Description

Technical Field

[0001] This application relates to the field of architecture, and more specifically, to beam-column structures. Background Technology

[0002] Beam-column structures are a crucial component of a building's load-bearing system in the construction industry. Composed of beams and columns, they support the self-weight of roofs, floors, and walls, as well as various loads generated during use. Beam-column structures not only relate to the safety, functionality, and aesthetics of buildings but also involve economic efficiency and sustainability. Therefore, the research and application of beam-column structures are an important direction for the sustainable development of the construction industry.

[0003] Current methods for connecting beams and columns involve bolts, welding, or riveting. These methods require on-site welding or drilling at joints, resulting in low levels of industrialization, slow construction speed, severe pollution, and high resource consumption. Therefore, providing a beam-column structure with superior performance and faster construction speed is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a beam-column structure with superior performance and faster construction speed.

[0005] Specifically, the beam-column structure includes: a hollow column extending along a first direction, with a notch provided on the side of the hollow column facing a second direction, the second direction being perpendicular to the first direction; a first beam and a second beam extending along a third direction, with a first end of the first beam along the third direction and a second end of the second beam along the third direction being disposed opposite each other, and both the first end of the first beam and the second end of the second beam being disposed in the notch of the hollow column, the third direction being perpendicular to both the first and second directions; and a connector, at least a portion of which is disposed inside the hollow column, the connector including a base plate and a plurality of pins, the ends of the plurality of pins being connected to the base plate, both the first end of the first beam and the second end of the second beam being provided with insertion holes, the plurality of pins being configured to be inserted into the insertion holes to connect the first beam and the second beam.

[0006] According to the technical solution of this application embodiment, in the beam-column structure, the first end of the first beam and the second end of the second beam are respectively disposed in the recess of the hollow column, and the two ends of the two beams are provided with insertion holes, which can be used with pins in the connector, so that the connector can connect the two beams through the pins, so that the two beams are fixedly disposed in the hollow column, forming a beam-column structure with a stable structure and better performance. At the same time, the assembly process of this beam-column structure is relatively simple, which helps to improve the construction speed of the beam-column structure and reduce the construction burden on the construction site.

[0007] In some possible implementations, the hollow column has internal reinforcement members attached to its inner wall to improve its bending resistance.

[0008] In some possible implementations, the reinforcing member includes a threaded structure extending along a first direction and disposed inside the hollow column.

[0009] In some possible implementations, the hollow column is a square column, with a threaded structure attached to the center of the cross-section of the inner wall of each side of the square column.

[0010] In some possible implementations, the reinforcing member includes a plurality of reinforcing ribs distributed circumferentially along the inner wall of the hollow column.

[0011] The technical solution of this embodiment incorporates both a threaded structure and reinforcing ribs inside the hollow column, which can significantly improve the bending resistance of the hollow column and enhance the overall performance of the hollow column and beam-column structure.

[0012] In some possible implementations, the hollow column is a square column with multiple reinforcing ribs at the corners of the square column.

[0013] In some possible implementations, each of the plurality of reinforcing ribs is attached to a 1 / 4 region of the inner wall of the hollow column in cross-section.

[0014] Through the technical solution of this embodiment, the threaded structure can cooperate with the reinforcing ribs. That is, the threaded structure is attached to the center of the inner wall of the hollow column in the cross-section, while the reinforcing ribs are attached to 1 / 4 of the inner wall of the hollow column in the cross-section. The threaded structure and the reinforcing ribs can provide uniform and comprehensive reinforcement support to the inner wall of the hollow column, thereby effectively and reliably improving the bending resistance and overall performance of the hollow column.

[0015] In some possible implementations, multiple reinforcing ribs are grouped together, and multiple groups of reinforcing ribs are disposed inside the hollow column along a first direction.

[0016] In some possible implementations, the first end of the first beam has a first protrusion facing away from the connector, the size of the first protrusion in the first direction gradually increases in the direction toward the hollow column, or gradually increases and then tends to a fixed value; and / or, the second end of the second beam has a second protrusion facing away from the connector, the size of the second protrusion in the first direction gradually increases in the direction toward the hollow column, or gradually increases and then tends to a fixed value.

[0017] By providing a first protrusion at the first end of the first beam and a second protrusion at the second end of the second beam, the shear bearing capacity in the first direction (e.g., the vertical direction) can be improved.

[0018] In some possible implementations, the first protrusion facing away from the connector has a sloped or curved surface; and / or, the second protrusion facing away from the connector has a sloped or curved surface.

[0019] In some possible implementations, in the connector, the substrate is provided with an elastic member and a snap fastener, the snap fastener being provided with a movable limiting member; when the limiting member is correspondingly provided to the snap fastener, the limiting member is used to limit the snap fastener to the interior of the substrate; when the limiting member moves, the elastic member is used to pop the snap fastener out so that the snap fastener extends out of the substrate, and the snap fastener is attached to the first end of the first beam or the second end of the second beam.

[0020] In some possible implementations, the connector further includes: an additional plate and a plug rod, the end of which is connected to the additional plate; the base plate is provided with a limiting hole corresponding to the buckle, and the plug rod passes through the limiting hole to limit the buckle as a limiting member.

