[0002] With the expansion of my country's expressway network, the frequency and scale of road reconstruction and expansion projects are increasing. Expressway reconstruction and expansion projects often employ a "construction while traffic continues" approach, which requires the installation of guardrails on the outer side of the construction road to ensure the safety of construction personnel and machinery while allowing vehicle traffic. However, existing guardrail structures, while providing protection, cause significant damage to the road surface. Utility Model Content

[0003] This utility model provides a guardrail structure that balances protective capabilities with minimal damage to the road surface.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A guardrail structure includes multiple reinforced concrete panels and multiple support bases. The multiple reinforced concrete panels and multiple support bases are arranged sequentially along the length direction of the guardrail structure. Adjacent reinforced concrete panels are detachably connected by connecting components. The reinforced concrete panels have anti-collision surfaces and back surfaces that are opposite to each other in the width direction of the guardrail structure. The multiple support bases are all located on the back surface of the reinforced concrete panels away from the anti-collision surfaces, and any reinforced concrete panel abuts against at least two support bases.

[0006] The support base includes a first horizontal plate, a second horizontal plate, and a back plate, all of which are rectangular, and also includes at least three vertical plates. The back plate is used to abut against the back of the corresponding reinforced concrete railing. The first horizontal plate and the second horizontal plate are located on the same side of the back plate, facing each other and having the same length. The first horizontal plate is connected to the top edge of the back plate, and the second horizontal plate is connected to the bottom edge of the back plate. The width of the first horizontal plate is smaller than the width of the second horizontal plate. Any vertical plate is a right-angled trapezoidal plate. At least three vertical plates are arranged sequentially along the length of the guardrail structure. Any vertical plate is perpendicular to the second horizontal plate and the back plate, and any vertical plate is connected between the first horizontal plate, the second horizontal plate, and the back plate. The second horizontal plate is used to connect to the road surface by bolts.

[0007] Optionally, the width of the upper edge of the upright plate is the same as the width of the first horizontal plate, and the width of the lower edge of the upright plate is the same as the width of the second horizontal plate.

[0008] Optionally, the support base includes three upright plates along the length of the guardrail structure, one of which is located on the first side of the first horizontal plate and the second horizontal plate, another upright plate is located on the second side of the first horizontal plate and the second horizontal plate, and the remaining upright plate is located in the middle of the second horizontal plate.

[0009] Optionally, the portion of the second horizontal plate located between two adjacent vertical plates is provided with four through holes arranged in an array.

[0010] Optionally, the connecting assembly includes a first connecting plate having two first connecting holes arranged along the length of the guardrail structure, the two first connecting holes being opposite to one of two adjacent reinforced concrete guardrail panels; each first connecting hole corresponds to a first screw, the shank of the first screw passing through the corresponding first connecting hole and connecting to the corresponding reinforced concrete guardrail panel.

[0011] Optionally, the connecting assembly includes a second connecting plate having two second connecting holes arranged along the length of the guardrail structure, each second connecting hole being opposite to one of two adjacent reinforced concrete guardrail panels; each second connecting hole corresponds to a second screw, the shank of the second screw passing through the corresponding second connecting hole and connecting to the corresponding reinforced concrete guardrail panel.

Detailed Implementation

[0021] This application provides a guardrail structure including guardrail panels and multiple posts. The posts are arranged sequentially along the length of the guardrail structure, and each post is inserted into the road surface and connected to the back of the guardrail panel. The back of the guardrail panel refers to the side of the guardrail panel opposite the crash surface. To achieve the effect of reinforcing the guardrail panel and ensuring sufficient protective capacity, the outer diameter of the posts is usually relatively large. This results in the need to dig relatively large holes in the road surface to insert the posts, causing greater damage to the road surface. Significant road surface damage not only requires a longer road repair time but also incurs higher repair costs.

[0022] Based on this, embodiments of this application provide a guardrail structure that balances protective capabilities with minimal damage to the road surface.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Figure 1 This illustration shows a three-dimensional structural diagram of a guardrail structure provided in an embodiment of this application. Figure 2 This is a side view of a guardrail structure provided in an embodiment of this application. Figure 1 and Figure 2 As shown in the illustration, the guardrail structure provided in this application includes multiple reinforced concrete panels 1 and multiple support bases 2. The multiple reinforced concrete panels 1 and the multiple support bases 2 are arranged sequentially along the length direction A of the guardrail structure. Adjacent reinforced concrete panels 1 are detachably connected by connecting components 3. Each reinforced concrete panel 1 has an anti-collision surface 11 and a back surface 12 facing each other in the width direction B of the guardrail structure. The multiple support bases 2 are all located on the back surface 12 of the reinforced concrete panel 1, facing away from the anti-collision surface 11, and each reinforced concrete panel 1 abuts against at least two support bases 2.

