Technical Field

The utility model relates to the technical field of building structure engineering, in particular to a conversion system of a diagonal brace and a core tube.

Background

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 the modeling of building elevation is diversified. Because of the different requirements of the upper and lower parts of the high-rise building on the use function and space, the outer frame column of the upper storey cannot directly and continuously run through and land, and a conversion structure is required to be arranged for conversion connection of the upper outer frame column and the lower outer frame column. Different building elevation shapes and different internal space effects are matched with the corresponding conversion structural forms, and the conversion structural forms are required to be innovated and developed to meet the requirements of building engineering. Currently, for high-rise buildings adopting a frame core tube structure system, when the lower outer frame column is of a diagonal bracing structure, no perfect solution exists for the conversion support of the upper outer frame column.

Disclosure of Invention

The embodiment of the application provides a conversion system of diagonal bracing and a core tube, and aims to provide a building conversion system with an upper outer frame column as a stand column and a lower outer frame column as a diagonal bracing structure.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

some embodiments of the present application provide a conversion system of a diagonal brace and a core tube, including a core tube, a plurality of diagonal brace structures, a plurality of first tie beams, a plurality of upper upright posts, and a plurality of frame beams. Wherein, a plurality of bracing structures are arranged in proper order around the core section of thick bamboo, and a bracing structure includes two batter posts, and the lower extreme of two batter posts in the same bracing structure is crossed and is connected, and the upper end of these two batter posts has the clearance, and the batter post is made by reinforced concrete structure or steel construction. A plurality of first tie beams are disposed between the core barrel and the diagonal bracing structure. The upper end of one diagonal column is in intersection connection with the upper end of an adjacent diagonal column in an adjacent diagonal strut structure, and forms a first node. Each first node is connected with the core tube through at least one first pull beam. The plurality of upper uprights are arranged in one-to-one correspondence with the first nodes, the lower end of one upper upright being in a junction with one first node, so that two diagonal uprights at the first node support the upper upright. The frame beam is a polygonal enclosing structure and comprises a plurality of beam sections which are sequentially connected end to end. The number of the beam sections corresponds to the number of the first nodes one by one, and two ends of one beam section are connected with two adjacent first nodes in a converging mode.

Therefore, in the conversion system of the diagonal brace and the core tube provided in the embodiment of the application, since the lower ends of the two diagonal columns in each diagonal brace structure are in intersection connection, the upper ends of the two diagonal columns can be respectively in intersection connection with the upper ends of the two diagonal columns close to each other in the two adjacent diagonal brace structures, and two first nodes are formed.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; the term "fixed" is also to be understood in a broad sense, and the specific meaning of the term in this application is understood to be specifically understood by those of ordinary skill in the art.

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 the space requirement, the outer frame column of the upper storey cannot directly and continuously run through and land, and a conversion layer is required to be arranged for conversion connection between the upper outer frame column and the lower outer frame column.

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. For high-rise buildings adopting a framework core tube system, when the lower outer frame column is of a diagonal bracing structure, no perfect solution exists for the conversion support of the upper outer frame column. Based on this, as shown in fig. 1, the present embodiment provides a conversion system 100 of a diagonal brace and a core tube, and the conversion system 100 of a diagonal brace and a core tube may include a core tube 10, a plurality of diagonal brace structures 20, a plurality of first tie bars 30, a plurality of upper columns 40, and a frame bar 50.

The number of the core tubes 10 may be one, or may be two, three, or more. Taking the example that the number of core barrels 10 is two, the two core barrels 10 may be located in the middle region of the frame beam 50 and sequentially arranged with a gap between the two core barrels 10. The arrangement direction of the two core barrels 10 that are sequentially arranged may be a straight line direction or may have a certain included angle, which is not limited in this application. In the embodiment of the present application, the middle area refers to an inner area surrounded by the enclosed structure, and not refers to the middle position of the inner area.

With continued reference to fig. 1, the plurality of diagonal strut structures 20 may be centered about the two core barrels 10 and sequentially disposed about the two core barrels 10 such that the two core barrels 10 are also within a central region of the plurality of diagonal strut structures 20. For example, one diagonal brace member 20 may include two diagonal braces 21, lower ends of the two diagonal braces 21 in the same diagonal brace member 20 may be connected in a converging manner, and upper ends of the two diagonal braces 21 have a gap. So that two diagonal columns 21 in the same diagonal bracing structure 20 can approximately form a V-shaped structure, namely a lower outer frame column structure which is obliquely arranged.