[0021] Through this embodiment, the additional plate and insert rod in the connector serve as movable limiting components, allowing for repeated use in the assembly process of multiple beam-column structures. Furthermore, when the additional plate and insert rod are installed above the base plate, the latch can be confined within the base plate, facilitating the transport of the connector, reducing transportation costs, and minimizing the possibility of damage to the latch during transport.

[0022] In some possible implementations, the beam-column structure further includes: a first diagonal brace and a second diagonal brace, the two ends of the first diagonal brace being connected to the side of the first beam away from the connector and the side of the hollow column facing the first beam, and the two ends of the second diagonal brace being connected to the side of the second beam away from the connector and the side of the hollow column facing the second beam.

[0023] By adding diagonal bracing to beam-column structures, the load-bearing capacity at weak points can be increased, thereby improving the overall load and structural stability of the beam-column structure.

[0024] In some possible implementations, the first diagonal brace includes: a first connecting plate and a first diagonal brace plate, the two end faces of the first diagonal brace plate being respectively connected to the first connecting plate, and the large surface of the first connecting plate being attached to the hollow column or the first beam; and / or, the second diagonal brace includes: a second connecting plate and a second diagonal brace plate, the two end faces of the second diagonal brace plate being respectively connected to the second connecting plate, and the large surface of the second connecting plate being attached to the hollow column or the second beam.

[0025] In some possible implementations, a plurality of first diagonal bracing plates are connected between two first connecting plates; and / or, a plurality of second diagonal bracing plates are connected between two second connecting plates.

[0026] In some possible implementations, a plurality of first diagonal braces connect the first beam to the hollow column; and / or, a plurality of second diagonal braces connect the second beam to the hollow column.

[0027] In some possible implementations, the beam-column structure further includes: a baffle; the first beam and the second beam are located on opposite sides of the recess in the hollow column, and the baffle is fastened between the opposite sides of the recess.

[0028] The technical solution of this implementation method treats the beam-column structure as a prefabricated product, which is assembled from hollow columns, first beams, second beams, connectors and baffles, thereby improving the integration of the beam-column structure.

[0029] In some possible implementations, the notch is provided with a waterproof and breathable material, including polytetrafluoroethylene.

[0030] The technical solution of this embodiment can reduce the risk of water and other liquids entering the interior of hollow columns and causing corrosion, thereby further improving the reliability of hollow columns and beam-column structures.

[0031] In some possible implementations, the hollow column has an insulation layer inside, which includes rigid polyurethane.

[0032] Through the technical solution of this embodiment, the heat insulation layer can play a role in heat insulation of the hollow column, reducing the impact of temperature on the hollow column.

[0033] In some possible implementations, the beam-column structure is made of shape memory alloy SMA.

[0034] The technical solution of this embodiment uses SMA material for the beam-column structure, which allows the beam-column structure to automatically recover its original shape after being subjected to mechanical loads, thereby improving the seismic performance of the beam-column structure.

[0058] The technical solutions in this application will now be described in conjunction with the accompanying drawings. The detailed descriptions and drawings of the following embodiments are used to exemplarily illustrate the principles of this application, but should not be used to limit the scope of this application; that is, this application is not limited to the described embodiments.

[0059] This application's embodiments are applicable to prefabricated buildings, also known as modular buildings, which are a construction method that produces building components in factories or component plants. It employs industrialized production technology to prefabricate building components (such as wall panels, floor slabs, beams, columns, etc.) in production workshops, and then transports them to the construction site for assembly. Prefabricated buildings have advantages such as low energy consumption, easy quality control, fast construction speed, better construction site environment, and fewer shrinkage cracks. As one of the important development directions of building structures both domestically and internationally, prefabricated buildings not only benefit the development of my country's building industrialization and improve production efficiency, but also significantly reduce construction waste.

[0060] In prefabricated buildings, the beam-column structure is a crucial component, determining the building's load-bearing capacity, stability, and overall performance. Common methods for beam-column connections include: ① Welding: The contact surfaces of the beam and column are melted and solidified using high-temperature heating or methods such as electric arcs or lasers, forming a robust connection. Welding offers high strength and rigidity and is frequently used in steel structures. ② Bolts: Bolts are used to secure the beam and column together. This method facilitates disassembly and maintenance, making it suitable for situations requiring frequent component replacement. Bolt connections can be friction, tensile, or shear connections, depending on design requirements. ③ Adhesive bonding: Special high-strength adhesives are used to bond the contact surfaces of the beam and column together. Adhesive bonding provides excellent adhesion and is suitable for applications requiring high connection strength.

[0061] Among the connection methods mentioned above, welding connections require on-site welding or drilling at the joints, making the on-site assembly process complex and slowing down the construction speed. Bolted connections require accurate application of tightening torque to ensure the preload and anti-loosening performance of the connection. Improper torque control may result in the connection being too tight or too loose, affecting the safety and reliability of the structure, and consequently impacting the performance of the beam-column structure. Adhesive connections generally require a certain amount of time to cure the adhesive, which may prolong the construction period. Furthermore, during the curing period, the structure may be affected by environmental factors such as temperature and humidity, which may also affect the performance of the beam-column structure.

[0062] In view of this, the present application provides a novel beam-column structure with a new assembly method. This beam-column structure has better performance and faster construction speed, without bringing additional burden and pollution to the construction site.

[0063] Figure 1 A schematic structural diagram of the beam-column structure 10 provided in an embodiment of this application is shown. Figure 2 This is a schematic exploded view of the beam-column structure 10.

