Description

Technical Field

[0001] The present invention relates to the technical field of building structure engineering, and in particular to a conversion system of diagonal braces and core tubes. Background Art

[0002] With the development of society and economy, high-rise buildings are affected by many factors such as planning, site conditions, and building functions, and the facade shapes of buildings have become diversified. Due to the different functional and spatial requirements of the upper and lower parts of high-rise buildings, the outer frame columns of the upper floors cannot be directly and continuously connected to the ground. A conversion structure is required to convert and connect the upper and lower outer frame columns. Different building facade shapes and different internal spatial effects require corresponding conversion structure forms to match them. The conversion structure form needs to be innovatively developed to meet the needs of construction projects. At present, for high-rise buildings with a frame core tube structure system, when the lower outer frame columns are diagonal bracing structures, there is no complete solution for the conversion support of the upper outer frame columns. Summary of the Invention

[0003] An embodiment of the present application provides a conversion system of diagonal braces and core tubes, aiming to provide a building conversion system in which the upper outer frame columns are vertical columns and the lower outer frame columns are diagonal brace structures.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0005] Some embodiments of the present application provide a diagonal brace-to-core tube conversion system, comprising a core tube, multiple diagonal brace structures, multiple first tension beams, multiple upper columns, and multiple frame beams. The multiple diagonal brace structures are arranged sequentially around the core tube, with each diagonal brace structure comprising two diagonal columns. The lower ends of the two diagonal columns in the same diagonal brace structure intersect and connect, and a gap is formed between the upper ends of the two diagonal columns. Multiple first tension beams are arranged between the core tube and the diagonal brace structures. The upper end of a diagonal column intersects and connects with the upper end of a nearby diagonal column in an adjacent diagonal brace structure, forming a first node. Each first node is connected to the core tube via at least one first tension beam. Multiple upper columns are arranged in a one-to-one correspondence with the first nodes, with the lower end of an upper column intersecting and connecting with a first node so that the two diagonal columns at the first node support the upper column. The frame beam is a polygonal enclosure structure comprising multiple cross-beam segments connected end-to-end. The number of cross-beam segments corresponds to the number of first nodes, and the ends of a cross-beam segment intersect and connect at two adjacent first nodes.

[0006] Therefore, in the conversion system of the diagonal brace and the core tube provided in the embodiment of the present application, since the lower ends of the two diagonal columns in each diagonal brace structure intersect and connect, and the upper ends of the two diagonal columns can respectively intersect and connect with the upper ends of the two diagonal columns close to each other in the two adjacent diagonal brace structures, and form two first nodes. Multiple diagonal brace structures can be arranged continuously around the core tube and can be connected end to end to form an enclosed structure, so that the number of first nodes corresponds to the number of diagonal brace structures. And through the first tension beams that intersect and connect at each first node, multiple diagonal brace structures can be connected to the core tube to form an overall stable lower space structure for supporting the upper structure.

[0007] Based on this, when converting the supporting upper columns, the number of upper columns can be equal to the number of diagonal bracing structures, and they can be arranged in a one-to-one correspondence. That is, the lower end of an upper column can be connected to a first node, so that the two diagonal columns at the first node can jointly support the upper column connected to the intersection, so that the gravity load (i.e., vertical load) of the upper column is directly transmitted. In this way, the upper end of the upper column can extend upward and can cooperate with the tension beam above the first node to connect the core tube to support the upper floors of the building. For example, part of the gravity load of the building can be borne by the core tube, and each upper column can transfer the other part of the gravity load to the two diagonal columns at the first node through the first node of connection, so that the diagonal columns in the multiple diagonal bracing structures directly bear the gravity load of the building. In addition, the two diagonal columns of the diagonal bracing structure can also bear the horizontal load of the building (such as wind load and earthquake action), which is beneficial to improve the overall structural lateral stiffness of the building and its earthquake and wind resistance.

[0008] Optionally, the core tube has a polygonal cross-section perpendicular to the vertical direction. The core tube includes multiple exterior walls, multiple interior walls, and multiple internal beams. The multiple exterior walls are sequentially connected to form the polygonal structure. The interior walls and internal beams are arranged between the multiple exterior walls, and at least two exterior walls are further intersected and connected by the interior walls and / or internal beams, forming at least two second nodes. At least some of the first tension beams intersect and connect at the second node at one end proximal to the core tube.

