[0021] Please see Figure 1-3 This invention provides a technical solution: a shock-absorbing and compression-resistant steel-concrete composite column, comprising a steel pipe body 1, a support plate 2, a wrapping layer 3, and a concrete layer 4. The steel pipe body 1 is generally strip-shaped with a hollow inner side. The support plate 2 is disposed inside the steel pipe body 1, and a locking block 11 is provided on the inner side of the steel pipe body 1. The locking blocks 11 are arranged opposite each other, and the locking blocks 11 are provided with locking grooves 12, in which the support plate 2 is engaged. The concrete layer 4 is formed by concrete pouring and is disposed between the steel pipe body 1 and the support plate 2. The wrapping layer 3 includes a reinforcing strip 31 and a buffer strip 32, which are spaced apart and wrap around the outside of the steel pipe body 1.

[0022] Furthermore, the steel pipe body 1 has an overall square structure, and rounded corners are provided at the four corners of the steel pipe body 1; the reinforcing strip 31 is wrapped around the outside of the four rounded corners, and the buffer strip 32 is disposed between the reinforcing strips 31.

[0023] Furthermore, the card block 11 is integrally cast with the steel pipe body 1, the card slot 12 is opened in the middle of the card block 11, and the card block 11 has inclined slopes on both sides.

[0024] Furthermore, the support plate 2 is perpendicular to the inner wall of the steel pipe body 1, and there are at least two support plates 2 arranged side by side. The length of the support plate 2 is the same as the length of the steel pipe body 1, and the ends of the two are aligned with each other.

[0025] Furthermore, through holes 21 and fastening blocks 22 are provided on the surface of the support plate 2. The through holes 21 and fastening blocks 22 are spaced apart along the length direction of the middle position of the support plate 2. The through holes 21 are square holes and the fastening blocks 22 are trapezoidal blocks.

[0026] Furthermore, a limiting piece 13 is provided on the inner side of the steel pipe body 1 at the bending part, and the limiting piece 13 is in the shape of a right-angled triangle; a connecting hole 14 is provided in the middle of the limiting piece 13, and the connecting hole 14 is a circular hole.

[0027] Furthermore, the reinforcing strip 31 is integrally cast with the steel pipe body 1, and the buffer strip 32 is made of damping rubber material. The buffer strip 32 is fixedly bonded to the surface of the steel pipe body 1 by adhesive.

[0028] Furthermore, the thickness of the buffer strip 32 is greater than the thickness of the reinforcing strip 31, and the surface of the buffer strip 32 is coated with a corrosion-resistant coating.

[0029] Working principle: In specific applications, corresponding locking blocks 11 are set on the inner side of the square steel pipe body 1. The locking slots 12 of the locking blocks 11 are aligned with each other, thereby locking the two sides of the support plate 2 and ensuring that the support plate 2 is fixedly set in the steel pipe body 1. A concrete layer 4 is formed between the steel pipe body 1 and the support plate 2 by pouring concrete, and a wrapping layer 3 is set on the outside of the steel pipe body 1.

[0030] During the pouring process, the concrete layer 4 flows through the connecting hole 14 and the through hole 21 due to the fluidity of the concrete, thus solidifying the concrete layer 4 within the steel pipe body 1 into a single unit. This concrete layer 4 wraps around the limiting plate 13 and the fastening block 22, keeping the steel pipe body 1 and the support plate 2 relatively fixed to the concrete layer 4. This increases the structural strength of the steel pipe body 1 and the support plate 2, improving the overall structural strength and ensuring proper functioning. The fastening block 22 is a trapezoidal block with inclined slopes on both sides of the locking block 11. This structure prevents voids caused by incomplete concrete filling during the concrete solidification process, ensuring complete filling of the concrete.

[0031] A wrapping layer 3, consisting of reinforcing strips 31 and buffer strips 32, is wrapped around the outside of the steel pipe body 1. The reinforcing strips 31 are wrapped around the outside of the four chamfered parts, and the buffer strips 32 are attached to the steel pipe body 1 with adhesive. The thickness of the buffer strips 32 is greater than that of the reinforcing strips 31. During a collision, the buffer strips 32 will preferentially contact the impacting object, and the deformation of the damping rubber material will alleviate the impact, thereby playing a role in buffering and shock absorption. The outer reinforcing strips 31 are integrally cast with the steel pipe body 1, which to a certain extent increases the thickness of the steel pipe body 1 and improves its strength.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
