[0002] Highway reconstruction and expansion projects often employ a "construction while traffic continues" approach, requiring both safe and smooth vehicle traffic and the safety of construction workers and machinery. To meet this requirement, the use of construction zone guardrails is becoming increasingly widespread. However, existing construction zone guardrails are revealing growing problems. For example, most steel structure guardrails require intermittent anchoring to the road surface, resulting in poor mobility and potential damage to the asphalt pavement during removal, leading to high road repair costs. Utility Model Content

[0003] This utility model provides a guardrail structure to improve the problems of steel structure guardrails needing to be anchored to the road surface at intervals, having poor mobility, and being prone to damaging the asphalt road surface when dismantled.

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

[0005] A guardrail structure includes a base, a protective plate, and multiple posts. The base includes multiple base bodies arranged sequentially along the length of the guardrail structure. Any two adjacent base bodies include a first base body and a second base body arranged along the length of the guardrail structure. The end of the first base body that is connected to the second base body has a first overlapping portion, and the end of the second base body that is connected to the first base body has a second overlapping portion. The first overlapping portion and the second overlapping portion are arranged in the height direction of the base.

[0006] The plurality of posts are arranged sequentially along the length of the guardrail structure. Each base body is detachably connected to at least two posts, and each first overlap and the second overlap opposite to the first overlap in the height direction of the base are detachably connected by at least one post. The height of the posts is greater than the height of the base, and the protective plate is detachably connected to the end of the plurality of posts away from the base.

Detailed Implementation

[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 paper shows a front view of a guardrail structure provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a three-dimensional representation of the base 1 in the guardrail structure. It is easy to understand that the length of the guardrail structure can be... Figure 1 and Figure 2 The direction of C can also be Figure 1 and Figure 2 The opposite direction of direction C; in the following text, only the length direction of the guardrail structure is considered. Figure 1 and Figure 2 Let's take the C direction as an example for explanation.

[0025] like Figure 1 and Figure 2As shown in the illustration, an embodiment of this application provides a guardrail structure including a base 1, a protective plate 2, and multiple posts 3. The base 1 includes multiple base bodies 11 arranged sequentially along the length C of the guardrail structure. Any two adjacent base bodies 11 include a first base body 11a and a second base body 11b arranged along the length of the guardrail structure. The end of the first base body 11a that connects to the second base body 11b forms a first overlapping portion 11a1, and the end of the second base body 11b that connects to the first base body 11a forms a second overlapping portion 11b1. The first overlapping portion 11a1 and the second overlapping portion 11b1 are arranged in the height direction of the base 1. The multiple posts are arranged sequentially along the length of the guardrail structure. Each base body 11 is detachably connected to at least two posts 3, and each first overlapping portion 11a1 and a second overlapping portion 11b1 opposite to the first overlapping portion 11a1 in the height direction of the base 1 are detachably connected by at least one post 3. In other words, besides being detachably connected to the column 3 at least at the first overlapping portion 11a1 and the second overlapping portion 11b1, other parts of the base body 11 can also be detachably connected to the column 3. For example, as... Figure 1 and Figure 2 As shown, the base body 11 has a connecting hole in the middle of the length direction of the guardrail structure, and the column 3 is inserted into the connecting hole for detachable connection with the base body 11. Furthermore, the height of the column 3 is greater than the height of the base 1, and the protective plate 2 is detachably connected to the end of each column 3 away from the base 1.

[0026] It is easy to understand that the height of the base 1, the height of the column 3, and the height of the base body 11 mentioned below, as well as the heights of the first overlapping part 11a1 and the second overlapping part 11b1, are all based on the perspective of the guardrail structure when it is in the application scenario.

[0027] In the guardrail structure provided in this embodiment, the base 1 is assembled from multiple base bodies 11, and the connections between the base bodies 11, between the posts 3 and the base bodies 11, and between the posts 3 and the protective plate 2 are all detachable, making the installation of the guardrail structure simpler. When the guardrail structure needs to be moved, the connections between adjacent base bodies 11, between posts 3 and the base bodies 11, and between the posts 3 and the protective plate 2 can be disconnected, and then each component can be moved. The guardrail structure is easy to disassemble, has good mobility, and is convenient for transportation. In addition, there is no anchoring between the base body 11 and the road surface, so it will not damage the road surface, saving the cost of road repair and anchoring structures, making the cost of the guardrail structure lower.

[0028] In specific implementation, the first overlapping portion 11a1 may be located above the second overlapping portion 11b1, or the second overlapping portion 11b1 may be located above the first overlapping portion 11a1. The projections of the first overlapping portion 11a1 and the second overlapping portion 11b1 on the horizontal plane may coincide, and the projection of the first overlapping portion 11a1 on the horizontal plane may also be within the range of the projection of the second overlapping portion 11b1 on the horizontal plane, or the projection of the second overlapping portion 11b1 on the horizontal plane may be within the range of the projection of the first overlapping portion 11a1 on the horizontal plane.

[0029] In some possible implementations, the first overlapping portion 11a1 overlaps with the second overlapping portion 11b1, and the sum of the heights of the first overlapping portion 11a1 and the second overlapping portion 11b1 is equal to the height of the base 1, so that the strength of the base 1 is more uniform and the strength of the guardrail structure is more balanced. For example, the first base body 11a includes a first main body portion 11a2 and the aforementioned first overlapping portion 11a1. The first overlapping portion 11a1 is connected to the end face of the first main body portion 11a2 facing the second base body 11b, and the top surface of the first overlapping portion 11a1 is in the same plane as the top surface of the first main body portion 11a2. The second base body 11b includes a second main body portion 11b2 and the aforementioned second overlapping portion 11b1. The second overlapping portion 11b1 is connected to the end face of the second main body portion 11b2 facing the first base body 11a, and the bottom surface of the second overlapping portion 11b1 is in the same plane as the bottom surface of the second main body portion 11b2. It is easy to understand that the heights of the first overlapping part 11a1 and the second overlapping part 11b1 are both less than the height of the base 1.