[0009] Optionally, two adjacent exterior walls are connected to form a third node, and at least part of the first tension beam is connected to the third node at one end close to the core tube.

[0010] Optionally, a corner structure is also included. When two adjacent crossbeam segments have a large inward bend toward the core tube, the two crossbeam segments and the two connected diagonal bracing structures form part of a single corner structure. At least one corner structure is positioned corresponding to each third node. A first tension beam is connected between the first and third nodes of the corner structure. This first tension beam is made of steel or reinforced concrete to enhance the tensile strength between the corner structure and the core tube.

[0011] Optionally, there are multiple core tubes, which are arranged in the middle area of ​​the frame beam, with a gap between adjacent core tubes. The conversion system between the diagonal brace and the core tube also includes multiple second tension beams, and adjacent core tubes are connected by the multiple second tension beams.

[0012] Optionally, when the core tube further includes a second node and a third node, between two adjacent core tubes, a second tension beam is connected to at least one structure of the second node and the third node.

[0013] Optionally, the core tube further includes a structural beam, which is arranged at least at a height position close to the first node. Two adjacent third nodes are further connected by a structural beam, one end of the structural beam intersecting with one of the third nodes, and the other end of the structural beam intersecting with the other third node.

[0014] Optionally, two adjacent second nodes are further connected via a structural beam, one end of the structural beam is connected to one of the second nodes, and the other end of the structural beam is connected to the other second node.

[0015] Optionally, the lower end of at least part of the diagonal bracing structure is located on a side of the reference projection area away from the core tube.

[0016] Optionally, the lower end of at least part of the diagonal bracing structure is located on a side of the reference projection area close to the core tube.

[0017] Optionally, the upper column extends in a vertical direction.

[0018] Optionally, the extension direction of the upper column forms an angle with the vertical direction.

[0019] Optionally, the conversion system between the diagonal bracing and the core tube further includes a conversion floor slab; the conversion floor slab covers the connecting frame beams and a plurality of first tension beams, and the conversion floor slab is also connected to the core tube.

[0020] Optionally, it also includes multiple third tension beams, some cross beam sections are connected to one end of at least two third tension beams, and the other end of the third tension beam is connected to the core tube, so that multiple horizontal triangular structures are formed between the frame beam and the core tube through multiple first tension beams and multiple third tension beams.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] In the description of this application, it should be understood that the terms "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings; they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; the term "fixed" should also be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] The core tube is located in the center of the building. It is enclosed by spaces such as elevator shafts, stairways, ventilation shafts, cable shafts, public restrooms, and some equipment rooms. Together with the outer frame, it forms an outer-frame, inner-tube architectural structure. This structure is highly effective in structural stress management and offers excellent seismic resistance, making it a widely adopted mainstream structural form for high-rise buildings internationally. The core tube structure also offers the advantage of maximizing usable space, centralizing various auxiliary service spaces, and ensuring optimal daylighting for the primary functional spaces, as well as good sightlines and convenient internal transportation.

[0032] With the development of society and the economy, high-rise buildings are experiencing a diversification of their facades, influenced by factors such as planning, site conditions, and building functions. Due to the different functional and spatial requirements of the upper and lower parts of high-rise buildings, the outer frame columns of the upper floors cannot be directly connected to the ground. A transfer layer is required to connect the upper and lower outer frame columns.

[0033] For example, the upper and lower parts of a high-rise building have different functions due to the different structures of the upper and lower parts of one floor, and the structure is converted through this floor. This floor is called a structural conversion layer. For example, high-rise buildings are mostly low-rise commercial buildings. The multifunctional requirements of the upper accommodation often require a certain structural form to convert the large space required by the low-rise commercial buildings and the small space with multiple walls and columns required by the upper accommodation. That is, a conversion layer is added. Common structural forms of conversion layers include beam type, hollow truss type, diagonal truss type, box type and plate type. In addition, in house design, if the functions of the upper and lower floors are different, the floor slabs and walls are also structurally strengthened and converted. For high-rise buildings using a frame core tube system, when the lower outer frame columns are diagonal bracing structures, there is no perfect solution for the conversion support of the upper outer frame columns. Based on this, if Figure 1 As shown, an embodiment of the present application provides a diagonal brace and core tube conversion system 100, which may include a core tube 10, multiple diagonal brace structures 20, multiple first tension beams 30, multiple upper columns 40 and side frame beams 50.

