Description

Technical Field

[0001] The utility model relates to the technical field of profiles, in particular to the technical field of anti-compression and wear-resistant special-shaped steel. Background Art

[0002] With the continuous improvement of China's industrialization level in recent years, the level of producing special-shaped steel in China has been greatly improved compared with that in the last century. More and more special-shaped steels related to the national economy and people's livelihood, such as special-shaped steel, which is the abbreviation of complex and special-shaped cross-section steel, belongs to a kind of special-shaped steel and is different from the simple cross-section steel. According to different processes, it can be divided into hot-rolled special-shaped steel, cold-drawn special-shaped steel, cold-bent special-shaped steel, welded special-shaped steel, etc. Usually, special-shaped steel specifically refers to hot-rolled special-shaped steel, which is different from square steel, round steel, flat steel and common-shaped hot-rolled steel. At present, traditional special-shaped steel is very easy to be bent and broken due to small section modulus or weak bearing capacity, which is not conducive to subsequent use and cannot meet people's use requirements.

[0003] To solve the problems proposed in the background art, such as the high anti-compression special-shaped steel disclosed in the publication number CN217684370U, including a special-shaped steel body, the special-shaped steel body is a flat hollow steel, both ends of the special-shaped steel body are set as conical tips, the upper end surface of the special-shaped steel body is set as a special-shaped surface, the lower end surface of the special-shaped steel body is set as a flat bottom surface, both ends of the special-shaped surface and the flat bottom surface are connected to the conical tips, and a plurality of serrated edge parts are arranged on the special-shaped surface, the flat bottom surface is a horizontal end surface. By using the flat structure and conical tips at both ends to improve the overall anti-compression performance, the two inclined surfaces of the conical tips can play a good anti-compression ability, and the arc transition treatment at the connection end of the conical tip and the flat bottom surface can provide a certain elastic support, and the special-shaped surface on the upper part of the special-shaped steel body is anti-compressive and anti-collision and not easy to deform. However, this structure still has the following deficiencies:

[0004] 1. Although this special-shaped steel can have a certain elastic support through arc transition treatment, it is relatively easy to cause the fracture of the special-shaped steel when the bearing capacity is large, resulting in poor practicability;

[0005] 2. This special-shaped steel is easy to cause wear on the surface during long-term use, resulting in a reduction in service life and being not conducive to long-term use. Summary of the Invention

[0006] The purpose of the utility model is to solve the problems in the prior art, and propose an anti-compression and wear-resistant special-shaped steel, which can improve the overall anti-compression performance of the special-shaped steel, avoid being bent and broken, and set a wear-resistant layer to avoid surface wear and extend the service life.

[0007] To achieve the above object, the present utility model provides a compression-resistant and wear-resistant special-shaped steel, which includes a first steel body, a second steel body, an elastic compression-resistant structure, support blocks, a waterproof layer, and a wear-resistant layer. The first steel body and the second steel body are of an integral structure. An elastic compression-resistant structure is arranged between the first steel body and the second steel body. A plurality of support blocks are arranged on the upper end surface of the second steel body. Waterproof layers are arranged on the outer surfaces of the first steel body and the second steel body, and a wear-resistant layer is arranged outside the waterproof layer.

[0008] Preferably, compression bumps are arranged at the four corners of the upper end surface of the first steel body, and the compression bumps are of a circular structure.

[0009] Preferably, the elastic compression-resistant structure includes spring support seats, support columns, and springs. The spring support seats are located at the four corners between the first steel body and the second steel body. The upper and lower ends of the spring support seats are respectively connected to the first steel body and the second steel body. Support columns are arranged between the spring support seats, and springs are sleeved outside the support columns.

[0010] Preferably, the support blocks are parallel to each other and arranged at equal intervals. The support blocks are of an arched structure and are strip-shaped, and the length of the support blocks is less than the lengths of the first steel body and the second steel body.

[0011] Preferably, the waterproof layer is a pure acrylic polymer waterproof coating.

[0012] Preferably, the wear-resistant layer is a chromium white cast iron wear-resistant coating.

[0013] Preferably, the height of the support blocks is lower than the height of the elastic compression-resistant structure, and the elastic compression-resistant structure and the support blocks are used in cooperation.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By the cooperative use of the elastic compression-resistant structure and the support blocks, the present utility model can improve the overall compression resistance of the special-shaped steel. When the steel body is subjected to a large bearing capacity, first, the compression bumps disperse the pressure received, avoiding pressure concentration on the steel body. Then, the first steel body descends under the dispersed pressure, driving the elastic compression-resistant structure to descend. At this time, the springs on the elastic compression-resistant structure will receive and absorb the pressure, reducing the pressure on the first steel body. When the first steel body descends until it contacts the support blocks, since the support blocks are of an arched structure, they can transfer the pressure received downward and outward to adjacent parts, further improving the compression resistance of the steel body, preventing it from being bent or flattened, increasing practicality, and solving the problem that the steel body is prone to fracture when subjected to a large bearing capacity.

