Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically relating to a prefabricated aluminum-wood composite beam-column joint structure. Background Technology

[0002] With the development of the construction industry, prefabricated buildings have received widespread attention due to their advantages such as fast construction speed and environmental protection. In prefabricated buildings, beam-column joints are the main load-bearing components in the frame structure, and their performance is crucial to the stability and safety of the entire building.

[0003] While traditional timber-framed buildings offer advantages such as low carbon footprint, environmental friendliness, and renewability, pure timber structures suffer from insufficient strength and poor corrosion resistance, making it difficult to meet the high-performance requirements of modern architecture. Existing steel-timber composite beam-column joints, while mitigating some of the shortcomings of timber structures, still exhibit drawbacks such as poor corrosion resistance, large weight, and low strength. These issues limit their widespread application in prefabricated buildings. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a prefabricated aluminum-wood composite beam-column joint structure, which solves the problems of poor corrosion resistance, large weight, and low strength in existing wood structures or steel-wood composite beam-column joints.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A prefabricated aluminum-wood composite beam-column joint structure is provided, including an aluminum-wood composite column. The aluminum-wood composite column includes an upper wooden strip segment, a lower wooden strip segment, an upper aluminum alloy strip segment, a middle aluminum alloy strip segment, and a lower aluminum alloy strip segment. The upper wooden strip segment is connected to the upper aluminum alloy strip segment, the lower wooden strip segment is connected to the lower aluminum alloy strip segment, and the middle aluminum alloy strip segment is used to connect the upper and lower wooden strip segments. Both the upper and lower wooden strip segments include four layers of wooden strips, both the upper and lower aluminum alloy strip segments include three layers of aluminum alloy strips, and the middle aluminum alloy strip segment includes two layers of aluminum alloy strips. The aluminum alloy strips and wooden strips are alternately stacked and connected. Aluminum-wood composite beams are vertically connected to aluminum-wood composite columns. The aluminum-wood composite beams consist of four layers of wood strips and three layers of aluminum alloy strips, with the wood strips and aluminum alloy strips being alternately stacked and connected. A cross-shaped connector is provided in the weak axis direction of the aluminum-wood composite column and in the middle of the middle section of the aluminum alloy strip. The cross-shaped connector includes a vertically intersecting filler plate and a first insert plate. The T-shaped connector is located in the strong axis direction of the aluminum-wood composite column and between the aluminum-wood composite column and the aluminum-wood composite beam. The T-shaped connector includes a base plate and a second insert plate. The second insert plate is vertically connected to the base plate, the base plate is connected to the side of the aluminum-wood composite column, and the second insert plate is connected to the aluminum-wood composite beam.

[0006] The beneficial effects of adopting the above technical solution are as follows: The prefabricated aluminum-wood composite beam-column joint structure is composed of aluminum alloy and Xinjiang poplar wood. Through the synergistic use of aluminum-wood composite columns, aluminum-wood composite beams, cross-shaped connectors and T-shaped connectors, not only is the corrosion resistance of the joint improved and the weight of the joint reduced, but the connection strength and stability of the joint are also improved. Moreover, it is easy to process, simple to install, and has a small structural self-weight. By utilizing the reasonable combination and joint stress of aluminum alloy materials and wood, the problems of poor corrosion resistance, large weight and low strength of existing wood structure or steel-wood composite beam-column joints are solved. The aluminum-wood composite column consists of an upper section of wood strips, a lower section of wood strips, an upper section of aluminum alloy strips, a middle section of aluminum alloy strips, and a lower section of aluminum alloy strips. The overlapping connection between the aluminum alloy strips and wood strips not only improves the corrosion resistance of the joints but also reduces their weight, while maintaining high strength, ensuring the stability and strength of the entire aluminum-wood composite column. The aluminum-wood composite beam consists of four layers of wood strips and three layers of aluminum alloy strips, alternately stacked and connected. The aluminum-wood composite beams and columns are vertically connected, forming a stable frame structure and improving the overall load-bearing capacity of the structure. The cross-shaped connectors are located in the weak axis direction of the aluminum-wood composite column and in the middle of the aluminum alloy strip section. They are connected to the aluminum-wood composite column and aluminum-wood composite beam through perpendicularly intersecting filler plates and the first insert plate. This not only enhances the connection strength of the joint but also improves the shear resistance of the joint, significantly improving the load-bearing capacity of the aluminum-wood composite beam-column joint in the weak axis direction. The T-shaped connectors are located in the strong axis direction of the aluminum-wood composite column and between the aluminum-wood composite column and the aluminum-wood composite beam. They are connected to the aluminum-wood composite column and aluminum-wood composite beam through the bottom plate and the second insert plate, improving the connection strength and stability of the joint in the strong axis direction.