[0064] Combination Figure 1 and Figure 2 As shown, the beam-column structure 10 includes: a hollow column 100, a first beam 200, a second beam 300, and a connector 400.

[0065] Specifically, the hollow column 100 extends along the first direction X, and a notch 110 is provided on the side of the hollow column 100 facing the second direction Y, which is perpendicular to the first direction X.

[0066] The first beam 200 and the second beam 300 extend along the third direction Z. The first end 210 of the first beam 200 along the third direction Z and the second end 310 of the second beam 300 along the third direction Z are arranged opposite each other. The first end 210 of the first beam 200 and the second end 310 of the second beam 300 are both arranged in the recess 110 of the hollow column 100. The third direction Z is perpendicular to the first direction X and the second direction Y.

[0067] At least a portion of the connector 400 is disposed inside the hollow column 100, and the connector 400 includes a plurality of pins 410 and a base plate 420. The ends of the plurality of pins 410 are connected to the base plate 420. The first end 210 of the first beam 200 and the second end 310 of the second beam 300 are both provided with insertion holes 460. The plurality of pins 410 are configured to be inserted into the insertion holes 460 to connect the first beam 200 and the second beam 300.

[0068] Specifically, in this embodiment, the beam-column structure 10 includes a hollow column 100, which can have a small weight to facilitate transportation and on-site installation. The hollow column 100 extends along a first direction X, optionally, the first direction X can be vertical. The hollow column 100 may have openings at both ends in the first direction X. The shape of the hollow column 100 can be, for example, square, polygonal, or circular. As an example, Figure 1 and Figure 2 The hollow column 100 in the middle is a square hollow column.

[0069] To facilitate assembly and connection with the beam, the hollow column 100 has a notch 110 on the side facing the second direction Y, which is perpendicular to the first direction X. For example, the second direction Y can be horizontal. Alternatively, as... Figure 2 As shown, the notch 110 can be a C-shaped notch. The notch 110 is provided in three adjacent walls of the hollow column 100. Specifically, the notch 110 completely penetrates the middle wall of the three walls and partially penetrates the two opposite walls of the three walls.

[0070] Both the first beam 200 and the second beam 300 extend along a third direction Z. Optionally, this third direction Z can also be horizontal and perpendicular to the second direction Y. The first end 210 of the first beam 200 in the third direction Z and the second end 310 of the second beam 300 in the third direction Z are disposed opposite each other, and both the first end 210 of the first beam 200 and the second end 310 of the second beam 300 are disposed in the recess 110 of the hollow column 100. In some embodiments, in order to increase the structural stability of the beam-column structure 10, the first end 210 of the first beam 200 and the second end 310 of the second beam 300 can abut against each other.

[0071] At least a portion of the connector 400 is disposed inside the hollow column 100 and is used to connect the first beam 200 and the second beam 300. The connector 400 allows the first beam 200 and the second beam 300 to be stably mounted on the hollow column 100. Specifically, the connector 400 includes a plurality of pins 410 and a base plate 420, with the ends of the pins 410 connected to the base plate 420. Cooperating with the plurality of pins 410, both the first end 210 of the first beam 200 and the second end 310 of the second beam 300 are provided with insertion holes 460, and the plurality of pins 410 are configured to be inserted into the plurality of insertion holes 460, thereby connecting the first end 210 of the first beam 200 and the second end 310 of the second beam 300.

[0072] As an example, Figure 2 The connector 400 shows four pins 410, and both the first end 210 of the first beam 200 and the second end 310 of the second beam 300 are provided with two insertion holes 460. In other alternative embodiments, the connector 400 may also include other numbers of pins 410, such as two or six, etc., and this application embodiment does not specifically limit this.

[0073] Optionally, in order to ensure the reliability of the connection between the first beam 200 and the second beam 300, the length of the pin 410 can be between 400mm and 1200mm, and the diameter of the pin can be between 50mm and 150mm.

[0074] According to the technical solution of this application embodiment, in the beam-column structure 10, the first end 210 of the first beam 200 and the second end 310 of the second beam 300 are respectively disposed in the recess 110 of the hollow column 100, and the two ends of the two beams are provided with insertion holes 460, which can be matched with the pins 410 in the connector 400, so that the connector 400 can connect the two beams through the pins 410, so that the two beams are fixedly disposed in the hollow column 100, forming a beam-column structure 10 with a stable structure and better performance. At the same time, the assembly process of this beam-column structure is relatively simple, which helps to improve the construction speed of the beam-column structure and reduce the construction burden on the construction site.

[0075] See also Figure 2 As shown, in some embodiments, a reinforcing member 500 is provided inside the hollow column 100, which is attached to the inner wall of the hollow column 100 to improve the bending resistance of the hollow column 100.

[0076] Figure 3 A schematic structural diagram of a reinforcing member 500 provided in an embodiment of this application is shown.

[0077] like Figure 3 As shown, the reinforcing member 500 may include a threaded structure 510, which may extend along a first direction X and be disposed inside the hollow column 100.

[0078] Specifically, the threaded structure 510, which is matched with the notch 110 in the hollow column 100, is a two-section structure. The first threaded structure 511 can be set above the notch 110, and the second threaded structure 512 can be set below the notch 110. The lengths of the first threaded structure 511 and the second threaded structure 512 can be adapted to the length from the notch 110 to the end of the hollow column 100.

