The core tube is a building structure in which the central core tube is formed by enclosing the space such as an elevator shaft, stairs, a ventilation shaft, a cable shaft, a public toilet, a part of equipment room and the like at the central part of a building, and an outer frame inner cylinder is formed by the core tube and a peripheral frame. The structure is very favorable for structural stress and has excellent shock resistance, so the structure is a mainstream structural form widely adopted by international high-rise buildings. Meanwhile, the core tube structure has the advantages that the using space as wide as possible can be obtained, various auxiliary service spaces are concentrated towards the center of the plane, the main function space occupies the optimal lighting position, and the effects of good sight and convenient internal traffic are achieved.

Along with the development of society and economy, high-rise buildings are affected by various factors such as planning, site conditions, building functions and the like, and building elevation forms are diversified. Because of the different requirements of the upper and lower parts of the high-rise building on the use function and space requirement, the vertical members (i.e. the upright posts) of the upper floor cannot directly and continuously run through and land, and a conversion layer is required to be arranged for conversion connection of the upper vertical members and the lower vertical members.

The upper and lower parts of a high-rise building are illustratively different in terms of the plane usage function, so that the upper and lower parts of one of the floors take different structural types and are structurally converted by this floor, which is then referred to as a structural conversion floor. If the high-rise building is mostly used for low-rise business, the multifunctional requirement of upper accommodation is that a certain structural form is often adopted to perform conversion treatment between a large space required by the low-rise business and a small space required by the upper accommodation, namely, a conversion layer is additionally arranged. Common structural forms for the conversion layer include beam, hollow truss, diagonal truss, box and slab. In addition, in the house design, the functions of the upper layer and the lower layer are different, and the structure of the floor wall body and the like is reinforced, so that conversion treatment is carried out.

Wherein the conversion layer can be used for the connection stress conversion between the upper vertical member (such as a column) and the lower vertical member (such as a column) through an annular beam structure. Based on this, as shown in fig. 1, the embodiment of the present application provides a conversion system 100 of a diagonal bracing ring beam structure, and the conversion system 100 of the diagonal bracing ring beam structure includes a lower building 10, a conversion layer 20 and an upper building 30 from bottom to top in sequence. In this manner, the vertical members in the upper building 30 and the vertical members in the lower building 10 may be converted by the conversion layer 20 so that the lower building 10 may support the upper building by the conversion layer 20. In this way, even if the vertical members in the upper building 30 cannot continuously pass through and land, different structural arrangements between the upper building 30 and the lower building 10 can be satisfied to realize different use functions. Furthermore, by the arrangement of the conversion layer 20, the building facade forms of the upper building 30 and the lower building 10 can also be made diversified, so that a flexible design of the building space in the upper building 30 and the lower building 10 is facilitated.

In some embodiments, as shown in fig. 2, fig. 2 is a schematic partial structural view of the conversion system 100 of the diagonal ring beam structure shown in fig. 1. The main structure of the conversion system 100 of the diagonal ring beam structure may include a core tube 1 and an outer frame 2, the core tube 1 may be located in the outer frame 2, that is, the outer frame 2 may be distributed around the core tube 1 (that is, the core tube 1 is located in the outer frame 2) around an axis parallel to the up-down direction (that is, the vertical direction), and the core tube 1 may be connected with the outer frame 2 to form the overall frame structure of the conversion system 100 of the diagonal ring beam structure.

With continued reference to fig. 2, the outer frame 2 may include a plurality of support structures 21, a transition ring beam 22, a plurality of tie beams 23, and a plurality of upper columns 24. The conversion ring beam 22 may be arranged along the circumferential direction of the core barrel 1 so that the core barrel 1 may be located in the middle of the conversion ring beam 22, such as between the core barrel 1 and the conversion ring beam 22 by means of tie beams 23. A plurality of support structures 21 may be distributed around the core barrel 1 (i.e. circumferentially arranged around the core barrel 1) for supporting the transition ring beams 22. A plurality of upper uprights 24 connected at their lower ends to the conversion ring beam 22 may extend upwardly and serve to carry an upper building 30 (shown in fig. 1).

