The concrete and steel tubes are tightly connected, which effectively improves the load-bearing capacity of the concrete-tube steel column. It can give full play to the advantages of both steel and concrete materials. Concrete-tube steel columns have a very wide range of applications, covering almost all building structures that require high strength and good seismic performance.

[0003] Common steel-concrete composite columns also have some problems, such as the steel pipes being prone to denting during the processing of the concrete column, which cannot effectively increase the internal strength of the steel pipes, and it is inconvenient to limit the concrete, which can easily affect the service life of the steel-concrete composite column.

[0004] Therefore, we propose a high-strength steel-concrete composite column to improve upon the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength steel-concrete composite column to solve the problems mentioned in the background art, such as the inability to effectively increase the internal strength of the steel tube, the inconvenience of limiting the concrete, and the easy impact on the service life of the steel-concrete composite column.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength steel-concrete composite column, comprising a steel pipe body, wherein a fixing rod is provided inside the steel pipe body, and the upper and lower ends of the fixing rod are provided with reinforcing structures for supporting the interior of the steel pipe body; The reinforcing structure includes vertical rods and horizontal rods. Vertical rods are installed inside the steel pipe body. Horizontal rods are fixedly connected to the left and right sides of the vertical rods. Reinforcing blocks are fixedly connected to the outer end of the vertical rods and the left and right sides of the horizontal rods, respectively. Mounting slots are fixedly connected to the left and right sides of the upper and lower ends and the front and rear ends of the steel pipe body. Fixing rods are installed between the horizontal rods. A limit sleeve is fixedly connected to the middle end of the horizontal rods.

[0007] As a further technical solution of this utility model, the upper and lower ends of the fixing rod are embedded inside the limiting sleeve, and two sets of the vertical rod and the horizontal rod are respectively provided.

[0008] As a further technical solution of this utility model, the reinforcing block is embedded inside the mounting slot, and the vertical rod and horizontal rod are installed at the upper and lower ends inside the steel pipe body through the reinforcing block and the mounting slot.

[0009] As a further technical solution of this utility model, the left and right sides and the front and rear ends of the steel pipe body are respectively fixedly connected to the first steel bars, the outside of the first steel bars are wrapped with the second steel bars, the left and right sides of the front and rear ends of the fixing rod are fixedly connected to the reinforcing rod, and the side of the reinforcing rod near the outside is fixedly connected to the limiting frame.

[0010] As a further technical solution of this utility model, the first reinforcing bar and the reinforcing rod are provided in four sets, and the crossbar is clamped on one side of the outside of the first reinforcing bar.

[0011] As a further technical solution of this utility model, the second reinforcing bar is provided in several groups, and the second reinforcing bar is distributed in a ring at equal intervals outside the first reinforcing bar.

[0012] As a further technical solution of this utility model, the interior of the steel pipe body is filled with concrete, and a protective layer is provided on the exterior of the steel pipe body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the high-strength steel-concrete composite column not only increases the strength of the steel-concrete composite column and facilitates the support of the first reinforcing bar, but also improves the wear resistance of the steel pipe body. By setting up vertical bars, horizontal bars, reinforcing blocks, mounting slots, limiting sleeves, and fixing rods, the reinforcing blocks on the vertical bars and horizontal bars are placed inside the mounting slots, thereby allowing the horizontal bars and reinforcing blocks to be installed inside the steel pipe body to support the inner wall of the steel pipe body, increasing the internal strength of the steel pipe body and enabling it to withstand greater strength. The fixing rods are installed between the horizontal bars through the limiting sleeves, which can limit the upper and lower ends of the fixing rods. By setting up a first reinforcing bar, a limiting frame, a reinforcing rod, and a second reinforcing bar, the second reinforcing bar is wrapped around the outside of the first reinforcing bar to limit and fix the first reinforcing bar. Setting up the first and second reinforcing bars can further increase the internal strength of the steel pipe body. The limiting frame is stuck on the outside of the first reinforcing bar. The reinforcing rod supports the first reinforcing bar through the limiting frame to increase the strength of the first reinforcing bar. Setting up the second reinforcing bar, the limiting frame, and the reinforcing rod can support and limit the first reinforcing bar, preventing the first reinforcing bar from tilting when the concrete body is not filled. By incorporating a concrete core, a protective layer, polyurethane coating, and epoxy coating, the concrete core fills the interior of the steel pipe core, creating a tight connection between the two. This effectively improves the load-bearing capacity of the concrete-filled steel pipe column, making it more robust and able to withstand greater pressure and vibration, thus exhibiting better seismic performance. The polyurethane and epoxy coatings not only have good adhesion and wear resistance but also excellent weather resistance and chemical corrosion resistance, making them suitable for long-term exposure to harsh environments.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 The present invention provides an embodiment of a high-strength steel-concrete composite column, comprising a steel pipe body 1, a fixing rod 13 inside the steel pipe body 1, and a reinforcing structure for supporting the interior of the steel pipe body 1 at both the upper and lower ends of the fixing rod 13. The reinforcing structure includes vertical rods 7 and horizontal rods 8. Vertical rods 7 are installed inside the steel pipe body 1. Horizontal rods 8 are fixedly connected to the left and right sides of vertical rods 7. Reinforcing blocks 9 are fixedly connected to the end of vertical rods 7 near the outside and the left and right sides of horizontal rods 8 respectively. Installation slots 10 are fixedly connected to the left and right sides of the upper and lower ends and the front and rear ends of the steel pipe body 1 respectively. Fixed rods 13 are installed between horizontal rods 8. Limit sleeves 12 are fixedly connected to the end of horizontal rods 8 near the middle. The upper and lower ends of the fixing rod 13 are embedded inside the limiting sleeve 12. The vertical rod 7 and the horizontal rod 8 are respectively provided in two sets. The reinforcing block 9 is embedded inside the mounting slot 10. The vertical rod 7 and the horizontal rod 8 are installed at the upper and lower ends inside the steel pipe body 1 through the reinforcing block 9 and the mounting slot 10. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the reinforcing blocks 9 on the vertical rod 7 and the horizontal rod 8 are placed inside the mounting slot 10, so that the horizontal rod 8 and the reinforcing blocks 9 can be installed inside the steel pipe body 1 to support the inner wall of the steel pipe body 1, increase the internal strength of the steel pipe body 1, and enable it to withstand greater strength. The fixing rod 13 is installed between the horizontal rods 8 through the limiting sleeve 12, and the limiting sleeve 12 can limit the upper and lower ends of the fixing rod 13.

