Description

Technical Field

[0001] This utility model relates to the field of steel-wood beam and column technology, and in particular to a lightweight steel-wood composite beam and column connection node. Background Technology

[0002] Currently, steel-wood composite beams and columns refer to building components that combine steel and wood using bolts or adhesives to form a synergistic load-bearing structure. The steel provides tensile and compressive strength, while the wood ensures bending stiffness and damping effect, offering advantages such as lightweight yet high strength, easy construction, and environmental friendliness.

[0003] Existing prefabricated steel-wood composite beam-column joints generally use steel filler plates and bolt connections, which requires extensive drilling into the steel filler plates. This drilling damages the timber structure, causing initial damage, and the numerous bolt connections are inconvenient. Therefore, existing prefabricated steel-wood composite beam-column joints have created weak points due to the large number of bolt holes, resulting in low structural strength at the joint locations and complex on-site assembly processes.

[0015] Furthermore, the width of the first web and the width of the first wing are equal to two-thirds of the long side of the rectangular cross-section of the wooden column.

[0016] Furthermore, the width of the second wing plate is equal to the width of the first web plate; the H-shaped steel column is glued and / or riveted to the two wooden columns respectively, and the second web plate is glued and / or riveted to the wooden board.

The connector 3 is fixed between the steel-wood composite column 1 and the steel-wood composite beam 2. The steel-wood composite column 1 includes an H-shaped steel column 11 and two wooden columns 12. The H-shaped steel column 11 includes a first web plate 111 and two first wing plates 112 that are fixedly connected. The two wooden columns 12 are fixedly installed on both sides of the first web plate 111. Two slots 121 are opened on the inner side of the wooden columns 12, and the slots 121 are engaged with the first wing plates 112.

[0042] The steel-wood composite beam 2 includes an H-shaped steel beam 21 and two wooden planks 22. The H-shaped steel beam 21 includes a second web 211 and two second wing plates 212 that are fixedly connected. The two wooden planks 22 are respectively fixedly installed on the outer side of the second wing plates 212. One end of the H-shaped steel column 11 protrudes relative to the wooden column 12 to form a male head 13, and the other end of the H-shaped steel column 11 is recessed relative to the wooden column 12 to form a female head 14. The male head 13 of the steel-wood composite column 1 is inserted into the female head 14 of the adjacent steel-wood composite column 1 along the height direction. The male head 13 has a node 15. The connector 3 is set at the corresponding node 15 of the H-shaped steel column 11 and fixedly connected to the H-shaped steel beam 21. The end of the wooden column 12 is pressed against the wooden plank 22.

[0043] This lightweight steel-wood composite beam-column connection node adopts a design consisting of a steel-wood composite column 1, a steel-wood composite beam 2, and a connector 3. The connector 3 is fixed between the steel-wood composite column 1 and the steel-wood composite beam 2. The steel-wood composite column 1 includes an H-shaped steel column 11 and two wooden columns 12. The two wooden columns 12 are connected to the first flange 112 of the H-shaped steel column 11 via their slots 121. The steel-wood composite beam 2 includes an H-shaped steel beam 21 and two wooden planks 22. The two wooden planks 22 are fixedly installed on the outer side of the second flange 212. By combining the H-shaped steel and the wood, the material properties of each can be fully utilized, playing a synergistic role in bearing the load and improving the load-bearing capacity, bending resistance, and shear resistance of the beam-column connection node.

[0044] In this design, one end of the H-shaped steel column 11 protrudes relative to the wooden column 12 to form a male head 13, while the other end of the H-shaped steel column 11 is recessed relative to the wooden column 12 to form a female head 14. Along the height direction, the male head 13 of the steel-wood composite column 1 is inserted into the female head 14 of the adjacent steel-wood composite column 1, and the male head 13 has a node portion 15. During installation, inserting the male head 13 into the female head 14 achieves the positioning connection between the columns. The connector 3 is located at the corresponding node portion 15 of the H-shaped steel column 11 and is fixedly connected to the H-shaped steel beam 21. Only the connector 3 is needed to effectively connect the node portion 15 of the steel-wood composite column 1 to the steel-wood composite beam 2, eliminating the need for on-site opening operations. The end of the wooden column 12 is press-fitted with the wooden board 22, forming a reliable force transmission path between the wooden board 22 of the steel-wood composite beam 2 and the wooden column 12 of the steel-wood composite column 1, ensuring the structural stability of the connection node between the steel-wood composite beam 2 and the column.

[0045] Furthermore, the steel-wood composite column 1 and steel-wood composite beam 2 adopt standardized size design, which facilitates mass production in the factory according to standard dimensions. On-site assembly requires no on-site processing. The connection component 3 simplifies the assembly operation of the H-shaped steel column 11 and H-shaped steel beam 21, ensuring the reliability of force transmission between the steel-wood composite beam 2 and the steel-wood composite column 1, and effectively resisting external forces such as seismic loads. It effectively avoids the formation of weak points due to numerous bolt holes, resulting in high structural strength at the joints and a simple on-site assembly process.