As shown in fig. 1, a plurality of first tension beams 30 may be arranged between the core tube 10 and the diagonal bracing structure 20. Since the upper end of one diagonal strut 21 may be in a converging connection with the upper end of an adjacent diagonal strut structure, and form a first node 22, wherein a converging connection refers to the intersection and rigid connection of two members. Thus, at least one first pull beam 30 may be connected at each first node 22, with the end of the first pull beam 30 remote from the first node 22 being connected to the core barrel 10. For example, the first node 22 may be connected to a core barrel 10 by a first pull beam 30. It is also possible to connect the first node 22 with different locations of the same core barrel 10 via two or more first tension beams 30 so that the core barrel 10 may be dispersed to bear the tension forces at the first node 22. In addition, the first node 22 may be connected to a plurality of adjacently disposed core barrels 10 through a plurality of first tie beams 30 to distribute the tensile force at the first node 22 to the connected plurality of core barrels 10.

Based on this, since the lower ends of the two diagonal columns 21 in each diagonal brace structure 20 are intersected, and the upper ends of the two diagonal columns 21 may be respectively intersected with the upper ends of the two diagonal columns 21 adjacent to each other in the two adjacent diagonal brace structures 20, and two first nodes 22 are formed. The upper ends of the two diagonal columns 21 in one of the diagonal strut structures 20 are extended upward in the left-right direction, respectively, taking the example that the upper ends of the two diagonal columns 21 have a gap. The upper end of the right diagonal strut 21 may meet the upper end of the adjacent diagonal strut 21 of the right adjacent diagonal strut 20 and form a first node 22. The upper end of the left diagonal strut 21 may meet the upper end of the adjacent diagonal strut 21 of the left adjacent diagonal strut 20 and form a first node 22. In this manner, the plurality of diagonal strut structures 20 may be arranged continuously around the core barrel 10 and may be connected end to form a containment structure such that the number of first nodes 22 corresponds one-to-one to the number of diagonal strut structures 20. And may be connected by first tie beams 30 that meet at each first node 22 so that a plurality of diagonal strut structures 20 may be connected with the core barrel 10 to form an integral lower spatial structure for supporting an superstructure.

With continued reference to fig. 1, taking the example of a building having a plurality of upper columns 40 as the upper frame columns, the number of upper columns 40 and the number of diagonal strut structures 20 may be equal and arranged in a one-to-one correspondence when the upper columns 40 and diagonal strut structures 20 are switchably connected. That is, the lower end of one upper column 40 may be connected to a first node 22 such that the two diagonal columns 21 at the first node 22 may together support the connected upper column 40, making the gravitational load (i.e., vertical load) transfer of the upper column 40 more direct. In this manner, the upper end of the upper column 40 may extend upwardly and may be coupled to the core barrel 10 in cooperation with a tension beam above the first node 22 for carrying the upper floors of the building. In this way, a portion of the gravitational load of the building may be carried by the core barrel 10, while each upper column 40 may transfer another portion of the gravitational load via the connected first node 22 to two diagonal columns 21 at that first node 22, such that the diagonal columns 21 of the plurality of diagonal strut structures 20 directly carry the gravitational load of the building. Moreover, the two diagonal columns 21 of the diagonal bracing structure 20 can also bear horizontal loads (such as wind loads and earthquake actions) of the building (i.e. at the first node 22), which is beneficial to improving the overall structure lateral stiffness of the building and the earthquake and wind resistance.

Wherein the lower ends of the same diagonal brace member 20 may be connected to the basement or foundation structure such that the basement or foundation structure carries the load of the diagonal brace member 20. In this case, the whole diagonal brace structure 20 may be approximately V-shaped, and the structure is simple.

