The application relates to the technical field of buildings, in particular to an inclined strut frame-core tube building structure and a construction method thereof.
Background
In the super high-rise building structure, the frame-core tube building structure is widely used. The frame-core tube building structure includes a core tube structure and a frame structure disposed on a peripheral side of the core tube structure.
The core tube structure is generally a reinforced concrete structure (generally a shear wall), and has better rigidity and ductility, so that the lateral force resistance of the whole frame-core tube building structure can be improved. Meanwhile, the core tube structure is also an important supporting system for vertical load, so that the core tube structure plays an important role in the vertical bearing capacity of the frame-core tube building structure.
The frame construction includes the frame post of a plurality of vertical settings, and the level is provided with the frame roof beam between the adjacent frame post, between frame post and the core section of thick bamboo structure, and frame construction mainly used undertakes most vertical load, also is the effectual second of building structure simultaneously and says antidetonation defence line.
For the frame-core tube building structure with a higher height-to-width ratio and a high-intensity area, if the section of the shear wall is enlarged, although the rigidity of the building structure can be better improved, the dead weight of the building structure is also greatly increased, so that the seismic force is greatly increased, and the seismic requirement cannot be well met; if the cross section of the frame structure is increased, although the rigidity of the building structure can be increased to some extent and the increase of the self weight of the building structure is low, the increase of the rigidity of the whole building structure by the frame structure is limited, and the large cross section of the frame structure affects the indoor use space. Based on this, a new building structure needs to be designed to meet the earthquake-resistant requirements of buildings in high-intensity areas and with high aspect ratios.
Disclosure of Invention
The system integrates the advantages of large rigidity of a shear wall and low self weight of a frame, and is used for solving the problem that the frame-core tube building structure in the prior art cannot be suitable for a high-intensity area and a building with a high height-to-width ratio and high earthquake-resistant requirement.
In order to achieve the purpose, the technical scheme is as follows:
in a first aspect, some embodiments of the present application provide a braced frame-core tube building structure that includes a core tube structure, an outer frame structure, and a braced frame structure. The outer frame structure is arranged on the periphery of the core tube structure. The outer frame structure comprises at least one first frame column which is vertically arranged, and the outer frame structure further comprises a first frame beam which is horizontally arranged between the adjacent first frame columns and/or between the first frame columns and the core tube structure. The inclined strut frame structure is arranged on the periphery of the core tube structure. The diagonal bracing frame structure comprises at least one vertically arranged second frame column, and the diagonal bracing frame structure further comprises a second frame beam horizontally arranged between the adjacent second frame columns and/or horizontally arranged between the second frame columns and the core tube structure. The adjacent second frame columns and the adjacent second frame beams form a first lattice, and/or the second frame columns, the core tube structure and the adjacent second frame beams form a second lattice; inclined struts are arranged in the first sash and the second sash.
The inclined strut frame-core tube building structure is provided with an inclined strut frame structure, and inclined struts are arranged in the first sash and the second sash corresponding to the inclined strut frame structure, so that the whole inclined strut frame structure has large rigidity close to the shear wall, but the dead weight is far smaller than the shear wall and is only slightly larger than that of a common frame structure, therefore, the rigidity of the whole inclined strut frame-core tube building structure is greatly improved, the dead weight is lower, and further the seismic force is lower, so that the inclined strut frame-core tube building structure can adapt to the seismic resistance requirements of buildings with high intensity areas and high aspect ratio.
In a possible implementation form of the first aspect, the brace frame-core tube building structure further comprises a continuous beam for connecting the first frame column in the outer frame structure with the second frame column in the brace frame structure, and/or the continuous beam for connecting the first frame column in the outer frame structure with the second frame beam in the brace frame structure. The arrangement enables the outer frame structure, the inclined strut frame structure and the core tube structure to be connected, the integrity of the inclined strut frame-core tube building structure is better, and the rigidity of the inclined strut frame-core tube building structure is further improved.
In one possible implementation manner of the first aspect, the diagonal brace frame structure is provided in plurality, and the plurality of diagonal brace frame structures are symmetrically arranged in the diagonal brace frame-core tube building structure. In this way, the rigidity of the entire construction structure of the diagonal brace frame-core tube can be further improved.