[0007] Furthermore, the ends of the aluminum-wood composite beams are provided with notches.

[0008] Furthermore, the length of the notch is less than the lengths of the first insert plate and the second insert plate.

[0009] The beneficial effects of adopting the above technical solution are as follows: the notch can accurately connect the aluminum-wood composite beam and the first insert plate of the cross-shaped connector and the second insert plate of the T-shaped connector, thereby increasing the friction of the connection and improving the connection strength. Moreover, the length of the notch is less than the length of the first and second insert plates, ensuring that the connector can be fully inserted into the notch and form a stable mechanical connection with the aluminum-wood composite beam, avoiding gaps between the connector and the aluminum-wood composite beam, thereby improving the stability and load-bearing capacity of the joint.

[0010] Furthermore, the wooden strips and aluminum alloy strips are connected by fastening bolts.

[0011] The beneficial effects of adopting the above technical solution are as follows: by tightening the bolts, a tight connection can be formed between the wooden strip and the aluminum alloy strip, avoiding relative sliding or displacement between the wooden strip and the aluminum alloy strip, significantly improving the connection strength and stability of the beam-column joint, and facilitating disassembly and replacement, thus reducing maintenance costs and time.

[0012] Furthermore, fixing holes are provided on the upper wooden strip section, the lower wooden strip section, the upper aluminum alloy strip section, the middle aluminum alloy strip section, the lower aluminum alloy strip section, and the aluminum-wood composite beam. The upper wooden strip section is connected to the upper aluminum alloy strip section, and the lower wooden strip section is connected to the lower aluminum alloy strip section by fastening bolts. The middle aluminum alloy strip section is connected to the upper wooden strip section, the lower wooden strip section, and the base plate by high-strength bolts.

[0013] The beneficial effects of adopting the above technical solution are as follows: By setting fixing holes on the upper wooden strip section, lower wooden strip section, upper aluminum alloy strip section, middle aluminum alloy strip section, and lower aluminum alloy strip section, and connecting them with fastening bolts and high-strength bolts, the connection stability between the various parts of the beam-column joint can be ensured, avoiding the problem of loosening or failure of the connection due to material expansion, contraction, or uneven stress, thereby improving the connection reliability and stability of the joint; In addition, by connecting the middle aluminum alloy strip section with the upper wooden strip section, lower wooden strip section, and base plate with high-strength bolts, the load-bearing capacity of the joint can be significantly improved.

[0014] Furthermore, the first and second insert plates are connected to the aluminum-wood composite beam by high-strength bolts.

[0015] The beneficial effects of adopting the above technical solution are as follows: connecting the first and second insert plates to the aluminum-wood composite beam with high-strength bolts can form a stable mechanical connection between the insert plates and the aluminum-wood composite beam, preventing relative displacement or deformation of the nodes during external forces such as earthquakes and wind loads, thereby significantly improving the connection strength.

[0016] Furthermore, the filler plate and the aluminum alloy strip of the middle section are set on the same plane.

