For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0051] As shown in Figure 1 The utility model discloses an embodiment provides a mobile guardrail, including guardrail 1 and preset concrete main part 2, above-mentioned guardrail 1 can be set as the corrugated sheet structure, and adopt sectional structure, and each sectional structure has guardrail 1 connecting hole 15 between, specifically, can be set according to every 12.32 meters guardrail 1 with two sections 6.16 meters's preset concrete main part 2 is collocated, and guardrail 1 can use embedded mode and be assembled between mobile guardrail 1.

[0052] As shown in Figure 2 The utility model discloses an embodiment provides a mobile guardrail main part, including preset concrete main part 2 and the connecting component and the support component on preset concrete main part, wherein, above-mentioned preset concrete main part 2 can be the ring steel frame structure 6 with multiple groups of equidistance transverse arrangement, specifically, between multiple groups of ring steel frame structure, can be fixed and connected through multiple groups of equidistance vertical arrangement ring structure 7. Figure 8 And Figure 11 It is explained that, Figure 11 Among them, the circled part is the skeleton part of the above-mentioned preset concrete main part 2, that is, the preset concrete main part skeleton, according to Figure 8 It is explained that, the skeleton can be fixed and connected through multiple groups of equidistance transverse arrangement ring steel frame structure 6 and multiple groups of equidistance vertical arrangement ring structure 7, to form a preset concrete main part skeleton 3.

[0053] The connecting member can be used to connect adjacent preset concrete bodies 2, and the inner body is a rectangular frame formed by a reinforcing bar, one side of which is connected to the connecting part 4 corresponding to the connecting member, and one side is made to correspond to the shape of the preset concrete body 2 and is connected to the preset concrete body 2.

[0054] The support member is arranged at the bottom of the preset concrete body 2 and can be used to lift the preset concrete body 2 to form a water channel between the preset concrete body 2 and the road surface.

[0055] In a possible embodiment, when the cement is poured, the preset concrete body 2 generates an inner recessed part 9 of corresponding size and shape according to the shape of the free end of the connecting frame 8.

[0056] Specifically, when the recessed part 9 is formed by filling the connecting area of the preset concrete body 2, the connecting member and the support member connected together, that is, the skeleton part formed by the connection of the three, the shape of the recessed part 9 can be adjusted according to the connecting frame 8 corresponding to the connecting member to meet the shape of the connecting frame 8.

[0057] By connecting the preset concrete body 2, the connecting member and the support member, a complete preset concrete body 2 can be quickly assembled, and when the connecting member is used to connect adjacent preset concrete bodies 2, the stability between the connecting member and the preset concrete body can be enhanced, the connection strength can be improved, and the recessed part 9 generated can also meet the mechanical arm structure of the transfer device, so that the mechanical arm can be fitted to the recessed part 9 for transfer operation, improving the convenience during assembly.

[0058] As shown in Figure 10 The connecting member includes a connecting part 4 and a connecting frame 8, the support member includes a ground insertion member 10 and a support base, the connecting member is arranged on both sides of the preset concrete body, specifically, the connecting member can be symmetrically arranged along the side surface of the preset concrete body with the center point of the side surface of the preset concrete body as the central axis, and preferably, the connecting member can be arranged in two groups symmetrically arranged on the upper and lower sides with the center connecting line of the two long axes of the side surface of the preset concrete body as the center line.

[0059] The connecting part 4 can be used to connect and fix adjacent preset concrete bodies, and specifically, the connecting part 4 is provided with a connecting groove 5, and specifically, the opening of the connecting groove 5 is vertically outward along the side surface of the preset concrete body and is an inner recessed rectangle, which can be used to accommodate the connecting piece 13.

[0060] Inside the aforementioned connecting groove 5, a connecting hole 15 is provided on the side that connects to another connecting groove 5, through which the aforementioned connector 13 can be connected to the adjacent connecting groove 5.

[0061] The aforementioned connector 13 can be selected according to different connection methods. These connection methods can be divided into bolt connection and embedded connection. Specifically, when the connection method is bolt connection, the connector 13 with nuts and bolts can be used to connect adjacent pre-set concrete bodies through adjacent connection holes 15. When the connection method is embedded connection, the connector 13 with a steel profile corresponding to the size of the connection hole 15 can be used to insert into the adjacent connection hole 15 to connect adjacent pre-set concrete bodies 10.

[0062] By using the design of the connecting hole 15 and different connection methods, simple assembly and fixing can be achieved. This ensures a tight connection between adjacent pre-cast concrete bodies, enhances the overall stability and durability, and also supports quick installation and disassembly, improving the flexibility and efficiency of on-site operations.

[0063] Specifically, it can be done through, for example Figure 3 To explain, the shape of the connecting hole 15 includes two types: a first elliptical hole 011 that extends longitudinally and a second elliptical hole 022 that extends laterally. These two types of elliptical holes are arranged opposite each other on the connecting groove 5.

[0064] Furthermore, it can be based on Figure 14 The first elliptical hole 011 is perpendicular to the second elliptical hole 022, and the positions of the first elliptical holes 011 and the second elliptical holes 022 on the upper and lower sides are diagonally opposite, which can achieve the fastening of the pre-set concrete body on a flat road surface, thereby improving the support stability of the movable guardrail; as follows: Figure 15 The explanation is as follows: by adjusting the positions of the first elliptical hole 011 on the adjacent upper and lower sides and the second elliptical hole 022 to be on the same side, the bending of the movable guardrail at the road bend or the adjustment of the adjacent preset concrete body can be realized.