Illustratively, as shown in fig. 1, taking an example in which the number of core barrels 10 is two, when a plurality of diagonal bracing structures 20 are arranged, the diagonal bracing structures 20 connected end to end may be arranged in sequence around the two core barrels 10 in the clockwise direction. Taking the example that one diagonal brace structure 20 at the leftmost lower part in fig. 1 is the first diagonal brace structure 20, the lower end of the first diagonal column 21 at the front and the lower end of the second diagonal column 21 at the rear can be intersected and connected to the basement structure or foundation. The upper end of the second diagonal member 21 is joined to the upper end of the third diagonal member 21 and forms a first node 22. The lower end of the third diagonal column 21 is connected with the lower end of the fourth diagonal column 21 in a converging manner, and the upper end of the last diagonal column 21 of … … is connected with the upper end of the first diagonal column 21 in a converging manner, and forms the last first node 22. As such, by the intersection of the upper and lower ends of the plurality (even) of diagonal columns 21, while the first node 22 is formed to carry the gravitational load of the upper column 40, the lower ends of the plurality of diagonal columns 21, which are arranged as being inclined and converging end to end, are also intersected with the basement structure or foundation to form a stable V-shaped or inverted V-shaped space structure for carrying the horizontal load at the first node 22 while supporting the upper column 40.

It should be noted that, for the two diagonal columns 21 in the same first node 22, since the lower ends of the two diagonal columns 21 form a stable triangular structure by the basement structure or foundation which is connected by the intersection. However, for the two diagonal columns 21 in the same diagonal strut structure 20, the two diagonal columns 21 are formed in a stable inverted triangle structure. As shown in fig. 1, the frame beam 50 may include a plurality of beam segments 51, and the plurality of beam segments 51 may be connected end to end in sequence to form a polygonal enclosure. The number of beam segments 51 corresponds to the number of first nodes 22 one by one, and two ends of one beam segment 51 may be connected to two adjacent first nodes 22 in a converging manner. For example, two ends 51 of one beam section may be disposed between two diagonal columns 21 in the same diagonal brace member 20, such that one end of the beam section 51 intersects the upper end of one of the diagonal columns 21 at a first node 22, and the other end of the beam section 51 intersects the upper end of the other diagonal column 21 at the first node 22. In this way, the two diagonal columns 21 of the V-shaped structure may form a stable inverted triangle structure through one cross beam section 51 that is connected in a converging manner, so as to improve the stability of the diagonal strut structure 20 corresponding to the two diagonal columns 21.

In this case, two beam sections 51, one upper column 40, two diagonal columns 21 and at least a first tie 30 can be connected together at the first node 22. The first node 22 may be used as a force node for an external frame structure in a building. Gravity load transfer is made direct by the direct convergence of the upper upright 40 with the two connected diagonal columns 21. While the two diagonal columns 21 and the at least one first tie 30 and the two converging beam sections 51 at the first node 22 can balance the horizontal load generated by the gravity load of the upper upright 40, ensuring the integrity and stability of the conversion structure.

In the case where the number of core barrels 10 is plural, the plural core barrels 10 located in the middle region of the frame beam 50 may be sequentially distributed in one straight line or curved line direction. In addition, taking the example that the number of the core barrels 10 is three or more, the three core barrels 10 may be arranged in a finished product font structure. If the number of the core barrels 10 is four, the four core barrels 10 may be arranged in a zigzag structure.

Illustratively, as shown in fig. 1, in the middle region of the frame beam 50, there is a gap between two adjacent core barrels 10. Based on this, in order to connect and transfer loads between the plurality of core barrels 10, the diagonal brace and core barrel conversion system 100 may further include a plurality of second tie bars 60, and two adjacent core barrels 10 may be connected by the plurality of second tie bars 60, so that loads (particularly horizontal loads) between two adjacent core barrels 10 may be transferred by the plurality of tie bars 60. In this way, by the arrangement of the plurality of second tie beams 60, a plurality of core barrels 10 that are distributed and arranged may be connected together to achieve self-balancing of the horizontal load.