[0034] The number of core tubes 10 can be one, two, three or even more. Taking the example of two core tubes 10, the two core tubes 10 can be located in the middle area of ​​the frame beam 50 and arranged in sequence, with a gap between the two core tubes 10. The arrangement direction of the two core tubes 10 arranged in sequence can be a straight line direction or have a certain angle, which is not limited in this application. In the embodiment of the present application, the middle area refers to the internal area enclosed by the closed enclosure structure, rather than the middle position of the internal area.

[0035] Continue to refer to Figure 1 Multiple diagonal bracing structures 20 can be centered around the two core tubes 10 and arranged sequentially around the two core tubes 10, so that the two core tubes 10 are both located in the middle region of the multiple diagonal bracing structures 20. For example, a diagonal bracing structure 20 can include two diagonal columns 21. The lower ends of the two diagonal columns 21 in the same diagonal bracing structure 20 can be converged and connected, and there is a gap between the upper ends of the two diagonal columns 21. In this way, the two diagonal columns 21 in the same diagonal bracing structure 20 can approximately form a V-shaped structure, that is, a lower outer frame column structure arranged at an angle.

[0036] like Figure 1 As shown, multiple first tension beams 30 can be arranged between the core tube 10 and the diagonal bracing structure 20. Since the upper end of a diagonal column 21 can intersect and connect with the upper end of a nearby diagonal column in an adjacent diagonal bracing structure, forming a first node 22 (where intersecting connection refers to the intersection and rigid connection of two components), at least one first tension beam 30 can be intersected at each first node 22, with the end of the first tension beam 30 distal from the first node 22 connected to the core tube 10. For example, a first node 22 can be connected to a core tube 10 via a single first tension beam 30. Alternatively, a first node 22 can be connected to different locations of the same core tube 10 via two, three, or more first tension beams 30, allowing the core tube 10 to distribute the tensile force at the first node 22. Furthermore, a first node 22 can be connected to multiple adjacent core tubes 10 via multiple first tension beams 30, distributing the tensile force at the first node 22 across the multiple connected core tubes 10.

[0037] Based on this, since the lower ends of the two inclined columns 21 in each diagonal bracing structure 20 converge and connect, and the upper ends of the two inclined columns 21 can respectively converge and connect with the upper ends of the two inclined columns 21 close to each other in the two adjacent diagonal bracing structures 20, and form two first nodes 22. Take the upper ends of the two inclined columns 21 in one of the diagonal bracing structures 20 as an example, which extend upward in the left and right directions so that there is a gap between the upper ends of the two inclined columns 21. The upper end of the inclined column 21 on the right side can converge and connect with the upper end of a diagonal column 21 close to the adjacent diagonal bracing structure 20 on the right side, and form a first node 22. The upper end of the inclined column 21 on the left side can converge and connect with the upper end of a diagonal column 21 close to the adjacent diagonal bracing structure 20 on the left side, and form a first node 22. In this way, multiple diagonal bracing structures 20 can be arranged continuously around the core tube 10, and can be connected end to end to form an enclosed structure, so that the number of first nodes 22 corresponds one to one with the number of diagonal bracing structures 20. Furthermore, the first tension beams 30 that converge and connect at each first node 22 can be used to connect the plurality of diagonal bracing structures 20 to the core tube 10 to form an integral lower space structure for supporting the upper building.

[0038] Continue to refer to Figure 1 Taking the upper outer frame columns of a building as an example, which are multiple upper columns 40, when converting and connecting the upper columns 40 and the diagonal bracing structure 20, the number of upper columns 40 can be equal to the number of diagonal bracing structures 20, and arranged in a one-to-one correspondence. That is, the lower end of an upper column 40 can be connected to a first node 22, so that the two diagonal columns 21 at the first node 22 can jointly support the upper column 40 connected to the upper column 40, so that the gravity load (i.e., vertical load) of the upper column 40 is transmitted more directly. In this way, the upper end of the upper column 40 can extend upward and can cooperate with the tension beam to connect the core tube 10 above the first node 22 to support the upper floors of the building. In this way, part of the gravity load of the building can be borne by the core tube 10, and each upper column 40 can transfer the other part of the gravity load to the two diagonal columns 21 at the first node 22 through the first node 22 to enable the diagonal columns 21 in the multiple diagonal bracing structures 20 to directly bear the gravity load of the building. In addition, the two inclined columns 21 of the diagonal bracing structure 20 can also bear the horizontal load (such as wind load and earthquake action) of the building (i.e., at the first node 22), which is beneficial to improving the overall structural lateral stiffness and earthquake and wind resistance of the building.