[0079] In this embodiment, the threaded structure can have high mechanical strength and toughness to effectively improve the bending resistance of the hollow column 100. As an example, the threaded structure can be made of steel or other materials with high toughness and strength.

[0080] Figure 4 A schematic structural diagram of another reinforcing member 500 provided in an embodiment of this application is shown.

[0081] like Figure 4 As shown, the reinforcing member 500 may include a plurality of reinforcing ribs 520, which are distributed along the circumferential direction C of the hollow column 100 on the inner wall of the hollow column 100.

[0082] Specifically, the multiple reinforcing ribs 520 can be manufactured on the inner wall of the hollow column 100 during the prefabrication stage. To further improve the bending resistance of the hollow column 100, the multiple reinforcing ribs can also be made of steel or other materials with high toughness and strength.

[0083] Optionally, multiple reinforcing ribs 520 arranged along the circumferential direction C of the hollow column 100 on the same plane can be grouped together, and multiple groups of reinforcing ribs 520 are distributed along the first direction X inside the hollow column 100. See also Figure 4 The multiple sets of reinforcing ribs 520 can be divided into two parts. The first part of the reinforcing ribs 520 can be set above the recess 110, and the second part of the reinforcing ribs 520 can be set below the recess 110.

[0084] In some embodiments, the hollow column 100 may have both a threaded structure 510 and multiple sets of reinforcing ribs 520 inside. Figure 5 A schematic structural diagram of the threaded structure 510 and multiple sets of reinforcing ribs 520 is shown. Figure 6 A schematic top view of the hollow column 100 is shown.

[0085] Combination Figure 5 and Figure 6 As shown, when the hollow column is a square column, the threaded structure 510 can be attached to the center of the inner wall of each side of the square column in cross-section. Multiple reinforcing ribs 520 can be provided at the corners of the square column; in some embodiments, each reinforcing rib 520 can be attached to a quarter-section area of ​​the inner wall of the square column in cross-section.

[0086] Specifically, such as Figure 6 As shown, the square hollow column 100 has a side length of L in its cross-section. The threaded structure 510 is attached to the inner wall of each side of the hollow column 100 at L / 2, and the reinforcing rib 520 is attached to the inner wall of each side of the hollow column 100 at L / 4. Optionally, the side length L of the square hollow column 100 in its cross-section can be between 500 mm and 1500 mm.

[0087] Optionally, in some embodiments, the radial dimension D1 of the threaded structure 510 can be between 20mm and 50mm, and the thickness dimension D2 of the reinforcing rib 520 can be between 25mm and 75mm. By designing the radial dimension of the threaded structure 510 and the thickness dimension of the reinforcing rib 520, the mechanical strength of the threaded structure 510 and the reinforcing rib 520 can be guaranteed, thereby playing a more reliable reinforcing role.

[0088] In this embodiment, the hollow column 100 is provided with both a threaded structure 510 and reinforcing ribs 520, which can greatly improve the bending resistance of the hollow column 100 and enhance the overall performance of the hollow column 100 and the beam-column structure 10.

[0089] Furthermore, the threaded structure 510 can cooperate with the reinforcing rib 520. That is, the threaded structure 510 is attached to the center of the inner wall of the hollow column 100 in the cross-section, while the reinforcing rib 520 is attached to 1 / 4 of the inner wall of the hollow column 100 in the cross-section. The threaded structure 510 and the reinforcing rib 520 can provide uniform and comprehensive reinforcement support to the inner wall of the hollow column 100, thereby effectively and reliably improving the bending resistance and overall performance of the hollow column 100.

[0090] Figures 7 to 9 The following are simulation diagrams of stress analysis of the reinforcing member provided in the embodiments of this application. Among them, Figure 7 This is a simulation diagram of the stress analysis of a hollow column 100 without any reinforcing elements. Figure 8 A simulation diagram of the force analysis of a threaded structure 510 inside a hollow column 100. Figure 9 A simulation diagram of the stress analysis of a hollow column 100 with reinforcing ribs 520 inside.

[0091] like Figure 7 As shown, without any reinforcing members inside the hollow column 100, the maximum stress is 0.56522 MPa.

[0092] like Figure 8 As shown, when a threaded structure 510 is installed inside the hollow column 100, the maximum stress is 0.53297 MPa.

[0093] like Figure 9 As shown, when reinforcing ribs 520 are provided inside the hollow column 100, the maximum stress is 0.53296 MPa.

[0094] Simulation results show that, compared to the case where no reinforcing elements are placed inside the hollow column 100, the maximum stress can be reduced by about 5% when the threaded structure 510 or the reinforcing rib 520 is placed inside the hollow column 100. The threaded structure 510 and the reinforcing rib 520 can effectively reduce the maximum stress of the hollow column 100, improving its structural stability and bending resistance.

[0095] In addition, by combining relevant standards or specifications in the construction field, such as the Code for Design of Concrete Structures GB 50010-2010, the Technical Specification for Post-Anchoring of Concrete Structures JGJ 145-2013, and the Standard for Design of Steel Structures GB 50017-2017, the pressure that the threaded structure 510 can withstand can be calculated using the following formula:

[0096]

[0097] Where Fi is the pressure that the threaded structure can withstand, fv is the design value of shear strength (Q235), and A ce The bearing area of ​​the end face is θ, and the angle between the plane and the force is θ. This is for the safety factor.