In some embodiments, as shown in fig. 2, fig. 2 is a top view of the conversion system 100 of the diagonal braces and core tube shown in fig. 1. Taking the plane in which the lower ends of the plurality of diagonal columns 21 are located as an example of a reference plane, the reference plane is generally perpendicular to the vertical direction, that is, parallel to the horizontal plane. In the vertical direction, the vertical projection of the frame beam 50 on the reference plane is defined as a reference projection area. When the diagonal bracing structure 20 is arranged, the lower ends of some or all of the diagonal bracing structures 20 may be overlapped with the reference projection area, as in the arrangement of the diagonal bracing structures 20 and the frame beams 50 on the left and right sides and the front side in fig. 2, that is, each diagonal column 21 may be arranged in one of the vertical planes. Alternatively, part or all of the lower ends of the diagonal strut structures 20 may be positioned on the side of the reference projection area away from the core barrel 10, as in the arrangement of the diagonal strut structures 20 and the frame beams 50 on the rear side in fig. 2, that is, each diagonal strut 21 may be arranged obliquely from bottom to top in a direction approaching the core barrel 10. Alternatively, the lower ends of some or all of the diagonal strut structures 20 may be positioned on the side of the reference projection area close to the core tube 10, i.e., each diagonal strut 21 may be disposed obliquely from bottom to top in a direction away from the core tube 10.

The three arrangements of the diagonal brace structure 20 may be used independently in the same diagonal brace and core tube conversion system 100, and may be used in combination with each other. Such as two adjacent diagonal strut structures 20. For two diagonal columns 21 in the same diagonal bracing structure 20, one of the diagonal columns 21 may be arranged along one of the vertical planes, and the other diagonal column 21 may be arranged from bottom to top close to or away from the core tube 10. The arrangement may be selected in different ways according to load requirements and modeling requirements, which is not limited in this application.

When the diagonal column 21 is disposed from bottom to top near or far from the core tube 10, the diagonal column 21 generates horizontal force (horizontal force in the in-plane and out-of-plane directions of the V-shaped diagonal strut structure 20) under the action of gravity load, and the horizontal thrust force at the corner is the largest. Based on this, in the case where the upper and lower ends of the plurality of diagonal columns are connected end to end and are joined into one integral frame structure by the plurality of beam sections 51, a part of the in-plane horizontal force of the V-shaped diagonal strut structure can be parallel. In addition, the arrangement of the plurality of first pull beams 30 connected in a converging manner between the core tube 10 and the diagonal bracing structure 20 may be matched with the core tube 10, so that the frame structure formed by the plurality of diagonal bracing structures 20 is connected with the core tube 10 and used for parallel remaining horizontal forces, thereby realizing the self-balancing of the horizontal forces under the action of gravity load. The axial force borne by the first pull beam 30 between the core tube 10 and the first node 22 may be a tensile force or a compressive force, which only needs to meet the design requirement, which is not limited in this application.

Based on this, with respect to upper column 40, upper column 40 may be extended in the vertical direction when upper column 40 extending upward is arranged. It is also possible to have the extension direction of upper column 40 be angled with respect to the vertical (i.e., an oblique arrangement). In the case where the upper column 40 is disposed obliquely, if the building floor of the diagonal brace-core tube conversion system 100 is higher, that is, the height of the upper column 40 is larger, the angle of inclination of the upper column 40 may be adjusted to be smaller. Correspondingly, if the height of upper column 40 is smaller, upper column 40 may be flexibly selected over a larger range of tilt angles. Wherein, for the tilting direction of the upper upright 40, the upper upright 40 can be arranged obliquely leftwards, rightwards, forwards and backwards or in 360 degrees according to the design requirement when being arranged. The present application is not limited in this regard.

Taking the frame beams 50, the first nodes 22 and the first tie beams 30 as examples, the floor is a transfer floor. Above the conversion layer, the upper columns 40 may also be connected to the core tube 10 in the height direction thereof by a tie beam structure, and two adjacent upper columns 40 may also be connected by a cross beam.

In some embodiments, with continued reference to fig. 2, the cross-sectional view of the core barrel 10 in a plane perpendicular to the vertical plane may be a polygonal structure. The core barrel 10 may include a plurality of outer walls 11, a plurality of inner walls 12, and a plurality of inner beams 13. The plurality of outer walls 11 may be connected end to end in sequence and form the main body of the core barrel 10 in a corresponding polygonal structure. Wherein a plurality of inner walls 12 and inner beams 13 may be arranged between a plurality of outer walls 11. And at least two outer walls 11 may be connected by an inner wall 12 and/or an inner beam 13 to improve overall stability between the plurality of outer walls 11.