[0019] The steel pipe body 1 has first steel bars 2 fixedly connected to the left and right sides and front and rear ends, respectively. The first steel bars 2 are wrapped with second steel bars 11. The left and right sides of the front and rear ends of the fixing rod 13 are fixedly connected with reinforcing rods 6. The side of the reinforcing rod 6 closest to the outside is fixedly connected with a limit frame 5. There are four sets of first steel bars 2 and reinforcing rods 6. The crossbar 8 is clamped on the side of the first steel bar 2. There are several sets of second steel bars 11. The second steel bars 11 are distributed in a ring at equal intervals outside the first steel bars 2. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the second reinforcing bar 11 is wrapped around the outside of the first reinforcing bar 2 to limit and fix the first reinforcing bar 2. The first reinforcing bar 2 and the second reinforcing bar 11 can further increase the internal strength of the steel pipe body 1. The limiting frame 5 is stuck on the outside of the first reinforcing bar 2. The reinforcing rod 6 supports the first reinforcing bar 2 through the limiting frame 5 to increase the strength of the first reinforcing bar 2. The second reinforcing bar 11, the limiting frame 5 and the reinforcing rod 6 can support and limit the first reinforcing bar 2 to prevent the first reinforcing bar 2 from tilting when the concrete body 3 is not filled.

[0020] The interior of the steel pipe body 1 is filled with concrete body 3, and the exterior of the steel pipe body 1 is provided with a protective layer 4. The protective layer 4 includes polyurethane coating 14 and epoxy coating 15. Polyurethane coating 14 is applied to the exterior of the steel pipe body 1, and epoxy coating 15 is applied to the exterior of polyurethane coating 14. The thickness of polyurethane coating 14 and epoxy coating 15 is the same, and polyurethane coating 14 and epoxy coating 15 work together. Specifically, such as Figure 1 and Figure 4 As shown, the concrete body 3 is filled inside the steel pipe body 1, making the steel pipe body 1 and the concrete body 3 tightly connected, which effectively improves the load-bearing capacity of the steel pipe concrete column, making the steel pipe concrete column stronger and able to withstand greater pressure and vibration, and has better seismic performance. The polyurethane coating 14 and epoxy coating 15 not only have good adhesion and wear resistance, but also have excellent weather resistance and chemical corrosion resistance, making them suitable for long-term exposure to harsh environments.

[0021] Working principle: In use, the reinforcing blocks 9 on the vertical rod 7 and horizontal rod 8 are placed inside the mounting slot 10, thereby allowing the horizontal rod 8 and reinforcing blocks 9 to be installed inside the steel pipe body 1 to support the inner wall of the steel pipe body 1, increasing the internal strength of the steel pipe body 1 and enabling it to withstand greater strength. The fixing rod 13 is installed between the horizontal rods 8 through the limiting sleeve 12, which can limit the upper and lower ends of the fixing rod 13. The second reinforcing bar 11 is wrapped around the outside of the first reinforcing bar 2 to limit and fix the first reinforcing bar 2. The setting of the first reinforcing bar 2 and the second reinforcing bar 11 can further increase the internal strength of the steel pipe body 1. The limiting frame 5 is clamped on the outside of the first reinforcing bar 2, and the reinforcing rod 6 is connected to the limiting frame 10. The support frame 5 increases the strength of the first reinforcing bar 2 by supporting it. The second reinforcing bar 11, the limiting frame 5, and the reinforcing rod 6 can limit the support of the first reinforcing bar 2 and prevent it from tilting when the concrete body 3 is not filled. The concrete body 3 fills the inside of the steel pipe body 1, making the steel pipe body 1 and the concrete body 3 tightly connected, which effectively improves the load-bearing capacity of the steel pipe concrete column, making the steel pipe concrete column stronger and able to withstand greater pressure and vibration, and has better seismic performance. The polyurethane coating 14 and epoxy coating 15 not only have good adhesion and wear resistance, but also excellent weather resistance and chemical corrosion resistance, making them suitable for long-term exposure to harsh environments.
