Description

Technical Field

[0001] The present application relates to the technical field of building structures, and specifically to a super-high-rise steel structure giant frame building structure. Background Art

[0002] Super high-rise steel structure mega frame building is a special building structure system, which mainly consists of a main structure composed of large components such as giant beams and giant columns, and a secondary structure composed of conventional beams and columns. This structural system is also called a primary-secondary frame structure, in which the main frame is a mega frame and the secondary frame is a normal frame.

[0003] The existing patent (publication number: CN217679652U) discloses a super-high-rise steel structure giant frame building structure, including floor slabs, steel beams, steel columns and core tubes. An energy dissipation and shock absorption device is arranged between the steel columns and the core tube. The energy dissipation and shock absorption device can transmit the pressure from the floor slabs to the core tube, and can also transmit the horizontal force on the steel columns to the core tube. The upper beam and the lower beam cooperate with the damper and the shock absorber to bear the vertical load and the horizontal load. The damper cooperates with the shock absorber to effectively improve the overall lateral stiffness of the building structure in the case of earthquake or wind. The damper converts the seismic energy into heat energy through the reciprocating motion of the fire in the damping medium and dissipates it, so that the movement speed of the device is gradually reduced to achieve the purpose of damping, thereby preventing a large displacement between the floor slab and the core tube and the steel column. This design reduces a large number of combined reinforcement devices, reduces a large amount of steel, saves costs, and improves construction efficiency.

[0004] A lower beam is provided on one side of the shock absorber described in the above-mentioned device, and the upper beam and the lower beam cooperate with the damper and the shock absorber to withstand vertical loads and horizontal loads. The damper cooperates with the shock absorber in the event of an earthquake or wind. However, by arranging the damper and the shock absorber between the upper beam and the lower beam, the vertical load can be damped, but the longitudinal load damping effect is poor. Since the height and volume of super-high-rise steel structure buildings are large, they are more susceptible to the influence of wind. When subjected to wind loads, the steel columns and steel beams are prone to hard collisions, causing safety hazards. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a super-high-rise steel structure giant frame building structure with the advantages of good wind load resistance, etc., and solves the problem that by setting dampers and shock absorbers between the upper beams and the lower beams, the vertical load can be reduced, but the longitudinal load reduction effect is poor. Since the height and volume of super-high-rise steel structure buildings are large, they are more susceptible to the influence of wind. When subjected to wind loads, their steel columns and steel beams are prone to hard collisions, causing safety hazards.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a super-high-rise steel structure mega-frame building structure, comprising a steel column, an L-shaped connector is provided on the outer surface of the steel column, two right-angled beams are provided inside the L-shaped connector, and two energy-absorbing frames are fixedly connected inside each of the beams;

[0007] A plurality of groups of springs arranged at equal distances are arranged between the two inner side walls of each cross beam, a plurality of steel bars arranged at equal distances are arranged inside each cross beam, and each spring is sleeved with the steel bar adjacent to it.

[0008] Through the above scheme, when the set crossbeam is subjected to external wind load, the energy-absorbing frame is compressed on one side and the spring is compressed at the same time, so that the energy of the load can be effectively absorbed. In combination with the setting of the damper, the buffering and energy-absorbing effect of the wind load can be achieved, and the squeezing of the floor slab and the core tube by the crossbeam can be effectively avoided, thereby improving the overall stability. Through the set pad, the L-shaped connector can be protected when subjected to lateral load, thereby avoiding hard collision between the crossbeam and the L-shaped connector.

[0009] Furthermore, the L-shaped connector is slidably sleeved with the steel column, and a plurality of countersunk holes penetrating the steel column are provided on the surface of the L-shaped connector.

[0010] Through the above solution, the countersunk hole is provided to facilitate the connection between the L-shaped connector and the steel column.

[0011] Furthermore, a double-threaded fixing rod is inserted into the interior of each countersunk hole, and nuts are threadedly connected at both ends of each double-threaded fixing rod.

[0012] Through the above solution, the purpose of fixing the L-shaped connecting piece can be achieved by setting the nut.

[0013] Furthermore, both side surfaces of one end of each cross beam close to the steel column are in contact with pads, and the other side of each pad is in contact with the L-shaped connecting piece.

[0014] Through the above solution, by setting the pad, it is possible to avoid the cross beam from having a hard contact with the L-shaped connecting piece when the cross beam is subjected to external wind load.

[0015] Furthermore, the outer surfaces of the two cross beams are provided with a plurality of connection holes penetrating the L-shaped connection pieces and the cushion blocks.

[0016] Through the above solution, by setting the connecting hole, it is convenient for the user to connect the crossbeam with the L-shaped connecting piece.

[0017] Furthermore, the cross section of each of the energy absorbing frames is set to be X-shaped, and each of the energy absorbing frames is integrally formed of a spring steel plate.

[0018] Through the above solution and the X-shaped arrangement, the purpose of absorbing energy of the load can be achieved.

[0019] Furthermore, each of the steel bars is fixedly embedded in a crossbeam adjacent to it, and each intersection between the steel bars is tied with external iron wire.

[0020] Through the above scheme, by setting the steel bars, the user can build the external floor.

[0021] Furthermore, a plurality of dampers arranged at equal distances are provided between the two inner side walls of each cross beam.

[0022] Through the above solution, the wind load can be effectively buffered by arranging the damper in conjunction with the spring and the energy absorbing frame.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This super-high-rise steel structure giant frame building structure can effectively absorb the energy of the load by compressing one side of the extrusion energy absorption frame and compressing the spring when the cross beam is subjected to external wind load. In combination with the setting of the damper, it can achieve the buffering and energy absorption effect of the wind load, effectively avoid the cross beam from squeezing the floor slab and the core tube, and improve the overall stability. The set pad can protect the L-shaped connector when subjected to lateral load, avoiding hard collision between the cross beam and the L-shaped connector. BRIEF DESCRIPTION OF THE DRAWINGS
