overcome, thereby providing a new idea for significantly increasing the building height.

[0064] The typical plane of the tower of the base tower body 231 is shown in Figure 7 Specifically, the base tower body 231 includes a base tower and a base tower core 233; the base tower core 233 is arranged in the base tower; and the base tower core 233 and the base tower are both connected to the ring-shaped raft 12. The base tower core 233 is higher than the base tower; and the base ring truss 232 connects the base tower body 231 through the base tower core 233.

[0065] The base tower body 231 adopts a base tower core 233 made of concrete and a base tower made of a steel pipe concrete column-H shaped steel frame structure system.

[0066] The base ring truss 232 penetrates and connects the base tower core 233 of each base tower body 231. The load of the central high tower 3 and the base ring truss 232 is transmitted downward through the base tower core 233 instead of the base tower, effectively reducing the influence of external forces on the base tower, and protecting the normal use of the base tower.

[0067] Figure 6 The plane arrangement of multiple base tower cores 233 in the base building group 23 is shown.

[0068] Specifically, the base tower core tube 233 is located inside the base tower and close to the center of the mega ring structure of the base building group 23. The base tower core tube is arranged centripetally inside the base tower, so that the public facilities constructed according to the base tower core tube are offset to the inner side of the base building group 23 ring, meeting the building use function of the base tower, which is the same as that of an ordinary super high-rise building, for example, facilitating the direct elevator transfer to the high-altitude transfer platform.

[0069] As shown in FIG. 1, the base platform horizontal reinforcement layer 234 can be constructed according to the base ring truss 232 at the top of the base tower body 231. Figure 12

[0070] The base platform horizontal reinforcement layer 234 can serve as a central shared hall and a transfer platform during construction, as a construction platform for high-altitude large-distance component staged hoisting and concrete staged pumping. In particular, the base platform horizontal reinforcement layer 234 is the lowermost base platform of the central high tower 3, which can more evenly disperse the vertical load of the central high tower 3 to the lower base towers, is conducive to controlling the vertical load borne by each super high-rise building, and is also the most important material transportation and conversion platform for building the central high tower 3.

[0071] Below the base ring truss 232, a base waist reinforcement ring truss unit including a plurality of base waist reinforcement ring trusses is constructed. The plurality of base waist reinforcement ring truss units are longitudinally arranged at different heights of the base tower body 231.

[0072] As shown in FIG. 1, the base platform horizontal reinforcement layer 234 can be constructed according to the base ring truss 232 at the top of the base tower body 231. Figure 3 Figure 4 As shown in FIG. 1, the base platform horizontal reinforcement layer 234 can be constructed according to the base ring truss 232 at the top of the base tower body 231.

[0073] The first waist ring truss 2351, the second waist ring truss 2352, and the third waist ring truss 2353 are respectively connected to the outer frame columns at the corresponding height of each base tower and extend into the base tower core tube 233 at that position, forming a closed ring truss structure.

[0074] Further preferably, the first waist ring truss 2351 is arranged at a position close to the top of the base tower, specifically at the lower part of the base ring truss 232, and the third waist ring truss 2353 is arranged at the lower half of the base tower.

[0075] Further preferably, the first waist ring truss 2351, the second waist ring truss 2352, and the third waist ring truss 2353 are arranged at equal distances.

[0076] ​​Further preferably, the third waist ring truss 2353 is arranged at the lower half of the base tower and close to the middle height position.

[0077] The base waist ring truss unit can be arranged to construct the base movable platform layer.

[0078] The base waist ring truss unit can effectively enhance the rigidity of the base building group 23 as a whole structure and improve the bearing capacity of the central high tower base.

[0079] The first waist ring truss 2351, the second waist ring truss 2352 and the third waist ring truss 2353 can be arranged to construct the base movable platform layer as the central shared hall.

[0080] The base ring truss 232, the base platform horizontal reinforcement layer 234, the base waist ring truss unit and the base movable platform layer can coordinate the deformation between the base towers and effectively avoid the occurrence of the torsion effect of a single tower due to the eccentric arrangement of the base tower core tube 233.

[0081] Embodiment 2:

[0082] A three-dimensional urban super high-rise building.

[0083] The three-dimensional urban super high-rise building includes the central high tower base structure in embodiment 1, and further includes the central high tower 3 and the dome structure, and the outer ring building group and the outer ring pile foundation 111, the middle ring building group and the middle ring pile foundation 112.

[0084] As shown in Figure 15 , the base building group 23, the middle ring building group and the outer ring building group are all giant ring structures arranged on three concentric circles and respectively including the tower body and the ring truss.

[0085] Preferably, the middle surface of each ring truss is coplanar with the annular surface formed by the center of the ring tower body.

[0088] Preferably, the plurality of tower bodies on the outer ring tower body 211, the middle ring tower body 221 and the base tower body 231 are circumferentially distributed and have the same height. The tower bodies on the base tower body 231, the middle ring tower body 221 and the outer ring tower body 211 gradually decrease in height from the inside to the outside, and the radius difference between the middle ring building group and the base building group 23 is greater than the height difference between the base tower body 231 and the middle ring tower body 221, and the radius difference between the outer ring building group and the middle ring building group is greater than the height difference between the middle ring tower body 221 and the outer ring tower body 211.

[0089] The number of tower bodies on the base tower body 231, the middle ring tower body 221 and the outer ring tower body 211 gradually increases from the inside to the outside.

[0090] Preferably, the number of tower bodies increases by equal ratio from the inside to the outside.

[0091] Further preferably, the number of tower bodies increases by equal ratio of 1:2 from the inside to the outside.