In one possible implementation manner of the first aspect, each of the braces in the brace frame structure is provided in pairs, and the two braces provided in pairs are symmetrically arranged about a center line of the brace frame structure. Therefore, the stress of each inclined strut is uniform.
In one possible implementation manner of the first aspect, the end portions of the diagonal braces in the first sash are connected with the corresponding second frame column and second frame beam; one end of the inclined strut in the second sash is connected with the corresponding second frame column and the second frame beam, and the other end of the inclined strut is connected with the corresponding second frame beam and the core tube structure. Therefore, the inclined strut can be connected and intersected with the second frame column and the second frame beam at the corresponding positions, or can be connected and intersected with the second frame beam and the core tube structure at the corresponding positions, so that the structural strength and rigidity of the whole inclined strut frame structure are higher.
In a possible implementation manner of the first aspect, two braces are provided in at least a part of the first sash and/or in at least a part of the second sash, and the two braces are arranged in a crossing manner. The arrangement enables the structural strength and rigidity of the diagonal bracing frame structure to be higher.
In a possible implementation manner of the first aspect, one of the two cross braces includes two joint rods, and the ends of the two joint rods close to each other are welded and fixed to the other brace. The arrangement is such that the two cross braces can be coplanar without occupying too much space in the brace frame-core tube building structure.
In one possible implementation of the first aspect, the diagonal brace is hinged within the first sash and within the second sash. By the arrangement, the inclined strut is simple to mount.
In a second aspect, some embodiments of the present application provide a construction method for a bracing frame-core tube building structure according to any one of the above-mentioned aspects. When the diagonal bracing frame structure is manufactured, the diagonal bracing is installed after the second frame column and the second frame beam in the diagonal bracing frame structure are completely built.
Therefore, the inclined strut can be prevented from bearing large internal force under the action of gravity load, and the side force resistance can be prevented from being lost.

In some embodiments, the bracing frame-core tube building structure 100 includes a core tube structure 1, an outer frame structure 2, and a bracing frame structure 3. It should be noted that fig. 1 shows only one plane of the construction structure 100 of the diagonal brace frame-core tube, and in fact, the construction structure 1 of the core tube, the outer frame structure 2 and the construction structure 3 of the diagonal brace frame extend in the height direction of the construction structure 100 of the diagonal brace frame-core tube in the corresponding areas, and are not limited to the one plane shown in fig. 1.

By way of example, with reference to fig. 1, the diagonal frame-core tube building structure 100 shown in fig. 1 has two outer frame structures 2, six first frame columns 21 being arranged in total in the outer frame structures 2, the six first frame columns 21 being distributed on the circumferential side of the core tube structure 1. In other embodiments, the number of the first frame columns 21 in each outer frame structure 2 may also be other, and the number is set according to actual needs, which is not limited in this application.
It should be noted that, as described above, the first frame beams 22 are horizontally arranged between each first frame column 21 and the core tube structure 1, fig. 1 only shows one plane of the bracing frame-core tube building structure 100, and does not represent that only in the plane, the first frame beams 22 are horizontally arranged between each first frame column 21 and the core tube structure 1, and actually, the first frame beams 22 are horizontally arranged between each first frame column 21 and the core tube structure 1 in the plane corresponding to each floor along the height direction of the bracing frame-core tube building structure 100. Similarly, along the height direction of the bracing frame-core tube building structure 100, the first frame beams 22 are horizontally arranged in the plane corresponding to each floor between the adjacent first frame columns 21.
In some embodiments, the first frame beams 22 may not be disposed between adjacent first frame columns 21, and only the first frame beams 22 disposed between each first frame column 21 and the core tubular structure 1 may be used as well. Alternatively, in some embodiments, if the outer frame structure 2 comprises only one first frame post 21, the first frame beam 22 is only present between the first frame post 21 and the core barrel structure 1. Alternatively, in some embodiments, adjacent first frame columns 21 are separated by other structures (e.g., the core barrel structure 1), and then the first frame beams 22 are only disposed between the first frame columns 21 and the core barrel structure 1.