For example, a plurality of support structures 21 may be arranged in the circumferential direction of the conversion ring beam 22, and an upper end of each support structure may be connected with the conversion ring beam 22 to support the conversion ring beam 22. One support structure 21 may include two inclined columns 211, upper ends of the two inclined columns 211 in the same support structure 21 may be connected to the conversion ring beam 22 in a converging manner, upper ends of the two inclined columns 211 have a gap in a circumferential direction of the conversion ring beam 22, and lower ends of the two inclined columns 211 are connected in a converging manner such that each inclined column 211 is arranged obliquely. Two diagonal columns 211, such as in the same support structure 21, may be formed approximately in a V-shaped configuration for supporting the conversion ring beam 22. Wherein, in the embodiments of the present application, the converging connection refers to that two members intersect and are rigidly connected.

In connection with fig. 1 and 2, a plurality of support structures 21 and a core tube 1 at the bottom may be provided as part of the lower building 10, and a conversion ring beam 22 and a pull beam 23 to which the conversion ring beam 22 is connected and a corresponding core tube 1 may be provided as part of the conversion layer 20. Based on this, the remaining upper core barrel 1 and the plurality of upper uprights 24 may be part of an upper building 30. Wherein a lower end of each upper upright 24 may be connected to the conversion ring beam 22, the other end may extend upward, and a plurality of upper uprights 24 may be arranged in a circumferential direction of the conversion ring beam 22. In this way, the vertical loads in the outer frame 2 part of the upper building 30 and the outer frame 2 part of the lower building 10 can be transferred through the transfer ring beam 22, so that the lower ends of the plurality of upper uprights 24 can be flexibly connected to corresponding positions on the transfer ring beam 22 according to design requirements, so as to realize different functional and space design requirements between the upper building 30 and the lower building 10, i.e. to improve the flexibility of the design of the building space in the upper building 30 and the lower building 10.

As shown in fig. 2, a portion of the tension beam 23 may be arranged between the transition ring beam 22 and the core barrel 1. In the partial pull beams 23, one end of one pull beam 23 may be connected to the core tube 1, and the other end of the pull beam 23 may be connected to the conversion ring beam 22, and the connection manner of the two ends of the pull beam 23 may be a converging connection. So that the conversion ring beam 22 can be connected with the core tube 1 by the pull beam 23 under the bearing of the supporting structure 21 and form a stable outer frame 2 structure. In this way, the two diagonal columns 211 in each support structure 21 can carry the vertical (gravitational) load of the building in conjunction with the core barrel 1 in the up-down direction.

Also, since the upper ends of the two diagonal columns 211 in each support structure 21 have a gap, and the lower ends meet in a connected arrangement. So that two diagonal columns 211 in the same supporting structure 21 can approximately form a V-shaped structure, and the two diagonal columns 211 in the V-shape can form an enclosed integral structure with the conversion ring beam 22. Based on this, the plurality of inclined columns 211 which are arranged in an inclined way can also share the horizontal load (such as wind load and earthquake action) of the building, which is beneficial to improving the side rigidity, earthquake resistance and wind resistance of the whole structure of the building.

The lower ends of the two inclined columns 211 in the same supporting structure 21 can be directly connected with a basement structure or a foundation to bear the load of the supporting structure 21, and the whole supporting structure 21 can be approximately in a V-shaped structure, so that the structure is simple.

Further, as shown in fig. 2, a support structure 21 may further include a vertical column 212, and an upper end of the vertical column 212 may be connected to a lower end of two diagonal columns 211 in the support structure 21 in a crossing manner, and a lower end of the vertical column 212 may be directly connected to a basement structure or a foundation, thereby supportingly connecting the two diagonal columns 211. At this time, the two inclined columns 211 and the vertical column 212 may approximately form a Y-shaped structure. In this way, the height of the vertical column 212 in the up-down direction can be adjusted to adjust the positions of the lower end points of the two inclined columns 211, so that the inclined columns 211 which are obliquely arranged are prevented from affecting the use efficiency of the bottom space of the outer frame 2 and the stress load of the outer frame.

