[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] Embodiment 1

[0018] like Figure 1 and Figure 2 As shown, the construction of the steel-concrete composite structural beam 4 begins with the construction of its skeleton structure. The skeleton consists of an upper steel frame 11, a side steel frame 12 and a bottom steel plate 13. The bottom steel plate 13 serves as a foundation, and its front and rear sides are tightly connected to the two upper steel frames 11 above through multiple vertically welded side steel frames 12. In order to enhance the stability and integrity of the structure, reinforcing ribs are welded between the side steel frames 12 to resist the influence of external forces and torques.

[0019] After the skeleton structure is built, concrete is poured into the gaps of the skeleton, making it tightly combined with the steel frame to form a strong steel-concrete composite structural beam 4. This design not only retains the high strength characteristics of steel, but also utilizes the compressive properties of concrete, which significantly improves the strength and rigidity of the entire structure.

[0020] In order to improve the maintainability and service life of the structure, multiple threaded holes are processed on the front and rear surfaces of the side steel frame 12 and the bottom steel plate 13. Steel plates 5 with fixing bolts 6 matching the threaded holes are respectively assembled on the front and rear of the steel-concrete composite structural beam 4. These steel plates 5 not only enhance the bearing capacity of the structure, but also the anti-corrosion and anti-rust glaze sprayed on the surface can effectively resist the erosion of the external environment and extend the service life of the structure.

[0021] Embodiment 2

[0022] Based on the first embodiment, Figure 2 and Figure 3 As shown, the lateral support column 2 is a key component to ensure the stability of the structure under external forces such as earthquakes. It is mainly composed of a truss 9 and a concrete filling part. The truss 9 is made of high-strength steel and has excellent bearing capacity and stability. The concrete filling part is poured inside and outside the truss 9 to form a solid support structure.

[0023] The side of the truss 9 is tightly connected to the bottom steel plate 13 by welding, ensuring that the lateral support column 2 and the steel-concrete composite structural beam 4 form a whole. In order to improve the stability of the connection, a protruding bolt mounting plate 10 is integrally formed on the top of the truss 9. The end of the upper steel frame 11 is processed with threaded holes at the corresponding positions, and the limit bolts 3 matched with the bolt mounting plate 10 are sequentially assembled into the threaded holes of the bolt mounting plate 10 and the upper steel frame 11 to achieve a fixed connection between the upper steel frame 11 and the truss 9.

[0024] At the bottom of the lateral support column 2, a rubber seismic isolation bearing 1 is installed. The rubber seismic isolation bearing 1 has excellent seismic isolation performance and can effectively reduce the propagation and amplification effect of seismic waves, thereby protecting the structure from damage caused by earthquakes.

[0025] Embodiment 3

[0026] Based on the second embodiment, Figure 1 and Figure 3 As shown, in order to further improve the seismic performance of the structure, the utility model installs a viscous damper 7 on the steel-concrete composite structural beam 4. The viscous damper 7 is a device that consumes energy by using fluid viscous resistance. When an earthquake occurs, the viscous damper 7 consumes seismic energy by generating viscous resistance, thereby reducing the internal force and displacement response of the structure.

[0027] In this embodiment, the viscous damper 7 is fixed on the steel-concrete composite structural beam 4 and connected to the top floor slab 8 above through a connector. This connection method enables the viscous damper 7 to effectively participate in the overall seismic resistance system of the structure and improve the seismic resistance performance of the structure.

[0028] Embodiment 4

[0029] On the basis of Embodiments 1 to 3, Figures 1 to 3 As shown, when an earthquake occurs, seismic waves are transmitted to the structure, and the propagation and amplification effect of the seismic waves are first reduced through the seismic isolation effect of the rubber seismic isolation bearing 1. Then, the overall stability of the structure is improved through the support effect of the lateral support column 2. At the same time, the viscous damper 7 generates viscous resistance under the action of the earthquake, consumes seismic energy, and reduces the internal force and displacement response of the structure.

[0030] Through the description of the above specific implementation methods, it can be seen that the shock absorbing device of the steel-concrete composite structural beam of the utility model fully considers the stability, bearing capacity and earthquake resistance of the structure in the structural design. Through reasonable material selection and structural design, the device can effectively protect the safety of the structure under the action of external forces such as earthquakes.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
