[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Unless otherwise specified, "plurality" means two or more.
[0021] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0022] like Figure 1As shown, an embodiment of the present invention provides a movable guardrail, including a guardrail 1 and a preset concrete body 2. The guardrail 1 can be set as a corrugated plate structure and adopt a segmented structure. There are guardrail 1 connecting holes 15 between each segmented structure. Specifically, each 12.32-meter guardrail 1 can be arranged in combination with two 6.16-meter preset concrete bodies 2. The guardrail 1 and the movable guardrail 1 can be assembled using an embedded mode.
[0023] like Figure 2 As shown, a mobile guardrail body provided by an embodiment of the present invention includes a preset concrete body 2 and a connecting member and a supporting member arranged on the preset concrete body, wherein the preset concrete body 2 may be a plurality of groups of equally spaced transversely arranged annular steel frame structures 6, and specifically, the plurality of groups of annular steel frame structures may be fixed and connected by a plurality of equally spaced vertically arranged annular structures 7. Figure 8 and Fig.11 To explain, Fig.11 The circled part is the skeleton part of the preset concrete body 2, that is, the preset concrete body skeleton. Figure 8 As indicated therein, the skeleton can be fixed and connected by a plurality of groups of equally spaced transversely arranged annular steel frame structures 6 and a plurality of equally spaced vertically arranged annular structures 7, thereby forming a preset concrete main skeleton 3.
[0024] The above-mentioned connecting member can be used to connect adjacent preset concrete bodies 2, and the internal body is a rectangular frame surrounded by steel bars, in which one side is connected to the connecting portion 4 corresponding to the above-mentioned connecting member, and one side is made into a shape corresponding to the above-mentioned preset concrete body 2 and connected to the above-mentioned preset concrete body 2.
[0025] The supporting member is disposed at the bottom of the preset concrete body 2 and can be used to elevate the preset concrete body 2 so that a water channel is formed between the preset concrete body 2 and the road surface.
[0026] In a possible embodiment, when the cement is poured, the preset concrete body 2 generates an internal recessed portion 9 of a corresponding size and shape according to the shape of the free end of the connecting frame 8 .
[0027] Specifically, the connection area after the above-mentioned preset concrete main body 2, the connecting member and the supporting member are connected together, that is, the skeleton part formed by the connection of the three, is filled by cement pouring. When the recessed part 9 is formed, the shape of the recessed part 9 can be adaptively adjusted according to the connecting frame 8 corresponding to the above-mentioned connecting member to meet the shape of the above-mentioned connecting frame 8.
[0028] By connecting the preset concrete body 2, the connecting members and the supporting members to each other, a complete preset concrete body 2 is quickly assembled. When the adjacent preset concrete bodies 2 are connected by the connecting members, the shape of the recessed part 9 can be adaptively adjusted by the connecting frame 8, so that the stability between the connecting member and the preset concrete body can be enhanced, and the connection strength can be improved. The generated recessed part 9 can also meet the mechanical arm structure of the transfer equipment, so that the mechanical arm can fit the recessed part 9 for transfer operation, thereby improving the convenience during assembly.
[0029] like Fig.10 As shown, the above-mentioned connecting member includes a connecting part 4 and a connecting frame 8, the above-mentioned supporting member includes a ground-inserting member 10 and a supporting base, and the above-mentioned connecting member is arranged on both sides of the above-mentioned preset concrete body. Specifically, the above-mentioned connecting member can be symmetrically arranged along the side surface of the above-mentioned preset concrete body with the center point of the side surface of the preset concrete body as the central axis. Preferably, the central connecting line of the two long axes of the side surface of the preset concrete body can be taken as the center line, and two groups of symmetrically distributed connecting members can be arranged in the upper and lower parts.
[0030] The connecting portion 4 can be used to connect and fix with an adjacent preset concrete body. Specifically, a connecting groove 5 is provided inside the connecting portion 4. Specifically, the opening of the connecting groove 5 is vertically outward along the side of the preset concrete body and is a recessed rectangle, which can be used to accommodate the connecting piece 13.
[0031] A connection hole 15 is provided inside the connection groove 5 on a side connected to another connection groove 5 , and the connection member 13 can be connected to the adjacent connection groove 5 through the connection hole 15 .
[0032] The above-mentioned connecting piece 13 can be selected according to different connection methods, and the above-mentioned connection methods can be divided into bolt connection and embedded connection. Specifically, when the connection method is bolt connection, the connecting piece 13 of the nut and the nut can be used to cooperate with each other, and the adjacent preset concrete bodies can be connected through adjacent connecting holes 15; when the connection method is embedded connection, the connecting piece 13 of the steel section corresponding to the size of the connecting hole 15 can be used, inserted into the adjacent connecting hole 15, and the adjacent preset concrete bodies 10 can be connected.
[0033] By designing the connection holes 15 and coordinating different connection methods, simple assembly and fixation can be achieved, which ensures a tight connection between adjacent preset concrete bodies, enhances the overall stability and durability, and supports rapid installation and disassembly, thereby improving the flexibility and efficiency of on-site operations.
[0034] Specifically, it can be done by Figure 3For illustration, the connection holes 15 have two shapes, one is a first elliptical hole 011 extending longitudinally, and the other is a second elliptical hole 022 extending transversely. The two elliptical holes are arranged relatively on the connection groove 5 .