The main structure of the core tube 1 may be made of one or more of a steel-concrete structure, a steel structure, and other building materials. Correspondingly, the main structure of the outer frame 2 can also be made of one or more of steel-concrete structure, steel structure and other building materials. The building material of the steel-concrete structure can comprise reinforced concrete, section steel concrete, steel pipe (or steel cylinder) concrete and the like. For example, the core tube 1 may be made of reinforced concrete or steel structure, or may be based on reinforced concrete, and steel concrete or steel structure may be added at corresponding positions to increase the structural strength of the core tube 1. For the outer frame 2, taking the support structure 21 as an example, the diagonal columns 211 in the support structure 21 may be made of reinforced concrete, section steel concrete, steel pipe concrete or steel structure. Correspondingly, the vertical column 212 can also be made of reinforced concrete, section steel concrete, steel pipe concrete or steel structures.

For example, at the front door of the conversion system 100 of the diagonal ring-beam structure, vertical columns 212 may be installed at lower ends of two support structures 21 adjacently arranged, and the heights of the two vertical columns 212 may be made not lower than the height of the front door. Thereby avoiding the obliquely arranged diagonal columns 211 occupying the lateral space at the bottom of the conversion system 100 of the diagonal bracing ring-beam structure. Furthermore, a vertical column 212 may also be mounted below the two diagonal columns 211 in each support structure 21 for supporting the two diagonal columns 211. That is, in the embodiment of the present application, each supporting structure 21 for carrying the conversion ring beam 22 may be approximately a V-shaped structure, or may be approximately a Y-shaped structure, and under the condition that the supporting structure 21 is not affected to share the vertical load and the horizontal load, part or all of the supporting structure 21 may be flexibly adjusted according to design criteria and appearance requirements.

In the conversion system 100 of the diagonal bracing ring beam structure provided in the embodiment of the present application, the conversion ring beam 22 may be approximately a circular ring structure or an elliptical ring structure. Compared with other rectangular or polygonal structures, the conversion ring beam 22 with the circular or elliptical ring structure has better self-balancing stress characteristics, and is beneficial to improving the structural integrity and stability.

For example, as shown in fig. 2, a plurality of support structures 21 may be sequentially arranged in the circumferential direction of the conversion ring beam 22 and connected to the conversion ring beam 22. Such as the upper end of one of the diagonal columns 211 may meet the upper end of an adjacent one of the diagonal columns 211 in the adjacent support structure 21. Since the upper ends of the two diagonal columns 211 are connected to the same position of the conversion ring beam 22 in an intersecting manner, the bearing capacity of the gravity load of the conversion ring beam 22 is improved. Based on this, the upper ends of two diagonal columns 211 adjacent to each other in the partially adjacent two support structures 21 can be joined together in the circumferential direction of the conversion ring beam 22. It may also be possible to connect each support structure 21 with two adjacent support structures 21 in contact along the circumferential direction of the conversion ring beam 22, that is, the upper ends of two diagonal columns 211 that are close to each other in each two adjacent support structures 21 may be connected to the same position of the conversion ring beam 22 in a converging manner.

Illustratively, around the circumference of the conversion ring beam 22 in a clockwise direction, the upper end of the first diagonal column 211 is in intersection with the upper end of the second diagonal column 211, the lower end of the second diagonal column 211 is in intersection with the lower end of the third diagonal column 211, the upper end of the third diagonal column 211 is in intersection with the upper end of the fourth diagonal column 211, and the lower end of the last diagonal column 211 is in intersection with the lower end of the first diagonal column 211, … …. In this way, by the intersecting connection of the plurality (generally even number) of diagonal columns 211, while the vertical load of the conversion ring beam 22 is carried, due to the plurality of diagonal columns 211 which are inclined and arranged in an intersecting manner end to end, the plurality of diagonal columns 211 can also load and balance the horizontal load of themselves and the partial horizontal load transmitted by the conversion ring beam 22, which is beneficial to improving the capability of the outer frame 2 against the horizontal load.