The diagonal bracing frame structure 3 is provided on the periphery side of the core barrel structure 1. The bracing frame structure 3 comprises at least one vertically arranged second frame column 31, the bracing frame structure 3 further comprising a second frame beam 32 horizontally arranged between adjacent second frame columns 31 and horizontally arranged between the second frame columns 31 and the core tube structure 1.
As an example, referring to fig. 1, the bracing frame-core tube building structure 100 shown in fig. 1 has two bracing frame structures 3, four second frame columns 31 are provided in each bracing frame structure 3, and the four second frame columns 31 are distributed on the circumferential side of the core tube structure 1. In other embodiments, the number of the second frame columns 31 in each inclined strut frame structure 3 may also be other, and the second frame columns may be arranged according to actual needs, which is not limited in this application.
It should be noted that, as described above, the second frame beams 32 are horizontally arranged between each second frame column 31 and the core tube structure 1, fig. 1 only shows one plane of the bracing frame-core tube building structure 100, and does not represent that only the plane exists, the second frame beams 32 are horizontally arranged between each second frame column 31 and the core tube structure 1, and actually, the second frame beams 32 are horizontally arranged between each second frame column 31 and the core tube structure 1 in the plane corresponding to each floor along the height direction of the bracing frame-core tube building structure 100. Similarly, referring to fig. 2, second frame beams 32 are horizontally arranged in a plane corresponding to each floor between adjacent second frame columns 31 in the height direction (i.e., Z direction in fig. 2) of the bracing frame-core tube building structure 100.
In some embodiments, the second frame beams 32 may not be disposed between the adjacent second frame columns 31, and only the second frame beams 32 disposed between each second frame column 31 and the core tubular structure 1 may be used as well. Alternatively, in some embodiments, if the sprag frame structure 3 comprises only one second frame post 31, the second frame beam 32 is only present between the second frame post 31 and the core barrel structure 1. Alternatively, in some embodiments, the adjacent second frame columns 31 are separated by other structures (such as the core tube structure 1), and the second frame beams 32 are only disposed between the second frame columns 31 and the core tube structure 1.
Referring to fig. 2, adjacent second frame columns 31 and adjacent second frame beams 32 enclose first cells 33, and in the elevation view shown in fig. 2, each second frame column 31 and each second frame beam 32 enclose a plurality of first cells 33.
In order to increase the rigidity of the bracing frame-core tube building structure 100, a brace 34 is provided in the first sash 33. It should be noted that the brace 34 and the second frame column 31 and the second frame beam 32 each enclose an acute angle.
Referring to fig. 2, the inclined strut 34 is arranged in each first sash 33, so that the whole inclined strut frame structure 3 has a large rigidity close to that of the shear wall, but the dead weight is far smaller than that of the shear wall and is only slightly larger than that of a common frame structure, and therefore, the rigidity of the whole inclined strut frame-core tube building structure 100 is greatly improved, and the dead weight is lower, so that the seismic force is lower, and the inclined strut frame-core tube building structure 100 can meet the seismic requirement of a building with a high-intensity area and a high aspect ratio.
Referring to fig. 1, the sprag frame-core tube building structure 100 further includes a continuous beam 4, the continuous beam 4 being used to connect the first frame post 21 in the outer frame structure 2 with the second frame post 31 in the sprag frame structure 3, and, in some cases, the continuous beam 4 is also used to connect the first frame post 21 in the outer frame structure 2 with the second frame beam 32 in the sprag frame structure 3.
The continuous beam 4 is arranged, so that the outer frame structure 2, the diagonal frame structure 3 and the core tube structure 1 are all connected, the integrity of the diagonal frame-core tube building structure 100 is better, and the rigidity of the diagonal frame-core tube building structure 100 is further improved.
