Description

Technical Field

[0001] The present invention relates to the technical field of super high-rise building construction, and more particularly to a super high-rise building core tube beam-column connection node and a construction method thereof. Background Art

[0002] The building core tube refers to the structure located in the central part of the building. It is the structural part of the building that bears the main load and resists wind and earthquakes. It is usually formed by elevator shafts, stairs, ventilation shafts, cable shafts, public toilets and some equipment rooms. It has the characteristics of structural stability, vertical passages, high space utilization, high construction efficiency and strong wind and earthquake resistance.

[0003] The building core is usually located in the center of the building, forming an outer frame inner tube structure with the outer frame, and runs through the entire height of the building, taking on the role of structural stability and rigidity of the entire building. The core is generally made of concrete or steel structure, with good compression and bending rigidity.

[0004] The core tube structure is very common in high-rise buildings because it can effectively provide structural stability and earthquake resistance, while allowing for more spacious usable space in the center of the building, so that the main functional space can enjoy good lighting and sight, as well as convenient internal transportation.

[0005] In high-rise buildings, especially super high-rise buildings, the beam-column structure of the core tube often adopts a steel tube column structure. The steel tube column is formed by filling concrete in a steel tube, and the steel tube and its core concrete can jointly bear the building support structure component of the external load. According to the different cross-sectional forms, it can be divided into circular steel tube concrete and square steel tube column. In the steel tube column, the restraining effect of the steel tube on the concrete inside it makes the concrete in a three-way compression state, thereby improving the compressive strength of the concrete; the concrete inside the steel tube can effectively prevent the local buckling of the steel tube.

[0006] However, during the subsequent construction of the steel tube columns of the core tube beam-column structure, the node construction process between the beams and steel tube columns on each floor of the building is relatively complicated, and the construction is difficult and the construction efficiency is low.

[0007] Therefore, how to provide a core tube beam-column node for a super high-rise building that can optimize the construction process and make the construction safer and more efficient is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0008] In view of this, the present invention provides a super high-rise building core tube beam-column connection node and a construction method thereof, aiming to solve the above technical problems.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:

[0010] A super high-rise building core tube beam-column connection node, comprising:

[0011] A steel pipe column, wherein the inner cavity of the steel pipe column is provided with a steel cage, and the top end of the steel cage is exposed from the top surface of the steel pipe column;

[0012] An annular hoop, the annular hoop is sleeved on the steel cage, and the bottom surface of the annular hoop abuts against the top surface of the steel pipe column;

[0013] A connecting beam, one end of which is vertically fixed to the peripheral side of the annular hoop, and the connecting beam can be fixed to the crossbeam reinforcement.

[0014] The beneficial effect of the above technical solution is that the annular hoop is arranged at the top of the steel pipe column, and the annular hoop is cast between the upper and lower steel pipe columns to ensure the connection strength between the annular hoop and the steel pipe column. At the same time, the annular hoop can improve the connection strength between the crossbeam and the steel pipe column. The connecting beam is fixed on the peripheral side of the annular hoop and is fixed by the connecting beam and the steel bars in the crossbeam, thereby realizing a combined structural form of steel tube concrete column and reinforced concrete beam, which has higher seismic resistance and effectively guarantees the internal force transmission of the core tube frame.

[0015] Preferably, an annular groove is formed on the circumferential side of the annular hoop, and one end of the connecting beam is welded and fixed to the groove wall of the annular groove. One end of the connecting beam is inserted into the annular groove and welded and fixed, thereby ensuring the connection strength between the connecting beam and the annular hoop and improving the shear resistance of the connecting beam.

[0016] Preferably, a plurality of support rods are fixed in the annular groove, and the two ends of the plurality of support rods are respectively fixed to the groove top wall and the groove bottom wall of the annular groove. Since the annular hoop is provided with an annular groove on the circumference, the mechanical properties of the annular hoop will inevitably be reduced. The strength of the annular hoop is reinforced by the support rods to improve the bearing capacity of the annular hoop.

[0017] Preferably, it further comprises a screw and a sleeve, the connecting beam is an I-beam, and its web is provided with a plurality of anchor holes, the screw is arranged perpendicular to the web of the connecting beam and passes through the anchor holes, and the two sleeves are respectively screwed on the two ends of the screw on both sides of the web of the connecting beam to be fixed to the cross beam reinforcement. The screw passes through both sides of the web of the connecting beam and is fixed to the web of the connecting beam through the sleeve, and the sleeve is used to fix the cross beam reinforcement, thereby realizing an effective connection between the steel structure connecting beam and the reinforced concrete cross beam.