[0092] Further preferably, on a diameter line, the outer ring building group, the middle ring building group and the base building group 23 are respectively symmetrically provided with 2 tower bodies.

[0093] In embodiment 2, preferably, the base building group 23 is circumferentially provided with 6 tower bodies, the middle ring building group is circumferentially provided with 12 tower bodies, and the outer ring building group is circumferentially provided with 24 tower bodies.

[0094] Specifically, the height of the tower bodies on the outer ring building group, the middle ring building group and the base building group 23 gradually increases from the outside to the inside. Preferably, the ratio of the radius difference between adjacent rings to the height difference of the tower bodies is greater than 1.

[0095] Each tower body includes a tower and a core tube. A ring truss is built on the top of the core tubes in the same ring. This makes the ring truss and its load transmitted to the base building foundation through the core tubes, thereby not causing destructive impact on the tower.

[0096] The structure of the base building group 23 is as in embodiment 1, and the top of the base tower core tube 233 is higher than the base tower body 231; the base ring truss 232 is connected to the top of each base tower core tube 233 in the same ring through a ring truss structure. The base tower core tube 233 and the base ring truss 232 form an integral whole on the base tower body 231.

[0097] The Central Ring complex comprises the Central Ring Truss 222 and the Central Ring Tower 221. The Central Ring Tower 221 includes the Central Ring Tower Core and the Central Ring Tower itself. The Central Ring Tower Core is located within the Central Ring Tower. The Central Ring Truss 222 connects the tops of all the Central Ring Tower Cores on the same ring at the top of the Central Ring Tower 221, thus forming a whole. The foundation of this part is the Central Ring Pile Foundation 112 under each Central Ring Tower 221.

[0098] The outer ring building complex includes an outer ring truss 212 and an outer ring tower body 211. The outer ring tower body 211 includes an outer ring tower core tube and an outer ring tower. The outer ring tower core tube is located inside the outer ring tower. The outer ring truss 212 connects the tops of all the outer ring tower core tubes on the same ring at the top of the outer ring tower body 211, thus forming a whole. The foundation of this part is the outer ring pile foundation 111 under each outer ring tower.

[0099] Preferably, in Embodiment 2, the outer ring truss 212 and the middle ring truss 222 are cross-woven spoke structures, and the base ring truss 232 is a ring truss structure.

[0100] The foundation of the building in Example 2 is the same as that in Example 1.

[0101] The outer ring pile foundation 111 and the middle ring pile foundation 112 are respectively located below the outer ring tower 211 and the middle ring tower 221, and are set at intervals, which are ordinary base building foundations.

[0102] Preferably, the length of the pile columns in the outer ring pile foundation 111, the middle ring pile foundation 112 and the base pile foundation 113 gradually increases, and the pile columns on the base pile foundation 113 are provided with piles of varying lengths, as in Example 1.

[0103] Example 2 includes the central tower base structure of Example 1, with the central tower 3 constructed on top of the central tower base structure.

[0104] The dome structure comprises roof cable net units and inflatable membrane units. The ring-shaped, radiating roof cable net units are smoothly connected to the central tower 3. The dome structure consists of connectors, steel cables, and [other components]. The steel cables are connected via connectors to interlock in a cross-braided manner. These cross-braided cables are connected between adjacent ring trusses, and the cable intersections are secured with double-layer cable clamps. The connectors have adjustment and vibration damping functions.

[0105] like Figure 15 As shown, specifically in Embodiment 2, the roof cable net unit includes an outer annular cross-woven cable net and an inner annular cross-woven cable net. Specifically, the inner annular cross-woven cable net is disposed between the base ring truss 232 and the middle ring truss 222; the outer annular cross-woven cable net is disposed between the middle ring truss 222 and the outer ring truss 212.

[0106] Preferably, the outer annular cross-woven cable net and the inner annular cross-woven cable net are cross-woven single-layer cable structures.

[0107] In a cross-braided single-layer cable, the crossing cables are not perpendicular to each other, and a double-layer cable clamp is used at the intersection of the two cables.

[0108] Using different double-layer cable clamps can be applied to situations where steel cables intersect at any angle.

[0109] like Figure 14 The double-layer cable clamp consists of a cable clamp base plate, a cable clamp upper cover plate, a cable clamp lower cover plate, and bolts. The cable clamp base plate and the cable clamp upper cover plate are connected to form a first cable clamping hole, and the cable clamp base plate and the cable clamp lower cover plate are connected to form a second cable clamping hole. The axes of the first cable clamping hole and the second cable clamping hole are at an included angle.

[0110] The double-layer cable clamp is small in size, simple in structure, low in manufacturing cost, and provides good fastening effect for two angled steel cables.

[0111] like Figure 16 As shown, connector 45 includes an adjustment fixing body 451, an adjustment connecting body 452, an adjustment damping unit 453, an adjustment sealing unit 454, and an adjustment spherical body 455.

[0112] The adjustable connector 452 connects the edges of the giant ring truss, while the adjustable fixing body 451 connects two angled steel cables 44. An adjustable spherical body 455 with a spherical head structure is provided between the adjustable fixing body 451 and the adjustable connector 452. The portion of the adjustable connector 452 that contacts the spherical surface of the adjustable spherical body 455 has a matching spherical groove. This structure allows the steel cables 44 on each ring-shaped cross-woven cable net structure to be finely positioned by adjusting the spherical surface when the giant ring truss undergoes minor displacement under stress. Through the different displacements of all the steel cables 44 on the ring-shaped cross-woven cable net structure, damping is formed, reducing or even eliminating the impact of external factors on the supertall building, especially the central tower 3.