[0039] The lower end of the same diagonal bracing structure 20 can be connected to the basement structure or foundation structure so that the basement structure or foundation bears the load of the diagonal bracing structure 20. At this time, the diagonal bracing structure 20 as a whole can be approximately V-shaped, with a simple structure.

[0040] For example, Figure 1 As shown, taking the number of core tubes 10 as an example, when arranging multiple diagonal bracing structures 20, the diagonal bracing structures 20 connected end to end can be arranged in sequence in a clockwise direction around the two core tubes 10. Figure 1 Taking the first diagonal bracing structure 20 as an example, the lower end of the first diagonal column 21 in the front can be connected to the lower end of the second diagonal column 21 in the back at the basement structure or foundation. The upper end of the second diagonal column 21 is connected to the upper end of the third diagonal column 21, forming the first first node 22. The lower end of the third diagonal column 21 is connected to the lower end of the fourth diagonal column 21, and the upper end of the last diagonal column 21 is connected to the upper end of the first diagonal column 21, forming the last first node 22. In this way, by the intersection of the upper and lower ends of multiple (even number) diagonal columns 21, while forming the first node 22 to bear the gravity load of the upper column 40, the lower ends of the multiple diagonal columns 21 arranged in an inclined and end-to-end manner are also connected to the basement structure or foundation to form a stable V-shaped or inverted V-shaped spatial structure, which is used to support the upper column 40 while also bearing the horizontal load at the first node 22.

[0041] It should be noted that for the two inclined columns 21 in the same first node 22, a stable triangular structure is formed by the basement structure or foundation where the lower ends of the two inclined columns 21 meet. However, for the two inclined columns 21 in the same diagonal bracing structure 20, in order to form a stable inverted triangular structure for the two inclined columns 21. As Figure 1 shown, the boundary beam 50 may include multiple cross beam segments 51, and the multiple cross beam segments 51 may be connected end to end in sequence to form a polygonal enclosing structure. Among them, the number of cross beam segments 51 corresponds one-to-one with the number of first nodes 22, and both ends of one cross beam segment 51 may meet and be connected to two adjacent first nodes 22. For example, both ends of one cross beam segment 51 may be arranged between the two inclined columns 21 in the same diagonal bracing structure 20, and one end of the cross beam segment 51 may meet and be connected to the upper end of one of the inclined columns 21 at the first node 22, and the other end of the cross beam segment 51 may meet and be connected to the upper end of the other inclined column 21 at the first node 22. In this way, the two inclined columns 21 of the V-shaped structure can form a stable inverted triangular structure through one cross beam segment 51 with a meeting connection, thereby improving the stability of the diagonal bracing structure 20 corresponding to the two inclined columns 21.

[0042] Among them, since two cross beam segments 51, one upper column 40, two inclined columns 21, and at least the first tie beam 30 can meet and be connected at the first node 22. The first node 22 can be used as the stress node of the outer frame structure in the building. Through the direct meeting of the upper column 40 and the two connected inclined columns 21, the gravity load is directly transmitted. And the two inclined columns 21, at least one first tie beam 30, and the two meeting cross beam segments 51 at the first node 22 can balance the horizontal load generated by the gravity load of the upper column 40, ensuring the integrity and stability of the transfer structure.

[0043] In the case where the number of core tubes 10 is multiple, the multiple core tubes 10 located in the middle area of the boundary beam 50 may be distributed in sequence along a straight line or a curved line direction. In addition, taking the number of core tubes 10 being more than three as an example, the three core tubes 10 can also be arranged in a triangular pyramid structure. If the number of core tubes 10 is four, the four core tubes 10 can also be arranged in a square structure.

[0044] Exemplarily, such as Figure 1As shown, a gap exists between adjacent core tubes 10 in the middle region of the frame beam 50. To connect and transfer loads between multiple core tubes 10, the diagonal brace-to-core tube conversion system 100 can further include multiple second tension beams 60. Adjacent core tubes 10 can be connected via these multiple second tension beams 60, allowing the loads (especially horizontal loads) between the two adjacent core tubes 10 to be transferred via these multiple tension beams 60. In this way, through the arrangement of multiple second tension beams 60, multiple dispersed core tubes 10 can be connected together to achieve self-balancing of horizontal loads.