For example, the inner space of the rectangular core tube 10 surrounded by the four outer walls 11 may be connected and arranged by a plurality of inner walls 12 to be correspondingly isolated, thereby separating a plurality of smaller building spaces. When communicating adjacent small building spaces, a door opening, or window opening, between two adjacent small building spaces may be formed by disposing 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 improve the overall stability of the core barrel 1. In addition, two adjacent external walls 11 may also be connected by a junction, and form a third node 15.

Illustratively, as shown in FIG. 2, one exterior wall 11 may be connected with one interior wall 12 and form one second node 14, and the other end of the interior wall 12 may also be connected with another exterior wall 11 and form another second node 14. Alternatively, if the second node 14 is required to be disposed at a position where the inner wall 12 cannot be disposed for separating the building space, one inner beam 13 may be connected to one outer wall 11 at the position in a crossing manner to form one second node 14, and the other end of the inner beam 13 may be connected to the other outer wall 11 to form the other second node 14. Alternatively, the other end of the inner beam 13 may be connected to one end of an inner wall 12, and the other end of the inner wall 12 may be connected to an outer wall 11 in a converging manner, and form a second node 14.

Based on this, between two adjacent core barrels 10, as shown in fig. 2, both ends of one second pull beam 60 may be connected to the third nodes 15 on the two core barrels 10. Alternatively, the two ends of the second pull beam 60 may be connected to the second nodes 14 on the two core barrels 10. Alternatively, one end of the second pull beam 60 may be connected to the second node 14 of one of the core barrels 10, and the other end of the second pull beam 60 may be connected to the third node 15 of the other core barrel 10. Among them, the arrangement of part or all of the second tension beams 60 can be flexibly selected among the above-described several modes.

Further, when the first pull beam 30 is arranged, since the end of the first pull beam 30 remote from the connected one core barrel 10 is connected to the first node 22. The other end of the first tie beam 30 may be connected to the second node 14 of the core tube 10, or may be connected to the third node 15 of the core tube 10. Can be flexibly selected according to the requirements.

The second node 14 and the third node 15 are described. Taking the third node 15 as an example, since the outer wall 11 is a structure extending from bottom to top, that is, the first node 15 is a continuous structure extending from bottom to top. Taking the second node 14 as an example, if the second node 14 is formed by intersecting the inner wall 12 and the outer wall 11, the second node 14 may also be regarded as a continuous structure from bottom to top. If the second node 14 is formed by the intersection of the inner beam 13 and the outer wall, the second node 14 may be regarded as approximately a punctiform structure. The present application is not limited in this regard.

Based on this, when the load is transmitted through the first tension beam 30 around the core tube 10. Taking the example that the first tie beam 30 is connected to one of the third nodes 15, the load can be transferred to the adjacent two outer walls 11 through the third node 15. Taking the example where the first tie beam 30 is connected to one of the second nodes 14, the load may be transferred from that second node 14 via the inner wall 12 and/or the inner beam 13 so that both outer walls 11 may take up the load transferred by the first tie beam 30. Based on this, for the load transferred to the core tube 10 through the first pull beam 30 and the second pull beam 60, the load can be transferred to the plurality of outer walls 11 through the second node 14 and the third node 15, so that the load can be shared and self-balanced by the overall structure of the core tube 10, which is beneficial to improving the overall stability of the conversion system.

In some embodiments, as shown in fig. 1, when the diagonal brace structure 20 is stably connected to the core barrel 10, the switching system 100 of the diagonal brace and the core barrel may further include a plurality of third pull beams 70, and a portion of the cross beam section 51 may be connected to one end of at least two third pull beams 70 in a crossing manner and form a fourth node 52. The other ends of the two third tie beams 70 may be connected to different positions of the same core tube 10, or may be connected to two core tubes 10, and based on this, a plurality of horizontal triangle structures may be formed by connecting a plurality of first tie beams 30 and a plurality of third tie beams 70 between the frame beam 50 and at least one core tube 10. Since the triangle is the most stable component shape, the connection between the core tube 10 and the plurality of diagonal strut structures 20 is facilitated to increase the integrity and stability of the connection between the core tube and the plurality of diagonal strut structures 50 by forming a plurality of triangle structures between the core tube 10 and the frame beams 50.