Of course, in some embodiments, the continuous beam 4 may not be provided, and the outer frame structure 2 and the diagonal frame structure 3 are separately connected to the core barrel structure 1, and the same may be used. Alternatively, in some embodiments, only the continuous beam 4 is connected between the first frame post 21 in the outer frame structure 2 and the second frame post 31 in the diagonal frame structure 3, and the continuous beam 4 is not provided between the first frame post 21 in the outer frame structure 2 and the second frame beam 32 in the diagonal frame structure 3, and the same may be used. Alternatively, in some embodiments, only the continuous beam 4 is connected between the first frame post 21 in the outer frame structure 2 and the second frame beam 32 in the diagonal frame structure 3, and the continuous beam 4 is not provided between the first frame post 21 in the outer frame structure 2 and the second frame post 31 in the diagonal frame structure 3, and the same may be used.
Referring to fig. 1, the second frame columns 31 of the diagonal frame structure 3 are arranged coplanar, i.e. the diagonal frame structure 3 lies in one plane. In the X-direction, the braced frame-core tube building structure 100 is symmetrical about the central plane 5, the central plane 5 being a vertical plane. The two bracing frame structures 3 of the bracing frame-core tube building structure 100 are likewise symmetrical with respect to the centre plane 5, i.e. the two bracing frame structures 3 are arranged symmetrically in the bracing frame-core tube building structure 100. In this way, the bracing frame structure 3 is distributed more evenly within the bracing frame-core tube building structure 100, further resulting in an improved stiffness of the bracing frame-core tube building structure 100.
The braced frame-core tube building structure 100 shown in fig. 1 comprises two braced frame structures 3. In other embodiments, the stubby frame-core tube building structure 100 may further include only one stubby frame structure 3, and based on only one stubby frame structure 3, in order to make the structure of the stubby frame-core tube building structure 100 more uniform, the plane of the stubby frame structure 3 may be set to pass through the centerline (centerline extending in the up-down direction) of the stubby frame-core tube building structure 100. Of course, three, four or more diagonal frame structures 3 may be provided in the diagonal frame-core tube building structure 100, and may be used. On this basis, if an even number of the diagonal bracing frame structures 3 are provided, each diagonal bracing frame structure 3 may be made symmetrical with respect to the central plane 5, and if an odd number of the diagonal bracing frame structures 3 are provided, a plane in which one of the diagonal bracing frame structures 3 is located may be made coincident with the central plane 5, and the remaining diagonal bracing frame structures 3 may be made symmetrical with respect to the central plane 5.
To further increase the rigidity of the braced frame-core tube building structure 100. Referring to fig. 2, two braces 34 are disposed in at least a portion of the first sash 33, and the two braces 34 are disposed to cross each other.
Illustratively, referring to fig. 2, the diagonal brace frame structure 3 shown in fig. 2 includes four second frame columns 31 therein, and the diagonal brace frame structure 3 is divided into a first region 6, a second region 7 and a third region 8 by the four second frame columns 31 as boundaries. Wherein, a diagonal brace 34 is arranged in the first sash 33 in the first area 6 and the third area 8, two diagonal braces 34 are arranged in the first sash 33 in the second area 7, and the two diagonal braces 34 in the same first sash 33 are arranged in a crossed manner. The cross arrangement here means: the two braces 34 intersect in an orthographic projection in a plane parallel to the brace frame structure 3.
As the number of the diagonal braces 34 increases, the rigidity of the diagonal brace frame structure 3 is further improved, thereby enabling the rigidity of the diagonal brace frame-core tube building structure 100 to be improved.
Two braces 34 are provided in each first sash 33 corresponding to only the second region 7 in the brace frame structure 3 shown in fig. 2. In other embodiments, two braces 34 may be disposed in a part of the first sash 33 in the second region 7, and one brace 34 may be disposed in the remaining first sash 33. Two braces 34 may be provided in each of the first sash 33 corresponding to the first area 6 and the third area 8, and may be provided as the case may be when designing the brace frame-core tube building structure 100.
Next, how the two diagonal braces 34 are connected and engaged in the case where the two diagonal braces 34 are provided in the first sash 33 will be described. Referring to fig. 3, fig. 3 is a schematic view of the connection of two braces 34 in the same first sash 33 in a brace frame-core tube building structure 100 according to some embodiments of the present application. In some embodiments, one of the two braces 34 in the same first sash 33 includes two rods 341, and the ends of the two rods 341 close to each other are welded and fixed to the other brace 34. The ends of the links 341 facing away from each other are connected to the second frame column 31 and/or the second frame beam 32 corresponding to the first sash 33.