[0046] In this embodiment, the connector 3 is an angle steel. The steel-wood composite beam 2 is connected to the side of the first web 111, and the connector 3 is fixed at the angle between the first web 111 and the second web 211. The steel-wood composite beam 2 is also connected to the side of the first flange 112, and the connector 3 is fixed at the angle between the first flange 112 and the second web 211. The connector 3 allows the second web 211 of the steel-wood composite beam 2 to be fixed to both sides of the first web 111 of the steel-wood composite column 1. The connector 3 also allows the second web 211 of the steel-wood composite beam 2 to be fixed to the outer side of the first flange 112 of the steel-wood composite column 1, thus satisfying the connection requirements between the steel-wood composite beam 2 and the steel-wood composite column 1 in four horizontal directions.

[0047] like Figure 4 As shown, the connector 3 has a first bolt hole 31 and a second bolt hole 32, with the axis of the first bolt hole 31 and the axis of the second bolt hole 32 arranged perpendicularly; the first web plate 111 has a first connecting hole 113 at the node 15, and the end of the second web plate 211 has a second connecting hole 213.

Bolts 33 are installed in the first bolt hole 31 and the third connecting hole 114, and bolts 33 are installed in the second bolt hole 32 and the second connecting hole 213.

[0048] As a further preferred embodiment, both wooden columns 12 have rectangular cross-sectional profiles, with the widths of the first web 111 and the first flange 112 being smaller than the longer side of the rectangular cross-section of the wooden column 12. Specifically, the widths of the first web 111 and the first flange 112 are equal to two-thirds of the longer side of the rectangular cross-section of the wooden column 12. That is, the cross-sectional dimensions of the wooden column 12 are larger than those of the H-shaped steel column 11, allowing the wooden column 12 to completely enclose the H-shaped steel column 11, ensuring both the aesthetics and load-bearing capacity of the steel-wood composite column 1.

[0049] It should be noted that the width of the second flange 212 is equal to the width of the first web 111. During installation, the H-shaped steel beam 21 of the steel-wood composite beam 2 can be smoothly inserted into the inside of the H-shaped steel column 11 of the steel-wood composite column 1, ensuring a tight and reliable connection between the steel-wood composite beams 2 and 11. The H-shaped steel column 11 is glued and / or riveted to the two wooden columns 12 respectively, and the second web 211 is glued and / or riveted to the wooden board 22, ensuring a firm bond between the H-shaped steel and the wood.

[0050] Furthermore, each of the two wooden columns 12 has a first through hole 122 corresponding to the female end 14. The axis of the first through hole 122 is arranged perpendicular to the first web 111. The first web 111 has a second through hole 115 corresponding to the male end 13. Bolts 33 are connected through the first through hole 122 and the second through hole 115. When connecting the columns, the male end 13 of the first layer steel-wood composite column 1 is inserted into the female end 14 of the second layer steel-wood composite column 1. The first through hole 122 of the wooden column 12 is aligned with the second through hole 115 of the first web 111, and the assembly connection between the columns is achieved by bolts 33. In addition, the web of the H-beam foundation 4 has a third through hole 41, and bolts 33 are connected through the first through hole 122 of the two wooden columns 12 of the first layer steel-wood composite column 1.

[0051] In this embodiment, the lightweight steel-wood composite beam-column connection node also includes an H-shaped steel foundation 4. The H-shaped steel foundation 4 is fitted with the female head 14 of the first-layer steel-wood composite column 1. The reserved height of the H-shaped steel foundation 4 is L3; the height of the H-shaped steel column 11 is L1, the height of the wooden column 12 is L2, the depth of the female head 14 of the steel-wood composite column 1 is h1, the height of the second web 211 is h2, the thickness of the second flange 212 is t1, and the thickness of the wooden board 22 is t2, satisfying: L1+L3=L2+h1+h2+2t1+t2. The H-shaped steel column 11 and the wooden column 12 of the first-layer steel-wood composite column 1 are adaptively designed, which not only reserves the required dimensions of the male head 14 and its node part 15 at the upper end of the first-layer H-shaped steel column 11, but also ensures that the female head 14 at the lower end of the first-layer wooden column 12 can form an accurate insertion connection with the H-shaped steel foundation 4.

[0052] In other embodiments, if the insertion requirements of the steel-wood composite column 1 and the H-beam foundation 4 are not considered, the height of the H-beam column 11 is L1, the height of the wooden column 12 is L2, the depth of the female head 14 of the steel-wood composite column 1 is h1, the height of the second web 211 is h2, the thickness of the second flange 212 is t1, and the thickness of the wooden board 22 is t2, satisfying: L1=L2+h1+h2+2t1+t2. When the first layer of steel-wood composite column 1 and the second layer of steel-wood composite column 1 are inserted, the part of the male head 13 between the first layer of wooden column 12 and the second layer of wooden column 12 is the node 15, ensuring that the steel-wood composite beam 2 can be accurately inserted into the node 15 between the two layers of wooden columns 12.

[0053] The assembly process of this lightweight steel-wood composite beam-column connection node is as follows:

[0054] S1. The steel-wood composite column 1, consisting of H-shaped steel column 11 and two wooden columns 12, is inserted into the H-shaped steel foundation 4 on the concrete foundation and fixed with bolts 33, forming the first-level assembly structure.