[0018] Preferably, the inner wall of the sleeve is provided with an internal thread adapted to the screw rod, one end of the sleeve is closed, and the other end is open to be screwed with the screw rod. The sleeve fixes the screw rod to the web of the connecting beam by screwing, and the sealing of one end of the sleeve can prevent the screw rod from being corroded, thereby ensuring the strength and service life of the screw rod.

[0019] Preferably, the outer wall of the sleeve is provided with a plurality of mounting grooves, and the horizontal reinforcement of the beam can be mounted in the mounting grooves corresponding to the circumferential side of the sleeve; the hook reinforcement of the beam can be mounted in the mounting grooves corresponding to the end of the sleeve. The horizontal reinforcement of the beam is placed through the mounting grooves on the circumferential surface of the sleeve, and the hook reinforcement of the beam can be placed in the mounting grooves at the end of the sleeve. The setting of the mounting grooves ensures the effective connection between the reinforcement of the beam and the sleeve, and prevents the occurrence of the problem of reduced connection strength between the beam and the steel pipe column caused by disturbance of the reinforcement during the pouring of concrete for the beam.

[0020] Preferably, a plurality of through holes corresponding to the main bars of the steel cage are opened on the annular surface of the annular hoop. The annular hoop can be sleeved on the steel cage through the through holes on the annular hoop, and the annular hoop and the steel pipe column form an integrated structure.

[0021] Preferably, the height of the steel pipe column is the same as the floor height, and the height of the connecting beam is less than the height of the cross beam. The height of the steel pipe column is adapted to the floor height, and the annular hoop is arranged at the position corresponding to the floor deck of each floor to facilitate the anchoring between the connecting beam and the cross beam. The height of the connecting beam is less than the height of the cross beam. When pouring the cross beam concrete, the connecting beam can be wrapped in the cross beam concrete to prevent the connecting beam from rusting due to long-term exposure to the external environment.

[0022] Preferably, a triangular stiffening plate is fixed between the flange plate of the connecting beam and the annular surface of the annular hoop. The stiffening plate further improves the connection performance between the connecting beam and the annular hoop, ensures the reliability of the connection between the connecting beam and the annular hoop, and ensures that the connecting beam has sufficient bearing capacity.

[0023] The present invention also provides a super high-rise building core tube beam-column connection construction method, which adopts a super high-rise building core tube beam-column connection node in the above technical solution for construction, comprising the following steps:

[0024] S1. Install the steel pipe column and place the steel cage inside the steel pipe column so that the top of the steel cage is exposed from the top surface of the steel pipe column;

[0025] S2, putting the annular hoop on the steel cage so that the bottom surface of the annular hoop abuts against the top surface of the steel pipe column;

[0026] S3, pouring column concrete from the annular cavity of the annular hoop into the inner cavity of the steel pipe column; when constructing the upper steel pipe column, the steel cage of the upper steel pipe column is connected with the steel cage of the lower steel pipe column, and then the upper steel pipe is sleeved on the upper steel cage, and the bottom end of the upper steel pipe is welded and fixed to the annular hoop of the lower layer, and then the annular hoop of the upper layer is installed;

[0027] S4. Weld and fix the connecting beam to the peripheral side of the annular hoop; weld and fix one end of the connecting beam to the groove wall of the annular groove on the peripheral side of the annular hoop, and install the screw and sleeve at the same time.

[0028] S5. Install the beam formwork, fix the beam reinforcement and the connecting beam, and pour the beam concrete. After the beam formwork is installed, connect the beam reinforcement and the sleeve. When pouring the beam concrete, the mixed concrete wraps the connecting beam and the annular hoop corresponding to the top wall and bottom wall of the annular groove, so that the connecting beam, the annular hoop, the steel pipe column and the beam are anchored to form an integrated structure.

[0029] It can be seen from the above technical scheme that compared with the prior art, the present invention discloses a super high-rise building core tube beam-column connection node and a construction method thereof, in which an annular hoop is sleeved on the top surface of the steel pipe column, the annular hoop and the steel pipe column are cast into a whole, and the connecting beam is fixed to the annular hoop.

The construction process is simple, and the construction efficiency is safer and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See attached Figures 1 to 4 The embodiment of the present invention discloses a super high-rise building core tube beam-column connection node, comprising:

[0044] A steel pipe column 1, wherein the inner cavity of the steel pipe column 1 is provided with a steel cage 11, and the top end of the steel cage 11 is exposed from the top surface of the steel pipe column 1;

[0045] The annular hoop 2 is sleeved on the steel cage 11, and the bottom surface of the annular hoop 2 abuts against the top surface of the steel pipe column 1;

[0046] A connecting beam 3, one end of which is vertically fixed to the peripheral side of the annular hoop 2, and the connecting beam 3 can be fixed to the crossbeam reinforcement.