[0017] The beneficial effects of adopting the above technical solution are as follows: the coplanar setting of the filler plate and the aluminum alloy strip plate in the middle section ensures the flatness of the beam-column joint connection, reduces the occurrence of stress concentration, and allows the load to be distributed more evenly on the joint, thereby improving the load-bearing capacity and stability of the joint; at the same time, the coplanar setting makes the contact between the filler plate and the aluminum alloy strip plate closer, which helps to improve the friction and anti-slip ability of the connection, thereby enhancing the connection tightness of the joint, making it less likely to experience relative displacement or detachment when subjected to external forces, and improving the connection stability and safety of the joint.

[0018] Furthermore, the width of the base plate is consistent with the cross-sectional width of the aluminum-wood composite column.

[0019] The beneficial effects of adopting the above technical solution are as follows: the width of the base plate is consistent with the cross-sectional width of the aluminum-wood composite column, which ensures that the base plate of the T-shaped connector can be completely fitted to the side of the aluminum-wood composite column, ensuring the contact area of ​​the connection part, improving the stability and reliability of the connection, and making it less likely to undergo relative displacement or deformation when subjected to external loads, thus ensuring the overall stability of the beam-column joint.

[0020] Furthermore, the thickness of the first and second insert plates is consistent with the thickness of the intermediate layer of the aluminum alloy strips in the aluminum-wood composite beam.

[0021] The beneficial effects of adopting the above technical solution are as follows: when the thickness of the first insert plate and the second insert plate is the same as the thickness of the middle layer of the aluminum alloy strip of the aluminum-wood composite beam, the stress at the connection is more uniform, which helps to reduce stress concentration, improve the load-bearing capacity and stability of the connection, and also helps to enhance the stiffness of the node, improve the deformation resistance of the node under stress, and has better stability and safety.

[0022] In summary, the prefabricated aluminum-wood composite beam-column joint structure provided by this utility model has the following advantages: In this prefabricated aluminum-wood composite beam-column joint structure, the aluminum-wood composite columns and beams are constructed by alternating layers of Xinjiang poplar wood strips and aluminum alloy strips. The aluminum alloy has good ductility and toughness, which can absorb and disperse energy under external forces such as earthquakes, reducing structural damage. The Xinjiang poplar wood has a low modulus of elasticity, which can provide a certain degree of resistance to deformation during earthquakes, thus significantly improving the load-bearing capacity of the beam-column joint. The cross-shaped connectors and T-shaped connectors are connected to the aluminum-wood composite columns and beams with high-strength bolts, which improves the connection strength and stability of the joint. In addition, the main components of the aluminum-wood composite columns and beams are made of sheet metal, which is easy to cut, drill and assemble, reducing the processing difficulty and cost. Moreover, the prefabricated assembly method makes on-site installation simpler and faster, reducing the construction period and labor costs. Attached Figure Description

For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0025] Example 1 like Figures 1-8As shown, the prefabricated aluminum-wood composite beam-column joint structure provided by this utility model includes an aluminum-wood composite column 1, an aluminum-wood composite beam 2, a cross-shaped connector 3, and a T-shaped connector 4. The aluminum-wood composite beam 2 is perpendicularly connected to the aluminum-wood composite column 1. The cross-shaped connector 3 is located in the weak axis direction of the aluminum-wood composite column 1, and the T-shaped connector 4 is located in the strong axis direction of the aluminum-wood composite column 1. This prefabricated aluminum-wood composite beam-column joint structure is made of aluminum alloy and wood. Through the synergistic use of the aluminum-wood composite column 1, aluminum-wood composite beam 2, cross-shaped connector 3, and T-shaped connector 4, not only is the corrosion resistance of the joint improved and the weight of the joint reduced, but the connection strength and stability of the joint are also improved. Moreover, it is easy to process, simple to install, and has a small structural weight. By utilizing the reasonable combination and joint stress of aluminum alloy materials and wood, it solves the problems of poor corrosion resistance, large weight, and low strength of existing wood structures or steel-wood composite beam-column joints.