In this way, the two inclined struts 34 can be arranged in a coplanar manner and coplanar with the plane of the inclined strut frame structure 3, and the two inclined struts 34 do not need to be arranged in a direction perpendicular to the plane of the inclined strut frame structure 3, so that the space occupied by the two inclined struts 34 is reduced, and the use space of the inclined strut frame-core tube building structure 100 occupied by the inclined struts 34 is avoided.
Illustratively, referring to fig. 3, the sprag 34 is an i-steel, i.e., the cross section of the sprag 34 taken perpendicular to the plane of the length extension thereof is i-shaped, and the sprag 34 includes two mutually parallel flange plates 3411 and a web 3412 connecting the two flange plates 3411, and correspondingly, the rod segment 341 is also an i-steel, and also includes two mutually parallel flange plates 3411 and a web 3412 connecting the two flange plates 3411. The ends of the two rods 341 close to each other are welded and fixed to the unbroken diagonal brace 34, and specifically, the flange plates 3411 and the webs 3412 of the two rods 341 are welded to the flange plates 3411 on the corresponding sides of the unbroken diagonal brace 34. It should be noted that after the two rods 341 are welded, the two flange plates 3411 of one rod 341 respectively correspond to the two flange plates 3411 of the other rod 341 one by one, and the corresponding flange plates 3411 of the two rods 341 are arranged in a coplanar manner.
In order to increase the structural rigidity and strength of the entire strut frame structure 3, a stiffening plate 9 is provided between the both flange plates 3411 of the unbroken strut 34, the stiffening plate 9 is provided corresponding to the flange plates 3411 of the two-section bar 341, and the stiffening plate 9 is coplanar with the flange plates 3411 of the section bar 341. Four stiffening plates 9 are arranged at the crossing positions of the two diagonal braces 34, two stiffening plates 9 are positioned on one side of the web 3412 of the unbroken diagonal brace 34, and the other two stiffening plates 9 are positioned on the other side of the web 3412 of the unbroken diagonal brace 34. The stiffening plate 9 is welded and fixed with the unbroken diagonal braces 34.
In the above description, the cross section of the inclined strut 34 taken by the plane perpendicular to the length extending direction is i-shaped, and in some other embodiments, the cross section of the inclined strut 34 taken by the plane perpendicular to the length extending direction may also be rectangular, circular, and the like, and may be used, which is not limited in the present application.
To further increase the rigidity of the braced frame-core tube building structure 100. Referring to fig. 2, the ends of the diagonal braces 34 provided in the first sash 33 are connected to the corresponding second frame columns 31 and second frame beams 32. That is, the ends of the diagonal brace 34 intersect the second frame post 31 and the second frame beam 32 at corresponding positions at one point and are connected together. In this way, the length of the diagonal brace 34 is made longer, and the entire first sash 33 can be covered. And, the diagonal brace 34 connects the second frame column 31 and the second frame beam 32 together at the same time, so that the continuity of the connection of the entire diagonal brace frame structure 3 is good, and further, the rigidity of the diagonal brace frame-core tube building structure 100 is higher.
Of course, in other embodiments, the brace 34 may not intersect the second frame post 31 and the second frame beam 32 at a point. If both ends of the diagonal brace 34 are fixed to the two second frame posts 31, or both ends of the diagonal brace 34 are fixed to the two second frame beams 32, respectively, one end of the diagonal brace 34 may be fixed to the second frame post 31, and the other end may be fixed to the second frame beam 32.
The installation of the sprags 34 will be explained below. Referring to fig. 4, fig. 4 is a schematic view of an installation node of the diagonal brace 34 in the diagonal brace frame-core tube building structure 100 provided in some embodiments of the present application. In some embodiments, diagonal brace 34 is hinged within first sash 33. Illustratively, a fixing member 10 may be fixed at a connection position of the second frame post 31 and the second frame beam 32, and the diagonal brace 34 is hinged to the fixing member 10.
