[0002] A railway protective concrete fence column covers multiple fields such as line planning, track engineering, bridge and tunnel construction, station hub design, and signal control, and is crucial for ensuring the safety and efficiency of railway transportation. With the progress of technology, railway concrete technology is constantly evolving towards the direction of intelligent, green and sustainable development. As one of the links, the concrete fence column is also constantly innovating in material selection, structural design, production process, etc. to meet the needs of modern railway development and provide a solid guarantee for railway safety.

[0003] In the prior art, when installing the fence for some concrete columns, one side of the column is connected and stabilized with the fence using steel pipes, and then the other side of the column is installed. This installation method is time-consuming and reduces the installation efficiency. Therefore, a railway protective concrete fence column is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a railway protective concrete fence column, aiming to improve the problem that the installation of the column in the prior art is time-consuming and reduces the installation efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A railway protective concrete fence column includes two side columns. A protective component is fixedly connected to the adjacent side of the two side columns. A first wedge block is fixedly connected to the outer side of the side column. A card slot is opened at the top end of the side column. The outer part of the first wedge block is tenon-mortise connected with a column body. Two plugging components for capping are tenon-mortise connected to the inner wall top end of the column body. A clamping block is fixedly connected to the bottom end of the plugging component;

[0007] When installing the column body and the protective component, the two column bodies can be directly installed on the ground, and then the protective component and the first wedge block are slid into the inner walls of the two column bodies to form a tenon-mortise relationship, and then the plugging component is used for capping;

[0008] As a further description of the above technical solution:

[0009] The protective component includes a protective net, and both sides of the protective net are respectively fixedly connected to the adjacent side of the two side columns;

[0010] The protective net here is used to prevent the intrusion of external personnel or animals, providing a solid line of defense for railway safety;

[0011] As a further description of the above technical solution:

[0012] The blocking component includes a second wedge block, and the outer part of the second wedge block is mortise-and-tenon connected to the inner wall of the column;

[0013] The second wedge block here is used to cap the first wedge block after the first wedge block and the column form a mortise-and-tenon relationship;

[0014] As a further description of the above technical solution:

[0015] The first wedge block is trapezoidal with an outward expansion shape, and the bottom end of the second wedge block is in contact with the top end of the side column;

[0016] The outward expansion trapezoidal shape of the first wedge block here makes it not easily break away from the inner wall of the column, improving the stability;

[0017] As a further description of the above technical solution:

[0018] The outer part of the clamping block is mortise-and-tenon connected to the inner wall of the clamping groove, and the top end of the first wedge block is in contact with the bottom end of the second wedge block;

[0019] When the clamping block and the clamping groove form a mortise-and-tenon relationship, the installation of this column and the protective net is completed;

[0020] As a further description of the above technical solution:

[0021] The second wedge block is trapezoidal with an outward expansion shape, and the side column and the column are made of ultra-high performance concrete;

[0022] The special shape of the second wedge block here makes the mortise-and-tenon connection between it and the column more stable. At the same time, the side column and the column here adopt the material of ultra-high performance concrete, effectively preventing the phenomenon of concrete expansion, cracking and peeling caused by the corrosion of steel bars in reinforced concrete, improving the overall service life, and reducing the maintenance and replacement costs;

[0023] As a further description of the above technical solution:

[0024] The protective net is made of zinc-aluminum alloy coated steel wire, and the outer frame material of the protective net is carbon fiber reinforced plastic;

[0025] The protective net and its outer frame here adopt special materials, which have better performance and service life compared with the existing galvanized iron wire mesh;

[0026] As a further description of the above technical solution:

[0027] The surface of the second wedge block is sprayed with a polyurethane coating, and the clamping block is made of nitrile rubber;

[0028] The polyurethane coating sprayed on the surface of the second wedge block and the special material of the clamping block enable it to maintain excellent performance even under long-term mortise and tenon connections.

[0029] The utility model has the following beneficial effects:

[0030] In the utility model, after installing two columns, the protective net can be directly placed into the inner walls on the adjacent sides of the two columns, so that the first wedge block is connected to the column by mortise and tenon. Subsequently, the second wedge block is installed. While it forms a mortise and tenon connection with the inner wall of the column itself, the clamping block and the clamping groove also form a mortise and tenon. This fixing method saves time and improves the installation efficiency compared with the existing method of first connecting one side of the column and the fence stably with steel pipes and then installing the other side of the column. At the same time, the side columns and columns here are made of ultra-high performance concrete, effectively preventing the phenomenon of concrete expansion, cracking and peeling caused by the corrosion of steel bars in reinforced concrete, and improving the overall service life.

[0037] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0038] Refer to Figures 1 to 3, an embodiment provided by the utility model: a railway protection concrete fence column, which includes two side columns 1. A protection component is fixedly connected to the adjacent sides of the two side columns 1. The protection component includes a protection net 2. The two sides of the protection net 2 are respectively fixedly connected to the adjacent sides of the two side columns 1. Here, the protection net 2 effectively prevents the intrusion of external personnel or animals, providing a solid defense line for railway safety. The material of the protection net 2 is zinc-aluminum alloy coated steel wire. Here, the zinc-aluminum alloy coated steel wire is a zinc-aluminum mixed rare earth alloy coated steel wire, and its corrosion resistance is 2-3 times higher than that of the pure zinc layer. This material not only performs well in the salt spray test but also shows excellent corrosion resistance in the damp heat and sulfur dioxide gas corrosion tests. In addition, the hot-dip plating temperature of the zinc-aluminum alloy coated steel wire is 40°C lower than that of pure zinc, which helps to improve the mechanical properties of the steel wire. The outer frame material of the protection net 2 is carbon fiber reinforced plastic. Here, the carbon fiber reinforced plastic has the advantages of light weight, high strength, corrosion resistance, and easy processing and forming. Compared with traditional metal materials, they can not only significantly reduce the structural weight but also provide better durability and impact resistance.

