DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] See also Figure 1-4 The present invention provides a kind of reused central median guardrail, comprising a frame 1 and a pre-buried sleeve 2. The pre-buried sleeve 2 is pre-buried at a designated position on the road surface.

[0023] The first and second end plates 11, 12 are formed from bent steel plates. Two sets of mounting portions 13 and a scrap beam plate 14 are positioned between the first and second end plates 11, 12. The widthwise shapes of the first and second end plates 11, 12 match the shapes of the scrap beam plate 14. The two sets of mounting portions 13 are formed from bent or rolled steel plates. The two ends of the two sets of mounting portions 13 and the scrap beam plate 14 can be welded to the first and second end plates 11, 12, respectively.

[0024] The first end plate 11, the second end plate 12, and the two groups of scrap beams 14 form a storage space 3. At least one first mounting plate 4 is provided in the storage space 3. The shapes of the two sides of the first mounting plate 4 in the width direction match the shapes of the scrap beams 14. The two sides of the first mounting plate 4 can be connected to the two groups of scrap beams 14 by welding. The first mounting plate 4 is provided with columns 5, and the columns 5 are connected to the embedded sleeves 2. Specifically, the first mounting plate 4 is formed by integrally pressing a steel plate. Because multiple first mounting plates 4 are provided in the storage space 3, and each first mounting plate 4 is connected to the two groups of scrap beams 14 on both sides, the first mounting plates 4 can serve as the skeleton of the frame 1, providing excellent support and effectively increasing the strength of the frame 1. Specifically, the scrap beams 14 are discarded two-corrugated steel beams, and the columns 5 are discarded columns 5.

[0025] See also Figures 1 to 3 In order to conveniently open the guardrail of the central dividing strip, in some embodiments of the present application, one end of the column 5 is movably inserted into the embedded sleeve 2, and the other end of the column 5 is provided with a mounting assembly 6, and the end of the column 5 away from the embedded sleeve 2 is detachably connected to the first mounting plate 4 through the mounting assembly 6.

[0026] Specifically, the mounting assembly 6 includes a second mounting plate 61, on which two sets of first limiting portions 62 are arranged in parallel. A first connecting portion 63 is provided at one outward end of the two sets of first limiting portions 62. The first connecting portion 63 is provided with a first mounting hole 64. The first connecting portion 63 is detachably connected to the first mounting plate 4 by means of a first connecting member cooperating with the first mounting hole 64. Specifically, the first connecting member can be a fastening bolt 511, and the first mounting plate 4 is provided with an opening or a threaded hole opposite to the first mounting hole 64. Specifically, the second mounting plate 61 is formed by integrally pressing a steel plate, and the shapes of both sides in the width direction coincide with the shape of the scrap beam plate 14. The limiting portion is made of channel steel, and the first connecting portion 63 is a flat steel plate. The second mounting plate 61, the two sets of limiting portions, and the first connecting portion 63 are welded to form the mounting assembly 6.

[0027] The second mounting plate 61 and the two sets of first limiting portions 62 form a limiting space 65. The end of the column 5 away from the embedded sleeve 2 is located in the limiting space 65 and is connected to the two sets of first limiting portions 62. The first limiting portion 62 can be connected to the outer wall of the column 5 by welding.

[0028] That is to say, the installation component 6 is fixedly mounted on the end of the column 5 away from the embedded sleeve 2 by means of two groups of the first limiting parts 62 fixedly connected to the outer wall of the column 5. The column 5 is connected to the first mounting plate 4 through the installation component 6 fixed on its end. In this way, when it is necessary to open a reused central dividing strip guardrail of the present application, it is only necessary to remove the second connecting member 9 and then rotate the column 5 circumferentially by a certain angle until the limiting component 51 does not interfere with the first limiting part 62, and then the column 5 can be removed from the embedded sleeve 2, so that the reused central dividing strip guardrail of the present application can be easily opened.

[0029] It can be understood that in order to make the connection between the mounting assembly 6 and the column 5 more secure, in some embodiments of the present application, the second mounting plate 61 and the two groups of the first limiting portions 62 are fixedly connected to the end of the column 5 away from the embedded sleeve 2.

[0030] See also Figures 1 to 3In order to conveniently open the guardrail of the central dividing strip, in some embodiments of the present application, the mounting assembly 6 is not fixedly connected to the end of the column 5 away from the embedded sleeve 2, but is detachably connected to the end of the column 5 away from the embedded sleeve 2 by providing a limiting assembly 51 on the end of the column 5 away from the embedded sleeve 2, and the limiting assembly 51 abuts against the first limiting portion 62. The limiting assembly 51 can also serve as a handle for the column 5, supporting the entire guardrail to prevent the vehicle from lowering the overall height of the guardrail when the guardrail collides, causing the vehicle to ride over the guardrail. Preferably, the limiting assembly 51 is arranged in two groups in parallel, and the first limiting portion 62 is located between the two groups of limiting assemblies 51. That is, the upper and lower positions of the column 5 are limited by the two groups of limiting assemblies 51 and the first limiting portion 62, and the left and right positions of the column 5 are limited by the first mounting plate 4 and the second mounting plate 61.

[0031] Specifically, the limiting assembly 51 includes a bolt 511, and a second mounting hole 52 is provided on the column 5. The bolt 511 is movably inserted into the second mounting hole 52. Both ends of the bolt 511 are located outside the column 5 and are screwed with nuts 512. The bolt 511 or the nut 512 abuts against the first limiting portion 62.

[0032] In order to further increase the strength of the frame 1, in some embodiments of the present application, two groups of the mounting portions 13 are provided with mounting positions 131, and reinforcement members 7 are provided in the mounting positions 131. Preferably, the reinforcement members 7 are channel steels.

[0033] In order to facilitate the movement of the frame 1 , casters 8 are provided on the reinforcement 7 .

[0035] Specifically, the second connecting member 9 is a latch, and a first groove 111 and a second groove 121 are respectively provided on the outward outer walls of the first end plate 11 and the second end plate 12, and a third connecting portion 112 and a fourth connecting portion 122 are respectively provided on the first groove 111 and the second groove 121, and a third mounting hole 113 and a fourth mounting hole 123 are respectively provided on the third connecting portion 112 and the fourth connecting portion 122, and the latch is inserted into the third mounting hole 113 and the fourth mounting hole 123.

[0036] The present invention provides a method for reusing a central median guardrail, applying discarded two-corrugated steel guardrails to a frame 1. By arranging an embedded sleeve 2 on the ground, a discarded column 5 is provided on the frame 1, and the frame 1 is installed in the center of the road surface by inserting the column 5 into the embedded sleeve 2. The discarded two-corrugated steel guardrail can be reused to improve the utilization rate of the material. One end of the column 5 is detachably connected to the frame 1 through the installation component 6 and the limiting component 51, and the other end of the column 5 is movably plugged into the embedded sleeve 2 to limit the column 5. The limiting component 51 can also serve as a handle for the column 5 to support the entire guardrail, to prevent the vehicle from lowering the overall height of the guardrail when the guardrail collides, causing the vehicle to ride over the guardrail. In addition, the column 5 can be easily removed to open the central median guardrail. The casters 8 at the bottom of the frame 1 can easily move the central median guardrail. Two or more frames 1 can be detachably connected. In addition to being able to be conveniently connected into a whole, the guardrail can be opened at any section, solving the problem of the inability to balance the integrity of the guardrail connection and the flexibility of opening.