[0035] Furthermore, according to Fig.14 For illustration, the first elliptical hole 011 is perpendicular to the second elliptical hole 022, and the first elliptical hole 011 and the second elliptical hole 022 on the upper and lower sides are located at a diagonal position, which can realize the fastening of the preset concrete body on a flat road surface to improve the supporting stability of the mobile guardrail; Fig.15 For explanation, the first elliptical hole 011 and the second elliptical hole 022 on the adjacent upper and lower sides can be adjusted to the same side, so as to achieve fine adjustment of the bending of the movable guardrail at the turning point of the road surface or adjust the adjacent preset concrete body.
[0036] like Fig.13 As shown, when the movable guardrail 1 is bent in a turning environment, the connection strength of the connecting member 13 between the adjacent connecting parts 4 can be adjusted according to the bending angle. For example, when bolt connection is used, the connection strength is adjusted by rotating the loose nut to generate a gap between the adjacent connecting parts 4. The connection strength after adjustment can also be compensated by inserting a turning pad 16 into the gap, so that the adjacent preset concrete bodies after the connection strength adjustment will not loosen. It can be understood that the gap generated by the connection strength can be used to perform a turning process on the adjacent preset concrete bodies, and the curvature of the turn can reach between 1-5°, that is, the turning pad 16 can make up for the connection strength gap generated before the curvature of the turn reaches 1-5°.
[0037] By designing adjustable connecting parts 13 and turning pads 16, flexible application at corners is achieved, allowing the guardrail 1 to adjust the connection strength and bending angle as needed in a turning environment. On the premise of reducing the connection strength and increasing flexibility, the turning pad 16 can also make up for the lack of connection strength, which not only ensures the stability and safety of the mobile guardrail 1 when adjusted at different angles, but also improves the applicability of the mobile guardrail 1, so that it can adapt to changing road layouts.
[0038] like Figure 4 As shown, the above-mentioned support member includes two support bases and corresponding ground-inserting members 10. Specifically, the above-mentioned support base can be symmetrically arranged on both sides of the bottom with the midpoint of the side of the above-mentioned preset concrete body as the midline, and two ground-inserting members 10 are provided on each side, which are used to pass through the support base for a distance to contact the ground. The distance can be 1-3cm. It can be understood that the length of the ground-inserting member 10 entering the ground should be less than or equal to 3cm, and the two ground-inserting members 10 can be 3-4cm apart.
[0039] In the portion of the ground-inserting member 10 that passes through the support base, the portion that enters the ground may be a conical structure 17 , and the portion between the ground and the support base may be a cylindrical structure 18 .
[0040] The two symmetrically arranged support bases and the corresponding ground-inserting components 10 provide stability for the mobile guardrail 1, and according to the conical structure 17 and the cylindrical structure 18 of the ground-inserting components 10, they can easily penetrate the ground and evenly disperse the ground pressure. By adjusting the penetration depth and the setting spacing between the ground-inserting components 10, the flexibility and safety of Hunan can be improved, and the damage to the ground can be reduced, so that it can adapt to the setting of the mobile guardrail 1 in different environments.
[0041] like Figure 5 As shown, the support base is provided with a friction pad 12 and a support guard plate 11. Specifically, the friction pad 12 is arranged below the support guard plate 11, and the friction pad 12 and the support guard plate 11 have three corresponding surfaces, each surface is connected one by one, and the whole is trapezoidally connected to the above-mentioned ground-inserting component 10.
[0042] In a possible embodiment, when the longest side of the above-mentioned support guard plate 11 is assembled with an adjacent preset concrete body, the support guard plate 11 corresponding to the longest side can be cut at the midpoint of the longest side to obtain two long-sided support guard plates 11 assembled separately, so as to meet the needs of quick disassembly and assembly for the corresponding adjacent preset concrete bodies.
[0043] The friction pad 12 is made of a flexible modified rubber material and can be pasted to a steel plate or concrete surface with special glue. The three faces of the friction pad 12 are all provided with concave friction pad flanges 19 for wrapping the protruding support guard plate 11, the preset concrete body and the steel bar 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 diamond-shaped lines extending outward from the center of the friction pad 12. The triangular structure in the diamond-shaped lines can enable the friction pad 12 to share the lateral thrust generated when a vehicle collides with its side, thereby increasing the stability of the preset concrete body 2 structure.
[0044] The friction pad 12 is also provided with a ground insertion hole 21 for the ground insertion component 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 component 10. The present embodiment preferably has a circular shape to satisfy the ground insertion component 10 with a conical bottom and a cylindrical top. A certain number of ground insertion holes 21 can be set according to requirements, and the number of the holes may not match the number of the ground insertion components 10.
[0045] After the above-mentioned ground-inserted component 10 is connected to the above-mentioned supporting guard plate 11 through the top steel bar structure 22, the whole is then connected to the above-mentioned preset concrete body.
[0046] By selecting an adaptive friction pad 12 and a corresponding ground-inserting component 10, the purpose of connecting the ground-inserting component 10 to the ground through the friction pad 12 can be met. Since the number of ground-inserting components 10 and the number of ground-inserting holes 21 can be selected according to environmental requirements, there can be spare ground-inserting holes 21. In an environment with a large temperature difference between day and night, these spare ground-inserting holes 21 can provide more expansion space for the material, which helps to deal with the risk of damage to the material due to thermal expansion and contraction. In addition to increasing the grip with the ground and increasing the structural stability between the ground-inserting component 10 and the hole, a drainage gap can be formed with the ground through the spare ground-inserting holes 21, which helps ventilation and drainage and prevents corrosion and water damage.
[0047] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