[0039] A wedge block 3 is fixedly connected to the outer side of the side column 1. The shape of the wedge block 3 is an outward-expanded trapezoid. This shape is not only beautiful and generous but also can effectively disperse external forces and improve the impact resistance of the column. A clamping groove 4 is opened at the top end of the side column 1. The outer part of the wedge block 3 is tenon-mortise connected to a column body 5. Here, after the wedge block 3 is tenon-mortise connected to the column body 5, due to its special outward-expanded trapezoid shape, the two are more stable and will not fall off easily. The materials of the side column 1 and the column body 5 are ultra-high performance concrete. This material has the characteristics of high strength and good durability, which can ensure that the column is not easily damaged during long-term use and effectively prevent the concrete expansion, cracking, and peeling phenomenon caused by the corrosion of the steel bars in the reinforced concrete, improving the overall service life.

[0040] Refer to Figures 3 to 4, at the top inner wall of the column body 5, there are two plugging components for capping connected by mortise and tenon joints. The plugging component includes the wedge block two 6. The shape of the wedge block two 6 is an outward-expanded trapezoid. The surface of the wedge block two 6 is sprayed with a polyurethane coating. Here, the wedge block two 6 is also designed as an outward-expanded trapezoid to provide a stable mortise and tenon connection. At the same time, polyurethane is a high-performance synthetic material, famous for its excellent weather resistance, wear resistance and elasticity. It can form a tough protective film, effectively preventing fading and aging caused by ultraviolet radiation, and at the same time providing good waterproof performance to protect the side column 1 from moisture erosion. The bottom end of the wedge block two 6 is in contact with the top end of the side column 1, and the top end of the wedge block one 3 is in contact with the bottom end of the wedge block two 6. The outside of the wedge block two 6 is connected to the inner wall of the column body 5 by mortise and tenon joints. Here, a stable mortise and tenon connection can be formed between the wedge block two 6 and the column body 5. The bottom end of the plugging component is fixedly connected with a clamping block 7. The outside of the clamping block 7 is connected to the inner wall of the clamping groove 4 by mortise and tenon joints. The material of the clamping block 7 is nitrile rubber. Here, the clamping block 7 is used to form a stable mortise and tenon connection with the clamping groove 4. At the same time, nitrile rubber is a synthetic rubber with excellent oil resistance, wear resistance and aging resistance. It can maintain good physical properties within a wide temperature range.

[0041] Working principle: First of all, the two side columns 1 serve as the main structure of the column. The protective net 2 can effectively prevent the intrusion of external personnel or animals, providing a solid defense line for railway safety. At the same time, its material, zinc-aluminum alloy coated steel wire, is a zinc-aluminum mixed rare earth alloy coated steel wire, and its corrosion resistance is 2-3 times higher than that of the pure zinc layer of the existing protective net 2. This material not only performs well in the salt spray test, but also shows excellent corrosion resistance in the damp heat and sulfur dioxide gas corrosion tests. In addition, the hot-dip plating temperature of the zinc-aluminum alloy coated steel wire is 40°C lower than that of pure zinc, which helps to improve the mechanical properties of the steel wire. In addition, the outer frame material of the protective net 2 is carbon fiber reinforced plastic, which has the advantages of light weight, high strength, corrosion resistance, easy processing and molding, etc. Compared with traditional metal materials, they can not only significantly reduce the structural weight, but also provide better durability and impact resistance. Then, the shape of the wedge block one 3 on the outside of the side column 1 is an outward-expanded trapezoid. This shape is not only beautiful and generous, but also can effectively disperse external forces and improve the impact resistance of the column.

[0042] Then, the outside of the first wedge block 3 is connected to the column body 5 by a mortise and tenon connection method, making the two more stable and not easily falling off. Finally, the shape of the second wedge block 6 is also designed as an outward-expanded trapezoid, echoing the first wedge block 3. Here, the surface of the second wedge block 6 is sprayed with polyurethane, which is a high-performance synthetic material, well-known for its excellent weather resistance, wear resistance, and elasticity. It can form a tough protective film, effectively preventing fading and aging caused by ultraviolet radiation, while providing good waterproof performance to protect the side column 1 from moisture erosion. The outside of the clamping block 7 is connected to the inner wall of the clamping groove 4 by a mortise and tenon connection method, forming a firm whole. At the same time, because the material of the clamping block 7 itself, nitrile rubber, is a synthetic rubber, it has excellent oil resistance, wear resistance, and aging resistance. It can maintain good physical properties within a wide temperature range; at the same time, the side column 1 and the column body 5 here are made of ultra-high-performance concrete, effectively preventing the phenomenon of concrete expansion, cracking, and falling off caused by the corrosion of steel bars in reinforced concrete, improving the overall service life, and reducing the maintenance and replacement costs.

[0043] When installing this railway protection concrete fence column, all the column bodies 5 can be first fixed on the ground at a certain interval, and then the protective net 2 and the first wedge block 3 on both sides are slid into the top of the column body 5. At the same time, because the shape of the first wedge block 3 is an outward-expanded trapezoid, a stable mortise and tenon connection can be formed between the first wedge block 3 and the column body 5. Then, take the second wedge block 6 and knock it into the inner wall of the column body 5 until it contacts the top of the side column 1. At the same time, the clamping block 7 here will also form a stable mortise and tenon connection with the clamping groove 4. Thus, the installation is completed. This fixing method saves time and improves the installation efficiency compared with the existing method of first connecting one side of the column and the fence with steel pipes and then installing the other side of the column.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