[0025] The support base 2 includes a first horizontal plate 21, a second horizontal plate 22, a back plate 23, and at least three vertical plates 24. The first horizontal plate 21, the second horizontal plate 22, and the back plate 23 are all rectangular. The back plate 23 abuts against the back side 12 of the corresponding reinforced concrete railing 1. The first horizontal plate 21 and the second horizontal plate 22 are located on the same side of the back plate 23; obviously, both the first horizontal plate 21 and the second horizontal plate 22 are located on the side of the back plate 23 away from the reinforced concrete railing 1. Furthermore, the first horizontal plate 21 and the second horizontal plate 22 are directly opposite each other, and their lengths are the same. The first horizontal plate 21 is connected to the top edge of the back plate 23, and the second horizontal plate 22 is connected to the bottom edge of the back plate 23. The width of the first horizontal plate 21 is less than the width of the second horizontal plate 22. Each vertical plate 24 is a right-angled trapezoidal plate. These at least three vertical plates 24 are arranged sequentially along the length direction A of the railing structure, and each vertical plate 24 is perpendicular to both the second horizontal plate 22 and the back plate 23. Each upright plate 24 is connected between the first horizontal plate 21, the second horizontal plate 22, and the back plate 23. The second horizontal plate 22 is used to connect to the road surface via bolts. It is easy to understand that the upper edge (the upper base of the trapezoid) of the upright plate 24 is connected to the first horizontal plate 21, the lower edge (the lower base of the trapezoid) of the upright plate 24 is connected to the second horizontal plate 22, and the right-angled side between the upper and lower edges of the upright plate 24 is connected to the back plate 23. The length directions of the first horizontal plate 21 and the second horizontal plate 22 are parallel to the length direction A of the guardrail structure; the width directions of the upright plates, the first horizontal plate, and the second horizontal plate are parallel to the width direction B of the guardrail structure; and the height direction of the upright plates is parallel to the height direction C of the guardrail structure.

[0026] In this design, the support base 2 is fixed to the road surface with bolts. On one hand, the combined weight of the reinforced concrete parapet 1 and the supporting function of the support base 2 provides good impact resistance and sufficient protection. On the other hand, while achieving the same fixing effect as inserting posts into the road surface, this design uses a second horizontal plate 22 of the support base 2 to connect to the road surface with bolts, resulting in smaller and shallower holes in the road surface and less damage. Therefore, road repair is easier, takes less time, and is less costly.

[0027] In addition, the guardrail structure is easy to install on site and convenient to disassemble and transport.

[0028] For example, the width of the upper edge of the upright plate 24 is the same as the width of the first horizontal plate 21, and the width of the lower edge of the upright plate 24 is the same as the width of the second horizontal plate 22.

[0029] In one specific implementation, the support base 2 includes three upright plates 24 to provide sufficient support while saving costs. Further, along the length A of the guardrail structure, one upright plate 24 is located on the first side of the first horizontal plate 21 and the second horizontal plate 22, another upright plate 24 is located on the second side of the first horizontal plate 21 and the second horizontal plate 22, and the remaining upright plate 24 is located in the middle of the second horizontal plate 22. In this way, on the one hand, the support base 2 forms a circumferentially closed structure, resulting in stronger structural stability; on the other hand, the three upright plates 24 are evenly spaced on the second horizontal plate 22, allowing the support base 2 to provide more balanced support. Furthermore, the upright plate 24 located in the middle of the second horizontal plate 22 acts as a reinforcing rib along the length of the second horizontal plate 22, further improving the structural strength of the support base 2. This provides sufficient support to the reinforced concrete guardrail 1 with a minimal number of upright plates 24, making the guardrail structure more impact-resistant. Of course, in other embodiments, the support base 2 may also include four, five, or more upright plates 24.

[0030] like Figure 3 As shown, in some examples, the portion of the second horizontal plate 22 located between two adjacent vertical plates 24 is provided with four through holes 221 arranged in an array. This means that the support base 2 is connected to the road surface by at least four bolts M arranged in an array. In this design, the connection between the support base 2 and the road surface is more reliable. It is easy to understand that the aforementioned through holes 221 on the second horizontal plate 22 are connected to the road surface by bolts.