Alternatively, referring to fig. 5, fig. 5 is a schematic view of another installation node of the diagonal brace 34 in the diagonal brace frame-core tube building structure 100 provided by some embodiments of the present application. In some embodiments, the end of the brace 34 near the fixing element 10 is connected by the connecting plate 15, and specifically, if the brace 34 is an i-steel and the fixing element 10 is a plate-shaped structure, a threaded hole may be provided on the web 3412 of the brace 34, a threaded hole may be provided on the fixing element 10, a through hole may be provided on the connecting plate 15 corresponding to the threaded holes on the fixing element 10 and the brace 34, and then the brace 34, the connecting plate 15 and the fixing element 10 are connected by a matching bolt, which is equivalent to hinging the brace 34 on the fixing element 10.
If the second frame column 31 and the second frame beam 32 are steel members, the fixing member 10 may be directly welded at a connection position of the second frame column 31 and the second frame beam 32, and if the second frame column 31 and the second frame beam 32 are a reinforced concrete structure or a profile steel concrete structure, the fixing member 10 may be fixed at a connection position of the second frame column 31 and the second frame beam 32 after finishing binding of reinforcing steel bars or finishing fixing of profile steel, and then concrete of the second frame column 31 and the second frame beam 32 is poured. The inclined strut 34 is hinged in the first sash 33, so that the inclined strut 34 is convenient to mount.
Of course, in other embodiments, the brace 34 may be just connected to the first sash 33. For example, if the second frame column 31 and the second frame beam 32 are steel members, the diagonal brace 34 may be directly welded and fixed or fixedly connected at a corresponding position by bolts. If the second frame column 31 and the second frame beam 32 are of a reinforced concrete structure or a section steel concrete structure, a fixed connection structure may be fixed to the reinforcing steel bars or the section steel after the reinforcing steel bars are bound or the section steel is fixed, then concrete of the second frame column 31 and the second frame beam 32 is poured, and finally the inclined strut 34 is fixed to the fixed connection structure.
In order to make the stress of each inclined strut 34 corresponding to the inclined strut frame structure 3 more uniform. Referring to fig. 2, in some embodiments, each brace 34 in the brace frame structure 3 is provided in pairs, and the two braces 34 provided in pairs are arranged symmetrically about the centerline 11 of the brace frame structure 3.
Referring to fig. 2, the first region 6 and the third region 8 are symmetrical about a center line 11, and the center line 11 passes through the second region 7 and divides the second region 7 into two parts symmetrical about the center line 11. Corresponding to the same floor (in the Z direction, the area between two adjacent second frame beams 32 is one floor), the diagonal braces 34 provided in the first sash 33 in the first area 6 and the diagonal braces 34 provided in the first sash 33 in the third area 8 form a pair, and the paired diagonal braces 34 are arranged symmetrically with respect to the center line 11. Two inclined struts 34 are arranged in the first sash 33 in the second region 7, and the two inclined struts 34 in the same first sash 33 in the second region 7 form a pair, and the paired inclined struts 34 are symmetrically arranged about the center line 11.
Referring to fig. 6 and 7, fig. 6 is a schematic plan view of a sprag frame-core tube building structure 100 according to further embodiments of the present application, and fig. 7 is a schematic elevation view of fig. 6 corresponding to C-C and D-D. In other embodiments the second frame posts 31, the core tubular structure 1 and the adjacent second frame beams 32 enclose a second lattice 35, and referring to fig. 7, in an elevation view corresponding to C-C and D-D, the second frame posts 31, each second frame beam 32 and the core tubular structure 1 enclose a plurality of second lattices 35.
Referring to fig. 7, the inclined struts 34 are arranged in the second lattices 35, so that the whole inclined strut frame structure 3 has a large rigidity close to that of the shear wall, but the dead weight is much smaller than that of the shear wall and is only slightly larger than that of a common frame structure, and therefore, the rigidity of the whole inclined strut frame-core tube building structure 100 is greatly improved, and the dead weight is lower, so that the seismic force is lower, and the inclined strut frame-core tube building structure 100 can meet the seismic requirement of a building with a high-intensity area and a high aspect ratio.