[0026] like Figure 1 and Figure 5 As shown, the aluminum-wood composite column 1 includes an upper wooden strip section 11, a lower wooden strip section 12, an upper aluminum alloy strip section 13, a middle aluminum alloy strip section 14, and a lower aluminum alloy strip section 15. Each of the upper wooden strip section 11, lower wooden strip section 12, upper aluminum alloy strip section 13, middle aluminum alloy strip section 14, and lower aluminum alloy strip section 15 has fixing holes. The upper wooden strip section 11 and the upper aluminum alloy strip section 13 are connected by fastening bolts 6, and the lower wooden strip section 12 and the lower aluminum alloy strip section 15 are also connected by fastening bolts 6. The middle aluminum alloy strip section 14 connects the upper wooden strip section 11 and the lower wooden strip section 12, and is connected to the upper wooden strip section 11, the lower wooden strip section 12, and the base plate 41 by high-strength bolts 5. Section 11 and lower wooden strip section 12 each include four layers of wooden strips 16, upper aluminum alloy strip section 13 and lower aluminum alloy strip section 15 each include three layers of aluminum alloy strips 17, and middle aluminum alloy strip section 14 includes two layers of aluminum alloy strips 17. The aluminum alloy strips 17 and wooden strips 16 are alternately stacked and connected, and the wooden strips 16 and aluminum alloy strips 17 are connected by fastening bolts 6. The aluminum-wood composite column 1 is composed of upper wooden strip section 11, lower wooden strip section 12, upper aluminum alloy strip section, middle aluminum alloy strip section 14 and lower aluminum alloy strip section 15. The mutual stacking and connection between aluminum alloy strips 17 and wooden strips 16 not only improves the corrosion resistance of the joint, but also reduces the weight of the joint, while having high strength, ensuring the stability and strength of the entire aluminum-wood composite column 1.

[0027] like Figure 1 , Figure 2 and Figure 6As shown, the aluminum-wood composite beam 2 includes four layers of wood strips 16 and three layers of aluminum alloy strips 17, which are alternately stacked and connected. The aluminum-wood composite beam 2 is formed by the alternating stacking and connection of four layers of wood strips 16 and three layers of aluminum alloy strips 17, and the wood strips 16 and aluminum alloy strips 17 are connected by fastening bolts 6. The aluminum-wood composite beam 2 and the aluminum-wood composite column 1 are vertically connected to form a stable frame structure, which improves the load-bearing capacity of the entire structure. At the same time, the length of the second layer of aluminum alloy strips 17 in the aluminum-wood composite beam 2 is less than the length of the first layer of aluminum alloy strips 17 and the third layer of aluminum alloy strips 17, and a notch can be formed at the end of the aluminum-wood composite beam 2. The length of the notch is less than the length of the first insert plate 32 and the second insert plate 42. The notch allows for precise connection between the aluminum-wood composite beam 2, the first insert plate 32 of the cross-shaped connector 3, and the second insert plate 42 of the T-shaped connector 4, thereby increasing the friction at the connection point and improving the connection strength. Furthermore, the length of the notch is less than the lengths of the first insert plate 32 and the second insert plate 42, ensuring that the connector can be fully inserted into the notch and form a stable mechanical connection with the aluminum-wood composite beam 2. This avoids gaps between the connector and the aluminum-wood composite beam 2, thus improving the stability and load-bearing capacity of the joint.

[0028] like Figure 5 and Figure 7 As shown, the cross-shaped connector 3 is an integrally formed steel plate structure, which is located in the middle of the middle section aluminum alloy strip 14. The cross-shaped connector 3 includes a vertically intersecting filler plate 31 and a first insert plate 32.

The cross-shaped connector 3 is located in the weak axis direction of the aluminum-wood composite column 1 and in the middle of the middle section aluminum alloy strip 14. It is connected to the aluminum-wood composite column 1 and the aluminum-wood composite beam 2 by the vertically intersecting filler plate 31 and the first insert plate 32. This not only enhances the connection strength of the node, but also improves the shear resistance of the node, and significantly improves the load-bearing capacity of the aluminum-wood composite beam 2 column node in the weak axis direction.