[0045] In some embodiments, as Figure 2 As shown, Figure 2 for Figure 1 A top view of the conversion system 100 of the diagonal brace and the core tube is shown in FIG. Taking the plane where the lower ends of the plurality of diagonal columns 21 are located as a reference plane as an example, the reference plane is generally perpendicular to the vertical direction, that is, parallel to the horizontal plane. Along the vertical direction, the vertical projection of the frame beam 50 on the reference plane is defined as the reference projection area. When arranging the diagonal brace structure 20, the lower ends of some or all of the diagonal brace structures 20 can be made to coincide with the reference projection area, such as Figure 2 The arrangement of the diagonal bracing structures 20 and the frame beams 50 on the left, right and front sides is such that each diagonal column 21 can be arranged in one of the vertical planes. Alternatively, the lower ends of some or all of the diagonal bracing structures 20 can be located on the side of the reference projection area away from the core tube 10, such as Figure 2 The arrangement of the diagonal bracing structure 20 and the frame beam 50 at the middle and rear sides, that is, each diagonal column 21 can be arranged tilted from bottom to top toward the core tube 10. Alternatively, the lower ends of some or all of the diagonal bracing structures 20 can be located on the side of the reference projection area close to the core tube 10, that is, each diagonal column 21 can be arranged tilted from bottom to top toward the direction away from the core tube 10.

[0046] The three arrangements of the aforementioned diagonal bracing structures 20 can be used independently or in conjunction with each other within the same diagonal bracing and core tube conversion system 100. For example, two adjacent diagonal bracing structures 20 can be used. For two diagonal columns 21 within the same diagonal bracing structure 20, one of the columns 21 can be arranged along one of the vertical planes, while the other column 21 can be arranged from bottom to top, approaching or moving away from the core tube 10. Different arrangements can be selected based on load requirements and design requirements, and this application does not impose any limitations on this.

[0047] It should be noted that when the inclined column 21 is arranged from bottom to top, approaching or away from the core tube 10, under the action of gravity load, the inclined column 21 will generate horizontal force (horizontal force in the plane and out-of-plane direction of the V-shaped diagonal bracing structure 20), and the horizontal thrust at the corner is the largest. Based on this, when the upper and lower ends of multiple inclined columns are connected end to end and converged into an integral frame structure through multiple crossbeam segments 51, a part of the horizontal force in the plane of the V-shaped diagonal bracing structure can be paralleled. In addition, the arrangement of multiple first tension beams 30 that converge and connect between the core tube 10 and the diagonal bracing structure 20 can cooperate with the core tube 10, so that the frame structure composed of multiple diagonal bracing structures 20 is connected to the core tube 10 and is used to parallel the remaining horizontal forces, thereby achieving self-balancing of horizontal forces under the action of gravity load. Among them, between the core tube 10 and the first node 22, the axial force borne by the first tension beam 30 can be tension or pressure, as long as it meets the design requirements, and this application does not limit this.

[0048] Based on this, for the upper columns 40, when arranging the upper columns 40 extending upward, the upper columns 40 can be extended in the vertical direction. The extension direction of the upper columns 40 can also have an angle with the vertical direction (i.e., an inclined arrangement). It should be noted that, when the upper columns 40 are arranged at an angle, if the building floor of the conversion system 100 of the diagonal brace and the core tube is higher, that is, the height of the upper columns 40 is greater, the inclination angle of the upper columns 40 can be adjusted accordingly. Correspondingly, if the height of the upper columns 40 is smaller, the upper columns 40 can be flexibly selected within a larger range of inclination angles. Among them, for the inclination direction of the upper columns 40, from bottom to top, the upper columns 40 can be arranged to the left, right, forward and backward, or in a 360° direction according to design requirements. This application does not limit this.

[0049] For example, the floor where the frame beam 50, the plurality of first nodes 22, and the plurality of first tension beams 30 are located is a transfer floor. Above the transfer floor, the upper columns 40 can also be connected to the core tube 10 in their height direction via the tension beam structure, and two adjacent upper columns 40 can also be connected via a cross beam.