Similar to the bracing frame-core tube building structure 100 shown in fig. 2, the bracing 34 in the bracing frame-core tube building structure 100 shown in fig. 7 is connected at one end to the corresponding second frame post 31 and second frame beam 32, and at the other end to the corresponding second frame beam 32 and core tube structure 1. The connection between the diagonal brace 34 and the second frame column 31 and the second frame beam 32 shown in fig. 7 is similar to the connection between the diagonal brace 34 and the second frame column 31 and the second frame beam 32 shown in fig. 2, and will not be described herein again. To the other end of the brace 34, the brace 34 is connected to the second frame beam 32 and the core barrel structure 1, i.e. the brace 34, the second frame beam 32 and the core barrel structure 1 meet at a point and are connected together.
Illustratively, a reinforcing block (not shown) may be installed at the position where the second frame beam 32 is connected to the core tubular structure 1, and then the brace 34 may be hinged or rigidly connected to the reinforcing block, which may be in the form of welding or bolting.
One inclined strut 34 is arranged in each second sash 35 shown in fig. 7, in other embodiments, two inclined struts 34 may be arranged in all the second sashes 35 or in a part of the second sashes 35, and two inclined struts 34 in the same second sash 35 are arranged in a crossed manner. How to connect and arrange two cross braces 34 in the same second sash 35 can refer to the cross braces 34 in the same first sash 33, and the description is omitted here.
The construction 100 of the diagonal brace frame-core tube shown in fig. 6 is provided with two diagonal brace frame structures 3 (the two diagonal brace frame structures 3 are respectively located in the elevations corresponding to C-C and D-D in fig. 6, the two diagonal brace frame structures 3 are respectively divided into two parts by the core tube structure 1), and the two diagonal brace frame structures 3 are symmetrical with respect to the central plane 5. In other embodiments, one bracing frame structure 3 may be provided in the frame-core building structure 100 shown in fig. 6, and the bracing frame structure 3 may be provided through the center line (center line extending in the up-down direction) of the bracing frame-core tube building structure 100 on the basis of one bracing frame structure 3 in order to make the structure of the bracing frame-core tube building structure 100 more uniform. Of course, three, four or more diagonal frame structures 3 may be provided in the diagonal frame-core tube building structure 100, and may be used. On this basis, if an even number of the diagonal bracing frame structures 3 are provided, each diagonal bracing frame structure 3 may be made symmetrical with respect to the central plane 5, and if an odd number of the diagonal bracing frame structures 3 are provided, one of the diagonal bracing frame structures 3 may be made coincident with the central plane 5, and the remaining diagonal bracing frame structures 3 may be made symmetrical with respect to the central plane 5.
Referring to fig. 7, the sprag frame structure 3 shown in fig. 7 has two second frame posts 31 therein, one second frame post 31 forming a fourth region 12 with the core tube structure 1 and the other frame post 31 forming a fifth region 13 with the core tube structure 1. Wherein the fourth area 12 and the fifth area 13 are symmetrical with respect to a centre line 14 of the sprag frame structure 3. Corresponding to the same floor (one floor is the area between two adjacent second frame beams 32 in the Z direction), the diagonal braces 34 provided in the second sash 35 in the fourth area 12 and the diagonal braces 34 provided in the second sash 35 in the fifth area 13 form a pair, and the paired diagonal braces 34 are arranged symmetrically with respect to the center line 14.
In some embodiments, it is also possible to have both a brace frame structure 3 similar to that shown in fig. 1 and a brace frame structure 3 similar to that shown in fig. 6 in the brace frame-core tube building structure 100, and to use the same.
The present application also provides a construction method for the bracing frame-core tube building structure 100 described in any of the above embodiments. In the construction method, the diagonal brace 34 is installed after all the second frame columns 31 and the second frame beams 32 corresponding to the diagonal brace frame structure 3 in the diagonal brace frame-core tube building structure 100 are built. In this way, the following can be avoided: if the inclined strut 34 is installed before the upper second frame column 31 and the upper second frame beam 32 are built, the inclined strut 34 will bear the gravity of the upper second frame column 31, the upper second frame beam 32 and the other inclined strut 34, and then a large internal force is generated in the inclined strut 34, so that the inclined strut 34 loses the capability of resisting the side force.
In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