[0030] In some embodiments, the first overlapping portion 11a1 and the second overlapping portion 11b1 are at the same height, so that the forces on the first base body 11a and the second base body 11b at the overlapping point are more similar, and the connection reliability of the first base body 11a and the second base body 11b is stronger. Of course, in other embodiments, the heights of the first overlapping portion 11a1 and the second overlapping portion 11b1 may not be the same.

[0031] For example, in one specific embodiment, the bottom surface of the base 1 is used to contact the road surface, and the top surface of the base 1 is used to be parallel to the road surface.

[0032] In some embodiments, the bottom surface of the second overlap portion 11b1 includes a flat portion and a recessed portion 111. The flat portion is used to contact the road surface, and the recessed portion 111 is recessed toward the top surface of the second overlap portion 11b1. The recessed portion 111 can be used for drainage to reduce the possibility of water accumulation on the road surface.

[0033] In one specific implementation, the height of the recess 111 is less than half the height of the base 1 to ensure the strength of the base 1.

[0034] In some embodiments, each first overlapping portion 11a1 and the second overlapping portion 11b1 opposite to the first overlapping portion 11a1 in the height direction of the base 1 are detachably connected by a column 3, thereby ensuring the structural strength of the base 1 as much as possible. Of course, in other embodiments, one or more first overlapping portions 11a1 and the second overlapping portions 11b1 opposite to the first overlapping portion 11a1 in the height direction of the base 1 may be detachably connected by two or more columns 3.

[0035] Exemplarily, a through hole 11a11 is formed on the first overlapping portion 11a1, and the through hole 11a11 penetrates the first overlapping portion 11a1 along its height direction. It is easy to understand that the axial direction of the through hole 11a11 is parallel to the height direction of the base. A blind hole 11b11 is formed on the second overlapping portion 11b1, and the axis of the blind hole 11b11 coincides with the axis of the through hole 11a11, with the open end of the blind hole 11b11 facing the first overlapping portion 11a1. The bottom end of the column 3 passes through the through hole 11a11 and is inserted into the blind hole 11b11, and the column 3 forms an interference fit with at least one of the through hole 11a11 and the blind hole 11b11. In order to make the connection between the column 3 and the base 1 more secure, in some embodiments, the column 3 forms an interference fit with both the through hole 11a11 and the blind hole 11b11. The column 3 and the base 1 are detachably connected by an interference fit, which not only makes the connection between the two more convenient, but also reduces the number of parts in the guardrail structure, which is conducive to cost saving.

[0036] In some embodiments, each base body 11 is made of reinforced concrete. The reinforced concrete base body 11 is relatively heavy, and its own weight can ensure the stability of the guardrail structure.

[0037] In some embodiments, the guardrail structure includes two protective plates 2, which are distributed on both sides of the post 3 in a first direction D, and both protective plates 2 are connected to the post 3. The first direction is perpendicular to both the axial direction of the post 3 and the longitudinal direction C of the guardrail structure. This design ensures greater strength of the guardrail structure and provides two impact surfaces, allowing both sides of the guardrail structure to serve as the downward direction for vehicles, thus broadening its applicability. Exemplarily, each protective plate 2 is connected to the post 3 via a screw and nut assembly m.

[0038] For example, such as Figure 4 and Figure 5As shown, in one specific implementation, the protective plate 2 includes multiple two-wave plates, with adjacent two-wave plates overlapping each other and connected by multiple pairs of screw and nut assemblies m. This solution can effectively reduce the overall weight of the guardrail structure, and the two-wave plates and the bottom reinforced concrete base body 11 work together to share the load, enabling the guardrail structure to achieve a higher protection level (up to Class A).

[0039] For example, the guardrail structure includes a plurality of anti-glare panels 4, which are arranged sequentially along the length direction C of the guardrail structure, and each anti-glare panel 4 is connected to the protective plate 2.

[0040] The following describes a guardrail structure provided in an embodiment of this application. Figures 1-5 In this guardrail structure, the base body 11 has a length, width, and height of 500 mm, 500 mm, and 4000 mm, respectively. The uprights 3 are cylindrical, with an outer diameter of 140 mm, a wall thickness of 4.5 mm, and a height of 970 mm. After the uprights 3 are installed on the base 1, the depth h of the uprights 3 inserted into the base body 11 is 420 mm, and the height of the uprights 3 and the base 1 is 1050 mm. The sum of the heights of the two wave plates, the uprights 3, and the base 1 is 1050 mm. The distance L1 between two adjacent uprights 3 is 2000 mm. The height of the two wave plates is 310 mm, the dimension of the two wave plates in the first direction D is 85 mm, and the plate thickness is 4 mm. The height of the anti-glare plate 4 is 850 mm, and the distance L2 between two adjacent anti-glare plates 4 is 1000 mm. Yellow and black reflective film or reflective paint can be pasted on the sides of the base body 11.

[0041] The guardrail structure provided in this application embodiment is applicable to asphalt pavements and can be used for protection in highway construction areas. For example, the guardrail structure is installed on the outer side of the construction road, thereby isolating the construction road from the vehicle traffic road, achieving the function of protecting vehicle driving safety and protecting the construction area. In addition, the guardrail structure provided in this embodiment can be reused after dismantling, which can improve resource utilization and reduce pollution and carbon emissions.

[0042] 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.