[0050] In some embodiments, continue to refer to Figure 2 The cross-section of the core tube 10 perpendicular to the vertical plane can be a polygonal structure. The core tube 10 can include multiple exterior walls 11, multiple interior walls 12, and multiple interior beams 13. The multiple exterior walls 11 can be connected end to end to form the core tube 10 body corresponding to the polygonal structure. The multiple interior walls 12 and the internal beams 13 can be arranged between the multiple exterior walls 11. At least two exterior walls 11 can be connected by the interior walls 12 and / or the internal beams 13 to improve the overall stability of the multiple exterior walls 11.

[0051] For example, the interior space of a rectangular core tube 10, surrounded by four exterior walls 11, can be connected and arranged through multiple interior walls 12 for corresponding isolation, thereby separating multiple smaller building spaces. When connecting adjacent small building spaces, internal beams 13 can be arranged between the interior walls 12 or between the interior wall 12 and the exterior wall 11 to form door openings or window openings between two adjacent small building spaces. The exterior wall 11 can intersect with the interior wall 12 and / or the internal beams 13 to improve the overall stability of the core tube 1. In addition, two adjacent exterior walls 11 can also intersect and form a third node 15.

[0052] For example, Figure 2 As shown, an exterior wall 11 can intersect and connect with an interior wall 12 to form a second node 14, and the other end of the interior wall 12 can also intersect and connect with another exterior wall 11 to form another second node 14. Alternatively, if an interior wall 12 cannot be placed at the location where a second node 14 is required to divide the building space, an interior beam 13 can intersect and connect with an exterior wall 11 at that location to form a second node 14, and the other end of the interior beam 13 can be connected to another exterior wall 11 to form another second node 14. Alternatively, the other end of the interior beam 13 can be connected to one end of an interior wall 12, and the other end of the interior wall 12 can be connected to an exterior wall 11 to form a second node 14.

[0053] Based on this, between two adjacent core tubes 10, as shown in FIG. Figure 2 As shown, the two ends of a second tension beam 60 can be converged and connected to the third nodes 15 on the two core tubes 10. Alternatively, the two ends of the second tension beam 60 can be converged and connected to the second nodes 14 on the two core tubes 10. Alternatively, one end of the second tension beam 60 can be converged and connected to the second node 14 on one core tube 10, and the other end of the second tension beam 60 can be converged and connected to the third node 15 on the other core tube 10. The arrangement of some or all of the second tension beams 60 can be flexibly selected from the above-mentioned arrangements.

[0054] In addition, when arranging the first tension beam 30, since one end of the first tension beam 30 away from the connected core tube 10 converges and connects with the first node 22, the other end of the first tension beam 30 can converge and connect with the second node 14 on the core tube 10 or the third node 15 on the core tube 10. This can be flexibly selected according to needs.

[0055] It should be noted that regarding the second node 14 and the third node 15, taking the third node 15 as an example, since the exterior wall 11 is a structure extending from bottom to top, the first node 15 corresponds to a continuous structure extending from bottom to top. Taking the second node 14 as an example, if the second node 14 is formed by the intersection of the interior wall 12 and the exterior wall 11, the second node 14 can also be regarded as a continuous structure extending from bottom to top. If the second node 14 is formed by the intersection of the interior beam 13 and the exterior wall, the second node 14 can be approximately regarded as a point-like structure. This application does not limit this.

[0056] Based on this, when the load is transmitted through the first tension beam 30 around the core tube 10, taking the first tension beam 30 connected to one of the third nodes 15 as an example, the load can be transmitted to the two adjacent exterior walls 11 through the third node 15. Taking the first tension beam 30 connected to one of the second nodes 14 as an example, the load can be transmitted from the second node 14 through the inner wall 12 and / or the inner beam 13, so that the two exterior walls 11 can bear the load transmitted by the first tension beam 30. Based on this, the load transmitted to the core tube 10 through the first tension beam 30 and the second tension beam 60 can be transmitted to multiple exterior walls 11 through the second node 14 and the third node 15, so that the load can be shared and self-balanced by the entire structure of the core tube 10, which is beneficial to improving the overall stability of the conversion system.