[0098] When the threaded structure 510 is made of carbon steel Q235, fv can be determined as 115 N / mm according to relevant standards or specifications. 2 End face bearing area A ce It is 0.02695m 2 The angle θ between the plane and the force is 45°, and the safety factor is... Given a value of 0.4, the pressure that the threaded structure 510 can withstand, calculated using the above formula, is 876.47 kN. By adding an internal threaded structure, the load-bearing capacity of the hollow column 100 at its weakest point can be increased, specifically by 876.47 kN, thereby improving the structural stability and bending resistance of the hollow column 100.

[0099] Similarly, based on the aforementioned relevant standards or specifications in the construction field, the pressure that multiple reinforcing ribs 520 can withstand can be calculated using the following formula:

[0100]

[0101] F1 = Fr × n;

[0102] Where Fr is the compressive force that a single reinforcing rib 520 can withstand, fv is the design value of shear strength (Q235), and A ce The bearing area of ​​the end face is θ, and the angle between the plane and the force is θ. For the safety factor, n is the number of reinforcing ribs, and F1 is the pressure that n reinforcing ribs 520 can withstand.

[0103] When the reinforcing rib 520 is made of carbon steel Q235, fv can be determined as 115 N / mm according to relevant standards or specifications. 2 End face bearing area A ce It is 0.0025m 2 The angle θ between the plane and the force is 45°, and the safety factor is... The value is 0.4. According to the above formula, the pressure that a single reinforcing rib 520 can withstand is 81.31 kN. By adding built-in reinforcing ribs 520, the load-bearing capacity of the hollow column 100 at weak points can be increased. The specific gain of each reinforcing rib 520 is 81.31 kN, thereby improving the structural stability and bending resistance of the hollow column 100.

[0104] Figure 10The illustration shows a schematic structural diagram of the first beam 200 and the second beam 300 provided in the embodiments of this application, as well as an enlarged schematic diagram of part A.

[0105] like Figure 10 As shown, the first end 210 of the first beam 200 has a first protrusion 211 on the side away from the connector 400 (not shown in the figure). The size of the first protrusion 211 in the first direction X gradually increases in the direction toward the hollow column 100 (not shown in the figure), or gradually increases and then tends to a fixed value.

[0106] Optionally, when the size of the first protrusion 211 gradually increases in the direction of the hollow column 100 in the first direction X, the side of the first protrusion 211 facing away from the connector 400 has an inclined structure. When the first direction X is vertical, the first protrusion 211 is provided on the lower surface of the first end 210 of the first beam 200, and the lower surface of the first protrusion 211 can be an inclined structure.

[0107] Optionally, if the dimension of the first protrusion 211 gradually increases and then tends to a fixed value in the first direction X toward the hollow column 100, the side of the first protrusion 211 facing away from the connector 400 has an arcuate structure. If the first direction X is vertical, the first protrusion 211 is provided on the lower surface of the first end 210 of the first beam 200, and the lower surface of the first protrusion 211 can be an arcuate structure.

[0108] As an example, Figure 10 The lower surface of the first protrusion 211 shown in the figure is an arc-shaped structure, which can be figuratively described as a fish belly-shaped arc-shaped structure.

[0109] Similar to the first protrusion 211 mentioned above, the second end 310 of the second beam 300 has a second protrusion 311 on the side away from the connector 400. The size of the second protrusion 311 in the first direction X gradually increases along the direction toward the hollow column 100, or gradually increases and then tends to a fixed value.

[0110] Optionally, when the dimension of the second protrusion 311 gradually increases in the direction toward the hollow column 100 in the first direction X, the side of the second protrusion 311 facing away from the connector 400 has a sloped structure. Alternatively, when the dimension of the second protrusion 311 gradually increases in the direction toward the hollow column 100 and then tends to a fixed value, the side of the second protrusion 311 facing away from the connector 400 has an arcuate structure.

[0111] When the first direction X is vertical, the second protrusion 311 is provided on the lower surface of the second end 310 of the second beam 300. The lower surface of the second protrusion 311 can be a sloped structure or an arc-shaped structure.

[0112] As an example, Figure 10 The lower surface of the second protrusion 311 shown is an arc-shaped structure, figuratively speaking, a fish-belly-shaped arc-shaped structure. The second protrusion 311 can have the same shape and size as the aforementioned first protrusion 211. Furthermore, the second protrusion 311 is mirrored in shape with the first protrusion 211.

[0113] By providing a first protrusion 211 at the first end 210 of the first beam 200 and a second protrusion 311 at the second end 310 of the second beam 300, the shear bearing capacity in the first direction X (e.g., the vertical direction) can be improved.

[0114] Specifically, in accordance with the aforementioned relevant standards or specifications in the field of construction, the shear bearing capacity of the first beam 200 with the first protrusion 211 or the second beam 300 with the second protrusion 311 can be calculated using the following formula:

[0115]

[0116] Where fv is the design value of shear strength (Q235), and s1 is the area of ​​the shear section. For safety factor, F3 is Figure 10 The shear bearing capacity of the first beam 200 or the second beam 300 shown.