[0029] like Figure 5 and Figure 8As shown, the T-shaped connector 4 is disposed between the aluminum-wood composite column 1 and the aluminum-wood composite beam 2. The T-shaped connector 4 includes a base plate 41 and a second insert plate 42. The second insert plate 42 is vertically connected to the base plate 41 by welding. The base plate 41 is connected to the side of the aluminum-wood composite column 1. The width of the base plate 41 is consistent with the cross-sectional width of the aluminum-wood composite column 1. The second insert plate 42 is connected to the aluminum-wood composite beam 2 by high-strength bolts 5, and the thickness of the second insert plate 42 is consistent with the thickness of the middle layer of the aluminum alloy strip plate 17 of the aluminum-wood composite beam 2. The T-shaped connector 4 is disposed in the strong axis direction of the aluminum-wood composite column 1 and between the aluminum-wood composite column 1 and the aluminum-wood composite beam 2. The connection between the base plate 41 and the second insert plate 42 and the aluminum-wood composite column 1 and the aluminum-wood composite beam 2 improves the connection strength and stability of the node in the strong axis direction.

[0030] like Figure 1 and Figure 3 As shown, the wooden strip 16 and the aluminum alloy strip 17 are connected by fastening bolts 6. The fastening bolts 6 can form a tight connection between the wooden strip 16 and the aluminum alloy strip 17, avoiding relative sliding or displacement between the wooden strip 16 and the aluminum alloy strip 17, which significantly improves the connection strength and stability of the beam-column joint, and facilitates disassembly and replacement, reducing maintenance costs and time.

[0031] Example 2 In this embodiment, the prefabricated aluminum-wood composite beam-column joint structure is composed of alternating layers of Xinjiang poplar wood strips 16 and aluminum alloy strips 17.

Then, drill the positions of fixing holes on the four layers of Xinjiang poplar wood strips 16 and aluminum alloy strips 17 in the aluminum-wood composite beam 2 using a drilling machine. The diameter of the fixing hole at the end of the aluminum-wood composite beam 2 furthest from the assembly end is 8mm. The diameter of the fixing holes near the assembly end of the timber composite beam 2 is 18mm; next, fixing holes are drilled on the aluminum-wood composite column 1 using a drilling machine. The diameter of the fixing holes on the upper section 11 and lower section 12 of the aluminum-wood composite column 1, away from the assembly end, is 8mm, and the diameter of the fixing holes near the assembly end is 18mm. The diameter of the fixing holes on the upper section 13 and lower section 15 of the aluminum alloy strip is 8mm, and the diameter of the fixing holes on the middle section 14 of the aluminum alloy strip is 18mm.

Then, the Xinjiang poplar wood strips 16 and aluminum alloy strips 17 in the aluminum-wood composite column 1 and aluminum-wood composite beam 2 are stacked together and connected by M6 fastening bolts 6. The upper section of the wood strip 11 is connected to the upper section of the aluminum alloy strip 13 by M6 fastening bolts 6, and the lower section of the wood strip 12 is connected to the lower section of the aluminum alloy strip 13. The strip sections 15 are connected by M6 fastening bolts 6. The middle aluminum alloy strip section 14 is connected to the upper wooden strip section 11, the lower wooden strip section 12 and the bottom plate 41 by M16 high-strength bolts 5. The cross-shaped connector 3 and the T-shaped connector 4 are fixed to the aluminum-wood composite column 1 by M16 high-strength bolts 5. Finally, the notch at the end of the aluminum-wood composite beam 2 is connected to the first insert plate 32 and the second insert plate 42 by M16 high-strength bolts 5 to complete the assembly of the entire aluminum-wood composite beam-column joint structure.

[0032] In summary, the prefabricated aluminum-wood composite beam-column joint structure provided by this utility model, through the coordinated use of aluminum-wood composite columns 1, aluminum-wood composite beams 2, cross-shaped connections, and T-shaped connectors 4, and composed of aluminum alloy and Xinjiang poplar wood, not only improves the corrosion resistance of the joint and reduces its weight, but also enhances the connection strength and stability of the joint. Furthermore, it is easy to process, simple to install, and has a low structural weight.