[0057] In some embodiments, as Figure 1 As shown, when stably connecting the diagonal bracing structure 20 and the core tube 10, the conversion system 100 between the diagonal bracing and the core tube can also include multiple third tension beams 70. Some crossbeam sections 51 can intersect and connect with one end of at least two third tension beams 70 to form a fourth node 52. The other ends of the two third tension beams 70 can be connected to different positions of the same core tube 10, or they can be connected to two core tubes 10. Based on this, multiple horizontal triangular structures can be formed between the frame beam 50 and at least one core tube 10 by connecting multiple first tension beams 30 and multiple third tension beams 70. Since the triangle is the most stable component shape, forming multiple triangular structures by connecting the core tube 10 and the frame beam 50 helps to increase the integrity and stability of the connection between the core tube and the multiple diagonal bracing structures 20.

[0058] In the crossbeam 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 tension beam 70 close to the core tube 10 may be connected to the second node 14 or the third node 15 of the core tube 10.

[0059] Taking the outer frame of the building structure system as an example, which includes at least a diagonal bracing structure 20, a first tension beam 30, an upper column 40, and a frame beam 50, in the horizontal direction, the outer frame is provided with multiple corner structures at the third nodes 15 corresponding to multiple outer sides of the core tube 10. For example, Figure 2 As shown, the conversion system 100 between the diagonal brace and the core tube also includes a corner structure 80. When two adjacent cross-beam segments 51 have a large inward bending angle toward the core tube 10, the two cross-beam segments 51 and the two connected diagonal brace structures 20 (or diagonal columns 21) can be regarded as part of the corner structure 80. At least one corner structure 80 can be arranged corresponding to an outer third node 15, and the first node 22 at the corner structure 80 and the third node 15 can be connected by a first tension beam 30. Due to the shape of the outer frame, the corner structure 80 has a large horizontal thrust, which causes the first tension beam 30 between the corner structure 80 and the core tube 10 to bear a large axial tension. Based on this, when arranging the first tension beam 30, the cross-sectional area of ​​the first tension beam 30 can be increased, or the first tension beam 30 can be made of a material with higher tensile strength.

[0060] For example, the first tension beam 30 between the corner structure 80 and the third node 15 can be made of materials such as steel-concrete structure or steel structure, or the first tension beam 30 can be made of concrete components with a high steel reinforcement ratio, both of which can improve the tensile strength of the core tube 10 and the corner structure 80.

[0061] In some embodiments, the main structure of the core tube 10 can be made of one or more building materials such as reinforced concrete, steel-concrete, and steel. Correspondingly, the second tension beam 60 and the main structure of the outer frame (in this case, the outer frame may include the third tension beam 70) can also be made of one or more building materials such as steel-concrete and steel. Among them, the steel-concrete building material can include reinforced concrete, steel-concrete-reinforced concrete, and steel tube (or steel tube) concrete. Taking the diagonal bracing structure 20 as an example, the diagonal columns 21 in the diagonal bracing structure 20 can be made of reinforced concrete, steel-concrete-reinforced concrete, steel tube concrete, or steel.

[0062] For example, the core tube 1 can be made entirely of reinforced concrete or steel structure, or it can be based on reinforced concrete and add steel frames at corresponding positions to increase the structural strength of the core tube 1 at this location. For example, since a large horizontal load needs to be transmitted between the multiple first nodes 22 at the transition layer and the core tube 10. In this way, if the core tube 10 is based on reinforced concrete, the steel content of the horizontal steel bars or steel frames in the exterior wall 11 at a height near the transition layer can be increased to improve the horizontal tensile performance of this part of the exterior wall 11, thereby greatly improving the structural strength and tensile performance of the third node 15. In addition, between two adjacent second nodes 14, the steel content of the horizontal steel bars or steel frames in the interior wall 12 or the interior beam 13 can also be increased to improve the horizontal tensile performance of this part of the interior wall 12 or the interior beam 13, so as to increase the structural strength and tensile performance at the second node 14.

[0063] The reinforcement components of the exterior wall 11, interior wall 12, and interior beam 13 can be arranged only near the transfer layer, or second nodes 14 and third nodes 15 with higher structural strength can be arranged at appropriate locations along the vertical direction of the core tube 10. It is only necessary that these second nodes 14 or third nodes 15 can intersect and connect with the first tension beam 30, the second tension beam 60, or the third tension beam 70, so that the horizontal load transmitted by the first tension beam 30 and the third tension beam 70 can be transmitted to the overall structure of one or more core tubes 10 through the reinforcement components, thereby achieving self-balancing of horizontal forces at the transfer layer and improving the integrity of the structure.