[0117] When the entirety of the first beam 200 or the second beam 300 (including the first protrusion 211 or the second protrusion 311) is a carbon steel structure of Q235, fv can be determined as 115 N / mm according to relevant standards or specifications. 2 The shear section area s1 is 0.42m². 2 Safety factor Given a value of 0.4, the shear capacity F3 of the first beam 200 or the second beam 300 can be calculated to be 19320kN according to the above formula.

[0118] If the first beam 200 or the second beam 300 is a conventional beam structure, that is, if the first beam 200 or the second beam 300 does not include the first protrusion 211 or the second protrusion 311, the shear capacity of the conventional beam structure can also be calculated using the following formula:

[0119]

[0120] Where fv is the design value of shear strength (Q235), and s2 is the area of ​​the shear section. For safety factors, F4 represents the shear capacity of a conventional beam structure.

[0121] When the conventional beam structure is also made of Q235 carbon steel, fv can be determined as 115 N / mm² according to relevant standards or specifications. 2 The shear section area s2 is 0.36m². 2 Safety factor The value is 0.4. Based on the above formula, the shear capacity F4 of the conventional beam structure can be calculated to be 16560kN.

[0122] As can be seen from the above calculation process, the shear bearing capacity of the first beam 200 or the second beam 300 provided in this application embodiment is increased by 2760kN compared with the shear bearing capacity of conventional beam structures, which increases the bearing capacity of the first beam 200 or the second beam 300 at weak points, with a specific gain of 2760kN, thereby effectively improving the structural stability of the first beam 200 or the second beam 300.

[0123] Figure 11 A schematic structural diagram of a connector 400 provided in an embodiment of this application is shown.

[0124] like Figure 11 As shown, in the connector 400, an elastic member (not shown) and a latch 430 are provided inside the substrate 420. The latch 430 is equipped with a movable limiting member 440. When the limiting member 440 is provided corresponding to the latch 430, the limiting member 440 is used to limit the latch 430 inside the substrate 420.

[0125] Specifically, a groove may be provided on the side of the substrate 420 facing the second direction Y, and both the latch 430 and the elastic element are built into the groove. The elastic element may be, for example, a spring. A limiting member 440 may be provided corresponding to the latch 430. For example, the limiting member 440 is also provided at the groove and is located on the side of the latch 430 facing outward. The limiting member 440 can limit the latch 430 to be inside the groove, so that the elastic element is in a compressed state.

[0126] Figure 12 Another schematic structural diagram of the connector 400 provided in an embodiment of this application is shown.

[0127] like Figure 12 As shown, when the limiting member 440 moves, the elastic member (not shown) is used to pop out the latch 430 so that the latch 430 extends out of the base plate 420 and is attached to the first end 210 of the first beam 200 (not shown) or the second end 310 of the second beam 300 (not shown).

[0128] Specifically, in this embodiment, the limiting member 440 can move under external force (e.g., the action of an operator). When the limiting member 440 moves outside the groove where the buckle 430 is located, the limiting member 440 loses its limiting function on the buckle 430. The buckle 430 pops out of the base plate 420 under the action of the elastic member. After popping out, the buckle 430 can be attached to the first end 210 of the first beam 200 or the second end 310 of the second beam 300 to further fix the first beam 200 or the second beam 300 and improve the structural stability of the first beam 200 and the second beam 300.

[0129] Optionally, such as Figure 11 and Figure 12 As shown, in some embodiments, the limiting member 440 can be a plug rod, and the connector 400 further includes an auxiliary plate 450, to which the end of the plug rod is connected. The base plate 420 is provided with a limiting hole corresponding to the buckle 430, and the plug rod passes through the limiting hole to limit the buckle 430 as the limiting member 440.

[0130] Specifically, in this embodiment, the auxiliary plate 450 may be disposed above the substrate 420. A groove for receiving the latch 430 is formed on the side of the substrate 420, and a limiting hole is formed on the upper surface of the substrate, which can extend to the groove on the side of the substrate 420. The insert 440, which serves as a limiting member, can pass through the limiting hole and enter the groove to limit the latch 430 inside the groove.

[0131] Optionally, Figure 11 and Figure 12 As an example, four grooves are formed on the two sides of the substrate 420 facing the second direction, thus accommodating four latches 430. Corresponding to these four latches, four inserts can be connected to the auxiliary plate 450. In other alternative embodiments, the number of latches 430 accommodated on the sides of the substrate 420 may be two, six, or other numbers, and this application embodiment does not specifically limit this.

[0132] Optionally, to facilitate operation of the connector 400, handles may be provided on the base plate 420 and / or the additional plate 450, for example... Figure 11 and Figure 12 The ring handle is shown. In some embodiments, the auxiliary plate 450 has a through hole to accommodate the handle on the base plate 420, and the handle on the base plate 420 can also play a certain positioning role for the auxiliary plate 450, so that when the operator operates the auxiliary plate 450, the auxiliary plate 450 can be quickly aligned with the base plate 420, and the plug connected to the auxiliary plate 450 can be quickly inserted into the positioning hole on the base plate 420.

[0133] Through the technical solution of this application embodiment, the additional plate 450 and the insert rod in the connector 400 serve as movable limiting members 440, and can be reused in the assembly process of multiple beam-column structures 10. In addition, when the additional plate 450 and the insert rod are installed above the base plate 420, the latch 430 can be confined inside the base plate 420, thereby facilitating the transportation of the connector 400, reducing transportation costs, and reducing the possibility of damage to the latch 430 during transportation.