[0047] like Figure 1 and 2 As shown, the steel pipe column is formed by pouring concrete in the steel pipe, the steel cage is composed of main bars and stirrups, the steel cage is installed in the inner cavity of the steel pipe, the main bars at the top of the steel cage are exposed from the top surface of the steel pipe column, the steel pipe column and the cross beam are connected by the connecting beam around the annular hoop, the annular hoop is sleeved on the steel cage and arranged on the top surface of the steel pipe column, when pouring concrete of the steel pipe column, it can be poured from the annular cavity of the annular hoop, so that the annular hoop and the steel pipe column form an integrated structure, which effectively ensures the connection between the annular hoop and the steel pipe, and the annular hoop as a beam-column connection node will not have uneven settlement, the connecting beam is fixed on the outer annular surface of the annular hoop, the connecting beam can be connected to the steel bars in the cross beam, and the cross beam is connected by the connecting beam to ensure the overall performance of the super-high-rise core tube frame.

[0048] In order to further optimize the above technical solution and ensure the stability of the connection between the connecting beam and the annular hoop, an annular groove 23 is opened on the circumference of the annular hoop 2, and one end of the connecting beam 3 is welded and fixed to the groove wall of the annular groove 23.

[0049] The connecting beam is fixed by the annular groove. The setting of the annular groove can set the connecting beam at any position on the annular surface of the annular hoop to meet the use requirements of core tubes with different structural forms.

[0050] In order to further optimize the above technical solution, multiple support rods 21 are fixed in the annular groove 23, and the two ends of the multiple support rods 21 are respectively fixed to the groove top wall and the groove bottom wall of the annular groove 23. Since the annular groove is provided on the outer periphery of the annular hoop, the force bearing performance of the annular hoop will be affected, so the support rods are used for reinforcement.

[0051] A support rod is vertically arranged at intervals of 30 cm along the arc length direction of the annular groove of the annular hoop, and both ends of the support rod are fixed to the top wall and bottom wall of the annular groove. The support rod is utilized to improve the load-bearing capacity of the annular hoop, ensure the effective bearing capacity of the beam-column connection node, and improve the structural strength of the beam-column connection node.

[0052] In this embodiment, a screw rod 4 and a sleeve 5 are also included. The connecting beam 3 is an I-beam, and its web is provided with a plurality of anchor holes 31. The screw rod 4 is arranged perpendicular to the web of the connecting beam 3 and passes through the anchor holes 31. Two sleeves 5 are respectively screwed on the two ends of the screw rod 4 on both sides of the web of the connecting beam 3 to be fixed to the crossbeam reinforcement.

[0053] like Figure 1 and 4 As shown, the screw is arranged perpendicular to the web of the connecting beam and passes through the anchor hole on the connecting beam. The two ends of the screw are locked by sleeves to fasten the screw to the connecting beam. The sleeve can be used to anchor the steel bars of the crossbeam.

[0056] The horizontal reinforcement of the beam is connected to the two sleeves at both ends of the beam. The horizontal reinforcement is parallel to the length direction of the connecting beam and is placed in the installation groove on the circumference of the sleeve. Horizontal reinforcement is provided on both sides of the web of the connecting beam. The hook reinforcement can be installed from the installation groove at the end of the sleeve and sleeved on the outer circumference of the connecting beam to hook the horizontal reinforcement on both sides of the connecting beam to prevent the horizontal reinforcement from deforming and affecting the construction quality. It is equivalent to a square steel cage being provided in the beam. The connecting beam is inserted into the inner cavity at the end of the square steel cage. The two hook reinforcements are interlocked to form stirrups in the direction, and the horizontal reinforcement, the connecting beam and the sleeve are firmly connected. In this way, the effective connection between the beam reinforcement and the connecting beam can be ensured. The beam concrete can wrap the connecting beam, so that the beam-column node is cast as a whole, ensuring the integrity of the core tube frame structure.

[0057] In order to further optimize the above technical solution and ensure that the annular hoop can effectively cover the steel cage, a plurality of through holes 22 corresponding to the main bars of the steel cage 11 are opened on the annular surface of the annular hoop 2.

[0058] The inner diameter of the annular cavity of the annular hoop is smaller than the inner cavity of the steel pipe. The annular hoop is sleeved with the steel cage through the through hole on its annular surface. The main reinforcement of the steel cage is inserted into the annular surface of the annular hoop, so that the annular hoop and the annular steel cage can be connected as a whole. When pouring concrete in the steel pipe, the annular hoop, the steel pipe and the steel cage can be cast as a whole.