[0064] It should be noted that in the embodiment of the present application, with respect to the outer third nodes 15 on the core tube 10 corresponding to the corner structure 80, if there is only one core tube 10, then the core tube 10 having a polygonal cross-section, and the outer third nodes 15 may be part or all of the third nodes 15. If there are multiple core tubes 10, in a core tube 10, the third nodes 15 closer to other core tubes 10 are referred to as the inner third nodes, and the third nodes 15 farther from other core tubes 10 are referred to as the outer third nodes.

[0065] In some embodiments, as Figure 3 As shown, Figure 3 for Figure 1The figure shows a schematic diagram of the three-dimensional structure of the core tube 10 near the transition layer. The core tube 10 may also include a structural beam 16, which may be arranged near the transition layer in the vertical direction, that is, the structural beam 16 may be arranged at the same horizontal height as the first node 22. A structural beam 16 may be used to connect two adjacent third nodes 15. For example, one end of the structural beam 16 may intersect with one of the third nodes 15, and the other end of the structural beam 16 may intersect with another third node 15. The arrangement of the structural beam 16 strengthens the load-bearing capacity between the two third nodes 15, thereby significantly improving the horizontal tensile bearing capacity of the core tube 10 at the height of the transition layer. In this way, in conjunction with the first tension beam 30, the second tension beam 60, and the third tension beam 70 that intersect and connect at the third nodes 15, horizontal loads can be transferred to the entire structure of one or more core tubes 10, achieving self-balancing of horizontal forces at the transition layer and improving the integrity of the structure.

[0066] In addition, continue to refer to Figure 3 The structural beam 16 can also be arranged on the interior wall 12 at the transfer level, that is, two adjacent second nodes 14 can be connected by the structural beam 16. For example, one end of the structural beam 16 can be connected to one of the second nodes 14, and the other end of the structural beam 16 can be connected to another 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 tension beam 30, the second tension beam 60, or the third tension beam 70, which can also improve the horizontal tensile bearing capacity of the core tube 10 at the height of the transfer level.

[0067] It should be noted that when arranging the structural beam 16, the structural beam 16 can be a steel-concrete component, a steel structure, or a reinforced concrete component with a high reinforcement ratio, which has high tensile strength. The structural beam 16 arranged between two adjacent third nodes 15 can be covered by the outer wall 11. Correspondingly, the structural beam 16 arranged between two adjacent second nodes 14 can also be covered by the inner wall 12 to avoid affecting the interior space effect of the building. In addition, when there is a large horizontal load between two adjacent second nodes 14 or third nodes 15, the cross-sectional size of the structural beam 16 can also be increased accordingly, and even part of the structural beam 16 can be exposed to ensure reliable transmission of the horizontal load, so that the transfer layer can achieve self-balancing of the horizontal force. This application does not limit this.

[0068] Furthermore, the structural beam 16 can also be arranged at other heights within the core tube 10. When connecting two adjacent core tubes 10 via the second tension beam 60, since the second tension beam 60 is not only arranged at the transfer level, multiple second tension beams 60 are also connected to the core tube 10 at other heights, similarly transmitting significant horizontal loads. Therefore, the structural beam 16 can be arranged at the second node 14 and / or third node 15 at other heights within the core tube 10 to intersect and connect the second tension beams 60.

[0069] In some embodiments, the diagonal bracing and core tube conversion system 100 may further include a transfer floor. If there is only one core tube 10, the transfer floor may cover and connect the frame beams 50 and multiple first tension beams 30, and the transfer floor may also be connected to the core tube 10. Thus, through the arrangement of the transfer floor, the transfer floor can also transmit horizontal forces between the core tube 10 and the diagonal bracing structure 20 (and the upper columns 40). Furthermore, if there are multiple core tubes 10, the transfer floor may also cover and connect multiple second tension beams to balance the horizontal loads between two adjacent core tubes 10.

[0070] In other embodiments, below the transfer level, to expand the multi-story building space, the outer frame can be arranged through lower frame beams, lower floor slabs, and some tension beams, via the support connection between multiple diagonal bracing structures 20 and the core tube 10, to form one or more layers of lower building space. Correspondingly, above the transfer level, through the support connection between multiple upper columns 40 and the core tube 10, the outer frame can also be arranged through upper frame beams, upper floor slabs, and some tension beams to form one or more layers of upper building space, similarly expanding the building area of ​​the diagonal bracing conversion system.

[0071] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0072] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection set forth in the claims.