[0134] Return to reference Figure 1 and Figure 2 In this embodiment, the beam-column structure 10 may further include: a first diagonal brace 610 and a second diagonal brace 620. The two ends of the first diagonal brace 610 are connected to the side of the first beam 200 away from the connector 400 and the side of the hollow column 100 facing the first beam 200. The two ends of the second diagonal brace 620 are connected to the side of the second beam 300 away from the connector 400 and the side of the hollow column 100 facing the second beam 300.

[0135] Specifically, when the hollow column 100 is placed vertically, that is, when the first direction X is vertical, the first diagonal brace 610 is connected to the lower surface of the first beam 200 and the first side of the hollow column 100, and the second diagonal brace 620 is connected to the lower surface of the second beam 300 and the second side of the hollow column 100, wherein the first side and the second side are arranged opposite to each other along the third direction Z.

[0136] Figure 13 A schematic structural diagram of the first diagonal brace 610 and the second diagonal brace 620 provided in the embodiments of this application is shown.

[0137] like Figure 13 As shown, the first diagonal brace 610 includes a first diagonal brace plate 611 and a first connecting plate 612. The two end faces of the first diagonal brace plate 611 are respectively connected to the first connecting plate 612. The large surface of the first connecting plate 612 is attached to the hollow column 100 or the first beam 200. The first connecting plate 612 can be connected to the hollow column 100 or the first beam 200 via a connecting member. As an example, the first connecting plate 612 is provided with threaded holes, and the first connecting plate 612 can be connected to the hollow column 100 or the first beam 200 via a threaded connecting member.

[0138] Optionally, multiple first diagonal bracing plates 611 may be provided between each group of two first connecting plates 612. For example, as shown... Figure 1 , Figure 2 and Figure 13 As shown, two first diagonal bracing plates 611 can be set between the two first connecting plates 612 in each group.

[0139] Optionally, multiple first diagonal bracing members 610 may be provided between the hollow column 100 and the first beam 200. For example, such as... Figure 1 , Figure 2 and Figure 13 As shown, two first diagonal bracing members 610 can be installed between the hollow column 100 and the first beam 200.

[0140] Similar to the first diagonal brace 610 described above, the second diagonal brace 620 includes a second diagonal brace plate 621 and a second connecting plate 622. The relevant technical solutions for the second diagonal brace plate 621 and the second connecting plate 622 can be found in the descriptions of the first diagonal brace plate 611 and the first connecting plate 612 above, and will not be elaborated upon here.

[0141] Figure 14 and Figure 15 The following are simulation diagrams showing the force analysis of the diagonal brace provided in the embodiments of this application. Among them, Figure 14 This is a simulation diagram of the stress analysis of beam-column structure 10 without diagonal bracing. Figure 15 A simulation diagram of the stress analysis of the beam-column structure 10, which includes a first diagonal brace 610 and a second diagonal brace 620.

[0142] like Figure 14 As shown, the maximum stress is 2.7955 MPa when no diagonal bracing is provided in the beam-column structure 10.

[0143] like Figure 15 As shown, when the first diagonal brace 610 and the second diagonal brace 620 are provided in the beam-column structure 10, the maximum stress is 1.8376 MPa.

[0144] Simulation results show that, compared to the case where no diagonal bracing is provided in the beam-column structure 10, the maximum stress can be reduced by about 34% by adding the first diagonal bracing 610 and the second diagonal bracing 620 to the beam-column structure 10. The first diagonal bracing 610 and the second diagonal bracing 620 can effectively reduce the maximum stress of the beam-column structure 10 and improve the structural stability of the beam-column structure 10.

[0145] In addition, based on the aforementioned relevant standards or specifications in the construction field, the pressure that the first diagonal brace 610 and the second diagonal brace 620 can withstand can be calculated using the following formula:

[0146]

[0147] F2 = Fi × n;

[0148] Where Fi is the compressive force that a single diagonal brace can withstand, fv is the design value of shear strength (Q235), and A ce The bearing area of ​​the end face is θ, and the angle between the plane and the force is θ. For the safety factor, n is the number of diagonal bracing members, and F2 is the pressure that n diagonal bracing members can withstand.

[0149] When the diagonal bracing is made of Q235 carbon steel, fv can be determined as 115 N / mm according to relevant standards or specifications. 2 End face bearing area A ce It is 0.006m 2 The angle θ between the plane and the force is 45°, and the safety factor is... Given a value of 0.4, the pressure that a single diagonal brace can withstand can be calculated to be 195.13 kN according to the above formula. By adding diagonal braces to the beam-column structure 10, the load-bearing capacity of the beam-column structure 10 at weak points can be increased, with each diagonal brace providing a specific gain of 195.13 kN, thereby improving the overall load and structural stability of the beam-column structure 10.

[0150] Return to reference Figure 1 and Figure 2 In this embodiment of the application, the beam-column structure 10 may further include: a baffle 700, the first beam 200 and the second beam 300 are respectively located on opposite sides of the recess 110 in the hollow column 100, and the baffle 700 is fastened between the opposite sides of the recess 110.