[0016] 2. By the combined use of the waterproof layer and the wear-resistant layer, the service life of the steel body can be extended. The waterproof layer can prevent the steel body from rusting when encountering moisture, and the wear-resistant layer can prevent the surface of the steel body from being worn, thus extending the service life. This solves the problem that the surface of the steel body is easily worn during long-term use, resulting in a reduced service life.

[0023] Refer to Figure 1 , a compression-resistant and wear-resistant special-shaped steel of the present utility model includes a first steel body 1, a second steel body 2, an elastic compression structure 3, a support block 4, a waterproof layer 5, and a wear-resistant layer 6. The first steel body 1 and the second steel body 2 are of an integral structure. An elastic compression structure 3 is provided between the first steel body 1 and the second steel body 2. A plurality of support blocks 4 are provided on the upper end surface of the second steel body 2. Waterproof layers 5 are provided on the outer surfaces of the first steel body 1 and the second steel body 2. A wear-resistant layer 6 is provided on the outer side of the waterproof layer 5. Compression bumps 7 are provided at the four corners of the upper end surface of the first steel body 1. The compression bumps 7 are of a circular structure. By providing the compression bumps 7 at the four corners of the upper end surface of the first steel body 1, the pressure received can be dispersed first, avoiding the pressure from concentrating on the first steel body 1.

[0024] Refer to Figure 2, a compression-resistant and wear-resistant special-shaped steel of the present utility model, the elastic compression-resistant structure 3 includes a spring support seat 31, a support column 32, and a spring 33. The spring support seats 31 are located at the four corners between the first steel body 1 and the second steel body 2. The upper and lower ends of the spring support seat 31 are respectively connected to the first steel body 1 and the second steel body 2. A support column 32 is arranged between the spring support seats 31, and a spring 33 is sleeved outside the support column 32. By setting the elastic compression-resistant structure 3, the pressure received can be absorbed and the pressure can be reduced.

[0025] Refer to Figure 3 , a compression-resistant and wear-resistant special-shaped steel of the present utility model, the support blocks 4 are arranged parallel to each other and at equal intervals.

The height of the support blocks 4 is lower than the height of the elastic compression-resistant structure 3, and the elastic compression-resistant structure 3 and the support blocks 4 are used in cooperation. When the first steel body 1 is subjected to a dispersed pressure and descends, it drives the elastic compression-resistant structure 3 to descend. At this time, the spring 33 on the elastic compression-resistant structure 3 will absorb the pressure, reducing the pressure received by the first steel body 1. When the first steel body 1 descends under force until it contacts the support block 4, due to the arched structure of the support block 4, the pressure received can be transmitted downward and outward to adjacent parts, further improving the compression resistance of the steel body, avoiding being bent or flattened, and increasing the practicality.

[0026] Refer to Figure 4 , a compression-resistant and wear-resistant special-shaped steel of the present utility model, the waterproof layer 5 is a pure acrylic polymer waterproof coating, and the wear-resistant layer 6 is a chromium white cast iron wear-resistant coating. By the cooperation of the waterproof layer 5 and the wear-resistant layer 6, the service life of the steel body can be extended. The waterproof layer 5 can prevent the steel body from rusting when encountering moisture, and the wear-resistant layer 6 can prevent the surface of the steel body from being worn, extending the service life.

[0027] Working process of the present utility model:

[0028] In the working process of a compression-resistant and wear-resistant special-shaped steel of the present utility model, when the steel body is subjected to a large bearing capacity, first, the compression bumps 7 disperse the pressure received, avoiding the pressure concentrating on the steel body. Then, the first steel body 1 is subjected to the dispersed pressure and descends, driving the elastic compression-resistant structure 3 to descend. At this time, the spring 33 on the elastic compression-resistant structure 3 will absorb the pressure, reducing the pressure received by the first steel body 1. When the first steel body 1 descends under force until it contacts the support block 4, due to the arched structure of the support block 4, the pressure received can be transmitted downward and outward to adjacent parts, further improving the compression resistance of the steel body, avoiding being bent or flattened, and increasing the practicality. By the cooperation of the waterproof layer 5 and the wear-resistant layer 6, the service life of the steel body can be extended. The waterproof layer 5 can prevent the steel body from rusting when encountering moisture, and the wear-resistant layer 6 can prevent the surface of the steel body from being worn, extending the service life.