In the beam section 51 provided with the fourth node 52, the fourth node 52 may be located between two adjacent first nodes 22. The end of the third pull beam 70 near the core barrel 10 may meet at the second node 14 or the third node 15 of the core barrel 10.

Taking at least the diagonal bracing structure 20, the first tie 30, the upper upright 40 and the frame 50 as an example, in the horizontal direction, a plurality of corner structures are provided on the outer frame corresponding to the third nodes 15 on the outer sides of the core tube 10. Illustratively, as shown in FIG. 2, the diagonal brace and core barrel conversion system 100 also includes corner structures 80. In case the two adjacent beam sections 51 have a larger inner bend angle towards the core barrel 10, the two beam sections 51 and the two connected diagonal strut structures 20 (or diagonal struts 21) may be seen as part of the corner structure 80. At least one corner structure 80 may be correspondingly arranged with an outer third node 15, the first node 22 at the corner structure 80 and the third node 15 may be connected by a first tie beam 30. Due to the shaping of the outer frame, a large horizontal pushing force is provided at the corner structure 80, so that the first pull beam 30 between the corner structure 80 and the core barrel 10 will bear a large axial pulling force. Based on this, when the first tie beam 30 is disposed, the cross-sectional area of the first tie beam 30 may be increased, and the first tie beam 30 may be made of a material having a higher tensile strength.

For example, the first tie beam 30 between the corner structure 80 and the third node 15 may be made of a steel-concrete structure or a steel structure, or the first tie beam 30 may be made of a concrete member with a high reinforcing steel bar reinforcing rate, so that the tensile capacities of the core tube 10 and the corner structure 80 may be improved.

In some embodiments, the main structure of the core tube 10 may be made of one or more of reinforced concrete, and steel construction materials. Correspondingly, the main structures of the second tie beam 60 and the outer frame (in which case the outer frame may include the third tie beam 70) may also be made of one or more of steel concrete structures, steel structures, 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. Taking the diagonal bracing structure 20 as an example, the diagonal columns 21 in the diagonal bracing structure 20 may be made of reinforced concrete, section steel concrete, steel pipe concrete, steel structures or the like.

For the core tube 1, it may be made of reinforced concrete or steel structure, or may be made of reinforced concrete, or a skeleton such as steel may be added at a corresponding position to increase the structural strength of the core tube 1. For example, a large horizontal load needs to be transferred between the plurality of first nodes 22 at the switching layer and the core barrel 10. In this way, if the core tube 10 is based on reinforced concrete, the steel content of the horizontal steel bars or the frameworks such as the steel sections in the outer wall 11 at a height near the conversion layer can be increased, so as to increase the horizontal tensile properties of this portion of the outer wall 11, thereby greatly increasing the structural strength and tensile properties of the third node 15. In addition, between two adjacent second nodes 14, the steel content of the inner wall 12 or the horizontal steel bars or steel bars and other frameworks in the inner beam 13 can be increased, so as to improve the horizontal tensile property of the inner wall 12 or the inner beam 13 at the part, and increase the structural strength and the tensile property at the second nodes 14.

The reinforcing members of the outer wall 11, the inner wall 12, and the inner beam 13 may be disposed only near the conversion layer, or the second node 14 and the third node 15 having high structural strength may be disposed at appropriate positions of the core tube 10 in the up-down direction. It is only necessary that the portion of the second node 14 or the third node 15 can be connected with the first pull beam 30, the second pull beam 60 or the third pull beam 70 in a converging manner, so that the horizontal load transmitted through the first pull beam 30 and the third pull beam 70 can be transmitted to the integral structure of one or more core barrels 10 through the reinforcing member, thereby realizing the self-balancing of the horizontal force of the conversion layer and improving the structural integrity.

In the embodiment of the present application, the outer third node 15 on the core tube 10 corresponding to the corner structure 80 is described. If the number of core barrels 10 is one, the cross section is a polygonal structure of the core barrels 10, and the third nodes 15 on the outer side may make part or all of the third nodes 15. If the number of the core barrels 10 is plural, the third node 15 close to the other core barrels 10 in one core barrel 10 is the inner third node, and the third node 15 far from the other core barrels 10 is the outer third node.

