Steel and wood have certain similarities in design and construction. For example, both materials have high strength-to-weight ratio (ratio of strength to density), good elasticity, and easy processing. In addition, the construction of steel and wood components is largely factory-made and on-site hoisting and installation, which provides good conditions for the combination of the two in building structures. The flexible combination of steel and wood structures can combine the advantages of steel and wood, give play to excellent mechanical properties and architectural beauty, and produce various architectural forms, which are deeply loved by people. Especially for public buildings, steel can make architectural shapes and architectural spaces more flexible; and wood, as a traditional building material for thousands of years, always brings a sense of affinity and beauty to buildings. It is not only a structural load-bearing component, but also a natural part of architectural decoration.

[0026] Preferably, the wood beam connecting member 5 is a cross-shaped structure composed of orthogonal steel plates.

[0027] Preferably, the outer diameter of the support plate 4 is larger than the outer diameter of one end of the steel column 1 , and the support plate 4 is welded to one end of the steel column 1 .

[0028] Preferably, the outer diameter of the wood beam connecting component 5 is greater than the outer diameter of the steel column connecting component 3, and the connection between the wood beam connecting component 5 and the support plate 4 is a welding connection.

[0029] Preferably, one end of the L-shaped side plate 6 is welded to the side surface of the support plate 4 .

[0030] Preferably, the steel column 1 is a circular tube structure, the steel column connecting component 3 is a cross-shaped structure, one end of the steel column connecting component 3 away from the wooden beam connecting component 5 extends to the interior of the steel column 1, and the side of the steel column connecting component 3 is welded to the inner wall of the steel column 1.

[0031] Example 2, reference Figure 2 and Figure 4 Compared with the technical solution of Example 1, the difference is that the steel column 1 is a rectangular tube structure, the steel column connecting component 3 is a cross-shaped structure, the end of the steel column connecting component 3 away from the wooden beam connecting component 5 extends to the interior of the steel column 1, and the side of the steel column connecting component 3 is welded to the inner wall of the steel column 1.

[0032] Example 3, reference Figure 3 Compared with the technical solution of Example 1, the difference is that the cross-section of the steel column 1 is an I-shaped structure, the steel column connecting component 3 is a straight structure, and the steel column connecting component 3 is orthogonal to the web side wall of the steel column 1 and is welded and connected.

[0033] In the utility model, the support plate 4 can be used as the top cover plate of the steel column 1, and also provide temporary support for the installation of the wooden beam 2, so that the end of the wooden beam 2 is supported on the support plate 4, and the scaffolding used to support the wooden beam 2 can be omitted; when the wooden beam 2 is installed and aligned, it can be observed from the side of the L-shaped side plate 6 whether the screw hole 1 8 is aligned with the screw hole 3 10. This observation and positioning method is simple and easy to operate. After aligning the screw hole 1 8 with the screw hole 3 10, it can be ensured that the screw holes of the L-shaped side plate 6, the wooden beam 2, and the wooden beam connecting component 5 are completely aligned, and the installation bolts 7 can be inserted for rapid installation.

[0034] When in use, the steel column 1 and the wooden beam 2 can be processed and produced in the factory. The wooden beam 2 should be provided with a mounting slot 11 and a screw hole 8. The assembly connection structure disclosed in the utility model can be processed and welded in the factory, and the welding with the top of the steel column 1 can be completed in the factory. The processing process is: first weld the steel column connecting component 3 with the steel column 1, and then cover the top of the steel column 1 with the support plate 4, so that the support plate 4 is welded to the top of the steel column 1 and the steel column connecting component 3. Therefore, during on-site construction, the hoisting construction of the steel column 1 with the assembly connection structure is completed first, and then the wooden beam 2 is installed and connected with the assembly connection structure on the top of the steel column 1, thereby avoiding on-site welding and realizing rapid assembly construction.

[0035] In the utility model, the wood beam connecting component 5 and the support plate 4 enhance the bearing capacity and rigidity of the top of the steel column 1, and improve the reliability of the force of the assembly connection structure. The steel column connecting component 3 is connected to the wood beam 2 through the mounting bolt 7, which meets the force transmission requirements of the wood beam 2. When the mounting bolt 7 of the utility model transmits the shear force at the end of the wood beam 2, the mounting bolt 7 has a total of 4 shear surfaces to share the shear force, giving full play to the shear resistance of the mounting bolt 7, improving the material utilization efficiency, and saving the material usage of the mounting bolt 7.

[0036] The assembly connection structure proposed in the utility model can also transmit the axial force of the wooden beam 2, and its force transmission mechanism is similar to the shear force transmission of the wooden beam 2, that is, the axial force is transmitted by shearing the mounting bolts 7. Since the height of the cross section of the wooden beam 2 is arranged with screw holes 8, the mounting bolts 7 close to the upper and lower edges of the cross section of the wooden beam 2 can transmit the axial stress generated by the bending moment in the wooden beam 2, and the axial stress of the upper and lower edges forms a force couple, thereby achieving the effect of transmitting the bending moment in the wooden beam 2, so that the assembly connection structure has a certain bending moment transmission capacity. The L-shaped side panels 6 are located on both sides of the wooden beam 2, forming a "clamping" condition for the ends of the wooden beam 2, and constraining the torsion of the wooden beam 2, so that the assembly connection structure has a certain torque transmission capacity.

The surface of the steel and the welding part should be rust-free according to the relevant requirements of the national standards and the use requirements, and the surface should be coated with anti-corrosion and fire-proof coatings. The size, spacing and margin of the bolt holes should meet the force requirements and the relevant structural requirements in the design specifications.
