[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] like Figure 1-Figure 2 As shown, the road guardrail for bridge construction provided in the embodiment of the present application includes a column 100, a limit end 300, a wire rope 200, a node beam 400 and a spiral spring 600, wherein the column 100 is a component for supporting and fixing the guardrail structure, and is used to connect and fix various parts of the guardrail. In this embodiment, two columns 100 are fixed side by side on the ground, and there is a certain preset distance between the two columns 100.
[0029] In this embodiment, with the front of the guardrail as the reference plane, a plurality of node beams 400 are arranged transversely between the two columns 100, and adjacent node beams 400 are in contact with each other, and the node beams 400 are also in contact with the wall surfaces of the two columns 100. In addition, two upper and lower rows of node beams 400 are arranged between the two columns 100, and a vertical guardrail 500 is fixedly arranged between the upper and lower rows of node beams 400. Preferably, the node beams 400 and the vertical guardrail 500 can be integrally formed, so that the structural strength of the guardrail can be improved.
[0030] The steel wire rope 200 passes through the first column 100 and the multiple node beams 400 arranged transversely, and passes through the wall of the second column 100. The total length of the steel wire rope 200 is greater than the preset distance between the two columns 100. The limit end 300 is fixedly arranged at both ends of the steel wire rope 200, and a spiral spring 600 is sleeved on a section of the steel wire rope 200 located outside the column 100. The spiral spring 600 is respectively in contact with the limit end 300 and the wall of the column 100. When the spiral spring 600 is in a normal state, the steel wire rope 200 between the multiple node beams 400 can be tightened, so that the multiple node beams 400 can contact each other and maintain a transverse arrangement state.
[0031] In the road guardrail for bridge construction provided in the embodiment of the present application, a plurality of node beams 400 formed by splicing are arranged between two columns 100, a steel wire rope 200 is inserted between the plurality of node beams 400, and the plurality of node beams 400 are arranged between the two columns 100 through the steel wire rope 200. At the same time, the steel wire rope 200 also penetrates the column 100 and extends to the outside thereof, and a limited end 300 is arranged at the end of the steel wire rope 200. A spiral spring 600 is also sleeved on the outside of the steel wire rope 200, and the spiral spring 600 is respectively abutted against the limited end 300 and the column 100. This makes it possible that when a vehicle collides with the guardrail, the plurality of node beams 400 will be disconnected, and the steel wire rope 200 and the limited end 300 squeeze the spiral spring 600 to achieve buffering. The above structural design can effectively reduce the impact force generated after the vehicle collides with the guardrail, thereby reducing damage to the vehicle. In addition, the individual node beams 400 may be replaced according to the actual damage conditions, thereby greatly reducing the maintenance cost of the guardrail.
[0032] In some embodiments, a support plate 700 is provided at the bottom end of the column 100, and the outer diameter of the support plate 700 is greater than the outer diameter of the bottom surface of the column 100. The support plate 700 can increase the contact area between the column 100 and the ground, thereby ensuring that the column 100 can be stably set on the ground. Preferably, the support plate 700 is slidably provided with a rotating screw 800 along the thickness direction, and the rotating screw 800 is vertically arranged on the ground. A drill bit is provided at the bottom end of the rotating screw 800, and the rotating screw 800 can be screwed into the ground through the drill bit to further improve the stability of the guardrail.
[0033] In some embodiments, a screw bolt 900 is threadedly connected to the wall surface where the column 100 and the wire rope 200 are connected, and a hole is provided at the center of the screw bolt 900, through which the screw bolt 900 is passed through the wire rope 200. The nut head of the screw bolt 900 contacts the end of the spiral spring 600, and the length of the screw bolt 900 extending into the column 100 can be changed by rotating the screw bolt 900, thereby adjusting the length of the spiral spring 600. Through this structural design, the elastic force of the spiral spring 600 can be adjusted according to actual conditions, so that the guardrail can cope with different collision situations.
[0034] In some embodiments, the vertical guardrail 500 may be a plate-like structure, and the vertical guardrail 500 is obliquely disposed between the upper and lower node beams 400. Figure 1 and Figure 2 As shown. Through the above structural design, since the vertical guardrail 500 is tilted between the node beams 400, when a vehicle collides with the vertical guardrail 500, the vertical guardrail 500 will first drive the node beam 400 to twist, and then pull the wire rope 200 to shrink the spiral spring 600 to produce a buffer. In this way, the twisting of the vertical guardrail 500 and the node beam 400 can provide a pre-buffering effect for the vehicle, thereby further protecting the vehicle from being damaged by a large impact.
