[0002] The base layer of a steel structure building is the foundation that supports the superstructure. It is constructed of concrete and other materials and serves to distribute the load, stabilize the base, and provide an installation foundation for the steel columns. The steel columns are the vertical load-bearing components of the steel structure building. They are connected to the base layer through anchor bolts and other means to transfer the load from the superstructure to the base layer. They are key components for constructing the building's framework and ensuring structural stability.

[0003] In steel structure buildings, the connection nodes between the base layer and steel columns need to effectively transfer loads. However, due to design and construction limitations, the force transmission path of some nodes is unclear and the structure needs to be improved. Under load, complex stress and insufficient deformation coordination are likely to occur, affecting the structural performance. Therefore, it is necessary to design a connection node between the base layer and steel columns of steel structure buildings. A stable structure is added at the concrete connection node between the base layer and the steel column. By adding a stable structure, the force transmission efficiency of the node can be enhanced, stress concentration can be avoided, cracking and deformation risks can be reduced, the collaborative working performance can be improved, the overall stability and durability of the structure can be enhanced, and long-term safe use can be guaranteed. Utility Model Content

[0004] The purpose of this utility model is to provide a connection node between the base layer and steel column of a steel structure building. It has the advantages of adding a stable structure at the concrete connection node between the base layer and the steel column, which can enhance the force transmission efficiency of the node, strengthen the overall stability and durability of the structure, and ensure long-term safe use, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A connection node between the base layer and steel column of a steel structure building includes a side frame. The inner cavity of the side frame is provided with multiple concrete blocks. The top of the concrete blocks is provided with four bases. The top of the four bases is welded with steel columns. Multiple reinforcing bars are embedded in the inner cavity of the concrete blocks. Multiple horizontal stirrups I are welded to the surface of the two reinforcing bars on the right side. Multiple horizontal stirrups II are welded to the surface of the two reinforcing bars on the left side. The horizontal stirrups I and II are symmetrical. Two symmetrical transverse reinforcing bars are welded to the top of the multiple reinforcing bars. Bolts are provided in the inner cavity of the concrete blocks. The bolts penetrate to the top of the bases and are fixedly connected to the bases by nuts.

[0006] Preferably, tie bars are welded to the surfaces of the two middle reinforcing bars, and the tie bars are located at the top of the first and second horizontal stirrups.

[0007] Preferably, a supporting steel bar is welded to the left side of the surface of the transverse steel bar on the front side, and the supporting steel bar is inserted into the left side of the inner cavity of the concrete block.

[0008] Preferably, a connecting steel bar is welded to the rear side of the left side of the front transverse steel bar, and a diagonal bracing steel bar is welded to the end of the connecting steel bar away from the front transverse steel bar. The end of the diagonal bracing steel bar away from the connecting steel bar is welded to the rear transverse steel bar.

[0009] Preferably, the surface of the transverse reinforcing bar located on the rear side is welded with diagonal reinforcing bars, and the surface of the bolt is fitted with a spring washer, with both sides of the spring washer tightly fitted to the concrete block and the nut respectively.

[0010] The beneficial effects of this utility model are: 1. This utility model uses the combined use of steel bars, horizontal stirrup one and horizontal stirrup two to weld two transverse steel bars to the top of the steel bars, thereby making the interior of the concrete block more solid. Finally, the concrete block is stabilized at the connection node of the base by bolts, thus achieving the purpose of adding a stable structure at the concrete connection node between the base and the steel column. By adding a stable structure, the force transmission efficiency of the node can be enhanced, the overall stability and durability of the structure can be strengthened, and the purpose of ensuring long-term safe use can be guaranteed. 2. By setting up tie bars, the tie bars serve as key components of horizontal stirrup one and horizontal stirrup two. By optimizing the connection form of the steel bars, the force transmission efficiency of local nodes is enhanced, making the load transmission more uniform and smooth. This effectively improves the overall stiffness and stability of the steel bars, horizontal stirrup one and horizontal stirrup two. During the construction stage, it can suppress the displacement and deformation of the steel bars and ensure the formation of the steel cage. 3. This utility model uses a spring washer. Through elastic deformation, the spring washer can continuously apply axial preload to the bolt to prevent it from loosening. At the same time, the beveled surface of the washer can scrape the contact surface, destroy the rust and oxide layer, increase the friction of the connection surface, enhance the anti-slip ability of the joint, and ensure the reliability of the connection.