[0065] like Figure 13As shown, when the above-mentioned mobile guardrail 1 is bent in a turning environment, the connection strength of the connecting piece 13 between the adjacent connecting parts 4 can be adjusted according to the bending angle. For example, when using bolt connection, the connection strength can be adjusted by rotating the nut, so that a gap is generated between the adjacent connecting parts 4. The adjusted connection strength can be compensated by inserting a turning pad 16 in the gap, so that the adjacent preset concrete bodies with adjusted connection strength will not be loose. It can be understood that the gap generated by the above-mentioned connection strength can be used for turning processing of the adjacent preset concrete bodies, and the turning degree can be between 1-5°, that is, the turning pad 16 can compensate for the connection strength gap before the turning degree reaches 1-5°.

[0066] By designing the adjustable connecting piece 13 and the turning pad 16, flexible application at the corner is realized, allowing the guardrail 1 to adjust the connection strength and bending angle as needed in a turning environment. Under the premise of reducing the connection strength and increasing flexibility, the connection strength gap can also be compensated by the turning pad 16, which not only ensures the stability and safety of the mobile guardrail 1 during different angle adjustments, but also improves the applicability of the mobile guardrail 1, making it adaptable to various road layouts.

[0067] As shown in Figure 4 The support member includes two support bases and corresponding ground insertion members 10. Specifically, the support bases can be symmetrically arranged on both sides of the bottom with the midpoint of the side of the preset concrete body as the center line, and each side is provided with two ground insertion members 10 for contacting the ground through the support base by a distance of 1-3 cm. It can be understood that the length of the ground insertion member 10 entering the ground should be less than or equal to 3 cm, and the distance between the two ground insertion members 10 can be 3-4 cm.

[0068] In the part of the ground insertion member 10 penetrating the support base, the part entering the ground can be a conical structure 17, and the part between the ground and the support base can be a cylindrical structure 18.

[0069] The two symmetrically arranged support bases and corresponding ground insertion members 10 provide stability for the mobile guardrail 1. According to the conical structure 17 and the cylindrical structure 18 of the ground insertion member 10, the ground can be easily penetrated and the ground pressure can be evenly distributed. By adjusting the penetration depth and the arrangement distance between the ground insertion members 10, the flexibility and safety of the mobile guardrail 1 can be improved, and the damage to the ground can be reduced, making it adaptable to the mobile guardrail 1 setting in different environments.

[0070] As shown in Figure 5As shown, the support base is provided with a friction pad 12 and a support guard 11. Specifically, the friction pad 12 is arranged below the support guard 11, and both the friction pad 12 and the support guard 11 have three corresponding surfaces, each of which is connected one by one, and the whole is trapezoidal, and is connected with the above-mentioned ground insertion member 10.

[0071] In a possible embodiment, the longest side of the support guard 11 is cut at the midpoint of the longest side when assembling adjacent predetermined concrete bodies, so as to obtain two long-sided support guards 11 for split assembly, so as to meet the quick disassembly requirement of assembling adjacent predetermined concrete bodies.

[0072] The friction pad 12 is made of flexible modified rubber material, which can be pasted with steel plate or concrete surface by special glue. The three surfaces of the friction pad 12 are provided with recessed flanges 19 for wrapping the protruding support guard 11, the predetermined concrete body and the reinforcing material, thereby improving the safety and firmness of the support base. More specifically, the friction pad 12 is also provided with friction lines 20, which are rhombic lines extending outward from the center of the friction pad 12. The triangular structure in the rhombic lines can distribute the lateral thrust generated when a vehicle collides with the side of the friction pad 12, thereby increasing the stability of the structure of the predetermined concrete body 2.

[0073] The friction pad 12 is also provided with a ground insertion hole 21 for the ground insertion member 10 to pass through the friction pad 12 and contact the ground. Specifically, the shape of the ground insertion hole 21 can be designed according to the selected ground insertion member 10. In this embodiment, the circular shape is preferred to meet the shape of the bottom tapered and top cylindrical ground insertion member 10. A certain number of ground insertion holes 21 can be provided according to the requirements, and the number of holes can not match the number of ground insertion members 10.

[0074] The ground insertion member 10 is connected with the support guard 11 through the top reinforcing structure 22, and then connected with the predetermined concrete body.

[0075] By selecting the appropriate friction pad 12 and corresponding ground insertion member 10, the purpose of connecting the ground insertion member 10 with the ground through the friction pad 12 is met. Because the number of ground insertion members 10 and the number of ground insertion holes 21 can be selected according to the environmental requirements, there may be spare ground insertion holes 21. In the environment with large day and night temperature difference, these spare ground insertion holes 21 can provide more expansion space for the material, which helps to cope with the damage risk of the material when it expands due to heat and shrinks due to cold. In addition to increasing the grip with the ground and increasing the structural stability, the ground insertion member 10 and the hole can also form a drainage gap with the ground through the spare ground insertion hole 21, which helps to ventilate and drain water, preventing corrosion and water damage.

[0076] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, wherein the same parts are denoted by the same reference numerals. Therefore, any equivalent changes made on the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