Referring to fig. 2, in the circumferential direction of the conversion ring beam 22, the upper ends of two diagonal columns 211 adjacent to each other in two adjacent support structures 21 are converged and connected at the same position of the conversion ring beam 22, which can be used as a stress node of the outer frame 2. Based on this, the lower end of one upper upright 24 can be simultaneously intersected with the upper ends of the two inclined columns 211, so that the two inclined columns 211 in the inverted V shape can jointly support one upper upright 24, which is beneficial to directly transmitting the vertical load at the upper upright 24. Based on this, the upper ends of each two diagonal columns 211, which are connected by the upper ends in a converging manner, can be connected by the upper column 24 in a converging manner, so that the vertical load transmission of the upper column 24 is more direct. In addition, the end of one tie beam 23 far from the core tube 1 may be simultaneously connected with the upper ends of the two inclined columns 211 and the lower ends of the corresponding one upper upright column 24. That is, the conversion ring beam 22 can connect two inclined columns 211, an upper upright column 24 and a pull beam 23 at the same time to serve as a stress center node of the outer frame 2, which is beneficial to balancing the gravity load and the horizontal load in the outer frame 2, leading the force to be directly transferred, and improving the integrity of the outer frame 2.

Alternatively, on the premise that the upper ends of two adjacent diagonal columns 211 in two adjacent support structures 21 are in intersection connection, the upper ends of the two diagonal columns 211 are only in intersection connection with the lower end of one upper upright column 24 at the same position of the conversion ring beam 22, so that the vertical load of the upper upright column 24 can be directly transmitted. The upper ends of the two diagonal columns 211 may be connected to the same position of the conversion ring beam 22 only with one end of one tie beam 23 away from the core tube.

Furthermore, the upper uprights 24 may also be arranged at other positions of the conversion ring beam 22. As shown in fig. 2, the lower end of at least one upper upright 24 and the conversion ring beam 22 may be joined between two adjacent diagonal columns 211 in the circumferential direction of the conversion ring beam 22. Taking the number of the upper upright posts 24 connected between the two inclined posts 211 as an example, the lower end of the upper upright post 24 can be connected with the core barrel 1 through a pull beam 23, which is beneficial to flexible arrangement of the upper upright posts 24.

Thus, in the present embodiment, part or all of the lower ends of the upper uprights 24 can be joined at the two diagonal uprights 211 of the upper end junction to increase the vertical load of each upper upright 24. In addition, in order to facilitate the flexible arrangement of the upper upright 24, a portion of the upper upright 24 may be connected to the conversion ring beam 22 between two adjacent diagonal columns 211 in a converging manner, where, for the plurality of pull beams 23 at the conversion layer 20, one end of each pull beam 23, which is far away from the core tube 1, may be connected to the conversion ring beam 22 in a converging manner with the upper end of at least one diagonal column 211, may be connected to the conversion ring beam 22 in a converging manner with the lower end of one upper upright 24, and may also be connected to the conversion ring beam 22 in a converging manner with the lower end of one upper upright 24 and the upper ends of two diagonal columns 211 at the same time, so as to form a stress node, which is not limited.

In other embodiments, the upper ends of two diagonal columns 211 adjacent to each other in two support structures 21 partially adjacent to each other may be provided with a gap along the circumferential direction of the conversion ring beam 22. At this time, in order to make the whole of the outer frame 2 cooperatively stressed, an upper upright column 24 and a pull beam 23 may be connected at the position of the transition ring beam 22 between the upper ends of the two diagonal columns 211, which is beneficial to the coordination of the whole of the outer frame 2, thereby improving the stability of the whole structure of the outer frame 2.