[0151] Specifically, in this embodiment, the notch 110 is a three-sided hollow notch, having openings on opposite sides in the third direction Z and an opening on one side in the second direction Y. The first end 210 of the first beam 200 and the second end 310 of the second beam 300 are respectively disposed at the two openings of the notch 110 in the third direction Z, and the baffle 700 is fastened to the remaining opening on one side facing the second direction Y.

[0152] Optionally, the dimensions of the first beam 200 and the second beam 300 in the second direction Y may be smaller than the dimensions of the hollow column 100 in the second direction Y. After the first end 210 of the first beam 200 and the second end 310 of the second beam 300 are disposed in the recess 110, the baffle 700 is fastened to the side of the recess 110 facing the second direction Y.

[0153] Optionally, the baffle 700 may include three connected side panels, wherein opposite sides are arranged along the third direction Z and respectively abut against the first beam 200 and the second beam 300. The baffle 700 can be connected to the hollow column 100 through these opposite sides. For example, the baffle 700 is provided with threaded holes on these opposite sides, and the baffle 700 can be installed and connected to the hollow column 100 by bolts or other connecting parts.

[0154] Understandably, the shape of the baffle 700 can be adapted to the shape of the recess 110. The shape of the recess 110 can also be adapted to the shape of the first end 210 of the first beam 200 and the second end 310 of the second beam 300. For example, if the first end 210 of the first beam 200 and the second end 310 of the second beam 300 have protrusions, the lower edge of the opening of the recess 110 in the second direction Y can be recessed downwards to match the shape of the protrusions. The lower edge of the panel of the baffle 700 in the second direction Y can protrude downwards to match the shape of the recess 110.

[0155] By using the technical solution of this application embodiment, the beam-column structure 10 is used as a prefabricated product, which is assembled from hollow columns 100, first beams 200, second beams 300, connectors 400 and baffles 700, thereby improving the integration of the beam-column structure 10.

[0156] During the actual construction process, after the hollow column 100, the first beam 200, the second beam 300, the connector 400, and the baffle 700 are transported to the construction site, the first beam 200 and the second beam 300 are hoisted to a certain height, the hollow column 100 is pushed horizontally to connect with the two beams, the first beam 200 and the second beam 300 are connected by the connector 400, and then the baffle 700 is fastened into the recess 110 of the hollow column 100 to complete the assembly of the beam-column structure 10.

[0157] In some embodiments, a waterproof and breathable material may be provided at the notch 110. Optionally, in practice, the waterproof and breathable material may be attached to the notch 110 or coated onto the notch 110.

[0158] Specifically, the waterproof and breathable material is disposed at the attachment points of the recess 110 and the first beam 200, and at the attachment points of the recess 110 and the second beam 300. This waterproof and breathable material can reduce the risk of water and other liquids entering the interior of the hollow column 100 and causing corrosion to the hollow column 100, which is beneficial to further improving the reliability of the hollow column 100 and the beam-column structure 10.

[0159] By way of example and not limitation, the waterproof and breathable material includes polytetrafluoroethylene (PTFE). The thickness of this waterproof and breathable material can be approximately 0.2 mm. Furthermore, this waterproof and breathable material also possesses strong tensile strength and temperature resistance, thereby further ensuring the overall performance of the beam-column structure 10.

[0160] In some embodiments, a heat insulation layer is provided inside the hollow column 100, which can keep the hollow column 100 warm and reduce the impact of temperature on the hollow column 100.

[0161] By way of example and not limitation, the insulation layer includes rigid polyurethane. The insulation layer may have a low thermal conductivity to ensure good thermal insulation performance; for example, the thermal conductivity of the insulation layer may be less than or equal to 0.024 W / (m·K). Furthermore, the insulation layer may also have high dimensional stability, good freeze-thaw resistance, UV aging resistance, salt resistance, and oil resistance.

[0162] In some embodiments, the beam-column structure 10 may be made of shape memory alloys (SMA). Specifically, in the beam-column structure 10, at least one of the hollow column 100, the first beam 200, the second beam 300, the connector 400, the reinforcing member 500 (including the threaded structure 510 and the reinforcing rib 520), the first diagonal brace 610, the second diagonal brace 620, and the baffle 700 may be made of SMA material.

[0163] Specifically, SMA is a material composed of two or more metallic elements that exhibits shape memory effect (SME) through thermoelasticity and martensitic phase transformation and its inverse. When SMA undergoes a certain deformation (within its own allowable range), it can be deformed back to its original state by external forces such as electricity or heating.

[0164] In addition, SMA also possesses high damping and high restoring force characteristics. Specifically, SMA exhibits high damping characteristics due to the martensitic phase interface and twin interfaces, as well as the interconversion between these two interfaces. For example, the specific damping of ordinary low-carbon steel is about 6%, while the specific damping of SMA is as high as 40%. Therefore, in industrial production, it can be regarded as a high-damping vibration damping and sound-absorbing material. When the temperature of SMA increases, a transformation from martensite to austenite occurs within the alloy. Since the elastic modulus of martensite is much smaller than that of austenite, the increase in the elastic modulus of the alloy due to temperature increases, resulting in a strong restoring force, is defined as the high restoring force of SMA. This property is widely used in steel structural components to control the vibration and deformation of steel structures.

[0165] Based on the technical solution of the embodiments of this application, the beam-column structure 10 is made of SMA material, which enables the beam-column structure 10 to automatically restore its original shape after being subjected to mechanical load, thereby improving the seismic performance of the beam-column structure 10.