In some embodiments, as shown in fig. 3, fig. 3 is a schematic perspective view of the core barrel 10 shown in fig. 1 near the transition layer. The core barrel 10 may further comprise a structural beam 16, which structural beam 16 may be arranged close to the transition layer in the up-down direction, i.e. the structural beam 16 may be arranged at the same level as the first node 22. Between two adjacent third nodes 15, connection may also be performed through a structural beam 16, for example, one end of the structural beam 16 may be connected with one of the third nodes 15 in a crossing manner, and the other end of the structural beam 16 may be connected with the other third node 15 in a crossing manner. By the arrangement of the structural beams 16, the load carrying capacity between the two third nodes 15 can be enhanced, thereby greatly increasing the horizontal tensile load carrying capacity of the core barrel 10 at the height position of the conversion layer. In this way, the first pull beam 30, the second pull beam 60, and the third pull beam 70 cooperatively connected at the third node 15 may transfer a horizontal load to the overall structure of the one or more core barrels 10, so as to achieve self-balancing of horizontal forces of the conversion layer and improve structural integrity.

With continued reference to fig. 3, the structural beam 16 may also be disposed on the interior wall 12 at the transition layer, i.e., two adjacent second nodes 14 may also be connected by the structural beam 16, e.g., one end of the structural beam 16 may be connected with one of the second nodes 14 and the other end of the structural beam 16 may be connected with the other second node 14. In this way, when the core tube 10 is arranged, the two ends of the structural beam 16 can be used to connect the first pull beam 30, the second pull beam 60 or the third pull beam 70, and the horizontal tensile load capacity of the core tube 10 at the height position of the conversion layer can be improved.

When the structural beams 16 are arranged, the structural beams 16 may be steel reinforced concrete members, steel structures or reinforced concrete members with higher reinforcement ratio, and have higher tensile properties. The structural beams 16 disposed between adjacent two third nodes 15 may be covered by the exterior wall 11. Correspondingly, the structural beams 16 disposed between two adjacent second nodes 14 may also be covered by the inner wall 12 to avoid affecting the interior space effect of the building. In addition, when a larger horizontal load exists between two adjacent second nodes 14 or third nodes 15, the cross-sectional size of the structural beam 16 can be correspondingly increased, and even part of the structural beam 16 can be exposed, so that the reliable transmission of the horizontal load is ensured, and the horizontal force self-balancing of the conversion layer is realized. The present application is not limited in this regard.

In addition, the structural beams 16 may be disposed at other height positions of the core barrel 10. When two core barrels 10 adjacently arranged are connected by the second pull beam 60, since the second pull beam 60 is not only arranged at the height position of the conversion layer, the core barrels 10 are also connected with a plurality of second pull beams 60 at other height positions, which also transmits a large horizontal load. Based on this, the above-described structural beams 16 may be arranged at the second node 14 and/or the third node 15 at other height positions of the core tube 10 for the junction connection of the second pull beam 60.

In some embodiments, the diagonal brace and core barrel conversion system 100 may further include a conversion layer floor that may cover the connection frame beams 50 and the plurality of first pull beams 30 in the case where there is only one core barrel 10, and may also be connected to the core barrel 10. In this manner, by the arrangement of the conversion floor, the conversion floor can also transmit horizontal forces between the core barrel 10 and the diagonal bracing structure 20 (and the upper column 40). In addition, if the number of the core barrels 10 is plural, the conversion layer floor slab may also be covered and connected with plural second pull beams so as to balance the horizontal load between two adjacent core barrels 10.

In other embodiments, below the conversion level, the outer frame may be arranged by a lower frame beam, lower floor slab and part of the tie beam to form one or more layers of lower building space, by means of a plurality of bracing structures 20 and supporting connections of the core tube 10, in order to expand the multi-storey building space. Correspondingly, above the conversion layer, the outer frame is arranged to form one or more layers of upper building space through the upper frame beams, the upper floor slab and part of the pull beams by the supporting connection of a plurality of upper upright posts 40 and the core tube 10, and the building area of the diagonal bracing conversion system can be expanded.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions easily conceivable by those skilled in the art within the technical scope of the present application should be covered in the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