In some embodiments, as shown in fig. 3, fig. 3 is a top view over the conversion layer 20 shown in fig. 1. The conversion layer 20 may consist of a part of the core tube 1 and a part of the outer frame 2 between the upper building 30 and the lower building 10, also being part of the conversion system 100 of the diagonal ring beam structure. At this time, the cross section (i.e., cross section) of the core tube 1 in the direction perpendicular to the vertical direction may be approximately rectangular or square in shape, i.e., the core tube 1 includes two outer walls 11 extending in the left-right direction and two outer walls 11 extending in the front-rear direction, and the main bodies of the four outer walls 11 are shear wall structures and may be connected end-to-end in sequence in the circumferential direction of the core tube to form the main body structure of the core tube 1. The core tube 1 may further include a plurality of inner walls 12 and a plurality of inner beams 13 between the plurality of outer walls 11, and at least two outer walls 11 may be connected through the inner walls 12 and/or the inner beams 13 to improve overall stability between the plurality of outer walls 11. For example, the inner space of the core tube 1 surrounded by the four outer walls 11 may be correspondingly isolated by the connection arrangement of the plurality of inner walls 12, thereby separating a plurality of smaller building spaces, and when communicating with adjacent small building spaces, a door opening or window opening between two adjacent small building spaces may be formed by arranging the inner beam 13 between the inner walls 12 or between the inner walls 12 and the outer walls 11. The outer wall 11 may be connected with the inner wall 12 and/or the inner beam 13 in a crossing manner to form a crossing point of the core tube 1, so as to improve the overall stability of the core tube 1.

Based on this, referring to fig. 3, for the tie beam 23 between the conversion ring beam 22 and the core tube 1, the end of the tie beam 23 far from the core tube 1 is connected to the conversion ring beam 22, and when the end of the tie beam 23 near to the core tube 1 is taken as an example of the inner end of the tie beam 23, the inner end of the tie beam 23 is connected to the core tube 1, the inner end of the tie beam 23 may be connected to the junction of two adjacent outer walls 11 (i.e. a junction point may also be formed between two adjacent outer walls 11), so that two adjacent outer walls 11 connected to the tie beam 23 may be connected to the outer frame 2 through the tie beam 23 to form an integral structure, for example, the load transferred via the tie beam 23 may be simultaneously guided to the two adjacent outer walls 11 at the junction point of the inner end of the tie beam 23 and the two adjacent outer walls 11, which is beneficial to improve the overall stability and coordination of the conversion system 100 of the diagonal bracing ring beam structure.

Furthermore, on each outer wall 11 of the core tube 1, a plurality of junction points with the inner wall 12 or the inner beam 13 are provided. In this way, the inner ends of the partial bracing beams 23 can be connected to the junction of the partial bracing beams, so that the structures such as the inner wall 12 or the inner beam 13 of the core tube 1 can bear or transmit horizontal force, which is also beneficial to improving the stability and coordination of the conversion system 100 of the diagonal bracing ring beam structure, and the arrangement of the bracing beams 23 can be more flexible.

It should be noted that, in the embodiment of the present application, the cross section of the core tube 1 may also be a polygonal structure such as a triangle, a pentagon, or a hexagon, and the number of the outer walls 11 may correspond to the shape of the cross section, for example, the number of the outer walls 11 corresponding to the cross section of the triangle may be three, and the number of the outer walls 11 winning the cross section of the hexagon may be six, so as to connect the inner end of the pull beam 23 with the junction point of the core tube 1. In addition, the cross section of the core tube 1 may be approximately circular or elliptical, and in this case, when the tie beams 23 are connected, the inner ends of the tie beams 23 may be connected to the junction points of the outer wall 11 and the inner wall 12 or the inner beam 13.

Illustratively, taking the example that the cross section of the core tube 1 is rectangular, the number of the outer walls 11 of the core tube 1 may be four. And the number of support structures 21 may be greater than or equal to three. In connection with fig. 2, taking an example in which the number of the supporting structures 21 is six, two tie beams 23 may be respectively arranged at four corners of the core tube 1 of a rectangular structure (i.e., at the intersection of two adjacent outer walls).