[0059] In this embodiment, the height of the steel pipe column 1 is the same as the floor height, and the height of the connecting beam 3 is less than the height of the cross beam. The annular hoop is set at the top of the steel pipe column, and the annular hoop corresponds to the cross beam position of the floor. The height of the connecting beam should be less than the height of the cross beam, so that the other end of the connecting beam can be inserted into the inner cavity of the steel cage in the direction of the cross beam, and the connecting beam can be completely wrapped when pouring the cross beam concrete, and the connecting beam is anchored at the beam end of the cross beam to achieve the connection between the steel structure connecting beam and the cross beam of the reinforced concrete structure.

[0060] In order to further optimize the above technical solution and further improve the bearing capacity and structural strength between the connecting beam and the annular hoop, a triangular stiffening plate 32 is fixed between the flange plate of the connecting beam 3 and the annular surface of the annular hoop 2. One side of the stiffening plate is welded and fixed to the upper flange plate or the lower flange plate of the connecting beam, and the end is welded and fixed to the annular surface of the top peripheral side or the annular surface of the bottom peripheral side of the annular hoop. By setting the stiffening plate, the connection between the connecting beam and the annular hoop can be reinforced to improve the connection strength between the connecting beam and the annular hoop.

[0061] Embodiment 2:

[0062] The embodiment of the present invention discloses a method for connecting the core tube beams and columns of a super high-rise building. The method adopts a super high-rise building core tube beam-column connection node in embodiment 1 for construction, and includes the following steps:

[0063] S1, installing the steel pipe column 1, placing the steel cage 11 in the steel pipe column 1, so that the top of the steel cage 11 is exposed from the top surface of the steel pipe column 1;

[0064] The steel pipe column is positioned according to the measurement to ensure its verticality. The height of the steel pipe corresponds to the height of the floor. The length of the steel cage should be greater than the height of the steel pipe column to ensure that the steel cage can be exposed from the top surface of the steel pipe.

[0065] S2, sleeve the annular hoop 2 on the steel cage 11, so that the bottom surface of the annular hoop 2 abuts against the top surface of the steel pipe column 1;

[0066] The position of the annular hoop corresponds to the position of the bottom crossbeam of the floor deck. The through hole on the annular surface of the annular hoop corresponds to the main reinforcement of the steel cage and is inserted. After the annular hoop is placed in place, it is necessary to ensure that the bottom surface of the annular hoop is in contact with the top surface of the steel pipe, and at the same time ensure that there is no large gap between the steel pipe and the annular hoop to prevent leakage during concrete pouring of the steel pipe column;

[0067] In order to ensure that there is no leakage between the annular hoop and the steel pipe, sealant can be injected between the top of the steel pipe and the bottom annular surface of the annular hoop.

[0069] When pouring concrete for the steel pipe column, the height of the concrete surface is flush with the top surface of the annular hoop, and the annular hoop and the steel pipe are poured into an integral structure;

[0070] In order to further optimize the above technical solution, when the upper and lower steel pipe columns are connected, the upper steel cage and the lower steel cage can be connected through a sleeve first, and then the upper steel pipe is inserted into the upper steel cage, and the bottom end face of the upper steel pipe is welded and fixed to the top end face of the lower annular hoop, the upper steel pipe and the lower annular hoop are connected into a whole, and then the upper annular hoop is installed.

[0071] S4, welding and fixing the connecting beam 3 and the peripheral side of the annular hoop 2;

[0072] One end of the connecting beam is welded and fixed to the annular groove of the bearing of the annular hoop. After the connecting beam is welded, the screw and sleeve are installed. It should be noted that the length of the screw exposed on one side of the connecting beam web needs to be slightly smaller than the length of the sleeve inner cavity to ensure that after the sleeve is screwed into the screw, the end face of the sleeve opening is in contact with the plate surface of the connecting beam web.

[0073] S5. Install the beam formwork, fix the beam reinforcement to the connecting beam 3, and pour the beam concrete.

[0074] Tie the horizontal reinforcement of the crossbeam. The horizontal reinforcement at both ends of the crossbeam is placed in the installation groove of the sleeve circumference. The horizontal reinforcement is installed on both sides of the connecting beam. Then tie the hook reinforcement. The hook reinforcement is embedded in the installation groove at the end of the sleeve. The hook reinforcement on both sides of the connecting beam is interlocked with each other. The joints of the two hook reinforcements are welded and fixed to form stirrups, which are sleeved on the outer periphery of the horizontal reinforcement. When the crossbeam concrete is poured, the connecting beam is wrapped in it. This ensures that the connecting beam and the crossbeam are anchored as a whole, ensuring the structural strength of the core tube beam-column connection node.