[0031] For example, bolt M can be a chemical bolt, an expansion bolt, or the like.

[0032] Please return Figure 1 In some embodiments, the connecting component 3 includes a first connecting plate 31, which has two first connecting holes 311 arranged along the length direction A of the guardrail structure. The two first connecting holes 311 are respectively opposite to one of two adjacent reinforced concrete guardrail panels 1. Each first connecting hole 311 corresponds to a first screw, and the screw thread passes through the corresponding first connecting hole 311 to connect with the corresponding reinforced concrete guardrail panel 1, thereby realizing a detachable connection between two adjacent reinforced concrete guardrail panels 1.

[0033] Furthermore, in some embodiments, the connecting component 3 includes a second connecting plate 32 having two second connecting holes 321 arranged along the length direction A of the guardrail structure. Each of the two second connecting holes 321 corresponds to one of two adjacent reinforced concrete guardrail panels 1. Each second connecting hole 321 corresponds to a second screw, the shank of which passes through the corresponding second connecting hole 321 and connects to the corresponding reinforced concrete guardrail panel 1, thereby making the connection between the two adjacent reinforced concrete guardrail panels 1 more secure.

[0034] It is easy to understand that the first connecting plate 31 and the second connecting plate 32 are arranged sequentially along the height direction C of the guardrail structure.

[0035] In some embodiments, in the height direction C of the guardrail structure, both the first connecting plate 31 and the second connecting plate 32 are located directly above the support base 2 to increase the strength of the connection between two adjacent reinforced concrete guardrail panels 1. Exemplarily, the support base 2 includes three upright plates 24 along the length direction of the guardrail structure, wherein one upright plate 24 is located on the first side of the first horizontal plate 21 and the second horizontal plate 22, another upright plate 24 is located on the second side of the first horizontal plate 21 and the second horizontal plate 22, and the remaining upright plate 24 is located in the middle of the second horizontal plate 22. The support base 2 is symmetrically arranged about the joint surfaces of two adjacent reinforced concrete guardrail panels 1.

[0036] In some embodiments, the support base 2 is a steel support base. The steel support base has higher structural strength and can provide better support for the reinforced concrete railing 1, thereby ensuring the impact resistance of the railing structure. Exemplarily, the first horizontal plate 21 and the second horizontal plate 22 are welded to the back plate 23; the upright plate 24 is also welded to the first horizontal plate 21, the second horizontal plate 22, and the back plate 23.

[0037] The guardrail structure provided in this application embodiment can be used for protection in highway construction areas. Specifically, the guardrail structure is installed on the outer side of the construction road to isolate the construction area from the vehicle traffic road, thus protecting vehicle safety and the construction area. The guardrail structure uses reinforced concrete panels 1, reinforced by steel support bases 2 on the back. In some embodiments, the protection level can reach Class A, significantly improving the protection capability for medium-sized buses and large trucks, better maintaining vehicle trajectory, and protecting the facilities and personnel safety in the construction area. Furthermore, after the highway reconstruction and expansion project is completed, the reinforced concrete panels 1 can be transferred without damage to the central median strip and subsequently used as a Class A central median guardrail, effectively improving resource utilization.

[0038] The following is combined with Figure 2 and Figure 3 The dimensions of a guardrail structure provided in an embodiment of this application are described below. For example... Figures 1 to 3As shown, in this guardrail structure, the length of any reinforced concrete panel 1 is 4000 mm, the height H1 is 1100 mm, and the bottom width W1 is 275 mm. At 175 mm, the reinforced concrete panel 1 has a first inclined surface 111 sloping towards the support base 2. The height of the first inclined surface 111 is 180 mm, and the width is 125 mm. The top end of the first inclined surface 111, facing the top of the reinforced concrete panel 1, is connected to a second inclined surface 112 sloping towards the support base 2. The height of the second inclined surface 112 is 526 mm. The height H2 of the support base 2 is 500 mm. The width W2 of the second horizontal plate is 300 mm, and the length L2 is 500 mm. The width of the first horizontal plate 21 is 102 mm, and the length is 500 mm. The thickness of the first horizontal plate 21, the second horizontal plate 22, the back plate 23, and each upright plate 24 is 8 mm or 9 mm.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