[0013] In the following description, embodiments of the connection node between the steel structure building base and the steel column of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-5This illustration shows a connection node between the base layer and steel columns of a steel structure building according to an embodiment of the present invention. It includes a side frame 1, with multiple concrete blocks 2 arranged within the inner cavity of the side frame 1. Four bases 3 are positioned on the top of each concrete block 2, and steel columns 4 are welded to the top of each base 3. Multiple reinforcing bars 5 are embedded within the inner cavity of each concrete block 2. Multiple horizontal stirrups 6 are welded to the surfaces of the two right-side reinforcing bars 5, and multiple horizontal stirrups 7 are welded to the surfaces of the two left-side reinforcing bars 5. The horizontal stirrups 6 and 7 are symmetrical. Tie bars 8 are welded to the surfaces of the two middle reinforcing bars 5. These tie bars 8 are located at the top of the horizontal stirrups 1 and 2. As key components of the horizontal stirrups 1 and 2, the tie bars 8 optimize the connection of the reinforcing bars, enhance the force transmission efficiency of local nodes, and make the load transfer more uniform and smooth. This effectively improves the overall stiffness and stability of the reinforcing bars 5, 1, 6, and 7. During construction, this can suppress the displacement and deformation of the reinforcing bars, ensuring the formation of the reinforcing cage. The tops of the multiple reinforcing bars 5... Two symmetrical transverse reinforcing bars 9 are welded to the front transverse reinforcing bar 9. A supporting reinforcing bar 10 is welded to the left side of the surface of the front transverse reinforcing bar 9. The supporting reinforcing bar 10 is inserted into the left side of the inner cavity of the concrete block 2. A connecting reinforcing bar 11 is welded to the rear side of the left side of the front transverse reinforcing bar 9. A diagonal bracing reinforcing bar 12 is welded to the end of the connecting reinforcing bar 11 away from the front transverse reinforcing bar 9. The end of the diagonal bracing reinforcing bar 12 away from the connecting reinforcing bar 11 is welded to the rear transverse reinforcing bar 9. A bolt 14 is provided in the inner cavity of the concrete block 2. The bolt 14 passes through to the top of the base 3 and is secured by a nut. Fixedly connected to the base 3, the surface of the rear transverse steel bar 9 is welded with a diagonal steel bar 13. A spring washer 15 is fitted on the surface of the bolt 14. The two sides of the spring washer 15 are tightly fitted to the concrete block 2 and the nut, respectively. Through the setting of the spring washer 15, the spring washer 15 can continuously apply axial preload to the bolt 14 through elastic deformation, preventing the bolt 14 from loosening. At the same time, the inclined surface of the washer can scrape the contact surface, destroy the rust and oxide layer, increase the friction of the connection surface, enhance the anti-slip ability of the node, and ensure the reliability of the connection.

[0015] Working Principle: In use, this utility model firstly uses multiple steel bars 5 as vertical reinforcing bars. Horizontal stirrups 6 are welded to the surfaces of the two right-side steel bars 5, and horizontal stirrups 7 are welded to the two left-side steel bars 5, arranged symmetrically to enhance lateral restraint. Tie bars 8 are welded to the surfaces of the two middle steel bars 5 and placed on top of the stirrups to improve the overall rigidity of the steel cage. Then, two transverse steel bars 9 are symmetrically welded to the top of the steel bars 5. Supporting steel bars 10 are welded to the left side of the front transverse steel bar 9 and implanted into the left side of the foundation for positioning. The rear side of the front transverse steel bar 9 is welded to the rear transverse steel bar 9 via connecting steel bars 11 and diagonal bracing steel bars 12. Diagonal steel bars 13 are welded to the surface of the rear transverse steel bar 9 to further enhance the stability of the steel cage. Subsequently... The steel cage is placed in the corresponding position inside the side frame 1, and concrete is poured to form the concrete block 2. At the same time, it is ensured that the bolts 14 are pre-installed in the inner cavity of the concrete block 2 and exposed. After the concrete strength reaches the standard, the base 3 at the bottom of the steel column 4 is placed on the top of the concrete block 2, so that the bolts 14 pass through the base 3. Spring washers 15 are placed on the surface of the bolts 14, and the two sides of the washers are respectively attached to the concrete block 2 and the nut. The nut is tightened to complete the fixation. Throughout the process, the steel cage ensures the load-bearing capacity of the concrete block 2, and the bolts 14 and spring washers 15 ensure that the base 3 and the concrete block 2 are tightly connected, so that the load of the steel column 4 is transferred to the ground base through the base 3, bolts 14 and steel reinforcement system.

[0016] In summary: the connection node between the base layer and the steel column of this steel structure building, through the combined use of steel bar 5, horizontal stirrup 1 6, and horizontal stirrup 2 7, allows two horizontal steel bars 9 to be welded to the top of steel bar 5, thereby making the interior of the concrete block 2 more solid. Finally, the connection node between the concrete block 2 and the base 3 is stabilized by bolts 14. This achieves the goal of adding a stable structure at the concrete connection node between the base layer and the steel column. By adding a stable structure, the force transmission efficiency of the node can be enhanced, the overall stability and durability of the structure can be strengthened, and the purpose of ensuring long-term safe use can be guaranteed.
